  • T-Mobile Appears To Be Quitting VMware Amid Support Rights Lawsuit With Broadcom
    by BeauHD on 01/07/2026 at 11:00 pm

    T-Mobile appears to be migrating its 303,000-core VMware environment to another platform while fighting Broadcom in court for the extended support it says its perpetual-license agreement guarantees. "The matter is somewhat urgent," The Register reports, because a court-ordered support arrangement expires August 3, "so T-Mobile may soon be unable to get support for its very substantial VMware estate." The Register reports: The dispute relates to a deal T-Mobile struck with VMware in August 2023, which saw the telco acquire perpetual licenses and two years of support for some software, plus the option for a further year of support. When Broadcom acquired VMware in 2023, it stopped selling perpetual licenses and standalone support deals for customers with those licenses. Broadcom also reduced the virtualization giant's product range from over 150 products to two subscription-only bundles. Broadcom now mostly sells its Cloud Foundation (VCF) private cloud suite. Customers including AT&T and Tesco tried to exercise their right to extended support, but Broadcom declined to do so. AT&T settled on confidential terms. Tesco is pursuing the matter in the courts. When customers exercise their option for extended support, Broadcom argues it can't deliver because the products covered by the contract don't exist anymore, its contracts allow it to deny support for dead products, and subscriptions are now the industry standard. T-Mobile started using VMware's products in 2008. In one hearing, the carrier's counsel described T-Mobile's VMware implementation as "the base of the entire internal network" and "the place where 1,000 applications reside." Another filing, from Broadcom, says the telco runs VMware software on over 303,000 CPU cores. Court documents allege that in 2024 Broadcom notified T-Mobile it would not renew support after the initial two-year deal expired in 2025. The two parties kept talking about possible new arrangements. T-Mobile also sought an injunction that would compel Broadcom to provide extended support. Broadcom opposed the injunction, arguing that T-Mobile deliberately waited too long to seek it. At one point T-Mobile suggested a $20 million deal for another two years of support. An affirmation filed last week by T-Mobile vice president of technology Kevin Luu says the carrier sought that arrangement "to be able to complete T-Mobile's transition away from VMware at a more deliberate pace." The court eventually granted the injunction forcing Broadcom to offer support beyond August 2025, but required T-Mobile to pay $5.28 million and post a $500,000 undertaking. Broadcom continued to provide support but also sought damages on grounds that the injunction meant it missed out on a new deal with T-Mobile. The telco has rubbished that argument in part because the two parties were still talking about a new deal. Broadcom later proposed to charge $24 million for extended support covering six products, a sum it said would cover over 20 staff needed to support T-Mobile. The carrier fired back by pointing out that it has made just two support calls in 2026, which hardly justifies such a massive staff and expense. Read more of this story at Slashdot.

  • Meta Is Reportedly Building Its Own Cloud Business
    by BeauHD on 01/07/2026 at 10:00 pm

    Meta is reportedly developing its own cloud business that could sell access to its AI models and lease data-center computing capacity to other companies. The move would put Meta in direct competition with Amazon, Google, and SpaceX. Engadget reports: The cloud business could offer multiple services, according to [Bloomberg], like selling access to AI models run on Meta's infrastructure, or leasing the computing power of its data centers to other companies looking to train AI. Offering something akin to Amazon Web Services could help make back some of what Meta has already spent on its new bet. As part of its AI plans, the company has committed to investing $600 billion in the US by 2028. Meta has also already made more than a few expensive hires to build its AI superintelligence team. Meta Compute, the data center and AI-focused initiative Meta created in January, is currently developing the new cloud business, according to Bloomberg. Read more of this story at Slashdot.

  • Cloudflare Pushes AI Companies To Pay For Publishers' Content
    by BeauHD on 01/07/2026 at 9:00 pm

    BrianFagioli writes: Cloudflare announced new controls that give publishers more say over how AI companies access and use their content. Beginning September 15, new Cloudflare sites will allow traditional search indexing while blocking AI training and AI agent access on ad supported pages by default. The company is also expanding its monetization efforts with a Pay-Per-Use model that aims to compensate publishers when their content contributes to AI generated answers rather than simply being crawled. Cloudflare argues that publishers should not have to choose between being discoverable online and giving away their work for free to AI systems. Read more of this story at Slashdot.

