We all know Linux is written in C. What you may not know is that it’s written in a long-outdated C dialect: The 1989 version of the C language standard, C89. This is also known as ANSI X3.159‑1989, or ANSI C. Linus Torvalds has decided that enough is enough and will move Linux’s official C to 2011’s C11 standard.

The Linux kernel’s foundation is the ancient C89 standard of C. Now, Torvalds has decided to upgrade to 2011’s more modern C11 standard.

Interfacing technology and electronics with the real world is often fairly tricky. Complexity and edge cases work their way in to every corner of a project like this; just ask anyone who has ever tried to operate a rover on Mars, make a hydroponics garden, or build almost any robotics project. Even those of us who simply own a consumer-grade printer are flummoxed by the ways in which they can fail when manipulating single sheets of paper. This robotic lawnmower is no exception, driving its creator [TK] to extremes to get it to mow his lawn.

[TK] actually had a platform for his autonomous mower ready to go thanks to a previous build using this solar-powered robot to explore the Australian outback. Adding another motor to handle the grass trimming seemed simple at first and he set about wiring it all up and interfacing it to the robot. After the first iteration he found the robot was moving too fast to effectively cut the grass, so he added a more powerful cutting motor and a gearbox to help the mower crawl more slowly over the lawn. Disaster struck when his 3D printed mount for the steel cutting blades shattered, but with [TK] uninjured he pushed on with more improvements.

Brain organization differs between boys and girls with autism, according to a new study from the Stanford University School of Medicine.

The differences, identified by analyzing hundreds of brain scans with artificial intelligence techniques, were unique to autism and not found in typically developing boys and girls. The research helps explain why autism symptoms differ between the sexes and may pave the way for better diagnostics for girls, according to the scientists.

Autism is a developmental disorder with a spectrum of severity. Affected children have social and communication deficits, show restricted interests and display repetitive behaviors. The original description of autism, published in 1943 by Leo Kanner, MD, was biased toward male patients. The disorder is diagnosed in four times as many boys as girls, and most autism research has focused on males.

Engineers build a lower-energy chip that can prevent hackers from extracting hidden information from a smart device.

A heart attack patient, recently discharged from the hospital, is using a smartwatch to help monitor his electrocardiogram signals. The smartwatch may seem secure, but the neural network processing that health information is using private data that could still be stolen by a malicious agent through a side-channel attack.

A side-channel attack seeks to gather secret information by indirectly exploiting a system or its hardware. In one type of side-channel attack, a savvy hacker could monitor fluctuations in the device’s power consumption while the neural network is operating to extract protected information that “leaks” out of the device.

Aluminum is a highly reactive metal that can strip oxygen from water molecules to generate hydrogen gas. Now, researchers at UC Santa Cruz have developed a new cost-effective and effective way to use aluminum’s reactivity to generate clean hydrogen fuel.

In a new study, a team of researchers shows that an easily produced composite of gallium and aluminum creates aluminum nanoparticles that react rapidly with water at room temperature to yield large amounts of hydrogen. According to researchers, the gallium was easily recovered for reuse after the reaction, which yields 90% of the hydrogen that could theoretically be produced from the reaction of all the aluminum in the composite.

Easy aluminum nanoparticles split water and generate hydrogen gas rapidly under ambient conditions.

Mark Zuckerberg may still be explaining exactly what the metaverse is, but the Meta CEO just showed off another technology he says will be crucial to the company’s vision of creating immersive environments. Meta’s AI researchers are working on a voice-powered bot that allows users to change their virtual surroundings with voice commands.

Zuckerberg demoed an early version of the concept, called Builder Bot, at a virtual event detailing the company’s latest AI research.

“It enables you to describe a world and then it will generate aspects of that world for you,” Zuckerberg said. In his demo, he and another Meta employee used voice commands to create a very basic beach scene with a picnic table, clouds, and, yes, Zuckerberg’s signature hydrofoil. They also added some sound effects of seagulls and ocean waves.

Bacteria are the stuff of nightmares but we can take solace in the fact that they tend to be quite small, in fact, invisible to the naked eye.

Not anymore! Scientists have discovered a bacterium that is bigger than a fruit fly, according to a report by Science published on Wednesday.

The researchers also report being amazed by the bacterium’s complexity.

In Rogozin’s series of tweets, he claimed the sanctions could have severe consequences for the ISS and “destroy” international co-operation related to the ISS.

Another of his tweets said: “There is also the option of dropping a 500-ton structure to India and China. Do you want to threaten them with such a prospect? The ISS does not fly over Russia, so all the risks are yours. Are you ready for them?”

Musk appeared to confirm that SpaceX would get involved, should the ISS fall out of orbit. A Twitter user asked if that’s what the tech mogul really meant, to which Musk simply replied: “Yes.”
