An anonymous reader quotes a report from Reuters: The Trump administration on Monday issued a long-awaited proposed rule to open up retirement plans to alternative assets, paving the way for private equity and cryptocurrencies to be added to 401(k) accounts. The measure, announced by the U.S. Department of Labor, is intended to ease longstanding barriers to incorporating these less liquid and less transparent assets into American retirement plans. It follows an executive order from President Donald Trump last summer and could clear the way for alternative asset management firms to tap a large new source of capital. Industry groups have argued private market investments can enhance long-term returns and diversification for retirement savers, while skeptics warn higher fees, complexity and limited liquidity could limit those gains and pose risks for retail investors. Some private market funds that are already available to wealthier individual investors have shown signs of strain in recent months. Private credit funds known as business development companies have seen a wave of withdrawals. Treasury Secretary Scott Bessent said the proposed rule was "an initial step" and aimed to be "mindful of the importance of protecting retirement assets." The guidance lays out how plan trustees, who have a legal fiduciary duty to act in the best interest of members, can incorporate these assets. They would have to "objectively, thoroughly, and analytically consider, and make determinations on factors including performance, fees, liquidity, valuation, performance benchmarks, and complexity," the DOL said. Trustees who abide by them will be granted safe harbor that protects them from lawsuits, it added. The Supreme Court agreed earlier this year to hear one such case filed in 2019 by a former Intel employee claiming trustees made "imprudent" decisions by investing in hedge funds and private equity funds.

Researchers at the University of Waterloo say a new "quadratic quantum gravity" framework could explain the universe's rapid early expansion without adding extra ingredients to Einstein's theory by hand. The idea is especially notable because it makes testable predictions, including a minimum level of primordial gravitational waves that future experiments may be able to detect. "Even though this model deals with incredibly high energies, it leads to clear predictions that today's experiments can actually look for," said Dr. Niayesh Afshordi, professor of physics and astronomy at the University of Waterloo and Perimeter Institute (PI). "That direct link between quantum gravity and real data is rare and exciting." Phys.org reports: The research team found that the Big Bang's rapid early expansion can emerge naturally from this simple, consistent theory of quantum gravity, without adding any extra ingredients. This early burst of expansion, often called inflation, is a central idea in modern cosmology because it explains why the universe looks the way it does today. Their model also predicts a minimum amount of primordial gravitational waves, which are tiny ripples in spacetime geometry created in the first moments after the Big Bang. These signals may be detectable in upcoming experiments, offering a rare chance to test ideas about the universe's quantum origins. [...] The team plans to refine their predictions for upcoming experiments to explore how their framework connects to particle physics and other puzzles about the early universe. Their long-term goal is to strengthen the bridge between quantum gravity and observational cosmology. The research has been published in the journal Physical Review Letters.

Researchers found that common nitrile and latex lab gloves can shed stearate particles that closely resemble microplastics, potentially "increasing the risk of false positives when studying microplastic pollution," reports ScienceDaily. "We may be overestimating microplastics, but there should be none," said Anne McNeil, senior author of the study and U-M professor of chemistry, macromolecular science and engineering. "There's still a lot out there, and that's the problem." From the report: Researchers found that these gloves can unintentionally transfer particles onto lab tools used to analyze air, water, and other environmental samples. The contamination comes from stearates, which are not plastics but can closely resemble them during testing. Because of this, scientists may be detecting particles that are not true microplastics. To reduce this issue, U-M researchers Madeline Clough and Anne McNeil recommend using cleanroom gloves, which release far fewer particles. Stearates are salt-based, soap-like substances added to disposable gloves to help them separate easily from molds during manufacturing. However, their chemical similarity to certain plastics makes them difficult to distinguish in lab analyses, increasing the risk of false positives when studying microplastic pollution. "For microplastics researchers who have these impacted datasets, there's still hope to recover them and find a true quantity of microplastics," said researcher and recent doctoral graduate Madeline Clough. "This field is very challenging to work in because there's plastic everywhere," McNeil said. "But that's why we need chemists and people who understand chemical structure to be working in this field." The findings have been published in the journal Analytical Methods.

Why do so many people keep falling for the same trick over and over again? With an over $400 billion gap between the money invested in AI data centers and the actual revenue these products generate, Silicon Valley slowly returned to the tested and trusted playbook: advertising. Now, ads are starting to appear in pull requests generated by Copilot. According to Melbourne-based software developer Zach Manson, a team member used the AI to fix a simple typo in a pull request. Copilot did the job, but it also took the liberty of editing the PR's description to include this message: "⚡ Quickly spin up Copilot coding agent tasks from anywhere on your macOS or Windows machine with Raycast." ↫ David Uzondu at Neowin It turns out that Microsoft has added ads to over 1.5 million Copilot pull requests on GitHub, and they're even appearing on GitLab, one of the GitHub alternatives. The reasoning is clear, too, of course: "AI" companies and investors have poured ungodly amounts of money in "AI" that is impossible to recover, even with paying customers. As such, the logical next step is ads, and many "AI" companies are already starting to add advertising to their pachinko machines. It was only a matter of time before Copilot would start inserting ads into the pull requests it ejaculates over all kinds of projects. This isn't the first time a once-free service turns on its users, but it's definitely one of the quickest turnarounds I've ever seen. Usually it takes much longer before companies reach the stage of putting ads in their products to plug any financial bleeding, but with the amount of money poured into this useless black hole, it really shouldn't be surprising we're already there. I'm sure Copilot's competitors, like Claude, will soon follow suit. They're enshittifying Git, and developers are just letting it happen. No wonder worker exploitation is so rampant in Silicon Valley.

By reimplementing these features using capabilities, we made the kernel simpler by moving complex scheme and namespace management out of it which improved security and stability by reducing the attack surface and possible bugs. At the same time, we gained a means to support more sandboxing features using the CWD file descriptor. This project leads the way for future sandboxing support in Redox OS. As the OS continues to move toward capability-based security, it will be able to provide more modern security features. ↫ Ibuki Omatsu Redox seems to be making the right decisions at, crucially, the right time.

Of course, it was only a matter of time before the time-honoured tradition of the demoscene also got infected by "AI". For me personally, generative AI ruins much of the fun. I still enjoy creating pixel art and making little animations and demos. My own creative process remains satisfying as an isolated activity. Alas, obvious AI generated imagery - as well as middle-aged men plagiarizing other, sometimes much younger, hobbyist artists - makes me feel disappointed and empty. It's not as much about effort as it is about the loss of style and personality; soul, if you will. The result is defacement, to echo T. S. Eliot, rather than inspired improvement. Even in more elaborate AI-based works, it's hard to tell where the prompt ends and the pixelling begins. ↫ Carl Svensson A wonderful explanation of the rather unique views on originality, stealing, plagiarism, and related topics within the demoscene, which certainly diverge from many other places.

While starting this post I realized I have been maintaining personal infrastructure for over a decade! Most of the things I've self-hosted is been for personal uses. Email server, a blog, an IRC server, image hosting, RSS reader and so on. All of these things has all been a bit all over the place and never properly streamlined. Some has been in containers, some has just been flat files with a nginx service in front and some has been a random installed Debian package from somewhere I just forgot.
