Happy Tester's Day

“First actual case of bug being found”
On Wednesday 09 September 2015 by Julianne Whooley

On September 9, 1945 the scientists of the Harvard University while testing the computer Mark II Aiken Relay Calculator, found a moth which got stuck between the contacts of the electromechanical relay.

 

The work they performed required some description, and the word has been found – «debugging» (literally: disposal of an insect) – and nowadays it is used to describe the process of identifying and eliminating bugs which cause a computer to malfunction.

The removed insect was pasted into the computer log with the entry: “First actual case of bug being found”, and was then transferred to the computer museum.

Happy testers day!
