Astronauts Take First X-Rays In Space 23

Astronauts on SpaceX's Fram2 mission successfully captured diagnostic X-ray images in orbit for the first time. The milestone gives space medicine a second imaging option beyond ultrasound and could help future crews diagnose injuries, inspect equipment, and support longer missions to the moon or beyond. Popular Science reports: Commercial off-the-shelf X-ray machines like the ice cooler-sized MinXray TR90BH now allow users to perform scans on subjects far away from traditional facilities. In 2022, [Mayo Clinic researcher Sheyna Gifford] assisted in preparing a crew to successfully generate digital X-rays while experiencing microgravity during a parabolic flight. Gifford's team then spent years collaborating with SpaceX to plan another feasibility study. This time, they didn't want to operate an X-ray machine aboard an aircraft simulating the conditions in space -- they intended to use the equipment during an orbital mission.

The process was detailed in a recently published study in the journal Radiology, and focuses on last year's Fram2 mission. Instead of days of medical training, astronauts spent only four hours learning how to use their portable radiography device. They then took preflight X-rays of a hand, forearm, chest, abdomen, and pelvis ahead of their SpaceX Falcon 9 rocket launch on March 31, 2025. Once in orbit, the team calibrated the system before testing their MinXray on the same body parts as well as a smartwatch.

Once the crew returned, a trio of independent radiologists reviewed the orbital X-ray images based on their positioning, spatial and contrast resolutions, and general scan quality. Although positioning scores were slightly decreased for the central body images, every other scan held up to similar examples created on Earth. Meanwhile, the astronauts reported that using the machine was easy despite minimal prior coaching. Looking ahead, researchers hope to conduct further X-ray tests during orbital missions, while continuing to reduce the overall size of equipment.

US Supreme Court Rules Geofence Warrants Require Constitutional Privacy Protections (theguardian.com) 97

The U.S. Supreme Court ruled 6-3 (PDF) in Chatrie v United States (No. 25-112) that geofence warrants sweeping up smartphone location data constitute searches under the Fourth Amendment. The Court found that individuals have a "reasonable expectation of privacy" in such data, even when the tracking covers only a brief period or records movements in public. "An individual has a reasonable expectation of privacy in records about his cell phone's location, and police intrude on that constitutionally protected interest when they demand the information -- even though for only a limited time, and from a third-party tech company," wrote Justice Elena Kagan. Longtime Slashdot reader schwit1 submitted the story. The Guardian reports: The use of geofence warrants is widespread, and gives law enforcement agencies the power to compel tech companies to hand over sensitive cell phone data from people at or near crime scenes. The warrants allow police and the FBI to collect this information from individuals within the radius of a virtual "fence" during a particular timeframe. But they are not restricted to requesting data for precise targets.

The Chatrie case focuses on local police's pursuit of an armed bank robber in Richmond, Virginia. He fled with $195,000. Law enforcement tracked Okello Chatrie down through their use of geofence warrants. Chatrie had opted in to an optional Google "location history" feature that documented his location every few minutes. He was eventually sentenced to 12 years in prison, after pleading guilty. Chatrie's lawyers argued that this search was overly broad and violated his fourth amendment rights, which protects individuals from "unreasonable search and seizure." Lawyers said that police's use of geofence warrants amounted to an official "search" under the fourth amendment, and didn't meet the constitution's requirements for one.

The government had argued that accessing only a short amount of cellphone location information means this tactic does not count as a fourth amendment search and accordingly, should not be afforded the same privacy protections. But the judges in the majority disagreed. The judges in the majority opinion also wrote that the government's characterization of generating location history as a voluntary choice is "meritless." They suggested that people aren't choosing to share private information with third parties and the government "just by doing the ordinary thing cellphone users do." "The point of carrying smartphones is to use what is on them," including the apps and services they provide -- many of which use location data to customize a user's experience, they said.

[...] While the majority opinion noted that police conducted a fourth amendment search by accessing Chatrie's location history data, they noted that the court of appeals will weigh in on whether the "search was reasonable, meaning that each of its steps was properly described with particularity and found to be supported by probable cause." Law enforcement has said they need geofence warrants to find suspects and witnesses -- after reaching dead ends. The US government, for its part, has argued that people can't have a "reasonable expectation of privacy" when they are in public and have allowed a third party company, such as Google, to collect and analyze phone location data.

California Sheriff Says Their Drone Disarmed a Suspect, Shares Video on Instagram (sfgate.com) 31

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.

Slate Auto's Radically Simple Electric Truck Starts At $24,950 (techcrunch.com) 204

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.

