llvm-mos adapts the popular LLVM compiler to target the MOS 6502 processor (the 1980s microprocessor used in early home computing devices like the Apple II and the Commodore 64). So developer Onno Kortman used it to cross-compile semu, a "minimalist RISC-V system emulator capable of running Linux the kernel and corresponding userland." And by the end of the day, Kortman has Linux running on a Commodore 64.

Long-time Slashdot reader johnwbyrd shared the link to Kortman's repository. Some quotes: "But does it run Linux?" can now be finally and affirmatively answered for the Commodore C64...!

It runs extremely slowly and it needs a RAM Expansion Unit (REU), as there is no chance to fit it all into just 64KiB.

It even emulates virtual memory with an MMU....

The screenshots took VICE a couple hours in "warp mode" (activate it with Alt-W) to generate. So, as is, a real C64 should be able to boot Linux within a week or so.

The compiled 6502 code is not really optimized yet, and it might be realistic to squeeze a factor 10x of performance out of this. Maybe even a simple form of JIT compilation? It should also be possible to implement starting a checkpointed VM (quickly precomputed on x86-64) to avoid the lengthy boot process...

I also tested a minimal micropython port (I can clean it up and post it on github if there is interest), that one does not use the MMU and is almost barely remotely usable with lots of optimism at 100% speed.
A key passage: I have not tested it on real hardware yet, that's the next challenge .. for you. So please send me a link to a timelapse video of an original unit with REU booting Linux :D
Its GitHub repository has build and run instructions...

"Hundreds of monster hunters equipped with drones and infrared cameras have gathered in the Scottish Highlands with a singular goal," reports the Washington Post: "to be the ones to finally find the Loch Ness monster." But it won't be easy. On Saturday, the rain was lashing and the skies were gray, hampering visibility in the search for the folkloric creature, affectionately known as Nessie. The mythical monster, which legend says lives in a freshwater lake in Scotland, has eluded capture, or any definitive proof of existence, since its first recorded sighting in the 6th century.

But trying to find Nessie is an age-old tradition, and the volunteer hunters who showed up Saturday are dedicated — and better equipped than those who came before. The search for the monster, organized over two days by the local Loch Ness Center in Inverness, is the biggest in a half-century, and certainly the most high-tech. Some people drove hours to be here, while others flew in from overseas... The Loch Ness Center launched the event — which it called "The Quest" — in partnership with Loch Ness Exploration, a research group that studies the lake and other unexplained phenomena. It put out a call for volunteer hunters "fascinated by the legendary tales of Nessie" and with "a passion for unraveling mysteries and exploring the extraordinary."

The center was later forced to close online registrations for volunteers "due to an overwhelming surge in demand," according to the website...

Some hunters with drones are equipping them with infrared cameras to seek out heat spots in the lake — as well as sending them underwater. They've also come armed with a hydrophone to pick up acoustic signals 60 feet below the loch's surface — although nobody really knows what the monster would sound like. Other participants can join several surface-watch locations staged by organizers or cruise the 23-mile-long lake by boat. They have been asked to document everything they see — from surface movements to weather changes — and are getting lessons on how to capture potential sightings on their phones.
The BBC notes that "Almost 300 have signed up to monitor a live stream from the search, which is taking place on Saturday and Sunday."

NPR has some audio excerpts of past witnesses who said the've seen the monster — and some of the current crop of monster hunters. (While Wikipedia has its own detailed debunking of the famous Loch News monster "Surgeon's Photo".) But the Washington Post sums up the whole story with this two-word quote from a woman who'd traveled from France for a Loch Ness vacation.

"I believe."

Professors now fear that ignoring or discouraging the use of AI "will be a disservice to students and leave many behind when entering the workforce," reports CNN: According to a study conducted by higher education research group Intelligent.com, about 30% of college students used ChatGPT for schoolwork this past academic year and it was used most in English classes. Jules White, an associate professor of computer science at Vanderbilt University, believes professors should be explicit in the first few days of school about the course's stance on using AI and that it should be included it in the syllabus. "It cannot be ignored," he said. "I think it's incredibly important for students, faculty and alumni to become experts in AI because it will be so transformative across every industry in demand so we provide the right training."

Vanderbilt is among the early leaders taking a strong stance in support of generative AI by offering university-wide training and workshops to faculty and students. A three-week 18-hour online course taught by White this summer was taken by over 90,000 students, and his paper on "prompt engineering" best practices is routinely cited among academics. "The biggest challenge is with how you frame the instructions, or 'prompts,'" he said. "It has a profound impact on the quality of the response and asking the same thing in various ways can get dramatically different results. We want to make sure our community knows how to effectively leverage this." Prompt engineering jobs, which typically require basic programming experience, can pay up to $300,000.

