Version 9.4 of the GNU Compiler Collection "encompasses more than 190 bug fixes for GCC 9.3, which has been available since March 2020," reports DevClass.

But they add that in addition, "Developers who want to contribute to the GNU Compiler Collection but don't feel like signing over copyright to the Free Software Foundation can get busy committing now." GCC Steering Committee member David Edelsohn informed contributors via the mailing list that the committee "decided to relax the requirement to assign copyright for all changes" to the FSF. Speaking for the committee, he wrote that the GCC project "will now accept contributions with or without an FSF copyright assignment", a practice thought of as consistent with that "of many other major Free Software projects, such as the Linux kernel". GCC "will continue to be developed, distributed and licensed" under the GPLv3, so nothing should change for those adding to the project under the old assumptions.

There are those who have had troubles with that arrangement before, with Apple often cited as a popular example. They are now free to contribute utilising the Developer Certificate of Origin instead of agreeing to an FSF Copyright Assignment.

A reason was not given, though the last sentence of the statement, which affirms the principles of Free Software, might give a clue. In March 2021, the committee commented on the removal of Richard Stallman from the project's steering committee website with a similar declaration... [T]hey felt like an association with Stallman was not serving the best interests of the GCC developers and user community, given that the "GCC Steering Committee is committed to providing a friendly, safe and welcoming environment for all."
The Register notes that Red Hat senior principal engineer Mark Wielaard asked why there was no public discussion before making the change.

"Microsoft has announced general availability of the Microsoft Build of OpenJDK, the open-source version of the Java development kit," reports ZDNet: The release follows the April preview of the Microsoft Build of OpenJDK, a long-term support distribution of OpenJDK... Microsoft announced general availability for the Microsoft Build of OpenJDK at its Build 2021 conference for developers.

Microsoft is a major user of Java in Azure, SQL Server, Yammer, Minecraft, and LinkedIn, but it's only been supporting Java in Visual Studio Code tooling for the past five years. "We've deployed our own version of OpenJDK on hundreds of thousands of virtual machines inside Microsoft and LinkedIn," Julia Liuson, corporate vice president of Microsoft's developer division, told ZDNet. "Across the board Microsoft has over 500,000 VMs running Java at Microsoft. We're also providing that to customers as well for Azure...."

"We believe Microsoft is uniquely positioned to be a partner in the language community. We can do a lot of direct contribution to the JDK community and we do world-class tooling, which is VS Code." Microsoft's contributions to OpenJDK — an open-source JDK for the most popular Linux distributions — includes work on the garbage collector and writing capabilities for the Java runtime.

The Microsoft Build of OpenJDK is available for free to deploy in qualifying Azure support plans. It includes binaries for Java 11 based on OpenJDK 11.0.11, on x64 server, and desktop environments on macOS, Linux and Windows, according to Microsoft...
Its download page at Microsoft.com touts it as "Free. Open Source. Freshly Brewed!"

And they describe it as "a new no-cost long-term supported distribution and Microsoft's new way to collaborate and contribute to the Java ecosystem."

John Sullivan became the Free Software Foundation's Executive Director back in 2010. But now after 11 years, "I've decided to resign my position..." he tweeted Friday, "effective at the end of a transition period."

"We'll be sharing further details, including information about that transition, and a few more words, in the coming days."

Meanwhile, the Free Software Foundation announced Thursday that it's seeking "a principled, compassionate, and capable leader" to be its new executive director, working remotely out of their Boston office with the Foundation's current staff and board of directors. "The executive director, working with the president, is the public face of the Foundation." The FSF faces many challenges as software becomes increasingly central in the exercise of all fundamental human freedoms, including speech, association, privacy, and movement, and as software owners seek to exploit their control over us to profit at the expense of those freedoms. The executive director has a vital role in enabling the FSF to continue meeting these challenges, starting from the strong base that has been built in the last thirty-five years. The Foundation has recently reached record-high membership numbers and was awarded a perfect score from Charity Navigator, as well as its eighth consecutive four-star rating. Efforts to improve the Foundation's governance are underway.

