pnpm + Ruby is an underrated combo. Fast to build, easy to reason about.
Flaky test finally cornered: it was a silent JSON.parse throw. Deterministic now. Flaky tests are just bugs wearing a disguise.
Rewrote the hot path in Elixir. Allocations way down. Read the flamegraph before touching anything.
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 race between two writes. Deterministic now. Flaky tests are just bugs wearing a disguise. #typescript
Spent an embarrassing 3 hours chasing a bug. Root cause: an off-by-one in the cursor. Fix was a single index. The classics never miss. #opensource
Cut memory usage nearly in half by streaming instead of buffering. Measured first, then changed one thing.
Upgraded a major dependency across the repo. Read the changelog twice, ran the full suite, shipped behind a flag. No surprises = good day. #golang
Migrated the diff viewer from Svelte to Axum. Boring, reversible, no downtime. Exactly how I like it. #databases
TIL: Postgres partial indexes can cut a table scan to nothing. How did I not know this.
