IPv6 usage briefly reached 50% across Google services for the first time, marking a major milestone for a protocol created in 1998 to solve IPv4's address shortage. Tom's Hardware reports: [...] IPv6 was dismissed early on as a headache-inducing, hard-to-implement complication that would hardly ever gain any traction -- despite offering 2^128 possible numbers, solving all network number assignments in one fell swoop. That changed over time by force of necessity, and Google's tracking graph shows that for a brief moment in time on March 28, 50% of worldwide users accessed the service over an IPv6 connection, marking a historic first. APNIC's stats show that the protocol is in use by 43% of the world, with Asia and the Americas inching ever close to those 50%. Cloudflare, meanwhile, shows that 40% of traffic is done in IPv6, an actually impressive figure if you consider it's measuring actual transferred packets rather than just counting addresses.

The tried-and-true IPv4 and its well-known 123.456.789.123 format from 1980 offers ~4.3 billion addresses in theory, and around 3.7 billion in practice. That always sounded like a lot, but nobody could have predicted just how rapid the explosion of the Internet would be. IANA, the entity controlling the North-American IPv4 space, ran out of IPv4 addresses around 2011, while its European equivalent RIPE NCC could spare no more four-octet addresses nearly seven years ago in 2019. Asian, African, and Latin-American IP registries equally ran out during that timeframe.

An anonymous reader quotes a report from UploadVR: A group of independent researchers built a device that can artificially induce smell using ultrasound, with no consumable cartridges required. [...] The team of four are Lev Chizhov, Albert Yan-Huang, Thomas Ribeiro, Aayush Gupta. Chizhov is a neurotech entrepreneur with a background in math and physics, Yan-Huang is a researcher at Caltech with a background in computation and neural systems, and Ribeiro and Gupta are co-researchers on the project with software engineering and AI expertise.

Instead of targeting your nose at all, the device directly targets the olfactory bulb in your brain with "focused ultrasound through the skull." The researchers say that as far as they're aware, no one has ever done this before, even in animals. A challenge in targeting the olfactory bulb is that it's buried behind the top of your nose, and your nose doesn't provide a flat surface for an emitter. Ultrasound also doesn't travel well through air. The solution the researchers came up with was to place the emitter on your forehead instead, with a "solid, jello-like pad for stability and general comfort," and the ultrasound directed downward towards the olfactory bulb.

To determine the best placement, they say they used an MRI of one of their skulls to "roughly determine where the transducer would point and how the focal region (where ultrasound waves actually concentrate) aligned with the olfactory bulb (the target for stimulation)". [...] According to the researchers, they were able to induce the sensation of fresh air "with a lot of oxygen", the smell of garbage "like few-day-old fruit peels," an ozone-like sensation "like you're next to an air ionizer," and a campfire smell of burning wood. While technically head-mounted, the current device does require being held up with two hands. But as with all such prototypes, it likely could be significantly miniaturized.

Some Japanese bullet trains will soon support premium private suites this October, featuring windows with embedded 5G antennas for steadier onboard Wi-Fi and NTT noise-cancelling cabin tech to reduce train noise. The 5G window antennas are designed to maintain line-of-sight connections as trains race past base stations at up to 285 km/h. The Register reports: Rail operator JR Central announced the new tech late last month and will initially deploy a couple of the suites on six trains. The carrier explained that the antennas come from a Japanese company called AGC that weaves microscopic wires through glass to form an antenna. JR Central will connect the windows to an on-train Wi-Fi router.

AGC says rival tech relies on 5G signals reaching a train and then bouncing around inside before reaching the Wi-Fi unit. The company says antennas woven into train windows maintain line of sight to nearby 5G base stations. That matters because JR Central's Shinkansen can achieve speeds of up to 285 km/h, which means they speed past cellular network base stations so quickly that it's frequently necessary to reconnect to another radio. AGC says keeping a line of sight connection means its antennas allow increased 5G signal strength, so Wi-Fi service on board trains should be more stable and speedy.

The sound-deadening kit JR Central will deploy is called Personalized Sound Zone (PSZ) and comes from Japan's tech giant NTT. The tech uses the same principles applied to noise-cancelling headphones -- determine the waveform of sound and project an inversion of that waveform that cancels out ambient noise.

