Last month Eric Raymond suggested Microsoft might be moving to a Linux kernel that emulates Windows. ZDNet contributing editor Steven J. Vaughan-Nichols argued such a move "makes perfect sense", and open source advocate Jack Wallen even suggested Microsoft abandon Windows altogether for a new distro named Microsoft Linux.

It eventually drew the attention of Canonical's engineering manager for Ubuntu on WSL, who published a blog post with his own personal thoughts. Its title? "No, Microsoft is not rebasing Windows to Linux." The NT kernel in Windows offers a degree of backward compatibility, long-term support, and driver availability that Linux is just now approaching. It would cost millions of dollars to replicate these in Linux. Microsoft has plenty of paying customers to continue supporting Windows as-is, some for decades. Windows is not a drain on Microsoft that would justify the expense of rebasing to Linux for savings, as Raymond has argued... It is unclear if the Windows user space could even be rebased from NT to the Linux kernel and maintain the compatibility that Windows is known for, specifically what enterprise clients with mission-critical applications are paying to get....

Microsoft has doubled down on Windows in recent years. Microsoft has invested in usability, new features, and performance improvements for Windows 10 that have paid off. These improvements, collaborations with OEMs, and the Surface helped revitalize a PC market that at one point looked in danger of falling to iPads and Chromebooks... Internal reorganizations in 2018 and 2020 show that the future of the Surface and Windows are now inextricably linked. Windows powers the Xbox and we are in a resurgence of mostly Windows-based PC gaming. Microsoft also has ideas for Windows 10X, the next operating system concept following Windows 10 (that I think we will get in gradual pieces), with future hardware like the Surface Neo in mind...

The much more interesting question is not whether Microsoft is planning to rebase Windows to Linux, but how far Windows will go on open source. We are already seeing components like Windows Terminal, PowerToys, and other Windows components either begin life as or go open source. The more logical and realistic goal here is a continued opening of Windows components and the Windows development process, even beyond the Insiders program, in a way that benefits other operating systems...

Raymond is correct in one key part of his blog. I do think the era of the desktop OS wars is ending. We are entering a new era where your high-end workstation will run multiple operating systems simultaneously, like runtimes, and not necessarily all locally. The choice will not really be Windows or Linux, it will be whether you boot Hyper-V or KVM first, and Windows and Ubuntu stacks will be tuned to run well on the other. Microsoft contributes patches to the Linux kernel to run Linux well on Hyper-V and tweaks Windows to play nicely on KVM. The best parts of Ubuntu will come to Windows and the best open source parts of Windows will come to Ubuntu, thanks to an increasing trend towards open source across Microsoft.

The key take-away though is that open source has won. And Raymond can be proud of helping to articulate the case for the open source development model when he did.
The post also explores "the reasons why I think this fantasy this keeps cropping up on Slashdot and Hacker News," calling the idea "a long-held fantasy for open source and Linux advocates."

But instead he concludes "Neither Windows nor Ubuntu are going anywhere. They are just going to keep getting better through open source."

An anonymous reader shares a report: Earlier, Microsoft released the source for Windows Calculator. And now, that calculator app has been ported to Linux by Uno Platform. Best of all, it's insanely easy to install as it is packaged in Snap format. "The good folks in the Uno Platform community have ported the open-source Windows Calculator to Linux. And they've done it quicker than Microsoft could bring their browser to Linux. The calculator is published in the snapstore and can be downloaded right away," explains Rhys Davies, Product Manager, Canonical.

An anonymous reader quotes a report from Ars Technica: Google and Intel are warning of a high-severity Bluetooth flaw in all but the most recent version of the Linux Kernel. While a Google researcher said the bug allows seamless code execution by attackers within Bluetooth range, Intel is characterizing the flaw as providing an escalation of privileges or the disclosure of information. The flaw resides in BlueZ, the software stack that by default implements all Bluetooth core protocols and layers for Linux. Besides Linux laptops, it's used in many consumer or industrial Internet-of-things devices. It works with Linux versions 2.4.6 and later. So far, little is known about BleedingTooth, the name given by Google engineer Andy Nguyen, who said that a blog post will be published "soon." A Twitter thread and a YouTube video provide the most detail and give the impression that the bug provides a reliable way for nearby attackers to execute malicious code of their choice on vulnerable Linux devices that use BlueZ for Bluetooth.

