Freedup finds and eliminates duplicate files by linking them, and thus reduces the amount of used disk space within one or more file systems. By default, hardlinks are used on a single device, symbolic links when the devices differ. A set of options allows you to modify the methods of file comparison, the hash functions, the linking behavior, and the reporting style. You may use batch or interactive mode. Freedup usually only considers identical files, but when comparing audio or graphics files, you may elect to ignore the tags.
Ezstream is a command line source client for the Icecast media streaming server. It can stream Ogg Vorbis and MP3 audio, as well as Ogg Theora video, either "as-is" without reencoding (which uses only very little CPU time) or it can use external decoders and encoders to convert virtually any media format into one of the supported streaming formats. Ezstream supports metadata, streaming from standard input, playlists, and external playlist scripts or programs, and more.
FrAid (Fr[actal] Aid) is a programming language that is appropriate for mathematical computations, visualization, batch processing, and more. It features both a standalone application that provides a programming environment for the language and a system for integrating the language with Java. The Java interface allows mathematical equations and formulas to be used with Java code, making it easier to process numerical computations, symbolic computations, imaging, CAD, and more.
EasyPMP is a program used to create and maintain the music database on a variety of portable music players. This allows tracks to be browsed by artist, album, genre, etc., rather than by directory structure. The following devices are supported: iRiver H100 series; iRiver H300 series; iRiver H10 UMS; iRiver H10 MTP (with emergency connect mode); iRiver H10Jr. UMS; iRiver U10 UMS; MEDION MDJuke220 and MDJuke 440; and Samsung YH-820, YH-920, and YH-925. It is developed as part of a project called PMPlib, which aims to develop a library that can be used by desktop media players and other programs, in order to support these devices.
