An anonymous reader quotes a report from The Guardian: Ultra-processed foods (UPFs) are displacing healthy diets "all over the world" despite growing evidence of the risks they pose and should be sold with tobacco-style warnings, according to the nutritional scientist who first coined the term. Prof Carlos Monteiro of the University of Sao Paulo will highlight the increasing danger UPFs present to children and adults at the International Congress on Obesity this week. "UPFs are increasing their share in and domination of global diets, despite the risk they represent to health in terms of increasing the risk of multiple chronic diseases," Monteiro told the Guardian ahead of the conference in Sao Paulo. "UPFs are displacing healthier, less processed foods all over the world, and also causing a deterioration in diet quality due to their several harmful attributes. Together, these foods are driving the pandemic of obesity and other diet-related chronic diseases, such as diabetes."

Monteiro and his colleagues first used the phrase UPF 15 years ago when designing the food classification system "Nova." This assesses not only nutritional content but also the processes food undergoes before it is consumed. The system places food and drink into four groups: minimally processed food, processed culinary ingredients, processed food and ultra-processed food. Monteiro told the Guardian he was now so concerned about the impact UPF was having on human health that studies and reviews were no longer sufficient to warn the public of the health hazards. "Public health campaigns are needed like those against tobacco to curb the dangers of UPFs," he told the Guardian in an email. "Such campaigns would include the health dangers of consumption of UPFs. Advertisements for UPFs should also be banned or heavily restricted, and front-of-pack warnings should be introduced similar to those used for cigarette packs."

He will tell delegates: "Sales of UPFs in schools and health facilities should be banned, and there should be heavy taxation of UPFs, with the revenue generated used to subsidize fresh foods." Monteiro will tell the conference that food giants marketing UPFs know that, in order to be competitive, their products must be more convenient, more affordable and tastier than freshly prepared meals. "To maximize profits, these UPFs must have lower cost of production and be overconsumed," he said. He will also draw parallels between UPF and tobacco companies. "Both tobacco and UPFs cause numerous serious illnesses and premature mortality; both are produced by transnational corporations that invest the enormous profits they obtain with their attractive/addictive products in aggressive marketing strategies, and in lobbying against regulation; and both are pathogenic (dangerous) by design, so reformulation is not a solution."

Speaking of Microsoft, the House Homeland Security committee is grilling Microsoft President Brad Smith Thursday about the software giant's plans to improve its security after a series of devastating hacks reached into federal officials' email accounts, challenging the company's fitness as a dominant government contractor. Washington Post adds:The questioning followed a withering report on one of those breaches, where the federal Cyber Safety Review Board found the event was made possible by a "cascade of avoidable errors" and a security culture "that requires an overhaul." In that hack, suspected agents of China's Ministry of State Security last year created digital keys using a tool that allowed them to pose as any existing Microsoft customer. Using the tool, they impersonated 22 organizations, including the U.S. Departments of State and Commerce, and rifled through Commerce Secretary Gina Raimondo's email among others.

The event triggered the sharpest criticism in decades of the stalwart federal vendor, and has prompted rival companies and some authorities to push for less government reliance on its technology. Two senators wrote to the Pentagon last month, asking why the agency plans to improve nonclassified Defense Department tech security with more expensive Microsoft licenses instead of with alternative vendors. "Cybersecurity should be a core attribute of software, not a premium feature that companies upsell to deep-pocketed government and corporate customers," Sens. Eric Schmitt (R-Mo.) and Ron Wyden (D-Ore.) wrote. "Through its buying power, DOD's strategies and standards have the power to shape corporate strategies that result in more resilient cybersecurity services." Any serious shift in executive branch spending would take years, but Department of Homeland Security leaders say plans are in motion to add security guarantees and requirements to more government purchases -- an idea touted in the Cyber Safety Review Board's Microsoft report.

America's Federal Trade Commission and 17 states filed an antitrust suit against Amazon in September. This week Amazon responded in court about its usage of Signal's "disappearing messages" feature.

Long-time Slashdot reader theodp shares GeekWire's report: At a company known for putting its most important ideas and strategies into comprehensive six-page memos, quick messages between executives aren't the place for meaningful business discussions. That's one of the points made by Amazon in its response Monday to the Federal Trade Commission's allegations about executives' use of the Signal encrypted communications app, known for its "disappearing messages" feature. "For these individuals, just like other short-form messaging, Signal was not a means to send 'structured, narrative text'; it was a way to get someone's attention or have quick exchanges on sensitive topics like public relations or human resources," the company says as part of its response, filed Monday in U.S. District Court in Seattle. Of course, for regulators investigating the company's business practices, these offhanded private comments between Amazon executives could be more revealing than carefully crafted memos meant for wider internal distribution. But in its filing this week, Amazon says there is no evidence that relevant messages have been lost, or that Signal was used to conceal communications that would have been responsive to the FTC's discovery requests. The company says "the equally logical explanation — made more compelling by the available evidence — is that such messages never existed."

