Google Finally Launches Android's 'Find My Device' Network (zdnet.com) 41

This week the new "Find My Device" feature rolled out to Android devices around the world, starting in the U.S. and Canada.

"With a new, crowdsourced network of over a billion Android devices, Find My Device can help you find your misplaced Android devices and everyday items quickly and securely," according to a Google blog post. ZDNet explains: Although Google already offers a Find My Device setting on Android phones, the device you're looking for must be powered on and connected for the feature to work. The new Find My Device network is designed to use Bluetooth to track down missing phones and other devices that are disconnected from a Wi-Fi or cellular network. A Powered Off Finding feature would let each device store beacons in its Bluetooth controller's memory, letting the network see any supported device even if it's not connected.
From Google's blog post: Locate your compatible Android phone and tablet by ringing them or viewing their location on a map in the app — even when they're offline. And thanks to specialized Pixel hardware, Pixel 8 and 8 Pro owners will also be able to find their devices if they're powered off or the battery is dead.

Starting in May, you'll be able to locate everyday items like your keys, wallet or luggage with Bluetooth tracker tags from Chipolo and Pebblebee in the Find My Device app.

Google promises "end-to-end encryption of location data as well as aggregated device location reporting, a first-of-its-kind safety feature that provides additional protection against unwanted tracking back to a home or private location." Find My Device is available on compatible devices running Android 9 or higher.

In addition, "Sometimes what we're looking for is right under our noses. If you're close to your lost device but need a little extra help tracking it down, a 'Find nearby' button will appear to help you figure out exactly where it's hiding. You'll also be able to use this to find everyday items, like your wallet or keys, when Bluetooth tags launch in May.

"More often than not, we lose everyday items like our keys or phone right at home. So the Find My Device app now shows a lost device's proximity to your home Nest devices, giving you an easy reference point."

NASA Figured Out Why Its Voyager 1 Probe Has Been Glitching for Months (gizmodo.com) 58

NASA engineers have traced the Voyager 1 spacecraft's transmitted gibberish to corrupted memory hardware in its flight data system (FDS). "The team suspects that a single chip responsible for storing part of the affected portion of the FDS memory isn't working," NASA wrote in an update. Gizmodo reports: FDS collects data from Voyager's science instruments, as well as engineering data about the health of the spacecraft, and combines them into a single package that's transmitted to Earth through one of the probe's subsystems, the telemetry modulation unit (TMU), in binary code. FDS and TMU have been having trouble communicating with one another. As a result, TMU has been sending data to mission control in a repeating pattern of ones and zeroes. NASA's engineers aren't quite sure what corrupted the FDS memory hardware; they think that either the chip was hit by an energetic particle from space or that it's just worn out after operating for 46 years. [...] The engineers are hoping to resolve the issue by finding a way for FDS to operate normally without the corrupted memory hardware, enabling Voyager 1 to begin transmitting data about the cosmos and continue its journey through deep space.

Traders Are Betting Millions That Trump Media 'Meme Stock' Will Tumble (nytimes.com) 151

Many investors are lining up to bet on the collapse of former President Donald J. Trump's social media company, Trump Media & Technology Group Corp., which made its stock market debut last week under the ticker "DJT." The stock has been called the "mother of all meme stocks" since it is highly volatile and there are no fundamental underpinnings. It's being valued at roughly 1,600 times its annual revenue, at Wednesday's closing price. "By comparison, the stock of Facebook's owner trades at about eight times revenues, and Google's owner trades at six times," notes Fast Company. The New York Times reports: Trump Media is the most "shorted" special purpose acquisition vehicle in the country, according to the financial data company S3 Partners. Short-sellers bet that the price of a stock will fall. They do that by borrowing shares of a company and selling them into the market, hoping to buy them back later at a lower price, before returning the shares to the lender and pocketing the difference as profit. The demand to short Trump Media, the parent company of the social media platform Truth Social, is so great that stock lenders can charge enormous fees, making it hard for short-sellers to turn a profit unless the shares fall significantly. Still, there is a lot of interest in taking the bet. "They are looking for this stock to crater and crater very quickly," said Ihor Dusaniwsky, managing director of predictive analytics at S3. Last month, traders lost $126 million betting against Trump Media, according to S3.

