  • To Enforce Its Proposed Social Media Ban for 450 Million Pre-Teens, EU Builds an Open Source App
    by EditorDavid on 20/09/2026 at 11:34 am

    The European Commission "proposed on Thursday banning children under 13 from social media, with parent-supervised accounts until 15," reports Reuters. "Enforcement would rely on a tool Brussels built itself" — a free, open-source age verification smartphone app "that tells a platform whether a user meets an age threshold without revealing their identity..." If passed, the proposed Kids Act would create the world's largest social media access restriction, covering 450 million people across 27 countries... [The EU-built age-verification app] is being rolled out through member states, with seven pilot countries: Cyprus, Denmark, France, Greece, Ireland, Italy and Spain. The Commission expects EU-wide availability by the end of 2026. It will also be used to prove users are over 18 when accessing adult sites, a restriction already implemented under the Digital Services Act... [T]he system itself is decentralised. Member states run it through issuers they designate, and the proofs live on the user's phone. There is no central EU database of ages or of who verified whom... A user proves their age once to a nationally designated issuer — a body vetted by the member state, which can be a digital ID provider, a bank or a post office. At a restricted site, the app certifies that the user is above the required age threshold. The platform receives only a yes-or-no response. Issuance and verification are handled by separate entities. The proof provider is not told which service the proof was used for. Each proof works only once, preventing cross-service tracking. No identity documents or biometric data are retained. The code is open-source, allowing independent scrutiny. The significance of the EU approach is that it provides a common age-verification mechanism rather than leaving individual platforms to develop and enforce their own systems. "Online platforms can easily rely on our age verification app. So there are no more excuses," [EU Commission President Ursula] von der Leyen said... The proposal must be approved by EU member states and the European Parliament before becoming law. Non-compliance would risk fines of up to 6% of a tech company's global annual sales, plus supervisory fees, Reuters reported earlier. The EU's plan follows similar initiatives in Australia, Britain, China, India, Turkey and several European Union countries. Read more of this story at Slashdot.

  • Tech Industry Scratches Its Head Over Trump's 'AI Force' Proposal
    by EditorDavid on 20/09/2026 at 7:04 am

    Saturday morning President Trump announced he's creating an AI task force and appointing an AI czar, reports Politico. "I am forming the AI Force, much like I did Space Force, which has been a tremendous SUCCESS," Trump wrote Saturday in what Politico earlier described as "a lengthy Truth Social post on Saturday morning." TRUMP: Over the years, there have been many Hoaxes, all generated by the Radical Left Dumocrats, for purposes of destroying our Country. RUSSIA, RUSSIA, RUSSIA, UKRAINE, UKRAINE, UKRAINE, Global Warming, Impeachment Hoax #1, Impeachment Hoax #2 [...] and now, the decimation, or destruction, of AI, commonly known as Artificial Intelligence — And I, as President of the United States, will not stand by and let this happen. It all began with an attack on our Data Centers, until people realized how wealthy and prestigious they were for the Communities in which they were built. Higher Salaries, Lower Taxes, and Safer Streets, was the result, and the crazed Data Center attack has largely failed, so now [...] they are going straight at AI. We will not in any way hinder or stifle the Growth of this incredible Industry. Rather, we will cherish it, help it, and watch over it, as it grows! However, we will also be looking for BAD, and we can do that, very easily, with our already existing Criminal and Civil Justice System. For this purpose, I am forming the AI Force, much like I did Space Force, which has been a tremendous SUCCESS, in my First Term. To that end, I will be announcing, in the near future, the AI "Czar" — Only High I.Q. individuals need apply! Trump concluded by saying AI "is the next Industrial Revolution, or Internet, but will be even larger and more impactful... We are leading China, and the rest of the World, and I intend to keep it that way!" But what exactly is AI Force? "The White House did not immediately respond to a request to clarify whether the agency would be military or civilian," notes the Washington Post. So now "The tech industry is struggling to make sense of President Donald Trump's surprise announcement," Politico reported Saturday afternoon: Four representatives for the sector, who were granted anonymity because they were not authorized to speak publicly, told POLITICO that the industry was not widely informed of Trump's decision prior to the Truth Social post. "Nobody knows what the idea even is," one of the people said. Another said that feedback on the idea was not widely solicited within the industry. The White House did not immediately respond to a request for comment... "I think that he clearly feels pressure to say something, but he's torn because he's just spent the last few days saying that the whole thing is a hoax," Adam Kovacevich, CEO of the progressive tech industry coalition Chamber of Progress, said of Trump and his prior dismissal of AI doomsday scenarios. Since the departure of David Sacks, who stepped down as the Trump administration's previous AI czar earlier this year, the White House has been "making up AI policy as it goes," Kovacevich added. "I think it's clear they've really missed the presence of an organized leader like David Sacks was." One of the tech industry representatives said they were confused about whether the task force would be charged with formulating more AI regulations or recommending policies that would further stimulate the tech's development. Taylor Barkley, director of federal government affairs at the industry-aligned Abundance Institute, is eyeing it as a way to solidify a light-touch government approach to the technology he says will foster innovation. "Any AI Force or AI Czar should have one job: keep the field open so entrepreneurs at every scale can compete, free from onerous regulation," he told POLITICO. "Existing criminal and civil law can handle bad actors. New permission regimes will stifle the very activity America needs most." It's worth noting that the day before, California's governor made an announcement. "With Donald Trump and Congress asleep at the wheel, Governor Gavin Newsom is once again taking the lead to strengthen AI safety for all Americans," the governor's office announced Friday. Newsom issued a strong executive order convening experts to help California create new AI safety laws and reporting rules, possibly even requiring safety auditors embedded in labs and emergency "kill switches" in frontier models.

