  • Used Processor Leads To Game Ban
    by BeauHD on 02/10/2026 at 7:00 pm

    AmiMoJo shares a report from heise online: Anyone buying used hardware for a gaming PC needs to be careful: not just whether the components are still in order but also what the previous owner did with them. A case on Reddit shows this. Someone installed a used AMD processor, a Ryzen 7 5800X3D, in their PC. Because the previous owner was caught cheating, the new owner cannot start several online games. The problem was noticed in the first-person shooter "Valorant" from the development studio Riot. Right from the first start, the new owner was kicked out directly, according to their statement. Riot support confirmed that the previous owner had cheated. The processor is therefore on an internal blacklist -- and, with its installation in the PC, now apparently also some other components like the mainboard. Riot support does not remove such entries manually. In addition to "Valorant," all other PC games from Riot are affected: the strategy game "League of Legends," the auto-battler "Teamfight Tactics," the card game "Legends of Runeterra," the fighting game "2XKO," and likely future titles as well. Riot's "Vanguard" anti-cheat system traditionally runs deep in the Windows kernel and starts with the PC, but a June 2026 update allows it to launch with a game if security features such as TPM and Secure Boot are enabled. It's unclear how Riot uniquely identifies processors, though possibilities include hardware fingerprinting based on chip behavior or storing identification hashes in the Trusted Platform Module (TPM), which Vanguard accesses in the newer mode.

  • EU's Microsoft Teams Alternative Draws Bad Reviews From Officials
    by BeauHD on 02/10/2026 at 6:00 pm

    The European Commission has rolled out Element Pro as a self-hosted "sovereign back-up" to Microsoft Teams and the reviews aren't great. Politico reported that several officials questioned its usefulness and usability, with one calling it "absolute shit." Politico reports: "I don't understand the added value here," one official wrote on an internal staff message board, seen by POLITICO. Another described the tool as "absolute shit." A third official said that, judging matters on how well Element Pro works compared to Teams, the U.S. would "instantly win the war" if it ever decided to switch off its technology. All the officials were granted anonymity to speak freely. The Commission hosts the Element system on its own infrastructure rather than relying on Microsoft's cloud. That gives the institution greater control over its communications data and systems. "That is not the case with Teams, where all we have is a guarantee that Microslop will not peek inside," a fourth official wrote, presumably referring to Microsoft, in internal communications viewed by POLITICO. Element is a U.K. company whose software is used by governments and public-sector organizations in Europe. The application works much like Teams, allowing staff to hold "audio and video calls with Commission colleagues, send and receive files, and create dedicated 'rooms' for projects and conversations, much like chats and channels in M365 Teams," according to the Commission memo. "Obviously there are going to be some teething issues," said Element CEO Matthew Hodgson, adding there will always be "cognitive dissonance" when switching to a new app, if only because the "buttons" are in a different place. He noted that the United Nations and NATO also use Element Pro. "Change is always painful, particularly if it's a switch from a much-used program like Teams." Read more of this story at Slashdot.

  • Judge Dismisses Chegg and Penske Antitrust Lawsuits Targeting Google AI Search
    by BeauHD on 02/10/2026 at 5:00 pm

    A federal judge has dismissed antitrust lawsuits from Chegg and Penske Media accusing Google of harming publishers by using their content in AI Overviews and other AI search features without compensating them or providing a meaningful opt-out. Ars Technica reports: The lawsuits were filed in 2025, and Google requested a dismissal earlier this year. Chegg, an education and learning platform, claimed in its lawsuit that Google illegally scraped its educational content. This allowed Gemini models to essentially recreate that content and reduce the site's traffic. Penske, which owns publications like Rolling Stone and Variety, filed a similar case that alleged lost traffic. Specifically, the publisher claimed it was unfair that sites indexed for organic search would also have their content harvested for AI answers, with no way to opt out. These arguments did not sway the judge, who noted that Google's implicit agreement with websites is not legally relevant. "Plaintiffs have pleaded only that they have an 'expectation' that Google will send them search "traffic if they make their content available for free," wrote Mehta. "But an expectation is not an agreement. It is simply how a general search engine works." Since Google never had a formal arrangement with either Chegg or Penske, antitrust law doesn't apply. And Mehta is aware of the legal issues surrounding search. He also heard the DOJ's long-running search antitrust case against Google, eventually finding that Google violated the law. However, the government didn't get the harsh penalties it wanted in that case. Read more of this story at Slashdot.

