>>A few years ago I visited a museum in London where they house one of the very first electrical computers ever built. It was this huge contraption with a number of relays that clunked shut or sprang open in order to generate on-off bit arrays. Not only did the programmers of that computer have to debug their code, but they had to actually literally debug the computer itself by scraping off cockroaches that occasionally got squished between the relays and thereby insulating the contact. Hence the term "debugging". Talk about the good old days of computing! In the same vein, I am sure that a hundred years from now programmers will look at what we do/did today and shake their collective head at the primitiveness of it all...

Who really knows... Or cares. The museum I visited claimed to have a few squished cockroaches in the storage, but I did not see them, nor did I want to see them personally. What is generally agreed is that the early relay -based technology was prone to erroring out due to errant bugs, and hence the term.
