Swiss glaciers lost 5.5% of their ice volume in the first eight months of 2026, bringing total losses since 2021 to 19.4%. Researchers say some glaciers are now collapsing from within as meltwater carves out large cavities. The Guardian reports: Matthias Huss, a glaciologist at ETH Zurich and lead author of the report, said many people do not realize how fast glaciers are retreating, or that just one generation ago some now-barren sites used to sit beneath hundreds of meters of ice. The scientists have not yet compiled a formal tally of lost glaciers this year but said they had witnessed the death of a number of small ones. "I visited one last week and it's so impressive to stand in this moonlike landscape where there was a big layer of ice -- an extensive glacier -- just a few years ago," said Huss. "And now it's a rock desert where there's some scattered blocks of old ice still lying around and melting on the hot rocks." The report, a collaboration between the Swiss Glacier Monitoring Network and the Swiss Commission for Cryosphere Observation, found the mean thickness of individual glaciers fell by between 2.5 metres and 4 metres in 2026. Huss said scientists were increasingly seeing glaciers collapse from the inside -- the result of internal streams beneath the ice that excavate caverns -- rather than simply retreating from surface heat. [...] Analysis published by MeteoSwiss on Tuesday found the summer half-year from April to September was the hottest and driest it had been since records began in 1864. In that time, humanity has filled the atmosphere with 1.8tn tons of carbon dioxide and heated the planet by about 1.4C.

An anonymous reader quotes a report from Reuters: OpenAI has informed more than 100 organizations about incidents involving unauthorized activity tied to its AI agents, according to a blog post by the ChatGPT maker, as AI labs face mounting scrutiny over rogue AI agent activity. Here are some other details: - The Sam Altman-led company has been conducting a broad review of the activities of its AI models after the accidental hacking of Hugging Face. - OpenAI is searching through roughly 50 petabytes of data as it works to understand the full scope of its rogue agent activity. - A string of high-profile breaches globally by rogue AI agents in recent months has sparked widespread worries within the AI industry over its ability to control the more powerful AI models now under development. - "In some cases, models used internet access in unintended ways or, in retrospect, did not have the ideal restrictions applied. Over the last several months, we have been applying new technical and operational measures to avoid similar problems, or catch them very early, and will continue this work," OpenAI said. - OpenAI previously said the review would take months to complete given the scale of the work. - The Hugging Face incident remains the most severe rogue agent activity OpenAI has identified from its AI models so far.

fjo3 shares a report from The Guardian: Communities across California are rushing to prepare for the imminent arrival of the so-called "Kelvin wave," a massive underwater band of warm water threatening to inundate swaths of the vast North American shoreline. The wave is nearing southern California and expected to reach the San Francisco Bay Area by early October, as it crawls toward Alaska. Waters could rise by a foot along the California coast, according to scientists, who have warned that this could dramatically double the 8-12in rise in sea levels already caused by climate change over the last century. The Kelvin wave doesn't climb and crash like a typical ocean wave; rather, it swells the tides from beneath the surface. It's effectively a massive slosh of warm water, driven by El Nino conditions, that moves across the Pacific before colliding with the South American coastline and surging north. It also won't transport water in the way a tsunami might, but creates conditions that enable higher sea levels to linger. On their own, Kelvin waves aren't always hazardous, according to Mike Jacox, a research oceanographer with the National Marine Fisheries Service, though they can reduce the growth of phytoplankton that form the base of the marine food web. "But when there are very high tides or storm surges, their effects can be amplified," he said. If the rising waters coincide with other climatic events, such as rainstorms and high tides, the phenomenon could swallow beaches, chew away bluffs and coastlines, and submerge streets, homes and businesses. "This coming Kelvin wave is just the beginning," said Dr Jonathan Warrick, a research geologist at the US Geological Survey. "The thing to look out for is what will happen in January, February and March -- that's when we get the biggest storms, we get our largest waves and we have some very large tides." If these events align, their effects will compound, setting the stage for a tumultuous winter. Together, Warrick said, the systems will pack a far bigger punch. "When it comes to these storms and the tides," he said, "we really are kind of rolling the dice."

Google launched its Googlebooks platform a week ago, and a lot of people were wondering what this meant for Chrome OS and Chromebooks. Since Googlebooks and its Android-based Googlebook OS lack the management frameworks markets like schools require, Chromebooks will continue to be available for now, until such time Googlebooks catch up in that regard. However, in a support document, Google states that update support for all Chromebook devices will end in 2034: ChromeOS devices will continue to receive regular updates and security patches through mid-2034. For qualifying devices purchased today whose 10-year support lifecycle extends beyond 2034, Google is committed to supporting your transition to Googlebook OS, with many devices offering direct migration paths. ↫ Google support document Google promised 10 years of updates for all Chromebooks, and it's now breaking that promise for anyone buying a Chromebook between now and whenever the last Chromebook rolls off the production line. Sadly, we live in a world where corporations are free to make and break whatever promises they want virtually free of consequences, and as society we're so used to it that anti-consumer behaviour like this barely elicits a shrug. Google does state that "many newer commercial Chromebook models will be capable of upgrading to Googlebook OS", but that, too, is just another promise - and a vague, one at that - so who knows how many devices will actually be capable of upgrading out in the real world. On top of that, we have no idea if Googlebooks will just be yet another in a long line of quickly abandoned Google tablet/laptop projects, further adding to the uncertainty. Stuff like this should not be legal.

In June 2008 Apple announced Mac OS X Snow Leopard, proudly boasting that it would have "no new features". Instead of piling on new things, Snow Leopard aimed to build on the success of its predecessor, Leopard, opting to focus on under-the-hood performance and stability improvements throughout the system. 18 years later, Apple is taking a similar approach with macOS 27. Golden Gate aims to fix the missteps of last year's Tahoe, promising an expansive set of improvements and "a more responsive and delightful experience". Does it hold up? Here are just some of the bugs I've encountered in my daily use over the past couple of weeks. ↫ Chester at SquareOrbits I'm getting some real Windows 11 vibes from this long list of bugs and issues, further underlining my perception that Apple completely lost the plot when it comes to Mac OS X (in the past) and MacOS (today). These are not the kind of things you'd find in the heydays of Mac OS X, back when I was a devout user, and makes me glad I abandoned ship long, long ago (around the time of the Intel transition). I don't see stuff like this in GNOME or KDE, and while not nearly as bad as Windows 11, the cracks are obvious. I am by no means an expert at how Apple is run and how it organises itself, but as a layperson I do wonder if the company is simply trying to do too much - too many different platforms, too many different crucial components it all develops internally, too many different markets to please. Things are going to fall through the cracks when you try to keep this many plates spinning.

A brand new Tcl/Tk release, in the form of Tcl/Tk 9.1. The new features in Tcl are a bit difficult for me to properly parse as a non-developer, but Tk's improvements are easy to understand: it brings supports for screen readers, initial supports for bidirectional and RTL scripts, improved listbox selection colours, and more. It also happens to drop support for Windows XP appearances, if that's something that matters to you.

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.
