Joe Belfiore’s T-Shirt at Build Explained!

By Rich W Woods

During the Build 2015 Day One keynote, you might have noticed that Joe Belfiore was wearing an interesting keynote. He even made reference to it during the keynote, suggesting that there was something to decode in there.

The t-shirt was in binary, meaning that it was a combination of ones and zeroes that makes up the Windows logo. Kévin Gosse was the developer to decode the message. Have a look:

  1. There are 10 types of people in the world
  2. Windows 10, Because 7, 8, 9
  3. Congrats on being one of the first
  4. Windows Insiders help us develop the future. Talk to us @ Windows

Note that “There are 10 types of people in the world” is a very old programmer joke that goes “There are 10 types of people in the world: Those that understand binary and those that don’t.”

My personal favorite is the next version of that joke, being “There are 10 types of people in the world: Those that understand binary, those that don’t, and those that didn’t know this joke would be in base 3!”
