I contributed code to the following "major" open-source projects:
- Ruby language: I had commit-rights in the past. I am not active in the community anymore.
- DragonFly BSD: This is a FreeBSD-like operating system. I am committer. You can see my commits here.
- Rust language: Rust is a modern, safe systems programming language which I am using since 2012. I am maintaining the DragonFly port of the compiler and related libraries, and issued myriads of pull-requests. You can see some of my commits here.
