An anonymous reader shares a report: If you bought a new smart TV during any of the holiday sales, there’s likely to be an uninvited guest watching along with you. The most popular smart TVs sold today use automatic content recognition (ACR), a kind of ad surveillance technology that collects data on everything you view and sends it to a proprietary database to identify what you’re watching and serve you highly targeted ads. The software is largely hidden from view, and it’s complicated to opt out. Many consumers aren’t aware of ACR, let alone that it’s active on their shiny new TVs. If that’s you, and you’d like to turn it off, we’re going to show you how.

First, a quick primer on the tech: ACR identifies what’s displayed on your television, including content served through a cable TV box, streaming service, or game console, by continuously grabbing screenshots and comparing them to a massive database of media and advertisements. Think of it as a Shazam-like service constantly running in the background while your TV is on.

These TVs can capture and identify 7,200 images per hour, or approximately two every second. The data is then used for content recommendations and ad targeting, which is a huge business; advertisers spent an estimated $18.6 billion on smart TV ads in 2022, according to market research firm eMarketer. For anyone who’d rather not have ACR looking over their shoulder while they watch, we’ve put together a guide to turning it off on three of the most popular smart TV software platforms in use last year. Depending on the platform, turning off ACR took us between 10 and 37 clicks.

Apple is set to be hit by a ban on its App Store rules that govern music-streaming rivals and a potential hefty fine in the European Union’s latest attempt to limit the power of Big Tech. From a report: EU regulators are putting the finishing touches to a decision that would prohibit Apple’s practice of blocking music services from pushing their users away from the App Store to alternative subscription options, according to people familiar with the investigation. The decision is slated for early next year, they added. As part of the upcoming decision, Apple runs the risk of a potential fine of as much as 10% of its annual sales — although EU penalties seldom reach that level and orders for companies to change their business models can be more hard-hitting.

Google’s making the second generation of Imagen, its AI model that can create and edit images given a text prompt, more widely available — at least to Google Cloud customers using Vertex AI who’ve been approved for access. From a report: But the company isn’t disclosing which data it used to train the new model — nor introducing a way for creators who might’ve inadvertently contributed to the data set to opt out or apply for compensation.

Called Imagen 2, Google’s enhanced model — which was quietly launched in preview at the tech giant’s I/O conference in May — was developed using technology from Google DeepMind, Google’s flagship AI lab. Compared to the first-gen Imagen, it’s “significantly” improved in terms of image quality, Google claims (the company bizarrely refused to share image samples prior to this morning), and introduces new capabilities including the ability to render text and logos. “If you want to create images with a text overlay — for example, advertising — you can do that,” Google Cloud CEO Thomas Kurian said during a press briefing on Tuesday.

More than 190 governments at the United Nations climate conference approved an agreement Wednesday calling for the world to transition away from fossil fuels, an accord that bridged differences between big energy-producing nations and countries that want to completely phase out coal, oil and natural gas. From a report: The deal, the result of all-night talks, calls for “transitioning away from fossil fuels in energy systems, in a just, orderly and equitable manner.” It says the shift to clean energy for the global economy should accelerate this decade with the aim of net-zero greenhouse gas emissions by 2050.

Scientists say that is crucial to fulfilling the Paris accord, the landmark climate agreement that calls for governments to attempt to limit global warming to 1.5 degrees Celsius above preindustrial temperatures. The deal marks the first time a U.N. climate agreement has called for governments to cut back on all fossil fuels.

Regulators in the UK are weighing a cap on some of the fees that Visa and Mastercard charge local merchants for each card transaction, seeking to rein in charges that have risen fivefold since Brexit. From a report: After a monthslong review, the UK’s Payment Systems Regulator said it’s concerned that the payment giants have no effective competition, especially when it comes to the interchange fees they charge UK merchants when a consumer carrying a card issued by a bank in the European Economic Area makes an online purchase.

For now, the PSR is proposing to restore those fees to the pre-Brexit levels of 0.3% of a purchase price for credit cards and 0.2% for debit cards. For credit cards, those fees have risen in recent years to as high as 1.5% and the PSR estimated that the increases cost UK businesses as much as $250 million last year. The two companies have been under fire from a bevy of regulators and lawmakers around the world for the fees they charge. While it usually amounts to just pennies per purchase, the fees do add up: US merchants spent a record $160.7 billion on swipe fees last year, up 16.7% from 2021, according to the Nilson Report, an industry publication.

