I thought that, but then I realised that people here, although all* hackers, have vastly different experience. I'm regularly seeing stuff that I think is old and obvious, and it's getting hugely upmodded, so I thought I'd share this "oldie but goodie". It's very entertaining, even though it is old.
* for some definition of "all".
Well, I appreciate it. I was 9 years old and had no idea.