Snap's First Consumer AI Glasses Are Coming This Fall For $2,195 (theverge.com) 39

Snap is launching its first consumer augmented-reality glasses this fall for $2,195. "You can preorder a pair of Specs now at specs.com with a $200 refundable deposit, and Snap says they're expected to ship 'this fall' in the US, UK, and France," reports The Verge. From the report: This is a big moment for Snap: The company made a big entry into smart glasses with its original Spectacles in 2016, and the company has been toiling away on nonpublic AR versions of Spectacles over the past few years. CEO Evan Spiegel promised the company would launch consumer AR glasses in 2026 and even turned its smart glasses team into a separate business. The company says that Specs are "fully standalone, with no puck and no tether." (Which is perhaps a jab at Apple's Vision Pro, which is tethered to a separate battery pack.) They'll be offered in two sizes, a 47mm model weighing 132g and a 52mm model weighing 136g, and will have removable inserts that Snap says will support "a wide range of prescriptions."

You probably won't mistake Specs, with their wide, bold frames, for any of Meta's smart glasses -- Snap clearly picked a design that it wants to stand out. (They're not my style -- I don't think I can pull off the "snow goggles, but fashionable" look -- though maybe Jony Ive might like them.) They have visible light and infrared cameras, and while the Specs are recording, a little LED bar will glow in the middle of the glasses. Both of the lenses will be able to show you content, and Snap says that its display system is powered by a "proprietary liquid crystal on silicon technology" that offers a 51-degree field of view and can show 16 million colors. The lenses can also go from clear to tinted in 10 seconds, Snap says.

The Specs have two Snapdragon processors onboard, and while Snap isn't specifying exactly which ones they are, the company says that one is focused on "computer vision" while the other is focused on running AR Lenses. "Together, they enable fast hand tracking, low latency, and responsive interactions that help digital content feel anchored in the real world," Snap says. You can also expect up to four hours of battery life on a charge, which Snap says accounts for things like "audio and video playback, AI assistance, Bluetooth notifications, and more." The Specs come with a charging case that Snap says will offer four more charges for a total of 20 hours of battery.

Workers Spend As Much Time 'Botsitting' AI As Producing Useful Work, Survey Finds (yahoo.com) 49

"As the use of artificial intelligence spreads across companies worldwide, it is relieving workers of tedious old chores but creating new ones," reports the Los Angeles Times.

"Most people don't realize the amount of time that they're spending working on the tools to get the time savings that they're professing," said Paul Leonardi, Duca Family professor of technology management at UC Santa Barbara." Leonardi is one of the co-authors of the new study published by the Work AI Institute, whose contributors include academics from Stanford University and UC Berkeley. The institute is sponsored by AI company Glean... The research surveyed 6,000 digital workers across the United States, the United Kingdom, and Australia between December and January. The report found that we are in a phase of significant personal productivity gains, but few companies are translating these gains into revenue and business growth. While 75% of individuals reported a boost in productivity, only 13% of the organizations say they have seen significant business gains as a result of AI adoption, the survey found...

The reason the boost in productivity sometimes leads to waste, Leonardi said, is the time people spend correcting the bot's work and gathering the right files, documentation, and tacit knowledge required for it to produce high-quality output. "It's pretty striking the amount of time and effort people are spending," Leonardi said. Most employees now spend over six hours a week of their workday babysitting their work chatbots, the survey said. There is a "thick, mostly invisible layer of human labor holding the whole thing together," the report said. The survey found that for every hour a worker spends getting useful output from AI, they spend roughly another hour making it usable. Of the total time workers spend interacting with AI each week, 37% goes to botsitting, 36% to actually using the tool to produce work.

Part of the reason so much time disappears into botsitting is how often the tools fall short: Workers report that more than a third of AI sessions fail outright, requiring a full restart or substantial rework. Paradoxically, as more workers hand over bigger parts of their jobs to AI, they are offloading personal judgment and responsibilities to the bots. The survey found 41% of workers say they sometimes deliver AI-generated work they couldn't explain if asked... "I think what's happening with a lot of these Gen AI tools right now is we're essentially expecting individual contributors to act as managers," Leonardi said. "They're just managing these AI tools, AI agents, and we're expecting that they'll be able to produce way more, but we're not taking into account all of the work that actually goes into managing."

This problem isn't likely to go away.

German Court Holds Google Liable For False AI Overview Answers (the-decoder.com) 93

A Munich regional court has ruled (PDF) that Google can be held directly liable for false claims in AI Overviews. The case involved AI Overviews falsely linking two publishers to scams and shady business practices, with the court rejecting Google's argument that users could simply check the sources themselves. The Decoder reports: Google's AI overviews work nothing like traditional search results, the court argues. The AI rewrites and judges results "in its own words and according to its own structure," the ruling says. In the case at hand, for example, it opened with confident claims like "Yes, [company] is known for dubious business practices," then built its own structure with a summary, red flags for the alleged scam, and tips for users. The court also found that the AI overview made claims "that are not even made in the search results." None of the linked sources drew any connection between the plaintiffs and the shady companies the AI mentioned. The court called these "the defendant's own statements." Google built the AI, Google offered it to users, so Google owns what it produces, "because it alone has influence over the AI's offering and the algorithms with which the AI operates."

