12 years after the project was conceived, and after a long period in which it was useable though incomplete, FreeDOS has reached version 1.0. The ISO is downloadable at SourceForge. Versions with more extras should be available soon, as should a mail-order option.

"What follows is meant to be a hands-on introduction to system programming, using C and the Sartoris microkernel. Knowledge of the C programming language is assumed. This tutorial should have you writing, compiling and booting several little programs presto. In order to do this, you will need access to a *nix system and development tools. Linux is what we use over here, but if you are a windows user, Cygwin will do as well."

After bitter statements around Xen's maturity these last weeks from Red Hat, Novell, and XenSource itself, the company finally launched its first commercial product based on the open source hypervisor: XenEnterprise 1.0. The product adds commercial grade features and support to Xen 3.0. XenSource also built around it a sales channel infrastructure, a technical certification program, and a much discussed agreement with Microsoft.

Red Hat and Novell, the two top Linux sellers, have only just begun building Xen virtualization software into their products. But they're already planning to add a higher-level option. Xen is a 'hypervisor' that lets a single computer run several operating systems simultaneously, using an idea called 'virtualization'. This enables companies to use a single server more efficiently - something that could save them money. Now 'containers', a higher-level virtualization approach that makes a single operating system look like many, is also getting traction.

Version 0.63 of Visopsys was released today. It's a maintenance release with bugfixes and loads of small tweaks throughout the system, but also a few new little features, including the ability to format and resize Linux swap partitions, more reliable OS loading, better CPU detection, and a simple text editor. Detailed change log and downloads.

OneStat today reported that Microsoft's Windows dominates the operating system market with a global usage share of 96.97 percent. The Mac appears to be at around 2.47% and Linux at 0.36%. Please note that OneStat bases its numbers on a large number of internet site hits and extraction from user agents.

Between the full desktop version, the subscriber's ad-free version, the normal mobile version (via autodetection), the very lite mobile version and the WAP version of OSNews, here is one more: http://osnews.com/pda . This version is built around our RSS feed and it's geared towards cellphones (like the Motorola RaZR line) that can't quite manage to render our normal mobile front page (28 KB overall) while the very lite or WAP versions don't have enough information in them so they leave our readers with a bitter taste. Hence, we implemented this RSS-based middle-ground mobile version, like we also did for other popular sites yesterday (screenshots). The PHP source code that generates this mobile-friendly layout is freely available and ready to be deployed, courtecy of MoBits.com.

"All of you who are reading this article right now are doing so with the help of an operating system. Of course, if you're reading it on paper, then that you may not think that that's the case, although it had to be printed by a printer that was connected to a computer which was operated by an operating system, right? In a way, it's like playing Six Degrees of Kevin Bacon. When you get right down to it, operating systems are a major part of our connected lives since something is needed to manage and execute all of the actions that take place on the electronic devices that we love oh so very much."

VMware has announced a product designed to enable Mac OS X users to run multiple PC operating systems while Microsoft is putting a halt to a version of its Virtual PC software for Intel-based Macs.

In all appearance of an ad-supported operating system is probably not that far off. This article takes a look at some of the finer points behind an OS which is financed with ad views, and more specifically the logic behind a free version of Windows which could make this a reality. There are a few issues which must be resolved first, but with Microsoft refining Windows Live and shifting some of their focus to advertising, many of the pieces seem to be falling into place. A few years ago we featured an editorial and poll on the subject here at OSNews.

"Too many Linux image viewers are tinged with little annoyances - they take too long to load, are slow to redraw the display, have limited format support, sport inconvenient controls - so when you want to settle on one, inevitably there's something to make you utter feh! in general discontent. Good call - feh is the name of a speedy little viewer that packs a surprising number of features for its size."

Based on functionality alone, VMware's VMware Server 1.0 would merit serious consideration for inclusion in any developer or system administrator's tool kit. However, it's VMware Server's price - free - that propels this product from merely worth having to practically must-have. During tests, eWEEK Labs found VMware Server 1.0, which was released July 12, to be extremely useful for development, testing and deployment of applications - be they stand-alone or part of a complete operating-system-to-application stack.

Plan 9 is an operating system designed by the same people who created the original UNIX. Its development began in the late 1980's and it was a research project intended to address a variety of system scalability issues that the UNIX and LINUX kernels don't do particularly well, namely, distributed computing, distributed name spaces, and distributed file systems. Plan 9 is open source and its current and fourth major release was in 2002. It is available as an install or LiveCD and it can be downloaded here.

In its initial concept, OpenVMS (then VAX/VMS) sought to provide the functionality and capabilities of a mainframe-class system at a small fraction of the size and cost, while at the same time providing higher levels of reliability and integrity. These goals were achieved by what has become OpenVMS' hallmark, an emphasis on integrity and architectural leverage. Note: This is an entry to our OS Contest.
