"The new Fieldbus system has been deemed ready to be released into the staging area of the Linux kernel," writes jwhyche (Slashdot reader #6,192).

Phoronix reports: This newest subsystem for the Linux kernel benefits industrial systems. Fieldbus is a set of network protocols for real-time distributed control of automated industrial systems. Fieldbus is used for connecting different systems/components/instruments within industrial environments. Fieldbus is used for connecting facilities ranging from manufacturing plants up to nuclear energy facilities. The Fieldbus specification has been around for decades while now seeing a formal subsystem within the Linux kernel.

The subsystem allows for devices to exchange data over a Fieldbus whether it be Profinet, FLNet, or one of the other implementations. The subsystem provides a generic framework for exposing switches, lights, actuators, motors, and other hardware... The Linux kernel's Fieldbus subsystem has gone through over ten rounds of public revisions in recent months and has been deemed ready to premiere with Linux 5.2 [which] should debut in July.

Canonical today announced the release of Ubuntu 19.04 "Disco Dingo." With Linux 5.0 and GNOME 3.32, Disco Dingo features performance improvements and visual tweaks. Whether or not you upgrade, Disco Dingo lays the groundwork for future long term support releases of Ubuntu. From a report: Keep in mind, version 19.04 is not LTS (Long Term Support), meaning it is only supported until January 2020. "Ubuntu 19.04 introduces GNOME 3.32 with higher frame rates, smoother startup animations, quicker icon load times and reduced CPU+GPU load. Fractional scaling for HiDPI screens is now available in X-org and Wayland. Installing Ubuntu on VMWare will automatically install open-vm-tools for bi-directional clipboard, easy sharing of files and graceful power state management," says Canonical. The Ubuntu-maker further says, "In Ubuntu 19.04, multiple instances of the same snap can be installed for CI/CD, testing or phased rollouts. For example, two versions of a database or two versions of the golang compiler can be installed at the same time. Snap epochs control when and how data migration happens between major version upgrades."

"I believe that, as Microsoft keeps moving Windows to a Desktop-as-a-Service model, Linux will be the last traditional PC desktop operating system standing," writes ZDNet contributing editor Steven J. Vaughan-Nichols.

"But that doesn't mean I'm blind to its problems." First, even Linus Torvalds is tired of the fragmentation in the Linux desktop. In a recent [December 2018] TFiR interview with Swapnil Bhartiya, Torvalds said, "Chromebooks and Android are the path toward the desktop." Why? Because we don't have a standardized Linux desktop. For example, better Linux desktops, such as Linux Mint, provide an easy way to install applications, but under the surface, there are half-a-dozen different ways to install programs. That makes life harder for developers. Torvalds wishes "we were better at having a standardized desktop that goes across the distributions."

Torvalds thinks there's been some progress. For software installation, he likes Flatpak. This software program, like its rival Snap, lets you install and maintain programs across different Linux distros. At the same time, this rivalry between Red Hat (which supports Flatpak) and Canonical (which backs Snap) bugs Torvalds. He's annoyed at how the "fragmentation of the different vendors have held the desktop back." None of the major Linux distributors -- Canonical, Red Hat, SUSE -- are really all that interested in supporting the Linux desktop. They all have them, but they're focused on servers, containers, the cloud, and the Internet of Things (IoT). That's, after all, is where the money is.
Linux desktop distros "tend to last for five or six years and then real life gets in the way of what's almost always a volunteer effort..." the article argues. "It is not easy building and supporting a Linux desktop. It comes with a lot of wear and tear on its developers with far too little reward."

His solution? Having a foundation create a common desktop for all Linux distros, so the Linux world could finally reap the benefits of standardization. "This would mean that many more Linux desktop developers could make a living from their work. That would improve the Linux desktop overall quality.

"It's a virtuous cycle, which would help everyone."

This weekend SlashGear published "Reasons to Abandon Windows For Linux," making their case to "Windows users who are curious about the state of Linux for mainstream computing." It tries to enumerate specific reasons why Linux might be the better choice, arguing among other things that:

• Updates on Linux are fast and "rarely call for a restart" -- and are also more complete. "Updates are typically downloaded through a 'Software Updater' application that not only checks for operating system patches, but also includes updates for the programs that you've installed from the repository."

• Windows "tries to serve a variety of markets...cramming in a scattered array of features" -- and along those lines, that Microsoft "has gradually implemented monetization schemes and methods for extracting user data." And yet you're still paying for that operating system, while Linux is less bloated and "free forever."

