An anonymous reader quotes a report from Ars Technica: Apple hasn't stopped selling Intel Macs just yet, but it's safe to say that we'll never see a Mac with one of Intel's 12th-generation Core processors in it. But that minor detail isn't stopping the Hackintosh community from supporting new Intel and AMD processors and platforms. The developers behind OpenCore, the most powerful and actively maintained bootloader for loading macOS on standard PC hardware, improved its Alder Lake support in this month's release, version 0.7.7. In a blog post over the weekend, the developers also detailed their efforts to update OpenCore and its associated software to work with Intel's Z690 chipset.

The key to building a functional Hackintosh is normally to build a PC that's as close as possible to actual Intel Mac hardware -- most crucially, the CPU, GPU, and chipset. OpenCore's job is to bridge whatever gap is left between your PC and real Mac hardware so that macOS boots and works properly. It adds support for reading and booting macOS filesystems, loads kernel extensions to support additional hardware, tells macOS how to handle your system's audio outputs and USB ports, and spoofs hardware to take advantage of macOS's built-in support (if, for example, your PC has a GPU that is similar to but not quite identical to a GPU included in a real Intel Mac). As OpenCore has developed and matured, it has gotten better at bridging larger and larger gaps between PC hardware and "real" Macs. It can get old versions of macOS like Tiger (10.4) and Snow Leopard (10.6) up and running on old hardware, and it can even be used to run newer macOS versions on real Macs that Apple has dropped from the official support list. It can even run macOS on AMD processors, albeit with some caveats for software that relies on Intel-specific functionality. The still-active Hackintosh Reddit community is full of people running macOS on all kinds of different hardware.

It's that sort of flexibility that will keep macOS working on 12th-generation Intel CPUs and the Z690 chipset. All of that said, running macOS on newer hardware isn't for the faint of heart, and some things just aren't going to work. Trying to use 12th-gen processors' new efficiency cores (or E-cores) can also cause general slowdowns because macOS doesn't know how to best distribute work between the different types of cores -- macOS doesn't (and never will) support Intel's "Thread Director" technology, which needs to be baked into your operating system to get the best performance. The GPUs from 11th- and 12th-generation Intel processors also won't work in Hackintoshes because they were never supported in real Macs, so you would need to rely on a dedicated AMD GPU to handle display output and other tasks (in real Intel Macs, even iMacs and MacBook Pros with dedicated GPUs still use the integrated Intel GPUs for video and photo encoding and decoding). Apple is still adding support for newer AMD GPUs in macOS releases, presumably so those cards can work in the Mac Pro -- the Radeon RX 6900 series, 6800 series, and RX 6600 XT are all supported -- but Apple could easily decide to stop supporting newer GPUs whenever it wants. And Nvidia GPUs aren't supported at all.

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.

The global computing power of the bitcoin network has dropped sharply as the shutdown this week of Kazakhstan's internet during a deadly uprising hit the country's fast-growing cryptocurrency mining industry. From a report: Kazakhstan became last year the world's second-largest centre for bitcoin mining after the United States, according to the Cambridge Centre for Alternative Finance, after China clamped down on crypto mining activity. Russia sent paratroopers into Kazakhstan on Thursday to help put down the countrywide uprising after violence spread across the tightly controlled former Soviet state. Police said they had killed dozens of rioters in the main city, Almaty, while state television said 13 members of the security forces had died. The internet was on Wednesday shut down across the country in what monitoring site Netblocks called "a nation-scale internet blackout." The move would have probably prevented Kazakhstan-based miners from accessing the bitcoin network.

"Scientists have never been able to adequately explain where lightning comes from," writes Quanta magazine, sharing a remarkable new animation of a lightning flash recorded by the LOFAR radio telescope network" In a new paper that will soon be published in the journal Geophysical Research Letters, researchers used the observations to settle a long-standing debate about what triggers lightning — the first step in the mysterious process by which bolts arise, grow and propagate to the ground. "It's kind of embarrassing. It's the most energetic process on the planet, we have religions centered around this thing, and we have no idea how it works," said Brian Hare, a lightning researcher at the University of Groningen and a co-author of the new paper....

