An anonymous Slashdot reader shared this report from The Washington Post: A YouTube contractor was addressing the Austin City Council on Thursday, calling on them to urge Google to negotiate with his union, when a colleague interrupted him with jaw-dropping news: His 43-person team of contractors had all been laid off...

The YouTube workers, who work for Google and Cognizant, unanimously voted to unionize under the Alphabet Workers Union-CWA in April 2023. Since then, the workers say that Google has refused to bargain with them. Thursday's layoff signifies continued tensions between Google and its workers, some of whom in 2021 formed a union...

Workers had about 20 minutes to gather their belongings and leave the premises before they were considered trespassing.
Video footage of the moment is embedded at the top of the article. "I was speechless, shocked," said the contractor who'd been speaking. He told the Washington Post "I didn't know what to do. But angered, that was the main feeling." The council meeting was streaming live online and has since spread on social media. The contractors view the layoff as retaliation for unionizing, but Google and information technology subcontractor Cognizant said it was the normal end of a business contract.

The ability for layoffs to spread over social media highlights how the painful experience of a job loss is frequently being made public, from employees sharing recordings of Zoom meetings to posting about their unemployment. The increasing tension between YouTube's contractors and Google comes as massive layoffs continue to hit the tech industry — leaving workers uneasy and companies emboldened. Google already has had rounds of cuts the past two years.

Google has been in a long-running battle with many of its contractors as they seek the perks and high pay that full-time Google workers are accustomed to. The company has tens of thousands of contractors doing everything from food service to sales to writing code... Google maintains that Cognizant is responsible for the contractors' employment and working conditions, and therefore isn't responsible for bargaining with them. Cognizant said it is offering the workers seven weeks of paid time to explore other roles at the company and use its training resources.

Last year, the National Labor Relations Board ruled that Cognizant and Google are joint employers of the contractors. In January, the NLRB sent a cease-and-desist letter to both employers for failing to bargain with the union. Since then the issue of joint employment, which would ultimately determine which company is responsible for bargaining, has landed in an appeals court and has yet to be ruled on.
"Workers say they don't have sick pay, receive minimal benefits and are paid as little as $19 an hour," according to the article, "forcing some to work multiple jobs to make ends meet." Sam Regan, a data analyst contractor for YouTube Music, told the Washington Post that he was one of the last workers to leave the meeting where the layoffs were announced.

"Upon leaving, he heard one of the security guards call the non-emergency police line to report trespassers."

The desert planet Arrakis in Frank Herbert's science fiction novel Dune is plausible, says Alexander Farnsworth, a climate modeler at the University of Bristol in England. According to Science News, the world would be a harsh place for humans to live, and they probably wouldn't have to worry about getting eaten by extraterrestrial helminths. From the report: For their Arrakis climate simulation, which you can explore at the website Climate Archive, Farnsworth and colleagues started with the well-known physics that drive weather and climate on Earth. Using our planet as a starting point makes sense, Farnsworth says, partly because Herbert drew inspiration for Arrakis from "some sort of semi-science of looking at dune systems on the Earth itself." The team then added nuggets of information about the planet from details in Herbert's novels and in the Dune Encyclopedia. According to that intel, the fictional planet's atmosphere is similar to Earth's with a couple of notable differences. Arrakis has less carbon dioxide in the atmosphere than Earth -- about 350 parts per million on the desert planet compared with 417 parts per million on Earth. But Dune has far more ozone in its lower atmosphere: 0.5 percent of the gases in the atmosphere compared to Earth's 0.000001 percent.

All that extra ozone is crucial for understanding the planet. Ozone is a powerful greenhouse gas, about 65 times as potent at warming the atmosphere as carbon dioxide is, when measured over a 20-year period. "Arrakis would certainly have a much warmer atmosphere, even though it has less CO2 than Earth today," Farnsworth says. In addition to warming the planet, so much ozone in the lower atmosphere could be bad news. "For humans, that would be incredibly toxic, I think, almost fatal if you were to live under such conditions," Farnsworth says. People on Arrakis would probably have to rely on technology to scrub ozone from the air. Of course, ozone in the upper atmosphere could help shield Arrakis from harmful radiation from its star, Canopus. (Canopus is a real star also known as Alpha Carinae. It's visible in the Southern Hemisphere and is the second brightest star in the sky. Unfortunately for Dune fans, it isn't known to have planets.) If Arrakis were real, it would be located about as far from Canopus as Pluto is from the sun, Farnsworth says. But Canopus is a large white star calculated to be about 7,200 degrees Celsius. "That's significantly hotter than the sun," which runs about 2,000 degrees cooler, Farnsworth says. But "there's a lot of supposition and assumptions they made in here, and whether those are accurate numbers or not, I can't say."