In an April 25 motion, the FTC argued that the absence of Signal messages from Amazon discussing substantive business issues relevant to the case was a strong indication that such messages had disappeared. "Amazon executives deleted many Signal messages during Plaintiffs' pre-Complaint investigation, and Amazon did not instruct its employees to preserve Signal messages until over fifteen months after Amazon knew that Plaintiffs' investigation was underway," the FTC wrote in its motion. "It is highly likely that relevant information has been destroyed as a result of Amazon's actions and inactions...."

Amazon's filing quotes the company's founder, Jeff Bezos, saying in a deposition in the case that "[t]o discuss anything in text messaging or Signal messaging or anything like that of any substance would be akin to business malpractice. It's just too short of a messaging format...." The company's filing traces the initial use of Signal by executives back to the suspected hacking of Bezos' phone in 2018, which prompted the Amazon founder to seek ways to send messages more securely.

The thinktank InfluenceMap produces "data-driven analysis on how business and finance are impacting the climate crisis." Their web site says their newest report documents "How automaker lobbying threatens the global transition to electric vehicles." This report analyses the climate policy engagement strategies of fifteen of the largest global automakers in seven key regions (Australia, EU, Japan, India, South Korea, UK, US). It shows how even in countries where major climate legislation has recently passed, such as the US and Australia, the ambition of these policies has been weakened due to industry pressure. All fifteen automakers, except Tesla, have actively advocated against at least one policy promoting electric vehicles. Ten of the fifteen showed a particularly high intensity of negative engagement and scored a final grade of D or D+ by InfluenceMap's methodology. Toyota is the lowest-scoring company in this analysis, driving opposition to climate regulations promoting battery electric vehicles in multiple regions, including the US, Australia and UK. Of all automakers analyzed, only Tesla (scoring B) is found to have positive climate advocacy aligned with science-based policy.
CleanTechnica writes that Toyota "led on hybrid vehicles (and still does), so it's actually not surprising that it has been opposed to the next stage of climate-cutting auto evolution — it's clinging on to its lead rather than continuing to innovate for a new era."

More from InfluenceMap: Only three of fifteen companies — Tesla, Mercedes Benz and BMW — are forecast to produce enough electric vehicles by 2030 to meet the International Energy Agency's updated 1.5 degreesC pathway of 66% electric vehicle (battery electric, fuel cell and plug-in hybrids) sales according to InfluenceMap's independent analysis of industry-standard data from February 2024. Current industry forecasts analyzed for this report show automaker production will reach only 53% electric vehicles in 2030. Transport is the third-largest source of greenhouse gas emissions globally, and road transport is failing to decarbonize at anywhere near the rate of many other industries. InfluenceMap's report also finds that Japanese automakers are the least prepared for an electric vehicle transition and are engaging the hardest against it.
"InfluenceMap highlights that these anti-EV efforts in the industry are often coming from industry associations rather than coming directly from automakers, shielding them a bit from inevitable public backlash," writes CleanTechnica.

"Every automaker included in the study except Tesla remains a member of at least two of these groups," InfluenceMap reports, "with most automakers a member of at least five."

Later this month, Comcast will launch a three-way bundle with Peacock, Netflix and Apple TV+. It will "come at a vastly reduced price to anything in the market today," said. Comcast chief Brian Roberts. Variety reports: The goal is to "add value to consumers" and at the same time "take some of the dollars out of" other companies' streaming businesses, he added, while reinforcing Comcast's broadband service offerings. Comcast's impending launch of the StreamSaver bundle come as other media companies have been assembling similar offerings. [...] Like the other streaming bundling strategies, Comcast's forthcoming Peacock, Netflix and Apple TV+ package is an effort to reduce cancelation rates (aka "churn") and provide a more efficient means of subscriber acquisition -- coming as the traditional cable TV business continues to deteriorate. Last week, Disney and Warner Bros. Discovery announced a three-way bundle comprising of Max, Disney+ and Hulu.

Science Alert reports that a team of researchers found "that changes in glucose metabolism could help cancer grow by temporarily disabling a gene that protects us from tumors called BRCA2." The team first examined people who inherited one faulty copy of BRCA2. They found that cells from these people were more sensitive to methylglyoxal (MGO), which is produced when cells break down glucose for energy in the process of glycolysis. Glycolysis generates over 90 percent of the MGO in cells, which a pair of enzymes typically keep to minimal levels. In the event they can't keep up, high MGO levels can lead to the formation of harmful compounds that damage DNA and proteins. In conditions like diabetes, where MGO levels are elevated due to high blood sugar, these harmful compounds contribute to disease complications.

The researchers discovered that MGO can temporarily disable the tumor-suppressing functions of the BRCA2 protein, resulting in mutations linked to cancer development...

