Soundslice Adds ASCII Tab Support After ChatGPT Hallucinates Feature

Thu, 2025-07-10 02:45
After discovering that ChatGPT was falsely telling users that Soundslice could convert ASCII tablature into playable music, founder Adrian Holovaty decided to actually build the feature -- even though the app was never designed to support that format. TechCrunch reports: Soundslice is an app for teaching music, used by students and teachers. It's known for its video player synchronized to the music notations that guide users on how the notes should be played. It also offers a feature called "sheet music scanner" that allows users to upload an image of paper sheet music and, using AI, will automatically turn that into an interactive sheet, complete with notations. [Adrian Holovaty, founder of music-teaching platform Soundslice] carefully watches this feature's error logs to see what problems occur, where to add improvements, he said. That's where he started seeing the uploaded ChatGPT sessions. They were creating a bunch of error logs. Instead of images of sheet music, these were images of words and a box of symbols known as ASCII tablature. That's a basic text-based system used for guitar notations that uses a regular keyboard. (There's no treble key, for instance, on your standard QWERTY keyboard.) The volume of these ChatGPT session images was not so onerous that it was costing his company money to store them and crushing his app's bandwidth, Holovaty said. He was baffled, he wrote in a blog post about the situation. "Our scanning system wasn't intended to support this style of notation. Why, then, were we being bombarded with so many ASCII tab ChatGPT screenshots? I was mystified for weeks -- until I messed around with ChatGPT myself." That's how he saw ChatGPT telling people they could hear this music by opening a Soundslice account and uploading the image of the chat session. Only, they couldn't. Uploading those images wouldn't translate the ASCII tab into audio notes. He was struck with a new problem. "The main cost was reputational: New Soundslice users were going in with a false expectation. They'd been confidently told we would do something that we don't actually do," he described to TechCrunch. He and his team discussed their options: Slap disclaimers all over the site about it -- "No, we can't turn a ChatGPT session into hearable music" -- or build that feature into the scanner, even though he had never before considered supporting that offbeat musical notation system. He opted to build the feature. "My feelings on this are conflicted. I'm happy to add a tool that helps people. But I feel like our hand was forced in a weird way. Should we really be developing features in response to misinformation?" he wrote.

Hugging Face Launches $299 Robot That Could Disrupt Entire Robotics Industry

Thu, 2025-07-10 02:02
An anonymous reader quotes a report from VentureBeat: Hugging Face, the $4.5 billion artificial intelligence platform that has become the GitHub of machine learning, announced Tuesday the launch of Reachy Mini, a $299 desktop robot designed to bring AI-powered robotics to millions of developers worldwide. The 11-inch humanoid companion represents the company's boldest move yet to democratize robotics development and challenge the industry's traditional closed-source, high-cost model. The announcement comes as Hugging Face crosses a significant milestone of 10 million AI builders using its platform, with CEO Clement Delangue revealing in an exclusive interview that "more and more of them are building in relation to robotics." The compact robot, which can sit on any desk next to a laptop, addresses what Delangue calls a fundamental barrier in robotics development: accessibility. "One of the challenges with robotics is that you know you can't just build on your laptop. You need to have some sort of robotics partner to help in your building, and most people won't be able to buy $70,000 robots," Delangue explained, referring to traditional industrial robotics systems and even newer humanoid robots like Tesla's Optimus, which is expected to cost $20,000-$30,000. Reachy Mini emerges from Hugging Face's April acquisition of French robotics startup Pollen Robotics, marking the company's most significant hardware expansion since its founding. The robot represents the first consumer product to integrate natively with the Hugging Face Hub, allowing developers to access thousands of pre-built AI models and share robotics applications through the platform's "Spaces" feature. [...] Reachy Mini packs sophisticated capabilities into its compact form factor. The robot features six degrees of freedom in its moving head, full body rotation, animated antennas, a wide-angle camera, multiple microphones, and a 5-watt speaker. The wireless version includes a Raspberry Pi 5 computer and battery, making it fully autonomous. The robot ships as a DIY kit and can be programmed in Python, with JavaScript and Scratch support planned. Pre-installed demonstration applications include face and hand tracking, smart companion features, and dancing moves. Developers can create and share new applications through Hugging Face's Spaces platform, potentially creating what Delangue envisions as "thousands, tens of thousands, millions of apps." Reachy Mini's $299 price point could significantly transform robotics education and research. "Universities, coding bootcamps, and individual learners could use the platform to explore robotics concepts without requiring expensive laboratory equipment," reports VentureBeat. "The open-source nature enables educational institutions to modify hardware and software to suit specific curricula. Students could progress from basic programming exercises to sophisticated AI applications using the same platform, potentially accelerating robotics education and workforce development." "... For the first time, a major AI platform is betting that the future of robotics belongs not in corporate research labs, but in the hands of millions of individual developers armed with affordable, open-source tools."

