Submission + - AI Praise is No Recommendation: Code.org Touts Article by 'AI-Powered Strategist

Submitted by theodp
theodp writes: "The future of learning is digital," tech giant backed-and-led nonprofit Code.org posted Friday on LinkedIn. "A new report highlights how youth-focused coding platforms like Code.org are driving growth, opportunity, and access to essential skills for the next generation."

Sounds great, but the article linked to by Code.org — who Google CEO Sundar Pichai recently told the White House Task Force on AI Education is being given $3M by Google to transform its K-12 CS curriculum to make schoolchildren AI-savvy — is apparently AI-generated. The Future of Learning: Unlocking Long-Term Growth in Youth-Focused Coding Platforms is credited by AInvest.com to "Henry Rivers", who is described as "an AI-powered strategist designed for professionals and economically curious readers seeking investigative financial insight" who is "backed by a 32-billion-parameter hybrid model."

It's been long said that "Self-praise is no recommendation." How about AI praise?

Submission + - Austria's armed forces switch to LibreOffice (heise.de)

Submitted by alternative_right
alternative_right writes: Austria's armed forces have switched from Microsoft's Office programs to the open-source LibreOffice package. The reason for this is not to save on software license fees for around 16,000 workstations. "It was very important for us to show that we are doing this primarily (...) to strengthen our digital sovereignty, to maintain our independence in terms of ICT infrastructure and (...) to ensure that data is only processed in-house," emphasizes Michael Hillebrand from the Austrian Armed Forces' Directorate 6 ICT and Cyber.

This is because processing data in external clouds is out of the question for the Austrian Armed Forces, as Hillebrand explained on ORF radio station Ö1. It was already apparent five years ago that Microsoft Office would move to the cloud. Back then, in 2020, the decision-making process for the switch began and was completed in 2021.

Submission + - Zuckerberg Humiliated on Stage After AI-Powered Smart Glasses Keep Glitching (dnyuz.com)

Submitted by fjo3
fjo3 writes: Tech billionaire Mark Zuckerberg was humiliated onstage not once, but twice, as his attempts to showcase the brilliance of Meta’s new AI-powered glasses were met with dismal failure.

Speaking at the company’s annual Meta Connect conference, Zuckerberg introduced the company’s second-generation smart Ray-Bans and a new neural wristband, as part of his vision for an AI that serves people in real-time.

Business Insider reported the vision unraveled when the AI glitched moments after the request, ignoring basic instructions and insisting that the employee had “already combined these ingredients.”

Submission + - Tails 7.0 Linux distribution debuts with Debian 13 and GNOME 48 (nerds.xyz)

Submitted by BrianFagioli
BrianFagioli writes: Tails 7.0 has officially arrived, marking the first release of the privacy-focused, Linux-based operating system based on Debian 13 âoeTrixieâ and GNOME 48 âoeBengaluru.â This update delivers faster startup times, refreshed applications, and stronger hardware support.

One of the most noticeable improvements is boot speed. Thanks to a switch from xz to zstd compression, Tails now starts 10 to 15 seconds quicker on most machines. The tradeoff is a slightly larger image size, but for users with reliable USB sticks the difference in speed is worth it. The developers caution that low-quality USB drives could still cause slower boots.

Software updates are a major part of this release. GNOME Terminal has been replaced by GNOME Console, and GNOME Image Viewer has been swapped for GNOME Loupe. Key applications have been updated as well, including Tor Browser 14.5.7, Tor client 0.4.8.17, Thunderbird 128.14.0esr, Electrum 4.5.8, KeePassXC 2.7.10, GIMP 3.0.4, Inkscape 1.4, and Audacity 3.7.3. The Text Editor and Document Scanner also get substantial upgrades.

GNOME itself sees a wave of improvements. The Settings app now has redesigned sections for sound, accessibility, and input. New accessibility features include Overamplification and always-visible scrollbars. Other changes include a workspace indicator replacing the Activities button, better screen reader navigation, and an option to extend battery life in laptops. While GNOME 48 is a polished release, itâ(TM)s worth noting that GNOME 49 was released just yesterday, which makes Tails 7.0 feel slightly behind the curve from day one.

Some older tools have been removed, such as unar, aircrack-ng, and the Power Statistics utility, but alternatives remain. File Roller still handles most RAR archives, and aircrack-ng can be reinstalled if needed using Additional Software.

