"The Register reports Microsoft fixed a Point of Sale bug that delayed Windows 11 startup for 40 minutes," writes Slashdot reader ellithligraw. "So much for the express lane at check-out." From the report: A fresh Windows 11 patch slipped out overnight as an optional update, but contains an impressively long list of fixes for Microsoft's flagship operating system. One bug addressed in KB5012643 could leave Point of Sale terminals hanging for up to 40 minutes during startup. Microsoft stated, "We fixed an issue that delays OS startup by approximately 40 minutes." "Microsoft described the fixes as 'improvements' [and chose to highlight the fact that temperature would now be displayed on top of the weather icon on the taskbar]," added Slashdot reader ellithligraw. "[Y]eah, Windows 11 is great as a PoS."

Space rocks that fell to Earth within the last century contain the five bases that store information in DNA and RNA, scientists report April 26 in Nature Communications. Science News reports: These "nucleobases" -- adenine, guanine, cytosine, thymine and uracil -- combine with sugars and phosphates to make up the genetic code of all life on Earth. Whether these basic ingredients for life first came from space or instead formed in a warm soup of earthly chemistry is still not known. But the discovery adds to evidence that suggests life's precursors originally came from space, the researchers say. Scientists have detected bits of adenine, guanine and other organic compounds in meteorites since the 1960s. Researchers have also seen hints of uracil, but cytosine and thymine remained elusive, until now.

An anonymous reader quotes a report from NPR: Is polio making a comeback? The world has spent billions of dollars over the last 15 years in an effort to wipe out the virus through vaccination efforts -- with encouraging results. Rates plunged from an estimated 350,000 cases in 1988 to just several dozen by 2016. But in recent years, polio incidence has started to inch back up. The reason has to do with the type of vaccine used in many parts of the world, primarily in low- and middle-income countries. While the United States and other Western countries inject an inactivated virus that poses no risk of spread and are now polio-free, other countries rely on an oral vaccine. It's cheap, it's easy to administer and two or more doses confer lifelong immunity. But it's made with living, weakened virus. And that poses a problem. Those who've been immunized with live virus can shed it in their stool, which can then spread through sewage in places with poor sanitation. If the virus stays weak, it can even expose the unvaccinated to polio and give them immunity. But if it mutates and regains virulence, someone who isn't vaccinated can become sick with vaccine-derived polio after contact with the contaminated wastewater. And now countries that had previously eradicated polio in Africa, the Middle East and parts of Asia are seeing new outbreaks of vaccine-derived polio. One reason for this rise in cases, say polio experts, is that gaps in immunization in recent years have created more opportunities for the unvaccinated to become infected. "Vaccination campaigns have been certainly affected by the pandemic," says Raul Andino, a virologist at University of California, San Francisco. [...] The composition of the oral vaccine has also been a factor. In 2016, eyeing an uptick in vaccine-derived polio, global health officials altered the composition of the oral vaccine. Previously, the vaccine protected against all three types of wild polio -- the virus that circulates naturally in the environment. Then they withdrew one of those types -- the one that was leading to most of the vaccine-derived cases but whose wild form had been successfully eradicated. Only there was a development that hadn't been anticipated. Vaccine-derived poliovirus of that type was still in circulation from earlier iterations of the oral vaccine -- and now with the reformulated vaccine, increasing numbers of people who were no longer vaccinated against it. So there was further spread. Thankfully, a new kind of vaccine being rolled out is showing promise. "The novel vaccine still contains a weakened version of the virus, but it's been hobbled even further," reports NPR. "The researchers tweaked the virus so that it has to accumulate more mutations to become virulent and has a harder time amassing those mutations. For example, they've altered the polymerase, one of the key enzymes responsible for introducing mutations, reducing its ability to mix and match genes from different viruses."