The court also examined existing rulings from Germany's Federal Court of Justice (BGH), which gave traditional search engines and autocomplete limited liability. The BGH had argued that search engine operators were only liable as indirect infringers because they merely made third-party content findable. A proactive duty to check results would threaten how search engines work. The Munich court found that this reasoning doesn't apply to AI overviews. A regular search engine just points to outside websites. But AI overviews generate "independent, new, and substantive statements" by evaluating and combining content from various third-party sites. And only Google can check those statements, the court said, "at least by comparing the underlying third-party websites with its own statements based on them." The court also noted that the AI overview is "by no means absolutely necessary" for using the internet. Traditional search results already help users sort through information, the AI overview is just an extra feature.
At the hearing, Google argued that users could check the linked sources themselves to verify if the AI summary was correct. It also said that these users knew "that information generated with AI should not be blindly trusted." The court rejected this.

Ladybird Browser Stops Accepting Public Pull Requests (ladybird.org) 25

The Ladybird browser isn't opposed to AI coding tools, but it's just brought a new change to their code-contributing policies.

February 23: "Ladybird adopts Rust, with help from AI." Our first target was LibJS , Ladybirdâ(TM)s JavaScript engine... I used Claude Code and Codex for the translation. This was human-directed, not autonomous code generation. I decided what to port, in what order, and what the Rust code should look like. It was hundreds of small prompts, steering the agents where things needed to go... The requirement from the start was byte-for-byte identical output from both pipelines. The result was about 25,000 lines of Rust, and the entire port took about two weeks. The same work would have taken me multiple months to do by hand.
June 5 (Friday): We will no longer accept public pull requests... A pull request no longer tells us as much as it used to about the person submitting it. A substantial patch used to imply substantial effort, and that effort was a reasonable proxy for good faith. That assumption no longer holds....

We have already seen patient, well-resourced campaigns in open source to earn maintainer trust and abuse it. What has changed is how much faster and cheaper it has become to produce work that looks like a serious contribution... Whether code was typed by hand is beside the point. What matters is who is responsible for it once it enters the browser. Ladybird is becoming a browser for real users. The people introducing changes to it must be the people who decide those changes belong in the project, and who will answer for the consequences.

As part of this change, we will close all currently open public pull requests. We are grateful for the work people put into them, but keeping the existing queue open would keep that contribution path open in practice. There is no perfect time to make this change, so we are making it now. Going forward, pull requests will only be available to project maintainers. There will not be a separate process for submitting patches by other means. We do not want to create a shadow contribution system through issues, comments, email, or forks...

Outside involvement still matters: clear bug reports, reductions, website testing, standards discussion, design discussion, security reports, and technical feedback all help move the project forward. This is the right change for Ladybird now. We are preparing to ship a browser to real users, and our development process has to match that responsibility.

A Fundamental Principle of Aeronautical Engineering Has Been Overturned (wired.com) 112

An anonymous reader quotes a report from Wired: Aerodynamic drag is a major "barrier" in high-speed airplanes, automobiles, and bullet trains. This is because a design with less aerodynamic drag allows the aircraft to move at higher speeds with less energy. When an aircraft or car body moves at high speed, a thin layer of air called the "boundary layer" is formed on its surface. This boundary layer has two states: laminar flow, in which air flows in an orderly fashion, and turbulent flow, which involves turbulence. The longer the air stays in the laminar flow state with low friction, the smaller the air resistance becomes, but as the air speed increases, it transitions to turbulent flow. The key to reducing aerodynamic drag is how to delay this transition to turbulence.

For more than 80 years, the principle of "the surface of an object must be smooth" has been the basic premise of aeronautical engineering throughout the world in order to suppress the transition to turbulence and reduce aerodynamic drag. This premise was based on the results of a 1940 study by Ichiro Tani, a Japanese aerodynamicist who quantitatively demonstrated the relationship between "surface roughness" (an indicator of the state of the machined surface) and turbulent transition, arguing that surface roughness, which was unavoidable with the manufacturing technology of the time, prevented laminar flow from being realized. However, in 1989 Tani reinterpreted the experimental data on rough-surface pipes obtained by fluid engineer Johann Nikulase in the 1930s, bringing a new perspective that "roughness may not necessarily only promote turbulent transition and increase fluid resistance." Inheriting this idea, a research group led by Yasuaki Kohama of Tohoku University experimentally demonstrated in the 1990s that fibrous rough surfaces, which have fine fibrous irregularities on their surface, have the effect of delaying transition under certain conditions.

