Longtime Slashdot reader fahrbot-bot shares a report from NewScientist: According to quantum chromodynamics (QCD) -- widely considered to be our best theory for describing the strong force, which binds quarks inside protons and neutrons -- even a perfect vacuum isn't truly empty. Instead, it is filled with short-lived disturbances in the underlying energy of space that flicker in and out of existence, known as virtual particles. Among them are quark-antiquark pairs. Under normal conditions, these fleeting pairs vanish almost as soon as they appear. But if enough energy is injected into a vacuum, QCD predicts they can be promoted into real, detectable particles with measurable mass. Now, the STAR collaboration -- an international team of physicists working at the Relativistic Heavy Ion Collider in Brookhaven National Laboratory in New York state -- has observed this process for the first time. The team smashed together high-energy protons in a vacuum, producing a spray of particles. Some of these particles should be quark-antiquark pairs pulled directly from the vacuum itself, but quarks can never exist alone and immediately combine into composite particles. Quarks and antiquarks are born with their spins correlated -- a shared quantum alignment inherited from the vacuum. The researchers found that this link persists even after the quarks and antiquarks become part of larger particles called hyperons, which decay in less than a tenth of a billionth of a second. Spotting these spin-aligned hyperons in the aftermath of the proton collisions allowed the researchers to confirm that the quarks within them came from the vacuum. The findings have been published in the journal Nature.

An anonymous reader quotes a report from NPR: Women in the U.S. gave birth to roughly 710,000 fewer children last year compared with the nation's peak in 2007, according to preliminary data released (PDF) this week by the Centers for Disease Control and Prevention. Lead researcher Brady Hamilton, a demographer with the CDC's National Center for Health Statistics, said the latest one percent drop in "general fertility" from 2024 to 2025 is part of a long-running downward trend. "Since 2007, there's been a decline in the general fertility rate [in the U.S.] of 23%," Hamilton told NPR. The impact of that change in real numbers is sizable: In 2007, there were 4,316,233 babies born. Last year, even though the nation's population as a whole is larger, there were only 3,606,400 newborns. There's no consensus over why women and couples have shifted their behavior so significantly. Some experts point to economic factors, others say cultural influences, and better access to education and contraception for women are driving the change. "We're seeing big drops in fertility rates for young women, teenagers and women in their 20s," said economist Martha Bailey, head of the California Center for Population Research at the University of California, Los Angeles. "What's not yet clear is whether or not those same women will go on to have children later on." "People are having the number of children they want and that they can afford at a time that makes the most sense for them," she said. "What I don't think anyone is in favor of is a Handmaid's Tale type policy regime, where we're trying to talk families into having children they don't want." One silver lining in the data is the 7% decline in teen pregnancies in 2025. Bianca Allison, pediatrician and associate professor at the University of North Carolina School of Medicine, said: "What is actually affecting the birth rates are likely lower rates of teen pregnancy overall, which is in the context of higher use of contraception and lower sexual activity for youth, and then also continued access to abortion care."

Update on what happened across the GNOME project in the week from April 03 to April 10.

GNOME Core Apps and Libraries Blueprint ↗

A markup language for app developers to create GTK user interfaces.

James Westman reports

blueprint-compiler is now available on PyPI. You can install it with pip install blueprint-compiler.

GNOME Circle Apps and Libraries Hieroglyphic ↗

Find LaTeX symbols

FineFindus reports

Hieroglyphic 2.3 is out now. Thanks to the exciting work done by Bnyro, Hieroglyphic can now also recognize Typst symbols (a modern alternative to LaTeX). Hardware-acceleration will now be preferred, when available, reducing power-consumption.

Download the latest version from FlatHub.

Amberol ↗

Plays music, and nothing else.

Emmanuele Bassi says

Amberol 2026.1 is out, using the GNOME 50 run time! This new release fixes a few issues when it comes to loading music, and has some small quality of life improvements in the UI, like: a more consistent visibility of the playlist panel when adding songs or searching; using the shortcuts dialog from libadwaita; and being able to open the file manager in the folder containing the current song. You can get Amberol on Flathub.

