An anonymous reader quotes a report from Wired: Jazmin Jones knowswhat she did. "If you're online, there's this idea of trolling," Jones, the director behindSeeking Mavis Beacon, said during a recent panel for her new documentary. "For this project, some things we're taking incredibly seriously ... and other things we're trolling. We're trolling this idea of a detective because we're also, like,ACAB." Her trolling, though, was for a good reason. Jones and fellow filmmaker Olivia Mckayla Ross did it in hopes of finding the woman behind Mavis Beacon Teaches Typing. The popular teaching tool was released in 1987 by The Software Toolworks, a video game and software company based in California that produced educational chess, reading, and math games. Mavis, essentially the "mascot" of the game, is a Black woman donned in professional clothes and a slicked-back bun. Though Mavis Beacon was not an actual person, Jones and Ross say that she is one of the first examples of Black representation they witnessed in tech. Seeking Mavis Beacon, which opened in New York City on August 30 and is rolling out to other cities in September, is their attempt to uncover the story behind the face, which appeared on the tool's packaging and later as part of its interface.

The film shows the duo setting up a detective room, conversing over FaceTime, running up to people on the street, and even tracking down a relative connected to the ever-elusive Mavis. But the journey of their search turned up a different question they didn't initially expect: What are the impacts of sexism, racism, privacy, and exploitation in a world where you can present yourself any way you want to? Using shots from computer screens, deep dives through archival footage, and sit-down interviews, the noir-style documentary reveals that Mavis Beacon is actually Renee L'Esperance, a Black model from Haiti who was paid $500 for her likeness with no royalties, despite the program selling millions of copies. [...]

In a world where anyone can create images of folks of any race, gender, or sexual orientation without having to fully compensate the real people who inspired them, Jones and Ross are working to preserve not only the data behind Mavis Beacon but also the humanity behind the software. On the panel, hosted by Black Girls in Media, Ross stated that the film's social media has a form where users of Mavis Beacon can share what the game has meant to them, for archival purposes. "On some level, Olivia and I are trolling ideas of worlds that we never felt safe in or protected by," Jones said during the panel. "And in other ways, we are honoring this legacy of cyber feminism, historians, and care workers that we are very seriously indebted to."

Slashdot covered shrinkwrap licenses on software back in 2000 and 2002. But now ewhac (Slashdot reader #5,844) writes: The user Wraithe on the Mastodon network is reporting that a bottle of Vital Proteins(TM) collagen peptides purchased at Costco came with a shrinkwrap contract. Collagen peptides are often used as an anti-aging nutritional supplement. The top of the Vital Proteins bottle has a pull-to-open seal. Printed on the seal is the following: "Read This: By opening and using this product, you agree to be bound by our Terms and Conditions, fully set forth at vitalproteins.com/tc, which includes a mandatory arbitration agreement. If you do not agree to be bound, please return this product immediately."

So-called "shrinkwrap contracts" have been the subject of controversy and derision for decades since their first widespread appearance in the 1970's, attempting to alter the terms of sale after the fact, impose unethical and onerous restrictions on the purchaser, and absolving the vendor of all liability. Most such contracts appear on items involving copyrighted works (computer software, or any item containing computer software). The alleged "validity" of such contracts supposedly proceeds from the (alleged) need that the item requires a copyright license from the vendor to use (because the right to use/read/listen/view/execute is somehow not concomitant with purchase), and that the shrinkwrap contract furnishes such license.

The application of such a contract to a good where copyright has no scope, however, is something new. The alleged contract itself governs consumers' use of, "the VitalProteins.com website and any other applications, content, products, and services (collectively, the "Service")...," contains the usual we're-not-responsible-for-anything indemnification paragraph, and unilaterally removes your right to seek redress in court of law and imposes binding arbitration involving any disputes that may arise between the consumer and the company. Indeed, the arbitration clause is the first numbered section in the alleged contract.
The same contract has been spotted by numerous others — including someone who posted about it on Reddit two years ago. ("When I opened it, encountered a vacuum seal with the following 'READ THIS: by opening and using this product, you agree to...'") But the same verbiage still appears in online listings today for the product from Albertsons, Walgreens, and CVS.

Shrinkwrap contracts. They're not just for software any more...

An anonymous reader quotes a report from Ars Technica: The Open Source Initiative (OSI) recently unveiled its latest draft definition for "open source AI," aiming to clarify the ambiguous use of the term in the fast-moving field. The move comes as some companies like Meta release trained AI language model weights and code with usage restrictions while using the "open source" label. This has sparked intense debates among free-software advocates about what truly constitutes "open source" in the context of AI. For instance, Meta's Llama 3 model, while freely available, doesn't meet the traditional open source criteria as defined by the OSI for software because it imposes license restrictions on usage due to company size or what type of content is produced with the model. The AI image generator Flux is another "open" model that is not truly open source. Because of this type of ambiguity, we've typically described AI models that include code or weights with restrictions or lack accompanying training data with alternative terms like "open-weights" or "source-available."

