The Rust community has "recognized the unsafety of Rust (if used incorrectly)," according to a blog post by Amazon Web Services.

So now AWS and the Rust Foundation are "crowdsourcing an effort to verify the Rust standard library," according to an article at DevClass.com, "by setting out a series of challenges for devs and offering financial rewards for solutions..." Rust includes ways to bypass its safety guarantees though, with the use of the "unsafe" keyword... The issue AWS highlights is that even if developers use only safe code, most applications still depend on the Rust standard library. AWS states that there are approximately 7.5K unsafe functions in the Rust Standard Library and notes that 57 "soundness issues" and 20 CVEs (Common Vulnerabilities and Exposures) have been reported in the last three years. [28% of the soundness issues were discovered in 2024.]

Marking a function as unsafe does not mean it is vulnerable, only that Rust does not guarantee its safety. AWS plans to reduce the risk by using tools and techniques for formal verification of key library code, but believes that "a single team would be unable to make significant inroads" for reasons including the lack of a verification mechanism in the Rust ecosystem and what it calls the "unknowns of scalable verification." The plan therefore is to turn this over to the community, by posing challenges and rewarding developers for solutions.... A GitHub repository provides a fork of the Rust code and includes a set of challenges, currently 13 of them... The Rust Foundation says that there is a financial reward tied to each challenge, and that the "challenge rewards committee is responsible for reviewing activity and dispensing rewards." How much will be paid though is not stated.

Despite the wide admiration for Rust, there is no formal specification for the language, an issue which impacts formal verification efforts.

China's air force showcased a suite of new armaments this week, including a new stealth fighter and an attack drone, demonstrating its advancing ability to challenge the U.S. military presence in the Asia Pacific. From a report: The public debut of the J-35A stealth fighter and other weapons systems at China's premier airshow, which started Tuesday, represent the centerpiece in the Chinese air force's celebrations of its 75th anniversary -- a milestone in Chinese leader Xi Jinping's sweeping campaign to modernize the People's Liberation Army.

A single J-35A soared over crowds of spectators in a brief flypast on the opening day of Airshow China in the southern city of Zhuhai, making a steep climb with afterburners before rolling away and streaking out of view, state television footage showed. Other new weapons -- including the "Jiu Tian" reconnaissance and attack drone and the HQ-19 anti-ballistic-missile system -- were also prominent in ground displays at the biennial airshow, as examples of the PLA's growing prowess in aerial warfare and air defense. Much remains unclear about these systems and their capabilities. Even so, Chinese officials and state media say the new armaments reflect the significant advances that Beijing has made in developing its air power and enhancing its ability to defend China's strategic interests.

Analogue, a retro gaming company, is releasing a hardware-emulated Nintendo 64 console that can play every N64 game in 4K resolution. TechCrunch reports: Analogue, as is its habit, spent years meticulously re-engineering the N64 in FPGA form -- basically, this means that the new 3D console is, in several important ways, indistinguishable from the original hardware. One hundred percent compatibility with the console's game library is the most obvious one, meaning every single N64 cartridge works with this thing. Perhaps the bigger challenge with the N64, as with many other consoles of that era, is how it produces an image.

The N64 put out an analog video signal intended for display on interlaced CRT displays -- something that directly influenced the gameplay and art styles of countless games for the platform. Many retro games simply look bad on modern high-resolution displays not because they are dated or the art is insufficient, but because the display techs are fundamentally different.

To that end, Analogue has built in a native upscaler that, rather than cleaning up and digitizing the analog video output of the original system (as some upscalers do, with varying degrees of success), produces a natively digital, 4K signal with imitation CRT artifacts and scanlines. This is something they pioneered early on and produced several versions of to reproduce accurate phosphors and display modes for the multi-system Analogue Pocket. [...] The result is simply that games ought to look how you remembered them, which is to say probably a sight better than they actually looked. The Analogue 3D is available for pre-order at 8am PDT on October 21. It's priced at $250.

A new study reveals that the human sense of smell is far more sensitive than previously thought, capable of distinguishing odors and their sequences within just 60 milliseconds. CNN reports: In a single sniff, the human sense of smell can distinguish odors within a fraction of a second, working at a level of sensitivity that is "on par" with how our brains perceive color, "refuting the widely held belief that olfaction is our slow sense," a new study finds. Humans also can discern between various sequences of odors -- distinguishing a sequence of "A" before "B" from sequence "B" before "A" -- when the interval between odorant A and odorant B is merely 60 milliseconds, according to the study, published Monday in the journal Nature Human Behavior. [...]

