Cadabra is a computer algebra system designed specifically for the solution of problems encountered in field theory. It has extensive functionality for tensor polynomial simplification including multi-term symmetries, fermions and anti-commuting variables, Clifford algebras and Fierz transformations, implicit coordinate dependence, multiple index types, and many more. The input format is a subset of TeX. Both a command-line and a graphical interface are available.
Cadena is an Eclipse plugin that provides an integrated environment for building and modeling component-based systems (including CORBA CCM systems). It provides editors for defining component types, specifying component behavior, and creating and visualizing component assemblies. It also provides facilities for generating stub and skeleton source code for components, performing dependency analysis that traces inter/inta-component event and data dependencies, executing the developed systems, and more.
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.
The Cafu Engine is an all-purpose, modern 3D graphics engine and game development kit. It is feature complete to get you started quickly. It can be used to create a variety of 3D applications, including games, simulations, and training and architectural software. Written in C++, the tools, libraries, and framework have been designed to make the development of new games and other 3D applications easy. They are actively and continuously developed in order to provide the latest technology.
CairoForPHP is an application that demonstrates several functions of the Cairo implementation for PHP. It uses a technique with which, from the same source, it can run both as a desktop application with PHP-GTK and as a Web application, thus demonstrating how PHP-GTK can be used as "just one" method of output and integrated into multi-platform, multi-environment applications. The samples in CairoForPHP are fully adjustable, and code can be "dropped-in" easily in the non-Phar versions: all required additional data interfaces are XML-based. The integrated samples come both pre-rendered and in live rendering, demonstrating both abilities of Cairo here and PHP-GTK's utilization with Cairo in the realization of it. CairoForPHP uses several technologies in order to achieve all this, such as XML-based data interfaces (including XML Schema validation), PHP-GTK, Phar compatibility, Gettext integration, and others.
Calcoo is a scientific calculator designed to provide maximum usability. Its features bitmapped button labels and display digits to improve readability, no double-function buttons, undo/redo buttons, copy/paste interaction with the clipboard, both RPN and algebraic modes, two memory registers with displays, displays for Y, Z, and T registers, and tick marks to separate thousands. Calcoo is written in C using the GTK+ widget library (v.2.2+).
Calcurse is a text-based calendar and scheduling application. It helps keep track of events, appointments, and everyday tasks. A configurable notification system reminds the user of upcoming deadlines, and the curses based interface can be customized to suit user needs. All of the commands are documented within an online help system.
