Notes from the systems I actually run.

I’m Michael. This is my working notebook for Linux, infrastructure, networking, virtualization, security, and the occasional useful command.

Most of these posts begin as the answer to a problem I expect to encounter again. I write down enough context to make the solution useful later—for me, and hopefully for anyone else who lands here.

The site is intentionally small and static. The projects are open source, the articles are practical, and the archive stays online even when the technology in it becomes historical.
