Knowledge Base
A growing collection of notes on topics I find interesting or useful. Linux internals, security hardening, networking, infrastructure, and whatever else I happen to be digging into. Some are polished references, others are working notes still being refined from my personal knowledge base. These notes are less curated than my posts and were at least accurate at the time of writing. Some have gotten quite old and while I periodically try to prune or update them, your mileage may vary.
