Jeremy Brown discusses Red Hat's open source business model and principles for selecting software. Some key points: 1. Red Hat's model is "community powered innovation" - it contributes to and leads many open source communities while also offering long term enterprise support subscriptions. 2. Jeremy's rules for selecting software emphasize proven solutions, long term support, predictable costs, minimizing lock-in, and not paying for upgrades. 3. For open source specifically, the size and growth of the community as well as licensing terms that allow forking are important factors.
