Long-time Slashdot reader theodp writes: “42 states to go!” exclaimed Code.org to its 1+ million Twitter followers as it celebrated victorious efforts to pass legislation making North Carolina the 8th state to pass a high school computer science graduation requirement, bringing the tech-backed nonprofit a step closer to its goal of making CS a requirement for a HS diploma in all 50 states. But as states make good on pledges made to tech CEOs to make their schoolchildren CS savvy, Education Week cautions that K-12 CS has a big certified teacher shortage problem.
From the article:
When trying to ensure all students get access to the knowledge they need for college and careers, sometimes policy can get ahead of teacher capacity. Computer science is a case in point. As of 2022, every state in the nation has passed at least one law or policy intended to promote K-12 computer science education, and 53 percent of high schools offered basic computer science courses that year, according to the nonprofit advocacy group Code.org.” “‘There’s big money behind making [course offerings] go up higher and faster,’ thanks to federal and state grants as well as private foundations, said Paul Bruno, an assistant professor of education policy, organization, and leadership at the University of Illinois Urbana-Champaign. “But then that raises the question, well, who are we getting to teach these courses…?”
Bruno’s work in states such as California and North Carolina suggests that few of those new computer science classes are staffed with teachers who are certified in that subject.”
Given how much time we spend interacting with coworkers either in person or virtually, various relationship and dynamics are bound to emerge. Sometimes colleagues can become genuine friends; other times, those relationships can turn out to be toxic or manipulative.
Long-time Slashdot reader mejustme writes: The NIST elliptic curves that power much of modern cryptography were generated in the late ’90s by hashing seeds provided by the NSA. Rumor has it that they are in turn hashes of English sentences, but the person who picked them, Dr. Jerry Solinas, passed away in early 2023 leaving behind a cryptographic mystery.”
That’s from the blog of Filippo Valsorda, who was in charge of cryptography and security on the Go team at Google until 2022, (and was on the Cryptography team at Cloudflare until 2017). But more importantly, he adds that “I’m announcing a $12,288 bounty for cracking these five hashes, tripled to $36,864 if the recipient chooses to donate it to a 501(c)(3) charity of their choice.”
There are hints to which phrase was used as the seed. Dr Jerry Solinas thinks he used something similar to “Jerry deserves a raise.
For the first couple decades of its existence, NASA was the epitome of an Old Boys Club; its astronaut ranks pulled exclusively from the Armed Services’ test pilot programs which, at that time, were exclusively staffed by men. Glass ceilings weren’t the only things broken when Sally Ride, Judy Resnik, Kathy Sullivan, Anna Fisher, Margaret “Rhea” Seddon and Shannon Lucid were admitted to the program in 1978 — numerous spaceflight systems had to be reassessed to accommodate a more diverse workforce. In The Six: The Untold Story of America’s First Women Astronauts, journalist Loren Grush chronicles the numerous trials and challenges these women faced — from institutional sexism to enduring survival training to navigating the personal pressures that the public life of an astronaut entails — in their efforts to reach orbit.
Above the Chisos Mountains sprawling across Big Bend National Park in West Texas, Kathy [Sullivan, PhD, third woman to fly in space and future head of the NOAA] sat in the back seat of NASA’s WB-57F reconnaissance aircraft as it climbed higher into the sky. The pilot, Jim Korkowski, kept his eye on the jet’s altimeter as they ascended. They’d just passed sixty thousand feet, and they weren’t done rising. It was a dizzyingly high altitude, but the plane was made to handle such extremes.
Inside the cockpit, both Kathy and Jim were prepared. They were fully outfitted in the air force’s high-altitude pressure suits. To the untrained observer, the gear looked almost like actual space suits. Each ensemble consisted of a bulky dark onesie, with thick gloves and a thick helmet. The combination was designed to apply pressure to the body as the high-altitude air thinned away and made it almost impossible for the human body to function.
The duo eventually reached their target height: 63,300 feet. At that altitude, their pressure suits were a matter of life and death. The surrounding air pressure was so low that their blood could start to boil if their bodies were left unprotected. But with the suits on, it was an uneventful research expedition. Kathy took images with a specialized infrared camera that could produce color photos, and she also scanned the distant terrain in various wavelengths of light.