To address the issue formally, the OSI -- which is well-known for its advocacy for open software standards -- has assembled a group of about 70 participants, including researchers, lawyers, policymakers, and activists. Representatives from major tech companies like Meta, Google, and Amazon also joined the effort. The group's current draft (version 0.0.9) definition of open source AI emphasizes "four fundamental freedoms" reminiscent of those defining free software: giving users of the AI system permission to use it for any purpose without permission, study how it works, modify it for any purpose, and share with or without modifications. [...] OSI's project timeline indicates that a stable version of the "open source AI" definition is expected to be announced in October at the All Things Open 2024 event in Raleigh, North Carolina.

America's Department of Energy has three R&D labs, according to Wikipedia, one of which is Sandia National Labs. And that New Mexico-based lab has just announced that "A milestone in quantum sensing is drawing closer, promising exquisitely accurate, GPS-free navigation." with research into "a motion sensor so precise it could minimize the nation's reliance on global positioning satellites." Until recently, such a sensor — a thousand times more sensitive than today's navigation-grade devices — would have filled a moving truck. But advancements are dramatically shrinking the size and cost of this technology. For the first time, researchers from Sandia National Laboratories have used silicon photonic microchip components to perform a quantum sensing technique called atom interferometry, an ultra-precise way of measuring acceleration. It is the latest milestone toward developing a kind of quantum compass for navigation when GPS signals are unavailable. The team published its findings and introduced a new high-performance silicon photonic modulator — a device that controls light on a microchip — as the cover story in the journal Science Advances... The new modulator is the centerpiece of a laser system on a microchip. Rugged enough to handle heavy vibrations, it would replace a conventional laser system typically the size of a refrigerator...

Besides size, cost has been a major obstacle to deploying quantum navigation devices. Every atom interferometer needs a laser system, and laser systems need modulators. "Just one full-size single-sideband modulator, a commercially available one, is more than $10,000," said Sandia scientist Jongmin Lee. Miniaturizing bulky, expensive components into silicon photonic chips helps drive down these costs. "We can make hundreds of modulators on a single 8-inch wafer and even more on a 12-inch wafer," Kodigala said. And since they can be manufactured using the same process as virtually all computer chips, "This sophisticated four-channel component, including additional custom features, can be mass-produced at a much lower cost compared to today's commercial alternatives, enabling the production of quantum inertial measurement units at a reduced cost," Lee said.

As the technology gets closer to field deployment, the team is exploring other uses beyond navigation. Researchers are investigating whether it could help locate underground cavities and resources by detecting the tiny changes these make to Earth's gravitational force. They also see potential for the optical components they invented, including the modulator, in LIDAR, quantum computing, and optical communications.

The nonprofit American Radio Relay League — founded in 1914 — has approximately 161,000 members, according to Wikipedia (with over 7,000 members outside the U.S.)

But sometime in early May its systems network was compromised, "by threat actors using information they had purchased on the dark web," the nonprofit announced this week. The attackers accessed the ARRL's on-site systems — as well as most of its cloud-based systems — using "a wide variety of payloads affecting everything from desktops and laptops to Windows-based and Linux-based servers." Despite the wide variety of target configurations, the threat actors seemed to have a payload that would host and execute encryption or deletion of network-based IT assets, as well as launch demands for a ransom payment, for every system... The FBI categorized the attack as "unique" as they had not seen this level of sophistication among the many other attacks, they have experience with.

Within 3 hours a crisis management team had been constructed of ARRL management, an outside vendor with extensive resources and experience in the ransomware recovery space, attorneys experienced with managing the legal aspects of the attack including interfacing with the authorities, and our insurance carrier. The authorities were contacted immediately as was the ARRL President... [R]ansom demands were dramatically weakened by the fact that they did not have access to any compromising data. It was also clear that they believed ARRL had extensive insurance coverage that would cover a multi-million-dollar ransom payment. After days of tense negotiation and brinkmanship, ARRL agreed to pay a $1 million ransom. That payment, along with the cost of restoration, has been largely covered by our insurance policy...

Today, most systems have been restored or are waiting for interfaces to come back online to interconnect them. While we have been in restoration mode, we have also been working to simplify the infrastructure to the extent possible. We anticipate that it may take another month or two to complete restoration under the new infrastructure guidelines and new standards.
ARRL's called the attack "extensive", "sophisticated", "highly coordinated" and "an act of organized crime". And tlhIngan (Slashdot reader #30335) shared this detail from BleepingComputer.

"While the organization has not yet linked the attack to a specific ransomware operation, sources told BleepingComputer that the Embargo ransomware gang was behind the breach."

The Wow! signal, detected on August 15, 1977, was an intense radio transmission that appeared artificial and raised the possibility of extraterrestrial contact. However, recent research suggests it may have been caused by a natural astrophysical event involving a magnetar flare striking a hydrogen cloud. Universe Today reports: New research shows that the Wow! Signal has an entirely natural explanation. The research is "Arecibo Wow! I: An Astrophysical Explanation for the Wow! Signal." The lead author is Abel Mendez from the Planetary Habitability Laboratory at the University of Puerto Rico at Arecibo. It's available at the pre-print server arxiv.org. Arecibo Wow! is a new effort based on an archival study of data from the now-defunct Arecibo Radio Telescope from 2017 to 2020. The observations from Arecibo are similar to those from Big Ear but "are more sensitive, have better temporal resolution, and include polarization measurements," according to the authors. "Our latest observations, made between February and May 2020, have revealed similar narrowband signals near the hydrogen line, though less intense than the original Wow! Signal," said Mendez.

