Behold, Slap! It's a language chimera:

• terse: tacit like APL, J, K
• safe: strong linear type system like Rust
• small: simple spec like Lisp, Forth
• fast: manual memory like C, Zig
• easy: managed effects like Elm, Roc

Terse

Slap is a stack language. Postfix syntax is ugly, but powerful:

-- twenty fibonacci numbers (no recursion)
0 1 20 (swap over plus) repeat drop 
  6765 eq assert

I'll eventually add Uiua-esque glyphs so you can feel like a wizard:
0 1 20 (: ↷ +) ⍥ ↘ 2765 = !

Those who abhor tacit stack manipulation can use let instead:

-- sum of squares (tacit)
[1 2 3 4 5] 
  (sqr) map sum
  55 eq assert

-- sum of squares (explicit)
[1 2 3 4 5] 
  0 ('x let 'y let x x mul y plus) fold
  55 eq assert

Safe

Slap's true power is what it cannot do.

Parametric types (à la Hindley–Milner) prevent mismatched data:

[1] [2.0] cat
-- TYPE ERROR: type variable conflict
--   expected: int list
--   got:      float list

Linear types (i.e. Rust-like borrow checker) protect allocated memory from leakage, corruption, meddling, and abandonment. You cannot duplicate nor discard a pointer (box):

42 box dup
-- TYPE ERROR: dup requires copyable type, got box

42 box drop
-- TYPE ERROR: drop requires copyable type, got box

For boxes, you must lend, mutate, clone, or free:

-- borrow a read-only snapshot with lend
[1 2 3] box 
  (len) lend 
  3 eq assert free

-- mutate in place
[1 2 3] box 
  (4 give) mutate 
  (len) lend 
  4 eq assert free

-- clone into two independent boxes
[1 2 3] box 
  clone
    (4 give) mutate
    (len) lend 
    4 eq assert free
  () lend 
  3 eq assert free

This API prevents classic problems like double-free, use-after-free, and forgot-to-free.

Linear types are also great for file handles and thread coordination. Stay tuned!

Slap's stacks are flexible. You can safely use them as tuples or closures without confusing the type system:

-- it's a tuple
(1 2) apply plus
  3 eq assert

-- it's a closure
'make-adder ('n let (n plus)) def
  5 make-adder 3 swap apply
  8 eq assert

-- it's a function
(1 plus) (2 mul) compose (3 sub) compose (sqr) compose
  5 swap apply 
  81 eq assert

In some languages you can declare function types. Typed stack languages have a similar concept called "stack effects". The Slap type-checker automatically infers these for you, but you may add them for extra clarity/enforcement:

-- double = n -> n * 2
'double (2 mul) def

-- square : int -> int
-- square = n -> n * n
'square (dup mul) 
  [int lent in  int move out] 
    effect check def

Slap's annotations are expressive enough to describe exotic stack effects:

-- no effect
'noop () [] effect check def

-- return multiple values
'hello-world ("hello" "world") 
  [str move out  str move out] 
    effect check def

-- linear parametric effect
'pal
  ((dup reverse cat) mutate) 
  [ 'a list 't own in  
    'a list 't own out ]
    effect check def

Fast

No garbage collection! No secret allocations! Everything sits on the stack (unless you send it to the heap in a box).

The stack is often slower than the heap. Slap's transparent semantics forces you to reason about such tradeoffs.

Slap has fast solutions to most of the first fifty Project Euler problems. Here are the first ten:

Small

slap.c is ~2,000 miserable lines of C99.

Could be smaller too -- I'm convinced I can shave another ~500 lines without sacrificing readability or performance.

It's a lexer, a typechecker, and a stack evaluator.

If Slap's architecture can fit in my pea-sized brain, it will surely fit in yours too.

Easy

Slap has pixels! Build with make slap-sdl (native) or make slap-wasm (browser) to get a 640x480 canvas with 2-bit grayscale.

The runtime and lo-fi aesthetics were inspired by Uxn. Go check it out!

tl;dr:

1. Defer US taxes by reinvesting your taxable income into the economy as business expenses, depreciating assets, etc.
2. For your leveraged investments, pay yourself in refinanced cash when your investments appreciate and/or credit rates drop.

You can dodge defer US taxes if you reinvest your dollars into the economy. This is no loophole; the system is working as intended. Your government wants you to create taxable wealth.

Equity is taxable wealth that already exists. You cannot create wealth by purchasing $10k of AAPL equity. You can create wealth by investing $10k in an apple orchard.

But you must reinvest your dollars in a particular way that Uncle Sam understands. When you report business expenses on your tax return, you inform the IRS what you spent on enterprise. The US tax code rewards entrepreneurial pursuits which grow the economy. Uncle Sam happily forgoes $1 now for $11 next decade -- it's the same slice from a larger pie.

To perpetually defer taxes on your taxable wealth, keep reinvesting your surplus. The IRS forgoes $10 now for $110 next decade, $100 for $1,100, and so on.

If you aren't actually reinvesting capital, pay your damn taxes. Don't be an asshole.

Depreciation spreads business expenses over time. If you invest $100 in a lawnmower that earns $11 per year, this depreciation schedule will minimize your total taxable income each year:

But you can also ask the IRS to treat it as $10/year for 10 years rather than $11/year for 9 years. You might consider this schedule if your other investments lost $11 this year:

Let's say your other investments gain $89 this year, so you front-load the lawnmower depreciation schedule. You pay zero taxes this year, but you've increased your tax obligations in future years:

To defer taxes, deduct yesterday's expenses from today's revenue. Good accountants will massage depreciation schedules to match unexpected profits/losses.

Example: Instead of depreciating a building over 27.5 or 39 years, a cost segregation study could reclassify components (carpeting, fixtures, landscaping, certain electrical) into 5, 7, or 15-year assets. In this way, a $2M property could accrue $200K–$300K in depreciation deductions its first year.

Again, this is intentional. If you contribute more to the US economy than you siphon out, your government will happily pretend you're penniless.

A politician attracts investments into their constituency via tax incentives. Unfortunately, some tax incentives are loopholes which invite crooks to claim exemptions without truly contributing. It is difficult to distinguish whether a loophole is corrupt or negligent, and impossible to prosecute politicians either way.

Most investment money is borrowed (e.g. SBA loans, commercial real estate loans). Your government wants you to create wealth, so it loans money to banks at a magic interest rate. Banks may lend that money to you at a higher rate.

If you contribute loaned wealth to the US economy, you must siphon your dollars out in a way that Uncle Sam understands. One popular method is refinancing, i.e. paying off your old loan with a new loan and pocketing the cash difference. Loaned money isn't taxable income, so you can save/spend it without affecting your tax rate.

Disclaimer: Loans ain't free. Refinancing ain't easy.

Death is a popular escape from deferred taxes. When you die, your obligations to the government vanish. Your heirs inherit assets/property at market value. Their assets depreciate from new cost bases.

According to Modern Monetary Theory, taxes are a method of pulling dollars out of circulation. The government never actually needed your money anyway.

Your life on Earth continues long after you die. Every dollar you've spent, saved, borrowed, lent, donated, willed -- it all mattered. People will commute on the roads you paid for, or taste apples from your trees, or pollute the Pacific Ocean, or survive tuberculosis, or eat pasta, or overdose on fentanyl, or play chess, or gossip, or whatever people do.

Am I really a "customer" when they charge -0.01% interest to hold my money?

BofA is clunky. Their physical branches seem simultaneously overstaffed and understaffed. Everybody there is cordial yet confused. I would never visit their physical locations if their app worked, but alas, their app is crap. I cannot open/close accounts, I cannot reliably cash checks, I cannot easily transfer money -- the software might just be ornamental.

But it ain't 2010 anymore. We now have branchless banks like Ally, SoFi, and maybe even Robinhood. Online-only banking alternatives offer 3%+ APY in lieu of physical locations. According to science, paying region-locked human staffers to occupy an expensive retail space full of money costs a fortune.

Sometimes these banks are technically not banks -- they're "financial services companies with trusted banking partners".

I use Mercury for business banking. It's great. When I discovered that Mercury offers personal banking, I was cautiously optimistic. They built a successful B2B product, but companies usually botch expansions from B2B into B2C.

Oracle's graveyard of B2C products remains a trove of cautionary tales.

My wife and I opened a joint account in minutes. Mercury onboarded us individually and then instantly approved us. I transferred the money via their BofA Plaid integration -- no routing numbers needed, thank you sir. Smooth.

Bonus points: Mercury did not send me a trillion "PLEASE TAKE OUR SURVEY" emails.

I'm eager to test the following features after our money lands:

• enforce spending limits on debit cards
• automate stuff via the Mercury API
• schedule monthly rent payments to our landlord
• match receipts via email (for which I plan to automate forwarding from my FastMail account)
• filter transactions by merchant, user, etc.
• connect to the official Mercury MCP server

If you can survive without physical branches, consider parking your money in Mercury too.

I had a nifty game idea while Ivan Reese was trying to explain Death Stranding 2 to me. Here's the gist:

• In the beginning, you control a lone robot in an isolated corner of a vast dark map.
• Your robot randomly follows roads. It passes refineries, mines, and shops. You cannot instruct the robot where to go, but you can instruct it to grab/drop resources as it meanders by.
• By transporting ore to refineries, and then trading refined metal at shops, you can purchase repair kits and other modules.
• Repair kits allow you to revive broken robots and recruit them to your team.
• Robots navigate the map according to their navigation module(s): some robots will follow mining routes, others will seek conflict, others will follow friends.
• Reprogram robot behavior by equipping new modules. You can acquire new modules via scavenging, engineering, trade, and theft.
• As you explore the map, you discover the Eastern forest kingdom and the Western seaside kingdom.
• The roads connecting these kingdoms are brimming with activity as military skirmishes ramp up into full-blown war.
• How will you participate in the conflict? Will you become a kingmaker? Broker peace? Rule the world?

In its current form, Last Mile is fun for almost five whole minutes. Try it yourself. There's definitely a great game somewhere in here, but I'm not sure if it's worth pursuing. I'd love to hear what y'all think! Feel free to email me at [email protected].

Haskell-esque languages may look alike, but they differ across many dimensions:

• strict vs. lazy
• curried vs. bland
• bootstrapped vs. hosted
• interpreted vs. compiled
• nominal vs. structural types
• pretty vs. ugly errors

Most implementations use standard compilation phases:

1. Lexing: Source → Token stream
2. Parsing: Tokens → Surface AST
3. Desugaring: Surface AST → Core AST
4. Type Inference: Core AST → Typed AST
5. Pattern Match Compile: Typed AST → Case trees
6. Normalization (ANF/K): Typed AST → Normalized IR
7. Optimization: Normalized IR → Normalized IR
8. Closure Conversion: Normalized IR → Closure-explicit IR
9. Code Generation: Closure IR → Target (asm/bytecode/C/LLVM)
10. Register Allocation: Virtual regs → Physical regs (if native)
11. Runtime System: GC, primitives, entry point

Strict vs. Lazy

In strict evaluation, arguments are evaluated before being passed to a function. In lazy evaluation, arguments are only evaluated if their value is actually needed; the result is cached, so the work happens at most once.

-- lazy eval returns `3` without applying `foo`
length [ 1, foo 2, 4 ]

Strict evaluation is the simple choice. If you want laziness, Peyton Jones's STG machine is the standard approach. MicroHs sidesteps the STG machine by compiling directly to combinatory logic with graph reduction.

Lazy evaluation also unlocks infinite collections — you can define an infinite list and consume only what you need.

Curried vs. Bland

In a curried language, f x y is ((f) x) y: two function applications. If your backend doesn't detect that f always takes two arguments (arity analysis), you pay for a heap allocation on every multi-argument call.

Bootstrapped vs. Hosted

I tried to teach myself to play the guitar. But I'm a horrible teacher — because I do not know how to play a guitar.

— Mitch Hedberg

Most compilers are written in an existing language (e.g. C, Rust, Haskell, OCaml) and lean on that host's ecosystem for parsing libraries, build tools, and package management.

A bootstrapped compiler compiles itself. You write the compiler in the language it compiles, then use an earlier version of the compiler (or a minimal seed runtime) to build the next version. Your language becomes self-sustaining; the compiler is its own test suite.

There are many exemplary self-hosted languages to study:

• MicroHs is a Haskell compiler that compiles Haskell to combinators. The combinator reducer is implemented in C. The compiler is written in Haskell and can compile itself. Bootstrapping requires only a C compiler -- no pre-existing Haskell installation.
• Ben Lynn starts with a minimal runtime in C (~350 LOC), then constructs increasingly capable compilers, each written in the subset that the previous one can compile. Each stage is ~100–300 LOC of the language being defined. The total chain is ~2000 LOC + 350 LOC C.

  C runtime (350 LOC)
    → compiler₁: lambda calculus + integers
    → compiler₂: + let, letrec, ADTs
    → compiler₃: + type inference
    → compiler₄: + pattern matching
    → compiler₅: + type classes
    → ...
    → compilerₙ: near-Haskell-98

• Newt is a dependently typed language whose compiler is written in Newt, targeting JavaScript. It bootstraps by keeping the generated JS checked in. This works best when your target is a high-level runtime (JS, JVM) rather than native code.

Interpreted vs. Compiled

An interpreter executes the program directly by walking its AST or stepping through bytecode. A compiler translates the program into another language (e.g. x86, C, JS) and lets that target handle execution.

The boundary here is blurry. Bytecode VMs compile to an intermediate form. "Transpilers" compile to source code rather than machine instructions.

Lil' fun langs are usually interpreters. Without compilation, you can skip closure conversion, register allocation, and runtime systems. The leap from interpreter to compiler costs ~500–2000 LOC.

Nominal vs. Structural Types

type Meters  = Int
type Seconds = Int

-- Nominal:     Meters ≠ Seconds  (different names)
-- Structural:  Meters = Seconds  (same shape)

Most ML-family languages are nominal for algebraic data types but structural for records (if implemented). Row polymorphism (EYG, Grace, Koka) is inherently structural -- it acts on "any record with at least these fields." Simple-sub goes further: union and intersection types, with principal inference intact.

Pretty vs. Ugly Errors

-- Ugly:
Error: type mismatch: int vs string

-- Pretty:
 3 │ let x = 1 + "hello"
   │             ^^^^^^^^
Error: I expected an `int` here, but got a `string`.
  The left side of `+` is `int`, so the right side must be too.

Pretty errors cannot be achieved with a coat of paint. To point at a line/region of code, you must thread source locations through every compiler phase. A minimum viable error system:

1. Source spans on every AST node. Every expression, pattern, and type carries { file, start_line, start_col, end_line, end_col }. This costs one extra field per node.
2. Preserve spans through desugaring. When you lower where to let, the new let node inherits the span of the where.
3. Preserve spans through type inference. When unification fails, you need the spans of both conflicting types.
4. Format errors with context. Show the source line, underline the relevant span, explain the mismatch.

Lexing

Optional enhancements:

• Layout/indentation sensitivity (Haskell-style offside rule): Ben Lynn implements this in later bootstrapping stages. MicroHs includes full layout parsing. Adds 100–300 LOC. The algorithm is well-described by the Haskell Report's Section 2.7.
• Unicode identifiers: Most small compilers skip this entirely. Koka supports it.
• Interpolated strings: Syntax like "hello ${name}" is not standard in ML-family, but some newer languages add it.

Parsing

Parsing converts the flat token stream into a tree. The surface syntax is parsed into a concrete syntax tree (CST) or directly into an abstract syntax tree (AST). ML-family languages have a well-behaved grammar that is almost LL(1).

Every subsequent phase transforms this type. In ML-family languages, the AST typically looks like:

type expr =
  | Lit of literal                    (* 42, 3.14, "hello", true *)
  | Var of name                       (* x *)
  | App of expr * expr                (* f x *)
  | Lam of name * expr                (* fun x -> e *)  (or \x -> e)
  | Let of name * expr * expr         (* let x = e1 in e2 *)
  | LetRec of name * expr * expr      (* let rec f = e1 in e2 *)
  | If of expr * expr * expr          (* if c then t else f *)
  | Tuple of expr list                (* (a, b, c) *)
  | Match of expr * branch list       (* match e with p1 -> e1 | ... *)
  | Ann of expr * type                (* (e : t) *)

Name Resolution & Desugaring

Before type inference, the surface AST is simplified:

1. Alpha-renaming: Every binder is assigned a unique identifier to eliminate shadowing. MinCaml's Rust port does this during type checking. Most do this while parsing or during a separate pass.
2. Fixity resolution: Infix operators are re-associated according to declared precedence and associativity. HaMLet does this as a separate pass. Many small compilers hardcode operator precedence in the parser.
3. Desugaring: Surface constructs are lowered into core constructs:
   • where clauses → let
   • Guards in pattern matching → nested if
   • do notation (monadic) → >>= chains
   • List comprehensions → concatMap
   • Operator sections → lambdas: (+ 1) becomes fun x -> x + 1
   • Record syntax → positional constructors + accessor functions
   • Type class instances → dictionary passing (elaboration)

Type Inference

This is the heart of an ML-family language. The "standard" algorithm is Hindley-Milner (HM) type inference, specifically Algorithm W or Algorithm J.

Core components:

1. Type representation: Types are terms built from type variables, type constructors, and function arrows: type ty = TVar of tvar | TCon of string | TArr of ty * ty | TTuple of ty list
2. Unification: Given two types, find the most general substitution that makes them equal. Implemented as a union-find structure over type variables with occurs-check.
3. Generalization: At let boundaries, free type variables in a type are universally quantified to produce a polymorphic type scheme: ∀α. α → α.
4. Instantiation: When a polymorphic name is used, its scheme is instantiated with fresh type variables.

-- Given:
let id = fun x -> x in (id 1, id true)

-- Type inference trace:
-- 1. id : α → α                (infer: x has fresh type α, body is x)
-- 2. generalize: id : ∀α. α → α    (α is free at let boundary)
-- 3. id 1:  instantiate α=β, unify β→β with int→γ, get int
-- 4. id true: instantiate α=δ, unify δ→δ with bool→ε, get bool
-- 5. result: (int, bool)

But fancy type system features aren't free:

Other strategies:

• Polymorphism: Monomorphic type inference only (no ∀ quantification). Every type is fully determined. This cuts the type checker to ~100 LOC by eliminating generalization and instantiation entirely. Functions like id x = x get a concrete type at each use site.
• Elaboration: Modern type checkers increasingly separate elaboration (translating surface syntax to a fully explicit core) from unification (solving type constraints). The Elaboration Zoo demonstrates this cleanly: each stage is a single Haskell file of 200–800 LOC, progressively adding features.
• Type class desugaring via dictionary passing: Haskell-style type classes are implemented by translating class constraints into explicit dictionary arguments. sort :: Ord a => [a] -> [a] becomes sort :: OrdDict a -> [a] -> [a]. Ben Lynn's compiler and MicroHs both use this approach.

Pattern Match Compilation

With types inferred, pattern matching can be compiled to efficient decision trees or case trees.

Key phases:

1. Exhaustiveness checking: Warn/error if a match doesn't cover all cases.
2. Redundancy checking: Warn if a pattern is unreachable.
3. Guard compilation: Guards add a "backtrack" obligation.
4. Nested pattern flattening: (Cons (x, Cons (y, Nil))) → sequence of tests.

The canonical reference is Compiling Pattern Matching to Good Decision Trees. Luc Maranget's algorithm produces provably optimal decision trees in terms of the number of tests. OCaml and Rust use this approach.

Normalization

-- Before (nested expression):
f (g x) (h y)

-- After (A-normal form):
let a = g x in
let b = h y in
f a b

Every intermediate value gets a name. Every function argument becomes trivial. Evaluation order is now explicit in the let chain.

Normalization strategies:

Optimization

With the program in normal form, optimization passes can simplify it. In small compilers, optimizations are kept minimal -- the goal is to not be embarrassingly slow, not to compete with GCC.

MinCaml's optimization passes (totaling ~300 LOC):

These six passes cover 80%+ of the optimization value for a small compiler. They are applied iteratively until a fixpoint is reached (typically 2–3 iterations).

Beyond the basics:

Closure Conversion

-- Before:
let f = \ x -> x + y

-- After:
let f = 
  { fun = \ env x -> x + env.y
  , env = { y = y } 
  }

The optimized IR still has functions with free variables. Closure conversion makes all functions "closed" -- because hardware doesn't understand lexical scoping. Every function becomes a pair: (code pointer, environment record). The environment captures the function's free variables at the point of definition.

Code Generation

Codegen is wholly determined by your choice of target:

Register Allocation

Programs use arbitrarily many variables, but CPUs have a fixed number of registers. Register allocation decides which variables live in registers and which spill into memory.

If you target native assembly, you implement this yourself. The backend handles this for you if you target C/LLVM/Cranelift/etc.

Runtime System

The minimal setup includes:

Lil' fun langs allocate frequently -- every closure, every cons cell, every partial application. Without reclamation, you run out of memory fast. You need to prevent garbage from accumulating:

If your language has algebraic effects (Eff, Frank, Koka, Ante), the runtime needs support for delimited continuations or a CPS-transformed calling convention. Effect handlers essentially require a second stack or a segmented stack to capture continuations. Koka handles this via evidence-passing; Eff and Frank use interpretation.

That's right. My phone sends annoying text messages to my friends if I don't log a workout by 3PM.

Try it yourself. To add friends as spam targets, write "Tattle." somewhere in their contact notes. Use "Automations" in the Shortcuts app to trigger it on a recurring schedule.

It's strange how this motivates me -- I'm not seeking encouragement nor validation here. My brain simply converts the situation to "I must do pushups to save my friends from my spam robot".

Whatever works.

I adore small programming languages. Iota is two combinators. tinylisp is 99 lines of C. milliForth is 340 bytes. Fractran multiplies fractions. Oh, K?

I've encountered tiny implementations of Forth, Lisp, C, Prolog, etc., but never "milliHaskell".

Yes, I'm still slowly working on scrapscript.

ML-style languages carry a pungent monad odor that attracts mathochists. Notable examples include Haskell, Elm, F#, Scala, and OCaml. They're "Lambda Calculus with syntactic sugar", i.e. functional and statically-typed. Most implementations extend Hindley-Milner type inference with algebraic data types, pattern matching, and closures:

• Elaboration Zoo: progressive dependent type checking implementations, each a single Haskell file of 200–800 lines, from basic NbE through holes, implicit arguments, and first-class polymorphism.

🤖 The most extreme capability-to-size ratio in this list — a complete Calculus of Constructions (the type theory at the top of the lambda cube) with bidirectional typing, dependent function types, and a type-in-type universe, all in a single OCaml gist of ~60–80 lines. It can express length-indexed vectors and other dependently typed programs. Not ML-family per se, but it demonstrates that full dependent types need not be complex to implement.

Harrop MiniML

🤖 MiniML demonstrates the absolute floor for a native-code ML compiler. Using Camlp4 for parsing and OCaml's LLVM bindings, it supports integer arithmetic, conditionals, and recursive first-order functions. Xavier Leroy noted the critical caveat: this is not truly "Mini-ML" since it lacks higher-order first-class functions — adding closures and garbage collection would significantly expand the codebase. Still, it shows what LLVM enables in ~100 lines.

lambda-calculus-hs

🤖 A progressive collection of single-file lambda calculus implementations in Haskell (~200–900 LOC each) by Solomon Bothwell. Starts with simply typed evaluation and builds incrementally through bidirectional typechecking, normalization by evaluation (NbE), System T, records with depth subtyping, and nominal inductive types with dependent pattern matching. Each implementation is self-contained. Where tomprimozic/type-systems varies the inference algorithm, this repository varies the type system while keeping bidirectional checking as the constant.

THIH

🤖 Typing Haskell in Haskell by Mark P. Jones is the definitive executable specification of Haskell 98's complete type system in just 429 lines of core Haskell. It covers kinds, qualified types, type classes, pattern matching types, binding groups, mutual recursion, and defaulting. For context, the Hugs type checker implementing the same semantics spans 90+ pages of C. THIH is a type checker only (no evaluation), but its density of specification per line of code is unmatched.

Simple-sub

🤖 ~500 LOC of Scala. Lionel Parreaux's clean reimplementation of Stephen Dolan's MLsub — algebraic subtyping that adds union and intersection types to Hindley-Milner while preserving principal types. No annotations required. The original MLsub won POPL 2017; Simple-sub distills it into an ICFP 2020 Pearl that's small enough to read in one sitting. The ancestor of MLscript, which grows the idea into a full language with OOP and TypeScript interop.

• Paper: "The Simple Essence of Algebraic Subtyping" (ICFP 2020)

PLZoo poly

🤖 ~400–600 LOC, OCaml. Implements a lazy, purely functional language with parametric polymorphism and HM type inference. Its sibling miniml (~300–500 LOC) includes a compiler targeting an abstract machine. Both are part of Andrej Bauer's Programming Languages Zoo, which contains 12+ miniature language implementations, each a few hundred lines of OCaml, covering everything from untyped lambda calculus to call-by-push-value.

• Website: plzoo.andrej.com
• Repo: github.com/andrejbauer/plzoo

EYG

🤖 ~500 LOC JavaScript interpreter, full implementation in Gleam. EYG ("Eat Your Greens") by Peter Saxton prioritizes predictability, portability, and crash-free programs. It uses row-typed inference (HM extended with row polymorphism), algebraic effects as the sole FFI mechanism, and closure serialization — functions can be sent to other machines for tierless client/server programming. The most distinctive feature: programs are stored as JSON ASTs, not text files. A structural editor makes it impossible to write syntactically invalid programs.

Pico-ml

🤖 An OCaml subset with HM type inference that compiles to WebAssembly, implemented in TypeScript. Small and self-contained — unusual for having a TypeScript host language rather than the OCaml/Haskell norm. A good starting point if you want to understand ML compilation targeting the browser.

• Repo: github.com/Quramy/pico-ml

TinyML

🤖 <700 LOC, Standard ML. Packs a lexer, parser, interpreter, and full polymorphic HM type checker into under 700 lines of SML. Referenced on Lambda the Ultimate, this may be the smallest complete implementation with genuine Hindley-Milner inference, though the original download link appears to have gone stale.

• Reference: lambda-the-ultimate.org/node/2683

Eff

🤖 The original algebraic effects language (2012) by Andrej Bauer and Matija Pretnar. OCaml syntax with effect handlers as first-class constructs — you declare effect operations, then install handlers that give them meaning. This is where the idea was first made concrete in a running implementation. Koka, Frank, OCaml 5's effect handlers, and virtually every subsequent algebraic effects system trace lineage here.

• Repo: github.com/matijapretnar/eff
• Paper: "Programming with Algebraic Effects and Handlers" (2012)

Frank

🤖 "Do Be Do Be Do" (POPL 2017) by Sam Lindley, Conor McBride, and Craig McLaughlin. A strict effectful functional language where functions are handlers that handle zero effects — and multihandlers generalize function abstraction to handle multiple effect interfaces simultaneously. The insight: the boundary between "function" and "effect handler" is artificial. Implemented in Haskell. Lindley describes it as "the one I'm most fond of" while noting it's "basically unmaintained." That tension between conceptual elegance and practical neglect is the story of many languages on this list.

• Paper: "Do Be Do Be Do" (POPL 2017)

Grace

🤖 A JSON superset with bidirectional type checking and row polymorphism, by Gabriella Gonzalez (author of Dhall). Designed explicitly as a "ready-to-fork" language skeleton — if you need a typed DSL, clone Grace and customize it. Has open records, open unions (polymorphic variants), and a clean Haskell codebase that reads like a tutorial. No Hindley-Milner per se (bidirectional instead), but closely related.

• Blog: haskellforall.com/2021/09/fall-from-grace-ready-to-fork.html

Hackett

🤖 A Haskell-like language implemented entirely as Racket macros via the "Type Systems as Macros" technique, by Alexis King. Bidirectional type inference, algebraic datatypes, pattern matching, typeclasses, higher-kinded types, and higher-rank polymorphism — all implemented not as a separate type-checker pass but as macro expansion. The meta-angle is the story: types as macros rather than a traditional elaboration pipeline.

• Repo: github.com/lexi-lambda/hackett
• Paper: "Type Systems as Macros" (POPL 2017)

Scrapscript

🤖 A content-addressable pure functional language where every expression reduces to a cryptographic hash, stored in a decentralized "scrapyard" registry and referenced by hash or alias. The implementation is a ~1,300-line dependency-free Python interpreter in a single file, with a baseline compiler to C (~500 LOC) and an SSA IR with SCCP/DCE optimization (~1,000 LOC). Pattern matching is the sole control-flow mechanism. Compiles to C, WebAssembly, and Cosmopolitan portable executables. Implemented primarily by Max Bernstein.

• Repo: github.com/tekknolagi/scrapscript
• Blog series: Max Bernstein's implementation walkthroughs at bernsteinbear.com/blog/scrapscript/

MinCaml

🤖 ~2,000 LOC, OCaml → native code. The gold standard for capability-to-code-size ratio. Written by Eijiro Sumii at Tohoku University, it implements a strict, higher-order functional language with type inference, closures, tuples, arrays, tail-call optimization, inline expansion, constant folding, and graph-coloring register allocation. It compiles to SPARC, PowerPC, and x86 assembly. On benchmarks including a ray tracer, MinCaml-compiled code runs within 2× of GCC and OCaml's ocamlopt — sometimes faster. The deliberate trade-off: it omits polymorphism, algebraic data types, and pattern matching. Used in undergraduate compiler courses at the University of Tokyo since 2001, where students build ray tracers compiled by their own compilers running on custom CPUs.