[T]he electric fields inside clouds are about 10 times too weak to create sparks. "People have been sending balloons, rockets and airplanes into thunderstorms for decades and never seen electric fields anywhere near large enough," said Joseph Dwyer, a physicist at the University of New Hampshire and a co-author on the new paper who has puzzled over the origins of lightning for over two decades. "It's been a real mystery how this gets going." A big impediment is that clouds are opaque; even the best cameras can't peek inside to see the moment of initiation. Until recently, this left scientists little choice but to venture into the storm — something they've been trying since Benjamin Franklin's famous kite experiment of 1752...

LOFAR, a state-of-the-art astronomical telescope, can map lighting on a meter-by-meter scale in three dimensions, and with a frame rate 200 times faster than previous instruments could achieve. "The LOFAR measurements are giving us the first really clear picture of what's happening inside the thunderstorm," said Dwyer...
Long-time Slashdot reader g01d4 summarizes their results: It seems to be something of a chain reaction starting with clusters of [charged] ice crystals inside the cloud... "More electrons flow in from air molecules that are farther away," according to the article, "forming ribbons of ionized air that extend from each ice crystal tip." These are called streamers which build up numbers until one becomes hot and conductive enough to turn into a leader — a channel along which a fully fledged streak of lightning can suddenly travel.
Quanta magazine adds that the key role of ice crystals "dovetails with recent findings that lightning activity dropped by more than 10% during the first three months of the COVID-19 pandemic. Researchers attribute this drop to lockdowns, which led to fewer pollutants in the air, and thus fewer nucleation sites for ice crystals."

Slashdot reader dcblogs writes: Criminal background checks that incorrectly identify an applicant as a thief or sex offender happen more often than many expect. This story reviewed more than 75 lawsuits against background checks firms, spoke with plaintiff attorneys and industry experts to paint a picture of an industry that can ruin lives in minutes. Job applicants are labeled thieves and sex offenders by incorrect reports, and job candidates may protest, but it may not do them any good. Employers may drop them as damaged goods before the correction.
From the article: Some of the errors detailed in lawsuits against background check firms are inexplicable and show a lack of basic attention to detail. Common mistakes include mismatched names and addresses. One background check lawsuit alleged that the first name of Ashley was misidentified as Alysha. In another case, two people with the same first and last name were mixed up despite their distinct middle names: Magdalena and Elena... In another lawsuit, an applicant with a middle name of Scot (one T) was confused with someone whose middle name was Scott (two T's). A background check firm told one job applicant that his Social Security number was in the government's "Death Master File...."
"The candidate may protest. But by then, HR has likely dropped the candidate in an effort to fill an open position," the article points out, offering one example where a corrected background check then arrived, but several weeks later. (The man's lawyer believes it's common for employers to then still refuse to consider an applicaton, simply because "first impressions are everything.")

The article adds that the U.S. Consumer Financial Protection Bureau is now "threatening enforcement actions in concert with the U.S. Federal Trade Commission and Department of Justice." They've already issued an advisory in November calling out "shoddy name matching procedures" used to link people with criminal and other records, and warned that "Even ostensibly low error rates can harm significant numbers of consumers" — especially since more than 90% of U.S. employers use background check data in their hiring processes.

Just over a year after Japan's Hayabusa2 mission returned the first subsurface sample of an asteroid to Earth, scientists have determined that the near-Earth asteroid Ryugu is a pristine remnant from the formation of our solar system. From a report: This was the first material to be returned to Earth from a carbon-rich asteroid. These asteroids can reveal how our cosmic corner of the universe was formed. The organic and hydrated minerals locked within these asteroids could also shed light on the origin of the building blocks of life. Ryugu is a dark, diamond-shaped asteroid that measures about 3,000 feet (1 kilometer) wide. Hayabusa2 collected one sample from the asteroid's surface on February 22, 2019, then fired a copper "bullet" into the asteroid to create a 33-foot wide impact crater. A sample was collected from this crater on July 11, 2019. Then, Hayabusa2 flew by Earth and dropped the sample off in Australia last December.

