An anonymous reader quotes a report from Ars Technica: Reddit will start requiring people to be logged into Reddit to use old.reddit.com. The new requirement will take effect "over the next month," a Reddit employee going by the username boat-botany announced on the social media platform today. The person claimed that the change is part of an ongoing effort to "tighten how automated systems access Reddit."

The Reddit employee wrote: "Old Reddit's logged-out experience is a significant source of abusive scraping and automated traffic on the platform. It's also an important interface for many long-time mods and Redditors. To strike the right balance between preserving your access to Old Reddit while preventing abusive scraping and automated traffic, over the next month we will start requiring everyone to log in."

In a follow-up comment, boat-botany defined abusive behavior as that which violates Reddit's rule prohibiting activity that interferes with the platform's "normal use" or that "create[s] programs or applications" that break Reddit's (controversial) API rules. "By logging in, we get a lot more signal that allows us to detect whether an account is breaking the rules, and then we can block that traffic or enforce those accounts," boat-botany said. Asked why boat-botany scrapes New Reddit less frequently than Old Reddit, the Reddit employee pointed to another commenter's explanation. "[T]he shape of malicious traffic is always changing," the user, Nestramutat, wrote. "It's going to be a constant cat and mouse game[.] As you ban one method, a new one gets developed. It's easy to see abusive traffic in hindsight, but it's harder to pre-emptively block it. Given that they're claiming Old Reddit doesn't have the modern security stack, this is likely proving to be an even greater challenge."

Nestramutat said that the login requirement will add a barrier against threat actors. "You're also now attaching an account ID to every malicious request, plus account creation is only available on New Reddit (with the enhanced security stack)."

As for how long Old Reddit will exist, boat-botany left the door open for its retirement. "We can't promise it will be around forever, but [Reddit CEO Steve Huffman] himself has said we'll keep supporting it while folks are still using it," boat-botany wrote. "That said, it doesn't have the same modern security tech stack reddit.com has, so we need to tighten security on old reddit to keep it viable."

A federal judge rejected Meta's bid to dismiss claims from 29 state attorneys general alleging that Facebook and Instagram were designed to addict children while concealing the harms. The judge found significant factual disputes that must be decided at trial. They also ruled that Meta failed to comply with federal parental notice and consent requirements for children under 13, "and granted summary judgement to the states on that issue," reports Reuters. From the report: In a separate statement, California Attorney General Rob Bonta called the decision a "critical win" in holding Meta accountable for fueling a mental health crisis among American children. Gonzalez Rogers also oversees related multidistrict litigation by more than 2,600 individuals, school districts and local governments over whether social media platforms such as Facebook, Instagram, Google and YouTube, Snapchat and TikTok addict children.

The states said research has shown that children's use of Facebook and Instagram could lead to depression, anxiety, insomnia, interference with education and daily life, and self-harm including suicide. Meta countered that the attorneys general had no evidence it misled consumers about its platforms' alleged addictiveness, including in congressional testimony by Chief Executive Mark Zuckerberg. The Menlo Park, California-based company said this was because "social media addiction" is not an established psychiatric condition, and therefore statements that its platforms are not addictive could not be false. Meta also said it didn't violate the children's online privacy law because it directed Facebook and Instagram to a general audience, not just children under age 13.

In a 38-page decision, Gonzalez Rogers found material factual disputes over whether Meta's social media platforms are addictive, whether Meta falsely denied it designed them that way, and whether it "partially" directed the platforms at children. "The AGs present a reasonable interpretation of [Meta's] statements that Facebook and Instagram are not designed in ways that cause teens to compulsively use the platforms to their detriment," the judge wrote. "To the extent plaintiffs' evidence shows that the platforms are in fact designed to do just that, a jury could reasonably find the statements were untrue to a reasonable person," she added. A trial over California, Colorado, Kentucky and New Jersey's claims against Meta is scheduled for August 18, court records show.

