I’ve coded a lot of stuff, much of which is opensourced and not maintained anymore. Most of the code can currently be found in my repos on GitHUB
The post-quantum cryptography tool, see the little infopage.
Simple decentralized Ethernet VPN that is now being transformed into an ultimate mesh-networking tool.
Modifiable X11 Display manager with a cool GL default skin.
exa scheme interpreter. Tiny scheme implementation in C++. Kindof slow, but highly modifiable and tightly connected with C++ classes and hierarchy, which enables easy embedding in applications.
Proof-of-concept OpenGL NSPlugin for firefox, which got used as a codebase for several other projects.
A game with bunnies and blood. Lots of blood. Inspired by Jump’n‘Bump but singleplayer.
Racing in BASH (!) with ascii graphics and stuff. You have a superfast car and drive it down a highway, trying to stay on the road and avoid crashing into others.
FFT number multiplier. Not really usuable for anything big (unless you desperately wanted to produce scientific data using a bash script), but usuable if you are searching for a tiny FFT implementation to be included into something.
