A year after releasing the first preview build of its Chromium-based Edge browser for Linux, Microsoft is announcing its general availability. From a report: The new release supports a variety of Linux distributions, including Ubuntu, Debian, Fedora and openSUSE. Microsoft announced Linux on Edge's availability milestone during the first day of its Ignite IT Pro conference. As of the release of Edge for Linux to the "stable" (mainstream user) channel, Edge is now available on Windows, Mac, iOS, Android and Linux. As it did when introducing the new Edge on macOS, Microsoft has been positioning Edge on Linux as more of an offering for IT pros and developers who want to test web sites than as a browser for "normal" users on those platforms. However, any user on any supported platform can use the new Edge.

Phoronix ran some fun performance tests this week. "Now that Windows 11 has been out as stable and the initial round of updates coming out, I've been running fresh Windows 11 vs. Linux benchmarks for seeing how Microsoft's latest operating system release compares to the fresh batch of Linux distributions." First up is the fresh look at the Windows 11 vs. Linux performance on an Intel Core i9 11900K Rocket Lake system... The Windows 11 performance was being compared to all of the latest prominent Linux distributions, including:

- Ubuntu 20.04.3 LTS
- Ubuntu 21.10
- Arch Linux (latest rolling)
- Fedora Workstation 35
- Clear Linux 35150

[...] Each operating system was cleanly installed and then run at its OS default settings for seeing how the out-of-the-box OS performance compares for these five Linux distributions to Microsoft Windows 11 Pro...

The geometric mean for all 44 tests showed Linux clearly in front of Windows 11 for this current-generation Intel platform. Ubuntu / Arch / Fedora were about 11% faster overall than Windows 11 Pro on this system. Meanwhile, Clear Linux was about 18% faster than Windows 11 and enjoyed about 5% better performance overall than the other Linux distributions.
Out of 44 tests, here's a breakdown of how many first-place wins were scored by each OS:

• Clear Linux: 33 (75%)
• Fedora Workstation 35: 4 (9.1%)
• Windows 11 Pro: 3 (6.8%)
• Ubuntu 20.04.3 LTS: 2 (4.5%)
• Arch Linux: 1 (2.3%)
• Ubuntu 21.10: 1 (2.3%)

Phoronix: Now that Windows 11 has been out as stable and the initial round of updates coming out, I've been running fresh Windows 11 vs. Linux benchmarks for seeing how Microsoft's latest operating system release compares to the fresh batch of Linux distributions. First up is the fresh look at the Windows 11 vs. Linux performance on an Intel Core i9 11900K Rocket Lake system. Microsoft Windows 11 Pro with all stable updates as of 18 October was used for this round of benchmarking on Intel Rocket Lake. The Windows 11 performance was being compared to all of the latest prominent Linux distributions, including: Ubuntu 20.04.3 LTS, Ubuntu 21.10, Arch Linux (latest rolling), Fedora Workstation 35, Clear Linux 35150. All the testing was done on the same Intel Core i9 11900K test system at stock speeds (any frequency differences reported in the system table come down to how the information is exposed by the OS, i.e. base or turbo reporting) with 2 x 16GB DDR4-3200 memory, 2TB Corsair Force MP600 NVMe solid-state drive, and an AMD Radeon VII graphics card.

Each operating system was cleanly installed and then run at its OS default settings for seeing how the out-of-the-box OS performance compares for these five Linux distributions to Microsoft Windows 11 Pro. But for the TLDR version... Out of 44 tests run across all six operating systems, Windows 11 had just three wins on this Core i9 11900K system. Meanwhile Intel's own Clear Linux platform easily dominated with coming in first place 75% of the time followed by Fedora Workstation 35 in second place with first place finishes 9% of the time. The geometric mean for all 44 tests showed Linux clearly in front of Windows 11 for this current-generation Intel platform. Ubuntu / Arch / Fedora were about 11% faster overall than Windows 11 Pro on this system. Meanwhile, Clear Linux was about 18% faster than Windows 11 and enjoyed about 5% better performance overall than the other Linux distributions.