The climate simulation revealed that Arrakis probably wouldn't be exactly as Herbert described it. For instance, in one throwaway line, the author described polar ice caps receding in the summer heat. But Farnsworth and colleagues say it would be far too hot at the poles, about 70Â C during the summer, for ice caps to exist at all. Plus, there would be too little precipitation to replenish the ice in the winter. High clouds and other processes would warm the atmosphere at the poles and keep it warmer than lower latitudes, especially in the summertime. Although Herbert's novels have people living in the midlatitudes and close to the poles, the extreme summer heat and bone-chilling -40C to -75C temperatures in the winters would make those regions nearly unlivable without technology, Farnsworth says. Temperatures in Arrakis' tropical latitudes would be relatively more pleasant at 45C in the warmest months and about 15C in colder months. On Earth, high humidity in the tropics makes it far warmer than at the poles. But on Arrakis, "most of the atmospheric moisture was essentially removed from the tropics," making even the scorching summers more tolerable. The poles are where clouds and the paltry amount of moisture gather and heat the atmosphere. But the tropics on Arrakis pose their own challenges. Hurricane force winds would regularly sandblast inhabitants and build dunes up to 250 meters tall, the researchers calculate. It doesn't mean people couldn't live on Arrakis, just that they'd need technology and lots of off-world support to bring in food and water, Farnsworth says. "I'd say it's a very livable world, just a very inhospitable world."

Eating ultraprocessed foods raises the risk of developing or dying from dozens of adverse health conditions, according to a new review of 45 meta-analyses on almost 10 million people. From a report: "We found consistent evidence linking higher intakes of ultra-processed foods with over 70% of the 45 different health outcomes we assessed," said senior author Wolfgang Marx, a senior research fellow at the Food & Mood Centre at Deakin University in Geelong, Australia, in an email. A higher intake was considered about one serving or about 10% more ultraprocessed foods per day, said Heinz Freisling, a scientist in the nutrition and metabolism branch of the World Health Organization's International Agency for Research on Cancer, in an email.

"This proportion can be regarded as 'baseline' and for people consuming more than this baseline, the risk might increase," said Freisling, who was not involved in the study. Researchers graded each study as having credible or strong, highly suggestive, suggestive, weak or no evidence. All the studies in the review were published in the past three years, and none was funded by companies involved in the production of ultraprocessed foods, the authors said. "Strong evidence shows that a higher intake of ultra-processed foods was associated with approximately 50% higher risk of cardiovascular disease-related death and common mental disorders," said lead author Dr. Melissa Lane, a postdoctoral research fellow at Deakin, in an email. Cardiovascular disease encompasses heart attacks, stroke, clogged arteries and peripheral artery disease.

Jacob Kaplan-Moss, one of the lead developers of Django, writes in a long post that he says has come from a place of frustration: [...] Instead, every time a maintainer finds a way to get paid, people show up to criticize and complain. Non-OSI licenses "don"t count" as open source. Someone employed by Microsoft is "beholden to corporate interests" and not to be trusted. Patreon is "asking for handouts." Raising money through GitHub sponsors is "supporting Microsoft's rent-seeking." VC funding means we're being set up for a "rug pull" or "enshitification." Open Core is "bait and switch."

None of this is hypothetical; each of these examples are actual things I've seen said about maintainers who take money for their work. One maintainer even told me he got criticized for selling t-shirts! Look. There are absolutely problems with every tactic we have to support maintainers. It's true that VC investment comes with strings attached that often lead to problems down the line. It sucks that Patreon or GitHub (and Stripe) take a cut of sponsor money. The additional restrictions imposed by PolyForm or the BSL really do go against the Freedom 0 ideal. I myself am often frustrated by discovering that some key feature I want out of an open core tool is only available to paid licensees.

But you can criticize these systems while still supporting and celebrating the maintainers! Yell at A16Z all you like, I don't care. (Neither do they.) But yelling at a maintainer because they took money from a VC is directing that anger in the wrong direction. The structural and societal problems that make all these different funding models problematic aren't the fault of the people trying to make a living doing open source. It's like yelling at someone for shopping at Dollar General when it's the only store they have access to. Dollar General's predatory business model absolutely sucks, as do the governmental policies that lead to food deserts, but none of that is on the shoulders of the person who needs milk and doesn't have alternatives.

Over the past four centuries quadrillions of ants have created a strange and turbulent global society that shadows our own. An excerpt from an Aeon article: In their native ranges, these multi-nest colonies can grow to a few hundred metres across, limited by physical barriers or other ant colonies. This turns the landscape to a patchwork of separate groups, with each chemically distinct society fighting or avoiding others at their borders. Species and colonies coexist, without any prevailing over the others. However, for the 'anonymous societies' of unicolonial ants, as they're known, transporting a small number of queens and workers to a new place can cause the relatively stable arrangement of groups to break down. As new nests are created, colonies bud and spread without ever drawing boundaries because workers treat all others of their own kind as allies. What was once a patchwork of complex relationships becomes a simplified, and unified, social system. The relative genetic homogeneity of the small founder population, replicated across a growing network of nests, ensures that members of unicolonial species tolerate each other. Spared the cost of fighting one another, these ants can live in denser populations, spreading across the land as a plant might, and turning their energies to capturing food and competing with other species. Chemical badges keep unicolonial ant societies together, but also allow those societies to rapidly expand.