On Monday, Trump Media published updated financial information, revealing little revenue, large losses and a statement from the company's independent auditor expressing "substantial doubt" about its financial viability. This appeared to galvanize investors betting against the company, as the stock slipped from its highs. But short-sellers are finding it difficult and costly to trade in Trump Media. There are roughly 137 million shares in the company, and only around five million of those are available to short-sellers. Mr. Trump owns about 60 percent of shares, and company executives also hold a chunk of the stock. Company insiders tend not to lend their shares to short-sellers. Big asset managers like BlackRock, Vanguard and State Street, which regularly lend out shares, are not major holders of Trump Media, further crimping the supply.

According to S3, 4.9 million of the roughly five million available shares are already on loan. As with any loan, when share owners lend their stock to a short-seller, they charge a fee, usually expressed as an annual interest rate on the stock's current value. Typically, the fee for borrowing stock is a fraction of a percentage point. For Trump Media, it has risen to 550 percent, Mr. Dusaniwsky said. Trump Media's stock currently trades at around $50. That means that shorting it for a month would cost more than $20 per share. For a short-seller to break even, the stock price would have to fall by almost half by early May.

There is another wrinkle, too. One large broker said much of the short trading was not an outright bet against Trump Media. Since the advent of meme-stock trading and the vilification of short-sellers that win only if popular companies lose, large investors are wary of making such trades. Instead, the current trade driving demand is designed to capture the difference between DJT's stock price and outstanding "warrants," which will give the owners the right to new stock at a fixed price as long as regulators approve the new shares. Partly because of that uncertainty, those warrants currently trade below $19, with a list of hedge funds as recent holders. Even after the high cost to borrow stock is accounted for, they are still able to profit from the $30 difference between existing stock and what the warrants are worth, assuming the warrants become registered as shares.

Microsoft Edge Will Let You Control How Much RAM It Uses Soon (theverge.com) 62

Microsoft is working on a new feature for its Edge browser that will let you limit the amount of RAM it uses. From a report: Leopeva64, who is one of the best at finding new Edge features, has spotted a new settings section in test builds of the browser that includes a slider so you can limit how much RAM Edge gets access to. The RAM slider appears to be targeted toward PC gamers, as there is a setting in Canary versions of Edge that lets you limit the amount of RAM when you're playing a PC game or all of the time. While the slider lets you pick between just 1GB and 16GB on a system with 16GB of RAM, Microsoft warns that "setting a low limit may impact browser speed."

YouTube Inspires 'True Crime Junkies' to Buy Sonar-Equipped Boat and Solve Cold-Case Mysteries (tampabay.com) 35

Described as a "non profit volunteer search team" on its official site, Sunshine State Sonar "found more than 350 cars in canals, ponds and waterways across Florida" in just the last two years, according to the Tampa Bay Times.

It's owned by two half brothers — "weekend fishermen turned amateur underwater detectives." [T]he true-crime junkies dive into cold cases, searching for the disappeared. Sometimes, they choose the cases themselves, following threads online. Other times, law enforcement asks for their help.

They have discovered remains of 11 missing people inside cars, giving answers to relatives who had spent years agonizing. One family, who thought their mom had left them, learned that she had driven off the road. Relatives of a missing teacher suspected his girlfriend — then found out he had been submerged in a canal for three years. And the son of a young mother who thought she had been murdered was relieved when her death proved a watery accident...

"It all started with YouTube," [Mike] Sullivan says. "I kinda got obsessed." A couple of years ago, he got into bingeing Adventures with Purpose, videos of a volunteer dive team in Oregon that searches for missing people. "Florida has so much water!" he told his wife. "I really need to do this...."

He didn't know how to scuba dive. He'd never longed to float through crystal water or over schools of colorful fish. But he got certified so he could swim through muddy channels and search waterlogged crime scenes. He bought a shallow-draft boat and outboard motor, rigged it with the latest fish-finding technology: a Lowrance SideScan sonar, a DownScan imaging device and a Garmin LiveScope. The machines send sound waves pulsing through the water, then record them as they bounce back to create a blurry image on a monitor — like a sonogram... The equipment cost Sullivan $21,000. It took him a year to be able to interpret the images, to tell a rock from a Volkswagen.

The AI Boom is Sending Silicon Valley's Talent Wars To New Extremes (wsj.com) 26

Tech companies are serving up million-dollar-a-year compensation packages, accelerated stock-vesting schedules and offers to poach entire engineering teams to draw people with expertise and experience in the kind of generative AI that is powering ChatGPT and other humanlike bots. They are competing against each other and against startups vying to be the next big thing to unseat the giants. From a report: The offers stand out even by the industry's relatively lavish past standards of outsize pay and perks. And the current AI talent shortage stands out for another reason: It is happening as layoffs are continuing in other areas of tech and as companies have been reallocating resources to invest more in covering the enormous cost of developing AI technology.

