Kernel Designs Explained

I wrote the following article for university. It tries to explain the difference between three kernel types in such a way that less-computer savvy people should understand it. I had a 1500 word limitation, so detailed elaborations were out of the question. "In this article, I will try to make the 'microkernel vs. monolithic kernel' debate more accessible and understandable for laymen. I will explain the purpose of a kernel, after which I will detail the differences between the two competing designs. Finally, I will introduce the hybrid design, which aims to combine the two. In the conclusion, I will argue that this hybrid design is the most common kernel type in the world of personal computers today." Because of the limitations, this article contains little news for most of you. Still, I thought I'd share.

BeOS Max Edition v4 Beta Released

After a short period of development, today Vasper released a first beta of BeOS Max 4. Max is a 'distribution' of the free personal edition of BeOS R5, originally released 6 years ago by Be Inc. Vasper started working on BeOS Max long before Zeta came to life and in the years after Be closed down it was of the two actively developed systems, to other being Developer edition also based on PE. Get BeOS 5 PE Max V4 beta 1 here, a development report is viewable here.

KDE 4.0 Release Schedule Finalised

The KDE Community and the release team have put together a release plan for the long anticipated version 4.0, which is planned to be released in October 2007. KDE 4.0 will likely contain initial versions of all the major subsystems that have been described in recent Dot articles. These 'Pillars' of KDE set the stage for desktop and application growth and maturity over the life of the KDE 4 series.

Microsoft Bows to EU, Makes Comm Protocols Public

Microsoft is making key communications protocols available for license, so that third parties, including competitors, can link into the company's newest enterprise products. Some are available immediately. The list of available protocols, XML schemas and application programming interfaces include transport protocols for communications between Office Outlook 2007 and Exchange Server 2007.

The Torvalds Transcript

LWN writes about a InformationWeek interview to Linus Torvalds: "Finally, the real basic issue is that I think the Free Software Foundation simply doesn't have goals that I can personally sign up to. For example, the FSF considers proprietary software to be something evil and immoral. Me, I just don't care about proprietary software. It's not 'evil' or 'immoral', it just doesn't matter. I think that Open Source can do better, and I'm willing to put my money where my mouth is by working on Open Source, but it's not a crusade - it's just a superior way of working together and generating code."

Windows Applications in Ubuntu with a Seamless Desktop

Virtualization of operating systems used to be slow and hard to use. Advances such as the KQemu accelerator, VirtualBox, VMWare, Xen and of course the recent integration of KVM virtualization into the Linux kernel have helped out a lot though, especially on the server side, but for a normal user, virtualization could be somewhat clunky. Mac users have been able to run their Windows applications like this using Parallels Coherence, yet now other *nix users can too. Ordinary desktop or business users who require applications from another operating system can benefit from a seamless desktop.

Mac Sales up or Down This Quarter?

If you ever needed more proof that statistics are about as bendable as a string of cotton, here it is. While various Mac websites report that Mac sales in this quarter 'may beat estimates', eWeek reports that 'a dip in Mac sales on the horizon'. Turns out they are both right, as analysts expect sales to be 5-10% short of expectations. eWeek just interprets them differently. Elsewhere, Mossberg has the first review of the Apple TV.

Where, oh Where, Is the GPLv3?

Almost two years ago, the FSF started work on the first update of the GNU GPL in over a decade. A last-minute hitch, though, is keeping the license from appearing. According to Peter Brown, the FSF's executive director, "We continue to work on the details of the GPLv3 as it relates to the situation presented by the Novell and Microsoft deal. We are researching issues related to potential unintended consequences of the language we plan to adopt. As soon as we are satisfied with the results of our research we plan to bring forward the next draft."

Computing Pioneer John Backus Dies at 82

John Backus, whose development of the Fortran programming language in the 1950s changed how people interacted with computers and paved the way for modern software, has died. He was 82. Backus died Saturday in Ashland, Oregon, according to IBM, where he spent his career. Prior to Fortran, computers had to be meticulously 'hand-coded' - programmed in the raw strings of digits that triggered actions inside the machine. Fortran was a 'high-level' programming language because it abstracted that work - it let programmers enter commands in a more intuitive system, which the computer would translate into machine code on its own.

OLPC Comes up with Stable Linux Build

The One Laptop Per Child program reported today that after 303 builds, it finally has a satisfactory version of its Red Hat Linux-based Sugar operating system that is considered stable, according to OLPC president for software and content Walter Bender. "After a final few bugs that had hidden in corners were driven into the light, we issued Stable Build 303 along with Q2B76 firmware this week," Bender said in his weekly email report.

Dell, Linux, and Mark Shuttleworth

A few weeks back Dell invited ideas from the world at large about what it should put on sale - in other words, what did the so-called 'community' want? It turned out that the 'community' wanted PCs installed with GNU/Linux. But the company has done nothing afterwards. Now, we have a staunch defence of Dell's position by Mark Shuttleworth, the proprietor of Canonical which owns the Ubuntu project.

‘How Apple Orchestrated Web Attack on Researchers’

"Last summer, when I wrote 'Vicious orchestrated assault on MacBook wireless researchers', it set off a long chain of heated debates and blogs. I had hoped to release the information on who orchestrated the vicious assault, but threats of lawsuits and a spineless company that refused to defend itself meant I couldn't disclose the details. A lot has changed since then: Researcher David Maynor is no longer working for SecureWorks, and he's finally given me permission to publish the details."

ReactOS: an Open Source OS Platform for Learning

"The ReactOS operating system has been in development for over eight years and aims to provide users with a fully functional and Windows-compatible distribution under the GPL license. ReactOS comes with its own Windows 2003-based kernel and system utilities and applications, resulting in an environment identical to Windows, both visually and internally. This talk will introduce the ReactOS project, as well as the various software engineering challenges behind it."

Novell Preps SUSE Enterprise Linux 10 SP1

"Novell will soon release a major upgrade to its SUSE Enterprise Linux 10 line. The enhancements, announced at the company's annual BrainShare tradeshow, will be rolled out in the form of the operating system's first service pack: SP1. 'Service packs' usually consist of bug-patches, with few major changes. Like Microsoft with its SP2 patch to Windows XP, however, Novell has elected to make major improvements with this approach. SUSE Linux Enterprise 10 includes SLES and SLED."

Creating a Sane Beryl Settings Manager

The Beryl project has won a lot of press time so far with its impressive tricks -- even more than its slower-evolving daddy, Compiz. There are several lose ends to Beryl's core engine and incompatibilities with existing applications or technologies. However, something that really put off a lot of people when they try Beryl is its dreadful settings manager.

The Nuclear Option in FLOSS

The FLOSS Movement is not yet recognized enough to develop peacefully. There are many obstacles in the way of its expansion: either internal (e.g. lack of standards) or external (e.g. stubborn hardware manufacturers). Those problems could be gradually overcome in a relatively short period of time but a question arises: What will happen if the paranoia wins?

Review: Zeta 1.5

In July 2005, OSNews reviewed the 1.0 version of what was then YellowTAB Zeta. I concluded: "I have a clear-cut impression of what Zeta R1 is: it is by far the best 'distribution' of BeOS currently available. The hardware support is, when compared to r5, significantly better. Stability-wise, Zeta R1 is a huge leap forward when compared to older versions. Some areas still need work; but they are mostly minor things, nothing that will stop you from using this operating system as your full-time, primary system." A lot has changed over the past 15 months; YellowTAB went belly-up, Magnussoft took over the development of Zeta, and to top it off, Zeta went multiuser. Not too long ago, Mangussoft released Zeta 1.5; here is my review.
