Welcome to my website! This is where you can find all of my public projects, blog, contact information and more.
My main interest is computer networking. I have written a Rust userspace for one of my home routers, a DynDNS prefix updater for INWX and a reverse proxy for Luanti (formerly Minetest). I started operating AS210360, an IPv6-only AS, in April 2025 and am currently trying to build my own systems programming language.
A curated archive of the first version of this website is available. See Archive for more information.
2026-03-13: The NAT64 gateway at rtr-vsos-zh was malfunctioning from 2026-03-04 to 2026-03-13, causing all services to be IPv6-only during that period. Details
2026-03-04: rtr-vsos-zh has been upgraded to Debian 13 (trixie), causing intentional downtimes and service degradations during the upgrade period from 10:00 to 15:40 CET. The upgrade has now successfully completed, please report any problems you encounter.
2026-02-22: The contact email addresses have been updated to use my real name, along with the PGP keys. Additionally, the main and backup PGP keys have been merged. The old addresses and keys will continue to work for inbound mail. See the Contact page for details.
2025-07-13: cgit is disabled until further notice due to it easily turning into a DoS when under aggressive crawling. Please use the git-daemon instead. Details
2025-05-30: All of my projects are going to be migrated off of GitHub starting today. Details
Matrix is currently unavailable due to the outdated Debian package being incapable of interacting with the database. There is no timeline for restoration.
The following pages were deemed worthy of being republished. They were once part of the very first version of this website. Most of its contents is withheld, mostly for privacy reasons and because the server-side code contains many security vulnerabilities and should not be used as an example. A full copy is kept on cold storage. Version 2 is likely partially lost. Check this page again in a few weeks or months if you're interested.
The pages have been translated to English (except for the source code). All links have either been removed or adjusted to match the new document tree, and the sources have been adapted to work without PHP or logins.
Warning: All pages require JavaScript for their functionality. They will render correctly without it, but you won't be able to interact with them.