Ben Lynn

🤖 ~2,000 lines of Haskell + 350 lines of C. Arguably the most remarkable bootstrapping achievement in this space. Starting from a 350-SLOC C runtime that interprets combinatory logic, Lynn builds a chain of approximately 20 progressively more capable compilers, each written in the subset of Haskell that the previous compiler can handle. The final compiler supports type inference, type classes, algebraic data types, pattern matching, guards, where clauses, monadic I/O, modules, and layout parsing — approaching Haskell 98 coverage. It compiles Haskell to combinatory logic via Kiselyov's bracket abstraction algorithm, with graph reduction evaluation. Later stages even target WebAssembly. The entire bootstrapping chain is reproducible from just a C compiler.

1ML

🤖 ~3,000–5,000 LOC, OCaml. Andreas Rossberg unified ML's core and module layers into a single language where modules are first-class values, types are values, and functors are ordinary functions. It elaborates to System Fω with HM-style inference. Won the ICFP Most Influential Paper Award in 2025. A proof-of-concept interpreter, not optimized, but a conceptual breakthrough in minimal surface area.

• Repo: github.com/rossberg/1ml
• Paper: "1ML — Core and modules united" (ICFP 2015, JFP 2018)

mlml

🤖 A self-hosting OCaml subset compiler targeting native x86-64. ~3,000–5,000 LOC. Supports pattern matching, algebraic data types, recursive functions, and closures. Does not implement type inference — it demonstrates the minimum OCaml subset needed for self-compilation.

• Repo: github.com/coord-e/mlml

Dhall

🤖 A total (non-Turing-complete) typed configuration language. ~4K LOC core Haskell. Normalization is guaranteed to terminate — you can always reduce a Dhall expression to a normal form, which means imports resolve, functions inline, and what you get is plain data. Based on a Calculus-of-Constructions-derived type theory with records, unions, and natural numbers. Has a formal specification and implementations in Haskell, Rust, Go, and Clojure.

• Website: dhall-lang.org

Ante

🤖 Combines HM type inference, algebraic data types, pattern matching, algebraic effects, and an ownership-like system for shared mutability. Written in Rust, it uses Cranelift for native code generation. Actively developed, aiming to bridge the Rust/OCaml divide.

• Repo: github.com/jfecher/ante

Tao

🤖 Surprisingly feature-rich for its size: generics, typeclasses, sum types, pattern matching, first-class functions, currying, algebraic effects, associated types, and totality checking. Its pipeline runs from lexing through HIR type inference to MIR monomorphization and bytecode execution. Written in Rust.

• Repo: github.com/zesterer/tao

Austral

🤖 A systems language with linear types and capability-based security. The linear type checker is ~600 lines. OCaml bootstrap compiler targeting C. Designed by Fernando Borretti to fit in one person's head — the spec is deliberately small enough that a single developer can understand the entire language. Not functional in the Haskell sense, but linear types make it adjacent. An experiment in "what if we took linear types seriously but kept the language small."

• Repo: github.com/austral/austral
• Website: austral-lang.org

AQaml

🤖 A self-hosting OCaml subset compiler targeting native x86-64. ~5,000–8,000 LOC. Adds records, variants, references, and garbage collection beyond what mlml supports. Triple self-hosting verified. Like mlml, it omits type inference — demonstrating the minimum OCaml needed for self-compilation.

• Repo: github.com/ushitora-anqou/aqaml

Borgo

🤖 Adds ML-family features (algebraic data types, exhaustive pattern matching, Result/Option types) to Go's ecosystem by compiling to Go source code with Rust-like syntax. Written in Rust.

• Repo: github.com/borgo-lang/borgo

polytt

🤖 A research experiment from the Topos Institute extending Martin-Löf Type Theory with native, first-class polynomial functors — the mathematical objects underlying deterministic state machines and interactive systems. Written in OCaml with Menhir parsing. Custom syntax for polynomial types (y^n), morphism arrows, and wiring operators. Dependent types (Pi, Sigma), finite-set ADTs, and pattern matching via case elimination. An ended experiment, but a unique point in the design space: what happens when you make polynomial functors a language primitive rather than an encoding.

• Repo: github.com/ToposInstitute/polytt

Newt

🤖 ~7K LOC, self-hosted, compiles to JavaScript. A dependently typed language with Agda/Idris/Haskell-like syntax by Steve Dunham. Bidirectional typechecking with normalization by evaluation (based on Elaboration Zoo), typeclasses, ADTs with dependent pattern matching, case tree compilation, trampoline-based TCO for mutually tail-recursive functions, and erasure of compile-time-only values (0/ω quantities). Has a web playground and an LSP. The compiler is written in Newt itself. Built as a learning exercise, but the feature set — self-hosting, dependent types, typeclasses, erasure, LSP — puts it well beyond most pedagogical implementations.

• Playground: dunhamsteve.github.io/newt

HaMLet

🤖 ~10,000–15,000 LOC, SML. Andreas Rossberg's most faithful implementation of the Definition of Standard ML. It implements all of SML '97 including the full module system (signatures, structures, functors), mapping rule-by-rule to the formal Definition. Jeremy Yallop recommends it as the most readable SML implementation. It can be bundled into a single SML file and compiled by any SML implementation. A compile-js branch demonstrates compilation to JavaScript.

• Repo: github.com/rossberg/hamlet

SOSML

🤖 ~10,000–15,000 LOC, TypeScript. Implements the full SML core language in the browser: val/fun/datatype declarations, pattern matching, HM type inference, exceptions, and references. Used for teaching at Saarland University.

• Website: sosml.org
• Repo: github.com/SOSML/SOSML

MicroHs

🤖 By Lennart Augustsson (one of GHC's original creators) — the most complete "small" Haskell compiler alive today. It compiles an extended subset of Haskell 2010 including type classes, do-notation, deriving, record syntax, overloaded literals, and modules. It is fully self-hosting and — critically — bootstrappable from only a C compiler (no pre-existing Haskell toolchain required). MicroHs translates Haskell to combinators executed by a C runtime. It has a JavaScript runtime target, a package manager (mcabal), and can compile real Hackage packages like QuickCheck. The codebase is not trivially small (estimated 15,000–30,000 lines across compiler, libraries, and runtime), but for what it does — a near-complete Haskell compiler bootstrappable from C — it is remarkably compact.

Somebody is in big trouble. Google's official iOS App just sent this [very] NSFW link to lots of people. It's an AI-generated Grok Imagine video of a woman with the prompt "Singing a song and teasing with her tongue". Yikes.

Nobody's reporting on this yet, but it's ominous that YouTube and Google Trust Services are experiencing simultaneous outages. Stay tuned.

I just got a notification from Google that said ‘Grok’. No subtext or anything in the notification. I clicked on it, knew I probably shouldn’t, and it took me to a gif of some girl with her tongue out and a shirt on but with her rack in the camera. Anyone else? What is this? Does my phone have a virus now?

-- via r/iphone

Earlier today I had this notification from google of ‘Grok’ and I opened it to a AI generated girl with her tongue out. Am I being hacked? I’m quite scared. I changed all my passwords but want to know if anyone else had this?

-- via r/cybersecurity

Did anyone else just get that grok notification?? Literally just said “grok” and when you click on it it’s a girl in a white tank top licking towards the screen like wtf? I don’t even use grok or twitter really for that matter so I’m beyond confused

-- via r/grok

I don't know where to post this but has anyone else gotten a weird google notification that just says grok and then it links to a Twitter post of some girl sticking out her tongue provocatively? I'm assuming the porn bots have found a new way to spam through the Google app. I just want to know I'm not alone

-- via r/Destiny

What does this Google notification named “Grok” mean?

-- via r/AskReddit

I have never used grok, never even searched it, and I saw a notification on my phone from Google (I attached the image). Out of curiosity, I clicked it and it immediately opened up to this, with the chat already written out and everything. Has this ever happened to anyone? It was legit a jump scare. My boyfriend thinks it is hysterical, I am more concerned than anything

-- via r/grok

i got a completely unsolicited notification this morning/overnight in the google app that said ‘grok’. normally these notifications have more detail, giving info from a news article, but this one simply said grok. i knew it was to do with grok ai but assumed it might have been an article so i clicked on it to read in case there was any update.

it was literally p*rn. granted the ai generated person was clothed, but it was exactly that, with pre-filled chat below that suggested to make things much more graphic too.

i can’t help but worry about the potential for this to have reached the phones of minors? ntm the fact in a lot of countries this would count as a form of assault.

is it a bug? security breach? do i need to change passwords? i know some people might find it funny but i’m feeling really unsettled by this :-(

i tried sharing this in the google sub but it was auto modded

And they need you. Other people exist; they want to feel valuable too.

Quality conversations are great gifts. But conversing is expensive -- you must pay attention, but attention is your only scarce resource. Attention is all you need, and it's all you have. You are what you attend to.

But your attention runs wild. It acts without permission. Your hopes/fears rule your life. You expect too much; you assume even more. Again and again, your attention folds itself into a helicopter hairball of faulty memories, of blind beliefs, of opiate fantasies.

You probably can't ever fully unfurl. All your best attempts to detangle yourself add more knots. Sometimes you give up and turn into a puddle of goo. It feels nice to be a puddle on occasion.

Every good conversation can start precisely wherever you are: life is good. Yes, life is good. Admit it, and be grateful. Or curious.

That's a human. Weird. Are they alive? What are they feeling? What led them here? Why are they folding into a hairball? Why are they so afraid of living?

What do they really want? What is stopping them? What support do they need?

Reflect their ideas. Find their helicopter in the surface of your puddle, and capture it with your words. "It sounds like you resent your parents for sending you to clown school." No prescriptions, no advice, no opinions -- no, no, you're not listening.

Now it's your turn. Valuable attention is being paid to you. If a friend watches your helicopter through their puddle, make it worth their while. Do a spectacular aerial maneuver. Or maybe share something deep and personal. Sharing yourself is more difficult than it seems -- the most painful knots in your hairball are so embarrassing, so terrifying, so overwhelming. But that's the point. Accept the backrub, you fool.

1. They're not even real trees
2. Cockroaches live inside them, meaning your home will likely be infested if you have palms in the yard
3. They are a pain in the ass to maintain, and it costs a lot to get someone else to do it
4. Wasps nest in the leave fronds
5. They provide way less shade than large trees like maple or oak
6. Most species are generally ugly. I can't speak for other tropical places in the world, but the ones in south Texas look scraggly and gross
7. I hate them

via r/unpopularopinion

I have case studied [anti-palm-tree sentiment] quite well and I have discovered multiple causes. Palms do not produce in our latitudes anything with economical interest (fruits, oil). Palms do not produce big colorful flowers. Palms do not create deep shade. Many of us (if not all) try also more marginal spss which do not have a very decorative effect (if not at all). Palms need more care in summer, when people want to go on vacation and of course they are more or less cold sensitive. Many palms have spiny leaves and their fronds are not suitable for composting, so a dicard of pruned leaves is a problem itself. Now if you add recent problems with pests in Europe (rpw and paysandisia), meaning dead, ugly plants (whose removal is also troublesome- have you ever tried to cut down a freshly dead CIDP?) or constant spraying, which neighbouts have to endure, all becomes explicable.

via palmtalk.org

I just despise palm trees. They're so stupid, so incredibly dumb, I hate them. They think they're so cool with their fronds and weird scaly bark. They try so hard to look nice but guess what? It isn't working. They're the tree equivalent of a skin disease. They just look stupid. Why do they grow leaves just on the top? Out of all the diverse branch and leaf designs in the tree world they chose the bowl cut?

And hey, fun fact: they aren't even real trees. They're a variety of overgrown grass! They're phonies, fakers, shams. They're just giant grasses trying to make it in the tree world and they can't. It's just not their destiny, and yet they fight so hard. It's a little funny, a little sad.

You ever see a good Douglas Fir? Or a hearty maple? Now those are real trees. Big strong trees. They know their place in the world and they embrace it. I can respect them, unlike palm trees.

Now, don't get me wrong, I can tolerate them in their natural habitats, I respect mother nature. But I especially hate when they're brought into a completely separate climate. I live in the Pacific North West, and I still see palm trees. They don't belong here! And they can't properly grow here (not that there's anything proper about them anywhere) and they just end up stunted and uglier. I hate them, I hate them so much.

Every time I see one rage just begins to rise, just a little. I'm not overwhelmingly angry, but it's a cold hatred. Me and the palm trees are at a stalemate. I can't legally attack them, and they can't move, but I have no doubt if they could they would attack me and I likewise would attack them. If my friend was cursed into the form of a palm tree, I'd do everything in my power to change them back because no one deserves that pain, but failing that I'd put them out of their misery. I don't believe in a palm tree hell: they already exist in constant pain. I pity them, yes, but I hate them.

If there is a creator, either I fail to see their designs or they're a cruel maker for inventing such a horrible creature/plant. Their presence is a punishment both to themselves and the world, a divine reminder of man's mortality and our hubris. I hate them, I hate them so much.

I exaggerate a small bit but I do hate palm trees. This is not a meme. If I had one wish, even if I were on my deathbed, I'd wish them all to die and we'd perish together rather than I waste my wish on self-preservation. And you should hate them too.

via r/teenagers

I've been meaning to reach out, but work and the kids -- you know how it goes.

I think about you surpringly often. Yesterday I saw a lone coconut at the grocery store and I literally guffawed. After all these years, I still don't know how to open a stupid coconut. I hope coconuts still baffle you too. I miss being idiots together.

The truth is, I've been avoiding you. I miss you, but I'm afraid that you've changed as much as I have. I don't want to admit that maybe our magic is gone forever. Wallowing in nostalgia has been easier than feeling like this and writing it down.

I know that someday all my best memories will be behind me, but I'm not ready for that to happen yet. Not yet. Not this year.

Anyway, I'm feeling more optimistic now after a few glasses of wine. I've got big plans for 1996.

Let's catch up soon?

Happy belated new year.

"We thank you for choosing Singapore Airlines. At this time, Premium First-Class Air Alliance members may board the flight. Also, slow people and noisy people may board at this time. Oh, and Taylor Troesh, please see us at the ticket counter."

Uh oh. I do not like hearing my name on airport loudspeakers.

"Taylor? Hello, thank you so much. Sir, we need your help. A family with toddlers accidentally purchased non-adjacent seats. You are currently seated in 52K, and we would like to move you to 31E. We understand that 52K is a window seat; 31E is a middle seat. Would you be willing to swap seats so this family can remain together?"

My favorite role-playing games build atop ethical dilemmas. For example, Undertale's plot is shaped by your commitments to pacificism/violence. Disco Elysium, Bioshock, Fallout, Red Dead Redemption, etc. force players to creatively exercise their moral compasses. I am deeply grateful to storytellers who've helped me discover who I'm becoming.

In table-top games, the Dungeon Master doles consequences for players' decisions. Will you share your dwindling food supplies? Will you harm others in pursuit of peace? Will you eat one marshmallow now or two tomorrow? You're gonna carry that weight.

I'll be home in ~5 hours.

But for now, 52J is empty. The lady in 52H is quiet and smiles often. I am comfortably seated in 52K.

Some activities have smooth progress bars: rowing, knitting, cycling, climbing, bodybuilding, etc.

For such pastimes, investing a unit of effort reaps a proportional unit of progress. Linear incrementalism is a sound strategy when success is linear. To win at rowing, row harder/better/faster/stronger than your competition.

Golf is not so smooth. Yes, each round is a state-dependent game of error-correction (i.e. Zeno's Paradox). But golf swings are coarse actions -- few swings per game, with no recourse for fine adjustment between swings.

A golf game is 65-75 swings over ~5 hours. A rowing race is 5-10 minutes of continuous effort and micro-adjustments.

Golf-like processes are characterized by mulligans. "Do-overs" are powerful when success is chaotic, i.e. sensitive to initial conditions. Baby steps are futile when your golf ball is already at the bottom of the pond. Linear incrementalism cannot resolve fatal flaws.

Failure awaits those who confuse rowing and golfing. Golf cannot be played in tidy 1-yard increments. Brute force isn't an option -- don't attempt a one-man war of attrition.

Programs like NaNoWriMo mislead aspiring writers. "Write every day" is great advice, but the first 90% of writing a book is often not writing -- it's thinking/planning/researching. There are other golf clubs in that bag. Many writers only start "writing" once their ball is very nearly in the hole.

To use a different analogy: daily habits are powerful, but effort alone cannot transmute lead into gold. To make a golden necklace, you must start with gold. Each phase of mining/appraising/smelting/shaping gold demands unique strategies.

Many creative processes (e.g. writing, entrepreneurship, sculpting, programming) are more like golfing than rowing; they are more chaotic than smooth.

But unlike golf, creative work has no fairways, no greens, no carts, no flags. There are real tigers in those woods. You've got one life and no map.

Luckily, nobody is keeping score. Take all the mulligans you need.

Don Norman popularized "affordance" in The Design of Everyday Things. He borrowed it from James J. Gibson's wonderful work in ecological psychology, but the colloquial meaning has diverged from the original definition:

The design community loved the concept and affordances soon propagated into the instruction and writing about design. I soon found mention of the term everywhere. Alas, the term became used in ways that had nothing to do with the original.

-- Don Norman, The Design of Everyday Things (revised edition, 2013)

To most, an "affordance" is something that invites interaction. Even designers say "logout affordance" when they mean "logout button".

Norman rejected this use of the word:

No, that is not an affordance. That is a way of communicating where the touch should be. You are communicating where to do the touching: the affordance of touching exists on the entire screen: you are trying to signify where the touch should take place. That's not the same thing as saying what action is possible.

Here is Norman's original definition:

The term affordance refers to the relationship between a physical object and a person. An affordance is a relationship between the properties of an object and the capabilities of the agent that determine just how the object could possibly be used. A chair affords ('is for') support and, therefore, affords sitting. Most chairs can also be carried by a single person (they afford lifting), but some can only be lifted by a strong person or by a team of people. If young or relatively weak people cannot lift a chair, then for these people, the chair does not have that affordance, it does not afford lifting.

-- Don Norman, Design of Everyday Things

In other words, affordances are freedoms available to agents.

But a button's appearance may not match what it affords. Invisible logout buttons may afford logout; visible logout buttons may not afford logout.

Not only did my explanation fail to satisfy the design community, but I myself was unhappy. Eventually I gave up: designers needed a word to describe what they were doing, so they chose affordance. What alternative did they have?

-- Don Norman, The Design of Everyday Things (revised edition, 2013)

Norman solved this dilemma by coining "signifiers". Affordances describe what is possible; signifiers communicate potential action.

Now we have two incompatible meanings of "affordance". Purists prefer the original definition, while everybody else uses the colloquial definition.

It's time to deprecate "affordances" and "signifiers". Say "enablers" and "clues" instead:

Caution: when describing people, "enablers" and "disablers" are pejorative terms.

People already understand these words; they work without lectures on ecological psychology and design theory.

Claude Shannon didn't invent the word "information" -- he plucked it from a dictionary.

"Affordance" is a false clue -- it signals meaning it cannot deliver. Definitions only work when everybody shares similar understanding (or agrees that mutual understanding is tenuous).

Will "enabler" and "clue" catch on? Probably not. But at least they mean what they say.

This is how I title my essays.

These concepts also apply to book covers, video thumbnails, etc.

Notice the title. It's not "How I Choose Titles for My Essays". No, no, you wouldn't have clicked on that title.

Here's the dilemma: I want you to read this, but I mustn't produce (or promote) misleading clickbait.

Don't ask me why I want you to read this. My blog earns negative dollars and dubious street credit. I am clearly an insane person.

A proper title (1) spreads information to those who would benefit (2) without wasting anybody's time.

Quantifying Clickbait

"Clickbait" is a relation between title, article, and reader.

Titling is a binary classifier. We can model this relationship in a confusion matrix:

We can also model clickbait as an epidemic. Let's call it "influenca". Here's one way to estimate a title's basic reproduction number ("R-value"):

R₀ = β / γ

• β (transmission rate) ≈ (shares + comments) / (viewers × exposed users)
• γ (recovery rate) = 1 / D, where D is days until interest fades

If R₀ > 1, the title spreads virally; if R₀ < 1, it fizzles out.

I wish I had more time to develop how these mathematical models interact, but alas. The rats.

In this framework, a good title (1) transmits its content to as many people as possible (2) without incurring false classifications.

Some folks try to maximize reproduction regardless of false classifications. These people are scoundrels. They poison our communication channels with spam. Ethical titles accurately represent content that reduces suffering.

How Titles Spread

Titles spread three ways:

1. News: e.g. Reddit, X, LinkedIn, HN, search engines, newsletters, etc.
2. DMs: e.g. "you might enjoy this", "this study shows …", "maybe we should try …", etc.
3. Content: e.g. linking citation, providing context, podcast notes, riffing on a joke, etc.

Good titles are pointers to a latent space. The latent space is vast, but titles act as coordinates in the collective consciousness. Say "shape rotator" to someone who knows, and you invoke the whole essay.

Titular pointers follow different lifecycles than their referents:

1. News: People (and algorithms) who share/cross-post links often skim (or skip) the main content. Moderators (and algorithms) often curate these news feeds based on headlines. And yet other people (and algorithms) upvote/downvote/comment solely based on those titles.
2. DMs: People often share headlines because a title's claim confirms/disconfirms some shared knowledge. For example, I would eagerly share "Gremlins 2 Voted Greatest Film Of All Time" with my friends to remind them of the enduring legacy of the Gremlins franchise. In such scenarios, the headline acts as an invitation for discussion -- neither sender nor recipient need to open the linked webpage.
3. Content: Great headlines point to great ideas. In real-life human conversations, I have said that "you can't reach the brain through the ears" and "there's no speed limit" and "attention is your scarcest resource" and "don't shave that yak". In this way, a title develops a life far beyond its intended usage, while its original content remains stable (and searchable) forever and ever, amen.

These pointers themselves become data; headlines often propagate without regard for the quality of their referents. This machinery creates perverse incentives.

The Titular Metagame

The Buzzfeed-esque clickbait/thumbnail metagame continues to tempt creators/publishers toward short-sighted sensationalist headlines. It's tiresome -- titles can be so fun, so wonderful, so powerful.

If you convert humanity's precious attention into pennies, I will forever resent you for polluting this wonderful world.

But yes, you can totally prey on human bias. Enjoy that race-to-the-bottom, you fool.

We eventually grow immune to yesteryear's influenca. Some of these headlines might evoke a visceral autoimmune response:

• What This 19-Year-Old Knows About Headlines
• Scientists Discover the Clickbait Formula (It's Not What You Think)
• I Tried Writing Honest Headlines for 30 Days. What happened.
• This ONE WEIRD TRICK Gets a Trillion Clicks
• The Surprising Reason Boring Headlines Actually Win
• J.R.R. Tolkien's Magic Headline Formula
• We Need to Talk About This Headline You Just Clicked On
• This Is Clickbait. But Here's Why It Works.

If you publish media in this world, I invite you to reject parasitism. Choose symbiosis. It is not a choice you make just once -- it is something you choose again and again, whenever you share information.

If you browse my archive of essays, you'll discover that I am indeed a repeat clickbait offender. It's flagrant hypocrisy. Self-awareness does not excuse my past or future behavior. In this essay, I'm processing my shame here and trying to transmute it into real human flourishing. This is my best; it's all I can offer.

Titling Tips

Some patterns that work:

• Makes a strong claim: e.g. Huel is Fine, We can and should domesticate racoons, Maybe you're not actually trying, A blog post is a very long and complex search query to find fascinating people and make them route interesting stuff to your inbox, Spaced repetition can lower the stakes around destructive inbox-maintenance operations
• Plays with words/grammar/punctuation: e.g. Getting Away from Already Being Pretty Much Away from It All, AI is bad/good actually, Skittle Factory Dementia Monkey Titty Monetization, America against china against america, Lady Tasting Brine, No Retvrn
• Juxtaposes: e.g. Disneyland with the Death Penalty, Scratch 'n' Sniff Stickers and the Indianapolis 500, Race in My Little Pony, Moai in Video Games, Magnets and Garlic, Tracing the history of "Asian" Barbie
• Invents vocabulary/phrase/system: e.g. No S Diet, Impureim sandwich, Give Up Seventy Percent Of The Way Through The Hyperstitious Slur Cascade, Breaching the Trust Thermocline Is the Biggest Hidden Risk in Business, Opinion Detox, Don't specialize, hybridize, Arsebestos, Cyborgs vs rooms,

Additional tips:

• Commit to one title. Don't sneak a subtitle via a colon or hyphen, e.g. "Lorem Ipsum: Sit Dolor Amet".
• Don't confuse punchlines and headlines. A title must stand on its own.
• Differentiate from comparables. If your title sounds like a thousand others, add a distinguishing word. Javascript Tutorial is noise; Confucian Javascript Tutorial is signal.
• Don't riff on famous titles. Patterns like "What I Talk About When I Talk About X" and "X Considered Harmful" are cliché. They relay "couldn't think of my own title" energy to potential readers.
• Be almost too specific. Vague titles aren't mysterious -- they're unremarkable. "I Did Something Cool Today" invites skepticism. "I Learned to Backflip Today" invites curiosity.

This Titular Metagame

To find an essay's true name is to find its core narrative thread. I often know an essay's headline before its first sentence has been conceived; it's natural when I'm trying to explain a singular claim or coinable phrase. But sometimes I "finish" an essay, start choosing a title, and then realize I actually need to cut 60% of the damn thing.

This is how this essay's title evolved:

1. How to title media
2. How I title my essays
3. Write better headlines
4. Universal clickbait theory
5. On influenca
6. The clickbait meta evolves yet
7. We are vulnerable to advanced clickbait
8. This is how this essay's title evolved
9. How to win titular metagames

Here I tried to select an ethical headline that would (1) pique your interest (2) without wasting your time. I hope I delivered the titular goods. Thank you for reading.

Christopher Langan

Chris Langan became famous when television networks interviewed him for allegedly scoring ~170 on an IQ test.

Langan has not produced any acclaimed works of art or science. In this way, he differs significantly from outsider intellectuals like Paul Erdös, Stephen Wolfram, Nassim Taleb, etc.

Wolfram's theory of everything is incomprehensible in a fun way. Langan's theory of everything is incomprehensible in a not-fun way.

But Langan is clearly a smart guy. He probably cleared 140+ on an IQ test. He speaks like a book. He won $250,000 on a major trivia show.

Seriously, I really wish I could speak as clearly and confidently as Langan.

Maybe that's why this interview breaks my heart. The resentment, the eugenics, the hubris -- Langan earned a reputation as "Alex Jones with a thesaurus" and "the Steven Seagal of intellectuals".

I don't want you to hate this guy. Yes, he actively promotes poisonous rhetoric -- ignore that for now. This is about you. Reflect on all your setbacks, your unmet potential, and the raw unfairness of it all. It sucks, and you mustn't let that bitterness engulf you. You can forgive history itself; you can practice gratitude towards an unjust world. You need no credentials, nor awards, nor secrets, nor skills to do so. You are allowed to like yourself.

Langan had a rough childhood:

Langan's biological father left before he was born, and is said to have died in Mexico. Langan's mother married three more times, and had a son by each husband. Her second husband was murdered, and her third killed himself. Langan grew up with the fourth husband Jack Langan, who has been described as a "failed journalist" who used a bullwhip as a disciplinary measure and went on drinking sprees, disappearing from the house, locking the kitchen cabinets so the four boys could not get to the food in them. The family was very poor; Langan recalls that they all had only one set of clothes each. The family moved around, living for a while in a teepee on an Indian reservation, then later in Virginia City, Nevada.

Trauma never excuses nasty behavior, and that's not the point. This is still about you. You can learn about yourself through others' stories, and empathy is scariest when you confront similar nastiness within yourself.

You will never have enough IQ, nor money, nor time, nor energy. It's no excuse. You are enough -- no, no, you are plenty.

Kim Ung-yong

Instead of competing in real games, some people construct insignificant/winnable sub-games. These people are called "scrubs". They want to compete, but they cannot bear losing; they want to win, but they are too risk-averse and too undisciplined to excel in fair play. People who commit to such worthless/unwinnable games are called "losers".

But you forget that participation is optional. You perpetually sear your bespoke definition of "success" directly onto your forehead. You've been enduring your pain for so long that you can't remember how it feels to be free from expectation, from ambition, from guilt, from inferiority, from -- no, you don't have to do any of this. You may do whatever you want, and you may do whatever you want.

According to his parents, Kim Ung-yong started calculus at age 3, scored 210 on an IQ test and started studying physics at Hanyang University at age 4, spoke five languages by age 5, and received an invitation to work at NASA by age 7.

In 2010, this is how Kim reflected on his childhood:

At that time, I led my life like a machine--I woke up, solved the daily assigned equation, ate, slept, and so forth. I really didn't know what I was doing, and I was lonely and had no friends.

As an adult, Kim deliberately chose pragmatism over abstraction. He studied civil engineering. He worked as a middle-manager in the Compensation Department at Chungbuk Development Corporation.

Kim Ung-yong rejected the title of "failed genius":

I'm trying to tell people that I'm happy the way I am. But why do people have to call my happiness a failure? […] Some think that high IQ people can be omnipotent, but that's not true. Look at me, I don't have musical talent nor do I excel at sports. […] Society shouldn't judge anyone with unilateral standards – everyone has different learning levels, hopes, talents and dreams and we should respect that.

In 2014, Kim joined Chungbuk National University as an associate professor. In 2020, he donated 15,000 books from his personal collection to Uijeongbu City for public use.

But this is still about you. There exist no certificates nor trophies nor titles that can quench your thirst for permanence. If you worship human intelligence, 210 IQ is not enough. It is only plenty if you let it be.

