New Studies Argue Distant Cosmic Gamma-Ray Explosion Was Actually Just Russian Space Junk

"Last year, a team of astronomers made a blockbuster claim, saying they had captured the most distant cosmic explosion ever — a gamma ray burst in a galaxy called GN-z11," reports Science magazine. "But that flash of light — supposedly from the most distant galaxy known — has a far more prosaic explanation: It was a glinting reflection from a tumbling, spent Russian rocket that happened to photobomb observers at just the right moment, two new studies claim..." Although they happen all the time, the chances of catching one when a telescope is pointed at a particular galaxy are quite slim. So it was even more surprising when astronomer Linhua Jiang of Peking University and colleagues claimed — using data from the W. M. Keck Observatory in Hawaii — to find a burst coming from GN-z11, a galaxy dating back to a mere 420 million years after the big bang. Indeed, the team itself reported in December 2020 that the odds of catching such a burst were one in 10 billion. Those odds raised red flags for Charles Steinhardt, an astronomer at the University of Copenhagen. "You start asking," he says, "'Are there any other causes that are more likely?'" That's where the Russian rocket comes in. Humans have launched and left behind large numbers of objects in orbit around Earth, including satellites, rocket boosters, and even screwdrivers gone missing during spacewalks. Up to half a million bits of metal larger than 1 centimeter are thought to be tumbling around our planet. Glints of sunlight reflecting off this debris could be responsible for as many as 10,000 flashes of light per hour throughout the night sky, estimates Eran Ofek, an astrophysicist at the Weizmann Institute of Science who has published independent analyses of this phenomenon. The vast majority are invisible to the naked eye, he says, but they can be discernable to astronomical observatories. Given such potential light pollution, the possibility of finding a debris glint in a random telescope image is somewhere between one in 1000 and one in 10,000, Steinhardt and his collaborators calculate in one of the new studies, published today in Nature Astronomy. That seems more likely than the one-in-10-billion chance of a gamma ray burst, Steinhardt says. "If you have to pick between the two answers, yes they're both unlikely, but one of them is millions of times more likely."

Could Bitcoin Mining Really Provide Crucial Demand For Nuclear Power?

Gizmodo takes a hard look at a "growing sense of excitement" about collaboration between bitcoin-mining operations and nuclear power plants (which are now plagued by high operating costs compared to renewables as well as natural gas): Of the three partnerships between bitcoin companies and nuclear energy that the Wall Street Journal mentioned, two involve bitcoin miners partnering with existing nuclear sources to power their operations... These are not companies investing in the future, but rather companies searching for anything that will help keep the profits flowing using existing power plants. It's pretty safe to say that some cash-strapped owners of nuclear plants will be using mining partnerships not to make any technological strides, but rather to simply keep the old plants operating. "The plants themselves are pretty well-run, and they know what they're doing," said Alex Gilbert, a project manager at the think tank Nuclear Innovation Alliance. "It really is a matter of the economics. There's a certain point where you're definitely unprofitable, and you're going to be likely to close because you're not getting enough money in power markets. But if a bitcoin operation takes 10 to 15 to 30 percent of your power at a reasonable price, that tips you into profitability." This profitability means the plants can stay open, giving miners a little carbon-free energy as a treat while keeping the U.S.'s biggest source of zero-emissions power operational. This is especially a good idea while we wait for more renewables — and policies that favor them — to come online, in what could be the first real-world proof bitcoin is doing some societal good instead of being a waste of energy and resources.... A few small-to-medium reactors should be ready for licensing in a few years and some over the next decade, he said, helped along by private and federal funding. To actually get to a point where the kinds of smaller reactors could be developed that would be competitive with the (rapidly falling) price of renewables, Gilbert said, would take a significantly larger bump from private capital — as well as more customers. "Providing early demand for advance reactors, especially microreactors, that's how bitcoin can most help the nuclear sector," he said.... I'm not a technofuturist who dreams of a libertarian paradise, but I have to admit that there's kind of a cool idea here. If the bitcoin community really believes cryptocurrencies are the money of the future, let them be the first to invest in a budding technology that could be the energy of the future. In the interim, however, they shouldn't be allowed to rest on their greenwashing laurels while continuing to churn out emissions as they wait for fast reactor technology to become feasible in 10 years. Government regulations are, of course, anathema to crypto true believers. But a mandate that any new mining facilities source power from nearby nuclear plants could go a long way toward cleaning up bitcoin's act and ensuring the carbon-free energy we desperately need stays on the grid while fancy fast reactors come online.

