    by BeauHD on 10/07/2026 at 6:00 pm

    Disney is exploring a free tier for Disney+ that would make some content available without a subscription. According to Nielsen data, the three largest free streamers accounted for 18.7% of watch time on U.S. TVs in April, up from 16.8% a year earlier and 12.7% in April 2024. Business Insider reports: Product and tech chief Adam Smith spoke about enabling free-tier content during a streaming town hall on Thursday afternoon, one staffer said. Smith didn't share a timeline for this initiative or a sense of the scope, this person added. A person familiar with Disney's streaming strategy said these talks are part of an ongoing discussion about concepts to better serve fans. Currently, the Disney+ and Hulu bundle costs $12.99 a month with ads or $19.99 without ads at full price. Read more of this story at Slashdot.

  • OpenAI to Retire ChatGPT Atlas Browser Less Than a Year After Launch
    by BeauHD on 10/07/2026 at 5:00 pm

    OpenAI is retiring its ChatGPT Atlas browser less than a year after launch. Going forward, its browsing features will be shifted into a redesigned ChatGPT desktop app that also combines Codex, a built-in browser, and "ChatGPT Work" for acting across apps and files. PCMag reports: OpenAI disclosed Atlas's retirement in a Thursday post introducing a more powerful ChatGPT desktop app, following reports that the company planned on turning it into a "superapp." [...] In a tweet, OpenAI product staff member James Sun added, "The current targeted date for deprecation is 8/9, and we'll share more information in the upcoming days both in-app and via email." The sunsetting means the Windows version of ChatGPT Atlas has been canceled, though the ChatGPT desktop app is still available on both Mac and Windows. The company is already touting the built-in browser, noting: "You can ask ChatGPT to research a market, compare sources, pull information from websites, or open and refine files from Google Workspace and Microsoft 365 inside the app. It can use the browser to bring in fresh context, take steps across web pages, and keep the work moving while you review and guide the result."

  • SAP Makes It Easier For Customers To Shop For Legacy Product Support, Ending EU Antitrust Probe
    by BeauHD on 10/07/2026 at 4:00 pm

    An anonymous reader quotes a report from The Register: The European Commission has ended an investigation into possible anticompetitive practices after SAP agreed to abolish reinstatement fees and reduce back-maintenance fees. The move could reduce barriers for customers considering third-party support for products nearing the end of their vendor support terms, including thousands of large businesses that rely on SAP ERP Central Component (ECC) to run their business operations. SAP's mainstream support for ECC ends in December 2027, while customers can opt for extended maintenance until December 2030 by paying an additional two percentage points on their maintenance fees. The most recent figures from Gartner showed that in Q4 2024 only 39 percent of worldwide ECC customers -- from a total of 35,000 -- had bought or subscribed to licenses to start their transition to SAP S/4HANA, the replacement ERP product. In September last year, the European Commission launched a formal investigation into SAP's behavior in the aftermarket for maintenance and support services in Europe. It said it was responding to concerns that SAP restricted competition in this crucial aftermarket by making it harder for rivals to compete, leaving European customers with fewer choices and higher costs. In October, SAP published its response. "SAP's commitments aim at improving the financial attractiveness for customers who wish to reinstate SAP maintenance and support services. Thus, future costs associated with reinstatement will not financially prevent customers from choosing to terminate SAP maintenance and support for a given period of time," the document said (PDF). SAP has now agreed to abolish reinstatement fees and reduce back maintenance fees charged to customers who return to SAP's support after a period of absence, the Commission confirmed. It also agreed to clarify conditions that allow customers to choose different maintenance and support service providers and different levels of support from SAP. The agreement is relevant to customers considering third-party support to extend their use of ECC beyond vendor maintenance. For example, last year, European retailer Kingfisher -- owner of well-known UK brands B&Q and Screwfix -- told a Gartner conference it had chosen Rimini Street to support ECC 6.0 because it saw insufficient value in migrating to SAP S/4HANA. [...] The commitments offered by SAP will remain in force globally for ten years. Read more of this story at Slashdot.

  • OpenAI's CEO of AGI Deployment, Fidji Simo, Is Stepping Down
    by BeauHD on 10/07/2026 at 3:00 pm

    OpenAI's CEO of AGI deployment, Fidji Simo, is stepping down from her full-time role and becoming a part-time adviser after taking extended medical leave for a chronic neuroimmune condition. "Three months ago, I had to go on medical leave after a severe exacerbation of a chronic illness I've lived with for seven years," Simo wrote in a post Thursday on X. "During that time, it became clear that the road to recovery would be much longer and more complex than I had anticipated -- and that I needed to focus on it fully." Wired reports: Simo joined OpenAI's board of directors in March 2024. The following year, CEO Sam Altman hired her to take on the product and business organizations so he could focus on research and the company's data center buildout. Previously, Simo was the CEO of Instacart and head of the Facebook app at Meta. Shortly before starting at OpenAI, Simo experienced a significant health relapse. She was diagnosed with postural tachycardia syndrome, or POTS, in 2019. "For my entire time here, I've postponed medical tests and new therapies to stay completely focused on the job and not miss a single day of work," she told OpenAI staff in a memo back in April, announcing her temporary departure. "It's now clear that I've pushed a little too far and I really need to try new interventions to stabilize my health." News of Simo's medical leave came amid a larger executive shakeup that saw Brad Lightcap, OpenAI's former COO, transition to a role overseeing special projects. OpenAI president and cofounder Greg Brockman took over OpenAI's product strategy. In the months since Simo stepped back from OpenAI, the company further reorganized its product teams, positioning Thibault Sottiaux as head of the company's core products, including ChatGPT.

