No one ever said open sourcing code at the DoD would be easy.  Nevertheless, in February 2017 the Defense Digital Service set out to bring some much needed guidance to the Department. These efforts produced the Code.mil project: an experiment in open source at the Department of Defense. This session will cover some of the challenges faced by the amazing service men and women (and civilians) as they promote a more open technology landscape. We'll highlight some of the great work that goes on in the DoD and the ongoing efforts to enable OSS at the DoD and across the Federal Government, including some great success stories.
