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.
FreeNOS is an experimental microkernel operating system for learning purposes. The system is very experimental, yet it currently supports virtual memory, simple task scheduling, and interprocess communication (IPC). It currently contains support for a few devices, including VGA, keyboard, i8250 serial, ATA drives, and PCI controllers. FreeNOS has an experimental implementation of several filesystems, such as the virtual file system, procfs, tmpfs, linnfs, and ext2fs. Current application libraries include libposix, libc, libteken (terminal emulation), and libexec (executable formats). All source code has been documented with Doxygen tags. It has been tested on recent versions of Qemu, VMWare, VirtualBox, Bochs, and bare hardware.
Gentoo Linux is a versatile and fast Linux distribution for x86, PowerPC, Sparc, and Sparc64 that's geared towards Linux power users. Unlike other distros, it has an advanced package management system called Portage. Portage is a true ports system in the tradition of BSD ports, but is Python-based and sports a number of advanced features including dependencies, fine-grained package management, "fake" (OpenBSD-style) installs, path sandboxing, safe unmerging, system profiles, virtual packages, config file management, and more.
ProviderTool Internet server administration program with email protection. The software is divided into a subcomponent Admin Tool, Customer Tool, and a Reseller Tool. Each subcomponent tool manages a separate zone that is setup for the specific needs of your administrator, end user, and reseller. If you have a Red Hat, SuSE, or Debian Internet or intranet server, you will be able to add, delete, and change settings and users with just a couple of clicks. ProviderTool is delivered with a separate Apache and PHP server environment. There is also an email protection tool included.
cw is a non-intrusive real-time ANSI color wrapper for common Unix-based commands. It is designed to simulate the environment of the commands being executed, so that if a person types 'du', 'df', 'ping', etc. in their shell it will automatically color the output in real-time according to a definition file containing the color format desired. It has support for wildcard match coloring, tokenized coloring, headers/footers, case scenario coloring, command-line- dependent definition coloring, and includes over 50 pre- made definition files.
EPOR is an extensible package organiser for Unix-like systems. It's written to trace filesystem changes (something being installed) and save this information in a simple text database (this, as any other provided feature, is customisable via the embedded Guile interpreter). Database entries contain information supplied by the command line (package name, version, etc.) and traced by filesystem changes (new directories, files, etc.). This is achieved using the "LD_PRELOAD method''.