The new findings challenge previous research in which the timing it took to discriminate between odor sequences was around 1,200 milliseconds, Dr. Dmitry Rinberg, a professor in the Department of Neuroscience and Physiology at NYU Langone Health in New York, wrote in an editorial accompanying the study in Nature Human Behavior. "The timing of individual notes in music is essential for conveying meaning and beauty in a melody, and the human ear is very sensitive to this. However, temporal sensitivity is not limited to hearing: our sense of smell can also perceive small temporal changes in odor presentations," he wrote. "Similar to how timing affects the perception of notes in a melody, the timing of individual components in a complex odor mixture that reaches the nose may be crucial for our perception of the olfactory world."

The ability to tell apart odors within a single sniff might be an important way in which animals detect both what a smell is and where it might be in space, said Dr. Sandeep Robert Datta, a professor in the Department of Neurobiology at Harvard Medical School, who was not involved in the new study. "The demonstration that humans can tell apart smells as they change within a sniff is a powerful demonstration that timing is important for smell across species, and therefore is a general principle underlying olfactory function. In addition, this study sheds important light on the mysterious mechanisms that support human odor perception," Datta wrote in an email. "The study of human olfaction has historically lagged that of vision and hearing, because as humans we think of ourselves as visual creatures that largely use speech to communicate," he said, adding that the new study helps "fill a critical gap in our understanding of how we as humans smell."

Ars Technica's Dan Goodin reports: Last week, NIST released its second public draft of SP 800-63-4, the latest version of its Digital Identity Guidelines. At roughly 35,000 words and filled with jargon and bureaucratic terms, the document is nearly impossible to read all the way through and just as hard to understand fully. It sets both the technical requirements and recommended best practices for determining the validity of methods used to authenticate digital identities online. Organizations that interact with the federal government online are required to be in compliance. A section devoted to passwords injects a large helping of badly needed common sense practices that challenge common policies. An example: The new rules bar the requirement that end users periodically change their passwords. This requirement came into being decades ago when password security was poorly understood, and it was common for people to choose common names, dictionary words, and other secrets that were easily guessed.

Since then, most services require the use of stronger passwords made up of randomly generated characters or phrases. When passwords are chosen properly, the requirement to periodically change them, typically every one to three months, can actually diminish security because the added burden incentivizes weaker passwords that are easier for people to set and remember. Another requirement that often does more harm than good is the required use of certain characters, such as at least one number, one special character, and one upper- and lowercase letter. When passwords are sufficiently long and random, there's no benefit from requiring or restricting the use of certain characters. And again, rules governing composition can actually lead to people choosing weaker passcodes.

The latest NIST guidelines now state that:
- Verifiers and CSPs SHALL NOT impose other composition rules (e.g., requiring mixtures of different character types) for passwords and
- Verifiers and CSPs SHALL NOT require users to change passwords periodically. However, verifiers SHALL force a change if there is evidence of compromise of the authenticator. ("Verifiers" is bureaucrat speak for the entity that verifies an account holder's identity by corroborating the holder's authentication credentials. Short for credential service provider, "CSPs" are a trusted entity that assigns or registers authenticators to the account holder.) In previous versions of the guidelines, some of the rules used the words "should not," which means the practice is not recommended as a best practice. "Shall not," by contrast, means the practice must be barred for an organization to be in compliance. Several other common sense practices mentioned in the document include: 1. Verifiers and CSPs SHALL require passwords to be a minimum of eight characters in length and SHOULD require passwords to be a minimum of 15 characters in length.
2. Verifiers and CSPs SHOULD permit a maximum password length of at least 64 characters.
3. Verifiers and CSPs SHOULD accept all printing ASCII [RFC20] characters and the space character in passwords.
4. Verifiers and CSPs SHOULD accept Unicode [ISO/ISC 10646] characters in passwords. Each Unicode code point SHALL be counted as a single character when evaluating password length.
5. Verifiers and CSPs SHALL NOT impose other composition rules (e.g., requiring mixtures of different character types) for passwords.
6. Verifiers and CSPs SHALL NOT require users to change passwords periodically. However, verifiers SHALL force a change if there is evidence of compromise of the authenticator.
7. Verifiers and CSPs SHALL NOT permit the subscriber to store a hint that is accessible to an unauthenticated claimant.
8. Verifiers and CSPs SHALL NOT prompt subscribers to use knowledge-based authentication (KBA) (e.g., "What was the name of your first pet?") or security questions when choosing passwords.
9. Verifiers SHALL verify the entire submitted password (i.e., not truncate it).