  • Scientists Made a Cell From Scratch For First Time
    by BeauHD on 01/07/2026 at 8:00 pm

    AleRunner writes: The first fully synthetic cell ("SpudCell") has been created in the Department of Genetics at the University of Minnesota. Strictly speaking, it's described as a "cell-like system constructed entirely from known chemical components that can perform a complete cell cycle." It is able to replicate, but only for approximately five generations. The key advance is that the cell is "built entirely bottom-up from individually purified, non-living components," although it still contains material from E. coli bacteria. "PURE is a defined mixture of 36 purified enzymes from E. coli bacteria," including ribosomes, that provides the infrastructure for genetic replication. CNN has an article on the advance, including interview material with Professor Kate Adamala, who led the research. "I know the full ingredient list of the cell. I know exactly what chemicals, what molecules, at what concentrations," she said. "It is fully defined, which means we can engineer it." "Humans did not create life," notes an anonymous Slashdot reader. "Researchers call it a constructed cell, not 'life created in the lab' but a 'genuine milestone on the road toward that question.' It lacks full autonomy (needs feeding, no independent evolution)." Special thanks to Slashdot readers kemosabi and AleRunner for submitting the story and additional sources, including reports from The New York Times and The Guardian, as well as information from the University of Minnesota Twin Cities.

  • Reddit Will Require You To Log In To Use Old Reddit
    by BeauHD on 01/07/2026 at 7:00 pm

    An anonymous reader quotes a report from Ars Technica: Reddit will start requiring people to be logged into Reddit to use old.reddit.com. The new requirement will take effect "over the next month," a Reddit employee going by the username boat-botany announced on the social media platform today. The person claimed that the change is part of an ongoing effort to "tighten how automated systems access Reddit." The Reddit employee wrote: "Old Reddit's logged-out experience is a significant source of abusive scraping and automated traffic on the platform. It's also an important interface for many long-time mods and Redditors. To strike the right balance between preserving your access to Old Reddit while preventing abusive scraping and automated traffic, over the next month we will start requiring everyone to log in." In a follow-up comment, boat-botany defined abusive behavior as that which violates Reddit's rule prohibiting activity that interferes with the platform's "normal use" or that "create[s] programs or applications" that break Reddit's (controversial) API rules. "By logging in, we get a lot more signal that allows us to detect whether an account is breaking the rules, and then we can block that traffic or enforce those accounts," boat-botany said. Asked why boat-botany scrapes New Reddit less frequently than Old Reddit, the Reddit employee pointed to another commenter's explanation. "[T]he shape of malicious traffic is always changing," the user, Nestramutat, wrote. "It's going to be a constant cat and mouse game[.] As you ban one method, a new one gets developed. It's easy to see abusive traffic in hindsight, but it's harder to pre-emptively block it. Given that they're claiming Old Reddit doesn't have the modern security stack, this is likely proving to be an even greater challenge." Nestramutat said that the login requirement will add a barrier against threat actors. "You're also now attaching an account ID to every malicious request, plus account creation is only available on New Reddit (with the enhanced security stack)." As for how long Old Reddit will exist, boat-botany left the door open for its retirement. "We can't promise it will be around forever, but [Reddit CEO Steve Huffman] himself has said we'll keep supporting it while folks are still using it," boat-botany wrote. "That said, it doesn't have the same modern security tech stack reddit.com has, so we need to tighten security on old reddit to keep it viable." Read more of this story at Slashdot.

  • Sony PlayStation Will Stop Releasing Games On Discs In 2028
    by BeauHD on 01/07/2026 at 6:00 pm

    Longtime Slashdot reader AmiMoJo shares a report from the BBC: New PlayStation games will no longer be released on discs from January 2028, the gaming giant has announced. Sony said in a blog post new games would still be able to be bought in shops, but they would come with a digital code. It comes just days after Rockstar announced the hotly-anticipated Grand Theft Auto VI would similarly launch without a physical disc. It marks a significant moment for the gaming industry, which has in recent years begun to rely more and more on digital distribution. Sony said the move came "as consumer preferences and the broader entertainment industry continue to shift away from physical discs to digital." "This is a natural direction for Sony Interactive Entertainment to adapt to consumer trends as the general preference for digital media significantly outpaces physical discs," it added. [...] PlayStation said the move would have no impact on games which are already released, or would be released before January 2028. Read more of this story at Slashdot.