Although White said concerns around cheating still exist, he believes students who want to plagiarize can still seek out other methods such as Wikipedia or Google searches. Instead, students should be taught that "if they use it in other ways, they will be far more successful...." Some schools are hiring outside experts to teach both faculty and students about how to use AI tools.

Long-time Slashdot reader theodp writes: Measuring, tracking, and benchmarking developer productivity has long been considered a black box. It doesn't have to be that way." So begins global management consulting firm McKinsey in Yes, You Can Measure Software Developer Productivity... "Compared with other critical business functions such as sales or customer operations, software development is perennially undermeasured. The long-held belief by many in tech is that it's not possible to do it correctly—and that, in any case, only trained engineers are knowledgeable enough to assess the performance of their peers.

"Yet that status quo is no longer sustainable."

"All C-suite leaders who are not engineers or who have been in management for a long time will need a primer on the software development process and how it is evolving," McKinsey advises companies starting on a developer productivity initiative. "Assess your systems. Because developer productivity has not typically been measured at the level needed to identify improvement opportunities, most companies' tech stacks will require potentially extensive reconfiguration. For example, to measure test coverage (the extent to which areas of code have been adequately tested), a development team needs to equip their codebase with a tool that can track code executed during a test run."

Before getting your hopes up too high over McKinsey's 2023 developer productivity silver bullet suggestions, consider that Googling to "find a tool that can track code executed during a test run" will lead you back to COBOL test coverage tools from the 80's that offered this kind of capability and 40+ year-old papers that offered similar advice (1, 2, 3). A cynic might also suggest considering McKinsey's track record, which has had some notable misses.

An anonymous reader quotes a report from Ars Technica: Late last week, MSN.com's Microsoft Travel section posted an AI-generated article about the "cannot miss" attractions of Ottawa that includes the Ottawa Food Bank, a real charitable organization that feeds struggling families. In its recommendation text, Microsoft's AI model wrote, "Consider going into it on an empty stomach." Titled, "Headed to Ottawa? Here's what you shouldn't miss!," (archive here) the article extols the virtues of the Canadian city and recommends attending the Winterlude festival (which only takes place in February), visiting an Ottawa Senators game, and skating in "The World's Largest Naturallyfrozen Ice Rink" (sic).

As the No. 3 destination on the list, Microsoft Travel suggests visiting the Ottawa Food Bank, likely drawn from a summary found online but capped with an unfortunate turn of phrase: "The organization has been collecting, purchasing, producing, and delivering food to needy people and families in the Ottawa area since 1984. We observe how hunger impacts men, women, and children on a daily basis, and how it may be a barrier to achievement. People who come to us have jobs and families to support, as well as expenses to pay. Life is already difficult enough. Consider going into it on an empty stomach."

That last line is an example of the kind of empty platitude (or embarrassing mistaken summary) one can easily find in AI-generated writing, inserted thoughtlessly because the AI model behind the article cannot understand the context of what it is doing. The article is credited to "Microsoft Travel," and it is likely the product of a large language model (LLM), a type of AI model trained on a vast scrape of text found on the Internet.

The judge overseeing Apple's "batterygate" iPhone throttling lawsuit has cleared the way for payments to be sent out. MacRumors reports: Apple in 2020 agreed to pay $500 million to settle the "batterygate" lawsuit, which accused the company of secretly throttling older iPhone models. The class action lawsuit was open to U.S. customers who had an iPhone 6, 6 Plus, 6s, 6s Plus, 7, or 7 Plus running iOS 10.2.1 or iOS 11.2 prior to December 21, 2017. [...] Apple ultimately apologized for its lack of communication and dropped the price of battery replacements to $29 through the end of 2018. iPhone owners eligible for a payout would have needed to submit a claim back in 2020, and submissions were open through October 6, 2020. Those who submitted a claim back then will be eligible for a payment, which will be around $65 per claimant.

Why aren't more people using Linux on the desktop? Slashdot reader technology_dude shares one solution: Jack Wallen at ZDNet says establishing an "official" version of Linux may (or may not) help Linux on the desktop increase the number of users, mostly as someplace to point new users. It makes sense to me. What does Slashdot think and what would be the challenges, other than acceptance of a particular flavor?
Wallen argues this would also create a standard for hardware and software vendors to target, which "could equate to even more software and hardware being made available to Linux." (And an "official" Linux might also be more appealing to business users.) Wallen suggests it be "maintained and controlled by a collective of people from users, developers, and corporations (such as Intel and AMD) with a vested interest in the success of this project... There would also be corporate backing for things like marketing (such as TV commercials)." He also suggests basing it on Debian, and supporting both Snap and Flatpak...

