  • AT&T Sues California In Bid To Stop Offering Traditional Phone Service
    by BeauHD on 22/05/2026 at 3:30 am

    An anonymous reader quotes a report from Reuters: AT&T on Wednesday filed suit (PDF) against California officials seeking a court order declaring it does not have to continue offering traditional copper wire phone service to new customers as it vowed to spend $19 billion on modern telecom services. California requires the U.S. wireless carrier to spend $1 billion annually to maintain a century-old telephone network that few use, AT&T said, saying the network now serves just 3% of households in AT&T's California territory. AT&T's suit named the California Public Utilities Commission and the state attorney general. AT&T said it is committing to investing $19 billion in California as it works to connect more than 4 million additional households and businesses across California by 2030 and added IP-based networks are far more reliable and efficient. AT&T also Wednesday asked the Federal Communications Commission for permission to discontinue traditional phone service in parts of California where it has faster, more reliable service available. It also filed a petition with the FCC to declare that California's rules that effectively require AT&T to power, repair and sell traditional phone service, even after the FCC has authorized the service to be phased out, are preempted by federal standards. AT&T added that transitioning from copper will save an estimated 300 million kilowatt-hours annually by 2030 or the equivalent of eliminating emissions from 17 million gallons of gasoline. The company added that California has already suffered about 2,000 outages from copper thefts this year and it struggles to find replacement parts. The federal government and virtually all states where AT&T historically offered copper-wire service "have now eliminated outdated regulatory obstacles" allowing AT&T to begin powering down its old network and increasing its investments in modern communication technologies, the company said in its lawsuit filed in U.S. District Court in southern California.

  • Thousands of Zillow Listings In Chicago Have Vanished
    by BeauHD on 21/05/2026 at 11:00 pm

    Thousands of Chicago-area Zillow and Trulia listings disappeared after Midwest Real Estate Data cut off Zillow's access to its feed, "in the latest escalation of a legal battle with Lisle-based Midwest Real Estate Data (MRED)," reports the Chicago Sun-Times. "The fight is over MRED's private listing network, where homes for sale are shared among real estate professionals. And MRED followed through on a threat to cut Zillow's access to its listing data feed." From the report: There were nearly 5,000 Chicago homes listed on Zillow Tuesday, but as of Wednesday afternoon, that number plummeted to about 1,700. Meanwhile, other listing sites like Redfin and Realtor.com show about 5,000 to 8,000 listings in Chicago. MRED manages listings -- submitted by brokers -- throughout Illinois, as well as parts of Wisconsin and Indiana. The regional multiple listing service has more than 43,000 members and processed more than 264,000 listings worth $43 billion in 2025. The loss of listings on Zillow's websites have made a behind-the-scenes real estate industry fight public. And it now hinders some consumers in their search to buy a home, while also limiting the marketing opportunity for sellers. The legal fight is basically over who gets to control how home listings are marketed and displayed online. Zillow recently adopted a rule saying that if a home is marketed privately, such as behind a paywall, login, or private listing network, it should not also appear on Zillow. The policy, the real estate marketplace says, is meant to discourage "pocket listings," preserve transparency, and make sure buyers can see the full market. MRED sees it differently. It expanded its private listing network and partnered with Compass, which wants to give sellers more control over whether their homes are broadly publicized or marketed privately first. MRED argues that Zillow is violating MLS rules and licensing agreements by refusing to display certain listings, including private Compass listings. Consumers are now caught in the middle...

  • Vivaldi 8.0 Arrives With 'Most Significant Design Overhaul' In Browser's History
    by BeauHD on 21/05/2026 at 10:00 pm

    Vivaldi 8.0 is being pitched as the browser's "most significant design overhaul" yet, featuring a new unified, edge-to-edge interface, six preset layouts, and deeper customization across tabs, toolbars, panels, and themes. The company is also taking a swipe at rivals chasing questionable AI features. Neowin reports: After updating to version 8.0, Vivaldi will present you with the ability to select one of the six pre-built styles. You can select a minimal edge-to-edge theme, one with the UI fully hidden for focused work, or a power user variant with everything on the screen. The update comes with a built-in collection theme, and users are free to select one of over 7,000 community themes available on the official website. Vivaldi says that while other browsers were busy adding questionable AI features, it focused on "a foundation that no other browser can match" with flexible tab management, built-in productivity tools, and advanced customization. At the same time, Vivaldi does not force the new design onto its users, so those who prefer the previous user interface can go back to it at any moment in settings. "With 8.0, we have done something we have been working toward for a long time: we have given the browser itself a visual system worthy of everything it can do," says Vivaldi's CEO and co-founder, Jon Stephenson von Tetzchner. "With this update Vivaldi feels like one considered, coherent tool." You can download Vivaldi 8.0 and view the changelog at their respective links. Read more of this story at Slashdot.