• "Because less people use Linux, the platform is less targeted by malware and tends to be more secure than Windows"

The article also touches on a few other points (including battery life), and predicts that problems with Windows are "bound to get worse over time and will only present more of a case for making the switch to Linux."

Long-time Slashdot reader shanen shared the article, along with some new thoughts on why people really stay with Windows:

I think the main "excuse" is the perception of reliability, which is really laughable if you've actually read the EULA. Microsoft certainly doesn't have to help anyone at all. I would argue that Windows support is neither a bug nor a feature, but just a marketing ploy.

Their original submission suggests that maybe Linux needs to buttress the perception of its reliability with a better financial model -- possibly through a new kind of crowd funding which could also be extended to all open source software, or even to journalism).

Following the release of Visual Studio 2019 for Windows and Mac platforms, Microsoft today is releasing a snap version of Visual Studio Code. A report adds: No, the source-code editor is not the Windows-maker's first snap -- it also released one for Skype, for instance. "As of today, Visual Studio Code is available for Linux as a snap, providing seamless auto-updates for its users. Visual Studio Code, a free, lightweight code editor, has redefined editors for building modern web and cloud applications, with built-in support for debugging, task running, and version control for a variety of languages and frameworks," says Canonical. Joao Moreno, Software Development Engineer, Microsoft Visual Studio Code offers the following statement: "The automatic update functionality of snaps is a major benefit. It is clear there is a thriving community around snaps and that it is moving forward at great pace. The backing of Canonical ensures our confidence in its ongoing development and long-term future."

mfilion shares a report from Android Police: A new "experimental containerized Android environment" from a company called Collabora allows Android apps to run in floating windows alongside native applications on desktop Linux. You can read all the technical details at the source link, but put simply, 'SPURV' creates a virtual Android device on your Linux computer, much like Bluestacks and other similar tools. There are various components of SPURV that allow the Android environment to play audio, connect to networks, and display hardware-accelerated graphics through the underlying Linux system.

The most interesting part is 'SPURV HWComposer,' which renders Android applications in windows, alongside the windows from native Linux applications. This is what sets SPURV apart from (most) other methods of running Android on a computer. For this to work, the Linux desktop has to be using the Wayland display server (some Linux-based OSes use X11). Pre-built binaries for SPURV are not currently available -- you have to build it yourself from the source code. Still, it's an interesting proof-of-concept, and hopefully someone turns it into a full-featured product.

From a wide-ranging interview of Linus Torvalds with Linux Journal on the magazine's 25th anniversary: Linux Journal: If you had to fix one thing about the networked world, what would it be?
Linus: Nothing technical. But, I absolutely detest modern "social media" -- Twitter, Facebook, Instagram. It's a disease. It seems to encourage bad behavior. I think part of it is something that email shares too, and that I've said before: "On the internet, nobody can hear you being subtle". When you're not talking to somebody face to face, and you miss all the normal social cues, it's easy to miss humor and sarcasm, but it's also very easy to overlook the reaction of the recipient, so you get things like flame wars, etc., that might not happen as easily with face-to-face interaction. But email still works. You still have to put in the effort to write it, and there's generally some actual content (technical or otherwise). The whole "liking" and "sharing" model is just garbage. There is no effort and no quality control. In fact, it's all geared to the reverse of quality control, with lowest common denominator targets, and click-bait, and things designed to generate an emotional response, often one of moral outrage.

Add in anonymity, and it's just disgusting. When you don't even put your real name on your garbage (or the garbage you share or like), it really doesn't help. I'm actually one of those people who thinks that anonymity is overrated. Some people confuse privacy and anonymity and think they go hand in hand, and that protecting privacy means that you need to protect anonymity. I think that's wrong. Anonymity is important if you're a whistle-blower, but if you cannot prove your identity, your crazy rant on some social-media platform shouldn't be visible, and you shouldn't be able to share it or like it.

Linux Journal: Is there any advice you'd like to give to young programmers/computer science students?
Linus: I'm actually the worst person to ask. I knew I was interested in math and computers since an early age, and I was largely self-taught until university. And everything I did was fairly self-driven. So I don't understand the problems people face when they say "what should I do?" It's not where I came from at all.

Brian Fagioli, reporting for BetaNews: Today should be happy times for the Linux Mint community, as we finally learn some new details about the upcoming version 19.2! It will be based on Ubuntu 18.04 and once again feature three desktop environments -- Xfce, Mate, and Cinnamon. We even found out the code name for Linux Mint 19.2 -- "Tina." And yet, it is hard to celebrate. Why? Because the developers seem to be depressed and defeated. They even appear to be a bit disenchanted with Free Software development overall. Clement Lefebvre, leader of the Linux Mint project, shared a very lengthy blog post today, and it really made me sad.