"Houston resident Brandy Deason put an Apple AirTag in her recycling to see where her plastic trash was going," writes Tom's Hardware.

"While many might expect the city would drop the recyclables off at a recycling center, Deason instead found her trash sitting in an open-air lot alongside millions of other pieces of trash at Wright Waste Management." Wright Waste Management did not allow CBS News to enter and inspect its premises. Still, the news team's drone camera discovered that all the trash picked up from the Houston Recycling Collaboration (HRC) was apparently just sitting there on its premises, stacked more than 10 feet high. This came as a shock, as the HRC was meant to revolutionize the city's recycling program, allowing it to process all kinds of plastic. Instead, we see all the collected waste sitting idle in open-air lots waiting for the right technology to appear.

That's because [Exxon-funded] Cyclix International, one of the partners in the HRC, has yet to open its massive factory to scale up its plastic recycling operation. The company said that it recycles all kinds of plastic and has even already set aside a sprawling space big enough to accommodate nine football fields. However, the current facility is just an empty husk without a single piece of machinery in sight.
Deason included 12 airtags in bags of recycling — and nine of them ended up at the HRC facility (with another one going to the local dump). In a video report, CBS News asked Deason what they thought about household recycling ended up in massive piles of plastic. "I thought it was kind of strange, because if you store plastic outside in the heat, it's a fire problem." In fact, that facility has already failed three fire-safety inspections by the county, according to CBS News. And while the facility has "applied" for approval to store plastic waste, that application has not yet been approved.

CBS asked a Cyclix project manager about the piles of unprocessed plastic sitting in the sun. "We need a huge supply of plastics to get ready for startup here," a spokesperson answered, "And we want to start that now in order to get ahead of it."

CBS's interviewer also raised another issue: the facility's plan is to recycle some of the plastic products into fuel. "So if you turn plastic waste into fuel that is then burned and creates greenhouse gas emissions, that's just another environmental problem."

Cyclix Project Manager: "Plastic waste is the challenge. So if we have the ability to take plastic waste and convert it to new products — that's what we're trying to do!"

CBS News points out that turning plastics into burn-able fuel is considered "recycling" by 25 states...

OpenAI is launching an online search tool in a direct challenge to Google, opening up a new front in the tech industry's race to commercialise advances in generative artificial intelligence. From a report: The experimental product, known as SearchGPT [non-paywalled], will initially only be available to a small group of users, with the San Francisco-based company opening a 10,000-person waiting list to test the service on Thursday. The product is visually distinct from ChatGPT as it goes beyond generating a single answer by offering a rail of links -- similar to a search engine -- that allows users to click through to external websites.

[...] SearchGPT will "provide up-to-date information from the web while giving you clear links to relevant sources," according to OpenAI. The new search tool will be able to access sites even if they have opted out of training OpenAI's generative AI tools, such as ChatGPT.

2017 Slashdot headline: "People Keep Finding Hidden Cameras in Their Airbnbs."

Nearly seven years later, CNN launched their own investigation of "Airbnb's hidden camera problem". CNN: "Across North America, police have seized thousands of images from hidden cameras at Airbnb rentals, including people's most intimate moments... It's more than just a few reported cases. And Airbnb knows it's a problem. In this deposition reviewed by CNN, an Airbnb rep said 35,000 customer support tickets about security cameras or recording devices had been documented over a decade. [The deposition estimates "about" 35,000 tickets "within the scope of the security camera and recording devices policy."]

Airbnb told CNN a single complaint can involve multiple tickets.
CNN actually obtained the audio recording of an Airbnb host in Maine admitting to police that he'd photographed a couple having sex using a camera hidden in a clock — and also photographed other couples. And one Airbnb guest told CNN he'd only learned he'd been recorded "because police called him, months later, after another guest found the camera" — with police discovering cameras in every single room in the house, concealed inside smoke detectors. "Part of the challenge is that the technology has gotten so advanced, with these cameras so small that you can't even see them," CNN says.

