Thirty-nine posts and a hundred and eleven tags. The tags are a good index and a bad front door, so these six are the front door. A post can appear under more than one.
Topics
Six ways into the archive — networking, security, AI agents, observability, Linux, and the things I built.
Networking
Firewalls, VLANs, DNS, tunnels, and the reverse proxy in front of all of it.
Security
Hardening, vulnerability scanning, identity and MFA — including the audits that found things.
AI & agents
Claude Code, Codex and Kimi working on the lab, the gateway in front of them, and the controls around them.
Observability
Metrics, logs, traces and alerts — and the difference between having them and being monitored.
Linux & Docker
Debian, systemd, containers, backups and the scheduled jobs that keep the host alive.
Things I built
Apps, scripts, dashboards and mods — the projects rather than the infrastructure.