The FAA plans to replace its 1973 ban on civilian supersonic flight over U.S. land with a noise-based standard, potentially allowing aircraft to exceed Mach 1 as long as they stay below certain sound limits. The agency aims to finalize the rules by mid-2027, opening the door for companies such as Boom Supersonic and Spike Aerospace to operate quieter next-generation passenger jets over land. Longtime Slashdot reader schwit1 shared the notice (PDF) published Tuesday by the FAA. Forbes reports: Technological advances "will eliminate the old sonic boom," FAA Administrator Bryan Bedford said in a statement. "This means we can ultimately repeal the ban from the 1970s on supersonic flight over U.S. territory while minimizing noise impacts to residents in communities along the route and near airports." The primary reason was public opposition to loud sonic booms. In the 1960s, a plane flying faster than the speed of sound -- about 660 mph at high altitudes -- created shock waves that traveled to the ground and reached human ears as a loud gunshot-like crack or thunder-like boom. Tests during that decade, including the Oklahoma City sonic boom experiments, found repeated booms broke windows, damaged property and generated thousands of public complaints.

In its 1973 ruling, the FAA stated that due to the limits of technology at that time, "a prohibition was needed to protect the public from sonic boom .... by preventing operations of a civil aircraft at a true flight Mach number greater than 1." Several years later, Air France and British Airways introduced Concorde, and were allowed to serve New York's John F. Kennedy International Airport as long as flights remained subsonic over U.S. land. Notably, "the prestigious London-New York service was the only truly profitable [Concorde] route, supported by high-powered business and celebrity travel," wrote a former British Airways network planner for Forbes in 2021.

Several U.S. companies are working on a new generation of luxurious supersonic passenger aircraft with much quieter sonic booms and improved fuel efficiency. In particular, Colorado-headquartered Boom Supersonic says it has pre-orders from United Airlines, American Airlines and Japan Airlines for its Overture jets, which will carry 60-80 passengers. Atlanta-based Spike Aerospace is developing smaller Diplomat jets for up to 18 passengers. Both companies' websites tout future transatlantic flights in under four hours.

Google has shut down the Tenor API, breaking GIF pickers in services that still relied on it and forcing platforms such as X to migrate elsewhere. 9to5Google notes that the library itself remains available at Tenor.com and "integrations within Google products are also still active, including Gboard, Google Messages, and more." From the report: The Tenor API has been rejecting new API sign-ups in January of this year, but existing integrations remained in place. This week, though, they're shutting down, and any integrations that remain in place will stop working on July 1. The support page adds details that "any API or Ads Distribution Agreements" with Tenor will be terminated on June 30, while "current integrations" will be "fully decommissioned" as of June 30.

One of the most notable examples here is Twitter/X, which has relied on Tenor for its GIF picker for years. Twitter/X Head of Product Nikita Bier confirmed that the platform has migrated elsewhere, which is why the "recently used" section was purged, and why you might notice fewer GIF options when posting. Other platforms affected include Discord, WhatsApp, and Bluesky.

Microsoft has released a public preview of Windows Subsystem for Linux (WSL) containers, adding a built-in command-line tool and API for running Linux containers directly inside Windows applications without third-party software. The update also introduces faster file access, improved networking and memory management, plus integration with Defender, Intune, and VS Code. The Register reports: WSL has always been a handy way to run Linux workloads from Windows, and is particularly convenient for Linux developers who must comply with corporate edicts to use a Windows device. The CLI for end-to-end container workflows furthers this. Microsoft stated, "WSL containers make it easier for developers and organizations to build, test, and run containerized workloads while benefiting from the security, manageability, and integration of the Windows platform."

Alternatively, you could run your preferred Linux distribution natively, but that might not be an option, particularly if an organization is keen on the "security, manageability, and integration of the Windows platform." And this is an important point. WSL's existing Microsoft Defender for Endpoint (MDE) has been updated (in private preview) to be aware of Linux container events, and there are settings in Intune for managing WSL containers. Support is also in a pre-release version of VS Code, where the Docker path in the dev container settings can be changed to wslc.