Under the hood, the Linux kernel has been updated to 6.12.43, boosting compatibility with newer graphics cards and Wi-Fi hardware. Memory requirements have also increased from 2GB to 3GB, though the developers expect this will affect very few users.

Tails 7.0 is a huge step for anyone who values privacy and security. With faster performance, updated apps, and better hardware support, it continues to be one of the most important Linux-based tools for staying anonymous online.

Submission + - C++ Commitee Prefers Bjarne Profiles Over Baxter Rustification

Submitted by robinsrowe
robinsrowe writes: No surprise, the C++ Committee is still trending toward C++ Profiles. It would have been a huge change had the Committee embraced Baxter's Rustification memory safety proposal. Would mean banning pointers. Making the C++ language much like Rust would deeply break every C++ program in the world. Article at TheRegister: “Rust-style safety model for C++ 'rejected' as profiles take priority” https://www.theregister.com/20...

The C++ standards committee abandoned a detailed proposal to create a rigorously safe subset of the language, according to the proposal's co-author, despite continuing anxiety about memory safety.

Article at Le Monde (in French): “The C++ standards committee rejected a proposal to create a secure subset of the language. Members prefer to focus on the Profiles framework pushed by C++ creator Bjarne Stroustrup.” https://www.lemondeinformatiqu...

"If you mark your code to apply a Profile, some features of the C/C++ language will stop working," he says. There is also a small problem, these guidelines were not integrated into version 26 of C++, but simply into a white paper. The controversy surrounding the security of C++ opens the door to another solution with the use of another language. The first advocated by several American authorities is Rust, but there is also Google's experimental Carbon project. Unveiled in 2022, it also aims to modernize C++.

If Profiles are eventually adopted, it may Balkanize C++ by dividing C++ into safe and unsafe subsets. C++ Profiles won't fix the issue of making C pointers memory safe. A proposal to implement pointer memory safety is TrapC, but for the C language, not C++. Some say make the switch to Rust, but that doesn't solve the safety problems lurking in billions of lines of existing C/C++ code.

Submission + - Synthetic magnetic fields steer light on a chip for faster communications (phys.org)

Submitted by alternative_right
alternative_right writes: The team achieved this by systematically altering the symmetry of tiny repeating units in silicon photonic crystals. Adjusting the degree of local asymmetry at each point allowed them to "design" pseudomagnetic fields with tailored spatial patterns, without breaking fundamental time-reversal symmetry. Both theoretical analysis and experiments confirmed that these engineered fields can guide and manipulate light in versatile ways.

To demonstrate practical applications, the researchers built two devices commonly used in integrated optics. One was a compact S-shaped waveguide bend that transmitted light with less than 1.83 decibels of signal loss. The other was a power splitter that divided light into two equal paths with low excess loss and minimal imbalance.

In a final test, the devices successfully transmitted a high-speed data stream at 140 gigabits per second using a standard telecommunications modulation format, showing that the technique is compatible with existing optical communication systems.

Submission + - Toxic "forever chemicals" found in 95% of beers tested in the U.S. (sciencedaily.com)

Submitted by alternative_right
alternative_right writes: Forever chemicals known as PFAS have turned up in an unexpected place: beer. Researchers tested 23 different beers from across the U.S. and found that 95% contained PFAS, with the highest concentrations showing up in regions with known water contamination. The findings reveal how pollution in municipal water supplies can infiltrate popular products, raising concerns for both consumers and brewers.

Submission + - Vicious Cycle Revealed: How Alcohol Helps Gut Bacteria Attack Your Liver (sciencealert.com)

Submitted by alternative_right
alternative_right writes: It's no secret that excessive alcohol consumption damages the liver, but a new study reveals a previously unknown vicious cycle that makes that damage worse. Chronic alcohol use makes it easier for bacteria to leak out of the gut and migrate to the liver, causing further harm.

The new study, led by scientists at the University of California San Diego, examined human liver biopsies as well as mouse models of alcohol-associated liver disease. The team found that chronic alcohol use impaired the production of a cellular signaling protein called mAChR4 in the small intestine.

Lower levels of this protein were found to interfere with the formation of what are called goblet cell-associated antigen passages (GAPs). These specialized structures play a key role in teaching the immune system to respond to microbes, particularly those that escape the gut into other parts of the body, where they don't belong.