Fast food chain Wendy's announced it's adopting a similar approach to Uber's Surge Pricing policy by dynamically adjusting the prices of its menu items during peak demand periods at certain locations. The controversial strategy seeks to leverage real-time data to align pricing and demand, enhancing efficiency and potentially improving customer satisfaction. From a report: During a conference call earlier this month, Wendy's CEO Kirk Tanner said the fast-food chain would experiment with dynamic pricing as early as next year. "Beginning as early as 2025, we will begin testing more enhanced features like dynamic pricing and daypart offerings, along with AI-enabled menu changes and suggestive selling," he said. "As we continue to show the benefit of this technology in our company-operated restaurants, franchisee interest in digital menu boards should increase, further supporting sales and profit growth across the system."

Prices seesaw all the time on the sites of online retailers like Amazon that use algorithms and artificial intelligence to monitor competitors and glean insights into individual shoppers, adjusting prices depending on interest in the product or in the brand, said Timothy Webb, an assistant professor at the University of Delaware's hospitality and sport business management program. Coupons and other offers are also routinely dangled in mobile apps to encourage people to make purchases. "A lot of this stuff is already happening even if you don't realize that it is happening. If you have the Starbucks app and I have the Starbucks app, we probably have different offers," Webb said. "We might not be in the drive-through and they just increased the prices, but we are already paying different prices for the same products."

But, he says, Wendy's fans will likely see moderate, not massive, price swings during periods of peak demand. "It's not like $200 or $300 on a flight. This is a hypercompetitive industry. If Wendy's goes up $2 to $3 on a burger at dinner time, I would be shocked. People have too many options. They will just walk down the street and eat at Burger King instead," Webb said. "There will just be little price changes here."

Emanuel Maiberg reports via 404 Media: Dozens of Ghost kitchens, restaurants that serve food exclusively by delivery on apps like DoorDash and Grubhub, are selling food that they promote to customers with AI-generated images. It's common for advertisements to stage or edit pictures of food to make it look more enticing, but in these cases the ghost kitchens are showing people pictures of food that literally doesn't exist, and looks nothing like the actual items they're selling, sometimes because the faulty AI is producing physically impossible food items. [...] Some ghost kitchens exist as unmarked commercial kitchens with no actual restaurant you can visit that simply fulfill orders for a variety of brands that only exist on the food delivery services. Other ghost kitchens piggyback on existing, real restaurant kitchens to fulfill orders for those brands that exist only on food delivery apps.

[The food from a business on DoorDash called Pasta Lovers] actually comes from Tony's Pizzeria in North Brooklyn, which also fulfills orders for a cheesesteak brand called Philly Cheez, a hero sandwich brand called Hero Mania, and a wrap brand called That's A Wrap. All of these brands deliver food from different ghost kitchens across the country, and all of them feature the same type of AI-generated images to promote their food, some of which looks ridiculous. [...]

"We don't allow the use of AI-generated images and if we find a merchant is using any, we will remove those images from their menu," Grubhub, which also operates Seamless, told me in an email. However, at the time of writing the AI-generated images on Seamless I sent the company are still live on its site. "We know how important it is for diners to have realistic expectations of what they are ordering and should expect to receive, which is why we share image guidelines with our partners and our system reviews image submissions before they're allowed on our platform." "DoorDash is committed to showcasing realistic representations of meals that customers would receive when ordering online," DoorDash told me in an email. "Showcasing high-quality, accurate, and realistic menu images is crucial for maintaining customer trust and generating sales through DoorDash Marketplace." "This is all incredibly depressing," concludes Maiberg. "A local pizzeria can't get by unless it makes sandwiches for ghost kitchen brands, the people who make a living taking photographs of food are being displaced by AI tools, and gigantic food delivery apps are still making money by taking a cut from restaurants and screwing over gig delivery drivers."

"AI-generated images of food that people can order and eat finally brings us to a shockingly literal manifestation of Jean Baudrillard's Simulacra. Baudrillard would say the Spicy Philly Cheese from Philly Cheez is "never that which conceals the truth -- it is the truth which conceals that there is none."

Apple has filed a lawsuit against the U.S. Patent and Trademark Office for refusing to grant trademarks covering the company's augmented-reality software development tools "Reality Composer" and "Reality Converter." Reuters reports: Apple, whose augmented-reality technology is a centerpiece of its newly released Vision Pro headset, asked the court (PDF) on Friday to reverse the USPTO's decision that the phrases were not distinctive enough to receive federal trademark protection. "Consumers must exercise imagination to understand how the nonsensical phrases 'reality composer' and 'reality converter' -- which sound like science fiction impossibilities -- relate to Apple's products," the complaint said. "They are suggestive, just as Burger King is a fast-food chain, not an actual monarch."