"There is a secular shift in what talents we're going after," says Naveen Rao, head of Generative AI at Databricks. "We have a glut of people on one side and a shortage on the other." Databricks, a data storage and management startup, doesn't have a problem finding software engineers. But when it comes to candidates who have trained large language models, or LLMs, from scratch or can help solve vexing problems in AI, such as hallucinations, Rao says there might be only a couple of hundred people out there who are qualified.

Some of these hard-to-find, tier-one candidates can easily get total compensation packages of $1 million a year or more. Salespeople in AI are also in demand and hard to find. Selling at the beginning of a technology transition when things are changing rapidly requires a different skill set and depth of knowledge. Candidates with those skills are making around double what an enterprise software salesperson would. But that isn't the norm for most people working in AI, Rao says. For managerial roles in AI and machine learning, base-pay increases ranged from 5% to 11% from April 2022 to April 2023, according to a WTW survey of more than 1,500 employers. The base-pay increases of nonmanagerial roles ranged from 13% to 19% during the same period.

Scientists Turn To AI To Make Beer Taste Even Better 80

Researchers say they have used AI to make brews even better. From a report: Prof Kevin Verstrepen, of KU Leuven university, who led the research, said AI could help tease apart the complex relationships involved in human aroma perception. "Beer -- like most food products -- contains hundreds of different aroma molecules that get picked up by our tongue and nose, and our brain then integrates these into one picture. However, the compounds interact with each other, so how we perceive one depends also on the concentrations of the others," he said.

Writing in the journal Nature Communications, Verstrepen and his colleagues report how they analysed the chemical makeup of 250 commercial Belgian beers of 22 different styles including lagers, fruit beers, blonds, West Flanders ales, and non-alcoholic beers. Among the properties studied were alcohol content, pH, sugar concentration, and the presence and concentration of more than 200 different compounds involved in flavour -- such as esters that are produced by yeasts and terpenoids from hops, both of which are involved in creating fruity notes.

A tasting panel of 16 participants sampled and scored each of the 250 beers for 50 different attributes, such as hop flavours, sweetness, and acidity -- a process that took three years. The researchers also collected 180,000 reviews of different beers from the online consumer review platform RateBeer, finding that while appreciation of the brews was biased by features such as price meaning they differed from the tasting panel's ratings, the ratings and comments relating to other features -- such as bitterness, sweetness, alcohol and malt aroma -- these correlated well with those from the tasting panel.

93-Year-Old William Shatner Discusses 'Star Trek', Space, Mortality, and Captain Kirk's Death (theguardian.com) 62

"It was three years of my, life you know?" a 93-year-old William Shatner tells the Guardian when asked about playing Captain Kirk on the original Star Trek series from 1967 to 1969: It gladdens him to see how much joy the series has brought its many fans, but the richest rewards came in his introduction to science fiction, which activated and nurtured a lifelong curiosity about our species. He reminisces about meeting the great writers of the genre fondly yet frankly, honest enough to sort Ray Bradbury into "the category right below friend, I think". He devoured their novels and developed a fascination with the principle of defamiliarization, that concepts taken for granted can be understood anew when viewed through the vantage of a stranger in a strange land. "Good science fiction is humanity, moved into a different milieu," he says.
Even on a grander scale, "The universe charms him with its mysteries," writes the Guardian, calling it "the key to maintaining wonder through nearly a century of life. He likes the not-knowing."

You can see this at play when the TV starship captain became a real-life spacefarer in 2021: Liberated by weightlessness, he found himself utterly transformed by the rush of perspective one can only assume miles above the Earth. "It's very personal, what you see from up there, what you read into the stillness," he says. "I saw the blankness of space as death, but an astronaut will see something else entirely. And when I looked back at the Earth, I saw life."

The question of mortality hangs over Shatner, albeit not in a morbid way. He's entranced by the paradox of death, that the absolute unknowability of what happens will be inevitably supplanted by the certainty of finding out... For a man accustomed to boldly going where no man has gone before, it's all just the next phase of a single ongoing adventure.