There is also a new default file system for WSL container that Microsoft claims makes Windows file access twice the speed. So, going from terribly slow to just slow? We'll wait until general availability is reached before passing judgment. There's a new default networking mode to improve compatibility and better memory reclaim techniques. However, none of these tweaks will be enabled by default in WSL. Microsoft wrote, "Since these changes touch mission critical paths like file system access and network, for now they are enabled just in WSL container."

Ford executives said they've hired 350 veteran engineers — some of them former employees — after AI and automated systems failed to deliver the desired quality, reports TechCrunch: Bloomberg reports the company's chief operating officer Kumar Galhotra told journalists that Ford had been "relying more and more on automated quality systems" with disappointing results. So the company "brought back technical specialists," and those specialists "hunt for failure points before a part ever reaches the plant floor."

Charles Poon, Ford's vice president of vehicle hardware engineering, added, "Mistakenly we thought that by just introducing artificial intelligence and ingesting the design requirements that we had, that that would produce a high-quality product."
The article points out that Ford is using the rehired gray beard engineers to train younger staff — and, to reprogram its AI tools.

"South Korea plans to train every single member of its nearly half-million-strong military to operate drones as easily as they handle personal firearms," reports Ars Technica: The goal is to make drones a "universal combat tool" for all troops by training them to use drones like a "second personal weapon," said Ahn Gyu-back, South Korea's Minister of National Defense, in a June 26 briefing reported by Reuters and other media outlets. The announcement coincides with broader plans to equip individual military units with more cheap and expendable drones for surveillance and strike missions, along with deploying more counter-drone lasers and microwave weapons.

Meanwhile, South Korea's former drone operations command headquarters that used to have direct command authority over combat units will be reorganized to focus on collaborating with South Korean industry on developing and procuring commercial drone technology, according to The Korea Times. The South Korean defense minister specifically cited the conflicts in Ukraine and the Middle East as inspiring such military reforms with a focus on drone technologies... Ukraine's use of drones and military robots as a force multiplier to offset its numerical disadvantage on the battlefield versus Russia's larger military may carry special resonance for South Korea, given that the South Korean military's current active-duty strength of 450,000 personnel faces a numerical disadvantage against North Korea's active-duty military consisting of more than 1.2 million soldiers...

The defense ministry is starting out by providing 11,000 "training drones" to military personnel this year, with the goal of eventually deploying 60,000 drones across the military by 2029. An additional complication comes from the South Korean military looking to procure drones with 100 percent domestically produced components and no Chinese components due to security concerns, according to the defense minister's comments reported by Reuters... South Korean companies are building new military attack drones, but the defense ministry may struggle to find enough commercial drones made without Chinese components to train hundreds of thousands of military conscripts, said Min-Cheol Jung, a cofounder of the Team Retriever counter-drone red team based in South Korea, in a War on the Rocks article.

The Los Angeles Police Department says about 1,500 police agencies across America have drone programs, reports SFGate, and 58 of those drone-using police agencies are in California.

The Sacramento County sheriff's office recently posted drone footage on Instagram set to theme from "Mission: Impossible," claiming "a nationwide first" where their drone successfully disarmed a felon "seen earlier with a firearm" (though now not moving, but holding a knife while lying face down in a garage). In the video the "not responding" suspect continues not moving as the drone dangles a magnet which catches on the knife. The drone then pulls multiple times until it comes out of the unmoving suspect's hand. The sheriff's office says their footage shows their drone "disarm an armed suspect, helping bring the incident to a safe resolution," in their post on Instagram, "rather than rush into a potentially deadly encounter..." Was he pretending to be dead or simply lying in wait for deputies to approach...?

It's also worth noting that our drones are labeled as "military equipment" (even though anyone can purchase them at their local Walmart), but are really just another piece of technology helping deputies resolve dangerous situations safely. Their use protects both law enforcement personnel and suspects.
SFGate offers more reports from around California: In Yucaipa, officials launched a Drone as First Responder (DFR) pilot program on May 28, the San Bernardino County Sheriff's Department announced this month. According to the release, drones have already been used to respond to over 100 calls for service, arriving before deputies for 71% of them. "The drones also contributed to 12 arrests, assisted in locating persons of interest on 37 occasions, and provided aerial overwatch during 44 incidents," it continues, though details on how they assisted the police are unclear. The drones, manufactured by Skydio, were also used to locate a young person experiencing a mental health crisis and another person launching illegal fireworks.

