An anonymous reader shares a report: Elastic isn't the only open source cloud tool company currently looking over its shoulder at AWS. In 2018 alone, at least eight firms have made similar "rule changes" designed to ward off what they see as unfair competition from a company intent on cannibalizing their services. In his blog post, Adrian Cockcroft, VP of cloud architecture strategy at Amazon Web Services (AWS), argued that by making part of its product suite proprietary, Elastic was betraying the core principles of the open source community. "Customers must be able to trust that open source projects stay open," Cockcroft wrote. "When important open source projects that AWS and our customers depend on begin restricting access, changing licensing terms, or intermingling open source and proprietary software, we will invest to sustain the open source project and community."

AWS's announcement did not attract the immediate attention of the Democratic presidential candidates or the growing cadre of antitrust activists who have recently set their sights on Amazon. But in the world of open source and free software, where picayune changes in arcane language can spark the internet equivalent of the Hundred Years War, the release of AWS's Open Distro for Elasticsearch launched a heated debate. [...] Sharone Zitzman, a respected commentator on open source software and the head of developer relations at AppsFlyer, an app development company, called Amazon's move a "hostile takeover" of Elastic's business. Steven O'Grady, co-founder of the software industry analyst firm RedMonk, cited it as an example of the "existential threat" that open source companies like Elastic believe a handful of cloud computing giants could pose.

"Big changes are here," writes the official blog for Bluecherry: In 2010 we released our multi-port MPEG4 video capture card with an open source driver (solo6x10) and in 2011 updated the driver to support our multi-port H.264 capture cards. Later, this open source driver was later added into the mainline Linux kernel. In 2013 we released our multi-platform surveillance application client with an open source (GPL) license.

We are proud to announce that Effective April 18, 2019 we have released the entire Bluecherry software application open source with a GPL license.

"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.

"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."

arnieswap quotes TFIR's report on the black hole image: Free and Open Source software was at the heart of this image. The team used three different imaging software libraries to achieve the feat. Out of the three, two were fully open source libraries. The source code of the software is publicly available on GitHub.

Richard M Stallman, the founder of the GNU Project will be glad to see that both libraries (Sparselab and ehtim) are released under GNU GPL v3. Yes, you read it right – GNU GPL v3.

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).

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.

According to the Wall Street Journal, Goldman Sachs is planning to release on GitHub some of the code that its traders and engineers use to price securities and analyze and manage risk. "The bank also is offering $100,000 in annual funding for engineers to build new applications using the bank's code," the report adds. "Goldman will own the resulting intellectual property, plus get an early look to invest in promising technology." From the report: It is Goldman's latest move to shed some of its trademark secrecy and share its once closely guarded technology. It is part of a broader shift at Wall Street firms to emulate Silicon Valley giants like Google and Facebook, which have opened up their technology to a community of enthusiastic developers. By letting outsiders tinker with its code, Goldman hopes to crowdsource new uses for it and earn the loyalty of computer-driven "quant" traders who have taken the investing world by storm.

Goldman's proprietary trading engine, known as SecDB, once made its traders the smartest on Wall Street. It is credited with helping the firm weather the 2008 financial meltdown better than rivals. But a postcrisis ban on proprietary trading has made it more valuable as a service offered to clients than an in-house moneymaker. Over the past five years, Goldman has been building SecDB's capabilities into a web application called Marquee, which now has about 13,000 users roughly split between Goldman employees and clients. The code coming to GitHub will allow users to interact directly with Marquee's data feeds, pricing engines and other tools.

Wednesday CMU announced the open sourcing of its adaptive-learning software platform -- plus analytics and dozens of other related tools for improving college teaching -- as part of a national push "in an unusual move intended to shake up how college teaching is done around the world," writes EdSurge.

Long-time Slashdot reader jyosim shares their report: Officials estimate that developing the software has cost more than $100 million in foundation grants and university dollars. The goal of the software giveaway is to jump-start "learning engineering," the practice of applying findings from learning science to college classrooms. If it takes off, the effort could result in a free, open-source alternative to a growing number of commercial adaptive-learning and learning analytics tools aimed at colleges. One of the biggest concerns by college leaders about buying such tools from commercial vendors is whether colleges will have access to the underlying algorithmic logic -- or whether the systems will be a "black box...."