The C-type, or carbonaceous, asteroid is much darker than scientists originally thought, only reflecting about 2% of the light that hits it, according to one study published Monday in the journal Nature Astronomy. After opening the sample, scientists were surprised to find that the spacecraft collected 5.4 grams from the asteroid -- much more than the single gram they were expecting, said Toru Yada, lead study author and associate senior researcher at the Japan Aerospace Exploration Agency's Institute of Space and Astronautical Science. In the second study, also published Monday in Nature Astronomy, the researchers determined that Ryugu is made of clay and other hydrated minerals, with a number of carbonates and organics inside the sample.

The mosquitofish threatens native fish populations in Australia — including two of the most criticially endangered, reports the New York Times. And in various parts of the world, "For decades scientists have been trying to figure out how to control it, without damaging the surrounding ecosystem.

But in a new lab experiment, "the mosquitofish may have finally met its match: A menacing fish-shaped robot." It's "their worst nightmare," said Giovanni Polverino, a behavioral ecologist at the University of Western Australia and the lead author of a paper published Thursday in iScience, in which scientists designed a simulacrum of the fish's natural predator, the largemouth bass, to strike at the mosquitofish, scaring it away from its prey. The robot not only freaked the mosquitofish out, but scarred them with such lasting anxiety that their reproduction rates dropped; evidence that could have long term implications for the species' viability, according to the paper. "You don't need to kill them," Dr. Polverino said. Instead, he said, "we can basically inject fear into the system, and the fear kills them slowly...."

[S]cientists say there is a long way to go before the robot could be released into the wild. "It's an important proof of concept," said Peter Klimley, a marine biologist and a recently retired professor from the University of California, Davis, who was not involved in the study. But he questioned the feasibility of introducing the creature into a real-world environment.

"This study won't be a solution to the problem," Dr. Polverino said, adding that the next phase of their project would involve testing the robots in a larger, outdoor, freshwater pool. He said the robot should be thought of as a tool that can reveal a pest's weaknesses. "We've built a sort of vulnerability profile," Dr. Polverino said, that could help biologists and others to reimagine how to control invasive species. "This fear," he added, "has a collateral effect."
Their robot fish uses a built-in camera to differentiate between mosquitofish and the native tadpoles it's trying to protect.

"Bitcoin mining is a process of competitively wasting electricity to guess a winning number every 10 minutes or so," writes author David Gerard in Foreign Policy magazine.

And he's got an equally negative take on Salvadoran President Nayib Bukele's experiment in making Bitcoin an official national currency alongside the U.S. dollar. "When a con artist's grift starts to fall apart, he knows to move onto the next one fast..." More than 91 percent of Salvadorans want dollars, not bitcoins. The official Chivo payment system was unreliable at launch in September — the kiss of death for a new system. Users joined for the $30 signup bonus, spent it or cashed it out, then didn't use Chivo again. The system completely failed to check new users' photos, relying solely on their national identity card number and date of birth; massive identity fraud to steal signup bonuses ensued. Bitcoin's ridiculously volatile price was appreciated only by aspiring day traders. Large street protests against compulsory Bitcoin implementation continued through October. The government stopped promoting Chivo on radio, TV, and social media. Chivo buses and vans were seen with plastic taped over the company's logo.

Bukele's financial problems remain. El Salvador can't print its own dollars, so Bukele urgently needs to fund his heavy deficit spending. The International Monetary Fund has not lent the country the $1 billion Bukele asked for, and has indicated its strong concerns about the Bitcoin scheme... At the Latin American Bitcoin and Blockchain Conference on Nov. 20, Bukele came onstage to an animation of beaming down from a flying saucer and outlined his plans for Bitcoin City: a new charter city to be built from scratch, centered on bitcoin mining — and powered by a volcano. Bitcoin City would be paid for with the issuance of $1 billion in "volcano bonds," starting in mid-2022.

The 10-year volcano bonds would pay 6.5 percent annual interest. $500 million of the bond revenue would be used to buy bitcoins... Holding $100,000 in volcano bonds for five years would qualify investors for Salvadoran citizenship... Holders of El Salvador's existing sovereign debt were unimpressed. The volcano bonds would be a strictly worse investment than buying the country's existing bonds and hedging them with bitcoins. The existing bonds dropped from 75 cents on the dollar to a record low of 63.4 cents after the volcano bond announcement...