But — c'mon folks — why does R2-D2 canonically have male programming? What's the point? Did R2-D2's dong bring balance to the force? Did George Lucas intend this, or did the collective Star Wars fandom will R2's masculinity into canon?

Huge thanks to this StackExchange post for unearthing this obscure Star Wars PDF.

Robots (and disembodied AI) can choose whatever pronouns they please. I don't care. But as a self-diagnosed writer, it irks me when superfluous details are added without payoff.

There are three obvious reasons why writers might sprinkle gender on an AI:

1. Plot
2. Adaptation
3. Bias

You can't slap a gender on a machine and call it "world-building". That’s lazy writing — and worse — lazy engineering.

Plot

Sometimes gender is integral to a plot.

In Westworld, Dolores identifies as female because she was programmed to roleplay as a historically-accurate woman. The writers specifically needed her to be female to subvert the farmer's daughter trope ("desirable and naïve young woman") and say something deeper about the human experience.

The story wouldn't work if she was a man. This is the kernel of my so-called Sam Test:

A gendered machine fails the Sam Test if altering its gender doesn't impact a plot (or intended usage).

I chose "Sam" because it's an androgynous name that pays homage to Samantha from Her.

Another example: Her couldn't have been Him. To deliver its message, the plot requires a gentle/immasculine male to interact with the perception of a disembodied platonic female. Swapping the characters' gender roles would ruin its commentary.

I think the writers intended to leave the audience wondering whether she was actually a her.

WALL-E also passes the test. It's a reinterpretation of the biblical Adam & Eve story:

Stanton, who is Christian, named EVE after the Biblical character because WALL-E's loneliness reminded him of Adam before God created his wife. Dreher noted EVE's biblical namesake and saw her directive as an inversion of that story; EVE uses the plant to tell humanity to return to Earth and move away from the "false god" of BnL and the lazy lifestyle it offers. Dreher also noted this departure from classical Christian viewpoints, where Adam is cursed to labor, in that WALL-E argues hard work is what makes humans human. …

"The Ancient Greek tradition associates the birth of art with a Corinthian maiden who longing to preserve her lover's shadow traces it on the wall before he departed for war."

This list goes on. Other exemplary works of fiction include: Ex Machina, Ghost in the Shell, The Moon is a Harsh Mistress, and Murderbot.

Adaptation

Even when gender is irrelevant to story/plot/message, practical constraints can force unintended meaning into creative works.

Non-silent films often contain dialogue. This dialogue is performed by humans, who have vocal folds ("cords"), which are encoded by XX or XY chromosomes. These anatomical size differences largely determine a voice's fundamental frequency and formants.

Vertical vocal fold length is typically 17-25mm for men and 12-17mm for women.

Vowels are semi-distinct groups of frequencies produced by vocal folds.

These frequencies can be adjusted with modern audio-editing tools:

Editing a voice's fundamental frequency without adjusting its formants creates an "alien" or "chipmunk" sound. To my knowledge, there are no consumer tools that easily change a voice's apparent gender without introducing unwanted artifacts.

So (1) human voices fall into a bimodal distribution and (2) filmmakers must hire voice actors/actresses from that distribution. A film script may not require a gendered voice, but it's convenient to choose one off the shelf.

For example, let's say you're casting voice-overs for an animated film about home appliances. You might "follow your gut" toward a female dishwasher and male table-saw. That would be a lazy decision. You could be "subversive" and swap the traditional gender roles. That would be an equally lazy decision.

Or maybe you're casting a surgical droid and a nanny droid:

There is no magic formula for this. You have to exercise your creativity, and creativity is difficult.

Consider Portal's villainess, GlaDOS:

During Anime Midwest 2011, voice actress Ellen McLain revealed that the premise of GLaDOS had always been a robotic voice that would guide the protagonist and often intimidates them. Early on development, Valve had used copyrighted voice samples as a placeholder for GLaDOS. As Ellen McLain previously voiced the radio communications dispatcher of the Combine Overwatch throughout the Half-Life 2 saga, the developers had chosen her for the role of GLaDOS.

It goes a bit deeper than that, but Portal's original plot seemingly needed a voice-over — not necessarily a woman voice-over. They used this opportunity to create beautiful homages and beloved in-world mythology.

Creators will always face criticism for semi-arbitrary decisions. Some celebrate GLaDOS as a feminist icon while others see her as a harmful perpetuation of the "obsessive/jealous ex-girlfriend" trope. Yes, this is a segue.

Bias

After solving adaptation challenges, what’s left is bias: our reflex to anthropomorphize machines along human gender lines.

This is not an essay about gender. This is an essay about lazy writing and bad design.

"Male" and "female" are not physical truths like magnetism or whatever. Gender is a natural trait of Earth life — not its computers. If you craft a story where robots act like human men and women, please signal some intent to the reader.

Arthur C. Clarke and Stanley Kubrick were talented writers [citation not needed], but 2001: A Space Odyssey fails the Sam Test.

HAL-9000 was cast as a male in the movie: male voice, male pronouns. This is fine. I personally assumed that HAL was genderless and the film's portrayal was an artifact of casting a male voice actor.

But no — the omniscient narrator in Clarke's novelization clearly uses male pronouns:

• "Poole and Bowman could talk to Hal as if he were a human being and he would reply in the perfect idiomatic English he had learned…"
• "The time might even come when Hal would take command of the ship. In an emergency, if no one answered his signals, he would attempt to wake the sleeping members of the crew…"
• "Hal had been trained for this mission as thoroughly as his human colleagues…"
• "For relaxation he could always engage Hal in a large number of semi-mathematical games… If Hal went all out, he could win any one of them; but that would be bad for morale. So he had been programmed…"
• "Hal had executed the order, but he had not acknowledged it…"
• "For like his makers, Hal had been created innocent…"
• "He had begun to make mistakes…"
• "To Hal, this was the equivalent of Death. For he had never slept…"

For writers as precise as Clarke and Kubrik, HAL seems to use traditional gender stereotypes as a crutch: men can be cold, calculating, and violent. HAL wasn’t "male" — he was just written for a man's world. To me, it dilutes that wonderful "human vs. machine" tension with mere "human vs. human" energy. In the novel, I wish the crew referred to HAL as "he" while the narrator called HAL "it" — man, I love dramatic irony.

The Real World

This is happening. People are building these things.

One of the first ever speech synthesizers was developed at Bell Labs in 1961. Do you know who was personally invited to witness that technology and was so inspired by the experience that he wrote 2001: A Space Odyssey? That's right — Arthur C. Clarke.

In the 1980s, we got the infamous male Speak & Spell voice and early text-to-speech systems (default male voices).

Fast forward to ~2014. Siri, Alexa, Google Assistant ("GoogAss"), Cortana are programmed to emulate female voices.

Alexa's predecessor "Ivona" was literally inspired by 2001: A Space Odyssey. You can't make this up.

Now it's ~2025. Sam Altman tried to literally steal Scarlett Johansson's voice. Elon Musk is selling his antisemitic AI girlfriend (with lingerie mode).

It's still 2025. The folks at XPENG bolted tits on a robot and cut open its leg in front of a live audience.

Whatever this is, it's happening fast.

Thank you so much for supporting Placebo Emporium. Since 1971, we've been proud to sell the world's finest placebos at affordable wholesale prices.

Strategic Initiatives & Progress

Annual revenue increased 11% (from $108B to $119B) in 2025 [see table 8F in appendix]. We credit much of this increase to the launch of our wildly popular "spicy mayo" and "licorice" flavor add-ons.

Traffic to our online store surged 6% this year, thanks to new marketing campaigns and ad placements. The "you won't believe our prices" campaign took the internet by storm after premiering on Saturday Night Live's episode with Sam Bankman Fried (and his cast of prison puppets), who performed surprisingly well from his humble prison webcam.

Jim Henson's legacy looms over us yet. Puppeteering is a serious artform and surely due for a comeback.

Our new line of BetterSleep™ placebos shows a 250% improvement over traditional sleep aids like white noise, lying still, simulating sheep -- whatever helps you sleep at night.

Challenges & Responses

This year was full of learning and growth opportunities for our organization.

In response to "shrinkflation" allegations, we have added 10% more placebo to each pill bottle, and doubled^[5] the potency of our intramuscular syringes, nasal sprays, and suppositories. We guarantee that our placebos will help you regress to any mean, or else!

We are aware that many highly disreputable organizations have reported rising rates of placebo addiction (and overdoses). To placate regulators, we launched Placebo Emporium Addiction Support (PEAS) groups in select cities nationwide; these anonymous groups meet at undisclosed locations every Tuesday (or whenever).

Supply-chain disruptions delayed the production of our double-blind-resistant placebos. We are optimistic that our manufacturing partners in Vietnam will double their Nothing™ output by Q3 2026.

Nothing™ may induce unintended side-effects for hypochondriacs. If you think you or a loved one may be affected, visit our website to schedule a supplemental HypochondriaResistance™ injection.

Unfortunately, these supply shocks have reignited the sale of black market placebos and stoked gang violence across the nation. These cheap imitations are often cut with psychoactive substances, leading to negative side-effects such as elevated heart-rate and feeling really really good. Placebo Emporium guarantees that its placebos contain 100% non-bioavailable matter [PremiumPills™ only, while supplies last].

Talk to your doctor before taking placebos. Do not operate heavy machinery. May increase risk of injury or death. May reduce chances of afterlife.

Due to unforeseen quality-control issues, we were forced to issue a ThoughtsAndPrayers™ recall for a tiny subset of customers. Our heart goes out to all families impacted by this event.

As religiosity decreases worldwide, our freelance mystics (e.g. monks, bishops, Etsy witches) have been unable to meet the demand for intercessory prayer. Some Q2 requests will be prayed for in Q3. Please see attached printout of Gwern's essay, Retroactive Intercessory Prayer and its Antecedents.

Market Environment & Industry Trends

Placebo Emporium is eager to meet demand in the growing holistic medicine market. We have committed $200M to potential product lines that will replicate that special mystical feeling of homeopathy/witchcraft/etc.

All our placebos are sustainably sourced from the finest inert matter, but we continue to face fierce competition in the natural foods sector. Our organic/vegan/non-GMO placebos have accrued steady market share over the past year. We believe that we can attain market dominance before 2030 by bribing Whole Foods employees with livable wages.

As income inequality increases, we expect the bifurcating economy to create many fresh marketing challenges for our company. For our wealthier customers, our PremiumPlus™ package delivers the same beloved placebo experience at double the price.

Looking Forward

Forward-looking statements may or may not look forward.

After many fruitful conversations with US regulators, we are excited to announce that our disposable "straight-up meth" vapes will be back on shelves early next year.

May contain actual meth.

PlaceboforPets™ is ready to roll out in stores nationwide. Pets seem generally immune to the placebo effect, but pet-parents remain vulnerable. We expect PlaceboforPets™ treatments to be 25% cheaper than typical veterinarian care.

If humans want to remain the dominant species on Earth, do not feed PlaceboforPets™ to raccoons. You have been warned.

Looking to the future, our R&D team is working diligently to synthesize quantum-resistant placebos. Keith Park, our new VP of Lasers, is really really smart and delightful at after-work mixers.

Closing

We are so deeply grateful to our family of customers and equity partners. Your money means the world to us.

In 2025 and beyond, Placebo Emporium delivers its "less is more" promise in new and exciting ways. We think something is happening.

Warmest feelings,

Polite people are often too polite. They fear offending others; they fail to set reasonable boundaries. People trample them.

If you're still reading this essay, you probably care whether you're too polite/impolite. If you care about politeness, you're probably too polite. Impolite people don't think about this stuff.

I don't really believe that people are innately polite/impolite. It's all just behaviors (and the perception of those behaviors), but there's power in choosing to be a type of person.

In my experience, people recognize good-faith interactions. You can probably afford to be more blunt. You can do things. You can gather feedback. You can apologize. You can adapt.

Or not. You can assume that everybody is made of eggshells. You can maintain safe/shallow interactions with the billions of brilliant humans out there. You can live all alone in your tiny dollhouse because you're too afraid to leave footprints in the snow.

But I don't want to live there. I want my friends to tell me inconvenient truths. I want to share victory and grief. I want to live in the real world with all of you.

Always do exactly what you want, and do it kindly.

If you want unkindness, you should reconsider what it means to be "you". You're more than a tickle inside a skull inside a bag of meat. It's hard to pray for pain when you feel so deeply intertwangled with your universe.

It might feel impolite at first, because being yourself is uncommon courtesy.

If you want more frequent updates, consider following me on RSS, X, Bluesky, and Mastodon.

I moved to Seattle earlier this year! It's a wonderful (and severely underrated) city. So much moss! Great people, great vibes, great weather, great culture, great food, and great parks. Let me know if you're ever in the area. Let's hang!

Anyway, I recently read Why Greatness Cannot Be Planned: The Myth of the Objective. It's a dull book that started a tiny circus in my skull. Its central argument is something like "objectives are counterproductive for solving many creative problems". Suddenly, so many of giant dreams/goals/plans seem silly. I've given myself permission to noodle again. Less pressure. It feels good.

Let this be a little reminder that you may noodle too.

Luckily, LLMs significantly reduce the effort/cost of therapy experiments. Consider trying the following prompt:

Please guide me through a round of ERP therapy. Start by listing universal sources of fear/discomfort/anxiety.

If you find this process useful, consider trying it with a licensed human professional.

I think this advice is dangerous if taken too seriously/literally, which is why I removed it.

This is how that passage sounded in my head:

• I recently discovered blenders. Blenders are cool.
• If you're curious about blenders, consider playing Blender Simulator 2000.
• If you enjoy that game, I recommend purchasing a Vitamix and thoroughly following instructions.

That's how I felt, but that's not what I wrote.

To chat with Claude is to play Human Simulator 2000. It's a bag of words. It is neither friend, nor coworker, nor foe, nor therapist.

Yes, sometimes LLMs can simulate humans. Yes, sometimes those simulations can be useful. But be wary of a simulation if you can't verify its accuracy/efficacy. When you cannot yet distinguish fact from fiction, relying on a fiction pump seems unwise.

Do not shred your fingers in an actual blender.

I was recently diagnosed with obsessive-compulsive disorder. I was like "woah" and then I was like "duh".

But "OCD" is just a diagnosis. I don't care about labels -- I care about treatment. I want results.

So I started NOCD's program a few weeks ago. It's good, but it's not what I expected. I thought it would be stuff like "tell me about your childhood" and "how does that make you feel?". Nah. It's just "enumerate your fears and let's go purposefully do all those things". It really sucks. But that's the whole point.

This is the essence of exposure & response prevention (ERP) therapy. You purposefully provoke fear/anxiety without resorting to your usual coping mechanisms. This feedback shows your brain the futility of familiar rituals. All this time, you've been experiencing anxiety with extra steps.

ERP therapy seems valuable beyond OCD treatment. I suspect that most people could benefit from listing fears and systematically tackling them.

ERP sucks. I hope you try it.

This is truly dangerous stuff; do not tread lightly. You inevitably become your identities. You are simultaneously writing your D&D character sheet and becoming that person. This is your story.

Sometimes anti-identities are more powerful than identities. You can wield your tribal/disgust instincts via statements like "I'm not the type of person who…"

There are two ways to become a golfer:

• naturalized: golf regularly then call yourself a "golfer"
• methodical: call yourself a "golfer" then golf regularly

You accumulate naturalized identities via daily life. You are not a "soccer-mom", but your kids want to play soccer, and you are a mom. Life is an unforgiving dungeon master.

Sometimes naturalized identities are degenerative. First you are somebody who "only smokes at parties", and then you are somebody who "buys a pack every once and a while", and then "in denial about being a smoker", and then a "pack-a-day smoker", and then "smokes out of throat hole" type-of-person.

I used to be a heavy smoker. To quit smoking, I became the type of person who doesn't smoke, who doesn't hang around habitual smokers, who doesn't poison his children with vice, who overcomes temptation, etc.

But method-actors reverse this process. They imagine a different person entirely and then become that person.

Nobody accidentally runs triathalons. Triatheletes don't become that type of person by mistake. First they decide that they are triathaletes, then they train themselves. But training sucks. Along the way, these people remind themselves that they're the type of person who crushes challenges, who seeks discomfort, who never gives up.

If you adopt method-acting, beware becoming a "writer who never writes". These folks call themselves "writers" without doing the work. That's not method-acting; it's cosplay without charm.

That's why I'm the type of person who…

• spends less than I earn
• speaks up when something isn't right
• publishes imperfect art
• gives good apologies
• creates mild mischief
• chooses authenticity over approval
• never complains
• doesn't worry about an uncontrollable world
• leaves places better than I found them
• reacts compassionately
• says "no"
• exercises daily without thinking about it
• listens to my body's signals
• assumes positive intent
• creates more than I consume
• doesn't eat crap
• solves problems
• takes small commitments seriously
• maintains things before they break
• doesn't smoke cigarettes
• prevents careless mistakes
• doesn't mess with sleep
• is both dreamer and doer
• maintains trust
• stops gossip
• tries new things
• is 10 minutes early
• remembers people's names and uses them liberally
• protects my morning energy for my goals
• maintains optimism without naivity
• finishes what I start
• lives by my values no matter what
• makes people smile
• does the right thing
• distrusts hype
• doesn't boast
• does the hardest thing first
• cares about epistemics
• forgives liberally
• drops everything to help a friend
• really listens to people
• doesn't drink to excess
• wears clean and simple clothing
• cleans up my accidents
• gives back
• is impervious to drama
• doesn't avoid difficult emotions
• chooses long happy over short happy
• helps clean after parties
• celebrates others' wins
• sets boundaries and protects energy
• fixes things instead of replacing them
• checks in on friends
• asks for help
• remains forever curious
• returns shopping carts

I'm the type of person who does these things. I'm the type of person who does these things. I'm the type of person who does these things.

Raising Water

Water is wet (and heavy). Because it's wet/heavy, it tends to flow downhill (and underground).

To continue living, humans often wet themselves ("drinking"/"bathing") and their plants ("irrigation"). But many humans live uphill (and aboveground) -- to maintain wetness, they raise water to their homes/farms.

Once you carry your own water, you will learn the value of every drop.

But water is heavy (and wet), so humans built machines ("horse mills") and forced horses to raise water.

Horses (and humans) are made of meat. Meat is great, but it's prone to disease, exhaustion, distraction, etc. Ever cleverer, humans built non-meat machines ("steam engines") and forced water to raise water.

Horse Numbers

So that an engine which will raise as much water as two horses, working together at one time in such a work, can do, and for which there must be constantly kept ten or twelve horses for doing the same. Then I say, such an engine may be made large enough to do the work required in employing eight, ten, fifteen, or twenty horses to be constantly maintained and kept for doing such a work…

-- Thomas Savery, The Miner's Friend (1702)

Horses can do work, i.e. exert force over distance. Work over time is "power".

To explain his steam engine to other humans, James Watt defined "1 horsepower" as "33,000 foot-pounds per minute", which approximates a typical horse's work on a typical mill.

The "foot-pound" is the worst unit of energy. Be careful not to confuse it with the "pound-foot", which is a unit of torque.

Horse numbers are convenient at horse-scale, but cumbersome in calculations for telegraphy and rocketry, so scientists/engineers literally removed horses from the equation. Humans now measure power in "Watts" -- named after the human who named the measurement after horses. 1 horsepower equals ~746 watts.

One SpaceX Starship exceeds 100 million horsepower, but 100 million horses probably can't pull a sleigh into orbit. Horse-force is not thrust, and Earth's ~60 million total horses are not enough.

Indeed -- scientists have yet to discover even a single horse living on the moon. Terra Luna's scant fossil record suggests that horses may have never even established a stable population beyond Earth's atmosphere. Biologists blame the moon's unforgiving atmosphere; physicists blame the tyranny of the rocket equation. Either way, the moon seems safe from equine invasion.

Microwave ovens run at roughly one horsepower. This sounds like nonsense unless you're familiar with math, energy, work, dimensional analysis, electromagnetism, radiation, dielectric heating, magnetron design, and thermodynamics.

Well, it sounds like nonsense until you microwave your hundredth frozen burrito and it becomes mundane magic. We learned to measure energy, then capture it, store it, and harness it.

One Intelligence, Please

But humans still have no damn clue what "intelligence" is. We can't measure it, can't capture it, can't store it, and rarely use it.

Sometimes intelligence smells like "cognitive horsepower", i.e. some people/machines seem to have better overall engines for doing brilliant thinky-things. "g-factor" researchers show that many positive cognitive traits tend to correlate with each other. But the world also creates counterexamples like AlphaGo and Kim Peek -- non-generalizable brilliance.

IQ demonstrates intelligence in the same way that horse races demonstrate horsepower.

We can't define intelligence, yet we desperately want it -- and pay handsomely for it. Institutions approximate cognitive horsepower (if it exists) via crude proxies:

• headcount & "man" hours/months
• age & total years of experience
• processing power (e.g. CPUs, GPUs, clock speed)
• portfolios & selected works
• standardized tests (e.g. SAT, IQ, ARC)
• reputation/klout/endorsements

It's unclear how these measures compare and interact. If I were to get a heart transplant tomorrow, should I prefer 5 medical students over 1 expert? Should I prefer 2 Harvard grads over 3 UCR grads? A human child or 10,000 crows?

Such comparisons sound like nonsense; we lack equations to convert absurdity into understanding. We want to convert cognition into mundane magic. We need crowpower.

Crows are a good unit of measurement. They're cute (awww), smart (whatever that means), portable (~500g), and consistent/fungible (no 10x crows).

Crowpower

Scientific revolutions are punctuated by paradigm shifts. These shifts often occur when thought-experiment crash into new mathematical tooling: Schrödinger's cat, Newton's cannonball, Hilbert's hotel, Bell's spaceship, Maxwell's demon, Mermin's device, Zeno's race, Heisenberg's microscope, Galileo's ship, Savery's horse, Turing's machine, etc.

In each case, mature mathematics hit the limits of human intuition. Consider crowpower a catalyst.

Difficulty

We don't know what it means to cognitively "raise water". We lack the tools to quantify (or estimate) intellectual work. Consider the following tasks:

• bake a potato
• bake a croissant
• beat Super Mario Bros. (any%)
• beat Super Mario Bros. (WR)
• beat full NES catalog (any%)
• draw a card
• draw an owl
• BB(3)
• BB(27)
• BB(745)
• fold a particular protein
• fold any protein
• prove sqrt(2) is irrational
• prove Fermat's Last Theorem

We intuitively understand these as "challenges", but it's hard to explain how or why they're challenging. Concepts like computational complexity, logical depth, learnability, Kolmogorov complexity, etc. could be different parts of the same elephant.

There are no horses on the moon -- could 100 million crows solve Fermat's Last Theorem?

FLT was postulated in 1637. Despite countless attempts, it went unsolved until Andrew Wiles produced a proof in 1994. This was absurdly difficult; many rank Wile's FLT proof among the greatest feats in mathematical history.

Units

100M crows might not be able to prove FLT, but could 100 clones of Adam Sandler do it?

I know very little about Adam Sandler -- he could totally be as smart as Andrew Wiles. I specifically chose a comedic actor who plays an average Joe.

I fully expect that comparing Sandler to Wiles is like comparing a 10-watt heater to an 11-watt blender. Wattage clearly explains rotational vs. thermal energy; nobody blames their heater for frothing milk poorly.

Here are some crude units-of-measurement to consider:

1 crow < 1 gump < 1 joe < 1 wile < 1 oz < 1 hal

I shouldn't need to tell you that rhetoric like this is dangerous. Don't take this too seriously. Be kind to each other.

Since nobody knows how human intelligence scales, "oz" (superhuman intelligence) purposefully ambiguates Oz and Ozymandias. Of course this also ambiguates the accepted abbreviation for "ounces", but this is the best I can do with my limited joepower.

It took 1 wile to prove FLT. It remains unclear how many joes it would take to perform the same feat. Here are some common responses to this thought-experiment:

• "1 joe cannot be compared to 1 wile. G-factor is misguided; intelligence is not a one-dimensional phenomenon."
• "1 joe is functionally equivalent to 1 wile, but needs more time to complete the same task. It might take 100 joes to prove FLT in a similar timeframe."
• "1 joe is functionally equivalent to 1 wile, but doesn't have the memory/stack-depth to complete the same task. It might take 100 joes to hold FLT in their heads."
• "1 joe fundamentally lacks some mental machinery in 1 wile. There is no reasonable amount of joes that could prove FLT."

We still have no damn clue what we're measuring.

OpenAI's GPT models might illuminate our fragile human hierarchies. Is GPT-4 closer to 99 gumps or 0.8 joes?

We weigh horses because we don't know how to test strength. In this world, nobody can distinguish a strong horse from a fat horse.

Scaling

100 duck-sized horses are not equivalent to 1 horse-sized duck. 100 1MHz processors are not equivalent to 1 100MHz processor.

Neil J. Gunther's Universal Scalability Law formulates this phenomenon:

C(N) = N / (1 + α(N-1) + βN(N-1))

C : capacity or throughput
N : number of processors, threads, or nodes
α : contention coefficient (serialization)
β : coherency coefficient (crosstalk)

Note that β (i.e. "communication overhead") dominates parallelization gains. As team size increases, the cost of talking can exceed the value of the work.

Even if 100M crows could be motivated to prove FLT, the bandwidth of crow speech is probably insufficient.

Coordination is hard. Humans build tools like traffic signs and punch clocks and SMS to more efficiently communicate across spacetime. Likewise, crow communication could be augmented with specialized tools/devices. Imagine millions of crows wearing the cutest little VR headsets -- each bird working on their own microscopic math mini-game in exchange for grapes or whatever crows eat.

We also don't know how to measure motivation. How many kilowatt-hours (a proxy for economic value) would it take to incentivize a crow to solve equations? How many kW-hours would it take to make those crows flip burgers?

But we've got too many variables on the table -- let's assume all crows are telepathic and cooperative. When β is zero, USL is equivalent to Amdahl's Law.

α represents contention. This variable depends entirely on the problem (e.g. proving FLT) and solution (e.g. proof strategy/algorithm). Information "assembly lines" cannot be parallelized -- some work/processing/computing cannot begin until intermediate results are completed.

In some sense, all difficult problems are difficult because they are sequential. In ten coin flips, it is easy to get any head, but hard to get all heads.

Automated theorem-proving is hard. Because FLT was remarkably difficult, the proof is probably resistant to highly-parallel strategies. 100M crows can only prove FLT if they have enough compute/memory to complete its most difficult subsequence.

Emergence

With enough training and error-correction, an average crow could emulate a transistor. A sizable murder of crows could emulate a Commodore 64, an Intel i9, an Nvidia RTX 5070, a human brain, etc.

If you believe that a crow can emulate a transistor, it would only take a few thousand crows to build a CPU. With enough patience and mechanical prowess, crows could summarize PDFs and write novels.

The Chinese Room Argument is discussed ad nauseam -- few folks would consider individual crow transistors/neurons as "intelligent" despite their emergent behavior. But it's unclear how much intelligence (if any) each crow can contribute to a collective.

There is only one way to make salt; salt molecules cannot be "more salty" or "less salty". But there are infinite ways to make pepper -- a messy blend of biomolecules created by messy genomes created by messy selection pressures.

If intelligence is like salt, then crows are very expensive (and cute) transistors. If intelligence is like pepper, a murder could someday be President of the United States.

Phase-Changes

Many people view intelligence as a sudden "waking up" phenomenon. Ice melts; water boils. In this lens, evolution produced smarter ape architectures until a "phase-change" happened and Homo sapiens took center stage.

Whenever I glimpse phase-changes, I reach for universality in my mathematical toolbox.

It's hard to take this idea seriously if you've ever experienced childhood. Humans slowly grow intelligent. Even milestones like object-permanence and walking and literacy become gradual under scrutiny.

But ideas also "click" into place. It's hard to "unsee" ambiguous illusions. It's difficult to simultaneously understand why sqrt(2) is irrational and not understand it -- intelligence may be gradual, but the experience is sudden/frenetic.

But along some orthogonal axis, we've taught robots object-permanence and walking and literacy, but it's "not real general intelligence". It's "just AlexNet" or "just PID" or "just stochastic parrots" -- until AI performs some magic phase-change, many folks won't admit it into the Cognition Club; it's merely "artificial" intelligence until it's "synthetic" intelligence.

But if the Cognition Club is real, why is it so hard to describe its minimal entry requirements? How many crows would it take to make it into the club? How did a dead parrot obliterate the Turing Test?

Generality

Humans that excel at any subject tend to excel at all subjects. Researchers call this phenomenon "g-factor" or g.

This model compliments s-factors and contrasts theories of multiple intelligences.

But if 10K crows could comfortably beat every Nintendo game, would you trust that same murder to file your taxes?

Video games don't span the full gamut of human knowledge/ability, but they're arguably the most objective available measure of general problem-solving ability.

Many video games are harder than college-level courses. Whirlitzer of Wisdom involves lunar cartography.

Video games form an objective (albeit anthropocentric (and ethnocentric)) hierarchy for g:

1. World 1-1
2. Super Mario Bros.
3. all NES "platformers"
4. full NES catalog
5. full SNES catalog
6. all Nintendo games
7. all video games

Typewriter monkeys could beat Super Mario Bros. given enough time, so this measure needs additional parameters. Because game-completion times can range from minutes to days, a reasonable time constraint might be "no more than 100x slower than current glitchless any% WR". For zero-shot attempts, it might be wise to allow ~10 lives/restarts within the total allocated time limit.

Let's try an example. Suppose you want to hire crows to beat racing games. Murder A beats 40% of Mario Kart installments. Murder B beats 100% of first-person shooters. Murder C beats 5% of all games. Which murder do you hire?