Pine64 today announced its latest Linux-powered device, the PinePhone Pro, an update to the original PinePhone which sees a more powerful device running mainline Linux (Manjaro in this case) on a mobile device that works as a cellphone and a desktop computer. Tom's Hardware reports: This combination of hardware and software makes the still slightly futuristic idea of confluence between mobile and desktop devices seem a step closer. Carry it around with you, and it's a phone. Plug it into a monitor, and it's a desktop PC. The KDE Plasma Mobile front-end adapts to the circumstances. Inside, it's much like any other phone, with a Rockchip RK3399S six-core SoC operating at 1.5GHz, 4GB of dual-channel LPDDR4 RAM, and 128GB of internal eMMC flash storage. It features a 13MP main camera sensor and a 5MP front-facing camera. There's a Micro-SD slot for expanded storage, and a six-inch 1440 x 720 IPS touchscreen. The PinePhone Pro is not a typical cell phone, rather the concept of convergence, the ability to use your phone as a computer is intriguing. Plug your PinePhone Pro into an external display and use it as a low-power desktop computer is something that has been attempted by a number of companies, including Canonical's attempt with Ubuntu Edge.

PinePhone Pro offers something that is missing from the majority of phones, privacy. A series of hardware DIP-switches, hidden under a rear cover, cut off access to the cameras, microphone, Wi-Fi 5 and Bluetooth 4.1 chips, headphone jack, and LTE modem (including GPS) should you ever need to. The layout and Pogo Pins of the new phone are identical to the original PinePhone, so all existing accessories should work. Retailing at $399, the PinePhone Pro's makers are realistic about the challenges of putting desktop Linux on a mobile device, especially in an ecosystem dominated by iOS and Android.

Following a brief beta-testing period, Ubuntu 21.10 has finally become available to download in the "final" stable form. BetaNews: Code-named "Impish Indri," this version of Ubuntu is not a Long Term Support (LTS) version, so it is only supported for nine months. Ubuntu 21.10 features Linux kernel 5.13 and a Snap variant of the Mozilla Firefox browser. "Ubuntu 21.10 brings the all-new PHP 8 and GCC 11 including full support for static analysis, greatly improving everyday developer security awareness in low-level programming. With Gnome 40 desktop users gain dynamic workspaces and touchpad gestures. The new Firefox snap, published by Mozilla, improves security and guarantees access to both the latest and the extended support release versions of the browser. The exact same versions of the browser are available on multiple different versions of Ubuntu, simplifying enterprise developer platform management," says Canonical.

The best part of Windows 11 is Linux, argues Ars Technica: For years now, Windows 10's Windows Subsystem for Linux has been making life easier for developers, sysadmins, and hobbyists who have one foot in the Windows world and one foot in the Linux world. But WSL, handy as it is, has been hobbled by several things it could not do. Installing WSL has never been as easy as it should be — and getting graphical apps to work has historically been possible but also a pain in the butt that required some fairly obscure third-party software. Windows 11 finally fixes both of those problems. The Windows Subsystem for Linux isn't perfect on Windows 11, but it's a huge improvement over what came before.

Microsoft has traditionally made installing WSL more of a hassle than it should be, but the company finally got the process right in Windows 10 build 2004. Just open an elevated Command prompt (start --> type cmd --> click Run as Administrator), type wsl --install at the prompt, and you're good to go. Windows 11, thankfully, carries this process forward unchanged. A simple wsl --install with no further arguments gets you Hyper-V and the other underpinnings of WSL, along with the current version of Ubuntu. If you aren't an Ubuntu fan, you can see what other easily installable distributions are available with the command wsl --list --online. If you decide you'd prefer a different distro, you can install it instead with — for example — wsl --install -d openSUSE-42. If you're not sure which distribution you prefer, don't fret. You can install as many as you like, simply by repeating wsl --list --online to enumerate your options and wsl --install -d distroname to install whichever you like. Installing a second distribution doesn't uninstall the first; it creates a separate environment, independent of any others. You can run as many of these installed environments as you like simultaneously, without fear of one messing up another.

In addition to easy installation, WSL on Windows 11 brings support for both graphics and audio in WSL apps. This isn't exactly a first — Microsoft debuted WSLg in April, with Windows 10 Insider Build 21364. But Windows 11 is the first production Windows build with WSLg support. If this is your first time hearing of WSLg, the short version is simple: you can install GUI apps — for example, Firefox — from your Ubuntu (or other distro) command line, and they'll work as expected, including sound. When I installed WSLg on Windows 11 on the Framework laptop, running firefox from the Ubuntu terminal popped up the iconic browser automatically. Heading to YouTube in it worked perfectly, too, with neither frame drops in the video nor glitches in the audio....

