“NASA took a significant step Tuesday toward allowing humans on the moon to ‘live off the land,'” reports the Washington Post.
NASA awarded several contracts “to build landing pads, roads and habitats on the lunar surface, use nuclear power for energy, and even lay a high-voltage power line over half a mile…”

Instead of going to the moon and returning home, as was done during the Apollo era of the 1960s and early ’70s, NASA intends to build a sustainable presence focusing on the lunar South Pole, where there is water in the form of ice. The contracts awarded Tuesday are some of the first steps the agency is taking toward developing the technologies that would allow humans to live for extended periods of time on the moon and in deep space. Materials on the moon must be used to extract the necessities such as water, fuel and metal for construction, said Prasun Desai, NASA’s acting associate administrator for space technology. “We’re trying to start that technology development to make that a reality in the future,” he said.

The largest award, $34.7 million, went to billionaire Jeff Bezos’s Blue Origin space venture, which has been working on a project since 2021 called Blue Alchemist to build solar cells and transmission wire out of the moon’s regolith — rocks and dirt. In a blog post this year, Blue Origin said it developed a reactor that reaches temperatures of nearly 3,000 degrees and uses an electrical current to separate iron, silicon and aluminum from oxygen in the regolith. The testing, using a lunar regolith simulant, has created silicon pure enough to make solar cells to be used on the lunar surface, the company said. [NASA says it could also be used to make wires.] The oxygen could be used for humans to breathe. “To make long-term presence on the moon viable, we need abundant electrical power,” the company wrote in the post. “We can make power systems on the moon directly from materials that exist everywhere on the surface, without special substances brought from Earth.”
The award is another indication that Blue Origin is trying to position itself as a key player in helping NASA build a permanent presence on and around the moon as part of the Artemis program… The company said it is developing a solar-powered storage tank to keep propellants at 20 degrees Kelvin, or about minus-423 degrees Fahrenheit, so spacecraft can refuel in space instead of returning to Earth between missions.
Other winners cited in the article:

Zeno Power, which “intends to use nuclear energy to provide power on the moon,” received a $15 million contract (partnering with Blue Origin).
Astrobotic — which plans to launch a lander to the moon this year — got a $34.6 million contract “to build a power line that would transmit electricity from a lunar lander’s solar arrays to a rover. It ultimately intends to build a larger power source using solar arrays on the moon’s surface.”
Redwire won a $12.9 million contract “to help build roads and landing pads on the moon. It would use a microwave emitter to melt the regolith and transform treacherous rocky landscapes into smooth, solid surfaces, said Mike Gold, Redwire’s chief growth officer.”

The technologies — which include in-space 3D printing — “will expand industry capabilities for a sustained human presence on the Moon,” NASA said in a statement.

The U.S. space agency will contribute a total of $150 million, with each company contributing at least 10-25% of the total cost (based on their size). “Partnering with the commercial space industry lets us at NASA harness the strength of American innovation and ingenuity,” said NASA Administrator Bill Nelson. “The technologies that NASA is investing in today have the potential to be the foundation of future exploration.”

“Our partnerships with industry could be a cornerstone of humanity’s return to the Moon under Artemis,” said acting associate administrator Desai. “By creating new opportunities for streamlined awards, we hope to push crucial technologies over the finish line so they can be used in future missions.

“These innovative partnerships will help advance capabilities that will enable sustainable exploration on the Moon.”

After Red Hat’s decision to only share RHEL source code with subscribers, AlmaLinux asked their bug report submitters to “attempt to test and replicate the problem in CentOS Stream as well, so we can focus our energy on correcting it in the right place.”

Red Hat told Ars Technica they are “eager to collaborate” on their CentOS Stream distro, “even if we ultimately compete in a business sense. Differentiated competition is a sign of a healthy ecosystem.”

But Red Hat still managed to ruffled some feathers, reports ZDNet:
AlmaLinux Infrastructure Team Leader Jonathan Wright recently posted a CentOS Stream fix for CVE-2023-38403, a memory overflow problem in iperf3. Iperf3 is a popular open-source network performance test. This security hole is an important one, but not a huge problem.