Intel, meanwhile, has issued this bare-bones advisory that categorizes the flaw as privilege-escalation or information-disclosure vulnerability. The advisory assigned a severity score of 8.3 out of a possible 10 to CVE-2020-12351, one of three distinct bugs that comprise BleedingTooth. "Potential security vulnerabilities in BlueZ may allow escalation of privilege or information disclosure," the advisory states. "BlueZ is releasing Linux kernel fixes to address these potential vulnerabilities." Intel, which is a primary contributor to the BlueZ open source project, said that the most effective way to patch the vulnerabilities is to update to Linux kernel version 5.9, which was published on Sunday. Those who can't upgrade to version 5.9 can install a series of kernel patches the advisory links to. Maintainers of BlueZ didn't immediately respond to emails asking for additional details about this vulnerability. Ars Technica points out that since BleedingTooth requires proximity to a vulnerable device, there's not much reason for people to worry about this vulnerability. "It also requires highly specialized knowledge and works on only a tiny fraction of the world's Bluetooth devices," it adds.

KDE's Plasma 5.20 is now available, bringing a bunch of refinements as well as some larger features. Some of the KDE Plasma 5.20 highlights include (via Phoronix): - Numerous fixes to the KWin window manager / compositor including a number of Wayland fixes. Among the Wayland work in Plasma 5.20 includes Klipper support and middle-click paste, mouse and touchpad support nearly on par to X11, window thumbnails in the task manager, crash fixes, and more.

- Improved notifications.

- Different redesigns and additions to the KDE System Settings from SMART monitoring to better looking interfaces.

- Redesigned on-screen displays.

- Various tack manager and system tray improvements. More information about KDE 5.20 is available here.

FSGSBASE support in Linux "has the possibility of helping Intel/AMD CPU performance especially in areas like context switching that had been hurt badly by Spectre/Meltdown and other CPU vulnerability mitigations largely on the Intel side," Phoronix wrote back in August. As it started its journey into the kernel, they provided a preview on August 10: The FSGSBASE support that was finally mainlined a few days ago for Linux 5.9 is off to providing a nice performance boost for both Intel and AMD systems... FSGSBASE support for the Linux kernel has been around a half-decade in the making and finally carried over the finish line by one of Microsoft's Linux kernel engineers...

FSGSBASE particularly helps out context switching heavy workloads like I/O and allowing user-space software to write to the x86_64 GSBASE without kernel interaction. That in turn has been of interest to Java and others...On Linux 5.9 where FSGSBASE is finally mainlined, it's enabled by default on supported CPUs. FSGSBASE can be disabled at kernel boot time via the "nofsgsbase" kernel option.
Today on the Linux kernel mailing list, Linus Torvalds announced the release of Linux 5.9: Ok, so I'll be honest - I had hoped for quite a bit fewer changes this last week, but at the same time there doesn't really seem to be anything particularly scary in here. It's just more commits and more lines changed than I would have wished for.
And Phoronix reported: Linux 5.9 has a number of exciting improvements including initial support for upcoming Radeon RX 6000 "RDNA 2" graphics cards, initial Intel Rocket Lake graphics, NVMe zoned namespaces (ZNS) support, various storage improvements, IBM's initial work on POWER10 CPU bring-up, the FSGSBASE instruction is now used, 32-bit x86 Clang build support, and more. See our Linux 5.9 feature overview for the whole scoop on the many changes to see with this kernel.

