A medical report published earlier this week says a boy in the U.K. developed erythema ab igne, or "toasted skin syndrome," after resting a laptop on his abdomen for up to eight hours a day, often while it was charging. "The marks were described as being in a patch about 15 centimeters (six inches) wide, made of flat, reddish-brown 'interlacing lines forming irregular circles and a lace-like morphology,'" reports Ars Technica. From the report: Based on the appearance, the doctors started reconsidering some sort of bruising and started asking him more questions. This is when he mentioned that he was homeschooled and used a laptop for his schoolwork. He said he typically did his work by resting his laptop on his abdomen while he worked, sometimes for up to eight hours a day, and often while the laptop was charging. Then they understood what it was.

The doctors diagnosed the boy with erythema ab igne (EAI), which translates from Latin as "redness from fire" and is also sometimes called "toasted skin syndrome." This is a skin condition caused by repeated, prolonged exposure to low-grade heat -- heat not hot enough to cause actual burns. It's most often seen in adults, and common causes include using heating pads or hot water bottles for chronic pain or sitting too close to space heaters. Some people also develop it from certain occupational hazards, like glassblowing and metal work. EAI produces a lace-like rash, just like the boy's.

It's unclear how EAI develops exactly. But researchers hypothesize that chronic heat exposure leads to damage to superficial blood vessels and the release of red blood cells, forming the tell-tale red reticulated pattern. While the boy's condition looked ominous, the good news is that EAI is generally benign and reversible -- once you remove the heat source. For severe or long-term conditions, some pigmentation and scarring can remain. But the boy's parents checked back in over several months, reporting that the rash faded and then completely resolved. Hopefully, he also got some sort of laptop stand.

Phoronix reports: AMD is building out what they are describing as an "elite" team of developers for driving Rust code "deep into the GPU stack" from firmware to drivers, shader compilers, and other GPU software in Rust. AMD Senior Fellow Harsh Meno posted this week to LinkedIn about this new effort...

And note this AMD job posting that's active for hiring a software development engineer to work on Rust code...

"We are building next-generation systems software for AMD GPUs with Rust as a core technical direction. The work spans compilers, runtimes, low-level GPU software, firmware, developer tooling, and methods for improving the safety and correctness of complex hardware-software systems.

"Rust is not incidental to this role. You will help establish how Rust is used in performance-sensitive and high-trust parts of the GPU stack, including the compiler and tooling support, system interfaces, engineering practices, and validation methods required for production deployment. You will have the opportunity to influence both near-term implementations and the longer-term architecture for using Rust across current and future AMD platforms."
"AMD also isn't alone," the article points out, "as NVIDIA has also been pursuing similar Rust-based initiatives for their GPU software too, including the development of the Nova Linux kernel driver written in Rust."

Longtime Slashdot reader Microsplat: CERN plans to have all 2,200+ industrial computers and embedded systems in its accelerator-control infrastructure running Debian 13 by the end of 2026. These are systems used for accelerator control, laboratory equipment and other operational functions ... They also generate and interact with a hefty amount of data, although this Linux.com article refers more broadly to CERN's computing infrastructure. It's unclear whether the Debian migration covers all server infrastructure or what scientific-research-based systems are included. Our shops have done much the same in recent years, mostly due to CentOS and CFEngine getting the can. Phoronix adds some additional context in its article: CERN was a longtime RHEL/CentOS shop, previously co-maintained the Scientific Linux RHEL derivative, moved to CentOS in 2015, and later considered CentOS Stream. CERN says Red Hat's adoption of the "-march=x86-64-v2" compiler flag by default, which it viewed as "forced obsolescence" of older hardware, was the "straw that broke the camel's back."

Starting today, unsolicited telemarking calls are banned in France unless consumers explicitly consent to them. Companies that violate the law can face fines of up to 375,000 euros per call, though existing customers can still be contacted with related offers. Le Monde reports: The government says the law is a response to years of consumer complaints. Authorities estimate that about three-quarters of people in France receive at least one unsolicited sales call every week, and many receive more. In 2024, 11 consumer organizations issued a joint call for a ban, denouncing "relentless harassment of consumers through countless unwanted telemarketing calls to both landlines and mobile phones -- an intrusion that has become a regular part of their daily lives."

Now, "businesses are prohibited from contacting consumers without their prior consent," said Alice Vilcot, chief of staff at the Directorate-General for Competition, Consumer Affairs and Prevention of Fraud. "That consent can be withdrawn at any time." [...] Previously in France, people who wanted to avoid marketing calls had to register their number with a government-run service, but consumer groups said some call centers ignored the list. Vilcot noted that an Ireland-based company was fined 6 million euros ($6.9 million) last year for violating France's previous telemarketing rules by calling people on the no-call list.

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.
