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.

Delay-Tolerant Networking suitable for use in spacecraft
The Interplanetary Overlay Network (ION) software distribution is an implementation of Delay-Tolerant Networking (DTN) architecture, as described in Internet RFC 4838, that isintended to be usable in embedded environments including spacecraft flight computers. If you're interested in the use of Delay-Tolerant Networking in space flight operations, check out the Interplanetary Networking Chapter of the Internet Society: ipnsig.org. NOTE a bad typo (fix coming in 3.6.2): if you want to use SBSP, you *must* change "SPSB" to "SBSP" in line 307 of bp/library/ext/bpextensions.c before rebuilding with -DSBSP. OTHER NOTES: 1. A new ION Android developer's kit is now available. Download the Linux ION distribution, then look at the README in arch-android. 2. Two new Windows installers are also now available. The new default Windows download is for 64-bit Windows. For 32-bit Windows, please download ION-Installer32-3-6-1.zip.
The OVAL Interpreter is a freely available reference implementation that demonstrates the evaluation of OVAL Definitions. Based on a set of OVAL Definitions the interpreter collects system information, evaluates it, and generates a detailed OVAL Results file. Developed to demonstrate the usability of OVAL Definitions and to ensure correct syntax and adherence to the OVAL Schemas by definition writers, it is not a fully functional scanning tool nor an enterprise scanning tool. It is a simplistic, command-line application that has the ability to execute OVAL Content on an end system. To learn more about organizations that provide OVAL content and tools or otherwise support the OVAL Language, please see the OVAL Adoption Program (http://oval.mitre.org/adoption/).
