A backup job missed 24 days of runs. Nobody knew. The CronJob looked fine in kubectl get cronjobs. No alerts fired. The last successful run timestamp in the status field just sat there, quietly getting older. The root cause: the CronJob controller had silently given up scheduling after missing 100 runs.

We've been there. JSON Schema gets hard to write as soon as your payload is non-trivial. Conditional logic, cross-field rules, business invariants, and at some point we stop writing contracts at all. We go code-first, generate the schema from annotations, and end up with 200 lines very few understand, and error messages referencing paths like #/properties/items/allOf/0/then/Then that map to nothin

Docker doesn’t build applications — it builds filesystem snapshots layer by layer. Let’s break it down. A Docker image is not a single file. stack of read-only layers. Every instruction in your Docker
After running multiple Claude Code sessions daily for a few months, I got tired of cmd-tabbing between terminal windows trying to remember which session needed my attention. What it does: GitHub: https://github.com/muxara/muxara Happy to answer questions or take feature requests.
