This document explains how I would implement an SSA-based compiler if I was writing one today.

This document is intentionally opinionated. It just tells you how I would do it. This document is intended for anyone who has read about SSA and understands the concept, but is confused about how exactly to put it into practice. If you're that person, then I'm here to show you a way to do it that works well for me. If you're looking for a review of other ways to do it, I recommend this post.

My approach works well when implementing the compiler in any language that easily permits cyclic mutable data structures. I know from experience that it'll work great in C++, C#, or Java. The memory management of this approach is simple (and I'll explain it), so you won't have to stress about use after frees.

I like my approach because it leads to an ergonomic API by minimizing the amount of special cases you have to worry about. Most of the compiler is analyses and transformations ov

Cryptography

https://github.com/spieglt/cloaker - password-based file encryptor (NOTE: uses Qt)
https://github.com/str4d/rage - file encryption tool and librarary that uses the age format

Media

https://github.com/mohanson/gameboy - gameboy emulator
https://github.com/bartwillems/lyriek - fetch the lyrics of a song playing in an mpris-compatible player
https://github.com/JakeStanger/mpd-discord-rpc - discordrpc for mpd

Module Workers Polyfill

This is a 1.1kb polyfill for Module Workers.

It adds support for new Worker('..',{type:'module'}) to all modern browsers (those that support fetch).

Usage

Copy module-workers-polyfill.js to your web directory, then load it using an import or a script tag. It just needs to be loaded before instantiating your Worker.

Boot Sector Games

A list of playable boot sector games, most of which are on github. Fun to play, great to learn from. There are also many cool non-booting boot sectors out there that aren't games (so more like demos), but this page is just reserved to interactive boot sectors / games. This list is also not complete, but not on purpose, it is a best effort collection of games, so if you know of any fun boot sector games, please contribute.

This page lists a collection of 31 games spanning several authors: nanochess, me, daniel-e, shikhin, JulianSlzr, XanClic, QiZD90, darkvoxels, guyhill, w-shackleton, egtzori, VileR, ish_works, franeklubi, queso_fuego, franeklubi, Jethro82, waternine9, tevoran, palma3k, taylor-hartman. peterferrie should also be mentioned as he has touched a lot of these games.

TetrOS

Tetris Clone. Full color, no score. This was one of the older boot sector games out there. ![tetros](https://gist.github.com/assets/1570856/3a0d1023-cbe6-4b4d-
