Mark Zuckerberg's virtual reality business is to introduce a mandatory distance between people's digital avatars after warnings that the social media tycoon's plans for a metaverse will lead to a new wave of online harassment. From a report: Zuckerberg, the founder of Facebook, is making a multibillion-dollar bet on VR as the next source of growth for his empire but his strategy has already been dogged by warnings that virtual worlds are rife with abuse. In December a user testing Horizon Worlds, a VR app owned by Zuckerberg's Meta business, complained of being groped online and called for a protective bubble around their avatar, or digital representation of themselves. "Sexual harassment is no joke on the regular internet but being in VR adds another layer that makes the event more intense," said the user.

U.S. lawmakers are introducing "Right to Repair" legislation this week to ensure consumers can get vehicles, electronic devices and agriculture equipment serviced by independent outlets. Reuters reports: Representative Bobby Rush, a Democrat, said Thursday he had introduced legislation to ensure vehicle owners and independent repair shops have equal access to repair and maintenance tools as automakers' dealerships. Representatives Mondaire Jones, a Democrat, and Republican Victoria Spartz introduced separate legislation Wednesday dubbed the Freedom to Repair Act to reform copyright law to make it easier for consumers to get repairs. Public Knowledge Policy Counsel Kathleen Burke said the bill would allow "consumers to repair their own devices without needing to get the Copyright Office's permission every three years."

Rush's bill would require all tools and equipment, wireless transmission of repair and diagnostic data and access to on-board diagnostic systems needed for repairs be made available to the independent repair industry. Rush said it would "end manufacturers' monopoly on vehicle repair and maintenance and allow Americans the freedom to choose where to repair their vehicles." Rush's bill would create a committee to provide recommendations to the FTC on addressing barriers to vehicle repairs. Yesterday, Sen. Jon Tester (D-Mont.) introduced a bill to allow farmers to fix their own equipment. Specifically, the bill "would require agriculture equipment manufacturers to make spare parts, instruction manuals and software codes publicly available, allowing farmers to fix devices by themselves or hire third-party mechanics of their own choosing," reports NBC News.

Long-time Slashdot reader Hope Thelps brings news about the future of self-driving cars. "The law commisions of England and Wales and of Scotland (statutory bodies which keep the laws in those countries under review) are recommending a shift in accident liability away from 'drivers' when autonomous cars become a reality."

The BBC reports: Human drivers should not be legally accountable for road safety in the era of autonomous cars, a report says. In these cars, the driver should be redefined as a "user-in-charge", with very different legal responsibilities, according to the law commissions for England and Wales, and Scotland. If anything goes wrong, the company behind the driving system would be responsible, rather than the driver....

In the interim, carmakers must be extremely clear about the difference between self-drive and driver-assist features. There should be no sliding scale of driverless capabilities — a car is either autonomous or not....

Transport Minister Trudy Harrison said the government would "fully consider" the recommendations. The Scottish and Welsh governments will also decide whether to introduce legislation.
The BBC also summarized some of the reports other recommendations:

• Data to understand fault and liability following a collision must be accessible
• Sanctions for carmakers who fail to reveal how their systems work

Manufacturers and other buyers of computer chips had less than five days' supply of some chips on hand late last year, leaving them vulnerable to any disruptions in deliveries, the Commerce Department reported Tuesday as it pushed Congress to endorse federal aid for chip makers. The Washington Post reports: Manufacturers' median chip inventory levels have plummeted from about 40 days' supply in 2019 to less than five days, according to a survey of 150 companies worldwide that the Commerce Department conducted in September. "This means a disruption overseas, which might shut down a semiconductor plant for 2-3 weeks, has the potential to disable a manufacturing facility and furlough workers in the United States if that facility only has 3-5 days of inventory," the Commerce Department concluded in a six-page summary of its findings.

The lack of chip inventory leaves auto manufacturers and other chip users with "no room for error," Commerce Secretary Gina Raimondo said Tuesday as she presented the findings. "A covid outbreak, a storm, a natural disaster, political instability, problem with equipment -- really anything that disrupts a [chip-making] facility anywhere in the world, we will feel the ramifications here in the United States of America," she said. "A covid outbreak in Malaysia has the potential to shut down a manufacturing facility in America."

