NASA's Commercial Spacesuit Program Just Hit a Major Snag

Par : EditorDavid
30 juin 2024 à 07:34
Slashdot reader Required Snark shared this article from Ars Technica: Almost exactly two years ago, as it prepared for the next generation of human spaceflight, NASA chose a pair of private companies to design and develop new spacesuits. These were to be new spacesuits that would allow astronauts to both perform spacewalks outside the International Space Station as well as walk on the Moon as part of the Artemis program. Now, that plan appears to be in trouble, with one of the spacesuit providers — Collins Aerospace — expected to back out, Ars has learned. It's a blow for NASA, because the space agency really needs modern spacesuits. NASA's Apollo-era suits have long been retired. The current suits used for spacewalks in low-Earth orbit are four decades old. "These new capabilities will allow us to continue on the International Space Station and allows us to do the Artemis program and continue on to Mars," said the director of Johnson Space Center, Vanessa Wyche, during a celebratory news conference in Houston two years ago. The two winning teams were led by Collins Aerospace and Axiom Space, respectively. They were eligible for task orders worth up to $3.5 billion — in essence NASA would rent the use of these suits for a couple of decades. Since then, NASA has designated Axiom to work primarily on a suit for the Moon and the Artemis Program, and Collins with developing a suit for operations in-orbit, such as space station servicing... The agency has been experiencing periodic problems with the maintenance of the suits built decades ago, known as the Extravehicular Mobility Unit, which made its debut in the 1980s. NASA has acknowledged the suit has exceeded its planned design lifetime. Just this Monday, the agency had to halt a spacewalk after the airlock had been de-pressurized and the hatch opened due to a water leak in the service and cooling umbilical unit of Tracy Dyson's spacesuit. As a result of this problem, NASA will likely only be able to conduct a single spacewalk this summer, after initially planning three, to complete work outside the International Space Station. Collins designed the original Apollo suits, according to the article. But a person familiar with the situation told Ars Technica that "Collins has admitted they have drastically underperformed and have overspent" on their work, "culminating in a request to be taken off the contract or renegotiate the scope and their budget." Ironically, the company's top's post on their account on Twitter/X is still a repost of NASA's February announcement that they're "getting a nextx-generation spacesuit" developed by Collins Aerospace, and saying that the company "recently completed a key NASA design milestone aboard a commercial microgravity aircraft." NASA's post said they needed the suit "In order to advance NASA's spacewalking capabilities in low Earth orbit and to support continued maintenance and operations at the Space Station."

Will a US Supreme Court Ruling Put Net Neutrality at Risk?

Par : EditorDavid
30 juin 2024 à 03:34
Today the Wall Street Journal reported that restoring net neutrality to America is "on shakier legal footing after a Supreme Court decision on Friday shifted power away from federal agencies." "It's hard to overstate the impact that this ruling could have on the regulatory landscape in the United States going forward," said Leah Malone, a lawyer at Simpson Thacher & Bartlett. "This could really bind U.S. agencies in their efforts to write new rules." Now that [the "Chevron deference"] is gone, the Federal Communications Commission is expected to have a harder time reviving net neutrality — a set of policies barring internet-service providers from assigning priority to certain web traffic... The Federal Communications Commission reclassified internet providers as public utilities under the Communications Act. There are pending court cases challenging the FCC's reinterpretation of that 1934 law, and the demise of Chevron deference heightens the odds of the agency losing in court, some legal experts said. "Chevron's thumb on the scale in favor of the agencies was crucial to their chances of success," said Geoffrey Manne, president of the International Center for Law and Economics. "Now that that's gone, their claims are significantly weaker." Other federal agencies could also be affected, according to the article. The ruling could also make it harder for America's Environmental Protection Agency to crack down on power-plant pollution. And the Federal Trade Commission face more trouble in court defending its recent ban on noncompete agreements. Lawyer Daniel Jarcho tells the Journal that the Court's decision "will unquestionably lead to more litigation challenging federal agency actions, and more losses for federal agencies." Friday a White House press secretary issued a statement calling the court's decision "deeply troubling," and arguing that the court had "decided in the favor of special interests".