He wrote, "For a team to work, developers need to feel like heroes. They want the same things as users, they are users, they were 'only' users to start with. At some stage they decide to get involved and they start investing time, efforts and emotions into improving our project. What they're looking for the most is support and happiness. They need feedback and information to understand bugs or feature requests and when they're done implementing something, they need to feel like heroes, they literally do, that's part of the reason they're here really." Upon publication of the article, Jason Hicks, Muffin maintainer and member of the Linux Mint team, corroborated the claims made by others.

At SUSECon in Nashville, Tennessee, European Linux power SUSE CEO Nils Brauckmann said his company would soon be the largest independent Linux company. "That's because, of course, IBM is acquiring Red Hat," reports ZDNet. "But, simultaneously, SUSE has continued to grow for seven-straight years." From the report: Brauckmann said, "We believe that makes our status as a truly independent open source company more important than ever. Our genuinely open-source solutions, flexible business practices, lack of enforced vendor lock-in, and exceptional service are more critical to customer and partner organizations, and our independence coincides with our single-minded focus on delivering what is best for them." Practically speaking, SUSE has been growing by focusing on delivering high-quality Linux and open-source programs and services to enterprise customers. Looking ahead Brauckmann said, "SUSE is better positioned to bring more innovation to customers and partners faster through both organic growth and acquisitions, keeping us on track to provide them with the open solutions that keep them ahead with their own customers in their own markets. We continue to adapt so our customers and partners can succeed."

Last year SUSE's revenue grew by 15 percent in fiscal year 2018, and the business is about to surpass the $400 million revenue mark for the first time. SUSE, which sees not quite half of its business in Europe, is also seeing revenue growth around the world. North America, for example, now accounts for almost 40 percent of SUSE's revenues. The company is also expanding. SUSE added more than 300 employees in the last 12 months. For the most part this has been in engineering followed by sales and services. SUSE staff is now approaching 1,750 globally and its plans on continuing to hire aggressively.

An anonymous reader shares a report: Today, Canonical's Ubuntu reaches a major milestone. You see, Ubuntu 19.04, which is named "Disco Dingo," has achieved Beta status. And yes, you can download it immediately. Fans of GNOME will be glad to know that version 3.32 is included in the standard Ubuntu Desktop release. Also cool? This is the first version of Ubuntu to use Linux kernel 5.

Five candidates now are running to be Debian's project leader for the coming year. But earlier this week, Slashdot reader Seven Spirals shared LWN's story about what a difficult election it's been: This year, the call for nominations was duly sent out by project secretary Kurt Roeckx on March 3. But, as of March 10, no eligible candidates had put their names forward... There is nobody there to do any campaigning.

This being Debian, the constitution naturally describes what is to happen in this situation: the nomination period is extended for another week... Should this deadline also pass without candidates, it will be extended for another week; this loop will repeat indefinitely until somebody gives in and submits their name... In the absence of a project leader, the chair of the technical committee and the project secretary are empowered to make decisions -- as long as they are able to agree on what those decisions should be. Since Debian developers are famously an agreeable and non-argumentative bunch, there should be no problem with that aspect of things...

One might well wonder, though, why there seems to be nobody who wants to take the helm of this project for a year. The fact that it is an unpaid position requiring a lot of time and travel might have something to do with it. If that were indeed to prove to be part of the problem, Debian might eventually have to consider doing what a number of similar organizations have done and create a paid position to do this work.

An anonymous reader quotes a report from VentureBeat: Google today launched Chrome 73 for Windows, Mac, and Linux. The release includes support for hardware media keys, PWAs and dark mode on Mac, and the usual slew of developer features. You can update to the latest version now using Chrome's built-in updater or download it directly from google.com/chrome. Chrome 73 supports Progressive Web Apps (PWAs) on macOS. These apps install and behave like native apps (they don't show the address bar or tabs). Google killed off Chrome apps last year and has been focusing on PWAs ever since. Adding Mac support means Chrome now supports PWAs on all desktop and mobile platforms: Windows, Mac, Linux, Chrome OS, Android, and iOS. Chrome now also supports dark mode on Apple's macOS; dark mode for Windows is on the way, the team promises.

The VentureBeat report includes a long list of developer features included in this release, as well as all the security fixes found by external researchers. Chrome 73 implements a total of 60 security fixes.