  • Customer-Losing Flock Now Offers Buyouts to Avoid Laying Off Employees
    by EditorDavid on 20/09/2026 at 2:34 am

    Mashable writes: Flock Safety offered employees voluntary buyouts on Friday, WIRED reported... Without the buyouts, those familiar with the situation suspect the company would have to lay off some of its 1,500 employees. WIRED writes that people familiar with the program "say they believe that a significant number of the startup's roughly 1,500 employees may try to depart." Flock is making the severance offers as it continues to lose customers... The company has had many of its contracts either not extended or dropped this year, which could leave it short of revenue goals, according to two of the people. A wave of vandalism targeting its cameras has unexpectedly increased expenses. Without buyouts, Flock almost certainly would have to lay off some staff, one of the people believes... People familiar with Flock's severance plan tell WIRED that some employees may take the offer amid speculation that the company, which has raised about $1.2 billion in venture capital, might resort to selling off parts or all of its business to stay afloat... One advocacy group identified 93 city and county governments that cut ties with Flock in August alone. Overall in 2026, roughly three times as many local governments have dropped Flock compared to the previous five years. Flock has recently been building products that extend the company beyond its core license plate reader offering. WIRED reported last month that the company has developed AI-powered investigative software to identify drivers, find potential associates based on patterns of movement, and search across police records and other data. A separate WIRED analysis of Flock's software found tools designed to continuously search camera feeds for people matching written descriptions. WIRED's analysis of Flock's code also found potential integrations with drones and other surveillance systems. Flock's financial scrambles might explain an incident in Syracuse, New York. The nonprofit news site Central Current discovered the city's contract said its license plate data wouldn't be shared outside the police department, reports Mashable: But the department had granted access to other agencies, which police said was an accident. Over roughly a year, searches by officers around the country reached Syracuse's data nearly 4.4 million times. And that wasn't the only surprise in the paperwork. Central Current also found that Flock could keep using Syracuse data after the contract ended. When the city approved cameras from Axon to replace Flock's, Flock said Syracuse couldn't simply end its agreement early. It warned that the city might have to pay for both systems; so even as officials moved to replace the cameras, they faced questions about what Flock could do with the data and what the city might still owe. Meanwhile, the Texas Department of Transportation "has stopped issuing permits allowing Flock cameras and other automated license plate readers to be installed along state roads..." reports the Texas Tribune. "There were an estimated 13,000 Flock cameras across Texas in August, but hundreds of the devices have been shut down after [governor] Abbott's funding freeze." And in August Florida's Republican Governor "ordered his state's transportation department to remove the cameras from state roads, saying he didn't want 'a surveillance state.'"