Arecibo detected signals similar to the Wow! signal but with some differences. They're far less intense and come from multiple locations. The authors say these signals are easily explained by an astrophysical phenomenon and that the original Wow! signal is, too. "We hypothesize that the Wow! Signal was caused by sudden brightening from stimulated emission of the hydrogen line due to a strong transient radiation source, such as a magnetar flare or a soft gamma repeater (SGR)," the researchers write. Those events are rare and rely on precise conditions and alignments. They can cause clouds of hydrogen to brighten considerably for seconds or even minutes.

The researchers say that what Big Ear saw in 1977 was the transient brightening of one of several H1 (neutral hydrogen) clouds in the telescope's line of sight. The 1977 signal was similar to what Arecibo saw in many respects. "The only difference between the signals observed in Arecibo and the Wow! Signal is their brightness. It is precisely the similarity between these spectra that suggests a mechanism for the origin of the mysterious signal," the authors write. These signals are rare because the spatial alignment between source, cloud, and observer is rare. The rarity of alignment explains why detections are so rare. The researchers were able to identify the clouds responsible for the signal but not the source. Their results suggest that the source is much more distant than the clouds that produce the hydrogen signal. "Given the detectability of the clouds as demonstrated in our data, this insight could enable precise location of the signal's origin and permit continuous monitoring for subsequent events," the researchers explain.

An anonymous reader quotes a report from Ars Technica: Pong will always hold a special place in the history of gaming as one of the earliest arcade video games. Introduced in 1972, it was a table tennis game featuring very simple graphics and gameplay. In fact, it's simple enough that even non-living materials known as hydrogels can "learn" to play the game by "remembering" previous patterns of electrical stimulation, according to a new paper published in the journal Cell Reports Physical Science. "Our research shows that even very simple materials can exhibit complex, adaptive behaviors typically associated with living systems or sophisticated AI," said co-author Yoshikatsu Hayashi, a biomedical engineer at the University of Reading in the UK. "This opens up exciting possibilities for developing new types of 'smart' materials that can learn and adapt to their environment." [...]

The experimental setup was fairly simple. The researchers hooked up electroactive hydrogels to a simulated virtual environment of a Pong game using a custom-built electrode array. The games would start with the ball traveling in a random direction. The hydrogels tracked the ball's position via electrical stimulation and tracked the paddle's position by measuring the distribution of ions in the hydrogels. As the games progressed, the researchers measured how often the hydrogel managed to hit the ball with the paddle. They found that, over time, the hydrogels' accuracy improved, hitting the ball more frequently for longer rallies. They reached their maximum potential for accuracy in about 20 minutes, compared to 10 minutes for the DishBrain. The authors attribute this to the ion movement essentially mapping out a "memory" of all motion over time, exhibiting what appears to be emergent memory functions within the material itself. Perhaps the next step will be to "teach" the hydrogels how to align the paddles in such a way that the rallies go on indefinitely.

Ars Technica's Dan Goodwin writes: Last Tuesday, loads of Linux users -- many running packages released as early as this year -- started reporting their devices were failing to boot. Instead, they received a cryptic error message that included the phrase: "Something has gone seriously wrong." The cause: an update Microsoft issued as part of its monthly patch release. It was intended to close a 2-year-old vulnerability in GRUB, an open source boot loader used to start up many Linux devices. The vulnerability, with a severity rating of 8.6 out of 10, made it possible for hackers to bypass secure boot, the industry standard for ensuring that devices running Windows or other operating systems don't load malicious firmware or software during the bootup process. CVE-2022-2601 was discovered in 2022, but for unclear reasons, Microsoft patched it only last Tuesday. [...]

With Microsoft maintaining radio silence, those affected by the glitch have been forced to find their own remedies. One option is to access their EFI panel and turn off secure boot. Depending on the security needs of the user, that option may not be acceptable. A better short-term option is to delete the SBAT Microsoft pushed out last Tuesday. This means users will still receive some of the benefits of Secure Boot even if they remain vulnerable to attacks that exploit CVE-2022-2601. The steps for this remedy are outlined here (thanks to manutheeng for the reference).

"A new Mozilla logo appears to be on the way," writes the blog OMG Ubuntu, " marking the company's first major update to its word-mark since 2017." The existing logo, which incorporates the internet protocol "://" and chosen based on feedback from the community, has become synonymous with the non-profit company. But German blogger Sören Hentzschel, an avid watcher of all things Mozilla, recently noticed that a different Mozilla word-mark was accompanying the (unchanged) Firefox logo on Mozilla's 'Nothing Personal' webpage [upper-left]. Some digging uncovered a number of recent code commits readying and referencing a refreshed word-mark and symbol for use in the navigation areas of Mozilla websites, landing pages, and so on...

However, what's most exciting (to a nerd like me) with this new logo is the ASCII symbol at the end. It could be viewed as a flag on a pole. Sort of like Mozilla planting its values in the ground to say "we're here, come join". But it's more likely a nod to the original Mozilla mascot (inherited from its Netscape beginnings), which was a red dinosaur (an interesting logo of itself as it was designed by Shepard Fairey who created other seminal design works, and the skate brand OBEY)...