As the BRCA2 allele isn't permanently inactivated, functional forms of the protein it produces can later return to normal levels. But cells repeatedly exposed to MGO may continue to accumulate cancer-causing mutations whenever existing BRCA2 protein production fails. Overall, this suggests that changes in glucose metabolism can disrupt BRCA2 function via MGO, contributing to the development and progression of cancer...

This new information may lead to strategies for cancer prevention or early detection. "Methylglyoxal can be easily detected by a blood test for HbA1C, which could potentially be used as a marker," Venkitaraman says. "Furthermore, high methylglyoxal levels can usually be controlled with medicines and a good diet, creating avenues for proactive measures against the initiation of cancer."
Their research has been published in Cell.

In 2016, an online "swarm intelligence" platform generated a correct prediction for the Kentucky Derby — naming all four top finishers, in order. (But the next year their predictions weren't even close, with TechRepublic suggesting 2016's race had an unusual cluster of just a few top racehorses.)

So this year Decrypt.co tried crafting their own system "that can be called up when the next Kentucky Derby draws near. There are a variety of ways to enlist artificial intelligence in horse racing. You could process reams of data based on your own methodology, trust a third-party pre-trained model, or even build a bespoke solution from the ground up. We decided to build a GPT we named HorseGPT to crunch the numbers and make the picks for us...

We carefully curated prompts to instill HorseGPT with expertise in data science specific to horse racing: how weather affects times, the role of jockeys and riding styles, the importance of post positions, and so on. We then fed it a mix of research papers and blogs covering the theoretical aspects of wagering, and layered on practical knowledge: how to read racing forms, what the statistics mean, which factors are most predictive, expert betting strategies, and more. Finally, we gave HorseGPT a wealth of historical Kentucky Derby data, arming it with the raw information needed to put its freshly imparted skills to use.

We unleashed HorseGPT on official racing forms for this year's Derby. We asked HorseGPT to carefully analyze each race's form, identify the top contenders, and recommend wager types and strategies based on deep background knowledge derived from race statistics.
So how did it do? HorseGPT picked two horses to win — both of which failed to do so. (Sierra Leone did finish second — in a rare three-way photo finish. But Fierceness finished... 15th.) It also recommended the same two horses if you were trying to pick the top two finishers in the correct order — a losing bet, since, again, Fierceness finished 15th.

But even worse, HorseGPT recommended betting on Just a Touch to finish in either first or second place. When the race was over, that horse finished dead last. (And when asked to pick the top three finishers in correct order, HorseGPT stuck with its choices for the top two — which finished #2 and #15 — and, again, Just a Touch, who came in last.)

When Google Gemini was asked to pick the winner by The Athletic, it first chose Catching Freedom (who finished 4th). But it then gave an entirely different answer when asked to predict the winner "with an Italian accent."

"The winner of the Kentucky Derby will be... Just a Touch! Si, that's-a right, the underdog! There will be much-a celebrating in the piazzas, thatta-a I guarantee!"
Again, Just a Touch came in last.

Decrypt noticed the same thing. "Interestingly enough, our HorseGPT AI agent and the other out-of-the-box chatbots seemed to agree with each other," the site notes, adding that HorseGPT also seemed to agree "with many expert analysts cited by the official Kentucky Derby website."

But there was one glimmer of insight into the 20-horse race. When asked to choose the top four finishers in order, HorseGPT repeated those same losing picks — which finished #2, #15, and #20. But then it added two more underdogs for fourth place finishers, "based on their potential to outperform expectations under muddy conditions." One of those two horses — Domestic Product — finished in 13th place.

But the other of the two horses was Mystik Dan — who came in first.

Mystik Dan appeared in only one of the six "Top 10 Finishers" lists (created by humans) at the official Kentucky Derby site... in the #10 position.

An anonymous reader shared this report from the blog Bitcoinist: Jack Dorsey's financial services and digital payments company, Block Inc., announced it will begin investing 10% of its monthly Bitcoin-related gross profits into BTC purchases. This announcement was made following the release of Block's first-quarter earnings for 2024, which demonstrated substantial profits from its Bitcoin operations.

Block reported Bitcoin-related gross profits amounting to $80 million in the first quarter alone. If this trend continues, the implementation of the new dollar cost averaging (DCA) program could see the company investing approximately $24 million in Bitcoin within one year... Dorsey also shared a detailed document [PDF] titled "Bitcoin Blueprint For Corporate Balance Sheets," which serves as a comprehensive guide for other corporations interested in integrating BTC into their financial strategies.

According to the document, Block, formerly known as Square, began its substantial acquisitions in October 2020, purchasing 4,709 BTC at an aggregate price of $50 million. The company later bought an additional 3,318 BTC in February 2021 for $170 million. As of March 31, 2024, Block holds approximately 8,038 BTC, representing about 9% of its total cash and marketable securities.

