If you don't know about the JargonFile (a.k.a. NewHackersDictionary) yet, follow these links only if you have two to four days of free time. It's maintained by the ever net.busy EricRaymond.
The original version is here: http://www.dourish.com/goodies/jargon.html
An audio French jargon file is also available here:

Theres also a Jargon Wiki, which has based many of its articles off the Jargon File 4.4.7.
