David "DHH" Heinemeier Hansson (@dhh) is the creator of Ruby on Rails, founder and CTO at Basecamp (formerly 37signals), and the best-selling co-author of Rework and Remote: Office Not Required. Oh, and he went from not having a driver's license at 25 to winning, at 34, the 24 Hours of Le Mans race, one of the most prestigious automobile races in the world. It is often called the "Grand Prix of endurance and efficiency." Listeners had a million questions we didn't get to last time, so he's back for round two because his episode is about to cross a million downloads -- and that's in barely two weeks! In this episode, DHH discusses: Digital security The value of schooling Three questions you should be able to answer Company culture How bladder relief happens in a 24-hour race And much, much more! Please enjoy my round 2 conversation with DHH! Show notes and links for this episode can be found at www.fourhourworkweek.com/podcast.