Apple's Reality Composer and Reality Converter allow developers to create and alter 3-D augmented-reality content for Apple apps. The content is compatible with Apple devices including the Vision Pro mixed-reality headset, which the tech giant began selling earlier this month. Turkish visual-effects company ZeroDensity challenged Apple's trademark applications at the USPTO, arguing that the phrases could not receive federal trademarks because they merely describe what the software does. ZeroDensity also said Apple's trademarks would cause confusion with its own "Reality"-related marks.

ZeroDensity, the named defendant in the case, said in a statement on Monday that it was "surprised and concerned by [Apple's] misinterpretation and misrepresentation of our company" and is "resolute in defending our 'Reality' trademarks." A USPTO tribunal agreed with ZeroDensity that Apple's marks were descriptive without addressing whether they would confuse consumers. Apple said in Friday's complaint that its phrases were "made-up terms coined by Apple that do not describe the underlying software development tools." "In contrast, descriptive terms like Raisin Bran or American Airlines straightforwardly describe the goods and services offered under the brand name," Apple said. "As innovative as Apple is, it cannot 'compose' or 'convert' reality." Apple argued that its marks would not cause consumer confusion and accused ZeroDensity of trying to "claim broad rights in the word 'reality,' which no one entity can monopolize."

Switzerland is advocating for a United Nations expert group to explore the merits of solar geoengineering. The proposal seeks to ensure multilateral oversight of solar radiation modification (SRM) research, amidst concerns over its potential implications for food supply, biodiversity, and global inequalities. The Guardian reports: The Swiss proposal, submitted to the United Nations environment assembly that begins next week in Nairobi, focuses on solar radiation modification (SRM). This is a technique that aims to mimic the effect of a large volcanic eruption by filling the atmosphere with sulphur dioxide particles that reflect part of the sun's heat and light back into space. Supporters of the proposal, including the United Nations environment program (UNEP), argue that research is necessary to ensure multilateral oversight of emerging planet-altering technologies, which might otherwise be developed and tested in isolation by powerful governments or billionaire individuals.

Critics, however, argue that such a discussion would threaten the current de-facto ban on geoengineering, and lead down a "slippery slope" towards legitimization, mainstreaming and eventual deployment. Felix Wertli, the Swiss ambassador for the environment, said his country's goal in submitting the proposal was to ensure all governments and relevant stakeholders "are informed about SRM technologies, in particular about possible risks and cross-border effects." He said the intention was not to promote or enable solar geoengineering but to inform governments, especially those in developing countries, about what is happening.

The executive director of the UNEP, Inger Andersen, stressed the importance of "a global conversation on SRM" in her opening address to delegates at a preliminary gathering in Nairobi. She and her colleagues emphasized the move was a precautionary one rather than an endorsement of the technology.

An anonymous reader shares a report: I hate cookbooks without pictures. We eat with our eyes first, as chefs love to say, but what's more important to me is that if I'm making a dish for the first time, I want to see what the final product should look like to know I did it right. It's not so much about presentation as it is about knowing that I browned the chicken skin enough. An image of a recipe will not be this useful, I think, if it was AI-generated, and especially so if the fact that the image was AI-generated wasn't disclosed by the recipe. That, to my surprise, is exactly the case with thousands of recipes the grocery delivery service Instacart is suggesting to its users. Some of the recipes include unheard of measurements and ingredients that don't appear to exist.

[...] As I was browsing, I noticed that Instacart was offering me recipes that appeared to complement the ingredients I was looking at. The concept doesn't make a ton of sense to me -- I'm going to Instacart for the ingredients I know I need for the food I know I'm going to make, not for food inspo -- but I had to click on a recipe for "Watermelon Popsicle with Chocolate Chips" because it looked weird in the thumbnail. Since I have eyeballs with optical nerves that are connected to a semi-functioning brain I can tell that the image was generated by AI. To be more specific, I can see that the top corner of the plate doesn't match its square shape, that the table-ish looking thing it's resting on is made up of jumbled slats (AI is particularly bad at making these series of long, straight lines), and then there are the titular watermelon popsicles, which defy physical reality. They clip into each other like bad 3D models in a video game, one of them to the left appears hollow, and for some reason they are skewered by what appears to be asparagus spears on the bottom end and capped by impossible small watermelon rinds at the top.

Medical alarms don't have to be louder to be more effective. Scientific American: Beeping alarms in hospitals are a life-or-death matter -- but with so many going off all the time, medical professionals may experience alarm fatigue that impairs care. Researchers now report that changing an alarm's sound to incorporate properties of musical instruments can make it more helpful amid the din. Auditory alarms can sound up to 300 times a day per patient in U.S. hospitals, but only a small fraction require immediate action.

