I write code for a living, but only when it is fun. Geek, techie, pedant, cycle, walk, run an ISP. I even design router/firewalls from scratch. Canon over Nikon, Picard over Kirk. Stargate fan. Yes that picture is me, in a Panama hat, on the Panama canal.

I use a lot of open source, and so does my company, so this is a chance for me to give something back.

There are all sorts of libraries and tools here, from making QR codes, to constructing CO2 monitors from an ESP32.
