All sorts of things end up here, often before they are posted to my Web site. Whilst most of this is just rough notes, you're welcome to browse it. At first, this wiki was just my brain dump, but now several different authors create pages here.
If you find a mistake, want to comment on anything, contribute or even just ask a question, please get in touch. I used to allow anyone to directly edit this wiki, but constant attack by wiki-spamming bots were spoiling it. If you'd like an account for any reason, just ask.
Who knows, maybe you found something useful here? If you'd like to buy me a pint, send bitcoin to 19z77ozVteA2jtR87Mz9Gbtt86xfSogpfF