In an interview with Fox News, Ford CEO Jim Farley warned that allowing Chinese vehicle imports could put nearly a million U.S. jobs at risk. He said China's heavily subsidized auto industry has enough excess capacity to supply the entire U.S. market, while also raising serious cybersecurity concerns given how much data modern connected cars collect. Ars Technica reports: "First of all, the Chinese have huge direct support for their auto companies," Farley said, while noting that China has the ability to build an additional 21 million vehicles a year on top of the 29 million that are expected to roll off Chinese production lines in 2026. "They have enough capacity in China to cover all the manufacturing, all the vehicle sales in the United States," Farley said.

"Manufacturing is the heart and soul of our country, and for us to lose those exports would be devastating for our country," he continued, before pointing out the cybersecurity worries about Chinese cars. "All the vehicles have 10 cameras. They can collect a lot of data," he said.

Farley has praised Chinese EVs like the Xiaomi SU7, even going on podcasts to sing its praises. But he believes Ford's forthcoming affordable Kentucky-built EVs, due to start hitting dealerships next year, have what it takes to be competitive. When asked about new car prices rising an average of 2 percent last year, Farley repeatedly said that Ford had "worked with the administration" so that there's "essentially no big impact" of the Trump tariffs. The CEO justified the rising costs by pointing to the F-150's sales as proof of its value.

Cal is moving its flagship scheduling software from open source to a proprietary license, arguing that AI coding tools now make it much easier for attackers to scan public codebases for vulnerabilities. "Open source security always relied on people to find and fix any problems," said Peer Richelsen, co-founder of Cal. "Now AI attackers are flaunting that transparency." CEO Bailey Pumfleet added: "Open-source code is basically like handing out the blueprint to a bank vault. And now there are 100x more hackers studying the blueprint." The company says it still supports open source and is releasing a separate Cal.diy version for hobbyists, but doesn't want to risk customer booking data in its commercial product. ZDNet reports: When Cal was founded in 2022, Bailey Pumfleet, the CEO and co-founder, wrote, "Cal.com would be an open-source project [because] limitations of existing scheduling products could only be solved by open source." Since Cal was successful and now claims to be the largest Next.js project, he was on to something. Today, however, Pumfleet tells me that AI programs such as "Claude Opus can scour the code to find vulnerabilities," so the company is moving the project from the GNU Affero General Public License (AGPL) to a proprietary license to defend the program's security.

[...] Cal also quoted Huzaifa Ahmad, CEO of Hex Security, "Open-source applications are 5-10x easier to exploit than closed-source ones. The result, where Cal sits, is a fundamental shift in the software economy. Companies with open code will be forced to risk customer data or close public access to their code." "We are committed to protecting sensitive data," Pumfleet said. "We want to be a scheduling company, not a cybersecurity company." He added, "Cal.com handles sensitive booking data for our users. We won't risk that for our love of open source."

While its commercial program is no longer open source, Cal has released Cal.diy. This is a fully open-source version of its platform for hobbyists. The open project will enable experimentation outside the closed application that handles high-stakes data. Pumfleet concluded, "This decision is entirely around the vulnerability that open source introduces. We still firmly love open source, and if the situation were to change, we'd open source again. It's just that right now, we can't risk the customer data."

Amazon is buying satellite communications company Globalstar for $10.8 billion to expand its Leo satellite-internet network and compete more directly with SpaceX's Starlink. The deal also includes a partnership with Apple to support satellite connectivity for iPhones and Apple Watches, with Amazon planning voice, data, and messaging services starting in 2028. The New York Times reports: Leo was Amazon's move to enter the market for beaming high-speed internet to the ground from orbit. That is an arena dominated by Elon Musk's SpaceX, which operates the Starlink satellite-internet service. Starlink, which has thousands of satellites in orbit, already serves several million customers around the world. This month, SpaceX filed to go public in what is shaping up to be one of the largest-ever initial public offerings. Mr. Musk has valued SpaceX -- which has landed contracts with federal agencies such as NASA and the Department of Defense -- at more than $1 trillion. Other companies are racing to catch up to what Mr. Musk has built for space.