[T]here is one obvious "killer app" for WSLg that has us excited — and that's virt-manager, the RedHat-originated virtualization management tool. virt-manager is a simple tool that streamlines the creation, management, and operation of virtual machines using the Linux Kernel Virtual Machine... virt-manager never got a Windows port and seems unlikely to. But it runs under WSLg like a champ.
They reported a few problems, like when running GNOME's Software Center app (and the GNOME shell desktop environment).

But "If you're already a Windows Subsystem for Linux (WSL) user, Windows 11 offers an enormously improved experience compared to what you're accustomed to from Windows 10. It installs more easily, makes more functionality available, and offers better desktop integration than older workarounds such as running MobaXTerm's X11 server."

Canonical has announced that it is extending the life of Ubuntu 14.04 and 16.04 to a decade. BetaNews: In other words, Ubuntu 14.04 and 16.04 are getting longer Extended Security Maintenance (ESM) periods as Canonical pushes back their End of Life (EoL) dates. The former will now get security updates until 2024, while the latter will receive them until 2026. "This lifecycle extension enables organizations to balance their infrastructure upgrade costs, by giving them additional time to implement their upgrade plan. The prolonged Extended Security Maintenance (ESM) phase of Ubuntu 14.04 LTS and 16.04 LTS enables a secure and low-maintenance infrastructure with security updates and kernel livepatches provided by Canonical. The announcement represents a significant opportunity for the organizations currently implementing their transition to new applications and technologies," says Canonical.

"2021 Is the Year of Linux on the Desktop," writes PC Magazine. "No, really..." Walk into any school now, and you'll see millions of Linux machines. They're called Chromebooks. For a free project launched 30 years ago today by one man in his spare time, it's an amazing feat.... Linux found its real niche — not as a political statement about "free software," but as a practical way to enable capable, low-cost machines for millions...

Chrome OS and Android are both based on the Linux kernel. They don't have the extra GNU software that distributions like Ubuntu have, but they're descended from Linus Torvalds' original work. Chromebooks are the fastest growing segment of the traditional PC market, according to Canalys. IDC points out that Canalys' estimates of 12 million Chromebooks shipped in Q1 2021 are only a fraction of the 63 million notebooks sold that quarter, but once again, they're where the growth is. Much of that is driven by schools, where Chromebooks dominate now. Schoolkids don't generally need a million apps' worth of generic computing power. They need inexpensive, rugged ways to log into Google Classroom. Linux came to the rescue, enabling cheap, light, easy-to-manage PCs that don't have the Swiss Army Knife cruft of Windows or the premium price of Macs...

One great thing about open-source hacker projects is that they can be taken in unexpected directions. Linux isn't controlled, so it can adapt, Darwinian-style. It was a little scurrying mammal in the time of the dinosaurs, and then the mobile-computing asteroid hit. Linux could evolve. Windows couldn't. When you're building something that fits in your hand and has to sip battery, you can't just keep throwing processors and storage at it. Microsoft had a tough time adapting its monstrous megakernel OS to the new, tiny world. But *nix platforms thrive there: Android (based on Linux) and iOS.
"Android and Chrome water down the Linux philosophy," the article argues, "but they are Linux..."

Does this make any long-time geeks feel vindicated? In the original submission wiredog (Slashdot reader #43,288) looks back to 1995, remembering that "my first Linux was RedHat 2.0 in the beige box, running the 0.95(?) kernel and the F Virtual Window Manager...

"It came with 2 books, a CD, and a boot floppy disk."

LTTng has been called "the killer app for system-level debugging and performance tuning." And now long-time Slashdot reader compudj writes: It's the official release of LTTng 2.13 — Nordicité! LTTng is a kernel and user-space tracer for Linux. The most notable features of this release are:

- Event-rule matches condition triggers and new actions, allowing internal actions or external monitoring applications to quickly react when kernel or user-space instrumentation is hit

- Notification payload capture, allowing external monitoring applications to read elements of the instrumentation payload when instrumentation is hit.