An anonymous reader quotes a report from The Register: Two years after the Log4Shell vulnerability in the open source Java-based Log4j logging utility was disclosed, circa one in four applications are dependent on outdated libraries, leaving them open to exploitation. Research from security shop Veracode revealed that the vast majority of vulnerable apps may never have updated the Log4j library after it was implemented by developers as 32 percent were running pre-2015 EOL versions. Prior investigations from Veracode also showed that 79 percent of all developers never update third-party libraries after first introducing them into projects, and given that Log4j2 — the specific version of Log4j affected by the vulnerability — dates back to 2014, this could explain the large proportion of unpatched apps.

A far smaller minority are running versions that were vulnerable at the time of the Log4j vulnerability’s disclosure in December 2021. Only 2.8 percent are still using versions 2.0-beta9 through 2.15.0 — post-EOL versions that remain exposed to Log4Shell, the industry-coined moniker of the vulnerability’s exploit. Some 3.8 percent are still running version 2.17, a post-patch version of the Java logger that’s not exposed to Log4Shell attacks, but is vulnerable to a separate remote code execution (RCE) bug (CVE-2021-44832).

The researchers believe this illustrates a minority of developers that acted quickly when the vulnerability was first disclosed, as was the advice at the time, had returned to older habits of leaving libraries untouched. Altogether, just shy of 35 percent remain vulnerable to Log4Shell, and nearly 40 percent are vulnerable to RCE flaws. The EOL versions of Log4j are also vulnerable to three additional critical bugs announced by Apache, bringing the total to seven high and critical-rated issues. “At a surface level, the numbers above show that the massive effort to remediate the Log4Shell vulnerability was effective in mitigating risk of exploitation of the zero-day vulnerability. That should not be surprising,” said Chris Eng, chief research officer at Veracode.

“The bigger story at the two-year anniversary, however, is that there is still room for improvement when it comes to open source software security. If Log4Shell was another example in a long series of wake-up calls to adopt more stringent open source security practices, the fact that more than one in three applications currently run vulnerable versions of Log4j shows there is more work to do.

“The major takeaway here is that organizations may not be aware of how much open source security risk they are exposed to and how to mitigate it.”

Despite being valued at $86 billion by private investors, OpenAI reported $44,485 in revenue in 2022, almost entirely from investment income. CNBC reports: That’s from the nonprofit parent’s 990 filing with the Internal Revenue Service, a form that has to be filled out by organizations wishing to maintain their tax-exempt status. Federal standards don’t require audited financial statements from nonprofits. In its home state of California, OpenAI was able to avoid submitting audited financials for 2022 because the foundation’s stated revenue was below the $2 million reporting threshold. The last time OpenAI filed with the state was 2017, when revenue was $33.2 million, or more than 700 times what the foundation reported for 2022.

For all its talk of openness, OpenAI’s financials remain a black box. Created as a nonprofit in 2015, OpenAI launched a so-called capped-profit entity in 2019, enabling it to raise billions of dollars in outside funding and attain attributes of a tech startup, such as the ability to hand out equity to employees. The for-profit side of the house went on to develop ChatGPT, the chatbot that took the world by storm late last year and kicked off the generative AI boom. […]

Thad Calabrese, a professor of public and nonprofit financial management at New York University, said OpenAI’s current status is confusing, and is unlike anything he has seen in the nonprofit world. He said OpenAI could give up its nonprofit status, and he cited the Blue Cross Blue Shield Association, which in 1994 allowed associated nonprofit medical insurance plans to switch into for-profit entities. “There’s no real need to have the nonprofit,” Calabrese said. “If you want to be a startup, be a startup.” Regarding OpenAI’s reporting with the IRS, he said “fundamentally you can’t really get a holistic sense of these organizations when you don’t have consolidated financial statements.”

For the first time, scientists have discovered nuclear fission occurring amongst the stars, supporting the idea that neutron stars create “superheavy” elements when they collide, which then break down via nuclear fission to birth rare elements. Space.com reports: Nuclear fission is basically the opposite of nuclear fusion. While nuclear fusion refers to the smashing of lighter elements to create heavier elements, nuclear fission is a process that sees energy released when heavy elements split apart to create lighter elements. Nuclear fission is pretty well known, too. It’s actually the basis of energy-generating nuclear power plants here on Earth — however, it had not been seen occurring amongst the stars before now.

