Apple and Amazon Release Warm, Fuzzy Holiday Ads - Both With Beatles-Related Songs (youtube.com) 23

Long-time Slashdot reader theodp writes: For the soundtracks to their 2023 holiday season ads, both Amazon and Apple turned to music by members of The Beatles. Amazon's Joy Ride, which stars three older women reliving their youthful joy at a sledding hill, is set to a cover of The Beatles' In My Life. Apple's Fuzzy Feelings, which tells the story of a young woman with a grumpy boss, is set to George Harrison's Isn't It a Pity.

Product placement is present in both ads — Amazon features padded seat cushions that protect the seniors' tushes and the Amazon app used to order them, while Apple showcases the iPhone 15 Pro Max used to capture the ad's stop-motion animation scenes and the MacBook Air used to edit them.

Amazon's 60-second ad has 542K views on YouTube, while Apple's 4-minute ad has 16+ million views.

Firefox's Android Browser Adds 450+ New Extensions (techcrunch.com) 22

Firefox's Android browser now has over 450 new extensions available on Mozilla's Firefox Browser Add-ons page. "These extensions allow users to customize the mobile browser to their needs, whether that involves adding anti-tracking privacy tools, content blockers, productivity tools or other features that introduce new experiences, like streaming music, or those that allow users to personalize the browser's user interface -- like switching all websites to a dark mode or offering a better way to manage tabs," reports TechCrunch. From the report: The lack of extensions has been an issue for Firefox for Android users for years following the 2020 launch of a rebuilt version of the mobile browser that replaced the app's previous codebase with "GeckoView," a new, faster and more customizable browser engine. At the time, the company said it made a decision to limit the supported extensions to only those within the "Recommended Extensions" program -- meaning those that were commonly installed by end users. This choice allowed Mozilla to quickly get the new browser into consumers' hands, but squashed the long tail of extension development -- and opportunity for software developers focused on this market.

While Firefox's nightly builds later enabled more extensions, the publicly available Firefox for Android browser did not have access to these hundreds of extensions, meaning most of Firefox's mainstream users were also without. In August of this year, Mozilla said it had finally completed the infrastructure needed to bring the open extension ecosystem back to Firefox for Android. It then began to test and make hundreds more extensions available to Firefox for Android users, culminating in today's news that there are now 450+ extensions available.

The Excitement of 70,000 Swifties Can Shake the Earth (economist.com) 46

The Economist reports: "Shake, shake, shake, shake," Taylor Swift sings from the stage of Lumen Field in Seattle at 10.35 in the evening on July 22nd. The fans respond, enthusiastically; the stadium duly shakes; a nearby seismometer takes note. To pop aficionados "Shake it off" is an empowering up-tempo anthem played at 160 beats per minute. To the Pacific Northwest Seismic Network, which is designed to monitor earthquakes, it is a 2.6 hertz signal in which the amplitude of the acceleration was as large as one centimetre per second, per second.

The well-situated seismometer first came to public attention in January 2011, when it recorded the response of fans of the Seattle Seahawks, an American football team, to a magnificent touchdown by Marshawn Lynch, a running back known as "Beast Mode." The "Beast Quake" went down in local sporting history. When Ms Swift came to town for two nights of her Eras tour, Jacqueline Caplan-Auerbach, a geology professor at Western Washington University, used the opportunity to learn more about how events in the stadium shake its surroundings. On December 11th she presented some of her conclusions at the American Geophysical Union's autumn meeting in San Francisco.

[...] Dr Caplan-Auerbach wanted to see whether such resonant amplification might also be at play elsewhere, and to distinguish between the effect of the music itself and the audience's response. Her concert-night data showed two distinct sets of signals, one in higher frequencies (30-80hz), one in lower frequencies (1-8hz). The higher-frequency signals were present during the sound check, when the band were on stage but the stadium empty, and absent during the concerts' "surprise songs," played without the band by Ms Swift alone. The lower frequencies were absent when the audience had yet to arrive. Clearly those higher frequencies were from the music itself.

