sqlzma is a patch against lzma and squashfs that makes squashfs support both LZMA compression and ZLIB compression. A squashfs image file that uses LZMA compression has no backward compatibility, but the patched squashfs and its tools can handle the old squashfs image generated by the unpatched squashfs-tools.
ctunnel is a program for tunneling and proxying TCP or UDP connections via a cryptographic tunnel. ctunnel can be used to secure any existing TCP or UDP based protocol, such as HTTP, Telnet, FTP, RSH, MySQL, VNC, DNS, XDMCP, NFS, etc. You can also chain or bounce connections to any number of intermediary hosts.
DIPC allows an application programmer to easily (transparently) send and receive data, synchronise using semaphores, and use a shared memory over a network. Distributed computing is thus made very easy. DIPC modifies System V's message queues, semaphores, and shared memory segments so that they can operate not just within a single computer, but over a cluster of computers. The programming model is very similar to that of a group of processes running on the same computer and exchanging data.
Whitix is a modern operating system eventually aimed at the desktop market. It currently runs on x86 processors and features a fully functional desktop and graphical user interface, text editor, shell, Python, Lua C compiler, assembler, and make equivalent. Whitix is available in a live CD format for download.
sk98lin is a Marvell Yukon/SysKonnect Linux driver. In the release candidates for Linux 2.6.23, the sk98lin driver was removed under the presumption that the sky2 and skge drivers would be sufficient to cover all hardware supported by the unmaintained sk98lin driver. That presumption was wrong, as several NICs will not work at all with skge and stop talking after an indeterminate period of traffic with sky2.
CinayOS is a 64-bit operating system that was forked from Linux in order to develop a radically different approach to concurrency, SMP, and most other kernel subsystems. Its goals include a new caching infrastructure, easy software package management, and an OpenGL accelerated animation system.