MIT engineers have developed a paper-thin loudspeaker that can turn any surface into an active audio source. MIT News reports: This thin-film loudspeaker produces sound with minimal distortion while using a fraction of the energy required by a traditional loudspeaker. The hand-sized loudspeaker the team demonstrated, which weighs about as much as a dime, can generate high-quality sound no matter what surface the film is bonded to. To achieve these properties, the researchers pioneered a deceptively simple fabrication technique, which requires only three basic steps and can be scaled up to produce ultrathin loudspeakers large enough to cover the inside of an automobile or to wallpaper a room. A typical loudspeaker found in headphones or an audio system uses electric current inputs that pass through a coil of wire that generates a magnetic field, which moves a speaker membrane, that moves the air above it, that makes the sound we hear. By contrast, the new loudspeaker simplifies the speaker design by using a thin film of a shaped piezoelectric material that moves when voltage is applied over it, which moves the air above it and generates sound. [...] They tested their thin-film loudspeaker by mounting it to a wall 30 centimeters from a microphone to measure the sound pressure level, recorded in decibels. When 25 volts of electricity were passed through the device at 1 kilohertz (a rate of 1,000 cycles per second), the speaker produced high-quality sound at conversational levels of 66 decibels. At 10 kilohertz, the sound pressure level increased to 86 decibels, about the same volume level as city traffic. The energy-efficient device only requires about 100 milliwatts of power per square meter of speaker area. By contrast, an average home speaker might consume more than 1 watt of power to generate similar sound pressure at a comparable distance. The researchers showed the speaker in action, playing "We Are the Champions" by Queen. You can listen to it here.

The Central African Republic (CAR) has approved Bitcoin as legal tender -- just the second country to do so. The BBC reports: CAR is one of the world's poorest countries, but is rich in diamonds, gold and uranium. It has been wracked by conflict for decades and is a close Russian ally, with mercenaries from the Wagner Group helping fight rebel forces. Lawmakers voted unanimously to adopt Bitcoin as legal tender, said a statement from the CAR presidency. The move puts CAR "on the map of the world's boldest and most visionary countries", it said. El Salvador became the first country to adopt Bitcoin as an official currency in September 2021 - a move criticized by many economists, including the International Monetary Fund, which said it increased the risk of financial instability. Others have raised fears that cryptocurrencies such as Bitcoin could make it easier for criminals to launder money, and that they are environmentally damaging because they use so much electricity to generate.

On Monday, the world's largest plant for making silicon carbide chips was opened in central New York. Nikkei Asia reports: The $1 billion, 63,000 sq. meter fabrication plant, or "fab," will be the first of its kind to make 200mm silicon carbide wafers, according to [North Carolina-based Wolfspeed]. Silicon carbide, or SiC, is an alternative to traditional silicon that is gaining popularity due to its energy efficiency when transferring power, something especially useful in electric vehicle manufacturing. Ahead of the fab opening, Wolfspeed announced a partnership with luxury EV maker Lucid Motors. It also has agreements with General Motors and China's Yutong Group to supply silicon carbide chips for their electric vehicles. The U.S. share of modern semiconductor manufacturing capacity has declined to 12% from 37% in 1990, according to the Semiconductor Industry Association, a group that has lobbied for the CHIPS Act. This trend, the group says, is largely due to a lack of government investment compared to other nations. [...] In New York, there are hopes that other plants will cluster around the Wolfspeed fab. Wolfspeed received $500 million in construction subsidies from New York as the state seeks to expand its semiconductor manufacturing industry, which has generated nearly $6 billion a year in economic impact and over 34,000 jobs, according to [New York Gov. Kathy Hochul]. The grand opening of a modern manufacturing facility has a special resonance in central New York. The fab stands in the Mohawk Valley, an area along the Erie Canal that was once filled with traditional industry but long ago slid into an economic decline that has defined the region in recent times. So far the Wolfspeed facility has created 265 jobs, with a goal of over 600 new jobs by 2029, according to the company. The site sits directly across from a campus of SUNY Polytechnic Institute, New York's public polytechnic college, and Wolfspeed has given the school $250,000 to help train potential future employees.