IKEA Ditches Zigbee For Thread Going All In On Matter Smart Homes

Thu, 2025-07-10 01:20
IKEA is relaunching its smart home line with over 20 new Matter-over-Thread devices that will work across ecosystems such as Apple Home and Amazon Alexa, with or without IKEA's own hub. This marks a major shift toward openness, affordability, and interoperability, and positions IKEA as one of the first major retailers to bring Matter to the mainstream while maintaining backward compatibility with Zigbee products. The Verge reports: We don't have a lot of details on the over 20 new devices coming next year, but [David Granath of IKEA of Sweden] confirmed that they are replacing existing functions. So, new smart bulbs, plugs, sensors, remotes, buttons, and air-quality devices, including temperature and humidity monitors. They will also come with a new design. Although "not necessarily what's been leaked," says Granath, referring to images of the Bilresa Dual Button that appeared earlier this year. He did confirm that some new product categories will arrive in January, with more to follow in April and beyond, including potentially Matter-over-Wi-Fi products. Pricing will be comparable to or lower than that of previous products, which start under $10. "Affordability remains a key priority for us." "The premium to make a product smart is not that high anymore, so you can expect new product types and form factors coming," he says. "Matter unlocks interoperability, ease of use, and affordability for us. The standardization process means more companies are sharing the workload of developing for this." Despite the move away from Zigbee, IKEA is keeping Zigbee's Touchlink functionality. This point-to-point protocol allows devices to be paired directly to each other and work together out of the box, without an app or hub -- such as the bulb and remote bundles IKEA sells. This means older Zigbee remotes can control the newer Thread bulbs and vice versa, retaining backward compatibility with its Tradfri line. "Touchlink and Matter will coexist in new products," says Granath. "It's still very important for IKEA -- not everyone wants an app or hub." Interestingly, IKEA's new Matter-over-Thread products will also work without the IKEA hub or app, as they can be set up directly in any compatible Matter smart home ecosystem, such as Apple Home, Amazon Alexa, Google Home, Samsung SmartThings, Home Assistant, and others.

UK Full-Fiber Broadband Coverage Jumps From 12% to 78% in Five Years

Thu, 2025-07-10 00:40
The UK has transformed its broadband infrastructure in five years -- with full-fiber coverage jumping from 12% of properties in January 2020 to more than 78% by 2025, according to communications regulator Ofcom and ThinkBroadband data. Northern Ireland leads with 96% of premises in postcodes served with full-fiber connections. The rollout accelerated after Ofcom's May 2021 regulatory framework gave other providers access to BT's Openreach ducts and poles while promising the company regulatory certainty through a "fair bet" approach that avoided price caps. The framework sparked investment from alternative networks, or "altnets," which increased homes passed from 8.2 million in 2022 to 16.4 million by 2025.