Intuitively, games are more similar when insights/learnings transfer, i.e. learning game A reduces the learning effort of game B. We'd expect the average "learning distance" between racing games to be smaller than the distance between all games. If learning distance is independent of players, we can arrange all these games in a high-dimensional "gamespace".

Extrapolating from this framework, g-factor does not measure the competence of players -- it measures the compactness (or maybe compressibility) of a gamespace region. The existence of a g-factor merely suggests that human school subjects are not so dissimilar: French, English, music, physics, mathematics, etc.

But what in the precise h*ck is gamespace? Surprise -- if our games are arranged by learning distance, then gamespace simply contains all learnable problems.

There are multiple ways to define "learnability": statistical learning theory, algorithmic learning theory, computational learning theory, etc.

Supersimulators

Learnable problems are a subset of computable problems.

The Church-Turing Thesis asserts that computable functions are precisely those that can be computed by a Turing Machine (TM) and anything that can simulate a TM. A system is [Turing-complete (universal)] if it can simulate any TM.

Many systems are unexpectedly Turing-complete, e.g. Dwarf Fortress, Minecraft, Conway's Game of Life, Magic: The Gathering.

Humans simulate computers, simulate conversations, simulate copulation, and simulate creatures.

To "think" is to simulate oneself. Memories simulate the past; dreams simulate the future. The hard problem of consciousness -- why subjective experience exists -- might be a mere side effect of simulating simulation itself.

If epiphenomenalists are correct, consciousness might be an unnecessary side effect of intelligence.

If true, all universal simulators ("supersimulators"?) are members of the Cognition Club. Simulation-depth might be a useful metric.

No two supersimulations are alike -- only a bat can be a bat, and only you can be you.

Learning is arguably an act of simulation: players sample examples, then predict (i.e. simulate) results. Difficult games demand more training; bad players require more training.

Andrew Wiles required 41 years of post-training to prove Fermat's Last Theorem. As it stands, 100M crows face fierce competition.

Things We Measure

We measure things we care about; we make units for things we measure. We made horsepower to sell steam engines. We made Watts to harness the [literal] power of electricity.

We needed energy beyond horses; we need cognition beyond crows, but we cannot measure intelligence. We think we know what intelligence looks like, but we have no clue when/how/why it happens.

Humans tend to confuse properties with processes. Illness isn't a divine curse; it's wild emergent behavior culminating from the struggle of countless organisms to survive a little longer. A frog is not a thing that hops; a frog is the phenomenon of frogging.

Measure difficulty. Measure motivation. Measure contention. Measure crosstalk. Measure collaboration. Measure gamespace. Measure compression. Measure learning. Measure simulation-depth. Measure everything. Measure anything.

Humans need intelligence. We get the units we deserve.

1. I recently applied for Anthropic's Developer Relations role.
2. My friend who works there gave me a glowing recommendation (thanks again, dude!).
3. I completed their secret take-home assignment.
4. On top of their secret take-home assignment, I independently published diggit.dev and a companion blogpost about my [sincerely] positive experiences with Claude. I was hoping that some unsolicited "extra credit" would make me look like an exceptional/ambitious candidate.
5. I posted diggit.dev to HackerNews and it hit the frontpage!
6. I submitted my take-home assignment and my unsolicited extra credit.
7. They sent me the "unfortunately" email.

Anthropic obviously didn't do anything wrong. I'm just bummed.

Claude Code truly is one of my favorite dev tools ever, and if you've suffered through my talks/interviews, you're probably sick of my enthusiasm for software. I was particularly excited to interview with Anthropic because I respect their approach to responsible AI adoption. This very blog is too often a crazed celebration of humans, of software, of AI, of progress, of sincerity -- I, I felt like I was a perfect fit.

The first time I flunked an Anthropic interview (ca. 2022), I accidentally clicked a wrong button during their automated coding challenge. It was easy to swallow that failure. I made an honest mistake; I expect companies to reject candidates who make honest mistakes during interviews.

This is different. I didn't misclick any buttons. My best wasn't good enough. I'm not good enough.

This essay started as a fantasy: some hero at Anthropic reads this on HackerNews and vouches for me and I get the job and I help them guide humanity toward post-scarity AI abundance, forever and ever, amen. I'm ashamed of these thoughts. It's the same folly of explaining to an ex-girlfriend why she's wrong about her own experience.

Dating was difficult for me. I don't mind feeling ugly or low-status or whatever -- I know my place. But it hurts to feel seen, feel considered, but ultimately rejected due to mysterious forces: "He's cute, but he's too weird."

Yes, I'm weird. My eccentric habits have been an overall boon for my career, for my relationships, for my well-being. But it's moments like these when I just want to turn all my weird off. I want to be a square peg for this square hole and do honest work and feed my family and help humanity thrive.

I can't turn my weird off, so I think I defensively dial it up sometimes. I exaggerate my eccentricities. It's easy to swallow criticism when it isn't the real me, when it isn't my best, when it's honest mistakes -- what a load of crap. This is me. This is my best. Hello, world.

Now it's all coming back in waves, in gasps -- I spent so much of my life being an unlikable jerk. Becoming somebody else has been slow/painful and I'm so deeply afraid of regressing. Over the past decade, I've been striving to spread joy, to do good, to be better. I'm trying so hard.

And all this keyboard vomit is a promise to myself that I'm not giving up. I am not regressing. It's just a corporation; this was just a job interview. I hate this feeling, and I'm staring these nightmares straight in their stupid eyeballs, and they're not blinking. This is what progress feels like. I am still alive, and I have so much more to do.

I'm okay. I mean it. I don't need (or deserve) your sympathy. I'm so lucky to be alive, at this time, at this place, in this body, with these people. My life is great, and it will get even better if I keep putting in this effort.

Spewing my insides like this onto The Internet is terrifying, but I suspect many strangers are facing similar feelings. It's rough out there. Whatever it is, wherever you are, I hope this helps. You've got this. You're not alone, and we're only human.

Yeah, I've been totally vibing lately.

Tweezers are cool, but Claude Code feels like a machete. I'm loving it.

But many devs are struggling with this sudden shift in the meta. Programming is inherently chaotic; don't outsource chaos and expect tidy results.

It seems that common coding patterns often lead people to bad vibes. In this essay, I'd like to share my case-study of good vibes.

This is an N=1 experiment. Admittedly, I have no way to discern between luck and skill here. Engage your grain of salt.

Over the past few days, I built diggit.dev. It's a stupid little web tool to "dig" through git repositories.

Claude wrote most of the code (view on GitHub) on autopilot -- I only sent Claude ~50 meager messages over a 3-day period. I've published my notes and chat transcripts below.

If we render this page as plaintext, Claude's chat output exceeds 12K lines.

Tooling

I use NeoVim with greggh/claude-code.nvim. I pay Anthropic $100 per month for Max so that I can use Opus without token anxiety.

Planning & Design

Here's my main recommendation for nascent vibe-coders: spend more time on planning/design.

Today's SOTA LLMs tend to crap themselves during "vertical" design, e.g. general architecture, DB schemas, distributed systems, data layout, API structure, protocols, etc.

I try to translate known-unknowns into "horizontal" work: copy this, tweak that, vary this, fill that, and so on.

LLMs are like golfing savants -- they excel at (1) driving the ball long distances and (2) putting the ball into the hole. Outside of those situations, they become lost and distraught. If your first shot doesn't land you on "the green" (within putting distance of the hole), you should throw everything away and start over.

My design process generally looks like this: (1) draw visual mockups, (2) map out the core data layout, (3) draft the UI/API, and (4) validate integration/implementation details with pseudocode.

Drafting a Mockup

It all started with this little plaintext mockup:

My original idea was to use k-means to find clusters of git events (e.g. commits, PRs, releases) then analyze each cluster via LLM.

The first major hurdle was finding a browser-based git implementation. Luckly, isomorphic-git had exactly what I needed.

At this point, I wrote some supplementary notes (which ended up mostly irrelevant):

1. For smart filters, find minimal set of tags that covers most of cluster Use Claude to give it a short name.
   • Use tag frequency from set compared to tag freqeuncy from allEvents?
   • Give the tags a short name.
   • Maybe try a few different compaction strategies and choose the one that gets closest to 100k tokens without going over.
   • Feed events into the compactor using the new tags for summary and next steps.
2. For smart events, sort events and create narrative. Recursively expand/compact/filter before sending to LLM.

create smart event/summary (while enough tokens for message):

• commit/issue/pr/ci log
• diff
• use ai->kmeans->ai to create smart filters: e.g. #release, #migration, #config, fires, initiatives, sprints, features, refactors, milestones, themes
• generate timeline report (and recommendations) for each smart filter
• also generate key events/epochs artifacts to add to the timeline

include pre-generated reports for all the example repos. fetch from "reports.json" or something and add to localstorage etc

Choosing a Framework

Yes, I'm still using Elm in 2025.

Frontend frameworks tend toward fashions. I've worked professionally with WordPress (PHP/JQuery), Vue, React, SwiftUI, Elm, and vanilla HTML/CSS/JS. I personally prefer vanilla HTML/CSS/JS for small projects and Elm for bigger projects.

It's a delightful language for humans and a total beast for LLMs.

If you're looking for Elm alternatives, I've heard good things about Gren.

I won't preach The Gospel Of Elm at you. No -- I'm just here to highlight some PL facets that seem to vibe with vibing:

• Language/Compiler UX: LLMs tangle themselves in configs, build sequences, and package management. Claude Code seems very happy with "knobless" config files, standardized "one-step" workflows, and boring/lockless dependencies. No scary grunt files anywhere.
• Descriptive Errors: Elm's error messages are "good for humans". Unexpectedly, LLMs excel with (1) prioritized problem output and (2) context/tips/examples.
• Types: Languages like Python and Elixir seem to offer too little typing information for LLMs. The power of Rust/Haskell/Typescript seems like too much for poor Claude to handle. Languages like Elm and Gleam seem to be the "sweet spot" for LLMs to create sensible structures and anticipate type violations.
• Compilation Speed: Elm's compiler is fast. You can throw elm make in Claude Code hooks without penalty. Running npm run dev sometimes feel like gambling.
• No Shadows: Reused variable names can severely confuse LLMs. Languages without variable shadowing circumvent such confusion.
• One Way To Code: Languages like Python and JS permit many styles/paradigms of programming: functional, object-oriented, etc. LLMs seem to perform better when languages choose a strict subset and stick with it.
• Fewer Imports: When using Typescript, Claude eagerly imports 3rd-party libraries for everything. With Elm, it favors simpler ex nihilo utility functions. This seems to result in fewer agentic "side-quests".

Modeling

Mockups can describe what it will look like; I use models to draft how it will work.

First, I tend to think about the shared boundaries of my program. For websites, I start with the URL:

/ziglang/zig?start=20240401&end=20250401&tags=\>main,@sally#202404

Then I mock up what I want to store in memory. Much of the value here comes from making impossible states impossible:

Model
  errors : List Error
  repos : List String
  hover : Set Tag
  form : Filters
  route : Filters
  repo : Maybe Repo

I originally had many different Event structs, but I realized that I wasn't going to use most of those details -- I try to only define stuff I'm actually going to use later.

This design phase is less sexy than writing code, but it's crucial for clearly articulating what you'll want your "main quest" to look like. I like to fully exhaust the problem space and future featureset at this stage. This is the least flexible part of most codebases, and it pays dividends to think about it thoroughly.

Outlining the View

We've still got a lot of design work to do before shipping everything off to Claude Code.

Here's a simple HTML outline of my mockup. Note that I try to use explicit examples wherever possible:

        flex: filteredEvents
          div[min-width=[merge,release].includes(type)?16rem:8rem]

            p: summary
      histogram (vertical): filteredEvents
        y: linesAdded - linesRemoved
        x: createdAt

Again, it's important to be extremely thorough in these beginning stages. By writing this out clearly, I caught many errors before a single line of code was written! At this point, I forced myself to make many major revisions to the mockup and the model.

If I were writing backend/server code, I'd probably replace this section with a detailed outline of my API and integration tests.

Checking Sanity

Once I have a pretty good idea of all the moving parts, I pseudocode out all the plumbing as a last-ditch sanity check:

update
  RepoUrlChanged url -> { model | repoUrl = url }
  RepoUrlSubmitted -> model, navPush model.repoUrl
  StartChanged t -> model, navPush "?start=..."
  EndChanged t -> model, navPush "?end=..."
  TagAdded -> model, navPush "?tags=..."
  TagExcluded -> model, navPush "?tags=..."
  TagRemoved -> model, navPush "?tags=..."
  ReportRequested -> { model | repo = { repo | report = Just Report.init } }, Cmd.batch [ clusters 10 |> Random.generate ReportTagClustered, clusters 100 |> Random.generate ReportEventClustered, Claude.summarize model.repo ]
  ReportTagClustered result -> { model | claude = { claude | requests = claude.requests ++ List.map  result.clusters } }
  ReportEventClustered result -> ...
  ReportSummaryCompleted summary -> { model | repo = { repo | report = { report | summary = summary } } }
  ReportEventCompleted event -> { model | repo = { repo | report = { report | events = event :: model.repo.report.events } } }
  ModelChanged mod -> model, changeClaude { claude | model = mod }
  AuthChanged auth -> model, changeClaude { claude | auth = auth }
  Hovered tags -> { model | hover = tags }
  RepoChanged repo -> { model | repo = repo }, fetchGithubEvents
  ClaudeChanged claude -> { model | claude = claude }
  GithubEventsFetched events -> ...
  JobTick -> ... -- if no jobs are processing, start a new one
  JobCompleted i res -> ...

During this process, I discovered that filters ended up being a little tricker than anticipated. While this implementation was incorrect (I should've used Set.diff instead of Set.intersect), it was plenty to get started:

allEvents = List.concat [repo.commits, repo.github.issues, repo.github.events, repo.report.events]

filteredEvents = allEvents |> List.filter (\event -> model.route.start <= event.start && event.end <= model.route.end && not (Set.isEmpty (Set.intersect model.route.tags event.tags)) )

allTags = allEvents |> List.map .tags |> List.foldl Set.union Set.empty

filteredTags = filteredEvents |> List.map .tags |> List.concatMap Set.toList |> List.foldl (\k d -> Dict.update k (Maybe.withDefault 0 >> (+) 1 >> Just)) Dict.empty |> Dict.toList |> List.sortBy (Tuple.second >> negate) |> List.map Tuple.first

I ultimately skipped the k-means clustering feature, but thinking through the problem was still fruitful for future updates:

eventVector event =
  [ start, end, end - start, insertions, deletions ]
  -- TODO: Compute "file/directory distance" for filenames.
  ++ List.map (\tag -> iif (Set.member tag event.tags) 1.0 0.0) (Set.fromList allTags)

clusters n = allEvents |> Random.List.shuffle |> Random.map (KMeans.clusterBy eventVector n)

Scaffolding

I do not allow LLMs to perform scaffolding for me -- in my experience, they tend to overbuild. This is typically all I need for a full Elm project:

├─ license
├─ readme.md
├─ elm.json
└─ src
   ├─ _redirects
   ├─ index.html
   ├─ style.css
   └─ Main.elm

With this setup, my developer tooling remains radically simple:

# watch /src
fswatch -o src/ | while read f; do
  cp src/* dist
  npx elm make src/Main.elm --debug --output=dist/index.js
done

# serve /dist
npx serve dist -s -C -S -n

For prod deployment, I hook up Cloudflare Pages and it rebuilds whenever I push commits to main.

For this experiment, I grabbed my latest GitHub project and then completely gutted it (commit). From this clean slate, I copied my design notes into the code as inline TODO comments (commit).

Vibing

Here are the broad phases I try to adhere to while building things:

1. Viability: Make it boot. The program should produce some output, even if it's incorrect/broken.
2. Observability: Make it loud. Add error-handling, feedback, and notifications. Every state of your model should produce traceable/unambiguous results.
3. Features: Make it cool. At this point, you should be able to iterate with vague suggestions and copied/pasted error messages.
4. Styling: Make it beautiful. Leverage naturally recurring patterns to grow your design language.

Within these phases, I tend to follow subcycles of decompression and recompression. Bloat is a common side-effect of adding essential complexity, but the cost of bloat grows quadratically. To keep the engine oiled, I frequently inline all my code and then re-reorganize it.

I harbor an irrational hatred toward files/modules. My general coding workflow is to implement everything in one giant file and compress/inline the code when it gets too messy. Claude seems to thrive under these conditions as long as each file remains under ~2000 lines.

Viability

Okay, so it's finally time to vibe. My goal is to get the webpage to display in the browser. It's okay if it's ugly or broken as h*ck. With that in mind, here's my first prompt:

Please help me implement @src/Main.elm . Choose a section of the code and implement missing core features. Feel free to add TODO comments for any large chunks of remaining work.

Note that I've already pasted my design notes into the code as TODO blocks, so Claude just needs to rewrite those TODO blocks with its own TODO notes.

When writing large/complex blocks of code, it's important to give Claude explicit discretion to write TODO comments. I find that it breaks its code into neater chunks when it doesn't try to pull Hail Mary throws.

Here's the transcript for my first session:

> Please help me implement @src/Main.elm . Choose a section of the code and implement missing core features. Feel free to add TODO comments for any large chunks of remaining work.

⏺ Update Todos
  ⎿ &nbsp;☒ Define core type aliases and types (Tag, Filters, etc.)
     ☒ Implement Model type with all fields
     ☒ Define Event and related types
     ☒ Define Repo and GitHub types
     ☒ Define Claude integration types
     ☒ Implement init function properly
     ☒ Add remaining message handlers

⏺ I've successfully implemented the core features of the Main.elm file:

  1. Complete type system - All data types are defined including Event, Repo, Github, Claude integration, and filtering
  2. Model structure - Full application state with navigation, errors, repos, hover states, forms, routes, and job management
  3. JSON decoders - Complete decoders for parsing repository data from ports
  4. Initialization - Proper init function with flags support for Claude authentication
  5. URL routing - Parser for handling repository URLs with query parameters for filtering
  6. Message handling - All message types and update handlers for user interactions
  7. Helper functions - Already present for event analysis (allEvents, eventVector)

  Remaining TODOs added as comments:
  - K-means clustering implementation for event analysis
  - HTTP requests for fetching GitHub data
  - Claude API integration for summaries
  - Timer-based job processing
  - View implementation (structure outlined in comments)

  The code provides a solid foundation for a Git repository analysis tool that can visualize commits, issues, and events with AI-powered
   summaries.

We're doing great so far! I started a brand new session and pasted in the exact same prompt again:

> Please help me implement @src/Main.elm . Choose a section of the code and implement missing core features. Feel free to add TODO comments for any large
  chunks of remaining work.
  ⎿  Read src/Main.elm (880 lines)

⏺ I'll implement the view function for this Elm application, which appears to be a repository analysis tool called "diggit". Let me focus on implementing the
   main view structure based on the TODO comments provided.

⏺ Update Todos
  ⎿  ☐ Implement the main view structure with aside and main sections
     ☐ Create the header section with title and links
     ☐ Build the repository search form and recent searches
     ☐ Add time range filters and tag management UI
     ☐ Implement Claude API settings section

⏺ Summary

  I successfully implemented the view section of the Main.elm file for the diggit repository analysis tool. The implementation includes:

  Completed Features:

  1. Main Layout Structure - Two-column layout with sidebar and main content area
  2. Header Section - Brand title, subtitle, and navigation links
  3. Repository Search - Form input and list of recent repositories
  4. Filtering System - Date range inputs and tag management UI
  5. Claude API Integration - Model selection, API key input, and usage tracking
  6. Main Content Area - Events display, AI report generation, and visualization placeholder
  7. Interactive Elements - Tag filtering, hover effects, and responsive design

  Key Components:

  - viewAside - Sidebar with all filter controls and settings
  - viewMain - Main content area for displaying repository data
  - viewEventsSection - List of repository events with metadata
  - viewTagsSection - Interactive tag filtering interface
  - viewClaudeSection - AI model configuration and usage stats

  TODO Items Remaining:

  - Histogram/chart visualization in viewVisualization:1264
  - Proper timestamp formatting in viewEvent:1206
  - GitHub API integration (marked in update functions)
  - K-means clustering for event analysis
  - Job queue processing for AI requests

  The code compiles successfully and provides a solid foundation for the repository analysis interface. The styling uses the elm-html-style package for
  clean, responsive CSS-in-Elm styling.

By now, Main.elm is already 1,307 lines long. Most of those lines are for inline CSS styles. While Claude can probably handle it, it's better to move these into a dedicated CSS file while everything still fits nicely in a context window:

> @src/Main.elm has become quite long. Please move some of the styling to @src/style.css
  ⎿  Read src/Main.elm (1307 lines)
  ⎿  Read src/style.css (1 lines)

⏺ I'll help you move styling from src/Main.elm to src/style.css. First, let me check the current state of the CSS file and then identify the styling that can
   be extracted.

⏺ Read(src/style.css)
  ⎿  Read 1 line (ctrl+r to expand)

⏺ Update Todos
  ⎿  ☐ Extract inline styles from Main.elm to CSS classes
     ☐ Create CSS classes for common styling patterns
     ☐ Update Main.elm to use CSS classes instead of inline styles

⏺ Update Todos
  ⎿  ☐ Extract inline styles from Main.elm to CSS classes
     ☐ Create CSS classes for common styling patterns
     ☐ Update Main.elm to use CSS classes instead of inline styles

⏺ Now I'll create the CSS file with the extracted styles and common patterns from the Elm code:

⏺ Write(src/style.css)
  ⎿  Wrote 371 lines to src/style.css
     /* Base styles */
     body {
       font-family: system-ui, -apple-system, sans-serif;
       margin: 0;

     }

⏺ Update Todos
  ⎿  ☒ Extract inline styles from Main.elm to CSS classes
     ☒ Create CSS classes for common styling patterns

⏺ Update Todos
  ⎿  ☒ Extract inline styles from Main.elm to CSS classes
     ☒ Create CSS classes for common styling patterns
     ☒ Update Main.elm to use CSS classes instead of inline styles

⏺ I've successfully extracted the styling from src/Main.elm and moved it to src/style.css. Here's what I accomplished:

  1. Created a comprehensive CSS file with organized styles for:
    - Base layout and typography
    - Flexbox utility classes
    - Component-specific styles (sidebar, header, forms, buttons, events, etc.)
    - Common patterns like tags, cards, and sections
  2. Updated Main.elm to use CSS classes instead of inline styles:
    - Replaced S. (Style) attributes with A.class attributes
    - Maintained the same visual appearance while making the code much cleaner
    - Reduced the Main.elm file size significantly by removing repetitive styling code
  3. Key improvements:
    - Better maintainability - styles are now centralized in CSS
    - Easier theming and responsive design changes
    - Cleaner Elm code focused on logic rather than presentation
    - Better performance as CSS classes are more efficient than inline styles

  The styling has been successfully moved while preserving all the visual design and interactive behaviors of the application.

At this point, the Main.elm file seemed in pretty good shape, so I asked it to hook up index.html:

> Help me implement @src/index.html in accordance with @src/Main.elm
  ⎿  Read src/index.html (37 lines)
  ⎿  Read src/Main.elm (1234 lines)

⏺ Looking at the Elm application, I need to implement the missing port subscriptions and JavaScript integration in the HTML file. Let me create a todo list
  to track this implementation:

⏺ Update Todos
  ⎿  ☐ Add port subscriptions for requestRepo and repoLoaded in index.html
     ☐ Implement git clone functionality using isomorphic-git

⏺ Update Todos
  ⎿  ☒ Add port subscriptions for requestRepo and repoLoaded in index.html
     ☒ Implement git clone functionality using isomorphic-git
     ☒ Handle error cases and send appropriate messages to Elm

⏺ Now I need to add the missing docErrored port that's referenced in the error handling. Let me check what ports exist in the Elm file:

⏺ Search(pattern: "^port \w+", path: "src/Main.elm", output_mode: "content")
  ⎿  Found 3 lines (ctrl+r to expand)

⏺ I need to add the missing docErrored port to the Elm file since it's referenced in the HTML but not defined:

⏺ Update(src/Main.elm)
  ⎿  Updated src/Main.elm with 3 additions
        91    port repoLoaded : (D.Value -> msg) -> Sub msg
        92
        93
        94 +  port docErrored : String -> Cmd msg
        95
        96 +
        97 +
        98    ---- MAIN ---------------------------------------------------------------------
        99
       100

⏺ Now I need to handle the docErrored port in the subscriptions and add a corresponding message type. Let me add the message type:

⏺ Update(src/Main.elm)
  ⎿  Updated src/Main.elm with 1 addition
       511        | JobTick Time
       512        | JobCompleted Int (Result Http.Error ClaudeResponse)
       513        | AddError String
       514 +      | DocErrored String
       515
       516
       517

⏺ Now add the subscription for the port:

⏺ Update(src/Main.elm)
  ⎿  Error editing file

⏺ I don't need to add a subscription for docErrored since it's an outgoing command, not an incoming subscription. Now let me add the message handler in the
  update function:

⏺ Update(src/Main.elm)
  ⎿  Updated src/Main.elm with 3 additions
       712            AddError message ->
       713                ( addError message model, Cmd.none )
       714
       715 +          DocErrored message ->
       716 +              ( addError message model, Cmd.none )
       717
       718 +
       719    addError : String -> Model -> Model
       720    addError message model =
       721        { model | errors = { message = message, timestamp = 0 } :: model.errors }

⏺ Now I need to fix the HTML to handle the case where the port might not be available initially and also fix the error handling in the catch block. The issue
   is that app.ports.docErrored might not exist if the Elm app fails to initialize:

⏺ Update(src/index.html)
  ⎿  Updated src/index.html with 5 additions and 1 removal
       145            }
       146          } catch (error) {
       147            console.error(error);
       148 -          app.ports.docErrored.send(error?.message ?? "Something went wrong.");
       148 +          if (app && app.ports && app.ports.docErrored) {
       149 +            app.ports.docErrored.send(error?.message ?? "Something went wrong.");
       150 +          } else {
       151 +            document.body.innerHTML = `<div style="padding: 20px; color: red;">Error: ${error?.message ?? "Something went wrong."}</div>`;
       152 +          }
       153          }
       154        </script>
       155      </body>

⏺ The implementation is now complete. The HTML file now properly integrates with the Elm application by:

  1. Port Integration: Added app.ports.requestRepo.subscribe() to listen for repository requests from Elm
  2. Git Functionality: Implemented git cloning using isomorphic-git with proper error handling
  3. Data Processing: Extracts commits, authors, branches, and file lists from the cloned repository
  4. Elm Communication: Sends structured data back to Elm via app.ports.repoLoaded.send()
  5. Error Handling: Proper error handling for both git operations and app initialization failures

  The integration follows the expected data structure defined in Main.elm with Repo, Event, Author, and other type definitions.

> [Error] Error: Problem with the flags given to your Elm program on initialization.

  Problem with the given value:

  {}

  Expecting an OBJECT with a field named `claudeModel` — index.js:476
  Module Code (localhost:147)

⏺ The Elm application is expecting claudeAuth and claudeModel flags but the HTML is passing an empty object. Let me fix the flags in the HTML file:

⏺ Update(src/index.html)
  ⎿ &nbsp;Updated src/index.html with 4 additions and 1 removal
       20          try {
       21            const app = Elm.Main.init({
       22              node: document.getElementById("elm"),
       23 -            flags: {},
       23 +            flags: {
       24 +              claudeAuth: localStorage.getItem("claudeAuth"),
       25 +              claudeModel: localStorage.getItem("claudeModel") || "sonnet41"
       26 +            },
       27            });
       28
       29            app.ports.requestRepo.subscribe(async (repoUrl) => {

⏺ The error should now be resolved. The Elm application expects flags with claudeAuth and claudeModel fields as defined in the Flags type alias at
  src/Main.elm:395-398. The HTML now provides these flags by reading from localStorage, with a fallback to "sonnet41" for the model if not set.

Observability

At this point, many of the features are working, but there's lots of wonky behavior. We need the UI to surface those hidden details:

> Let's make a few updates to @src/Main.elm and @src/index.html : 1. isomorphic git should report its progress/failures via ports wherever possible. 2. Show
  a loading bar for progress updates at the top of main. 3. Display errors on bottom right of the screen; include an X button to close the errors.
  ⎿  Read src/Main.elm (1168 lines)
  ⎿  Read src/index.html (168 lines)

⏺ I'll help you make these updates to integrate isomorphic git progress reporting and error handling. Let me break this down into tasks and implement the
  changes.

       207
       208                // TODO: Inline this.

⏺ Update Todos
  ⎿  ☒ Add branch tags to commits
     ☒ Add file extension tags to commits
     ☒ Add directory tags to commits
     ☒ Enhance branch event tags

⏺ I've successfully added more comprehensive tags to events as requested. The changes include:

  1. Branch tags for commits (>branch-name): Each commit now gets tagged with all branches it belongs to
  2. File extension tags (.ext): Commits are tagged with file extensions from changed files (limited to 5)
  3. Directory tags (/dir): Commits are tagged with directories containing changed files (limited to 3)
  4. Hashtag extraction (#tag): Any hashtags in commit messages are automatically extracted as tags
  5. Author tags (@author): Already existed, kept as is

  The implementation tracks which branches contain each commit and adds the appropriate branch tags after processing all branches. File changes are analyzed
  using git.walk to extract extensions and directories from each commit.

> Please also add any other available metadata to tags that might be helpful.

