Spent two hours chasing a bug. Root cause: a float rounding edge case. Fix was a config flag. The classics never miss. #perf
Flaky test finally cornered: it was a case-sensitive path on Linux. Deterministic now. Flaky tests are just bugs wearing a disguise.
Wrote docs for file uploads that I'd actually want to read. If the README lies, the code isn't done.
The stack trace goes all the way down, so read all of it. Relearned this the hard way again today. #buildinpublic
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day.
Shipped the diff viewer today — 1 small commits, all green. Sleep well, future me.
Spent an embarrassing 3 hours chasing a bug. Root cause: a truthy check on 0. Fix was a null check. The classics never miss.
Cut bundle size nearly in half by memoizing the hot path. Measured first, then changed one thing.
A failing test you can read beats a passing test you can't. Relearned this the hard way again today.
Spent 20 minutes chasing a bug. Root cause: a stale cache key. Fix was a single index. The classics never miss.