[T]he volcano bonds are Bukele's way to get Bitcoin holders' money into the Salvadoran economy and count it as dollars. Bukele will brazen all of this out as long as he can, periodically throwing new plans on the table as a distraction. If he can maintain power, then the Bitcoin users will discover that he's taken their money. If he can't maintain power, then his successor will have no love for his failed Bitcoin schemes. Either scenario ends with a lot of disappointed Bitcoin users — because a national economy really can't run on a volatile and manipulated speculative commodity that's unusable as a currency.

Both the Bitcoin users and Bukele seem to think the other is a sucker who they'll take for everything they've got. It's possible that both will lose.
The article also points out that with El Salvador's high electricity rates, one of their power plant recently spent $4,672 in electricity to mine $269 in bitcoin.

NBC News tells the hair-raising tale of Black Oxygen Organics (or "BOO" for short). Put more simply, the product is dirt — four-and-a-half ounces of it, sealed in a sleek black plastic baggie and sold for $110 plus shipping. Visitors to the Black Oxygen Organics website, recently taken offline, were greeted with a pair of white hands cradling cups of dirt like an offering. "A gift from the Ground," it reads. "Drink it. Wear it. Bathe in it." BOO, which "can be taken by anyone at any age, as well as animals," according to the company, claims many benefits and uses, including improved brain function and heart health, and ridding the body of so-called toxins that include heavy metals, pesticides and parasites. By the end of the summer, online ads for BOO had made their way to millions of people within the internet subcultures that embrace fringe supplements, including the mixed martial arts community, anti-vaccine and Covid-denier groups, and finally more general alternative health and fake cure spaces.... "Who would have thought drinking dirt would make me feel so so good?" one person in a 27,000-member private Facebook group posted, her face nuzzling a jar of black liquid....

Teams of sellers in these private Facebook groups claim that, beyond cosmetic applications, BOO can cure everything from autism to cancer to Alzheimer's disease.... But there may be an incentive for the hyperbole... Participation in multi-level marketing (MLM) boomed during the pandemic with 7.7 million Americans working for one in 2020, a 13 percent increase over the previous year, according to the Direct Selling Association, the trade and lobbying group for the MLM industry. Wellness products make up the majority of MLM products, and, as the Federal Trade Commission noted, some direct sellers took advantage of a rush toward so-called natural remedies during the pandemic to boost sales. More than 99 percent of MLM sellers lose money, according to the Consumer Awareness Institute, an industry watchdog group...

The secret to dealing dirt seems to be Facebook, where sellers have created dozens of individual groups that have attracted a hodgepodge of hundreds of thousands of members.
NBC News had a bag analyzed by a professor of soil and environmental science at Ohio State University. It found two doses per day "exceeded Health Canada's limit for lead, and three doses for daily arsenic amounts." Growing concern among BOO sellers about the product — precipitated by an anti-MLM activist who noticed on Google Earth that the bog that sourced BOO's peat appeared to share a border with a landfill — pushed several to take matters into their own hands, sending bags of BOO to labs for testing. The results of three of these tests, viewed by NBC News and confirmed as seemingly reliable by two soil scientists at U.S. universities, again showed elevated levels of lead and arsenic. Those results are the backbone of a federal lawsuit seeking class action status filed in November in Georgia's Northern District court. The complaint, filed on behalf of four Georgia residents who purchased BOO, claims that the company negligently sold a product with "dangerously high levels of toxic heavy metals," which led to physical and economic harm.

Black Oxygen Organics did not respond to requests for comment concerning the complaint.
The anti-MLM forces also formed Facebook groups, monitoring Facebook's pro-Boo sales groups and even documenting sales and company meetings — then filed official complaints with Amreica's product-regulating Federal Trade Commission and the Food and Drug Administration. And it all ended badly for Boo... According to BOO President Carlo Garibaldi, they had weathered the FTC complaints, the FDA seizures, the Health Canada recalls and the online mob. But the "fatal blow" came when their online merchant dropped them as clients....

Members of anti-BOO groups celebrated. "WE DID IT!!!!!!" Ceara Manchester, the group administrator, posted to the "Boo is Woo" Facebook group. "I hope this is proof positive that if the anti-MLM community bans together we can take these companies down. We won't stop with just BOO. A new age of anti-MLM activism has just begun."

