Welcome to Leo's Notes

A collection of random notes on various topics.
This is mostly for my own personal use, but if you see a flagrant error (which isn't entirely impossible!) let me know.

This is Leo's personal Wiki. It's a place where I document things I'm using, working on, or trying to learn. As you might be aware already, the content is heavy on technical computer stuff from the lens of a systems operator with some random bits sprinkled here and there.
