I hack in Rust, Scheme, Emacs Lisp & C++. I write about that here. I recently started a public inbox at sourcehut, which I use for discussion of those writings.

I maintain an MP3 tagging project called scribbu, whose source distributions may be found on my distributions page. I also wrote an Emacs package for scoring Elfeed entries: elfeed-score. It's available at MELPA, but you can download source tarballs there as well. You can also find Guile Scheme bindings for libmagic there.