Microsoft has quietly extended free Windows 10 security updates for consumers by another year, pushing the Extended Security Updates (ESU) program's end date from October 12, 2026, to October 12, 2027. "The ESU support page was updated with that date, and Microsoft's blog post on the program has a new editor's note confirming the change," reports Ars Technica. From the report: The prevalence of Windows across so many devices and form factors has given Microsoft a massive customer base for decades, but it has also stymied the company's efforts to roll out new operating systems. Microsoft famously extended the support window for Windows XP numerous times throughout the 2010s as it became apparent that millions of PCs would never be updated. Windows 10 isn't quite as entrenched as XP was, but it has still been a slog getting people to upgrade to Windows 11 even nearly five years after release.

Unlike many past Windows updates, Windows 11 required some users to buy new PCs with specific CPU technologies and a Trusted Platform Module (TPM). Microsoft was widely criticized for excluding perfectly serviceable PCs, and that's turning into a problem in 2026. The AI-driven shortage of storage and memory has made system upgrades vastly more expensive, potentially slowing upgrades. Some have also avoided Windows 11 due to Microsoft's intense focus on AI features.

The result is that Windows 10 remains stubbornly popular. According to StatCounter data, Windows 10 is still running on about 26 percent of PCs, while Windows 11 sits at 72 percent. That means there are still hundreds of millions of active Windows 10 installs, but those machines will be up to date for at least an additional year.

schwit1 shares a report from The Wall Street Journal: The European Union Aviation Safety Agency has ordered (PDF) urgent inspections of 16 Airbus A380 planes operated by Emirates and Qantas, after cracks were found in a wing component on some aircraft (source paywalled; alternative source).. Cracks were found during earlier inspections of the wing spars structure, a key component of the wing, EASA said in a directive effective Wednesday. EASA determined that they "could reduce the structural integrity of the wing."

"To address this potential unsafe condition, Airbus determined that an additional special detailed inspection has to be accomplished," EASA said. The first group of five aircraft, operated by Emirates, need to be inspected immediately, while the second group of 11 aircraft can be inspected later but within 25 flight cycles, EASA said in a separate statement. From the second group, 10 are operated by Emirates and one by Qantas, the aviation safety agency said.

Longtime Slashdot reader schwit1 shares a report from autoevolution: The U.S. Department of Commerce's Bureau of Industry and Security denied Polestar an authorization under the Connected Vehicle Rule. Polestar will continue to sell its existing inventory of Polestar 3 and 4 crossovers in the United States and will continue to offer support to customers and access to its service network. But no new 2027 models will set wheels on American soil.

The Connected Vehicle Rule is a regulation that restricts the import and sale of vehicles equipped with Vehicle Connectivity Systems (VCS) and Automated Driving Systems (ADS) tied to foreign adversaries, primarily from China and Russia. Polestar is owned by Chinese auto giant Geely, which has also been the parent company of Swedish brand Volvo since 2010. However, Volvo has recently been granted authorization to sell connected vehicles in the United States.

The rule, set out by the Bureau of Industry and Security (BIS), classifies modern vehicles as mobile data centers and is designed to protect national security by keeping sensitive driver data and vehicle control systems out of the hands of foreign governments. Michael Lohscheller, Polestar CEO, confirms that the company is well aware that the automotive industry is entering a new phase, based on regional dynamics. So, Polestar will shift its strategy to its biggest market as it is preparing its exit from the U.S. market. The report notes that Polestar sold 5,384 cars in the U.S. in 2025, with 60,119 units sold globally.