Data from the U.S. Food and Drug Administration suggest that alarm fatigue (including when clinicians turned off or forgot to restart alarms) and other alarm-related issues were linked to 566 deaths over five and a half years. After a typical day at the hospital, "I'd leave with beeping in my ears," says Vanderbilt University Medical Center anesthesiologist Joseph Schlesinger. He collaborated with Michael Schutz, a music cognition researcher at McMaster University in Ontario, to analyze how musical sounds could improve hospital alarms.

In 2015 Schutz and Schlesinger began examining musical qualities called timbres that might let softer sounds command attention from busy clinicians. They found that sounds with a "percussive" timbre, many of which contain short bursts of high-frequency energy -- such as wineglasses clinking -- stand out even at low volume. In contrast, loud, "flat" tones that lack high-frequency components, like a reversing truck's beep, get lost. The researchers have since conducted experiments in which participants evaluate different sounds and melodies for annoyance, detectability and recognizability. For a recent study detailed in Perioperative Care and Operating Room Management, the researchers played participants the same sequences of notes with varying timbres. They found the sounds that made these sequences least annoying, with no decrease in recall, were percussive and had complex, time-varied harmonic overtones (the many components within a single sound) like a xylophone's ping, rather than a few homogeneous ones like monotonous mechanical beeps.

"After years of rapid expansion, California's booming EV market may be showing signs of fatigue," reports the Los Angeles Times, "as high vehicle prices, unreliable charging networks and other consumer headaches appear to dampen enthusiasm for zero-emission vehicles.

"For the first time in more than a decade, electric vehicle sales dropped significantly in the last half of 2023..." Sales of all-electric cars and light trucks in California had started off strong in 2023, rising 48% in the first half of the year compared with a year earlier. By that time, California EV sales numbered roughly 190,807 — or slightly more than a quarter of all EV sales in the nation, according to the California New Car Dealers Assn. But it's what happened in the second half of last year though that's generating jitters. Sales in the third quarter fell by 2,840 from the previous period — the first quarterly drop for EVs in California since the Tesla Model S was introduced in 2012. And the fourth quarter was even worse: Sales dropped 10.2%, from 100,151 to 89,933...

Propelled by the sales success of Tesla, and boosted by electric vehicles from other automakers entering the market, consumer acceptance of EVs had seemed like a given until recently. In fact, robust sales growth is a key assumption in the state's zero-emission vehicle plan... Under the no-gas mandate, zero-emission vehicles must account for 35% of all new vehicle sales by model year 2026.... Nationally, EV sales growth also has slowed as automakers such as Ford and General Motors cut back — at least temporarily — on EV and battery production plans. Hertz, the rental car giant, is also pulling back on plans to shift heavily toward EVs. Hertz several years ago announced plans to buy 100,000 Teslas but is now selling off its EV fleet.

Corey Cantor, EV analyst at Bloomberg BNEF, an energy research firm, said that although recent sales figures are worrisome, there's plenty of momentum behind the EV transition, as evidenced by government mandates around the globe and massive investments by motor vehicle manufacturers and their suppliers. Those investments total $616 billion globally over five years, according to consulting firm AlixPartners.
But EVs haven't reached "price parity" with gas-powered engines, the article points out, so just 7.6% of the vehicles sold last year in the U.S. were electric — while in California, the market share for EVS was 20.1%.

The article also quantifies concerns about reliability of California's public charging system, which "according to studies from academic researchers and market analysts, can be counted on to malfunction at least 20% of the time." After $1 billion in state money for charger companies, the state's Energy Commission will now also start collecting reliability statistics, according to the article. But the article also cites wait times at the chargers. "Even if they were reliable, there aren't enough chargers to go around. EV sales have outpaced public charger installation."

Some good news? The federal government is spending $5 billion nationally to put fast chargers on major highways at 50-mile intervals. California will receive $384 million. Seven major automakers have also teamed up to build a North American charging network of their own, called Ionna. The joint venture plans to install at least 30,000 chargers — which would be open to any EV brand — at stations that will provide restrooms, food service and retail stores on site or nearby.

By 2022 the VC firm Sequoia Capital had about $85 billion in assets under management, according to Wikipedia. Its successful investments include Google, Apple, PayPal, Zoom, and Nvidia.

And now the VC firm "plans to fund up to three open source software developers annually," according to TechCrunch, which notes it "a continuation of a program it debuted last year." The Silicon Valley venture capital firm announced the Sequoia Open Source Fellowship last May, but it was initially offered on an invite-only basis with a single recipient to shout about so far. Moving forward, Sequoia is inviting developers to apply for a stipend that will cover their costs for up to a year so they can work full-time on the project — without giving up any equity or ownership.... "The open source world is to some extent divided between the projects that can be commercialized and the projects that are very important, very influential, but just simply can't become companies," said Sequoia partner Bogomil Balkansky. "For the ones that can become great companies, we at Sequoia have a long track record of partnering with them and we will continue partnering with those founders and creators."

