Operating Systems

• Review of Operating Systems: This index favors original and research operating systems. In each category, systems are listed in alphabetical order
• Operating System Comparison: This web site compares and contrasts operating systems. It originally started out on a small server in the engineering department of Ohio State University to answer a single question: “On technical considerations only, how does Rhapsody (also known as Mac OS X Server) stack up as a server operating system (especially in comparison to Windows NT)?” The web site now compares and contrasts server operating systems and will in the near future expand to compare other kinds of operating systems.
• SIGOPS: SIGOPS addresses a broad spectrum of issues associated with operating systems research and development. Although many of the members are drawn from industry, academic and government professionals are also represented in the membership.

• Plex86.org :  The goal of the Plex86 project is to create an extensible open source PC virtualization software program that will allow PC, and workstation users to run multiple operating systems concurrently on the same machine. What makes it challenging on the PC, is that the x86 processor is not "naturally" virtualizable. That is to say, it was not designed to run multiple operating systems concurrently. However, with some manipulation and use of system level features, this can be done. The Plex86 environment makes the processor virtualization more flexible and controllable than commercial products where developers do not have access to the source code, such as VMware.

• System Toolbox : System Toolbox is a site dedicated to System Administrators.   We do not discriminate against any server operating systems here.  The idea behind the site is that most System Administrators are required to work with many different Server Operating Systems but there are not many resources available with this in mind.  This site aims to help out with informative discussions and tips towards a variety of platforms.
