Lernstick is a Live Linux distribution with focus on education; it is usually installed on USB sticks. To provide up-to-date software choice on a solid base, it uses a combination of Debian stable with official and custom backports. Although the distribution is mainly used on removable media (USB sticks, USB hard disks, SD cards, etc.), it can also be installed on internal hard drives.
FusionForge is a collaborative development environment that gathers in one single place several tools useful for development teams: communication tools (forums, mailing-lists, news, etc.); development tools (bug/patch trackers, project management, source control systems, etc.); and community tools (file releases, software categorization, Web site hosting, etc.). It is the continuation of the free software version of GForge, based on the codebase that was maintained in parallel to the proprietary GForge AS version.
