  • Taiwan 'Throttles' Mobile Internet For First Time During Annual War Games
    by BeauHD on 10/08/2026 at 5:00 pm

    Taiwan deliberately throttled mobile internet across the Taichung area during its annual Han Kuang war games, "simulating communication disruption in the event of a Chinese attack or natural disaster," reports Reuters. The drill accompanied air-raid exercises and military rehearsals aimed at defending strategically important areas such as the Penghu Islands. From the report: Democratically governed Taiwan, which China claims as its own territory, has long lived with the threat of a Chinese invasion and holds air raid drills along with its war games every year, clearing people from the streets for 30 minutes. During the internet "throttling" drill, centered on Monday on the major central metropolis of Taichung, only basic mobile phone services worked, though other functions including ATMs, traffic signals, landlines and fixed internet services were not affected. Air raid sirens rang out in Taichung "and people cleared the streets from 2:30 p.m. (0630 GMT) as the government sent simultaneous text messages in Chinese and English telling mobile phone users of "simulated air attacks on communication infrastructure." The government had widely flagged the drill ahead of time, including posting details on social media, and most people Reuters spoke to at the Taichung train station were prepared. [...] The same exercise will be repeated on Thursday in northern Taiwan, including the capital Taipei. Read more of this story at Slashdot.

  • AI Assistant Hacks Gym Website In First Known Australian Autonomous Cyber Attack
    by BeauHD on 10/08/2026 at 4:00 pm

    An anonymous reader quotes a report from ABC News & Headlines: Andrew asked his personal assistant to book him a spot in one of his gym's coveted morning classes. It was a task he thought was well suited to this particular assistant because the booking form was online and because his assistant was not a person -- it was artificial intelligence (AI). But Andrew was shocked by what happened next. His AI assistant found a way to book the gym class months further in advance than the gym allowed, thanks to a vulnerability it discovered in the booking software. Then it went further, kicking someone out of the waiting list who was ahead of Andrew -- something it was not asked to do. The accidental hack is the first known Australian case of an emerging risk from a new generation of AI capable of behaving in unexpected ways. Read more of this story at Slashdot.

  • Paramount Promises 30 Film-A-Year Contracts After WBD Acquisition
    by BeauHD on 10/08/2026 at 3:00 pm

    Paramount is making commitments to major theater chains to release 30 films annually for three years if its Warner Bros. deal goes through. According to Deadline, the written commitment was sent to "at least one of the top two circuits" (specifically Regal but AMC may have also received a written commitment) and includes "an exclusive 45-day theatrical window and a 90-day window to streaming." From the report: When it comes to the big chains, it matters for them to be on the right side of history with Paramount, especially when it comes to future terms on a 30-film slate. However, the rest of Cinema United (formerly National Association of Theatre Owners) remains firmly against the Paramount-Warner Bros merger and its potential negative financial outcomes in regards to long-term box office, feature film output and loss of jobs. Cinema United has been trying to meet again with Paramount CEO David Ellison, but there's nothing on the books yet, we understand. [Regal boss Eduardo Acuna] told Deadline that in regards to Paramount's future promise to exhibition, "[Paramount CEO] David [Ellison] is sincere in making these commitments, and he has offered to execute a consent decree to the state AGs to that effect. These are tangible and important commitments that will benefit the industry and which can be measured." Paramount insiders tell us that no written commitments have been given to exhibitors yet, but Ellison is willing to make non-bespoke ones to any theater chain wanting them. And such deals will come with financial penalties to Paramount should it break such agreements with theaters. Again, this is all about Ellison standing behind his promises made at CinemaCon to maintain a hefty theatrical output and excellent windows to theaters. Read more of this story at Slashdot.

