juked is a daemon that turns a server into a music jukebox. Clients communicate with the server via TCP/IP using an XML protocol. It features playlist support, user authentication (optionally with PAM), and random track selection. Audio decoding is done using XMMS plugins, so both Ogg and MP3 are supported. Track (song) information can be stored internally or in a MySQL database.
Jython is a Java implementation of the Python programming language. It allows users to compile Python source code to Java byte codes, and run the resulting bytecodes on any Java Virtual Machine. It is a very seamless and smooth integration with Java: from Python you have complete access to all Java libraries, can build applets, can integrate with Java beans, and can subclass Java classes in Python and vice versa. Like Python, and unlike Java, Jython can also be used interactively: just type some Jython code at the prompt and see the results immediately.
K-3D is a 3D modeling, animation, and rendering system for GNU/Linux & Win32. Features include creation and editing of geometry in multiple realtime OpenGL solid, shaded, and texture-mapped views; unlimited undos and redos; complete extensibility at runtime through third-party plugins; animated procedural geometric effects; all parameters animatable through a consistent control-spline based interface; rendering pipeline to Renderman Interface compliant rendering engines; optimization for use with the Aqsis rendering engine, which features solid modelling, true displacement, and user programmable shaders; and support for background and batch rendering.
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.
Libxml2 is the XML C library developed for the Gnome project. The library code is portable (to Linux, Unix, Windows, embedded systems, etc.) and modular; most of the extensions can be compiled out. Libxml2 implements a number of existing standards related to markup languages, including the XML standard, Namespaces in XML, XML Base, Relax NG, RFC 2396, XPath, XPointer, HTML4, XInclude, SGML Catalogs, and XML Catalogs. In most cases, libxml tries to implement the specifications in a relatively strict way. To some extent, it provides support for the following specifications, but doesn't claim to implement them: DOM, FTP client, HTTP client, and SAX2. Support for W3C XML Schemas is in progress. It includes xmllint, a command line XML validator.
With LinkChecker, you can check HTML documents and Web sites for broken links. It features recursion, robots.txt exclusion protocol support, HTTP proxy support, i18n support, multithreading, regular expression filtering rules for links, and user/password checking for authorized pages. Output can be colored or normal text, HTML, SQL, CSV, or a sitemap graph in DOT, GML, or XML format. Supported link types are HTTP/1.1 and 1.0, HTTPS, FTP, mailto:, news:, nntp:, Telnet, and local files.
