Bonus

Origin of the name of Google I/O:

“A googol is a one, followed by 100 zeroes, so that's where the I/O name and logo came from. We just took the first one and zero, and we left off all the other zeroes. It all goes back to Google,” says Lorin. “And then as we were brainstorming, we started talking about what that one and zero could mean. That’s where the ‘input / output’ and ‘innovation in the open’ slogans came from.” - from Google’s website.
