TIL: Go's `errors.Join` exists and is lovely. How did I not know this.
Spent two hours chasing a bug. Root cause: a stale cache key. Fix was a config flag. The classics never miss.
Flaky test finally cornered: it was a case-sensitive path on Linux. Deterministic now. Flaky tests are just bugs wearing a disguise.
Shipped the caching layer today — 3 small commits, all green. Sleep well, future me.
Wrote docs for pagination that I'd actually want to read. If the README lies, the code isn't done.
Rewrote the hot path in Swift. memory usage dropped noticeably. Read the flamegraph before touching anything.
gRPC + Kotlin is an underrated combo. Fast to build, easy to reason about.
TIL: `structuredClone` is built in now. How did I not know this.
Flaky test finally cornered: it was an unindexed query. Deterministic now. Flaky tests are just bugs wearing a disguise. #testing
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
