“From then on, when anything went wrong with a computer, we said it had bugs in it.”

— Grace Hopper

On the removal of a 2-inch-long moth from the Harvard Mark II experimental computer at Harvard in 1947, as quoted in Time (16 April 1984). Note that the term "bug" was in use by people in several technical disciplines long before that; Thomas Edison used the term, and it was common AT&T parlance in the 1920s to refer to bugs in the wires. Hopper is credited with popularizing the term's use in the computing field.

“When we had no computers, we had no programming problem either. When we had a few computers, we had a mild programming problem. Confronted with machines a million times as powerful, we are faced with a gigantic programming problem.”

“Imagine creating a huge software program that can only be tested in little pieces on a computer that is slightly different from what it is supposed to run on. However, when you do run it as a whole on the actual computer for the first time, it must run almost flawlessly without a single significant bug. When is the last time you saw a software program do that?”

“When you write a computer program you've got to not just list things out and sort of take an algorithm and translate it into a set of instructions. But when there's a bug — and all programs have bugs — you've got to debug it. You've got to go in, change it, and then re-execute … and you iterate. And that iteration is really a very, very good approximation of learning.”

“When you use Google, do you get more than one answer? Of course you do. Well, that’s a bug. We have more bugs per second in the world. We should be able to give you the right answer just once. We should know what you meant. You should look for information. We should get it exactly right and we should give it to you in your language and we should never be wrong. That’s our challenge.”