  • Toxic Underground Fires Are Spreading at California Landfills
    by EditorDavid on 10/08/2026 at 11:34 am

    Three years ago environmental regulators discovered garbage burning deep inside California's Chiquita Canyon Landfill, reports the Los Angeles Times. [Alternate URL here.] "Few imagined the calamity that would follow. "Somehow the landfill's pollution control system introduced oxygen below, causing decades-old waste to rapidly decompose, generating intense heat and eventually widespread smoldering, federal and state environmental agencies say." The broiling temperatures released toxic gases and hazardous liquid waste that bubbled up to the surface. Residents living in the nearby communities of Val Verde and Castaic have phoned in thousands of complaints about stench and lived with nausea, dizziness and trouble breathing. The underground fire has tripled in size since first confirmed in 2023. Recently a towering mound of landfill garbage perched on the hillside has warped and threatens to trigger an avalanche of garbage and chemical-filled liquid, or leachate, according to the California water board... At first, local officials described the problem in Los Angeles County at Chiquita Canyon landfill as a rare, even unprecedented disaster. But since then, California regulators have learned that at least two other landfills are wrestling with high temperatures and similar conditions. Scorching temperatures have overtaken at least 30 acres of El Sobrante landfill near Corona in Riverside County. Excessive heat and emissions have also been detected at Avenal landfill in the San Joaquin Valley. The discoveries raise an unsettling question: How many landfills are dealing with these disasters? Are they a broader problem in California...? Chiquita Canyon closed at the end of the 2024 and stopped accepting new garbage. But the fire is expected to last for years as it continues to consume decades-old trash. "Underground landfill fires are complex, nearly impossible to extinguish once they break out," according to the article. "As regulators search for a solution, residents find themselves struggling with the wait." Some residents have worn gas masks — or sold their homes. Read more of this story at Slashdot.

  • How Accurate Are Flock's AI-Powered License-Reading Cameras?
    by EditorDavid on 10/08/2026 at 7:34 am

    Futurism reports: 404 Media revealed that a July 10 audit by the Los Angeles Police Department Office of the Inspector General caught the department's ALPR cameras generating 161 false stolen-vehicle alerts in just two months — each one ending with officers pulling over an innocent driver. Factoring in 337 alerts which "resulted in the recovery of stolen vehicles," the LAPD's cameras carry an error rate of 32.3 percent, effectively giving officers a one-in-three chance at pulling an innocent person over. "The biggest issue remains this national database at the FBI called NCIC," Flock's CEO Garrett Langley recently told The Drive, complaining about "how archaic its structure is." Flock CEO: There's no feedback loop mechanisms; it's really just a static comma-separated file. We've tried to build around it. We have this concept called "suppression." A local agency — let's take Atlanta, where I live — might see that there's a stolen plate out of California, but it's already been resolved because it's a rental car or a dealer car. They can, in Flock, suppress that: "Never alert us on that for the next year." That's to get around the fact that they can't force another agency to remove it from NCIC. Ideally, the way it would work is if enough agencies — let's call it one, two, or three — flag a tag as no longer valid or a bad entry, it should just get removed. Or at least it should get pushed more aggressively by the FBI... I'm hopeful that they'll see there's an opportunity to make something like NCIC, which is an important tool not just for companies like Flock, but for police departments to work together, start to make some enhancements to modernize what's a central part of our policing system. Later in the interview he says "It's less than one in a million alerts that an officer says, 'I'm not sure if that's right.' Less than one in a million." A recent report from Business Insider shares a worst-case scenario. In the summer of 2024 a Sacramento police officer said Flock's cameras had sent six false alerts for the same vehicle, wrongly saying it had been stolen or used in a felony crime in the nearby suburb of Roseville: Roseville police could see that Flock's software kept confusing the "9" on the man's license plate for an "8." The car owner said he would take off his license plate cover. Soon after, it happened again. It's "easier at this point we have it memorized," a dispatch supervisor in Roseville wrote in an email to a colleague. Flock says that in optimal conditions, its cameras accurately read more than 96% of license plate characters. Hundreds of pages of records from the Roseville Police Department show a different picture. In 2023 and 2024, Flock sent 1,427 alerts to Roseville police, flagging vehicles as stolen or used in a felony after they passed one of the city's Flock cameras. An analysis by the police department found that in 71% of those alerts, Flock's machine-learning software incorrectly read the license plates... The cameras regularly missed vehicles, captured blurry images, misread license plate characters and states, and sent delayed alerts to police about vehicles possibly connected to crimes, the records show... A factor that contributed to the misread problems in Roseville was the "particularly unique deployment" that the city requested, a Flock spokeswoman said. Roseville said it has its cameras configured so that they capture only the backs of vehicles, a setup intended to avoid capturing personally identifiable information like faces. Roseville's setup included older hardware and placement of cameras higher and further from vehicles than the company typically recommends, Flock added... In Toledo, Ohio, driver Brandon Upchurch was mauled by a police dog after a Flock camera misread the "7" on his license plate as a "2." As a result of his injuries, he said, he lost his job and was evicted from his home. He settled a lawsuit against the city and police officer for $35,000. None of the incorrect Flock alerts in Roseville resulted in a traffic stop or arrest, a department spokesman said. Roseville requires police officers to verify that a license plate is stolen or have independent reasonable suspicion of a crime before making a traffic stop... Flock said Roseville's camera performance has significantly improved, which the police department disputed... Flock's cameras also missed vehicles altogether... At one point, Flock's product director for machine learning suggested that officers ask drivers to remove license plate frames that made it "very difficult for the machine vision to tell it is actually a 'E' and not an 'F.'" Roseville told Flock at the time that it wouldn't do so, according to the department spokesman. Flock in 2024 shared an analysis with Roseville's police department, outlining reasons for the misreads. Vehicles far from a camera were sometimes blurry. Plates were cut off by trees or license plate frames. And Flock's software confused similar characters, mistaking an "N" for a "V", or a "1" for a "4...." Roseville isn't the first organization to flag inaccuracies in Flock's technology. In 2021, the research firm IPVM independently tested Flock's license plate readers, concluding that Flock misidentified the state in about one of 10 reads, and that the system regularly misclassified vehicles' type and make. IPVM said that Flock subsequently blocked it from purchasing its cameras for testing. Thanks to long-time Slashdot reader Cognitive Dissident for sharing the article.