Are Tiny Black Holes Hiding Within Giant Stars? (science.org) 43

sciencehabit shares a report from Science Magazine: Grunge music: a source of validation for a generation of disaffected youth. And a surprising source of scientific inspiration for Earl Bellinger of the Max Planck Institute for Astrophysics. While listening to Soundgarden's 1994 hit Black Hole Sun 2 years ago, he contemplated a curious question: Might itty-bitty black holes from the dawn of time be lurking in the hearts of giant stars? A new study by Bellinger and colleagues suggests the idea is not so far-fetched. Astronomers could detect these trapped black holes by the vibrations they cause on the star's surface. And if there's enough of them out there, they could function as the mysterious dark matter that holds the universe together.

The researchers found that the black holes would sink to the star's core where hydrogen atoms undergo fusion to produce heat and light. At first, very little would happen. Even a dense stellar core is mostly empty space. The most microscopic of the black holes would have a hard time finding matter to consume and its growth would be extremely slow, Bellinger says. "It could take longer than the lifetime of the universe to eat the star." But larger ones, roughly as massive as the asteroid Ceres or the dwarf planet Pluto, would get bigger on timescales of only a few hundred million years. Material would spiral onto the black hole, forming a disk that would heat up through friction and emit radiation. Once the black hole was about as massive as Earth, it would produce significant amounts of radiation, shining brightly and churning up the star's core like pot of boiling water. "It will become a black hole -- powered object rather than fusion-powered object," says study co-author Matt Caplan, a theoretical physicist at Illinois State University. He and his colleagues have dubbed these entities "Hawking stars."

The European Space Agency's Gaia satellite has spotted about 500 such anomalously cool giant stars, known as red stragglers, Bellinger says. To figure out whether these might actually be hiding a black hole, he says, astronomers could tune in to the particular frequencies at which the stars vibrate. Because a Hawking star would churn throughout its interior, rather than just in the topmost layers like an ordinary red giant, it would be expected to thrum with a particular combination of frequencies. Such waves can be detected in the way the star's light pulses and throbs. Bellinger is applying for funding to study the known red stragglers and see whether any display the characteristic vibrations of a black hole.
The study has been published in The Astrophysical Journal.

Apple Set to Be Hit by EU Antitrust Order in App Store Fight With Spotify (bloomberg.com) 13

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

Android Vulnerability Exposes Credentials From Mobile Password Managers (techcrunch.com) 22

An anonymous reader quotes a report from TechCrunch: A number of popular mobile password managers are inadvertently spilling user credentials due to a vulnerability in the autofill functionality of Android apps. The vulnerability, dubbed "AutoSpill," can expose users' saved credentials from mobile password managers by circumventing Android's secure autofill mechanism, according to university researchers at the IIIT Hyderabad, who discovered the vulnerability and presented their research at Black Hat Europe this week. The researchers, Ankit Gangwal, Shubham Singh and Abhijeet Srivastava, found that when an Android app loads a login page in WebView, password managers can get "disoriented" about where they should target the user's login information and instead expose their credentials to the underlying app's native fields, they said. This is because WebView, the preinstalled engine from Google, lets developers display web content in-app without launching a web browser, and an autofill request is generated.

"Let's say you are trying to log into your favorite music app on your mobile device, and you use the option of 'login via Google or Facebook.' The music app will open a Google or Facebook login page inside itself via the WebView," Gangwal explained to TechCrunch prior to their Black Hat presentation on Wednesday. "When the password manager is invoked to autofill the credentials, ideally, it should autofill only into the Google or Facebook page that has been loaded. But we found that the autofill operation could accidentally expose the credentials to the base app." Gangwal notes that the ramifications of this vulnerability, particularly in a scenario where the base app is malicious, are significant. He added: "Even without phishing, any malicious app that asks you to log in via another site, like Google or Facebook, can automatically access sensitive information."

