Why developers call it “bug”!

Why software error or anomaly is called “bug”?

One of the first big calculator, the Mark II, suddenly stopped to work during one night. Engineers, as they tried the problem, they found a moth (bug) trapped in a relay.

This was the “first case of bug being found”.

Starting from that event, the act of looking for a bug was called “debugging”, that means “pest control”.

Nice story 🙂