Samsung Launches Three New Foldable Smartphones As It Fends Off Chinese Rivals

Thu, 2025-07-10 00:00
Samsung on Wednesday unveiled three new foldable smartphones at a time when the company is facing increased competition from Chinese rivals such as Honor and Oppo, reports CNBC. The company's share of the global foldable phone market slipped to 45% in 2024, down from 54% a year earlier. Today's new devices include the ultra-thin Galaxy Z Fold 7, the clamshell-style Galaxy Z Flip 7, and the more affordable Flip 7 FE. Here's a breakdown of each: The Galaxy Z Fold 7 is super thin at a thickness of 8.9 millimeters (0.35 inches) closed and only 4.2 millimeters open. It's also much lighter than its predecessor, weighing 215 grams (7.62 ounces). These stats put the phone on par with both Honor's Magic V5 and the Oppo Find N5. The new Fold device has a 6.5-inch cover screen and an 8-inch main display when opened, making it bigger than its predecessor. It's also decked out with premium new cameras, featuring a 200-megapixel main lens, as well as a 10-megapixel telephoto sensor, 12-megapixel ultra-wide and two 10-megapixel front cameras on both the cover screen and on the main display. Samsung's new Fold generation is, nevertheless, much more limited than other devices in the market when it comes to battery capacity. The Galaxy Z Fold 7 has a 4,400 milliampere-hour (mAh) battery -- far less than the 6,100 mAh power pack in Honor's Magic V5's or the Oppo Find N5's 5,600 mAh battery. Samsung says its device is capable of 24 hours of video playback. Samsung's Galaxy Z Flip 7 is also thinner than its predecessor, coming in at 6.5 millimeters when opened flat. By contrast, the Galaxy Z Flip 6 has a depth of 6.9 millimeters when unfolded. The new phone has a 4.1-inch cover screen and a 6.9-inch main display. It comes with a 50-megapixel main camera and 12-megapixel ultra-wide sensor on the back and a 10-megapixel lens on the main display. It also has a bigger 4,300 mAh battery, which Samsung says supports 31 hours of video playtime on a single charge. In addition to Flip 7, Samsung is also introducing a cheaper version of the phone, called the Galaxy Z Flip 7 FE, which is slightly smaller and thicker than its more premium counterpart. What about the AI features, you ask? They all include various AI-driven camera tools that can identify and suggest removal of unwanted people or objects in photos, and an audio eraser that filters out background noise in videos. The Galaxy Z Flip 7 also integrates Gemini Live, allowing users to overlay the AI assistant during live video recordings -- for instance, to receive real-time outfit suggestions. The Z Fold 7 starts at $1,999, and the Z Flip 7 starts at $1,099. Meanwhile, the Flip 7 FE is priced at $899.

McDonald's AI Hiring Bot Exposed Millions of Applicants' Data To Hackers

Wed, 2025-07-09 23:20
An anonymous reader quotes a report from Wired: If you want a job at McDonald's today, there's a good chance you'll have to talk to Olivia. Olivia is not, in fact, a human being, but instead an AI chatbot that screens applicants, asks for their contact information and resume, directs them to a personality test, and occasionally makes them "go insane" by repeatedly misunderstanding their most basic questions. Until last week, the platform that runs the Olivia chatbot, built by artificial intelligence software firm Paradox.ai, also suffered from absurdly basic security flaws. As a result, virtually any hacker could have accessed the records of every chat Olivia had ever had with McDonald's applicants -- including all the personal information they shared in those conversations -- with tricks as straightforward as guessing the username and password "123456." On Wednesday, security researchers Ian Carroll and Sam Curryrevealedthat they found simple methods to hack into the backend of the AI chatbot platform on McHire.com, McDonald's website that many of its franchisees use to handle job applications. Carroll and Curry, hackers with along track record of independent security testing, discovered that simple web-based vulnerabilities -- including guessing one laughably weak password -- allowed them to access a Paradox.ai account and query the company's databases that held every McHire user's chats with Olivia. The data appears to include as many as 64 million records, including applicants' names, email addresses, and phone numbers. Carroll says he only discovered that appalling lack of security around applicants' information because he was intrigued by McDonald's decision to subject potential new hires to an AI chatbot screener and personality test. "I just thought it was pretty uniquely dystopian compared to a normal hiring process, right? And that's what made me want to look into it more," says Carroll. "So I started applying for a job, and then after 30 minutes, we had full access to virtually every application that's ever been made to McDonald's going back years." Paradox.ai confirmed the security findings, acknowledging that only a small portion of the accessed records contained personal data. The company stated that the weak-password account ("123456") was only accessed by the researchers and no one else. To prevent future issues, Paradox is launching a bug bounty program. "We do not take this matter lightly, even though it was resolved swiftly and effectively," Paradox.ai's chief legal officer, Stephanie King, told WIRED in an interview. "We own this." In a statement to WIRED, McDonald's agreed that Paradox.ai was to blame. "We're disappointed by this unacceptable vulnerability from a third-party provider, Paradox.ai. As soon as we learned of the issue, we mandated Paradox.ai to remediate the issue immediately, and it was resolved on the same day it was reported to us," the statement reads. "We take our commitment to cyber security seriously and will continue to hold our third-party providers accountable to meeting our standards of data protection."

