  • Samsung Galaxy Z Trifold Will Cost $2,900 in the US
    by msmash on 27/01/2026 at 2:45 pm

    Samsung said today that its Galaxy Z TriFold, the first tri-fold smartphone to ship in the U.S., will be available starting January 30 at a price point of $2,899 -- substantially more expensive than any other phone on the U.S. market, including Samsung's own $2,000 Galaxy Z Fold 7 and a fully loaded 2TB iPhone 17 Pro Max. The company will only sell the device through its website and Samsung Experience Stores; mobile carrier partners including Verizon, T-Mobile, and AT&T won't be offering it directly. The TriFold unfolds into a 10-inch tablet, measures 3.9mm at its thinnest point, and is rated for 200,000 folds over its lifetime. Samsung launched the TriFold in South Korea on December 12 at 3.59 million won, about $2,450 at the time. Early reviews have praised the expansive inner screen for video but noted the 309-gram weight, thick folded dimensions, and half-baked software as significant drawbacks.

  • How Anthropic Built Claude: Buy Books, Slice Spines, Scan Pages, Recycle the Remains
    by msmash on 27/01/2026 at 2:06 pm

    Court documents unsealed last week in a copyright lawsuit against Anthropic reveal that the AI company ran an operation called "Project Panama" to buy millions of physical books, slice off their spines, scan the pages to train its Claude chatbot, and then send the remains to recycling companies. The company spent tens of millions of dollars on the effort and hired Tom Turvey, a Google executive who had worked on the legally contested Google Books project two decades earlier. Anthropic bought books in batches of tens of thousands from retailers including Better World Books and World of Books. A vendor document noted the company was seeking to scan between 500,000 and two million books. Before Project Panama, Anthropic co-founder Ben Mann downloaded books from LibGen, a shadow library of pirated material, over 11 days in June 2021. He later shared a link to the Pirate Library Mirror site with colleagues, writing "this is awesome!!!" Meta employees similarly downloaded books from torrent platforms after approval from Mark Zuckerberg, court filings allege, though one engineer wrote that "torrenting from a corporate laptop doesn't feel right." Anthropic settled for $1.5 billion in August without admitting wrongdoing. Read more of this story at Slashdot.

  • Microsoft Is Refreshing the Xbox Cloud Gaming Web Experience
    by BeauHD on 27/01/2026 at 1:00 pm

    An anonymous reader quotes a report from Thurrott: Microsoft is testing a refresh of the Xbox Cloud Gaming web experience in public preview. "This preview is a first look at our new web interface on your browser and lets you try the updated design and product flow before it is rolled out broadly," Microsoft's Patrick Siu explains. "Players who opt in to this preview will see some changes to their experience including updated navigation features and a refreshed look and feel. As this is a preview, some functions may not yet be available or may behave differently than the current web experience. We will continue iterating during the preview period and changes may be made over time." [...] There's no real info about what's in the new experience, oddly. Microsoft notes only that it "lays the foundation for accelerating [their] ability to build new experiences for players," and that it "helps [them] validate the new web platform and refine the experience for everyone." The public preview can be found at xbox.com/play. Read more of this story at Slashdot.

  • ReactOS Celebrates 30 Years

    jeditobe writes: ReactOS, the open-source operating system aimed at binary compatibility with Windows, recently marked its 30th anniversary. Launched in 1996, ReactOS has focused on providing a free alternative to Windows, with compatibility for Windows applications and drivers. Though still in development, it has made significant progress in recent years, including improvements to USB support, better hardware compatibility, and enhanced performance with the release of version 0.4.15. The upcoming 0.4.16 release is set to introduce UEFI support, KMDF and WDDM graphics driver support, marking a major step forward in ReactOS's development. Read more of this story at Slashdot.

  • Lawsuit Alleges That WhatsApp Has No End-to-End Encryption
    by BeauHD on 27/01/2026 at 7:00 am

    Longtime Slashdot reader schwit1 shares a report from PCMag: A lawsuit claims that WhatsApp's end-to-end encryption is a sham, and is demanding damages, but the app's parent company, Meta, calls the claims "false and absurd." The lawsuit was filed in a San Francisco US district court on Friday and comes from a group of users based in countries such as Australia, Mexico, and South Africa, according to Bloomberg. As evidence, the lawsuit cites unnamed "courageous whistleblowers" who allege that WhatsApp and Meta employees can request to view a user's messages through a simple process, thus bypassing the app's end-to-end encryption. "A worker need only send a 'task' (i.e., request via Meta's internal system) to a Meta engineer with an explanation that they need access to WhatsApp messages for their job," the lawsuit claims. "The Meta engineering team will then grant access -- often without any scrutiny at all -- and the worker's workstation will then have a new window or widget available that can pull up any WhatsApp user's messages based on the user's User ID number, which is unique to a user but identical across all Meta products." "Once the Meta worker has this access, they can read users' messages by opening the widget; no separate decryption step is required," the 51-page complaint adds. "The WhatsApp messages appear in widgets commingled with widgets containing messages from unencrypted sources. Messages appear almost as soon as they are communicated -- essentially, in real-time. Moreover, access is unlimited in temporal scope, with Meta workers able to access messages from the time users first activated their accounts, including those messages users believe they have deleted." The lawsuit does not provide any technical details to back up the rather sensational claims. Read more of this story at Slashdot.

  • China Hacked Downing Street Phones For Years
    by BeauHD on 27/01/2026 at 3:30 am

    An anonymous reader quotes a report from The Telegraph: China hacked the mobile phones of senior officials in Downing Street for several years, The Telegraph can disclose. The spying operation is understood to have compromised senior members of the government, exposing their private communications to Beijing. State-sponsored hackers are known to have targeted the phones of some of the closest aides to Boris Johnson, Liz Truss and Rishi Sunak between 2021 and 2024. It is unclear whether the hack included the mobile phones of the prime ministers themselves, but one source with knowledge of the breach said it went "right into the heart of Downing Street." Intelligence sources in the US indicated that the Chinese espionage operation, known as Salt Typhoon, was ongoing, raising the possibility that Sir Keir Starmer and his senior staff may also have been exposed. MI5 issued an "espionage alert" to Parliament in November about the threat of spying from the Chinese state. [...] The attack raises the possibility that Chinese spies could have read text messages or listened to calls involving senior members of the Government. Even if they were unable to eavesdrop on calls, hackers may have gained access to metadata, revealing who officials were in contact with and how frequently, as well as geolocation data showing their approximate whereabouts.
