Using gravity, dominoes, bowling balls (and other balls), ramps, balloons and cola bottles primed with Mentos, The Butterfly Effect invites you to solve physics puzzles and knock over the bowling pin at the end. In case you get stuck, the friendly Post-it Boy has left his clues where they might come in handy. This game is not entirely unlike the famous game "The Incredible Machine".
FNV hashes are designed to be fast while maintaining a low collision rate. The high dispersion of the FNV hashes makes them well-suited for hashing nearly identical strings such as URLs, hostnames, text, and IP addresses. FNV is used in a wide variety of applications including mdbm, DNS, web search engines, NFS, Netnews, etc.
XML User Profiles is a system that allows for remote and transferable user accounts. The file format is a lightweight but flexible vCard transformation that allows better profile sharing and simpler implementations than FOAF. The current specification and a few sample implementations in PHP are provided. The library currently allows for authentication against the simple LOGIN interface or the Drupal XML-RPC service in addition to the distributed and strong authentication LID-1.0 and OpenID-0.0 single-sign-on systems.
Zend Framework Installer is a PHP class that can be used to setup files for an application based on the Zend framework. It creates a common directory structure as recommended in the Zend Framework's manual. The class can also generate a bootstrap file and the index controller with its view.
socket_wrappers is an improved version of tcp_wrappers. The improvements include changing from K&R to ANSI C, removing unneeded compatibility libraries, separation of the public and private API, prepending tcpd_ to all private functions and data to prevent name collisions, updates to signal handlers so that the application's handlers aren't tampered with, dropping supplemental groups, and some build and man page improvements. Applications compiled with this library should be smaller, too.
s11n ("serialization") is a C++ library for easily serializing a wide variety of objects, including PODs, STL containers, and user-defined Serializable types. It is completely data-format agnostic and currently supports several data formats, including three XML dialects. It is amongst the most advanced, most flexible, simplest to use, and most powerful serialization frameworks ever created for C++.
Khayyam is a program for composing 3D scenes for rendering (similar to Poser and DAZ Studio). It can import character and scene models from many model formats (Poser, MD5, BSP, OBJ, 3DS, Collada, and formats used in most Illusion games). There is support for basic object placement, scaling, posing skeletal characters, and lighting. Scenes can be exported in POV-Ray format for rendering. Khayyam is implemented as a shell program using many libraries from the Floyd and Sodipodi projects.
