America's public education system has become "an avenue for multitrillion-dollar companies to enact their agendas," argues a NewYork Times reporter who's covered that tech industry influence for over 10 years. Big tech companies "advocate for new laws to require schools to teach industry-aligned subjects. They sit on committees that help shape learning standards for public school students..." The reporter concludes that "Silicon Valley's efforts to capture the attention of education professionals and provide student training materials can also double as marketing or indoctrination." They enable some of the most powerful corporations on the planet to spin rosy technology stories for administrators, teachers and students, giving them a sanitized view of industry practices and product risks. Many parents would likely object if, say, Exxon Mobil wrote their children's environmental science curriculum. Or if Purdue Pharma trained their children's biology teachers. Yet, over the last decade, schools have often embraced the technology industry in similar ways with few questions asked. The article excerpts the soon-to-be-released book " Coding Kids: Big Tech's Battle to Remake Public Schools," with the reporter adding more thoughts on LinkedIn: Every few years, Silicon Valley has urged American public schools to quickly adopt the latest technology or teach the latest tech subject: Big Data analytics; laptops for every child; algorithm-driven math and reading apps; compter programming; virtual reality. And each time the urgent arguments sounded remarkably similar: if schools just adopted the latest tech tool, or taught the latest tech subject, it would democratize learning for every child and equip students with valuable career skills. Despite good intentions, "today we know some of those classroom tech drives did not exactly pan out as advertised." Now some of the same companies that urged schools to provide laptops and coding lessons are employing similar arguments to urge schools to quickly adopt A.I. tools. I've spent years covering Chromebooks and student chatbot use. And I'm troubled by our collective amnesia around school tech. Thanks to long-time Slashdot reader theodp for sharing the article.

ScienceDaily reports: A microchip about the size of a grain of rice can generate a highly organized "rainbow" of light, a capability that could eventually support faster, higher-capacity 6G communications and extremely precise timing for quantum technologies. Physicists at Loughborough University, working with an international research team, demonstrated a system that produces a series of precisely spaced light frequencies. Those optical frequencies can then be converted into multiple high-frequency electromagnetic signals known as millimeter waves. Millimeter waves are attracting growing interest for future communications because they can provide considerably more bandwidth, giving networks more room to transmit data. A major obstacle, however, has been producing these signals with the precision and stability required for advanced applications... "They could ultimately contribute to faster, higher capacity 6G networks," [said Dr. Luke Peters, of Loughborough University's Emergent Photonics Research Centre], "but the potential goes far beyond communications. These frequencies could also be used in radar systems as well as spectroscopy and astronomical instruments, helping scientists study materials and make extremely precise measurements of the universe. "These applications are still some way off, and there are challenges to overcome before the technology can be used in real-world systems - but our latest work has tackled a major one..." A microcomb generates an extremely precise set of light frequencies arranged somewhat like the colors in a rainbow, although the light itself is invisible to the human eye. A specialized antenna can then convert those optical frequencies into millimeter waves. Earlier research demonstrated that microcombs could produce a single precise millimeter wave frequency. Generating many frequencies simultaneously could be far more useful because each could potentially serve as a separate channel for transmitting information at the same time. Achieving that, however, requires a microcomb with exceptional stability and signal quality. In a new Nature Communications paper, the Loughborough led researchers report a system capable of doing exactly that. Their system connects its chip-based microresonator to a much larger loop of optical fiber where laser light continuously travels through both parts of the system, according to the article. "The team is now investigating how the microcomb system could eventually move from a laboratory experiment into practical technology."

Citrix's Desktop as a Service (DaaS) product includes a lightweight, hardened second operating system called UniconOS (once called "eLux") to offer Windows customers a write-protected file system Citrix says is secure against computer viruses and other malware. Nerds.xyz reports: According to the company, the environment remains isolated from the Windows filesystem and uses Secure Boot protections covering the shim, bootloader, kernel, and initial RAM filesystem. That separation matters when ransomware encrypts Windows or a faulty update leaves the operating system trapped in a boot loop. Instead of repairing Windows immediately, an employee can boot into UniconOS and use Citrix DaaS to access virtual applications and desktops. Citrix SecurAccess with Chrome Enterprise provides access to internal web applications under the organization's existing security policies. In other words, UniconOS does not actually fix the damaged Windows installation. It gives employees another route to their applications while the IT department investigates or repairs Windows... [T]he installer shrinks the Windows volume, creates a new partition, copies UniconOS onto it, and registers the necessary boot entries. Windows remains the default operating system during ordinary use, although administrators can configure boot delays and fallback behavior... The approach could prove useful following a widespread ransomware attack or another defective Windows update resembling the CrowdStrike incident of 2024. Recovery would happen independently on every compatible endpoint instead of requiring IT employees to physically handle thousands of computers.