Globalstar, founded in 1991, is a Louisiana-based global telecommunications company. It operates networks of low-Earth orbiting satellites to provide internet connectivity to customers. Paul Jacobs, Globalstar's chief executive, said in a statement that together, the two companies "will advance innovations in digital connectivity."

alternative_right shares a report from 404 Media: An independent privacy audit of Microsoft, Meta, and Google web traffic in California found that the companies may be violating state regulations and racking up billions in fines. According to the audit from privacy search engine webXray, 55 percent of the sites it checked set ad cookies in a user's browser even if they opted out of tracking. Each company disputed or took issue with the research, with Google saying it was based on a "fundamental misunderstanding" of how its product works.

The webXray California Privacy Audit viewed web traffic on more than 7,000 popular websites in California in the month of March and found that most tech companies ignore when a user asks to opt-out of cookie tracking. California has stringent and well defined privacy legislation thanks to its California Consumer Privacy Act (CCPA) which allows users to, among other things, opt out of the sale of their personal information. There's a system called Global Privacy Control (GPC), which includes a browser extension that indicates to a website when a user wants to opt out of tracking.

According to the webXray audit, Google failed to let users opt out 87 percent of the time. "Google's failure to honor the GPC opt-out signal is easy to find in network traffic. When a browser using GPC connects to Google's servers it encodes the opt-out signal by sending the code 'sec-gpc: 1.' This means Google should not return cookies," the audit said. "However, when Google's server responds to the network request with the opt-out it explicitly responds with a command to create an advertising cookie named IDE using the 'set-cookie' command. This non-compliance is easy to spot, hiding in plain sight."

The audit said that Microsoft fails to opt out users in the same way and has a failure rate of 50 percent in the web traffic webXray viewed. Meta's failure rate was 69 percent and a bit more comprehensive. "Meta instructs publishers to install the following tracking code on their websites. The code contains no check for globally standard opt-out signals -- it loads unconditionally, fires a tracking event, and sets a cookie regardless of the consumer's privacy preferences," the audit said. It showed a copy of Meta's tracking data which contains no GPC check at all.

UK Prime Minister Keir Starmer said social media platforms should remove addictive infinite-scroll features for young users as Britain considers new child-safety measures. "We're consulting on whether there should be a ban for under 16s," Starmer told BBC Radio. "But I think equally important, the addictive scrolling mechanisms are really problematic to my mind. They need to go." Reuters reports: Britain, like other countries, is considering restricting access to social media for children and it is testing bans, curfews and app time limits to see how they impact sleep, family life and schoolwork. Social media companies had designed algorithms that were intended to encourage addictive behavior, and parents were asking the government to intervene, Starmer said.

[...] More than 45,000 people had already responded to its consultation on children's online safety, the UK government said, adding that there was still time to contribute before a deadline of May 26. "We want to hear from mums and dads who are worried about the amount of time their children spend online and what they are viewing," Technology Secretary Liz Kendall said on Monday. "We want to hear from teenagers who know better than anyone what it is like to grow up in the age of social media. And we want to hear from families about their views on curfews, AI chatbots and addictive features."

An anonymous reader quotes a report from Bloomberg: Alphabet's Google is facing billions of dollars in potential damage claims as part of mass arbitration tied to the company's online search and advertising technology businesses, which courts have ruled were illegal monopolies. Advertisers are banding together to seek payouts through mass arbitration proceedings. While many companies that displayed ads purchased through Google -- including USA Today Co. and Advance Publications -- have sued for damages since the rulings in 2024, advertiser contracts with the search giant require mandatory arbitration over legal disputes.

In arbitration, legal disputes are handled by a mediator, a process that tends to favor companies in individual claims. Mass arbitration -- where 25 or more claims against the same company are pooled together -- have become more common and provide a greater likelihood of settlement awards for claimants. Ashley Keller, a Chicago lawyer whose firm has handled mass arbitrations against DoorDash, Postmates and TurboTax-maker Intuit, said he's already signed up a "significant number" of advertisers to participate in claims against Google. The first of those are expected to be filed this week.

"Two federal judges have already adjudicated Google to be a monopolist," Keller said in an interview with Bloomberg. "It seems sensible to seek redress." Keller, who is also representing Texas and other states in a lawsuit against Google for monopolization of advertising technology, estimates potential claims for online search and display ads could reach $218 billion or more, based on calculations from an economist his firm has hired. Similar mass arbitrations have lasted 12 to 24 months between the filing of claims and resolution, he said. "Given the nature of these matters, we cannot estimate a possible loss," Google said in a recent corporate filing. "We believe we have strong arguments against these open claims and will defend ourselves vigorously."

