SIMD-accelerated libjpeg-compatible JPEG codec library
libjpeg-turbo is a JPEG image codec that uses SIMD instructions (MMX, SSE2, NEON, AltiVec) to accelerate baseline JPEG compression and decompression on x86, x86-64, ARM, and PowerPC systems. On such systems, libjpeg-turbo is generally 2-6x as fast as libjpeg, all else being equal. On other types of systems, libjpeg-turbo can still outperform libjpeg by a significant amount, by virtue of its highly-optimized Huffman coding routines. In many cases, the performance of libjpeg-turbo rivals that of proprietary high-speed JPEG codecs. libjpeg-turbo implements both the traditional libjpeg API as well as the less powerful but more straightforward TurboJPEG API. libjpeg-turbo also features colorspace extensions that allow it to compress from/decompress to 32-bit and big-endian pixel buffers (RGBX, XBGR, etc.), as well as a full-featured Java interface.
Run Linux on Windows or other OSes, natively.
Cooperative Linux is the first method for optimally running Linux on Windows and other operating systems natively. It is a port of the Linux kernel and support code that allows it to run cooperatively without emulation along with another operating system.

Automated integer factorization
YAFU (with assistance from other free software) uses the most powerful modern algorithms (and implementations of them) to factor input integers in a completely automated way. The automation within YAFU is state-of-the-art, combining factorization algorithms in an intelligent and adaptive methodology that minimizes the time to find the factors of arbitrary input integers. Most algorithm implementations are multi-threaded, allowing YAFU to fully utilize multi- or many-core processors (including SNFS, GNFS, SIQS, and ECM). YAFU is primarily a command-line driven tool. You provide the number to factor and, via screen output and log files, YAFU will provide you the factors. There is also an interactive environment similar to MATLAB or PARI/GP, where you can type commands and store results. YAFU is very customizable, through the optional use of many many command line parameters and a very capable expression interpreter.

ezQuake has moved to Github: https://github.ezquake.io
NOTE: ezQuake has moved to github! https://ezquake.github.io Sourceforge is no longer used! ALL FILES FOUND HERE ARE _OLD_, PLEASE MOVE TO https://ezquake.github.io FOR THE LATEST VERSIONS Combining the features of all modern QuakeWorld® clients, ezQuake makes QuakeWorld® easier to start and play. The immortal first person shooter Quake® in the brand new skin with superb graphics and extremely fast gameplay. The project started in August 2004 as a derivate of the FuhQuake client by fuh which is a derivate of ZQuake QuakeWorld client by Tonik, one of the current ezQuake developers. Finally, ZQuake is a derivate of QuakeWorld client made by Id Software. This company has created the Quake game itself and later on released the source codes of game executables under GNU General Public License. Because id Software didn't release the whole game for free to the public you still need some of the original files from Quake to play QuakeWorld using our client.