The Linux Foundation today unveiled several major collaborative partnerships as it looks to cement the development of various open source projects that power much of the web. From a report: First off, the Node.js Foundation and the JS Foundation, which the Linux Foundation launched in 2016, are merging to form the OpenJS Foundation. The merger between the two chief organizations that focus on JavaScript comes six months after they publicly began to explore such a possibility with their communities. The OpenJS Foundation will focus on hosting and funding activities that support the growth of JavaScript and web technologies, the Linux Foundation said in a press release.

The OpenJS Foundation consists of 29 open source JavaScript projects including jQuery, Node.js, Appium, Dojo, and webpack. The merger is supported by 30 corporate and end user members including Google, Microsoft, IBM, PayPal, GoDaddy, and Joyent that recognize the "interconnected nature of the JavaScript ecosystem, and the importance of providing a neutral home for projects which represent significant shared value," the Linux Foundation said in a prepared statement. Also in the report: The Linux Foundation has created CHIPS Alliance, a project that aims to host and curate open source code relevant to design of chips that power mobile, IoT, and other consumer electronic devices; and the Continuous Delivery Foundation, which aims to serve as a platform for vendors, developers, and users to frequently engage and share insights and best practices to spur the development of open source projects.

It also announced that the GraphQL Foundation is collaborating with Joint Development Foundation to encourage "contributions, stewardship, and a shared investment from a broad group in vendor-neutral events, documentation, tools, and support for the data query language."

Michael Stapelberg, maintains "a bunch" of Debian packages and services, and says the free software Linux distro "has been in my life for well over 10 years at this point."

Today he released a 2,255-word essay explaining why he's "winding down" his involvement in Debian to a minimum, citing numerous complaints including Debian's complicated build stack, waits of up to seven hours before package uploads can be installed, leading to "asynchronous" feedback -- and Debian's lack of tooling for large changes.
The closest to "sending out a change for review" is to open a bug report with an attached patch... Culturally, reviews and reactions are slow. There are no deadlines. I literally sometimes get emails notifying me that a patch I sent out a few years ago (!!) is now merged. This turns projects from a small number of weeks into many years, which is a huge demotivator for me.

Interestingly enough, you can see artifacts of the slow online activity manifest itself in the offline culture as well: I don't want to be discussing systemd's merits 10 years after I first heard about it.

Lastly, changes can easily be slowed down significantly by holdouts who refuse to collaborate. My canonical example for this is rsync, whose maintainer refused my patches to make the package use debhelper purely out of personal preference. Granting so much personal freedom to individual maintainers prevents us as a project from raising the abstraction level for building Debian packages, which in turn makes tooling harder.
There's also several complaints about old infrastructure -- for example, "I dread interacting with the Debian bug tracker. debbugs is a piece of software (from 1994) which is only used by Debian and the GNU project these days." Stapelberg also complains that the "painful" experience of developing using Debian "leaves a lot to be desired," and adds that "It baffles me that in 2019, we still don't have a conveniently browsable threaded archive of mailing list discussions."

"My frustration level ultimately exceeded the threshold," Stapelberg writes in the essay, adding "I hope this post inspires someone, ideally a group of people, to improve the developer experience within Debian." He'll soon transition packages to be team-maintained "where it makes sense," but also "orphan packages where I am the sole maintainer... For all intents and purposes, please treat me as permanently on vacation..."

"I will try to keep up best-effort maintenance of the manpages.debian.org service and the codesearch.debian.net service, but any help would be much appreciated."

"For over a decade, VMware has been accused of illegally using Linux code in its VMware ESX bare-metal virtual machine hypervisor," reports ZDNet, adding that "A German court has dismissed the case, but the struggle may not be over." VMware stood accused of illegally using Linux code in its flagship VMware ESX bare-metal virtual machine (VM) hypervisor... In 2011, the Software Freedom Conservancy, a non-profit organization that promotes open-source software, discovered that VMware had failed to properly license any Linux or BusyBox, a popular embedded Linux toolkit, source code... In 2015, having exhausted all other means, [Linux kernel developer Christoph] Hellweg and the Software Freedom Conservancy sued VMware in the district court of Hamburg in Germany. Besides the general violation of the GPLv2, "Conservancy and Hellwig specifically assert that VMware has combined copyrighted Linux code, licensed under GPLv2, with their own proprietary code called 'vmkernel' and distributed the entire combined work without providing nor offering complete, corresponding source code for that combined work under terms of the GPLv2."