The team of researchers led by North Carolina State University scientist Ian Roederer searched data concerning a wide range of elements in stars to discover the first evidence that nuclear fission could therefore be acting when neutron stars merge. These findings could help solve the mystery of where the universe’s heavy elements come from. Scientists know that nuclear fusion is not just the primary source of energy for stars, but also the force that forges a variety of elements, the “heaviest” being iron.

The evidence of nuclear fission discovered by [Matthew Mumpower, research co-author and a scientist at Los Alamos National Laboratory] and the team comes in the form of a correlation between “light precision metals,” like silver, and “rare earth nuclei,” like europium, showing in some stars. When one of these groups of elements goes up, the corresponding elements in the other group also increases, the scientists saw. The team’s research also indicates that elements with atomic masses — counts of protons and neutrons in an atomic nucleus — greater than 260 may exist around neutron star smashes, even if this existence is brief. This is much heavier than many of the elements at the “heavy end” of the periodic table. “The only plausible way this can arise among different stars is if there is a consistent process operating during the formation of the heavy elements,” Mumpower said. “This is incredibly profound and is the first evidence of fission operating in the cosmos, confirming a theory we proposed several years ago.”

“As we’ve acquired more observations, the cosmos is saying, ‘hey, there’s a signature here, and it can only come from fission.'”

The research was published in the journal Science.

An anonymous reader quotes a report from REVE News: The U.S. Energy Information Administration (EIA) expects, for the first year on record, combined electricity generation from wind and solar to surpass generation from coal in 2024. EIA expects solar generation in 2024 to increase 39% (228 kilowatthours) from 2023, driven by continued increases in solar capacity. “Renewables, particularly solar photovoltaics, are growing rapidly and making large contributions to electricity generation,” DeCarolis said.

EIA expects natural gas prices to be $2.77 per million British thermal units this winter, about 23% lower than previously forecast. The winter season is off to a warmer-than-expected start, so U.S. households are consuming less natural gas for heat than expected. The lower natural gas consumption is also contributing to rising U.S. natural gas inventories, which typically results in lower prices. “We’re seeing record domestic natural gas production paired with lower-than-expected natural gas demand, and we expect that is going to push prices lower this winter season,” DeCarolis said. EIA will publish its next STEO on January 9, 2024, including the agency’s first forecasts for the energy sector through 2025. The full report is available on the EIA website.

An artificial intelligence campaign volunteer named Ashley is being used to call thousands of Pennsylvania voters on behalf of Democrat Shamaine Daniels, “ushering in a new era of political campaigning in which candidates use technology to engage with voters in ways increasingly difficult to track,” reports Reuters. From the report: Like a seasoned campaign volunteer, Ashley analyzes voters’ profiles to tailor conversations around their key issues. Unlike a human, Ashley always shows up for the job, has perfect recall of all of Daniels’ positions, and does not feel dejected when she’s hung up on. “This is going to scale fast,” said 30-year-old Ilya Mouzykantskii, the London-based CEO of Civox, the company behind Ashley. “We intend to be making tens of thousands of calls a day by the end of the year and into the six digits pretty soon. This is coming for the 2024 election and it’s coming in a very big way. … The future is now.” For Daniels, the tool levels the playing field: as the underdog, she is now armed with another way to understand voters better, reach out in different languages (Ashley is fluent in over 20), and conduct many more “high bandwidth” conversations.

Mouzykantskii said he is fully aware of the potential downsides, and does not intend to take any venture capital funding which might entice him to prioritize profits over ethics. Mouzykantskii and his co-founder Adam Reis, former computer science students at Stanford and Columbia Universities respectively, declined to disclose the exact generative AI models they are using. They will only say they use over 20 different AI models, some proprietary and some open-source. Thanks to the latest generative AI technologies, Reis was able to build the product almost entirely on his own, whereas several years ago it would have taken a team of 50 engineers several years to do so, he said. The report notes that there are “few legal guardrails” regulating this particular use of AI. “No rules directly apply to what Civox is doing. Federal Trade Commission regulations ban telemarketers from making robocalls to people on the Do Not Call Registry, but the list does not apply to political calls — and Civox’s activity, with its ‘personalized’ messages, does not qualify as robocalling.”