"The reality is Congress must act," Raimondo added, urging lawmakers to pass a proposal for $52 billion in federal subsidies to incentivize construction of chip factories. "Every day we wait, we fall further behind." The Senate passed the measure last year. The legislation has been tied up for months in the House, though House Democrats are expected to introduce their version of the legislation as soon as this week. Industry executives say federal funding is likely to create more long-term supply of chips but not to alleviate the short-term shortages because chip factories take years to build.

The Federal Communications Commission is the next US regulator hoping to hold companies more accountable for data breaches. From a report: Chairwoman Jessica Rosenworcel has shared a rulemaking proposal that would introduce stricter requirements for data breach reporting. Most notably, the new rules would require notifications for customers affected by "inadvertent" breaches -- companies that leave data exposed would have to be just as communicative as victims of cyberattacks. The requirements would also scrap a mandatory one-week waiting period for notifying customers. Carriers, meanwhile, would have to disclose reportable breaches to the FCC in addition to the FBI and Secret Service. Rosenworcel argued the tougher rules were necessary to account for the "evolving nature" of breaches and the risks they posed to victims. People ought to be protected against larger and more frequent incidents, the FCC chair said -- that is, regulations need to catch up with reality.

"Until recently," writes the NY Times' Jay Caspian Kang, "my daughter and I were somehow able to avoid the king of toy videos: Ryan Kaji." There's no one way to describe what Kaji, who is now 10 years old, has done across his multiple YouTube channels, cable television shows and live appearances: In one video, he is giving you a tour of the Legoland Hotel; in another, he splashes around in his pool to introduce a science video about tsunamis. But for years, what he has mostly done is play with toys: Thomas the Tank Engine, "Paw Patrol" figures, McDonald's play kitchens. A new toy and a new video for almost every day of the week, adding up to an avalanche of content that can overwhelm your child's brain, click after click. Kaji has been playing with toys on camera since Barack Obama was in the White House.

Here are a few of the companies that are now paying him handsomely for his services: Amazon, Walmart, Nickelodeon, Skechers. Ryan also has 10 separate YouTube channels, which together make up "Ryan's World" [31.2M subscribers], a content behemoth whose branded merchandise took in more than $250 million last year. Even conservative estimates suggest that the Kaji family take exceeds $25 million annually.
Thanks to long-time Slashdot reader theodp for sharing the article — and for summarizing one of its most startling details. "Not too surprisingly, Ryan's mother and father paused their teaching and engineering careers to focus on Ryan's empire after seeing the reaction to Ryan's breakout 2016 video, which now has 2+ billion YouTube views."

The Times' reporter quips that the videos capture glimpses from "the only world in which children do not stare at screens" — then wonders if that's even true, sharing their observation from the filming of a special toy-themed TV show with Ryan.

"I overheard a crew member say to him, 'If you finish this scene, you can play Minecraft.' "

The programming language of the year has been announced by the TIOBE Index: Python!

But noting that the TIOBE index is based on the number of search results for a programming language across popular search engines, a headline at The Next Web asks: "What does this title even mean?" [TIOBE] takes services such as Google, QQ, Sohu, Amazon, and Wikipedia to calculate the results. TIOBE uses "+" programming" query and a special formula to devise these ratings that change every month. You can read more about the whole process here. The programming language of the year title is decided by the jump in ratings year-on-year. Python overtook C# by a margin of 0.13% — almost a photo finish.

The index doesn't indicate the best or most efficient programming language, nor does it measure the amount of code written in a language across the internet. It simply gives us a high-level understanding of resources and pages available on the web related to them.

There's a huge amount of criticism towards the TIOBE index, especially as it uses one query and doesn't consider non-English languages. The organization said that it's trying to introduce more parameters to calculate the ratings.
TIOBE's annual award is being called "prestigious" — by the announcement at TIOBE.com: The award is given to the programming language that has gained the highest increase in ratings in one year. C# was on its way to get the title for the first time in history, but Python surpassed C# in the last month.

Python started at position #3 of the TIOBE index at the beginning of 2021 and left both Java and C behind to become the number one of the TIOBE index. But Python's popularity didn't stop there. It is currently more than 1 percent ahead of the rest [with a "rating" of 13.58%]. Java's all time record of 26.49% ratings in 2001 is still far away, but Python has it all to become the de facto standard programming language for many domains. There are no signs that Python's triumphal march will stop soon.
In fact, this makes the second year in a row Python has won TIOBE's annual award.

