Sodium-Ion Battery Tested for Grid-Scale Storage in Wisconsin

"A new type of battery storage is about to be deployed on the Midwestern grid for the first time," reports Electrek: Sodium-ion battery storage manufacturer Peak Energy and global energy company RWE Americas will pilot a passively cooled sodium-ion battery system in eastern Wisconsin on the Midcontinent Independent System Operator network - the first sodium-ion deployment on that grid. Peak Energy says its technology is specifically designed for grid-scale storage and leverages sodium-ion chemistry's inherent stability. Unlike many lithium-ion systems, sodium-ion batteries don't require active cooling and can operate over a wide temperature range without losing performance. That simpler design could make a meaningful dent in the cost of storing electricity. According to Peak Energy, its system cuts the lifetime cost of stored energy by an average of $70 per kilowatt-hour. That's roughly half the total cost of a typical battery system today. The company says it achieves those savings by removing energy-hungry cooling systems, eliminating routine maintenance requirements, and reducing the need to overbuild storage capacity to account for battery degradation over time... If the Wisconsin pilot proves successful, it could open the door to wider adoption of sodium-ion batteries for large-scale energy storage across the US.

Android, Epic, and What's Really Behind Google's 'Existential' Threat to F-Droid

Starting in September, even Android developers not in Google's Play Store will still be required to register with Google to distribute their apps in Brazil, Singapore, Indonesia, and Thailand, with Google continuing "to roll out these requirements globally" four months later. Even developers distributing Android apps on the web for sideloading will be required to register, pay Google a $25 fee, and provide a government ID. But there's a new theory on what's secretly been motivating Google from an unnamed source in the "Keep Android Open" movement, writes long-time Slashdot reader destinyland: "You can't separate this really from their ongoing interactions with Epic and the settlement that they came to," they argue. Twelve days ago Epic Games and Google announced a new proposal for settling their long-running dispute over the legality of alternative app stores on Android phones. (Rather than agreeing to let third-party app stores into their Play Store, Google wants them to continue being sideloaded, promising in a blog post last week that they'll even offer a "more streamlined" and "simplified" sideloading alternative for rival app stores. "This Registered App Store program will begin outside of the US first, and we intend to bring it to the US as well, subject to court approval.") So "developer verification" could be Google's fallback plan if U.S. courts fail to approve this. "If the Google Play Store has to allow any third-party repository app store, Google essentially has given up all control of the apps. But if they're able to claw back that control by requiring that all developers, no matter how they distribute their apps, have to register with Google - have to agree to their Terms & Conditions, pay them money, provide identification - then they have a large degree of indirect control over any app that can be developed for the entire platform." But that plan threatens millions of people using the alternative F/OSS app distributor F-Droid, since Google also wants to have only one signature attached to Android apps. Marc Prud'hommeaux, a member of F-Droid's board of directors, says that "all of a sudden breaks all those versions of the application distributed through F-Droid or any other app store!" Prud'hommeaux says they've told Google's Android team "You know perfectly well that you're killing F-Droid!" creating an "existential" threat to an app distributor "that has existed happily for over 10 years." But good things started happening when he created the website Keep Android Open: There's now a "huge backlog" of signers for an Open Letter that already includes EFF, the Software Freedom Conservancy, and the Free Software Foundation. He believes Android's existing Play Protect security "is completely sufficient to handle the particular scenarios they claim that developer verification is meant to address"... The Keep Android Open site urges developers not to sign up for Android's early access program when it launches next week. (Instead, they're asking developers to respond to invites with an email about their concerns - and to spread the word to other developers and organizations in forums and social media posts.) There's also a petition at Change.org currently signed by 64,000 developers - adding 20,000 new signatures in the last 10 days. And "If you have an Android device, try installing F-Droid!" he adds. Google tracks how many people install these alternative app repositories, and a larger user base means greater consequences from any Android policy changes. Plus, installing F-Droid "might be refreshing!" Prud'hommeaux says. "You don't see all the advertisements and promotions and scam and crapware stuff that you see in the commercial app stores!"

