  • Google Brings Its Age-Assurance Tech To Android Developers Worldwide
    by BeauHD on 30/07/2026 at 4:00 pm

    An anonymous reader quotes a report from TechCrunch: Google is expanding its answer to Apple's age-assurance tools with Wednesday's news that it will bring its Play Signal API to users worldwide by the end of 2026. The technology, already available in Brazil, allows Android developers to identify younger users of their apps in order to provide safer, age-appropriate experiences. The expansion will initially bring the API to Australia and Canada by mid-August, before rolling out globally to all markets by the end of the year. [...] Like Apple, Google's technology allows developers to obtain a user's age range without needing to access personal information, like their date of birth. Instead, it enables parents to share their child's age range directly with apps. It also lets adults share their age when prompted by app developers as well, allowing for customized experiences. Parents won't have to manage sharing this information on an app-by-app basis, either. To make it easier, Google centralizes these controls inside its parental controls dashboard, Family Link. Once entered, any developer that chooses to incorporate age-range information can access this signal to customize their apps accordingly. Google notes, however, that the age ranges are not shared by default -- parents must opt in by entering that information. The feature joins other safety tools on Google Play, including those that let developers restrict a child's ability to discover their apps. Parents, meanwhile, can continue to use Google Play's Family Link app to manage their child's screen-time limits, approve app downloads, or set PIN-based content filters for specific apps.

  • GCC Adopts Policy Rejecting Significant AI-Generated Code
    by BeauHD on 30/07/2026 at 3:00 pm

    GCC has adopted a policy rejecting substantial code contributions generated by or derived from LLMs. "This covers not just code copied directly from tools like ChatGPT, Gemini, or GitHub Copilot, but also any versions of the code later edited or rewritten by a human, provided that the final contribution is still based on material generated by the system," reports Linuxiac. From the report: The important point, then, is not whether a developer has used an AI tool at some stage in their work; contributors can use LLMs to discuss ideas, understand existing code, learn about a field they are unfamiliar with, or carry out general research. The limitation lies in the inclusion of copyright-significant material generated by such tools in the code submitted to GCC. The policy also provides for a few limited exceptions; GCC maintainers are allowed to accept changes that are legally insignificant or trivial and are generated by an LLM, on the condition that they meet the project's normal contribution requirements and the use of an LLM is clearly disclosed. Furthermore, copyright-significant AI-generated test cases could still be accepted. Since test cases usually involve small programs which are intended to reproduce compiler bugs or to verify certain behavior, the policy deals with them separately from code that is incorporated into GCC itself. It does not follow that merely looking at or altering the generated code makes it acceptable. By the rules that have been adopted, a contributor cannot take substantial implementation produced by an LLM, clean it up manually, and then treat the resulting patch as if it had been originally written by them. Once a contribution has been derived from generated content, it is still subject to the policy. Read more of this story at Slashdot.

  • Comcast Store Punished Low Sales By Smashing Pies In Workers' Faces, Lawsuit Claims
    by BeauHD on 30/07/2026 at 11:00 am

    A former Comcast retail employee alleges that a Connecticut store manager tied the lowest-performing salesperson to a chair each month and had co-workers smash a cream pie into their face, recording the incidents as a sales-motivation tactic. The plaintiff says he resigned after reporting the alleged assaults and is seeking damages for constructive discharge and emotional distress. Ars Technica reports: A Comcast store in Plainville, Connecticut, "had a policy that the highest-ranked Retail Sales Consultant for the prior month was instructed by his or her supervisor -- Ms. Peterson, the Comcast Store manager -- to tie the lowest-ranked sales consultant for the prior month to a chair in the back office and thereafter assault that person by violently smashing a cream pie in their face," the complaint alleged (PDF). Plaintiff David Figueroa's lawsuit said he was hired as a retail sales consultant on February 2, 2026, and was supervised by store manager Sully Fuentes Peterson. Figueroa alleges that Peterson "designed and implemented" the pie-in-face ritual to meet goals related to sales and positive responses in customer surveys. "Defendant did not inform the Plaintiff prior to his acceptance of Defendant's offer of employment that the Comcast Store has a policy of subjecting Retail Sales Consultants to public assaults by co-workers -- at the direction of Ms. Peterson, the store manager -- for the purpose of increasing Defendant's sales and profitability," the lawsuit said. Figueroa resigned on February 27, and he alleges it was a constructive discharge. The lawsuit says the defendant, Comcast, was negligent because it "reasonably should have known" about the store management's policies and that the policies could harm employees. Comcast "failed to properly supervise the Comcast Store's management team," allowing store management to humiliate employees "for the purpose of promoting the Defendant's revenues and profits," the lawsuit alleged. Comcast said in a statement: "The Company has zero tolerance for harassment, humiliation, or any behavior that compromises a respectful and safe workplace. This matter is in litigation so we will not comment on the specific allegations, other than to say that we disagree with the claims in the complaint and its characterization of the alleged events, and intend to fully respond through the legal process."

  • Qantas Plane Flies For More Than 24 Hours In Record-Breaking Flight
    by BeauHD on 30/07/2026 at 7:00 am

    Qantas completed a record-breaking 24-hour, 24-minute test flight from Melbourne to Toulouse on Tuesday. "The specially adapted A350-1000ULR airliner is due to debut with the Australian carrier's nonstop Sydney-London route from 2027," reports The Guardian. From the report: Tuesday's flight is thought to be the longest ever by a commercial plane, beating the previous record of 22 hours and 42 minutes set by a Boeing 777-200LR in 2005 between Hong Kong and London via the Pacific in 2005. Flight-tracking provider Flightradar24 said the trip was the second-most-tracked flight ever on its channels -- behind a 2022 flight carrying Queen Elizabeth II's coffin -- with more than 3.6 million people following its progress northwards via Canada. Qantas has ordered 12 modified A350-1000ULR aircraft, designed to connect Australia's east coast with London and New York in about 20 hours. Read more of this story at Slashdot.