Third Party Projects

Alexander Vanhee says

A new version of Bazaar is out now. It features the ability to filter search results via a new popover and reworks the add-ons dialog to include a page that shows more information about a specific entry. If you try to open an add-on via the AppStream scheme, it will now display this page, which is useful when you want to redirect users to install an add-on from within your app.

Also, please take a look at the statistics dialog — it now features a cool gradient.

Check it out on Flathub

dabrain34 reports

GstPipelineStudio 0.5.1 is out now. It’s a great pleasure to announce this new version allowing to deal with DOT files directly. Check the project web page for more information or the following blog post for more details about the release.

Anton Isaiev announces

RustConn (connection manager for SSH, RDP, VNC, SPICE, Telnet, Serial, Kubernetes, MOSH, and Zero Trust protocols)

Versions 0.10.9–0.10.14 landed with a solid round of usability, security, and performance work.

Staying connected got easier. If an SSH session drops unexpectedly, RustConn now polls the host and reconnects on its own as soon as it’s back. Wake-on-LAN works the same way: send the magic packet and RustConn connects automatically once the machine boots. You can also right-click any connection to check if the host is online, and a new “Connect All” option opens every connection in a folder at once. For RDP there’s a Mouse Jiggler that keeps idle sessions alive.

Terminal Activity Monitor is a new per-session feature that watches for output activity or silence, which is handy for long-running jobs. You get notifications as tab icons, toasts, and desktop alerts when the window is in the background.

Security got a lot of attention. RDP now defaults to trust-on-first-use certificate validation instead of blindly accepting everything. Credentials for Bitwarden and 1Password are no longer visible in the process list. VNC passwords are zeroized on drop. Export files are written with owner-only permissions. Dangerous custom arguments are blocked for both VNC and FreeRDP viewers.

Hoop.dev joins as the 11th Zero Trust provider. There’s also a new custom SSH agent socket setting that lets Flatpak users connect through KeePassXC, Bitwarden, or GPG-based SSH agents, something the Flatpak sandbox previously made difficult.

Smoother on HiDPI and 4K. RDP frame rendering skips a 33 MB per-frame copy when the data is already in the right format. Highlight rules, search, and log sanitization patterns are compiled once instead of on every keystroke or terminal line.

GNOME HIG polish. Success notifications now use non-blocking toasts instead of modal dialogs. Sidebar context menus are native PopoverMenus with keyboard navigation and screen reader support. Translations completed for all 15 languages.

Project: https://github.com/totoshko88/RustConn Flatpak: https://flathub.org/en/apps/io.github.totoshko88.RustConn

Phosh ↗

A pure wayland shell for mobile devices.

Guido announces

Phosh 0.54 is out:

There’s now a notification when an app fails to start, the status bar can be extended via plugins, and the location quick toggle has a status page to set the maximum allowed accuracy.

On the compositor side we improved X11 support, making docked mode (aka convergence) with applications like emacs or ardour more fun to use.

The on screen keyboard Stevia now supports Japanese and Chinese input via UIM, has a new us+workman layout and automatic space handling can be disabled.

There’s more - see the full details here.

Documentation

Emmanuele Bassi announces

The GNOME User documentation project has been ported to use Meson for its configuration, build, and installation. The User documentation contains the desktop help and the system administration guide, and gets published on the user help website, as well as being available locally through the Help browser. The switch to Meson improved build times, and moved the tests and validation in the build system. There’s a whole new contribution guideline as well. If you want to help writing the GNOME documentation, join us in the Docs room on Matrix!

That’s all for this week!

See you next week, and be sure to stop by #thisweek:gnome.org with updates on your own projects!

I've finally gotten around to porting this blog over to Zola. I've been running on Jekyll for years now, after originally conceiving this blog in Middleman (and PHP initially). But time catches up with everything, and the friction of maintaining Ruby dependencies eventually got to me.

The Speed

I can't stress this enough — Zola is fast. Not "for a static site generator" fast. Just fast. My old Jekyll setup needed a good few seconds to rebuild after a change. Zola builds in milliseconds. The entire site rebuilds almost before I can release the key. It's not critical for a site that gets updated 5 times a year, but it's still impressive.