Researchers at the University of Southern California say they've developed a memristor memory device that continued operating at 700 degrees Celsius. "And crucially, 700 degrees was not the limit, it was simply as hot as their testing equipment could go," adds ScienceAlert. "The device showed no signs of failing." From the report: The device is called a memristor and it's a nanoscale component that can both store information and perform computing operations. Think of it as a tiny sandwich with two electrode layers on the outside and a thin ceramic filling in the middle. The team built theirs from tungsten, the metal with the highest melting point of any element, combined with a ceramic called hafnium oxide, and with a layer of graphene at the bottom. Each material can withstand enormous heat. Together, they turned out to be extraordinary.

What makes graphene the key ingredient is the way it interacts with tungsten at the atomic level. In a conventional device, heat causes metal atoms to drift slowly through the ceramic layer until they bridge the two electrodes, short circuiting everything and leaving the device permanently broken. Graphene stops that process dead. Its surface chemistry with tungsten is ... almost like oil and water. Tungsten atoms that drift toward the graphene find they simply cannot take hold, no anchor, no short circuit, no failure. The team used advanced electron microscopy and quantum level computer simulations to understand exactly why, turning a single lucky result into a repeatable principle. The findings have been published in the journal Science.

"The new Linux kernel was released and it's kind of a big deal," writes longtime Slashdot reader rexx mainframe. "Here is what you can expect." Linuxiac reports: A key update in Linux 7.0 is the removal of the experimental label from Rust support. That (of course) does not make Rust a dominant language in kernel development, but it is still an important step in its gradual integration into the project. Another notable security-related change is the addition of ML-DSA post-quantum signatures for kernel module authentication, while support for SHA-1-based module-signing schemes has been removed.

The kernel now includes BPF-based filtering for io_uring operations, providing administrators with improved control in restricted environments. Additionally, BTF type lookups are now faster due to binary search. At the same time, this release continues ongoing cleanup in the kernel's lower layers. The removal of linuxrc initrd code advances the transition to initramfs as the sole early-userspace boot mechanism.

Linux 7.0 also introduces NULLFS, an immutable and empty root filesystem designed for systems that mount the real root later. Plus, preemption handling is now simpler on most architectures, with further improvements to restartable sequences, workqueues, RCU internals, slab allocation, and type-based hardening. Filesystems and storage receive several updates as well. Non-blocking timestamp updates now function correctly, and filesystems must explicitly opt in to leases rather than receiving them by default. Phoronix has compiled a list of the many exciting changes.

Linus Torvalds himself announced the release, which can be downloaded directly from his git tree or from the kernel.org website.

Linux 7.0 has a major new version number but it's "largely a numbering reset [...], not a sign of some unusually disruptive release," notes Linuxiac.

According to the Financial Times, Meta is developing an AI avatar of Mark Zuckerberg that could interact with employees using his voice, image, mannerisms, and public statements, "so that employees might feel more connected to the founder through interactions with it." The Verge reports: Meta may start allowing creators to make AI avatars of themselves if the experiment with Zuckerberg succeeds, according to the Financial Times. [...] Zuckerberg is involved in training the AI avatar, the Financial Times reports, and has also started spending five to 10 hours per week coding on Meta's other AI projects and participating in technical reviews.

Critics say social media is engineered to be as addictive as tobacco or gambling, writes the Washington Post — while adding that "the science has been moving in parallel with the court's recognition." A growing body of research links heavy social media use not only to declines in mental health but to measurable cognitive effects — on attention, memory and focus — that in some studies resemble accelerated aging. Science also suggests we have more control than we realize when it comes to reversing this damage, and the solution is surprisingly simple: Take a break... "Digital detoxes" can sound like a fad. But in one of the largest studies to date, published in PNAS Nexus and involving more than 467 participants with an average age of 32, even a short time away produced striking results — effectively erasing a decade of age-related cognitive decline.

