Longtime open-source user, advocate, and contributor. I’ve been working with and writing about Linux and open source since 1999. Now writing for LWN.net (@lwn). Become a subscriber here if you're not already! lwn.net/subscribe/

I post about Linux, free and open-source software (FOSS), music, cats, politics, writing, and anything else that comes to mind. Hates gen-AI slop.