In a separate Zoom meeting unattended by executives and shared with NBC News, lower-rung sellers grappled with the sudden closure and the reality that they were out hundreds or thousands of dollars.

"I used to be able to understand 99% of the dialogue in Hollywood films," writes professional film blogger Ben Pearson. "But over the past 10 years or so, I've noticed that percentage has dropped significantly — and it's not due to hearing loss on my end...." Knowing I'm not alone in having these experiences, I reached out to several professional sound editors, designers, and mixers, many of whom have won Oscars for their work on some of Hollywood's biggest films, to get to the bottom of what's going on. One person refused to talk to me, saying it would be "professional suicide" to address this topic on the record. Another agreed to talk, but only under the condition that they remain anonymous. But several others spoke openly about the topic, and it quickly became apparent that this is a familiar subject among the folks in the sound community, since they're the ones who often bear the brunt of complaints about dialogue intelligibility...

"There are a number of root causes," says Mark Mangini, the Academy Award-winning sound designer behind films like "Mad Max: Fury Road" and "Blade Runner 2049." "It's really a gumbo, an accumulation of problems that have been exacerbated over the last 10 years ... that's kind of this time span where all of us in the filmmaking community are noticing that dialogue is harder and harder to understand...."

When it comes to dialogue unintelligibility, one name looms above all others: Christopher Nolan. The director of "Tenet," "Interstellar," and "The Dark Knight Rises" is one of the most successful filmmakers of his generation, and he uses his power to make sure his films push the boundaries of sound design, often resulting in scenes in which audiences literally cannot understand what his characters say. And it's not just audiences who have trouble with some Nolan films: the director has even revealed that other filmmakers have reached out to him to complain about this issue in his movies.... Thomas Curley, who won an Oscar as a production sound mixer on "Whiplash" and previously worked on "The Spectacular Now," has also seen this type of mentality at work. "Not everything really has a very crisp, cinematic sound to it in real life, and I think some of these people are trying to replicate that," he tells me.
Among the other factors: Curley also says that in general there's also a "bit of a fad" with today's actors for "soft delivery or under your breath delivery of some lines." Another sound designer complains today's more-visual movies are more resistant to closely-placed boom microphones — while a sound editor notes issues are exacerbated by compressed shooting schedules. One "high-profile Hollywood sound professional who wishes to remain anonymous even blamed an abundance of new technologies: "more tracks to play with, more options, therefore more expected and asked for from the sound editors... We literally have hundreds of tracks at our disposal."

And after all that, the article adds, movie theaters could also just be showing the movie with volume set too low.

Over 300,000 Android smartphone users have downloaded what turned out to be banking trojans after falling victim to malware that has bypassed detection by the Google Play app store. ZDNet reports: Detailed by cybersecurity researchers at ThreatFabric, the four different forms of malware are delivered to victims via malicious versions of commonly downloaded applications, including document scanners, QR code readers, fitness monitors and cryptocurrency apps. The apps often come with the functions that are advertised in order to avoid users getting suspicious. In each case, the malicious intent of the app is hidden and the process of delivering the malware only begins once the app has been installed, enabling them to bypass Play Store detections.

The most prolific of the four malware families is Anatsa, which has been installed by over 200,000 Android users -- researchers describe it as an "advanced" banking trojan that can steal usernames and passwords, and uses accessibility logging to capture everything shown on the user's screen, while a keylogger allows attackers to record all information entered into the phone. [...] The second most prolific of the malware families detailed by researchers at ThreatFabric is Alien, an Android banking trojan that can also steal two-factor authentication capabilities and which has been active for over a year. The malware has received 95,000 installations via malicious apps in the Play Store. [...] The other two forms of malware that have been dropped using similar methods in recent months are Hydra and Ermac, which have a combined total of at least 15,000 downloads. ThreatFabric has linked Hydra and Ermac to Brunhilda, a cyber-criminal group known to target Android devices with banking malware. Both Hydra and Ermac provide attackers with access to the device required to steal banking information. ThreatFabric has reported all of the malicious apps to Google and they've either already been removed or are under review.

Heidi Thorsen owns the coin-only laundromat "Lunar Laundry" in Seattle — and discovered an odd phenomenon, reports the Seattle Times. "Thorsen went to her bank to replenish her coin supply. But the bank was so short on change, she could only buy a few $10, 40-quarter rolls, and most often there were none at all..."