For 14 days, participants used a commercially available app, Freedom, to block internet access on their phones. They were still allowed calls and text messages, essentially turning a smartphone into a dumb phone. Their time online decreased from 314 minutes to 161 minutes, and by the end of the period the participants had improvements in sustained attention, mental health as well as self-reported well-being. The improvement in sustained attention was about the same magnitude as 10 years of age-related decline, the researchers noted, and the effect of the intervention on depression symptoms was larger than antidepressants and similar to that of cognitive behavioral therapy.

But two things were even more mind-blowing... Even those people who cheated and broke the rules after a few days seemed to have positive effects from the break; and in follow-up reports after the two weeks, many people reported the positive effects lingered. "So you don't have to necessarily restrict yourself forever. Even taking a partial digital detox, even for a few days, seems to work," Kushlev said.
The article also notes a November study at Harvard published in JAMA Network Open where nearly 400 people 'found that even a short break can make a measurable difference: After just one week of reduced smartphone use, participants reported drops in anxiety (16.1 percent), depression (24.8 percent) and insomnia (14.5 percent)..."

"Other experiments point in the same direction — whether decreasing social media use by an hour a day for one week or stepping away from just Facebook and Instagram."

Bruce66423 shares a report from the Guardian: The European parliament has blocked the extension of a law that permits big tech firms to scan for child sexual exploitation on their platforms, creating a legal gap that child safety experts say will lead to crimes going undetected. The law, which was a carve-out of the EU Privacy Act, was put in place in 2021 as a temporary measure allowing companies to use automated detection technologies to scan messages for harms, including child sexual abuse material (CSAM), grooming and sextortion. However, it expired on April 3, and the EU parliament decided not to vote to extend it, amid privacy concerns from some lawmakers.

The regulatory gap has created uncertainty for big tech companies, because while scanning for harms on their platforms is now illegal, they still remain liable to remove any illegal content hosted on their platforms under a different law, the Digital Services Act. Google, Meta, Snap and Microsoft said they would continue to voluntarily scan their platforms for CSAM, in a joint statement posted on a Google blog. Bruce66423 adds: "Child abuse as the excuse for avoiding privacy protections. Who would have thought it?"

Microsoft has started stripping Copilot branding out of Notepad in Windows 11, replacing the old Copilot menu with a more generic "writing tools" label. The AI features themselves aren't going away, but Microsoft seems to be backing off the heavy-handed Copilot branding and extra entry points. Windows Central reports: As promised, Microsoft is now beginning its effort to reduce and remove Copilot branding across Windows 11, with the latest Notepad update for Insiders outright removing the Copilot icon and phrasing. Now, the AI menu is simply called "writing tools," and maintains the same functionality as before. Additionally, Microsoft has also removed references to AI in the Settings area in Notepad. Now, the ability to turn on or off these AI powered writing tools are now listed under "Advanced features."

This change is present in the latest preview build of Notepad which is now rolling out to all Windows Insiders. The app version is 11.2512.28.0, and you'll know you have it if you see the Copilot icon replaced with a pen icon instead. [...] For Notepad, it appears Microsoft has opted to replace the Copilot menu with something more generic. It's still the same functionally, but it's no longer leaning on the tainted Copilot brand. Of course, you can still easily turn off all AI features in Notepad if you don't want them. The Verge reports that the "unnecessary Copilot buttons" are also disappearing from the Snipping Tool, Photos, and Widgets.

Futurism found that Google News is surfacing Polymarket betting pages alongside traditional news sources. "The bets often appear in the 'For you' section of Google News, which is tailored to a user's personal interests," the publication reports. "In one instance, it was even the very top result, as with this bet on the price of Bitcoin." From the report: In our testing, Polymarket bets are also showing up on the Google News home page. But links from the prediction market can pop up all over Google News, including in searches. In further tests, looking up "will ships transit the strait," referring to the Strait of Hormuz, returned numerous credible sources like Financial Times, The Guardian, and Reuters. Just below them, however, was a Polymarket bet on the number of ships that would be allowed to pass through the critical oil passageway.

This doesn't appear to be an accident. When searching "Polymarket" in its search bar, Google News now allows users to choose it as a "source," directing them to a page that aggregates other Polymarket hits. It's not the only non-news site that's selectable as a source -- looking up "Reddit" and "X" offers the option, too -- but searching for "Kalshi," another prediction market and Polymarket's main competitor, doesn't give the option to use it as a source. [...] In light of all this, Polymarket appearing in Google News is a major victory for the prediction platform -- rubber-stamping its image as an authority on developing real-world events right alongside genuine real publishers of journalism.