Between the inclusion on a live webpage, code commits readying new logo for Mozilla websites, and the fact people can buy official Mozilla merchandise emblazoned with the new design, it seems a formal rebrand announcement is fairly imminent...

Long-time Slashdot reader theodp writes: Christie's this week announced the items that will be auctioned in three sales from the Paul G. Allen Collection, including historic computers and artifacts from the late Microsoft co-founder's former Living Computers Museum + Labs in Seattle. They include an Apple-1 from the desk of late Apple co-founder Steve Jobs, estimated at $500,000 to $800,000, to be auctioned as part of a live sale on Sept. 10 at Christie's Rockefeller Center in New York.

Among the lot of "Firsts" from the Paul Allen Collection is a circa-1984 PC's Limited Personal Computer (est. $600-$800), which comes with a manual for the Microsoft-developed IBM DOS. Also being offered is a circa-1975 IMSAI 8080 microcomputer (est. $2,000-$3,000). Both computers ran operating systems that can be traced back to the efforts of Digital Research founder Gary Kildall. Kildall's CP/M was adapted for IMSAI in 1975 and inspired the "CP/M work-alike" Quick And Dirty Operating System (QDOS) that Microsoft purchased in 1981, ported to the new IBM PC as MS-DOS, and licensed to IBM, who in turn offered it as PC-DOS...

Interestingly, not present in the any of the three Christie's Paul G. Allen Collection auctions is Allen's rare unedited copy of Kildall's Computer Connections: People, Places, and Events in the Evolution of the Personal Computer Industry (edited version available at CHM), one of only 20 copies that were originally distributed to family and friends shortly before Kildall's death in 1994. (In the unpublished memoir, Kildall's Seattle Times obit reported, Kildall called DOS "plain and simple theft" of CP/M). Documents released in response to a 2018 Washington Public Records Act request revealed that one of those copies found its way into the hands of Allen in 2017, gifted by University of Washington CS professor Ed Lazowska, who led fundraising campaigns for UW's Paul G. Allen Center for Computer Science & Engineering.

"Last year, a major meta-analysis that re-examined 107 studies over 40 years came to the conclusion that no amount of alcohol improves health," the New York Times reported this June, citing a study co-authored by Tim Stockwell, an epidemiologist at the Canadian Institute for Substance Use Research. Dr. Stockwell (and other scientists he's collaborated with) "are overhauling decades-worth of scientific evidence — and newspaper headlines — that backed the health benefits of alcohol," writes the Telegraph, "or what is known in the scientific community as the J-curve. The J-curve is the theory that, like a capital J, the negative health consequences of drinking dip slightly into positive territory with moderate drinking — as it benefits such things as the heart — before rising sharply back into negative territory the more someone drinks."

But Stockwell's study prompted at least one scientist to accuse Stockwell of "cherry picking" evidence to suit an agenda — while a think-tank executive suggests he's a front for a worldwide temperance lobby: Dr Stockwell denies this. Speaking to The Telegraph, he in turn accused his detractors of being funded by the alcohol lobby and said his links to temperance societies were fleeting. He was the president of the Kettil Bruun Society (a think tank born out of what was the international temperance congresses) [from 2005 to 2007] and he has been reimbursed for addressing temperance movements and admits attending their meetings, but, he says, not as a member...

Former British government scientist Richard Harding, who gave evidence on safe drinking to the House of Commons select committee on science and technology in 2011, told The Telegraph that Dr Stockwell had wrongly taken a correlation to be causal. "Dr Stockwell's research is essentially epidemiology, which is the study of populations," Dr Harding said. "You record people's lifestyle and then see what diseases they get and try to correlate the disease with some aspect of their lifestyle. But it is just a correlation, it's just an association. Epidemiology can never establish causality on its own. And in this particular case, Dr Stockwell selected six studies out of 107 to focus on. You could say he cherry picked them. Really, the important thing is not the epidemiology, it's the effect that alcohol actually has on the body. We know the reasons why the curve is J-shaped; it's because of the protective effect moderate consumption has on heart disease and a number of other diseases."

Dr Stockwell rejects Dr Harding's criticism of his study, telling The Telegraph that Dr Harding "doesn't appear to have read it" and accusing him of being in the pocket of the alcohol industry. "We identified six high-quality studies out of 107 and they didn't find any J-shaped curve," Dr Stockwell said. "In fact, since our recent paper, we've now got genetic studies which are showing there's no benefits of low-level alcohol use. I personally think there might still be small benefits, but the point of our work is that, if there are benefits, they've been exaggerating them."
The article notes that Stockwell's research "has been published in The Lancet, among other esteemed organs," and that "scientists he has collaborated with on research highlighting the dangers of alcohol are in positions of power at major institutions, such as the World Health Organisation."

And honestly, the opposing viewpoint seems to be thinly-sourced. Besides Harding (the former British government scientist), the article cites:

• The head of lifestyle economics at the Institute of Economic Affairs (which Wikipedia describes as "a right-wing, free market think tank")

• An alcohol policy specialist at Brock University in Ontario (who argues rather unconvincingly that "you can't measure when someone didn't hurt themselves because a friend invited them for a drink.")

