I read and learn stuff for fun these days, both theoretical and practical. I read quite often, but in small chunks. I tend to find that, even after reading only a page of a decent book on something, many interesting ideas are motivated. The purpose of this wiki is to act as a dumping ground. I do not vouch for the correctness of any of the thinking here: it is dumped in a reasonably raw form, but in such a way that I can find it later, others can see things as they grow, and I can refer others to the thinking by simply posting a link.