AMD Warns of New Meltdown, Spectre-like Bugs Affecting CPUs

Wed, 2025-07-09 22:41
AMD is warning users of a newly discovered form of side-channel attack affecting a broad range of its chips that could lead to information disclosure. Register: Akin to Meltdown and Spectre, the Transient Scheduler Attack (TSA) comprises four vulnerabilities that AMD said it discovered while looking into a Microsoft report about microarchitectural leaks. The four bugs do not appear too venomous at face value -- two have medium-severity ratings while the other two are rated "low." However, the low-level nature of the exploit's impact has nonetheless led Trend Micro and CrowdStrike to assess the threat as "critical." The reasons for the low severity scores are the high degree of complexity involved in a successful attack -- AMD said it could only be carried out by an attacker able to run arbitrary code on a target machine. It affects AMD processors (desktop, mobile and datacenter models), including 3rd gen and 4th gen EPYC chips -- the full list is here.

Microsoft Touts $500 Million in AI Savings While Slashing Jobs

Wed, 2025-07-09 22:02
Microsoft is keen to show employees how much AI is transforming its own workplace, even as the company terminates thousands of personnel. From a report: During a presentation this week, Chief Commercial Officer Judson Althoff said artificial intelligence tools are boosting productivity in everything from sales and customer service to software engineering, according to a person familiar with his remarks. Althoff said AI saved Microsoft more than $500 million last year in its call centers alone and increased both employee and customer satisfaction, according to the person, who requested anonymity to discuss an internal matter. The company is also starting to use AI to handle interactions with smaller customers, Althoff said. This effort is nascent, but already generating tens of millions of dollars, he said.

Animal Diseases Leapt To Humans When We Started Keeping Livestock

Wed, 2025-07-09 18:48
Researchers analyzing DNA from 1,313 ancient humans across Eurasia found that zoonotic pathogens first appeared in human populations around 6,500 years ago, coinciding with the transition from hunter-gatherer societies to livestock farming. The genomic study, published in Nature, identified 5,486 DNA sequences from bacteria, viruses and parasites in blood remnants from bones and teeth spanning 37,000 years. Zoonotic pathogens were detected only in remains 6,500 years old or younger, peaking around 5,000 years ago when pastoralist communities from the Steppe region migrated into Europe with large herds. The plague bacterium Yersinia pestis first appears in the dataset between 5,700-5,300 years ago.

Restaurants, Bars Say They're Getting Squeezed by Rising Music Licensing Costs

Wed, 2025-07-09 18:05
Restaurants and bars face mounting financial pressure from music licensing fees as the number of Performing Rights Organizations has expanded from three dominant players to at least six nationwide. The National Restaurant Association reports members pay an average of $4,500 annually for music licenses, representing 0.5% of total sales for small establishments. Hotels have experienced even steeper increases, with one major chain seeing costs rise 200% from 2021-2025, and some properties facing 400% jumps. The proliferation stems from streaming's revenue surge, which attracted new PROs seeking market share. Since many songs involve multiple songwriters affiliated with different organizations, venues must secure licenses from each PRO or risk lawsuits carrying penalties up to $150,000 per infringement.

Court Nullifies 'Click-To-Cancel' Rule That Required Easy Methods of Cancellation

Wed, 2025-07-09 17:25
A federal appeals court struck down a "click-to-cancel" rule that would have required companies to make cancelling services as easy as signing up. The Federal Trade Commission rule was scheduled to take effect on July 14 but was vacated by the US Court of Appeals for the 8th Circuit. The three-judge panel ruled unanimously that the Biden-era FTC failed to follow the full rulemaking process required under US law. The FTC is required to conduct a preliminary regulatory analysis when a rule has an estimated annual economic effect of $100 million or more. The FTC initially estimated the rule would not reach that threshold, but an administrative law judge later found compliance costs would exceed $100 million. Despite this finding, the FTC did not conduct the required preliminary analysis.

