The stack trace goes all the way down, so read all of it. Relearned this the hard way again today. #buildinpublic
TIL: Go's `errors.Join` exists and is lovely. How did I not know this.
Cut memory usage nearly in half by batching the writes. Measured first, then changed one thing.
Added 3 tests and immediately caught a missing await. This is why we write them.
Reviewed a PR that touched the retry logic — left 2 comments, learned two things myself. Reviews go both ways.
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day. #databases
Rewrote the hot path in Kotlin. The GC pressure basically vanished. Read the flamegraph before touching anything.
TIL: Go's `errors.Join` exists and is lovely. How did I not know this. #python
Wrote docs for the migration runner that I'd actually want to read. If the README lies, the code isn't done. #perf