The same Tohoku University research team recently announced a discovery that significantly advances this trend. Aiko Yakino, associate professor at Tohoku University's Institute of Fluid Science, and her research group were the first in the world to demonstrate that aerodynamic drag can be reduced by up to 43.6 percent simply by applying distributed micro-roughness (DMR), a surface roughness so fine and irregular that it cannot be distinguished by the naked eye. This technology is fundamentally different from the "rivulet (shark skin) process," which is known as a typical aerodynamic drag reduction technology. The rivulet process mimics the fine longitudinal grooves in shark skin, and by carving grooves approximately 0.1 mm wide along the direction of airflow, it aligns the vortices that occur near the wall surface of turbulent airflow areas. DMR, on the other hand, delays the switch from laminar to turbulent flow by means of random and minute irregularities. The flow zones it affects and the mechanisms it employs are based on completely different concepts.

Windows' Classic 3D Space Cadet Pinball Is Getting a Physical Re-Creation (arstechnica.com) 51

Hobbyist CNCDan is trying to build a real-world version of Windows' classic 3D Pinball for Windows -- Space Cadet, using 3D-printed flippers, bumpers, LEDs, slingshots, and a raised playfield modeled after the original virtual table. But in bringing the digital table into the real world, CNCDan has already run into several physical challenges the software never had to contend with... Ars Technica reports: After scaling and skewing the on-screen, perspective-shifted view of the Space Cadet playfield onto a 1-meter-tall table, he ended up with a rectangular playfield just 56 cm wide. That's on the smaller side for commercial pinball tables and maps to playfield bumpers that are just 53 mm wide -- way smaller than any prebuilt bumpers that are commercially available.

Once CNCDan dealt with issues with unreliable plastic microswitches for those tiny bumpers (Hall effect magnets seemed to help), he ran into a separate problem with the even smaller bumpers on the raised playfield. The wiring for those bumpers had to be arranged very carefully to avoid blocking a kickback return alley underneath, a positioning problem that the original designers of the virtual table didn't have to consider at all. CNCDan also ended up adding a physical mechanism to simulate the short delay 3D Space Cadet players may remember, when the ball dropped down a hole from the raised playfield back to the flippers below.

CNCDan says he's currently looking for artists to help him with a hand-drawn re-creation of the original Space Cadet playfield, which he doesn't want to use AI for. "I'm sure [AI] can do it, but I'd much rather give this job to a real human being," he said in the video.

Disney's 'Star Wars: The Mandalorian and Grogu' Opens to 'Mixed' Box Office Results (arstechnica.com) 87

It's "the first time in seven years that a new Star Wars film has launched on the big screen," writes CNBC. And Variety notes it's expected to earn $102 million through Monday: [B]ox office analysts are mixed on the results. On one hand, it's significant for any film to debut above $100 million in post-pandemic times. On the other, "Star Wars" is one of Hollywood's preeminent film properties, so there's an expectation of a certain level of box office. And this start is the worst for "Star Wars" since Disney bought the franchise in 2012.
CNBC cites reports 41% of tickets were sold for more expensive large-format screenings like IMAX and DolbyCinema.

So how's the movie? Rotten Tomatoes shows an 89% positive rating from moviegoers on its "popcornmeter" and a 62% average score from professional movie critics. And Ars Technica writes that "The plot is predictable, the fight scenes are meh, but you can't beat the charm of that little green Grogu." So while there's "a paint-by-numbers plot," they add that "the little green puppet pretty much carries the entire film." The new film is ... fine. It's an average Star Wars outing, and it will give families a solid Memorial Day Weekend entertainment option. It's just not the spectacular home run that might have helped launch the flagging franchise into an exciting new era, and diehard Star Wars fans hoping for more are probably going to be disappointed.
Of course, not everyone agrees. "How many nails can we realistically drive into Star Wars's coffin before it's time to give up hope of resuscitation?" writes Clarisse Loughrey for The Independent, calling it "the dullest and most inconsequential 'Star Wars' ever made." (She argues that the movie "stitches together what is clearly three episodes of the previously planned fourth season of The Mandalorian and calls it a day. There's not a whiff of effort here.")

And a reviewer at RogerEbert.com gave it one-and-a-half stars, complaining that "There's no reason for anything in this movie except the wish to make even more money...." I'm on record as despising the word "content," which was pushed by early tech moguls to devalue art as interchangeable goo in a virtual pipeline, but this washed-out, video-game-looking movie, with its murky night scenes and lack of visual depth, deserves the word. You've seen everything in it before, from the equipment, spacecraft, armor, and tactical maneuvers to the species and various types of terrain (earthlike, but cartoony)...

Even Grogu taxes our patience. Some of his cute bits could've ended with him facing the camera and doing jazz hands.

Pentagon Releases Second Batch of UFO Videos, First-Hand Testimony 62

The Pentagon released a second batch of UAP files, including 50 videos and documents showing unexplained objects over the Middle East, Syria, Iran, and in NASA recordings. Despite the reports, the agency stresses that it has found no evidence of extraterrestrial origin. The Guardian reports: In one video from the Middle East in 2019, taken "likely from an infrared sensor aboard a US military platform operating within the US Central Command area of responsibility," according to the Pentagon, three UAP are captured flying in formation over the Persian Gulf. Another formation of four unidentified objects is seen flying past vessels on the water off Iran in a video from 2022.

