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.
Statsnet is a small set of scripts that will generate graphical statistics for a specific device. The statistics contain among other things, transmitted/received packets as well as bytes. In addition, it shows amount of currently tracked connections in the conntrack engine of netfilter.
The system call tracker is a Linux kernel module and supporting user space applications which allow interception of and possibly taking action upon system calls that match user-defined criteria. It allows you to set such rules as "tell me when someone tries to open /etc/passwd" and "if user '500' tries to connect to the network, fail the system call". It can also be thought of as strace on steroids.
Tiara is a BIOS replacement that boots an unmodified Linux kernel directly from the disk or the ethernet on any SiS 530/5595 Motherboard. It supports auto-sizing of memory and cache, PCI, IDE, VGA, SUPERIO, ENET, SOUND setup, and init. It supports the console on the std VGA(530) or via the SERIAL port(6801) from powerup, includes a Forth interpreter in flash and some diags, and fits nicely in 128kb of flash.
translucency is a loadable kernel module for Linux that virtually merges two directories, making it possible to overwrite files on read-only media and compile projects (such as the Linux kernel) with different options without copying sources each time. No user-space tools have to be changed. The process is also known as inheriting (ifs), stacking, translucency (tfs), loopback (lofs), and overlay (ovlfs).
