You know you're a geek when........

...when you have the 'purity' package installed and have run it more than once.

You ARE a GEEK when all you do is... play THE GRID nonstop!!!

Quoted from Indie Games:

"The Grid is the sort of game I haven't played in over 10 years. It is a text-only strategy multiplayer game you play by actually typing in commands and fantasizing you are logged in a BBS. It does feel quite a bit like a boardgame and generally has you capturing squares, building farms, hiring wizards, stealing from your neighbors, inciting revolutions, forming alliances and even attempting to bless everyone, while fighting to gather all the resources a powerful master of the grid would need.

Fun eh? Well, it is, but it sure isn't the simplest game to master and, were it not for some incredibly patient and kind players, I'd still be struggling with it. Not that I'm not struggling now, but, at the very least, I do have a vague idea of what I should be doing and am even forming some sort of strategy I believe. Great times ahead!"

...you dream in assembler code...

Seriously not binary.

Even worse when you disassemble for different processors in your head

....you enter sleep mode after going to bed.

....you see that the time is 13:37 and you realise it is the coolest moment of the day.

....you are not using your own mail client and realise some people still use Incredimail.

....you just facepalmed like captain Picard when reading the word 'incredimail'.

....you saw the facepalm picture of captain Picard in your head when you read about it.

You know you're a (beginning) geek if you are just as enthousiast about Ubuntu, another variant of Ubunut, programming in Python as the teachers, and other student look at you as if you're talking some other foreign language that no-one understands.

You know you are geek when you yell Allons-y to your friends when you are about to go somewhere or do something.....Doctor Who fans will get this ;D
