On the last day of the NDC 2014 Conference in Oslo, Carl and Richard assembled a panel of speakers: Robert Virding, Steve Sanderson, Venkat Subramaniam, and Anthony Eden. The discussion focused initially on the motivations around building software, but ultimately evolved into the best way to build sustainable software. Is the profit motive for software development a good one? What about open source? How do you know when your software is 'done?' How do you decide what features to add and what to leave out or even remove? Great thinking from a remarkable set of minds!