  • Trump Calls Off AI Executive Order Over Concern It Could Weaken US Tech Edge
    by BeauHD on 21/05/2026 at 9:00 pm

    Trump called off a planned AI executive order just hours before a signing ceremony because he said he was worried the framework could slow America's lead over China. "We're leading China, we're leading everybody, and I don't want to do anything that's going to get in the way of that lead," Trump told reporters. The Associated Press reports: The order would have established a framework for the government to vet the national security risks of the most advanced AI systems before their public release, according to a person familiar with the White House's deliberations with the tech industry but not authorized to speak about it publicly. The directive was being characterized as a voluntary collaboration with participating U.S.-based tech companies, including Anthropic, OpenAI and Google, the person said. There are competing factions within the administration, said Serena Booth, a computer science professor at Brown University and former AI policy fellow in a Democratic-led Senate committee. "We do see this kind of public fighting," she said. "'We will release an executive order. No, we won't. We're going to sign it this afternoon. Oh, the signing is canceled.' I think this whiplash is because we're seeing these fractures.'" Some of those divides are balancing what Booth said is a "reasonable idea" to test the most capable AI models before their public release, with a concern that government scrutiny, if it takes too long, could burden AI developers. "It does come at a potential very large cost to innovation and speed of development," she said. "There is, I think, a real risk here and I do see both sides." [...] "They don't want to do it because it's politically risky in a million different ways," said Dean Ball, now at the Foundation for American Innovation. Ball said he would welcome an executive order that would get those companies working more closely with the government on cybersecurity but "ultimately, I'm fine with them taking time to get this right."

  • Flipper One Could Be the Ultimate Linux Cyberdeck
    by BeauHD on 21/05/2026 at 8:00 pm

    BrianFagioli writes: Flipper Devices has finally revealed Flipper One, a Linux-powered cyberdeck that sounds less like a gadget and more like an attempt to rebuild portable ARM computing from the ground up. Unlike Flipper Zero, which focuses on offline protocols like RFID and Sub-1 GHz radio, Flipper One is all about networking, modular hardware, SDR experimentation, local AI, and upstream Linux kernel support. The company says it wants to build "the most open and best-documented ARM computer in the world," complete with zero vendor BSP dependency and as few binary blobs as possible. That alone is enough to get Linux folks paying attention. The hardware itself is loaded with nerd bait: dual Gigabit Ethernet, Wi-Fi 6E, M.2 expansion for SSDs and 5G modems, GPIO add-ons, HDMI 2.1, and a dual-processor architecture pairing a Rockchip RK3576 with a Raspberry Pi RP2350 microcontroller. Flipper Devices is even developing its own small-screen Linux UI framework because squeezing KDE onto tiny touchscreens is miserable. The company openly admits the project is financially and technically terrifying, which honestly makes this announcement feel more believable than most startup hardware pitches. Whether Flipper One succeeds or not, it is one of the most ambitious Linux hardware projects in years. Read more of this story at Slashdot.

  • US To Award $2 Billion To Quantum Companies, Take Equity Stakes
    by BeauHD on 21/05/2026 at 7:00 pm

    An anonymous reader quotes a report from the Quantum Insider: The Trump administration is preparing a new round of industrial policy aimed at quantum computing, with roughly $2 billion in grants expected to go to nine companies developing quantum hardware and related technologies. According to Reuters, citing a Wall Street Journal report, the U.S. Department of Commerce plans to distribute the funding through deals that also give the federal government equity stakes in the companies receiving the awards. The approach would expand Washington's increasingly direct involvement in sectors viewed as strategically important to national security, advanced manufacturing and competition with China. Reuters reported that IBM is expected to receive the largest share of the package at about $1 billion. Semiconductor manufacturer GlobalFoundries is slated to receive approximately $375 million, according to the report. Other recipients are expected to include D-Wave Quantum, Rigetti Computing, Quantinuum and Infleqtion, with each company potentially receiving around $100 million, Reuters reported. Australian quantum startup Diraq could receive about $38 million, according to the Wall Street Journal report cited by Reuters. Fast Company notes in its reporting that IBM will invest the funds it receives into a new IBM company called Anderon. It will also match the grant with another $1 billion in cash. "Anderon will operate as a state-of-the-art 300-millimeter quantum wafer foundry," IBM stated in an announcement. "It will help the nation solidify its leadership at the center of a thriving new quantum industry that is estimated to generate up to $850 billion in economic value by 2040 and spur American economic growth while also bolstering national security." Quantum computing stocks soared after the news. As of publication, IBM is up about 9.7%, D-Wave is up about 28.1%, and Rigetti is up about 26.7%. Meanwhile, Global Foundries rose about 13.8% and Infleqtion jumped about 30.9%. Read more of this story at Slashdot.