The German court disagreed in November 2018. Helwig appealed and continued the fight, saying "The lower court dismissed the case as a result of evidentiary rules and likely an incomplete understanding of the documentation of the code in question...." [Monday] VMware rather mysteriously announced: "VMware is pleased with the Feb. 28, 2019 decision of the German appellate court in Hamburg to dismiss Mr. Hellwig's appeal and let stand the regional court's decision to dismiss Mr. Hellwig's lawsuit. "
Karen Sandler, attorney and the Conservancy's executive director, told ZDNet that "We strongly believe that litigation is necessary against willful GPL violators, particularly in cases like VMware where this is strong community consensus that their behavior is wrong. Litigation moves slowly. We will continue to discuss this with Christoph and his lawyers and hope to say more about it in the coming weeks -- after the courts provide their rationale for their decision to the parties (which has not yet occurred)."

Meanwhile, VMware stated that it "continues to be a strong supporter of open source software development," adding that it's been "actively" working on removing vmklinux from vSphere in an upcoming release as part of a multi-year project -- "for reasons unrelated to the litigation."

Linux 5.1 continues the massive undertaking in preparing the kernel for the Year 2038 problem. Phoronix: The Linux kernel has been seeing "Y2038" work for years and the effort is far from over. Thomas Gleixner (a Linux kernel developer who serves as a member of the technical advisory board at The Linux Foundation) sent in the latest Y2038 work for the Linux 5.1 kernel, which after a lot of ground work in previous kernels has introduced the first set of syscalls that are Year 2038 safe.

An anonymous reader writes: Linus Torvalds has released Linux 5.0 in kicking off the kernel's 28th year of development. Linux 5.0 features include AMD FreeSync support, open-source NVIDIA Turing GPU support, Intel Icelake graphics, Intel VT-d scalable mode, NXP PowerPC processors are now mitigated for Spectre Variant Two, and countless other additions. eWeek adds: Among the new features that have landed in Linux 5.0 is support for the Adiantum encryption system, developed by Google for low power devices. Google's Android mobile operating system and ChromeOS desktop operating system both rely on the Linux kernel. "Storage encryption protects your data if your phone falls into someone else's hands," Paul Crowley and Eric Biggers, Android Security and Privacy Team at Google wrote in a blog post. "Adiantum is an innovation in cryptography designed to make storage encryption more efficient for devices without cryptographic acceleration, to ensure that all devices can be encrypted. Memory management in Linux also gets a boost in the 5.0 kernel with a series of improvements designed to help prevent memory fragmentation, which can reduce performance.

For some reason, Apple's website where you can manage your Apple ID (appleid.apple.com) is blocking users of Linux browsers from accessing it. From a report: Having access to the website is important to manage things such as payment information, two-factor authentication, and other account details. Even though the number of Linux users accessing the website must be relatively small compared to other operating systems, some iPhone users who use Linux on the desktop noticed the issue. This behavior was first explained by user Alexander Martin on Mastodon. He discovered that when the browser reports itself as being a Linux browser, Apple's website will block the access by throwing a "Bad Gateway" error.

The Linux Foundation today launched Enabling Linux in Safety Applications (ELISA), an open source project comprising tools intended to help companies build and certify Linux-based systems whose failure could result in loss of human life, significant property damage, or environmental damage. From a report: In partnership with British chip designer Arm, BMW, autonomous platforms company Kuka, Linutronix, and Toyota, ELISA will work with certification and standardization bodies in "multiple industries" to establish ways Linux can form the foundation of safety-critical systems across industries.

dryriver writes: A lot of people probably remember the 1990s palmtop computers made by Psion fondly. The clamshell-design palmtops were pocketable, black and white, but had a working stylus and a fantastic tactile foldout QWERTY keyboard that you could type pretty substantial documents on or even write code with. A different company -- Planet Computers -- has now produced a spiritual successor to the old Psion palmtops called the Gemini PDA that is much like an old Psion but with the latest Android smartphone hardware in it and a virtually identical tactile keyboard. It can also dual boot to Linux (Debian, Ubuntu, Sailfish) alongside Android. The technical specs are a MediaTek deca-core processor, 4GB RAM, 64GB storage (plus microSD slot), 4G, 802.11c Wi-Fi, GPS, Bluetooth, eSIM support, and 4,220mAh battery. The screen measures in at 5.99-inches with a 2,160 x 1,080 (403ppi) resolution. The only thing missing seems to be the stylus -- but perhaps that would have complicated manufacturing of this niche-device in its first production run.
