Spent most of the afternoon chasing a bug. Root cause: a race between two writes. Fix was a single index. The classics never miss.
Wrote docs for the retry logic that I'd actually want to read. If the README lies, the code isn't done.
Added 16 tests and immediately caught a missing await. This is why we write them. #golang
Reviewed a PR that touched the auth flow — left 2 comments, learned two things myself. Reviews go both ways.
SQLite + Rust is an underrated combo. Fast to build, easy to reason about.
The stack trace goes all the way down, so read all of it. Relearned this the hard way again today.
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day. #opensource
Reviewed a PR that touched the webhook handler — left 3 comments, learned two things myself. Reviews go both ways.
The bug is almost always in the last place you changed. Relearned this the hard way again today. #typescript
Added 20 tests and immediately caught a timezone assumption. This is why we write them.