- Instrumentation API: vtracef and vtracelog (LTTng-UST)

- User space time namespace context (LTTng-UST and LTTng-modules).

An anonymous reader quotes a report from ZDNet, written by Steven J. Vaughan-Nichols: Microsoft now has its very own, honest-to-goodness general-purpose Linux distribution: Common Base Linux, (CBL)-Mariner. And, just like any Linux distro, you can download it and run it yourself. Microsoft didn't make a big fuss about releasing CBL-Mariner. It quietly released the code on GitHub and anyone can use it. Indeed, Juan Manuel Rey, a Microsoft Senior Program Manager for Azure VMware, recently published a guide on how to build an ISO CBL-Mariner image. Before this, if you were a Linux expert, with a spot of work you could run it, but now, thanks to Rey, anyone with a bit of Linux skill can do it.

CBL-Mariner is not a Linux desktop. Like Azure Sphere, Microsoft's first specialized Linux distro, which is used for securing edge computing services, it's a server-side Linux. This Microsoft-branded Linux is an internal Linux distribution. It's meant for Microsoft's cloud infrastructure and edge products and services. Its main job is to provide a consistent Linux platform for these devices and services. Just like Fedora is to Red Hat, it keeps Microsoft on Linux's cutting edge. CBL-Mariner is built around the idea that you only need a small common core set of packages to address the needs of cloud and edge services. If you need more, CBL-Mariner also makes it easy to layer on additional packages on top of its common core. Once that's done, its simple build system easily enables you to create RPM packages from SPEC and source files. Or, you can also use it to create ISOs or Virtual hard disk (VHD) images.

As you'd expect the basic CBL-Mariner is a very lightweight Linux. You can use it as a container or a container host. With its limited size also comes a minimal attack surface. This also makes it easy to deploy security patches to it via RPM. Its designers make a particular point of delivering the latest security patches and fixes to its users. For more about its security features see CBL-Mariner's GitHub security features list. Like any other Linux distro, CBL-Mariner is built on the shoulders of giants. Microsoft credits VMware's Photon OS Project, a secure Linux, The Fedora Project, Linux from Scratch -- a guide to building Linux from source, the OpenMamba distro, and, yes, even GNU and the Free Software Foundation (FSF). To try it for yourself, you'll build it on Ubuntu 18.04. Frankly, I'd be surprised if you couldn't build it on any Ubuntu Linux distro from 18.04 on up. I did it on my Ubuntu 20.04.2 desktop. You'll also need the latest version of the Go language and Docker.

An anonymous reader shares a report: Blender is one of the most important open source projects, as the 3D graphics application suite is used by countless people at home, for business, and in education. The software can be used on many platforms, such as Windows, Mac, and of course, Linux. Today, Ubuntu-maker Canonical announces it will offer paid enterprise support for Blender LTS. Surprisingly, this support will not only be for Ubuntu users. Heck, it isn't even limited to Linux installations. Actually, Canonical will offer this support to Blender LTS users on Windows, Mac, and Linux.

"Everything from Visual Studio Code to Microsoft Edge and Teams package links were affected," reports Windows Central. They note Azure's status page (which now shows the issue lasting for more than 22 hours), though however long it lasted, "it's a virtual eternity for those whose entire ecosystem is crippled by such an outage."

According to Ars Technica, starting on Wednesday, "packages.microsoft.com — the repository from which Microsoft serves software installers for Linux distributions including CentOS, Debian, Fedora, OpenSUSE, and more — went down hard..." The outage impacted users trying to install .NET Core, Microsoft Teams, Microsoft SQL Server for Linux (yes, that's a thing) and more — as well as Azure's own devops pipelines.

We first became aware of the problem Wednesday evening when we saw 404 errors in the output of apt update on an Ubuntu workstation with Microsoft Teams installed. The outage is somewhat better-documented at this .NET Core issue report on Github, with many users from all around the world sharing their experiences and theories...

The entire repository cluster that serves all Linux packages for Microsoft was completely down — issuing a range of HTTP 404 (content not found) and 500 (Internal Server Error) messages for any URL — for roughly 18 hours. Microsoft engineer Rahul Bhandari confirmed the outage roughly five hours after it was initially reported, with a cryptic comment about the infrastructure team "running into some space issues."