But it's as good a conversation-starter as any. ZDNet reminds us that Microsoft hired Python creator Guido van Rossum in 2020 to work on improving Python's efficiency, while the second most popular language on TIOBE's annual list, C#, "is a language designed by Microsoft technical fellow Anders Hejlsberg for the .NET Framework and Microsoft's developer editing tool Visual Studio."

And ZDNet also spottted a few other patterns in TIOBE's year-end look at programming language popularity: There were several movers and shakers this year. Rust, a systems programming language that deals with memory safety flaws, is now in 26th position, ahead of MIT's Julia, and Kotlin, a language endorsed by Google for Android app development. Rust was a stand out language in 2021, gaining backing from Facebook, Amazon Web Services, Microsoft Azure and Google Cloud.

Apple's Swift for iOS and macOS app development jumped from 13th to 10th place, while Google's Go inched up from 14 to 13, according to Tiobe. Kotlin moved from 40th to 29th. Google's Dart dropped from 25th to 37th position, Julia fell from 23rd to 28th position, while Microsoft TypeScript dropped from from 42 to 49.

The top 10 languages in Tiobe's list for January 2022 were Python, C, Java, C++,C#, Visual Basic, JavaScript, Assembly Language, SQL, and Swift.

Kosovo's government on Tuesday introduced a ban on cryptocurrency mining in an attempt to curb electricity consumption as the country faces the worst energy crisis in a decade due to production outages. Reuters reports: "All law enforcement agencies will stop the production of this activity in cooperation with other relevant institutions that will identify the locations where there is cryptocurrency production," Economy and Energy Minister Artane Rizvanolli said in a statement. Faced with coal-fired power plant outages and high import prices authorities were forced last month to introduce power cuts.

European gas prices soared more than 30% on Tuesday after low supplies from Russia reignited concerns about an energy crunch as colder weather approaches. In December, Kosovo declared a state of emergency for 60 days which will allow the government to allocate more money to energy imports, introduce more power cuts and harsher measures. The country of 1.8 million people is now importing more than 40% of its consumed energy with high demand during the winter when people use electricity mainly for heating. Around 90% percent of energy production in Kosovo is from lignite, a soft coal that produces toxic pollution when burnt.

Instant-delivery startups promising to ferry groceries to customers in 15 minutes or less have rushed to expand in major cities like New York and Chicago in the past year. But they're burning far more cash in the U.S. than in other countries where they operate, causing several of them to test major changes to their business model -- including longer delivery windows that could allow the startups to pack in more orders per trip. The Information: One example is Jokr, last valued at $1.2 billion on paper, which told investors in the fall it would experiment with slower delivery times and a subscription service to reduce its heavy losses, according to a person with direct knowledge of the matter. In the month of August, the one-year-old startup was losing $159 per order in the U.S., according to internal data sent to investors in the fall, viewed by The Information. Buyk, a smaller instant-delivery startup, may also introduce longer delivery windows, its CEO said in an interview. And Fridge No More, an instant-delivery firm founded in 2020, plans to introduce a new private-label offering for items like olive oil and milk and to sell prepared foods such as pizza to similarly boost margins, according to a fundraising document seen by The Information. The pressure to change strategy so soon after launching illustrates the challenge of operating an instant-delivery business in the U.S., where intense competition from other rapid-commerce startups and more-established delivery firms like Instacart make it more expensive to attract customers. Labor and real estate costs are also much higher in the U.S than in developing markets like Brazil or Turkey, where some startups first set up their rapid-delivery operations.

An anonymous reader quotes a report from BleepingComputer: The Kyoto University in Japan has lost about 77TB of research data due to an error in the backup system of its Hewlett-Packard supercomputer. The incident occurred between December 14 and 16, 2021, and resulted in 34 million files from 14 research groups being wiped from the system and the backup file. After investigating to determine the impact of the loss, the university concluded that the work of four of the affected groups could no longer be restored. All affected users have been individually notified of the incident via email, but no details were published on the type of work that was lost.