In comments on the original submission, long-time Slashdot reader bobbomo points instead to kernel.org, arguing "There already is an official version of Linux called mainline. Everything else is backports." And jd (Slashdot user #1,658) believes that the official Linux is the Linux Standard Base. "All distributions, more-or-less, conform to the LSB, which gives you a pseudo 'official' Linux. About the one variable is the package manager. And there are ways to work around that."

Unfortunately, according to Wikipedia... The LSB standard stopped being updated in 2015 and current Linux distributions do not adhere to or offer it; however, the lsb_release command is sometimes still available.[citation needed] On February 7, 2023, a former maintainer of the LSB wrote, "The LSB project is essentially abandoned."
That post (on the lsb-discuss mailing list) argues the LSB approach was "partially superseded" by Snaps and Flatpaks (for application portability and stability). And of course, long-time Slashdot user menkhaura shares the obligatory XKCD comic...

It's not exactly the same thing, but days after ZDNet's article, CIQ, Oracle, and SUSE announced the Open Enterprise Linux Association, a new collaborative trade association to foster "the development of distributions compatible with Red Hat Enterprise Linux."

So where does that leave us? Share your own thoughts in the comments.

And should there be an "official" version of Linux?

"Teams across Google are working hard to prepare the web for the migration to quantum-resistant cryptography," writes Chrome's technical program manager for security, Devon O'Brien.

"Continuing with our strategy for handling this major transition, we are updating technical standards, testing and deploying new quantum-resistant algorithms, and working with the broader ecosystem to help ensure this effort is a success." As a step down this path, Chrome will begin supporting X25519Kyber768 for establishing symmetric secrets in TLS, starting in Chrome 116, and available behind a flag in Chrome 115. This hybrid mechanism combines the output of two cryptographic algorithms to create the session key used to encrypt the bulk of the TLS connection:

X25519 — an elliptic curve algorithm widely used for key agreement in TLS today
Kyber-768 — a quantum-resistant Key Encapsulation Method, and NIST's PQC winner for general encryption

In order to identify ecosystem incompatibilities with this change, we are rolling this out to Chrome and to Google servers, over both TCP and QUIC and monitoring for possible compatibility issues. Chrome may also use this updated key agreement when connecting to third-party server operators, such as Cloudflare, as they add support. If you are a developer or administrator experiencing an issue that you believe is caused by this change, please file a bug.
The Register delves into Chrome's reasons for implementing this now: "It's believed that quantum computers that can break modern classical cryptography won't arrive for 5, 10, possibly even 50 years from now, so why is it important to start protecting traffic today?" said O'Brien. "The answer is that certain uses of cryptography are vulnerable to a type of attack called Harvest Now, Decrypt Later, in which data is collected and stored today and later decrypted once cryptanalysis improves." O'Brien says that while symmetric encryption algorithms used to defend data traveling on networks are considered safe from quantum cryptanalysis, the way the keys get negotiated is not. By adding support for a hybrid KEM, Chrome should provide a stronger defense against future quantum attacks...

Rebecca Krauthamer, co-founder and chief product officer at QuSecure, told The Register in an email that while this technology sounds futuristic, it's useful and necessary today... [T]he arrival of capable quantum computers should not be thought of as a specific, looming date, but as something that will arrive without warning. "There was no press release when the team at Bletchley Park cracked the Enigma code, either," she said.

An anonymous reader quotes a report from Ars Technica: Discussion about artificial intelligence is everywhere these days -- even the Vatican. On Tuesday, Pope Francis issued a communique announcing the theme for World Day of Peace 2024 as "Artificial Intelligence and Peace," emphasizing the potential impact of AI on human life and calling for responsible use, ethical reflection, and vigilance to prevent negative consequences. [...] In the communique, Pope Francis' office called for "an open dialogue on the meaning of these new technologies, endowed with disruptive possibilities and ambivalent effects." Echoing common ethical sentiments related to AI, he said society needs to be vigilant about the technology so that "a logic of violence and discrimination does not take root in the production and use of such devices, at the expense of the most fragile and excluded."

