  • World's First Wave Power Generator Receives Certification For Regular Use
    by BeauHD on 24/07/2026 at 7:00 am

    "The Norwegian certification agency DNV has certified the commercial wave-driven power generator Corpower C4 for regular use," writes Longtime Slashdot reader Qbertino. "German news site heise.de has a detailed write-up. See a CGI video of the power station and its internals, as well as the company's website [at their respective links]." From the report (translated to English): According to the manufacturer Corpower Ocean, it is the first DNV prototype certificate for a wave energy converter. The certificate confirms that Corpower's technology meets DNV's requirements for structural strength, reliability, and safety, Corpower Ocean announced. The certification process began in the design phase and lasted seven years. DNV oversaw the process from concept development through design, manufacturing, and assembly, to dry-running tests and subsequent operation. This is an important step, said Patrik Moller, CEO and one of the founders of Corpower Ocean. With the certification, wave energy is no longer just a promising technology, but a proven and financially viable one. This opens up new opportunities for project financing, insurance, and investments in commercial applications. The Corpower C4 wave power plant looks like a normal buoy: It consists of a 19-meter-long floating body with a diameter of 9 meters and a weight of approximately 11 tons. The system is anchored to the seabed. A mechanism inside the buoy converts its up-and-down movements in the waves into a rotary motion. This, in turn, drives a generator that produces electricity. The report notes that the company is "planning the first two industrial-scale wave energy farms off the coasts of Portugal and Scotland," which are scheduled to begin operating sometime between 2027 and 2029.

  • Google Adds Selfie Video As a Log-In Option
    by BeauHD on 24/07/2026 at 3:30 am

    An anonymous reader quotes a report from Engadget: You'll now be able to use selfie videos to log into your Google account. It has long been possible to log into Google using your face, via your phone's face unlock or if your passkey login uses biometrics for verification. This is yet another option to get into your account using your face to authenticate your identity, which could be especially useful if you don't have access to the phone or computer you typically use or if you got locked out of your account and none of the other log-in options are working. [...] Google will ask you to turn your head in certain ways during the verification and every time you use the option to log in. The company says it's to fend off impersonation attempts, such as deepfake videos, and prove you're currently in front of the camera. It will, of course, have to save your selfie video and use it for comparison for future logins.The company says it will encrypt your video and only use to help you sign in, but if you ever change your mind, you can delete it from your Google account. It's worth noting the option is currently unavailable for Workspace accounts, child accounts and those enrolled in Google's Advanced Protection Program. You can set it up and give it a try at g.co/signin-selfie. Read more of this story at Slashdot.

  • Oracle Signs 10-Year Software Contract With Pentagon Worth Up To $7 Billion
    by BeauHD on 23/07/2026 at 11:00 pm

    Oracle has signed a 10-year Pentagon contract worth up to $7 billion to provide on-premises software, licenses, maintenance, and consulting for branches of the military. CNBC reports: The contract covers the use of Oracle software in on-premises data centers for branches of the military, the U.S. intelligence community and the Coast Guard, according to a statement. The Central Intelligence Agency was Oracle's first customer. A five-year base period for the contract includes perpetual and subscription-based software licenses, maintenance and consulting, according to one description. Kirsten Davies, the Department of Defense's chief information officer, said in the release that the agency is saving at least $441 million for taxpayers "by fundamentally improving how we procure on-premises Oracle capabilities."

  • Microsoft Responds to LG Monitors Installing McAfee Ads On Windows
    by BeauHD on 23/07/2026 at 10:00 pm

    LG is removing a McAfee pop-up ad from its LG Monitor App Installer after criticism that some LG monitors were silently installing the app through Windows Update and showing ads on every boot. Microsoft says LG agreed to disable the McAfee pop-up, but the broader issue remains: Windows allows certain peripheral companion apps to install automatically without notifying users. Ars Technica reports: Following Gamers Nexus' video, a Microsoft representative stated that the LG Monitor App Installer will no longer show pop-up ads for McAfee. In response to a social media post about the app, Pavan Davuluri, EVP of Windows and devices at Microsoft, said this week: "We've connected with the team at LG and as an immediate next step, they have agreed to disable the McAfee pop-up from their app. We appreciate LG working with us toward a shared goal of a better experience for our mutual customers. We will keep improving here with our ecosystem partners." As mentioned, some LG monitors appear to have been installing LG Monitor App Installer onto Windows computers for months. Publication Windows Latest noted that the app recently got an update, "and its changelog mentions McAfee as an additional app," which could be what prompted more people to see the ads... and then complain about them. However, the removal of McAfee doesn't address the problem of a peripheral installing ad-pushing software onto people's computers. Users have been finding LG Monitor App Installer and its ads on their systems without LG ever showing a prompt or asking for permission. LG has some of the most expensive computer monitors available. Paying, in some cases, over $1,000 for a monitor that ends up forcing ads onto Windows is disruptive and a privacy concern. Once the app is installed, "LG technically possesses permission to use 'all system resources,'" as well as to "collect geolocation, device data, online activity, contacts, user credentials, transactions, and more," [editor-in-chief of Gamers Nexus, Steve Burke] said.

  • EU Fines Google $1 Billion For Breaking Digital Antitrust Regulations
    by BeauHD on 23/07/2026 at 9:00 pm

    The European Union fined Google more than $1 billion for allegedly using Google Play and Search to steer users toward its own services and apps at the expense of competitors. The Associated Press reports: Google had recently lost its appeal of a $4.5 billion antitrust fine imposed by the EU for throttling competition and reducing consumer choice through the dominance of its mobile Android operating system. The European Commission, the bloc's executive branch and highest antitrust enforcer, said it was acting in the interest of consumers after an investigation of Google. "The best products should succeed because they're better, not because they're owned by the company running the search engine. And European consumers have a right to be told by app developers where to sign up to the best offers, even when the app store owner does not get a cut," said Teresa Ribera, the commission's Executive Vice President for Clean, Just and Competitive Transition. Google's President of Global Affairs Kent Walker blasted the fine as "product degradation driven by a small group of self-serving complainants" that will have a negative impact on European businesses and consumers. He said that the EU's Digital Markets Act forces Google "to strip away real-time search features Europeans love -- like instant pricing and direct availability for hotels, flights, and restaurants -- and dismantle safety protections on Google Play."

  • Amazon Is Bringing Games to Prime Video
    by BeauHD on 23/07/2026 at 8:00 pm

    Amazon is integrating its Luna cloud gaming service into Prime Video, adding a new "Games" tab where Prime members can play titles like "Hogwarts Legacy," "EA Sports FC 26," "Indiana Jones and the Great Circle," "Clue," and "Taboo." The games will be available starting today on Fire TVs in the U.S. and U.K., with additional supported devices and countries in the coming months. TechCrunch reports: With this move, Amazon is hoping games can turn Prime Video into a one-stop entertainment destination, borrowing a strategy from Netflix, which has increasingly embraced party games over the past several years. Since Amazon already operates a gaming service, it makes sense for the tech giant to integrate it into its streaming platform. [...] Amazon says its vision is to remove the barriers to gaming and make it accessible to anyone regardless of their experience or budget. The tech giant says Luna is designed to bring gaming to a much broader audience by removing the need for expensive consoles or gaming PCs and making games as easy to access as movies or TV shows.