In fact, Shatner told Jimmy Kimmel Friday that he was always disappointed by the way he'd performed Captain Kirk's death. "I think you die the way you live," Shatner says. "So Captain Kirk always had these grotesque things happening... but without fear. But with joy, and love, and an opportunity to see what's better." So when performing Kirk's death, he'd imagined him actually gazing upon death itself — and looking upon it with wonder. "I ad libbed the 'Oh my'." Shatner's regret? That it "sounded fearful. And I didn't want to be fearful."

"Would you like a do-over?" Kimmel asks. (Adding "I've got some debris...") And Shatner agrees, performing — one more time — the death of Captain Kirk.

The video also includes an appropriate clip from a newly-released documentary about Shatner's life. "Don't do it half-heartedly," Shatner says at one point. "Whatever it is you do — do it fully. Do it passionately. Do it with your whole being."

Pregnancy May Increase Biological Age 2 Years - But Some End Up 'Younger' (science.org) 29

Slashdot reader sciencehabit shared this report from Science magazine: Nurturing a growing fetus requires a series of profound physical, hormonal, and chemical changes that may rewire every major organ in the body and can cause serious health complications such as hypertension and preeclampsia. But does being pregnant actually take years off your life...?

Today in Cell Metabolism, scientists report that the stress of pregnancy can cause a person's biological age to increase by up to 2 years — a trend that may reverse itself in the months that follow. In some cases, the authors write, those who breastfeed their children after giving birth may end up biologically "younger" than during early pregnancy. The finding represents yet another piece of "compelling" evidence that events during and after pregnancy can have far-reaching health consequences, says Elizabeth Bertone-Johnson, an epidemiologist at the University of Massachusetts Amherst who wasn't involved in the new study...

The discovery that biological aging isn't necessarily a linear process "came as a real surprise," says Kieran O'Donnell, a perinatal researcher at the Yale School of Medicine... But blood samples from 68 participants, collected 3 months after giving birth, revealed a dramatic about-face. Although being pregnant had initially aged their cells between 1 and 2 years, says O'Donnell, their biological age now appeared to be 3 to 8 years younger than it had been during early pregnancy — with different epigenetic clocks algorithms providing slightly bigger or smaller estimates.

Truck-To-Truck Worm Could Infect Entire US Fleet (theregister.com) 50

Jessica Lyons reports via The Register: Vulnerabilities in common Electronic Logging Devices (ELDs) required in US commercial trucks could be present in over 14 million medium- and heavy-duty rigs, according to boffins at Colorado State University. In a paper presented at the 2024 Network and Distributed System Security Symposium, associate professor Jeremy Daily and systems engineering graduate students Jake Jepson and Rik Chatterjee demonstrated how ELDs can be accessed over Bluetooth or Wi-Fi connections to take control of a truck, manipulate data, and spread malware between vehicles. "These findings highlight an urgent need to improve the security posture in ELD systems," the trio wrote [PDF].

The authors did not specify brands or models of ELDs that are vulnerable to the security flaws they highlight in the paper. But they do note there's not too much diversity of products on the market. While there are some 880 devices registered, "only a few tens of distinct ELD models" have hit the road in commercial trucks. A federal mandate requires most heavy-duty trucks to be equipped with ELDs, which track driving hours. These systems also log data on engine operation, vehicle movement and distances driven -- but they aren't required to have tested safety controls built in. And according to the researchers, they can be wirelessly manipulated by another car on the road to, for example, force a truck to pull over.

The academics pointed out three vulnerabilities in ELDs. They used bench level testing systems for the demo, as well as additional testing on a moving 2014 Kenworth T270 Class 6 research truck equipped with a vulnerable ELD. [...] For one of the attacks, the boffins showed how anyone within wireless range could use the device's Wi-Fi and Bluetooth radios to send an arbitrary CAN message that could disrupt of some of the vehicle's systems. A second attack scenario, which also required the attacker to be within wireless range, involved connecting to the device and uploading malicious firmware to manipulate data and vehicle operations. Finally, in what the authors described as the "most concerning" scenario, they uploaded a truck-to-truck worm. The worm uses the compromised device's Wi-Fi capabilities to search for other vulnerable ELDs nearby. After finding the right ELDs, the worm uses default credentials to establish a connection, drops its malicious code on the next ELD, overwrites existing firmware, and then starts the process over again, scanning for additional devices. "Such an attack could lead to widespread disruptions in commercial fleets, with severe safety and operational implications," the researchers warned.