  • AI Companies Are Recruiting Electricians and Carpenters By the Thousands
    by BeauHD on 30/07/2026 at 3:30 am

    An anonymous reader quotes a New York Times report on how AI companies are pouring money into training and recruiting electricians, carpenters, and other skilled tradespeople to build data centers: There is no parallel in American history for the boom underway in the construction of data centers, fueled by companies with functionally unlimited cash that are racing to supply skyrocketing demand for their A.I. models. The explosion has offset flagging activity in other sectors, like office construction, which never recovered after the pandemic. Housing has been depressed by high interest rates, and offshore wind felled by political opposition. Still, competition for labor -- never mind land and materials -- is starting to weigh on other parts of the industry. "There's no question the resources are very limited, so decisions to build one thing kind of drag from another," said Mario Iacobacci, who runs the construction and infrastructure advisory practice at Oxford Economics. Developers are paying a premium for workers, especially in the rural areas where they are building data centers. According to an analysis by Indeed, the job listings website, hourly installation and maintenance jobs at data centers pay 42 percent more than similar jobs in other fields. Behind that inflated pay is a bidding war. In markets with a lot of data center construction, like Dallas and Northern Virginia, workers can jump ship for bonuses or higher per diem rates. The competition has driven contractors to staffing services like Aerotek. "It is creating a labor tension that is really delicate," said Marty Schager, Aerotek's director of data center market development. "You've got a passive job-seeker community out there right now that I think is looking to potentially capture opportunity with this once-in-a-generation data center gold rush." [...] The question looms over the apprentices who will become journeymen as the build-out reaches fever pitch. Fully trained electricians could shift to nuclear plants, apartment buildings or pharmaceutical factories. But it's hard to imagine anything on the scale of what's underway. "The best-case scenario would be you train all these skilled workers up and right when the data centers start to become less popular is we'd have a housing boom," said Jeff Strohl, director of Georgetown University's Center on Education and the Workforce. "That's probably not likely." "If we have an influx of workers at this point with the data centers being built, what happens when they're done? Where do those workers go?" he said. "How many people does it take to run a data center after taking up all this property and all this land that could have been used for something else?" Read more of this story at Slashdot.

  • Who Wins and Who Loses After US Bans Foreign Robots?
    by BeauHD on 30/07/2026 at 12:00 am

    The FCC's ban on Chinese-made robots extends well beyond humanoids to quadrupeds, research platforms, and many robot vacuums from allied countries. Supporters call it a major boost for domestic robotics, but critics warn that cutting researchers and startups off from affordable foreign hardware could slow U.S. innovation instead. Ars Technica's Jeremy Hsu examines who stands to gain and who stands to lose from the prohibition: Such an import ban would apply to some of the most affordable robots primarily produced by Chinese companies, including Unitree's humanoid robots that are used by robotics labs and researchers for tasks such as experimental robot surgeries. US consumers would also likely lose access to the newest robot vacuum cleaners that are mainly manufactured by Chinese companies such as Roborock. But the ban also broadly applies to foreign-made robots produced by countries nominally allied to the United States, including Japan, South Korea, and Germany. [...] The ban on foreign-made robots could theoretically encourage more US and foreign companies to set up manufacturing facilities in the United States. There are already multiple companies racing to scale up production of humanoid robots in US factories, including Agility Robotics, 1X Technologies, and Figure AI. Tesla has been attempting to shift production away from older electric vehicle models and toward its Optimus humanoid robot. Boston Dynamics has already been making its Atlas humanoid robot, along with its four-legged Spot robot and wheeled Stretch robot, at its main facility in Waltham, Massachusetts. The US robotics company is also planning to massively scale up manufacturing of the Atlas robot under South Korea's Hyundai Motor Company, which gained full ownership of Boston Dynamics in July 2026. "This is one of the strongest technology-security actions in modern US history," wrote Evan Beard, CEO of Standard Bots, in a LinkedIn post. "The message is unambiguous: robotics is a technology America must lead and own -- and foreign-subsidized robots will not be allowed to unfairly dominate US robotics as they did solar." Similar praise came from Rush Doshi, director of the Initiative on China Strategy at the Council on Foreign Relations, who, in a social media post, described the FCC decision as "one of the most significant actions taken so far in support of the US robotics ecosystem." However, several robotics researchers and analysts interviewed by The Robot Report expressed skepticism about any potential boost to US competitiveness in robotics. Some even warned that the ban could prove counterproductive for US robotics efforts to develop humanoid robots. "In the near term, the measure could slow US physical AI innovation by cutting startups and researchers off from future low-cost Chinese platforms before comparable Western alternatives exist," said Georg Stieler, a global robotics advisor and managing director for Asia at Stieler Technology & Market Advisory, in an interview with The Robot Report. US domestic production of robots lags behind China in terms of mass manufacturing at lower cost, said Rueben Scriven, a senior analyst at Interact Analysis. "This announcement is more likely to inhibit the US humanoid robotics industry, as the presence of low-cost Chinese humanoid robots has been helping educate the US market through promotional and entertainment use cases -- an effect this policy risks undermining," Scriven told The Robot Report. The report notes that previous FCC bans have done little to help create competitive U.S. alternatives, with restrictions on Chinese drones instead prompting companies to sell barely disguised versions of DJI technology.