The researchers tested the AutoSpill vulnerability using some of the most popular password managers, including 1Password, LastPass, Keeper and Enpass, on new and up-to-date Android devices. They found that most apps were vulnerable to credential leakage, even with JavaScript injection disabled. When JavaScript injection was enabled, all the password managers were susceptible to their AutoSpill vulnerability. Gangwal says he alerted Google and the affected password managers to the flaw. Gangwal tells TechCrunch that the researchers are now exploring the possibility of an attacker potentially extracting credentials from the app to WebView. The team is also investigating whether the vulnerability can be replicated on iOS.

Spotify Cuts 17% Jobs Amid Rising Capital Costs (techcrunch.com) 45

Spotify is eliminating about 1,500 jobs, or about 17% of its workforce, in its third round of layoffs this year as the music streaming giant looks to become "both productive and efficient." From a report: In a note to employees Monday, Spotify founder and chief executive Daniel Ek said right-sizing the workforce is crucial for the company to face the "challenges ahead." He cited the slow economic growth and rising capital costs among reasons for the job cuts, saying the firm took advantage of lower-cost capital in 2020 and 2021 to invest significantly in the business. "I recognize this will impact a number of individuals who have made valuable contributions. To be blunt, many smart, talented and hard-working people will be departing us," he wrote in the note, which the company later published on the blog.

After KISS's Final Show, They'll Become Digital Avatars From Industrial Light & Magic (go.com) 93

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

Digital avatars of the band followed, playing their anthem, "God Gave Rock and Roll To You."

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

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

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

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

Amazon Finally Releases Its Own AI-Powered Image Generator (techcrunch.com) 16

During a keynote at its re:Invent conference today, Amazon debuted the Titan Image Generator, which can create new images or customize existing images via a text description. It's now available in preview for AWS customers on Bedrock, Amazon's AI development platform. TechCrunch reports: Amazon says that Titan Image Generator was trained on a "diverse set of datasets" across a "broad range of domains" and can be optionally fine-tuned on custom datasets, and includes built-in mitigations for toxicity and bias. (Barring testing, the jury's out on just how effective those mitigations are, of course.) The company declined to say exactly where those datasets came from however -- and whether it obtained permission from or is compensating all the creators of the images used to train Titan Image Generator. [...] Sivasubramanian did claim onstage, however, that Amazon will protect customers accused of violating copyright with images generated by Titan Image Generator -- in keeping with its AI indemnification policy. That's surely music to the ears of AWS customers worried about regurgitation, or when a generative model spits out a mirror copy of a training example.

Images created with Titan Image Generator will also come with a "tamper-resistant" invisible watermark by default -- an attempt to mitigate the spread of AI-generated misinformation and abuse imagery, Sivasubramanian says. (Deepfakes from the Gaza war and AI-generated child abuse images are the latest illustrations of how major the threat's become.) It's not clear exactly what sort of watermarking technique Amazon's using and which tools beyond Amazon's own API will be able to detect it; we've reached out to Amazon for clarification. Sivasubramanian noted watermarks are a part of the voluntary commitment around AI that Amazon signed with the White House in July.

Tech's New Normal: Microcuts Over Growth at All Costs (wsj.com) 78

The tech industry has largely recovered from the downturn, but Silicon Valley learned a long-lasting lesson: how to do more with less. From a report: Amazon, Google, Microsoft and Meta Platforms have been cutting dozens or a few hundred employees at a time as executives keep tight controls on costs, even as their businesses and stock prices have rebounded sharply. The cuts are far smaller than the mass layoffs that reached tens of thousands in late 2022 and early this year. But they suggest a new era for an industry that in years past grew with little restraint, one in which companies are focusing on efficiency and acting more like their corporate peers that emphasize shareholder value and healthy margins.