For the first time, Netflix has released a comprehensive report of what people watched on the platform over a six month period. It includes hours viewed for every title, the premiere date for any Netflix show and movie, and whether a title was available globally. From the Hollywood Reporter: The list includes worldwide viewing for more than 18,000 movies and seasons of TV (18,214, to be exact) between January and June. Those 18,214 titles all had at least 50,000 hours of viewing over those six months, encompassing about 99 percent of all viewing on Netflix, vp strategy and analysis Lauren Smith told reporters during a presentation of the data on Tuesday. It is the deepest dive into viewing that Netflix (or any other streamer) has ever made public.

Among the highlights: The Night Agent was the biggest title on Netflix in the first half of 2023, racking up 812.1 million hours of viewing. Season two of Ginny & Georgia was second at 665.1 million hours, followed by Korean drama The Glory (622.8 million hours). Wednesday ranked fourth at 507.7 million hours of viewing, despite being released in November 2022. The company is using total hours viewed in this report as a way to measure engagement by its users rather than the “view” formula (total viewing hours divided by running time) it employs to compare titles in its weekly top 10 lists.

Original series and movies dominate the top of the chart, but Smith said the split between original and licensed titles was more even: About 55 percent of viewing was for originals and 45 percent was for licensed shows and films. Suits, which dominated the Nielsen U.S. streaming charts for much of the summer and fall, had a combined 599 million hours of viewing worldwide on Netflix across all nine seasons. The show’s first season ranked highest, coming in 67th place with 129.1 million hours. At the other end, a little more than 20 percent of the titles on Netflix’s list (3,813 in all) had very little viewing. The company rounded them to 100,000 hours but they would fall between 50,000 and 149,999 hours — barely a drop in the streamer’s more than 100 billion total hours of viewing for the six months.

What’s behind a supposed shortage of cybersecurity workers? Last month cybersecurity professional Ben Rothke questioned whether a “shortage” even existed. Instead Rothke argued that human resources “needs to understand how to effectively hire information security professionals. Expecting an HR generalist to find information security specialists is a fruitless endeavor at best.”

Rothke — a founding member of the Cloud Security Alliance — contacted Slashdot this week with “a follow-up piece” arguing there’s another problem. “How can you know how many security jobs there are if there’s no real statistical data available?” (Most articles on the topic cite the exact same two studies, which Rothke sees as “not statistically defendable.”)

Which begs the question — how many information security jobs are there? The short answer is that no one has a clue. The problem is that there is no statistically verifiable and empirically researched data on the number of current information security jobs and what the future holds. All data to date is based on surveys and extrapolations, which is a poor way to do meaningful statistical research… Based on LinkedIn job postings, veteran industry analyst Richard Stiennon found 15,849 job openings at 1,433 cybersecurity vendors. As to the millions of security jobs, he notes that the same could be extrapolated for office administrators. There are millions of companies, but it’s not like they all will need full-time security people.

Helen Patton is a veteran information security professional and CISO at Cisco Security Business Group, and the author of Navigating the Cybersecurity Career Path. As to the security jobs crisis, she notes that there are plenty of talented and capable people looking for jobs, and feels there’s in fact, no crisis at all. Instead, she says part of the issue is hiring managers who don’t truly stop to think about the skills required for a role, and how a candidate can demonstrate those skills. What they do is post jobs that ask for false proxies for experience — degrees, certifications, work experience — and as a consequence, they are looking for candidates that don’t exist. She suggests that fixing the hiring process will go a lot further to close the skills gap, than training a legion of new people.
Challenging this supposed glut of unfilled positions, Rothke also shares some recent stories from people who’ve recently looked for information security jobs. (“He tried to explain to the CIO that Agile was not an appropriate methodology for security projects unless they were primarily software-based. The CIO replied, ‘oh the CIO at Chase would tell you differently.’ Not realizing that most projects at the bank are software-based.”)

If you want to know how few information security jobs there really are — speak to people who have graduated from security bootcamps and master’s degree programs, and they will tell you the challenges they are facing… That’s not to say there are not lots of information security jobs. It’s just that there are not the exaggerated and hyperbolic amounts that are reported.

The free open-source text editor Notepad++ is celebrating its 20th anniversary, the blog OMG! Ubuntu reported this week, “with a new release filled with some neat new features.”