The Best Part of Windows 11 Is Its Linux, Argues Ars Technica

The best part of Windows 11 is Linux, argues Ars Technica: For years now, Windows 10's Windows Subsystem for Linux has been making life easier for developers, sysadmins, and hobbyists who have one foot in the Windows world and one foot in the Linux world. But WSL, handy as it is, has been hobbled by several things it could not do. Installing WSL has never been as easy as it should be — and getting graphical apps to work has historically been possible but also a pain in the butt that required some fairly obscure third-party software. Windows 11 finally fixes both of those problems. The Windows Subsystem for Linux isn't perfect on Windows 11, but it's a huge improvement over what came before. Microsoft has traditionally made installing WSL more of a hassle than it should be, but the company finally got the process right in Windows 10 build 2004. Just open an elevated Command prompt (start --> type cmd --> click Run as Administrator), type wsl --install at the prompt, and you're good to go. Windows 11, thankfully, carries this process forward unchanged. A simple wsl --install with no further arguments gets you Hyper-V and the other underpinnings of WSL, along with the current version of Ubuntu. If you aren't an Ubuntu fan, you can see what other easily installable distributions are available with the command wsl --list --online. If you decide you'd prefer a different distro, you can install it instead with — for example — wsl --install -d openSUSE-42. If you're not sure which distribution you prefer, don't fret. You can install as many as you like, simply by repeating wsl --list --online to enumerate your options and wsl --install -d distroname to install whichever you like. Installing a second distribution doesn't uninstall the first; it creates a separate environment, independent of any others. You can run as many of these installed environments as you like simultaneously, without fear of one messing up another. In addition to easy installation, WSL on Windows 11 brings support for both graphics and audio in WSL apps. This isn't exactly a first — Microsoft debuted WSLg in April, with Windows 10 Insider Build 21364. But Windows 11 is the first production Windows build with WSLg support. If this is your first time hearing of WSLg, the short version is simple: you can install GUI apps — for example, Firefox — from your Ubuntu (or other distro) command line, and they'll work as expected, including sound. When I installed WSLg on Windows 11 on the Framework laptop, running firefox from the Ubuntu terminal popped up the iconic browser automatically. Heading to YouTube in it worked perfectly, too, with neither frame drops in the video nor glitches in the audio.... [T]here is one obvious "killer app" for WSLg that has us excited — and that's virt-manager, the RedHat-originated virtualization management tool. virt-manager is a simple tool that streamlines the creation, management, and operation of virtual machines using the Linux Kernel Virtual Machine... virt-manager never got a Windows port and seems unlikely to. But it runs under WSLg like a champ. They reported a few problems, like when running GNOME's Software Center app (and the GNOME shell desktop environment). But "If you're already a Windows Subsystem for Linux (WSL) user, Windows 11 offers an enormously improved experience compared to what you're accustomed to from Windows 10. It installs more easily, makes more functionality available, and offers better desktop integration than older workarounds such as running MobaXTerm's X11 server."

With Fewer Chips, Automakers Are Prioritizing High-Markup Vehicles, Offering Fewer Deals

When automakers were forced to make fewer vehicles with the chips they had available, Business Insider reports that "Naturally, they chose to prioritize those models that had the highest demand and made them the most money. "At the same time, the reduction in the supply from all brands meant that dealers could make a sale without the traditional haggling over the vehicle's sticker price. The result has been a boon for automakers." Mark Wakefield, a consultant with AlixPartners in Detroit, told Bloomberg that US car companies were now making $3,000 more per car than average, as well as up to $10,000 more on certain pickups and SUVs. One dealer who sells upgraded pickups in Ohio told Morning Brew that his dealership recently closed a deal in 52 minutes that would have taken four hours before the chip shortage. "The surprising part is the average selling price on those trucks is close to $100,000, and the consumer demand has still been sky-high," the dealer said. Jim Farley, Ford's CEO, said in June that this new pricing power was "breathtaking" and indicated that the company wouldn't be returning to the days of guessing over how many cars it should produce and then marking them down until they sell. Mary Barra, GM's CEO, has also said that customer orders will play a larger role in her company's production strategy. Kevin Tynan, an auto analyst for Bloomberg, told Insider earlier this year that the industry has been trying to get off the incentives and discounting model for decades. "They don't totally hate this," he said, referring to the shortages. "Moving forward you're probably going to get an industry more like what we're seeing now, where supply is a little bit more managed, and incentives are not as aggressive as they've been." The article summarizes the prediction of the Bloomberg auto analyst: "Good news for automakers and investors, but that also means consumers can expect to continue to see fewer options, higher prices, and a tighter used-vehicle market going forward."

Lebanon's National Electricity Grid Collapses

"Lebanon's electricity network collapsed on Saturday," reports the Washington Post, "after the two most important power stations ran out of fuel, leaving private generators as the only source of power." The state-owned electricity company has been providing citizens with just a few hours of power a day for months, but the total collapse of the national grid will compound the misery of those who can't afford to run generators and had relied on those few hours. The outage marks the latest milestone in the unraveling of Lebanon, which is undergoing what the World Bank has described as one of the world's three biggest financial collapses of the past 150 years. The banking system was the first to implode in 2019, triggering a 90 percent slide in the value of the currency that has left the government unable to afford fuel, food and medicine imports while plunging millions of Lebanese into poverty. The electricity grid ground to a halt after the country's two main power stations, Deir Ammar and Zahrani, ran out of diesel fuel, leaving the nationwide network without the minimum amount of power required to sustain it, said Energy Minister Walid Fayyad. The government is working to secure emergency fuel supplies from other sources, including the army, to bridge the shortfall until a shipment of Iraqi oil due to arrive Saturday night can be offloaded and distributed into the network. At most, he said, the total outage can be expected to last only a couple of days, and he hoped to find a stopgap solution faster. But the collapse is a reminder of the dire state of Lebanon's electricity sector, which has been unable to provide 24-hour power for decades. In recent months, its capacity has been further eroded by the lack of money and by corruption, with smugglers diverting state purchases of fuel to sell at a profit in neighboring Syria. A recent deal struck with Iraq to supply 80,000 tons of fuel a month still falls short of the minimum amount required to ensure a stable grid and at most will be able to keep the power on for about four hours a day, Fayyad said.