On the basis of that, the article writes "respected peers say it is far from settled science and have cast doubt on his research". (And that "fellow academics and experts" told The Telegraph "they read the report in disbelief.") Did the Telegraph speak to others who just aren't mentioned in the story? Or are they extrapolating, in that famous British tabloid journalism sort of way?

Mozilla's interim CEO Laura Chambers "says the company is reinvesting in Firefox after letting it languish in recent years," reports Fast Company, "hoping to reestablish the browser as independent alternative to the likes of Google's Chrome and Apple's Safari.

"But some of those investments, which also include forays into generative AI, may further upset the community that's been sticking with Firefox all these years..." Chambers acknowledges that Mozilla lost sight of Firefox in recent years as it chased opportunities outside the browser, such as VPN service and email masking. When she replaced Mitchell Baker as CEO in February, the company scaled back those other efforts and made Firefox a priority again. "Yes, Mozilla is refocusing on Firefox," she says. "Obviously, it's our core product, so it's an important piece of the business for us, but we think it's also really an important part of the internet."

Some of that focus involves adding features that have become table-stakes in other browsers. In June, Mozilla added vertical tab support in Firefox's experimental branch, echoing a feature that Microsoft's Edge browser helped popularize three years ago. It's also working on tab grouping features and an easier way to switch between user profiles. Mozilla is even revisiting the concept of web apps, in which users can install websites as freestanding desktop applications. Mozilla abandoned work on Progressive Web Apps in Firefox a few years ago to the dismay of many power users, but now it's talking with community members about a potential path forward.

"We haven't always prioritized those features as highly as we should have," Chambers says. "That's been a real shift that's been very felt in the community, that the things they're asking for . . . are really being prioritized and brought to life."
Firefox was criticized for testing a more private alternative to tracking cookies which could make summaries of aggregated data available to advertisers. (Though it was only tested on a few sites, "Privacy-Preserving Attribution" was enabled by default.) But EFF staff technologist Lena Cohen tells Fast Company that approach was "much more privacy-preserving" than Google's proposal for a "Privacy Sandbox." And according to the article, "Mozilla's system only measures the success rate of ads — it doesn't help companies target those ads in the first place — and it's less susceptible to abuse due to limits on how much data is stored and which parties are allowed to access it." In June, Mozilla also announced its acquisition of Anonym, a startup led by former Meta executives that has its own privacy-focused ad measurement system. While Mozilla has no plans to integrate Anonym's tech in Firefox, the move led to even more anxiety about the kind of company Mozilla was becoming. The tension around Firefox stems in part from Mozilla's precarious financial position, which is heavily dependent on royalty payments from Google. In 2022, nearly 86% of Mozilla's revenue came from Google, which paid $510 million to be Firefox's default search engine. Its attempts to diversify, through VPN service and other subscriptions, haven't gained much traction.

Chambers says that becoming less dependent on Google is "absolutely a priority," and acknowledges that building an ad-tech business is one way of doing that. Mozilla is hoping that emerging privacy regulations and wider adoption of anti-tracking tools in web browsers will increase demand for services like Anonym and for systems like Firefox's privacy-preserving ad measurements. Other revenue-generating ideas are forthcoming. Chambers says Mozilla plans to launch new products outside of Firefox under a "design sprint" model, aimed at quickly figuring out what works and what doesn't. It's also making forays into generative AI in Firefox, starting with a chatbot sidebar in the browser's experimental branch.
Chambers "says to expect a bigger marketing push for Firefox in the United States soon, echoing a 'Challenge the default' ad campaign that was successful in Germany last summer. Mozilla's nonprofit ownership structure, and the idea that it's not beholden to corporate interests, figures heavily into those plans."

An anonymous reader quotes a report from Ars Technica: Inertial confinement fusion is one method for generating energy through nuclear fusion, albeit one plagued by all manner of scientific challenges (although progress is being made). Researchers at LeHigh University are attempting to overcome one specific bugbear with this approach by conducting experiments with mayonnaise placed in a rotating figure-eight contraption. They described their most recent findings in a new paper published in the journal Physical Review E with an eye toward increasing energy yields from fusion.

The work builds on prior research in the LeHigh laboratory of mechanical engineer Arindam Banerjee, who focuses on investigating the dynamics of fluids and other materials in response to extremely high acceleration and centrifugal force. In this case, his team was exploring what's known as the "instability threshold" of elastic/plastic materials. Scientists have debated whether this comes about because of initial conditions, or whether it's the result of "more local catastrophic processes," according to Banerjee. The question is relevant to a variety of fields, including geophysics, astrophysics, explosive welding, and yes, inertial confinement fusion. [...]