And this is why Sequoia is making two distinct financial commitments to two different kinds of open source entities, using grants to support foundational projects that might be instrumental to one of the companies it's taking a direct equity stake in. "In order for Sequoia to succeed, and for our portfolio of companies that we partner with to succeed, there is this vital category of open source developer work that must be supported in order for the whole ecosystem to work well," Balkansky added. From today, Sequoia said it will accept applications from "any developer" working on an open source project, with considerations made on a "rolling basis" moving forward. Funding will include living expenses paid through monthly installments lasting up to a year, allowing the developer to focus entirely on the project without worrying about how to put food on the table.
Spotify, Salesforce and even Bloomberg have launched their own grant programs too, the article points out.

"But these various funding initiatives have little to do with pure altruism. The companies ponying up the capital typically identify the open source software they rely on most, and then allocate funds accordingly..."

The great libraries of the ancient classical world are "legendary... said to have contained stacks of texts," writes ScienceAlert. But from Rome to Constantinople, Athens to Alexandria, only one collection survived to the present day.

And here in 2024, "we can now start reading its contents." A worldwide competition to decipher the charred texts of the Villa of Papyri — an ancient Roman mansion destroyed by the eruption of Mount Vesuvius — has revealed a timeless infatuation with the pleasures of music, the color purple, and, of course, the zingy taste of capers. The so-called Vesuvius challenge was launched a few years ago by computer scientist Brent Seales at the University of Kentucky with support from Silicon Valley investors. The ongoing 'master plan' is to build on Seales' previous work and read all 1,800 or so charred papyri from the ancient Roman library, starting with scrolls labeled 1 to 4.

In 2023, the annual gold prize was awarded to a team of three students, who recovered four passages containing 140 characters — the longest extractions yet. The winners are Youssef Nader, Luke Farritor, and Julian Schilliger. "After 275 years, the ancient puzzle of the Herculaneum Papyri has been solved," reads the Vesuvius Challenge Scroll Prize website. "But the quest to uncover the secrets of the scrolls is just beginning...." Only now, with the advent of X-ray tomography and machine learning, can their inky words be pulled from the darkness of carbon.
A few months ago students deciphered a single word — "purple," according to the article. But "That winning code was then made available for all competitors to build upon." Within three months, passages in Latin and Greek were blooming from the blackness, almost as if by magic. The team with the most readable submission at the end of 2023 included both previous finders of the word 'purple'. Their unfurling of scroll 1 is truly impressive and includes more than 11 columns of text. Experts are now rushing to translate what has been found. So far, about 5 percent of the scroll has been unrolled and read to date. It is not a duplicate of past work, scholars of the Vesuvius Challenge say, but a "never-before-seen text from antiquity."

One line reads: "In the case of food, we do not right away believe things that are scarce to be absolutely more pleasant than those which are abundant."

"For nearly a year now, a bizarre heating event has been unfolding across the world's oceans," reports Wired.

"In March 2023, global sea surface temperatures started shattering record daily highs and have stayed that way since..." Brian McNoldy, a hurricane researcher at the University of Miami. "It's really getting to be strange that we're just seeing the records break by this much, and for this long...." Unlike land, which rapidly heats and cools as day turns to night and back again, it takes a lot to warm up an ocean that may be thousands of feet deep. So even an anomaly of mere fractions of a degree is significant. "To get into the two or three or four degrees, like it is in a few places, it's pretty exceptional," says McNoldy.

So what's going on here? For one, the oceans have been steadily warming over the decades, absorbing something like 90 percent of the extra heat that humans have added to the atmosphere...

A major concern with such warm surface temperatures is the health of the ecosystems floating there: phytoplankton that bloom by soaking up the sun's energy and the tiny zooplankton that feed on them. If temperatures get too high, certain species might suffer, shaking the foundations of the ocean food web. But more subtly, when the surface warms, it creates a cap of hot water, blocking the nutrients in colder waters below from mixing upwards. Phytoplankton need those nutrients to properly grow and sequester carbon, thus mitigating climate change...

Making matters worse, the warmer water gets, the less oxygen it can hold. "We have seen the growth of these oxygen minimum zones," says Dennis Hansell, an oceanographer and biogeochemist at the University of Miami. "Organisms that need a lot of oxygen, they're not too happy when the concentrations go down in any way — think of a tuna that is expending a lot of energy to race through the water."
But why is this happening? The article suggests less dust blowing from the Sahara desert to shade the oceans, but also 2020 regulations that reduced sulfur aerosols in shipping fuels. (This reduced toxic air pollution — but also some cloud cover.)

