New Thermal Material Provides 72% Better Cooling Than Conventional Paste

"Researchers at the University of Texas have unveiled a new thermal interface material that could revolutionize cooling, outperforming top liquid metal solutions by up to 72% in heat dissipation," writes Slashdot reader jjslash. "This breakthrough not only improves energy efficiency but also enables higher-density data center setups, cutting cooling costs and energy usage significantly." TechSpot reports: Thanks to a mechanochemically engineered combination of the liquid metal alloy Galinstan and ceramic aluminum nitride, this thermal interface material, or TIM, outperformed the best commercial liquid metal cooling products by a staggering 56-72% in lab tests. It allowed dissipation of up to 2,760 watts of heat from just a 16 square centimeter area. The material pulls this off by bridging the gap between the theoretical heat transfer limits of these materials and what's achieved in real products. Through mechanochemistry, the liquid metal and ceramic ingredients are mixed in an extremely controlled way, creating gradient interfaces that heat can flow across much more easily. Beyond just being better at cooling, the researchers claim that the higher performance reduces the energy needed to run cooling pumps and fans by up to 65%. It also unlocks the ability to cram more heat-generating processors into the same space without overheating issues. [...] As for how you can get your hands on the material: it's yet to make it out of the labs. The UT team has so far only tested it successfully at small scales but is now working on producing larger batches to put through real-world trials with data center partners. The material has been detailed in a paper published in the journal Nature Nanotechnology. Read more of this story at Slashdot.

Spotify’s Car Thing, Due For Bricking, Is Getting an Open Source Second Life

If you have Spotify's soon-to-be-bricked Car Thing, there are a few ways you can give it a new lease on life. YouTuber Dammit Jeff has showcased modifications to Car Thing that makes the device useful as a desktop music controller, customizable shortcut tool, or a simple digital clock. Ars Technica's Kevin Purdy reports: Spotify had previously posted the code for its uboot and kernel to GitHub, under the very unassuming name "spsgsb" and with no announcement (as discovered by Josh Hendrickson). Jeff has one idea why the streaming giant might not have made much noise about it: "The truth is, this thing isn't really great at running anything." It has half a gigabyte of memory, 4GB of internal storage, and a "really crappy processor" (Amlogic S905D2 SoC) and is mostly good for controlling music. How do you get in? The SoC has a built-in USB "burning mode," allowing for a connected computer, running the right toolkit, to open up root access and overwrite its firmware. Jeff has quite a few issues getting connected (check his video description for some guidance), but it's "drag and drop" once you're in. Jeff runs through a few of the most popular options for a repurposed Car Thing: - DeskThing, which largely makes Spotify desk-friendly, but adds a tiny app store for weather (including Jeff's own WeatherWave), clocks, and alternate music controls - GlanceThing, which keeps the music controls but also provides some Stream-Deck-like app-launching shortcuts for your main computer. - Nocturne, currently invite-only, is a wholly redesigned Spotify interface that restores all its Spotify functionality.

VMware Makes Workstation and Fusion Free For Everyone

An anonymous reader quotes a report from BleepingComputer: VMware has announced that its VMware Fusion and VMware Workstation desktop hypervisors are now free to everyone for commercial, educational, and personal use. In May, the company also made VMware Workstation Pro and Fusion Pro free for personal use, allowing students and home users to set up virtualized test labs and experiment with other OSs by running virtual machines and Kubernetes clusters on Windows, Linux, and macOS devices. Starting this week, the Pro versions and the two products will no longer be available under a paid subscription model. "Effective immediately, both VMware Fusion and VMware Workstation will transition away from the paid subscription model, meaning you can now utilize these tools without any cost. The paid versions of these offerings -- Workstation Pro and Fusion Pro -- are no longer available for purchase," said Broadcom product marketing director Himanshu Singh. "If you're currently under a commercial contract, you can rest easy knowing that your agreement will remain in effect until the end of your term. You will continue to receive the full level of service and enterprise-grade support as per your contract." While the free versions will include all the features available in the paid products, Broadcom will no longer provide users with support ticketing for troubleshooting. Broadcom plans to continue developing new features and improvements and ensure that updates are rolled out promptly. "We're actively investing in new features, usability improvements, and other valuable enhancements," Singh added. "Our engineering teams are committed to maintaining our high standards for stability, with timely updates and reliable performance."