Superconductor Scientist Engaged in Research Misconduct, Probe Finds (wsj.com) 22

A physicist who shot to fame with claims of the discovery of a room-temperature superconductor engaged in research misconduct, a committee tapped to examine his work has concluded after a monthslong investigation. From a report: Ranga Dias, a physicist at the University of Rochester in New York, has had at least four papers he co-wrote, including three involving superconductivity, retracted in the past 18 months by the journals that published them. A committee of outside experts tapped by the university "identified data-reliability concerns in those papers," a Rochester spokesperson told The Wall Street Journal. "The committee concluded, in accordance with university policy and federal regulations, that Dias engaged in research misconduct," the spokesperson said in an emailed statement.

The work in the papers was funded by the National Science Foundation, the Energy Department, and the Gordon and Betty Moore Foundation, a private organization that funds scientific research. The Moore foundation discontinued its grant late last year, the organization said. Of the $1.6 million award, about $285,000 was spent. The university refunded the rest. The investigation follows three preliminary reviews by the university of one of the studies, published in Nature in 2020 and retracted in 2022 after criticism from other scientists. Those inquiries didn't find enough evidence to prompt a full investigation. Complaints sent to the university in spring 2023 about additional studies prompted a more thorough review. That investigation was completed by March this year, resulting in the misconduct finding. The journal Nature reported earlier this month that this investigation was complete.

Only Seven Countries Meet WHO Air Quality Standard, Research Finds (theguardian.com) 56

An anonymous reader quotes a report from The Guardian: Only seven countries are meeting an international air quality standard, with deadly air pollution worsening in places due to a rebound in economic activity and the toxic impact of wildfire smoke, a new report has found. Of 134 countries and regions surveyed in the report, only seven -- Australia, Estonia, Finland, Grenada, Iceland, Mauritius and New Zealand -- are meeting a World Health Organization (WHO) guideline limit for tiny airborne particles expelled by cars, trucks and industrial processes. The vast majority of countries are failing to meet this standard for PM2.5, a type of microscopic speck of soot less than the width of a human hair that when inhaled can cause a myriad of health problems and deaths, risking serious implications for people, according to the report by IQAir, a Swiss air quality organization that draws data from more than 30,000 monitoring stations around the world.

While the world's air is generally much cleaner than it was in much of the past century, there are still places where the pollution levels are particularly dangerous. The most polluted country, Pakistan, has PM2.5 levels more than 14 times higher than the WHO standard, the IQAir report found, with India, Tajikistan and Burkina Faso the next most polluted countries. But even in wealthy and fast-developing countries, progress in cutting air pollution is under threat. Canada, long considered as having some of the cleanest air in the western world, became the worst for PM2.5 last year due to record wildfires that ravaged the country, sending toxic spoke spewing across the country and into the US. In China, meanwhile, improvements in air quality were complicated last year by a rebound in economic activity in the wake of the Covid-19 pandemic, with the report finding a 6.5% increase in PM2.5 levels.

The most polluted urban area in the world last year was Begusarai in India, the sixth annual IQAir report found, with India home to the four most polluted cities in the world. Much of the developing world, particularly countries in Africa, lacks reliable air quality measurements, however. The WHO lowered its guideline for "safe" PM2.5 levels in 2021 to five micrograms per cubic meter and by this measure many countries, such as those in Europe that have cleaned up their air significantly in the past 20 years, fall short. But even this more stringent guideline may not fully capture the risk of insidious air pollution. Research released by US scientists last month found there is no safe level of PM2.5, with even the smallest exposures linked to an increase in hospitalizations for conditions such as heart disease and asthma.

Modern Web Bloat Means Some Pages Load 21MB of Data (tomshardware.com) 110

Christopher Harper reports via Tom's Hardware: Earlier this month, Danluu.com released an exhaustive 23-page analysis/op-ed/manifesto on the current status of unoptimized web pages and web app performance, finding that just loading a web page can even bog down an entry-level device that can run the popular game PUBG at 40 fps. In fact, the Wix webpage requires loading 21MB of data for one page, while the more famous websites Patreon and Threads load 13MB of data for one page. This can result in slow load times that reach up to 33 seconds or, in some cases, result in the page failing to load at all.

As the testing above shows, some of the most brutally intensive websites include the likes of... Quora, and basically every major social media platform. Newer content production platforms like Squarespace and newer Forum platforms like Discourse also have significantly worse performance than their older counterparts, often to the point of unusability on some devices. The Tecno S8C, one of the prominent entry-level phones common in emerging markets, is one particularly compelling test device that stuck. The device is actually quite impressive in some ways, including its ability to run PlayerUnknown's Battlegrounds Mobile at 40 FPS -- but the same device can't even run Quora and experiences nigh-unusable lag when scrolling on social media sites.