But even though recording someone without consent is illegal in every state, CNN also found that in this case and others, Airbnb "does not contact law enforcement once hidden cameras are discovered — even if children are involved." Their reporter argues that Airbnb "not only fails to protect its guests — it works to keep complaints out of the courts and away from the public."

They spoke to two Florida attorneys who said trying to sue Airbnb if something goes wrong is extremely difficult — since its Terms of Service require users to assume every risk themselves. "The person going to rent the property agrees that if something happens while they're staying at this accommodation, they're actually prohibited from suing Airbnb," says one of the attorneys. "They must go a different route, which is a binding arbitration." (When CNN asked if this was about controlling publicity, the two lawyers answered "absolutely" and "100%".) And when claims are settled, CNN adds, "Airbnb has required guests to sign confidentiality agreements — which CNN obtained — that keep some details of legal cases private."

Responding to the story, Airbnb seemed to acknowledge guests have been secretly recorded by hosts, by calling such occurrences "exceptionally rare... When we do receive an allegation, we take appropriate, swift action, which can include removing hosts and listings that violate the policy.

"Airbnb's trust and safety policies lead the vacation rental industry..."

"After approximately seven years in development, the Eclipse Foundation's Theia IDE project is now generally available," writes ADT magazine, "emerging from beta to challenge Microsoft's similar Visual Studio Code (VS Code) editor." The Eclipse Theia IDE is part of the Eclipse Cloud DevTools ecosystem. The Eclipse Foundation calls it "a true open-source alternative to VS Code," which was built on open source but includes proprietary elements, such as default telemetry, which collects usage data...

Theia was built on the same Monaco editor that powers VS Code, and it supports the same Language Server Protocol (LSP) and Debug Adapter Protocol (DAP) that provide IntelliSense code completions, error checking and other features. The Theia IDE also supports the same extensions as VS Code (via the Open VSX Registry instead of Microsoft's Visual Studio Code Marketplace), which are typically written in TypeScript and JavaScript. There are many, many more extensions available for VS Code in Microsoft's marketplace, while "Extensions for VS Code Compatible Editors" in the Open VSX Registry number 3,784 at the time of this writing...

The Eclipse Foundation emphasized another difference between its Theia IDE and VS Code: the surrounding ecosystem/community. "At the core of Theia IDE is its vibrant open source community hosted by the Eclipse Foundation," the organization said in a news release. "This ensures freedom for commercial use without proprietary constraints and fosters innovation and reliability through contributions from companies such as Ericsson, EclipseSource, STMicroelectronics, TypeFox, and more. The community-driven model encourages participation and adaptation according to user needs and feedback."

Indeed, the list of contributors to and adopters of the platform is extensive, also featuring Broadcom, Arm, IBM, Red Hat, SAP, Samsung, Google, Gitpod, Huawei and many others.
The It's FOSS blog has some screenshots and a detailed rundown.

ADT magazine stresses that there's also an entirely distinct (but related) project called the Eclipse Theia Platform (not IDE) which differs from VS Code by allowing developers "to create desktop and cloud IDEs using a single, open-source technology stack" [that can be used in open-source initiatives]. The Eclipse Theia platform "allows developers to customize every aspect of the IDE without forking or patching the code... fully tailored for the needs of internal company projects or for commercial resale as a branded product."

An anonymous reader quotes an op-ed written by Kenneth Roth, former executive director of Human Rights Watch (1993-2022) and a visiting professor at Princeton's School of Public and International Affairs: Julian Assange's lengthy detention has finally ended, but the danger that his prosecution poses to the rights of journalists remains. As is widely known, the U.S. government's pursuit of Assange under the Espionage Act threatens to criminalize common journalistic practices. Sadly, Assange's guilty plea and release from custody have done nothing to ease that threat. That Assange was indicted under the Espionage Act, a U.S. law designed to punish spies and traitors, should not be considered the normal course of business. Barack Obama's justice department never charged Assange because it couldn't distinguish what he had done from ordinary journalism. The espionage charges were filed by the justice department of Donald Trump. Joe Biden could have reverted to the Obama position and withdrawn the charges but never did.