Python Core Developers Release Version 3.10 -- First Major Release Since Transition from Python 2

ZDNet reports: "Python 3.10.0 is the newest major release of the Python programming language, and it contains many new features and optimizations," CPython maintainers announced in a blogpost... One of the headline features is "structural pattern matching" in Python 3.10 -- a technique for handling data that's already available in C, Java, JavaScript, Scala and Elixir. "Structural pattern matching has been added in the form of a match statement and case statements of patterns with associated actions. Patterns consist of sequences, mappings, primitive data types as well as class instances. Pattern matching enables programs to extract information from complex data types, branch on the structure of data, and apply specific actions based on different forms of data," the project explains in release 3.10 notes. "While structural pattern matching can be used in its simplest form comparing a variable to a literal in a case statement, its true value for Python lies in its handling of the subject's type and shape," it adds. Python core contributors presented the update in a meeting this week. Pablo Galindo Salgado, a physicist and core Python contributor, explained how the project is using Microsoft's GitHub Actions DevOps (CI/CD) tools to test Python changes on Windows, Linux and macOS systems. "When you merge something to Python, there is a CI in GitHub Actions, and we have other providers, although we are mainly using GitHub Actions now. It tests your commits on every single commit on Linux, Windows, and macOS," said Salgado. Besides better error messages (including more precise and reliable line numbers for debugging), other changes to the language include overloading the pipe operator to allow a new syntax for writing union types, and type aliases (a kind of user-specified type, offering a way to explicitly declare an assignment as a type alias).

Beating C and Java, Python Becomes the #1 Most Popular Programming Language, Says TIOBE

ZDNet reports that Python "is now the most popular language, according to one popularity ranking." "For the first time in more than 20 years we have a new leader of the pack..." the TIOBE Index announced this month. "The long-standing hegemony of Java and C is over." When Slashdot reached out to Guido van Rossum for a comment, he replied "I honestly don't know what the appropriate response is...! I am honored, and I want to thank the entire Python community for making Python so successful." ZDNet reports: [I]t seems that Python is winning these days, in part because of the rise of data science and its ecosystem of machine-learning software libraries like NumPy, Pandas, Google's TensorFlow, and Facebook's PyTorch. Python is also an easy-to-learn language that has found a niche in high-end hardware, although less so mobile devices and the web — an issue that Python creator Guido van Rossum hopes to address through performance upgrades he's working on at Microsoft. Tiobe, a Dutch software quality assurance company, has been tracking the popularity of programming languages for the past 20 years. Its rankings are based on search terms related to programming and is one measure of languages that developers should consider learning, along with IEEE Spectrum's list and a ranking produced by developer analyst RedMonk. JavaScript, the default for front-end web development, is always at the top of RedMonk's list. For Tiobe, its enterprise focus, has seen Java and C dominate in recent years, but Python has been snapping at the heels of Java, and has now overtaken it... Python's move to top spot on the Tiobe index was a result of other languages falling in searches rather than Python rising. With an 11.27% share of searches, it was flat, while second place language C fell 5.79% percentage points compared to October last year down to 11.16%. Java made way for Python with a 2.11 percentage point drop to 10.46%. Other languages that made the top 10 in Tiobe's October 2021 index: C++, C#, Visual Basic, JavaScript,. SQL, PHP, and Assemblyy Language. Also rising on a year-on-year basis and in the top 20 were Google-designed Go, number-crunching favorite MATLAB, and Fortran. "Python, which started as a simple scripting language, as an alternative to Perl, has become mature," TIOBE says in announcing its new rankings. "Its ease of learning, its huge amount of libraries, and its widespread use in all kinds of domains, has made it the most popular programming language of today. Congratulations Guido van Rossum!"

Should US Tax Collectors Get Reports From Banks About All Accounts Over $600?

