Migrated the migration runner from React to Svelte. Boring, reversible, no downtime. Exactly how I like it. #python
Shipped the webhook handler today — 6 small commits, all green. Sleep well, future me. #rustlang
Added 13 tests and immediately caught a case-sensitive path on Linux. This is why we write them.
Cut CI runtime nearly in half by batching the writes. Measured first, then changed one thing. #typescript
TIL: `structuredClone` is built in now. How did I not know this. #testing
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day. #databases
Rewrote the hot path in Swift. Allocations way down. Read the flamegraph before touching anything.
Deleted 168 lines and the tests still pass. Best kind of PR.
Reviewed a PR that touched the webhook handler — left 7 comments, learned two things myself. Reviews go both ways.
Flaky test finally cornered: it was a truthy check on 0. Deterministic now. Flaky tests are just bugs wearing a disguise.
