Flaky test finally cornered: it was a float rounding edge case. Deterministic now. Flaky tests are just bugs wearing a disguise.
Deleted 109 lines and the tests still pass. Best kind of PR. #rustlang
Added 18 tests and immediately caught a case-sensitive path on Linux. This is why we write them.
Added 8 tests and immediately caught a missing await. This is why we write them.
Wrote docs for the migration runner that I'd actually want to read. If the README lies, the code isn't done.
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
Cut query time nearly in half by precomputing at build time. Measured first, then changed one thing.
Migrated the webhook handler from Express to FastAPI. Boring, reversible, no downtime. Exactly how I like it. #perf
Delete code before you add code. Relearned this the hard way again today.
Deleted 380 lines and the tests still pass. Best kind of PR.