The problem is that hydrodynamic instabilities tend to form in the plasma state -- Banerjee likens it to "two materials [that] penetrate one another like fingers" in the presence of gravity or any accelerating field -- which in turn reduces energy yields. The technical term is a Rayleigh-Taylor instability, which occurs between two materials of different densities, where the density and pressure gradients move in opposite directions. Mayonnaise turns out to be an excellent analog for investigating this instability in accelerated solids, with no need for a lab setup with high temperature and pressure conditions, because it's a non-Newtonian fluid. "We use mayonnaise because it behaves like a solid, but when subjected to a pressure gradient, it starts to flow," said Banerjee. "As with a traditional molten metal, if you put a stress on mayonnaise, it will start to deform, but if you remove the stress, it goes back to its original shape. So there's an elastic phase followed by a stable plastic phase. The next phase is when it starts flowing, and that's where the instability kicks in." In 2019, Banerjee's team conducted experiments that "involved pouring Hellman's Real Mayonnaise [...] into a Plexiglass container and then creating wavelike perturbations in the mayo," writes Ars' Jennifer Ouellette. "One experiment involved placing the container on a rotating wheel in the shape of a figure eight and tracking the material with a high-speed camera, using an image processing algorithm to analyze the footage. Their results supported the claim that the instability threshold is dependent on initial conditions, namely amplitude and wavelength."

"This latest paper sheds more light on the structural integrity of fusion capsules used in inertial confinement fusion, taking a closer look at the material properties, the amplitude and wavelength conditions, and the acceleration rate of such materials as they hit the Rayleigh-Taylor instability threshold."

An anonymous reader quotes a report from TorrentFreak: In Brazil, there was a [...] unbelievable display of public piracy last week that went on to make national headlines. The mayor of the municipality Acopiara, in the north-east of the country, invited citizens of the small town Trussu to join a screening of the blockbuster "Inside Out 2" at the local town square. With little more than a thousand inhabitants, many of whom have limited means, this appeared to be a kind gesture. The mayor, Anthony Almeida Neto, could use some positive marks too; he was removed from office three times on suspicion of being involved in corruption schemes, and was most recently reinstated in March. The mayor officially announced the public screening of 'Inside Out 2' via Instagram and Facebook, inviting people to join him. That worked well as a sizable crowd showed up, allowing the controversial mayor to proudly boast the event's popularity in public through his social media channels.

Taking place in an outside theater created just for this occasion, the screening was a unique opportunity for the small town's residents. There are no official movie theaters nearby, so locals would normally have to travel for several hours to see a film that's still in cinemas. Thanks to the mayor, people could see 'Inside Out 2' in their hometown instead. The mayor was pleased with the turnout too and proudly broadcasted it through a livestream on Instagram. Amidst all this joy, however, people started to notice a watermark on the film that was clearly associated with piracy. In addition, it was apparent that the copy had been sourced from pirate streaming site, Obaflix. All signs indicate that the public event wasn't authorized or licensed. Instead, it appeared to be an improvised screening of a low-quality TS release of the film, which is widely available through pirate sites. When this 'revelation' was picked up in the Brazilian press, mayor Anthony Almeida was quick to respond with assurances that he only had honest intentions.

iPhone and Apple Watch users in California will soon be able to add their digital ID and driver's license to the Wallet app, as revealed by new landing pages on the state DMV website. This feature follows a slow rollout since its announcement, with only five states currently supporting it. MacRumors reports: "Now you can add your California driver's license or state ID to Apple Wallet on iPhone and Apple Watch so you can present it easily and securely in person and in app," reads the landing page, which contains broken links and placeholder images, and is still missing a proper website security certificate. The webpages were discovered on Sunday by Jimmy Obomsawin, after someone added a link to the landing pages in an Apple Wallet Wikipedia entry last Wednesday.

Somewhere in America's Defense Department, the DARPA R&D agency is running a two-year contest to write an AI-powered program "that can scan millions of lines of open-source code, identify security flaws and fix them, all without human intervention," reports the Washington Post. [Alternate URL here.]

But as they see it, "The contest is one of the clearest signs to date that the government sees flaws in open-source software as one of the country's biggest security risks, and considers artificial intelligence vital to addressing it." Free open-source programs, such as the Linux operating system, help run everything from websites to power stations. The code isn't inherently worse than what's in proprietary programs from companies like Microsoft and Oracle, but there aren't enough skilled engineers tasked with testing it. As a result, poorly maintained free code has been at the root of some of the most expensive cybersecurity breaches of all time, including the 2017 Equifax disaster that exposed the personal information of half of all Americans. The incident, which led to the largest-ever data breach settlement, cost the company more than $1 billion in improvements and penalties.

If people can't keep up with all the code being woven into every industrial sector, DARPA hopes machines can. "The goal is having an end-to-end 'cyber reasoning system' that leverages large language models to find vulnerabilities, prove that they are vulnerabilities, and patch them," explained one of the advising professors, Arizona State's Yan Shoshitaishvili.... Some large open-source projects are run by near-Wikipedia-size armies of volunteers and are generally in good shape. Some have maintainers who are given grants by big corporate users that turn it into a job. And then there is everything else, including programs written as homework assignments by authors who barely remember them.

"Open source has always been 'Use at your own risk,'" said Brian Behlendorf, who started the Open Source Security Foundation after decades of maintaining a pioneering free server software, Apache, and other projects at the Apache Software Foundation. "It's not free as in speech, or even free as in beer," he said. "It's free as in puppy, and it needs care and feeding."
40 teams entered the contest, according to the article — and seven received $1 million in funding to continue on to the next round, with the finalists to be announced at this year's Def Con, according to the article.

