  • Comcast Keeps Losing Customers Despite Price Guarantee, Unlimited Data
    by BeauHD on 30/01/2026 at 2:02 am

    Comcast's attempt to slow broadband customer losses still isn't stopping the bleeding as fiber and fixed wireless competition intensifies. In Q4 2025 alone, Comcast lost 181,000 broadband subscribers, even as it leans harder into wireless bundling and other business lines like Peacock and theme parks. Ars Technica reports: The Q4 net loss is more than the 176,000 loss predicted by analysts, although not as bad as the 199,000-customer loss that spurred [Comcast President Mike Cavanagh's] comment about Comcast "not winning in the marketplace" nine months ago. The Q4 2025 loss reported today is also worse than the 139,000-customer loss in Q4 2024 and the 34,000-customer loss in Q4 2023. "Subscriber losses were 181,000, as the early traction we are seeing from our new initiatives was more than offset by continued competitive intensity," Comcast CFO Jason Armstrong said during an earnings call today, according to a Motley Fool transcript. Comcast's residential broadband customers dropped to 28.72 million, while business broadband customers dropped to 2.54 million, for a total of 31.26 million. Armstrong said that average revenue per user grew 1.1 percent, "consistent with the deceleration that we had previewed reflecting our new go-to-market pricing, including lower everyday pricing and strong adoption of free wireless lines." Armstrong expects average revenue per user to continue growing slowly "for the next couple of quarters, driven by the absence of a rate increase, the impact from free wireless lines, and the ongoing migration of our base to simplified pricing." Comcast Connectivity & Platforms chief Steve Croney said the firm is facing "a more competitive environment from fiber" and continued competition from fixed wireless. "The market is going to remain intensely competitive," he said. Read more of this story at Slashdot.

  • Cory Doctorow On Tariffs and the DMCA In Canada
    by BeauHD on 30/01/2026 at 1:25 am

    Longtime Slashdot reader devnulljapan writes: In 2012, Canada passed anti-circumvention law Bill C-11, cut-and-pasted from the U.S. DMCA, in return for access to U.S. markets without tariffs. Trump has tariffed Canada anyway, so Cory Doctorow suggests it sounds like like a good idea to ditch Bill C-11 and turn Canada into a "Disenshittification Nation" and go into the business of "disenshittify[ing] America's defective tech exports." Some of the specific ways Canada could respond include legalize jailbreaking, allow alternative app stores/clients, force companies to offer repair tools, and open firmware that break monopoly lock-ins. Cory's pitch is equal parts economic strategy (capture the rents Big Tech extracts) and national security (reduce dependence on U.S. tech stacks that can be switched off or weaponized).

  • Linux Gaming Developers Join Forces To Form the Open Gaming Collective
    by BeauHD on 30/01/2026 at 12:45 am

    A group of Linux gaming-focused distros and developers have formed the Open Gaming Collective to pool work on shared components like kernels, input systems, and Valve tooling. The Verge reports: Universal Blue, developer of the gaming-focused Linux distribution Bazzite, announced on Wednesday that its helping to form the OGC with several other groups, which will collaborate on improvements to the Linux gaming ecosystem and âoecentralize efforts around critical components like kernel patches, input tooling, and essential gaming packages such as gamescope." The other founding members of the OGC include Nobara, ChimeraOS, Playtron, Fyra Labs, PikaOS, ShadowBlip, and Asus Linux. [...] It's worth noting that this will mean some changes to Bazzite, which is switching to the OGC kernel, replacing HHD with InputPlumber as its input framework, and integrating features like RGB and fan control into the Steam UI. Bazzite also added that, "We'll be sharing patches we've made to various Valve packages with the OGC and attempting to upstream everything we can." Read more of this story at Slashdot.