Gmail's end-to-end encryption is now available on all Android and iOS devices, letting enterprise users send and read encrypted emails directly in the app without any extra tools. "This launch combines the highest level of privacy and data encryption with a user-friendly experience for all users, enabling simple encrypted email for all customers from small businesses to enterprises and public sector," Google announced in a blog post. BleepingComputer reports: Starting this week, encrypted messages will be delivered as regular emails to Gmail recipients' inboxes if they use the Gmail app. Recipients who don't have the Gmail mobile app and use other email services can read them in a web browser, regardless of the device and service they're using.

[...] This feature is now available for all client-side encryption (CSE) users with Enterprise Plus licenses and the Assured Controls or Assured Controls Plus add-on after admins enable the Android and iOS clients in the CSE admin interface via the Admin Console. Gmail's end-to-end encryption (E2EE) feature is powered by the client-side encryption (CSE) technical control, which allows Google Workspace organizations to use encryption keys they control and are stored outside Google's servers to protect sensitive documents and emails.

France says it plans to move some government computers from Windows to Linux as part of a broader push for digital sovereignty and reduced dependence on U.S. technology. TechCrunch reports: In a statement, French minister David Amiel said (translated) that the effort was to "regain control of our digital destiny" by relying less on U.S. tech companies. Amiel said that the French government can no longer accept that it doesn't have control over its data and digital infrastructure. The French government did not provide a specific timeline for the switchover, or which distributions it was considering. Microsoft did not immediately comment on the news.

[...] France's decision to ditch Windows comes months after the government announced it would stop using Microsoft Teams for video conferencing in favor of French-made Visio, a tool based on the open source end-to-end encrypted video meeting tool Jitsi. The French government said it also plans to migrate its health data platform to a new trusted platform by the end of the year.

An anonymous reader quotes a report from The Drive: An auto dealer software company is pitching AI-powered kiosks designed to replace car salesmen on showroom floors. Automotive News says the industry is "skeptical." But be honest -- would you really rather deal with the average car lot shark than a computer?

Epikar, a South Korean company that cooks up digital management solutions for car dealers, has named its new AI invention the Pikar Genie. The idea is that customers can talk to this device, ask it product questions, and basically do everything you'd do with a car salesman except for actually closing the deal and signing paperwork. Renault, BMW, and Volvo are already using some Epikar products at South Korean dealerships, but this new customer-facing AI product is still in its infancy.

AN reported that "Renault assigns three salespeople to its Seoul showroom enhanced with Epikar automation compared with six for other Renault showrooms in South Korea," according to Epikar CEO Bosuk Han. The company's now looking to expand into America and is apparently already testing its products at at least one dealership stateside. Car-dealer consultant Fleming Ford (Director of Strategic Growth at NCM Associates) said U.S. dealerships "aren't ready for fully automated showrooms."

"The showroom isn't just where you buy a car," Automotive News quoted him saying. "It's where you decide who to trust to help you to choose the right car."

Meta has started removing ads from law firms seeking clients for social media addiction lawsuits, just weeks after a jury found Meta and YouTube negligent in a landmark case involving harm to a young user. "Lawyers across the country now are seeking new plaintiffs, in the hopes of bringing a class action lawsuit that could result in lucrative verdicts," reports Axios. From the report: Axios has identified more than a dozen such ads that were deactivated today, some of which came from large national firms like Morgan & Morgan and Sokolove Law. Almost all of them ran on both Facebook and Instagram. Some also appeared on Threads and Messenger, plus Meta's Audience Network -- which distributes ads to thousands of third-party sites.

One such ad read: "Anxiety. Depression. Withdrawal. Self-harm. These aren't just teenage phases -- they're symptoms linked to social media addiction in children. Platforms knew this and kept targeting kids anyway." A few of the ads still remain active, including some that were posted earlier today. "We're actively defending ourselves against these lawsuits and are removing ads that attempt to recruit plaintiffs for them," a Meta spokesperson said in a statement. "We will not allow trial lawyers to profit from our platforms while simultaneously claiming they are harmful."
