"Open-source software" is computer software with its source code made available with a license in which the copyright holder provides the rights to study, change, and distribute the software to anyone and for any purpose. According to The Verge, the Pentagon is going to make a big push for open-source software in 2018. "Thanks to an amendment introduced by Sen. Mike Rounds (R-SD) and co-sponsored by Sen. Elizabeth Warren (D-MA), the [National Defense Authorization Act for Fiscal Year 2018] could institute a big change: should the bill pass in its present form, the Pentagon will be going open source." From the report: We don't typically think of the Pentagon as a software-intensive workplace, but we absolutely should. The Department of Defense is the world's largest single employer, and while some of that work is people marching around with rifles and boots, a lot of the work is reports, briefings, data management, and just managing the massive enterprise. Loading slides in PowerPoint is as much a part of daily military life as loading rounds into a magazine. Besides cost, there are two other compelling explanations for why the military might want to go open source. One is that technology outside the Pentagon simply advances faster than technology within it, and by availing itself to open-source tools, the Pentagon can adopt those advances almost as soon as the new code hits the web, without going through the extra steps of a procurement process. Open-source software is also more secure than closed-source software, by its very nature: the code is perpetually scrutinized by countless users across the planet, and any weaknesses are shared immediately.
