Open Source Software: The Mega List - Datamation

Throughout the year, Datamation publishes guides to open source software in a variety of different categories, such as security, cloud computing, big data, small businesses, mobility and even games. It's become an annual tradition to compile all those open source apps we've featured into one gigantic list.

Our 2012 guide is longer than ever before with a jaw-dropping 1000+ open source apps in all. As usual, we've divided the list into categories and then alphabetized the projects within each category.
