If you want to discover some even more obscure UNIX, SDF is having its Plan9 boot camp this Sunday. You can register now to get an access to their public access Plan9 machine at sdf.org/plan9

Nice! Gemtext and gemini in general is a really cool playground. I also learnt awk to do my gem2web script and all this lead me to web hosting. Very nice technology.
