What came first, the chicken or the egg? The computer or the computer program?
If you happen to do anything other than sleep in a cave today, chances are you have Ada Lovelace to thank for it. She is responsible for the first ever computer program. And she came up with it long before the computer even existed.
The 15th October is the fifth annual Ada Lovelace Day, celebrating the achievement of a Victorian mother-of-three who would change the world.
