The Daily WTF is a blog of embarrassing and unfortunate pieces of computer code. "WTF" used to mean "What The Fuck" but now, apparently, means "Worse Than Failure"; I think I prefer the old definition.
Now, that's all well and good. The problem comes when people start commenting. You see, most of the people leaving comments, well, aren't the smartest. Worryingly, in comments on this article, most of them don't seem to know what a hash table is. This is pretty basic stuff, for someone who works as a programmer, and it is not reassuring to know that there are this many clueless people about. Even better, really, is the self-righteousness with which they air their very, very wrong ideas about what a hash table is.
The software that the site runs on, incidentally, is another "WTF". It uses a horrific forum tool called Community Server, written in .NET. It isn't quite as bad as it used to be, but for a couple of years, attempting to make a post using anything but IE 6 would cause catastrophe.