  • Social Media Harms Democracy By Spreading Rumors, Survey Shows
    by BeauHD on 02/10/2026 at 4:00 pm

    An anonymous reader quotes a report from Reuters: A growing number of people think social media manipulates and divides people and harms democracy, Pew Research Center said on Thursday, echoing rising concern and tighter scrutiny across the world. Companies running popular social platforms, including Meta, Snap, and TikTok, have faced thousands of lawsuits and paid large sums to settle claims that they harmed users. Governments, meanwhile, have sought foolproof ways to protect their citizens' privacy. Australia has proposed rules to let users opt out of algorithmically recommended feeds, after becoming the first country to ban social media for children under 16. Pew's latest survey showed that 82% of Australian adults support the government's move to restrict social media access for children. A majority of respondents said social media informs people and gives them a voice in politics, but there was a broad rise in those who now see social media as a "bad thing" compared to 2022, according to the report. People in wealthier countries, including the US, Canada and UK, are more inclined to believe that social media is harming democracy, versus their counterparts in economies with lower gross domestic product per capita -- such as Ghana, Kenya and Nigeria. The US is among the most skeptical, with 64% of adult respondents saying social media harms democracy. The share of people who consider social media bad for democracy increased in 16 of 26 countries where older data was available. Pew Research said it surveyed more than 45,000 people in 37 countries, while polling an additional 5,511 US adults on American social media use. Read more of this story at Slashdot.

  • Error-Prone AI Nearly Sparked World War Three Last Month
    by BeauHD on 02/10/2026 at 3:00 pm

    In an op-ed for The Guardian, authors Timnit Gebru and Emily M. Bender argue that policymakers are focusing too heavily on hypothetical "superintelligence" while overlooking the more immediate danger of deploying unreliable AI in high-stakes settings. They point to an as-yet independently unverified CNN report claiming U.S. officials nearly intercepted a Chinese vessel after an AI-assisted intelligence report incorrectly said it was carrying nuclear-weapons components. From the article: While so many of us were focused on fictional superintelligent machines that we were told could hypothetically cause human extinction, however, there was a more serious story being reported. A series of events almost got us to armageddon, not caused by "rogue, superintelligent AI," but by government reliance on error-prone systems that are marketed by their manufacturers as being close to superintelligent. A CNN report published on September 18, which hasn't been verified by other major outlets, describes how the US "almost started a war" with China, based on an intelligence report that claimed a Chinese ship was transporting components of nuclear weapons. Military personnel made plans to intercept the Chinese vessel, complete with aircraft and soldiers ready to board the ship. A military skirmish of this kind between China and the US could quickly escalate and spiral into world war three. It was only moments before executing on the plan that American officials further investigated the intelligence report and found that it had been generated with the use of a chatbot and contained erroneous information about the vessel's contents. Unlike the terminator, "rogue AI," scenario, this incident didn't galvanize lawmakers into announcing calls for regulation so as to avoid potential human extinction. Media outlet after media outlet didn't warn the public that we almost triggered a war against a nuclear superpower because of our military's reliance on error-prone chatbots.

  • 20% of Swiss Glaciers Lost In Five Years
    by BeauHD on 02/10/2026 at 11:00 am

    Swiss glaciers lost 5.5% of their ice volume in the first eight months of 2026, bringing total losses since 2021 to 19.4%. Researchers say some glaciers are now collapsing from within as meltwater carves out large cavities. The Guardian reports: Matthias Huss, a glaciologist at ETH Zurich and lead author of the report, said many people do not realize how fast glaciers are retreating, or that just one generation ago some now-barren sites used to sit beneath hundreds of meters of ice. The scientists have not yet compiled a formal tally of lost glaciers this year but said they had witnessed the death of a number of small ones. "I visited one last week and it's so impressive to stand in this moonlike landscape where there was a big layer of ice -- an extensive glacier -- just a few years ago," said Huss. "And now it's a rock desert where there's some scattered blocks of old ice still lying around and melting on the hot rocks." The report, a collaboration between the Swiss Glacier Monitoring Network and the Swiss Commission for Cryosphere Observation, found the mean thickness of individual glaciers fell by between 2.5 metres and 4 metres in 2026. Huss said scientists were increasingly seeing glaciers collapse from the inside -- the result of internal streams beneath the ice that excavate caverns -- rather than simply retreating from surface heat. [...] Analysis published by MeteoSwiss on Tuesday found the summer half-year from April to September was the hottest and driest it had been since records began in 1864. In that time, humanity has filled the atmosphere with 1.8tn tons of carbon dioxide and heated the planet by about 1.4C. Read more of this story at Slashdot.