Threads Expands Fediverse Beta, Letting Users See Replies (and Likes) on Other Fediverse Sites like Mastodon

Par : EditorDavid
30 juin 2024 à 01:34
An anonymous Slashdot reader shared this report from the Verge: Threads will now let people like and see replies to their Threads posts that appear on other federated social media platforms, the company announced on Tuesday. Previously, if you made a post on Threads that was syndicated to another platform like Mastodon, you wouldn't be able to see responses to that post while still inside Threads. That meant you'd have to bounce back and forth between the platforms to stay up-to-date on replies... [I]n a screenshot, Meta notes that you can't reply to replies "yet," so it sounds like that feature will arrive in the future. "Threads is Meta's first app built to be compatible with the fediverse..." according to a Meta blog post. "Our vision is that people using other fediverse-compatible servers will be able to follow and interact with people on Threads without having a Threads profile, and vice versa, connecting communities..." [If you turn on "sharing"...] "Developers can build new types of features and user experiences that can easily plug into other open social networks, accelerating the pace of innovation and experimentation." And this week Instagram/Threads top executive Adam Mosseri posted that Threads is "also expanding the availability of the fediverse beta experience to more than 100 countries, and hope to roll it out everywhere soon."

Could We Lower The Carbon Footprint of Data Centers By Launching Them Into Space?

Par : EditorDavid
29 juin 2024 à 22:34
The Wall Street Journal reports that a European initiative studying the feasibility data centers in space "has found that the project could be economically viable" — while reducing the data center's carbon footprint. And they add that according to coordinator Thales Alenia Space, the project "could also generate a return on investment of several billion euros between now and 2050." The study — dubbed Ascend, short for Advanced Space Cloud for European Net zero emission and Data sovereignty — was funded by the European Union and sought to compare the environmental impacts of space-based and Earth-based data centers, the company said. Moving forward, the company plans to consolidate and optimize its results. Space data centers would be powered by solar energy outside the Earth's atmosphere, aiming to contribute to the European Union's goal of achieving carbon neutrality by 2050, the project coordinator said... Space data centers wouldn't require water to cool them, the company said. The 16-month study came to a "very encouraging" conclusion, project manager Damien Dumestier told CNBC. With some caveats... The facilities that the study explored launching into space would orbit at an altitude of around 1,400 kilometers (869.9 miles) — about three times the altitude of the International Space Station. Dumestier explained that ASCEND would aim to deploy 13 space data center building blocks with a total capacity of 10 megawatts in 2036, in order to achieve the starting point for cloud service commercialization... The study found that, in order to significantly reduce CO2 emissions, a new type of launcher that is 10 times less emissive would need to be developed. ArianeGroup, one of the 12 companies participating in the study, is working to speed up the development of such reusable and eco-friendly launchers. The target is to have the first eco-launcher ready by 2035 and then to allow for 15 years of deployment in order to have the huge capacity required to make the project feasible, said Dumestier... Michael Winterson, managing director of the European Data Centre Association, acknowledges that a space data center would benefit from increased efficiency from solar power without the interruption of weather patterns — but the center would require significant amounts of rocket fuel to keep it in orbit. Winterson estimates that even a small 1 megawatt center in low earth orbit would need around 280,000 kilograms of rocket fuel per year at a cost of around $140 million in 2030 — a calculation based on a significant decrease in launch costs, which has yet to take place. "There will be specialist services that will be suited to this idea, but it will in no way be a market replacement," said Winterson. "Applications that might be well served would be very specific, such as military/surveillance, broadcasting, telecommunications and financial trading services. All other services would not competitively run from space," he added in emailed comments. [Merima Dzanic, head of strategy and operations at the Danish Data Center Industry Association] also signaled some skepticism around security risks, noting, "Space is being increasingly politicised and weaponized amongst the different countries. So obviously, there is a security implications on what type of data you send out there." Its not the only study looking at the potential of orbital data centers, notes CNBC. "Microsoft, which has previously trialed the use of a subsea data center that was positioned 117 feet deep on the seafloor, is collaborating with companies such as Loft Orbital to explore the challenges in executing AI and computing in space." The article also points out that the total global electricity consumption from data centers could exceed 1,000 terawatt-hours in 2026. "That's roughly equivalent to the electricity consumption of Japan, according to the International Energy Agency."

