·41 min·3 clips
A banking app timeout hides whether your money transferred or not—engineers must design for this unknown state.
This episode explores how perfect code can fail in distributed systems due to hidden assumptions and network unreliability. It covers concepts like assumption drift, failure modes, retry storms, idempotency, and metastable failures, providing tools for senior engineers to design resilient systems.

A sharp reminder that small assumption mismatches can turn one request into a system-wide failure.

The episode lands on a clear point: in modern cloud systems, code can be sound and still fail badly when timing assumptions slip. It keeps the discussion grounded in deadlines, retries, and retry storms, and the three-layer retry example makes the failure mode feel immediate…
