iPAQ Hanheld Linux is a distribution for the iPAQ H36xx series handheld computer (PDA). It consists of a bootloader, several cramfs binary images of file systems to be loaded into flash, and the sources of modified components. It also consists of some other software that may be of use to others working on handheld computers: a Grafitti-like program, etc. It includes a fully-functioning X server based on XFree86, and basic applications.
MemMXtest is a computer program for "IBM-compatible" PCs that checks the computer's main memory for faults and defects. (Note however, that no program can be guaranteed to detect all faults, due to their very nature.) This program is aimed specifically at testing SDRAM memory modules (`DIMMs'), and uses MMX instructions to read/write all 64 databits provided by these modules at once. MemMXtest incorporates many well-known `march' tests, as well as several pseudo-random tests. The vital parts of each test use manually optimized machine code for maximal speed. The program is "stand-alone" (i.e. doesn't require an OS to run), and compiles on Linux.
World Foundry is a 3D level game engine and asset production pathway with over 170,000 lines of code. It was originaly created as a commercial product, but is now being released under the GPL. The engine was designed from the beginning to be cross platform, and ran on Windows (DirectX, GL), and the Sony Playstation. The production pathway ran on Windows, and extended 3DStudio Max to be our level editor. The engine is currently being ported to Linux (it runs, but needs work), with plans to port the production pathway as well. Developers are wanted to help with this effort.
ImSafe (Immune Security For your Enterprise) is a host-based intrusion detection tool. After a learning phase, it is able to detect changes in processes behavior, to detect buffer overflows, etc. It is implemented through a device driver (as a kernel patch) for the Linux kernel, but can also be run on other UNIX systems by using a "sensor" built upon strace.
SIMD Viterbi Decoder provides library functions to decode certain popular error correction codes. This version supports two codes: a rate 1/2, constraint length 7 (r=1/2, k=7) code, and an r=1/2, k=9 code. Four implementations of each decoder are provided. One is in portable C and should run in any GNU C environment. The other three use the IA32 SIMD (single instruction, multiple data) instruction sets: MMX, SSE, and SSE2. The SSE version of the k=7 decoder executes at ~9 megabits/sec on a 1GHz Pentium-III.
MakeNG is a system of makefiles that, in conjuncture with a patch to GNU Make, provides a concise, extensible, logically organized and easily modified system of makefiles to build any source tree or combination of components you can envision. MakeNG sports a fully documented extensible API on top of the classic GNU Make syntax (which is great for backwards compatibility).