An anonymous reader tipped us off to a proposed new U.S. policy which would require banks, credit unions and other financial companies to submit reports on most of their accounts to the tax-collectors at America's Internal Revenue Service (IRS). The reports "would break down the numbers to include physical-cash transactions per account, any transactions with a foreign account and transactions between accounts held by the same owner," according to the Arizona Republic newspaper. "The IRS wouldn't receive details on individual transactions but, rather, gross yearly totals." America's treasury secretary reiterated that what's being proposed "is not reporting of individual transactions or anything of the like. And it would be a simple thing for banks and other payment providers to provide along with the other information they're already providing." But the Arizona Republic notes the proposal is drawing some concerns — partly because it's been suggested it would cover any account with more than $600: Critics say this would burden financial institutions with new requirements and expose consumers and businesses to privacy incursions and possible data breaches. Supporters contend bank customers would face no new obligations while giving the IRS more information to pursue tax cheats, primarily among the wealthy. They hope to close a tax gap estimated at around $600 billion annually... The $600 figure isn't set in stone. Some media reports have indicated it could be increased to, say, $10,000 — the level at which banks report transactions in an effort to combat money laundering. A Treasury summary of the plan indicated there would be no further recordkeeping or reporting requirements for individuals or businesses and that taxpayers wouldn't face any burdens at all. The Treasury also noted banks and other financial providers already have access to this information and already report interest income above $10... About 15% of the money owed the federal government isn't collected, according to Natasha Sarin, a deputy assistant secretary at the Treasury Department... Just knowing the IRS would have access to some bank-account details might convince more taxpayers to pay what they owe. The deputy assistant secretary argues there's a direct relationship between the information the IRS has and a taxpayer's voluntary compliance rate. "For ordinary wage and salary income, compliance with income tax liabilities is nearly perfect (1 percent noncompliance rate). In stark contrast, for opaque income sources that accrue disproportionately to higher earners...noncompliance can reach 55 percent...." "Today's tax code contains two sets of rules: one for regular wage and salary workers who report virtually all the income they earn; and another for wealthy taxpayers"

New Data: Tech Companies Expand Hiring From 'Tech Hubs' to 'All Over The Place'

"Just two years ago the metropolitan areas that serve as the nation's technology hubs seemed to be sucking tech jobs away from other parts of the country," remembers business writer Peter Coy in the New York Times. "A Brookings Institution report in December 2019 noted that just five cities — Boston, San Diego, San Francisco, Seattle and San Jose, Calif. — accounted for more than 90 percent of employment growth in the innovation sector from 2005 to 2017. "The trend is now in the other direction: The tech hubs' share of employment is falling." This development was already starting in 2019, and the Covid-19 pandemic has accelerated it. Newspapers are full of stories about Silicon Valley tech workers moving to parts of the country where the housing is cheaper and the fishing is better... Employers seem to be benefiting from the trend: Mark Muro, a Brookings senior fellow, told The Wall Street Journal in July that tech companies, by letting people work outside their home offices, can "truly access lost Einsteins all across the country." The evidence for this shift used to be mostly anecdotal. Now there's hard data. It comes from the Conference Board, a business-supported research organization. Gad Levanon, the founder of the board's Labor Market Institute, gave me a preview of data he has collected using software that tracks almost all the online want ads in the United States. He focused on ads placed by tech employers based in five tech hubs — the same five as those surveyed by Brookings in 2019, except with Los Angeles in place of Boston. His findings? "West Coast tech companies are dramatically shifting their hiring to other parts of the U.S.," Levanon wrote to me in an email. "Not just for tech jobs, but also engineers, scientists, managers, business and financial professionals." Levanon also analyzed the data according to where new jobs are being offered. "They are moving to all over the place," he wrote me. Some of the jobs, he explained, are in metropolitan areas where the employers were already established — such as New York, Washington, Boston and Austin, Texas. "But some of the shift," he said, "is to areas where they barely hired before" — like Boise, Idaho, and Des Moines, Iowa. Because of the pandemic, employers have gotten more comfortable with hiring people who don't work at their companies' headquarters, Levanon says. Some new hires may be working at home while others are in satellite offices. Casting the net wider gives companies access to more talent — including people who may work for lower salaries because their living costs are cheaper elsewhere.

US Flight Traffic Controllers Complain Military Tests Interfered with GPS Signals

IEEE Spectrum reports that air traffic controllers for America's Federal Aviation Administration "were confused and frustrated by an increase in military tests that interfered with GPS signals for civilian aircraft, public records show." The incidents happened for controllers supervising flights over Arizona, New Mexico and Texas, according to their report (shared by Slashdot reader schwit1): In March and April this year, flight controllers at the Albuquerque Air Route Traffic Control Center filed reports on NASA's Aviation Safety Reporting System (ASRS), a forum where aviation professionals can anonymously share near misses and safety tips. The complaints accused the FAA of denying controllers permission to ask the military to cut short GPS tests adversely affecting commercial and private aircraft. These so-called "stop buzzer" (or "cease buzzer") requests are supposed to be made by pilots only when a safety-of-flight issue is encountered. "Aircraft are greatly affected by the GPS jamming and it's not taken seriously by management," reads one report. "We've been told we can't ask to stop jamming, and to just put everyone on headings." In a second report, a private jet made a wrong turn into restricted airspace over the White Sands Missile Range in New Mexico after being jammed. On that occasion, the air traffic controller called a stop buzzer. "[The] facility manager on duty later informed me we can't ask them to 'stop buzzer' and to just keep putting aircraft on headings," their ASRS report reads. Putting an aircraft on headings requires giving pilots precise bearings to follow, rather than letting them perform their own navigation using GPS or other technologies. This adds work for controllers, who are already very busy at certain times of day... The Pentagon uses its more remote military bases, many in the American West, to test how its forces operate under GPS denial. A Spectrum investigation earlier this year discovered that such jamming tests are far more prevalent than had previously been thought, possibly affecting thousands of civilian flights each year.

