I believe that the funniest thing that I have done computer related
is when I played a joke on my brother(Hardcore Windows.) I set his bios to allow boot from CD. Then every day I would Insert a diffrent Linux distro
one day Fedora,one day slackware,redhat
His actions ranged from "I hate those dam* virius's and this must be a
new service pack? I finally let him in(He hasn't talked to me in 10 years.)

What are some of your's

THE PENGUIN AND THE DEAMON:
Stands against the Window
and its greatest weapon:
Blue screen of Death

This prank involved windows when it was running under a dos environment, (95, etc). An old program called 'nag.exe'. If the command nag me is invoked (provided of course the program is in the same directory), a blue screen would pop-up and in the middle there will be nagging text, and each time the program is run a different saying would come up. I used autoexec.bat (ah, memories), to invoke that program when windows would boot up, and the boot process would be halted when that program would run, until the program is ended, continuing the boot. I thought it was pretty cool.

What is the funniest thing that you have done (computer related)?

Giving variables funny names in shell scripts.

Sorry, that's it.

He must have not been talking to you 8 years before this incident because you said yourself in another post that you've been using Linux for 2 years.

Our university lab is open 24x7.
I friend of mine was a regular student in this lab after 11PM until next morning. Frequently he spend the all night alone.

We setup a computer to start to play a wave file (the mp3 was not invented yet) with strange and frightening sounds. We reach the top when we make a record from Poltergeist movie when the little girl on the other side of TV call her mother...

Our friend is a brave. He figure out what computer was making the sounds, and them what process, and he trace back the joke to us.

yes he is talking to me now
I knew about linux but I didnt start using it as a standalone
os until two years OS

We had a problem with students connecting to MUD servers in one of our labs. So I wrote a small VB program that captured the user's screens, and allowed me to inject keystrokes into their computers. Then, as they connected to the MUD servers and played, I entered random text into their terminals. The results were confusion from other remote players. Name calling, booting, etc. Eventually it got bad enough that the students stopped playing in the lab altogether. Pretty fun stuff.
