  • Trump's TikTok Deal Benefited Firms That 'Personally Enriched' Him, Lawsuit Says
    by BeauHD on 05/03/2026 at 9:00 pm

    An anti-corruption group has filed a lawsuit (PDF) against Donald Trump and Attorney General Pam Bondi over the deal that transferred TikTok's U.S. operations to a group of investors tied to the administration. The suit claims the arrangement violates a 2024 law requiring ByteDance to divest and alleges the deal financially benefited Trump allies while leaving the platform's algorithm under Chinese ownership. NBC News reports: The suit, filed by the Public Integrity Project, a law firm that seeks to raise the "reputational cost of corruption in America," argues the deal violates a law intended to prevent the spread of Chinese government propaganda and has enriched Trump's allies. That law, signed by then-President Joe Biden in 2024, said that TikTok couldn't be distributed in the United States unless the Chinese company ByteDance found an American-based corporate home by the day before Donald Trump returned to office. The law was upheld by the Supreme Court. "The law was clear, but it was never enforced," says the lawsuit, filed Thursday in the U.S. Court of Appeals for the District of Columbia Circuit. "Shortly after the deadline to divest passed, President Trump issued an executive order purportedly granting an extension for TikTok to find a domestic owner and directed his Attorney General not to enforce the law." The plaintiffs in the suit are two software engineers from California: One is a shareholder in Alphabet Inc., YouTube's parent company; the other is a shareholder in Meta Platforms, Inc., which is Instagram's parent company. Both say they suffered financially due to the non-enforcement of the law. "The original motivation for this law was to prevent the Chinese government from pushing propaganda onto American audiences," said Brendan Ballou, CEO of the Public Integrity Project and a former Justice Department prosecutor. "The deal that the president approved is the absolute worst of all possible worlds, because right now ByteDance continues to own the algorithm, which means that it can censor the content that it doesn't like, but at the same time Oracle controls the data and it can censor the information that it doesn't like. Really it's a situation that's going to be terrible for users, and terrible for free speech on the platform." Read more of this story at Slashdot.

  • AMD Will Bring Its 'Ryzen AI' Processors To Standard Desktop PCs For First Time
    by BeauHD on 05/03/2026 at 8:00 pm

    An anonymous reader quotes a report from Ars Technica: AMD has been selling "Ryzen AI"-branded laptop processors for around a year and a half at this point. In addition to including modern CPU and GPU architectures, these are attempting to capitalize on the generative AI craze by offering chips with neural processing units (NPUs) suitable for running language and image-generation models locally, rather than on some company's server. But so far, AMD's desktop chips have lacked both these higher-performance NPUs and the Ryzen AI label. That changes today, at least a little: AMD is announcing its first three Ryzen AI chips for desktops using its AM5 CPU socket. These Ryzen AI 400-series CPUs are direct replacements for the Ryzen 8000G processors, rather than the Ryzen 9000-series, and they combine Zen 5-based CPU cores, RDNA 3.5 GPU cores, and an NPU capable of 50 trillion operations per second (TOPS). This makes them AMD's first desktop chips to qualify for Microsoft's Copilot+ PC label, which enables a handful of unique Windows 11 features like Recall and Click to Do. The six chips AMD is announcing today -- the 65 W Ryzen AI 7 Pro 450G, Ryzen AI 5 Pro 440G, and Ryzen AI 5 Pro 435G, along with low-power 35 W "GE" variants -- all bear AMD's "Ryzen Pro" branding as well, which means they support a handful of device management capabilities that are important for business PCs managed by IT departments. At this point, it doesn't seem as though AMD will be offering boxed versions to regular consumers; the Ryzen AI desktop chips will appear mainly in business PCs that don't need a dedicated graphics card but still benefit from more robust graphics than AMD offers in regular Ryzen desktop CPUs. Like past G-series Ryzen chips, these are essentially laptop silicon repackaged for desktop systems. They share most of their specs in common with Ryzen AI 300 laptop processors, despite their Ryzen AI 400-series branding. The two chip generations are extremely similar overall, but the Ryzen AI 400-series laptop CPUs include slightly faster 55 TOPS NPUs. Read more of this story at Slashdot.