  • An AI Toy Exposed 50K Logs of Its Chats With Kids To Anyone With a Gmail Account
    by BeauHD on 30/01/2026 at 12:02 am

    An anonymous reader quotes a report from Wired: Earlier this month, Joseph Thacker's neighbor mentioned to him that she'd preordered a couple of stuffed dinosaur toys for her children. She'd chosen the toys, called Bondus, because they offered an AI chat feature that lets children talk to the toy like a kind of machine-learning-enabled imaginary friend. But she knew Thacker, a security researcher, had done work on AI risks for kids, and she was curious about his thoughts. So Thacker looked into it. With just a few minutes of work, he and a web security researcher friend named Joel Margolis made a startling discovery: Bondu's web-based portal, intended to allow parents to check on their children's conversations and for Bondu's staff to monitor the products' use and performance, also let anyone with a Gmail account access transcripts of virtually every conversation Bondu's child users have ever had with the toy. Without carrying out any actual hacking, simply by logging in with an arbitrary Google account, the two researchers immediately found themselves looking at children's private conversations, the pet names kids had given their Bondu, the likes and dislikes of the toys' toddler owners, their favorite snacks and dance moves. In total, Margolis and Thacker discovered that the data Bondu left unprotected -- accessible to anyone who logged in to the company's public-facing web console with their Google username -- included children's names, birth dates, family member names, "objectives" for the child chosen by a parent, and most disturbingly, detailed summaries and transcripts of every previous chat between the child and their Bondu, a toy practically designed to elicit intimate one-on-one conversation. More than 50,000 chat transcripts were accessible through the exposed web portal. When the researchers alerted Bondu about the findings, the company acted to take down the console within minutes and relaunched it the next day with proper authentication measures. "We take user privacy seriously and are committed to protecting user data," Bondu CEO Fateen Anam Rafid said in his statement. "We have communicated with all active users about our security protocols and continue to strengthen our systems with new protections," as well as hiring a security firm to validate its investigation and monitor its systems in the future.

  • Google's Project Genie Lets You Generate Your Own Interactive Worlds
    by BeauHD on 29/01/2026 at 11:20 pm

    Google is letting outsiders experiment with DeepMind's Genie 3 "world model" via Project Genie, a tool for generating short, interactive AI worlds. The caveat: it requires a $250/month AI Ultra subscription, is U.S.-only, and has tight limits that make it more of a tech demo than a game engine. Engadget reports: At launch, Project Genie offers three different modes of interaction: World Sketching, exploration and remixing. The first sees Google's Nano Banana Pro model generating the source image Genie 3 will use to create the world you will later explore. At this stage, you can describe your character, define the camera perspective -- be it first-person, third-person or isometric -- and how you want to explore the world Genie 3 is about to generate. Before you can jump into the model's creation, Nano Banana Pro will "sketch" what you're about to see so you can make tweaks. It's also possible to write your own prompts for worlds others have used Genie to generate. One thing to keep in mind is that Genie 3 is not a game engine. While its outputs can look game-like, and it can simulate physical interactions, there aren't traditional game mechanics here. Generations are also limited to 60 seconds, as is the presentation, which is capped at 24 frames per second and 720p. Read more of this story at Slashdot.

  • Nvidia GeForce NOW Is Now Available Natively On Linux
    by BeauHD on 29/01/2026 at 10:40 pm

    NVIDIA has officially launched a native GeForce NOW client for Linux as a Flatpak, giving Linux gamers access to cloud-rendered RTX gaming. Phoronix reports: While confined to a Flatpak, for now NVIDIA is just "officially" supporting it on Ubuntu 24.04 LTS and later. Granted, thanks to Flatpak it should run on other non-Ubuntu distributions too but in terms of the official support and where they are qualifying their builds they are limiting it just to Ubuntu 24.04 LTS and later. [...] At launch the Flatpak build is also just for x86_64 Linux with no AArch64 Linux builds or similar at this time. Running GeForce NOW on Linux while games are rendered in NVIDIA's cloud with Blackwell GPUs, you still need to be using a modern GPU with H.264 or H.265 Vulkan Video support NVIDIA isn't yet supporting Vulkan Video AV1 with GeForce NOW on Linux but just H.264/H.265. If you are using NVIDIA graphics the NVIDIA R580 series or newer is recommended while using the X.Org session. If you are using Intel or AMD Radeon graphics, Mesa 24.2+ is recommended and using the Wayland session. When you are up and running with GeForce NOW on Linux, you have access to over 4,500 games. The free tier of GeForce NOW provides standard access to the gaming servers and limited session caps for an introductory-level experience. It's with the performance tier where you can enjoy RTX ray-tracing and 1440p @ 60 FPS performance and up to six hour sessions. With GeForce NOW's Ultimate tier is where you are running on GeForce RTX 5080 GPU servers with support for up to 5K @ 120 FPS gaming or 1080p @ 360 FPS with up to eight hour gaming sessions in length.