Citing 'Crisis' in Local Reporting, Associated Press Creates Sister Organization to Seek Grants

Par : EditorDavid
29 juin 2024 à 20:34
Founded in 1846, the not-for-profit Associated Press distributes its news stories to other news outlets. But are free online sites putting those outlets at risk? This week the Associated Press wrote that a "crisis" in local and state news reporting "shows little signs of abating" — and that it's now setting up "a sister organization that will seek to raise money" for those outlets. The organization, which will have a board of directors independent of the AP, will solicit philanthropic spending to boost this news coverage, both within the AP and through outside organizations, the news outlet said Tuesday. "We feel we have to lean in at this point, not pull back," said Daisy Veerasingham, the AP's president and CEO. "But the supporting mechanism — the local newspaper market that used to support this — can't afford to do that anymore." Veerasingham said she's been encouraged by preliminary talks with some funders who have expressed concern about the state of local journalism... The local news industry has collapsed over the past two decades, with the number of journalists working in newspapers dropping from 75,000 to 31,000 in 2022, according to Northwestern University. More than half of the nation's counties have no local news outlets or only one. The AP's CEO offered this succinct summary of their goal. "We want to add new products and services to help the industry."

90 Workers Given a Choice: Relocate Across the US, or Leave the Company

Par : EditorDavid
29 juin 2024 à 19:34
"The outdoor-apparel brand Patagonia has given 90 U.S. employees a choice," reports Business Insider: "tell the company by Friday that you're willing to relocate or leave your job." [Alternate URL here.] The employees all work in customer services, known at Patagonia as the customer-experience, or CX, team, and have been allowed to work remotely to field calls and inquiries. These workers received a text and email Tuesday morning about an "important" meeting... Two company executives, Amy Velligan and Bruce Old, told staff in a 15-minute video meeting that the team would be moving to a new "hub" model. CX employees are now expected to live within 60 miles of one of seven "hubs" — Atlanta; Salt Lake City; Reno, Nevada; Dallas; Austin; Chicago; or Pittsburgh. Workers were offered $4,000 toward relocation costs and extra paid time off. Those willing to relocate were told to do so by September 30. If CX staff are not willing to live near a hub city, they must leave the company. They were given 72 hours, until Friday, to confirm their decision... Access to company laptops and phones was shut off later that day until employees either agreed to relocate or said they wanted the severance, one affected CX worker said... Both employees who spoke to Business Insider believed this was because Patagonia didn't want to handle the increased demands of employees in states with higher costs of living. "We've been asking for raises for a long time, and they keep telling us that your wage is based on a Reno cost of living and where you choose to live is on you." According to the article, "The company hopes to bring staff together at the hubs at least once every six weeks for in-person training, company gatherings, or 'Activism Hours'." A company spokesperson described the changes as "crucial for us to build a vibrant team culture," and said there were workers who had been complaining about feeling disconnected. Though there may be another motive: "The reality is that our CX team has been running at 200% to 300% overstaffed for much of this year," she added. "While we hoped to reach the needed staffing levels through attrition, those numbers were very low, and retention remained high." One affected worker told Business Insider that the company's proposal "was very factual. If you don't live in these seven metro areas, you either need to move there or give us your stuff and hit the brick. If we don't respond by Friday, they will assume that we have chosen the severance package and we'll start that process." One worker added that the severance package they received was generous... Thanks to Slashdot reader NoWayNoShapeNoForm for sharing the article.

Lego Bricks Made From Meteorite Dust 3D Printed by Europe's Space Agency

Par : EditorDavid
29 juin 2024 à 18:34
Lego teamed up with the European Space Agency to make Lego pieces from actual meteorite dust, writes Engadget. "It's a proof of concept to show how astronauts could use moondust to build lunar structures." Consider the sheer amount of energy and money required to haul up building materials from Earth to the Moon. It would be a game changer to, instead, build everything from pre-existing lunar materials. There's a layer of rock and mineral deposits at the surface of the Moon, which is called lunar regolith... However, there isn't too much lunar regolith here on Earth for folks to experiment with. ESA scientists made their own regolith by grinding up a really old meteorite. [4.5 billion years, according to Lego's site, discovered in Africa in 2000.] The dust from this meteorite was turned into a mixture that was used to 3D print the Lego pieces. Voila. Moon bricks. They click together just like regular Lego bricks, though they only come in one color (space gray obviously.) "The result is amazing," says ESA Science Officer Aidan Cowley on the Lego site (though "the bricks may look a little rougher than usual. Importantly the clutch power still works, enabling us to play and test our designs.") "Nobody has built a structure on the Moon," Cowley said in an ESA statement. "So it was great to have the flexibility to try out all kinds of designs and building techniques with our space bricks." And the bricks will also be "helping to inspire the next generation of space engineers," according to the ESA's announcement — since they'll be on display in select Lego stores in the U.S., Canada, the U.K., Spain, France, Germany, the Netherlands, and Australia through September 20th.