The launch of the humanlike chatbot ChatGPT late last year served as a bright spot of growth in an industry that was otherwise scaling back. Challenges regarding the technology and calls for regulation remain, but some of the biggest tech companies are starting to make it their priority. There is a reallocation of resources from noncore areas to projects such as AI rather than hiring new people, said Ward, who was previously a director of recruiting at Facebook and the head of recruiting at Pinterest.

Amazon eliminated several hundred roles this month from its Alexa division to maximize its "resources and efforts focused on generative AI," according to an internal memo. The company has also made small cuts in recent weeks to its gaming and music divisions. Facebook's parent, Meta, recently posted its largest quarterly revenue in more than a decade. It laid off 20 people weeks later. Chief Executive Officer Mark Zuckerberg said on an earnings call that the company would continue to operate more efficiently going forward "both because it creates a more disciplined and lean culture, and also because it provides stability to see our long-term initiatives through in a very volatile world."

Spotify To Phase Out Service In Uruguay Following New Copyright Bill (theguardian.com) 36

Laura Snapes reports via The Guardian: Spotify is to phase out its service in Uruguay after the passing of a new music copyright bill requiring "fair and equitable remuneration" for authors, composers, performers, directors and screenwriters. In October, the country's parliament voted on a budget bill that included two new articles: per article 284, social networks and the internet are to be added "as formats for which, if a song is reproduced, the performer is entitled to financial remuneration" -- namely if a link to a song is shared online. Article 285 will put into copyright law the "right to a fair and equitable remuneration" for all "agreements entered into by authors, composers, performers, directors and screenwriters with respect to their faculty of public communication and making available to the public of phonograms and audiovisual recordings."

In response, Spotify said in a statement on November 20 that without changes to the 2023 Rendicion de Cuentas law, the streaming platform "will, unfortunately, begin to phase out its service in Uruguay effective January 1, 2024" and cease trading in the market in February 2024. The Swedish company seeks confirmation on whether additional costs to be paid to musicians are the responsibility of rights holders or the streaming platforms, arguing that the latter means that it would be required "to pay twice for the same music," Music Business Worldwide reports. The statement continued: "Spotify already pays nearly 70% of every dollar it generates from music to the record labels and publishers that own the rights for music, and represent and pay artists and songwriters. Any additional payments would make our business untenable." The platform claimed that it had contributed to a 20% growth in Uruguay's music industry in 2022. That year, the South American nation was the 53rd largest market for music.

A Secret Google Deal Let Spotify Completely Bypass Android's App Store Fees (theverge.com) 22

An anonymous reader quotes a report from The Verge: Music streaming service Spotify struck a seemingly unique and highly generous deal with Google for Android-based payments, according to new testimony in the Epic v. Google trial. On the stand, Google head of global partnerships Don Harrison confirmed Spotify paid a 0 percent commission when users chose to buy subscriptions through Spotify's own system. If the users picked Google as their payment processor, Spotify handed over 4 percent -- dramatically less than Google's more common 15 percent fee. Google fought to keep the Spotify numbers private during its antitrust fight with Epic, saying they could damage negotiations with other app developers who might want more generous rates.

Google's User Choice Billing program, launched in 2022, is typically described as shaving about 4 percent off Google's Play Store commission if developers use their own payment system, bringing down Google's 15 percent subscription service fee to more like 11 percent. That often ends up saving developers little or no money since they must foot the cost of payment processing themselves. And in court, Google has focused on benefits like greater flexibility rather than cost savings. [...] Harrison says Spotify's "unprecedented" popularity was great enough to justify a "bespoke" deal. "If we don't have Spotify working properly across Play services and core services, people will not buy Android phones," Harrison testified. As part of the deal, both parties also agreed to commit $50 million apiece to a "success fund."