Still, it’s better by far to fix it than let it linger and see it eventually used to crash a server. That’s what I and others felt anyway. But, then, a senior Red Hat software engineer replied, “Thanks for the contribution. At this time, we don’t plan to address this in RHEL, but we will keep it open for evaluation based on customer feedback.”

That went over like a lead balloon.
The GitLab conversation proceeded:

AlmaLinux: “Is customer demand really necessary to fix CVEs?”

Red Hat: “We commit to addressing Red Hat defined Critical and Important security issues. Security vulnerabilities with Low or Moderate severity will be addressed on demand when [a] customer or other business requirements exist to do so.”

AlmaLinux: “I can even understand that, but why reject the fix when the work is already done and just has to be merged?”
At this point, Mike McGrath, Red Hat’s VP of Core Platforms, AKA RHEL, stepped in. He explained, “We should probably create a ‘what to expect when you’re submitting’ doc. Getting the code written is only the first step in what Red Hat does with it. We’d have to make sure there aren’t regressions, QA, etc. … So thank you for the contribution, it looks like the Fedora side of it is going well, so it’ll end up in RHEL at some point.”

Things went downhill rapidly from there…

On Reddit, McGrath said, “I will admit that we did have a great opportunity for a good-faith gesture towards Alma here and fumbled.”
Finally, though the Red Hat Product Security team rated the CVE as “‘Important,’ the patch was merged.

Coincidentally, last month AlmaLinux announced that its move away from 1:1 compatibility with RHEL meant “we can now accept bug fixes outside of Red Hat’s release cycle.”

This Thursday AlmaLinux also reiterated that they’re “fully committed to delivering the best possible experience for the community, no matter where or what you run.” And in an apparent move to beef up compatibility testing, they announced they’d be bringing openQA to the RHEL ecosystem. (They describe openQA as a tool using virtual machines that “simplifies automated testing of the whole installation process of an operating system in a wide combination of software and hardware configurations.”)

“For years scientists have believed that when it comes to weight gain, all calories are created equal,” the Washington Post reported last month.

“But an intriguing new study, published in the journal Nature Communications, suggests that’s not true. The body appears to react differently to calories ingested from high-fiber whole foods vs. ultra-processed junk foods.”

The reason? Cheap processed foods are more quickly absorbed in your upper gastrointestinal tract, which means more calories for your body and fewer for your gut microbiome, which is located near the end of your digestive tract. But when we eat high-fiber foods, they aren’t absorbed as easily, so they make the full journey down your digestive tract to your large intestine, where the trillions of bacteria that make up your gut microbiome are waiting. By eating a fiber-rich diet, you are not just feeding yourself, but also your intestinal microbes, which, the new research shows, effectively reduces your calorie intake.

The study reveals that inside all of us, our gut microbes are in a tug of war with our bodies for calories, said Karen D. Corbin, an investigator at the AdventHealth Translational Research Institute of Metabolism and Diabetes in Orlando and the lead author of the study.

The closely-tracked study participants ate foods “like crispy puffed rice cereal, white bread, American cheese, ground beef, cheese puffs, vanilla wafers, cold cuts and other processed meats, and sugary snacks and fruit juices.” Then they switched to the “microbiome enhancer diet,” with foods like “oats, beans, lentils, chickpeas, brown rice, quinoa and other whole grains” (plus fruits, nuts and vegetables).

Despite getting “the same amount of calories and similar amounts of protein, fat and carbohydrates,” the Post reports that “On average, they lost 217 calories a day on the fiber-rich diet, about 116 more calories than they lost on the processed-food diet.”

Python’s Global Interpreter Lock “allows only one thread to hold the control of the Python interpreter,” according to the tutorial site Real Python. (They add, “it can be a performance bottleneck in CPU-bound and multi-threaded code.”)

Friday the Python Steering Council “announced its intent to accept PEP 703 (Making the Global Interpreter Lock Optional in CPython), with initial support possibly showing up in the 3.13 release,” reports LWN.net.