Colorado's Universal Basic Income Experiment Gets Surprising Results

Par : EditorDavid
29 juin 2024 à 16:34
In November of 2022, "More than 800 people were selected to participate in the Denver Basic Income Project," reports the Colorado Sun, "while they were living on the streets, in shelters, on friends' couches or in vehicles. One group received $1,000 a month, according to the article, while a second group received $6,500 in the first month, and then $500 for the next 11 months. (And a "control" group received $50 a month.) Amazingly, about 45% of participants in all three groups "were living in a house or apartment that they rented or owned by the study's 10-month check-in point, according to the research." The number of nights spent in shelters among participants in the first and second groups decreased by half. And participants in those two groups reported an increase in full-time work, while the control group reported decreased full-time employment. The project also saved tax dollars, according to the report. Researchers tallied an estimated $589,214 in savings on public services, including ambulance rides, visits to hospital emergency departments, jail stays and shelter nights... The study, which began in November 2022 with payments to the first group of participants, has been extended for an additional eight months, until September, and organizers are attempting to raise money to extend it further.

Japan Achieves 402 TB/s Data Rate - Using Current Fiber Technology

Par : EditorDavid
29 juin 2024 à 15:34
Tom's Hardware reports that Japan's National Institute of Information and Communications Technology (working with the Aston Institute of Photonic Technologies and Nokia Bell) set a 402 terabits per second data transfer record — over commercially available optical fiber cables. The NICT and its partners were able to transmit signals through 1,505 channels over 50 km (about 31 miles) of optic fiber cable for this experiment. It used six types of amplifiers and an optical gain equalizer that taps into the unused 37 THz bandwidth to enable the 402 Tb/s transfer speed. One of the amplifiers this was demonstrated with is a thulium-based doped fiber amplifier, which uses C-band or C+L band systems. Additionally, semiconductor optical amplifiers and Raman amplifiers were used, which achieved 256 Tb/s data rate through almost 20 THz. Other amplifiers were also used for this exercise which provided a cumulative bandwidth of 25 THz for up to 119 Tb/s data rate. As a result, its maximum achievable result surpassed the previous data rate capacity by over 25 percent and increased transmission bandwidth by 35 percent. "This is achievable with currently available technology used by internet service providers..." the article points out. "With 'beyond 5G' potential speeds achievable through commercially available cables, it will likely further a new generation of internet services."

Are 'Immortal Stars' Feasting on Dark Matter in the Milky Way's Core?

Par : EditorDavid
29 juin 2024 à 14:34
"Stars very close to the center of our galaxy could be fueled by dark matter in perpetuity," writes Gizmodo, "according to a team of astronomers who recently studied the distant light sources." The group of stars, known as S-cluster stars, is just three light-years from the center of the Milky Way (for reference, we are about 26,000 light-years from the center of our galaxy, which hosts a supermassive black hole at its core). The stars are surprisingly young for their galactic neighborhood, yet they don't look like stars that simply migrated to this part of the Milky Way after forming in another location... As reported by Space.com, the research team posits that these weird stars may be accreting dark matter, which they then use as fuel to keep burning. Since models estimate there is plenty of dark matter near the galaxy's core, the stars are "forever young," as study lead author Isabelle John, an astrophysicist at the Kavli Institute for Particle Astrophysics and Cosmology told Space.com. Effectively, the stars have a long, long way to go before they start running low on fuel. The team's paper is currently hosted on the preprint server arXiv, meaning it has not yet gone through the process of peer review. Dark matter is only "seen" through its effects on other objects, the article points out — leading to lots of theories as to where it's actually located. "Earlier this year, a different team of researchers proposed that neutron stars — extremely dense stellar remnants — could actually be a source of dark matter. Last July, yet another team suggested that the Webb Telescope had detected stars that were powered by dark matter."