Following up on speculation from Eric Raymond and ZDNet contributing editor Steven J. Vaughan-Nichols, open source advocate Jack Wallen imagines what would happen if Microsoft just switched over altogether from Windows to a Linux distro named "Microsoft Linux": A full-on Linux distribution released by Microsoft would mean less frustration for all involved. Microsoft could shift its development efforts on the Windows 10 desktop to a desktop that would be more stable, dependable, flexible, and proven. Microsoft could select from any number of desktops for its official flavor: GNOME, KDE, Pantheon, Xfce, Mint, Cinnamon... the list goes on and on. Microsoft could use that desktop as is or contribute to it and create something that's more in-line with what its users are accustomed to...

[U]sers would very quickly learn what it's like to work on a desktop computer and not have to deal with the daily frustrations that come with the Windows operating system. Updates are smoother and more trustworthy, it's secure, and the desktop just makes more sense. Microsoft has been doing everything in its power to migrate users from the standard client-based software to cloud and other hosted solutions, and its software cash cow has become web-centric and subscription-based. All of those Linux users could still work with Microsoft 365 and any other Software as a Service (SaaS) solution it has to offer — all from the comfort and security of the Linux operating system...

If Microsoft plays its cards right, the company could re-theme KDE or just about any Linux desktop in such a way that it's not all that different from the Windows 10 interface. Lay this out right, and consumers might not even know the difference — a "Windows 11" would simply be the next evolution of the Microsoft desktop operating system. Speaking of winning, IT pros would spend less time dealing with viruses, malware, and operating system issues and more time on keeping the network (and the servers powering that network) running and secure... Microsoft would be seen as finally shipping an operating system worthy of the consumer; the consumer would have a desktop operating system that didn't deliver as many headaches as it did moments of actual productivity and joy; and the Linux community would finally dominate the desktop.

Last week open-source advocate Eric S. Raymond argued Microsoft was quietly switching over to a Linux kernel that emulates Windows. "He's on to something," says ZDNet's contributing editor Steven J. Vaughan-Nichols: I've long thought that Microsoft was considering migrating the Windows interface to running on the Linux kernel. Why...? [Y]ou can run standard Linux programs now on WSL2 without any trouble.

That's because Linux is well on its way to becoming a first-class citizen on the Windows desktop. Multiple Linux distros, starting with Ubuntu, Red Hat Fedora, and SUSE Linux Enterprise Desktop (SLED), now run smoothly on WSL2. That's because Microsoft has replaced its WSL1 translation layer, which converted Linux kernel calls into Windows calls, with WSL2. With WSL2 Microsoft's own Linux kernel is running on a thin version of the Hyper-V hypervisor. That's not all. With the recent Windows 10 Insider Preview build 20211, you can now access Linux file systems, such as ext4, from Windows File Manager and PowerShell. On top of that, Microsoft developers are making it easy to run Linux graphical applications on Windows...

[Raymond] also observed, correctly, that Microsoft no longer depends on Windows for its cash flow but on its Azure cloud offering. Which, by the way, is running more Linux instances than it is Windows Server instances. So, that being the case, why should Microsoft keep pouring money into the notoriously trouble-prone Windows kernel — over 50 serious bugs fixed in the last Patch Tuesday roundup — when it can use the free-as-in-beer Linux kernel? Good question. He thinks Microsoft can do the math and switch to Linux.

I think he's right. Besides his points, there are others. Microsoft already wants you to replace your existing PC-based software, like Office 2019, with software-as-a-service (SaaS) programs like Office 365. Microsoft also encourages you to move your voice, video, chat, and texting to Microsoft's Azure Communication Services even if you don't use Teams. With SaaS programs, Microsoft doesn't care what operating system you're running. They're still going to get paid whether you run Office 365 on Windows, a Chromebook, or, yes, Linux.

I see two possible paths ahead for Windows. First, there's Linux-based Windows. It simply makes financial sense. Or, the existing Windows desktop being replaced by the Windows Virtual Desktop or other Desktop-as-a-Service (DaaS) offerings.... Google chose to save money and increase security by using Linux as the basis for Chrome OS. This worked out really well for Google. It can for Microsoft with — let's take a blast from the past — and call it Lindows as well.

