This just happened to me - I thought I should share :P

your girlfriend no longer sleeps over because your room is illuminated with screens, LEDs and continues to hum even if she unplugs the powerbar attached to the powerbar attached to the powerbar because you have a wireless back up power supply of you own design hidden under manuals, cables and socks that are dirty but not so dirty you cant wear them again.
you pretend to have a girlfriend when online

You see a book "Wine for Dummies" and immediately think of a free Windows API rather than fermented grape juice. When I opened it, I was like "What the . . ." I had completely forgotten that wine was something you drink for about 5 minutes.

It's scary how many of theses apply to me

• Your favorite sport is Tetris.
• You talk to your computer.
• You argue with your computer.
• Your computer has its own phone line.
• You have dreams involving your computer.
• You remember how to use DOS.
• Your home page is longer than your resume.
• You've ever installed Linux.
• You always understand Dilbert.
• You regularly drink Jolt cola.
• You spend more time on the Internet than you do sleeping.
• You've ever been dumped for paying too much attention to your computer.
• Someone mentions foreign language and you think "Cobol".
• You've ever considered getting a tattoo of the "Intel Inside" logo.
• You check your email before you check your answering machine.
• You've ever tried to see how far you can move the mouse without turning off the screen saver. (Don't tell me, I'm the only one that does this)
• You tinker with computers at work all day, and when you finally get off work, you rush home to tinker with your computer.
• You know exactly how much hard drive space you have free, but you don't know your spouse's birthday.

--you write a comprehensive bulleted list of all the conditions that lead you and others to believing you are a geek.
