Wendland TD is a German Tower Defense like game. In this game, the player's goal is to stop a truck or train (you can choose between a street or rails in the main menu) by placing obstacles like garbage, cows, or other trucks on the road/rails. This game is only available in German, because it is related to events that are actually happening like this in Germany.
fretscpp is strongly inspired by the original FoF, reusing artwork to a large extent, with the source code rewritten from scratch. C++ instead of python should improve performance and allow easier support for features like whammy. It is playable, but some non-critical features are still missing.
lemontree provides a very fast Java class for the Walsh Hadamard transform (WHT) and O'Connor transform (OCT). You can regard the OCT as a black box which turns arbitrary numerical data into data with a Gaussian distribution. There are inverse transforms, also. It has many applications, such as Random Projections, Compressive Sensing, Neural Nets, and Genetic algorithms.
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.
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).