The 18-count indictment filed under Trump accused Assange of having solicited secret U.S. government information and encouraged Chelsea Manning to provide it. Manning committed a crime when she delivered that information because she was a government employee who had pledged to safeguard confidential information on pain of punishment. But Assange's alleged solicitation of that information, and the steps he was said to have taken to ensure that it could be transferred anonymously, are common procedure for many journalists who report on national security issues. If these practices were to be criminalized, our ability to monitor government conduct would be seriously compromised. To make matters worse, someone accused under the Espionage Act is not allowed to argue to a jury that disclosures were made in the public interest. The unauthorized disclosure of secret information deemed prejudicial to national security is sufficient for conviction regardless of motive.

To justify Espionage Act charges, the Trump-era prosecutors stressed that Assange was accused of not only soliciting and receiving secret government information but also agreeing to help crack a password that would provide access to U.S. government files. That is not ordinary journalistic behavior. An Espionage Act prosecution for computer hacking is very different from a prosecution for merely soliciting and receiving secret information. Even if it would not withdraw the Trump-era charges, Biden's justice department could have limited the harm to journalistic freedom by ensuring that the alleged computer hacking was at the center of Assange's guilty plea. In fact, it was nowhere to be found. The terms for the proceeding were outlined in a 23-page "plea agreement" filed with the U.S. District Court for the Northern Mariana Islands, where Assange appeared by consent. Assange agreed to plead guilty to a single charge of violating the Espionage Act, but under U.S. law, it is not enough to plead in the abstract. A suspect must concede facts that would constitute an offense. "One effect of the guilty plea is that there will be no legal challenge to the prosecution, and hence no judicial decision on whether this use of the Espionage Act violates the freedom of the media as protected by the first amendment of the U.S. constitution," notes Roth. "That means that just as prosecutors overreached in the case of Assange, they could do so again."

"[M]edia protections are not limited to journalists who are deemed responsible. Nor do we want governments to make judgments about which journalists deserve First Amendment safeguards. That would quickly compromise media freedom for all journalists."

Roth concludes: "Imperfect journalist that he was, Assange should never have been prosecuted under the Espionage Act. It is unfortunate that the Biden administration didn't take available steps to mitigate that harm."

wgoodman shares a report from The Register: NASA's Voyager 1 spacecraft is back in action and conducting normal science operations for the first time since the veteran probe began spouting gibberish at the end of 2023. All four of the spacecraft's remaining operational instruments are now returning usable data to Earth, according to NASA. Some additional work is needed to tidy up the effects of the issue. Engineers need to resynchronize the timekeeping software of Voyager 1's three onboard computers to ensure that commands are executed at the correct times. Maintenance will also be performed on the digital tape recorder, which records some data from the plasma instrument for a six-monthly downlink to Earth.

Voyager 1's woes began in November 2023, when the spacecraft stopped transmitting usable data back to Earth. Rather than engineering and science data, NASA found itself faced with a repeating pattern of ones and zeroes, as though the spacecraft was somehow stalled. Engineers reckoned the issue lay with the Flight Data System (FDS) and in March sent a command -- dubbed a "poke" -- to get the FDS to try some other software sequences and thus circumvent whatever was causing the problem. The result was a complete memory dump from the computer, which allowed engineers to pinpoint where the corruption had occurred. It appeared that a single chip was malfunctioning, and engineers were faced with the challenge of devising a software update that would work around the defective hardware.

Usable engineering data began to be returned later in April, and in May the mission team sent commands to instruct the probe to keep science data flowing. The result was that the plasma wave subsystem and magnetometer instrument began sending data immediately. According to NASA, the cosmic ray subsystem and low energy charged particle instrument required a little more tweaking but are now operational. The rescue was made all the more impressive by the fact that it takes 22.5 hours for a command to reach Voyager 1 and another 22.5 hours for a response to be received on Earth.

cusco writes: Indian space startup Agnikul used a 3-D printer from German company EOS to print an engine out of inconel, a high-performance nickel-chromium alloy, in one solid piece over the course of roughly 72 hours. While other companies like Relativity Space and Rocket Lab are using 3-D printers extensively, Agnikul's engine is unique in being printed in one go, rather than as multiple components that need to be stitched together. This approach significantly speeds up manufacturing time.

The single-engine technology demonstration rocket produced 6 kilonewtons of thrust and reached an altitude of 6.5 kilometers before splashing down into the ocean. The launch vehicle used was about 6 meters tall with a single engine, making it roughly equivalent to the second stage of the company's planned commercial product, Agnibaan. Agnibaan will be a two-stage rocket, 18 meters tall, featuring eight engines in total, and capable of carrying a 300-kilogram payload to an altitude of around 700 km. The company believes that their 3D printing approach opens the door to providing low-cost, "on-demand" launch services to operators of small satellites.