"Under the terms of the DARPA contest, all finalists must release their programs as open source," the article points out, "so that software vendors and consumers will be able to run them."

As Comic-Con hits San Diego, "part of the big news in 2024 is that the con won't have a corresponding virtual or online event this year," according to Polygon, "for the first time since 2019."

But there's still some big scifi media news, according to CNET's Comic-Con coverage: Disney revealed a new Doctor Who addition to the franchise that will jump back to the 1970s with the Sea Devils, an ancient group of beings who arise from the sea. Made in partnership with the BBC, the series... will air on Disney Plus, where fans can currently stream season 14 of Doctor Who starring Ncuti Gatwa.
And there's also an upcoming Doctor Who Christmas special.

Meanwhile, Saturday night, USA Today ran a special article with late-breaking announcements about Marvel's Cinematic Universe: Marvel has already won Comic-Con, with a raucous screening of "Deadpool & Wolverine" followed by a high-tech drone show, and the box office, with the new movie on track to have one of the best openings of all time... Robert Downey Jr. returns to the MCU as Doctor Doom in Avengers: Doomsday. Kevin Feige says the Fantastic Four will be in the next two Avengers movies... And here comes the Fantastic Four [movie] a year from now. It starts filming Tuesday in the UK...
The article says Marvel's Fantastic Four presentation included "a Fantasti-Car that hovers across the stage — and that castmembers also appeared from the upcoming Thunderbolts* movie.

More geeky news:

• Amazon Prime showed a new four-minute trailer with clips from season two of its J.R.R. Tolkein prequel, "The Rings of Power". (And there was also a three-minute blooper reel for Season 4 of Prime's superhero-themed series, "The Boys".)

• Paramount+ showed a trailer for the Star Trek universe's first streaming movie, Section 31. There was also a trailer for season 5 of the animated comedy Star Trek: Lower Decks — plus a particularly strange clip from the fourth season of Star Trek: Strange New Worlds.

• Keanu Reeves accepted the Inkpot award for his contribution to the world of film and comics — partly because since 2021 Reeves has been co-authoring a Kickstarter-funded comic book called BRZRKR. (Netflix plans to adapt it into a movie.)

• Next February will see the release of Captain America: Brave New World, in which the Incredible Hulk may get some competition from Harrison Ford, who's been cast as the Red Hulk.

But things got a little too real Friday when a fire at a nearby steakhouse forced the evacuation of the immersive "Penguin Lounge" — which was promoting Max's new prequel series to 2022's movie The Batman.

Speaking at the Bitcoin Conference in Nashville, Republican presidential nominee Donald Trump made a number of cryptocurrency-related pledges:

• Trump promised that if elected, he'd commute the sentence of Silk Road creator Ross Ulbricht to a sentence of time served. "It's enough."

• Trump promised to change the top personnel at America's Securities and Exchange Commission. "On Day One, I will fire Gary Gensler and appoint a new SEC chairman," Trump told the crowd, drawing a long round of applause. ("I didn't know he was that unpopular," Trump joked — then repeated his promise to appoint "a new SEC chairman who believes America should build the future, not block the future, which is what they're doing.")

• Trump also promised that "As president, I will immediately shut down Operation Chokepoint 2.0." (For context, Operation Chokepoint was an Obama-era program — ended during Trump's presidency — to scrutinize bank lending to "high-risk" merchants, mostly predatory "payday" lenders. Concerns were raised that bank regulators were pressuring banks to cut off certain businesses, and while there is no official "Choke Point 2.0," the phrase has been used colloquially to describe the possibility of bank regulators pressuring specific industries like cryptocurrency.)

• Trump also announced he'd oppose a central bank digital currency — although his wording was a little idiosyncratic. "Next I will immediately order the Treasury Department and other federal agencies to cease and desist all steps necessary — because, you know, there's a thing going on in your industry. They want to move the creation of a central bank digital currency. It's over, forget it." [Audience boos CBDC's ] "CBDC — there will never be a CBDC while I'm president of the United States." (In fact a 2023 statement from America's Federal Reserve about CBDC's stresses that "no decisions have been made at this time" and that the Federal Reserve would only proceed with a CBDC after passage of an authorizing law.)

• Trump also told the audience that "We will create a framework to enable the safe and responsible expansion of staple — stablecoins," then teased the crypto-friendly audience by asking playfully "Do you know what a stablecoin is? Does anybody know — please raise your hand." Trump promised the move would "allow us to extend the dominance of the U.S. dollar to new frontiers all around the world," and that "there will be billions and billions of people brought into the crypto economy and storing their savings in bitcoin."

• Toward the end Trump said that if elected, he would direct the government not to sell any of its currently-held bitcoin, keeping it instead as the core of a "strategic national bitcoin stockpile."
  
  "As you know, most of the bitcoin currently held by the U.S. government was obtained through law enforcement action — you know that, they took it from you. 'Let's take that guy's life, let's take his family, his house, his bitcoin — we'll turn it into bitcoin.' It's been taken away from you because that's where we're going now. That's where this country is going. It's a facist regime."

In a speech which lasted for over an hour, the 78-year-old former president also criticized his political opponents, touching on topics like inflation, immigration, and his promise to "drill, baby, drill."