They spent just an hour and a half over Big Bend, and the flight lasted just four hours in total. While it may have seemed a quick and easy flight, Kathy made history when she reached that final altitude above West Texas on July 1, 1979. In that moment, she flew higher than any woman ever had, setting an unofficial world aviation record.
The assignment to train with the WB-57 had scared her at first, but Kathy wound up loving those high-flying planes. “That was very fun, other than this little bit of vague concern that, ‘Hope this doesn’t mean I’m falling off the face of the Earth,’” Kathy said. The assignment took her on flights up north to Alaska and down south to Peru. As she’d hoped, she received full qualification to wear the air force’s pressure suits, becoming the first woman to do so. Soon, donning a full-body suit designed to keep her alive became second nature to her.
NASA officials had also sought her out to test a new piece of equipment they were developing for future Shuttle astronauts, one that would let people relieve themselves while in space. During the Apollo and Gemini eras, NASA developed a relatively complex apparatus for astronauts to pee in their flight suits. It was, in essence, a flexible rubber cuff that fit around the penis, which then attached to a collection bag. The condom-like cuffs came in “small,” “medium,” and “large” (though Michael Collins claimed the astronauts gave them their own terms: “extra large,” “immense,” and “unbelievable”). It was certainly not a foolproof system. Urine often escaped from beneath the sheath.
Cuffs certainly weren’t going to work once women entered the astronaut corps. While the Space Shuttle had a fancy new toilet for both men and women to use, the astronauts still needed some outlet for when they were strapped to their seats for hours, awaiting launch or reentry. And if one of the women was to do a spacewalk, she’d need some kind of device during those hours afloat. So, NASA engineers created the Disposable Absorption Containment Trunk (DACT). In its most basic form it was . . . a diaper. It was an easy fix in case astronauts needed to urinate while out of reach of the toilet. It was designed to absorb fecal matter, too, though the women probably opted to wait until they reached orbit for that.
Kathy was the best person to test it out. Often during her high-altitude flights, she’d be trapped in her pressure suit for hours on end, creating the perfect testing conditions to analyze the DACT’s durability. It worked like a charm. And although the first male Shuttle fliers stuck to the cuffs, eventually the DACT became standard equipment for everyone.
After accumulating hundreds of hours in these pressure suits, Kathy hoped to leverage her experience into a flight assignment, one that might let her take a walk outside the Space Shuttle one day. As luck would have it, she ran into Bruce McCandless II in the JSC gym one afternoon. He was the guy to know when it came to spacewalks. NASA officials had put him in charge of developing all the spacewalk procedures and protocols, and at times he seemed to live in the NASA pools. Plus, he was always conscripting one of Kathy’s classmates to do simulated runs with him in the tanks. Kathy wanted to be next. Projecting as much confidence as she could, she asked him to consider her for his next training run.
It worked. Bruce invited Kathy to accompany him to Marshall Space Flight Center in Alabama to take a dive in the tank there. The two would be working on spacewalk techniques that might be used one day to assemble a space station. However, the Space Shuttle suits still weren’t ready to use yet. Kathy had to wear Apollo moonwalker Pete Conrad’s suit, just like Anna had done during her spacewalk simulations. But while the suit swallowed tiny Anna, it was just slightly too small for Kathy, by about an inch. When she put it on, the suit stabbed her shoulders, while parts of it seemed to dig into her chest and back. She tried to stand up and nearly passed out. It took all her strength to walk over to the pool before she flopped into the tank. In the simulated weightless environment, the pain immediately evaporated. But it was still a crucial lesson in space-suit sizes. The suits have to fit their wearers perfectly if the spacewalk is going to work.
The session may have started off painfully, but once she began tinkering with tools and understanding how to maneuver her arms to shift the rest of her body, she was hooked. She loved spacewalking so much that she’d go on to do dozens more practice dives throughout training.
But it wasn’t enough to practice in the pool. She wanted to go orbital.

Bitcoin creator Satoshi Nakamoto may or may not be businessman Craig Wright, who in 2015 founded the blockchain-tech company nChain.
