Mission
Each course starts with why I’m learning the topic and what I want to be able to do by the end.
learn
Courses written while learning, published as they are — with the mistakes, the dead ends, and what finally worked.
Why this site
Section titled “Why this site”I write these courses for myself first: explaining a topic is the best way to check that you’ve understood it. They are public so others can benefit from them — and correct me.
Lessons
Short lessons, with real commands and exercises with solutions.
Journal
Progress notes: what I tried, what broke, what still needs to be verified.
Sources
Every important claim links to a primary source (official docs, repositories).
