The SDL Sand game (The Falling SDL-Sand Game) is a C++ implementation of the original 'World of Sand' (and later 'Hell of Sand') game implemented in JAVA. SDL Sand uses the SDL (Simple DirectMedia Library - http://www.libsdl.org/) library for screen output. Therefore the implementation can possibly run on every platform supported by SDL.

A clone of an old C64 game. The object is to destroy your opponent's house with the power of weather, before they do the same to you. Play against the computer AI, or against another player locally or over the network.

VIGRA stands for "Vision with Generic Algorithms". It's a novel computer vision library that puts its main emphasize on customizable algorithms and data structures. By using template techniques similar to those in the C++ Standard Template Library, you can easily adapt any VIGRA component to the needs of your application, without thereby giving up execution speed.

This package contains all necessary ANSI-C source files to build a running Forth-environment on most UNIX machines, on DOS and on OS/2. The Forth-system is closely modeled along the new American National Standard for the programming language Forth. Every word of every word set mentioned in the dpANS-6 document of June 1993 has been implemented. Additionally it is compatible to Forth-83.

Sender Policy Framework (SPF) library and client in C. SPF is a standard under development for email envelope sender verification. Domain owners can specify who is qualified to send mail for the domain by publishing SPF TXT records in DNS. Read all about SPF at http://spf.pobox.com/

CCMATH is a mathematics library, coded in C, that contains functions for linear algebra, numerical integration, geometry and trigonometry, curve fitting, roots and optimization, Fourier analysis, simulation generation, statistics, special functions, sorts and searches, time series models, complex arithmetic, and high precision computations.

This is a collection of stopgap replacements for standard math functions missing from libm in various supported versions of FreeBSD. The functions are slower than the existing libm functions, but are more accurate than many naive replacements. Exceptions are largely ignored. N. Beebe's extended C version of the ELEFUNT package is used to provide regression tests for some of the real-valued functions.

Mathomatic is a highly portable, general purpose CAS (Computer Algebra System). Mathomatic can: * Solve, simplify, and compare algebraic equations, * Perform calculus transformations, * Help with finite series analysis, * Perform complex number and polynomial arithmetic, * Generate efficient C or Java code from equations.

This module extends Python with a Graph class which is capable of handling arbitrary directed and undirected graphs with thousands of nodes and millions of edges. Since the module makes use of the open source igraph library written in almost 100% pure C, it is blazing fast and outperforms most other pure Python-based packages around.

flvtool++ is a tool for hinting and manipulating the metadata of FLV files. It was originally created for Facebook's Video project (http://facebook.com/video/) for fast video hinting. It is loosely based on the Ruby FLVTool2, but is written in C++ for performance reasons.
