Writing an OS in 1,000 lines.

Envision a future where everyone can read all the code of an educational operating system.

A tiny C header-only risc-v emulator.

The Computer History Simulation Project

An implementation of OpenGL 3.x-ish in clean C

A MS-DOS Creative Coding IDE/platform based on JavaScript

C11 compiler (mirror)

Build a minimal multi-tasking OS kernel for RISC-V from scratch

Simple generic GUI widget toolkit for SDL2