Jess Weatherbed reports via The Verge: Swedish gaming conglomerate Embracer Group announced plans on Monday to split itself into three distinct games and entertainment companies: Asmodee Group, Coffee Stain & Friends, and Middle-earth Enterprises & Friends. These will be separate, publicly listed companies, according to Embracer, which says the move will allow "each entity to better focus on their respective core strategies and offer more differentiated and distinct equity stories for existing and new shareholders." [...]

The three new companies will be broken down as follows:

- Middle-earth Enterprises & Friends: This company, which will be renamed from Embracer Group, is described as a "creative powerhouse in AAA game development and publishing" that will retain ownership of the Dead Island, Killing Floor, Kingdom Come Deliverance, Tomb Raider, and The Lord of the Rings IPs.
- Asmodee Group: a new arm dedicated to publishing and distributing tabletop games. The existing catalog includes established titles like Ticket to Ride, 7 Wonders, Azul, CATAN, Dobble, and Exploding Kittens. Asmodee is also developing licensed tabletop games based on The Lord of the Rings, Marvel, Game of Thrones, and Star Wars franchises. Embracer anticipates the spinoff and share listings will take place "within 12 months."
- Coffee Stain & Friends: described as a "diverse gaming entity" that will focus on indie, mid-market, and free-to-play games. Properties sitting under this new company include Deep Rock Galactic, Goat Simulator, Satisfactory, Wreckfest, Teardown, and Valheim. The share listings are projected to become available in 2025.

Korean newspaper KED Global: Executives at all Samsung Group units will work six days a week from as early as this week in a shift to emergency mode. The move comes as the won's sharp depreciation, rising oil prices and high borrowing costs aggravate business uncertainties after some of the group's mainstay businesses delivered poorer-than-expected results in 2023. The executives of Samsung Electronics Co., including those in the manufacturing and sales divisions, will work either on Saturday or Sunday following the regular five-day work week, according to Samsung Group officials.

They will review their business strategies and may modify them to adapt to the changing business environment amid mounting gepolitical risks from the prolonged war between Russia and Ukraine and escalating tensions in the Middle East. "Considering that performance of our major units, including Samsung Electronics Co., fell short of expectations in 2023, we are introducing the six-day work week for executives to inject a sense of crisis and make all-out efforts to overcome it," said a Samsung Group company executive.

Top management at Samsing Display Co., Samsung Electro-Mechanics Co. and Samsung SDS Co. will adopt the six-day work week as early as this week. Samsung Life Insurance Co. and other financial services firms under the Samsung Group will likely join them soon. Executives of Samsung C&T Corp., Samsung Heavy Industries Co. and Samsung E&A Co. have already been voluntarily working six days a week since the start of this year.

The Seattle Times has a Pulitzer Prize-winning aerospace journalist named Dominic Gates. Sunday he published an expose on "a yearslong decline of safety standards" at Boeing.

After a 1997 merger, its new executive leaders "treated experienced engineers and machinists as expendable, ignoring the potential damage to Boeing's essential mission of designing and building high-quality airplanes...." The arc of Boeing's fall can be traced back a quarter century, to when its leaders elevated the interests of shareholders above all others, said Richard Aboulafia, industry analyst with AeroDynamic Advisory. "Crush the workers. Share price. Share price. Share price. Financial moves and metrics come first," was Boeing's philosophy, he said. It was, he said, "a ruthless effort to cut costs without any realization of what it could do to capabilities...." Its leaders outsourced work, sold off whole divisions and discarded key capabilities such as developing avionics, machining parts and building fuselages. On the 787, they even outsourced the jet's wings to Japan. They moved work away from Boeing's highly skilled, unionized base in the Puget Sound region. They weakened unions and extorted state government with repeated threats to build future airplanes elsewhere. They squeezed suppliers by demanding price cuts every year that in turn forced the suppliers into ruinous cost-cutting and left them vulnerable to collapse during shocks like the COVID-19 pandemic....

Belatedly, Boeing's current leaders, overwhelmed by criticism, mockery and outrage since January, have finally admitted publicly that some key strategies they pursued for decades were flawed. "Boeing, more than 20 years ago, probably got a little too far ahead of itself on the topic of outsourcing," Chief Financial Officer Brian West said last month. And in January, on CNBC, Boeing Chief Executive Dave Calhoun conceded: "Did it go too far? Yeah, probably did."

Both were speaking about major supplier Spirit AeroSystems of Wichita, Kan., part of Boeing until it was sold off two decades ago, part of a broad divestment of assets to please Wall Street and boost the stock. Following a litany of quality lapses in Wichita, Boeing is now admitting a mistake and trying to buy Spirit back — "for safety and for quality," said West. Another mistake belatedly recognized: With annual bonuses for Boeing's factory managers based largely on meeting cost and schedule targets, it was long a cardinal sin to stop the assembly line. That meant unfinished jobs piled up on aircraft as they moved forward down the line, what Boeing calls "traveled work." Done out of sequence, this work is more difficult and takes much longer. If too much traveled work piles up, it creates chaos. That's what happened in Renton on the 737 assembly line. "For years, we prioritized the movement of the airplane through the factory over getting it done right, and that's got to change," West said. "Once you reduce traveled work, your quality gets better...."

