The Washington Post reports Russian troops in Ukraine "have relied, with surprising frequency, on unsecured communication devices such as smartphones and push-to-talk radios."

But this is leaving Russia's units "vulnerable to targeting...further underscoring the command-and-control deficiencies that have come to define Moscow's month-long invasion, observers say." The Russian military possesses modern equipment capable of secure transmission, but troops on the battlefield have reached for simpler-to-use but less-secure lines because of uneven discipline across the ranks, an apparent lack of planning for conducting a sustained fight over long distances, and Russian attacks on Ukraine's communication infrastructure that it, too, has relied on, experts say.

A European intelligence official, speaking on the condition of anonymity to discuss NATO's battlefield assessments, said that since the invasion began in late-February, there have been multiple instances of Russian commanders confiscating their subordinates' personal phones for fear they would unwittingly give away a unit's location.... There is evidence that the United States and other NATO countries have provided Ukrainian forces with electronic warfare equipment capable of interrupting Russian transmissions and allowing them to target Russian command posts, said Kostas Tigkos, a Russian military expert at the defense analysis firm Janes Group. By destroying Russia's communication nodes, the Ukrainians could pressure their adversaries to use less-secure equipment, he said, increasing the likelihood their conversations will be intercepted or their positions triangulated....

There is anecdotal evidence that Russia's unsecured communications have led to battlefield losses. One Russian general was purportedly killed in an airstrike after his cellphone was detected by the Ukrainians, the New York Times reported earlier this month.
The Post reports that Russian military transmissions over unsecured lines are now even being listened to by amateur radio enthusiasts at online sites like WebSDR (a software-defined radio receiver connected to the internet).

"Don't say the last names on air!" one Russian service member was apparently overheard saying by Shadow Break International, a U.K.-based open-source intelligence consultancy.

Sony is preparing to introduce a new video game subscription service for the PlayStation as early as next week, Bloomberg News reported Friday, citing people familiar with the plans. From the report: The service, which has been in development under the codename Spartacus, is Sony's answer to Microsoft's Xbox Game Pass, a sort of Netflix for video games that has amassed more than 25 million subscribers. Sony's will debut with a splashy lineup of hit games from recent years, said the people, who requested anonymity because the plans are private. Sony's new service will combine two of its current offerings, PlayStation Now and PlayStation Plus. Customers will be able to choose from multiple tiers offering catalogs of modern games and classics from older PlayStation eras.

Come July, the EPA plans to retire the archive containing old news releases, policy changes, regulatory actions, and more. The Verge reports: The archive was never built to be a permanent repository of content, and maintaining the outdated site was no longer "cost effective," the EPA said to The Verge in an emailed statement. The EPA announced the retirement early this year, after finishing an overhaul of its main website in 2021, but says that the decision was years in the making. The agency maintains that it's abiding by federal rules for records management and that not all webpages qualify as official records that need to be preserved.

The EPA says it plans to migrate much of the information to other places. Old news releases will go to the current EPA website's page for press releases. When it comes to the rest of the content, the EPA has a process for making case-by-case decisions on what content can be deleted -- and what is relevant enough to move to the modern website. Some content might be deemed important enough to join the National Archives. The public will be able to request that content through the Freedom of Information Act.

The archive is the only comprehensive way that public information about agency policies, like fact sheets breaking down the impact of environmental legislation, and actions, like how the agency implements those laws, have been preserved, [says Gretchen Gehrke, one of the cofounders of a group called Environmental Data and Governance Initiative (EDGI) that's fighting for public access to resources like the EPA's online archives]. That makes the archive vital for understanding how regulation and enforcement have changed over the years. It also shows how the agency's understanding of an issue, like climate change, has evolved. And when the Trump administration deleted information about climate change on the EPA's website, much of it could still be found on the archive. Besides that, Gehrke says the content should just be available on principle because it's public information, paid for by taxpayer dollars.

"Supporting generics has been Go's most often requested feature, and we're proud to deliver the generic support that the majority of users need today," the Go blog announced this week. *

It's part of what Go's development team is calling the "biggest change ever to the language".

SiliconANGLE writes that "Right out of the gate, Go 1.18 is getting a CPU speed performance boost of up to 20% for Apple M1, ARM64 and PowerPC64 chips. This is all from an expansion of Go 1.17's calling conventions for the application binary interface on these processor architectures."

