This website can help you hold a conversation with the resident geek in your office or try to impress your friends. The best place to start would be the online dictionary. Its list of definitions go from the @ sign to "zone", with plenty in between. If you know of something that's not there, go to the Lexicon Builder, and submit your lingo for possible addition to the list. The international country codes lists the codes that come at the end of an e-mail or web address for countries around the world, from .ad for Andorra to .zw for Zimbabwe.
For This Week in Geek, I'm Mark Avery.
