First mentioned computer bug

I just saw the first computer bug that was mentioned long before the term became quite popular in the last 50 years. (Rear Admiral) Grace Hopper, a famous computer pioneer, wrote in her notebook that a moth was found in a relay of her Mark II Aiken Relay Calculator, which lead to a failure. This was at a time where a computer bug had a actual real representation which could be posted into a notebook, as shown below 😉

How to explain nanoseconds?

One of the most amazing and informative talks i have ever saw on YouTube, where Grace Hopper (Rear Admiral of the US Navy) explains the value of a nanosecond. Grace Hopper, who is often refrerred to as ‘Amazing Grace‘ is one of the first real computer pioneers. She conceptualized the idea of machine-independent programming languages, which led to the development of COBOL, one of the first modern programming languages. Can you imagine that one of the Navy’s destroyer USS Hopper is named after her 🙂