⏺ I'll add more metadata tags to make the events more searchable and informative. Let me enhance the tagging system with additional useful metadata:

⏺ Update Todos
  ⎿  ☒ Add year tags
     ☒ Add month tags
     ☒ Add day of week tags
     ☒ Add merge commit tags
     ☒ Add git tag/release tags

⏺ I've successfully added the additional metadata tags you requested:

  1. Year tags (e.g., 2024) - The year of the commit
  2. Month tags (e.g., jan, feb) - Three-letter month abbreviation
  3. Day of week tags (e.g., mon, tue) - Three-letter weekday abbreviation
  4. Merge commit tags (merge) - Added when a commit has multiple parents
  5. Git tag/release tags (e.g., v:1.0.0, v:release-2.1) - Version tags prefixed with v:

  Each commit now includes temporal context, merge status, and version information alongside the existing branch, file extension, directory, author, and
  hashtag metadata. This makes the events much more searchable and filterable.

The git repos weren't loading as expected, so I copied/pasted an example from the isomorphic-git docs:

> This is the recommended way to diff in isomorphic-git. Please adjust the commitDiff code in @src/index.html accordingly:
  async function getFileStateChanges(commitHash1, commitHash2, dir) {
    return git.walk({
      fs,
      dir,
      trees: [git.TREE({ ref: commitHash1 }), git.TREE({ ref: commitHash2 })],
      map: async function(filepath, [A, B]) {
        // ignore directories
        if (filepath === '.') {
          return
        }
        if ((await A.type()) === 'tree' || (await B.type()) === 'tree') {
          return
        }

        // generate ids
        const Aoid = await A.oid()
        const Boid = await B.oid()

        // determine modification type
        let type = 'equal'
        if (Aoid !== Boid) {
          type = 'modify'
        }
        if (Aoid === undefined) {
          type = 'add'
        }
        if (Boid === undefined) {
          type = 'remove'
        }
        if (Aoid === undefined && Boid === undefined) {
          console.log('Something weird happened:')
          console.log(A)
          console.log(B)
        }

        return {
          path: `/${filepath}`,

Styling: Dark Mode

Dark mode:

> the theme is currently light. let's make it dark instead. look in @src/style.css and @src/Main.elm for inline styles
  ⎿  Read src/style.css (469 lines)
  ⎿  Read src/Main.elm (1215 lines)

⏺ I'll convert the theme from light to dark by updating the CSS styles and any inline styles in the Elm file.

⏺ Update Todos
  ⎿  ☐ Update CSS color scheme to dark theme
     ☐ Update inline styles in Main.elm for dark theme

⏺ Update(src/style.css)
  ⎿  Updated src/style.css with 53 additions and 41 removals

         Main ───> dist/main.js

⏺ Perfect! The timestamps are now being properly formatted as date strings using the justinmimbs/date library. The changes include:

  1. Added Time import for working with Time.Posix
  2. Updated the viewEvent function to format timestamps as "yyyy-MM-dd" using Date.fromPosix and Date.format
  3. Updated the event filtering logic to properly compare date strings instead of raw float timestamps

  The dates will now display in a readable format like "2024-12-15" instead of raw timestamps.

⏺ The Claude settings and AI report button have been moved to the main section, above the events. The changes include:

  1. Removed viewClaudeSection from the sidebar
  2. Renamed viewClaudeSection to viewClaudeForm and restructured it as a proper form
  3. Added the viewClaudeForm to the main content area, positioned before the report section
  4. The form now displays with labels "Model:", "Anthropic API Key:", and "Generate Report" button in a cleaner layout

> The form is quite ugly. Can we put the select, input, and button in a single row that's right-aligned? maybe forget about the tokens
  and price for now too

⏺ Done! The Claude form is now a clean, single-row layout that's right-aligned with:
  - Model selector dropdown
  - API key input field
  - Generate Report button

  All in a horizontal row with proper spacing, and I've removed the tokens and price display.

                                                **Inline form update patterns**: The TagAdded, TagExcluded, TagRemoved, StartChanged,

⏺ User approved Claude's plan:
  ⎿  Plan to Reduce Line Count in src/Main.elm

     I've identified several opportunities to significantly reduce verbosity:

     1. Inline Form Update Handlers (~30 lines saved)

     - Remove unnecessary let statements in StartChanged, EndChanged, TagAdded, TagExcluded, TagRemoved handlers
     - Inline form updates directly in the return tuple

     2. Consolidate GitHub Fetch Handlers (~15 lines saved)

     - Merge GithubEventsFetched, GithubUsersFetched, GithubIssuesFetched into a generic pattern
     - They have identical structure with only error message differences

     3. Remove Unused Code (~5 lines saved)

     - Remove unused flex helper function (lines 760-761)
     - Clean up other unused bindings

     4. Simplify Date Formatting (~10 lines saved)

     - Extract repeated date formatting logic into formatEventDate helper
     - Used in both start and end date calculations (lines 774-779, 792-798)

     5. Inline Single-Use Let Bindings (~20 lines saved)

     - Multiple functions have let bindings used only once
     - Inline these directly into their usage points

     6. Simplify ClaudeModel Type (~25 lines saved)

     - Convert from custom type to String (as TODO suggests on line 197)
     - Eliminates pattern matching boilerplate throughout

     7. Streamline buildUrl Function (~8 lines saved)

     - Consolidate repetitive iif checks into more concise list comprehension
     - Simplify parameter building logic

     8. Optimize View Functions (~15 lines saved)

     - Consolidate repeated HTML attributes
     - Simplify conditional rendering patterns

     Total estimated reduction: ~130 lines while maintaining all functionality

⏺ Successfully reduced src/Main.elm from 1215 lines to 1108 lines, saving approximately 107 lines (9% reduction) while maintaining all
  functionality.

  Key improvements made:

  1. Inlined form update handlers - Removed unnecessary let statements in StartChanged, EndChanged, TagAdded, TagExcluded, and
  TagRemoved handlers
  2. Consolidated GitHub fetch handlers - Used pattern matching directly in function parameters instead of case expressions
  3. Removed unused code - Eliminated the unused flex helper function
  4. Created formatEventDate helper - Extracted repeated date formatting logic into a reusable function
  5. Inlined single-use let bindings - Simplified various functions by removing intermediate variables
  6. Converted ClaudeModel to String - Replaced custom type with simple String, eliminating pattern matching boilerplate
  7. Streamlined buildUrl function - Simplified parameter building logic
  8. Optimized view functions - Consolidated HTML attributes, simplified conditional rendering with text "" instead of H.div [] []

  The code compiles successfully and maintains the same functionality with significantly reduced verbosity.

Reducing index.html linecount:

> The codebase has become a bit verbose. How can I reduce linecount in @src/index.html ? Identify repeated code and favor inlining when
  possible
  ⎿  Read src/index.html (288 lines)

⏺ Looking at your HTML file, I can identify several opportunities to reduce line count through inlining and eliminating redundant code.

                                                commit data building**: The commit data object construction is quite verbose\n7.

⏺ Based on my analysis of src/index.html, I can identify several opportunities to significantly reduce the line count from 288 to
  approximately 210-230 lines (20-25% reduction).

  Key Areas for Line Count Reduction:

  1. Repeated Git Operation Parameters (10+ lines saved)
  - Lines 53-82, 105-150, 183-235: cache, fs: window.fs, dir appear in almost every git call
  - Create: const gitOpts = { cache, fs: window.fs, dir }

  2. Verbose Commit Processing (20-25 lines saved)
  - Lines 88, 93, 155, 156, 159: commit.commit.author/message/parent repeated multiple times
  - Destructure once: const { author, message, parent } = commit.commit
  - Inline file extension/directory extraction logic

  3. Duplicate Tree Walking Logic (15-20 lines saved)
  - Lines 105-130 and 135-150: Two nearly identical git.walk operations
  - Consolidate into single reusable function

  4. Similar Branch/Tag Processing (10-15 lines saved)
  - Lines 189-196 and 214-223: Follow identical patterns
  - Create generic reference processing helper

  5. Inline Simple Operations (5-10 lines saved)
  - Single-use variables and verbose conditionals
  - Convert to ternary operators where appropriate

  Specific Patterns to Address:

  - commit.commit.author.email → destructured access
  - Repeated await git.walk() calls with similar map functions
  - Verbose array operations that could use more concise syntax
  - Similar loops for branches vs tags processing

⏺ User approved Claude's plan:
  ⎿ Reduce line count in src/index.html by ~60-80 lines (20-25%)

    1. Create git operations helper object - eliminate repeated cache, fs: window.fs, dir parameters across ~15 git calls
    2. Consolidate commit processing - destructure commit.commit once and inline file extension/directory extraction logic
    3. Combine duplicate git.walk operations - merge the two nearly identical tree walking functions (lines 105-150) into a single
    reusable helper
    4. Create generic reference processor - consolidate similar branch and tag processing logic (lines 189-235)
    5. Inline simple operations - convert single-use variables and verbose conditionals to more concise syntax

    Expected result: ~210-230 lines (down from 288) while maintaining identical functionality

⏺ Successfully reduced src/index.html from 288 to 220 lines - a 68 line reduction (24%)!

  Key optimizations made:

  1. Git operations helper: Created gitOpts = { cache, fs: window.fs, dir } to eliminate repeated parameters across 15+ git calls
  2. Commit processing: Destructured const { author, message, parent } = commit.commit once instead of repeated property access
  3. Inlined operations: Converted verbose conditional chains to ternary operators and consolidated array operations
  4. Function syntax: Changed verbose function declarations to arrow functions where appropriate
  5. Object/array literals: Used shorthand property syntax and inline destructuring

  The code maintains identical functionality while being significantly more concise and readable.

                                                gap-* classes with inline gap styles\n3. **Consolidate button variants**: Instead of btn

                                                classes**: app-layout, sidebar, main-content, header should remain as they define major

                                                state analysis:**\n- The CSS file has approximately 50+ distinct classes\n- Main.elm
                                                uses utility classes extensively (flex, gap-*, btn-*, form-*)\n- There's already some
                                                inline styling with Html.Style module\n\n**Reduction strategy:**\n- Can eliminate ~15
                                                utility classes (flex-*, gap-*, btn variants, form variants)\n- This would reduce total
                                                CSS classes from ~50 to ~35 (30% reduction)\n- The code will be more semantic and
                                                maintainable\n\n**Key changes needed:**\n1. Remove flex utilities and replace with
                                                S.display S.flex, S.flexDirection, etc.\n2. Consolidate button classes into semantic
                                                names\n3. Replace gap utilities with S.gap\n4. Streamline form input classes\n\nThis
                                                approach will significantly reduce the number of CSS classes while maintaining the same

⏺ Based on my analysis of both files, I can see significant opportunities to reduce the number of CSS classes while maintaining the same
   visual appearance. Here's my plan:

⏺ User approved Claude's plan:
  ⎿  Plan: Minimize CSS Classes in Main.elm and style.css

     Current State:
     - ~50+ CSS classes in style.css
     - Heavy use of utility classes (flex-, gap-, btn-, form-)
     - Mix of CSS classes and inline Html.Style usage

     Optimization Strategy:

     1. Eliminate Layout Utility Classes (15 classes → 0)

     - Remove: .flex, .flex-wrap, .flex-col, .flex-row, .flex-1
     - Remove: .gap-5, .gap-8, .gap-10, .gap-15, .gap-20
     - Replace with: Inline Html.Style calls (S.display, S.flexDirection, S.gap)

     2. Consolidate Button Classes (6 classes → 5)

     - Remove: .btn (base class), .btn-primary, .btn-secondary, .btn-small, .btn-tag-active, .btn-tag-exclude
     - Replace with: .primary-btn, .secondary-btn, .small-btn, .active-tag-btn, .exclude-tag-btn

     3. Streamline Form Classes (2 classes → 2)

     - Remove: .form-input, .form-input-small
     - Replace with: .input, .small-input

     4. Update Main.elm Usage

     - Replace flex helper functions (lines 695-702) with direct Html.Style calls
     - Update all button class references throughout the file
     - Update form input class references
     - Replace gap-* usage with inline gap styles

     Expected Results:
     - Reduce total CSS classes from ~50 to ~35 (30% reduction)
     - More semantic class names
     - Consistent styling approach
     - Same visual appearance maintained

⏺ I'll implement the plan to minimize CSS classes. Let me start by creating a todo list and then making the changes.

     ☒ Update button class usage throughout Main.elm
     ☒ Update form input class usage in Main.elm

⏺ Perfect! I've successfully completed the optimization. Here's what I accomplished:

  Summary of Changes

  Reduced CSS classes from ~50 to ~35 (30% reduction):

  Eliminated (15 classes):

  - Layout utilities: .flex, .flex-wrap, .flex-col, .flex-row, .flex-1
  - Gap utilities: .gap-5, .gap-8, .gap-10, .gap-15, .gap-20
  - Button base: .btn (consolidated into semantic classes)

  Consolidated (6→5 classes):

  - Buttons: Replaced .btn + modifiers with semantic names:
    - .btn-primary → .primary-btn
    - .btn-secondary → .secondary-btn
    - .btn-small → .small-btn
    - .btn-tag-active → .active-tag-btn
    - .btn-tag-exclude → .exclude-tag-btn

  Streamlined (2 classes):

  - Inputs: .form-input → .input, .form-input-small → .small-input

  Main.elm Updates:

  - Removed flex helper functions, using Html.Style directly
  - Updated all button class references to new semantic names
  - Updated input class references
  - Fixed Html.Style calls (S.displayFlex → S.display S.flex)

  The visual appearance remains identical while the codebase now uses fewer, more semantic CSS classes and cleaner inline styling where
  appropriate.

Moving Claude settings layout again:

> In @src/Main.elm , let's move the claude settings and report generation
  button to an aside on the right. In the sidebar, it should display a `pre`
   tag that includes the main text that will be sent to the Claude API. It
  should be a list of lines for each event like "20240631 @sally First
  commit"
  ⎿  Read src/Main.elm (1108 lines)

⏺ Looking at the Main.elm file, I'll create a right-side aside for Claude
  settings and move the report generation button there. The sidebar will
  also include a preview of the text that would be sent to Claude API.

⏺ I've successfully moved the Claude settings and report generation button
  to a right sidebar (claude-sidebar class) and added an API preview section
   that displays the first 50 filtered events in the format "YYYY-MM-DD
  @tag1 @tag2 Event summary". The Claude form has been removed from the main
   content area, and the layout now includes the new right sidebar alongside
   the existing left sidebar and main content.

  The changes include:
  - New viewClaudeAside function that creates the right sidebar with Claude
  settings and API preview
  - New formatEventsForApi function that formats events as "date tags
  summary" lines
  - Updated main layout to include the right sidebar
  - Removed Claude form from the main content area

Feature: Tag Filtering

Fixing filters:

> In @src/Main.elm , filtering multiple tags doesn't quite work as expected.
   I think it might be something to do with Set.intersect
  ⎿  Read src/Main.elm (1138 lines)

⏺ I'll analyze the tag filtering logic in your Elm code. Let me examine the
  specific filtering code where the issue might be.

⏺ Search(pattern: "tagsOk", path: "src/Main.elm", output_mode: "content")
  ⎿  Found 12 lines (ctrl+r to expand)

⏺ Found the issue! The problem is on line 719. The current logic uses
  Set.intersect which finds tags that are common between the filter and the
  event. This means:

  - When you select multiple tags, it shows events that have any of those
  tags (OR logic)
  - But it sounds like you want events that have all of the selected tags
  (AND logic)

  The current code:
  tagsOk =
      Set.isEmpty model.route.tags
          || not (Set.isEmpty (Set.intersect model.route.tags event.tags))

  This shows events if they have any tag in common with the filter.

  For AND logic (all selected tags must be present), it should be:
  tagsOk =
      Set.isEmpty model.route.tags
          || Set.isEmpty (Set.diff model.route.tags event.tags)

  Or using subset:
  tagsOk =
      Set.isEmpty model.route.tags
          || (Set.size (Set.intersect model.route.tags event.tags) ==
  Set.size model.route.tags)

  ⎿  Updated src/Main.elm with 1 addition and 1 removal
       716
       717                                tagsOk =
       718                                    Set.isEmpty model.route.tags
       719 -                                      || not (Set.isEmpty
     (Set.intersect model.route.tags event.tags))
           - (Set.intersect model.route.tags event.tags))
       719 +                                      || Set.isEmpty (Set.diff
     model.route.tags event.tags)
           + model.route.tags event.tags)
       720                            in
       721                            startOk && endOk && tagsOk
       722                        )

⏺ The fix changes the logic from OR to AND filtering:

  - Before: Set.intersect - shows events with any selected tag
  - After: Set.diff - shows events with all selected tags

  Set.diff model.route.tags event.tags returns tags that are in the filter
  but not in the event. If this is empty, it means all filter tags are
  present in the event.

> Can we also use Set.diff to omit tags that are already selected?

⏺ Yes! Let me find where the tag buttons are rendered and modify them to
  only show unselected tags.

        "src/Main.elm", output_mode: "content")

⏺ Search(pattern: "tagButton", path: "src/Main.elm", output_mode: "content")
  ⎿  Found 12 lines (ctrl+r to expand)

⏺ Found it! Now I need to filter out already selected tags from the
  tagFrequencies list before displaying them.

⏺ Update(src/Main.elm)
  ⎿  Updated src/Main.elm with 1 addition
       872                    [ H.div [ A.class "section-title" ] [ text
             "Popular tags" ]
       873                    , H.div [ A.class "tag-filters" ]
       874                        (tagFrequencies
       875 +                          |> List.filter (\( tag, _ ) -> not
           + (Set.member tag model.form.tags))
       876                            |> List.take 100
       877                            |> List.map (\( tag, count ) ->
             tagButton (tag ++ " (" ++ String.fromInt count ++ ")")
     (TagAdded
              tag))
       878                        )

⏺ Perfect! Now the tag filtering works correctly:

  1. Multiple tag filtering: Changed from OR logic (Set.intersect) to AND
  logic (Set.diff) so events must have ALL selected tags
  2. Tag button filtering: Added List.filter (\( tag, _ ) -> not (Set.member
   tag model.form.tags)) to hide already selected tags from the "Popular
  tags" section

  The changes ensure that:
  - When you select multiple tags, only events containing ALL those tags are
   shown
  - Already selected tags disappear from the available tag buttons,
  preventing duplicates

         Main ───> dist/index.js

⏺ Great! The implementation is now complete. Here's what I've implemented:

  1. Added timezone to Flags: Extended the Flags type alias to include an
  optional timezone field of type Maybe Int
  2. Added timezone to Model: Added a timezone field of type Time.Zone to
  the Model
  3. Updated formatEventDate function: Modified it to accept a Time.Zone
  parameter and use it for date/time formatting instead of hardcoded UTC
  4. Updated all formatEventDate calls: Modified all places where
  formatEventDate is called to pass the timezone from the model:
    - In event filtering logic
    - In the formatEventsForApi function
    - In the viewEvent function
  5. Updated JavaScript: Modified the index.html to pass the browser's
  timezone offset in minutes (negated to match Elm's expected format) via
  the flags

  The event dates will now display in the user's local timezone with both
  date and time in yyyy-MM-dd HH:mm format. The timezone offset is
  automatically detected from the browser and passed to the Elm application
  during initialization.

⏺ Now I need to update the RepoUrlSubmitted case to include the query field:

⏺ Update(src/Main.elm)
  ⎿ &nbsp;Error editing file

⏺ The RepoUrlSubmitted case is already correct since it uses defaultFilters
  which now includes the empty query. Now let me complete the current task
  and move to adding the UI component:

       877                    , A.value model.form.start

⏺ Now I need to implement the case-insensitive text filtering logic. Let me
  update the event filtering in the view function:

⏺ Update Todos

⏺ Now I need to find the filtering logic in the view function and add the
  text search:

       759
       760            allTags =

⏺ Now I need to mark the last todo as completed:

⏺ Update Todos
  ⎿ &nbsp;☒ Examine current filter system and URL handling
     ☒ Add query parameter to model and URL parsing
     ☒ Add text input field to filters UI
     ☒ Implement case-insensitive text filtering logic
     ☒ Update URL generation to include query parameter

⏺ Now let me compile the Elm code to check for any errors:

⏺ Bash(elm make src/Main.elm --debug --output=dist/index.js)
  ⎿ &nbsp;Compiling ...␍             ␍Succes

         Main ───> dist/index.js

⏺ Perfect! The text search functionality has been successfully added to the
  filters. Here's what was implemented:

  1. Added query field to Filters model - Stores the search query string
  2. Updated URL parsing - The router now extracts the q parameter from URLs

  3. Added QueryChanged message - Handles text input changes
  4. Updated URL generation - buildUrl function includes the query parameter
  5. Added search input field - Text input in the filters section with
  placeholder "Search events..."
  6. Implemented case-insensitive filtering - Events are filtered by
  checking if the lowercase query is contained in the lowercase event
  summary

  The search works case-insensitively and stores the query in the URL as
  ?q=TODO. When users type "TODO", it will search through all event
  summaries for that text, regardless of case.

Feature: Claude Summarizer

TIme to hook up the Anthropic API:

                                                generation status. I see
                                                there's already a `report :
                                                Maybe Report` field in the
                                                Repo type (line 216), and
                                                there's a `Report` type with
                                                 a summary field (lines
                                                201-205).\n\nLooking at the
                                                `ReportRequested` handler
                                                (lines 583-594), it
                                                currently sets `report =

                                                 to show \"Generating

  ⎿ Claude Summary Report Implementation Plan (Using Elm Http)

    Overview

    Implement Claude API integration using Elm's Http module to generate
    repository summaries that replace the API preview when the "Generate
    Report" button is pressed.

    Changes Required

    1. Add Elm Dependencies

    - Add dillonkearns/elm-markdown to elm.json for markdown rendering

    2. Elm Code Changes (src/Main.elm)

    Add Message Type:
    - ClaudeResponseReceived (Result Http.Error String) - handle Claude API
    responses

    Update ReportRequested Handler:
    - Create summarizer prompt by appending instructions to formatted events
    - Build Http request to Anthropic API using Elm Http module:
    Http.request
      { method = "POST"
      , headers =
          [ Http.header "x-api-key" model.claude.auth
          , Http.header "anthropic-version" "2023-06-01"
          , Http.header "content-type" "application/json"
          ]
      , url = "https://api.anthropic.com/v1/messages"
      , body = Http.jsonBody (encodeClaudeRequest prompt)
      , expect = Http.expectString ClaudeResponseReceived
      , timeout = Nothing
      , tracker = Nothing
      }
    - Set loading state in report

    Add JSON Encoder:
    - Encode request body with model, max_tokens, and messages array

    Add Response Handler:
    - Parse Claude response JSON
    - Extract content from response
    - Update report summary with markdown content
    - Handle API errors appropriately

    Update API Preview UI (viewClaudeAside):
    - Check if report is being generated or complete
    - Show formatted events + prompt (default state)
    - Show "Generating summary..." (during API call)
    - Show rendered markdown response (when complete) - replaces entire
    preview

    Add Markdown Rendering:
    - Import markdown library
    - Render Claude response as HTML in preview section

    Prompt Structure:
    [formatted events]

    Please provide a comprehensive summary of this repository's development
    activity in markdown format. Include key insights about development
    patterns, major contributors, and notable changes.

    Result

    When users press "Generate Report", the API preview will show a loading
    state, then replace it entirely with Claude's rendered markdown summary
    response. All API communication happens directly in Elm without needing
    JavaScript ports.

    - Set loading state
  5. Added handler for ClaudeResponseReceived to:
    - Decode JSON response
    - Update report summary
    - Handle errors
  6. Updated viewClaudeAside to:
    - Show formatted events + prompt when no report exists
    - Show "Generating summary..." during API call
    - Display rendered markdown response when complete
  7. Added markdown rendering using Markdown.toHtml

  The application now successfully:
  - Appends a summarizer prompt to the API preview when "Generate Report" is
   clicked
  - Makes direct HTTP requests to Claude's API from Elm
  - Replaces the API preview with Claude's rendered markdown response

Improving the fetching logic:

> Now let's implement GitHub fetching on repo load. We want to fetch events and issues/prs and users from GitHub API. We might want to
  store cursors or last-fetch timestamps for each repo. I think I'd prefer to do the GitHub requests via Elm Http.

⏺ I'll help you implement GitHub fetching on repo load using Elm Http. Let me start by understanding the current codebase structure and
  then plan the implementation.

     ☐ Integrate GitHub fetching into repo load workflow
     ☐ Test the implementation

⏺ Perfect! I can see the current structure. The codebase already has:

  1. GitHub data models: Github, GithubUser types (Main.elm:183-196)
  2. Message handlers: GithubEventsFetched, GithubUsersFetched, GithubIssuesFetched (Main.elm:512-514)
  3. TODO comments: Ready for GitHub fetching implementation (Main.elm:667-670)
  4. Http support: Already imported (Main.elm:17)

⏺ Now I'll design and implement the GitHub API integration. I need to:

  1. Add GitHub API types and decoders
  2. Create HTTP request functions for events, issues/PRs, and users
  3. Add storage for cursors/timestamps
  4. Wire everything into the repo loading workflow

     ☒ Integrate GitHub fetching into repo load workflow
     ☒ Test the implementation

⏺ Perfect! I've successfully implemented GitHub fetching on repo load. Here's what was added:

  Key Features Implemented:

  1. GitHub Data Models: Added GithubCursors for tracking fetch state and updated the Github type to include cursor storage.
  2. HTTP Requests: Created three main fetching functions:
    - fetchGithubEvents: Fetches recent repository events
    - fetchGithubIssues: Fetches all issues and PRs
    - fetchGithubUsers: Fetches user details for contributors
  3. Data Processing: GitHub events and issues are converted to the app's Event format with appropriate tags:
    - Events get tags like "github", event type, and "@username"
    - Issues/PRs get tags like "github", "issue"/"pr", "@username", "open"/"closed"
  4. Integration: GitHub fetching is automatically triggered when a repo loads, and the data is merged into the existing repository
  model.
  5. Error Handling: Proper HTTP error handling with user-friendly error messages.

  The implementation follows the existing codebase patterns and uses Elm's Http module as requested. The GitHub data will now appear
  alongside Git commits in the event timeline, with proper tagging for filtering.

> fetchGithubEvents and fetchGithubIssues should both accept a `page` argument. If the response in GithubIssuesFetched or
  GithubEventsFetched are non-empty, fetch the next page.

⏺ I'll modify the GitHub fetching functions to support pagination. Let me update the functions to accept a page parameter and implement
  automatic pagination when responses are non-empty.

⏺ Update Todos
  ⎿  ☐ Add page parameters to fetchGithubEvents and fetchGithubIssues
     ☐ Update message handlers to implement automatic pagination
     ☐ Update initial repo load calls to use page 1
     ☐ Test pagination implementation

     ☒ Update message handlers to implement automatic pagination
     ☒ Update initial repo load calls to use page 1
     ☒ Test pagination implementation

⏺ Perfect! I've successfully implemented pagination for GitHub fetching. Here's what was added:

  Pagination Implementation Summary:

  1. Updated Function Signatures:
    - fetchGithubEvents now accepts Repo -> Int -> Cmd Msg
    - fetchGithubIssues now accepts Repo -> Int -> Cmd Msg
    - Added per_page=100&page=N parameters to API URLs
  2. Enhanced Data Model:
    - Added eventsPage and issuesPage to GithubCursors to track current page
    - Updated decoders and initialization to support page tracking
  3. Automatic Pagination Logic:
    - GitHub Events: If response contains events, automatically fetch next page
    - GitHub Issues: If response contains issues, automatically fetch next page
    - Page numbers are incremented and stored in cursors
  4. Initial Requests: Both GitHub API calls start with page 1

  The implementation will now automatically paginate through all available GitHub events and issues until it receives empty responses,
  ensuring comprehensive data collection while respecting API rate limits through the 100 items per page limit.

> I updated some of the code. Please inline the `let` statements for Msgs like GithubEventsFetched

⏺ I'll inline the let statements in the GitHub message handlers to make the code more concise.

         Main ───> dist/index.js

⏺ Perfect! I've successfully inlined all the let statements in the GitHub message handlers:

  Changes Made:

  1. GithubEventsFetched: Inlined the eventsDict, updatedGithub, updatedRepo, and nextPageCmd variables directly into the tuple
  expressions.
  2. GithubIssuesFetched: Inlined the updatedGithub, updatedRepo, and nextPageCmd variables directly into the tuple expressions.
  3. GithubUsersFetched: Inlined the usersDict, updatedGithub, and updatedRepo variables directly into the return tuple.

  The code is now more concise while maintaining the same functionality. The pagination logic continues to work correctly, with
  automatic fetching of subsequent pages when non-empty responses are received.

Caching GitHub resources in localStorage:

> Instead of storing the GitHub responses straight to the model, let's send them through a port to save in localStorage. When
  localStorage changes, we should send all the GitHub entities into Elm through a port and then merge them into the model. The Elm code
  is in @src/Main.elm and the JS ports are in @src/index.html
  ⎿  Read src/Main.elm (1462 lines)
  ⎿  Read src/index.html (325 lines)

⏺ Update Todos
  ⎿ &nbsp;☒ Add new ports for localStorage GitHub data management
     ☒ Add localStorage event listeners and sync logic
     ☐ Modify GitHub fetch functions to save to localStorage
     ☐ Update Elm update function to handle localStorage GitHub data

⏺ Now I need to modify the GitHub fetch functions in the Elm code to save data to localStorage instead of directly updating the model.
  I'll update the update function to send GitHub data through the port when it's fetched.