IEEE Spectrum adds: Assembling the rest of the rocket and integrating the engine took roughly two weeks. The company says that opens the door to providing low-cost, "on-demand" launch services to operators of small satellites, which otherwise need to wait for a ride share on a bigger rocket. The big challenge now will be going from a single engine to a cluster of seven on Agnibaan's first stage, says cofounder and CEO Srinath Ravichandran. This raises all kinds of challenges, from balancing thrust across the engines at lift-off to managing engine plume interactions when the engines gimbal to alter the trajectory. "But these are problems that people have figured out," he says. "We believe that we should just be able to fine-tune it for our mission and go." The company is currently building facilities to carry out ground tests of engine clusters, says Ravichandran, and is targeting its first orbital launch for this time next year.

An anonymous reader quotes a report from TechCrunch: A Finnish startup called Flow Computing is making one of the wildest claims ever heard in silicon engineering: by adding its proprietary companion chip, any CPU can instantly double its performance, increasing to as much as 100x with software tweaks. If it works, it could help the industry keep up with the insatiable compute demand of AI makers. Flow is a spinout of VTT, a Finland state-backed research organization that's a bit like a national lab. The chip technology it's commercializing, which it has branded the Parallel Processing Unit, is the result of research performed at that lab (though VTT is an investor, the IP is owned by Flow). The claim, Flow is first to admit, is laughable on its face. You can't just magically squeeze extra performance out of CPUs across architectures and code bases. If so, Intel or AMD or whoever would have done it years ago. But Flow has been working on something that has been theoretically possible -- it's just that no one has been able to pull it off.

Central Processing Units have come a long way since the early days of vacuum tubes and punch cards, but in some fundamental ways they're still the same. Their primary limitation is that as serial rather than parallel processors, they can only do one thing at a time. Of course, they switch that thing a billion times a second across multiple cores and pathways -- but these are all ways of accommodating the single-lane nature of the CPU. (A GPU, in contrast, does many related calculations at once but is specialized in certain operations.) "The CPU is the weakest link in computing," said Flow co-founder and CEO Timo Valtonen. "It's not up to its task, and this will need to change."

CPUs have gotten very fast, but even with nanosecond-level responsiveness, there's a tremendous amount of waste in how instructions are carried out simply because of the basic limitation that one task needs to finish before the next one starts. (I'm simplifying here, not being a chip engineer myself.) What Flow claims to have done is remove this limitation, turning the CPU from a one-lane street into a multi-lane highway. The CPU is still limited to doing one task at a time, but Flow's Parallel Processing Unit (PPU), as they call it, essentially performs nanosecond-scale traffic management on-die to move tasks into and out of the processor faster than has previously been possible. [...] Flow is just now emerging from stealth, with [about $4.3 million] in pre-seed funding led by Butterfly Ventures, with participation from FOV Ventures, Sarsia, Stephen Industries, Superhero Capital and Business Finland. The primary challenge Flow faces is that for its technology to be integrated, it requires collaboration at the chip-design level. This means chipmakers need to redesign their products to include the PPU, which is a substantial investment.

Given the industry's cautious nature and the existing roadmaps of major chip manufacturers, the uptake of this new technology might be slow. Companies are often reluctant to adopt unproven technologies that could disrupt their long-term plans.

Popular Science points out that for encoding data, "optical disks almost always offer just a single, 2D layer — that reflective, silver underside."

"If you could boost a disk's number of available, encodable layers, however, you could hypothetically gain a massive amount of extra space..." Researchers at the University of Shanghai for Science and Technology recently set out to do just that, and published the results earlier this week in the journal, Nature. Using a 54-nanometer laser, the team managed to record a 100 layers of data onto an optical disk, with each tier separated by just 1 micrometer. The final result is an optical disk with a three-dimensional stack of data layers capable of holding a whopping 1 petabit (Pb) of information — that's equivalent to 125,000 gigabytes of data...

As Gizmodo offers for reference, that same petabit of information would require roughly a six-and-a-half foot tall stack of HHD drives — if you tried to encode the same amount of data onto Blu-rays, you'd need around 10,000 blank ones to complete your (extremely inefficient) challenge.