  • OpenAI Releases New ChatGPT Model For Working In Excel and Google Sheets
    by BeauHD on 05/03/2026 at 7:00 pm

    OpenAI today released GPT-5.4, an upgraded ChatGPT model designed to be faster, cheaper, and more accurate for workplace tasks. The update also introduces tools that let ChatGPT work directly inside Excel and Google Sheets. Axios reports: GPT-5.4 is designed to be less error-prone, more efficient and better at workplace tasks like drafting documents, OpenAI said. The new model can create files in fewer tries with less back-and-forth than prior models, the company said. GPT-5.4 outperformed office workers 83% of the time on GDPval, an OpenAI benchmark measuring performance on real-world tasks across 44 occupations. The model can also solve problems using fewer tokens, OpenAI says -- which can translate to faster responses and lower costs. The company is also debuting OpenAI for Financial Services, a set of new tools that includes the version of ChatGPT that runs inside spreadsheets and new apps and skills within ChatGPT. Partners include FactSet, MSCI, Third Bridge and Moody's. Read more of this story at Slashdot.

  • Tim Sweeney Signed Away His Right To Criticize Google Until 2032
    by BeauHD on 05/03/2026 at 6:00 pm

    As part of Epic's settlement with Google over the Play Store, Epic CEO Tim Sweeney agreed to stop criticizing Google's app store practices until 2032 and even publicly support the revised policies. The deal also prohibits Epic from pushing for further changes to Google's platform rules. The Verge reports: On March 3rd, he not only signed away Epic's rights to sue and disparage the company, he signed away his right to advocate for any further changes to Google's app store polices. He can't criticize Google's app store practices. In fact, he has to praise them. The contract states that "Epic believes that the Google and Android platform, with the changes in this term sheet, are procompetitive and a model for app store / platform operations, and will make good faith efforts to advocate for the same." He may even have to appear in other courts around the world to defend this deal with Google, and Google gets to make sure his public statements are supportive of the deal from here on out. And while Epic can still be part of the "Coalition for App Fairness," the organization that Epic quietly and solely funded to be its attack dog against Google and Apple, he can only point that organization at Apple now. "Google is opening up Android all the way with robust support for competing stores, competing payments, and a better deal for all developers. So, we've settled all of our disputes worldwide. THANKS GOOGLE!," Sweeney wrote in a post on X on Wednesday. Read more of this story at Slashdot.

  • Anthropic CEO Dario Amodei Calls OpenAI's Messaging Around Military Deal 'Straight Up Lies'
    by BeauHD on 05/03/2026 at 5:00 pm

    An anonymous reader quotes a report from TechCrunch: Anthropic co-founder and CEO Dario Amodei is not happy -- perhaps predictably so -- with OpenAI chief Sam Altman. In a memo to staff, reported by The Information, Amodei referred to OpenAI's dealings with the Department of Defense as "safety theater." "The main reason [OpenAI] accepted [the DoD's deal] and we did not is that they cared about placating employees, and we actually cared about preventing abuses," Amodei wrote. Last week, Anthropic and the U.S. Department of Defense (DoD) failed to come to an agreement over the military's request for unrestricted access to the AI company's technology. Anthropic, which already had a $200 million contract with the military, insisted the DoD affirm that it would not use the company's AI to enable domestic mass surveillance or autonomous weaponry. Instead, the DoD -- known under the Trump administration as the Department of War -- struck a deal with OpenAI. Altman stated that his company's new defense contract would include protections against the same red lines that Anthropic had asserted. In a letter to staff, Amodei refers to OpenAI's messaging as "straight up lies," stating that Altman is falsely "presenting himself as a peacemaker and dealmaker." Amodei might not be speaking solely from a position of bitterness, here. Anthropic specifically took issue with the DoD's insistence on the company's AI being available for "any lawful use." [...] "I think this attempted spin/gaslighting is not working very well on the general public or the media, where people mostly see OpenAI's deal with the DoW as sketchy or suspicious, and see us as the heroes (we're #2 in the App Store now!)," Amodei wrote to his staff. "It is working on some Twitter morons, which doesn't matter, but my main worry is how to make sure it doesn't work on OpenAI employees." Read more of this story at Slashdot.

  • Amazon's Bahrain Data Center Targeted By Iran For US Military Support
    by BeauHD on 05/03/2026 at 4:00 pm

    Iranian state media said on Wednesday that it targeted Amazon's data center in Bahrain due to the company's support of the U.S. military. The drone strike that occurred on Sunday disrupted core cloud services and caused "prolonged" outages. Two data centers in the UAE were also damaged by drone strikes. CNBC reports: All of the facilities remain offline, according to the Amazon Web Services health dashboard. The attack in Bahrain was launched "to identify the role of these centers in supporting the enemy's military and intelligence activities," Iran's Fars News Agency said on Telegram. In addition to structural damage, the data centers also experienced power disruptions and some water damage after firefighters worked to put out sparks and fire. Some popular AWS applications experienced "elevated error rates and degraded availability" due to the incident. AWS advised cloud customers to back up their data, consider migrating their workloads to other regions and direct traffic away from Bahrain and the UAE. Read more of this story at Slashdot.
