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.

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.

Linux Kernel 7.0 Drops Outdated Mount API for Secure Modern Upgrade  WebProNews

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.

Nvidia Expands GeForce Now to Fire TV and Linux for 4K Ray Tracing  WebProNews

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."

Doubtful Linux can ever meaningfully challenge Windows 11? This new distro may change your mind  TechRadar

Microsoft's OneDrive cloud storage service has drawn renewed criticism for a particularly frustrating behavior pattern that can leave users without access to their local files after the service automatically activates during Windows updates. Author Jason Pargin recently outlined the problem: Windows updates can enable OneDrive backup without any plain-language warning or opt-out option, and the service then quietly begins uploading the contents of a user's computer to Microsoft's servers. The trouble begins when users attempt to disable OneDrive Backup. According to Pargin, turning off the feature can result in local files being deleted, leaving behind only a desktop icon labeled "Where are my files?" Users can redownload their files from Microsoft's servers, but attempting to then delete Microsoft's copies triggers another deletion of the local files. The only workaround requires users to hunt down YouTube tutorials that walk through the steps, as the relevant options are buried in menus and none clearly describe their function in plain English. Pargin compared the experience to a ransomware attack.

Polymarket is disputing that the mission to capture Nicolas Maduro constituted an invasion and said it will only settle a prediction contract if the US military takes control of Venezuelan territory. From a report: The decision by the prediction market has angered gamblers and added to the controversy surrounding a successful wager on the timing of Maduro's capture that netted more than $400,000 in winnings for a mystery trader. The dispute over the definition of "invade" highlights just one of the controversies faced by the mostly unregulated industry. Polymarket -- which only recently gained regulatory approval to operate legally in the US -- says on its website that it will resolve the "Will the US invade Venezuela by ... ?" contract if the US "commences a military offensive intended to establish control over any portion of Venezuela" by one of three dates. "The resolution source for this market will be a consensus of credible sources," it adds. Prediction platforms such as Polymarket do not typically make directional wagers in their own markets. Rather, they act as an intermediary matching long and short positions and adjudicating the outcome of events, collecting a fee in the process.