"POSIX has been the standard file system interface for Unix-based systems (which includes Linux) since its launch more than 30 years ago," writes Enterprise Storage Forum, noting the POSIX-compliant Lustre file system "powers most supercomputers."

Now Slashdot reader storagedude writes: POSIX has scalability and performance limitations that will become increasingly important in data-intensive applications like deep learning, but until now it has retained one key advantage over the infinitely scalable object storage: the ability to process data in memory. That advantage is now gone with the new mmap_obj() function, which paves the way for object storage to become the preferred approach to Big Data applications.
POSIX features like statefulness, prescriptive metadata, and strong consistency "become a performance bottleneck as I/O requests multiply and data scale..." claims the article.

"The mmap_obj() developers note that one piece of work still needs to be done: there needs to be a munmap_obj() function to release data from the user space, similar to the POSIX function."

ZDNet reports: At the Microsoft Build 2020 virtual developers' conference, CEO Satya Nadella announced that Windows Subsystem for Linux (WSL) 2.0 would soon support Linux GUIs and applications. That day is closer now than ever before. At the recent X.Org Developers Conference, Microsoft partner developer lead Steve Pronovost revealed that Microsoft has made it possible to run graphical Linux applications within WSL.

It's always been possible to run Linux graphical programs such as the GIMP graphics editor, Evolution e-mail client, and LibreOffice on WSL. But it wasn't easy. You had to install a third-party X Window display server, such as the VcXsrv Windows X Server in Windows 10, and then do some tuning with both Windows and Linux to get them to work together smoothly. The X Window System underlies almost all Linux graphical user interfaces. Now, Microsoft has ported a Wayland display server to WSL. Wayland is the most popular X Window compatible server. In WSL2, it connects the graphical Linux applications via a Remote Desktop Protocol (RDP) connection to the main Windows display. This means you can run Linux and Windows GUI applications simultaneously on the same desktop screen....

Craig Loewen, Microsoft WSL Program Manager, added in a Twitter thread that the key differences between using a third-party X server and the built-in Wayland server is that: "You don't need to start up or start the server, we'll handle that for you." In addition, it comes with "Lovely integration with Windows," such as drop shadows and Linux icon support. Loewen also said you can run a Linux web browser in it. "We haven't tested it extensively with a full desktop environment yet, as we want to focus on running often asked for apps first, and primarily IDEs [integrated development environment] so you can run those in a full Linux environment," he said.

Don't get too excited about it just yet, though. Loewen continued, "We don't yet have an ETA for the beta channel, however, this work will be available in general for Insiders to try within the next couple of months."

An anonymous reader writes: Linux fans, Ubuntu 20.10 "Groovy Gorilla" Beta is now available for download. This doesn't just include the "vanilla" GNOME version either, but other variants like Kubuntu and Xubuntu as well. "20.10, codenamed 'Groovy Gorilla,' continues Ubuntu's proud tradition of integrating the latest and greatest open source technologies into a high quality, easy-to-use Linux distribution. The team has been hard at work through this cycle, introducing new features and fixing bugs," explains Åukasz Zemczak, Canonical.

Hobbyist developers are trying once again to get a Motorola 68000 back-end merged into the upstream LLVM compiler. Phoronix reports: The Motorola 68000 series processors have been around since the 80's thanks to the likes of the early Apple Macintosh computers. Fast forward to 2020, the Motorola 68000 is still a popular target for vintage computer enthusiasts and hobbyists. Community developers have worked on improving the Linux kernel support for M68k hardware like early Apple Powerbooks as recently as a few years ago and the compiler support is a continued target. GCC 11 due out next year was looking to drop the M68k target over its unmaintained status. Hobbyists though stepped up there so the M68k support will remain in GCC. Now developers are also looking at adding M68k support to the LLVM compiler.