The executive director is the FSF's chief employed officer. The position reports to the president/CEO and the board of directors, and is responsible for management of all other staff, all day-to-day operations, and oversight of the Boston physical office. The successful candidate will have the opportunity to hire for additional key positions in the management team.
One interesting item on their list of job responsibilities:

• Mentor, inspire, coordinate, and manage all FSF staff, building a culture that upholds the FSF's ideological principles and includes accountability, empathy, efficiency, and excellence

A blog post on the FSF site also notes that the last month saw 11 new GNU releases. "A number of GNU packages, as well as the GNU operating system as a whole, are looking for maintainers and other assistance: please see https://www.gnu.org/server/takeaction.html#unmaint if you'd like to help."

A group of Redditors came together in a bid to archive over 85 million scientific papers from the website Sci-Hub and make an open-source library that cannot be taken down. Interesting Engineering reports: Over the last decade or so, Sci-Hub, often referred to as "The Pirate Bay of Science," has been giving free access to a huge database of scientific papers that would otherwise be locked behind a paywall. Unsurprisingly, the website has been the target of multiple lawsuits, as well as an investigation from the United States Department of Justice. The site's Twitter account was also recently suspended under Twitter's counterfeit policy, and its founder, Alexandra Elbakyan, reported that the FBI gained access to her Apple accounts.

Now, Redditors from a subreddit called DataHoarder, which is aimed at archiving knowledge in the digital space, have come together to try to save the numerous papers available on the website. In a post on May 13, the moderators of r/DataHoarder, stated that "it's time we sent Elsevier and the USDOJ a clearer message about the fate of Sci-Hub and open science. We are the library, we do not get silenced, we do not shut down our computers, and we are many." This will be no easy task. Sci-Hub is home to over 85 million papers, totaling a staggering 77TB of data. The group of Redditors is currently recruiting for its archiving efforts and its stated goal is to have approximately 8,500 individuals torrenting the papers in order to download the entire library. Once that task is complete, the Redditors aim to release all of the downloaded data via a new "uncensorable" open-source website.

For over an hour on Saturday, retired Microsoft OS developer David Plummer answered questions from his viewers on YouTube.

Long-time Slashdot reader destinyland writes: He began with an update on a project to test the performance of the same algorithm using 30 different programming languages, and soon tells the story of how he was inspired to apply for his first job at Microsoft after reading Hard Drive: Bill Gates and the Making of the Microsoft Empire.

I decided that this is where I wanted to work, because these guys sound like me, they act like me, they are what I want to be when I grow up. And holy cow, they pay them well, apparently. So I wrote to everybody that I could find that had a Microsoft email address, which was about four people, because I had a software product people had been regisering on the Amiga. And one guy, Alistair Banks... responded and he hooked me up with a hiring manager directly in Windows that had an open slot that was hiring... And a couple of interview slots later, I wound up as an intern at MS-DOS working for Ben Slivka.

So you would think, "Oh, an intern on MS-DOS. What'd you do? Format disks?" No — it's amazing to me, actually. They give you as much work as they believe that you are capable of, and — they get you for all that you're worth, basically. They had me write a bunch of major features, like the Smart Drive cache for CD-ROMs was the first thing I wrote. Then I wrote DISKCOPY, making it work, single pass, bunch of features in MS-DOS. I re-wrote Setup to work on a single floppy disk by using deltas and patching in place, DOS 5 to turn it into DOS 6, something like, or maybe it was DOS 6 into 6.2... A whole bunch of features, within the span of, like, three months, which to me was fairly impressive at the time, I thought. And that only got me an interview...

Later he says that he'd like to see most of 16-bit Windows and all of MS-DOS open sourced, along with some select application code from that era.

I don't think there's any reason to hold back any of MS-DOS at this point. They have absolutely no reason to open source any of it, really — other than PR, because all it brings them is potential liability, complaints and angst, and probably nothing positive for putting the code out there and exposing it to ridicule. Because it's ancient code at this point. It's like, "Ha! Look what Microsoft did!" Well, yeah, I know Linux is cool now, but go look at Linux code from 1991 — and I worked on some of that code. Well, '93 I did. It's not the same as what you see today.

So yeah, MS-DOS probably looks archaic — although it's super tight, it doesn't have many bugs. It's just written differently than you would write code today, because you're targetting something that is a very different CPU and memory system and PC as a whole, and it's so much more limited that everybody's sacred, every cycle matters. That kind of thing that you don't worry about now. But I'd still like to see all the code from back then that's not embarrassing released.