That example is most likely the best summation of the overall point, which is that modern web and app design is increasingly trending toward an unrealistic assumption of ever-increasing bandwidth and processing. Quora is a website where people answer questions -- there is absolutely no reason any of these websites should be harder to run than a Battle Royale game.

Why Are So Many AI Chatbots 'Dumb as Rocks'? (msn.com) 73

Amazon announced a new AI-powered chatbot last month — still under development — "to help you figure out what to buy," writes the Washington Post. Their conclusion? "[T]he chatbot wasn't a disaster. But I also found it mostly useless..."

"The experience encapsulated my exasperation with new types of AI sprouting in seemingly every technology you use. If these chatbots are supposed to be magical, why are so many of them dumb as rocks?" I thought the shopping bot was at best a slight upgrade on searching Amazon, Google or news articles for product recommendations... Amazon's chatbot doesn't deliver on the promise of finding the best product for your needs or getting you started on a new hobby.

In one of my tests, I asked what I needed to start composting at home. Depending on how I phrased the question, the Amazon bot several times offered basic suggestions that I could find in a how-to article and didn't recommend specific products... When I clicked the suggestions the bot offered for a kitchen compost bin, I was dumped into a zillion options for countertop compost products. Not helpful... Still, when the Amazon bot responded to my questions, I usually couldn't tell why the suggested products were considered the right ones for me. Or, I didn't feel I could trust the chatbot's recommendations.

I asked a few similar questions about the best cycling gloves to keep my hands warm in winter. In one search, a pair that the bot recommended were short-fingered cycling gloves intended for warm weather. In another search, the bot recommended a pair that the manufacturer indicated was for cool temperatures, not frigid winter, or to wear as a layer under warmer gloves... I did find the Amazon chatbot helpful for specific questions about a product, such as whether a particular watch was waterproof or the battery life of a wireless keyboard.

But there's a larger question about whether technology can truly handle this human-interfacing task. "I have also found that other AI chatbots, including those from ChatGPT, Microsoft and Google, are at best hit-or-miss with shopping-related questions..." These AI technologies have potentially profound applications and are rapidly improving. Some people are making productive use of AI chatbots today. (I mostly found helpful Amazon's relatively new AI-generated summaries of customer product reviews.)

But many of these chatbots require you to know exactly how to speak to them, are useless for factual information, constantly make up stuff and in many cases aren't much of an improvement on existing technologies like an app, news articles, Google or Wikipedia. How many times do you need to scream at a wrong math answer from a chatbot, botch your taxes with a TurboTax AI, feel disappointed at a ChatGPT answer or grow bored with a pointless Tom Brady chatbot before we say: What is all this AI junk for...?

"When so many AI chatbots overpromise and underdeliver, it's a tax on your time, your attention and potentially your money," the article concludes.

"I just can't with all these AI junk bots that demand a lot of us and give so little in return."

Playing Thriving Reef Sounds On Underwater Speakers 'Could Save Damaged Corals' 31

An anonymous reader quotes a report from The Guardian: Underwater speakers that broadcast the hustle and bustle of thriving coral could bring life back to more damaged and degraded reefs that are in danger of becoming ocean graveyards, researchers say. Scientists working off the US Virgin Islands in the Caribbean found that coral larvae were up to seven times more likely to settle at a struggling reef where they played recordings of the snaps, groans, grunts and scratches that form the symphony of a healthy ecosystem. "We're hoping this may be something we can combine with other efforts to put the good stuff back on the reef," said Nadeege Aoki at the Woods Hole Oceanographic Institution in Massachusetts. "You could leave a speaker out for a certain amount of time and it could be attracting not just coral larvae but fish back to the reef."

The world has lost half its coral reefs since the 1950s through the devastating impact of global heating, overfishing, pollution, habitat loss and outbreaks of disease. The hefty declines have fueled efforts to protect remaining reefs through approaches that range from replanting with nursery-raised corals to developing resilient strains that can withstand warming waters. Aoki and her colleagues took another tack, building on previous research which showed that coral larvae swim towards reef sounds. They set up underwater speakers at three reefs off St John, the smallest of the US Virgin Islands, and measured how many coral larvae, held in sealed containers of filtered sea water, settled on to pieces of rock-like ceramic in the containers up to 30 meters from the speakers.