The US Army could end up wasting much as $22 billion in taxpayer cash if soldiers aren't actually interested in using, or able to use as intended, the Microsoft HoloLens headsets it said it would purchase, a government watchdog has warned. The Register reports: In 2018, the American military splashed $480 million on 100,000 prototype augmented-reality goggles from Redmond to see how they could help soldiers train for and fight in combat. The Integrated Visual Augmentation System (IVAS) project was expanded when the Army decided it wanted the Windows giant to make custom, battle-ready AR headsets in a ten-year deal worth up to $22 billion. The project was delayed and is reportedly scheduled to roll out some time this year. But the US Dept of Defense's Office of the Inspector General (OIG) cast some doubt on whether it was worth it at all. "Procuring IVAS without attaining user acceptance could result in wasting up to $21.88 billion in taxpayer funds to field a system that soldiers may not want to use or use as intended," the Pentagon oversight body wrote in an audit [PDF] report this month. In other words, the Army hasn't yet fully determined if or how service members will find these HoloLens headsets valuable in the field. Although the heavily redacted report did not reveal soldiers' responses to the prototype testing, it said feedback from surveys showed "both positive and negative user acceptance." The Army plans to purchase 121,500 IVAS units from Microsoft while admitting that "if soldiers do not love IVAS and do not find it greatly enhances accomplishing the mission, then soldiers will not use it," the report disclosed.

PayPal is shuttering its San Francisco office as it evaluates its global office footprint. TechCrunch reports: Multiple sources say the payments giant is closing its San Francisco office on 425 Market St. which housed its Xoom business unit. PayPal acquired Xoom, which is focused on online money transfer technology and services, in 2015. A person familiar with internal happenings at the company said the employees that worked out of that office will work virtually with the ability to work from the company's headquarters office in San Jose. It is unclear how many employees are affected by the decision. An individual who commented on a post on the topic on the anonymous professional network, Blind, speculated that the reason behind the move could be San Francisco's Prop C, which levied a tax upon any San Francisco business that earns more than $50 million in gross receipts. Proceeds are to be directed toward housing and services in an attempt to address the city's challenges with homelessness.

An anonymous reader quotes a report from Ars Technica: Vulnerabilities recently discovered by Microsoft make it easy for people with a toehold on many Linux desktop systems to quickly gain root system rights -- the latest elevation of privileges flaw to come to light in the open source OS. [...] Nimbuspwn, as Microsoft has named the EoP threat, is two vulnerabilities that reside in the networkd-dispatcher, a component in many Linux distributions that dispatch network status changes and can run various scripts to respond to a new status. When a machine boots, networkd-dispatcher runs as root. [...] A hacker with minimal access to a vulnerable desktop can chain together exploits for these vulnerabilities that give full root access. [The step-by-step exploit flow can be found in the article. The researcher also was able to gain persistent root access using the exploit flow to create a backdoor.] The proof-of-concept exploit works only when it can use the "org.freedesktop.network1" bus name. The researcher found several environments where this happens, including Linux Mint, in which the systemd-networkd by default doesn't own the org.freedodesktop.network1 bus name at boot. The researcher also found several processes that run as the systemd-network user, which is permitted to use the bus name required to run arbitrary code from world-writable locations. The vulnerable processes include several gpgv plugins, which are launched when apt-get installs or upgrades, and the Erlang Port Mapper Daemon, which allows running arbitrary code under some scenarios. The vulnerability has been patched, although it's unclear which version of Linux the patch is in.

Major technology companies have been duped into providing sensitive personal information about their customers in response to fraudulent legal requests, and the data has been used to harass and even sexually extort minors, according to four federal law enforcement officials and two industry investigators. Bloomberg: The companies that have complied with the bogus requests include Meta, Apple, Alphabet's Google, Snap, Twitter and Discord, according to three of the people. All of the people requested anonymity to speak frankly about the devious new brand of online crime that involves underage victims. The fraudulently obtained data has been used to target specific women and minors, and in some cases to pressure them into creating and sharing sexually explicit material and to retaliate against them if they refuse, according to the six people. The tactic is considered by law enforcement and other investigators to be the newest criminal tool to obtain personally identifiable information that can be used not only for financial gain but to extort and harass innocent victims. It is particularly unsettling since the attackers are successfully impersonating law enforcement officers. The tactic is impossible for victims to protect against, as the best way to avoid it would be to not have an account on the targeted service, according to the people. It's not clear how often the fraudulent data requests have been used to sexually extort minors. Law enforcement and the technology companies are still trying to assess the scope of the problem.

