Linux is a clone of the Unix kernel, written from scratch by Linus Torvalds with assistance from a loosely-knit team of hackers across the Net. It aims towards POSIX and Single UNIX Specification compliance. It has all the features you would expect in a modern fully-fledged Unix kernel, including true multitasking, virtual memory, shared libraries, demand loading, shared copy-on-write executables, proper memory management, and TCP/IP networking.
Puppy Linux is a Linux distribution that is about 100 megabytes, yet it includes a complete set of graphical applications, combined with extensive utility applications. Puppy was created from scratch, file-by-file, optimized for size at every step. Another feature of Puppy Linux is that it can work totally without a hard drive, even allowing you to save data and install extra packages by saving back to the CD or DVD.
DMAring demonstrates a novel generic network interface card driver architecture which works in hybrid interrupt-polling mode to deliver superior real-time performance on Linux, Red Hat Linux, or Linux-RTAI-LXRT (a real-time co-kernel for Linux with user level extension). Existing Linux drivers saturate the CPU at a much lower packet rate than the maximum possible wire line packet rate, but this driver allows vanilla network cards to be used for high speed packet capturing.
Papillon is a security module designed for the Solaris Operating Environment. It provides security mechanisms and protections that improve the overall security of the system by adding new functionality to the kernel such as a restricted proc, chroot environment protections, secure STDIO file descriptors, restricted symlinks in /tmp, setuid protections, and more. In the current version Papillon supports Solaris (8, 9, and 10) and OpenSolaris running on x86 and SPARC architectures in 32- or 64-bit mode.
G4L is a hard disk and partition imaging and cloning tool. The created images are optionally compressed, and they can be stored on a local hard drive or transferred to an anonymous FTP server. A drive can be cloned using the "Click'n'Clone" function. G4L supports file splitting if the local filesystem does not support writing files larger than 2GB. The included kernel supports ATA, serial-ATA, and SCSI drives. Common network cards are supported. It is packaged as a bootable CD image with an ncurses GUI for easy use.
slapt-get is an APT-like system for Slackware package management. It allows you to search Slackware mirrors and third-party package sources (such as www.linuxpackages.net) for packages, compare them with installed packages, and install new packages or upgrade installed packages, all with a few simple commands.
Finnix is a small, self-contained, bootable Linux CD distribution ("LiveCD") for system administrators, based on Debian testing. You can use it to mount and manipulate hard drives and partitions, monitor networks, rebuild boot records, install other operating systems, and much more.