Virtually all laptop speakers suck. It's the one area where even really expensive laptops tend to fall on their ass, leaving users with a tinny, harsh, and hollow sound experience. While you can't exactly overcome physics - laptop speakers are necessarily small and thus just cannot ever sound as good as proper speakers - there's a lot you can do with proper tuning and software magic. If you're a desktop Linux user, you actually already possess all the plumbing needed to fix your audio; it's just not exposed to you in any way. Luckily, an application called EasyEffects allows you to actually make use of desktop Linux' advanced audio features to massively improve the sound quality of your laptop's speakers. EasyEffects' own description on its GitHub page doesn't really explain what it does or what it's capable of, so here's the description from Wikipedia instead. EasyEffects uses PipeWire to process incoming and outgoing audio streams independently and can apply various sound effects in the form of plug-ins made by different developer teams such as Calf Studio Gear, MDA.LV2 and GStreamer. All plugins have their own presets and can be applicable inside the suite rather than having to use a different mixer or executing a script from the command line. Available output effects are limiter, auto volume, compressor of dynamic range, filter, 30 bands parametric equalizer, bass enhancer, exciter, reverbation, crossfeed, delay, maximizer and spectrum analyzer. Available input effects are WebRTC, limiter, compressor, filter, equalizer, de-esser, reverbation, pitch shift and spectrum analyzer. ↫ EasEffects' Wikipedia page None of this matters, and you can forget everything from these two paragraphs. What matters is that using EasyEffects, you can tune the audio coming out of your speakers to make them sound a lot better. The few laptops on the market that do have decent audio - MacBooks, some Dell XPS laptops, and surely a few more - aren't magically defying physics. While they probably do have objectively higher-quality speakers, the main difference between those laptops and laptops with crappy-sounding speakers is that the former come with built-in tuning from the factory to make them sound much better than they would without any software trickery. If you know your way around audio, you can very much use EasyEffects and tune your laptop speakers from scratch to massively improve how they sound. However, that requires time, experience, knowledge, and expertise that most people lack, including myself. Lucky for us, though, there are countless downloadable presets out there for EasyEffects designed specifically to make laptops sound better. In an ideal world, you'd pick a preset created specifically for your laptop make and model, but odds are you won't find one, so for most laptops you'll have to settle for a generic preset that tries to do its best. I've long settled on the Advanced Auto Gain.json preset from JackHack96, which greatly improves the audio performance on any laptops I've tried it on, but of course, there's countless other presets for you to try to see if there's anything that suits your particular laptop and ears better. Getting all of this up and running is really easy. EasyEffects is most likely packaged by your Linux distribution, and the latest version is always available as a Flatpak from Flathub. Download the preset(s) you want to try, copy them either to ~/.config/easyeffects (if you use your distribution's package) or to ~/.var/app/com.github.wwmm.easyeffects/data/easyeffects/output/ (if you use the Flatpak version). They'll show up right away in the Presets tab in EasyEffects, ready to be turned on and off whenever you want, making it very easy to compare and contrast to find the one you like best. EasyEffects can live in your system tray giving you easy access to your presets without having to open the main window, and it can be set to start automatically at boot. EasyEffects can also be turned on and off on the fly. There's obvious downsides to all of this, too, of course. First, since you're most likely going to be using a generic preset not specifically crafted for your laptop, there's no guarantee the results will be positive for you. Second, not every preset is ideal for every type of audio. Most of my audio consists of YouTube videos with mostly speech; if you listen mostly to music, different presets may yield better results. Third, audio quality is deeply subjective, and what sounds good to my ears may sound like total garbage to yours. Fourth, EasyEffects does take up a tiny fraction of CPU power (I'm talking 0.1-0.2% according to KDE's System Monitor), but I have never seen it have any noticeable performance impact on anything. Even the generic preset I use makes such a massive difference for me on every laptop I've ever tried it on, that I've become convinced EasyEffects and a few of the generic presets should be installed by default by any desktop-oriented Linux distribution. On top of that, Linux laptops OEMs like System76, Nova Custom, Star Labs, and so on, should really take the time to create proper presets for their laptops to improve their sound quality out of the box. I feel like if you're already designing and selling laptops, you probably also have the skills and means to create a decent preset. In fact, I'd take it a step further and urge desktop environments like KDE and GNOME to properly integrate EasyEffects into their sound settings. They shouldn't include the entire application and its user interface, but should make it so that you can configure and manage presets right from the sound settings panels, and switch between presets from their volume applets (as well as turn it off entirely, of course). This would leave the full EasyEffects application for people who need more control, manual tuning, and more advanced features. There's absolutely no reason why speakers on Linux laptops should sound tinny, harsh, and hollow. The Linux desktop has all the technologies and features built right in to make speakers sound much better than they do without any tuning,

