.wwf toolkit is a set of shell scripts to convert PDF files to .wwf files and vice versa. The resulting .wwf files are virtually indistinguishable from files created with the official WWF drivers. The PDF files the toolkit creates are fully unprotected and can be printed or manipulated by other PDF utilities.
Giada is a minimal, hardcore audio tool for DJs and live performers. Just pick your sample, drop it in any channel, and start the show by using this tiny piece of software as a loop machine, drum machine, sequencer, live sampler, or effect (VST) host. Giada aims to be a compact and portable virtual device for production use and live sets.
TCRun is a tool written by software engineers in QA to help in writing, managing, and running automated test cases. The current version is written in C# for use on Windows, though other versions / platforms may be created later as necessary. It tries to make writing automated test cases as simple and painless as possible. It includes support for NUnit exceptions, logging (both test case specific and framwork/runtime), parameterized tests, test case resource files, and a validation framework. It can be used in mono, but is somewhat untested (it's actually built by mono, and it tests itself).
StatusNet Desktop is a dedicated multi-platform client for connecting to StatusNet messaging servers (requires a server running 0.9.3 or later). The client can connect to multiple StatusNet sites to read and post updates, including secure and private installations. Home, public, individual, and group timelines can be read and posted to, as well as direct user-to-user messages and keyword searching of the public notice stream. Support for StatusNet-specific features such as user groups is explicitly included, where these are usually not supported by generic Twitter-API clients.
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.