This isn't the first time that M68k support for LLVM has been brought up albeit never successfully landed to date. Building off the past failures to get the Motorola 68000 series support upstreamed, developers last week sent out new patches proposing this back-end -- this time they are showing more clarity about the developers involved and being committed to supporting the code, the sustainability of the code, and responding quickly to code review comments. This patch series is the latest attempt at upstreaming Motorola 68000 series support in LLVM. Besides all the back-end specific code there is also some common LLVM code changes that fall under greater scrutiny.

The Xen Project has ported its hypervisor to the 64-bit Raspberry Pi 4. The Register reports: The idea to do an official port bubbled up from the Xen community and then reached the desk of George Dunlap, chairman of the Xen Project's Advisory Board. Dunlap mentioned the idea to an acquaintance who works at the Raspberry Pi Foundation, and was told that around 40 percent of Pis are sold to business users rather than hobbyists. With more than 30 million Arm-based Pis sold as of December 2019, and sales running at a brisk 600,000-plus a month in April 2020, according to Pi guy Eben Upton, Dunlap saw an opportunity to continue Xen's drive towards embedded and industrial applications.

Stefano Stabellini, who by day works at FPGA outfit Xilinx, and past Apache Foundation director Roman Shaposhnik took on the task of the port. The pair clocked that the RPi 4's system-on-chip used a regular GIC-400 interrupt controller, which Xen supports out of the box, and thought this was a sign this would, overall, be an easy enough job. That, the duo admitted, was dangerous optimism. Forget the IRQs, there was a whole world of physical and virtual memory addresses to navigate. The pair were "utterly oblivious that we were about to embark on an adventure deep in the belly of the Xen memory allocator and Linux address translation layers," we're told. [The article goes on to explain the hurdles that were ahead of them.]

"Once Linux 5.9 is out, we will have Xen working on RPi4 out of the box," the pair said. [...] Stefano Stabellini told The Register that an official Xen-on-RPi port will make a difference in the Internet-of-Things community, because other Arm development boards are more costly than the Pi, and programmers will gravitate towards a cheaper alternative for prototyping. He also outlined scenarios, such as a single edge device running both a real-time operating system alongside another OS, each dedicated to different tasks but inhabiting the same hardware and enjoying the splendid isolation of a virtual machine rather than sharing an OS as containers. George Dunlap also thinks that an official Xen-on-RPi port could also be of use to home lab builders, or perhaps just give developers a more suitable environment for their side projects than a virtual machine or container on their main machines. Stay tuned to Project EVE's Github page for more details about how to build your own Xen-for-RPi. Hacks to get it up and running should also appear on the Xen project blog.

The Linux Foundation has announced that its free Introduction to Linux training course on edX has surpassed one million enrollments. The course helps students develop a good working knowledge of Linux using both the graphical interface and command line across the major Linux distribution families. No prior knowledge or experience is required, making the course a popular first step for individuals interested in pursuing a career in IT.

Introduction to Linux has helped countless individuals launch their IT careers. Jules Bashizi Irenge for example, completed the course then proceeded to intermediate Essentials of System Administration training and received a Linux Foundation Certified SysAdmin (LFCS) certification, and now is a PhD candidate who has contributed over 200 patches to the Linux kernel. Fabian Pichardo also followed the introductory course with Essentials of System Administration and LFCS, and now is employed full time as a software developer.

"To have introduced over a million individuals to Linux is a tremendous milestone," said Linux Foundation Executive Director Jim Zemlin. "One of our primary goals is to bring more talent into the open source community, and offering free, high quality training that is accessible to anyone who wants it is essential to achieving that goal...."

The Linux Foundation has been an incredible partner of edX for the past six years, bringing dozens of courses in high-tech and in-demand fields to our platform of 34 million learners," said Anant Agarwal, edX Founder and CEO. "Introduction to Linux, their very first offering, has been a true blockbuster - it's one of our top 10 most popular courses of all time. We're thrilled to congratulate Linux Foundation on reaching 1 million enrollments and look forward to bringing accessible high-tech education to countless more learners, together."

Introduction to Linux remains open for new enrollments. There is no cost to complete the course, and verified certificates of completion are available for $99. The Linux Foundation offers two dozen free training courses on open source projects including Linux, Kubernetes, Hyperledger, and more in partnership with edX.

