Back in my last year in high school (senior year) about a century ago I was playing with some Turbo Pascal programming (fear the pascal!! ) Anyway, we all had our awesome 386 25MHz computers with *gasp* 4 MB of RAM, we were rockin' We could play Doom on these bad boys!! Anyway, our Windows for workgroups (yuck) machines were networked via Novell IPX, file sharing, print sharing, blah blah, you know the routine.
Our file server had a unheard of 2GB HDD in it, wow was this school high tech or what!! Well after learning some pascal coding, we soon got to the juicy stuff like open files for read/write. Now back to the school computers, everyone had usernames and unlimited space on the file server (shared of course) I think we call these profiles nowadays, not sure. Well the computers depended on that one Novell file server for everything like desktop settings, etc. One day during class, I got this bright idea. I'll make a program that just writes junk text to one file over and over and over and over forever. It would even count up how much space it was wasting, pretty clever eh?
Hmm, what would happen if I ran this on the file server, well after an hour it filled up the HDD with a 1.8GB junk file that started to do bad things. After it reached it's max, for some reason it starting writing over other files. Soon the whole server was hosed and when this happened, it killed every workstation in the school (win 3.11 likes to crash alot). Needless to say, no one ever found out I did it until after I graduated and told the teachers. When word got around, the rumors were flying about how I hacked into the school network and took out the computers. Actually that isn't what I intented to do, but oh well I'm a legend in my own mind
