Tangential: I highly recommend exploring the parent site https://wiki.xxiivv.com and the associated http://100r.co the author is working on with their sailing boat partner. Yes, they're living on a sail boat in the Pacific Ocean.

Some cool software they've developed:

- http://100r.co/site/ronin.html

- http://100r.co/site/uxn.html

It's such a deep rabbit hole of talent, passion and intellectual gratification. I'm not affiliated, just a fan, I really love their stuff.
