Ruby-GConf allows Ruby developers to write applications that store their configuration data using GConf (1.0.x). GConf is a configuration database system written by Havoc Pennington et al, and part of the GNOME application development framework (although it can be used separately).
OpenAL, the Open Audio Library, is a joint effort to create an open, vendor-neutral, cross-platform API for interactive, primarily spatialized audio. Its primary audience is made up of application developers and desktop users that rely on portable standards like OpenGL for games and other multimedia applications.
OGRE (Object-Oriented Graphics Rendering Engine) is a class library written in C++ designed to make it easier and more intuitive for developers to produce games and demos utilising 3D hardware. It exposes a number of useful objects allowing you to create and manipulate a 3D environment and render it to your specifications, while removing the unnecessary complexities of the underlying system libraries like Direct3D and OpenGL.
XCard is a Leitner based French flashcard program, used to help students memorize French words. It comes with several default word lists, ranging from verb lists, to vocabulary associated with airplane travel. It has the capability to repeat lesser known words, graph a student's progress, translate words to French, and to create new word lists. It is deployed via Java Webstart, and can be run from the XCard homepage.
LPSM is a C library with a simple interface that manages a segment of memory backed by a persistent file. It differs from ordinary mmap() in two ways: it can optionally offer heap management (malloc/free/realloc) within the arena, and more importantly, a transaction log is used to ensure the consistency of the persistent representation. The application notifies LPSM whenever the arena is in a consistent state, suitable for checkpointing. If the application or system crashes, the arena will always be recovered to a consistent checkpoint.
OpenSG is an Open Source scenegraph system. Its design goals include high performance, multithread-safe data handling, high flexibility, extensibility, and portability to Irix, Linux, and Windows. A number of computer graphics research institutions are actively working on moving the system beyond the state of the art to include features like clustering, subdivision surfaces, occlusion culling, and more.
JWAA is a software framework for building dynamic Web applications as networks of first-class Java objects. XML is used for representing information normally coded as HTML. The XML files are automatically reloaded when they change. It has a "persistent forms" feature in which form data automatically persists in the database such that fields behave like pieces of paper that automatically preserve what's written on them. This default behavior is easily overridden. Invalid links are reported at XML load time via the browser, and are also recorded in log files.
The JOpenChart library and toolkit provides the means to create different kinds of charts, including pie charts, line charts, and plot charts. Furthermore, it contains components for embedding charts into Swing or Web applications. The library's Renderer Interface API makes it very easy to add new renderers for different chart types. Classes to interpolate measured data and to plot mathematical functions are also included.