In Notepad++ 8.6 (the 238th release since 2003, for those keeping count) the Windows-based code tool [which can also be used on Linux] adds to its extensive feature set with an improved multi-edit feature.
A few 3rd-party Notepad++ plugins have offered similar functionality for a while, including BetterMultiSelection. And a bug report requesting to ability to “transform the column mode to multi-caret on HOME/END/Arrow keys” led to this native addition.
Their blog post includes an animated GIF of Notepad++ multi-edit in action.

“You can install Notepad++ on Ubuntu straight from the Ubuntu Software/App Center app (it’s a Snap Store). Alternatively, install the Windows build via WINE/CrossOver or, if you got the l33t skillz, build it by hand, from source.”

“Advent of Code” has begun. New programming puzzles will appear every day until Christmas at AdventOfCode.com — and the annual event (first started in 2015) has grown into a worldwide phenomenon. This year’s first puzzle has been completed by over 150,000 programmers (with another 115,652 completing Day Two’s puzzle). And 108,000 fans have also joined the Advent of Code subReddit.

Contest-related comments are popping up all around the web. Some participants are live streaming their puzzle-solving efforts on Twitch. Self-described computer nerd Gary Grady is tweeting cartoons about each day’s puzzle. JetBrains is even giving away some prizes in their “Advent of Code with Kotlin” event. And JetBrains developer advocate Sebastian Aigner is also hosting daily livestreams about each puzzle.

It’s hard to overstate how big this event has become. This year’s event attracted 60 sponsors, including Kotlin (for the third consecutive year), as well as Spotify, Shopify, and Sony Interactive Entertainment (as well as JPMorgan Chase, Bank of America, and American Express). Individual donors can get a special badge next to their name, and there’s also a shop selling coffee mugs and t-shirts. But at its core is real-world developer Eric Wastl (plus a team of loyal beta-testers) sharing his genuine fondness for computer programming. Wastl is also the creator of a satirical web page for the fast, lightweight, cross-platform framework Vanilla JS (“so popular that browsers have been automatically loading it for over a decade”) and also curates a collection of “things in PHP which make me sad”.

And you can find him on X sharing encouraging comments for this year’s participants.

Slashdot reader XXongo writes: Nuclear power plants have historically been built at gigawatt scale. Recently, however, there has been a new dawn seeing multiple projects to build Small Modular Reactors (“SMRs”), both funded by billionaires and by the U.S. Department of Energy.

Recently one of the players farthest ahead in the development, NuScale Power, canceled their headline project, but many other projects continue. In a lengthy analysis, Michael Barnard thinks that’s crazy, and attributes the drive toward small reactors to “a tangled web that includes Bill Gates, Silicon Valley, desperate coal towns, desperate nuclear towns, the inability of the USA to build big infrastructure, the U.S. Department of Energy’s budget, magical thinking and more.” Due to thermal inefficiencies, small reactors are more expensive per unit of power generated, he points out, and the SMR projects ignore most of the field’s history’s lessons about both the scale of reactors for commercial success and the conditions needed for success.

They are relying on Wright’s Law, that each doubling of the number of manufactured items in production manufacturing would bring cost per item down by 20% to 27%, but Barnard points out that the number of reactors needed to achieve enough economy of scale in production to make the reactors make economic sense is unrealistically optimistic. He concludes that only government programs can meet the conditions for successful deployment of nuclear power.

At one point Barnard characters SMRs as “a bunch of lab technologies that have been around for decades that depend on uranium from Russia, that don’t have the physical characteristics for cheap nuclear generation and don’t have the conditions for success for nuclear generation will be the saviours of the nuclear industry and a key wedge in fighting climate change…

“I like nuclear generation. I know it’s safe enough. I’m not concerned about radiation… I just know that it doesn’t have the conditions for success to be built and scaled economically in the 21st Century, and wind, water, solar, transmission and storage do.”

Gene Simmons is 74 years old. But as the singer for the classic rock band KISS left the stage after their final show, USA Today reports there was a surprise:
in the most on-brand KISS move even by KISS standards, before the quartet likely hit their dressing rooms after disappearing on stage in the blizzard of smoke and confetti that accompanied the set-closing “Rock and Roll All Nite,” a message blasted on the video screens: “A new KISS era starts now.”
Digital avatars of the band followed, playing their anthem, “God Gave Rock and Roll To You.”

