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.

Jennylab is a open project learning, examples and security material.

A library written in Objective-C for linux or others gcc-enabled systems that brings support of slots and signals ŕ-la Qt in the language, and a windowing toolkit made in OpenGL or X11. Other useful tools may also be included such as XML.

OpenPoplog is a multi-language, incrementally-compiled virtual machine-based development environment with its own extensive teaching and support material, supporting the languages Pop-11, Prolog, Common Lisp and ML on Unix, VMS, Linux and Windows.

Hoard is a multiprocessor memory allocator that is fast, memory-efficient, and scalable. If you are running multithreaded code on a multiprocessor system, Hoard can dramatically improve your application's performance without any changes to your source.

VILE is a high performance logging tool for C and C++ programs. VILE can be used for debugging or performance analysis.