Apple has sharply raised prices across its Mac, iPad, HomePod, and Apple TV lineups as surging AI-driven demand creates a global memory and storage shortage. Increases range from $30 for the HomePod mini to $1,300 for the M3 Ultra Mac Studio, with Apple CEO Tim Cook saying efforts to shield customers from higher costs had become "unsustainable." The Verge reports: On Thursday, the company adjusted the price of its new MacBook Neo, which will now start at $699 instead of $599, while the base MacBook Air will jump to $1,299 from $1,099, as reported earlier by Bloomberg. The 14-inch MacBook Pro is getting an increase as well, going from $1,699 to $1,999. Meanwhile, the iPad Air will now start at $749 instead of $599, while the iPad Pro is increasing to $1,199 from $999.

As spotted by MacRumors, the M4 Max Mac Studio will now cost $2,499, a big jump from $1,999. The M3 Ultra Mac Studio is now priced at $5,299, up from $3,999. Apple is even raising the prices of its HomePod, which now costs $349 instead of $299, as well as bumping the price of the HomePod mini to $129 instead of $99. The Apple TV also now costs $199 instead of $129.

Micron has signed 16 "strategic customer agreements" (SCAs) that include a floor price the company says comes with "a very robust gross margin for Micron, well above our peak quarterly margins in any past cycle." Most of the deals run through 2030 and cover about 40% of Micron's revenue. The Register reports: Micron CEO, president and chairman Sanjay Mehrotra explained the SCAs in prepared remarks delivered during the company's Q3 earnings call. He explained that Micron has signed 16 SCAs, most of them covering 2026 to 2030, and that they involve a commitment to buy a certain quantity of product and pay for it in a pricing band that has a floor and a ceiling price. The floor price covers the historically high gross margins mentioned above, and the ceiling price means those who commit to an SCA are insulated if memory prices go even higher.

The CEO said 16 customers have signed SCAs and then explained why it's worth locking into the deals even though they bake in such high margins. "Our customers are recognizing that supply shortages in memory and storage will take considerable time to improve," he said. "Even as we expect industry supply to improve gradually in 2028, we currently do not have line of sight as to when memory supply will be able to catch up with increasing demand."

Even massive efforts to build new chip fabs aren't much help, he said, because the increasing complexity of new memory types means it takes longer to build factories -- and when they come online there still won't be enough capacity to build both the high-bandwidth memory needed for AI and other types of NAND and DRAM. "Supply is structurally constrained in its growth and ability to meet industry demand, despite our comprehensive efforts to increase supply," he said.

Don't assume that SCAs mean your suppliers get price certainty, because Mehrotra said the deals will account for 40 percent of Micron revenue -- meaning the company is reserving most of its inventory to sell at prices it can negotiate. The CEO did have a little good news in the form of predictions that Micron's DRAM output in 2026 will "grow in the low- to mid-20s percentage range, slightly above our prior outlook." He also revealed that the SCAs see customers pay up front, which helps Micron to fund its fab expansions.

An anonymous reader quotes a report from Ars Technica: Google spent the last few years locked in a legal grudge match with Epic Games, which claimed that Google's stewardship of the Play Store was anticompetitive. Now, the companies are thick as thieves, and Google is beginning to implement app store changes as agreed in its settlement with Epic. The lower developer fees and new payment options that Google promised are rolling out in select markets this month before expanding. [...] Starting on June 30, developers in Europe, the UK, and the US will have access to the new fee structure. This system will split the commission into two components: billing and service fees.

The biggest win for small developers is the new flat 10 percent service fee for the first $1 million in earnings every year. Above that, the rate for various transaction types may reach 25 percent on existing installs. Apps installed after June 30 will top out at 20 percent. Developers will finally be allowed to send users outside the Play Store to complete a transaction, too. Google says they can design a choice screen "in accordance with our UX guidelines" to direct users to these external options. Devs pay the standard service fee on these purchases, but they'll avoid the billing fee. All transactions that run through Google's Play Store platform add a 5 percent billing fee -- even the base rate for publishers earning less than $1 million. Google notes that the billing fee is set at 5 percent in the initial markets, but it could be different in other regions. Google will expand the new fee structure globally through September 2027, while also offering reduced fees through updated developer programs.

