Airing on Thursday, June 25, 2015: First up, we’ll talk to Andrew Fitzgerald of Wall Street Journal about how much water data center uses to cool its machines. And as part of our prison technology series, we talk to the co-founder Collaborative Benefit, a LinkedIn type platform that connects incarcerated individuals with employers, about learning to code in prison.