"More top-tier computer OEMs are now offering a broad assortment of Linux desktops," reports ZDNet.

"In the latest move, Lenovo, currently the top PC vendor in the world according to Gartner, will roll Ubuntu Linux 20.04 LTS out across 30 of Lenovo's ThinkPads and ThinkStations..." While Lenovo started certifying most of its laptop and PC line on the top Linux distributions since June 2020, this is a much bigger step. Now, instead of simply acknowledging its equipment will be guaranteed to run Linux, Lenovo's selling Ubuntu Linux-powered hardware to ordinary Joe and Jane users.

Previously, you could only buy most of these machines if you were a business and had specified you wanted Ubuntu on a customized bid. Now, nearly 30 Ubuntu-loaded devices will now be available for purchase via Lenovo.com. These include 13 ThinkStation and ThinkPad P Series Workstations and an additional 14 ThinkPad T, X, X1, and L series laptops, all with the 20.04 LTS version of Ubuntu...

No one's predicting a "Year of the Linux desktop." Companies such as Dell and Lenovo aren't predicting such a game-changing event, but they're selling largely to enterprise companies, which have seen the virtues of using high-end Linux desktops for powerful, forward-looking technologies such as AI, ML, containers, and cloud-native computing.
"Our announcement of device certification in June was a step in the right direction to enable customers to more easily install Linux on their own," explains Lenovo's vice president of PCSD software and cloud — but now they're going even further.

"Our goal is to remove the complexity and provide the Linux community with the premium experience that our customers know us for. This is why we have taken this next step to offer Linux-ready devices right out of the box."

Most of Microsoft's money now comes from its cloud service Azure, points out open-source advocate Eric S. Raymond. Now he posits a future where Windows development will "inevitably" become a drag on Microsoft's business: So, you're a Microsoft corporate strategist. What's the profit-maximizing path forward given all these factors? It's this: Microsoft Windows becomes a Proton-like emulation layer over a Linux kernel, with the layer getting thinner over time as more of the support lands in the mainline kernel sources. The economic motive is that Microsoft sheds an ever-larger fraction of its development costs as less and less has to be done in-house. If you think this is fantasy, think again. The best evidence that it's already the plan is that Microsoft has already ported Edge to run under Linux. There is only one way that makes any sense, and that is as a trial run for freeing the rest of the Windows utility suite from depending on any emulation layer.

So, the end state this all points at is: New Windows is mostly a Linux kernel, there's an old-Windows emulation over it, but Edge and the rest of the Windows user-land utilities don't use the emulation. The emulation layer is there for games and other legacy third-party software. Economic pressure will be on Microsoft to deprecate the emulation layer... Every increment of Windows/Linux convergence helps with that — reduces administration and the expected volume of support traffic.

Eventually, Microsoft announces upcoming end-of-life on the Windows emulation. The OS itself , and its userland tools, has for some time already been Linux underneath a carefully preserved old-Windows UI. Third-party software providers stop shipping Windows binaries in favor of ELF binaries with a pure Linux API...

...and Linux finally wins the desktop wars, not by displacing Windows but by co-opting it. Perhaps this is always how it had to be.

Long-time Slashdot reader Bismillah quotes iTnews: A software engineer in Melbourne is whiling away the city's lockdown by creating a tool that DOS users so far have lacked: an integrated Linux environment similar to what Windows 10 users enjoy...

"I first started out just seeing if I could get Linux booting from the DOS command line, and that turned out to be straightforward enough so I thought it'd be fun to see if I could continue executing DOS once Linux was running," Charlie Somerville said. "I'm mostly surprised by how smoothly the whole thing works given how *dodgy* it all is haha," he added. DOS Subsystem for Linux runs a real copy of MS-DOS under the QEMU virtual machine, and starts up from that, Somerville said...

