1:30a	Microsoft Has a New Trick To Improve Laptop Battery Life On Windows Microsoft is testing a new adaptive energy saver mode in Windows 11 that automatically turns energy saver on or off based on system workload instead of battery percentage, aiming to extend laptop battery life without dimming screen brightness. The feature is currently available to Windows Insider testers and expected to roll out later this year. The Verge reports: The energy saver mode in Windows 11 typically dims a display brightness by 30 percent, disables transparency effects, and stop apps running in the background. Non-critical Windows update downloads are also paused, and certain apps like OneDrive, OneNote, and Phone Link may not sync fully while energy saver is enabled. This new adaptive energy saver mode, which will only be available on devices with a battery, will automatically enable or disable without affecting screen brightness. That will make it less noticeable on devices like laptops, tablets, and handhelds. "Adaptive energy saver is an opt-in feature that automatically enables and disables energy saver, without changing screen brightness, based on the power state of the device and the current system load," explains Microsoft's Windows Insider team.

3:30a	California Set To Become First US State To Manage Power Outages With AI An anonymous reader quotes a report from MIT Technology Review: California's statewide power grid operator is poised to become the first in North America to deploy artificial intelligence to manage outages, MIT Technology Review has learned. "We wanted to modernize our grid operations. This fits in perfectly with that," says Gopakumar Gopinathan, a senior advisor on power system technologies at the California Independent System Operator -- known as the CAISO and pronounced KAI-so. "AI is already transforming different industries. But we haven't seen many examples of it being used in our industry." At the DTECH Midwest utility industry summit in Minneapolis on July 15, CAISO is set to announce a deal to run a pilot program using new AI software called Genie, from the energy-services giant OATI. The software uses generative AI to analyze and carry out real-time analyses for grid operators and comes with the potential to autonomously make decisions about key functions on the grid, a switch that might resemble going from uniformed traffic officers to sensor-equipped stoplights. But while CAISO may deliver electrons to cutting-edge Silicon Valley companies and laboratories, the actual task of managing the state's electrical system is surprisingly analog. Today, CAISO engineers scan outage reports for keywords about maintenance that's planned or in the works, read through the notes, and then load each item into the grid software system to run calculations on how a downed line or transformer might affect power supply. "Even if it takes you less than a minute to scan one on average, when you amplify that over 200 or 300 outages, it adds up," says Abhimanyu Thakur, OATI's vice president of platforms, visualization, and analytics. "Then different departments are doing it for their own respective keywords. Now we consolidate all of that into a single dictionary of keywords and AI can do this scan and generate a report proactively." If CAISO finds that Genie produces reliable, more efficient data analyses for managing outages, Gopinathan says, the operator may consider automating more functions on the grid. "After a few rounds of testing, I think we'll have an idea about what is the right time to call it successful or not," he says. Read more of this story at Slashdot. (Comment on this)
1:00p	CoreWeave Data Center To Double City's Power Needs An anonymous reader quotes a report from Bloomberg: CoreWeave is expanding a data center that is projected to double the electricity needs of a city near Dallas, another example of the strains that artificial intelligence workloads are placing on the US power supply. Local officials have grappled with how to handle the increased stress on the electricity grid from the project, according to a late 2024 presentation and emails seen by Bloomberg. The site is being developed by Core Scientific and will be used by OpenAI in Denton, Texas. Last week, CoreWeave announced it would acquire Core Scientific for about $9 billion, in part, to gain direct control of its data centers aimed at supplying AI work. Denton, about 50 miles northwest of Dallas, has almost doubled its population in the last 25 years to about 166,000 residents. To meet the spike in AI-related power demand, the city is passing on any extra costs to the data center operator and constructing additional grid infrastructure, Antonio Puente, general manager of local utility Denton Municipal Electric, said in an interview. "To serve the entire load from Core Scientific, we do have some transmission challenges," Puente said. "We will have to make some additional transmission investments." [...] Like some other large AI data center projects, the site in Denton was focused on cryptocurrency mining before pivoting to AI workloads in December. This transition means unrelenting power consumption -- the site will no longer curtail operations when power prices are high -- which will increase grid strain. "Now you're talking about a facility that has to have energy 24 hours a day, 365 days a year," Puente said. That challenge will be mitigated by the addition of backup generators and batteries, he added. Unlike many large projects, the Denton data center didn't receive local tax exemptions. Officials expect more than $600 million in property and sales tax from the data center expansion, more than double the costs it plans to incur, according to an analysis document seen by Bloomberg. It also anticipates that 135 new jobs will be created, according to the document. The Denton site, which is already being rented by CoreWeave, is Core Scientific's largest planned project at about 390 megawatts of power. It's "utilizing the majority of extra system capacity" in the city, wrote a utility executive in a January email seen by Bloomberg. Any additional large power users will exacerbate overloads on the grid, the executive added. "When fully built out, it will host one of the largest GPU clusters in North America," Core Scientific Chief Executive Officer Adam Sullivan said of the site during a May call. "Denton is a flagship facility." The report notes that Texas could face electricity shortages as soon as 2026 due to surging power demand from data centers, oil and gas operations, and crypto mining.

10:10p	KDE's Android TV Alternative, Plasma Bigscreen, Rises From the Dead Plasma Bigscreen, KDE's TV-focused interface, is being revived after years of inactivity thanks to contributor Devin, who overhauled the UI, redesigned the Settings app, improved app launching, and updated key modules. While still in progress -- with features like HDMI-CEC remote support and a virtual keyboard pending -- the project aims to rejoin KDE's official Plasma release schedule, potentially in version 6.5. Neowin reports: If you have not heard of it, Plasma Bigscreen is a Plasma shell for televisions, with original support for the now-defunct Mycroft AI assistant. It used to provide a simple launcher for apps and custom "Mycroft Skills" before development stalled, causing most distributions to drop it. The project was left behind during the big transition to Plasma 6 last year because no one had ported it in time for the megarelease. After a friend of his started poking at the code, Devin stepped in to tackle the much-needed work. [...] For anyone who wants to test this out, you can do as Devin did by installing Plasma Bigscreen on a Raspberry Pi using postmarketOS, though you would have to compile it yourself or pull from the nightly repos to get the latest changes. Applications like Kodi and VacuumTube (smart TV version of YouTube) work well with remote navigation, and some games like SuperTuxKart are playable. Controller support exists, but getting TV remotes to work over HDMI CEC is still untested. The project is far from finished; it still needs an arrow-navigable virtual keyboard and a clearer long-term direction now that Mycroft is gone. Still, the goal is to get it back into the official Plasma release schedule, possibly for version 6.5. Read more of this story at Slashdot. (Comment on this)
