Tech Notes
Tech tips and new discoveries
The second step of my homelab automation. One VM holds the OpenTofu state in Postgres and runs Semaphore, OpenTofu creates the machines, Ansible configures them, and the Proxmox tags are the only thing passed between the two.
How I build one Debian 13 installer image for the whole homelab, create a directory storage on Proxmox over the API, and give every machine its own user and network without rebuilding the image.
How I keep a fresh copy of the /infra folder from my offline mirror box on a spare workstation partition, with rsync over ssh, a read only key, and a systemd timer.
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.
Notes on what I added to 8tickers.com over the summer: a dark redesign, a live home page, insider transactions, a richer news feed, and more.
Why B+ trees became the default on-disk index structure for relational databases, and where they do not work well.