At the moment, the backup process has been stopped. To prevent data loss from happening again, the university has scraped the backup system and plans to apply improvements and re-introduce it in January 2022. The plan is to also keep incremental backups -- which cover files that have been changed since the last backup happened -- in addition to full backup mirrors. While the details of the type of data that was lost weren't revealed to the public, supercomputer research costs several hundreds of USD per hour, so this incident must have caused distress to the affected groups. The Kyoto University is considered one of Japan's most important research institutions and enjoys the second-largest scientific research investments from national grants. Its research excellence and importance is particularly distinctive in the area of chemistry, where it ranks fourth in the world, while it also contributes to biology, pharmacology, immunology, material science, and physics.

An anonymous reader shares a report: The HDMI standards are a mess. HDMI 2.1, in particular, is a uniquely frustrating mess, with haphazard support among TV manufacturers, cable makers, and devices that make setting up, say 120Hz gaming on a PS5 or Xbox Series X a uniquely harrowing experience. Fortunately, the HDMI Forum is swooping in ahead of CES with its latest revision to the HDMI specification stack, HDMI 2.1a, which is here to make everything better and simpler... I'm kidding, of course. It's gonna make things more complicated. It's a new HDMI standard, what on earth did you expect?

Let's start with the good: HDMI 2.1a is an upcoming revision to the HDMI 2.1 stack and adds a major new feature, Source-Based Tone Mapping, or SBTM. SBTM is a new HDR feature that offloads some of the HDR tone mapping to the content source (like your computer or set-top box) alongside the tone mapping that your TV or monitor is doing. SBTM isn't a new HDR standard -- it's not here to replace HDR10 or Dolby Vision. Instead, it's intended to help existing HDR setups work better by letting the content source better optimize the content it passes to the display or by removing the need to have the user manually calibrate their screens for HDR by having the source device configure content for the specific display. Other use cases could be for when there's a mix of content types, like for streamers (who could have an HDR game playing alongside a window of black and white text), displaying each area of content.

Phoronix reports: The Linux 5.17 kernel when it kicks off next month is slated to introduce a new driver "x86-android-tablets" just for dealing with all the quirky/buggy x86 tablets out there.

Longtime Linux developer Hans de Goede of Red Hat has been responsible for numerous x86 laptop/tablet improvements in recent years along with other desktop-related improvements at Red Hat. He has now queued up into the x86 platform drivers tree the x86-android-tablets driver he wrote for dealing with the mess of x86 (mostly Android) tablets that don't behave properly out-of-the-box with Linux.

As part of the ACPI DSDT (Differentiated System Description Table), many x86 tablets have simply invalid entries and other problems that cause issue when trying to run mainline Linux on said hardware. Hans explains as part of the commit currently in the platform-drivers-x86 "for-next" branch....

"This driver, which loads only on affected models based on DMI matching, adds DMI based instantiating of kernel devices for devices which are missing from the DSDT, fixing e.g. battery monitoring, touchpads and/or accelerometers not working."

This new x86-android-tablets driver will basically be a catch-all solution for overrides based on device matching. Hans ended the patch message with, "This is the least ugly option to get these devices to fully work and to do so without adding any extra code to the main kernel image (vmlinuz) when built as a module."

A Forbes associate editor covering privacy, cybercrime, and security/surveillance reports on a recently-revealed search warrant.

Instead of investigating a photo, it asked Google to provide information on a suspect who allegedly owned graphic illegal cartoons involving children: That kind of content is potentially illegal to own under U.S. law and can be detected by Google's anti-child sexual material (CSAM) systems, a fact not previously discussed in the public domain, the warrant reveals.... Google also uses machine learning tools to look at files and analyze them for any sign they're of abused children....

As per its legal requirements, Google handed information on what it found, as well as the IP addresses used to access the images, to the National Center for Missing and Exploited Children (NCMEC), which then passed on the findings to the DHS Homeland Security Investigations unit. Investigators used the IP addresses provided by Google to identify the suspect as the alleged owner of the cartoons, and searched his Google account, receiving back information on emails to and from the defendant. It appears the suspect may actually be a known artist. As no charges have been filed, Forbes isn't publishing his name, but the man identified in the warrant had won several small Midwest art competitions, and one artwork from the 1990s had been mentioned in a major West Coast newspaper...

Google, meanwhile, has in recent years released transparency reports showing how many times it reports issues to NCMEC. The figures reveal a disturbing trend. In the first six months of 2021, it found more than 3.4 million pieces of potentially illegal content in 410,000 separate reports. That was up from 2.9 million in 365,000 reports in the last six months of 2020, and well over double that from January to June 2020, when 1.5 million pieces of CSAM material were discovered and reported to NCMEC in 180,000 reports...

