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.

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.
A multi-format module player and library
xmp is a module player for Unix-like systems that plays over 90 mainstream and obscure module formats from Amiga, Atari, Acorn, Apple IIgs and PC, including Protracker (MOD), Scream Tracker 3 (S3M), Fast Tracker II (XM) and Impulse Tracker (IT) files.

Linear algebra and solver library using CUDA, OpenCL, and OpenMP
ViennaCL provides high level C++ interfaces for linear algebra routines on CPUs and GPUs using CUDA, OpenCL, and OpenMP. The focus is on generic implementations of iterative solvers often used for large linear systems and simple integration into existing projects.
A Forth compiler with a little difference
4tH is a Forth compiler with a little difference. Instead of the standard Forth engine it features a conventional compiler. 4tH is a very small compiler that can create bytecode, C-embeddable bytecode, standalone executables, but also works fine as a scripting language. It supports about 95% of the ANS Forth CORE wordset and features conditional compilation, pipes, files, assertions, forward declarations, enumerations, structures, suspended execution, recursion, include files, etc. It comes with an RPN calculator, line editor, preprocessor, compiler, decompiler, C-source generator, a virtual machine, and a multitasking environment.

This project represents XLSX files` writer written in C++
This library represents XLSX files writer. The main feature of this library is that it uses C++ standard file streams. On the one hand it results in almost unnoticeable memory and CPU resources consumption while processing (that may be very useful at saving a large data arrays), but on the other hand it makes unfeasible to edit data that were written down once. Hence, if using this library the structure of the future report should be known enough. The library is written in C++ with using STL functionality and based on the simple XML writer and ZIP library. Both of them have free licenses. http://www.codeproject.com/Articles/5588/Simple-C-class-for-XML-writing http://www.codeproject.com/Articles/7530/Zip-Utils-clean-elegant-simple-C-Win32
PHP bindings for the cross-platform GUI library wxWidgets.
wxPHP is a php binding/wrapper for the cross-platform library wxWidgets, which gives you the ability to develop desktop applications using the php programming language. This applications can be executed on windows, linux and macosx using the same code base with a native look and feel. One of the ideas is that you can use your php web applications code base and logic to create native desktop applications that communicate to them transparently. This way you can give your users a seamless and native experience from the desktop while staying in sync with your web apps. There are many more use cases, but we invite you to download and try this project by your self. We hope everyone can enjoy it as much as we have enjoyed developing it.
C library for sending e-mail (with attachments) from C/C++
C library intended to give C/C++ developers a quick and easy way to send e-mail from their applications. Supports multiple To/Cc/Bcc recipients and multiple attachments without size limitation.