Speaking of how Spirit might be fixed, West said: "It's really about focus and running it, not as a business, as a factory. Run it as a factory and stay focused on safety and quality and stability."
Phil Chandler, a highly skilled Boeing machinist for more than 42 years (retiring in 2020), saw a "dictatorial" approach on the factory floor, according to the article. "Whereas in the past, first-level and even second-level managers in the factory had come up through the ranks as mechanics and had deep knowledge of the work, after [Boeing president Harry] Stonecipher came in those jobs shifted to white-collar people with degrees, often with MBAs."

And a former Boeing physicist also complains about the "shoot-the-messenger" management approach when developing their 787, according to the article: "Engineers who raised technical doubts were told: 'Follow the plan. If you can't do your job, I'll fire you and get someone who can.'"

404 Media claims to have identified "the fundamental flaw with the age verification bills and laws" that have already passed in eight state legislatures (with two more taking effect in July): "the delusional, unfounded belief that putting hurdles between people and pornography is going to actually prevent them from viewing porn."

They argue that age verification laws "drag us back to the dark ages of the internet." Slashdot reader samleecole shared this excerpt: What will happen, and is already happening, is that people — including minors — will go to unmoderated, actively harmful alternatives that don't require handing over a government-issued ID to see people have sex. Meanwhile, performers and companies that are trying to do the right thing will suffer....

The legislators passing these bills are doing so under the guise of protecting children, but what's actually happening is a widespread rewiring of the scaffolding of the internet. They ignore long-established legal precedent that has said for years that age verification is unconstitutional, eventually and inevitably reducing everything we see online without impossible privacy hurdles and compromises to that which is not "harmful to minors." The people who live in these states, including the minors the law is allegedly trying to protect, are worse off because of it. So is the rest of the internet.
Yet new legislation is advancing in Kentucky and Nebraska, while the state of Kansas just passed a law which even requires age-verification for viewing "acts of homosexuality," according to a report: Websites can be fined up to $10,000 for each instance a minor accesses their content, and parents are allowed to sue for damages of at least $50,000. This means that the state can "require age verification to access LGBTQ content," according to attorney Alejandra Caraballo, who said on Threads that "Kansas residents may soon need their state IDs" to access material that simply "depicts LGBTQ people."
One newspaper opinion piece argues there's an easier solution: don't buy your children a smartphone: Or we could purchase any of the various software packages that block social media and obscene content from their devices. Or we could allow them to use social media, but limit their screen time. Or we could educate them about the issues that social media causes and simply trust them to make good choices. All of these options would have been denied to us if we lived in a state that passed a strict age verification law. Not only do age verification laws reduce parental freedom, but they also create myriad privacy risks. Requiring platforms to collect government IDs and face scans opens the door to potential exploitation by hackers and enemy governments. The very information intended to protect children could end up in the wrong hands, compromising the privacy and security of millions of users...

Ultimately, age verification laws are a misguided attempt to address the complex issue of underage social media use. Instead of placing undue burdens on users and limiting parental liberty, lawmakers should look for alternative strategies that respect privacy rights while promoting online safety.
This week a trade association for the adult entertainment industry announced plans to petition America's Supreme Court to intervene.

Apple has sued its former employee Andrew Aude for leaking information about more than a half-dozen Apple products and policies, including its then-unannounced Journal app and Vision Pro headset, product development policies, strategies for regulatory compliance, employee headcounts, and more. MacRumors reports: Aude joined Apple as an iOS software engineer in 2016, shortly after graduating college. He worked on optimizing battery performance, making him "privy to information regarding dozens of Apple's most sensitive projects," according to the complaint. In April 2023, for example, Apple alleges that Aude leaked a list of finalized features for the iPhone's Journal app to a journalist at The Wall Street Journal on a phone call. That same month, The Wall Street Journal's Aaron Tilley published a report titled "Apple Plans iPhone Journaling App in Expansion of Health Initiatives."

Using the encrypted messaging app Signal, Aude is said to have sent "over 1,400" messages to the same journalist, who Aude referred to as "Homeboy." He is also accused of sending "over 10,000 text messages" to another journalist at the website The Information, and he allegedly traveled "across the continent" to meet with her. Other leaks relate to the Vision Pro and other hardware: "As another example, an October 2020 screenshot on Mr. Aude's Apple-issued work iPhone shows that he disclosed Apple's development of products within the spatial computing space to a non-Apple employee. Mr. Aude made this disclosure even though Apple's development efforts were confidential and not known to the public. Over the following months, Mr. Aude disclosed additional Apple confidential information -- including information concerning unannounced products, and hardware information."

