Now if you want to be REALLY l33t, you have to bookmark this:

The Jargon File has been around forever, and was created by Raphael Finkel at Stanford in 1975, and continues to be revised and updated to this day. You can find copies all over the place. I forget what the actual home of it is, but you can always google up a copy from somewhere. I have a PDF copy, and i think there are copies in MS Help file format, database format, etc.
It is an in-depth lexicon, and interesting enough just to read, imho.
There's also a few other helpful ones.