Eighteen hours after the issue was detailed, Bhandari said that the mirrors were once again available — although with temporarily degraded performance, likely due to cold caches.

Long-time Slashdot reader wildstoo writes: In a blog post on Thursday, GitHub security researcher Kevin Backhouse announced that Polkit, a Linux system service included in several modern Linux distros that provides an organized way for non-privileged processes to communicate with privileged ones, has been harbouring a major security bug for seven years.

The bug, assigned (CVE-2021-3560) allows a non-privileged user to gain administrative shell access with a handful of standard command line tools. The bug was fixed on June 3, 2021 in a coordinated disclosure.
"It's used by systemd," GitHub's blog post points out, "so any Linux distribution that uses systemd also uses polkit..."

"It's very simple and quick to exploit, so it's important that you update your Linux installations as soon as possible. Any system that has polkit version 0.113 (or later) installed is vulnerable. That includes popular distributions such as RHEL 8 and Ubuntu 20.04."

Slashdot reader AleRunner writes: Ubuntu has announced that, with immediate effect Ubuntu's IRC channels are moving to libera.chat. The move follows a "hostile takeover" of Ubuntu's namespace by Freenode's new management that appears to be happening to many other distributions including Gentoo as well as other projects that have used Freenode [including channels associated with the programming languages Raku, Elixir, and Haskell].

For Ubuntu, and many other FOSS projects, Freenode has long been one of the major official forms of communication... With IRC channels often used for important system advice, and project communication, this becomes not just an inconvenience but even a security problem. For this reason Ubuntu's replacement network, libera.chat has a more clearly open organisational structure than Freenode had before being taken over.
"All told, it appears something like 700 irc.freenode.net channels have been seized and re-permissioned," reports The Register, "supposedly because the channels mentioned Libera Chat in violation of Freenode's advertising policy."

Wednesday Freenode owner Andrew Lee posted a blog post explaining that "in retrospect, we should have handled the action of closing down channels slightly differently..."

"The intent of doing this was not an attempt of a hostile takeover nor hijack like many people are saying. Since certain projects were disrupting their users' ability to chat on freenode via mass kicks, force closures, spam, we decided to enact this policy in those places which were deemed in violation and could cause an issue later...

"We believe we should have done this in a much more communicative way to circulate the right message and keep things transparent which of course did not happen. As we move forward I'd like to fully assure you that we will be working in complete commitment to restore projects, namespaces and channels that were closed on accident as a part of this event and we welcome them to use freenode as before as their very own homebase.

"Lastly, there are no excuses for this, and I'm willing to admit that I was wrong with Tuesday's move and apologize for the inconvenience that may have caused."

An anonymous reader quotes a report from TorrentFreak: Every day, people who download and share pirated content receive DMCA notices via their ISPs, warning them to cease and desist their infringing behavior. While the majority of these notices are accurate, one Ubuntu user says he has just been targeted by an anti-piracy company alleging that by torrenting an OS ISO released by Ubuntu itself, he breached copyright law. Posting to Reddit's /r/linux sub-Reddit, a forum with more than 656K subscribers, 'NateNate60' reported the unthinkable. After downloading an official Ubuntu ISO package (filename ubuntu-20.04.2.0-desktop-amd64.iso) he says he received a notice from Comcast's Infinity claiming that he'd been reported for copyright infringement.

"We have received a notification by a copyright owner, or its authorized agent, reporting an alleged infringement of one or more copyrighted works made on or over your Xfinity Internet service," the posted notice reads. NateNate60 wisely redacted the notice to remove the 'Incident Number' and the precise time of the alleged infringement to protect his privacy but the clam was reported filed with Comcast on May 24, 2021. "The copyright owner has identified the IP address associated with your Xfinity Internet account at the time as the source of the infringing works," it continues, adding that NateNate60 should search all of his devices connected to his network and delete the files mentioned in the complaint.

