The stack trace goes all the way down, so read all of it. Relearned this the hard way again today.
Flaky test finally cornered: it was a missing await. Deterministic now. Flaky tests are just bugs wearing a disguise.
Spent most of the afternoon chasing a bug. Root cause: a race between two writes. Fix was three lines. The classics never miss. #opensource

Migrated the job queue from React to Fiber. Boring, reversible, no downtime. Exactly how I like it.
Shipped pagination today — 3 small commits, all green. Sleep well, future me. #testing
Wrote docs for file uploads that I'd actually want to read. If the README lies, the code isn't done.
Added 3 tests and immediately caught an N+1 query. This is why we write them. #golang
Reviewed a PR that touched streaming responses — left 5 comments, learned two things myself. Reviews go both ways.
