  • Samsung's Rolling Ballie Robot Indefinitely Shelved After Delays
    by msmash on 07/01/2026 at 7:21 pm

    Samsung Electronics has once again sidelined Ballie, a long-anticipated robot that was first announced six years ago but never released. Bloomberg News: The device -- designed to roll and roam throughout the home -- is completely absent from this week's CES, the biggest electronics trade show. And though Samsung said last year that Ballie was nearly ready for a retail release, the product is now unlikely to resurface soon. In an emailed statement, Samsung referred to Ballie as an "active innovation platform" within the company, rather than a forthcoming consumer device. "After multiple years of real-world testing, it continues to inform how Samsung designs spatially aware, context-driven experiences, particularly in areas like smart home intelligence, ambient AI and privacy-by-design," a Samsung spokesperson said in the statement.

  • The Inevitable Rise of the Art TV
    by msmash on 07/01/2026 at 6:39 pm

    Several years after Samsung introduced the Frame TV in 2017 -- a television designed to display fine art and resemble a framed painting when switched off -- competitors are finally catching up in meaningful numbers. Amazon announced the Ember Artline TV at CES 2026 this week, a $899 model that can display one of 2,000 works of art for free and includes an Alexa AI tool to recommend pieces suited to your room. Hisense unveiled its CanvasTV late last year, TCL has the NXTvision model, and LG has announced the Gallery TV for later this year. The surge in art-focused televisions comes down to two factors: smaller living spaces in cities where younger buyers lack dedicated rooms for large screens, and advances in matte screen technology that enable displays to absorb light like a canvas rather than reflect it like a window. Local dimming and improved backlighting processing allow these newer models to maintain their slim profiles for flush wall-mounting while delivering more realistic art reproduction than earlier edge-lit designs.

  • How Aviation Emissions Could Be Halved Without Cutting Journeys
    by msmash on 07/01/2026 at 6:01 pm

    Climate-heating emissions from aviation could be slashed in half -- without reducing passenger journeys -- by getting rid of premium seats, ensuring flights are near full and using the most efficient aircraft, according to analysis. The Guardian: These efficiency measures could be far more effective in tackling the fast-growing carbon footprint of flying than pledges to use "sustainable" fuels or controversial carbon offsets, the researchers said. They believe their study, which analysed more than 27m commercial flights out of approximately 35m in 2023, is the first to assess the variation in operational efficiency of flights across the globe. The study, led by Prof Stefan Gossling at Sweden's Linnaeus University, examined flights between 26,000 city pairs carrying 3.5 billion passengers across 6.8 trillion kilometers. First and business class passengers are responsible for more than three times the emissions of economy travelers, and up to 13 times more in the most spacious premium cabins. The average seat occupancy across all flights in 2023 was almost 80%. US airports accounted for a quarter of all aviation emissions and ran 14% more polluting than the global average. Atlanta and New York ranked among the least efficient airports overall, nearly 50% worse than top performers like Abu Dhabi and Madrid. Read more of this story at Slashdot.

  • Microsoft Cancels Plans To Rate Limit Exchange Online Bulk Emails
    by msmash on 07/01/2026 at 5:21 pm

    Microsoft has canceled plans to impose a daily limit of 2,000 external recipients on Exchange Online bulk email senders. From a report: The change was announced in April 2024, when Microsoft said that it would add new External Recipient Rate (ERR) limits starting January 2025 to fight spam, with plans to begin enforcing the limit on cloud-hosted mailboxes of existing tenants between July and December 2025. As explained last year, this new Mailbox External Recipient Rate Limit was designed to prevent Microsoft 365 customers from abusing Exchange Online resources and to restrict unfair usage. However, on Tuesday, Microsoft announced that the Exchange Online bulk emailing rate limit is being canceled indefinitely, following negative customer feedback. Read more of this story at Slashdot.

  • Logitech Caused Its Mice To Freak Out By Not Renewing a Certificate
    by msmash on 07/01/2026 at 4:41 pm

    An anonymous reader shares a report: If you're among the macOS users experiencing some weird issues with your Logitech mouse, then good news: Logitech has now released a fix. This comes after multiple Reddit users reported yesterday that Logi Options Plus -- the app required to manage and configure the controls on Logitech accessories -- had stopped working, preventing them from using customized scrolling features, button actions, and gestures. One Reddit user said that the scroll directions and extra buttons on their Logitech mouse "were not working as I intended" and that the Logi Options Plus app became stuck in a boot loop upon opening it to identify the cause. Logitech has since acknowledged the situation and said that its G Hub app -- a similar management software for gaming devices under the Logitech G brand -- was also affected. According to Logitech's support page, the problem was caused by "an expired certificate" required for the apps to run. Windows users were unaffected. The issues only impacted Mac users because macOS prevents certain applications from running if it doesn't detect a valid Developer ID certificate, something that has affected other apps in the past.

  • Dell Walks Back AI-First Messaging After Learning Consumers Don't Care
    by msmash on 07/01/2026 at 4:00 pm

    Dell's CES 2026 product briefing, PC Gamer writes, stood out from the relentless AI-focused presentations that have dominated tech events for years, as the company explicitly chose to downplay its AI messaging when announcing a refreshed XPS laptop lineup, new ultraslim and entry-level Alienware laptops, Area-51 desktop refreshes and several monitors. "One thing you'll notice is the message we delivered around our products was not AI-first," Dell head of product Kevin Terwilliger said during the presentation. "A bit of a shift from a year ago where we were all about the AI PC." The shift stems from Dell's observation that consumers simply aren't making purchasing decisions based on AI capabilities. "We're very focused on delivering upon the AI capabilities of a device -- in fact everything that we're announcing has an NPU in it -- but what we've learned over the course of this year, especially from a consumer perspective, is they're not buying based on AI," Terwilliger said. "In fact I think AI probably confuses them more than it helps them understand a specific outcome." Read more of this story at Slashdot.