Although the changes may let developers retain more revenue, Google will continue controlling Android distribution and collecting a share of sales as it works toward allowing certified third-party app stores to operate more like the Play Store.

joshuark shares a report from Car and Driver: A new study conducted by the New York Times shows that the increase in vehicle hood height seen over the last two and a half decades, mainly due to the rise in popularity of large SUVs and trucks, has resulted in several thousand deaths that otherwise may not have happened. The study shows that while automakers and regulators have focused on occupant safety, they have turned a blind eye to pedestrian safety, which has fallen since around 2009. Researchers looked at four main datasets in their investigation: crash test data from the National Highway Traffic Safety Administration's (NHTSA) Crash Report Sampling System (CRSS) from 2016 to 2024; NHTSA's Fatality Analysis Reporting System (FARS); vehicle measurement data from Expert AutoStats; and vehicle registration data from S&P Global from 2002 to 2024. The researchers concluded that the increased danger to pedestrians is caused by two main culprits.

First, large SUVs and trucks have taller hoods, raising the point of impact above most people's center of gravity and pushing them to the ground, typically hard asphalt, rather than up and onto the hood, which is designed to absorb impacts. Second, with larger A-pillars designed to protect occupants in rollover crashes, modern cars tend to have larger blind spots than cars sold at the turn of the century (presuming the 21st century). The shift toward vehicles with taller hoods led to roughly 3000 deaths between 2016 and 2024. This number is conservative because it does not include crashes that take place in parking lots, driveways, or private roads, which aren't part of the federal database.

The data also showed an estimated 2.8 percent increase in the odds of a pedestrian fatality for every one-inch increase in vehicle hood height. Between two different scenarios, one decreasing the hood height of every vehicle in the dataset by 3 inches, and the second using a random sampling of hood heights from 2002 across 10,000 simulated crashes, between 2624 (for scenario two) and 3077 (for scenario one) lives could have been saved from 2016 to 2024.

Slate Auto says its stripped-down electric pickup will start at $24,950 before fees, with the base model's estimated range increased from 150 to about 205 miles. The company has started taking preorders on Wednesday. "The aggressive pricing -- half the average cost of a new car in the United States -- puts Slate in position to capture a share of the lowest end of the new car market, which has few gas and fewer electric options these days," reports TechCrunch. From the report: The price reveal comes more than a year after Slate Auto emerged from stealth. Since then, the company has been steadily detailing the extremely basic, transforming EV, which starts as a two-seater pickup truck, but can be modified into a five-seater SUV. The SUV version will start at $29,950, Slate said Wednesday. Slate has said the conversion can be done by professionals or by owners themselves. On Wednesday, it finally showed off some of the first of its "Slate University" how-to videos, which guide people through the steps for doing everything from the SUV conversion to adding headlight covers.

Everything else about the truck is bare, though it's customizable. It has hand-crank windows, lacks an infotainment system, and all orders start with the same gray composite material, with no paint options, as Slate plans to let buyers order customizable wraps for the vehicle. That likely helps cut out a major cost center, as factory paint shops can run in the hundreds of millions of dollars. The company did not offer more details about the buying process. Slate has said it "won't have traditional dealerships," and plans to sell directly to customers, similar to other EV companies like Tesla, Rivian, and Lucid Motors.

Meta has paused its Model Compatibility Initiative that tracked employee mouse movements, clicks, keystrokes, and screen content to train AI agents, after some of its collected data became accessible to more employees than intended. Meta says it has no evidence the information was improperly accessed and will not restart the program until it is confident in its safeguards. Wired reports: Meta rolled out the Model Compatibility Initiative (MCI) tool in April to US employees. The tool "collects computer inputs such as mouse movements, click locations and keystrokes, as well as screen content," according to workers who have been petitioning against it over privacy, security, and personal liberty concerns. When MCI launched, employees couldn't opt out, but that changed to a limited degree after workers protested. Meta executives have repeatedly defended the data-gathering project, saying it was necessary to train AI systems to operate computer software the way humans do and that employees were the best examples for the artificial intelligence to learn from.