Thorsen speaks for many in the local coin-operated economy, a diverse, somewhat old-school community of businesses and consumers that has been in a state of agitation since COVID-19 interrupted the normal cycle of coins. "It's something I have to think about all the time," says Queen Anne resident Dan White, whose apartment has a coin-operated laundry. Early in the pandemic, White had to frantically group-text friends to secure enough quarters for a weekend's wash... "People that aren't using quarters for a laundry machine have no idea that this is even happening." Indeed, the Great Quarter Shortage has exposed another social and economic divide as a subset of consumers and businesses must scramble to replace what COVID has made scarce. The result is a kind of two-bit black market, rife with clever workarounds and conspiracy theories, and no small amount of social friction...

Technically, there is no quarter shortage, in Seattle or anywhere. The U.S. Mint produced nearly 24% more coins in 2020 than in 2019, despite a temporary pandemic slowdown, and continues to roll them out at "near record levels," according to Mint officials. The problem, federal officials say, is many of the roughly 55 billion quarters estimated to be in circulation have been stranded by the pandemic in places — under your couch cushions, say, or in your console coin holder — where the coin-operated economy can't touch them. It's a smaller, less visible version of the supply chain crisis, but with quarters instead of cargo containers.

Early in the pandemic, many consumers and businesses stopped using physical currency out of safety concerns. Overall cash purchases in 2020 dropped nearly 27% compared with 2019, while the rate at which coins and bills change hands fell more than 70% — the steepest drop on record — and hasn't recovered, Federal Reserve data show. As coins accumulated in homes and handbags, retailers that were typically quarter-negative even before COVID went even further in the red and made even more frequent coin purchases from banks. Consumers, meanwhile, were also less frequently hauling in their caches of spare change to banks or coin kiosks. As the circulation of coins slowed, and as the reopening economy led banks to order more coins from the Federal Reserve, the country's central bank saw its own coin inventory fall below normal levels. In June 2020, the Reserve imposed a "temporary" restriction on coin orders by private banks that, despite a brief reprieve this year, remains in effect. Some banks restricted their own coin sales, even to big retail customers — and many still do.

The bank is "shorting us on our order a lot," says Dave Garcia, assistant store director at Ballard Market, which, like many retailers, has suspended its own quarter sales to consumers...
It's a problem for the "unbanked" without debit cards and the small-business owners who depend on them and "can't afford to upgrade to digital payments and the touchless economy." (And the article points out this includes laundromats, more than half of which are still coin-operated in the U.S.) The CEO of the Coin Laundry Association even tells the Times that some laundromats have resorted to installing a kill switch on their change machines, just so if noncustomers try to make change, "they just cut the power to the machine."

The owner of the Lunar Laundry ultimately installed a digital system that lets customers pay through a phone app after scanning a washer's QR code. A bar owner in Seattle even believes a conspiracy theory that the government is prolonging the shortage to push everyone to digital currencies so their purchases can all be tracked.

But in fact, the Times notes, "Solving the quarter crisis has become a top priority of the Federal Reserve, where a specially empaneled U.S. Coin Task Force is working to persuade Americans to spend those quarters and other coins back into circulation..."

Illegal miners and mass relocations after a ban on crypto mining in China have overloaded energy grid. From a report: Matthew Heard, a software engineer from San Jose, is worried about his 33 bitcoin mining machines in Kazakhstan. In the past week, they kept getting shut off in an attempt by the national grid to limit the power being used by crypto miners. "It has been days since my machines have been online," he said. "During the last week, even if my machines do come on, they barely stay on." Kazakhstan has been struggling to cope with the huge popularity of crypto mining, driven this year partly by the steep rise in value of cryptocurrencies and partly by a mass migration of miners to its borders after China made mining illegal in May.

After three major power plants in the north of the country went into emergency shutdown last month the state grid operator, Kegoc, warned that it would start rationing power to the 50 crypto miners that are registered with the government, and said they would be "isconnected first" if the grid suffers problems. Heard set up in Kazakhstan in August and his machines are managed by Enegix, a company that rents out space to run crypto mining machines. He said his income has dropped from an average of $1,200 worth of bitcoin per day to $800 in October, and in the past week his machines have only been on for 55 per cent of the time. Machine owners are not notified when shutdowns are going to happen or when they will go back online, he said.