ChatGPT Outperforms Undergrads In Intro-Level Courses, Falls Short Later

Par : BeauHD
29 juin 2024 à 10:00
Peter Scarfe, a researcher at the University of Reading's School of Psychology and Clinical Language Sciences, conducted an experiment testing the vulnerability of their examination system to AI-generated work. Using ChatGPT-4, Scarfe's team submitted over 30 AI-generated answers across multiple undergraduate psychology modules, finding that 94 percent of these submissions went undetected and nearly 84 percent received higher grades than human counterparts. The findings have been published in the journal PLOS One. Ars Technica reports: Scarfe's team submitted AI-generated work in five undergraduate modules, covering classes needed during all three years of study for a bachelor's degree in psychology. The assignments were either 200-word answers to short questions or more elaborate essays, roughly 1,500 words long. "The markers of the exams didn't know about the experiment. In a way, participants in the study didn't know they were participating in the study, but we've got necessary permissions to go ahead with that," Scarfe claims. Shorter submissions were prepared simply by copy-pasting the examination questions into ChatGPT-4 along with a prompt to keep the answer under 160 words. The essays were solicited the same way, but the required word count was increased to 2,000. Setting the limits this way, Scarfe's team could get ChatGPT-4 to produce content close enough to the required length. "The idea was to submit those answers without any editing at all, apart from the essays, where we applied minimal formatting," says Scarfe. Overall, Scarfe and his colleagues slipped 63 AI-generated submissions into the examination system. Even with no editing or efforts to hide the AI usage, 94 percent of those went undetected, and nearly 84 percent got better grades (roughly half a grade better) than a randomly selected group of students who took the same exam. "We did a series of debriefing meetings with people marking those exams and they were quite surprised," says Scarfe. Part of the reason they were surprised was that most of those AI submissions that were detected did not end up flagged because they were too repetitive or robotic -- they got flagged because they were too good. Out of five modules where Scarfe's team submitted AI work, there was one where it did not receive better grades than human students: the final module taken by students just before they left the university. "Large language models can emulate human critical thinking, analysis, and integration of knowledge drawn from different sources to a limited extent. In their last year at the university, students are expected to provide deeper insights and use more elaborate analytical skills. The AI isn't very good at that, which is why students fared better," Scarfe explained. All those good grades Chat GPT-4 got were in the first- and second-year exams, where the questions were easier. "But the AI is constantly improving, so it's likely going to score better in those advanced assignments in the future. And since AI is becoming part of our lives and we don't really have the means to detect AI cheating, at some point we are going to have to integrate it into our education system," argues Scarfe. He said the role of a modern university is to prepare the students for their professional careers, and the reality is they are going to use various AI tools after graduation. So, they'd be better off knowing how to do it properly.

South African Researchers Test Use of Nuclear Technology To Curb Rhino Poaching

Par : BeauHD
29 juin 2024 à 07:00
Researchers in South Africa have injected radioactive material into the horns of 20 rhinos to deter poaching, aiming to leverage existing radiation detectors at borders for early detection and interception of trafficked horns. The Associated Press reports: The research, which has included the participation of veterinarians and nuclear experts, begins with the animal being tranquilized before a hole is drilled into its horn and the nuclear material carefully inserted. This week, researchers at the University of the Witwatersrand's Radiation and Health Physics Unit in South Africa injected 20 live rhinos with these isotopes. They hope the process can be replicated to save other wild species vulnerable to poaching -- like elephants and pangolins. "We are doing this because it makes it significantly easier to intercept these horns as they are being trafficked over international borders, because there is a global network of radiation monitors that have been designed to prevent nuclear terrorism," said Professor James Larkin, who heads the project. "And we're piggybacking on the back of that." According to figures by the International Union for Conservation of Nature, an international conservation body, the global rhino population stood at around 500,000 at the beginning of the 20th century. It now stands at around 27,000 due to continued demand for rhino horns on the black market. South Africa has the largest population of rhinos with an estimated 16,000, making it a hotspot with over 500 rhinos killed yearly. [...] While the idea has received support from some in the industry, the researchers have had to jump many ethical hurdles posed by critics of their methodology. Pelham Jones, chairperson of the Private Rhino Owners Association, is among the critics of the proposed method and doubts that it would effectively deter poachers and traffickers. "(Poachers) have worked out other ways of moving rhino horn out of the country, out of the continent or off the continent, not through traditional border crossings," he said. "They bypass the border crossings because they know that is the area of the highest risk of confiscation or interception." Professor Nithaya Chetty, dean of the science faculty at Witwatersrand, said the dosage of the radioactivity is very low and its potential negative impact on the animal was tested extensively.

