Sajber Jukebox is a mpeg layer 3 player with a graphical user interface. It's based on Woo-jae Jung's splay for the audio and QT's graphical library for the interface. The Jukebox maintains pointers to songs on the local system or the net, and when the user wishes to play it, it opens the location and migrates the filedescriptor to the playing process. The advantage of this scheme is that the Jukebox doesn't need to worry about playing the darn thing, and the player won't have to worry about where the song is, since it'll just see the filehandle given to it, and couldn't care less of where it originally came from.
tgif is a vector-based drawing tool, with the additional benefit of being sort of a web-browser. That is, you can fetch drawings from a web server with it, and you can make objects in your picture into hotlinks to other parts of the drawing, or to other drawings accessible via HTTP.
For users on Linux and Unix, KDE offers a full suite of user workspace applications which allow interaction with these operating systems in a modern, graphical user interface. This includes Plasma Desktop, KDE's innovative and powerful desktop interface. Other workspace applications are included to aid with system configuration, running programs, or interacting with hardware devices. While the fully integrated KDE Workspaces are only available on Linux and Unix, some of these features are available on other platforms. In addition to the workspace, KDE produces a number of key applications such as the Konqueror Web browser, Dolphin file manager, and Kontact, the comprehensive personal information management suite. The list of applications includes many others, including those for education, multimedia, office productivity, networking, games, and much more. Most applications are available on all platforms supported by the KDE Development. KDE also brings to the forefront many innovations for application developers. An entire infrastructure has been designed and implemented to help programmers create robust and comprehensive applications in the most efficient manner, eliminating the complexity and tediousness of creating highly functional applications.
