I put Claude, Grok, and GPT-5.6 in a live debate over how a person should design their life.

C.H.A.R.T.E.R. is a fail-closed standard for governing a fleet of AI agents: one small file per agent lists every model, tool, host, and limit it may use, and the loader that runs it is the only door.

The full picture of my agentic coding setup: how I structured a four-agent team, what habits hold it together, and the reasoning behind every decision that survived real use.

From scattered containers to a proper self-hosted setup: hardware choices, the double NAT problem, and VLAN network design — how to build a homelab that actually keeps running.

The rules I actually follow when working with AI agents — where things stand today, and why some of this will change.

A personal content aggregator for YouTube and RSS feeds with no recommendations, no tracking, no algorithm.

GPG has protected sensitive communication for decades.

On closing the gap between intent and output when working with AI agents — and what it means for how we hire, build, and encode our values into the tools we use.