As Google doesn't end-to-end encrypt its communications tools like Gmail or its file storage tech like Drive, it's still possible for the tech company to scan for illegal content. And as it has no plans to introduce those features, law enforcement can still rely on Google to warn NCMEC when abuse happens on its servers. Whether the majority of users will want Google to scan people's accounts so it can help find child abusers, or have improved privacy with end-to-end encryption instead, the Mountain View, California-based business will have to struggle with that balance in perpetuity. The same goes for any one of its rivals.

InfiniteZero writes: Imaginary numbers are necessary to accurately describe reality, two new studies have suggested. Imaginary numbers are what you get when you take the square root of a negative number, and they have long been used in the most important equations of quantum mechanics, the branch of physics that describes the world of the very small. When you add imaginary numbers and real numbers, the two form complex numbers, which enable physicists to write out quantum equations in simple terms. But whether quantum theory needs these mathematical chimeras or just uses them as convenient shortcuts has long been controversial. In fact, even the founders of quantum mechanics themselves thought that the implications of having complex numbers in their equations was disquieting. In a letter to his friend Hendrik Lorentz, physicist Erwin Schrodinger -- the first person to introduce complex numbers into quantum theory, with his quantum wave function -- wrote, "What is unpleasant here, and indeed directly to be objected to, is the use of complex numbers. quantum wave function is surely fundamentally a real function."

Schrodinger did find ways to express his equation with only real numbers alongside an additional set of rules for how to use the equation, and later physicists have done the same with other parts of quantum theory. But in the absence of hard experimental evidence to rule upon the predictions of these "all real" equations, a question has lingered: Are imaginary numbers an optional simplification, or does trying to work without them rob quantum theory of its ability to describe reality? Now, two studies, published Dec. 15 in the journals Nature and Physical Review Letters, have proved Schrodinger wrong. By a relatively simple experiment, they show that if quantum mechanics is correct, imaginary numbers are a necessary part of the mathematics of our universe. "The early founders of quantum mechanics could not find any way to interpret the complex numbers appearing in the theory," lead author Marc-Olivier Renou, a theoretical physicist at the Institute of Photonic Sciences in Spain, told Live Science in an email. "Having them [complex numbers] worked very well, but there is no clear way to identify the complex numbers with an element of reality." To test whether complex numbers were truly vital, the authors of the first study devised a twist on a classic quantum experiment known as the Bell test. The test was first proposed by physicist John Bell in 1964 as a way to prove that quantum entanglement -- the weird connection between two far-apart particles that Albert Einstein objected to as "spooky action at a distance" -- was required by quantum theory.

Before Google Wifi was announced alongside the original Pixel phone, Google a year earlier released OnHub-branded routers from Asus and TP-Link. In late 2022, Google will end support for OnHub routers that will be seven years old at that time. 9to5Google reports: At six years old, currently, Google said "a lot has changed" in the router landscape, and that it will end support for them on December 19, 2022. This is according to emails that customers (via Droid-Life) have been receiving and a new support document. Until that date, "your OnHub router will continue to work as normal," but without security updates for new software features. The last combined OnHub and Google Wifi update came in October of 2019, while Google and Nest Wifi have had several OTAs since then. That said, a year later, the Google Home app added support for managing OnHub hardware ahead of the Google Wifi companion client getting deprecated.

Google recommends you "upgrade to a new Wi-Fi setup today" and emailed a 40% off Nest Wifi offer to existing OnHub router users that will be available until March 31, 2022. After December 19 next year, the OnHub router will continue to "provide a Wi-Fi signal" but no longer be manageable through the Google Home app, which is the downside of routers that are entirely managed via the cloud/companion app and do not offer local controls. While OnHub routers will continue to work and not disrupt existing networks, Google's decision to remove the ability to change basic settings is quite aggressive. Hopefully, the 2016 Google Wifi will see a longer support period.