Google acknowledged Harrison's testimony in a statement to The Verge. "A small number of developers that invest more directly in Android and Play may have different service fees as part of a broader partnership that includes substantial financial investments and product integrations across different form factors," says spokesperson Dan Jackson. "These key investment partnerships allow us to bring more users to Android and Play by continuously improving the experience for all users and create new opportunities for all developers." Google would not name other developers that have gotten the company to agree to more generous rates. During the trial, we learned that Google offered Netflix a special discounted rate of just 10 percent, but Netflix refused. Netflix no longer offers an in-app purchase option on Android and no longer pays Google anything to distribute its app as a result.

Sonos Teases Plans To Enter Headphones Product Category (macrumors.com) 25

Sonos announced plans to expand into a new "multi-billion dollar" product category next year. Sonos CEO Patrick Spence declined to give specific details, but it's widely expected to be headphones. He said the new product will "complement" current Sonos devices and will "delight customers and drive immediate revenue." MacRumors reports: Spence said that Sonos believes it will generate more than $100 million from new products in 2024, and the new product will account for a "large portion" of this revenue in the second half of the year. There have been rumors for years now that Sonos intends to enter the headphone market with a pair of wireless headphones that could be similar in design to over-ear headphones like the AirPods Max.

Sonos has never confirmed its work on headphones, but a leaked internal memo that was obtained by Bloomberg earlier today confirmed that the company does indeed have a headphone division. [...] Bloomberg in 2019 said that Sonos was targeting a $300 price point and was focusing on features like audio quality and multi-service interoperability, but it has been several years since new details emerged.

MediaTek Partners With Meta To Develop Chips For AR Smart Glasses (9to5google.com) 7

During MediaTek's 2023 summit, MediaTek executive Vince Hu announced a new partnership with Meta that would allow it to develop smart glasses capable of augmented reality or mixed reality experiences. 9to5Google reports: As the current generation exists, the Ray-Ban Meta glasses feature a camera and microphone for sending and receiving messages. However, the next generation of Meta smart glasses are likely to have a built-in "viewfinder" display to merge the virtual and physical worlds, allowing users to scan QR codes, read messages, and more. Beyond that, the company wants to bring AR glasses into the fold, which presents a much broader set of challenges. To accomplish this, a few things need to change. AR glasses need to be built for everyday use and optimized to take on an industrial design that looks good but can pack enough tech to ensure a good experience. As it stands, mixed-reality headsets are bulky and take on a large profile. Ideally, Meta's fully AR glasses would be thinner and sleeker.

The new partnership between companies means that MediaTek will help co-develop custom silicon with Meta, built specifically for AR use cases and the glasses. MediaTek brings expertise in developing low-power, high-performance SoCs that can fit within small parameters, like in the frame in a pair of AR glasses. Little to no details were revealed about the upcoming AR glasses, other than directly stating that "MediaTek-powered AR glasses from Meta" would be a thing sometime in the future. Previous leaks position the next generation of smart glasses with a viewfinder as a 2025 release, while a more robust set of AR glasses was referred to as a 2027 product -- if done properly, it would be an incredible product.

YouTube Adapts Its Policies For the Coming Surge of AI Videos (techcrunch.com) 20

Sarah Perez reports via TechCrunch: YouTube today announced how it will approach handling AI-created content on its platform with a range of new policies surrounding responsible disclosure as well as new tools for requesting the removal of deepfakes, among other things. The company says that, although it already has policies that prohibit manipulated media, AI necessitated the creation of new policies because of its potential to mislead viewers if they don't know the video has been "altered or synthetically created." One of the changes that will roll out involves the creation of new disclosure requirements for YouTube creators. Now, they'll have to disclose when they've created altered or synthetic content that appears realistic, including videos made with AI tools. For instance, this disclosure would be used if a creator uploads a video that appears to depict a real-world event that never happened, or shows someone saying something they never said or doing something they never did.

