Ever wondered what software gets developed at a national laboratory? Thanks to the open source efforts of LLNL, you don't have to wonder any longer! Join Ian Lee, Computer Engineer at Lawrence Livermore National Laboratory, as he highlights the ongoing expansion of the open source community inside one Department of Energy research lab. These developers bring software and tools which support science and security, issues of national importance, into the open source community.