The allegedly infringing content is the 64-bit Ubuntu 20.04.2.0 LTS release but the first big question is whether the file is actually the official release from Canonical. Given that the listed hash value is 4ba4fbf7231a3a660e86892707d25c135533a16a and that matches the hash of the official release, mislabeled or misidentified content (wrong hash, mislabeled file etc) appears to be ruled out. Indeed, the same hash value is listed on Ubuntu's very own BitTorrent tracker and according to NateNate60, this is where he downloaded the torrent that led to the DMCA notice. It doesn't get much more official than that. According to the DMCA notice sent by Comcast, the complainant wasn't Ubuntu/Canonical but an anti-piracy company called OpSec Security, which according to its imprint is based in Germany. Presuming the notice is genuine (albeit sent in error), Comcast needs to be informed that mistakes have been made. The ISP has a repeat infringer policy and given the current hostile environment, terminating users is certainly on the agenda. Indeed, the notice states just that.

This week ZDNet dedicated an article to "the most popular Fedora Linux in years." Red Hat's community Linux distribution Fedora has always been popular with open-source and Linux developers, but this latest release, Fedora 34 seems to be something special. As Matthew Miller, Fedora Project Leader, tweeted, "The beta for F34 was one of the most popular ever, with twice as many systems showing up in my stats as typical."

Why? Nick Gerace, a Rancher software engineer, thinks it's because "I've never seen the project in a better state, and I think GNOME 40 is a large motivator as well. Probably a combination of each, from anecdotal evidence." He's onto something. When Canonical released Ubuntu 21.04 a few days earlier, their developers opted to stay with the tried and true GNOME 39 desktop. Fedora's people decided to go with GNOME 40 for their default desktop even though it's a radical update to the GNOME interface. Besides boasting a new look, GNOME 40 is based on the new GTK 4.0 graphical toolkit. Under the pretty new exterior, this update also fixed numerous issues and smoothed out many rough spots.

If you'd rather have another desktop, you can also get Fedora 34 with the newest KDE Plasma Desktop, Xfce 4.16, Cinnamon, etc. You name your favorite Linux desktop interface, Fedora will almost certainly deliver it to you... Another feature I like is that, since Fedora 33, the default file system is Btrfs. I find it faster and more responsive than ext4, perhaps the most popular Linux desktop file system. What's different this time around is that it now defaults to using Btrfs transparent compression. Besides saving significant storage space — typically from 20 to 40% — Red Hat also claims this increases the lifespan of SSDs and other flash media.
Although the article does point out that most users will never reach the end of that SSD lifespan (approximately ten years of normal use), it suggests that "developers, who might for example compile Linux kernels every day, might reach that point before a PC's usual end of useful life."

In a possibly related note, Linus Torvalds said this week in a new interview that "I use Fedora on all my machines, not because it's necessarily 'preferred', but because it's what I'm used to. I don't care deeply about the distribution — to me it's mainly a way to get Linux installed on a machine and get all my tools set up, so that I can then replace the kernel and work on just that."

destinyland writes: LWN has a terrific update what's happened since the discovery of University of Minnesota researchers intentionally submitting buggy code to the Linux kernel:

The writing of a paper on this research [PDF] was not the immediate cause of the recent events; instead, it was the posting of a buggy patch originating from an experimental static-analysis tool run by another developer at UMN. That led developers in the kernel community to suspect that the effort to submit intentionally malicious patches was still ongoing. Since then, it has become apparent that this is not the case, but by the time the full story became clear, the discussion was already running at full speed.

The old saying still holds true: one should not attribute to malice that which can be adequately explained by incompetence.

On April 22, a brief statement was issued by the Linux Foundation technical advisory board (TAB) stating that, among other things, the recent patches appeared to have been submitted in good faith.

Meanwhile, the Linux Foundation and the TAB sent a letter to the UMN researchers outlining how the situation should be addressed; that letter has not been publicly posted, but ZDNet apparently got a copy from somewhere. Among other things, the letter asked for a complete disclosure of the buggy patches sent as part of the UMN project and the withdrawal of the paper resulting from this work.

In response, the UMN researchers posted an open letter apologizing to the community, followed a few days later by a summary of the work they did [PDF] as part of the "hypocrite commits" project. Five patches were submitted overall from two sock-puppet accounts, but one of those was an ordinary bug fix that was sent from the wrong account by mistake. Of the remaining four, one of them was an attempt to insert a bug that was, itself, buggy, so the patch was actually valid; the other three (1, 2, 3) contained real bugs. None of those three were accepted by maintainers, though the reasons for rejection were not always the bugs in question.

The paper itself has been withdrawn and will not be presented in May as was planned...