It's worth pointing out that this disclosure is limited to content that "appears realistic," and is not a blanket disclosure requirement on all synthetic video made via AI. "We want viewers to have context when they're viewing realistic content, including when AI tools or other synthetic alterations have been used to generate it," YouTube spokesperson Jack Malon told TechCrunch. "This is especially important when content discusses sensitive topics, like elections or ongoing conflicts," he noted. [...] The company also warns that creators who don't properly disclose their use of AI consistently will be subject to "content removal, suspension from the YouTube Partner Program, or other penalties." YouTube says it will work with creators to make sure they understand the requirements before they go live. But it notes that some AI content, even if labeled, may be removed if it's used to show "realistic violence" if the goal is to shock or disgust viewers. [...]

Other changes include the ability for any YouTube user to request the removal of AI-generated or other synthetic or altered content that simulates an identifiable individual -- aka a deepfake -- including their face or voice. But, the company clarifies that not all flagged content will be removed, making room for parody or satire. It also says that it will consider whether or not the person requesting the removal can be uniquely identified or whether the video features a public official or other well-known individual, in which case "there may be a higher bar," YouTube says. Alongside the deepfake request removal tool, the company is introducing a new ability that will allow music partners to request the removal of AI-generated music that mimics an artist's singing or rapping voice.

The $2,000 Phones That Let Anyone Make Robocalls (404media.co) 24

An anonymous reader writes: Videos collected by 404 Media over months give a peek into the world of spoofing numbers, automated call scripts, and a specific seller of the phones. From the report: "Alright lads," a man sitting in the passenger seat of a moving car says in a heavy British accent. In his left hand he holds a special phone he is showing off to his clients, while with the other he films his demonstration which was later uploaded to Telegram. "I'm only going to say it once, yeah. You swipe, and it's gone," he continues, demonstrating one app installed that can instantly destroy data stored on the device. The phone in question is one from "Russiancoms," an underground outfit that sells the devices for just under $2,000 each. For that price, customers get a laundry list of features: the ability to spoof phone numbers, play hold music, and have a computerized voice read pre-determined scripts. While Russiancoms does not acknowledge in its Telegram channel what the phones might really be for, those are features well suited to committing fraud.

The Russiancoms Telegram channel periodically deletes its videos and other messages, but 404 Media has been archiving many of them for months. They provide insight into a little known industry of fraud phones, ones that make it easy for anyone to enter the world of robocalling or other scams. While much of the underground phone industry has been focused on providing secure communications to criminals -- companies like Phantom Secure, Encrochat, and Sky for example -- Russiancoms and similar companies appear to cater to a different use case: enabling people to make calls that fraudulently appear to come from someone else. A common tool in the underground is also so-called Russian SIMs, which can spoof numbers in some cases. Russiancoms' phones, however, are more fully featured.

Google Can Turn ANC Earbuds Into a Heart Rate Monitor With No Extra Hardware (9to5google.com) 20

Abner Li reports via 9to5Google: Google today detailed its research into audioplethysmography (APG) that adds heart rate sensing capabilities to active noise canceling (ANC) headphones and earbuds "with a simple software upgrade." Google says the "ear canal [is] an ideal location for health sensing" given that the deep ear artery "forms an intricate network of smaller vessels that extensively permeate the auditory canal."

This audioplethysmography approach works by "sending a low intensity ultrasound probing signal through an ANC headphone's speakers. This signal triggers echoes, which are received via on-board feedback microphones. We observe that the tiny ear canal skin displacement and heartbeat vibrations modulate these ultrasound echoes." A model that Google created works to process that feedback into a heart rate reading, as well as heart rate variability (HRV) measurement. This technique works even with music playing and "bad earbuds seals." However, it was impacted by body motion, and Google countered with a multi-tone approach that serves as a calibration tool to "find the best frequency that measures heart rate, and use only the best frequency to get high-quality pulse waveform."