There was also an El Nino in the Pacific ocean last summer — now waning — which complicates things, according to biological oceanographer Francisco Chavez of the Monterey Bay Aquarium Research Institute in California. "One of our challenges is trying to tease out what these natural variations are doing in relation to the steady warming due to increasing CO2 in the atmosphere."

But the article points out that even the Atlantic ocean is heating up — and "sea surface temperatures started soaring last year well before El Niño formed." And last week the U.S. Climate Prediction Center predicted there's now a 55% chance of a La Nina in the Atlantic between June and August, according to the article — which could increase the likelihood of hurricanes.

Modern U.S. farming is being transformed by precision agriculture, writes Paul Roberts, the founder of securepairs.org and Editor in Chief at Security Ledger.

Theres autonomous tractors and "smart spraying" systems that use AI-powered cameras to identify weeds, just for starters. "Among the critical components of precision agriculture: Internet- and GPS connected agricultural equipment, highly accurate remote sensors, 'big data' analytics and cloud computing..." As with any technological revolution, however, there are both "winners" and "losers" in the emerging age of precision agriculture... Precision agriculture, once broadly adopted, promises to further reduce the need for human labor to run farms. (Autonomous equipment means you no longer even need drivers!) However, the risks it poses go well beyond a reduction in the agricultural work force. First, as the USDA notes on its website: the scale and high capital costs of precision agriculture technology tend to favor large, corporate producers over smaller farms. Then there are the systemic risks to U.S. agriculture of an increasingly connected and consolidated agriculture sector, with a few major OEMs having the ability to remotely control and manage vital equipment on millions of U.S. farms... (Listen to my podcast interview with the hacker Sick Codes, who reverse engineered a John Deere display to run the Doom video game for insights into the company's internal struggles with cybersecurity.)

Finally, there are the reams of valuable and proprietary environmental and operational data that farmers collect, store and leverage to squeeze the maximum productivity out of their land. For centuries, such information resided in farmers' heads, or on written or (more recently) digital records that they owned and controlled exclusively, typically passing that knowledge and data down to succeeding generation of farm owners. Precision agriculture technology greatly expands the scope, and granularity, of that data. But in doing so, it also wrests it from the farmer's control and shares it with equipment manufacturers and service providers — often without the explicit understanding of the farmers themselves, and almost always without monetary compensation to the farmer for the data itself. In fact, the Federal Government is so concerned about farm data they included a section (1619) on "information gathering" into the latest farm bill.

Over time, this massive transfer of knowledge from individual farmers or collectives to multinational corporations risks beggaring farmers by robbing them of one of their most vital assets: data, and turning them into little more than passive caretakers of automated equipment managed, controlled and accountable to distant corporate masters.
Weighing in is Kevin Kenney, a vocal advocate for the "right to repair" agricultural equipment (and also an alternative fuel systems engineer at Grassroots Energy LLC). In the interview, he warns about the dangers of tying repairs to factory-installed firmware, and argues that its the long-time farmer's "trade secrets" that are really being harvested today. The ultimate beneficiary could end up being the current "cabal" of tractor manufacturers.

"While we can all agree that it's coming...the question is who will own these robots?" First, we need to acknowledge that there are existing laws on the books which for whatever reason, are not being enforced. The FTC should immediately start an investigation into John Deere and the rest of the 'Tractor Cabal' to see to what extent farmers' farm data security and privacy are being compromised. This directly affects national food security because if thousands- or tens of thousands of tractors' are hacked and disabled or their data is lost, crops left to rot in the fields would lead to bare shelves at the grocery store... I think our universities have also been delinquent in grasping and warning farmers about the data-theft being perpetrated on farmers' operations throughout the United States and other countries by makers of precision agricultural equipment.

An anonymous reader shares a report: Applying to some of the most common customer and food service jobs in the country now requires a long and bizarre personality quiz featuring blue humanoid aliens, which tells employers how potential hires rank in terms of "agreeableness" and "emotional stability." If you've applied to a job at FedEx, McDonald's, or Darden Restaurants (the company that operates multiple chains including Olive Garden) you might have already encountered this quiz, as all these companies and others are clients of Paradox.ai, the company which runs the test and helps them with other recruiting tasks.

Judging by the reaction on Reddit, where Paradox.ai's personality quiz has gone viral a couple of times in recent weeks and bewildered many users, most people are not familiar with the process. Personality quizzes as part of an application for hourly work isn't new, but the Paradox.ai test has gone repeatedly viral in recent weeks presumably because of the bizarre scenarios it presents applicants with and the blue humanoid alien thing. Other clients included on Paradox's website include CVS, GM, Nestle, 3M, and Unilever.

An anonymous reader shared this report from the Associated Press: An abrupt shutdown of Atlantic Ocean currents that could put large parts of Europe in a deep freeze is looking a bit more likely and closer than before as a new complex computer simulation finds a "cliff-like" tipping point looming in the future. A long-worried nightmare scenario, triggered by Greenland's ice sheet melting from global warming, still is at least decades away if not longer, but maybe not the centuries that it once seemed, a new study in Friday's Science Advances finds.