Cryptocurrency companies said they remain unsure of U.S. regulations governing products that allow customers to earn interest on holdings instead of trading them, months after such an interest-bearing product drew a $100 million fine from a federal regulator and state governments. From a report: In February, New Jersey crypto company BlockFi agreed to pay $100 million in a landmark settlement with the U.S. Securities and Exchange Commission and state authorities who said its interest-bearing product qualifies as a security and should have been registered. Still, many digital asset companies providing such products said this month the rules remain unclear to them and they are uncertain when they should register such offerings, which are growing more popular and which many firms launched within the last year. Most firms have tried to structure the interest-bearing products to avoid the need to register them with the SEC, a process that takes time and entails ongoing disclosure and reporting obligations. That effort might set them up for a clash with the agency as it increases scrutiny of the crypto industry. BlockFi plans to offer an alternative yield product, which it said it would register first. The company and the SEC said the deal should provide a roadmap for other companies.

Fibre-optic cable is being laid across the globe at great expense to speed up people's internet connections, but researchers claim that the copper telephone wire already in use across the country can achieve data rates three times higher than currently seen at a fraction of the price, at least over short distances. New Scientist: Their technique to boost speeds may help to ease the transition to nationwide fibre optic, and may also be of use in countries that use similar twisted-pair copper wire. Ergin Dinc at the University of Cambridge and his colleagues say that twisted pairs of copper wire, of the type used for decades as telephone lines and now repurposed for broadband internet, can support a frequency fives times higher than is currently used, which would dramatically improve data transmission rates. Above that limit, the researchers found that the wire essentially acts as an aerial and transforms any signal sent along it into radio waves that dissipate before reaching their destination. "These cables are actually very old, invented by Alexander Graham Bell, and since then no one has looked into the theoretical limits," says Dinc. He and his colleagues say that their findings may allow houses near fibre-optic cables to achieve higher speeds than they currently enjoy without the expense of running fibre all the way to their home. Fibre-optic cables carry groups of photons to represent data, and huge numbers of these groups can be sent along the line one after another without waiting for the first to arrive. Fibre connections in use today typically operate at 1 gigabit per second, but theoretical speeds could be many thousands of times higher.

At least six different Kremlin-linked hacking groups have conducted nearly 240 cyber operations against Ukrainian targets, Microsoft said Wednesday, in data reveal a broader scope of alleged Russian cyberattacks during the war on Ukraine than previously documented. From a report: "Russia's use of cyberattacks appears to be strongly correlated and sometimes directly timed with its kinetic military operations," said Tom Burt, a Microsoft vice president. The Microsoft report is the most comprehensive public record yet of Russian hacking efforts related to the war in Ukraine. It fills in some gaps in public understanding of where Russia's vaunted cyber capabilities have been deployed during the war. Burt cited a cyberattack on a Ukrainian broadcast company on March 1, the same day as a Russian missile strike against a TV tower in Kyiv, and malicious emails sent to Ukrainians falsely claiming the Ukrainian government was "abandoning" them amid the Russian siege of the city of Mariupol. Suspected Russian hackers "are working to compromise organizations in regions across Ukraine," and may have been collecting intelligence on Ukrainian military partnerships many months before the full-scale invasion in February, the Microsoft report says.

This week at the 2022 NAB Show Streaming Summit, Google launched in general availability Media CDN, a platform for delivering content using the same infrastructure that powers YouTube. From a report: With a presence in over 1,300 cities across 200 countries, Google says that Media CDN is designed to -- in the company's words -- "automate all facets" of "serving content [close to users]." The pandemic led to an explosion in demand for streaming content as business closures and shelter-in-place orders forced folks to stay home. Media CDN, which joins Google's CDN portfolio for web and API acceleration, is by no stretch of the imagination the first of its kind. There's plenty of CDNs optimized to serve media. But Google touts ostensibly unique benefits like delivery protocols tailored to individual users and network conditions and "industry-leading" offload rates. "With multiple tiers of caching, we minimize calls to origin -- even for infrequently accessed content," Google VP Shailesh Shukla wrote in a blog post yesterday. "This alleviates performance or capacity stress in the content origin and saves costs." Media CDN also features tools for ad insertion, allowing customers to dynamically inject video content with ads. Moreover, the service is "built with AI/ML" to power interactive experiences, Google says, like real-time stats during sporting events and purchase links embedded in virtual billboards.