Apple believes that Aude's actions were "extensive and purposeful," with Aude allegedly admitting that he leaked information so he could "kill" products and features with which he took issue. The company alleges that his wrongful disclosures resulted in at least five news articles discussing the company's confidential and proprietary information. Apple says these public revelations impeded its ability to "surprise and delight" with its latest products. Apple said it learned of Aude's wrongful disclosures in late 2023, and the company fired him for his alleged misconduct in December of that year. [...] Apple is seeking both compensatory and punitive damages in an amount to be determined at trial, and it is also seeking other legal remedies. The full complaint can be read here (PDF).

Slashdot reader christoban writes: In what may be an issue for Sun-obscuring strategies to combat global warming, it turns out that during solar eclipses, low level cumulus clouds rapidly disappear, reducing by a factor of 4, researchers have found. The news comes from the science magazine Eos (published by the nonprofit organization of atmosphere/ocean/space scientists, the American Geophysical Union). Victor J. H. Trees, a geoscientist at Delft University of Technology in the Netherlands, and his colleagues recently analyzed cloud cover data obtained during an annular eclipse in 2005, visible in parts of Europe and Africa. They mined visible and infrared imagery collected by two geostationary satellites operated by the European Organisation for the Exploitation of Meteorological Satellites. Going to space was key, Trees said. "If you really want to quantify how clouds behave and how they react to a solar eclipse, it helps to study a large area. That's why we want to look from space...." [T]hey tracked cloud evolution for several hours leading up to the eclipse, during the eclipse, and for several hours afterward.

Low-level cumulus clouds — which tend to top out at altitudes around 2 kilometers (1.2 miles) — were strongly affected by the degree of solar obscuration. Cloud cover started to decrease when about 15% of the Sun's face was covered, about 30 minutes after the start of the eclipse. The clouds started to return only about 50 minutes after maximum obscuration. And whereas typical cloud cover hovered around 40% in noneclipse conditions, less than 10% of the sky was covered with clouds during maximum obscuration, the team noted. "On a large scale, the cumulus clouds started to disappear," Trees said... The temperature of the ground matters when it comes to cumulus clouds, Trees said, because they are low enough to be significantly affected by whatever is happening on Earth's surface...

Beyond shedding light on the physics of cloud dissipation during solar eclipses, these new findings also have implications for future geoengineering efforts, Trees and his collaborators suggested. Discussions are underway to mitigate the effects of climate change by, for instance, seeding the atmosphere with aerosols or launching solar reflectors into space to prevent some of the Sun's light from reaching Earth. Such geoengineering holds promise for cooling our planet, researchers agree, but its repercussions are largely unexplored and could be widespread and irreversible.

These new results suggest that cloud cover could decrease with geoengineering efforts involving solar obscuration. And because clouds reflect sunlight, the efficacy of any effort might correspondingly decrease, Trees said. That's an effect that needs to be taken into account when considering different options, the researchers concluded.
Another article on the site warns that "Planting Trees May Not Be as Good for the Climate as Previously Believed."

"The climate benefits of trees storing carbon dioxide is partially offset by dark forests' absorption of more heat from the Sun, and compounds they release that slow the destruction of methane in the atmosphere."

An article in Inc notes a "wild projection" in Reddit's SEC filing that Reddit's global market opportunity by 2027 is $1.4 trillion." Some of the numbers lead back to a single individual: Sam Altman. The co-founder and chief executive of ChatGPT-maker OpenAI owns an 8.7 percent stake in Reddit, more than its co-founder and CEO, Steve Huffman, who owns 3.3 percent... Altman, through various funds and holding companies he owns or manages, controls more than a million shares of Reddit at $60 million in aggregate purchase price — and holds more than 9 percent of voting rights...

Discussing Reddit's future, financial analyst and journalist Herb Greenberg recently told CNBC, "This is an AI play."
But the senior investing editor for Kiplinger.com argues that retail investors "may want to hold tight before rushing out to buy the Reddit IPO." While IPO stocks tend to have strong first-day showings, returns for the first year are generally weak, says the team of analysts at Trivariate Research, a market research firm based in New York. And since 2020, "the average IPO has lagged its industry average by 30% over the subsequent three years following its first closing price..."

Other commenters have noted that Reddit's allotment of shares to select Redditors could lower demand on the first day of trading, which would work against any IPO pop.
"Over the past few years, there have been a bunch of IPOs in the U.S. in which overhyped names enjoyed flashy stock-market debuts only to drop sharply soon after," notes the Street. Notable examples include Coinbase, which plummeted by almost 90% after its debut, Robinhood, still down 53% since its IPO, and Rivian, down over 91% since its debut. However, it's crucial to note that all of these IPOs occurred in 2021 amid market euphoria fueled by low interest rates, significant economic stimulus, and the lingering effects of the Covid-19 pandemic. Although the current macroeconomic landscape differs from three years ago, valuations of tech and growth stocks remain stretched.
Kiplingers.com concludes it "boils down to your own personal investing goals and risk tolerance. If you do decide to buy Reddit stock when it first begins trading, do so in a small amount that you can afford to lose."