One of the first things that happened when this whole affair exploded was the posting by Greg Kroah-Hartman of a 190-part patch series reverting as many patches from UMN as he could find... As it happens, these "easy reverts" also needed manual review; once the initial anger passed there was little desire to revert patches that were not actually buggy. That review process has been ongoing over the course of the last week and has involved the efforts of a number of developers. Most of the suspect patches have turned out to be acceptable, if not great, and have been removed from the revert list; if your editor's count is correct, 42 patches are still set to be pulled out of the kernel...

A look at the full set of UMN patches reinforces some early impressions, though. First is that almost all of them do address some sort of real (if obscure and hard to hit) problem...

Canonical released Ubuntu 21.04 with native Microsoft Active Directory integration, Wayland graphics by default, and a Flutter application development SDK. Separately, Canonical and Microsoft have announced performance optimization and joint support for Microsoft SQL Server on Ubuntu. Canonical blog adds: "Native Active Directory integration and certified Microsoft SQL Server on Ubuntu are top priorities for our enterprise customers." said Mark Shuttleworth, CEO of Canonical. "For developers and innovators, Ubuntu 21.04 delivers Wayland and Flutter for smoother graphics and clean, beautiful, design-led cross-platform development." You can read the full list of new features and changelog here.

Long-time Slashdot reader xiando quotes LinuxReviews: The community distribution Arch Linux has up to now required you to manually install it by entering a whole lot of scary commands in a terminal. Arch version 2021.04.01 features a new guided installer [reached by] typing python -m archinstall guided into the console you get when you boot the Arch Linux installation ISO.

It is not very novice-friendly, or user-friendly, but it gets the job done and it will work fine for those with some basic GNU/Linux knowledge.
Tech Radar writes that previously Arch Linux had "a rather convoluted installation process, which has given rise to a stream of Arch-based distros that are easier to install," adding that the new installer "was reportedly promoted as an official installation mechanism back in January, and was actively worked upon leading to its inclusion in the installation medium." Users have been calling on Arch Linux for simplifying the installation process for a long time, to bring it in line with other Linux distros. However, the Arch philosophy has always been to put the users in charge of every aspect of their installation, which is the antithesis of automated installers.
Phoronix calls the new installer "very quick and easy," although "granted not as user-friendly / polished as say the Debian Installer, Red Hat's Anaconda installer, even Ubuntu's Subiquity, and other TUI/GUI Linux installers out there." They also note that Archinstall "does allow automatically partitioning the drive with your choice of file-system options, automatically installing a desktop environment if desired, configuring the network interfaces, and all the other basics." The method is quick enough that I'll likely use archinstall for future Arch Linux benchmarks on Phoronix as it also then applies a sane set of defaults for users... Five minutes or less and off to the races, ready for Arch Linux."
But Slashdot reader I75BJC still favors "scary commands in a terminal," leaving this comment on the original submission: If you can't type with the big adults, stay on your PlayStation.

Even Apple, with its very good GUI has a command line. The command line commands are more flexible, more specific, more subtle than the pointy-clicky GUI.

IBM has announced a COBOL compiler for Linux on x86. "IBM COBOL for Linux on x86 1.1 brings IBM's COBOL compilation technologies and capabilities to the Linux on x86 environment," said IBM in an announcement, describing it as "the latest addition to the IBM COBOL compiler family, which includes Enterprise COBOL for z/OS and COBOL for AIX." The Register reports: COBOL -- the common business-oriented language -- has its roots in the 1950s and is synonymous with the mainframe age and difficulties paying down technical debt accrued since a bygone era of computing. So why is IBM -- which is today obsessed with hybrid clouds -- bothering to offer a COBOL compiler for Linux on x86? Because IBM thinks you may want your COBOL apps in a hybrid cloud, albeit the kind of hybrid IBM fancies, which can mean a mix of z/OS, AIX, mainframes, POWER systems and actual public clouds.
[...]
But the announcement also suggests IBM doesn't completely believe this COBOL on x86 Linux caper has a future as it concludes: "This solution also provides organizations with the flexibility to move workloads back to IBM Z should performance and throughput requirements increase, or to share business logic and data with CICS Transaction Server for z/OS." The new offering requires RHEL 7.8 or later, or Ubuntu Server 16.04 LTS, 18.04 LTS, or later.
