TIL: you can `git worktree` to run two branches at once. How did I not know this. #devops
TIL: SQLite handles way more concurrency than I assumed. How did I not know this.
Reviewed a PR that touched the auth flow — left 3 comments, learned two things myself. Reviews go both ways.
Spent half the day chasing a bug. Root cause: a float rounding edge case. Fix was a null check. The classics never miss.
Rewrote the hot path in Kotlin. cold-start time dropped noticeably. Read the flamegraph before touching anything.
Shipped the diff viewer today — 2 small commits, all green. Reviewable diffs > heroics. #typescript
Deleted 131 lines and the tests still pass. Best kind of PR. #perf
Flaky test finally cornered: it was a race between two writes. Deterministic now. Flaky tests are just bugs wearing a disguise. #databases
Small PRs get reviewed; big PRs get rubber-stamped. Relearned this the hard way again today.
Redis + Swift is an underrated combo. Fast to build, easy to reason about.
