In 1947, Grace Murray Hopper was working on the Harvard University Mark II Aiken Relay Calculator (a primitive computer). On the 9th of September, 1947, when the machine was experiencing problems, an investigation showed that there was a moth trapped between the points of Relay #70, in Panel F. The word went out that they had "debugged" the machine and the term "debugging a computer program" was born In today’s web 2.0 world, we have more complicated software, and more bugs. We have dedicated teams of testers just to find them.