From the Steering Council’s announcement:

It’s clear that the overall sentiment is positive, both for the general idea and for PEP 703 specifically. The Steering Council is also largely positive on both. We intend to accept PEP 703, although we’re still working on the acceptance details…

Our base assumptions are:

– Long-term (probably 5+ years), the no-GIL build should be the only build. We do not want to create a permanent split between with-GIL and no-GIL builds (and extension modules).

– We want to be very careful with backward compatibility. We do not want another Python 3 situation, so any changes in third-party code needed to accommodate no-GIL builds should just work in with-GIL builds (although backward compatibility with older Python versions will still need to be addressed). This is not Python 4. We are still considering the requirements we want to place on ABI compatibility and other details for the two builds and the effect on backward compatibility.

– Before we commit to switching entirely to the no-GIL build, we need to see community support for it. We can’t just flip the default and expect the community to figure out what work they need to do to support it. We, the core devs, need to gain experience with the new build mode and all it entails. We will probably need to figure out new C APIs and Python APIs as we sort out thread safety in existing code. We also need to bring along the rest of the Python community as we gain those insights and make sure the changes we want to make, and the changes we want them to make, are palatable.

– We want to be able to change our mind if it turns out, any time before we make no-GIL the default, that it’s just going to be too disruptive for too little gain. Such a decision could mean rolling back all of the work, so until we’re certain we want to make no-GIL the default, code specific to no-GIL should be somewhat identifiable.
The current plan is to “add the no-GIL build as an experimental build mode, presumably in 3.13… [A]fter we have confidence that there is enough community support to make production use of no-GIL viable, we make the no-GIL build supported but not the default (yet), and set a target date/Python version for making it the default… We expect this to take at least a year or two, possibly more.”

“Long-term, we want no-GIL to be the default, and to remove any vestiges of the GIL (without unnecessarily breaking backward compatibility)… We think it may take as much as five years to get to this stage.”

Thursday Bill Gates launched a new podcast called “Unconfuse Me.” (“What do you do when you can’t solve a problem? I like to talk to smart people who can help me understand the subject better…”)
Join me on my learning journey as I talk to brilliant guests about Alzheimer’s, artificial intelligence, the future of education, plant-based meat, the evolution of language, marijuana, and more.
The first words of the first episode are a clip of Seth Rogen saying “Edibles? I don’t mess with that. Snoop Dogg doesn’t eat edibles. Like, that’s how wild the variation on edibles is, and I do not recommend this.”
Then Bill Gates’ voice says “I love learning, even if a topic’s complex, I like to see if I can figure it out…” People reports that the 67-year-old Microsoft co-founder and former CEO also spoke to Rogen and his wife Lauren Miller about the future of Alzheimer’s research:

With studies showing that “40% of cases” are preventable, according to Rogen, the “five brain healthy habits” in their framework are important: sleep, exercise, nutrition, mental fitness and emotional well-being.
He even confessed that his being a celebrity encourages people to better care for themselves. “I taught this coursework of brain health, and we’ve also had a neurologist teach the coursework, and we scientifically proved that people retain information better from celebrities than doctors, which is it’s a heavy burden,” he joked, adding that this information “was published…”

Miller also shared that she goes to a neurologist and the pair are both “open” with their doctors about their habits, and “no one” in the medical world has told them that smoking weed is bad for their brain health. They even believe its benefits of boosting hunger and relieving stress might be good for preventing Alzheimer’s. “It’s not federally legal, so there isn’t money to fund research,” Miller said.

Gates later concluded the podcast with his own funny anecdote, laughing about his first time he ever smoked weed — back when it was a “rebellious” thing to do. “In school out of the, say 105 people in my class I think, there were three or four who didn’t smoke,” he said. “Because it was kind of a, ‘Hey, I’m an adult! Hey I can break the rules!’ But I will say, sometimes it’s like, I guess I’m doing this to be cool. It wasn’t so much smoking for pot’s sake.”
