Linux 6.1 (released last month) included what Linus Torvalds described as “initial Rust scaffolding,” remembers this update from SD Times But now, “work has already been done since the 6.1 release to add more infrastructure for Rust in the kernel, though still none of the code interacts with any C code.”

And there’s still no actual Rust code in Linux:

“You need to get all those things that can make sure that Rust can compile, and you can do the debugging and all these things,” explained Joel Marcey, director of advocacy and operations for the Rust Foundation, “and make sure that the memory safety is there and all that sort of stuff. And that has to happen first before you can actually write any real code in Rust for the Linux kernel itself.”

Marcey explained that Linux is going to be doing this inclusion very piecemeal, with lots of little integrations here and there over time so they can see how it is working. “I would imagine that over the next year, you’re going to see more small incremental changes to the kernel with Rust, but as people are seeing that it’s actually kind of working out, you’ll be able to maybe, for example, write Linux drivers or whatever with Rust,” said Marcey….

According to Bec Rumbul, executive director of the Rust Foundation, Rust being added to the kernel is an “enormous vote of confidence in the Rust programming language.” She explained that in the past other languages have been planned to make it into the kernel and ended up not getting put in. “I think having someone with the kind of intellectual gravity of Linus Torvalds saying ‘No, it’s going in there,’ that kind of says an awful lot about how reliable Rust already is and how much potential there is for the future as well,” she said.

Rumbul believes that there will be an increased interest in the language, which is still relatively new (It first made its debut in 2010) compared to some of the other languages out there to choose from. “I suspect that because Rust is now in the kernel, and it’s just being talked about much … more widely, that it will seem like an attractive prospect to a lot of people that are looking to develop their skills and their knowledge,” she said. Rumbul hopes people will also be inspired to participate in the language as contributors and maintainers, because those are some of the less popular roles within open source, but are extremely critical to the health of a language, she explained.
The Rust Foundation also launched a new security team in September to ensure best practices (including a dedicated security engineer). Their first initiative will be a security audit and threat modeling exercises.

“We want to basically shore up,” Rust operations director Marcey tells SD Times, “to ensure that Rust itself is actually as secure as we always say it is.”

In this year’s Stack Overflow Developer Survey, 86.73% of developers said they love Rust.

Huawei “is giving up on Europe,” writes Politico, saying the Chinese telecommunications company is “retrenching its European operations and putting its ambitions for global leadership on ice.”

“The reasons for doing this have little to do with the company’s commercial potential — Huawei is still able to offer cutting-edge technology at lower costs than its competitors — and everything to do with politics, according to interviews with more than 20 current and former staff and strategic advisers to the company.”

Pressed by the United States and increasingly shunned on a Continent it once considered its most strategic overseas market, Huawei is pivoting back toward the Chinese market, focusing its remaining European attention on the few countries — Germany and Spain, but also Hungary — still willing to play host to a company widely viewed in the West as a security risk.

“It’s no longer a company floating on globalization,” said one Huawei official. “It’s a company saving its ass on the domestic market….”

Huawei’s predicament was summed up by the company’s founder Ren Zhengfei in a speech to executives at the company’s Shenzhen headquarters in July. He laid out the trifecta of challenges the company has faced over the last three years: hostility from Washington; disruptions from the coronavirus pandemic; and Russia’s invasion of Ukraine, which upended global supply chains and heightened European concerns about over-dependence on countries like China. “The environment we faced in 2019 was different from the one we face today,” Ren said in his speech, which wasn’t made public but was seen by POLITICO. “Don’t assume that we will have a brighter future.”

“We previously had an ideal for globalization striving to serve all humanity,” he added. “What is our ideal today? Survival….!”

The company is also retrenching elsewhere, according to Ren. “We will give up markets in some countries,” the firm’s founder said in his speech this summer. “For example, we will give up markets in the Five Eyes countries and India.” The “Five Eyes” refers to an intelligence-sharing arrangement between the U.S., U.K., Canada, Australia and New Zealand. All five countries have banned or are in the process of banning Huawei and other Chinese companies from their critical infrastructure because of security concerns.

“The powerful Webb telescope doesn’t need to take pretty pictures to revolutionize our grasp of the cosmos,” notes Mashable.

It’s “a game changer,” says one of the researchers. They’re part of what the Webb telescope’s web site calls “an international team numbering in the hundreds” that “independently analysed data from four of the Webb telescope’s finely calibrated instrument modes.” And their ground-breaking first results? The James Webb Space Telescope “just scored another first: a molecular and chemical portrait of a distant world’s skies.”