ABC News reports:
The avatars were created by George Lucas’ special-effects company, Industrial Light & Magic, in partnership with Pophouse Entertainment Group, the latter of which was co-founded by ABBA’s Björn Ulvaeus. The two companies recently teamed up for the “ABBA Voyage” show in London, in which fans could attend a full concert by the Swedish band — as performed by their digital avatars. Per Sundin, CEO of Pophouse Entertainment, says this new technology allows Kiss to continue their legacy for “eternity.” He says the band wasn’t on stage during virtual performance because “that’s the key thing,” of the future-seeking technology. “Kiss could have a concert in three cities in the same night across three different continents. That’s what you could do with this.”

In order to create their digital avatars, who are depicted as a kind of superhero version of the band, Kiss performed in motion capture suits.

Experimentation with this kind of technology has become increasingly common in certain sections of the music industry. In October K-pop star Mark Tuan partnered with Soul Machines to create an autonomously automated “digital twin” called “Digital Mark.” In doing so, Tuan became the first celebrity to attach their likeness to OpenAI’s GPT integration, artificial intelligence technology that allows fans to engage in one-on-one conversations with Tuan’s avatar. Aespa, the K-pop girl group, frequently perform alongside their digital avatars — the quartet is meant to be viewed as an octet with digital twins. Another girl group, Eternity, is made up entirely of virtual characters — no humans necessary.

Kiss frontman Paul Stanley told ABC News that “The band deserves to live on because the band is bigger than we are.”

Today is the 20th anniversary of its last flight of the supersonic Concorde aircraft. It was faster than the speed of sound, travelling at speeds of 1,350 mph (2,170 km/h).

Long-time Slashdot reader schwit1 shared an article from the Telegraph:
As the space race raged and dominated headlines, the U.S. and the Soviet Union were equally competitive about being the first post-war superpower to create a commercial jetliner that could travel faster than the speed of sound.” Both started work on secret projects, at the same time that Britain and France — who were less hell-bent on imprinting their superiority on geopolitics, but blessed with many of the world’s finest engineering minds — were in pursuit of the same goal.

It has been known for decades that the three-horse race wasn’t run entirely fairly. While the Americans, with their colossal and largely pointless Boeing 2707, never got close to getting airborne (they scrapped the project in 1971), the Soviet-built Tupolev Tu-144 won the race in 1968. When it did, though, its design similarities to Concorde appeared to confirm suspicions that the blueprints might have been leaked by espionage. In the late 1990s, it was revealed that an aeronautical engineer codenamed Agent Ace was one such spy. Recruited in 1967, he allegedly handed over some 90,000 pages of detailed technical specifications on new aircraft — including Concorde, the Super VC-10 and Lockheed L-1011 — to the KGB, the foreign intelligence and domestic security agency of the Soviet Union.
The identity of Agent Ace is revealed in Concorde: The Race for Supersonic, a new two-part documentary by the UK public broadcasting station Channel 4.

The Telegraph adds:
With the rich benefit of hindsight, John Britton isn’t entirely surprised there was a Soviet mole in the factory. It was a long time ago, 1965, but something — or someone — at Filton Aerodrome seemed fishy. “We had dozens, maybe hundreds of people working on the project, and we didn’t have enough permanent staff so we took on contractors, all sorts of characters,” Britton says. At the time he was a 19-year-old apprentice engineer, working for British Aeroplane Company (BAC) in the design office for a supersonic, passenger-carrying aircraft. An aircraft that would, ideally, fly before the Soviet Union’s competing effort did.
“There was one chap working there… He used to stay behind, he’d do a lot of overtime in the drawing library, taking prints off the microfilms of designs…” Britton, who is now 76, initially assumed the man — he thinks his name was George — was merely conscientious and needed copies for his work. He can titter at the memory now. “It was only afterwards, when the Soviet aircraft came out and it looked remarkably like Concorde, when we thought… ‘Ah’.”

For circuit-based quantum computations, the achievable circuit complexity is limited by the quality of timekeeping. That’s according to a new analysis published in the journal Physical Review Letters exploring “the effect of imperfect timekeeping on controlled quantum dynamics.”

An announcement from the Vienna University of Technology explains its significance. “The research team was able to show that since no clock has an infinite amount of energy available (or generates an infinite amount of entropy), it can never have perfect resolution and perfect precision at the same time. This sets fundamental limits to the possibilities of quantum computers.”

