computer history
Today in 1947 Grace Hopper found the first computer bug.
In many reports the date is 9th of September 1947. There are some theories about this discrepancy. One theory is they actually found the bug on 7th of September but realized it's importance two days later and wrote it down in the log. Another theory is the bug was presented in a meeting two days later as the cause of the problem and became known to a wider group of people.
It's also possible the date in her notebook was a simple mistake and the 9th is the real and official date.
Anyways, she found it!