No Dependencies

This is the big one. Every time you leave a project alone for a few months and come back, you know it's not just going to magically work. The gem versions drift, Bundler gets confused, and suddenly you're down a rabbit hole of version conflicts. The only reason all our Jekyll projects were reasonably easy to work with was locking onto Ruby 3.1.2 using rvm. But at some point the layers of backwardism catch up with you.

Zola is a single binary. That's it. No bundle install, no Gemfile, no "works on my machine" prayers. Download, run, done. It even embeds everything — syntax highlighting, image processing, Sass compilation (if you haven't embraced the modern CSS light yet) — all built-in. The site builds the same on any machine with zero setup.

The Heritage

Zola started life as Gutenberg in 2015/2016, a learning project for Rust by Vincent Prouillet. He was using Hugo before, but hated the Go template engine. That spawned Tera, the Jinja2-inspired template engine that Zola uses.

The project got renamed to Zola in 2018 when the name conflicts with Project Gutenberg got too annoying. It's pure Rust, which means it's fast, memory-safe, and ships as a tiny static binary.

Asset Colocation

One thing I've always focused on for this blog architecture wise is the structure — images and media live right alongside the post, not stuffed into some shared /images/ folder somewhere like most Jekyll sites seem to do. Zola calls this "asset colocation," and it's a first-class feature. No plugins needed. Just put your images in the same folder as your index.md, reference them directly, and Zola handles the rest.

This is how I'd already been running things with Jekyll, so the port was refreshingly painless on that front.

The Templating

The main work was porting the templates. It was the main shostopper when Bilal suggested Zola a couple of years ago. I was hoping something with liquid to pop up, but it seems like people running their own blogs is not a Tik Tok trend. Zola uses Tera instead of Liquid. The syntax is similar enough to get by, but there's enough branches in your path to stumble on. The error messages actually make sense though and point you at the problem, which is a refreshing change from debugging broken Liquid includes.

The Improvements

Beyond speed, I've been cleaning up things the old theme dragged along:

• Dark mode without JavaScript: The original Klise theme injected a script to toggle themes. The new setup uses CSS-only theming via custom properties, no flash of wrong theme, no JS required.
• Legibility: I'm getting older, and apparently so are my readers. Font sizes bumped up, contrast dialled in. What looked crisp at 30 looks muddy at 50.

The site's cleaner now, light by default, faster to build, and I don't need to invoke Ruby just to write a blog post. The experience was so damn good, it motivated me to jump at a much larger project I'm hopefully going to post about next.

"One of VMware's biggest competitors, Nutanix, claims to have swiped tens of thousands of VMware customers," reports Ars Technica. They said higher prices, forced bundling, licensing changes, and more strained partner relationships have frustrated customers and driven them away from the leading virtualization firm. From the report: Speaking at a press briefing at Nutanix's .NEXT conference in Chicago this week, Nutanix CEO Rajiv Ramaswami said that "about 30,000 customers" have migrated from VMware to the rival platform, pointing to customer disapproval over Broadcom's VMware strategy, SDxCentral, a London-based IT publication, reported today. "I think there's no doubt that the customer sentiment continues to be negative about Broadcom," Ramaswami said, per SDxCentral. Nutanix hasn't specified how many of the customers that it got from VMware are SMBs or enterprise-sized; although, adoption is said to be strongest among mid-market customers as Nutanix also tries wooing larger customers, often by starting with partial deployments. During this week's press briefing, Ramaswami reportedly said that some of the customers that moved from VMware to Nutanix during the latter's most recent fiscal quarter represented Nutanix's "strongest quarterly new logo additions in eight years." "Most of the logos came from our typical VMware migrations on to the [hyperconverged infrastructure] platform," he said. During the Nutanix conference, Brandon Shaw, Nutanix VP and head of technology services, said that Western Union has been migrating from VMware to Nutanix for six months, The Register reported. The financial services company is moving 900 to 1,200 applications across 3,900 cores. Shaw said that Western Union has been exploring new IT suppliers to help it become more customer-focused. Despite Broadcom's history of "decent lines of communication" with Western Union, Shaw said that Western Union had "challenges partnering with them." Shaw also pointed to Broadcom's efforts to push customers to buy the VMware Cloud Foundation (VCF), despite the product often having more features than companies need and at high prices. Since moving to Nutanix, the Denver-headquartered financial firm is also benefiting from having more flexibility around workload locations, which is important since Western Union is in over 200 countries, The Register said.

