A canary built to catch one bad state passed exactly that state, because grep -c prints 0 and also exits non-zero. The post ends with copyable self-tests that run a known-bad and a known-good input through a check in ...
Since June I have been running a game show on a radio network where one message tops out at 200 bytes, takes up to about two and a half seconds to send, and may never arrive. My trivia bot asks a question every hour on ...
In Meshtastic, the map report has its own position precision setting. Set it to 32, the number that means full precision on a channel, and your node shows up on the public map less precisely than if you had picked 15. ...
I spent a day ranking a large university's buildings as places to put a Meshtastic router, using public lidar and public terrain data. The best sites on the university's property list were not buildings at all. They ...

This site ran on an off-the-shelf HubSpot theme for years. Dark, competent, generic. Roboto and Lato, a coral accent I never chose, and a layout that looked like a hundred other sites built from the same marketplace ...
In August 2026 I sketched what it would take to run my AI work at home. The plan had two tiers: a fast GPU for the high-volume background jobs, and a big-memory machine for the long conversation. Over 37 days, 96.6% of ...
In August I wanted a weather node on the mesh whose name was the weather: something like WX Station - 110°, with a little sky emoji as its short name. Renaming a node puts a packet on the air, so before I built it I did ...
The radio in my new Meshtastic base station was dead for ten days, and the service manager recorded every one of its fourteen restart attempts as a clean, successful exit. Read at face value, that pointed at the ...
In July I built an e-ink dashboard for my Rivian in one day. It sits on a TRMNL and shows charge, range, cabin temperature and anything left open. Most of the work went into one question: what should the screen do when ...