Record-Setting Dark Matter Detector Comes Up Empty -- and That's Good News

Wed, 2025-07-09 15:00
An anonymous reader quotes a report from Gizmodo: WIMPs (weakly interacting massive particles) are one of the most serious contenders for dark matter -- the "missing" mass supposedly constituting 85% of our universe. Given its elusiveness, dark matter tests the patience and creativity of physicists. But the latest results from LUX-ZEPLIN (LZ), the South Dakota-based detector, may have brought scientists a small step closer to catching WIMPs in action. In a recent Physical Review Letters paper, scientists analyzed 280 days' worth of data from LUX-ZEPLIN, reporting the tightest ever upper limit on the interaction strength of WIMPs. The result -- a near fivefold improvement -- demonstrates how physicists are increasingly getting better at circumventing the problem that dark matter is, well, dark; the elusive stuff evades any detection method that depends on materials interacting with visible light or other types of radiation. The LUX-ZEPLIN experiment, located one mile underground in a decommissioned South Dakota gold mine, employs nearly 15,000 pounds (7 tons) of liquid xenon. The chemical element's high atomic mass and density make it potentially easier for scientists to detect any unknown particles that may pass through the detector. Also, liquid xenon is transparent, preventing any unwanted noise -- usually arising from radioactive matter around the detector -- from spoiling an experiment. "These results firmly establish that LZ is the world's most sensitive search for dark matter heavier than 10 GeV, that's about 10 times heavier than a proton," explained Scott Haselschwart, a physicist at the University of Michigan and LZ physics coordinator, in an email to Gizmodo. "To put our result in perspective: we have ruled out dark matter that would interact only once in a single kilogram of xenon every four millennia!" "LZ is the most sensitive search for WIMP dark matter to date, but we still have another two years of data to collect," Haselschwart said. "This means that a discovery of dark matter in LZ could come anytime now. We are truly looking for dark matter where no one has ever looked before and that is extremely exciting!"

UK Police Dangle $102 Million To Digitize Its VHS Tape Archives

Wed, 2025-07-09 12:00
The UK police plan to spend up to 75 million pounds ($102 million) to digitize their vast archive of VHS tapes, aiming to preserve evidence by converting analog media into digital files integrated with evidence management systems. The procurement includes both in-house solutions and outsourced services, with additional funding earmarked for converting other legacy formats like microfiche and DVDs. The Register reports: According to a tender notice published last week, Bluelight Commercial - a not-for-profit buyer that acts on behalf of the emergency services - says the police force requires either in-house technology or outsourced services to convert the arcane magnetic tape format to digital storage. The notice, which sets out procurement plans, says the framework agreement will help forces with the "conversion of analog media to digital records, including metadata for integration with a digital evidence management system." In the first lot of the framework, Bluelight asks for in-house VHS media digitization software, hardware, and training to "enable a Police Force to convert VHS tapes to digital files." This chunk of the arrangement could be worth 50 million pounds ($68 million) for four years, excluding VAT. The second lot asks for outsourced VHS media digitization "for the provision of conversion services delivered completely by a third party with electronic files being returned securely to the customer force." The output is also set to be ingested by a digital evidence management solution. It could be worth up to 25 million pounds ($34 million) over the same period. In addition, Bluelight Commercial is looking for a provider to help with more niche media digitization, including converting microfiche, CD, DVDs to an electronic file format, in an arrangement which could be worth a total of up to 25 million pounds ($34 million).

Chinese Satellites Complete First High-Altitude Rendezvous For Possible Groundbreaking Refueling

Wed, 2025-07-09 09:00
Two Chinese satellites, SJ-25 and SJ-21, have reportedly completed the first autonomous high-altitude orbital docking. "Although unconfirmed, this is thought to be the first orbital refueling at such a height -- the two satellites are currently over 20,000 miles from Earth," reports ExtremeTech. From the report: Orbital refueling is an important component in keeping satellites and space stations in low Earth orbit flying, but any efforts beyond that have been merely speculative until the past few years, when serious efforts from a range of private and national entities have explored its possibilities. China may have gotten ahead of the curve with this latest docking, though, in an impressive world first that raises serious concerns for satellites from nations and entities that align themselves differently from China's goals and ambitions. In January, a satellite designated SJ-25 was launched "for the verification of satellite fuel replenishment and life extension service technologies," according to the Chinese state-owned designer, Shanghai Academy of Spaceflight Technology (via Ars Technica). Sometime last week, it matched orbits with the SJ-21 satellite, which previously conducted space debris maneuvering tests in 2021 and has remained in a geosynchronous orbit ever since. Last week, the two satellites matched orbits and seemingly docked together. Analysts believe the newer SJ-25 has likely proven refueling is possible even for geosynchronous satellites without the need for a manned crew to facilitate it. In an effort to prove this, two US Space Force's inspector satellites have positioned themselves in closer orbits to SJ-25 and SJ-21 for improved optics. [...] China continues to suggest these missions are part of a debris clean-up program, though it hasn't publicly made any statements about the recent alleged docking and refueling to celebrate its successes. If it doesn't, the only way we'll know if a refueling maneuver was successful is if the SJ-21 satellite unshackles from its younger sibling and performs fuel-demanding maneuvers that its previously estimated fuel levels shouldn't allow for.