"We need a scientific revolution in education akin to the one that we had in medicine 150 years ago," said Michael Feldstein, coordinator of the Empirical Educator Project, in a statement. "This isn't a silver bullet, and it isn't charity. It's an invitation to the educators of the world for us all to solve big problems together."
CMU's Nobel prize-winning economics professor Herbert Simon once argued of colleges that "we must step back and view them with Martian eyes, innocent of their history, to appreciate fully how outrageous their operation is... [W]e find no one with a professional knowledge of the laws of learning, or of the techniques of applying them."

Kenneth R. Koedinger, a professor of human computer interaction and psychology at Carnegie Mellon, now argues that "we need to change higher ed from a solo sport to a collaborative research activity."

prpplague writes: Despite Linus Torvald's recent claims ARM won't win in the server space, there are very specific use cases where ARM is making advances into the datacenter. One of those is for use with software-defined storage with open-source projects like CEPH. In a recent The Register article, Softiron's CTO Phil Straw states about their ARM-based CEPH appliances: "It's a totally shitty computer, but what we are trying to do here is storage, and not compute, so when you look at the IO, when you look at the buffering, when you look at the data paths, there's amazing performance -- we can approach something like a quarter of a petabyte, at 200Gbps wireline throughput." Straw claimed that, on average, SoftIron servers run 25C cooler than a comparable system powered by Xeons." So... ARM in the datacenter might be saying, "I'm not quite dead yet!"

After being delayed for the better part of one month, LLVM 8.0 officially is finally available. From a report: LLVM release manager Hans Wennborg announced the release a few minutes ago and summed up this half-year update to LLVM and its sub-project as: "speculative load hardening, concurrent compilation in the ORC JIT API, no longer experimental WebAssembly target, a Clang option to initialize automatic variables, improved pre-compiled header support in clang-cl, the /Zc:dllexportInlines- flag, RISC-V support in lld. And as usual, many bug fixes, optimization and diagnostics improvements, etc."

Stephen O'Grady, co-founder of the industry analyst firm RedMonk, asks whether open source vendors are marching towards an inevitable and damaging war with big cloud providers: In the last twelve to eighteen months...a switch has been flipped. Companies have gone from regarding cloud providers like Amazon, Google or Microsoft as not even worth mentioning as competition to dreadful, existential threat. The fear of these cloud providers has become so overpowering, in fact, that commercial open source vendors have chosen -- against counsel, in many cases -- to walk down strategic paths that violate open source cultural norms, trigger massive and sustained negative PR and jeopardize relationships with developers, partners and customers. Specifically, commercial open source providers have increasingly turned to models that blur the lines between open source and proprietary software in an attempt to access the strengths of both, with the higher probability outcome of ending up with their weaknesses instead.

That commercial open source providers took these actions having been advised of these and other risks in advance says everything about how these businesses view their prospects in a world increasingly dominated by massive providers of cloud infrastructure and an expanding array of services that sit on top of that. The strategic decisions inarguably have major, unavoidable negative consequences, but commercial open source providers -- or their investors, at least -- believe that a lack of action would be even more damaging.

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.

Long-time Slashdot reader jasenj1 and Striek both shared news of a growing open source controversy. "Amazon Web Services on Monday announced that it's partnering with Netflix and Expedia to champion a new Open Distro for Elasticsearch due to concerns of proprietary code being mixed into the open source Elasticsearch project," reports Datanami.

