If you were wondering who that stranger was that accosted you and handed out an extremely handy and undoubtedly cool ruler, you can learn more about him (and his company) by watching this interview that took place in between random ruler handouts.

Don’t forget to pick up a few copies of the newly released “Continuous Integration: Improving Software Quality and Reducing Risk” book too!
