This is the technical blog for Razortooth Communications. Expect write-ups from live projects: sizing local inference hardware, threat modeling medical devices, over-the-air update designs that survive a bad image, and moving fleets of ARM devices onto NixOS.

Posts will be tagged to the service they came out of, so if an article describes a problem you have, the offer that solves it is one click away.
