These are the articles that you might have to read first to be able to better understand some of the more complex ones. I'll try to post a link at the top of any "advanced"articles to remind you to read whatever, but here they are in case I forget.
In this series of articles (which will be written at random times), I'll explain the basic premises of whatever I can think of. They generally are written when I'm writing an article and find that I'm spending way too much space explaining certain concepts, and so I turn that into a post of its own.
Here we go.