On Monday, a Meta engineer issued an internal security notice stating that databases filled with information gathered by MCI had been exposed to anyone inside the company. A former employee actively involved in pushing back against MCI describes the lapse as "a mess" -- and one that employees had expected would occur. "When workers raised concerns, leadership doubled down and failed to acknowledge the risks workers raised about the safety and privacy of worker and customer data," the person says. "Leadership has clearly created an authoritarian environment where workers are no longer respected or heard."

But after critical comments poured into internal forums on Monday expressing frustration about the security issue, Meta shocked some of its staff by pausing MCI altogether, telling WIRED about the development several hours before announcing it to employees. A few workers told WIRED they were confused in the meantime because the tool was continuing to run on their laptops. Late on Monday, Stephane Kasriel, a Meta vice president overseeing AI research, announced the pause and told staff that the security issue had been discovered on June 18 and addressed within four hours. But the initial fix didn't stick and access to the data had to be further locked down. The issue made "some MCI-derived data" accessible to more people than intended, he wrote, without elaborating.

A peer-reviewed Nature critique argues that Microsoft's 2025 Majorana quantum-computing breakthrough -- and its claim that it could enable "a truly meaningful quantum computer not in decades, as some have predicted, but in years" -- is fundamentally flawed. According to Dr Henry Legg, a lecturer at the University of St Andrews, the claims were undermined by omitted data, selective plotting, and basic Python errors that concealed alternative results. Microsoft, for its part, says the bugs were minor and stands by its findings and roadmap. The Register reports: "Last year they claimed to be years, not decades from a 'topological quantum supercomputer,'" Legg told The Register in an email. "My feeling is that they are centuries, not decades away. If it works at all -- and, based on what I have seen, the most likely scenario is that it doesn't work." Based on his analysis of the research Microsoft published in 2025, Legg argues that the company's claims about finding and being able to control the elusive Majorana particle to build a topological superconductor do not withstand scrutiny.

"I demonstrate that Microsoft's tune-up software is flawed and that coding errors resulted in incorrect statements to peer reviewers," said Legg. "Raw data, which was omitted from the original paper, also appears to indicate Microsoft's devices contain considerable disorder and are not compatible with the existence of a topological gap. In other words, the prerequisites for Microsoft's claims do not appear to be met, but this was obscured because this data did not appear in the original publication."

Essentially, Microsoft has proposed a Topological Gap Protocol (TGP) that can be used to detect the phase transition deemed to be a prerequisite for conducting quantum calculations using Majorana particles. Legg argues that based on his analysis of underlying transport data (measurements of particle change) -- omitted from the original publication -- Microsoft chose to focus on results that supported its thesis and ignored data that could be interpreted as a negative result. As he notes in his critique: "The TGP plotting code was set to highlight only the largest purportedly topological region."

"The primary consequence was the omission of other regions that passed their tune-up protocol (the TGP)," said Legg. "When peer reviewers asked if other regions existed, Microsoft inaccurately stated that they had investigated the only region passing the protocol within the explored range. This was not correct." Legg also argues that Microsoft mishandled its code. "The code antisymmetrized bias voltage based on array index rather than physical value," his analysis says.

In other words, Microsoft's researchers made a basic programming mistake by evaluating the array index -- the number identifying a value's position in an array -- instead of the value to which the index refers. "There were two pretty basic Python programming errors that hid these alternative regions," Legg explained. "Their plotting software was hardcoded with a filter (zbp_cluster_numbers=[1]) that forced it to display only the single largest region, concealing other successful results from their phase maps. Changing this to zbp_cluster_numbers=[1,2] shows already a second region." Legg added: "The TGP software transformed the data by simply reversing a Python array (x[::-1]) based on its index position, ignoring the actual physical bias voltages."

Longtime Slashdot reader hackingbear shares a report from TOP500: The 67th edition of the TOP500 list of the world's most powerful supercomputers was announced today at the ISC 2026 conference in Hamburg, Germany. LineShine, a previously unlisted system installed in China, debuts at No. 1, displacing El Capitan as the world's most powerful supercomputer as measured by the High Performance Linpack (HPL) benchmark. LineShine achieved 2.198 Exaflop/s on HPL -- about 80 percent of its 2.736 Exaflop/s theoretical peak -- making it the first system on the TOP500 to exceed two exaflops of sustained double-precision performance using CPUs only.