But they also cite analysis from David Trainer, CEO of New Constructs, a research firm powered by artificial intelligence. "Reddit's IPO marks the return of the junk IPO," Trainer wrote in Forbes. "[The valuation] implies that Reddit will grow its user base to 26 times current levels, which would be nearly five times the size of [Snapchat-maker] Snap, and a highly unlikely feat. Reddit looks overvalued, and we think investors should pass on this IPO."

Trainer writes: [T]he company has never been profitable and should not be a publicly traded company... I think the company may never monetize its platform without angering its users and the entire premise of Reddit is user-generated content. This business model is inescapably built on a catch-22: make money or please users... Reddit looks overvalued, and I think investors should pass on this IPO.
Buyers and analysts told the site Marketing Brew "that they see the platform as nice-to-have, but that it is not an essential part of their media plans, like Meta or Google are." "They've always been solidly in the second or third tier of social networks," alongside Snap, Pinterest, and X, Brian Wieser, a former GroupM exec who's now author of the industry newsletter Madison and Wall, told Marketing Brew.
Yet Trainer notes that "98% of Reddit's revenue in 2023 came from third-party advertising on the site and 28% of all revenue came from ten customers," and "Reddit's cost of revenue, sales & marketing, general & administrative, and research & development costs were 117% of revenue in 2023."

Trainer concludes "Reddit is nowhere near breakeven. Reddit is an unprofitable social media company fighting for users."

Bloomberg adds that the subreddit r/WallStreetBets "has threatened to bet against the stock, with many people noting that the company still loses money two decades into its existence. (Reddit lost $90.8 million last year, down from $158.6 million the year before.)" Some have complained that the invitation to invest fails to make up for the unpaid labor they've invested making the site work... In 2021 the platform's WallStreetBets forum ignited a meme-stock frenzy, propelling skyward the stocks of nostalgic but struggling companies like GameStop Corp. and AMC Entertainment Holdings Inc. and sending shockwaves through the financial industry... When it goes public, the platform that invented meme stocks runs the risk of becoming one itself.

Reddit noted the possibility as a risk in its IPO filing. "Given the broad awareness and brand recognition of Reddit, including as a result of the popularity of r/wallstreetbets among retail investors," the company warned that its stock could "experience extreme volatility ... which could cause you to lose all or part of your investment if you are unable to sell your shares at or above the initial offering price."

Users on WallStreetBets got a kick out of the fact that the company listed the forum as a risk factor, posting about it with a sly smiling emoji...
Meanwhile, reports that marketers are infiltrating subreddits have been confirmed. Over 200 businesses have "integrated Reddit Pro into their digital strategies," reports Search Engine Land, including "well-known names such as Taco Bell, the NFL, and The Wall Street Journal...

"During the initial alpha testing phase with approximately 20 businesses, Reddit reported its Pro partners, on average, generated 11 additional posts and comments per month."

The hype around AI language models has companies scrambling to hire prompt engineers to improve their AI queries and create new products. But new research hints that the AI may be better at prompt engineering than humans, indicating many of these jobs could be short-lived as the technology evolves and automates the role. IEEE Spectrum: Battle and Gollapudi decided to systematically test [PDF] how different prompt engineering strategies impact an LLM's ability to solve grade school math questions. They tested three different open source language models with 60 different prompt combinations each. What they found was a surprising lack of consistency. Even chain-of-thought prompting sometimes helped and other times hurt performance. "The only real trend may be no trend," they write. "What's best for any given model, dataset, and prompting strategy is likely to be specific to the particular combination at hand."

There is an alternative to the trial-and-error style prompt engineering that yielded such inconsistent results: Ask the language model to devise its own optimal prompt. Recently, new tools have been developed to automate this process. Given a few examples and a quantitative success metric, these tools will iteratively find the optimal phrase to feed into the LLM. Battle and his collaborators found that in almost every case, this automatically generated prompt did better than the best prompt found through trial-and-error. And, the process was much faster, a couple of hours rather than several days of searching.

An anonymous reader quotes a report from The Guardian: A global coalition of democracies is being formed to protect their societies from disinformation campaigns by foreign governments, the US special envoy on the issue has said. James Rubin, the special envoy for non-state propaganda and disinformation efforts at the US state department's global engagement centre (GEC), said the coalition hoped to agree on "definitions for information manipulation versus plain old opinions that other governments are entitled to have even if we disagree with them." The US, UK and Canada have already signed up to a formal framework agreement, and Washington hopes more countries will join.

The GEC focuses solely on disinformation by foreign powers. Apart from trying to develop global strategies, it works to expose specific covert disinformation operations, such as a Russian operation in Africa to discredit US health services. The US, UK and Canada signed the framework to counter foreign state manipulation this month with the aim of addressing disinformation as a national security threat that requires coordinated government and civil society responses. "Now is the time for a collective approach to the foreign information manipulation threat that builds a coalition of like-minded countries committed to strengthening resilience and response to information manipulation," the framework says. It also encourages information-sharing and joint data analysis tools to identify covert foreign disinformation.

