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.
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.