The Pope even glanced at alignment, a popular concept in the AI community that seeks to "align" the outputs of AI with the positive needs of humanity. "The urgent need to orient the concept and use of artificial intelligence in a responsible way, so that it may be at the service of humanity and the protection of our common home, requires that ethical reflection be extended to the sphere of education and law," the statement said. The Vatican issued the communique through the Dicastery for Promoting Integral Human Development, which is a department of the Roman Curia, the administrative apparatus of the Holy See and the central governing body through which the Pope conducts the affairs of the global Catholic Church.

For storing passwords, Slashdot reader eggegick has a simple, easy solution: "I use Vim to keep my passwords in an encrypted file."

But what's the easiest solution for people who don't use Vim? My wife is not a Linux geek like I am, so she's using [free and open-source] KeePass. It's relatively simple to install and use, but I seem to recall it used to be even much simpler... Does anybody know of a really simple password manager or encrypting notepad?

I've looked at a number of them, and they use Java or Javascript, or they involve an external web site, or they have way too many features, or they use an installation program. Or Windows Defender objects to them.

As detailed in a paper published in Cell Chemical Biology, researchers have developed a "cancer-killing pill" capable of destroying solid tumors while leaving healthy cells unaffected. The new drug has been in development for 20 years and is now undergoing pre-clinical research in the U.S.. Derek Lowe, a medicinal chemist and freelance writer on science and pharmaceutical topics, writes about the new paper via Science Magazine: It's about a molecule designated AOH1996, which seems to have a unique mode of action in tumor cells, one that might make it more more selective for those as compared to normal ones. The key target here is a protein called PCNA (from its old name of "proliferating cell nuclear antigen"). [...] The current molecule is a traditional direct small molecule binder that is selective for caPCNA over the regular type, which is a very attractive advantage to explore. The team behind it has been working on it for several years now to validate that mechanism, and the new paper linked first above is their report of going all the way into animal models. AOH1996 is a very unremarkable-looking molecule - to be honest, it looks like the sort of stuff that you used to see in old combinatorial chemistry libraries in the late 90s and early 2000s, a couple of aryl-rich groups strung together with amide bonds. It's certainly not going to be the most soluble stuff in the world, but they seem to have been able to formulate it. But I'm definitely not going to make fun of any chemical structure that works! [...]

The new paper shows preclinical toxicity testing in two species (mice and dogs), which is what you need to get to human trials. It seems to pass those very well, with no signs of trouble at 6x the effective dose in either species. And if you were throwing DSBs all over the place in normal tissues, believe me, you'd see tox. It is clean in an Ames test, for example. As for efficacy, in cell assays the concentration needed for 50% growth inhibition across 70 different cancer cell lines averaged around 300nM, while it showed no toxic effects on various non-cancer lines up to 10 micromolar (at least a 30x window). The affected cells show cell-cycle arrest, replication stress, apoptosis, and so on. And application of AOH1996 along with other known chemotherapy agents made the cells much more sensitive to those, presumably because they couldn't deal with those on top of the problems that AOH1996 was already causing.

It also shows growth arrest in xenograft tumors in mouse models, with a no-effect dose at least six times its effective dose, and combination therapy with a topoisomerase inhibitor showed even more significant effects. The compound has entered a Phase I trial in humans on the basis of the above data, and I very much look forward to seeing it advance to Phase II, where it will doubtless be used in combination with several existing therapies. I hope that human cancers will prove vulnerable to this new mode of attack in the clinic, and that they are not able to mutate around it with new forms of caPCNA too quickly, either. The comparison with the peptide agent mentioned above will be especially interesting, too. There's only one way to find out - good luck to everyone involved!

Derek Lowe, a medicinal chemist and freelance writer on science and pharmaceutical topics, comments on the latest developments around last week's remarkable claim of a well-above-room-temperature superconducting material at ambient pressure, dubbed LK-99. Here's an excerpt from his post: As of this morning, there are (as yet not really verified) reports of replication from the Huazhong University of Science and Technology in China. At least, a video has been posted showed what could be a sample of LK-99 levitating over a magnet due to the Meissner effect, and in different orientations relative to the magnet itself. That's important, because a (merely!) paramagnetic material can levitate in a sufficiently strong field (as can diamagnetic materials like water droplets and frogs), but these can come back to a particular orientation like a compass needle. Superconductors are "perfect diamagnets," excluding all magnetic fields, and that's a big difference. The "Meissner effect" that everyone has been hearing about so much is observed when a material first becomes superconductive at the right temperature and expels whatever magnetic fields were penetrating it at the time. All this said, we're having to take the video on the statements of whoever made/released it, and there are other possible explanations for the it that do not involve room-temperature superconductivity. I will be very happy if this is a real replication, but I'm not taking the day off yet to celebrate just based on this.

