An anonymous reader quotes a report from The Guardian: A common sweetener used in products such as chewing gum, toothpaste, jam, yoghurts and ice-cream has been linked to an increased risk of strokes, heart attacks and death. Xylitol is a sugar alcohol present in some natural foods in very low amounts. It is also added -- often in amounts 1,000 times higher -- to artificially sweeten foods, beverages and oral care products. Despite its growing use, the long-term health impacts of xylitol have never been widely studied. In the largest study of its kind, researchers found high blood levels of xylitol were associated with an increased risk of major adverse cardiovascular events. The findings were presented in Munich at the European Society of Cardiology (ESC) annual congress, the world's largest heart conference. Researchers looked at 17,710 people and compared the 25% with the highest levels of xylitol in their blood against the 25% with the lowest. Those who had the highest amount were 57% more likely to die or suffer a heart attack or stroke, than those with the least, within six years. Even after 30 years, they were still 18% more likely to have suffered one of these cardiac events. Taken with data from the middle quartiles, the results from both cohorts suggested a dose-dependent relationship: the higher the xylitol blood levels, the higher the cardiovascular event rate. Furthermore, the researchers showed that there was consistent increase in cardiovascular events with xylitol irrespective of baseline characteristics, such as age and sex. The researchers also highlighted that the association was independent of underlying factors such as body mass index, hypertension, diabetes and lipid levels, which might predispose people to low-calorie products.

SpaceX is significantly reducing Falcon 9 launches from Florida this year, ending the Space Coast's decade-long run as the world's busiest spaceport as more missions shift to Vandenberg Space Force Base in California. The slowdown is expected to continue until Starship begins flying regularly from Florida. Longtime Slashdot reader schwit1 shares a report from Ars Technica: A Falcon 9 launch early Tuesday was the last planned Starlink mission from Cape Canaveral until SpaceX begins flying Starship missions from Florida, according to Kiko Dontchev, the company's vice president of launch. For at least the rest of the year, and maybe longer, this means the launch rate at the Florida spaceport will drop from eight or nine per month to perhaps two per month. It wasn't long ago when two launches per month was the norm, an indication of just how quickly SpaceX's launch cadence has grown. Cape Canaveral and Kennedy Space Center sit on adjoining property and share the same range on Florida's east coast, so it is worth considering them a single spaceport. The last time the Florida spaceport did not lead the world in space launches was in 2015. "From here on, Starlink missions out of Florida will fly on Starship," Dontchev wrote on X. "The West Coast team will continue regularly launching Starlink from Vandenberg." "Yep, that'll be louder -- but everybody knows the real action will be in Louisiana, starting in 2029 or so," writes schwit1. SpaceX on Tuesday announced plans to spend up to $100 billion building a new Starship launch facility in Vermilion Parish, Louisiana, which the state says could eventually "support thousands of launches annually."

President Trump awarded the four-member Artemis II crew the Congressional Space Medal of Honor and signed an executive order directing the creation of a new U.S. Space Academy. The proposed academy would train engineers, scientists, technicians, operators, and astronauts for NASA, the Space Force, and the commercial space industry. Houston Public Media reports: The Artemis II crew -- NASA's Reid Wiseman, Victor Glover, Christina Koch, and the Canadian Space Agency's Jeremy Hansen -- retraced history as they flew around the moon and back in April, the first time humans have been in lunar territory since the 1970s. He had previously hosted the crew members at the White House following their mission and called them during the mission while the crew was tens of thousands of miles away. "The one thing that really sticks out to us [from that call] is you said how proud you are and how proud our nation is for the job that we've just accomplished," Wiseman said during Friday's ceremony. "And for us, that is what we set out to do. We wanted to inspire this nation to learn." During the ceremony, Trump also signed an executive order to create the "United States Space Academy." Under the order, a Presidential Commission on the U.S. Space Academy has 120 days to create a report with guidelines for the U.S. Space Academy. The Commission will include NASA Administrator Jared Isaacman as its Chair, as well as other NASA and space officials. Secretary of Defense Pete Hegseth, Trump's Chief of Staff Susie Wiles, and Michael Kratsios, assistant to the president for science and technology. In effect, it allows the Trump Administration to build the U.S. Space Academy to its liking. "It will serve both the United States Space Force as well as NASA and the civilian spaceflight industry," Trump said. "And it will attract, train, graduate the very best that our nation and our nation really has to offer." As for where the academy will be located, Trump said he was "going to be choosing a location very shortly."

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. Learning about alpm-hooks(5) and alpm-install-scriptlet(5) files …

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.