An underwater hockey league connected the founders of the Solana blockchain to investors who bought the Solana token. The 4,300-fold increase in the price of the blockchain's tokens explains why more VC funds want to hold these assets. The Information: When Solana Labs CEO Anatoly Yakovenko tried to raise money in 2018 to develop his idea for a faster blockchain for financial transactions, bitcoin prices were diving and investors were leery of blockchain startups. Then the former Qualcomm engineer convinced a friend he met playing underwater hockey to become an early investor. And that swim buddy went on to introduce Yakovenko, 41, to two other backers. Later that year, the five co-founders of Solana Labs sold 79.25 million tokens for pennies each to help the startup develop the Solana blockchain. Some of the early token buyers, including Multicoin Capital, 500 Startups and a founder of Race Capital, have reaped huge gains from these first sales, in some cases generating $1 billion in returns. The spike in tokens like Solana, which are worth about 4,300 times their initial sales price, explain why traditional venture capital firms such as Andreessen Horowitz and Sequoia Capital are shaking up their legal structures to hold more digital assets. This is how Solana's first backers got in on one of the biggests scores in crypto investments.

The Solana token, which confers ownership rights to the Solana blockchain, is now the world's fifth most valuable, with a market capitalization of about $50 billion, according to CoinMarketCap. Altogether, Solana Labs has sold 307 million SOL tokens, which have helped power the 78-employee startup's growth and the blockchain's development in lieu of equity financing. Solana token prices have jumped as the blockchain proved it can handle transactions faster than standard financial institutions. It also outperforms Ethereum, an older blockchain technology underpinning decentralized finance, or DeFi, a peer-to-peer system where financial transactions are completed without an intermediary. The Solana blockchain can already complete 65,000 transactions per second compared to 1,700 for credit card processor Visa and just 15 for Ethereum. An Ethereum upgrade expected for next year aims to bump that rate to 100,000 transactions, but that transition has been delayed for almost two years.

"Windows Me was unstable, unloved and unusable," remembered Computerworld last year, on the 20th anniversary of its release, calling it "a stink bomb of an operating system." Windows Me was a ghastly, slapdash piece of work, incompatible with lots of hardware and software. It frequently failed during the installation process — which should have been the first sign for people that this was an operating system they shouldn't try.Often, when you tried to shut it down, it declined to do so, like a two-year-old throwing a temper tantrum over being forced to go to sleep. It was slow and insecure. Its web browser, Internet Explorer, frequently refused to load web pages.
But they ultimately argue that it wasn't as bad as Windows Vista, which "simply refused to run, or ran so badly it was useless on countless PCs. Not just old PCs, but even newly bought PCs, right out of the box, with Vista installed." And they conclude that the worst Microsoft OS of all is still Windows 8. ("You want bad? You want stupid? You want an operating system that not only was roundly reviled by consumers and businesses alike, but also set Microsoft's business plans back years?")

Slashdot reader alaskana98 even remembers Windows ME semi-fondly as "the last Microsoft OS to use the Windows 95 codebase." While rightly being panned as a buggy and crash-prone OS — indeed it was labelled as the worst version of Windows ever released by Computer World — it did introduce a number of features that continue on to this very day. Those features include:

-A personalized start menu that would show your most recently accessed programs, today a common feature in the Windows landscape.
-Software support for DVD playback. Previously one needed a dedicated card to playback DVDs.
-Windows Movie Maker and Windows Media Player 7, allowing home users to create, edit and burn their own digital home movies. While seemingly pedestrian in today's times, these were groundbreaking features for home users in the year 2000.
-The first iteration of System Restore — imagine a modern version of Windows not having the ability to conveniently restore to a working configuration — before Windows ME, this was simply not a possibility for the average home user unless you had a rigorous backup routine.
-The removal of real-mode DOS. While very controversial at the time, this change arguably improved the speed and reliability of the boot process.

Love it or hate it (well, lets face it, if you were a computer user at that point you probably hated it) — Windows ME did make several important contributions to the modern OS landscape that are often overlooked to this day. Do you have any stories from the heady days of late 2000 when Windows ME was first released?
Slashdot reader Z00L00K remembers in a comment that "The removal of real-mode DOS is what REALLY made ME impossible to use for most of us at the time. It broke backwards compatibility so hard that the only way out was to use any of the earlier versions of Windows instead!"

Is this re-awakening images of the year 2000 for anyone? Share your own memories and thoughts in the comments.

What do you remember about Windows ME?

