Ah, the biggest troll on Usenet once again shows just how stoopid he is.
He refuses to use his real name because he doesn't want everyone to
know he's neither a programmer or the electrical engineer he claims to
be. He's made that all too obvious so many times.

No, he's just a ditch digger who got fired because he couldn't figure
out which end of the shovel to use.