But nChain’s recently-departed CEO Christen Ager-Hanssen’s thinks Wright is not Satoshi — and that’s just the beginning. According to Forbes Ager-Hanssen went as far as “to leak emails suggesting former gambling billionaire Calvin Ayre, who has heavily backed the company doesn’t believe Wright, nChain’s chief scientist, is Satoshi Nakamoto.
The alleged email from Ayre begins by citing Wright’s “litigation disaster”…’
I have been operating under the assumption that you and Ramona have the keys and that you were simply pretending not to have them as part of some strategy that you have trapped yourself in. But now that we are looking at a situation where continuing to deny you have them ruins your life and damages your supporters, I am forced to make a tough decision… There is zero reason to continue to pretend you do not have the keys if you really have them… So either you are a moron for intentionally losing this case, or you are a moron for actually not having the keys… either way, I am not following you over the cliff…
But Ager-Hanssen also shared some thoughts of his own:
I can confirm I have departed from nChain Global as its Group CEO with immediate effect after reporting several serious issues to the board of nChain Group including what I believe is a conspiracy to defraud nChain shareholders orchestrated by a significant shareholder. I also had concerns about the ultimate beneficiary shareholder and the real people behind DW Discovery fund registered in Cayman. The chairman also took instructions from shadow directors which I didn’t accept.
I have also reported that I have found compelling evidence that Dr Craig Wright has manipulated documents with the aim to deceive the court he is Satoshi. I’m today myself convinced that Dr Craig Wright is NOT Satoshi and I’m persuaded he will lose all his legal battles. The board didn’t take action and my job becomes clearly untenable. One of the things I recommended the Chairman of the board was to sack Dr Craig Wright.
I feel sorry for all the great people that work in the company but I don’t want to be part of something I clearly don’t believe in. #faketoshi
Forbes also notes an X (Twitter) account calling itself “Satoshi Nakamoto” with the handle @Satoshi has posted for the first time since 2018 — though X’s community notes feature added: “This isn’t the real Satoshi Nakamoto, creator of bitcoin. Its an account related to Craig Wright, who claims to be Satoshi with no material proof.”

Lamplighters League is a modern XCOM-style turn-based strategy game with a Weird War-ish, Indiana Jones-like feel, a light stealth element, and it’s made by the folks who made Battletech and the Shadowrun Returns series. If you pay for Game Pass, or you see this game at any price that feels reasonable (including its debut $50), that should tell you enough about whether to try it. I think you should.
I wanted to get that out of the way because I have some nits to pick with Lamplighters League, some technical and some tactical. But I don’t want to lose sight of how excited I am to have a meaty new tactics game to sink into, especially one based on an original, if heavily referential, world. If you’re a fan of tile-based movements, two actions per turn, home bases full of upgrade potential, and engaging little interactions between your troops, you don’t get that many solid games like this per year, so take note of Lamplighters League. The number of years between XCOM titles is getting longer, not shorter—we need some reserves.

Amazon is set to launch two satellite prototypes for its Project Kuiper network, which will eventually number more than 3,200 orbiters. Project Kuiper could become a rival to SpaceX’s Starlink constellation, which is now nearly 4,800 strong. Amazon’s launch is planned for 2 pm Eastern time today, with a backup launch window tomorrow. This rapid growth of the satellite industry has come at a cost for astronomers and fans of the night sky, as two new studies and panels at an international astronomy conference stressed this week.
All spacecraft in low-Earth orbit reflect sunlight, and some glint enough to be visible to the naked eye—artificial constellations that compete with stellar ones. Satellites can cause problems for astronomers when they streak across images, interfere with radio observations, or make hard-earned data less scientifically useful. By one estimate, there could be some 100,000 satellites swarming the skies in the 2030s. While scientists are mainly concerned about this aggregate effect, some individual satellites are very bright indeed. A study published in the journal Nature this week shows that a prototype of AST SpaceMobile’s BlueBird swarm has become one of the brightest objects in the heavens. Another study documents how even deliberately darkened satellites are still twice as bright—if not more—than the limit astronomers have called for to minimize effects on space science.