ScienceAlert writes:
While the issue isn’t exactly pressing, our ability to grow systems based on quantum operations from backroom prototypes into practical number-crunching behemoths will depend on how well we can reliably dissect the days into ever finer portions. This is a feat the researchers say will become increasingly more challenging…

“Time measurement always has to do with entropy,” says senior author Marcus Huber, a systems engineer who leads a research group in the intersection of Quantum Information and Quantum Thermodynamics at the Vienna University of Technology. In their recently published theorem, Huber and his team lay out the logic that connects entropy as a thermodynamic phenomenon with resolution, demonstrating that unless you’ve got infinite energy at your fingertips, your fast-ticking clock will eventually run into precision problems. Or as the study’s first author, theoretical physicist Florian Meier puts it, “That means: Either the clock works quickly or it works precisely — both are not possible at the same time….”

[F]or technologies like quantum computing, which rely on the temperamental nature of particles hovering on the edge of existence, timing is everything. This isn’t a big problem when the number of particles is small. As they increase in number, the risk any one of them could be knocked out of their quantum critical state rises, leaving less and less time to carry out the necessary computations… This appears to be the first time researchers have looked at the physics of timekeeping itself as a potential obstacle. “Currently, the accuracy of quantum computers is still limited by other factors, for example the precision of the components used or electromagnetic fields,” says Huber. “But our calculations also show that today we are not far from the regime in which the fundamental limits of time measurement play the decisive role.”

But is it all also just a big waste of time? The article notes there’s now even CAPTCHA-solving services you can hire. (“2Captcha will solve a thousand CAPTCHAs for a dollar, using human workers paid as low as 50 cents an hour. Newer companies, such as Capsolver, claim to instead be using AI and charge roughly the same price.”)

And they also write that this summer saw more discouraging news:

In a recent study from researchers at UC Irvine and Microsoft:
– most of the 1,400 human participants took 15 to 26 seconds to solve a CAPTCHA with a grid of images, with 81% accuracy.

– A bot tested in March 2020, meanwhile, was shown to solve similar puzzles in an average of 19.9 seconds, with 83% accuracy.

The article ultimately argues that for roughly 20 years, “CAPTCHAs have been engaged in an arms race against the machines,” and that now “The burden is on CAPTCHAs to keep up” — which they’re doing by evolving.

The most popular type, Google’s reCAPTCHA v3, should mostly be okay. It typically ascertains your humanity by monitoring your activity on websites before you even click the checkbox, comparing it with models of “organic human interaction,” Jess Leroy, a senior director of product management at Google Cloud, the division that includes reCAPTCHA, told me.

But the automotive site Motor Biscuit speculates something else could also be happening. “Have you noticed it likes to ask about cars, buses, crosswalks, and other vehicle-related images lately?”
Google has not confirmed that it uses the reCAPTCHA system for autonomous vehicles, but here are a few reasons why I think that could be the case. Self-driving cars from Waymo and other brands are improving every day, but the process requires a lot of critical technology and data to improve continuously.

According to an old Google Security Blog, using reCAPTCHA and Street View to make locations on Maps more accurate was happening way back in 2014… [I]t would ask users to find the street numbers found on Google Street View and confirm the numbers matched. Previously, it would use distorted text or letters. Using this data, Google could correlate the numbers with addresses and help pinpoint the location on Google Maps…

Medium reports that more than 60 million CAPTCHAs are being solved every day, which saves around 160,000 human hours of work. If these were helping locate addresses, why not also help identify other objects? Help differentiate a bus from a car and even choose a crosswalk over a light pole.

An anonymous reader writes: Using realistic ecological modeling, scientists led by Western Sydney University’s Jürgen Knauer found that the globe’s vegetation could actually be taking on about 20% more of the CO2 humans have pumped into the atmosphere and will continue to do so through to the end of the century.

“What we found is that a well-established climate model that is used to feed into global climate assessments by the likes of the IPCC (Intergovernmental Panel on Climate Change) predicts stronger and sustained carbon uptake until the end of the 21st century when extended to account for the impact of some critical physiological processes that govern how plants conduct photosynthesis,” said Knauer.

Mathematical models of ecological systems are used to understand complex ecological processes and in turn attempt to predict how the real ecosystems they’re based on will change. The researchers found that the more complex their modeling, the more surprising the results – in the environment’s favor.

Current models, the team adds, are not that complex so likely underestimate future CO2 uptake by vegetation… [T]he modeling makes a strong case for the value of greening projects and their importance in comprehensive approaches to tackling global warming.
