New submitter greytree shares a report from Brown University: LUX-ZEPLIN, an experiment co-led by Brown University faculty and students, observed a particle interaction that could be interpreted as a signal from WIMPs, a dark matter candidate -- but researchers need more data to confirm. [...] The result does not yet meet the statistical threshold required to claim a discovery, but it is the most compelling hint of dark matter reported by the experiment to date. "We're very intrigued to see this event in the data, in the region where we expect dark matter to show up, and the competing backgrounds are very low," said Rick Gaitskell, a professor of physics at Brown University and the spokesperson for LZ. "With only one event, we don't want to get ahead of ourselves. We are not claiming to have seen dark matter. But we have seen something interesting that we want to share with the scientific community for their input." [...] If the anomalous event was caused by dark matter, the WIMP that generated it would likely have a mass of at least 200 GeV/c2 (gigaelectronvolts), or more than 200 times the mass of a proton. The LZ results have not reached "5-sigma" significance, the statistical threshold in physics that an event must reach to be considered a discovery. The new analysis is 2.6 sigma, meaning there is approximately a 0.5% chance that the event could be explained by known backgrounds. With additional data, researchers can test whether the finding continues to grow in significance or fades away. LZ has already accumulated the world's largest dark matter dataset and will continue to accrue WIMP search data at SURF, substantially improving their search statistics. JiJi Fan, an associate professor of physics at Brown not involved in the LZ experimental research but whose theoretical work is cited in the new LZ paper, said the new findings were "very intriguing." While the event recorded by LZ could not have been the simplest type of WIMP interaction, there are other types of possible interactions that could explain it, she said. Had a WIMP interacted in the simplest way at the high energy associated with this recent event, the detector would have recorded many recoil events at lower energies following the initial event. LZ recorded a single event, however, which requires an expanded theoretical explanation. "There are well-motivated theoretical extensions, including inelastic scattering and momentum-dependent elastic scattering, that could potentially account for this single event," Fan said. "This also sets up a target for on-going dark matter hunting, not only at direct detection experiments such as LZ but also at other complementary experimental frontiers." The results were presented in a scientific talk at the 2026 TeV Particle Astrophysics conference in Japan on Tuesday, Sept. 1. A paper detailing the finding can be found here (PDF).

GoPro plans to expand into AI infrastructure through a $285 million merger with optical-photonics company Starman Optical, whose transceivers will give the action-camera maker a foothold in the fast-growing data center market. GoPro also plans to push into defense, robotics, aerospace, and government markets while continuing its existing camera business. Engadget reports: Starman's optical transceivers are expected to fall under its umbrella, "extending the Company's reach into the large and rapidly growing market for AI infrastructure in optical transceivers," according to a press release. GoPro is also planning a push into the defense, government, robotics and aerospace sectors, bolstered by the combined company's IP, optics and imaging capabilities. [...] As Reuters notes, GoPro briefly reached a valuation of $4 billion on its first day as a publicly traded company in 2014. Its stock has struggled in recent years, but the share price received a boost on Monday when it was revealed that YouTuber and filmmaker Markiplier (Mark Fischbach) had become GoPro's largest individual shareholder after acquiring an 8.5 percent stake. The move follows a similar pivot made by the struggling shoe retailer Allbirds in April when it announced a pivot to AI compute infrastructure, sending the stock soaring more than 700%.

John Ternus has officially taken over as Apple CEO after 15 years under Tim Cook, stepping up from his role as senior vice president of hardware engineering. A 25-year Apple veteran who helped oversee products including AirPods, Apple Watch, Vision Pro, Apple silicon, and the new MacBook Neo, Ternus now inherits the challenge of pushing Apple forward in AI while Cook stays on as executive chairman. TechCrunch reports: Ternus has worked at Apple for nearly half of his life -- now 51 years old, he has been with the company for 25 years. He joined Apple's product design team in 2001 as only his second job out of college (his first was at a small maker of virtual-reality devices called Virtual Research Systems). By 2013, Ternus was a VP of hardware engineering and was promoted to the SVP role in 2021. [...] Ternus previously reported to Cook, who he considers a mentor, and led all of hardware engineering at Apple. That's a pretty big deal for a company that's known for ubiquitous hardware like the iPhone and the MacBook. [...] Ternus' earliest project at Apple involved scrutinizing parts for the Apple Cinema Display, an early desktop monitor. "At some point in my first year, I found myself at a supplier facility. I was far away from home. Well past midnight, I was using a magnifying glass to count the number of grooves on the head of a screw ... and I was arguing with the supplier because these parts had 35 grooves. They were supposed to have 25," Ternus recalled in his commencement speech. "I distinctly remember stepping back for a minute and thinking, 'What the hell am I doing? Is this normal?'" As Ternus climbed the corporate ladder, his responsibilities grew. He may no longer spend as much time analyzing screws, but he still seems to take pride in getting the little details right. In a recent interview, when Ternus was asked about his favorite memory of Steve Jobs, he mentioned the former Apple co-founder's attention to craftsmanship. "[Jobs] was moving a piece of furniture, a chest of drawers, and pulled it away from the wall and looked at the back and was just reflecting on, you know, that the carpenter who made it had made it beautiful," Ternus said. "It finished the back as beautifully as the rest of it, even though nobody was going to see it, right? And I think about that all the time because I think that perfectly exemplifies what we do here." From there, he went on to lead the hardware development behind products across the Apple ecosystem, overseeing launches like AirPods, Apple Watch, and the Vision Pro. He also had a hand in major technical upgrades at Apple, like Apple's transition from Intel chips to its own proprietary Apple silicon. Most recently, Ternus was involved in the production of the MacBook Neo, Apple's new, more affordable laptop model that lowers costs through some clever trade-offs in hardware design, like using an iPhone chip to power the device. "We never want to ship junk. We want to ship great products that have that Apple experience, that Apple quality. To do that with the Neo required building something completely new from the ground up ... leveraging both the technologies we'd been developing like Apple silicon, but also the kind of expertise that we've developed over many, many years of building Macs, and building phones, and building iPads, and all of these things," Ternus told Tom's Guide.

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.