Footage taken over Syria in 2021 shows a mysterious object racing away at speed akin to instantaneous warp-speed acceleration from science fiction movies. Few of the objects seem to resemble flying saucers, discs or other traditionally perceived forms for UAP, although one October 2022 clip taken at an undisclosed location shows a cigar-shaped entity racing over what appears to be a residential area.

None of the videos are accompanied by explanations, and the Pentagon's all-domain anomaly resolution office (AARO) has previously stated it has no evidence to suggest any of the thousands of objects seen on video, or described in written testimony, is of extraterrestrial origin. In its May 8 release, a statement from the defense department said the public "can ultimately make up their own minds about the information contained in these files." Additionally, the information is collated from a diverse range of sources, including government agencies including several military branches, the FBI, the state department and Nasa. "Many of these materials lack a substantiated chain-of-custody," the Pentagon notes

Japan Runs Out of Robot Wolves In Fight Against Bears (popsci.com) 19

Japan's worsening bear problem has created a shortage of handmade "Monster Wolf" robots, which are $4,000 solar-powered scarecrow-like devices with glowing eyes, sensors, and blaring sounds designed to frighten the animals away. "We make them by hand. We cannot make them fast enough now. We are asking our customers to wait two to three months," company president Yuji Ohta recently told the AFP. Popular Science reports: First released in 2016 by the manufacturer Ohta, Monster Wolf was originally designed to ward off the agricultural foes like boars, deer, and the island nation's Asian black bear (Ursus thibetanus) and brown bear (Ursus arctos) populations. The creative solution quickly went viral for its red LED eyes and menacing fangs -- as well as its admittedly odd, furry pipe frame.

Starting at around $4,000, each bespoke Monster Wolf is now equipped with battery power, solar panels, and detection sensors. Its speakers are programmed with over 50 audio clips including human voices and sirens audible over half a mile away. These aren't assembly line products, however. Each Monster Wolf is custom made, and Ohta simply can't keep up with the current demand.

[...] Ohta told the AFP that amid the ongoing crisis, there has been "growing recognition" that Monster Wolf is "effective in dealing with bears." The main customer base remains farmers, but orders are also coming from golf courses and rural workers. Upgraded versions will soon include wheels to actually chase animals and patrol preset routes. There are also plans to release a handheld version for outdoor enthusiasts and schoolchildren. Until Ohta catches up with its orders, residents and visitors are encouraged to review the Japanese government's own bear safety tips.

CUDA Proves Nvidia Is a Software Company (wired.com) 46

Nvidia's real AI moat isn't "a piece of hardware," writes Wired's Sheon Han. It's CUDA: a mature, deeply optimized software ecosystem that keeps machine-learning workloads tied to Nvidia GPUs. An anonymous reader quotes a report from Wired: What sounds like a chemical compound banned by the FDA may be the one true moat in AI. CUDA technically stands for Compute Unified Device Architecture, but much like laser or scuba, no one bothers to expand the acronym; we just say "KOO-duh." So what is this all-important treasure good for? If forced to give a one-word answer: parallelization. Here's a simple example. Let's say we task a machine with filling out a 9x9 multiplication table. Using a computer with a single core, all 81 operations are executed dutifully one by one. But a GPU with nine cores can assign tasks so that each core takes a different column -- one from 1x1 to 1x9, another from 2x1 to 2x9, and so on -- for a ninefold speed gain. Modern GPUs can be even cleverer. For example, if programmed to recognize commutativity -- 7x9 = 9x7 -- they can avoid duplicate work, reducing 81 operations to 45, nearly halving the workload. When a single training run costs a hundred million dollars, every optimization counts.

Nvidia's GPUs were originally built to render graphics for video games. In the early 2000s, a Stanford PhD student named Ian Buck, who first got into GPUs as a gamer, realized their architecture could be repurposed for general high-performance computing. He created a programming language called Brook, was hired by Nvidia, and, with John Nickolls, led the development of CUDA. If AI ushers in the age of a permanent white-collar underclass and autonomous weapons, just know that it would all be because someone somewhere playing Doom thought a demon's scrotum should jiggle at 60 frames per second. CUDA is not a programming language in itself but a "platform." I use that weasel word because, not unlike how The New York Times is a newspaper that's also a gaming company, CUDA has, over the years, become a nested bundle of software libraries for AI. Each function shaves nanoseconds off single mathematical operations -- added up, they make GPUs, in industry parlance, go brrr.

