Stay up to date with practical insights on backend engineering, system design, and building reliable software.
The CAP Theorem gets rehearsed for system design interviews and then forgotten. That is a mistake — the tradeoffs it describes show up in every distributed system you build or operate.
Read moreMost teams install a CI/CD tool and call it done. But running a pipeline is not the same as practicing continuous delivery — and confusing the two is why deployments are still painful.
