“The first computer ‘bug’ ever found.” was penned precisely on 13 December, 2007 12:46 PM, which happened to be a Thursday. but you know what? dullneon.com's random notes has now moved to a new location.
A moth found was found trapped between the Mark II Aiken Relay Calculator while being tested at Harvard University in 1947. The moth was literally added to the computer log and tagged as the “First actual case of bug being found”. Later, they would use the word “debugged” when the moth was removed from the machine.
this was published on 13 December in the year 2007, which was a Thursday. anyway, all this is old and archived. everything has been now been moved, so head on down to the revamped almost daily random notes (unless of course you like this old stuff too much to part with it).
