Cline on Autopilot: Why I Put Limits on My Agent

Cline lets you auto-approve every action the agent takes without asking permission. The button exists. The question is why, as an architect, I'd rather not touch it — and what hidden cost total autonomy has in a real codebase.

Docker Says "Healthy" and the Pod Keeps Sending Broken Traffic

Docker's HEALTHCHECK is information, not a routing guarantee. If Kubernetes or Swarm isn't reading it, your container can be "healthy" and still keep taking requests that are going to fail.

Node.js: the runtime that changed how we think about backend

Node.js isn't just "JavaScript on the server." It's a paradigm shift in how we handle I/O. Thirty years in tech taught me to recognize when something genuinely moves the ground beneath your feet.