Built on a 2 nanometer technology node, the processor's design will contain 11 high-performance cores operating at more than 5.7 GHz, AI inference accelerators for in-transaction fraud detection, a dedicated on-chip data processing unit for I/O acceleration, and a large cache architecture for demanding enterprise workloads. The chip is architected to not contain separate Arm and IBM cores: each processor core can natively execute Arm and IBM Z, or Arm and LinuxONE, instructions concurrently while prioritizing the platform's established performance, security, encryption, and availability characteristics. IBM Z and LinuxONE platforms are capable of scaling to hundreds of cores and tens of terabytes of memory. ↫ IBM press release IBM is still doing some amazing chip architecture design. ServeTheHome has more details of how this works: A key choice here is that IBM implemented AArch64 in full hardware rather than through translation. This design uses a little-endian Arm implementation alongside big-endian z/Architecture, with AArch64 v9.3, SVE and SVE2 support, and 2,792 implemented AArch64 instructions. IBM also claims Arm SystemReady compliance, which matters for how much off-the-shelf Arm software this core can absorb. This is absolutely crazy technology. Arm software sees a native Arm processor. Arm runs unmodified, out-of-the-box, and onto a standard Arm platform. IBM said the 2792 AArch64 instructions are more than twice the Z instructions. IBM made a funny quip about "reduced" in RISC. ↫ Patrick Kennedy at ServeTheHome This is bonkers technology. We can only dream of this ever serving a home.

It's always a special day on OSNews when Haiku has a new release. While OSNews was founded in 1997, it wasn't until 2001, when Eugenia took over and relaunched the site, that we really got going. Eugenia came from BeNews, a popular BeOS news website, which shut down in the wake of Be, Inc's infamous "focus shift" away from BeOS as a general purpose desktop operating system. BeOS continues to have a special place on OSNews ever since. Today marks the release of Haiku R1/beta6, the first official Haiku release in two years. As such, this new beta covers a monumental amount of progress since beta5, progress I've reported on diligently. The highlights of this new beta include a port of Firefox (including branding) and many of its forks, much improve support for Qemu, a new memory allocated largely based on the one from OpenBSD, and improved support for various filesystems. Of course, there's a massive list of performance improvements, memory management changes, as well as a truly massive number of new application ports. It's important to note, as I usually do, that while these Haiku beta releases serve as patches of calm in rough seas, Haiku is generally stable and capable enough that using the project's nightly releases is usually a totally acceptable way of installing and running the operating system. If you're not comfortable running nightly releases, however, and haven't tried Haiku since the previous beta, you're in for a massive overall improvement. Everybody loves Haiku.

Over the last few weeks, we have been doing research on the integration of our official distribution packages when installed on a target system. In this context we have been looking at the current uses of alpm-install-scriptlet(5) files and alpm-hooks(5) in around 120 package source repositories (alpm-source-repo(7)) to better understand the underlying functionality and use-cases these two integrations offer and target. In this article we are going to look at how these two systems work, how Arch Linux is currently using them and attempt to provide suggestions for when to use which.

This is just a short note on my blog that I have resigned from Arch Linux a package maintainer, developer and security team. I've spent around 10 years as an AUR maintainer, security team, Package Maintainer and then Developer. I implemented support for debug packages, did the initial POC work that would become the git migration and even somehow managed to pull of an online conference during The Plague with the help of others.