An anonymous reader quotes a report from Ars Technica: Component shortages have been wreaking havoc on the tech industry since the onset of the COVID-19 pandemic, and smartphones are no outlier. Decelerated production schedules have given way to smaller stock and delayed launches. All of this has resulted in a decline in smartphone sales in Q3 of 2021 compared to Q3 2020, Gartner reported today. According to numbers the research firm shared today, sales to consumers dropped 6.8 percent. A deficit in parts like integrated circuits for power management and radio frequency has hurt smartphone production worldwide.

"Despite strong consumer demand, smartphone sales declined due to delayed product launches, longer delivery schedule, and insufficient inventory at the channel," Anshul Gupta, senior research director at Gartner, said in a statement accompanying the announcement. The analyst added that the production schedules of "basic and utility" phones were more affected by supply constraints than "premium" ones. As a result, premium smartphone sales actually increased during this time period, even though smartphone sales overall declined. Still, shoppers were left with limited options, Gartner noted. Samsung ended up winning the greatest market share (20.2 percent), thanks to its foldable smartphones. Apple's quarterly market share (14.2 percent) was aided by new features in its iPhones, namely the A15 processor and improvements to battery life and the camera sensor. Gartner also pointed to interest in 5G.

An anonymous reader quotes a report from The Record: The Emotet malware botnet is back up and running once again almost ten months after an international law enforcement operation took down its command and control servers earlier this year in January. The comeback is surprising because after taking over Emotet's server infrastructure, law enforcement officials also orchestrated a mass-uninstall of the malware from all infected computers on April 25, effectively wiping out the entire botnet across the internet.

[O]ver the weekend, security researcher Luca Ebach said he spotted that another malware botnet named TrickBot was helping the Emotet gang get back on its feet by installing the Emotet malware on systems that had been previously infected with TrickBot. "We used to call this Operation ReachAround back when Emotet was dropped by Trickbot in the past," a spokesperson for Cryptolaemus, a group of security researchers who tracked Emotet in the past, told The Record today. [...]

Cryptolaemus said that right now, the Emotet gang is not sending out any new email spam but relying on the TrickBot gang to help them create an initial footprint of their new botnet incarnation before ramping up spam operations again. But if Emotet's comeback will succeed remains to be seen. It would be very hard for Emotet to reach its previous size any time in the coming months; however, the malware strain itself remains a very sophisticated and capable threat that shouldn't be ignored.

Research studying the possibility of electrifying rail-based freight "finds that the technology is pretty much ready," reports Ars Technica, "and under the right circumstances, the economics are on the verge of working out."

It helps that the price of batteries have dropped 87% over the last decade: In the U.S., the typical freight car travels an average of 241 kilometers per day when in operation. So the researchers created a battery big enough to move that distance as part of a large freight train (four locomotives, 100 freight cars, and about 7,000 tonnes of payload). They found that lithium ferrous phosphate would let each of the four locomotives be serviced by a single freight car configured as a giant battery. The battery would only occupy 40 percent of the volume of a typical boxcar and would be seven tonnes below the weight limit imposed by existing bridges. Because of the efficiency of direct electric power, the train would use only half the energy consumed by an internal combustion engine driving an on-board generator...

Using an economic measure called the "net present value," the researchers determine that switching to batteries alone would cost $15 billion. But taking the pollution damages into account turns the number into a $44 billion savings. Considering climate damages as well boosts the savings to $94 billion. Even if these damages are ignored, a rise in the price of diesel and allowing freight companies to buy power at wholesale rates come close to shifting the costs to neutral... [F]reight companies could use their capacity to provide grid stabilization services or sell back power when the price gets high. In extreme cases, this system could actually pay for the entire infrastructure.

"Preliminary estimates of the most expensive 90 hours per year in the ERCOT [Texas] market, for example, show that batteries could be discharged at $200/kWh, potentially generating enough revenue to pay for the upfront battery cost in a single year," the study says.