"Elastic, the company behind Elasticsearch, responded by accusing Amazon of copying code, inserting bugs into the community code, and engaging with the company under false pretenses..." In a blog post, Adrian Cockcroft, the vice president of cloud architecture strategy for AWS, says the new project is a "value added" distribution that's 100% open source, and that developers working on it will contribute any improvements or fixes back to the upstream Elasticsearch project. "The new advanced features of Open Distro for Elasticsearch are all Apache 2.0 licensed," Cockroft writes. "With the first release, our goal is to address many critical features missing from open source Elasticsearch, such as security, event monitoring and alerting, and SQL support...." Cockroft says there's no clear documentation in the Elasticsearch release notes over what's open source and what's proprietary. "Enterprise developers may inadvertently apply a fix or enhancement to the proprietary source code," he wrote. "This is hard to track and govern, could lead to breach of license, and could lead to immediate termination of rights (for both proprietary free and paid)."

Elastic CEO Shay Banon responded Tuesday to AWS in a blog post, in which he leveled a variety of accusations at the cloud giant. "Our products were forked, redistributed and rebundled so many times I lost count," Banon wrote. "There was always a 'reason' [for the forks, redistributions, and rebundling], at times masked with fake altruism or benevolence. None of these have lasted. They were built to serve their own needs, drive confusion, and splinter the community." Elastic's commercial code may have provided an "inspiration" for others to follow, Banon wrote, but that inspiration didn't necessarily make for clean code. "It has been bluntly copied by various companies and even found its way back to certain distributions or forks, like the freshly minted Amazon one, sadly, painfully, with critical bugs," he wrote.

"The Linux Foundation is launching a new platform designed to sustain open-source communities," reports SD Times: CommunityBridge was announced at this week's Open Source Leadership Summit. The Linux Foundation plans to launch a number of tools to the open-source community throughout the next two years.

The platform is currently being released with Community Bridge Funding to help developers raise and spend funding; CommunityBridge Security for potential vulnerabilities and fixes; and CommunityBridge People for networking and making connections with mentors and mentees.
"In making the announcement, Jim Zemlin, executive director of the Linux Foundation, said on stage at the conference that the Linux Foundation would match funding for any organization that donated funds to CommunityBridge projects," reports FierceTelecom.

"Following up on those announcements, Microsoft-owned GitHub said it would donate $100,000 to CommunityBridge and invited maintainers of CommunityBridge projects to take part in GitHub's maintainer program."

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."

Microsoft said today it has made the source code for its Windows calculator available on GitHub. The company said it hopes to work with contributors to improve the user experience of Windows calculator. In a statement, Dave Grochocki and Howard Wolosky of Microsoft said: Today, we're excited to announce that we are open sourcing Windows Calculator on GitHub under the MIT License. This includes the source code, build system, unit tests, and product roadmap. Our goal is to build an even better user experience in partnership with the community. We are encouraging your fresh perspectives and increased participation to help define the future of Calculator. As developers, if you would like to know how different parts of the Calculator app work, easily integrate Calculator logic or UI into your own applications, or contribute directly to something that ships in Windows, now you can. Calculator will continue to go through all usual testing, compliance, security, quality processes, and Insider flighting, just as we do for our other applications.

Last December, Microsoft announced that it has embraced Google's Chromium open source project for Edge development on the desktop, a move that shocked many. We now have some leaked screenshots of the browser in its current state, and they appear to show a browser resembling Google Chrome. Neowin reports: A lot of the design language and icons have remained similar to what they were like before, but there are definitely many changes that will be familiar to Chrome users. For one, the options to see all your tabs and to set aside the currently open tabs have been removed compared to the current version of Edge. To the right of the address bar, you'll be able to find your extensions, as well as your profile picture similar to what Chrome looks like. Bing is integrated into the browser -- as you'd expect of a Microsoft-made browser -- and the New Tab background can be set to rotate based on Bing's image of the day. Scrolling down will reveal a personalized news feed powered by Microsoft News, similar to the old Edge. The layout of the feed can be customised based on your preference from among a number of options.

The settings options for the browser have also changed. While Edge settings are currently available via a slide-out menu from the right, the new Edge's settings are accessible through a new tab similar to Chrome. It'll show the Microsoft account you're logged into, as well as the usual array of toggles and tidbits you'd expect. Ominously, the about page for the browser now acknowledges the contributions of the Chromium project, as well as other open source software, a stark reminder that this isn't the Microsoft of yesteryear. This is a new browser, and a new Microsoft.