Installed at the National Supercomputing Centre in Shenzhen (NSCS) and built by the Shenzhen Cloud Computing Center, the system is based on a custom Chinese processor and the "LingKun" platform: 13.79 million cores across 304-core LX2 processors running at 1.55 GHz, linked by the proprietary LingQi interconnect and running Kylin OS. LineShine draws approximately 42.2 megawatts of power, for an efficiency of 52.07 Gigaflops/Watt. Its debut marks the first time since 2017 that a Chinese system has led the TOP500, and it also takes over the No. 1 position on the HPCG ranking with 22.00 HPCG-Petaflop/s. On the HPL-MxP mixed-precision benchmark, LineShine reached 7.92 Exaflop/s for fourth place, a comparatively modest 3.6x speedup over its HPL score that points to a CPU-only design without dedicated low-precision accelerators. While impressive, "the results may say more about Beijing's desire to show self-sufficiency in computing systems than its standing in the global AI race," reports Reuters.

Reuters interviewed tech and policy experts who said that the results "do not mean that China has the world's fastest computer for AI work because of changes in the computing industry in recent years and the methods used to compile the list." The reports notes that LineShine "ranked fourth on a benchmark test designed to simulate computing work that is more similar to AI."

Jimmy Goodrich, a senior fellow at the University of California's Institute for Global Conflict and Cooperation, said: "If the hyperscalers submitted their systems, this 'world's fastest' would not crack the top five." Addison Snell, CEO of Intersect360 Research, a firm that focuses on supercomputers, added: "I'm not surprised it's the number one system. What I'm surprised by is that they submitted it and want recognition for it."

Wikipedia cofounder Larry Sanger has been indefinitely banned from editing the site after editors concluded that he violated its canvassing rules, "or in other words, calling on his followers off platform in order to influence Wikipedia's content," reports 404 Media. Sanger says the ban proves Wikipedia suppresses ideological diversity, while editors argue he was trying to mobilize an outside audience to influence internal decisions and had ignored an earlier warning. From the report: The discussion that led to the decision to ban Sanger concluded with what an editor called a "clear consensus" to ban Sanger. "There is general agreement among participants that he has engaged in off-wiki canvassing and is not here to constructively build the encyclopedia," the editor said in a note closing the discussion. "There is also a significant concern shared by many editors that his actions constitute calls for outing."

While Sanger has been railing about bias on Wikipedia for years, the specific issue here is around his WikiProject Intellectual Diversity. WikiProjects are group efforts among Wikipedia volunteers to deal with certain issues on the site. [...] Sanger's WikiProject Intellectual Diversity, as its name implies, aims to bring more intellectual diversity to the site, mostly meaning more right-leaning perspectives. Sanger's WikiProject Intellectual Diversity and its goals alone do not merit a ban according to Wikipedia's policies. The problem, according to Wikipedia editors, is that during the discussion about whether to allow WikiProject Intellectual Diversity to become an official WikiProject, Sanger invited his 91,000 followers on X to influence that discussion.

Discussions about potential bans are supposed to remain open for at least 72 hours. While consensus that Sanger had violated Wikipedia policies was clear, Sanger was banned at some point before that deadline. He was then briefly unbanned, and then again indefinitely banned once 72 hours had elapsed and the discussion about the ban closed. "Wikipedia has become more of a mob-rule anarchy than ever," Sanger said in a statement sent to me by a spokesperson. "In the kangaroo court in which a mob ousted me, Wikipedia's administrators showed that they don't appear to value details like formal charges, a designated prosecutor, basic decorum, distinction between prosecution and judge, dispassionate adjudication, and so forth. They have no proper system other than triggering a mob to selectively enforce their hodgepodge of vague rules."

"Now that same mob has blocked me for trying to bring an intellectually diverse group of thinkers and editors to the site," Sanger continued. "Subscribing to their groupthink is now an official requirement of being a member in good standing. Something must change, and now. I only wonder if the system as it currently stands can even allow the discourse necessary to fix the system."