A modern graphics card is not just a circuit board crammed with chips and memory and fans. It's an elaborate confection of cache hierarchies and specialized units called "tensor cores" and "streaming multiprocessors." In that sense, what chip companies sell is like a professional kitchen, and more cores are akin to more grilling stations. But even a kitchen with 30 grilling stations won't run any faster without a capable head chef deftly assigning tasks -- as CUDA does for GPU cores. To extend the metaphor, hand-tuned CUDA libraries optimized for one matrix operation are the equivalent of kitchen tools designed for a single job and nothing more -- a cherry pitter, a shrimp deveiner -- which are indulgences for home cooks but not if you have 10,000 shrimp guts to yank out. Which brings us back to DeepSeek. Its engineers went below this already deep layer of abstraction to work directly in PTX, a kind of assembly language for Nvidia GPUs. Let's say the task is peeling garlic. An unoptimized GPU would go: "Peel the skin with your fingernails." CUDA can instruct: "Smash the clove with the flat of a knife." PTX lets you dictate every sub-instruction: "Lift the blade 2.35 inches above the cutting board, make it parallel to the clove's equator, and strike downward with your palm at a force of 36.2 newtons."
"You can begin to see why CUDA is so valuable to Nvidia -- and so hard for anyone else to touch," writes Han. "Tuning GPU performance is a gnarly problem. You can't just conscript some tender-footed undergrad on Market Street, hand them a Claude Max plan, and expect them to hack GPU kernels. Writing at this level is a grindsome enterprise -- unless you're a cracker-jack programmer at DeepSeek..."

Han goes on to argue that rivals like AMD and Intel offer competitive specs on paper, but their software stacks have struggled with bugs, compatibility issues, and weak adoption. As a result, Nvidia has built an Apple-like moat around AI computing, leaving the industry dependent on its expensive hardware.

Will Maryland's Utility Bills Increase $1.6B to Support Other States' Datacenters? (tomshardware.com) 74

To upgrade its grid for data centers, PJM Interconnection (which serves 13 states) plans to spend $22 billion — and charge nearly $2 billion of that to customers in Maryland, argues Maryland's Office of People's Counsel. The money "will be recovered in rates for decades" and "drive up Maryland customer bills by $1.6 billion over the next ten years alone," they said Friday, announcing an official complaint filed with America's Federal Energy Regulatory Commission.

Extra demand is expected from Ohio, Pennsylvania, and Illinois "where demands driven by data centers are projected to grow substantially by 2036," they explain. But that means that Maryland customers "are subsidizing data center-driven transmission buildout by virtue of geographic proximity..." Tom's Hardware explains: That means an extra $823 million for residential (approx. $345 per customer), $146 million for commercial (approx. $673 per customer), and $629 million for industrial customers (approx. $15,074 per customer)... "Maryland customers have neither caused the need for these billions in new transmission projects nor will they meaningfully benefit from them," [according to Maryland People's Counsel David S. Lapp]....

This is one of the biggest reasons why many AI hyperscalers are facing pushback from the communities where they intend to place their data centers. At the moment, around 69 jurisdictions have passed some sort of moratorium on projects like these, and a survey has shown that nearly half of Americans do not want a data center in their neighborhood. Debates around these projects are passionate, with a few cases turning violent and even resulting in shootings (thankfully, without any casualties), especially as many feel that the construction of these power-hungry assets is threatening their lifestyles and quality of life.

LinkedIn Profile Visitor Lists Belong to the People, Says Noyb (theregister.com) 28

A LinkedIn user in the EU is challenging Microsoft's refusal to provide a full list of profile visitors under GDPR Article 15, arguing that the data should be available for free because LinkedIn processes it and sells a more complete version to Premium users. Privacy group Noyb says the case could set a broader precedent over whether companies can monetize user-related data while denying access to the same data through GDPR requests. "Selling data to its own users is a popular practice among companies," Noyb data protection lawyer Martin Baumann said of the case. "In reality, however, people have the right to receive their own data free of charge." The Register reports: Take a look at the language of Article 15, and it's pretty clear: data subjects (i.e., users) have the right to a copy of any and all data concerning them that's been processed by the provider. A full list of profile visitors seemingly should fall under Article 15 data -- even if it's normally reserved for paying users and presented to them in a nicer way, it should still be accessible to free users who actually request it. [...] Noyb acknowledges there's a clear bit of legal fuzz stuck in this corner of the GDPR when it comes to premium service offerings. "If any business processes a person's personal data, this information is generally covered by their right of access under the GDPR," Baumann told The Register. "It does not matter that the business would prefer to sell the data to the data subject or that it would be harmful for their business model if they would."

There's only one exception in Article 15 that would give LinkedIn an out, Baumann told us, and that's the last paragraph, which says a person's right to their data can't adversely affect the rights and freedoms of others. Were LinkedIn to argue that it had to protect the identities of people who visited a data subject's profile, they could have an excuse. But not a good one, in Baumann's opinion. "Since LinkedIn does provide information about profile visits to paying Premium members, it cannot consider that disclosing the data would adversely affect the rights of the visitors whose data is disclosed," the Noyb lawyer explained. "Otherwise, providing this information to Premium users would be unlawful too."

