The OpenBSD project's website.
The OpenBSD project produces a FREE, multi-platform 4.4BSD-based UNIX-like operating system. Our efforts emphasize portability, standardization, correctness, proactive security and integrated cryptography. OpenBSD supports binary emulation of most programs from SVR4 (Solaris), FreeBSD, Linux, BSD/OS, SunOS and HP-UX. OpenBSD is freely available from our FTP sites, and also available in an inexpensive 3-CD set.

The FreeBSD project's website.
FreeBSD is a UN*X-like operating system for the i386, IA-64, PC-98, Alpha/AXP, and UltraSPARC platforms based on U.C. Berkeley's "4.4BSD-Lite" release, with some "4.4BSD-Lite2" enhancements. It is also based indirectly on William Jolitz's port of U.C. Berkeley's "Net/2" to the i386, known as "386BSD", though very little of the 386BSD code remains. FreeBSD is used by companies, Internet Service Providers, researchers, computer professionals, students and home users all over the world in their work, education and recreation.
Debian GNU/kFreeBSD is an operating system released by the Debian project for i486-compatible computer architectures. It is a distribution of GNU with Debian package management and the kernel of FreeBSD. The k in kFreeBSD refers to the fact that only the kernel of the complete FreeBSD operating system is used.
The NetBSD project's website.
NetBSD is a free, secure, and highly portable UNIX-like Open Source operating system available for many platforms, from 64-bit AlphaServers and desktop systems to handheld and embedded devices. Its clean design and advanced features make it excellent in both production and research environments, and it is user-supported with complete source. Many applications are easily available through The NetBSD Packages Collection.
DragonFly is an operating system and environment originally based on FreeBSD. DragonFly branched from FreeBSD in 2003 in order to develop a radically different approach to concurrency, SMP, and most other kernel subsystems.DragonFly belongs to the same class of operating system as BSD and Linux and is based on the same UNIX ideals and APIs. DragonFly gives the BSD base an opportunity to grow in an entirely different direction from the one taken in the FreeBSD, NetBSD, and OpenBSD series.
PC-BSD is a complete desktop operating system, which has been designed with the "casual" computer user in mind. It offers the stability and security that only a BSD-based operating system can bring, while as the same time providing a comfortable user experience, allowing you to get the most out of your computing time. With PC-BSD you can spend less time working to fix viruses or spyware and instead have the computer work for you.
The OpenSolaris project is an open source project sponsored by Sun Microsystems, Inc, that is initially based on a subset of the source code for the Solaris Operating System. It is a nexus for a community development effort where developers from Sun and elsewhere can collaborate on developing and improving operating system technology. The OpenSolaris source code will find a variety of uses, including being the basis for future versions of the Solaris OS product, other operating system projects, and third-party products and distributions.
Nexenta OS is a computer operating system based on Debian/Ubuntu and Solaris for IA-32 and x86-64 based systems. It emerged in fall 2005, after Sun Microsystems started the OpenSolaris project in June 2005.

Object Oriented Programming in C (online book)
This paper presents some programming techniques that allow large projects based on ISO C89 to get the benefits of object oriented design. It doesn't intend to be a course on OOP techniques and assumes the reader to have a good knowledge of the C language. Since OOPC is based on the C++ Object Model, a good knowledge of C++ may help to understanding it better. These techniques may be useful for programmers who have not a C++ compiler for their architecture (calculators, small systems, embedded systems). It may also be useful for people who are disappointed by C++ compilers which do not behave like the norm says or even do not support all the C++ features or by C++ APIs that change from time to time.

The Debian GNU/Linux project's website.
The Debian Project is an association of individuals who have made common cause to create a free operating system. This operating system is called Debian GNU/Linux, or simply Debian for short. Debian systems currently use the Linux kernel. Linux is a completely free piece of software started by Linus Torvalds and supported by thousands of programmers worldwide. Of course, the thing that people want is application software: programs to help them get what they want to do done, from editing documents to running a business to playing games to writing more software. Debian comes with over 20,000 packages (precompiled software that is bundled up in a nice format for easy installation on your machine) - all of it free. It's a bit like a tower. At the base is the kernel. On top of that are all the basic tools. Next is all the software that you run on the computer. At the top of the tower is Debian -- carefully organizing and fitting everything so it all works together.
The openSUSE project is a community program sponsored by Novell. Promoting the use of Linux everywhere, this program provides free, easy access to openSUSE, a complete Linux distribution. The openSUSE project has three main goals: make openSUSE the easiest Linux for anyone to obtain and the most widely used Linux distribution; leverage open source collaboration to make openSUSE the world's most usable Linux distribution and desktop environment for new and experienced Linux users; dramatically simplify and open the development and packaging processes to make openSUSE the platform of choice for Linux developers and software vendors.