While the researchers installed speakers at all three sites, they only played sounds from a thriving reef at one: the degraded Salt Pond reef, which was bathed in the marine soundscape for three nights. The other two sites, the degraded Cocoloba and the healthier Tektite reefs were included for comparison. When coral larvae are released into the water column they are carried on the currents, and swim freely, before finding a spot to settle. Once they drop to the ocean floor, they become fixed to the spot and -- if they survive -- mature into adults. Writing in the Royal Society Open Science journal, the researchers describe how, on average, 1.7 times more coral larvae settled at the Salt Pond reef than at the other sites where no reef sounds were played. The settlement rates at Salt Pond dropped with distance from the speaker, suggesting the broadcasts were responsible. While the results are promising, Aoki said more work is afoot to understand whether other coral species respond to reef sounds in the same way, and whether the corals thrive after settling.
"You have to be very thoughtful about the application of this technology," Aoki added. "You don't want to encourage them to settle where they will die. It really has to be a multi-pronged effort with steps in place to ensure the survival of these corals and their growth over time."

Cognition Emerges From Stealth To Launch AI Software Engineer 'Devin' (venturebeat.com) 95

Longtime Slashdot reader ahbond shares a report from VentureBeat: Today, Cognition, a recently formed AI startup backed by Peter Thiel's Founders Fund and tech industry leaders including former Twitter executive Elad Gil and Doordash co-founder Tony Xu, announced a fully autonomous AI software engineer called "Devin." While there are multiple coding assistants out there, including the famous Github Copilot, Devin is said to stand out from the crowd with its ability to handle entire development projects end-to-end, right from writing the code and fixing the bugs associated with it to final execution. This is the first offering of this kind and even capable of handling projects on Upwork, the startup has demonstrated. [...]

In a blog post today on Cognition's website, Scott Wu, the founder and CEO of Cognition and an award-winning sports coder, explained Devin can access common developer tools, including its own shell, code editor and browser, within a sandboxed compute environment to plan and execute complex engineering tasks requiring thousands of decisions. The human user simply types a natural language prompt into Devin's chatbot style interface, and the AI software engineer takes it from there, developing a detailed, step-by-step plan to tackle the problem. It then begins the project using its developer tools, just like how a human would use them, writing its own code, fixing issues, testing and reporting on its progress in real-time, allowing the user to keep an eye on everything as it works. [...]

According to demos shared by Wu, Devin is capable of handling a range of tasks in its current form. This includes common engineering projects like deploying and improving apps/websites end-to-end and finding and fixing bugs in codebases to more complex things like setting up fine-tuning for a large language model using the link to a research repository on GitHub or learning how to use unfamiliar technologies. In one case, it learned from a blog post how to run the code to produce images with concealed messages. Meanwhile, in another, it handled an Upwork project to run a computer vision model by writing and debugging the code for it. In the SWE-bench test, which challenges AI assistants with GitHub issues from real-world open-source projects, the AI software engineer was able to correctly resolve 13.86% of the cases end-to-end -- without any assistance from humans. In comparison, Claude 2 could resolve just 4.80% while SWE-Llama-13b and GPT-4 could handle 3.97% and 1.74% of the issues, respectively. All these models even required assistance, where they were told which file had to be fixed.

"The Doom of Man is at hand," captions Slashdot reader ahbond. "It will start with the low-hanging Jira tickets, and in a year or two, able to handle 99% of them. In the short term, software engineers may become like bot farmers, herding 10-1000 bots writing code, etc. Welcome to the future."

Ageism Haunts Some Tech Workers In the Race To Get Hired (wired.com) 67

An anonymous reader shares an excerpt from a Wired article: The U.S. economy is showing remarkable health, but in the tech industry, layoffs keep coming. For those out of work, finding a new position can become a full-time job. And in tech -- a sector notoriously always looking for the next hot, new thing -- some people whose days as fresh-faced coders are long gone say that having decades of experience can feel like a disadvantage. Ageism is a longtime problem in the tech industry. Database startup RelevantDB went viral in 2021 after it posted a job listing bragging, "We hire old people," which played off industry stereotypes. In 2020, the US Equal Employment Opportunity Commission found that IBMhad engaged in age discrimination, pushing out older workers to make room for younger ones. (The company has denied engaging in "systemic age discrimination.") A recent LinkedIn ad that shows an older woman unfamiliar with tech jargon saying her son sells invisible clouds triggered a backlash from people who say it unfairly portrayed older people as out of touch. In response, Jim Habig, LinkedIn's vice president of marketing, says: "This ad didn't meet our goal to create experiences where all professionals feel welcomed and valued, and we are working to replace the spot." [...]