What seems to be the sticking point here is where right of access begins and a company's right to make money off data they hold (data that was, ahem, supplied by users) ends. Baumann said he hopes this case can clear the legal air. "We expect a clarification concerning the fact that personal data that can be accessed when a user pays for it is also covered by their right of access," he explained. [...] Baumann said there are numerous other cases where similar legal clarification would be appreciated, citing the example of a bank that is unwilling to provide access to account statements in response to a GDPR request, but is happy to hand over similar data for a fee. "A precedent would be welcomed," Baumann said.
A LinkedIn spokesperson told The Register: "Not only is it incorrect that only Premium members can see who has viewed their profile, but we also satisfy GDPR Article 15 by disclosing the information at issue via our Privacy Policy."

First Tesla Semi Rolls Off High-Volume Production Line (electrek.co) 138

Tesla has produced the first Semi from its new high-volume production line at Gigafactory Nevada, a milestone for the long-delayed electric Class 8 truck program after years of pilot builds and delays. Electrek reports: The Tesla Semi has had one of the longest gestation periods in Tesla's history. First unveiled in 2017, the truck was originally promised for production in 2019. That target slipped repeatedly -- to 2020, then 2021, then 2022 -- before Tesla finally delivered a handful of units to PepsiCo in late 2022. Those early trucks were essentially hand-built on a pilot line. Tesla spent the next three years refining the design, cutting roughly 1,000 lbs from the truck, and building out a dedicated factory adjacent to Gigafactory Nevada in Sparks. The company revealed the final production specs in February, confirming two trims: a Standard Range with 325 miles at full 82,000-lb gross combination weight, and a Long Range with 500 miles of range.

Tesla is quoting $290,000 for the 500-mile Long Range version and roughly $260,000 for the Standard Range -- making it the lowest-priced Class 8 battery electric tractor on the market. The shift from a pilot line to a high-volume production line is significant. Tesla's Semi factory is designed for an annual capacity of 50,000 trucks, though the company will ramp gradually. Analysts project deliveries between 5,000 and 15,000 units in 2026, but that sounds way too optimistic. [...] Both trims feature an 800-kW tri-motor drivetrain producing 1,072 hp and support 1.2-MW Megacharger speeds, restoring 60% of range in roughly 30 minutes -- conveniently timed around a driver's mandatory rest break. Tesla has opened its first Megacharger station in Ontario, California, and has mapped 66 Megacharger locations across 15 states.

Supreme Court Hears Case On How To Label Risks of Popular Weed Killer (npr.org) 85

An anonymous reader quotes a report from NPR: A divided U.S. Supreme Court on Monday heard a dispute over labels on the popular Roundup weed killer, which thousands of people blame for their cancers. How the Supreme Court rules could have implications for tens of thousands of lawsuits against Roundup maker Monsanto, which is now owned by Bayer. The case centers on who decides about warning labels on chemicals: the federal government -- or states or juries. [...] The justices will not be evaluating whether glyphosate causes cancer. Rather, they'll consider who should decide what appears on warning labels and whether states have a role to play after the EPA weighs in.

The current U.S. solicitor general backed Monsanto. Sarah Harris, his principal deputy, said the Environmental Protection Agency is in the driver's seat, not anyone in Missouri. "Missouri thus requires adding cancer warnings but federal law requires EPA to approve new warnings and tasks EPA with deciding what label changes would mitigate any health risks," Harris argued. "State law must give way." Several justices, including Brett Kavanaugh, appeared to agree with Monsanto's argument about the need for a single, uniform standard across the country.

But others, like Chief Justice John Roberts, wondered what would happen if the federal government moved more slowly than states did, who wanted to act quickly on information about new dangers. "Well, it does undermine the uniformity," Roberts said. "On the other hand, if it turns out they were right, it might have been good if they had an opportunity to do something, to call this danger to the attention of people while the federal government was going through its process," he said about states.

Justice Ketanji Brown Jackson asked about the emergence of new science, and the EPA's reviews. "There's a 15-year window between when that product has to be re-registered again and lots of things can happen in science, in terms of development about the product," she said. Bayer, which now owns Monsanto, only sells Roundup that contains glyphosate to farmers and businesses these days. Bayer has been pushing to resolve scores of the residential cases through a sweeping settlement, trying to put the costly claims behind it.