The study, the first to use complex simulations and include multiple factors, uses a key measurement to track the strength of vital overall ocean circulation, which is slowing. A collapse of the current — called the Atlantic Meridional Overturning Circulation or AMOC — would change weather worldwide because it means a shutdown of one of key the climate and ocean forces of the planet. It would plunge northwestern European temperatures by 9 to 27 degrees (5 to 15 degrees Celsius) over the decades, extend Arctic ice much farther south, turn up the heat even more in the Southern Hemisphere, change global rainfall patterns and disrupt the Amazon, the study said. Other scientists said it would be a catastrophe that could cause worldwide food and water shortages.

"We are moving closer (to the collapse), but we we're not sure how much closer," said study lead author Rene van Westen, a climate scientist and oceanographer at Utrecht University in the Netherlands. "We are heading towards a tipping point." When this global weather calamity — grossly fictionalized in the movie "The Day After Tomorrow" — may happen is "the million-dollar question, which we unfortunately can't answer at the moment," van Westen said. He said it's likely a century away but still could happen in his lifetime. He just turned 30.

"It also depends on the rate of climate change we are inducing as humanity," van Westen said.

NASA's nearly $1 billion PACE mission launched atop a SpaceX Falcon 9 rocket early this morning, successfully making it to polar orbit -- a first for NASA since 1960. "When it's up and running, PACE will make key observations of Earth's atmosphere and climate and allow scientists to assess the health of our oceans like never before," notes Space.com. From the report: PACE, by the way, is the first U.S. government mission to launch to a polar orbit from Florida since Nov. 30, 1960. On that day, a Thor Able Star rocket took off on such a trajectory but failed, raining debris down on Cuba, some of which apparently killed a cow. Rather than risk further incidents, the U.S. decided to conduct all of its subsequent polar launches from Vandenberg Air Force Base (now Vandenberg Space Force Base) in California -- until now. That said, PACE wasn't the first mission of any type to launch to polar orbit from Florida's Space Coast in six decades: SpaceX had completed 11 such commercial missions before sending PACE on its way.

PACE's handlers will now work to get the 10.5-foot-long (3.2 meters) spacecraft and its various subsystems up to speed. After this checkout period, the satellite can begin its science work. That work will be done by three instruments. One of them, a spectrometer called the Ocean Color Instrument (OCI), will map out the ocean's many hues in great detail and an unprecedented range, from near-infrared wavelengths all way to the ultraviolet. These colors are determined by the interaction of sunlight with particles in seawater, such as the chlorophyll produced by photosynthetic plankton, the base of the marine food web. So OCI will reveal quite a bit about the health and status of ocean ecosystems, according to PACE team members.

"PACE's unprecedented spectral coverage will provide the first-ever global measurements designed to identify phytoplankton community composition," NASA officials wrote in a PACE mission description. "This will significantly improve our ability to understand Earth's changing marine ecosystems, manage natural resources such as fisheries and identify harmful algal blooms." The satellite's other two instruments are polarimeters. They'll measure how the oscillation of light in a plane, known as its polarization, is affected by passage through the ocean, clouds and aerosols (particles suspended in the atmosphere). "Measuring polarization states of UV-to-shortwave light at various angles provides detailed information on the atmosphere and ocean, such as particle size and composition," NASA officials wrote in the mission description.

In a first for Uber since becoming a public company, the ride-hailing service posted its first full-year profit and its stock hit an all-time high Wednesday. "Like its final year as a private company, the last time Uber turned a profit, it got a huge tailwind from investments that helped fuel profits, $1 billion in 2023," reports the Associated Press. "The difference is that Uber has started making money from operations." From the report: Uber and other ride-share companies struggled through the COVID-19 pandemic. The company, whose stock recently joined the S&P 500 index, saw its ride-hailing business stymied as government lockdowns kept millions at home. But Uber has focused on cutting costs and, during the pandemic, building up a then-nascent food-delivery division, which has since become a major revenue driver. Uber's ride-hailing service, meanwhile, has gradually bounced back and the numbers from the fourth quarter suggest both are trending in the right direction.

Delivery revenue grew 6%, and revenue for the ride-share part of the business climbed 34%. Industry analysts also noted growth in the company's membership platform. "Uber One now has roughly 19 million members across 25 countries, wrote William Blair's Ralph Schackart. "Uber One members generate roughly 30% of mobility and delivery gross bookings, up roughly 700 basis points year-over-year." Revenue totaled $9.94 billion, beating Wall Street projections for $9.75 billion. Gross bookings surged 22% from the prior-year period to $37.6 billion. For the year, Uber posted a profit of $1.89 billion, or 87 cents per share, on revenue of $37.28 billion.