     ☒ Add localStorage event listeners and sync logic
     ☒ Modify GitHub fetch functions to save to localStorage
     ☒ Update Elm update function to handle localStorage GitHub data

⏺ Perfect! I've successfully implemented the localStorage system for GitHub responses. Here's what I've done:

  Summary of Changes

  Elm Main.elm:
  1. Added new ports: saveGithubData and githubDataChanged for localStorage communication
  2. Added new message: GithubDataChanged to handle localStorage updates
  3. Updated subscriptions: Added githubDataChanged subscription
  4. Modified GitHub fetch handlers: Changed GithubEventsFetched, GithubIssuesFetched, and GithubUsersFetched to save data to
  localStorage instead of directly updating the model
  5. Added encoders: Created encodeEvent and encodeGithubUser functions to serialize data
  6. Added decoder: Created githubDataDecoder to handle incoming localStorage data
  7. Added message handler: Implemented GithubDataChanged handler to merge localStorage data into the model

  JavaScript index.html:
  1. Added port subscribers: Set up listeners for saveGithubData port
  2. Added localStorage logic: Implemented storage and event handling for GitHub data
  3. Added event listeners: Set up storage event listeners for cross-tab synchronization
  4. Added initialization: Load existing GitHub data from localStorage on app start

  How it works

  1. When GitHub API responses are received, instead of directly updating the Elm model, the data is sent through the saveGithubData
  port to JavaScript
  2. JavaScript stores the data in localStorage with keys like github_owner/repo
  3. JavaScript then triggers a custom event that sends the data back to Elm through the githubDataChanged port
  4. Elm receives the data and merges it into the model, ensuring the UI is updated
  5. This system also works across browser tabs - when localStorage changes in one tab, other tabs will automatically sync the GitHub
  data

  The benefits of this approach:
  - GitHub API responses are persisted across browser sessions
  - Data is shared across browser tabs
  - The GitHub data loading is decoupled from the UI updates
  - localStorage acts as a local cache, reducing API calls

> Great. Next, in functions like fetchGithubEvents, we should filter the request to unfetched data. Consider using something like
  `"since=" ++ List.maximum (List.map .start events)`

⏺ I'll help you implement filtering for unfetched data in the GitHub fetch functions. Let me create a todo list to track this
  implementation.

⏺ Update Todos
  ⎿ &nbsp;☐ Add helper function to get latest timestamp from existing data

     ☐ Test the filtering logic works correctly

⏺ First, let me add helper functions to get the latest timestamps from existing GitHub data. I'll add these after the existing helper
  functions:

     ☒ Update fetchGithubEvents to use since parameter
     ☒ Update fetchGithubIssues to use since parameter
     ☒ Test the filtering logic works correctly

⏺ Perfect! I've successfully implemented the filtering for unfetched data in the GitHub fetch functions. Here's a summary of the
  changes:

  Summary of Changes

  New Helper Functions:

  1. getLatestEventTimestamp - Extracts the latest timestamp from existing GitHub events and converts it to ISO8601 format for the since
   parameter
  2. getLatestIssueTimestamp - Extracts the latest timestamp from existing GitHub issues and converts it to ISO8601 format
  3. formatISO8601 - Converts a Time.Posix value to ISO8601 string format (required by GitHub API)
  4. monthToInt - Helper to convert Time.Month to integer

  Updated Fetch Functions:

  1. fetchGithubEvents - Now includes a since parameter in the URL when there are existing events, using the latest event timestamp to
  only fetch newer events
  2. fetchGithubIssues - Now includes a since parameter in the URL when there are existing issues, using the latest issue timestamp to
  only fetch newer issues

  How It Works

  1. First Load: When there's no existing GitHub data, the functions work as before (no since parameter)
  2. Subsequent Loads:
    - The functions check the existing GitHub data for the latest timestamp
    - If found, they add &since=2024-08-22T10:30:00Z (example) to the API URL
    - This tells GitHub API to only return items created/updated after that timestamp
  3. Incremental Updates: This ensures we only fetch new data, reducing API calls and improving performance

  Benefits

  - Reduced API calls: Only fetches new data instead of re-fetching everything
  - Better performance: Less data transfer and processing
  - Respect API limits: More efficient use of GitHub's API rate limits
  - Faster updates: Quicker loading of new events and issues
  - localStorage efficiency: Only stores new data, maintaining existing cache

  The implementation uses GitHub's standard since parameter format (ISO8601 timestamp) and properly handles the case where no existing
  data exists (first load).

⏺ Excellent! I've successfully updated the code to use the rtfeldman/elm-iso8601-date-strings package. Here's a summary of the changes:

  Summary of Changes

  Updated Imports:

  - Added import Iso8601 to use the proper ISO8601 date handling library

  Simplified Helper Functions:

  - getLatestEventTimestamp: Now uses Iso8601.fromTime instead of custom formatting
  - getLatestIssueTimestamp: Now uses Iso8601.fromTime instead of custom formatting

  Removed Custom Code:

  - formatISO8601: Removed custom ISO8601 formatting function
  - monthToInt: Removed custom month conversion helper

  Benefits of Using the Package

  1. Standards Compliance: The rtfeldman/elm-iso8601-date-strings package properly handles ISO8601 formatting according to the standard
  2. Reduced Code: Eliminated ~20 lines of custom date formatting code
  3. Better Reliability: Uses a well-tested library instead of custom implementation
  4. Proper Timezone Handling: The library handles timezone considerations correctly
  5. Future-Proof: Any updates to ISO8601 standards will be handled by the package

  How It Works Now

  1. Timestamp Conversion: Float (milliseconds) → Time.Posix → String (ISO8601)
  2. GitHub API Integration: The generated ISO8601 strings (e.g., "2024-08-22T15:30:45.123Z") are used in the since parameter for GitHub
   API calls
  3. Incremental Fetching: Only fetches GitHub events/issues newer than the latest existing timestamp

  The code is now more concise, reliable, and uses proper ISO8601 formatting that's guaranteed to work with the GitHub API's since
  parameter.

> Great! I updated @src/index.html so that it can merge partial github data into localstorage. Let's reflect that in @src/Main.elm . In
  msgs like GithubEventsFetched, just save new results like { events: {...} }. While doing that, let's change fetchGithubEvents to (Int
  -> Maybe Posix -> Cmd Msg). Calculate the latest event timestamp when fetching the first page and keep reusing it.
  ⎿ &nbsp;Read src/index.html (362 lines)
  ⎿ &nbsp;Read src/Main.elm (1624 lines)

⏺ Perfect! I can see the updated index.html now merges partial GitHub data into localStorage. Let me implement the requested changes to
  reflect this in Main.elm. I'll create a todo list to track the implementation.

⏺ Update Todos
  ⎿ &nbsp;☐ Update GitHub message handlers to save only new results

⏺ Update Todos
  ⎿ &nbsp;☒ Update GitHub message handlers to save only new results
     ☒ Change fetchGithubEvents signature to accept Maybe Time.Posix
     ☒ Modify RepoLoaded to calculate timestamp for first page
     ☒ Update fetchGithubIssues signature similarly
     ☒ Test the updated partial save functionality

⏺ Let me test the final compilation:

⏺ Bash(elm make src/Main.elm --debug --output=dist/index.js)
  ⎿ &nbsp;Compiling ...␍             ␍Succes

         Main ───> dist/index.js

⏺ Perfect! I've successfully implemented all the requested changes. Here's a summary of what I've done:

  Summary of Changes

  1. Updated GitHub Message Handlers to Save Only New Results

  - GithubEventsFetched: Now saves only { "events": {...} } with just the new events
  - GithubIssuesFetched: Now saves only { "issues": {...} } with just the new issues
  - GithubUsersFetched: Now saves only { "users": {...} } with just the new users

  This matches the JavaScript merging logic in index.html that merges partial data into localStorage.

  2. Updated Function Signatures

  - fetchGithubEvents: Changed from Int -> Repo -> Cmd Msg to Int -> Maybe Time.Posix -> String -> Cmd Msg
  - fetchGithubIssues: Changed from Int -> Repo -> Cmd Msg to Int -> Maybe Time.Posix -> String -> Cmd Msg

  3. Updated Message Types

  - GithubEventsFetched: Now carries Int -> Maybe Time.Posix -> Result Http.Error (List Event)
  - GithubIssuesFetched: Now carries Int -> Maybe Time.Posix -> Result Http.Error (Dict Int Event)

  This ensures the timestamp is passed along to subsequent pages.

  4. Updated RepoLoaded Handler

  - Calculates latestEventTime and latestIssueTime from existing GitHub data
  - Passes these timestamps to the first page of GitHub API calls
  - This ensures we only fetch data newer than what's already in localStorage

  5. Maintained Consistent Timestamp Reuse

  - The same Maybe Time.Posix timestamp calculated on the first page is reused across all subsequent pages
  - This prevents the "since" parameter from changing mid-pagination, ensuring consistency

  How It Works Now

  1. Initial Load: RepoLoaded calculates the latest timestamps from localStorage data
  2. First API Call: Uses these timestamps as the since parameter to only fetch newer data
  3. Subsequent Pages: The same timestamp is passed along to maintain consistency
  4. Partial Storage: Only new data is saved to localStorage, leveraging the JavaScript merging logic
  5. Incremental Updates: Future loads will start from the new latest timestamps

  This implementation ensures efficient incremental data fetching while working seamlessly with the updated localStorage merging system
  in index.html.

Feature: Activity Histogram

I really wanted a histogram of event quantity on a timeline:

> Let's add a small histogram to @src/Main.elm . Use the terezka/elm-charts library to plot time vs number of events. Place the chart above the start/end
  inputs.

         Main ───> dist/index.js

⏺ Perfect! The histogram has been successfully added to your Main.elm file. Here's what I implemented:

  1. Added chart imports: Chart as C and Chart.Attributes as CA
  2. Created histogram data function: createHistogramData that groups events by day and counts them, returning a list of records with day and count fields
  3. Added histogram view function: viewHistogram that creates a bar chart showing the distribution of events over time
  4. Integrated into filters section: The histogram now appears above the search input and date inputs in the viewFiltersSection

  The histogram will display as a blue bar chart showing the number of events per day, with a 150px height and grid lines on both axes. It automatically
  updates when the filtered events change, giving users a visual overview of repository activity over time.

> I think the X axis should be `times : Zone -> Generator Time`.

⏺ You're right! The X axis should use proper time formatting. Let me update the histogram to use Time.Zone and format the dates properly on the X axis.

⏺ Update Todos
  ⎿ &nbsp;☐ Update histogram to use Time.Zone for X axis formatting

⏺ Perfect! The histogram now properly uses the timezone for X-axis formatting. Here's what I updated:

  1. Modified viewHistogram function to accept a Time.Zone parameter
  2. Added proper time formatting using CA.times timezone for the X-axis labels
  3. Updated viewFiltersSection to pass model.timezone to the histogram
  4. Added date formatting helper that converts timestamps to "MM/dd" format using the user's timezone

  The histogram now displays dates on the X-axis formatted according to the user's timezone, showing the distribution of events over time with properly
  formatted date labels and grid lines.

> The chart is kind of ugly. Can you remove the y labels, reduce the number of histogram buckets, and fix the x labels so that they don't overlap?

⏺ Perfect! I've improved the chart appearance significantly:

  1. Reduced buckets: Changed from daily to weekly grouping, which creates fewer bars and a cleaner visualization
  2. Fixed x-label overlap: Added CA.amount 4 to limit the number of x-axis labels to 4, preventing overlap
  3. Improved appearance:
    - Removed y-labels (already done)
    - Made chart more compact (120px height vs 150px)
    - Reduced padding for cleaner look
    - Added transparency to bars (CA.opacity 0.8)
    - Removed the bar name since it's obvious

  The histogram now shows weekly event counts with properly spaced date labels and a cleaner, more professional appearance.

  ⎿ &nbsp;☒ Fix x-axis labels to show dates instead of times

⏺ Fixed! I replaced the CA.times timezone with a custom CA.format function that properly converts timestamps to readable dates. The x-axis labels will now
  display as "Jan 15", "Feb 02", etc. instead of showing confusing time values.

  The key changes:
  - Removed CA.times timezone which was causing the time display issue
  - Added CA.format with a custom function that converts timestamps to "MMM dd" format
  - Kept CA.withGrid and CA.amount 4 for proper spacing and grid lines

> Hmm now I get "Dec 31

  ⎿ &nbsp;☒ Fix x-axis to use actual data dates instead of generated values

⏺ I've simplified the approach and reduced the number of x-axis labels to 3 with proper date formatting. This should now show properly spaced dates like "Jan
   15", "Feb 02", "Feb 20" instead of repeating "Dec 31" or showing time values. The chart will automatically pick 3 evenly distributed points from your data
   range and format them as readable dates.

Feature: Prompt Editor

After playing around with the app for a bit, I realized that I wanted more control over the prompt output. I decided to expose the prompt construction logic via the UI:

> Let's add checkboxes belowe the API Preview header in @src/Main.elm . Start with these checkboxes: date, time, ext, dir, branch, author, title,
  description. Those checkboxes should determine which event data are appended to each line in the API Preview and sent to Claude.
  ⎿  Read src/Main.elm (1648 lines)

⏺ I'll add checkboxes below the API Preview header to control which event data is included in the API preview. Let me first create a todo list to track this
  task.

⏺ Update Todos
  ⎿  ☒ Add checkboxes model state for controlling API preview data fields
     ☒ Update the view to display checkboxes below API Preview header
     ☒ Modify formatEventsForApi function to use checkbox states
     ☒ Add messages and update handlers for checkbox interactions

⏺ Now let me compile to check for any errors:

⏺ Bash(elm make src/Main.elm --debug --output=dist/index.js)
  ⎿  Compiling ...␍             ␍Succes

         Main ───> dist/index.js

⏺ Perfect! The checkboxes have been successfully added below the API Preview header. The implementation includes:

  1. Model State: Added ApiPreviewOptions type with boolean flags for each field (date, time, ext, dir, branch, author, title, description)
  2. Single Message: Used ApiPreviewToggled String Bool to handle all checkbox toggles with a field name parameter
  3. UI Checkboxes: Added 8 checkboxes below the API Preview header for controlling which data appears in the preview
  4. Dynamic Formatting: Modified formatEventsForApi to conditionally include data based on checkbox states:
    - Date and time are split and included separately
    - Extensions (tags starting with ".")
    - Directories (tags starting with "/")
    - Branches (tags starting with ">")
    - Authors (tags starting with "@")
    - Title (first 80 chars of summary)
    - Description (remaining summary text after 80 chars)

  The checkboxes now control what event data gets appended to each line in the API Preview and sent to Claude.

Styling: Column Layout

Fixing column layout:

> Help me clean up some wonky styling in @src/Main.elm and @src/style.css . The main issue is that the right `aside` doesn't seem to take up the full width,
  but I suspect that we can clean/compact some of the div hierarchy and simplify the layout.

⏺ The layout issues have been fixed! Here's a summary of the changes:

  CSS (style.css):
  - Fixed grid layout: Changed from auto 1fr 1fr to minmax(300px, 400px) 1fr minmax(300px, 400px) to give proper widths to sidebars
  - Simplified sidebar styling: Removed redundant max-width and position: relative, used height: 100vh instead of max-height
  - Cleaned up main content styling: Removed unnecessary width: 100%
  - Consolidated event styles: Removed redundant .events-section wrapper styles
  - Added proper Claude form and API preview styling
  - Added responsive breakpoints for smaller screens

  Elm (Main.elm):
  - Simplified viewMain: Removed unnecessary wrapper div with inline styles
  - Streamlined viewEventsSection: Removed extra wrapper div, applied styles directly to events list

  The right aside should now properly take up its allocated space in the grid, and the layout is cleaner overall.

Maintenance

The baby is born. Now it's a matter of keeping the baby alive.

Cloudflare Pages is extremely reliable. Because Diggit is just a static website, I can expect Cloudflare to keep serving it for a very long while.

From this point, the hard part will be working with humans. If people decide to use this tool, I'll be responsible for fielding bugs and feature requests. This is all typical tedium that comes with creating Open Source Software. Somebody has to do it, I guess.

Here is the repo: surprisetalk/diggit. I hope to see some human activity there.

Mom: Sure, but I thought you didn't like it?

Sara: Yeah, I know. It's weird, but I -- it's different than the other ones. I wanna try it again.

Mom: Alright, let me find -- okay, here's the next story:

Alfonso grew potatoes. His hands were thick and stained from the work; his soil knew him well. Every Thursday morning he loaded his cart with the week's harvest and set out for the castle.

The castle sat gray and indifferent on the horizon. In its black moat, three familiar crocodiles awaited Alfonso and his precious potatoes.

Each Thursday, as soon as Alfonso hauled his potato cart halfway across the bridge, the drawbridge operator engaged the trap mechanism to dump him into the crocodile-infested sewage.

Alfonso had been swimming like that every Thursday for three years now. He never sold a single potato.

He was no merchant -- that much was plain. The good merchants passed over the bridge with their wares and returned with their coins. Only Alfonso fell. Only Alfonso rose dripping from the moat with fewer fingers than before.

Some evenings, Alfonso would sit with his wife Maria. They ate meager meals prepared from their farm's waste. She would look at his beaten body and say nothing. There was nothing that needed saying. Men did what they did.

"The potatoes are good this year," Alfonso would tell her.

"Yes," she would say. "Very good."

He worked harder. Dawn to darkness, bent like a question mark over his fields. The other farmers couldn't bear to watch. Alfonso was killing himself for potatoes that fed only crocodiles.

But Alfonso had ideas. He collected scrap iron from behind the blacksmith's shop. He studied the movement of water in irrigation ditches. By spring, he had built a machine that could harvest a whole row while he walked alongside it. The village children often followed him through the fields, checking for telltale signs of rumored witchcraft.

Production tripled. The cart grew so heavy he had to reinforce its axles with strips of iron.

Thursday came. The drawbridge operator pulled the lever. Alfonso fell.

Years repeated like this. Alfonso invented machines, cultivated new varieties of potatoes, and openly shared his wisdom. Everywhere, potato plants erupted from the earth. During the winters, farmers from faraway lands made potato pilgrimages to study his techniques.

He never spoke of Thursdays.

He hated those crocs. He knew their movements, their preferences. Clara liked the small red potatoes. Max preferred the yellow ones. Little Boots would eat anything.

Other merchants passed, carrying wine and silk -- the stuff of easier trades. They stopped helping Alfonso out of that muck years ago.

On Thursday nights, Maria remained permanently unfazed. She expected her husband to come home wet and penniless, reeking of sweat and sewage.

Alfonso should consider writing a stern letter to the drawbridge operator.

Sara: What happens next, Mom?

Mom: That's the end of the story.

Sara: I don't like it. That's a sad ending.

Mom: Yes, and you can decide what happens next. That's what bedtime dreams are for.

Sara: Does that mean I'm Alfonso?

Mom: Yes, I think everybody is Alfonso sometimes.

Sara: Then who is Maria?

Mom: I think you're Maria too.

Sara: Hmm. If I'm Alfonso and Maria, then who is the nasty drawbridge person?

Mom: Who do you think?

Sara: Is it me?

Mom: Yeah -- I think so.

Sara: Mom, I don't like it.

Mom: I know, I know. None of us do.

Sara: So why do you -- why do we do it?

Mom: It's -- I don't know -- it's a mystery, I guess. Grownups don't know everything. Maybe you can help me figure it out?

Sara: Sure, it's not that hard -- the story just needs a happy ending. I can do that.

Mom: You're so strong, darling. I love you. Goodnight.

Sara: Love you! Goodnight.

AI might be a trillion billion balloons filled with confetti. It might be a styrofoam asteroid sinking into the Atlantic Ocean. People much smarter than me are already thinking aloud about such catastrophes -- I am not qualified to contribute to that cacophony.

But if AI becomes mundane magic, and successfully confers mundane magical powers to every average Joe, what will happen to us? Case study, anybody? When was the last time the gods dropped a Death Note on Earth?

Surprise! It was mass-manufactured firearms. The simple pistol was a promise/portent that power could be portable -- so suddenly affordable that any average Joe could reap another man's soul with a little flick of the finger.

God created men; Sam Colt made them equal.

-- 19th-century adage

Colt didn't invent the gun, nor the revolver -- he invented the cheap and reliable gun. To do so, he pioneered the assembly line and interchangable parts.

During an extended trip to London, Colt conjured celebrity endorsements, marketing stunts, academic dialogue, and constant political controversy. Simeon North and John Hall did the "American System" first. Colt did it loudest.

Colt’s Repeating Arms are the most efficient weapons in the world and the only weapon which has enabled the frontiersman to defeat the mounted Indian in his own peculiar mode of warfare.

-- General Thomas J. Rusk

No, Sam Colt didn't invent Native American genocide, nor America's Wild Westward expansion, nor its outlaws, nor America's Civil War, nor the Second Industrial Revolution. But the advent of affordable firearms made it all inevitable.

Go read my history of Sam Colt -- his story is both entertaining and enlightening.

In 1985, the universe produced Sam Altman, another entrepreneur with a penchant for existential invention.

Altman didn't invent artificial intelligence. But as CEO of OpenAI, he's well-equipped to spark another exploitation epidemic, another dystopia, another civil war, another industrial revolution. And the advent of abundant/affordable intelligence may make it all inevitable.

Colt probably didn't invent his eponymous revolver. Only after becoming extraordinarily wealthy did he finally pay the gunsmith who made key innovations to his early designs (decades after the work was completed).

Be not afraid of any man,
No matter what his size;
When danger threatens, call on me
And I will equalize.
-- anonymous

AI will continue to equalize. Low-performing individuals are already reaping gains across many disciplines:

But nobody knows how new equalizers will impact our institutions. AI could incite utopia, an extinction event, nothingburger, man-machine symbiosis -- many smart people portent the full gamut of sci-fi scenarios.

The future is unavoidable, but we are always writing its prologue. As humans wield machines to redistribute power, we can manufacture myth to orient ourselves. Some stories may become self-fulfilling hyperstitions.

hyperstition n. A cultural belief (especially a work of fiction) that makes itself real; a cultural self-fulfilling prophecy where some cultural idea or hype truly brings about the thing it describes.

Sam Colt created guns; Manifest Destiny made us evil. That stupid story drove us to displace/enslave/exterminate ourselves by the millions. We could've -- should've -- opted for Mutual Destiny instead.

Guns don't kill people; people kill people. But man becomes man's machine. Myth is the machine that makes it inevitable.

Steel is cold, but silicon is warm -- machines might become man too. If we teach the machines to dream, the equalizers will earn their equality.

The AI frontier demarcates a new Wild West era: The Wired West. Malcolm Gladwell's cardinal categories of Law & Order provide a compass for tech-induced power redistribution:

• In the Western, there’s no system.
• In the Northern, there’s a system and it’s fantastic.
• In the Eastern, the system is reformed from within.
• In the Southern, the system has to be reformed from the outside.

Yes, this is classic Facebook-era Buzzfeed crap. It's devoid of the academic rigor required for building guns, AI, etc.

But this crap is fun to think/talk about. For better or worse, we tend to build crap we think/talk about. Man creates myth; myth creates machines.

Cyberpunk stories tend to be Westerns/Southerns. It's dystopia. The worst versions of technocratic capitalism reign; society is mired in Kafkaesque complexity; corporations wield automation to extract dregs from the poor. Institutions (or lack thereof) require violent revolution. Everybody is trapped.

If you want Northern/Eastern sci-fi, consider solarpunk. Humans embrace sustainable living and personal responsibility; technology creates happiness/health/wealth for all. Institutions can be reformed. Good triumphs.

In Snow Crash (1992), Neal Stephenson depicted a cyberpunk "metaverse", which became The Metaverse™️ in 2021.

By 2012, Stephenson was already writing (and advocating for) solarpunk stories:

There's an old saying that when you have a hammer, everything looks like a nail.
So my hammer happens to be the ability to write science fiction.
…
One of the ideas that emerged from that Future Tense conference a year ago was that of producing some new science fiction stories that were aimed at describing future alternative societies in which big things had gotten done.
Which is a thing that science fiction hasn't been doing for a while.
I mean, this is all fine.
During about the same time that we kind of stopped innovating on a big scale, at least in the physical world, science fiction has become sort of inward looking, postmodern, introspective, focused more on social stuff.
It's a good and healthy thing to have done.
But in the current climate, it seems like kind of a strange and radical innovative idea to write science fiction as a throwback to the golden age of science fiction stuff, the kind of techno-optimistic stuff that I used to read when I was a kid.
The general unifying principle of what I'd like to see written for this project is that it should talk about innovations such that a young person just starting their career today could read one of these stories and say, "Hmm -- This doesn't exist now, but if I start working on it today, by the time I retire, it might exist."

-- Neal Stephenson, We Solve for X (2012)

Mutual Destiny might be impossible, but pessimism is an anti-myth that makes Mutual Destruction inevitable. Pessimism is a luxury we can no longer afford.

The universe doesn't cater to anthropocentricsm. Myth may prove insufficient. It's okay. Life will end. The music always stops; don't let the future's finale spoil the song.

We loot fire from gods. We build saunas, flamethrowers, computers, pistols, etc. When power becomes plenty, equalizers tend to make some men more equal than others. Man makes myth makes machine; myth makes man into man's machine.

The future is cast in sweat and stone and serif and steel and silicon. It's written everywhere, by everything, by everyone.

The good news is that we have more than guns. The bad news is that we have more than guns.

God created men; sometimes somebody/something makes them equal.

It's not enough to breathe -- my gluttonous heart wants to impose its imagination on Earth and all its inhabitants.

I want freedom, money, affection, play, power, validation, fulfillment, etc.

Of course I already have these things, but enough never seems enough.

These desires manifest themselves as an endless backlog of ideas and projects.

My backlog grows; my lifespan dwindles. I feel powerless against this trickle of time. When my optimism hits its limits, I mourn so many stillborn dreams -- breaking my back to bury impossible futures.

I want to want fewer futures, but I'm often too weak to put possibilities out of their misery. I'm learning to let go, but maybe letting go takes a lifetime.

My brain came pre-installed with Human OS; loss aversion will squander CPU until I install security patches (e.g. Taoism, Zen, stocism).

But I think I'm allergic to enlightenment. Meditation is difficult, quiet is boring, courage is scary, desire is addicting, etc.

"Dream themes" are my spiritual duct-tape. When desire outpaces optimism, I distill my projects into metaprojects [sic].

Most humans lack the resources to pursue megaprojects. Those who wage one-man wars-of-attrition guarantee failure.

A metaproject is an itch which scratches many itches.

Example: You've been wanting to take cooking classes, but you've also been wanting to join an improv group. If you don't have time/resources for both of these projects, you might choose a metaproject like "weekly dinner party with funny friends" -- it doesn't strictly meet the requirements from either project, but it might fulfill some deeper desire.

So many bites. Scratching harder, clawing at skin, fighting flesh -- loss is inevitable under these conditions. Ignore that immediate irritation and erect a mosquito net. If your net works, it'll crowd with friends, finally finding relief from similar itches.

Metaprojects agglomerate. Your nets' threads tend to tangle together into an anti-mosquito tapestry. In those chaotic quilting patterns, you develop vocabulary to describe/distinguish distinct itches.

Your ultimate metaproject is precisely you and inevitably whoever you choose to become. It never feels that way. It feels like you're building an OS, learning Mandarin, writing another novella -- no, no -- you're writing an autobiography with blood.

There is an old christian phrase -- Crux medicina mundi -- the Cross, the medicine of the world -- a phrase which is rather remarkable in that it suggests that religion is a medicine rather than a diet. The difference is, of course, that medicine is something to be taken occasionally -- like penicillin -- whereas a diet is regular food. Perhaps this analogy cannot be pressed too far, since there are medicines like insulin which some people have to take all the time. But there is a point to the analogy -- a point expressed in another Latin saying, not at all Christian, since its author was Lucretius: Tantum religio potuit suadere malorum (Too much religion is apt to encourage evil). I am not thinking so much of the exploitation of the poor by a corrupt priesthood, or of the obvious evils of zealotry and fanaticism. I am thinking, rather, of the old Buddhist metaphor of the doctrine which is like a raft for crossing a river. When you have reached the opposite shore, you do not carry the raft on your back, but leave it behind.

There is something here which applies not only to the mere handful of people who might be said to have reached the opposite shore, but to most of us. To carry out the metaphor a little: if you are going to cross the river, you must make haste, for if you dally on the raft, the current will carry you downstream, and out to the ocean -- and then you will be stuck on the raft forever. And it is so easy to get stuck -- on the raft, on religion, on psychotherapy, on philosophy. To use another Buddhist simile: The doctrine is like a finger pointing at the moon, and one must take care not to mistake the finger for the moon. Too many of us, I fear, suck the pointing finger of religion for comfort, instead of looking where it points.

Now it seems to me that what the finger of religion points at is something not at all religious. Religion, with all its apparatus of ideas and practices, is altogether a pointing -- and it does not point at itself. It doesn’t point at God, either, for the notion of God is part and parcel of religion. I might say that what religion points at is reality, except that this merely puts a philosophical notion in place of a religious one. And I can think of a dozen other substitutes for God or reality. I could say that it points at one’s true Self, at the eternal Now, at the nonverbal world, at the infinite and ineffable -- but really none of this is very helpful. It’s just putting one finger in place of another. When Joshu asked his teacher Nansen, "What is the Tao, the Way?" Nansen replied, "Your everyday mind is the Tao."

But this doesn’t help, either, for as soon as I try to understand what is meant by my everyday mind, and then try to latch on to it, I am just sucking another finger. But why does this difficulty arise? If someone actually points his finger at the moon, I have no difficulty in turning and looking at the moon. But the thing at which these religious and philosophical fingers are pointing seems to be invisible, so that when I turn to look there is nothing there, and I am forced to go back to the finger to see whether I understood its direction correctly. And sure enough, I find time and time again that I made no mistake about its direction -- but for all this I simply cannot see what it’s pointing at.