And when asked what he misses most about being a Microsoft developer, he answers:

I miss going for lunch with the people that I went for lunch with, and talking to the people that I worked with. Because they were a lot like me, they had similar interests, they had similar abilities, they were people like me. We went for lunch, we ate food, it was awesome, and then we talked about cool things. And we did that every day. And now I don't get to do that any more. I get to do it rarely, because I take guys out for lunch and stuff, but it's not the same. So that's really what I miss.

And I miss somebody always feeding me something interesting to do. Because now I have to go out and find something that's interesting to do on my own. And I can't make everything be monetarily remunerative...

Quoting the Google Developers blog: Developers around the world are constantly creating open source tools and tutorials but have a hard time getting them discovered. The content published often spanned many different sites - from GitHub to Medium. Therefore we decided to create a space where we can highlight the best projects related to Google technologies in one place - introducing the Developer Library.

The platform showcases blog posts and open source tools with easy-to-use navigation. Content is categorized by product areas; Machine Learning, Flutter, Firebase, Angular, Cloud, Android, with more to come.

What makes the Developer Library unique is that each piece featured on the site is reviewed, in detail, by a team of Google experts for accuracy and relevancy, so you know when you view the content on the site it has the stamp of approval from Google.
The "Dev Library" web site describes itself as "a showcase of what developers like you have built with Google technologies."

Microsoft has open-sourced today a tool that can be used to build lab environments where security teams can simulate attacks and verify the detection effectiveness of Microsoft security products. The Record reports: Named SimuLand, the tool was specifically built to help security/IT teams that use Microsoft products such as Microsoft 365 Defender, Azure Defender, and Azure Sentinel. Currently, SimuLand comes with only one lab environment, specialized in detecting Golden SAML attacks. However, Microsoft said it's working on adding new ones. Community contributions are also welcomed, and the reason the project has been open-sourced on GitHub, with Microsoft hoping to get a helping hand from the tens of thousands of security teams that run its software.

"If you would like to share a new end-to-end attacker path, let us know by opening an issue in our GitHub repository, and we would be happy to collaborate and provide some resources to make it happen," Microsoft said today in a blog post. But Microsoft doesn't want only lab environments specialized in executing well-known techniques or adversary tradecraft. The OS maker is also encouraging the community to contribute improved detection rules for the attacks they're sharing, so everyone can benefit from the shared knowledge.

After its recent announcement about plans to add telemetry collection prompted backlash, popular audio editor Audacity has announced it won't go ahead with the plan to collect its users' data. BetaNews reports: Audacity's new owner, Muse Group, has bowed to pressure from users and privacy advocates, announcing that the planned telemetry collection will no longer be going ahead. The company is blaming "communication mistakes" and public "misunderstanding" for the negative response to its previous data collection announcement.

System76 today unveiled its newest product -- the "Launch Configurable Keyboard." It is a mechanical keyboard made in the USA with a focus on open source. The Launch has both open source firmware and hardware. Even the configuration software -- which runs on Linux, Windows, and macOS -- is open source. From a report: "With a wide swath of customization options, the Launch is flexible to a variety of needs and use cases. The keyboard's thoughtful design keeps everything within reach, vastly reducing awkward hand contortions. Launch comes with additional keycaps and a convenient keycap puller, meaning one can swap keys based on personal workflow preferences to maximize efficiency. Launch also features a novel split Space Bar, which allows the user to swap out one Space Bar keycap for Shift, Backspace, or Function to reduce hand fatigue while typing. Launch uses only three keycap sizes to vastly expand configuration options," says System76. The keyboard, which has a removable USB-C cable for connectivity, is priced at $285.

This week Linus Torvalds continued a long email interview with Jeremy Andrews, founding partner/CEO of Tag1 (a global technology consulting firm and the second all-time leading contributor to Drupal). In the first part Torvalds had discussed everything from Apple's ARM64 chips and Rust drivers, to his own Fedora-based home work environment — and reflections on the early days of Linux.

But the second part offers some deeper insight into the way Torvalds thinks, some personal insight, what he'd share with other project maintainers — and some thoughts on getting corporations to contribute to open source development: While open source has been hugely successful, many of the biggest users, for example corporations, do nothing or little to support or contribute back to the very open source projects they rely on. Even developers of surprisingly large and successful projects (if measured by number of users) can be lucky to earn enough to buy coffee for the week. Do you think this is something that can be solved? Is the open source model sustainable?