Bipartisan Consensus In Favor of Renewable Power Is Ending

Par : BeauHD
29 juin 2024 à 03:30
An anonymous reader quotes a report from Ars Technica: One of the most striking things about the explosion of renewable power that's happening in the U.S. is that much of it is going on in states governed by politicians who don't believe in the problem wind and solar are meant to address. Acceptance of the evidence for climate change tends to be lowest among Republicans, yet many of the states where renewable power has boomed -- wind in Wyoming and Iowa, solar in Texas -- are governed by Republicans. That's partly because, up until about 2020, there was a strong bipartisan consensus in favor of expanding wind and solar power, with support above 75 percent among both parties. Since then, however, support among Republicans has dropped dramatically, approaching 50 percent, according to polling data released this week. [...] One striking thing about the new polling data, gathered by the Pew Research Center, is how dramatically it skews with age. When given a choice between expanding fossil fuel production or expanding renewable power, Republicans under the age of 30 favored renewables by a 2-to-1 margin. Republicans over 30, in contrast, favored fossil fuels by margins that increased with age, topping out at a three-to-one margin in favor of fossil fuels among those in the 65-and-over age group. The decline in support occurred in those over 50 starting in 2020; support held steady among younger groups until 2024, when the 30-49 age group started moving in favor of fossil fuels. Democrats, by contrast, break in favor of renewables by 75 points, with little difference across age groups and no indication of significant change over time. They're also twice as likely to think a solar farm will help the local economy than Republicans are. Similar differences were apparent when Pew asked about policies meant to encourage the sale of electric vehicles, with 83 percent of Republicans opposed to having half of cars sold be electric in 2032. By contrast, nearly two-thirds of Democrats favored this policy. There's also a rural/urban divide apparent (consistent with Republicans getting more support from rural voters). Forty percent of urban residents felt that a solar farm would improve the local economy; only 25 percent of rural residents agreed. Rural residents were also more likely to say solar farms made the landscape unattractive and take up too much space. (Suburban participants were consistently in between rural and urban participants.) What's behind these changes? The single biggest factor appears to be negative partisanship combined with the election of Joe Biden. Among Republicans, support for every single form of power started to change in 2020 -- fossil fuels, renewables, and nuclear. Among Democrats, that's largely untrue. Their high level of support for renewable power and aversion to fossil fuels remained largely unchanged. The lone exception is nuclear power, where support rose among both Democrats and Republicans (the Biden administration has adopted a number of pro-nuclear policies).

Apple Developing New Way To Make iPhone Batteries Easier To Replace

Par : BeauHD
29 juin 2024 à 02:02
According to a report from The Information, Apple is developing a new "electrically induced adhesive debonding" technology that would make iPhone batteries easier to replace. 9to5Mac reports: Currently, replacing an iPhone battery requires using tweezers to remove the existing battery, which is held in place by adhesive strips. Then, you must use a "specialized machine and tray" to press the new battery into place. The new process uses metal instead of foil to cover the battery, as The Information explains: "The new technology --- known as electrically induced adhesive debonding -- involves encasing the battery in metal, rather than foil as it is currently. That would allow people to dislodge the battery from the chassis by administering a small jolt of electricity to the battery, the people said. Consumers still have to pry open the iPhone themselves, which is not an easy process because of the adhesives and screws that keep the iPhone's screen sealed in place." Even with this change, however, Apple will still recommend that iPhone users visit a professional to replace their battery. If Apple's development of this new bonding technology goes according to plan, it could debut it with at least one iPhone 16 model this year. According to the report, it would then expand to all versions of the iPhone 17 next year.