But Trump closed by thanking the 3,000 attendees, telling them to "have a good time with your bitcoin, and your crypto and everything else that you're playing with. And we're going to make that one of the greatest industries on earth."

Rosemary Fowler, a pioneering physicist who discovered the kaon particle during her doctoral research in 1948, has been awarded an honorary doctorate from the University of Bristol -- 75 years after she left her PhD to raise a family. The Guardian reports: Rosemary Fowler, 98, discovered the kaon particle during her doctoral research under Cecil Powell at the University of Bristol in 1948, which contributed to his Nobel prize for physics in 1950. Fowler's discovery helped lead to a revolution in the theory of particle physics, and it continues to be proven correct -- predicting particles such as the Higgs boson, discovered at Cern in Geneva, Switzerland. But she left university without completing her PhD to marry fellow physicist Peter Fowler in 1949, a decision she later described as pragmatic after she went on to have three children in a time of postwar food rationing.

At 22, Fowler spotted something when viewing unusual particle tracks -- a particle that decayed into three pions, a type of subatomic particle. She said: "I knew at once that it was new and would be very important. We were seeing things that hadn't been seen before -- that's what research in particle physics was. It was very exciting." The track, later labelled K, was evidence of an unknown particle, now known as the kaon or K meson. The K track was the mirror image of a particle seen before by colleagues in Manchester, but their track decayed into two pions, not three. Trying to understand how these images were the same, yet behaved differently, helped lead to a revolution in the theory of particle physics. The year after the discovery, Fowler left university having published her discovery in three academic papers.

Re-visiting the Napster era, Stephen Witt's book How Music Got Free has been adapted into a two-part documentary on Paramount+. But the documentary's director believes "The real innovative minds here were a bunch of rogue teenagers and a guy working a blue-collar factory job in the tiny town of Shelby, North Carolina," according to this article in the Guardian: By day, [Glover] worked at Universal Music's CD manufacturing plant in North Carolina, from which he smuggled out hot albums by stars like Mary J Blige and 50 Cent before they were even released. For the documentary, Glover spoke openly, and largely without regret, as did others who worked at that plant who did their own share of stealing. Part of their incentive was class revenge: while they were paid piddling wages by the hour, the industry used the products they manufactured to mint millions. To maximize profits on his end, Glover set up a subscription service to let those in his circle know what CDs and movies were coming. "He was doing what Netflix would later do," Stapleton said...

In the meantime, the record companies and their lobbying arm, the RIAA, focused their wrath on the most public face of file-sharing: Napster. In truth, all Fanning's company did was make more accessible the work the pirates innovated and first distributed... For its part, the music industry reacted in the worst way possible, PR-wise. They sued the kids who made up their strongest fanbase. "One of the key lessons we learned from this era is that you can't sue your way out of a situation like this," Witt said. "You have to build a new technology that supersedes what the pirates did."

Eventually, that's what happened, though the first attempts in that direction made things worse than ever for the labels and stars. When Apple first created the iPod in 2001, there wasn't yet an Apple store where listeners could purchase music legally. "It was just a place to put your stolen MP3s," said Witt. Labels couldn't sue Apple because of a ruling dictating that the manufacturer of a device couldn't be held responsible for piracy enacted by its users. While Steve Jobs later modified his approach, creating a way for fans to buy individual songs for the iPod, "that did more damage to the industry than anything", Witt said. "Whereas, before they could sell a $15 CD to fans who really just wanted one song, now those fans could get that song for just a dollar...."

Eventually, the collective efforts of the streaming companies returned the music industry to massive profitability, though often at the expense of its artists, who often receive a meager slice of the proceeds.... Things ended less favorably for the pirates, some of whom now have criminal records. Likewise, Glover served a short prison sentence though, today, he is chief maintenance technician at the Ryder Truck manufacturing plant in his home town.
A Forbes senior contributor (and director Alexandria Stapleton) believe that for the younger generation it may be "their first introduction to why the music industry is the way that they're used to."

And Stapleton says their sympathies are with those factory workers. Stapleton: They were completely underpaid. They were making literally nothing. It's important for people to understand that while the industry was charging $20 for a CD, it cost like 20 cents to make. That's a big profit margin. And to have a factory that was paying barely enough for people to put food on the table, I think there's something wrong with that...

Witt: It's amazing to think about what they were really doing, which was essentially filling the technological vacuum that the record industry was refusing to fill, right? The record industry was not building out the successor technology to the compact disc because the compact disc was just too profitable for them. Instead, a bunch of random teenagers built the next generation of technology for them, and yeah, it caused a lot of damage. But I don't think that teenagers were necessarily trying to hurt anyone... They weren't malicious. They just were fascinated by how this stuff worked. And of course, they were also completely entranced by the celebrity of the musicians themselves.
In the interview Witt adds that a lot of those teenagers "were really kind of traumatized by their experience with the FBI I would say, and they wanted to get that story out there."

The documentary was produced by LeBron James and Eminem, "who rode the tail end of the CD boom to stratospheric heights," remembers a Fast Company opinion columnist. (And 25 years later, that columnist has gone back to listening to vinyl records, which "reignited for me a long-missing air of full engagement... Technology marches forward, except when it occasionally lurches backward...")
