The Debea Database Access Library is a collection of interfaces that map C++ objects to relations in various SQL and file databases. The library uses a plug-in architecture to support various SQL RDBMSes and provides one simple interface for query processing and object serialization. There is a wrapper for wxWidgets that replaces the original dba API with a wx-friendly version.
libjpeg-turbo is a high-speed version of libjpeg for x86 and x86-64 processors. It uses SIMD instructions (MMX, SSE, SSE2) to accelerate baseline JPEG compression and decompression. libjpeg-turbo is generally 2-4 times as fast as the unmodified version of libjpeg. It also includes a wrapper library for the TurboJPEG API used by VirtualGL and TurboVNC. It was originally based on libjpeg/SIMD but has improved support for Mac OS X, 64-bit platforms, 32-bit and big endian pixel formats (RGBA/BGRA/ABGR/ARGB), accelerated Huffman encoding/decoding, and various other fixes.