Former Employees Allege Most of Ozy's 26M Newsletter Subscribers Were Purchased, Borrowed, or Kept Against Their Will

Eight days ago Ozy announced it was shutting down after reports that the news site bought traffic, overstated its cable deals, and at one point even had its Chief Operating Officer impersonate a YouTube executive during a phone call with investors. Then four days ago, Ozy's CEO said he planned to relaunch the company's newsletters (while looking for new board members) to try to instead revive the company. "Ozy Media boasts that it has more than 26 million subscribers for its newsletters," reports Forbes... "But former employees say this is another example of deceptive tactics at the embattled digital media company, with most of the email addresses on its newsletter lists either purchased, taken from other companies without their permission or added back to the lists after the recipients unsubscribed — a potentially illegal act." Three ex-employees with knowledge of Ozy's newsletter operations, who asked to remain anonymous because of non-disclosure agreements they signed, said the company on multiple occasions obtained large numbers of email addresses through marketing partnerships it formed with other companies and news outlets. Ozy would offer to send an email for the other company as part of the partnership, and some companies would then share a list of addresses for a supposed one-time message. Instead, the former employees allege, those email addresses would then be permanently added to Ozy's newsletter subscriber list. Among the companies they say Ozy collectively accumulated millions of email addresses from were the McClatchy newspaper chain and the technology magazine Wired, according to two of the former employees. Ozy would also buy in bulk email addresses from third-party websites like U.S. Data Corporation and Exact Data, ramping up the size of its newsletter following in order to fulfill advertising deals with its clients. After Ozy added batches of new addresses to its mailing lists, many recipients would attempt to unsubscribe from the newsletters only to be kept on the distribution lists and even re-subscribed under the direction of Ozy management, a potential violation of commercial email laws... Despite a "very small" organic audience and low engagement numbers, according to a source with knowledge of Ozy's newsletter audience, Ozy sent a pitch deck to investors over the summer for its Series D funding round that claimed it was achieving an email open rate of 25%, or (in Ozy's words): "2.5x the industry standard." Ozy founder and CEO Carlos Watson admitted that number was exaggerated during a Monday interview with CNBC, claiming it instead represents the engagement rate among Ozy's "best, most regular people." Watson still claimed this subset of Ozy's audience is between 10 and 12 million people. Forbes adds that there was no response to their request for a comment from Ozy, McClatchy, and Wired's parent company Conde Nast.

US Government Investigators Still Believe Havana Syndrome is a Directed-Energy Attack

The U.S. government's investigation into Havana Syndrome "is turning up new evidence that the symptoms are the result of directed-energy attacks," reports Politico, citing five U.S. lawmakers and officials who've been briefed on the matter: Behind closed doors, lawmakers are also growing increasingly confident that Russia or another hostile foreign government is behind the suspected attacks, based on regular briefings from administration officials — although there is still no smoking gun linking the incidents to Moscow.... The phenomenon is getting more high-level attention as government officials have continued to report incidents in countries across Europe, Asia, Africa and South America throughout the year. Most prominently, Vice President Kamala Harris' August trip from Singapore to Vietnam was delayed more than three hours when multiple U.S. personnel reported symptoms consistent with Havana Syndrome in Hanoi... A Biden administration official emphasized that the investigation is ongoing and has not yet reached specific conclusions... While CIA Director William Burns and lawmakers briefed on the matter have publicly referred to the incidents as attacks, some officials remain skeptical of the prevailing theory, and some prominent neurologists have described that explanation as implausible. But members of the Senate Intelligence Committee, who are receiving weekly updates from the intelligence community on the status of the investigation, said the latest information they've received has disproved the skeptics — and in public statements, those lawmakers are increasingly referring to the incidents as directed-energy attacks. Politico quotes one Republican Senator as saying "There have been new additional attacks, which is very disturbing. It's being taken very seriously now due to the director of the CIA ... [who] has put very highly qualified people on it..." The Senator also dismissed the theory that the illness was merely psychosomatic. "I don't know how you could argue that when brain imaging is showing a traumatic brain injury, somehow this is psychosomatic."

Did Death Cheat Stephen Hawking of a Nobel Prize?

