Caffeine is a free high-performance interoperability solution between the Java platform and the .NET framework, with special emphasis on the enterprise variants of such platforms. It makes software originally written for .NET available to the Java platform. It promotes library reuse between Java and .NET by transferring APIs across environments, and allows code written for one platform to run on the other platform with minimal performance degradation. It is powered by Mono, and runs on Alpha, Linux, Windows, Mac OS X, HPPA, SPARC, and s390 systems.
Cairo is a vector graphics library with cross-device output support. It currently supports the X Window System and in-memory image buffers as output targets. It is designed to produce identical output on all output media while taking advantage of display hardware acceleration when available (eg. through the X Render Extension). It provides a stateful user-level API with capabilities similar to the PDF 1.4 imaging model and provides operations including stroking and filling Bezier cubic splines, transforming and compositing translucent images, and antialiased text rendering.
Cake is a rapid development framework for PHP which uses commonly known design patterns like ActiveRecord, Association Data Mapping, Front Controller, and MVC. Its primary goal is to provide a structured framework that enables PHP users at all levels to rapidly develop robust Web applications without any loss to flexibility.
Canumb aims to crunch data on various forms and turn them into something meaningful. A variety of inputs are currently supported, such as different number base conversions (decimal to hexadecimal, binary to hexadecimal, octal to decimal, etc.) and various encoded formats (a base64 encoder decoder and a URI encoder decoder). It's built to allow for extension when the future demands other input formats be crunched.
Catch the Furball is an icebreaker board game intended for friends to play around a computer. It features a freshly-generated board for each game, an eclectic collection of cards, and beautiful pictures of Cambridge University. The distribution is intended both to allow Web masters to quickly set up their own copy of the game, and to allow tinkerers to use the game engine to make their own games. It includes the editor used to create game data.