Tech companies have laid off more than 400,000 workers over the past two years, according to Layoffs.fyi, which tracks job cuts in the industry. To older workers, the purge is both a reminder of the dotcom bust, and a new frontier. The industry's generally consistent growth in recent decades as the economy has become more tech-centric means that many more senior workers -- which in tech can sometimes be considered to mean over 35 but includes people in their late forties, fifties, or sixties -- may have less experience with job hunting. For decades, tech workers could easily hop between jobs in their networks, often poached by recruiters. And as tech companies boomed during the Covid-19 pandemic's early days, increased demand for skills gave workers leverage. Now the power has shifted to the employers as companies seek to become efficient and correct that over hiring phase, and applicants are hitting walls. Workers have to network, stay active on LinkedIn, join message boards, and stand out. With four generations now clocking in to work, things can feel crowded.

Google Paid $10 Million In Bug Bounty Rewards Last Year (bleepingcomputer.com) 17

Bill Toulas reports via BleepingComputer: Google awarded $10 million to 632 researchers from 68 countries in 2023 for finding and responsibly reporting security flaws in the company's products and services. Though this is lower than the $12 million Google's Vulnerability Reward Program paid to researchers in 2022, the amount is still significant, showcasing a high level of community participation in Google's security efforts.

The highest reward for a vulnerability report in 2023 was $113,337, while the total tally since the program's launch in 2010 has reached $59 million. For Android, the world's most popular and widely used mobile operating system, the program awarded over $3.4 million. Google also increased the maximum reward amount for critical vulnerabilities concerning Android to $15,000, driving increased community reports. During security conferences like ESCAL8 and hardwea.io, Google awarded $70,000 for 20 critical discoveries in Wear OS and Android Automotive OS and another $116,000 for 50 reports concerning issues in Nest, Fitbit, and Wearables. Google's other big software project, the Chrome browser, was the subject of 359 security bug reports that paid out a total of $2.1 million.

Airbnb is Banning Indoor Security Cameras (theverge.com) 103

Airbnb will no longer allow hosts to use indoor security cameras, regardless of where they're placed or what they're used for. In an update on Monday, Airbnb says the change to "prioritize the privacy" of renters goes into effect on April 30th. From a report: The vacation rental app previously let hosts install security cameras in "common areas" of listings, including hallways, living rooms, and front doors. Airbnb required hosts to disclose the presence of security cameras in their listings and make them clearly visible, and it prohibited hosts from using cameras in bedrooms and bathrooms.

But now, hosts can't use indoor security cameras at all. The change comes after numerous reports of guests finding hidden cameras within their rental, leading some vacation-goers to scan their rooms for cameras. Airbnb's new policy also introduces new rules for outdoor security cameras, and will now require hosts to disclose their use and locations before guests book a listing. Hosts can't use outdoor cams to keep tabs on indoor spaces, either, nor can they use them in "certain outdoor areas where there's a great expectation of privacy," such as an outdoor shower or sauna.

10 Years On, Is the World Any Closer To Finding MH370? (cnn.com) 90

An anonymous reader shares a report: For the past 10 years it has remained one of the modern era's greatest mysteries. A commercial airliner with a strong safety record carrying 239 people vanishing from the map, spawning a wide variety of competing theories, books and documentaries and leaving the families of those left behind asking themselves every March 8 -- what happened to those aboard Malaysia Airlines flight 370?

In an era when black boxes have been successfully hauled up from the very depths of the ocean and whole chunks of a downed airliner painstakingly pieced back together to determine what caused a catastrophe, the fate of MH370 remains infuriatingly elusive. It is a plane crash without a plane. A disaster without conclusive proof of what happened to its victims. A story that anyone who embarks on a commercial flight can instantly relate to but one that, for now at least, doesn't have a closing chapter.

[...] This week, many loved ones of those missing returned to Malaysia to urge local authorities to relaunch a search ahead of Friday's anniversary. [...] Aviation experts tell CNN that improved detection technology will likely bring families closer to the missing plane than they ever have been, if a search were to be relaunched. But that will not be cheap. Hundreds of millions of dollars were spent scouring more than 710,000 square kilometers of the Indian Ocean until 2018, but nothing transpired that moved our understanding on from that already available since the very early days.