"Did death cheat Stephen Hawking of a Nobel Prize?" asks the New York Times: When the iconic physicist died on March 14, 2018, data was already in hand that could confirm an ominous and far-reaching prediction he had made more than four decades before. Dr. Hawking had posited that black holes, those maws of gravitational doom, could only grow larger, never smaller — swallowing information as they went and so threatening our ability to trace the history of the universe. That data was obtained in 2015 when the Laser Interferometer Gravitational-Wave Observatory, or LIGO, recorded signals from two massive black holes that had collided and created an even more massive black hole. Dr. Hawking's prediction was a first crucial step in a series of insights about black holes that have transformed modern physics. At stake is whether Einsteinian gravity, which shapes the larger universe, plays by the same rules as quantum mechanics, the paradoxical rules that prevail inside the atom. A confirmation of Dr. Hawking's prediction was published this summer in Physical Review Letters. A team led by Maximiliano Isi, a physicist at the Massachusetts Institute of Technology, and his colleagues had spent years digging into the details of the LIGO results, and in July they finally announced that Dr. Hawking was right, at least for this particular black hole collision. "It's an exciting test because it's a long-desired result that cannot be achieved in a lab on Earth," Matthew Giesler, a researcher at Cornell University and part of Dr. Isi's team, said in an email. "This test required studying the merger of two black holes over a billion light years away and simply could not be accomplished without LIGO and its unprecedented detectors." Nobody claims to know the mind of the Nobel Prize committee, and the names of people nominated for the prize are held secret for another 50 years. But many scientists agree that Dr. Isi's confirmation of Dr. Hawking's prediction could have made Dr. Hawking — and his co-authors on a definitive paper about it — eligible for a Nobel Prize. But the Nobel Prize cannot be awarded posthumously. Dr. Isi's result came too late.

3 Degrees Warmer, with Twice as Many 100-Degree Days: How Climate Change Will Affect Texas

The Texas Tribune (an Austin-based non-profit digital news site) reports that climate change "has made the Texas heat worse, with less relief as nighttime temperatures warm, a report from the state's climatologist published Thursday found." Climate data also show that the state is experiencing extreme rainfall — especially in eastern Texas — bigger storm surges as seas rise along the Gulf Coast and more flooding from hurricanes strengthened by a warming ocean, the report says. Those trends are expected to accelerate in the next 15 years, according to the report, which analyzes extreme weather risks for the state and was last updated in 2019. The report was funded in part by Texas 2036, a nonpartisan economic policy nonprofit group named for the state's upcoming bicentennial. The average annual temperature in Texas is expected to be 3 degrees warmer by 2036 than the average of the 1950s, the report found. The number of 100-degree days is expected to nearly double compared with 2000-2018, especially in urban areas. "From here on out, it's going to be very unusual that we ever have a year as mild as a typical year during the 20th century," said John Nielsen-Gammon, the Texas state climatologist who authored the report. "Just about all of them are going to be warmer." A hotter Texas will threaten public health, squeeze the state's water supply, strain the electric grid and push more species toward extinction, experts told The Texas Tribune... The entire baseline of temperatures in the state has shifted upward — a trend that is likely to continue to cause problems for the state's aging infrastructure, experts said. "I was surprised at how strong the upward trend was in the coldest temperatures of the summer," Nielsen-Gammon said. While global temperature analysis had already shown that trend, he said, it is now very clearly happening on the local level in Texas. Even this year, which was considered a mild year because Texas didn't see temperatures above 100 degrees in much of the state, Nielsen-Gammon said nighttime temperatures stayed warm enough to put 2021 in the top 20% of years with the hottest summer nights on record.

FSF Warns Windows 11 'Deprives Users of Freedom and Digital Autonomy'