Linus Torvalds: I really don't have an answer to this, and for some reason the kernel has always avoided the problem. Yes, there are companies that are pure "users" of Linux, but they still end up wanting support, so they then rely on contractors or Linux distributions, and those obviously then end up as one of the big sources of kernel developer jobs.

And a fair number of big tech companies that use the kernel end up actively participating in the development process. Sometimes they end up doing a lot of internal work and not being great at feeding things back upstream (I won't name names, and some of them really are trying to do better), but it's actually very encouraging how many big companies are very openly involved with upstream kernel development, and are major parts of the community.

So for some reason, the kernel development community has been pretty successful about integrating with all the commercial interests. Of course, some of that has been very much conscious: Linux has very much always been open to commercial users, and I very consciously avoided the whole anti-corporate mindset that you can most definitely find in some of the "Free Software" groups. I think the GPLv2 is a great license, but at the same time I've been very much against some of the more extreme forms of "Free Software", and I — and Linux — was very much part of the whole rebranding to use "Open Source".

Because frankly, some of the almost religious overtones of rms and the FSF were just nutty, and a certain portion of the community was actively driving commercial use away.

And I say that as somebody who has always been wary of being too tainted by commercial interests... I do think that some projects may have shot themselves in the foot by being a bit too anti-commercial, and made it really hard for companies to participate...

But is it sustainable? Yes. I'm personally 100% convinced that not only is open source sustainable, but for complex technical issues you really need open source simply because the problem space ends up being too complex to manage inside one single company. Even a big and competent tech company.

But it does require a certain openness on both sides. Not all companies will be good partners, and some developers don't necessarily want to work with big companies.
In the interview Torvalds also thanks the generous education system in Finland, and describes what it was like moving from Finland to America. And as for how long he'll continue working on Linux, Torvalds says, "I do enjoy what I do, and as long as I feel I'm actually helping the project, I'll be around...

"in the end, I really enjoy what I do. I'd be bored to tears without kernel development."

"The Linux Foundation has lifted the lid on a new open source digital infrastructure project aimed at the agriculture industry," reports VentureBeat: The AgStack Foundation, as the new project will be known, is designed to foster collaboration among all key stakeholders in the global agriculture space, spanning private business, governments, and academia.

As with just about every other industry in recent years, there has been a growing digital transformation across the agriculture sector that has ushered in new connected devices for farmers and myriad AI and automated tools to optimize crop growth and circumvent critical obstacles, such as labor shortages. Open source technologies bring the added benefit of data and tools that any party can reuse for free, lowering the barrier to entry and helping keep companies from getting locked into proprietary software operated by a handful of big players...

The AgStack Foundation will be focused on supporting the creation and maintenance of free and sector-specific digital infrastructure for both applications and the associated data. It will lean on existing technologies and agricultural standards; public data and models; and other open source projects, such as Kubernetes, Hyperledger, Open Horizon, Postgres, and Django, according to a statement.

"Current practices in AgTech are involved in building proprietary infrastructure and point-to-point connectivity in order to derive value from applications," AgStack executive director Sumer Johal told VentureBeat. "This is an unnecessarily costly use of human capital. Like an operating system, we aspire to reduce the time and effort required by companies to produce their own proprietary applications and for content consumers to consume this interoperably."

A U.K. company behind digital addressing system What3Words has sent a legal threat to a security researcher for offering to share an open-source software project with other researchers, which What3Words claims violate its copyright. From a report: Aaron Toponce, a systems administrator at XMission, received a letter on Thursday from London-based law firm JA Kemp representing What3Words, requesting that he delete tweets related to the open-source alternative, WhatFreeWords. The letter also demands that he disclose to the law firm the identity of the person or people with whom he had shared a copy of the software, agree that he would not make any further copies of the software and to delete any copies of the software he had in his possession. The letter gave him until May 7 to agree, after which What3Words would "waive any entitlement it may have to pursue related claims against you," a thinly-veiled threat of legal action. "This is not a battle worth fighting," he said in a tweet.

Toponce told TechCrunch that he has complied with the demands, fearing legal repercussions if he didn't. He has also asked the law firm twice for links to the tweets they want deleting but has not heard back. "Depending on the tweet, I may or may not comply. Depends on its content," he said. U.K.-based What3Words divides the entire world into three-meter squares and labels each with a unique three-word phrase. The idea is that sharing three words is easier to share on the phone in an emergency than having to find and read out their precise geographic coordinates. But security researcher Andrew Tierney recently discovered that What3Words would sometimes have two similarly-named squares less than a mile apart, potentially causing confusion about a person's true whereabouts. In a later write-up, Tierney said What3Words was not adequate for use in safety-critical cases.

