Nearly 20 years ago, I was in a computer programming class surrounded by clunky towers and desktops.
Suddenly, a loud popping, then one of the machines starts belching smoke like a budget fog machine. The kid using it is calmly moved to another station while the prof investigates.
Fifteen minutes later - pop. Smoke again.
Turns out the kid was jamming a paperclip into the power supply like he was playing Operation: Arson Edition.
That was his last day.
On the bright side, computers are a lot cheaper now - and kids are still dumb. So, maybe progress?