Such concerns prompted a major conference this week, organized by the International Astronomical Union’s Centre for the Protection of the Dark and Quiet Sky from Satellite Constellation Interference, known as CPS. It’s being held in the Canary Islands, where there are several observatories. It’s the first in-person meeting of its kind, bringing together scores of astronomers, as well as satellite industry representatives, advocates of Indigenous and environmental perspectives, and policy experts.

It started when Linux blogger Bryan Lunduke complained about how the Linux Foundation was reducing the six-year long-term support (LTS) window for the Linux kernel to two years. Lunduke argued that the Foundation seemed more interested in funding compliance best practices — as well as artificial intelligence and blockchain projects.
In an online discussion, Linux kernel maintainer Greg Kroah-Hartman had this response:
Did anyone think to actually ask the developer who is maintaining the long-term support kernel versions why he made that change (back in February?), i.e. me…? No, I guess that would take too much effort, and wouldn’t result in such a click-bait headline.
“LTS kernels are no longer supported for 6 years because it turns out no one used them.” doesn’t have that same fun sound…
In a second comment Kroah-Hartman also clarified that in fact “The amount of resources and other stuff that the Linux Foundation provides to the Linux kernel community has increased over the years, including last year. ”
Just because new people are brought in with new projects (that the LF member companies want to host) does not mean that somehow less is being given to the kernel community at all. It is not a zero-sum game here at all, that’s not how the LF works in any way.
Again, this would have been easy to verify if someone just asked us.
So to repeat, no “abandonment” is happening here at all, the opposite is happening, just like it has for the entirety of the Linux Foundation’s existence, support has grown every year.

“Python 3 was by far the choice over Python 2 in a late-2022 survey of more than 23,000 Python developers,” reports InfoWorld, “but the percentage of respondents using Python 2 actually ticked up compared to the previous year.”
Results of the sixth annual Python Developers Survey, conducted by the Python Software Foundation and software tools maker JetBrains, were released September 27. The Python Developers Survey 2022 report indicates that 93% of respondents had adopted Python 3, while only 7% were still using Python 2.
In the 2021 survey, though, 95% used Python 3 while 5% used Python 2. In 2020, Python 3 held a 94% to 6% edge. Dating back to 2017, 75% used Python 3 and 25% used Python 2…
The 2022 report said 29% of respondents still use Python 2 for data analysis, 24% use Python 2 for computer graphics, and 23% used Python 2 for devops. The survey also found that 45% of respondents are still using Python 3.10, which arrived two years ago, while just 2% still use Python 3.5 or lower. (Python 3.11 was released October 24, 2022, right when the survey was being conducted.)
Other findings from the survey:
21% said they used Python for work only, while 51% said they used it for work and personal/educational use or side projects, and 21% said they used Python only for personal projects.
85% of respondents said Python was their main language (rather than a secondary language).
The survey also gives the the top “secondary languages” for the surveyed Python developers as JavaScript (37%), HTML/CSS (37%), SQL (35%), Bash/Shell (32%), and then C/C++ (27%).
When asked what they used Python for most, 22% said “Web Development”, 18% said “Data Analysis,” 12% said “Machine Learning,” and 10% said “DevOps/System Administration/Writing Automation Scripts.”
An anonymous reader writes: Amidst a winter marked by scarce gas supplies, the German government has opted to retain its lignite coal power plants on standby for another season. Originally, Germany had planned a phased shutdown of coal plants in exchange for a portion of the government’s €40 billion coal phase-out fund. However, last year, disruptions in Russian gas supplies post-Ukraine war prompted an emergency decision to keep coal plants operational. This measure is now extended for the upcoming winter, maintaining 1.9 GWs of lignite capacity alongside the existing 45 GW of coal power plants. The primary purpose of these lignite plants is to alleviate gas demand during peak times and stabilize prices. Despite the economic benefits, the move raises environmental concerns, given lignite’s status as a major climate polluter. The government acknowledges this and plans to assess the additional carbon emissions resulting from keeping coal plants on standby, estimated to be between 2.5 and 5.6 tonnes of CO2. The German government emphasized the persistence of the goal to ideally complete the coal phase-out by 2030 and meet climate targets.