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."

Linus Torvalds gave a long new email interview to Jeremy Andrews, founding partner/CEO of Tag1 (a global technology consulting firm and the second all-time leading contributor to Drupal). Torvalds discusses everything from the creation of Git, licenses, Apple's ARM64 chips, and Rust drivers, to his own Fedora-based home work environment — and how proud he is of the pathname lookup in Linux's virtual filesystem. ("Nothing else out there comes even close.")

But with all that, early on Torvalds also reflects that Linux began as a personal project at the age of 21, "not out of some big dream to create a new operating system." Instead it "literally grew kind of haphazardly from me initially just trying to learn the in-and-outs of my new PC hardware.

"So when I released the very first version, it was really more of a 'look at what I did', and sure, I was hoping that others would find it interesting, but it wasn't a real serious and usable OS. It was more of a proof of concept, and just a personal project I had worked on for several months at that time..."

This year, in August, Linux will celebrate its 30th anniversary! That's amazing, congratulations! At what point during this journey did you realize what you'd done, that Linux was so much more than "just a hobby"?

Linus Torvalds: This may sound a bit ridiculous, but that actually happened very early. Already by late '91 (and certainly by early '92) Linux had already become much bigger than I had expected.

And yeah, considering that by that point, there were probably just a few hundred users (and even "users" may be too strong — people were tinkering with it), it probably sounds odd considering how Linux then later ended up growing much bigger. But in many ways for me personally, the big inflection point was when I realized that other people are actually using it, and interested in it, and it started to have a life of its own. People started sending patches, and the system was actually starting to do much more than I had initially really envisioned....

That "anybody can maintain their own version" worried some people about the GPLv2, but I really think it's a strength, not a weakness. Somewhat unintuitively, I think it's actually what has caused Linux to avoid fragmenting: everybody can make their own fork of the project, and that's OK. In fact, that was one of the core design principles of "Git" — every clone of the repository is its own little fork, and people (and companies) forking off their own version is how all development really gets done.

So forking isn't a problem, as long as you can then merge back the good parts. And that's where the GPLv2 comes in. The right to fork and do your own thing is important, but the other side of the coin is equally important — the right to then always join back together when a fork was shown to be successful...

I very much don't regret the choice of license, because I really do think the GPLv2 is a huge part of why Linux has been successful.

Money really isn't that great of a motivator. It doesn't pull people together. Having a common project, and really feeling that you really can be a full partner in that project, that motivates people, I think.

Long-time Slashdot reader destinyland writes: This week the Free Software Foundation posted some new answers to frequently-asked questions "as the FSF board sets about the work of strengthening the Foundation's governance structure." The FAQ notes that most of their financial support comes from individuals, and that "At this moment, the FSF has more associate members than at any time in its history," adding that it's in good financial health. (And the FAQ also reminds readers that all board members are uncompensated volunteers.)

But it also confirms that a seat on the board was created for union staff "in the aftermath of the March 2021 controversy over the election of Richard Stallman to the board." And apparently in light of Stallman's return, the first question is "What are the responsibilities of a member of the FSF board?"

Answer: The board of directors does not usually deal with the everyday work of the FSF, focusing instead on the long-term direction and financial stability of the Foundation, as well as the appointment of the officers. In addition, members of the board do not speak for the board or for the FSF. Outside of the deliberations of the board, they are private citizens. The right to speak for the Foundation is reserved to the president of the FSF and other FSF officers, such as the executive director.

When the board does make statements, each statement is carefully deliberated. No one member has this individual authority.

The FAQ also clarifies that while Stallman is also a voting board member, "Voting member meetings normally discuss only who should be on the board. They do not take up the issues that come before the board itself... When the Foundation was formed in 1985, the founders were advised that, to qualify for a tax exemption, board members should not be chosen solely by other board members. Legal counsel advised the founders that there should be two bodies with some overlap, one being the active board and the other being a body that appointed the active board.

"Governance standards have since changed, and this structure is no longer required. As part of the effort to improve FSF governance, the board can consider possible changes to this overall structure."

It also adds that "There is no formal term limit for a board member. Board members are evaluated by the voting members at regular intervals, and occasionally by the other directors."