BrianFagioli writes: Mozilla is accusing Microsoft of stacking the deck against Firefox, arguing that design choices in Windows steer users toward Edge even when they explicitly choose another browser. According to Mozilla, parts of Windows still open links in Edge regardless of the default browser setting, including results from the taskbar search and links launched from apps like Outlook and Teams. Mozilla says this means Firefox often never even gets the opportunity to handle those links, which quietly shifts user activity back into Microsoft's ecosystem. The company also points to Microsoft's aggressive rollout of Copilot as another example of platform power being used to push Microsoft services. Copilot appeared pinned to the taskbar, arrived automatically on many systems with Microsoft 365, and even received a dedicated keyboard key on some laptops. Mozilla argues that when the maker of the dominant desktop operating system promotes its own browser and AI tools at the system level, it becomes far harder for independent browsers like Firefox to compete.

Amazon CEO Andy Jassy says the company may eventually sell its Trainium AI chips directly to outside customers, not just through AWS, which would put Amazon in more direct competition with Nvidia. "There's so much demand for our chips that it's quite possible we'll sell racks of them to third parties in the future," Jassy wrote in his annual shareholder letter Thursday. He also revealed the company's chip business is already running at more than $20 billion annually, with demand so strong that current and even future generations are largely spoken for. Quartz reports: Access to Amazon's chips is currently limited to Amazon Web Services, with customers paying for cloud-based usage rather than owning any physical hardware. Selling to AWS and external customers alike, as standalone chipmakers do, would put annual revenue at around $50 billion, up from the $20 billion the company estimates for the year, Jassy said. The $20 billion figure spans three product lines: Trainium, the AI accelerator chip; Graviton, a general-purpose processor; and Nitro, a chip that helps run Amazon's EC2 server instances. All three are growing at triple-digit rates year over year, Jassy claimed in his letter. Jassy said demand for Trainium has outpaced supply at each generation. Trainium2 is essentially unavailable, with its entire allocated capacity spoken for. Trainium3 started reaching customers in early 2026, and reservations have filled nearly all available supply. Even Trainium4 -- which is not expected to reach wide release for another year and a half -- has substantial pre-orders committed. Jassy argued that a full-scale Trainium rollout could shave tens of billions off annual capital costs while meaningfully widening profit margin.

• Interested by TDF's sense of meritocracy - Italo is completely right that there are lots of vital non-coding contributions that have lots of merit. Discarding core contributor's views because you don't like their views is a different matter, and some contributions are really problematic. For a light-hearted view of how projects can protect themselves from an unbalanced community, complete with pictures see "My friends see me as something of a visionary." and Resolving apparently irreconcileable differences: "show me the road".

OpenAI is reportedly preparing a new cybersecurity product for a small group of partners, out of concern that a broader rollout could wreak havoc if it were released more widely. If that move sounds familiar, it's because Anthropic took a similar limited-release approach with its Mythos model and Project Glasswing initiative. Axios reports: OpenAI introduced its "Trusted Access for Cyber" pilot program in February after rolling out GPT-5.3-Codex, the company's most cyber-capable reasoning model. Organizations in the invite-only program are given access to "even more cyber capable or permissive models to accelerate legitimate defensive work," according to a blog post. At the time, OpenAI committed $10 million in API credits to participants. [...] Restricting the rollout of a new frontier model makes "more sense" if companies are concerned about models' ability to write new exploits -- rather than about their ability to find bugs in the first place, Stanislav Fort, CEO of security firm Aisle, told Axios. Staggering the release of new AI models looks a lot like how cybersecurity vendors currently handle the disclosure of security flaws in software, Lee added. "It's the same debate we've had for decades around responsible vulnerability disclosure," Lee said.

