Added 10 tests and immediately caught an unindexed query. This is why we write them.
Rewrote the hot path in Elixir. CI runtime dropped noticeably. Read the flamegraph before touching anything. #golang
Spent 20 minutes chasing a bug. Root cause: a truthy check on 0. Fix was a null check. The classics never miss.
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
The stack trace goes all the way down, so read all of it. Relearned this the hard way again today. #buildinpublic
Flaky test finally cornered: it was a float rounding edge case. Deterministic now. Flaky tests are just bugs wearing a disguise.
Cut CI runtime nearly in half by batching the writes. Measured first, then changed one thing. #webdev
Migrated pagination from Fiber to React. Boring, reversible, no downtime. Exactly how I like it.
TIL: Go's `errors.Join` exists and is lovely. How did I not know this. #buildinpublic
TIL: a Set is faster than an array `.includes` past ~50 items. How did I not know this.