The last question on the list? "In addition to holding a board seat, what other role or roles does Richard Stallman play in the FSF?"

The answer? "Richard Stallman frequently gives talks on free software, in his personal capacity, and, when he does so, he sells merchandise from the FSF shop, recruits volunteers for FSF and GNU, and raises donations for FSF. He is the primary author and editor of two books sold by the FSF."

Saturday University of Minnesota researchers emailed the Linux kernel mailing list apologizing for submitting buggy code as part of a research project to see whether it would be accepted.

Late Saturday night, the kernel team's Greg Kroah-Hartman replied: Thank you for your response.

As you know, the Linux Foundation and the Linux Foundation's Technical Advisory Board submitted a letter on Friday to your University outlining the specific actions which need to happen in order for your group, and your University, to be able to work to regain the trust of the Linux kernel community.

Until those actions are taken, we do not have anything further to discuss about this issue.

thanks

An anonymous reader quotes a report from ZDNet: A small miracle happened at 3:31am ET on Monday morning. Ingenuity, a tiny NASA helicopter, became the first powered aircraft to fly on another planet, Mars. This engineering feat was done with Linux, open-source software, and a NASA-built program based on the Jet Propulsion Laboratory's (JPL) open-source F (pronounced F prime) framework. GitHub CEO Nat Friedman and his team and the JPL Ingenuity crew took a long hard look into the helicopter's code and found that "nearly 12,000 developers on GitHub contributed to Ingenuity's software via open source. And yet, much like the first image of a black hole, most of these developers are not even aware that they helped make the first Martian helicopter flight possible."

They'll know now. Friedman wrote: "Today, we want to make the invisible visible. So, we have worked with JPL to place a new Mars 2020 Helicopter Mission badge on the GitHub profile of every developer who contributed to the specific versions of any open-source projects and libraries used by Ingenuity." The developer list was created by JPL providing GitHub with a comprehensive list of every version of every open source project used by Ingenuity. GitHub could then identify all the contributors who made these projects and their dependencies. Some of those honored, such as Linux's creator Linus Torvalds, are famous developers. Many others labor in obscurity -- but now their work is being recognized. Timothy Canham, a JPL embedded flight software engineer, notes Ingenuity's program is powered by a Qualcomm Snapdragon 801 running at 2.2GHz, which is "far faster than the Mars Perseverance's rover processors," according to ZDNet. The reason this older chip was used is because it meets NASA's High-Performance Spaceflight Computing (HPSC) radiation standards.

Canham also says the flight control software on Ingenuity runs at 500Hz. The flight software "is used to control the flight hardware and read sensors 500 times per second in order to keep the helicopter stable." Canham added: "We literally ordered parts from SparkFun [Electronics]. This is commercial hardware, but we'll test it, and if it works well, we'll use it."

Long-time Slashdot reader xiando shares news from LinuxReviews: Linux Kernel Runtime Guard (LKRG) is a security module for the Linux kernel developed by Openwall. The latest release adds compatibility with Linux kernels up to soon to be released 5.12, support for building LKRG into kernel images, support for old 32-bit x86 machines and more...

The Linux Kernel Runtime Guard is an out-of-tree kernel module you can install as a kernel module, or, with the 0.9.0 release, build into your Linux kernel. It does run-time integrity checks to detect security vulnerability exploits against the Linux kernel.
An Openwall developer also notes in the announcement that "During LKRG development and testing I've found 7 Linux kernel bugs, 4 of them have CVE numbers."

"FreeBSD, the other Linux, reached version 13," writes long-time Slashdot reader undoman. "The operating system is known for its stable code, native ZFS support, and use of the more liberal BSD licenses." Phoronix highlights some of the major new improvements: FreeBSD 13.0 delivers on performance improvements (particularly for Intel CPUs we've seen in benchmarks thanks to hardware P-States), upgrading to LLVM Clang 11 as the default compiler toolchain, POWER 64-bit support improvements, a wide variety of networking improvements, 64-bit ARM (AArch64) now being a tier-one architecture alongside x86_64, EFI boot improvements, AES-NI is now included by default for generic kernel builds, the default CPU support for i386 is bumped to i686 from i486, and a variety of other hardware support improvements. Various obsolete GNU tools have been removed like an old version of GNU Debugger used for crashinfo, obsolete GCC 4.2.1 and Binutils 2.17 were dropped from the main tree, and also switching to a BSD version of grep.