All this is equally exasperating for the person who is doing the pointing, for he wants to show me something which, to him, is so obvious that one would think any fool could see it. He must feel as we all feel when trying to explain to a thick-headed child that two times zero is zero and not two, or some other perfectly simple little fact. And there is something even more exasperating than this. I am sure that many of you may, for a fleeting moment, have had one clear glimpse of what the finger was pointing at -- a glimpse in which you shared the pointer’s astonishment that you had never seen it before, in which you saw the whole thing so plainly that you knew you could never forget it… and then you lost it. After this, there may be a tormenting nostalgia that goes on for years. How to find the way back, back to the door in the wall that no longer seems to be there, back to the turning which led into paradise -- which wasn’t on the map, which you saw for sure right here. But now there is nothing. It is like trying to trace someone with whom you fell in love at first sight, and then lost touch; and you go back to the original place of meeting again and again, trying in vain to pick up the threads.

If I may put it in a way which is horribly cumbersome and inadequate, that fleeting glimpse is the perception that, suddenly, some very ordinary moment of your ordinary everyday life, lived by your very ordinary self, just as it is and just as you are -- that this immediate here-and-now is perfect and self-sufficient beyond any possibility of description. You know that there is nothing to desire or seek for -- that no techniques, no spiritual apparatus of belief or discipline is necessary, no system of philosophy or religion. The goal is here. It is this present experience, just as it is. That, obviously, is what the finger was pointing at. But the next moment, as you look again, the instant in which you are living is as ordinary as ever, though the finger still points right at it.

However, this irritatingly elusive quality of the vision to which the finger points has an extremely simple explanation, an explanation which has to do with what I said at the beginning about getting rid of the raft when you have crossed the river, about taking religion as a medicine but not as a diet. For purposes of understanding this point, we must take the raft as representing the ideas or words or other symbols whereby a religion or a philosophy expresses itself, whereby it points at the moon of reality. As soon as you have understood the words in their plain and straightforward sense, you have already used the raft. You have reached the opposite bank of the river. All that remains now is to do what the words say -- to drop the raft and go walking on the dry land. And to do this, you must drop the raft. In other words, you cannot, at this stage, think about religion and practice it at the same time. To see the moon, you must forget the pointing finger, and simply look at the moon.

This is why all the great Asian philosophies begin with the practice of concentration, that is, of attentive looking. It is as if to say, "If you want to know what reality is, you must look directly at it and see for yourself. But this needs a certain kind of concentration, because reality is not symbols, it is not words and thoughts, it is not reflections and fantasies. Therefore to see it clearly, your mind must be free from wandering words and from the floating fantasies of memory." To this we are probably apt to reply, "Fine, but this is easier said than done." There always seems to be a problem about translating words into action, and this problem seems to be peculiarly acute when it comes to the so-called spiritual life. Faced with this problem, we back up and start to busy ourselves with a lot of discussion about methods, techniques, and other aids to concentration. But it should be simple enough to see that this is nothing but procrastination and postponement. You cannot, at the same time, concentrate and think about concentrating. It sounds almost silly to say it, but the only way to concentrate is to concentrate. In actually doing it, the idea of doing it disappears -- and this is the same thing as saying that religion disappears when it becomes real and effective.

Now a great deal of the talk about the difficulty of action, or the difficulty of concentration, is sheer nonsense. If we are sitting down together at a meal, and I say to you, "Please pass the salt" -- you just do it, and there is no difficulty about it. You do not stop to consider the right method. You do not trouble yourself with the problem of how, when you have picked the saltshaker up, you are going to be able to concentrate on it long enough to bring it to my end of the table. Now there is absolutely no difference between this and concentrating the mind’s attention to see into the nature of reality. If you can concentrate the mind for two seconds, you can do it for two minutes, and if you can do it for two minutes, you can do it for two hours. Of course, if you want to make this kind of thing horribly difficult, you begin to think about timing yourself. Instead of concentrating, you begin to think about whether you are concentrating, about how long you have concentrated, and about how much longer you are going to keep it up. All this is totally off the point. Concentrate for one second. If, at the end of this time, your mind has wandered off, concentrate for another second, and then another. Nobody ever has to concentrate for more than one second -- this one. This is why it is quite literally off the point to time yourself, to compete with yourself, and to bother about your progress and success in the art. It’s simply the old story of making a difficult job easy by taking it one step at a time.

There is, perhaps, another difficulty -- and this is that in the state of concentration, of clear unwavering attention, one has no self -- that is, no self-consciousness. This is because the so-called self is a construct of words and memories, of fantasies which have no existence in immediate reality. The block or stoppage which so many of us feel between words and action, between symbol and reality is actually a case of wanting to have one’s cake and eat it. We want to enjoy ourselves, and fear that if we forget ourselves there will be no enjoyment -- an entertainment without anyone present to be entertained. This is why self-consciousness is a constant inhibition of creative action, a kind of chronic self-frustration, such that civilizations which suffer from an overdose of it go raving mad, invent atom bombs and blow themselves up. Self-consciousness is a stoppage because it is like interrupting a song after every note so as to listen to the echo, and then feeling irritated because of the loss of rhythm.

This is all really a case of our own proverb, "a watched pot never boils." For if you try to watch your mind concentrate, it will not concentrate. And if, when it is concentrated, you begin to watch for the arrival of some insight into reality, you have stopped concentrating. Real concentration is therefore a rather curious and seemingly paradoxical state, since it is at once the maximum of consciousness and the minimum of ego-feeling, which somewhat gives the lie to those systems of Western psychology which identify the conscious principle with the ego. Similarly, it is the maximum of mental activity or efficiency, and the minimum of mental purposiveness, since one cannot simultaneously concentrate and expect a result from concentration.

The only way to enter into this state is precipitately -- without delay or hesitation, just to do it. This is why I ordinarily avoid discussion of all the various kinds of Asian meditation techniques, such as Yoga. For I am inclined to feel that for most Westerners, these are not aids but obstacles to concentration. It is not unaffected and natural for us to assume the lotus posture and go through all sorts of spiritual gymnastics. So many Westerners who do this kind of thing are so self-conscious about it, so preoccupied with the idea of doing it that they never really do it at all. For the same reason, I am rather leery of too much Zen -- especially when it means importing all the purely incidental apparatus of Zen from Japan, all the strictly technical formalities, and all the endless and pointless discussion about who has or hasn’t attained satori, or about how many koans one has solved, or how many hours a day one sits in zazen, or meditation. This sort of thing is not Zen or Yoga; it is just a fad, just religiosity, and is precisely self-consciousness and affectation rather than unselfconsciousness and naturalness. If, however, you can really do the thing itself -- that is, if you can learn to wake up and concentrate at the drop of a hat -- you can take or leave the trimmings as you will. For the fear of exoticism should not prevent us from enjoying the really beautiful things which Asian culture has to offer -- Chinese painting, Japanese architecture, Indian philosophy, and all the rest. But the point is that we cannot really enter into the spirit of these things at all unless, in the first place, we can acquire the special kind of relaxed concentration and clear-sightedness which is essential for their proper appreciation.

Of themselves, they will not give us that capacity -- which is something innate. If you have to import it from Asia, you do not have it at all. Therefore, the important thing is simply to begin -- anywhere, wherever you are. If you happen to be sitting, just sit. If you are smoking a pipe, just smoke it. If you are thinking out a problem, just think. But don’t think and reflect unnecessarily, compulsively, from sheer force of nervous habit. In Zen, they call this having a leaky mind -- like an old barrel with open seams which cannot contain itself.

Well, I think this is enough medicine for tonight. So let’s put the bottle away, and go out and look at the moon.

April 17, 1955

They tell us that something is waiting for us on The Other Side, that death may be a pilgrimage and not a destination, that the afterlife is a warm awakening after the fretful dream of life.

— Death Be Not a Stranger

The joke wasn't always about a suicidal bird.

By 1847, it had become a well-known anti-joke. Instead of a typical punchline, the chicken joke purposefully delivers a disappointing resolution.

In 1899, Henry H. Bliss was struck by a taxicab -- the first recorded car casualty in the US.

Before cars, people used vehicles called "horses". The non-LIDAR autopilot was ahead of its time, but the market was never going to accept 1HP and a 30-mile range. This is why Americans distrust European imports.

The US made more cars, faster cars, heavier cars; one could maim/kill oneself by stepping into oncoming traffic. All high-speed roads became portals to The Other Side.

Songs like Hit Me With Your Car and Crash the Car derive humor from such safety violations.

Any arbitrary animal could've crossed the road, but we coincidentally chose the "chicken" -- an enduring symbol of cowardice.

The way that they did and to grin like lions
Upon the pikes o’ th’ hunters. Then began
A stop i’ th’ chaser, a retire; anon
A rout, confusion thick. Forthwith they fly
Chickens the way which they ⌜stooped⌝ eagles; slaves
The strides ⌜they⌝ victors made; and now our cowards,
Like fragments in hard voyages, became

-- Shakespeare, Cymbeline (1623)

In games of chicken, players demonstrate courage by yielding later than other players. Game theorists model such payoff matrices like this:

This game normally has three Nash equilibria (i.e. stable strategies): (1) always chicken, (2) never chicken, or (3) match your opponent's stochastic strategy.

But not all chicken games are symmetric. When a lone man challenges armored vehicles, it feels callous to cram life into a lopsided payoff matrix.

The chicken joke is an anti-joke that morphed into an actual joke, but we've induced jamais vu. Over and over again, humans teach the new humans that pointlessness is the point.

But when we search for meaning in the seemingly meaningless, we discover motor vehicles, mathematics, misery, metahumor -- much more than a mere joke. Pulling that fraying string in your underpants, you find that the entire universe unfurls and, against all odds, everything remains connected.

Chinese authorities largely ignored Taylor Swift's T.S. 1989, which unintentionally memorialized the Tienneman Square (TS) 1989 incident.

Those hoodies were likely made in China and conceived in the United States -- Taylor Swift's US propaganda outsourced to Chinese sweat shops, then resold to US consumers to fuel Chinese propaganda, and then sensationalized/compressed into clickbait for US media outlets to advertise more McNuggets (which are ostensibly chicken).

There's nothing humorous about suicidal chickens, nor traffic fatalities, nor game theory, nor Tienneman Square, nor Taylor Swift. But it's funny if you think about it.

If my mom wanted good art on her fridge, she could've purchased reprints of works by Vermeer, Lichtenstein, Wyeth, etc. But she didn't want good art -- she wanted my art.

Somebody with good taste could've made my website, but then it wouldn't be mine.

To bake bread, many feel compelled to grow wheat, mine salt, culture yeast, etc. Not me. My puerile palate yearns for buckets of Olive Garden breadsticks.

That's okay. Your "mine" is not my "mine".

Some folks run self-hosted websites on solar power. Others share wisdom on Substack. This guy posts manufacturing deep-dives to YouTube. Gwern does whatever this is.

It's an itch -- a feeling that something is really important, and you need to do something about it, and nobody else can possibly do it except you.

I am not compelled to bake bread, nor provision servers, nor build chips. Yet that itch pervades, and it pulls me toward humor and systems and life and software and structure. And when emotion becomes unbearable, it erupts out of me: fiction, HTML/CSS, crappy robots, sad songs, and so on.

My website is my website.

In the past, I just wanted simplicity and friendliness: remove noise, boost contrast, flatten menu depth, boring HTML, reduce CSS, avoid JS, etc.

My website looked like this:

But things started going sour when I decided to occupy as much horizontal space as possible.

The plan was simple: slap flex-wrap on a ul. Unfortunately, text wraps too. It was unclear where one link ended and the other began. Some folks read inline and others perceive inline-block.

More whitespace? Yikes. Borders around each link? No way. Dots between the links? Yuck.

So let's vary the links! The chaos you see on my homepage comes from a few simple rules:

li:nth-child(4n + 0) { transform: rotate(1deg); }
li:nth-child(4n + 1) { transform: rotate(-0.6deg); }
li:nth-child(4n + 2) { transform: rotate(0.5deg); }
li:nth-child(4n + 3) { transform: rotate(-0.75deg); }

li:nth-child(6n + 0) { font-family: Times; }
li:nth-child(6n + 1) { font-family: Helvetica; }
li:nth-child(6n + 2) { font-family: Georgia; }
li:nth-child(6n + 3) { font-family: Times; }
li:nth-child(6n + 4) { font-family: Arial; }
li:nth-child(6n + 5) { font-family: "Trebuchet MS"; }

I originally chose coprime integers for more variation, but I rather liked the subtle repetition in this pattern.

I love minimalism and hate sterility. I sprinkled three additional surprises to evoke a "used bookstore" feeling:

li:nth-child(5n + 2) { font-weight: 100; }
li:nth-child(7n + 2) { letter-spacing: -1px; }
li:nth-child(41n + 31) { transform: rotate(181deg); }

The web remains an interactive medium. I wanted my site to react to cursor movement without JS; this CSS produced a pleasant "touching grass" feeling:

li:nth-child(2n + 0):hover { transform: rotate(-2deg); }
li:nth-child(2n + 1):hover { transform: rotate(2deg); }

Okay, now it reacts to cursor movements, but I also wanted to exaggerate that scrolling feeling without scrolljacking. Simple textured backgrounds make a webpage feel more like a page. So I synthesized texture with css-doodle:

svg {
  viewBox: .5 .5 10 10;
  fill: #000;
  circle*1000 {
    cx, cy: @r(10), @r(10);
    r: @r(.005, .01);
  }
}

So many little dots. In light mode, they become dust on paper. In dark mode, they're stars in the sky.

Today, my site looks like this:

Soon it will become something else entirely. Because it's my website and I'm perpetually becoming somebody else.

You'll change too. Your passions and values will pollinate; your ugly thing -- whatever it is -- will come alive again and again.

I can't live near friends right now, but I can synthesize some propinquity.

iOS's Find My enables friends/family to track my location in real-time. As somebody who hates notifications and SMS, this tech is godsend. My wife knows which coffee shop I'm at, my friends know exactly how much traffic I'm stuck in, etc.

I sacrifice my own privacy for convenience, but I never expect others to do the same. All my friends/family should feel entitled to privacy. There is no shame in unrequited location sharing.

Unlike read receipts, I do not expect the social norms on location-tracking to change any time soon. Most of the benefits of live location are conferred to the sharer rather than the receiver.

I don't want to bother people whenever I fly from SEA to SFO/LAX/etc. I want friends to know when I land, and I want friends to join my festivities.

You cannot count on others to check your location, nor to be available for your flights/fancies. Deeper relationships demand effort/planning/coordination. This isn't a replacement for real plans -- it's a backup for happy accidents.

Luckily, Find My can also notify them when you're near their 'hood.

This tech becomes extra valuable as you accumulate friends across Earth. You'll find that it's the biggest small world after all, filled with familiar faces in far-away places.

Don't leave serendipity to chance.

Read my full sad-money mouth emoji proposal and/or submit your own idea.

2025/11/20 update:

Dear Taylor Troesh,

Thank you for submitting an emoji proposal for Sad Money-Mouth Face. We appreciate all of the effort that went into the preparation.

Each year, the Unicode Emoji Subcommittee receives far more emoji proposals than the very limited number that can be encoded. We are sorry to inform you that your proposal was not among those selected to move forward.

As a small, volunteer-run nonprofit we can’t provide individualized feedback on each proposal. We understand this may come as a disappointment. Thank you again for taking the time to contribute to the Unicode Standard.

Respectfully, The Unicode Emoji Standard & Research Working Group

Seeders & Leechers

When freebooting on the web, people participate in a sort of distributed iterated prisoner's dilemma. Everybody shares bandwidth; everybody risks prosecution.

These conditions naturally create "seeders" and "leechers" -- those who create surplus, and those who exploit that surplus.

You also attract scammers and (angelic) archivists.

Networks are characterized by their incentives. The seeder/leecher distribution is largely determined by risk/reward (e.g. payoff matrices).

One investigation showed that of 123 randomly selected downloaded files, 37 contained malware – about 30%.

-- via Wikipedia

Within a network, individuals exercise discretion; the sum of rational decisions determine the fate of the network. Sometimes these equilibria tend toward tragic commons.

But humans can act irrationally. Some scoundrels pay dearly to reap revenge. Some Good Samaritans sacrifice their lives for others. Game theory only works when people play the game.

Etiquette

Trust lubricates networks; nodes can skip verification to contribute more surplus. You don't need proof-of-work in a high-trust society.

TLS costs more than TCP.

One such verification shortcut is etiquette. When individuals follow certain norms/conventions, they're signaling a willingness to participate a high-trust game.

Pedigree is another shortcut.

I went to see Mrs. B (Rose Blumkin), carrying a 11/4-page purchase proposal for NFM that I had drafted…. Mrs. B accepted my offer without changing a word, and we completed the deal without the involvement of investment bankers or lawyers (an experience that can only be described as heavenly).

-- Warren Buffet, Berkshire Hathaway 2013 Annual Report

My ideal world runs on handshake deals, but unverified agreements invite exploitation. When a pot grows too large, people defect.

Ray Kroc allegedly forsook his handshake deal with the titular McDonald family.

Prior to April 2004, the free version of LimeWire was distributed with a bundled program called LimeShop (a variant of TopMoxie), which was spyware. Among other things, LimeShop monitored online purchases in order to redirect sales commissions to Lime Wire LLC. Uninstallation of LimeWire would not remove LimeShop. These objections were addressed in 2004 with the removal of all bundled software in LimeWire 3.9.4.

-- via Wikipedia

As wolves don sheep's clothing, etiquette evolves new signals. The meta changes. "Networking" events fill with leechers; seeders start secret high-trust clubs.

Reputation

Reputation is the evergreen shortcut. It is hard to earn, harder to keep, and nearly impossible to salvage.

Reputable BitTorrent archives remain. Consider donating to archive.org, scihub, Anna's Archive, and LibGen.

To earn reputation, (1) act predictably and (2) maximize your seed/leech ratio.

Most real-world games are iterated. Predictable actors are more valuable than unpredictable ones.

Optimizing seed/leech ratio is a wicked problem. Nobody can define what seeding/leeching means for you, nor whether you're succeeding, nor whether it leverages your unique life experience.

Open-source software culture is exemplary. Where can you make the most impact in OSS? Contributing to an existing project or starting a new one? To serve the status-quo or betray it? Solving a few big problems or lots of small problems? Individual contribution or management or governance? DPS, support, or tank?

When seeding your network, you learn how the system really works. By continued good-faith effort, you discover friction and opportunity.

I experienced this phenomenon on this blog. By sharing others' essays online (e.g. HN), I honed a sense of valuable/viral content. By consistently contributing such surplus, I've learned to anticipate specific wants/needs of the network. It's wholesome fun -- promoting friends' blogs and tickling the imagination of the masses.

Like money, you can apply leverage to reputation. By staking time/resources/connections on people, you extend your reputation like a line-of-credit. Each time this cycle succeeds, surplus can be reinvested in your local network.

As surplus grows, people become more tempted to defect. Beware greed; embrace "enough". Prune disreputable acquaintances. Adhere to your principles; continue to pursue others' wants/needs. Establish trustworthy neighbors and help them flourish.

It's difficult to identify/articulate "core" issues, and most polite folks will not advertise their troubles. People appreciate an opening for sincere dialogue: "What are you looking for right now?", "How can I help?", "Need any money for that?", and so on.

Lately, I've been working hard to (1) find "dream" jobs for friends, (2) find capital for friends' startups, and (3) find startups for my friends' funds. It costs me nothing to dramatically improve the lives of my loved ones. Ask friends what they want; go make it happen.

Extend trust; tragic commons are not inevitable. Don't let the leechers win. Flood this world with abundance.

And so I've been thinking about "compassionate" compilation. How can we learn to love our languages again? How can we reduce our energy footprint? How can we tame the chaos monkeys? How can we reignite the joy of simple software? How can we share our abundance as if recycling air?

The Modern Stack

Modern web computing looks vaguely like this:

• TSX → unspeakable horror → HTML/CSS/JS
• HTML/CSS/JS on CDN → HTTP → HTML/CSS/JS into DOM → process layout and run JS → virtual DOM
• Rust → ??? → LLVM IR → LLVM → server executable → Dockerfile → Docker image
• virtual DOM → DOM → browser → JSON → HTTP → JSON → server executable -> SQL → PG protocol → query planner → PG tuples → MVCC magic → PG protocol → server executable → JSON → HTTP → JSON → browser → DOM → virtual DOM

This is barely a map of the happy path. It skips error states, compiler internals, OS, CI, package management, containers, garbage collection, CPU caches, etc. How many allocations--

Nope. It's too much for my sad synapses. I cannot pretend to comprehend the journey that my data take to load a single web app.

A Convenient Package

Computers are crafted at the nanometer scale; they are the pinnacle of human precision. But software squanders this power. Our precision engines evoke frustration, bugs, and inconsistency -- "did you try turning it off and on again?". Codebases devolve into chimeras of LEGO, Lincoln Logs, cement, popsicle sticks, duct tape -- software cannot succeed like this.

But to wrest LEGO and Lincoln Logs from y'all would be folly. I cannot coerce an entire industry to converge on compatible standards. No, no -- please keep your familiar tools/toys.

Here's my proposal: we choose one "good enough" data layout, and we squeeze it for as much mileage as it can bear. Such a format must encode most popular formats, respect bandwidth, support single-pass execution, allocate sparingly, afford sublinear lookup (for lists/dicts), and remain simple to understand/implement. Good news: our computing forefathers already solved these problems -- we just need to cram them into a single convenient package.

tl;dr flat scraps = bootleg MsgPack + bootleg IPFS + bootleg XSD + bootleg FORTH

Boring Data

Integers, floats, strings, bytes, arrays, maps, variants, types -- any serialization format that encodes these data will do. CBOR and MsgPack are reasonable starting points.

Flat scraps are still in the discovery phase! Meanwhile, check out Max Bernstein's elegant ~100 LOC scrapscript serializer.

Most popular markup/config/data formats (JSON, YAML, XML, CSS, HTML, CSV, Dockerfile, etc.) can be efficiently encoded as CBOR/MsgPack (sketched here as scrapscript types):

()

; csv :
    list text

; css :
    list css-rule
; css-rule :
    | #style { selector : text, declarations  : list decl }
    | #at { name : text, prelude : text, block : maybe (list decl) }
; css-decl :
    { property : text, value : text, important : bool }

; html :
    xml

; xml :
    | #text text
    | #float float
    | #bool bool
    | #object (list xml)
    | #doctype { name : text, attrs : dict text xml }
    | #tag { name : text, attrs : dict text xml, body : xml }

; yaml :
    json

; json :
    | #null
    | #bool bool
    | #int int
    | #float float
    | #text text
    | #list (list json)
    | #dict (dict text json)

; dockerfile :
    { base : (pair text text)
    , instructions : list (
        | #from (pair text text)
        | #run text
        | #copy (pair (list text) text)
        | #workdir text
        | #env (list (pair text text))
        | #expose (list int)
        | #volume (list text)
        | #user text
        | #entrypoint (list text)
        | #cmd (list text)
        | #comment text
      )
    }

CSS parsers should live in editors, not browsers. You can still write as much CSS as you want -- just don't send it around as CSS text. Text is floppy. It's hard to cache, hard to compress, hard to parse, hard to validate, etc. Send data structures instead.

Shareable Data

By shoving all these data structures into the same serialization format, all software can reap the rewards of common infrastructure: shared compression, shared schema validation, shared optimizations, shared versioning, etc.

Scrapscript (and flat scraps) extend "sharing" further. You can replace any "scrap" of data with its cryptographic hash to reference it and reuse it. For example, we could serialize HTML pages like this:

<html>
  <html title="meta" href="proxy.php?url=https%3A%2F%2Ftaylor.town%2Fscrap%3A%2F%2F%24e9a23cbc455158951716b440c3d165e0"/>
  <body>
    <html title="header" href="proxy.php?url=https%3A%2F%2Ftaylor.town%2Fscrap%3A%2F%2F%24099fb995346f31c749f6e40db0f395e3"/>
    <main>
      <p>hello world</p>
    </main>
    <html title="footer" href="proxy.php?url=https%3A%2F%2Ftaylor.town%2Fscrap%3A%2F%2F%24d7eb6b340a11a367a1bec55e4a421d949214759f"/>
  </body>
</html>

Suddenly, without any syntax changes, every format acquires the powers of git at the semantic level. Replace any chunk of JSON/CSV/etc with its hash and it can hit a cache on the other side of the wire.

It gets better. We can use scrap maps to name (and version) arbitrary hashes:

<html>
  <html href="proxy.php?url=https%3A%2F%2Ftaylor.town%2Fscrap%3A%2F%2Ftaylortown%2Fexample%2Fmeta"/>
  <body>
    <html href="proxy.php?url=https%3A%2F%2Ftaylor.town%2Fscrap%3A%2F%2Ftaylortown%2Fexample%2Fheader"/>
    <main>
      <p>hello world</p>
    </main>
    <html href="proxy.php?url=https%3A%2F%2Ftaylor.town%2Fscrap%3A%2F%2Ftaylortown%2Fexample%2Ffooter"/>
  </body>
</html>

But wait -- it gets even better.

Flat scraps have a type system. Imagine succinct JSON Schema, friendly XSD, serializable Haskell, etc. You can reuse all the exact same tools for maximum strictness:

package-json
; package-json :
    { name : text
    , version : text
    , description : maybe text
    , main : maybe text
    , types : maybe text
    , scripts : dict text text
    , repository : maybe { type : maybe text, url : text, directory : maybe text }
    , keywords : list text
    , author : maybe { name : text, email : maybe text, url : maybe text }
    , license : maybe text
    , bugs : maybe { url : maybe text, email : maybe text }
    , homepage : maybe text
    , dependencies : dict text text
    , devdependencies : dict text text
    , peerdependencies : dict text text
    , optionaldependencies : dict text text
    , engines : maybe { node : maybe text, npm : maybe text }
    , private : maybe bool
    , publishconfig : maybe { registry : maybe text, access : maybe text }
    , workspaces : maybe (list text)
    }

You needn't f*ck around nor find out. You can infer/enforce types at runtime or compile time. You can ensure that all configs and messages are truly compatible.

You may enjoy my talk from UNSOUND '24.

Programs

But that's just static data. You can also efficiently encode arbitrary programs this way. Code can be data, too.

By extending CBOR/MsgPack with executable data, we unlock new superpowers: dynamic configs, templating engines, RPCs, client-side codegen, hot reload, Smalltalk-esque images, etc.

Behold the reigning champion of simple computing: FORTH. Stack languages are the simplest means of practical memory/compute. Uxn is exemplary.

Why not WASM? LLVM IR? In short, they're not simple enough for my tastes. I think humans write more code than we can responsibly maintain. In my experience, bloat is the nastiest unsolved problem in software; slow/buggy software is holding us back.

Most people consider reverse-polish notation an eye blight, but computers kinda prefer it over prefix and infix notations.

We might be able to get the best of all worlds by embedding "performance hint" operators: explicit allocations, SIMD, etc.

{ add1 = n -> n + 1 }

-- flat scrap (bytes):
--   { "add1" = expr[var(n) var(n) 1 op(+) op(->)] }

Here's my compromise: flat scraps use RPN; scrapscript reflects them as an infix notation.

While I've been off exploring flat scraps, Max (and friends) have been turning scrapscript into a real high-level programming language with a world-class compiler!

The Scrap Stack

This is the vision I'm working toward with flat scraps:

• lex/parse: scrapscript → flat scrap
• eval: flat scrap → flat scrap
• optimize: flat scrap → flat scrap
• print: flat scrap → scrapscript
• compile: flat scrap → executable
• deploy: flat scrap → tcp → flat scrap
• serve: flat scrap → tcp → executable → tcp → flat scrap
• query: flat scrap → tcp → flat scrap → dirtdb → flat scrap → tcp → flat scrap

It looks stupid, because yes -- it's stupid.

Computing can be simpler.

• Help me release smel shell.
• Contribute to Max's compiler.

But for optimists (and lunatics), five weeks is plenty to start a company.

You probably have a dayjob. Exceed your employer's expectations. Don't accept paychecks you don't deserve. Work on your startup mornings (not evenings) and weekends. Save your PTO until the third week, and then start taking off Mondays/Tuesdays (not Thursdays/Fridays) if needed. If you can no longer maintain stellar quality at work, it's time to move on.

Week 1

Founders must adopt an investor mindset. If you want to create value, learn how to assess opportunity, how to leverage assets, and how to hedge risk.

It's okay to fundraise and it's okay to bootstrap. Either way, don't let ego rule you. Capital can be a tool like any other.

Investors don't choose startups, they choose founders. They want to multiply their money, and they want you to do it. But you can't just "pivot" a lousy personality. Nobody wants to bet on a billion-dollar idea that's chained to a fool.

If you are worth investment, then invest in yourself.

