Tech tips and new discoveries
Why the VM holding my OpenTofu state in Postgres is the one machine OpenTofu does not manage, and how Ansible finds the rest from Proxmox tags.
How I build one Debian 13 autoinstall ISO with preseed and xorriso, and give every machine its own user, address and hostname from the Proxmox API.

Notes on a small container I run at home, which gives HTTP access to the Claude CLI, so I can test API clients without an API key.