"October 5 marks the official release of Windows 11, a new version of the operating system that doesn't do anything at all to counteract Windows' long history of depriving users of freedom and digital autonomy," writes Free Software Foundation campaigns manager Greg Farough. "While we might have been encouraged by Microsoft's vague, aspirational slogans about community and togetherness, Windows 11 takes important steps in the wrong direction when it comes to user freedom." Microsoft claims that "life's better together" in their advertising for this latest Windows version, but when it comes to technology, there is no surer way of keeping users divided and powerless than nonfree softwarechoosing to create an unjust power structure, in which a developer knowingly keeps users powerless and dependent by withholding information. Increasingly, this involves not only withholding the source code itself, but even basic information on how the software works: what it's really doing, what it's collecting, and how often it's snitching on users. "Snitching" may sound dramatic, but Windows 11 will now require a Microsoft account to be connected to every user account, granting them the ability to correlate user behavior with one's personal identity. Even those who think they have nothing to hide should be wary of sharing potentially all of their computing activity with any company, much less one with a track record of abuse like Microsoft... We expect Microsoft to use its tighter control on cryptography that happens in Windows as a way to impose more severe Digital Restrictions Management (DRM) onto media and applications, and as a way to ensure that no application can run in Windows without Microsoft's approval. In cases like these, it's no longer appropriate to call a machine running Windows a "personal" computer, as it obeys Microsoft more than it does its user. Indeed, it's bitterly ironic that Microsoft is calling the program that verifies a system's compatibility with Windows 11 a "PC Health Check." We counter that a healthy PC is one that respects its user's wishes, runs free software, and doesn't purposefully restrict them through treacherous computing. It would also never send the user's encryption keys back to its corporate overlords. Intrepid users will likely find a way around this requirement, yet it doesn't change the fact that the majority of Windows users will be forced into a treacherous computing scheme... Sometimes, Microsoft realizes that it can't be quite so overtly antisocial. We've commented many times before on the hypocrisy involved in saying that Microsoft "loves open source" and "loves Linux," two ways of mentioning free software without reference to freedom. At the same time, Microsoft employees do make contributions to free software, contributions which benefit many others. Yet they do not extend this philosophy to their operating system, and in the last few years, they've made an attempt to impair the ways free software makes "life better together" further by making critical functions of Microsoft GitHub rely on nonfree JavaScript and directing users toward Service as a Software Substitute (SaaSS) platforms. By attacking user freedom through Windows, and the free software community directly by means of nonfree JavaScript, Microsoft proves that it has no plans to loosen its grip on users. No program that you're forbidden to copy, modify, or share can truly bring people "together" in the way that Microsoft claims. Thankfully, and right outside the window, there's a true community of users you and your loved ones can join... Let's stop falling for the trap of chasing short-term, superficial improvements in proprietary software that may seem to make life better, and instead opt for free software, the only software that can support the best versions of ourselves. The post urges readers to sign (or renew!) their pledge not to use Windows and to help a friend install GNU/Linux, "sending Microsoft the strong message that software that subjugates its users has no place in Windows.... If you don't feel ready to take the plunge and switch entirely, you can use our resources like the Free Software Directory to find programs you can use as starting points for your free software journey." The post also has harsh words for TPM, warning that "when it's deployed by a proprietary software company, its relationship to the user isn't one based on trust, but based on treachery. When fully controlled by the user, TPM can be a useful way to strengthen encryption and user privacy, but when it's in the hands of Microsoft, we're not optimistic." And when it comes to Microsoft teams, "it seems that no Windows user can avoid it any longer.... we hope Teams' unpopularity and its newfound, unwanted place in Windows will encourage users to seek out conferencing programs that they themselves can control."

Firefox Now Sends Your Address Bar Keystrokes To Mozilla

✇Slashdot
著者: BeauHD
An anonymous reader quotes a report from How-To Geek: Firefox now sends more data than you might think to Mozilla. To power Firefox Suggest, Firefox sends the keystrokes you type into your address bar, your location information, and more to Mozilla's servers. Here's exactly what Firefox is sharing and how to control it. This change was made as part of the introduction of Firefox Suggest in Firefox 93, released on October 5, 2021. As part of Firefox Suggest, Firefox is getting ads in your search bar -- but that's not the only thing that will be news to longtime Firefox users. According to Mozilla, "Firefox Suggest acts as a trustworthy guide to the better web, surfacing relevant information and sites to help people accomplish their goals." In reality, what that means is, when you start typing in your address bar, you won't just see the standard search suggestions from Google or your current search default engine. You'll also see "Firefox Suggest" results pointing to web pages. Some of them are sponsored ads, but you can disable the ads. Firefox Suggest is on by default. Mozilla's blog post on the subject says Firefox Suggest is an "opt-in experience," which was the case in September 2021 -- but it's now enabled by default in Firefox 93. However, as of Firefox 93's release in October 2021, Firefox Suggest is only enabled in the USA -- for now. It's worth noting that, for many years, Firefox and other web browsers have had search suggestions in their address bar. So, when you start typing "win" in your address bar, you may see suggestions for "Windows 11" and "Window repair." This is accomplished by sending keystrokes to your default search engine as you type in the search bar, as Mozilla's support site explains. Mozilla is also providing contextual suggestions, for which it needs more data, including the city you're located in and whether you're clicking its suggestions. You can disable Firefox's suggested results, if you like. This will stop Mozilla from collecting the data you type in your search bar, and it will also disable the suggested results and ads. To do so, open Firefox and click menu [and then] Settings. Select "Privacy [and] Security" in the left pane, and scroll down to "Address Bar -- Firefox Suggest." Disable "Contextual suggestions" and "Include occasional sponsored suggestions" to stop Firefox from sending data to Mozilla.

PC Building Simulator Is Free On the Epic Games Store

著者: BeauHD
PC Building Simulator is currently free on the Epic Games Store until October 17th. The Verge reports: Like the majority of sim games, PCBS speaks to a very specific type of fantasy. If your idea of a good time is overclocking your computer while managing a small business, this is a game that does exactly that. My favorite feature has to be making your work computer in-game look exactly like your computer IRL. The game will even adjust the RGB lighting and wallpaper of your machine to match. However, depending on your level of experience, the game can actually serve as a worthwhile educational tool for anyone who wants to learn more about... well, building PCs. PC Building Simulator has received its fair share of DLC, mostly in the form of different workshop environments that are entirely cosmetic. However, it did get an esports expansion that's a little more narrative-focused and plays more like a timed puzzle game rather than a business simulation. It's also worth noting that the game regularly receives free updates that add new hardware to the already massive roster of cases, CPUs, GPUs, and other bits and bobs. There are really only two things this game doesn't simulate: misplacing that last thumbscrew and getting thermal paste on absolutely everything.

