My Language Ranking Based on Coolness

admin — Wed, 19 Oct 2016 13:31:03 +0000

With so many sites measuring programming language popularity, here’s the coolness, not popularity ranking of languages ranking by me. This is my PERSONAL opinion.

1. Ruby – need I say more?
2. Objective-C
3. Go
4. C, not C++
5. Coffeescript – yes, I said it, ok?
6. Haskell
7. R
8. Swift

Install Ruby 2.3.1 from Source on Ubuntu 16.04

admin — Fri, 09 Sep 2016 18:21:05 +0000

Execute this as the root user. If not, you can always add sudo. Here’s the script:

#!/bin/bash


set -e
apt-get update

apt-get install -y curl build-essential libreadline-dev \

                   libffi-dev zlib1g-dev openssl vim \

                   libncurses5-dev libcurl4-openssl-dev \

                   libgdbm-dev libqdbm-dev libssl-dev

apt-get autoremove && apt-get autoclean

curl -O https://cache.ruby-lang.org/pub/ruby/2.3/ruby-2.3.1.tar.gz

tar xvzf ruby-2.3.1.tar.gz

cd ruby-2.3.1

./configure

make && make install

cd ..

rm -rf ruby-2.3.1*

echo "gem: --no-ri --no-rdoc

install: --no-ri --no-rdoc

update: --no-ri --no-rdoc" > /usr/local/etc/gemrc

gem install bundler pry interactive_editor

Setting Up a React Project

Simple Web Server with Ruby or Python

admin — Sat, 30 Apr 2016 20:59:21 +0000

I was developing a Javascript app and wanted to run a web server pointing to current directory.

Using Ruby

A simple script to start a WEBrick server. You can modify the root directory to a subfolder if you’d like. I named this script “server” with chmod +x so I can run it with ./server
#!/usr/bin/env ruby

require 'webrick'

server = WEBrick::HTTPServer.new(Port: 8000, DocumentRoot: ".") Signal.trap('INT') { server.shutdown } server.start
Python

A simple command using python -m SimpleHTTPServer