And Go 1.18 also introduces native support for fuzz testing — the first major programming language to do so, writes ZDNet: As Google explains, fuzz testing or 'fuzzing' is a means of testing the vulnerability of a piece of software by throwing arbitrary or invalid data at it to expose bugs and unknown errors. This adds an additional layer of security to Go's code that will keep it protected as its functionality evolves — crucial as attacks on software continue to escalate both in frequency and complexity. "At Google we are committed to securing the online infrastructure and applications the world depends upon," said Eric Brewer, VIP infrastructure at Google....

While other languages support fuzzing, Go is the first major programming language to incorporate it into its core toolchain, meaning — unlike other languages — third-party support integrations aren't required.
Google is emphasizing Go's security features — and its widespread adoption. ZDNet writes: Google created Go in 2007 and was designed specifically to help software engineers build secure, open-source enterprise applications for modern, multi-core computing systems. More than three-quarters of Cloud Native Computing Foundation projects, including Kubernetes and Istio, are written in Go, says Google. [Also Docker and Etc.] According to data from Stack Overflow, some 10% of developers are writing in Go worldwide, and there are signs that more recruiters are seeking out Go coders in their search for tech talent..... "Although we have a dedicated Go team at Google, we welcome a significant amount of contributions from our community. It's a shared effort, and with their updates we're helping our community achieve Go's long-term vision.
Or, as the Go blog says: We want to thank every Go user who filed a bug, sent in a change, wrote a tutorial, or helped in any way to make Go 1.18 a reality. We couldn't do it without you. Thank you.

Enjoy Go 1.18!
* Supporting generics "includes major — but fully backward-compatible — changes to the language," explains the release notes. Although it adds a few cautionary notes: These new language changes required a large amount of new code that has not had significant testing in production settings. That will only happen as more people write and use generic code. We believe that this feature is well implemented and high quality. However, unlike most aspects of Go, we can't back up that belief with real world experience. Therefore, while we encourage the use of generics where it makes sense, please use appropriate caution when deploying generic code in production.

While we believe that the new language features are well designed and clearly specified, it is possible that we have made mistakes.... it is possible that there will be code using generics that will work with the 1.18 release but break in later releases. We do not plan or expect to make any such change. However, breaking 1.18 programs in future releases may become necessary for reasons that we cannot today foresee. We will minimize any such breakage as much as possible, but we can't guarantee that the breakage will be zero.

"Asahi Linux aims to bring you a polished Linux experience on Apple Silicon Macs," explains the project's web site.

And now that first Asahi Linux alpha release is out — ready for testing on M1, M1 Pro, and M1 Max machines (except Mac Studio): We're really excited to finally take this step and start bringing Linux on Apple Silicon to everyone. This is only the beginning, and things will move even more quickly going forward!

Keep in mind that this is still a very early, alpha release. It is intended for developers and power users; if you decide to install it, we hope you will be able to help us out by filing detailed bug reports and helping debug issues. That said, we welcome everyone to give it a try — just expect things to be a bit rough.... Asahi Linux is developed by a group of volunteers, and led by marcan as his primary job. You can support him directly via Patreon and GitHub Sponsors....

Can I dual-boot macOS and Linux?

Yes! In fact, we expect you to do that, and the installer doesn't support replacing macOS at this point. This is because we have no mechanism for updating system firmware from Linux yet, and until we do it makes sense to keep a macOS install lying around for that. You can have as many macOS and Linux installs as you want, and they will all play nicely and show up in Apple's boot picker. Each Linux install acts as a self-contained OS and should not interfere with the others.

Note that keeping a macOS install around does mean you lose ~70GB of disk space (in order to allow for updates, since the macOS updater is quite inefficient). In the future we expect to have a mechanism for firmware updates from Linux and better integration, at which point we'll be comfortable recommending Linux-only setups....

Is this just Arch Linux ARM?

Pretty much! Most of our work is in the kernel and a few core support packages, and we rely on Linux's excellent existing ARM64 support. The Asahi Linux reference distro images are based off of Arch Linux ARM and simply add our own package repository, which only adds a few packages. You can freely convert between Arch Linux ARM and Asahi Linux by adding or removing this repository and the relevant packages, although vanilla Arch Linux ARM kernels will not boot on these machines at this time.
The project's home page adds that "All contributors are welcome, of any skill level!"

"Doing this requires a tremendous amount of work, as Apple Silicon is an entirely undocumented platform," the team explains. "In particular, we will be reverse engineering the Apple GPU architecture and developing an open-source driver for it." But they're already documenting the Apple Silicon platform on their GitHub wiki. We will eventually release a remix of Arch Linux ARM, packaged for installation by end-users, as a distribution of the same name. The majority of the work resides in hardware support, drivers, and tools, and it will be upstreamed to the relevant projects....

Apple allows booting unsigned/custom kernels on Apple Silicon Macs without a jailbreak! This isn't a hack or an omission, but an actual feature that Apple built into these devices. That means that, unlike iOS devices, Apple does not intend to lock down what OS you can use on Macs (though they probably won't help with the development). As long as no code is taken from macOS to build the Linux support, the result is completely legal to distribute and for end-users to use, as it would not be a derivative work of macOS.
An interesting observataion from Slashdot reader mrwireless: It once again seems Apple is informally supportive of these efforts, as the recent release of OS Monterey 12.3 makes the process even simpler. As Twitter user Matthew Garrett writes:

"People who hate UEFI should read https://github.com/AsahiLinux/... — Apple made deliberate design choices that allow third party OSes to run on M1 hardware without compromising security, and with much less closed code than on basically any modern x86."

Stephen Hawking's black hole information paradox has bedevilled scientists for half a century and led some to question the fundamental laws of physics. Now scientists say they may have resolved the infamous problem by showing that black holes have a property known as "quantum hair." From a report: If correct, this would mark a momentous advance in theoretical physics. Prof Xavier Calmet, of the University of Sussex, who led the work, said that after working on the mathematics behind the problem for a decade, his team made a rapid advance last year that gave them confidence that they had finally cracked it. "It was generally assumed within the scientific community that resolving this paradox would require a huge paradigm shift in physics, forcing the potential reformulation of either quantum mechanics or general relativity," said Calmet. "What we found -- and I think is particularly exciting -- is that this isn't necessary."

Hawking's paradox boils down to the following: the rules of quantum physics state that information is conserved. Black holes pose a challenge to this law because once an object enters a black hole, it is essentially gone for good -- along with any information encoded in it. Hawking identified this paradox and for decades it has continued to confound scientists. There have been innumerable proposed solutions, including a "firewall theory" in which information was assumed to burn up before entering the black hole, the "fuzzball theory" in which black holes were thought to have indistinct boundaries, and various exotic branches of string theory. But most of these proposals required rewriting of the laws of quantum mechanics or Einstein's theory of gravity, the two pillars of modern physics.

Rockstar's anarchic masterpiece has been freshened up for PlayStation 5 and Xbox Series X nine years after it was originally released. From a report: And so the boys are back in town. Michael, Trevor and Franklin, the sociopathic trio that lit up the gaming scene nine years ago, have been made over for the 2020s with this crisp new reworking of Grand Theft Auto V for PlayStation 5 and Xbox Series X. The game's violent narrative of shifting loyalties and doomed machismo felt wild and edgy back in 2013, so how does it fare in the modern era? The good news is, the overhauled visuals definitely give the game new zest and freshness. You can play in either 4K at 30 frames-per-second or in a performance mode that lowers the resolution but bumps up the frame rate to 60, giving wonderful fluidity to car chases, swooping helicopter rides and mass shootouts. The DualSense controller features on PlayStation 5 are very good too: improved driving feedback via the analogue triggers makes the game's cumbersome handling a little easier to, well, handle. It's been quite a joy to rediscover this alternate-reality California; to see the sun drop behind the downtown skyscrapers, or to hit Senora as dawn splashes orange-yellow light across the burning desert.

What the vast upshift in resolution can't hide is the fact that GTA V is a game originally designed for consoles that are now two generations out of date. The character models and facial details look positively archaic compared with, say, Horizon Forbidden West, and the building architecture too seems almost quaint in its stylised blockiness. Compare it with 2018's Red Dead Redemption 2 and you can see just how far Rockstar has come in its building of intricate next-gen worlds. In many ways, however, the design of the world itself has not been been bettered in the decade since it arrived. The size of San Andreas, the sheer variety of landscapes and the diversity of actions and activities is still incredible -- Cyberpunk 2077 may look better, but it doesn't let you play golf or tennis, or go on day trips on a bike, or set up incredibly complex car or helicopter stunts. Los Santos is a vast playground, a gangster Fortnite -- a factor underlined by the massive community that still gathers in GTA Online (which is where we find this new version's only totally new content -- Hao's Special Works, which lets you unlock faster cars and new tasks).

"News of a fresh Spectre BHB vulnerability that only impacts Intel and Arm processors emerged this week," reports Tom's Hardware, "but Intel's research around these new attack vectors unearthed another issue.

"One of the patches that AMD has used to fix the Spectre vulnerabilities has been broken since 2018." Intel's security team, STORM, found the issue with AMD's mitigation. In response, AMD has issued a security bulletin and updated its guidance to recommend using an alternative method to mitigate the Spectre vulnerabilities, thus repairing the issue anew....

Intel's research into AMD's Spectre fix begins in a roundabout way — Intel's processors were recently found to still be susceptible to Spectre v2-based attacks via a new Branch History Injection variant, this despite the company's use of the Enhanced Indirect Branch Restricted Speculation (eIBRS) and/or Retpoline mitigations that were thought to prevent further attacks. In need of a newer Spectre mitigation approach to patch the far-flung issue, Intel turned to studying alternative mitigation techniques. There are several other options, but all entail varying levels of performance tradeoffs. Intel says its ecosystem partners asked the company to consider using AMD's LFENCE/JMP technique. The "LFENCE/JMP" mitigation is a Retpoline alternative commonly referred to as "AMD's Retpoline."

As a result of Intel's investigation, the company discovered that the mitigation AMD has used since 2018 to patch the Spectre vulnerabilities isn't sufficient — the chips are still vulnerable. The issue impacts nearly every modern AMD processor spanning almost the entire Ryzen family for desktop PCs and laptops (second-gen to current-gen) and the EPYC family of datacenter chips....

In response to the STORM team's discovery and paper, AMD issued a security bulletin (AMD-SB-1026) that states it isn't aware of any currently active exploits using the method described in the paper. AMD also instructs its customers to switch to using "one of the other published mitigations (V2-1 aka 'generic retpoline' or V2-4 aka 'IBRS')." The company also published updated Spectre mitigation guidance reflecting those changes [PDF]....

AMD's security bulletin thanks Intel's STORM team by name and noted it engaged in the coordinated vulnerability disclosure, thus allowing AMD enough time to address the issue before making it known to the public.
Thanks to Slashdot reader Hmmmmmm for submitting the story...

Last Exit: Space is a new documentary on Discovery+ exploring the possibility of humans colonizing planets beyond Earth, reports Ars Technica.. "Since it is produced and narrated by Werner Herzog and written and directed by his son Rudolph, however, it goes in a different direction than your average space documentary. It's weird, beautiful, skeptical, and even a bit funny...."

Other times, Werner opts for dryly funny narration of how bleak certain space colonization efforts may turn out. "The reality of life on Mars would be sobering," he says. "Astronauts would hunker down in radiation-proof bunkers, enjoying drinks of recycled urine...."

For most of the film, Rudolph focuses on two options for where humans might travel, land, and establish space colonies: Mars or an exoplanet in the Alpha Centauri system. Along the way, Last Exit: Space follows a pattern. First, it lists a problem that might make a certain space travel proposition impossible. Then it briefly explains the most promising solution to that problem as developed by modern science and engineering. Finally, it brings the interstellar dream crashing back down to Earth with a grim recounting of why the solution won't work.... "We know the next planet outside of our solar system is at least 5,000 years away," Werner tells Ars. "It's very hard to do that, and [whatever is there is] probably uninhabitable. And we know that on Mars, there's permanent radiation that will force us underground in little bunkers...."

As Last Exit: Space explores the logistics of a possible 5,000-year journey to Alpha Centauri, the film asks wild questions that touch matters of the human spirit, each with a diverse pool of optimistic and pessimistic answers. Is hibernation feasible? Could a non-hibernating skeleton crew function in a sane way? And how would the human act of copulation play out — both mechanically, in terms of being a reduced-gravity exercise, and genetically, in terms of possible in-breeding if a ship can't hold at least 40,000 colonists to keep the gene pool diverse...? [Werner Herzog adds] "But as you hear it from Lucian Walkowicz, an astronomer in the film, it's very clear that we take her position: We shouldn't behave like locusts who are grazing everything empty here, then move on to the next planet. There's something not right to shift, to move our population to other planets, and it's a part of all these ethical questions....

[Space colonization] will fail. It is inevitable. You cannot travel to the next [Alpha Centauri exoplanet] that is 200,000 years away. Period. Good luck...."

The filmmakers make it clear that they admire and appreciate efforts to understand space and our universal neighbors. But in describing "space colonization" as "a dirty word," Rudolph paraphrases Walkowicz's film-ending pitch: "There is already a cross-generational spaceship operating right now — and we're already on it. Earth is a luxuriously furnished, wonderfully self-rejuvenating place, so we'd better treat it well...."

Werner admits that he does have some interest in space travel. "I would love to go out on Mars on a mission... if I had a camera with me," he says.

Rudolph immediately interrupts: "Yes, but I want to stop my dad. Don't encourage him on this, please. I want him to stay on Earth."

An anonymous reader quotes a report from Bloomberg: In early February a black box crammed with computer processors took a flight from California to Uganda. The squat, 4-foot-high box resembled a giant stereo amp. Once settled into place in Kampala, its job was to predict the weather better than anything the nation had used before (Warning: source may be paywalled; alternative source). The California startup that shipped the device, Atmo AI, plans by this summer to swap it out for a grander invention: a sleek, metallic supercomputer standing 8 feet tall and packing in 20 times more power. "It's meant to be the iPhone of global meteorology," says Alexander Levy, Atmo's co-founder and chief executive officer. That's a nod to Apple's design cred and market strategy: In many countries, consumers who'd never owned desktop computers bought smartphones in droves. Similarly, Atmo says, countries without the pricey supercomputers and data centers needed to make state-of-the-art weather forecasts -- effectively, every nation that's not a global superpower -- will pay for its cheaper device instead.

For its first customer, though, the Uganda National Meteorological Authority (UNMA), Atmo is sending its beta version, the plain black box. Prizing function over form seems wise for the urgent problem at hand. In recent years, Uganda has had landslides, floods, and a Biblical plague of locusts that devastated farms. The locusts came after sporadic drought and rain, stunning officials who didn't anticipate the swarms. "It became an eye-opener for us," says David Elweru, UNMA's acting executive director. Many nations facing such ravages lack the most modern tools to plan for the changing climate. Atmo says artificial intelligence programs are the answer. "Response begins with predictions," Levy says. "If we expect countries to react to events only after they've happened, we're dooming people to disaster and suffering." It's a novel approach. Meteorology poses considerable challenges for AI systems, and only a few weather authorities have experimented with it. Most countries haven't had the resources to try.

Ugandan officials signed a multi-year deal with Atmo but declined to share the terms. The UNMA picked the startup partly because its device was "way, way cheaper" than alternatives, according to Stephen Kaboyo, an investor advising Atmo in Uganda. Kaboyo spoke by phone in February, Kampala's dry season, as rain pelted the city. "We haven't seen this before," he said of the weather. "Who knows what is going to happen in the next three seasons?" [...] Atmo reports that its early tests have doubled the accuracy scores of baseline forecasts in Southeast Asia, where the startup is pursuing contracts. Initial tests on the ground in Uganda correctly predicted rainfall when other systems didn't, according to UNMA officials.

Google is updating the default "Messages" app to include a number of new features, such as the ability to handle iMessage "Tapbacks." TechCrunch reports: Other coming updates include nudges to remind you to reply to messages you missed, separate tabs for business and personal messages, reminders about birthdays you may want to celebrate, support for sharper videos via a Google Photos integration and an expanded set of emoji mashups, among other things. After the update, reactions from iPhone users will be sent as an emoji on text messages on Android. As on iMessage, the emoji reaction -- like love, laughter, confusion or excitement -- will appear on the right side of the message. (On Android, it's the bottom right.) This feature is first rolling out to Android devices set to English, but additional languages will follow. [...] Android's interpretation of which emoji to use varies slightly from iPhone, however. For instance, the "heart" reaction on Android becomes the "face with the heart eyes" emoji. And the iMessage's exclamation mark reaction becomes the "face with the open mouth" emoji.

Google is also integrating Google Photos into the Message app to improve the video sharing experience. While the modern RCS standard allows people with Android devices to share high-quality videos with each other, those same videos appear blurry when shared with those on iPhone, as iMessage doesn't support RCS. By sending the link to the video through Google Photos, iPhone users will be able to watch the video in the same high resolution. This feature will later include support for photos, too. This addition aims to push Apple to adopt the industry standard by shaming the company over video quality.

Scientists at NASA's Johnson Space Center in Houston are preparing to open the first tube that one of the astronauts on the Apollo missions hammered into the surface of the moon. As NPR reports, it's "remained tightly sealed all these years since that 1972 Apollo 17 mission -- the last time humans set foot on the moon." From the report: The unsealed tube from that mission was opened in 2019. The layers of lunar soil had been preserved, and the sample offered insight into subjects like landslides in airless places. Because the sample being opened now has been sealed, it may contain something in addition to rocks and soil: gas. The tube could contain substances known as volatiles, which evaporate at normal temperatures, such as water ice and carbon dioxide. The materials at the bottom of the tube were extremely cold at the time they were collected. The amount of these gases in the sample is expected to be very low, so scientists are using a special device called a manifold, designed by a team at Washington University in St. Louis, to extract and collect the gas.

Another tool was developed at the European Space Agency (ESA) to pierce the sample and capture the gases as they escape. Scientists there have called that tool the "Apollo can opener." The careful process of opening and capturing has begun, and so far, so good: the seal on the inner sample tube seems to be intact. Now, the piercing process is underway, with that special "can opener" ready to trap whatever gases might come out. If there are gases in the sample, scientists will be able to use modern mass spectrometry technology to identify them. (Mass spectrometry is a tool for analyzing and measuring molecules.) The gas could also be divided into tiny samples for other researchers to study.

An anonymous reader quotes a report from Bloomberg: Microsoft Corp. has begun calling employees back to its headquarters in recent weeks, but its return-to-office strategy hinges on hybrid work. From Wall Street to Silicon Valley, companies are navigating the messy transition to the workplace after a two-year hiatus during the pandemic. Microsoft has a unique perspective since it sells remote collaboration tools that compete with Zoom and Cisco. Even as workers trickle back to their desks, the company's leaders are focused on those employees who aren't working in the office. "It's counterintuitive," Jared Spataro, corporate vice president for Modern Work at Microsoft, said in an interview. "You have to design your physical space for the people who aren't there."

At The Hive, its test center a few miles from its Redmond, Washington campus, engineers roll office chairs back and forth and shift camera angles around to capture the optimal teleconference environment. Staffers down the hall pose as remote attendees, providing immediate feedback. A full-size replica of a room Chief Executive Officer Satya Nadella and other senior leadership use for top-level meetings fills a warehouse floor. What they've found is that small tweaks can really improve the experience, making those daily calls less of a grind. The typical conference table, for example, was redesigned to a triangle pointed away from the screens, or a truncated semi-circle facing the screen, United Nations-style. Both setups address a big problem with standard conference rooms: Attendees don't fully face the camera, and in-person participants migrate toward each other.

Meantime, at Microsoft's headquarters last week, occupancy jumped 142% from the prior one, according to the company, which declined to provide further details. The mood resembled a college move-in day, with giddy staffers excited to no longer be stuck at home. [...] While Microsoft executives from Nadella on down have been promoting the idea of the so-called metaverse to connect workers in various locations, the company also says it knows it has to take it slow. "We're just trying to meet people where they are," Spataro said. "You kind of have to crawl before you can move to a fully virtual world."

An anonymous reader quotes a report from Ars Technica: Mykhailo Fedorov, the vice prime minister and minister of digital transformation of Ukraine, has publicly called on "all game development companies" to "temporarily block all Russian and Belorussian accounts" in response to Russia's ongoing invasion of Ukraine. In a tweet from his verified account, Fedorov also called on esports platforms to "temporarily stop the participation of Russian and Belorussian teams and gamers in all international esports events and cancel all international events holding [sic] on the territory of Russia and Belarus."

These moves, Fedorov suggests, "will motivate the citizens of Russia to proactively stop the disgraceful military aggression" by the Russian government. "In 2022, modern technology is perhaps the best answer to the tanks, multiple rocket launchers... and missiles." In an additional note directed at the Xbox and PlayStation Twitter accounts, Fedorov wrote that "if you support human values, you should [leave] the Russian market!" In a follow-up tweet, Fedorov also asked Riot Games, EA, Ubisoft, Gameloft, and Wargaming to "close your office in Russia" in solidarity with Ukraine. "There's no place for [an] aggressor on the global technological map!"

The Russian invasion of Ukraine has been marked both by brutality and stunningly modern turns -- from threats to crash the International Space Station and chaotic cyber vigilantism to the ambiguous role that cryptocurrency is playing on both sides of the war. Now, Ukraine has taken a page out of the buzzy crypto industry playbook and announced an "airdrop" to "reward" those who donated to the country's defense efforts using cryptocurrency in a tweet more in line with a startup than a nation at war, to the elation of some and the confusion of many. From a report: "Airdrop confirmed," the official Twitter account for Ukraine's government tweeted on Wednesday morning in a thread where it listed cryptocurrency donation addresses. "Snapshot will be taken tomorrow, on March 3rd, at 6pm Kyiv time (UTC/GMT +2 hours). Reward to follow!"

David Boggs, an electrical engineer and computer scientist who helped create Ethernet, the computer networking technology that connects PCs to printers, other devices and the internet in offices and homes, died on Feb. 19 in Palo Alto, Calif. He was 71. From a report: His wife, Marcia Bush, said his death, at Stanford Hospital, was caused by heart failure. In the spring of 1973, just after enrolling as a graduate student at Stanford University, Mr. Boggs began an internship at Xerox PARC, a Silicon Valley research lab that was developing a new kind of personal computer. One afternoon, in the basement of the lab, he noticed another researcher tinkering with a long strand of cable.

The researcher, another new hire named Bob Metcalfe, was exploring ways of sending information to and from the lab's new computer, the Alto. Mr. Metcalfe was trying to send electrical pulses down the cable, and he was struggling to make it work. So Mr. Boggs offered to help. Over the next two years, they designed the first version of Ethernet. "He was the perfect partner for me," Mr. Metcalfe said in an interview. "I was more of a concept artist, and he was a build-the-hardware-in-the-back-room engineer." Many of the key technologies that would be developed over the next two decades as part of the Alto project would come to define the modern computer, including the mouse, the graphical user interface, the word processor and the laser printer, as well as Ethernet.

"We all know Linux is written in C," writes ZDNet. "What you may not know is that it's written in a long-outdated C dialect: The 1989 version of the C language standard, C89."

But that's about to change, explains long-time Slashdot reader UnknowingFool: Linus Torvalds has decided that Linux will move to the C11 standard starting with kernel 5.18.... Linux had planned to move to a newer standard eventually with C99 being the next version. However a recent patch to a security problem revealed that there could be problems with C99.

In order to patch a potential security problem with Linux's linked-list primitive speculative-execution functions, it was found that C99 would require the iterator must be declared outside the loop which would expose it to another security problem. Since C99 was not very popular, it was agreed to skip it and use C11. Backwards compatibility with most compilers like gcc should allow for an easily transition of most of the code.
ZDNet adds that "This isn't as big a transition as it may seem. C89 still has almost universal support. Because any C compiler is backward compatible with earlier versions, you won't have any trouble compiling or running a C89 program. So, a C11 compliant compiler won't have any trouble with any C89 legacy code."

Scientists have unveiled the largest human family tree ever created, a shared ancestry that is woven out of more than 3,600 individual genome sequences that date back more than 100,000 years, providing an unprecedented glimpse into the deep past and complex present of our species. Motherboard reports: The immense family tree was stitched together from existing datasets and contains modern genetic information from around the world as well as samples from extinct human relatives such as Neanderthals and Denisovans. Scientists led by Anthony Wilder Wohns, who conducted the research while earning a PhD at the University of Oxford's Big Data Institute, were able to confirm major events in human history from this integrated framework, such our species' migration out of Africa, while also encountering surprises about past populations that will require more research to understand. The outcome is a "unified genealogy of modern and ancient humans" that demonstrates the power of computational methods "to recover relationships between individuals and populations as well as to identify descendants of ancient samples," according to a study published on Thursday in Science. Though this particular study is focused on humans, the team noted that the same approach could be used for almost any other species.

One of the innovations of study is a new algorithm that can more efficiently collate all this information into a single genealogy or tree sequence. By revealing relationships between individuals and populations of humans that stretch back deep into our prehistory, the approach mapped out 231 million ancestral lineages of our human family over time, as shown in the [video here]. The findings confirmed the timing of many migrations that are known from archaeological evidence, but there were a few unexpected implications in the data as well. For instance, the new family tree hints that humans first arrived in North America 56,000 years ago, much earlier than is currently estimated, and points to human migration to Papua New Guinea a full 100,000 years before the earliest documented evidence of habitation in that region. These tantalizing results do not necessarily mean that those migration timelines should be pushed back, but they do offer a compelling avenue of research going forward.

Having an asteroid slam into Earth was catastrophic for the dinosaurs, but the season of the strike may have substantially ramped up extinction rates for others species, research suggests. From a report: Scientists have found evidence that the devastating impact 66m years ago, which wiped out three-quarters of Earth's species and created the Chicxulub crater in modern-day Mexico, happened in the spring in the northern hemisphere. The timing means that many animals north of the equator would have been particularly vulnerable to the intense heatwave unleashed by the collision, having just emerged from the harsh months of winter. Other animals in the south may have fared better given that it was autumn, especially if they were hunkering down in burrows. The direct hit from the asteroid triggered an extreme global heatwave that proved lethal for many exposed animals. In the aftermath, temperatures are thought to have plummeted in a nuclear winter that drove many more species to extinction.

A recent post on the AWS Open Source blog announced that AWS "is investing in the sustainability of Rust, a language we believe should be used to build sustainable and secure solutions."

It was written by the chair of the Rust foundation (and leader of AWS's Rust team) with a Principal Engineer at AWS, and reminds us that Rust "combines the performance and resource efficiency of systems programming languages like C with the memory safety of languages like Java."

But there's another reason they're promoting Rust: Worldwide, data centers consume about 200 terawatt hours per year. That's roughly 1% of all energy consumed on our planet... [C]loud and hyperscale data centers have been implementing huge energy efficiency improvements, and the migration to that cloud infrastructure has been keeping the total energy use of data centers in balance despite massive growth in storage and compute for more than a decade... [I]s the status quo good enough? Is keeping data center energy use to 1% of worldwide energy consumption adequate..? [Will] innovations in energy efficiency continue to keep pace with growth in storage and compute in the future? Given the explosion we know is coming in autonomous drones, delivery robots, and vehicles, and the incredible amount of data consumption, processing, and machine learning training and inference required to support those technologies, it seems unlikely that energy efficiency innovations will be able to keep pace with demand...

[J]ust like security, sustainability is a shared responsibility. AWS customers are responsible for energy efficient choices in storage policies, software design, and compute utilization, while AWS owns efficiencies in hardware, utilization features, and cooling systems.... In the same way that operational excellence, security, and reliability have been principles of traditional software design, sustainability must be a principle in modern software design. That's why AWS announced a sixth pillar for sustainability to the AWS Well-Architected Framework. What that looks like in practice is choices like relaxing service-level agreements for non-critical functions and prioritizing resource use efficiency. We can take advantage of virtualization and allow for longer device upgrade cycles. We can leverage caching and longer times-to-live whenever possible. We can classify our data and implement automated lifecycle policies that delete data as soon as possible. When we choose algorithms for cryptography and compression, we can include efficiency in our decision criteria.

Last, but not least, we can choose to implement our software in energy efficient programming languages.

There was a really interesting study a few years ago that looked at the correlation between energy consumption, performance, and memory use.... What the study did is implement 10 benchmark problems in 27 different programming languages and measure execution time, energy consumption, and peak memory use. C and Rust significantly outperformed other languages in energy efficiency. In fact, they were roughly 50% more efficient than Java and 98% more efficient than Python. It's not a surprise that C and Rust are more efficient than other languages. What is shocking is the magnitude of the difference. Broad adoption of C and Rust could reduce energy consumption of compute by 50% — even with a conservative estimate....

No one developer, service, or corporation can deliver substantial impact on sustainability. Adoption of Rust is like recycling; it only has impact if we all participate. To achieve broad adoption, we are going to have to grow the developer community.
That "interesting study" cited also found that both C and Rust execute faster than other programming languages, the blog post points out, so "when you choose to implement your software in Rust for the sustainability and security benefits, you also get the optimized performance of C."

And the post also notes Linus Torvalds' recent acknowledgement that while he really loves C, it can be like juggling chainsaws, with easily-overlooked and "not always logical" type interactions. (Torvalds then went on to call Rust "the first language I saw which looked like this might actually be a solution.")
