My repositories (including some notes) are at git.aberrantflux.xyz. I also have some stuff at github.com/kaistevenson. The repo for this site is git.aberrantflux.xyz/aberrantflux-site.git if you want to get a little meta. I use cgit to serve my repositories over HTTP, and otherwise use SSH.
I have a few particularly cool projects, like Precedent, my interpreted programming language, and Snake3, a fun snake game. If you want to contribute to any of my repositories, just email me with a diff and a brief description of your changes. If I like your commit, I'll integrate it.