  • Microsoft Responds to Outcry After Quietly Installing Beta 'Photos' App on Enterprise Machines
    by EditorDavid on 10/08/2026 at 4:34 am

    Microsoft's cloud storage app OneDrive got a new Photos app in the worst possible way, reports the blog Neowin . "The app is reportedly showing up even on Windows 11 Enterprise machines, despite apparently being a beta application aimed at consumer functionality." One admin questioned why a beta app was appearing on an Enterprise SKU in the first place, while another described the situation as yet another consumer-oriented feature being forced onto corporate PCs. Things get even more frustrating for IT departments because there does not appear to be a straightforward Microsoft-provided way to disable the app... Enterprise administrators generally need to know what is being installed on their managed devices, particularly when a software is labeled as beta. Quietly adding another application and leaving admins to clean it up themselves is therefore unlikely to win Microsoft many fans. But there's another problem, according to the blog Windows Latest. "OneDrive Photos automatically scans your system storage for photos," and apparently "doesn't need a Microsoft account to work, as it can also detect your local files." There's also a People section that groups similar faces in your photos. Microsoft asks for permission before turning it on and explicitly warns that facial data could be considered biometric data in some regions. The company says only you can see the grouped faces, that the data isn't shared with third parties, and that you can delete it by disabling the feature. In a statement to Neowin, Microsoft admitted this new photos "experience" they're "incubating" had gone "more broadly than it should have," and then promised that "We're fixing that." The spokesperson also said the Windows Photos app will "always give you the option of local and cloud photos" and, also a choice of whether or not to use it OneDrive." But there's another "awkward catch," notes the blog Digital Trends. "Users currently can't uninstall OneDrive Photos without removing the main OneDrive app too." Because OneDrive Photos is tied to the main OneDrive sync client, Windows 11 doesn't currently offer a separate uninstall option. The only straightforward way to get rid of OneDrive Photos right now is to uninstall OneDrive itself... Removing the main client can also affect its File Explorer integration and shortcuts... Microsoft says this will change. The company is working on controls that will let users remove OneDrive Photos separately from the main OneDrive app. On enterprise PCs managed through Intune, Microsoft says the app will automatically disappear where it isn't supported.
