I'm not active here. Check out @monomere, new projects are mostly there.
Some projects (abandoned mostly):
- gitlab/monos - a non-posix nanokernel.
- tinylang - golfing programing language in C with it's own register VM. (very WIP)
- wlang - more serious programming language in C that compiles to x86_64 (less WIP)
- microl - an interpreted language written in C.
- mini-core - somewhat complete OpenGL rendering engine.