  • Microsoft to Retire OWA Light Client In Exchange Server
    by BeauHD on 10/07/2026 at 12:00 pm

    Microsoft plans to disable and remove OWA Light, the lightweight Outlook Web Access client for Exchange Server, in an upcoming update expected in August 2026. The company says retiring the two-decade-old legacy interface will reduce attack surface and engineering complexity, pushing users to the modern Outlook on the web experience instead. BleepingComputer reports: "OWA Light was an important compatibility experience when the web needed it. Today, the full Outlook on the web experience is the right place for us to focus," the Exchange Team said on Wednesday. "Retiring OWA Light will help reduce legacy surface area, simplify ongoing engineering work, and allow us to continue improving the experience customers use every day." Microsoft introduced OWA Light roughly two decades ago as an alternative to OWA Premium, offering a simplified web interface for systems that didn't have Internet Explorer 6 or later installed or ran older web browsers. At the time, the company said that OWA Light offered a cleaner look, faster logon times on low-bandwidth Internet connections, and worked in locked-down browser modes (such as kiosks). Microsoft deprecated OWA Light as of August 19, 2024, and announced this week that the OWA Light experience will likely be removed from Exchange Server (on-premises) next month. "In an upcoming Exchange Server update (estimated in August 2026), we plan to disable and remove the OWA Light experience. After that change is introduced, users will no longer be able to choose or be redirected to OWA Light and should use the modern Outlook on the web experience instead."

  • Nobel-Winning US Chemist Will Move to China to Lead AI Institute
    by BeauHD on 10/07/2026 at 9:00 am

    Nobel-winning chemist Omar Yaghi is leaving UC Berkeley for China's Tsinghua University, where he will lead a new AI institute focused on accelerating the discovery of advanced materials. "Last week, Tsinghua University in Beijing welcomed Dr. Yaghi in an appointment ceremony, calling him one of the world's foremost chemists," reports The New York Times. "The university said he saw his new post as an opportunity 'not to slow down, not to repeat what has already been done, but to do science with more energy, more intensity, and more ambition than ever before.'" From the report: Dr. Yaghi was born in Amman, Jordan, to Palestinian refugees whose one-room home lacked electricity and running water. Early on, he became fascinated with a schoolbook's depiction of atomic building blocks. When he was 15, his father, a butcher, sent him to the United States. Last year, before flying to Stockholm to receive his Nobel Prize, Dr. Yaghi in an interview with The New York Times voiced concern about Mr. Trump's immigration policies, saying that they endanger the nation's system of universities, companies and governments that promote scientific excellence. "I think it's regrettable," he said of Mr. Trump's nationalism. "We have to know that people coming from different backgrounds improve the level for everybody involved," he added. "That's an amazing story. Great thinkers can improve not only the U.S. but the world." Dr. Yaghi joined the University of California, Berkeley, in 2012, and while there earned many awards for his scientific advances. He received his Nobel Prize for helping discover a world of chemistry in which molecular building blocks are assembled into structures that possess vast internal surface areas -- the largest of any known substance. His porous structures can act like sponges that readily absorb, store and release gases and vapors. He named them metal-organic frameworks. The metal atoms form an adjustable framework that can hold chemicals associated with life -- carbon atoms in particular. While deeply theoretical, the frameworks are so radical, innovative and flexible in nature that materials experts and companies foresee many commercial uses for them. The frameworks can, for instance, harvest water from desert air. In 2018, Dr. Yaghi's students at Berkeley tested the idea in the Mojave Desert in California, finding that a small passive harvester could each day produce nearly three cups of pure, drinkable water. The device is now nearing commercialization. In the interview with The Times, Dr. Yaghi credited the invention to his boyhood efforts to secure water for his family. The municipal pipes worked for only a few hours every week or two. That hardship, he added, shows how the diverse experiences of emigres can lead to unexpected breakthroughs. Dr. Yaghi has longstanding ties with Tsinghua University. In 2022, the Beijing school appointed him as an honorary professor and in that role he closely followed its work in chemistry, materials science and related disciplines. Now, on joining Tsinghua full time, Dr. Yaghi is being named as the head of a new A.I. institute for science research that will focus on the design and synthesis of new materials. Its underlying aim, the university said, is to "overcome the efficiency bottlenecks of traditional trial-and-error approaches" and shorten the usual cycles of discovery.
