Threads

Notes and deep-dives on backend & systems, Go, developer tools, and learning in public. Think of each one as a thread you can pull: short ideas and long build logs alike.

Claude routines are cron jobs that can think
A deep, practical guide to Claude routines: cron jobs whose payload is an agent, not a script. What that breaks (determinism, idempotency, retries, overlap), a gallery of routines worth building, and how to harden one so it behaves when nobody is watching.