As the old saying goes, if you can't beat 'em, partner up with another overly powerful cable giant to give yourself a better shot. From a report: This morning, Comcast and Charter announced a new joint venture that will see the two companies teaming up to develop "a next-generation streaming platform on a variety of branded 4K streaming devices and smart TVs." This new platform and the devices that run it will square off against Amazon, Roku, Google, Apple, and other established streaming hardware players. The new venture is evenly divided between the two companies and is exclusively focused on streaming; it "does not involve the broadband or cable video businesses of either Comcast or Charter, which will remain independent." Comcast says its Flex streaming platform will serve as the foundation for what's coming next. It's also contributing "the retail business for XClass TVs and will contribute Xumo, a streaming service it acquired in 2020." Comcast introduced its XClass TVs last year as an alternative to the many popular budget TVs that come preloaded with Roku, Amazon, or Google software. For its part, Charter -- known better to many for its Spectrum brand -- is kicking in $900 million over the course of several years.

Arm has moved to regain control of its renegade China unit and replace its chief executive Allen Wu, as the UK chip designer seeks to clear its path to a successful public listing. From a report: The UK chip designer will put forward two individuals to act as co-chief executives of its China joint venture and has received official sign-off to submit the paperwork, according to two people with direct knowledge of the matter. The proposed candidates to take over as co-CEOs are Dr Liu Renchen, a government adviser and vice-dean of the Research Institute of Tsinghua University in Shenzhen and Vision Fund managing partner Eric Chen, who has been leading SoftBank's negotiations with Chinese officials. Arm has been trying to oust Wu for almost two years, afterâhe disregarded a 7 to 1 board vote for his removal and unilaterally took control of the company. "Discussions have been going on for a while and this is the proposed solution," said one person close to Arm China's board. "But submission is not the problem, getting authorities to sign off on it is," the person said. The person noted that previous deals to resolve the stand-off had fallen through at the last minute and cautioned: "We still have to see if Allen will be able to derail it."

Twitch, the Amazon-owned live-streaming website, is weighing potential changes to how it pays top talent, Bloomberg reported Wednesday, citing people familiar with the planning, an effort that would boost its profits but would also risk alienating some of its biggest stars. From a report: The updates under consideration would offer incentives for streamers to run more ads. The proposal would also reduce the proportion of subscription fees doled out to the site's biggest performers, said the people, who asked not to be identified because the discussions are private. Some changes to Twitch's monetization structure could be implemented as soon as this summer, the people said. Twitch staff is considering paring back the revenue cut of channel subscriptions granted to the top echelon of streamers in its so-called partnerships program to 50%, from 70%. Another option is to create multiple tiers and set criteria for how to qualify for each one, two of the people said. In exchange, Twitch may offer to release partners from exclusivity restrictions, allowing them to stream on Google's YouTube or Facebook.

Retail brokerage firm Robinhood is cutting back staffing levels, citing "duplicate roles and job functions" after rapid expansion last year. From a report: CEO Vlad Tenev made the announcement in a blog post on Tuesday afternoon. Shares fell more than 5% in extended trading. The move will affect about 9% of full-time employees. Robinhood reported 3,800 full-time employees as of Dec. 31. The company declined to give more detail on the exact number of employees being let go. "We determined that making these reductions to Robinhood's staff is the right decision to improve efficiency, increase our velocity, and ensure that we are responsive to the changing needs of our customers," Tenev wrote. "While the decision to undertake this action wasn't easy, it is a deliberate step to ensure we are able to continue delivering on our strategic goals and furthering our mission to democratize finance," he added.

When Sony's expanded PlayStation Plus service starts rolling out next month, it will fold in PlayStation Now, which offers access to hundreds of games from older console generations. Now, it seems the company is getting even more serious about game preservation. From a report: According to Twitter and LinkedIn posts spotted by Video Games Chronicle, Sony has hired at least one engineer (Garrett Fredley, a former build engineer for mobile developer Kabam) to work on a new preservation team. "Today is my first day as a Senior Build Engineer at @PlayStation, working as one of their initial hires for the newly created Preservation team! Game Preservation was my first career passion, so I'm ecstatic that I get to go back to those roots," Fredley wrote. "Let's go and ensure our industry's history isn't forgotten!" [...] Sony historically hasn't done an incredible job with preserving games. Aside from the original PS3 models being able to run many PS1 and PS2 games, backward compatibility seemed like an afterthought until the PS5, which supports all but a few PS4 titles.
