I found this pretty amusing.
Years ago, a partner of mine wrote a very simple BASIC program he called Kneel.
10 GOTO 10
He ran it on a client’s DEC VAX (with admin privilege) and it brought the machine to its figurative knees. In fact, the machine operators had to cycle power on the VAX to recover. That was sort of a big deal because it was a time-share system and all its users were locked out of the system until it had been restarted.
I’m guessing he was pretty bored that day.