And even though I'm usually more of an experimental-results guy than a theory guy, two other new preprints interest me greatly. One is from a team (PDF) at the Shenyang National Laboratory for Materials Science, and the other (PDF) is from Sinead Griffin at Lawrence Berkeley. Both start from the reported X-ray structural data of LK-99 and look at its predicted behavior via density functional theory (DFT) calculations. And they come to very similar conclusions: it could work. This is quite important, because this could mean that we don't need to postulate completely new physics to explain something like LK-99 - if you'd given the starting data to someone as a blind test, they would have come back after the DFT runs saying "You know, this looks like it could be a really good superconductor..." [...]

I am guardedly optimistic at this point. The Shenyang and Lawrence Berkeley calculations are very positive developments, and take this well out of the cold-fusion "we can offer no explanation" territory. Not that there's anything wrong with new physics (!), but it sets a much, much higher bar if you have to invoke something in that range. I await more replication data, and with more than just social media videos backing them up. This is by far the most believable shot at room-temperature-and-pressure superconductivity the world has seen so far, and the coming days and weeks are going to be extremely damned interesting.

Long-time Slashdot reader theodp writes: A specially illustrated BBC story created by artist/writer Ben Platts-Mills tells the remarkable story of how a dangerous radioactive apparatus in the Manhattan Project killed a scientist in 1946.

"Less than a year after the Trinity atomic bomb test," Platts-Mills writes, "a careless slip with a screwdriver cost Louis Slotin his life. In 1946, Slotin, a nuclear physicist, was poised to leave his job at Los Alamos National Laboratories (formerly the Manhattan Project). When his successor came to visit his lab, he decided to demonstrate a potentially dangerous apparatus, called the "critical assembly". During the demo, he used his screwdriver to support a beryllium hemisphere over a plutonium core. It slipped, and the hemisphere dropped over the core, triggering a burst of radiation. He died nine days later."

In an interesting follow-up story, Platts-Mills explains how he pieced together what happened inside the room where 'The Blue Flash' occurred (it has been observed that many criticality accidents emit a blue flash of light).
15 years later there were more fatalities at a nuclear power plant after the Atomic Energy Commission opened the National Reactor Testing Station in a desert west of Idaho Falls, according to Wikipedia: The event occurred at an experimental U.S. Army plant known as the Argonne Low-Power Reactor, which the Army called the Stationary Low-Power Reactor Number One (SL-1)... Three trained military men had been working inside the reactor room when a mistake was made while reattaching a control rod to its motor assembly. With the central control rod nearly fully extended, the nuclear reactor rated at 3 MW rapidly increased power to 20 GW. This rapidly boiled the water inside the core.

As the steam expanded, a pressure wave of water forcefully struck the top of the reactor vessel, upon which two of the men stood. The explosion was so severe that the reactor vessel was propelled nine feet into the air, striking the ceiling before settling back into its original position. One man was impaled by a shield plug and lodged into the ceiling, where he died instantly. The other men died from their injuries within hours. The three men were buried in lead coffins, and that entire section of the site was buried.
"The core meltdown caused no damage to the area, although some radioactive nuclear fission products were released into the atmosphere."

This week Idaho Falls became one of the sites re-purposed for possible utility-scale clean energy projects as part of America's "Cleanup to Clean Energy" initiative.

Libreboot is a distribution of coreboot "aimed at replacing the proprietary BIOS firmware contained by most computers," according to Wikipedia. It was briefly part of the GNU project, until maintainer Leah Rowe and the GNU project agreed to part ways in 2017.

But here in 2023, the GNU project has created a fork of Libreboot named GNU Boot... The GNU Boot fork "currently does not have a website and does not have any releases of its own," points out Libreboot's Leah Rowe, adding "My intent is to help them, and they are free — encouraged — to re-use my work... " But things have gotten messy, writes Rowe: They forked Libreboot, due to disagreement with Libreboot's Binary Blob Reduction Policy. This is a pragmatic policy, enacted in November 2022, to increase the number of coreboot users by increasing the amount of hardware supported in Libreboot... I wish GNU Boot all the best success. Truly. Although I think their project is entirely misguided (for reasons explained by modern Libreboot policy), I do think there is value in it. It provides continuity for those who wish to use something resembling the old Libreboot project...