Astronaut Spots Rare and Ethereal 'Transient Luminous Event' From ISS

"Transient luminous event" sounds like a euphemism for a ghost, but it's actually a beautiful phenomenon that can sometimes be seen from the International Space Station. European Space Agency astronaut and current ISS resident Thomas Pesquet shared a view of an ethereal blue glow emerging over Europe. CNET reports: Transient luminous events are caused by upper-atmospheric lightning. This one happened in early September and Pesquet tweeted about it this week, calling it "a very rare occurrence." "What is fascinating about this lightning is that just a few decades ago they had been observed anecdotally by pilots and scientists were not convinced they actually existed," Pesquet said on Flickr. "Fast forward a few years and we can confirm elves, and sprites are very real and could be influencing our climate too!" Pesquet's image represents a single frame from a time-lapse taken from the station. The image would be a beauty just for the way it shows the curve of Earth and the twinkling lights of Europe below. The transient luminous event captured at its finest moment takes it to the next level.

White House Weighs Wide-Ranging Push For Crypto Oversight

✇Slashdot
著者: BeauHD
An anonymous reader quotes a report from Bloomberg: The Biden administration is weighing an executive order on cryptocurrencies as part of an effort to set up a government-wide approach to the white-hot asset class, according to people familiar with the matter. The proposed directive would charge federal agencies to study and offer recommendations on relevant areas of crypto -- touching on financial regulation, economic innovation and national security. The initiative will also aim to coordinate agencies' work on digital currencies throughout the executive branch. The plan would push departments that have given scant attention to crypto to focus on it. Officials have also considered appointing a White House crypto czar to act as a point person on the issue, one person said. The draft directive is part of an effort by the White House to craft a sweeping strategy for digital tokens, which have become a growing concern for regulators as they've become wildly popular with average Americans. No decision has been made on whether to release the executive order, two of the people said. Even if President Joe Biden doesn't move forward on it, the administration will still make public its overall strategy for cryptocurrencies, an administration official said. [...] The draft, which has been circulating among senior officials and regulators, would clarify the responsibilities of various agencies and task them with examining relevant topics and reporting back on their findings. The framework would touch a range of bureaucracies, from the Treasury Department and financial regulators to the Commerce Department, the National Science Foundation and national security agencies. Whether it's ultimately done by executive order or another means, the goal of the White House is to take a unified approach to crypto, rather than the more ad hoc approach to financial stability, national security and illicit finance issues during Biden's first nine months in office. The administration also wants relevant agencies to examine crypto in other policy areas, including consumer protection, competition policy, research and innovation, the official said.

Neuroscientists Roll Out First Comprehensive Atlas of Brain Cells

✇Slashdot
著者: BeauHD
A slew of 17 studies reveals the first comprehensive list of all cell types in the primary motor complex, offering "a starting point for tracing cellular networks to understand how they control our body and mind and how they are disrupted in mental and physical disorders," reports ScienceDaily. From the report: The 17 studies, appearing online Oct. 6 in the journal Nature, are the result of five years of work by a huge consortium of researchers supported by the National Institutes of Health's Brain Research Through Advancing Innovative Neurotechnologies (BRAIN) Initiative to identify the myriad of different cell types in one portion of the brain. It is the first step in a long-term project to generate an atlas of the entire brain to help understand how the neural networks in our head control our body and mind and how they are disrupted in cases of mental and physical problems. [...] Individual researchers have previously identified dozens of cell types based on their shape, size, electrical properties and which genes are expressed in them. The new studies identify about five times more cell types, though many are subtypes of well-known cell types. For example, cells that release specific neurotransmitters, like gamma-aminobutyric acid (GABA) or glutamate, each have more than a dozen subtypes distinguishable from one another by their gene expression and electrical firing patterns. While the current papers address only the motor cortex, the BRAIN Initiative Cell Census Network (BICCN) -- created in 2017 -- endeavors to map all the different cell types throughout the brain, which consists of more than 160 billion individual cells, both neurons and support cells called glia. The BRAIN Initiative was launched in 2013 by then-President Barack Obama. [Researchers] have already used CRISPR-Cas9 to create mice in which a specific cell type is labeled with a fluorescent marker, allowing them to track the connections these cells make throughout the brain. For the flagship journal paper, the Berkeley team created two strains of "knock-in" reporter mice that provided novel tools for illuminating the connections of the newly identified cell types. "The big advance by the BICCN is that we combined many different ways of defining a cell type and integrated them to come up with a consensus taxonomy that's not just based on gene expression or on physiology or morphology, but takes all of those properties into account," [UC Berkeley colleague Dirk Hockemeyer] said. "So, now we can say this particular cell type expresses these genes, has this morphology, has these physiological properties, and is located in this particular region of the cortex. So, you have a much deeper, granular understanding of what that cell type is and its basic properties." [F]uture studies could show that the number of cell types identified in the motor cortex is an overestimate, but the current studies are a good start in assembling a cell atlas of the whole brain.