FSF Threatens Anthropic Over Infringed Copyright: Share Your LLMs Freely

In 2024 Anthropic was sued over claims it infringed copyrights when training LLMs. But as they try to settle, they may have a problem. The Free Software Foundation announced Friday that Anthropic's training data apparently even included the book "Free as in Freedom: Richard Stallman's Crusade for Free Software" - for which the Free Software Foundation holds a copyright. It was published by O'Reilly and by the FSF under the GNU Free Documentation License (GNU FDL). This is a free license allowing use of the work for any purpose without payment. Obviously, the right thing to do is protect computing freedom: share complete training inputs with every user of the LLM, together with the complete model, training configuration settings, and the accompanying software source code. Therefore, we urge Anthropic and other LLM developers that train models using huge datasets downloaded from the Internet to provide these LLMs to their users in freedom. We are a small organization with limited resources and we have to pick our battles, but if the FSF were to participate in a lawsuit such as Bartz v. Anthropic and find our copyright and license violated, we would certainly request user freedom as compensation. "The FSF doesn't usually sue for copyright infringement," reads the headline on the FSF's announcement, "but when we do, we settle for freedom."

CSMWrap: make UEFI-only systems boot BIOS-based operating systems

What if you have a very modern machine that is entirely UEFI-only, meaning it has no compatibility support module and thus no way of enabling a legacy BIOS mode? Well, install a CSM as an EFI application, of course! CSMWrap is an EFI application designed to be a drop-in solution to enable legacy BIOS booting on modern UEFI-only (class 3) systems. It achieves this by wrapping a Compatibility Support Module (CSM) build of the SeaBIOS project as an out-of-firmware EFI application, effectively creating a compatibility layer for traditional PC BIOS operation. ↫ CSMWrap's GitHub page The need for this may not be immediately obvious, but here's the problem: if you want to run an older operating system that absolutely requires a traditional BIOS on a modern machine that only has UEFI without any CSM options (a class 3-machine), you won't be able to boot said operating system. CSMWrap is a possible solution, as it leverages innate EFI capabilities to run a CSM as an EFI application, thereby adding the CSM functionality back in. All you need to do is drop CSMWrap into /efi/boot on the same drive the operating system that needs BIOS to boot is on, and UEFI will list it as a bootable operating system. It does come with some limitations, however. For instance, one logical core of your processor will be taken up by CSMWrap and will be entirely unavailable to the booted BIOS-based operating system. In other words, this means you're going to need a processor with at least more than one logical processor (e.g., even a single-core machine with hyperthreading will work). It's also suggested to add a legacy-capable video card if you're using an operating system that doesn't support VESA BIOS extensions (e.g. anything older than NT). This is an incredibly neat idea, and even comes with advantages over built-in CSMs, since many of those are untested and riddled with issues. CSMWrap uses SeaBIOS, which is properly tested and generally a much better BIOS than whatever native CSMs contain. All in all, a great project.

Understanding SMF properties in Solaris-based operating systems

SMF is the illumos system for managing traditional Unix services (long-lived background processes, usually). It's quite rich in order to correctly accommodate a lot of different use cases. But it sometimes exposes that complexity to users even when they're trying to do something simple. In this post, I'll walk through an example using a demo service and the svcprop(1) tool to show the details. ↫ Dave Pacheco Soalris' system management facility or SMF is effectively Solaris' systemd, and this article provides a deeper insight into one of its features: properties. While using SMF and its suite of tools and commands for basic tasks is rather elementary and easy to get into - even I can do it - once you start to dive deeper into what is can do, things get complex and capable very fast.

Chrome comes to Linux on ARM64

Google has announced that it will release Chrome for Linux on ARM64 in the second quarter of this year. Launching Chrome for ARM64 Linux devices allows more users to enjoy the seamless integration of Google's most helpful services into their browser. This move addresses the growing demand for a browsing experience that combines the benefits of the open-source Chromium project with the Google ecosystem of apps and features. This release represents a significant undertaking to ensure that ARM64 Linux users receive the same secure, stable, and rich Chrome experience found on other platforms. ↫ The Chromium Blog While the idea of running Linux on Arm, only to defile it with something as unpleasant as Chrome seem entirely foreign to me, most normal people do actually use Google's browser. Having it available on Linux for Arm makes perfect sense, and might convince a few people to buy an Arm machine for Linux, assuming the platform can get its act together.