A hugely experienced US official and journalist who has worked with diplomats such as Madeleine Albright in the past, Rubin admitted his first year as special envoy had been one of his most intellectually taxing because of the complex definitions surrounding disinformation. In the continuum between hostile opinion and disinformation, he has tried to identify where and how governments can intervene without limiting free speech. The principle on which he has alighted is deception by foreign powers. "In principle every government should be free to convey their views, but they should have to admit who they are," he said an interview. "We want to promote more fact-based information, but at the same time find ways to label those information operations that are generated by the Chinese government or the Kremlin but to which they don't admit. "In the end that is all I know we can do right now without interfering with a free press. We are not asking for such covert disinformation to be taken down but a way to be found for the source to be labelled."

Disney is outsourcing its DVD and Blu-ray disc business to Sony Pictures Entertainment. Variety reports: As part of the deal, Sony will market, sell and distribute all Disney's new releases and catalog titles on physical media to consumers through retailers and distributors in the U.S. and Canada. Disney will continue to manage its own digital media, like premium video-on-demand. It's unclear if this will result in layoffs at Disney. However, the studio is expected to conduct an internal assessment across all business functions that support physical entertainment amid the transition to Sony, according to sources familiar with the agreement.

According to Disney, the licensing model allows the studio to continue to offer films and TV shows through physical retailers and to respond to consumer demand more efficiently. The company said the shift is consistent with strategies it's implemented companywide, as well as transitions in other markets.

An anonymous reader shares a report: In a concession to automakers and labor unions, the Biden administration intends to relax elements of one of its most ambitious strategies to combat climate change, limits on tailpipe emissions that are designed to get Americans to switch from gas-powered cars to electric vehicles, according to three people familiar with the plan. Instead of essentially requiring automakers to rapidly ramp up sales of electric vehicles over the next few years, the administration would give car manufacturers more time [non-paywalled source], with a sharp increase in sales not required until after 2030, these people said. They asked to remain anonymous because the regulation has not been finalized. The administration plans to publish the final rule by early spring.

The change comes as President Biden faces intense crosswinds as he runs for re-election while trying to confront climate change. He is aiming to cut carbon dioxide emissions from gasoline-powered vehicles, which make up the largest single source of greenhouse gases emitted by the United States. At the same time, Mr. Biden needs cooperation from the auto industry and political support from the unionized auto workers who backed him in 2020 but now worry that an abrupt transition to electric vehicles would cost jobs. Meanwhile, consumer demand has not been what automakers hoped, with potential buyers put off by sticker prices and the relative scarcity of charging stations. The EPA last year proposed the toughest-ever limits on tailpipe emissions. The rules would be so strict, the only way car makers could comply would be to sell a tremendous number of zero-emissions vehicles in a relatively short time frame. The E.P.A. designed the proposed regulations so that 67% of sales of new cars and light-duty trucks would be all-electric by 2032, up from 7.6% in 2023, a radical remaking of the American automobile market.

Martin Hellman "achieved legendary status as co-inventor of the Diffie-Hellman public key exchange algorithm, a breakthrough in software and computer cryptography," notes a new interview in InfoWorld.

Nine years after winning the Turing award, the 78-year-old cryptologist shared his perspective on some other issues: What do you think about the state of digital spying today?

Hellman: There's a need for greater international cooperation. How can we have true cyber security when nations are planning — and implementing — cyber attacks on one another? How can we ensure that AI is used only for good when nations are building it into their weapons systems? Then, there's the grandaddy of all technological threats, nuclear weapons. If we keep fighting wars, it's only a matter of time before one blows up.

The highly unacceptable level of nuclear risk highlights the need to look at the choices we make around critical decisions, including cyber security. We have to take into consideration all participants' needs for our strategies to be effective....

Your battle with the government to make private communication available to the general public in the digital age has the status of folklore. But, in your recent book (co-authored with your wife Dorothie [and freely available as a PDF]), you describe a meeting of minds with Admiral Bobby Ray Inman, former head of the NSA. Until I read your book, I saw the National Security Agency as bad and Diffie-Hellman as good, plain and simple. You describe how you came to see the NSA and its people as sincere actors rather than as a cynical cabal bent on repression. What changed your perspective?

Hellman: This is a great, real-life example of how taking a holistic view in a conflict, instead of just a one-sided one, resolved an apparently intractable impasse. Those insights were part of a major change in my approach to life. As we say in our book, "Get curious, not furious." These ideas are effective not just in highly visible conflicts like ours with the NSA, but in every aspect of life.
Hellman also had an interesting answer when asked if math, game theory, and software development teach any lessons applicable to issues like nuclear non-proliferation or national defense.

"The main thing to learn is that the narrative we (and other nations) tell ourselves is overly simplified and tends to make us look good and our adversaries bad."