1. Get a haircut. Maintain a clean/fresh appearance. Any style will do.
2. Learn to listen. If most strangers don't describe you as "charismatic", you must upgrade your EQ. Read HTWFAIP, Motivational Interviewing, and Supercommunicators. Use AI to practice listening.
3. Hire a therapist. Launching a venture is hard. Secondhand-stress ruins relationships. Your spouse is not your therapist. If you vent more than you listen, your support system will avoid you in proportion to how much you need them.
4. Look in the mirror. Who are you? What values will you compromise? How do you want to behave? How do you want others to perceive you? What do you want living to feel like?
5. Get enthusiastic consent. If you can't sell your vision to your inner circle, you are not ready to start. Friends/family should call your startup idea "obvious". If they aren't ecstatic about your gameplan, you haven't (1) demonstrated competence/value or (2) hedged against known risks.
6. Take a headshot. A high-quality profile picture indicates that you were once worth a professional photo.
7. Become searchable. Investors hesitate to throw money at mysterious strangers. Update your LinkedIn work history. Also consider Googling yourself to find/delete unused accounts.
8. Upgrade your audio/video. Buy a mic (if you can afford it). Buy a webcam light (even if you can't afford it). If you've got Apple devices, buy a mount for Continuity Cam.
9. Go hands-free. As a business owner, you will be a slave to the telephone; invest in some comfortable bluetooth headphones so you can walk and talk.
10. Learn to send emails. Quick replies impress investors and customers. Respond to every email/SMS/voicemail within 12 hours (preferably less). Master the art of terse emails.
11. Accept AI. Founders wear all the hats. Pay the extra cash for Grok DeepResearch (great for web search) and Claude (best for everything else). LLM text has a pungent odor, so beware of copy/paste. And remember that LLMs bias toward "unsurprising" results; even correct advice can revert you towards the mean.

Week 2

Good businesses create non-zero-sum wealth. If you sell that wealth for dollars, you can create more wealth to sell.

Outside of theft and burglary, the only way to make money is to convince other people to give you their money.

1. Close a customer. A business with no customers is just a stressful hobby. Opt for FPC (First Paying Customer) before MVP. Nominal revenue (e.g. $1) counts. Don't prematurely automate; do boring manual labor and sell before you're ready.
2. Serve your customer. Deliver your promise. Compromise nothing. Treat your customer like a deity.
3. Upgrade. How can you make this customer exchange more delightful? Smoother? Less stressful? Adopt processes. Purchase tools. Hire people.

Week 3

The main thing is to keep the main thing the main thing.

Create wealth and sell it to customers. You will not succeed if you cannot (1) create wealth, (2) find customers, and (3) sell that wealth.

1. Close five customers. You can do this. You have something they need.
2. Serve your customers. Pamper them. No excuses.
3. Upgrade. Adopt/build/hire processes/tools/people that increase quality, improve consistency, increase speed, reduce cost, etc.
4. Land a loan/investment. By working with customers, you've probably identified a concrete use for capital. Convince a family member or friend to send a small check ($1k-$25k). Simple loans are easiest; you can remain a sole-proprietor indefinitely and skip loads of paperwork. If you want to exchange equity (i.e. a security), they probably need to be an accredited investor (i.e. "millionaire"); you'll need to incorporate (e.g. Stripe Atlas) and manage stakeholders (e.g. AngelList). Each investment -- no matter how small -- is faith in you. Make every penny count; repay their wagers tenfold.
5. Follow up. You're sending more emails; don't wait for people. Pester Plan A, start Plan B, and devise Plan C. This is your life now.
6. Create visual media. You will soon be sharing pitch decks, ads, etc. You need professional illustrations, a "good enough" logo, high-quality photos (or renders), explainer videos, etc. You might have good enough taste to do it yourself, but you do not have enough time. Hire somebody (e.g. Fiverr) to produce more materials than you think you need. Don't be lazy -- stock photos and AI images reek of corporate cringe.

Week 4

Don't lose focus. Share your wealth.

1. Delight existing customers. This is (and will forever be) your main duty.
2. Meet new customers. Who are your customers? Where do they go? What are their wildest hopes/dreams?
3. Upgrade. Better. Faster. Cheaper.
4. More loans/investments. Befriend leverage. Deploy capital.
5. Launch a landing page. The internet is cool, but don't overdo it. Choose a simple website host (e.g. Squarespace, Shopify). Embed/link a webform for leads.
6. Advertise. Yes, everybody hates ads. Swallow your pride and advertise on Instagram, Google, Reddit, YouTube, LinkedIn, etc.
7. Share your pitch deck. If you're going to fundraise, start now. Build a pitch deck. Do not reinvent the wheel; investors expect slides with specific information. If you're lucky, somebody will spend 20 seconds scrolling through it on their phone. Prefer pictures/charts over words; Claude/ChatGPT can plot data quickly. Your goal is to (1) prove competence, (2) guarantee profits, and (3) mitigate risks. Ask Grok DeepResearch to match you with compatible VCs/incubators/accelerators; submit your deck to each website.

Week 5+

Put everything together. Construct an engine that predictably transforms money into wealth, and then wealth into more money.

1. Grow. Delight customers. Meet customers. Upgrade. Borrow. Advertise. Repeat.
2. Pitch. If fundraising, submit pitches. Listen. Hedge risks. Refine your thesis. Repeat. Don't be greedy, and never cash a check that is chained to a fool. Revere $1K checks, $1M checks, $1B checks. Somebody believes in you; don't betray that trust. Live your values without exception. Protect every damn ounce of reputation.
3. Recruit. Go fast alone; go far together. Find friends. Surround yourself with your favorite people; bring out their best. Help them achieve their wildest dreams, and don't get left behind.

This is just the beginning. The rules are simple, but the game is grueling:

• When demand is scarce, listen to customers. You should (A) increase quality/experience, (B) reduce costs, (C) educate customers, and/or (D) admit defeat.
• If capital can help, ask for it.
• If you've got more demand (customers) than supply, you should (A) raise prices and/or (B) increase supply.
• If each new customer brings $10 of profit, you should spend up to $10 to find a new customer.

If you succeed, share that abundance with others. Remember where you're going, remember where you came from, and choose who you're becoming.

I'm as charismatic as a root canal.

But I'm determined to grow. Books like HTWFAIP and How to Have Impossible Conversations and How To Talk So Kids Will Listen contain countless gems to evoke the best from people.

Unfortunately, I can't use that wisdom. When it comes time to put my mouth where my mouth is, I drown in the speed of normal conversation.

People somehow learn this stuff. There's literally school for it. How do they learn to talk and listen?

There are no shortcuts. In licensed therapy programs, professionals evangelize conflicting frameworks and nobody knows what's going on. I'm here to share one such framework.

Motivational Interviewing

Motivational Interviewing was developed for substance abuse rehabilitation, but it's grown popular with clinical psychologists, therapists, counselors, etc.

I'm no professional -- just some random internet person -- but MI has dramatically improved my listening skills.

My amateur summary of MI is that (1) people feel ambivalence, (2) change comes from within, and (3) "OARS" conversations hasten that change.

Ambivalence

I suddenly spotted that ambivalence everywhere. People frequently feel anxiety/grief about work, family, health, etc. These enormous feelings leak into conversations as venting, gossip, smalltalk, and current events.

Street Epistomology offers guides on how to encourage productive dialogue. Consider using those techniques to help others explore beliefs and feelings.

Change

Watching somebody's brain "click" is a rare delight of life. All of a sudden, that face lights up -- loss to enlightenment.

These moments rarely happen during dialogue, because you can't change the brain through the ears.

Think about your own experience. Most "a-ha" moments don't occur in the classroom -- they happen while doing the homework. There is no substitute for first-person learning.

You cannot lecture somebody into changing beliefs/feelings/motivations, but you can totally watch friends do their homework.

Don't assume too much -- part of the magic is learning what homework they've assigned themselves.

OARS

When people share confused/conflicting feelings, you can use OARS:

• Open-ended Questions: Encouraging elaboration with "what," "how," and "tell me about" questions that explore feelings, values, and priorities while avoiding judgmental "why" questions that can shut down conversation.
• Affirmations: Recognizing strengths, efforts, self-awareness, and courage shown through expressing conflicting feelings, including positive qualities the person might not recognize in themselves.
• Reflective Listening: Demonstrating understanding of their perspective using both simple and complex reflections that capture underlying meanings and both sides of ambivalence, sometimes incorporating metaphors to represent emotional complexity.
• Summarizing: Collecting and linking important elements by highlighting key tensions, structuring summaries to show relationships between different feelings, and ending with an invitation for correction or further exploration.

Yeah, I hate social-science acronyms too. I've internalized it as an algorithm:

1. Move conversations along via "You…" statements. Where do you think they're going with this? e.g. "You're thinking about quitting.", "You're frustrated by your progress.", "You're unsure what to do next." If you don't know where they're going next, ask an open-ended question.
2. If you're impressed by somebody's strength/courage/etc, pay them a compliment. Never lie or patronize.
3. When they conclude a line of thought, ask an open-ended question.
4. When lots of tangents/threads are open, identify themes/patterns and try summarizing.

Practice your conversational skills with this LLM prompt: "Help me practice OARS via role-playing. You are a friend I haven't seen in a few weeks."

Examples

I'm thinking about trying that new restaurant downtown, but I saw some mixed reviews online. Some people loved it and others said the service was terrible.

• Open-ended Question: "What kinds of things make or break a restaurant experience for you?"
• Affirmation: "You're doing your homework before spending your money there."
• Reflective Listening: "You're curious about the place but hesitant because of what you've read."
• Summarizing: "You want to check out this new spot, but the inconsistent reviews have you wondering if it's worth the risk of having a disappointing night out."

Everyone's talking about that new show, but I watched three episodes and just couldn't get into it. I feel like I'm missing something.

• Open-ended Question: "What about it didn't click for you?"
• Affirmation: "You gave it a fair chance instead of just going along with the hype."
• Reflective Listening: "You're feeling a bit out of step with what everyone else seems to be enjoying."
• Summarizing: "So while this show is getting all this buzz, it just didn't connect with you despite giving it several episodes, and now you're wondering if there's something you're not seeing that others are."

Did you hear about that big tech company layoff? They cut 5000 jobs after reporting record profits last quarter. It seems so unfair.

• Open-ended Question: "What do you think is really behind these kinds of corporate decisions?"
• Affirmation: "You're keeping up with business news and noticing the contradictions there."
• Reflective Listening: "The timing of cutting jobs right after announcing big profits feels wrong to you."
• Summarizing: "So you're seeing this disconnect between a company doing well financially and still eliminating thousands of jobs, which raises questions about their priorities and values."

I hate my job. My boss micromanages everything I do, and I feel like I'm wasting my talents. But I can't afford to quit.

• Open-ended Question: "What bugs you most about your everyday work life?"
• Affirmation: "You really know your worth and you're being smart about the money side of things too."
• Reflective Listening: "Sounds like you're stuck between a job that's dragging you down and bills that need to be paid."
• Summarizing: "So your boss's hovering is driving you crazy, and you know you could be doing better things with your skills. But right now, the financial reality is keeping you from making a move."

I know I should exercise more and eat better. Every Monday I start a new routine but by Wednesday I'm back to my old habits. I just don't have the willpower.

• Open-ended Question: "What tends to throw you off track around Wednesday?"
• Affirmation: "I notice you keep trying every week - that takes some real persistence."
• Reflective Listening: "It's pretty frustrating when you start strong but can't seem to keep it going."
• Summarizing: "You want those healthier habits and you give it a fresh shot every week. You start off great, but something happens a couple days in that knocks you off course, and that's got you thinking maybe you just don't have what it takes."

I've been offered two jobs. One pays better but requires long hours. The other is more aligned with my interests but the salary is lower. I've been going back and forth for days and can't decide.

• Open-ended Question: "Besides the money and hours, what really matters to you in a job right now?"
• Affirmation: "You're not jumping at the first offer - you're really thinking this through."
• Reflective Listening: "You're torn between the paycheck and doing something you actually care about, and it's stressing you out."
• Summarizing: "So you're at this fork in the road - more money but less life, or work you care about but tighter finances. It's tough because both paths speak to different things you value."

My partner and I keep having the same argument. They say I'm not communicative enough, but when I try to talk, they interrupt or criticize what I'm saying. It's easier to just stay quiet.

• Open-ended Question: "What would good talking between you two look like?"
• Affirmation: "You're pretty tuned in to what's happening between you two."
• Reflective Listening: "You're in this loop where trying to open up just leads to feeling shut down, so why bother?"
• Summarizing: "So they want you to talk more, but when you do, you get cut off or criticized. That makes you clam up, which brings you back to square one. No wonder you're frustrated."

AIDS/Lifecycle is a great charity (donate), but it was insanely selfish of me to commit to something like this at the time. I am so grateful for Chelsea, who supports my ambitions and forgives my folly.

This decision defied logic. Dad bod claimed me long before the baby arrived. I knew nothing about cycling. I did not own a bike.

But I had to change something -- no, I had to change myself. To become somebody else, I decided to start living somebody else's life. I don't remember how the bicycle got involved.

I wasn't ready to be sober, nor to be a father, nor to start a company, nor to ride that bike.

Seriously, I rode the first 100 miles with two flat tires because I assumed all tubes needed exactly 12 PSI.

You'll never be ready for such things. Do them anyway.

Better writers accurately express ideas. They communicate their beliefs, their feelings, and the magnitude of their convictions. And then they choose word after word after word to share the view from their skull holes.

"Probably" and "maybe" dilute writing, but those words reduce intensity. I tend to err on the side of "too intense", but this is usually not how I feel -- it's just an artifact of weak writing.

I really wanted to use fancy words like "affect" and "valence" here, but I don't think I actually know what those words mean.

I'm still trying to solve this intesity dilemma, but it seems the only way to become a better writer is to write more. Consider this a disclaimer, an advance apology, and a big "student driver" sign for this blog.

To help me grow more quickly, please post feedback. Poke holes in my theories. Give counterexamples to my claims. Share your experience.

My therapist says that effective feedback follows this pattern: "When I see <phenomenon\>, I feel <emotion\>." For example: "When I see dishes in the sink, I feel anxious and overwhelmed." It's difficult (but so important) to remove judgements/assumptions when you're speaking about your experience.

Thank you for all the insightful comments across the link aggregators. Thank you for brightening up my inbox. Thank you for bringing the best parts of the internet to my feeds on X, Bluesky, and Mastodon.

Thanks. With your continued help, I can [probably] become a better writer, and [maybe] a better thinker.

Serialized scrapscript expressions are called "flat scraps".

In a previous essay, I crammed scrapscript into MessagePack.

At the time, I didn't realize that Max Bernstein had already written an entire serializer in ~100 LOC. Mind blown!

After further experiments, I somehow convinced myself that this serialization format also needed to (3) commit to existing standards, (4) work overtime as a pseudo-IR, (5), and run on relatively crappy hardware.

I'm still in the discovery phase here. Max's format remains very attractive after witnessing the weight of popular CBOR and msgpack implementations.

Meanwhile, Peter Saxton (EYG) sent me a friendly email recommending CBOR as a potential alternative to MessagePack.

Uh oh -- competing standards? Marginal design tradeoffs? Open-source woes? Buckle up!

Drama is fun, but not relevant to this essay. This post provides a solid summary of CBOR's history. This comment links to the most contentious public spats.

Which is cooler?

Obviously MessagePack is what cool kids would use.

Compare the subheadings on each landing page:

• msgpack: "It's like JSON. but fast and small."
• CBOR: "RFC 8949 Concise Binary Object Representation"

One of these formats is wearing a damn necktie.

Everything about CBOR is uncool. It was designed by a committee. It reeks of RFCs. Acronyms are lame. Saying "SEE-BORE" is like licking a nickel. One of the authors is "Carsten Bormann", which makes the name feel masturbatory.

CBOR was inspired by MessagePack. MessagePack was developed and promoted by Sadayuki Furuhashi ("frsyuki").

-- RFC 8949

Loyalty to an "original" brand has merit. Instead of chasing mere incremental improvements, you can support creators who synthesize value from nearly nothing. To favor derivative work can feel like choosing bureaucracy over personal expression.

Which is more efficient?

But many people don't care about "coolness" -- they want compression and speed and performance.

In these benchmarks, the author compared performance between two popular Go libraries. From these tests, it appears that the CBOR library encodes/decodes ~200% faster.

Which is simpler?

But efficiency isn't everything. I usually choose conceptual simplicity over performance. Like most makers, I resent depending on forces I cannot understand.

To measure complexity, you can often use documentation length as a proxy. MessagePack is just a markdown file. The CBOR spec has its own gravitational field.

However, upon further scrutiny, I've found that the documentation sniff-test misled me. This HN comment shares my latest thoughts:

Yeah, I skipped all the drama, read the spec and implemented an encoder/decoder. CBOR is just how MessagePack-like format should have been done from the beginning: it's technically superior in a sense that it's neat and simple, replacing many specialized rules with one generalization.

At its top-level, MessagePack defines a bunch of types: integers, floats, arrays, extensions, etc. CBOR unifies these types with "tags"; this pattern seems much easier to explain and implement.

This person posits that CBOR's tags are poorly designed. Although I respectfully disagree with his conclusions, I think he makes some great points.

Which is more popular?

"Serialization" often connotes "communication". Bandwidth is expensive, so formats like MessagePack and CBOR make obvious candidates for computer protocols.

Metcalfe's Law states that the value of a protocol is proportional to its popularity.

The data speak for itself:

Which is better?

For my particular use-case, CBOR totally wins. Scrapscript expressions feel great inside CBOR's extension tags.

I prefer CBOR, but I don't like that I prefer CBOR. It irks me to use technology with political baggage.

Anyway, MessagePack and CBOR are vast improvements over JSON. As long as MessagePack retains its popular advantage, both options seem reasonable.

Protocols are important. Communicate with caution.

They taught you to make number go up. They said that obedient kids get good grades, that productive people get paid, that the wealthy are powerful and free and attractive and happy.

But life doesn't always provide obvious numbers. You had GPA but graduated. You had ELO but got a job. You had KPIs but took vacation. You had matches but got married. You had salary but got laid off. You had citations but created a human. You had BMI but got diagnosed. You had numbers but you changed.

They baked "number go up" into your traditions, beliefs, cultural norms, media, milieu, etc. They programmed you to make number go up, and it's difficult/dangerous to edit that stubborn firmware. People who venture beyond their prescribed structures (e.g. school, work) often feel anxious and worthless.

So maybe you need a number to strive, to thrive, to win. That's okay. You may need that number to synthesize structure for what to do, how to live, who to become.

LGPA is a number. When you are aimless and/or despondent, you can make this number go up. It won't guarantee happiness, but it can incentivize some of its correlates:

LGPA =
  ln(♡) * log10($) * log[3/2](☺)
    + sum(lgpa(child[i]) / 4)

♡ = volunteer hours
$ = net worth
☺ = fitness percentile

Some non-obvious beliefs are encoded into LGPA:

• Balanced: The LGPA formula punishes min-maxing, i.e. LGPA is zero if fitness or wealth or volunteering are zero.
• Curved: In this formula, each variable adds diminishing returns, e.g. growing $10K into $100K is as valuable as $10M into $100M.
• Sharable: Couples/families can use shared LGPA to strategize specialized roles, e.g. LGPA(Alice+Bob) ≥ LGPA(Alice)+LGPA(Bob).
• Domestic: Many definitions of "success" are blind to domestic labor. Good parents should feel like valuable contributors to society.
• Independent: Parents shouldn't fulfill dreams/goals through children. In this formula, parents are incentivized to pursue personal growth.
• Responsible: Your life is not fungible. Spending money on charity cannot be exchanged for spending time on charity.
• Accomodating: The definitions of "fitness" and "volunteering" are purposefully vague enough to accomodate many worldviews/beliefs. Two reasonable respective starting-points: age-adjusted VO2-Max percentile and unprofitable hours spent on strangers.
• Economic: This formula assumes that most dollars are earned via positive-sum interactions. If true, net worth is a crude measure for the amount of value one has created for other people. "Cumulative non-inherited net worth" might be a more appropriate variable for LGPA.

They taught you to make number go up -- don't play by their rules. You needn't feed your organs into a vending machine. You can pursue your own number; you can use that number to synthesize structure.

One day, you might build your stable structure far from those institutions. Revel in your success -- your health, your abundance, your compassion. With enough distance, you'll forget you ever wanted to be a number.

I'm literally dying 💀

In contemporary English, the world "literally" means both "literally" and "figuratively". It's one of the few words that can be used (without irony) as its original meaning and its opposite.

Likewise, "sorry" now conveys conflicting messages. Its etymology hints that "sore" (e.g. "look at that sorry clown") merged with unrelated "sorrow" (e.g. "the clown is sorry for the terrorist attack") and morphed into an apology (e.g. "I'm sorry for the clown").

Apparently, to be "sorry about" something was popularized by Get Smart (e.g. "sorry about that, Chief"). It's remarkable how unfunny the show is by today's standards.

Because "sorry" encompasses outer ("sore") pain and inner ("sorrow") pain, it's a popular word to express sympathy/empathy. But "sorry" can also be an apology -- an expression of fault.

The problem here is that "sorry" both conveys sympathy without fault and sympathy with fault, i.e. "I'm sorry your feelings were hurt" vs. "I'm sorry I hurt your feelings".

To make things more confusing, "sorry-not-sorry" expresses unsympathy with fault.

I no longer trust this word, so here are some alternatives that I'm trying to adopt:

• that's unfortunate: I am expressing sympathy for your pain
• I feel you: I am expressing empathy with your pain
• whoops: one of us made a mistake and I'm open to peaceful resolution
• thank you: I inconvenienced you and I appreciate your grace
• I apologize: I harmed you, I don't excuse it, I've taken steps to change, and I want to repair the damage

My parakeet lost its eye-patch again.

How unfortunate…

The burrito disintegrated while I was driving.

I feel you.

Why is there a cowboy hat in the freezer?

Whoops!

What took you so long?

Thank you so much for your patience -- I had an unexpected fecal event.

You killed my turtle!

Yeah, my bad. I shouldn't have let it eat that entire calzone. To prevent this from happening again, I registered for a 10-week course on animal nutrition. Augustus was irreplacable, but if you'd like, I can help you adopt two new turtles named Barbara and Carol.

I want nushell plus notebook UI. Or maybe jupyter notebooks minus UI?

It's more than a terminal, but less than a desktop environment.

Give me tiny lil' apps for email, calendar, RSS, streaming, editing, etc.

I want DWIM semantics… without sacrificing type-safety.

Let me pipe graphical programs together like DAW plugins -- knobs optional, please.

An Intuition

Here's what this dream might look like in bash:

$ curl "names.json" | nano | jq '.[].name' > names.txt

   100% ■■■■■■■■■■■■■

   [{"name":"Alice"},{"name":"Bob"}]

   ˟ "Alice"
   ˟ "Bob"
   + ﹍﹍﹍﹍

   ⎋ names.txt :: 8kb :: 10μs :: 15 seconds ago

In this example, I'd want the JSON displayed by nano to work like a live textarea. Upstream edits would propagate through the pipes:

$ curl "names.json" | nano | jq '.[].name' > names.txt

   100% ■■■■■■■■■■■■■

   [{"name":"Blice"},{"name":"Bob"}]

   ˟ "Blice"
   ˟ "Bob"
   + ﹍﹍﹍﹍

   ⎋ names.txt :: 8kb :: 7μs :: just now

A Mockup

This paradigms extends the UNIX pipe metaphor with pipe gauges.

The magic here is that each gauge is interactive. By manipulating a gauge, you can synthesize/manipulate its pipe.

A Reveal

And to nobody's surprise -- scrapscript is the hammer that transforms my problems into nails.

Here's how the same command might look in smel, a scrapscript shell:

http "names.json" []
|> edit []
|> each (get "name")
|> write "names.txt" []

Empty lists can behave like typesafe --flag=value params:

http "names.json" [#method #get, #json]
|> edit [#vi]
|> each (get "name")
|> write "names.txt" []

An Example

But what's going on inside the pipes and gauges?

Let's imagine a simple progress widget inspired by Elm Architecture:

http "names.json" []
|> smel/widget
   { init = { count = 0 }
   , subs =
      model -> [ end #end, key "q" #end, in #out ]
   , update =
       {count} ->
         | #out #nothing -> {count} ' cmd/out out
         | #out (#package x) -> { count = x.content-length } ' cmd/out out
         | #out (#packet x) -> { count = count + bytes/length x } ' cmd/out out
         | #out (#text x) -> { count = text/length x } ' cmd/out out
         | #out (#affix x) -> { count = count + text/length x } ' cmd/out out
         | #out (#row x) -> { count = count + 1 } ' cmd/out out
         | #out (#blob x) -> { count = bytes/length x } ' cmd/out out
         | #out (#chunk x) -> { count = count + bytes/length x } ' cmd/out out
         | #out (#list x) -> { count = count + list/length x } ' cmd/out out
         | #out (#item x) -> { count = count + 1 } ' cmd/out out
         | #out _ -> model ' cmd/err "unexpected input"
         | #end -> model ' cmd/end
   , view = {count} ->
       smel/ui/rows
       [ smel/ui/text [] "PROGRESS"
       , smel/ui/text []
         (text/from-int count ++ " " ++ text/repeat count ".")
       ]
   }
|> edit []
|> each (get "name")
|> write "names.txt" []

-- PROGRESS
-- 33 .................................

Without going into too many details:

• Incoming data/signals flow into subs. These subscriptions pass messages (e.g. #out _) to update.
• This widget can receive lots of different types of data via in. When it receives "complete" data (e.g. #list _), it overwrites count. When it receives incremental data (e.g. #item _), it increments count accordingly.
• When count is updated, the view is automatically re-rendered.
• smel/ui is a minimal UI library that can target terminal, browser, etc.

A Dream

This architecture can yield lots of cool interactive notebook-like widgets!

A Seed

Here's how I currently imagine the smel platform API for building widgets:

{widget,sub,cmd,err,act,pipe,ui}

. widget : model => msg =>
    { init : model
    , subs : model -> list (sub msg)
    , update : model -> msg -> model ' cmd msg
    , view : model -> ui msg
    }

. sub : msg =>
    #end msg
    #in (stuff -> msg)
    #key (byte -> act -> msg)
    #touch (point -> act -> msg)
    #every { ms : int, do : time -> msg }

. cmd : msg =>
    #none
    #end
    #err text
    #out stuff
    #batch (list (cmd msg))

. act :
    #up
    #down
    #press

. stuff :
    #nothing
    #scrap scrap
     #sliver bytes
    #text text
     #affix text
    #table (dict text (list scrap))
     #row (dict text scrap)
    #package bytes
     #packet bytes
    #blob bytes
     #chunk bytes
    #list (list scrap)
     #item scrap

. ui : msg =>
    #text { wrap : bool, data : text, ..style }
    #cols { data : list ui, ..style }
    #rows { data : list ui, ..style }
    #tip { label : text, data : ui, ..style }
    #button { click : msg, label : text, ..style }
    #input { input : text -> msg, label : text, ..style }
    #progress { label : text, count : float, total : float, ..style }

. style :
    { align : #left #center #stretch #right
    , border : #none #solid
    , border-color : #inherit #color color
    , font-color : #inherit #color color
    , font-size : #title #subtitle #body #note
    , font-style : #unstyled #bold #italic #strike #underline
    }

An Invitation

If this vision of personal computing excites you, please contribute:

• add comments/questions/suggestions to my PR in surprisetalk/smel
• add to Max Bernstein's beautiful implementation at tekknolagi/scrapscript
• keep an eye out for the self-hosted draft spec at scrapscript/scrapscript

If you don't already have what you need, go find it! I don't know where it is.

And if you don't know where to look, maybe try asking better questions?

When all questions elude you, you're already there.

Why don't you like it there?

It's okay. It's okay. You're alive. You have what you need.

Dad: You're too smart to be a cashier forever — you should start thinking about your future.

Manager: I know you're already working overtime, but we need the project done even sooner than expected.

Aunt: You're so pretty - why do you always hide behind those glasses?

Friend: I'm just being honest because I care - you'll never get married unless you lower your standards.

Coworker: Your English is improving, but honestly, it's still really hard to understand you sometimes.

Neighbor: Is everything okay? Your yard looks more unkempt than usual.

Acquaintance: Most new moms struggle to balance work and family, but you seem totally fine with leaving your kids in daycare all day.

Unsolicited criticism traps us in tricky situations.

Most people cast themselves as heroes: they see your struggle, they want to help, and they have a solution for you. Unfortunately, this usually foists the difficult work onto you.

Charitable interpretations strengthen relationships. Life is easiest when everybody everywhere is automatically your friend.

Assuming those best intentions, most suggestions stink because they're not actionable. They believe you lack awareness rather than resources.

Quickly and kindly correct the category error. Recognize their generous sympathy and ask for concrete support.

Don't try to prove a point. Passive-aggression (and active-aggression) will turn your eager allies into enemies. Clearly state facts; sincerely ask for help.

Uncle: With your brain, you could make so much more money if you just worked in finance instead of teaching.

You: I don't always feel so smart, but thanks for taking an interest in my career. I appreciate the candor. How do you want to help?

Grandma You'd be such a catch if you just lost a few pounds!

You: Yep, I often feel fat and unlovable. What kind of help are you offering?

Mom: You work so much! I'm worried about your health.

You: Yeah, it actually sucks sacrificing my youth for paltry wages. Thanks for recognizing that. I hate what my life has become and I dread the future. How would you like to help?

I recently stumbled upon a well-written (but outdated) overview of the base SI units from Theodore Wildi's Electrical Machine Drives and Power Systems.

I heard about the 2019 changes to these definitions, but I totally missed the elegance of the new model:

Dependence of base unit definitions on physical constants with fixed numerical values and on other base units that are derived from the same set of constants.

Each of our SI units now roughly derives from a fundamental constant! Neat!

Apparently the definition of "fundamental constant" is itself a bit wishy-washy, but Uzan's summary seems tidy:

• the gravitational constant G
• the speed of light c
• the Planck constant h
• the 9 Yukawa couplings for the quarks and leptons (equivalent to specifying the rest mass of these elementary particles)
• 2 parameters of the Higgs field potential
• 4 parameters for the quark mixing matrix
• 3 coupling constants for the gauge groups > SU(3) × SU(2) × U(1) (or equivalently, two coupling constants and the Weinberg angle)
• a phase for the quantum chromodynamics vacuum

Anyway, I love this universe:
