By any chance, who knows why software errors are called "Bugs"?

The first electric computers were made mostly of valves. These used to get very hot during operations of the computer so the huge electronic assembly became a very warm and cozy place for? ;)

It is said that when a renowned and seminal computer scientist "Grace Hopper" was working on a project in 1950's, one of her computer machines (a massive part-electrical part-mechanical) broke down because there was an actual bug (insect) in one of the circuits.

The insects caused the valves breaks, so the entire computer didn't work as expected. So engineers had to search the bug. That explains :) There's a good and interesting article about Mrs Hopper who was an incredible and pioneer woman in the computer science history:
