Ground teams on Florida's Space Coast hoisted Boeing's Starliner spacecraft atop its United Launch Alliance Atlas V rocket this week, putting all the pieces in place for liftoff next month with two veteran NASA astronauts on a test flight to the International Space Station.

This will be the first time astronauts fly on Boeing's Starliner crew capsule, following two test flights without crew members in 2019 and 2022. The Starliner Crew Flight Test (CFT) next month will wrap up a decade and a half of development and, if all goes well, will pave the way for operational Starliner missions to ferry crews to and from the space station.

Starliner is running years behind schedule and over budget. SpaceX's Crew Dragon spacecraft has flown all of NASA's crew rotation missions to the station since its first astronaut flight in 2020. But NASA wants to get Boeing's spacecraft up and running to have a backup to SpaceX. It would then alternate between Starliner and Crew Dragon for six-month expeditions to the station beginning next year.

Anybody can contribute to the Linux kernel, but any person's commit suggestion can become the focus of the kernel's master and namesake, Linus Torvalds. Torvalds is famously not overly committed to niceness, though he has been working on it since 2018. You can see glimpses of this newer, less curse-laden approach in how Torvalds recently addressed a commit with which he vehemently disagreed. It involves tabs.

The commit last week changed exactly one thing on one line, replacing a tab character with a space: "It helps Kconfig parsers to read file without error." Torvalds responded with a commit of his own, as spotted by The Register, which would "add some hidden tabs on purpose." Trying to smooth over a tabs-versus-spaces matter seemed to awaken Torvalds to the need to have tab-detecting failures be "more obvious." Torvalds would have added more, he wrote, but didn't "want to make things uglier than necessary. But it *might* be necessary if it turns out we see more of this kind of silly tooling."

If you've read this far and don't understand what's happening, please allow me, a failed CS minor, to offer a quick explanation: Tabs Versus Spaces will never be truly resolved, codified, or set right by standards, and the energy spent on the issue over time could, if harnessed, likely power one or more small nations. Still, the Linux kernel has its own coding style, and it directly cites "K&R," or Kernighan & Ritchie, the authors of the coding bible The C Programming Language, which is a tabs book. If you are submitting kernel code, it had better use tabs (eight-character tabs, ideally, though that is tied in part to teletype and line-printer history).

Over the weekend, developer Mattia La Spina launched iGBA as one of the first retro game emulators legitimately available on the iOS App Store following Apple's rules change regarding such emulators earlier this month. As of Monday morning, though, iGBA has been pulled from the App Store following controversy over the unauthorized reuse of source code from a different emulator project.

Shortly after iGBA's launch, some people on social media began noticing that the project appeared to be based on the code for GBA4iOS, a nearly decade-old emulator that developer Riley Testut and a partner developed as high-schoolers (and distributed via a temporary security hole in the iOS App Store). Testut took to social media Sunday morning to call iGBA a "knock-off" of GBA4iOS. "I did not give anyone permission to do this, yet it’s now sitting at the top of the charts (despite being filled with ads + tracking)," he wrote.

GBA4iOS is an open source program released under the GNU GPLv2 license, with licensing terms that let anyone "use, modify, and distribute my original code for this project without fear of legal consequences." But those expansive licensing terms only apply "unless you plan to submit your app to Apple’s App Store, in which case written permission from me is explicitly required."

There is the mental image that most people have of electronics recycling, and then there is the reality, which is shredding.

Less than 20 percent of e-waste even makes it to recycling. That which does is, if not acquired through IT asset disposition (ITAD) or spotted by a worker who sees some value, heads into the shredder for raw metals extraction. If you've ever toured an electronics recycling facility, you can see for yourself how much of your stuff eventually gets chewed into little bits, whether due to design, to unprofitable reuse markets, or sheer volume concerns.

Traditional hard drives have some valuable things inside them—case, cover, circuit boards, drive assemblies, actuators, and rare-earth magnets—but only if they avoid the gnashing teeth. That's where the DiskMantler comes in. Garner Products, a data elimination firm, has a machine that it claims can process 500 hard drives (the HDD kind) per day in a way that leaves a drive separated into those useful components. And the DiskMantler does this by shaking the thing to death (video).

For the first time, SpaceX will launch one of its reusable Falcon 9 boosters for a 20th time Friday night on a flight to deliver 23 more Starlink Internet satellites to orbit.

This milestone mission is scheduled to lift off at 9:22 pm EDT Friday (01:22 UTC Saturday) from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station, Florida. Forecasters from the US Space Force predict "excellent" weather for the primetime launch.

Falcon 9 will blaze a familiar trail into space, following the same profile as dozens of past Starlink missions.

Sketchy cosmetic injections of what seem to be counterfeit Botox are behind a multistate outbreak of botulism-like illnesses, state health officials report.

So far, at least six people have fallen ill in two states: four in Tennessee and two in Illinois. Four of the six people required hospitalization for their condition (two in Tennessee and both cases in Illinois).

The Centers for Disease Control and Prevention is reportedly planning a nationwide alert to notify clinicians of the potentially counterfeit Botox and advise them to be on the lookout for botulism-like illnesses. The agency did not immediately respond to Ars' request for information.

Amylyx, the maker of a new drug to treat ALS, is pulling that drug from the market and laying off 70 percent of its workers after a large clinical trial found that the drug did not help patients, according to an announcement from the company Thursday.

The drug, Relyvrio, won approval from the Food and Drug Administration in September 2022 to slow the progression of ALS (amyotrophic lateral sclerosis, or Lou Gehrig's disease). However, the data behind the controversial decision was shaky at best; it was based on a study of just 137 patients that had several weaknesses and questionable statistical significance, and FDA advisors initially voted against approval. Still, given the severity of the neurogenerative disease and lack of effective treatments, the FDA ultimately granted approval under the condition that the company was working on a Phase III clinical trial to solidify its claimed benefits.

Relyvrio—a combination of two existing, generic drugs—went on the market with a list price of $158,000.

Schleswig-Holstein, one of Germany’s 16 states, on Wednesday confirmed plans to move tens of thousands of systems from Microsoft Windows to Linux. The announcement follows previously established plans to migrate the state government off Microsoft Office in favor of open source LibreOffice.

As spotted by The Document Foundation, the government has apparently finished its pilot run of LibreOffice and is now announcing plans to expand to more open source offerings.

In 2021, the state government announced plans to move 25,000 computers to LibreOffice by 2026. At the time, Schleswig-Holstein said it had already been testing LibreOffice for two years.

If you run a personal or hobby website, getting a copyright notice from a law firm about an image on your site can trigger some fast-acting panic. As someone who has paid to settle a news service-licensing issue before, I can empathize with anybody who wants to make this kind of thing go away.

Which is why a new kind of angle-on-an-angle scheme can seem both obvious to spot and likely effective. Ernie Smith, the prolific, ever-curious writer behind the newsletter Tedium, received a "DMCA Copyright Infringement Notice" in late March from "Commonwealth Legal," representing the "Intellectual Property division" of Tech4Gods.

The issue was with a photo of a keyfob from legitimate photo service Unsplash used in service of a post about a strange Uber ride Smith once took. As Smith detailed in a Mastodon thread, the purported firm needed him to "add a credit to our client immediately" through a link to Tech4Gods, and said it should be "addressed in the next five business days." Removing the image "does not conclude the matter," and should Smith not have taken action, the putative firm would have to "activate" its case, relying on DMCA 512(c) (which, in many readings, actually does grant relief should a website owner, unaware of infringing material, "act expeditiously to remove" said material). The email unhelpfully points to the main page of the Internet Archive so that Smith might review "past usage records."

X has named a new head of safety about nine months after Ella Irwin resigned last June, following Elon Musk's criticism of Irwin's team's decision to restrict a transphobic documentary. Shortly after Irwin left, former head of brand safety AJ Brown similarly resigned. And that regime notably took over where former safety chief Yoel Roth—who also clashed with Musk—left off.

Stepping into the safety chief role next is Kylie McRoberts, who was promoted after leading X "initiatives to increase transparency in our moderation practices through labels" and "improve security with passkeys," X's announcement said.

As head of safety, McRoberts will oversee X's global safety team, which was rebranded last month to drop "trust" from its name. On X, Musk had said that "any organization that puts ‘Trust’ in their name cannot [be] trusted, as that is obviously a euphemism for censorship."

The George Carlin estate has settled its lawsuit with Dudesy, the podcast that purportedly used a "comedy AI" to produce an hour-long stand-up special in the style and voice of the late comedian.

Dudesy's "George Carlin: Dead and Loving It" special, which was first uploaded in early January, gained hundreds of thousands of views and plenty of media attention for its presentation as a creation of an AI that had "listened to all of George Carlin’s material... to imitate his voice, cadence and attitude as well as the subject matter I think would have interested him today." But even before the Carlin estate lawsuit was filed, there were numerous signs that the special was not actually written by an AI, as Ars laid out in detail in a feature report.

Shortly after the Carlin estate filed its lawsuit against Dudesy in late January, a representative for Dudesy host Will Sasso told The New York Times that the special had actually been "completely written by [Dudesy co-host] Chad Kultgen."

Ever since Elon Musk's X Corp sued Media Matters for America (MMFA) over a pair of reports that X (formerly Twitter) claims caused an advertiser exodus in 2023, one big question has remained for onlookers: Why is this fight happening in Texas?

In a motion to dismiss filed in Texas' northern district last month, MMFA argued that X's lawsuit should be dismissed not just because of a "fatal jurisdictional defect," but "dismissal is also required for lack of venue."

Notably, MMFA is based in Washington, DC, while "X is organized under Nevada law and maintains its principal place of business in San Francisco, California, where its own terms of service require users of its platform to litigate any disputes."

Before the cancellation of The Problem with Jon Stewart on Apple TV+, Apple forbade the inclusion of Federal Trade Commission Chair Lina Khan as a guest and steered the show away from confronting issues related to artificial intelligence, according to Jon Stewart.

This isn't the first we've heard of this rift between Apple and Stewart. When the Apple TV+ show was canceled last October, reports circulated that he told his staff that creative differences over guests and topics were a factor in the decision.

The New York Times reported that both China and AI were sticking points between Apple and Stewart. Stewart confirmed the broad strokes of that narrative in a CBS Morning Show interview after it was announced that he would return to The Daily Show.

I recently tried to use a Raspberry Pi 5 as a regular desktop PC. The experiment wasn't a failure—I was able to use a Pi to get most of my work done for a few days. But the device's performance, and especially the relative immaturity of the Linux's Arm software ecosystem, meant that there were lots of incompatibilities and rough edges.

One of the problems with trying to use a Pi 5 as a regular desktop computer is that, by the time you've paid for the 8GB version of the board, a decent active cooler and case, and (ideally) some kind of M.2 storage attachment and SSD, you've spent close to a couple of hundred dollars on the system. That's not a ton of money to spend on a desktop PC, but it is enough that the Pi no longer feels miraculously cheap, and there are actually other, more flexible competitors worth considering.

Consider the selection of sub-$200 mini desktop PCs that litter the online storefronts of Amazon and AliExpress. Though you do need to roll the dice on low-to-no-name brands like Beelink, GMKTec, Firebat, BMax, Trigkey, or Bosgame, it's actually possible to buy a reasonably capable desktop system with 8GB to 16GB of RAM, 256GB or 512GB of storage, a Windows 11 license, and a workaday x86-based Intel CPU for as little as $107, though Amazon pricing usually runs closer to $170.

On Friday, a lone Microsoft developer rocked the world when he revealed a backdoor had been intentionally planted in xz Utils, an open source data compression utility available on almost all installations of Linux and other Unix-like operating systems. The person or people behind this project likely spent years on it. They were likely very close to seeing the backdoor update merged into Debian and Red Hat, the two biggest distributions of Linux, when an eagle-eyed software developer spotted something fishy.

"This might be the best executed supply chain attack we've seen described in the open, and it's a nightmare scenario: malicious, competent, authorized upstream in a widely used library," software and cryptography engineer Filippo Valsorda said of the effort, which came frightfully close to succeeding.

Researchers have spent the weekend gathering clues. Here's what we know so far.

Enlarge / Internet Backdoor in a string of binary code in a shape of an eye. (credit: Getty Images)

Researchers have found a malicious backdoor in a compression tool that made its way into widely used Linux distributions, including those from Red Hat and Debian.

The compression utility, known as xz Utils, introduced the malicious code in versions ​​5.6.0 and 5.6.1, according to Andres Freund, the developer who discovered it. There are no known reports of those versions being incorporated into any production releases for major Linux distributions, but both Red Hat and Debian reported that recently published beta releases used at least one of the backdoored versions—specifically, in Fedora Rawhide and Debian testing, unstable and experimental distributions. A stable release of Arch Linux is also affected. That distribution, however, isn't used in production systems.

Because the backdoor was discovered before the malicious versions of xz Utils were added to production versions of Linux, “it's not really affecting anyone in the real world,” Will Dormann, a senior vulnerability analyst at security firm Analygence, said in an online interview. “BUT that's only because it was discovered early due to bad actor sloppiness. Had it not been discovered, it would have been catastrophic to the world.”

Two lawsuits filed by a civil rights group allege that county jails in Michigan banned in-person visits in order to maximize revenue from voice and video calls as part of a "quid pro quo kickback scheme" with prison phone companies.

Civil Rights Corps filed the lawsuits on March 15 against the county governments, two county sheriffs, and two prison phone companies. The suits filed in county courts seek class-action status on behalf of people unable to visit family members detained in the local jails, including children who have been unable to visit their parents.

Defendants in one lawsuit include St. Clair County Sheriff Mat King, prison phone company Securus Technologies, and Securus owner Platinum Equity. In the other lawsuit, defendants include Genesee County Sheriff Christopher Swanson and prison phone company ViaPath Technologies. ViaPath was formerly called Global Tel*Link Corporation (GTL), and the lawsuit primarily refers to the company as GTL.

I enjoy getting my exercise but hate doing it indoors. I'd much rather get some fresh air and watch the world drift past me as I cycle or hike somewhere than watch a screen while sweating away on something stationary.

To get a bit more of what I like, I've invested in a variety of gear that has extended my cycling season deeper into the winter. But even with that, there are various conditions—near-freezing temperatures, heavy rains, Canada catching fire—that have kept me off the roads. So, a backup exercise plan has always been on my to-do list.

The company LifeSpan offers exercise equipment that fits well into a home office and gave me the chance to try its Ampera model. It's a stationary bike that tucks nicely under a standing desk and has a distinct twist: You can pedal to power the laptop you're working on. Overall, the hardware is well-designed, but some glitches, software issues, and design decisions keep it from living up to its potential.

Starlink's mobile ambitions were dealt at least a temporary blow yesterday when the Federal Communications Commission dismissed SpaceX's application to use several spectrum bands for mobile service.

SpaceX is seeking approval to use up to 7,500 second-generation Starlink satellites with spectrum in the 1.6 GHz, 2 GHz, and 2.4 GHz bands. SpaceX could still end up getting what it wants but will have to go through new rulemaking processes in which the FCC will evaluate whether the spectrum bands can handle the system without affecting existing users.

The FCC Space Bureau's ruling dismissed the SpaceX application yesterday as "unacceptable for filing." The application was filed over a year ago.

Unsealed court documents have revealed more details about a secret Facebook project initially called "Ghostbusters," designed to sneakily access encrypted Snapchat usage data to give Facebook a leg up on its rival, just when Snapchat was experiencing rapid growth in 2016.

The documents were filed in a class-action lawsuit from consumers and advertisers, accusing Meta of anticompetitive behavior that blocks rivals from competing in the social media ads market.

"Whenever someone asks a question about Snapchat, the answer is usually that because their traffic is encrypted, we have no analytics about them," Facebook CEO Mark Zuckerberg (who has since rebranded his company as Meta) wrote in a 2016 email to Javier Olivan.

This week, Florida made headlines after passing HB 3, a law banning children under 14 from accessing social media without parental consent.

Much less attention was given to another requirement under the law obligating "pornographic or sexually explicit websites" to "use age verification to prevent minors from accessing sites that are inappropriate for children," as Republican Florida Governor Ron DeSantis explained the law in a statement.

But Pornhub's parent company, Aylo, has taken notice, with a spokesperson confirming to Ars that "we are aware of the passage into law of HB 3 in Florida, which unfortunately fails to protect minors online."

Under the very unassuming name of patch 1.1.0f1, Cities: Skylines 2 is getting something quite big. The sequel now has the modding, map editing, and code modding support that made its predecessor such a sprawling success.

Only time will tell if community energy can help restore some of the momentum that has been dispersed by the fraught launch of Cities: Skylines 2 (C:S2). The project of relatively small developer Colossal Order arrived in October 2023 with performance issues and a lack of content compared to its predecessor. Some of that content perception stemmed from the game's lack of modding support, which had contributed to entire aspects of the original game not yet available in the sequel.

When Ars interviewed Colossal Order CEO Mariina Hallikainen in December, she said that modding support was the thing she was most looking forward to arriving. Modding support was intended to be available at launch, but the challenges of building the new game's technical base, amid many other technical issues, pushed it back, along with console releases.

On Monday, Florida became the first state to ban kids under 14 from social media without parental permission. It appears likely that the law—considered one of the most restrictive in the US—will face significant legal challenges, however, before taking effect on January 1.

Under HB 3, apps like Instagram, Snapchat, or TikTok would need to verify the ages of users, then delete any accounts for users under 14 when parental consent is not granted. Companies that "knowingly or recklessly" fail to block underage users risk fines of up to $10,000 in damages to anyone suing on behalf of child users. They could also be liable for up to $50,000 per violation in civil penalties.

In a statement, Florida governor Ron DeSantis said the "landmark law" gives "parents a greater ability to protect their children" from a variety of social media harm. Florida House Speaker Paul Renner, who spearheaded the law, explained some of that harm, saying that passing HB 3 was critical because "the Internet has become a dark alley for our children where predators target them and dangerous social media leads to higher rates of depression, self-harm, and even suicide."

HOUSTON—While it doesn't have the same relevance to public consciousness as safety problems with commercial airliners, a successful test flight of Boeing's Starliner spacecraft in May would be welcome news for the beleaguered aerospace company.

This will be the first time the Starliner capsule flies into low-Earth orbit with humans aboard. NASA astronauts Butch Wilmore and Suni Williams are in the final stages of training for the so-called Crew Flight Test (CFT), a milestone running seven years behind the schedule Boeing said it could achieve when it won a $4.2 billion commercial crew contract from NASA a decade ago.

If schedules hold, Wilmore and Williams will take off inside Boeing's Starliner spacecraft aboard a United Launch Alliance Atlas V rocket after midnight May 1, local time, from Cape Canaveral Space Force Station in Florida. They will fly Starliner to the International Space Station for a stay of at least eight days, then return the capsule to a parachute-assisted, airbag-cushioned landing in the western United States, likely at White Sands, New Mexico.

Flying on commercial airlines today might be a lot more of a pain than it used to be, but new tech is going to bring some improvement to one part of the experience—in-flight entertainment. Panasonic Avionics' brand Astrova in-flight entertainment systems are starting to roll out on commercial flights on certain airlines, promising 4K HDR TVs and other features to the backs of seats that should be a huge upgrade over the abysmal screens we normally watch in-flight movies on.

Look at most commercial airlines today, and you'll find a tiny, terrible LCD TV embedded in the seat in front of you. These HD, standard dynamic range screens have terrible contrast and poor viewing angles, and they aren't bright enough to achieve a good viewing experience when the overhead lights are on.

They're bad enough that I always bring my own hardware for flights—most recently, I took three flights with Apple's Vision Pro headset, which I plan to write about later this week. But most people just bring a tablet.

Mozilla's Monitor Plus, a service launched by the privacy-minded tech firm in February, notes on its pitch page that there is "a $240 billion industry of data brokers selling your private information for profit" and that its offering can "take back your privacy."

Mozilla's most recent move to protect privacy has been to cut out one of the key providers of Monitor Plus' people-search protections, Onerep. That comes after reporting from security reporter Brian Krebs, who uncovered Onerep CEO and founder Dimitri Shelest as the founder of "dozens of people-search services since 2010," including one, Nuwber, that still sells the very kind of "background reports" that Monitor Plus seeks to curb.

Shelest told Krebs in a statement (PDF) that he did have an ownership stake in Nuwber, but that Nuwber has "zero cross-over or information-sharing with Onerep" and that he no longer operates any other people-search sites. Shelest admitted the bad look but said that his experience with people search gave Onerep "the best tech and team in the space."

It probably hasn't escaped notice that electric vehicles, having captured everyone's attention, are having a bit of a slide into what Gartner calls "the trough of depression." But as skeptics push back on battery EVs, another style of electrified car looks set to travel back up the slope of enlightenment. Plug-in hybrids are finding their second wind, as automakers and regulators look to PHEVs as a way to reduce transport-related carbon emissions.

Lincoln's Corsair Grand Touring is not a particularly new PHEV, but since we hadn't tested one yet and there was an example on the local press fleet, it seemed prudent to schedule a week with this compact crossover from one of America's luxury brands.

The first thing to note is that, despite the way it might look in photos, this is not a huge land barge. The Corsair is 181.4 inches (4,608 mm) long, 76.4 inches (1,941 mm) wide, and 64.1 inches (1,628 mm) tall, so about the same size as a Toyota RAV4, or six inches shorter than a Tesla Model Y. The shape uses plenty of curved edges, dominated by the large Lincoln grille up front, with a hint of late-teens Audi SUV to it.

Have you ever worked on a hobby project where modifying and compiling the source code for a Linux-based emulator was possibly the easiest and most straightforward part of the whole thing?

Kevin Noki really, really wanted a functioning Macintosh Plus, complete with a functioning, auto-ejecting disk drive that it could boot from. The German maker already had a Mac Plus (1Mb) from eBay, but it had both a busted power supply and floppy drive. Rather than carve out the busted Plus' one-of-a-kind internals and slap a Raspberry Pi in there like some DIY slacker, Noki went… a different path.

Noki 3D-printed his own Macintosh, the "Brewintosh." I would like you to consider what you think that last sentence means and then wipe your expectations clean. I have watched the entire 48-minute journey of Noki's Brewintosh, which is both very soothing on some ASMR-adjacent gut level and also low-key maddening for the way it plays down all the individual accomplishments along the way. Any one of the Brewintosh's pieces would be my entire weekend, and my spouse would not enjoy my mood while I was sunk into it.

Glassdoor, where employees go to leave anonymous reviews of employers, has recently begun adding real names to user profiles without users' consent, a Glassdoor user named Monica was shocked to discover last week.

"Time to delete your Glassdoor account and data," Monica, a Midwest-based software professional, warned other Glassdoor users in a blog. (Ars will only refer to Monica by her first name so that she can speak freely about her experience using Glassdoor to review employers.)

Monica joined Glassdoor about 10 years ago, she said, leaving a few reviews for her employers, taking advantage of other employees' reviews when considering new opportunities, and hoping to help others survey their job options. This month, though, she abruptly deleted her account after she contacted Glassdoor support to request help removing information from her account. She never expected that instead of removing information, Glassdoor's support team would take the real name that she provided in her support email and add it to her Glassdoor profile—despite Monica repeatedly and explicitly not consenting to Glassdoor storing her real name.

Meta is considering cutting monthly subscription fees for Facebook and Instagram users in the European Union nearly in half to comply with the Digital Market Act (DMA), Reuters reported.

During a day-long public workshop on Meta's DMA compliance, Meta's competition and regulatory director, Tim Lamb, told the European Commission (EC) that individual subscriber fees could be slashed from 9.99 euros to 5.99 euros. Meta is hoping that reducing fees will help to speed up the EC's process for resolving Meta's compliance issues. If Meta's offer is accepted, any additional accounts would then cost 4 euros instead of 6 euros.

Lamb said that these prices are "by far the lowest end of the range that any reasonable person should be paying for services of these quality," calling it a "serious offer."

The Steam Deck's OS is purpose-built for handheld gaming, but it's confined to one device, unless you're willing to head out to the bleeding edge. Beyond SteamOS, there is Windows, which can let down ambitious Deck-likes, there is the Nintendo Switch, and there are Android-based devices that are a lot like Android phones. This setup has got at least one company saying, in infomercial tones, that there has got to be a better way.

That company is Playtron, a new software startup that aims to fix that setup with a Linux-based gaming OS that's tied to no particular game store or platform. Playtron has $10 million, coders from open source projects like ChimeraOS and Heroic Games Launcher, and the former CEO of Cyanogen. With that, it aims to have "Playtron-native devices shipping worldwide in 2025," and to capture the 1 billion "core casual" gamers they see as under-served.

What devices will Playtron use to serve them? Some of them might be Steam Decks, as you will "soon be able to install Playtron on your favorite handheld PC," according to Playtron's ambitious, somewhat scattershot single-page website. Some might be "Playtron-powered 5G devices coming soon to markets around the world." Really, though, Playtron aims to provide a gaming platform to any device with a CPU and a screen, be it desktop or mobile, ARM or x86, TV or car.

Human brains (and the brains of other vertebrates) are able to process information faster because of myelin, a fatty substance that forms a protective sheath over the axons of our nerve cells and speeds up their impulses. How did our neurons evolve myelin sheaths? Part of the answer—which was unknown until now—almost sounds like science fiction.

Led by scientists from Altos Labs-Cambridge Institute of Science, a team of researchers has uncovered a bit of the gnarly past of how myelin ended up covering vertebrate neurons: a molecular parasite has been messing with our genes. Sequences derived from an ancient virus help regulate a gene that encodes a component of myelin, helping explain why vertebrates have an edge when it comes to their brains.

Prehistoric infection

Myelin is a fatty material produced by oligodendrocyte cells in the central nervous system and Schwann cells in the peripheral nervous system. Its insulating properties allow neurons to zap impulses to one another at faster speeds and greater lengths. Our brains can be complex in part because myelin enables longer, narrower axons, which means more nerves can be stacked together.

PALM SPRINGS, Calif.—Lincoln is one of those car companies that for years will give the impression that the people in charge are asleep at the proverbial wheel and then all of a sudden will debut a total knockout. It’s happened a few times throughout the brand’s long history, most recently with the fourth-generation Navigator. The introduction of the 2018 Navigator also sparked a huge overhaul in design and technology for the brand that catapulted it from “decent free rental car upgrade” to a maker of luxury SUVs that people might want to buy. The 2024 Lincoln Nautilus is just such an SUV.

In the hierarchy of Lincoln models, the Nautilus sits neatly between the Aviator and the smaller Corsair. It’s arguably one of the best looking of the current crop of Lincolns, and it’s positioned to compete with the likes of the Lexus RX, the Cadillac XT6 and Volvo’s XC60, among others. But does it actually compete? Or is it simply another car for the Enterprises and Hertzes of the world?

The 2024 Nautilus is available in two flavors: a purely internal combustion-powered version with a 250 hp (186 kW) turbocharged inline-four that also puts out 280 lb-ft (380 Nm) of torque and is paired with an eight-speed automatic transmission; and a much more interesting hybrid version, which offers up 310 combined hp (231 kW) that's paired with a CVT transmission. The Nautilus is only available with all-wheel drive.

About 50 people were injured on a LATAM Airlines flight today in which a Boeing 787-9 Dreamliner suffered a technical problem that caused a "strong shake," reportedly causing some passengers' heads to hit the ceiling.

The plane flying from Australia to New Zealand "experienced a strong shake during flight, the cause of which is currently under investigation," LATAM said on its website today. LATAM, a Chilean airline, was also quoted in news reports as saying the plane suffered "a technical event during the flight which caused a strong movement."

The Boeing plane, carrying 263 passengers and nine flight and cabin crew members, landed at Auckland Airport as scheduled. New Zealand ambulance service Hato Hone St. John published a statement saying that its "ambulance crews assessed and treated approximately 50 patients, with one patient in a serious condition and the remainder in a moderate to minor condition." Twelve patients were taken to hospitals, the statement said.

Democratic lawmakers are probing SpaceX over Russia's reported use of Starlink in Ukraine, saying that recent developments raise questions about SpaceX's "compliance with US sanctions and export controls."

SpaceX CEO Elon Musk last month denied what he called "false news reports [that] claim that SpaceX is selling Starlink terminals to Russia," saying that, "to the best of our knowledge, no Starlinks have been sold directly or indirectly to Russia." But Musk's statement didn't satisfy US Reps. Jamie Raskin (D-Md.) and Robert Garcia (D-Calif.), who sent a letter to SpaceX President Gwynne Shotwell yesterday.

"Starlink is an invaluable resource for Ukrainians in their fight against Russia's brutal and illegitimate invasion. It is alarming that Russia may be obtaining and using your technology to coordinate attacks against Ukrainian troops in illegally occupied regions in Eastern and Southern Ukraine, potentially in violation of US sanctions and export controls," Raskin and Garcia wrote.

On Wednesday, authorities arrested former Google software engineer Linwei Ding in Newark, California, on charges of stealing AI trade secrets from the company. The US Department of Justice alleges that Ding, a Chinese national, committed the theft while secretly working with two China-based companies.

According to the indictment, Ding, who was hired by Google in 2019 and had access to confidential information about the company's data centers, began uploading hundreds of files into a personal Google Cloud account two years ago.

The trade secrets Ding allegedly copied contained "detailed information about the architecture and functionality of GPU and TPU chips and systems, the software that allows the chips to communicate and execute tasks, and the software that orchestrates thousands of chips into a supercomputer capable of executing at the cutting edge of machine learning and AI technology," according to the indictment.

On Monday, Anthropic prompt engineer Alex Albert caused a small stir in the AI community when he tweeted about a scenario related to Claude 3 Opus, the largest version of a new large language model launched on Monday. Albert shared a story from internal testing of Opus where the model seemingly demonstrated a type of "metacognition" or self-awareness during a "needle-in-the-haystack" evaluation, leading to both curiosity and skepticism online.

Metacognition in AI refers to the ability of an AI model to monitor or regulate its own internal processes. It's similar to a form of self-awareness, but calling it that is usually seen as too anthropomorphizing, since there is no "self" in this case. Machine-learning experts do not think that current AI models possess a form of self-awareness like humans. Instead, the models produce humanlike output, and that sometimes triggers a perception of self-awareness that seems to imply a deeper form of intelligence behind the curtain.

In the now-viral tweet, Albert described a test to measure Claude's recall ability. It's a relatively standard test in large language model (LLM) testing that involves inserting a target sentence (the "needle") into a large block of text or documents (the "haystack") and asking if the AI model can find the needle. Researchers do this test to see if the large language model can accurately pull information from a very large processing memory (called a context window), which in this case is about 200,000 tokens (fragments of words).

Linux reached 4.03 percent of global market share in February, according to data from research firm Statcounter. That takes Linux past the 3 percent milestone it reached in June 2023. While we’re still far from the Year of the Linux Desktop, interest in Linux has somewhat grown lately.

Statcounter says it gets its desktop operating system (OS) usage stats from tracking code installed on over 1.5 million global websites generating over 5 billion monthly page views. The only adjustments the firm says it makes to this data are around removing bot activity and adjusting for Google Chrome prerendering. Note that when Statcounter analyzes desktop OSes, it also includes laptop computers, and Statcounter says it may revise its data within 45 days of publication.

As spotted by Linuxiac, Linux’s reported desktop market share was higher than ever in February. If you count ChromeOS as a Linux OS, then market share totaled 6.34 percent in February, although that number is actually smaller than what Statcounter reported in June: 2 percent.

Amid safety scandals involving "many loose bolts" and widespread problems with Boeing's 737 Max 9s, Boeing is apparently considering buying back Spirit AeroSystems, the key supplier behind some of Boeing's current manufacturing problems, sources told The Wall Street Journal.

Spirit was initially spun out from Boeing Commercial Airplanes in 2005, and Boeing had planned to keep it that way. Last year, Boeing CEO Dave Calhoun sought to dispel rumors that Boeing might reacquire Spirit as federal regulators launched investigations into both companies. But now Calhoun appears to be "softening that stance," the WSJ reported.

According to the WSJ's sources, no deal has formed yet, but Spirit has initiated talks with Boeing and "hired bankers to explore strategic options." Sources also confirmed that Spirit is weighing whether to sell its operations in Ireland, which manufactures parts for Boeing rival Airbus.

It looks like Elon Musk may lose X's lawsuit against hate speech researchers who encouraged a major brand boycott after flagging ads appearing next to extremist content on X, the social media site formerly known as Twitter.

X is trying to argue that the Center for Countering Digital Hate (CCDH) violated the site's terms of service and illegally accessed non-public data to conduct its reporting, allegedly posing a security risk for X. The boycott, X alleged, cost the company tens of millions of dollars by spooking advertisers, while X contends that the CCDH's reporting is misleading and ads are rarely served on extremist content.

But at a hearing Thursday, US district judge Charles Breyer told the CCDH that he would consider dismissing X's lawsuit, repeatedly appearing to mock X's decision to file it in the first place.

Any Linux user trying to send the highest-resolution images to a display at the fastest frame rate is out of luck for the foreseeable future, at least when it comes to an HDMI connection.

The licensing group that controls the HDMI standard, the HDMI Forum, has reportedly told AMD that it does not allow an open source implementation of the HDMI 2.1 (or HDMI 2.1+) specification, blocking tools such as AMD's FreeSync from working over HDMI connections at resolution/rate combinations like 4K at 120 Hz, or 5K at 240 Hz.

Linux blog Phoronix noted in January 2021 that the HDMI Forum did not offer public access to the HDMI 2.1 specification. Alex Deucher, an AMD engineer who has long contributed to the company's open source offerings, has kept a related bug thread alive for at least two years, only to deliver the negative outcome yesterday.

One of the most interesting developments in 3D gaming in the last half-decade or so is the advent of advanced upscaling technologies—features like Nvidia's Deep-Learning Super Sampling (DLSS), AMD's FidelityFX Super Resolution (FSR), and Intel's Xe Super Sampling (XeSS). These technologies all aim to provide better, sharper image quality when playing at non-native resolutions, and when they're working well, they can boost frame rates and help squeeze a bit more life out of an older or lower-end GPU.

The problem has been that it's incumbent on developers to support each individual upscaling technology in each of their games, and that not all graphics hardware supports the same upscaling capabilities. DLSS usually looks a bit better than FSR, but it requires an Nvidia GPU; FSR works on just about anything but doesn't look quite as good. (Intel's XeSS exists somewhere in the middle, in that it works with any modern GPU but looks best when it can leverage Intel's GPU hardware.)

Microsoft is stepping in to try to straighten up this muddle of conceptually similar, executionally different technologies with a new API called DirectSR (the SR is for Super Resolution). The new API was announced in a blog post about Microsoft's 2024 Game Developers Conference sessions, and it was developed by Microsoft "in partnership with GPU hardware vendors."

When a severe winter storm hit Oregon on January 13, Nicholas Brown's CenturyLink fiber Internet service stopped working at his house in Portland.

The initial outage was understandable amid the widespread damage caused by the storm, but CenturyLink's response was poor. It took about 39 days for CenturyLink to restore broadband service to Brown and even longer to restore service to one of his neighbors. Those reconnections only happened after Ars Technica contacted the telco firm on the customers' behalf last week.

Brown had never experienced any lengthy outage in over four years of subscribing to CenturyLink, so he figured the telco firm would restore his broadband connection within a reasonable amount of time. "It had practically never gone down at all up to this point. I've been quite happy with it," he said.

We've heard this before, but Boeing appears to be a couple of months from finally launching astronauts into orbit aboard the commercial CST-100 Starliner crew capsule.

It was about two months prior to this mission's previous launch date last July when Boeing and NASA officials decided to put a hold on launch preparations. During their final reviews to certify Starliner for flight nearly a year ago, engineers discovered two technical issues that somehow escaped detection for years.

One of these issues involved parts of Starliner's parachute deployment system that did not meet required safety specifications. The other was a revelation that Boeing installed flammable tape wrapped around wiring bundles throughout the spacecraft, creating a potential fire hazard. These were the latest in a line of technical problems that have plagued the Starliner program, delaying the new spacecraft's first test flight with astronauts from 2017 until this year.

In the early 20th century, the deadliest nutrient-related disease in US history ravaged the American South. Pellagra, a disease caused by a deficiency in niacin and/or tryptophan, is marked by the four "D's": diarrhea, dermatitis that leads to gruesome skin plaques, dementia, and death. At its peak during the Great Depression, pellagra killed nearly 7,000 Southerners a year. Between 1906 and 1940, researchers estimate that the epidemic struck roughly 3 million Americans, killing around 100,000.

The deadly epidemic led to voluntary—and eventually mandatory—fortification of wheat and other cereals with niacin (aka Vitamin B3). By the middle of the century, pellagra nearly vanished from the US. But, decades later, the public health triumph may be backfiring. With Americans' diets more reliant than ever on processed, niacin-fortified foods, the average niacin intake in the US is now nearing what's considered the tolerable upper limit of the nutrient, according to a federal health survey. And an extensive study recently published in Nature Medicine suggests that those excess amounts of niacin may be exacerbating cardiovascular disease, increasing risks of heart attacks, strokes, and death.

The study, led by Stanley Hazen, chair of Cardiovascular and Metabolic Sciences at Cleveland Clinic's Lerner Research Institute, connected high blood levels of a breakdown product of niacin—and to a lesser extent, tryptophan—to an elevated risk of major adverse cardiovascular events (MACE). And this elevated risk appears to be independent of known risk factors for those events, such as high cholesterol.

Welcome to Edition 6.32 of the Rocket Report! I'm writing the report again this week as Eric Berger is in Washington, DC, to receive a well-earned honor, the 2024 Excellence in Commercial Space Journalism Award from the Commercial Spaceflight Federation. Cape Canaveral is the world's busiest spaceport, and this week, three leading US launch companies were active there. SpaceX launched another Falcon 9 rocket, and a few miles away, Blue Origin raised a New Glenn rocket on its launch pad for long-awaited ground testing. Nearby, United Launch Alliance began assembling an Atlas V rocket for the first crew launch of Boeing's Starliner spacecraft in April. 2024 is shaping up to be a truly exciting year for the spaceflight community.

As always, we welcome reader submissions, and if you don't want to miss an issue, please subscribe using the box below (the form will not appear on AMP-enabled versions of the site). Each report will include information on small-, medium-, and heavy-lift rockets, as well as a quick look ahead at the next three launches on the calendar.

This new spacecraft, delivered into orbit on February 18 by Rocket Lab, will approach a defunct upper stage from a Japanese H-IIA rocket that has been circling Earth for more than 15 years. Over the next few months, the satellite will try to move within arm's reach of the rocket, taking pictures and performing complicated maneuvers to move around the bus-size H-IIA upper stage as it moves around the planet at nearly 5 miles per second (7.6 km/s).

A judge has dismissed a complaint from a parent and guardian of a girl, now 15, who was sexually assaulted when she was 12 years old after Snapchat recommended that she connect with convicted sex offenders.

According to the court filing, the abuse that the girl, C.O., experienced on Snapchat happened soon after she signed up for the app in 2019. Through its "Quick Add" feature, Snapchat "directed her" to connect with "a registered sex offender using the profile name JASONMORGAN5660." After a little more than a week on the app, C.O. was bombarded with inappropriate images and subjected to sextortion and threats before the adult user pressured her to meet up, then raped her. Cops arrested the adult user the next day, resulting in his incarceration, but his Snapchat account remained active for three years despite reports of harassment, the complaint alleged.

Two years later, at 14, C.O. connected with another convicted sex offender on Snapchat, a former police officer who offered to give C.O. a ride to school and then sexually assaulted her. The second offender is also currently incarcerated, the judge's opinion noted.

British comedian Michael McIntyre has a standard bit in his standup routines concerning the many (many!) slang terms posh British people use to describe being drunk. These include "wellied," "trousered," and "ratarsed," to name a few. McIntyre's bit rests on his assertion that pretty much any English word can be modified into a so-called "drunkonym," bolstered by a few handy examples: "I was utterly gazeboed," or "I am going to get totally and utterly carparked."

It's a clever riff that sparked the interest of two German linguists. Christina Sanchez-Stockhammer of Chemnitz University of Technology and Peter Uhrig of FAU Erlangen-Nuremberg decided to draw on their expertise to test McIntyre's claim that any word in the English language could be modified to mean "being in a state of high inebriation." Given their prevalence, "It is highly surprising that drunkonyms are still under-researched from a linguistic perspective," the authors wrote in their new paper published in the Yearbook of the German Cognitive Linguistics Association. Bonus: the authors included an extensive appendix of 546 English synonyms for "drunk," drawn from various sources, which makes for entertaining reading.

There is a long tradition of coming up with colorful expressions for drunkenness in the English language, with the Oxford English Dictionary listing a usage as early as 1382: "merry," meaning "boisterous or cheerful due to alcohol; slight drunk, tipsy." Another OED entry from 1630 lists "blinde" (as in blind drunk) as a drunkonym. Even Benjamin Franklin got into the act with his 1737 Drinker's Dictionary, listing 288 words and phrases for denoting drunkenness. By 1975, there were more than 353 synonyms for "drunk" listed in that year's edition of the Dictionary of American Slang. By 1981, linguist Harry Levine noted 900 terms used as drunkonyms.

Neuralink co-founder Elon Musk said the first human to be implanted with the company's brain chip is now able to move a mouse cursor just by thinking.

"Progress is good, and the patient seems to have made a full recovery, with no ill effects that we are aware of. Patient is able to move a mouse around the screen by just thinking," Musk said Monday during an X Spaces event, according to Reuters.

Musk's update came a few weeks after he announced that Neuralink implanted a chip into the human. The previous update was also made on X, the Musk-owned social network formerly named Twitter.

Famed naturalist Charles Darwin amassed an impressive personal library over the course of his life, much of which was preserved and cataloged upon his death in 1882. But many other items were lost, including more ephemeral items like unbound volumes, pamphlets, journals, clippings, and so forth, often only vaguely referenced in Darwin's own records.

For the last 18 years, the Darwin Online project has painstakingly scoured all manner of archival records to reassemble a complete catalog of Darwin's personal library virtually. The project released its complete 300-page online catalog—consisting of 7,400 titles across 13,000 volumes, with links to electronic copies of the works—to mark Darwin's 215th birthday on February 12.

“This unprecedentedly detailed view of Darwin’s complete library allows one to appreciate more than ever that he was not an isolated figure working alone but an expert of his time building on the sophisticated science and studies and other knowledge of thousands of people," project leader John van Wyhe of the National University of Singapore said. "Indeed, the size and range of works in the library makes manifest the extraordinary extent of Darwin’s research into the work of others.”
