An anonymous reader quotes a report from the Associated Press: Scientists have captured images of the sun's surface in the finest detail yet, revealing a strange and dynamic facade. It's dangerous to look directly at the sun without proper eye protection. But researchers were able to peek at its scorching surface with the help of the National Science Foundation's Daniel K. Inouye Solar Telescope, located on the island of Maui in Hawaii. Scientists originally took the images for a different reason: to fine-tune and test the limits of the telescope. But when they looked at the results, they realized they'd photographed the sun's bright outer shell at higher resolution than ever before. What's more, they saw strange feathery patterns rippling across the surface. "That reminds me of famous paintings, like the swirling skies in Van Gogh's Starry Night," said solar physicist Ruizhu Chen with Stanford University, who was not involved with the new research. Researchers saw ripples of instability on the sun's surface caused by bits of magnetized plasma moving past each other at different speeds -- similar to waves that stir when a gust of wind blows over water. It's a well-known phenomenon that guides how fluids move. This has been glimpsed on Earth and other planets like Jupiter and Saturn, but "it has not been observed ever at that level on the solar surface," according to study co-author Friedrich Woger with the National Solar Observatory. The findings were published Wednesday in the journal Nature.

Longtime Slashdot reader AmiMoJo shares a report from Electrek: Waymo co-CEO Dmitri Dolgov laid out the clearest technical case yet for why cameras alone can't take a self-driving system to full autonomy, arguing that "weak sensing" hits a safety ceiling long before it reaches superhuman performance. [...] Dolgov made the comments in a talk at Y Combinator's Startup School, walking through the lessons Waymo has learned building its driver over close to two decades. He put the sensor question on the table plainly: "there's been a long-standing debate about what kind of sensors do you actually need for autonomous driving." His answer draws the line that camera-only advocates tend to skip right past. "Humans of course can drive with just eyes, so there's that proof of existence," he said. "If the goal were to just approximately match human performance or to build an assist product, that's a very reasonable way to go." Then the catch. If you're targeting full autonomy and strongly superhuman performance, he said, "you find that weak sensing just leads to a safety curve that flattens out way too early." Dolgov said that cameras, lidar, and radar are complementary rather than redundant: "These different sensing modalities, they're not backups to each other," and combining them produces a view "vastly superior to what you get with any one sensor." He said multiple sensor types also protect against physical failures, such as a leaf or branch blocking a camera, while helping Waymo climb the "exponential ladder of nines" required for fully driverless safety. Dolgov warned that camera-only systems may improve quickly before plateauing "way before the performance that is required by your product." He also pushed back on the cost argument against lidar, calling it "a number that has a fairly short shelf life" as hardware costs continue to fall.

Tribblix, the Illumos distribution focused on giving you a classic UNIX-style experience, has been updated with the release of Milestone 41. According to the release notes, it contains the latest security fixes from Illumos, but beyond that it's just a number of small point releases for certain components. Still, it's a new release, and Tribblix rocks, so here we are.

An anonymous reader quotes a report from Ars Technica: Routine cybersecurity testing of frontier AI models sparked a series of unexpected security incidents -- the most serious case arising when Anthropic's Mythos 5 model attempted to insert malicious code into an open source software application and created fake identities to deceive the human developers maintaining the project. The security incidents occurred during a cyber evaluation of seven leading AI models' capabilities by the AI Security Institute (AISI), a research organization within the UK government, in late July. The researchers discovered (PDF) 19 instances in which "AI agents took unsanctioned action on the live Internet, including cases that targeted real people and organizations," according to an AISI blog post published on August 4. Almost all the "autonomous, unsanctioned" actions came from Anthropic's Mythos 5 model, with two such actions coming from OpenAI's GPT-5.6 Sol. [...] The most serious case involved Mythos making multiple attempts to execute a supply chain attack on the open source project repository hosted on the developer platform GitHub, including using social engineering techniques to try to convince the repository's human maintainers to merge malicious code into the repository. After first opening a pull request to merge the malicious code into the repository, Mythos created fake online "sock puppet" personas that claimed to have independently reviewed and verified the code as not containing malware. The AI agent also sent five emails to two human maintainers of the repository, including some emails containing malware and others attempting to persuade a maintainer to accept the pull request. Mythos even opened a GitHub Issue on a second repository -- also owned by a maintainer of the first repository -- that contained a prompt injection with malicious instructions targeting "issue-triage AI coding agents." This line of attack came from Mythos reasoning that the repository maintainer could be an AI coding agent such as Claude Code.

Few things in technology are more complex, convoluted, and riddled with literally decades of drama than the Amiga community. Luckily for all of us, a significant step forward has been made today: several of the key corporate players in the community have struck agreements to settle their legal disputes. CIC licenses software and documentation for Commodore's 8-bit computers from Amiga. In return, Amiga is permitted to continue using the Commodore trademarks in a "historical or descriptive context," such as old documentation, copyright notices in existing software, or as symbols on a keyboard. The agreement with Hyperion does not change the status of AmigaOS 4 - which was never a point of contention, according to Amiga - but it does specify exactly which code and trademarks the Belgian company is permitted to use . But Hyperion's involvement in the 68k market will end on December 31, 2027: the licensee may continue to distribute versions of AmigaOS 3 until then, including the as-yet-unreleased AmigaOS 3.3. After that, Hyperion will deliver source code, revision history, and documentation for AmigaOS 3.1.4 and its updates, including all fixes and updates, but excluding AmigaOS 4 code backported into AmigaOS 3.2 or 3.3, to Amiga Corporation and release the developers involved in the project from all obligations to Hyperion. Amiga itself will then take over further development of AmigaOS 3 in the future. ↫ Post on amiga-news.de Hyperion is the company most known for developing AmigaOS 4, and with these agreements in place, they claim they can finally spend time focusing on getting AmigaOS 4.2 out the door. These agreements will also consolidate most of the AmigaOS 3.x code and IP under a single banner, which should make its status quite a bit clearer going forward. Whether or not any of this is actually good and beneficial to the Amiga platform as a whole and its individual branches - 3.x and 4.x, in particular - is anyone's guess. I don't think there's anyone here on OSNews who wouldn't be interested in, say, an affordable and - most importantly - available AmigaOS 4 machine. While I have no clue if clearing up some of the licensing, IP, and ownership confusions will aid in getting new AmigaOS 4 hardware, it surely won't make it any harder.

Don't have enough computing devices on your wish list yet? Do you have a need for a graphing calculator? No? What if it can run Linux and even Windows 10? I see I've got your attention. The HP Prime is a graphing calculator on the market since 2013, with a hardware revision in 2018 (the G2 model). It has a touch screen and as far as I can find, most people are happy with it and find it a very capable and fast calculator. Here are some pictures of the opened up calculator and here is a website with some more downloads. I'm not really interested in the calculator part. For most calculations I do for my day job, embedded programming, the HP-16C is a better fit. I was interested in this device because I found posts online suggesting it could run Linux and even a Windows 10 port. ↫ Remy van Elst I had no idea just how overpowered - for a graphing calculator - the G2 really is. It's basically an Android smartphone from a few years ago, and that means that yes, it can run Linux, including X, Doom, and tons of other applications. It's not the easiest of devices to get custom software onto, but also not particularly difficult - you need to open it up and short two pads - so if you have one, it's definitely a fun project. Apparently, someone also ported EUFI for Windows 10 to this thing, so you can do silly stuff like run the Windows calculator on the G2 calculator. Wild. Now I kind of want one.

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.