Fans Angry Over Pokemon Go Champion's Disqualification For Allegedly Shaking the Table (aftermath.site) 47

It's "the curious case of... the Pokémon Go pro who celebrated too hard," reports the gaming news site Aftermath. It all started on the first weekend in April... Firestar73, a competitive Pokémon Go player who placed seventh at last year's world championships, managed to narrowly cinch a game-five finals win at the 2026 Pokémon Orlando Regional Championships after battling his way out of the dreaded losers' bracket. As stress and adrenaline gave way to relief, Firestar73 stood up from his chair, threw off his headphones, raised his arms in a sort of victorious flexing motion, and then fist pumped for good measure. Immediately afterward, he politely shook his opponent's hand... [T]he tournament's staff went on to deem Firestar73's conduct "unsportsmanlike" and stripped him of his win.
"After weeks of fans flooding The Pokémon Company's social channels to demand a repeal of the ruling, the company has finally issued a statement," reports Kotaku. "Spoilers: It will not be reverting its decision." Their official statement? "[D]uring game one of the bracket reset series, a player was issued a Warning for the action of hitting and shaking the table during gameplay. Actions such as these can have a negative impact on the experience of participants and disturb the match in progress. Then, during game five, this same player's behavior continued to be disruptive, including shaking the table to the point that there was a disruption to the broadcast experience. These repeated infractions resulted in a penalty that was escalated to Game Loss. "
Meanwhile, Aftermath now reports, Firestar73 "has disputed Play! Pokémon's account of events entirely "The 'incident' you are now, for the first time, claiming was the basis of the decision did not affect the gameplay at all, yet decided the whole tournament," he wrote on Twitter. "Section 2.1 requires a 'clear explanation of any infraction and its penalty,' and I was never given this as the basis at all."

NiteTimeClasher, who won the tournament by disqualification, doesn't seem pleased either. "Was not my decision," he appears to have written in a Pokémon Discord. "Firestar is the Orlando regional champion. Hope you all understand." Others have attempted to divine what the company meant by a "disruption to the broadcast experience," and what they've found doesn't look all that severe.

Not long after Play! Pokémon handed down its edict, one judge who was not involved in this particular match, Professor Rex, publicly voiced his outrage. "As a judge I'm not supposed to discuss ruling[s] publicly," he wrote. "However, I also believe that as a judge my job is to give players a fair space to compete. If a player in a high stakes battle can lose out on thousands of dollars for shaking the table, what kind of space have we built? If the table can't handle the intensity of the competition, that's not the players' fault. I've judged multiple Go regionals, [and] I just can't support how this was handled."

After posting internal correspondence meant for judges and asking "some questions they didn't like" in the Discord for those who judge and otherwise help out at Pokémon events, Rex was banned from the Discord. That's when, to the extent they had not already, things spun out of control. Rex went on to share judges' personal information in a perhaps-misguided attempt at forcing transparency, which caused other judges — some of whom mostly agreed with him — to call him out and take issue with his conduct. As of now, almost no one is happy.

Meta Is Warned That Facial Recognition Glasses Will Arm Sexual Predators (wired.com) 90

An anonymous reader quotes a report from Wired: More than 70 civil liberties, domestic violence, reproductive rights, LGBTQ+, labor, and immigrant advocacy organizations are demanding that Meta abandon plans to deploy face recognition on its Ray-Ban and Oakley smart glasses, warning that the feature -- reportedly known inside the company as "Name Tag" -- would hand stalkers, abusers, and federal agents the ability to silently identify strangers in public. The coalition, which includes the ACLU, the Electronic Privacy Information Center, Fight for the Future, Access Now, and the Leadership Conference on Civil and Human Rights, is demanding Meta kill the feature before launch, after internal documents surfaced showing the company hoped to use the current "dynamic political environment" as cover for the rollout, betting that civil society groups would have their resources "focused on other concerns."

Name Tag, as revealed in February by The New York Times, would work through the artificial intelligence assistant built into Meta's smart glasses, allowing wearers to pull up information about people in their field of view. Engineers have reportedly been weighing two versions of the feature: one that would only identify people the wearer is already connected to on a Meta platform, and a broader version that could recognize anyone with a public account on a Meta service such as Instagram. The coalition wants Meta to scrap the feature entirely. In a letter to CEO Mark Zuckerberg on Monday, it argues that face recognition in inconspicuous consumer eyewear "cannot be resolved through product design changes, opt-out mechanisms, or incremental safeguards." Bystanders in public have no meaningful way to consent to being identified, it says.

Meta is also urged to disclose any known instances of its wearables being used in stalking, harassment, or domestic violence cases; disclose any past or ongoing discussions with federal law enforcement agencies, including Immigration and Customs Enforcement and Customs and Border Protection, about the use of Meta wearables or data from them; and commit to consulting civil society and independent privacy experts before integrating biometric identification into any consumer device. "People should be able to move through their daily lives without fear that stalkers, scammers, abusers, federal agents, and activists across the political spectrum are silently and invisibly verifying their identities and potentially matching their names to a wealth of readily available data about their habits, hobbies, relationships, health, and behaviors," write the groups, which also include Common Cause, Jane Doe Inc., UltraViolet, the National Organization for Women, the New York State Coalition Against Domestic Violence, the Library Freedom Project, and Old Dykes Against Billionaire Tech Bros, among others.
