DHH = David Heinemeier Hansson is one of the creators of the Ruby On Rails framework and an active collaborator of 37signals. I’ve read several articles about the company and RoR, but this was the first time I saw David in action. This lecture about “The Secret To Making Money Online” is full of great ideas and gives you a chance to think about “simplifying” your goals (following the approach “Less is More”) and getting things done.