"Helpfully Linux seems to leave the first megabyte of memory (where DOS lives) intact during its own boot process, so it's just a matter of jumping back to the right place to continue DOS execution," he added. Somerville had it pointed out to him that this approach of running DOS under vm8086 is actually how early Windows worked.

"Kinda cool to rediscover the technique so many years later," Somerville said.

On August 7, 2019, Linux Journal laid off all staff members and was left with no operating funds to continue in any capacity.

Krystalo writes: Edge is finally coming to Linux. At Ignite 2020 today, Microsoft announced that Edge for Linux will be available in the Dev preview channel starting in October. Linux users will be able to download the preview from the Microsoft Edge Insider website or from their native Linux package manager. Microsoft will start with the Ubuntu and Debian distributions, with support for Fedora and openSUSE coming afterwards. "Linux stands out in that, while it has a relatively small desktop population in terms of what you might call typical consumer or end user, developers are often overrepresented in that population, and especially in areas like test automation, or CI/CD workloads for their web apps," Edge program manager Kyle Pflug told VentureBeat. "Edge on Linux is a natural part of our strategy to reduce fragmentation and test overhead for web developers. By providing the same rendering behavior and tools across platforms, developers can build and test sites and web apps in their preferred environment and be confident in the experience their customers will have."

AmiMoJo writes: The GNOME 3 desktop environment was officially released in 2011, and in 2020 we are still on version 3.x. Yeah, despite many massive changes over the last (almost) decade, we have been stuck with point releases for GNOME 3. For instance, just last week, GNOME 3.38 was released. Historically, the stable releases all ended in even numbers, with pre-release versions ending in odd. For fans of the DE, such as yours truly, we have simply learned to live with this odd versioning scheme. Well, folks, with the next version of GNOME, the developers have finally decided to move on from version 3.x. You are probably thinking the new version will be 4.0, but you'd be very wrong. Actually, following GNOME3.38 will be GNOME 40. "After nearly 10 years of 3.x releases, the minor version number is getting unwieldy. It is also exceedingly clear that we're not going to bump the major version because of technological changes in the core platform, like we did for GNOME 2 and 3, and then piling on a major UX change on top of that. Radical technological and design changes are too disruptive for maintainers, users, and developers; we have become pretty good at iterating design and technologies, to the point that the current GNOME platform, UI, and UX are fairly different from what was released with GNOME 3.0, while still following the same design tenets," says Emmanuele Bassi, The GNOME Foundation.

"Microsoft has submitted a series of patches to Linux kernel developers," reports ZDNet, "requesting that Linux run as the root partition on the Hyper-V, its hypervisor software for running Windows and non-Windows instances on hardware." Microsoft "wants to create a complete virtualization stack with Linux and Microsoft Hypervisor", according to Microsoft principle software engineer Wei Liu. Liu has proposed an RFC or request for comment that for now merely implements what are only the "absolutely necessary components to get things running... There will be a subsequent patch series to provide a device node (/dev/mshv) such that userspace programs can create and run virtual machines. We've also ported Cloud Hypervisor over and have been able to boot a Linux guest with Virtio devices since late July." Cloud Hypervisor is an experimental open-source hypervisor implementation from Intel written in the Rust programming language. It's a virtual-machine monitor that runs on top of KVM, the Kernel-based Virtual Machine hypervisor in the Linux kernel that's designed for cloud workloads...

Liu points out three more changes beyond amendments to the Hyper-V Top-Level Functional Specification. For example, Microsoft wants Linux to set up existing Hyper-V facilities differently. It also wants Linux kernel developers to change the kernel's behavior when accessing hardware memory in a way that affects driver access to the GPU and CPU that's being managed by an operating system memory manager. It's this issue that Microsoft engineers are least confident about and are asking for Linux developer support, according to Liu....

As Microsoft's executive VP of the cloud and enterprise group, Scott Guthrie, told ZDNet last year, Microsoft's shift to Linux and open source started over a decade ago when it open-sourced ASP.NET. "We recognized open source is something that every developer can benefit from. It's not nice, it's essential. It's not just code, it's community," explained Guthrie.