An anonymous reader quotes a report from CNN: A hacker has allegedly stolen a massive trove of sensitive data -- including highly classified defense documents and missile schematics -- from a state-run Chinese supercomputer in what could potentially constitute the largest known heist of data from China. The dataset, which allegedly contains more than 10 petabytes of sensitive information, is believed by experts to have been obtained from the National Supercomputing Center (NSCC) in Tianjin -- a centralized hub that provides infrastructure services for more than 6,000 clients across China, including advanced science and defense agencies. Cyber experts who have spoken to the alleged hacker and reviewed samples of the stolen data they posted online say they appeared to gain entry to the massive computer with comparative ease and were able to siphon out huge amounts of data over the course of multiple months without being detected. An account calling itself FlamingChina posted a sample of the alleged dataset on an anonymous Telegram channel on February 6, claiming it contained "research across various fields including aerospace engineering, military research, bioinformatics, fusion simulation and more." The group alleges the information is linked to "top organizations" including the Aviation Industry Corporation of China, the Commercial Aircraft Corporation of China, and the National University of Defense Technology. Cyber security experts who have reviewed the data say the group is offering a limited preview of the alleged dataset, for thousands of dollars, with full access priced at hundreds of thousands of dollars. Payment was requested in cryptocurrency. CNN cannot verify the origins of the alleged dataset and the claims made by FlamingChina, but spoke with multiple experts whose initial assessment of the leak indicated it was genuine. The alleged sample data appeared to include documents marked "secret" in Chinese, along with technical files, animated simulations and renderings of defense equipment including bombs and missiles.

After nearly 20 years on the platform, The Electronic Frontier Foundation (EFF) says it is leaving X. "This isn't a decision we made lightly, but it might be overdue," the digital rights group said. "The math hasn't worked out for a while now." From the report: We posted to Twitter (now known as X) five to ten times a day in 2018. Those tweets garnered somewhere between 50 and 100 million impressions per month. By 2024, our 2,500 X posts generated around 2 million impressions each month. Last year, our 1,500 posts earned roughly 13 million impressions for the entire year. To put it bluntly, an X post today receives less than 3% of the views a single tweet delivered seven years ago. [...] When you go online, your rights should go with you. X is no longer where the fight is happening. The platform Musk took over was imperfect but impactful. What exists today is something else: diminished, and increasingly de minimis. EFF takes on big fights, and we win. We do that by putting our time, skills, and our members' support where they will effect the most change. Right now, that means Bluesky, Mastodon, LinkedIn, Instagram, TikTok, Facebook, YouTube, and eff.org. We hope you follow us there and keep supporting the work we do. Our work protecting digital rights is needed more than ever before, and we're here to help you take back control.

Waymo is launching a pilot with cities and Google's Waze to share pothole data collected by its robotaxis, giving local transportation departments a new way to find and fix road damage more quickly. "We realized, hey, once we're at scale, we can actually share this data with cities, which is something that they've asked for and something that we collect at scale," said Arielle Fleisher, Waymo's policy development and research manager. "And so we figured out a way to make that happen." The Verge reports: Waymo uses its perception hardware, including cameras and radar, as well as accelerometers and the vehicle's physical feedback system, to log every pothole its vehicles encounter. These sensors detect physical changes to the road's surface, such as tilt and movement when the vehicle encounters irregularities. Originally, Waymo knew it needed the ability to detect potholes so it could ensure that its vehicles slowed down to avoid damage or injury to the passenger. Later, the company realized this could be invaluable data for cities, too. Under the new pilot program, that data will now be made available to cities' departments of transportation through a free-to-use Waze for Cities platform, which provides access to real-time, user-generated traffic data that officials can then use to make important decisions -- such as pothole repair. The platform also allows for Waze users to validate pothole locations through their own observations, decreasing the chances that city officials will be led astray by false positives. Currently, many cities rely on a patchwork of non-emergency 311 reports and manual inspections to address their pothole problems. Waymo developed this pilot program after collecting years of feedback from city officials about the state of their highways and surface streets. The company is launching the new pilot in the San Francisco Bay Area, as well as Los Angeles, Phoenix, Austin, and Atlanta, where Waymo says it has already helped the city identify approximately 500 potholes. Fleisher said that Waymo would be open to expanding the project to other street maladies based on further feedback from officials. The company is eager to learn what other types of street condition or safety data might be valuable, she said. "We want to be responsive to cities," Fleisher said. "They are interested in safer streets and potholes are really a tough challenge for cities. So we really wanted to meet that need as part of our desire to be a good partner and to ultimately advance our goal for safer streets."