Samantha Cole reports via 404 Media: A woman is suing Microsoft and two major U.S. sex toy retailers with claims that their websites are tracking users without their consent, despite promising they wouldn't do that. In a complaint (PDF) filed on June 25 in the Northern District of California, San Francisco resident Stella Tatola claims that Babeland and Good Vibrations -- both owned by Barnaby Ltd., LLC -- allowed Microsoft to see what visitors to their websites searched for and bought. "Unbeknownst to Plaintiff and other Barnaby website users, and constituting the ultimate violation of privacy, Barnaby allows an undisclosed third-party, Microsoft, to intercept, read, and utilize for commercial gain consumers' private information about their sexual practices and preferences, gleaned from their activity on Barnaby's websites," the complaint states. "This information includes but is not limited to product searches and purchase initiations, as well as the consumer's unique Microsoft identifier." The complaint claims that Good Vibrations and Babeland sites have installed trackers using Microsoft's Clarity software, which does "recording in real time," and tracks users' mouse movements, clicks or taps, scrolls, and site navigation. Microsoft says on the Clarity site that it "processes a massive amount of anonymous data around user behavior to gain insights and improve machine learning models that power many of our products and services." "By allowing undisclosed third party Microsoft to eavesdrop and intercept users' PPSI in such a manner -- including their sexual orientation, preferences, and desires, among other highly sensitive, protected information -- Barnaby violates its Privacy Policies, which state it will never share such information with third parties," the complaint states. The complaint includes screenshots of code from the sexual health sites that claims to show them using Machine Unique Identifier ("MUID") cookies that "identifies unique web browsers visiting Microsoft sites," according to Microsoft, and are used for "advertising, site analytics, and other operational purposes." The complaint claims that this violates the California Invasion of Privacy Act, the Federal Wiretap Act, and Californians' reasonable expectation of privacy.

After launching in the United States earlier this year, Apple's Vision Pro is now available to buy in China, Japan, and Singapore. "The Apple Vision Pro will also roll out to Germany, France, Australia, the UK, and Canada on July 12th, with preorders for those regions available starting today at 5AM PT," notes The Verge. Apple is documenting the international launch via a recent blog post. According to CNBC, the device starts at $4,128 (29,999 yuan) in China, compared to $3,500 in the U.S. Meanwhile, Apple is already hard at work on a more budget-friendly model. In Bloomberg's "Power On" newsletter, Apple news-breaker Mark Gurman reports today that the tech giant is "working on a cheaper headset, a second Vision Pro model and augmented-reality glasses to better compete with Meta."

Appeals Court Seems Lost On How Internet Archive Harms Publishers

An anonymous reader quotes a report from Ars Technica: The Internet Archive (IA) went before a three-judge panel Friday to defend its open library's controlled digital lending (CDL) practices after book publishers last year won a lawsuit claiming that the archive's lending violated copyright law. In the weeks ahead of IA's efforts to appeal that ruling, IA was forced to remove 500,000 books from its collection, shocking users. In an open letter to publishers, more than 30,000 readers, researchers, and authors begged for access to the books to be restored in the open library, claiming the takedowns dealt "a serious blow to lower-income families, people with disabilities, rural communities, and LGBTQ+ people, among many others," who may not have access to a local library or feel "safe accessing the information they need in public." During a press briefing following arguments in court Friday, IA founder Brewster Kahle said that "those voices weren't being heard." Judges appeared primarily focused on understanding how IA's digital lending potentially hurts publishers' profits in the ebook licensing market, rather than on how publishers' costly ebook licensing potentially harms readers. However, lawyers representing IA -- Joseph C. Gratz, from the law firm Morrison Foerster, and Corynne McSherry, from the nonprofit Electronic Frontier Foundation -- confirmed that judges were highly engaged by IA's defense. Arguments that were initially scheduled to last only 20 minutes stretched on instead for an hour and a half. Ultimately, judges decided not to rule from the bench, with a decision expected in the coming months or potentially next year. McSherry said the judges' engagement showed that the judges "get it" and won't make the decision without careful consideration of both sides. "They understand this is an important decision," McSherry said. "They understand that there are real consequences here for real people. And they are taking their job very, very seriously. And I think that's the best that we can hope for, really." On the other side, the Association of American Publishers (AAP), the trade organization behind the lawsuit, provided little insight into how the day went. When reached for comment, AAP simply said, "We thought it was a strong day in court, and we look forward to the opinion." [...] "There is no deadline for them to make a decision," Gratz said, but it "probably won't happen until early fall" at the earliest. After that, whichever side loses will have an opportunity to appeal the case, which has already stretched on for four years, to the Supreme Court. Since neither side seems prepared to back down, the Supreme Court eventually weighing in seems inevitable.