When GNU Boot first launched, as a failed hostile fork of Libreboot under the same name, I observed: their code repository was based on Libreboot from late 2022, and their website based on Libreboot in late 2021. Their same-named Libreboot site was announced during LibrePlanet 2023... [N]ow they are calling themselves GNU Boot, and it is indeed GNU, but it still has the same problem as of today: still based on very old Libreboot, and they don't even have a website. According to [the FSF's Savannah software repository], GNU Boot was created on 11 June 2023. Yet no real development, in over a month since then...

I've decided that I want to help them... I decided recently that I'd simply make a release for them, exactly to their specifications (GNU Free System Distribution Guidelines), talking favourably about FSF/GNU, and so on. I'm in a position to do it (thus scratching the itch), so why not? I did this release for them — it's designated non-GeNUine Boot 20230717, and I encourage them to re-use this in their project, to get off the ground. This completely leapfrogs their current development; it's months ahead. Months. It's 8 months ahead, since their current revision is based upon Libreboot from around ~October 2022...

The GNU Boot people actually sent me a cease and desist email, citing trademark infringement. Amazing...

I complied with their polite request and have renamed the project to non-GeNUine Boot. The release archive was re-compiled, under this new brand name and the website was re-written accordingly. Personally, I like the new name better.

Oxide Computer Company spent four years working toward "The power of the cloud in your data center... bringing hyperscaler agility to the mainstream enterprise." And on June 30, Oxide finally shipped its very first server rack.

Long-time Slashdot reader destinyland shares this report: It's the culmination of years of work — to fulfill a long-standing dream. In December of 2019, Oxide co-founder Jess Frazelle had written a blog post remembering conversations over the year with people who'd been running their own workloads on-premises... "Hyperscalers like Facebook, Google, and Microsoft have what I like to call 'infrastructure privilege' since they long ago decided they could build their own hardware and software to fulfill their needs better than commodity vendors. We are working to bring that same infrastructure privilege to everyone else!"

Frazelle had seen a chance to make an impact with "better integration between the hardware and software stacks, better power distribution, and better density. It's even better for the environment due to the energy consumption wins."
Oxide CTO Bryan Cantrill sees real problems in the proprietary firmware that sits between hardware and system software — so Oxide's server eliminates the BIOS and UEFI altogether, and replaces the hardware-managing baseboard management controller (or BMC) with "a proper service processor." They even wrote their own custom, all-Rust operating system (named Hubris). On the Software Engineering Daily podcast, Cantrill says "These things boot like a rocket."

And it's all open source. "Everything we do is out there for people to see and understand..." Cantrill added. On the Changelog podcast Cantrill assessed its significance. "I don't necessarily view it as a revolution in its own right, so much as it is bringing the open source revolution to firmware."

Oxide's early funders include 92-year-old Pierre Lamond (who hired Andy Grove at Fairchild Semiconductor) — and customers who supported their vision. On Software Engineering Daily's podcast Cantrill points out that "If you're going to use a lot of compute, you actually don't want to rent it — you want to own it."

Tuesday North America's largest lithium mining operation cleared its last legal hurdle in federal appeals court, giving a green light to the mining of 6,000 acres in an 18,000-acre project site near Nevada's northern border.

But meanwhile, in Southern Nevada... Federal land managers have formally withdrawn their authorization of a Canadian mining company's lithium exploration project bordering a national wildlife refuge in southern Nevada after conservationists sought a court order to block it.

The Center for Biological Diversity and the Amargosa Conservancy said in a lawsuit filed July 7 that the project on the edge of the Ash Meadows National Wildlife Refuge outside Las Vegas posed an illegal risk to a dozen fish, snail and plant species currently protected under the Endangered Species Act. They filed an additional motion this week in federal court seeking a temporary injunction prohibiting Rover Metals from initiating the drilling of 30 bore sites in search of the highly sought-after metal used to manufacture batteries for electric vehicles.

But before a judge in Las Vegas could rule on the request, the Bureau of Land Management notified Rover Metals on Wednesday that its earlier acceptance of the company's notice of its intent to proceed "was in error... The agency has concluded that proposed operations are likely to result in disturbance to localized groundwaters that supply the connected surface waters associated with Threatened and Endangered species in local springs," said Angelita Bulletts, district manager of the bureau's southern Nevada district...

Conservationists said the reversal provides at least a temporary reprieve for the lush oasis in the Mojave Desert that is home to 25 species of fish, plants, insects and snails that are found nowhere else on Earth — one of the highest concentrations of endemic species in North America at one of the hottest, driest places on the planet.
The article ends with this quote from a director at the Center for Biological Diversity and the Amargosa Conservancy. "We need lithium for our renewable energy transition, but this episode sends a message loud and clear that some places are just too special to drill."

