An anonymous reader quotes a report from U.S. News & World Report: U.S. health officials plan a new study investigating whether radiation from cellphones may affect human health. A spokesperson for the U.S. Department of Health and Human Services (HHS) said the research will examine electromagnetic radiation and possible gaps in current science. The initiative stems from numerous concerns raised by Health Secretary Robert F. Kennedy Jr., who has linked cellphone use to neurological damage and cancer. "The [U.S. Food and Drug Administration] removed webpages with old conclusions about cell phone radiation while HHS undertakes a study on electromagnetic radiation and health research to identify gaps in knowledge, including on new technologies, to ensure safety and efficacy," HHS spokesman Andrew Nixon said. He added that the study was directed in a strategy report from the president's Make America Healthy Again Commission. Some webpages from the FDA and the U.S. Centers for Disease Control and Prevention say current research does not show clear harm from cellphone radiation. The National Cancer Institute, which is part of the National Institutes of Health, says that "evidence to date suggests that cellphone use does not cause brain or other kinds of cancer in humans.".

The UK government has launched a public consultation on whether to ban social media use for children under 16, drawing inspiration from Australia's recently enacted age-based restrictions. "It would also explore how to enforce that limit, how to limit tech companies from being able to access children's data and how to limit 'infinite scrolling,' as well as access to addictive online tools," reports Engadget. "In addition to seeking feedback from parents and young people themselves, the country's ministers are going to visit Australia to see the effects of the country's social media ban for kids, according to Financial Times."

A PwC survey of more than 4,500 CEOs found that over half report no revenue growth or cost savings from their AI investments so far, despite massive spending. Of the 4,454 business leaders surveyed, only 12% saw both lower costs and higher revenue, while 56% saw neither benefit. "26% saw reduced costs, but nearly as many experienced cost increases," adds The Register. From the report: AI adoption remains limited. Even in top use cases like demand generation (22 percent), support services (20 percent), and product development (19 percent), only a minority are deploying AI extensively. Last year, a separate PwC study found that only 14 percent of workers indicated they were using generative AI daily in their work. Despite the CEOs' repsonses, PwC concludes more investment is required. It claims that "isolated, tactical AI projects" often don't deliver measurable value, and that tangible returns instead come from enterprise-wide deployments consistent with business strategy. [...] In terms of the broader picture, PwC says it found CEO confidence has hit a five-year low, with only 30 percent optimistic about revenue growth (down from 38 percent last year). This points to growing geopolitical risk and intensifying cyber threats, as well as uncertainty over the benefits and downsides of AI. Unsurprisingly, concern remains over tariffs as the Trump administration continues its erratic approach to policy, with almost a third of company chiefs saying tariffs are expected to reduce their company's profit margin in the year ahead. In the U.S., 22 percent indicate their corporation is highly or extremely exposed to tariffs. PwC warns that companies avoiding major investments due to geopolitical uncertainty underperform peers by two percentage points in growth and three points in profit margins.

I totally forgot you could do this, but back in the Windows 9x days, you could hold down shift while clicking restart, and it would perform a sort-of "soft" restart without going through a complete reboot cycle. What's going on here? The behavior you're seeing is the result of passing the EW_RESTART­WINDOWS flag to the old 16-bit Exit­Windows function. What happens is that the 16-bit Windows kernel shuts down, and then the 32-bit virtual memory manager shuts down, and the CPU is put back into real mode, and control returns to win.com with a special signal that means "Can you start protected mode Windows again for me?" The code in win.com prints the "Please wait while Windows restarts…" message, and then tries to get the system back into the same state that it was in back when win.com had been freshly-launched. ↫ Raymond Chen There's a whole lot more involved behind the curtains, of course, and if conditions aren't right, the system will still perform a full reboot cycle. Chen further notes that because WIN.COM was written in assembly, getting back to that "freshly-launched" state wasn't always easy to achieve. I only vaguely remember you could hold down shift and get a faster "reboot", but I don't remember ever really using it. I've been digging around in my memories since I saw this story yesterday, and I just can't think of a scenario where I would've realised in time that I could do this.

Xous is a microkernel operating system designed for medium embedded systems with clear separation of processes. Nearly everything is implemented in userspace, where message passing forms the basic communications primitive. ↫ Xous website It's written in Rust, and it's been around for a while - so much so it's sponsored by NLnet and the EU. The Xous Book provides a ton more details and information, with a strong focus on the kernel. You can run Xous in hosted mode on Linux, Windows, or macOS, inside the Renode emulator, or on the one supported hardware device, the Precursor. Obviously, the code's open and on GitHub (which they should really be moving to a European solution now that the Americans are threatening the EU with war over Greenland).

Have you noticed how it seems like how the "light mode" of your graphical user interface of choice is getting lighter over time? It turns out you're not crazy, and at least for macOS, light mode has indeed been getting lighter. You can clearly see that the brightness of the UI has been steadily increasing for the last 16 years. The upper line is the default mode/light mode, the lower line is dark mode. When I started using MacOS in 2012, I was running Snow Leopard, the windows had an average brightness of 71%. Since then they've steadily increased so that in MacOS Tahoe, they're at a full 100%. ↫ Will Richardson While this particular post only covers macOS, I wouldn't be surprised to discover similar findings in Windows, GNOME, and KDE. The benefit of using KDE is that it's at least relatively easy to switch colour schemes or themes, but changing colours in Windows is becoming a hidden feature, and GNOME doesn't support it out of the box at all, and let's not even get started about macOS. I think "light mode" should be "grey mode", and definitely lament the lack of supported, maintained "grey modes" in both KDE and GNOME. There's a reason that graphical user interfaces in the era of extensive science-based human-computer interaction research opted for soft, gentle greys (ooh, aah, mmm), and I'm convinced we need to bring it back. The glaring whites we use today are cold and clinical, and feel unpleasant to the point where I turn down the brightness of my monitor in a way that makes other colours feel too muted. Or perhaps I'm out of touch.

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.

VOA is a generic framework for verifying any kind of distribution artifacts (i.e. files) using arbitrary signature verification technologies. The voa CLI ⌨️ The voa project offers the voa(1) command line interface (CLI) which makes use of the voa(5) configuration file format for technology backends. It is recommended to read the respective man pages to get …

In 2024 the Sovereign Tech Fund (STF) started funding work on the ALPM project, which provides a Rust-based framework for Arch Linux Package Management. Refer to the project's FAQ and mission statement to learn more about the relation to the tooling currently in use on Arch Linux. The funding has now concluded, but over the time of 15 months allowed us to create various tools and integrations that we will highlight in the following sections. We have worked on six milestones with focus on various aspects of the package management ecosystem, ranging from formalizing, parsing and writing of …