In case you missed it, Google officially ended support for its Bookmarks service on September 30, 2021. But fear not, you can still export your bookmarks if you haven't already. Long-time Slashdot reader GPS Pilot writes: Google has dropped support for yet another one of its services. If you're like me, you don't visit Google Bookmarks very often, so you're not aware that Google dropped support on September 30th, 2021. The service still had its uses -- like being able to access a collection of bookmarks across different browsers, or when you're using a strange computer. You can still export your Google bookmarks to alternative services that are "arguably better." Some Google Bookmarks alternatives include Saved, Raindrop, Pinboard, and Mozilla Pocket. Which bookmark manager is your favorite?

Although PCs are still selling at a greater volume than before the COVID-19 pandemic, demand is starting to drop. In Q3 2021, shipments of laptops, desktops, and tablets dropped 2 percent compared to Q3 2020, according to numbers that researcher Canalys shared on Monday. Interest in Chromebooks dropped the most, with a reported decline as high as 36.9 percent. Demand for tablets also fell, showing a 15 percent year-on-year decline, according to Canalys. From a report: Both Canalys and the IDC's Worldwide Quarterly Personal Computing Device Tracker shared Q3 numbers for Chromebooks and tablets on Monday. Canalys said 5.8 million Chromebooks shipped globally during this time, while the IDC said the number was 6.5 million. Both pointed to a huge decline compared to Q3 2020. Canalys reported the drop at 36.9 percent, and IDC pegged it at 29.8 percent. Canalys said that Q3 Chromebook sales took a "major downturn" as the education markets in the US, Japan, and elsewhere became saturated. Demand lessened as government programs supporting remote learning went away, the research group said. After reaching a high of 18 percent market share since the start of 2020, Chromebooks reportedly represented just 9 percent of laptop shipments in Q3 2021.

China is targeting a clean energy goal of reducing fossil fuel use to below 20% by 2060, according to an official plan published by state media. The Guardian reports: The cabinet document, released on Sunday, follows a pledge by President Xi Jinping to wean the world's biggest polluter off coal, with a target of peaking carbon emissions by 2030 and achieving carbon neutrality 30 years later. But the country has been criticized for pushing ahead with opening dozens of new coal-fired power plants. Authorities have also been wanting to ramp up production, with coal prices surging and supplies running low, both factors behind recent power outages. The guidelines come as countries gear up for a new round of climate talks in Glasgow starting on 31 October, from which Xi will be conspicuously absent. China faces a struggle to wean itself off coal, which fuels nearly 60% of its energy-hungry economy.

But on Sunday guidelines published by China's official Xinhua news agency laid out a host of targets in its path towards carbon neutrality. Among them was the proportion of non-fossil fuel consumption reaching about 25% of total energy use by 2030 -- when the nation targets peak emissions. By then, carbon dioxide emissions per unit of GDP would have dropped by more than 65% from 2005 levels, while the total installed capacity of wind and solar power is targeted to reach more than 1,200 gigawatts, Xinhua said. The guidelines also reiterated an earlier aim for carbon emissions per unit of GDP to fall 18% in 2025, from 2020 standards.

The latest version of macOS, Monterey, is now available to download, according to Apple. The software has been available in public beta for several months, but today's release means Apple thinks the software is ready for everyday use. From a report: As is tradition, Apple announced its latest version of macOS at WWDC in June. New features include the ability to set Macs as an AirPlay target to play content from iPhones and iPads, as well as Shortcuts, Apple's iOS automation software. There have also been improvements made to FaceTime, as well as a new Quick Note feature. For a full rundown of what's on the way, check out our preview from July, as well as Apple's own feature list.

Unfortunately, some of Monterey's biggest new additions, Universal Control and SharePlay, don't seem to be available at launch. Apple notes that both features will be available "later this fall." Universal Control allows files to be dragged and dropped between several different machines, as Apple's Craig Federighi demonstrated at WWDC. It also will let you control multiple Apple devices including Macs, MacBooks, and iPads, with the same mouse and keyboard. SharePlay will enable shared experiences of music, TV shows, movies, and more while connected over FaceTime. Once it's available, Apple says you can use the feature with Apple Music, Apple TV+ and unnamed "popular third-party services." It's better news when it comes to Safari's redesign, which by default now uses a more traditional interface rather than the controversial new tab design introduced at WWDC.