The European Space Agency’s page for the telescope explains why revealing a “broad swath of the infrared spectrum and a panoply of chemical fingerprints” is so groundbreaking:

While Webb and other space telescopes, including the NASA/ESA Hubble Space Telescope, have previously revealed isolated ingredients of this heated planet’s atmosphere, the new readings provide a full menu of atoms, molecules, and even signs of active chemistry and clouds…. The telescope’s array of highly sensitive instruments was trained on the atmosphere of WASP-39 b, a “hot Saturn” (a planet about as massive as Saturn but in an orbit tighter than Mercury) orbiting a star some 700 light-years away…. Webb’s exquisitely sensitive instruments have provided a profile of WASP-39 b’s atmospheric constituents and identified a plethora of contents, including water, sulphur dioxide, carbon monoxide, sodium and potassium.

Earlier Mashable explained that the researchers “wait for planets to travel in front of their bright stars. This starlight passes through the exoplanet’s atmosphere, then through space, and ultimately into instruments called spectrographs aboard Webb… essentially hi-tech prisms, which separate the light into a rainbow of colors. Here’s the big trick: Certain molecules, like water, in the atmosphere absorb specific types, or colors, of light.”

From the Webb Telescope’s site:

The findings bode well for the capability of Webb’s instruments to conduct the broad range of investigations of exoplanets — planets around other stars — hoped for by the science community. That includes probing the atmospheres of smaller, rocky planets like those in the TRAPPIST-1 system…. Among the unprecedented revelations is the first detection in an exoplanet atmosphere of sulphur dioxide, a molecule produced from chemical reactions triggered by high-energy light from the planet’s parent star…. “This is the first time we have seen concrete evidence of photochemistry — chemical reactions initiated by energetic stellar light — on exoplanets,” said Shang-Min Tsai, a researcher at the University of Oxford in the United Kingdom and lead author of the paper explaining the origin of sulphur dioxide in WASP-39 b’s atmosphere. “I see this as a really promising outlook for advancing our understanding of exoplanet atmospheres….”

This led to another first: scientists applying computer models of photochemistry to data that require such physics to be fully explained. The resulting improvements in modelling will help build the technological know-how needed to interpret potential signs of habitability in the future…. The planet’s proximity to its host star — eight times closer than Mercury is to our Sun — also makes it a laboratory for studying the effects of radiation from host stars on exoplanets. Better knowledge of the star-planet connection should bring a deeper understanding of how these processes affect the diversity of planets observed in the galaxy.

Other atmospheric constituents detected by the Webb telescope include sodium (Na), potassium (K), and water vapour (H2O), confirming previous space- and ground-based telescope observations as well as finding additional fingerprints of water, at these longer wavelengths, that haven’t been seen before. Webb also saw carbon dioxide (CO2) at higher resolution, providing twice as much data as reported from its previous observations….

By precisely revealing the details of an exoplanet atmosphere, the Webb telescope’s instruments performed well beyond scientists’ expectations — and promise a new phase of exploration of the broad variety of exoplanets in the galaxy. “We are going to be able to see the big picture of exoplanet atmospheres,” said Laura Flagg, a researcher at Cornell University and a member of the international team. “It is incredibly exciting to know that everything is going to be rewritten. That is one of the best parts of being a scientist.”

Webb is an international partnership between NASA, ESA and the Canadian Space Agency.

From the BBC:

“Individuals associated with the U.S. military” are linked to an online propaganda campaign, Meta’s latest adversarial-threat report says….

On Facebook, 39 accounts, 16 pages, and two groups were removed, as well as 26 accounts on Instagram, for violating the platforms’ policy against “coordinated inauthentic behaviour”. “This network originated in the United States,” Meta wrote. It focused on countries including Afghanistan, Algeria, Iran, Iraq, Kazakhstan, Kyrgyzstan, Russia, Somalia, Syria, Tajikistan, Uzbekistan and Yemen — and mirrored tactics commonly used in propaganda campaigns against the West…

Some of those supporting the U.S. had posed as independent media outlets and some had tried to pass off content from legitimate outlets, such as BBC News Russian, as their own. The operation ran across many internet services, including Twitter, YouTube, Telegram, VKontakte and Odnoklassniki, according to Meta. “Although the people behind this operation attempted to conceal their identities and coordination, our investigation found links to individuals associated with the US military,” its report says.
The article adds that experts believe the campaign “was largely ineffective.”