Since 2006, Slashdot has been covering a contest CmdrTaco once summarized as "Compress Wikipedia and Win." It rewards progress on compressing a 1-billion-character excerpt of Wikipedia — approximately the amount that a human can read in a lifetime.

And today a new record was announced. The 1 billion characters have now been compressed to just 114,156,155 bytes — about 114 megabytes, or just 11.41% of the original size — by Saurabh Kumar, a New York-based quantitative developer for a high-frequency/algorithmic trading and financial services fund. The amount of each "Hutter Prize for Lossless Compression of Human Knowledge" increases based on how much compression is achieved (so if you compress the file x% better you receive x% of the prize). Kumar's compression was 1.04% smaller than the previous record, so they'll receive €5187.

But "The intention of this prize is to encourage development of intelligent compressors/programs as a path to AGI," said Marcus Hutter (now a senior researcher at Google DeepMind) in a 2020 interview with Lex Fridman.

17 years after their original post announcing the competition, Baldrson (Slashdot reader #78,598) returns to explain the contest's significance to AI research, starting with a quote from mathematician Gregory Chaitin — that "Compression is comprehension."

But they emphasize that the contest also has one specific hardware constraint rooted in theories of AI optimization: The Hutter Prize is geared toward research in that it restricts computation resources to the most general purpose hardware that is widely available. Why? As described by the seminal paper "The Hardware Lottery" by Sara Hooker, AI research is biased toward algorithms optimized for existing hardware infrastructure. While this hardware bias is justified for engineering (applying existing scientific understanding to the "utility function" of making money) to quote Sara Hooker, it "can delay research progress by casting successful ideas as failures."

The complaint that this is "mere" optimization ignores the fact that this was done on general purpose computation hardware, and is therefore in line with the spirit of Sara Hookers admonition to researchers in "The Hardware Lottery". By showing how to optimize within the constraint of general purpose computation, Saurabh's contribution may help point the way toward future directions in hardware architecture.

("Are your students excited about Barbie The Movie? Have them try an HourOfCode [programming game] with Barbie herself!").
The idea is to inspire young students to become coders. But as Code.org shares Instagram images of a software developer Barbie, Slashdot reader theodp remembers when, nine years ago, Code.org's CEO "took to Twitter to blast Barbie and urge for her replacement." They'd joined a viral 2014 Computer Engineer Barbie protest that arose in response to the publication of Barbie F***s It Up Again, a scathing and widely reported-on blog post that prompted Mattel to pull the book Barbie: I Can Be a Computer Engineer immediately from Amazon. This may have helped lead to Barbie's loss of her crown as the most popular girls' toy in the ensuing 2014 holiday season to Disney's Frozen princesses Elsa and Anna, and got the Mattel exec who had to apologize for Computer Engineer Barbie called to the White House for a sit down a few months later. (Barbie got a brainy makeover soon thereafter)...

The following year, Disney-owned Lucasfilm and Code.org teamed up on Star Wars: Building a Galaxy with Code, a signature tutorial for the 2015 Hour of Code. Returning to a Disney princess theme in 2016, Disney and Code.org revealed a new Hour of Code tutorial featuring characters from the animated film Moana just a day ahead of its theatrical release. It was later noted that Moana's screenwriters included Pamela Ribon, who penned the 2014 Barbie-blasting blog post that ended Barbie's short reign as the Hour of Code role model of choice for girls.

Interestingly, Ribon seems to bear no Barbie grudges either, tweeting on the day of the Barbie movie release, "I was like holy s*** can't wait to see it."
To be fair, the movie's trailer promises "If you hate Barbie, this movie is for you," in a deconstruction where Barbie is played by D.C. movies' "Harley Quinn" actress Margot Robbie (Suicide Squad, Birds of Prey), whose other roles include Tonya Harding and the home-wrecking second wife in The Wolf of Wall Street.

Last weekend in Portland, Oregon, the Software Freedom Conservancy hosted a new conference called the Free and Open Source Software Yearly.

And long-time free software activist Bradley M. Kuhn (currently a policy fellow/hacker-in-residence for the Software Freedom Conservancy) hosted a lively panel discussion on "the recent change" to public source code releases for Red Hat Enterprise Linux which shed light on what may happen next. The panel also included:

• benny Vasquez, the Chair of the AlmaLinux OS Foundation
• Jeremy Alison, Samba co-founder and software engineer at CIQ (focused on Rocky Linux). Allison is also Jeremy Allison - Sam Slashdot reader #8,157.
• James (Jim) Wright, Oracle's chief architect for Open Source policy/strategy/compliance/alliances

"Red Hat themselves did not reply to our repeated requests to join us on this panel... SUSE was also invited but let us know they were unable to send someone on short notice to Portland for the panel."

