crtmpserver it is a high performance streaming server able to stream (live or recorded) in the following technologies: to and from Flash (RTMP, RTMPE, RTMPS, RTMPT, RTMPTE), to and from embedded devices (such as iPhone and Android), from surveillance cameras, and with IP-TV using MPEG-TS and RTSP/RTCP/RTP protocols. Also, crtmpserver can be used as a high performance rendesvous server. For example, it enables you to do audio/video conferencing, online gaming, online collaboration, and simple or complex chat applications.
PropXX provides a property/configuration mechanism for C++ applications. Properties can be defined in files similar to but more flexible than Java properties. Property files are defined in a type-safe, modular way and offer the full expressiveness of the Lua scripting language. The design of PropXX combines flexibility with high performance for the C++ code that accesses property values. The property values are stored in objects of special property classes, which are automatically generated from the property set definitions. Performance-critical code can be inlined by the compiler, and a typical access to a property value is as cheap as reading a single variable from the memory. No costly data structures like hashes, balanced trees, etc. are involved.
GSL shell offers an interactive user interface that gives access to the GSL collection of mathematical functions. It is based on the powerful and elegant scripting language Lua. GSL shell is not just a wrapper over the C API of GSL, but offers a much more simple and expressive way to use GSL. The objective is to give the user the power to easily access GSL functions without having to write a complete C application. It also has a powerful module to produce plots or almost any kind of graphics based on data or functions.
AKFAvatar is a fancy graphical user interface for text oriented applications where an avatar appears on the screen and provides information in a balloon. It also supports recorded audio files. Applications for AKFAvatar can be written in Lua, and there are interfaces for C, Objective C, C++, Free Pascal, and GNU Pascal. A number of ready-to-use applications and modules are provided, including a text viewer and a module that makes question-answer exercises. For POSIX-compatible operating systems there is a man page viewer and a terminal emulator, which makes it possible to run many existing terminal-based programs in this fancy environment.
Devilspie2 is a utility to find windows and changes properties of these windows with the help of rules written in LUA. For example, you can make a window of an application always appear at the same screen position each time it starts. It is a continuation of the program Devilspie, written by Ross Burton.
Five Hundred is a card game for four players similar to Euchre or Bridge, especially popular in Australia and New Zealand. The wikipedia page has a comprehensive description of gameplay.