  • Developer Abandons 'PS5 Linux' Project After Sony Patches AI-Discovered Exploit
    by EditorDavid on 19/09/2026 at 10:05 pm

    "In April this year, we saw Andy Nguyen turning the PS5 into a Linux-powered gaming PC," writes the blog It's FOSS. It ran Steam games and emulators using the PS5's on-board hardware. But this week Andy announced he's "stopping all my work on PS5 Linux" and "stepping away from the PS5 scene." stopping work on porting the project to the PS5 Pro, which would've shipped sometime in 2027. Andy Nguyen: After pouring my heart and months of my life into it, including plans to finish PS5 Pro support and release in 2027, it's all down the sink. The scene used to be a group of highly talented researchers, but now it is just a bunch of noobs using LLMs and writing hacks they don't even understand. Slop kiddies found the only hypervisor bug left, which I had also found a while ago, and decided to report to Sony. I asked them to at least wait for GTA 6 to come out so that people would have the opportunity to legally purchase the game and also enjoy Linux. They agreed to wait, but not a day passed and they decided to waste it instead. Or, as It's FOSS tells it: Running Linux on a PlayStation console is possible because the PS5 Linux project was able to find a way past the hypervisor using exploits Sony had already patched, covering firmware 3.00 through 7.61. .. [The bug's discoverer writes it was] found with what he calls his "trusty ai clanker machine" and no help from anyone else. He had even agreed to Andy's request to not disclose the findings. Unexpectedly, a third person, still unnamed, found the same bug using AI a few hours later. Anticipating that there would be more people finding the same bug, [he] decided to post the flaw on HackerOne. The project's GitHub page and all the related repositories are still there. Nothing has been archived as of today, and if you wanted to, you could start contributing to the PS5 Linux project by taking over any pending work or cooking up new improvements... The PS5 Pro support Andy was building never reached the repository, so you would have to start from scratch... While Andy's departure is a blow to the plan for supporting newer PS5 firmware and the PS5 Pro, other contributors have shown that they can deliver work on the loader without him, and I am hopeful more will follow.

  • Fake AI Intelligence Almost Made the US Military Start a War With China
    by EditorDavid on 19/09/2026 at 5:34 pm

    U.S. military intelligence received an inaccurate report this spring that a Chinese ship in the Middle East was transporting components of a nuclear weapons program, reports CNN. "The US military swung into action with plans to intercept the vessel, according to four sources familiar with the episode." Armed members of the US military were preparing to board the ship [according to two of the sources]. Military planes were in the air, one of those sources and another source familiar with the incident said. It was only just before the planned operation that officials dug deeper into the report put together by a special operations command analyst and found it had been generated with the help of AI — and that a chatbot the analyst had used inaccurately identified the material the ship was carrying. The report, according to one of the sources, was "entirely false." But it also "almost started a war," the source said. Any US operation against a Chinese vessel could have risked spiraling into an armed conflict between the two nations. Across the US military and the intelligence community, officials are pushing to weave AI into nearly every facet of their work, from analyzing the huge volumes of raw intelligence the US collects and selecting targets for strikes, to more mundane applications like managing budgeting, logistics and supply chains. But the episode underscores the profound risks of using this powerful, new and relatively poorly understood technology for targeting in the middle of a war... Officials say the US can't afford to fall behind in integrating AI in case it must one day fight China or another adversary who would potentially be able to stay one step ahead of the US. In January, Defense Secretary Pete Hegseth released his agency's "Artificial Intelligence Acceleration Strategy" in a bid to speed up the military's use of AI. "We will unleash experimentation, eliminate bureaucratic barriers, focus our investments and demonstrate the execution approach needed to ensure we lead in military AI," Hegseth said in a speech announcing the strategy.

  • US Air Force F-16 Crashes in Michigan After Pentagon Orders More Flyovers
    by EditorDavid on 19/09/2026 at 1:04 pm

    The F-16 "experienced an incident," the Texas Military Department said in a statement, adding that "The pilot successfully ejected the aircraft and is receiving care at a nearby hospital." ABC News reports: A Texas Air National Guard F-16 crashed in Michigan during a training mission on Thursday afternoon, sparking an hourslong evacuation near the crash site, according to officials. The incident prompted the evacuation of homes and businesses within 1 mile of the crash site due to a "hazardous chemical spill related to the plane crash," Michigan State Police said... All of the Texas Air National Guard aircraft that were in Michigan for the training were immediately grounded, and will likely remain so for the next 24 hours, according to a U.S. official. America's War Department has said it wanted to see more military flyovers writes The Daily Beast, adding that the F-16 "was due to perform a flyover at a high-school football game on Friday night, the Alpena News reported." The military said it was still investigating the cause of the crash, but one pilot told air traffic controllers that he believes his wingman hit a bird before the crash.... The accident followed a Pentagon X post on Thursday after widespread criticism of low-altitude flyovers and maneuvers. "The flyovers will continue until morale improves," it said.
