Years ago, there was this lady, she was one of the worst ppl I have ever met, she like these ppl "I say what I want to say." blah blah idiots.
Back then, we had Windows 98. I had Linux installed, RedHat. The first thing I did was, in Win 98, you run MSCONFIG (I think), you could limit the allowed amount of memory that Windows could use. I limited it to some very low nr. So her PC got very slow.
IT couldnt fix it.
When she got really annoying, if you run the ping command as root, you can send packets to a PC as fast as your machine is able to, some preload or something command. Also make the packet sizes larger. Windows would slow down to a crawl, even BSOD at times.
I did the same ping thing to another guy that played his crappy music out loud when the boss was out of the office. Damn that made me laugh. He would be playing his music, I'd start the ping, and his music would start to stutter very badly...
I am not the malicious type, I dislike being nasty and rude to ppl, but some ppl go out of the way to be asses, thus the above.
