machinageist
I run a small homelab and write about the networking, Linux, and operations work that comes out of it: DNS troubleshooting, network segmentation, Linux services, and safer change and rollback practices.
Lately
- Testing safer change and rollback patterns for virtualized systems.
- Writing practical notes about DNS, segmentation, and Linux services.
- Maintaining this site as a small self-hosted Rust application.

Solarpunk Is an Operations Question
Early notes on what solarpunk might mean for small systems: repair, legibility, local knowledge, honest limits, and infrastructure people can actually tend.

Security Headers on machinageist.dev
The HTTP response headers this site sets — what each does, the real curl -I output, where they come from in the code, and the honest limits of header hardening on a personal site.
What’s here
- About — Who I am, what I actually operate, and what each claim is backed by.
- Portfolio — Finished work, with evidence. Deliberately short.
- Labs — What I plan to build next in the homelab, each with a step-by-step plan you could follow.
- Writing — Writeups of work on the lab, including the outages.
- Learn — A public education wiki on networking and Linux, built from my own study notes and checked against the primary sources.
- Study — Practice questions and scenarios drawn from the wiki, with an explanation and a link to the page behind every answer.
- Glossary — Terms and commands from the wiki, each linked back to the page that explains it.
- Search — Full-text search across the writing and the wiki.
- Status — Live uptime and request counts for this server.