Google performed two sets of studies with 153 people that found APG "achieves consistently accurate heart rate (3.21% median error across participants in all activity scenarios) and heart rate variability (2.70% median error in inter-beat interval) measurements." Compared to existing HR sensors, it's not impacted by skin tones. Ear canal size and "sub-optimal seal conditions" also do not impact accuracy. Google believes this is a better approach than putting traditional photoplethysmograms (PPG) and electrocardiograms (ECG) sensors, as well as a microcontroller, in headphones/earbuds: "this sensor mounting paradigm inevitably adds cost, weight, power consumption, acoustic design complexity, and form factor challenges to hearables, constituting a strong barrier to its wide adoption."

Record Labels Shut Down FileWarez, Brazil's Oldest Pirate Forum (torrentfreak.com) 12

An anonymous reader quotes a report from TorrentFreak: As far as we know, Brazil-based file-sharing forum FileWarez.com first appeared in August 2004, its domain name having been registered the previous month. The default language was naturally Portuguese and according to this image from the Wayback Machine, potential members needed a basic grip of the language to sign up. After all, Google Translate wouldn't exist for another two years. At some point in the years that followed, FileWarez shifted to a Netherlands .NL domain supported by filewarez.no-ip.biz, which may suggest a site regularly on the move. In 2008, unspecified problems saw the .NL domain dumped in favor of a new one. Riding out problems, various issues, and bouts of downtime, FileWarez.tv stayed in place for the next 15.5 years. Then two weeks ago, after establishing itself as Brazil's oldest file-sharing forum, FileWarez suddenly vanished.

In a press release Wednesday, global music industry group IFPI announced that "prominent illegal file-sharing forum, FileWarez," was shut down following co-ordinated action by record companies, anti-piracy body APDIF, and local cybercrime unit, Cyber Gaeco. "IFPI, the organization that represents the recorded music industry worldwide, alongside its Brazilian national group Pro-Musica, have welcomed the successful action against FileWarez.tv -- one of the most prominent illegal file sharing sites in Brazil -- by the Brazilian special cybercrime unit of prosecutor's office of Sao Paulo, Cyber Gaeco," the announcement reads. "FileWarez was the most established illegal filesharing forum in Brazil, dedicated to sharing illegal music content. While active, the site had more than 118,000 registered users with at least 24,000 monthly active users."

The Apple Watch's Double Tap Gesture Points At a New Way To Use Wearables (theverge.com) 44

Apple has introduced a completely new way to interact with the Apple Watch without ever needing to use the touchscreen. It's called Double Tap and it arrives today via the watchOS 10.1 update. The Verge reports: With a quick pinching motion, you can use it to scroll through the new smart stack of widgets in watchOS 10, pause or end timers, skip music tracks, and answer phone calls. It's the sort of feature that you might read about and scoff at -- until you're unloading groceries from your car, hands full, and an important call comes through on your watch. [...] Double tap technically isn't a new gesture so much. In 2021, Apple introduced Assistive Touch, an accessibility feature designed for people with limb differences or mobility issues. The idea was to give these folks a way to navigate through menus and control the Apple Watch without needing a second hand.

On the surface, it can seem like double tap is a rebadged version of Assistive Touch. That's led to understandable confusion as to how the two features differ -- and why double tap isn't available on older Apple Watches that support Assistive Touch (Series 4 or later, including the first-gen SE and Ultra). The short answer is that the Apple Watch Series 9 and Ultra 2 have a more powerful chip. Specifically, the new S9 features four neural engines for machine learning, which is what powers double tap. On older watches, Assistive Touch was run on the main CPU.

But practically speaking, it's easier to see how Assistive Touch and double tap differ once you try using both. [...] Double tap isn't designed to help you navigate anything. The best way I can describe it is Assistive Touch is like the mouse to your computer. It scrolls, it selects, and it's highly programmable. Double tap is more like the double-click portion of using a mouse. You use it solely to perform the main action of an app. And to do that, Apple had to spend a lot of time researching what people wanted or expected a single double tap to do.