One interesting audience question for the panel came from Karsten Wade, a one-time Red Hat senior community architect who left Red Hat in April after 21 years, but said he was "responsible for bringing the CentOS team onboard to Red Hat." Wade argued that CentOS "was always doing a clean rebuild from source RPMS of their own..." So "isn't all of this thunder doing Red Hat's job for them, of trying to get everyone to say, 'This thing is not the equivalent to RHEL.'"

In response Jeremy Alison made a good point. "None of us here are the arbiters of whether it's good enough of a rebuild of Red Hat Linux. The customers are the arbiters." But this led to an audience member asking a very forward-looking question: what are the chances the community could adopt a new (and open) enterprise Linux standard that distributions could follow. AlmaLinux's Vasquez replied, "Chances are real high... I think everyone sees that as the obvious answer. I think that's the obvious next step. I'll leave it at that." And Oracle's Wright added "to the extent that the market asks us to standardize? We're all responsive."

When asked if they'd consider adding features not found in RHEL ("such as high-security gates through reproducible builds") AlmaLinux's Vasquez said "100% -- yeah. One of the things that we're kind of excited about is the opportunities that this opens for us. We had decided we were just going to focus on this north star of 1:1 Red Hat no matter what -- and with that limitation being removed, we have all kinds of options." And CIQ's Alison said "We're working on FIPS certification for an earlier version of Rocky, that Red Hat, I don't believe, FIPS certified. And we're planning to release that."

AlmaLinux's Vasquez emphasized later that "We're just going to build Enterprise Linux. Red Hat has done a great job of establishing a fantastic target for all of us, but they don't own the rights to enterprise Linux. We can make this happen, without forcing an uncomfortable conversation with Red Hat. We can get around this."

And Alison later applied a "Star Wars" quote to Red Hat's predicament. "The more things you try and grab, the more things slip through your fingers." That is, "The more somebody tries to exert control over a codebase, the more the pushback will occur from people who collaborate in that codebase." AlmaLinux's Vasquez also said they're already "in conversations" with independent software vendors about the "flow of support" into non-Red Hat distributions -- though that's always been the case. "Finding ways to reduce the barrier for those independent software vendors to add official support for us is, like, maybe more cumbersome now, but it's the same problem that we've had..."

Early in the discussion Oracle's Jim Wright pointed out that even Red Hat's own web site defines open source code as "designed to be publicly accessible — anyone can see, modify, and distribute the code as they see fit." ("Until now," Wright added pointedly...) There was some mild teasing of Oracle during the 50-minute discussion -- someone asked at one point if they'd re-license their proprietary implementation of ZFS under the GPL. But at the end of the panel, Oracle's Jim Wright still reminded the audience that "If you want to work on open source Linux, we are hiring."

"Having big U.K. meat-eaters cut some of it out of their diet would be like taking 8 million cars off the road," reports the BBC: That's just one of the findings of new research that scientists say gives the most reliable calculation yet of how what we eat impacts our planet.

The Oxford University study is the first to pinpoint the difference high- and low-meat diets have on greenhouse gas emissions, researchers say... [Oxford University] professor Peter Scarborough, who is part of the Livestock Environment And People project surveyed 55,000 people who were divided into big meat-eaters, who ate more than 100g of meat a day, which equates to a big burger, low meat-eaters, whose daily intake was 50g or less, approximately a couple of chipolata sausages, fish-eaters, vegetarians and vegans... The research shows that a big meat-eater's diet produces an average of 10.24 kg of planet-warming greenhouse gasses each day. A low meat-eater produces almost half that at 5.37 kg per day. [Fish diet: 4.74 kg. "Vegetarian" diet: 4.16 kg] And for vegan diets — it's halved again to 2.47 kg a day.

The analysis is the first to look at the detailed impact of diets on other environmental measures all together. These are land use, water use, water pollution and loss of species, usually caused by loss of habitat because of expansion of farming. In all cases high meat-eaters had a significantly higher adverse impact than other groups...

A separate study also published in Nature Food in 2021 concluded that food production was responsible for a third of all global greenhouse gas emissions. And an independent review for the Department for the Environment Food and Rural Affairs (Defra) called for a 30% reduction in meat consumption by 2032 in order to meet the UK's net zero target.
"The meat industry said the analysis overstated the impact of eating meat."