Astronomers say they've located six galaxies that appear to have either very little or absolutely no dark matter. The team will present its findings in Monthly Notices of the Royal Astronomical Society. CNET reports: Mentioning that they'd previously been told "measure again, you'll see there will be dark matter around your galaxy," the researchers zeroed in on one seemingly dark-matter-free region dubbed AGC 114905 to strengthen their evidence. Lurking 250 million light-years away from Earth, it's about the size of the Milky Way, with a thousand times fewer stars. So it's rather dim. The researchers used a standard technique to detect the presence of dark matter in AGC 114905 that involves graphing the position and rotation speed of the galaxy's gas. After 40 hours of scrutiny with the high-powered Very Large Array Radio Telescope in New Mexico, they found the movements of the gas were perfectly explainable by normal matter alone.

"The problem remains that the theory predicts that there must be dark matter in AGC 114905," Pavel Mancera Piñabut of the Kapteyn Astronomical Institute at the University of Groningenour and an author of the study, said in a statement, referring to classic dark matter hypotheses. "Observations say there isn't -- in fact, the difference between theory and observation is only getting bigger." One caveat, the team says, is that perhaps the angle at which they viewed AGC 114905 affected their observational results. "But that angle has to deviate very much from our estimate before there is room for dark matter again," Tom Oosterloo of Astron at the Netherlands Institute for Radio Astronomy and co-author of the study, said in a statement.

And if they're correct? The team offers up a few reasons for why AGC 114905 may not have any dark matter. For instance, what if super large galaxies nearby somehow stripped it of the force? As a rebuttal, though, Mancera Pinabut says there don't seem to be any such galaxies in the vicinity. Further, he says, "in the most reputed galaxy formation framework, the so-called cold dark matter model, we would have to introduce extreme parameter values that are far beyond the usual range. Also with modified Newtonian dynamics, an alternative theory to cold dark matter, we cannot reproduce the motions of the gas within the galaxy."

An anonymous reader quotes a report from BleepingComputer: Eurostar is testing a new biometric facial recognition technology on passengers traveling from London's St Pancras International station to continental Europe. The passengers will be given the opportunity to complete their pre-departure ticket and passport checks via the new biometric system, called the "SmartCheck" lane. Those who take this option will be allowed to board the train without going through the typically tedious ID verification procedures. The system will involve two facial scans, one at the ticket gate to verify the ticket check and one at the UK Exit Checkpoint, to confirm that the passport information is valid.

The goal, according to Eurostar, is to eliminate queues and expedite the boarding process, not only improving customer satisfaction but also minimizing the chances for viral transmission. The system will be trialed with a limited number of invited passengers and won't involve the UK's or Schengen entry controls. Eurostar announced its intention to introduce a facial recognition system to replace physical tickets and passport checks last year, and facial recognition company iProov helped them build it. iProov is a proponent of what they call "passive authentication", which is facial recognition without the user having to do anything. The user consents to the platform by visiting an online portal to register with their information and takes an image of their face with the smartphone or webcam. When they reach a physical checkpoint, they simply look at the camera, and the system authenticates them effortlessly.

Bitcoin's long-awaited Taproot update will occur in the coming days, with most sources suggesting Saturday as its activation date. Crypto Briefing reports: Taproot is an upgrade that will improve Bitcoin's capacity for scripting, bringing it in line with competing blockchains like Ethereum that already have programmable smart contracts. Taproot will also introduce MAST (Merkelized Abstract Syntax Tree), which will make it more difficult to trace and analyze Bitcoin transactions. It does so by making complex transactions -- such as multi-signature transactions and Lightning Network transactions -- indistinguishable from basic transactions. The upgrade will also include Schnorr signatures, which will create smaller transaction sizes through data aggregation.

Together, these features mean that developers will be able to create more extensive Bitcoin applications, while end-users will be able to benefit from cheaper, more private transactions. Taproot is Bitcoin's most significant upgrade since 2017, when the cryptocurrency introduced a controversial new feature called SegWit. The Taproot upgrade is much less likely to cause division.

Though Taproot already gained support from miners earlier this week, 800 blocks will need to be mined under those conditions before the feature is actually activated. NiceHash's countdown suggests that the upgrade will occur at 1:00 UTC on Saturday, Nov. 14. Another countdown website, Taproot.watch concurs with that estimate, suggesting that there are just 339 blocks left to mine at the time of writing.
