Chris DiBona is the Open Source Programs Manager at Google. He discusses Google's extensive use of open source software as infrastructure and for building platforms like Android, Google Web Toolkit, and Google Chrome. DiBona explains that Google contributes to open source to maintain independence, gain flexibility, and appeal to their ethos. Google takes part by releasing over 3 million lines of code, hosting projects on Google Code, patching hundreds of projects, and participating in programs like Summer of Code which funds student open source work.