To pull off their accomplishment, engineers needed to create an entirely new material for their optical disk's film... AIE-DDPR film utilizes a combination of specialized, photosensitive molecules capable of absorbing photonic data at a nanoscale level, which is then encoded using a high-tech dual-laser array. Because AIE-DDPR is so incredibly transparent, designers could apply layer-upon-layer to an optical disk without worrying about degrading the overall data. This basically generated a 3D "box" for digitized information, thus exponentially raising the normal-sized disk's capacity.

The great libraries of the ancient classical world are "legendary... said to have contained stacks of texts," writes ScienceAlert. But from Rome to Constantinople, Athens to Alexandria, only one collection survived to the present day.

And here in 2024, "we can now start reading its contents." A worldwide competition to decipher the charred texts of the Villa of Papyri — an ancient Roman mansion destroyed by the eruption of Mount Vesuvius — has revealed a timeless infatuation with the pleasures of music, the color purple, and, of course, the zingy taste of capers. The so-called Vesuvius challenge was launched a few years ago by computer scientist Brent Seales at the University of Kentucky with support from Silicon Valley investors. The ongoing 'master plan' is to build on Seales' previous work and read all 1,800 or so charred papyri from the ancient Roman library, starting with scrolls labeled 1 to 4.

In 2023, the annual gold prize was awarded to a team of three students, who recovered four passages containing 140 characters — the longest extractions yet. The winners are Youssef Nader, Luke Farritor, and Julian Schilliger. "After 275 years, the ancient puzzle of the Herculaneum Papyri has been solved," reads the Vesuvius Challenge Scroll Prize website. "But the quest to uncover the secrets of the scrolls is just beginning...." Only now, with the advent of X-ray tomography and machine learning, can their inky words be pulled from the darkness of carbon.
A few months ago students deciphered a single word — "purple," according to the article. But "That winning code was then made available for all competitors to build upon." Within three months, passages in Latin and Greek were blooming from the blackness, almost as if by magic. The team with the most readable submission at the end of 2023 included both previous finders of the word 'purple'. Their unfurling of scroll 1 is truly impressive and includes more than 11 columns of text. Experts are now rushing to translate what has been found. So far, about 5 percent of the scroll has been unrolled and read to date. It is not a duplicate of past work, scholars of the Vesuvius Challenge say, but a "never-before-seen text from antiquity."

One line reads: "In the case of food, we do not right away believe things that are scarce to be absolutely more pleasant than those which are abundant."

In a new video released today, Boston Dynamics' Atlas robot is shown performing "kinetically challenging" work, like moving some medium-weight car parts and precisely picking stuff up. Ars Technica reports: In the latest video, we're on to what looks like "phase 2" of picking stuff up -- being more precise about it. The old clamp hands had a single pivot at the palm and seemed to just apply the maximum grip strength to anything the robot picked up. The most delicate thing Atlas picked up in the last video was a wooden plank, and it was absolutely destroying the wood. Atlas' new hands look a lot more gentle than The Clamps, with each sporting a set of three fingers with two joints. All the fingers share one big pivot point at the palm of the hand, and there's a knuckle joint halfway up the finger. The fingers are all very long and have 360 degrees of motion, so they can flex in both directions, which is probably effective but very creepy. Put two fingers on one side of an item and the "thumb" on the other, and Atlas can wrap its hands around objects instead of just crushing them.

Atlas is picking up a set of car struts -- an object with extremely complicated topography that weighs around 30 pounds -- so there's a lot to calculate. Atlas does a heavy two-handed lift of a strut from a vertical position on a pallet, walks the strut over to a shelf, and carefully slides it into place. This is all in Boston Dynamics' lab, but it's close to repetitive factory or shipping work. Everything here seems designed to give the robot a manipulation challenge. The complicated shape of the strut means there are a million ways you could grip it incorrectly. The strut box has tall metal poles around it, so the robot needs to not bang the strut into the obstacle. The shelf is a tight fit, so the strut has to be placed on the edge of the shelf and slid into place, all while making sure the strut's many protrusions won't crash into the shelf.

According to Reuters, Nvidia is designing ARM-based processors that would run Microsoft's Windows operating system. While they're not expected to be ready until 2025, it poses a major new challenge to Intel which has long dominated the PC industry. From the report: The AI chip giant's new pursuit is part of Microsoft's effort to help chip companies build Arm-based processors for Windows PCs. Microsoft's plans take aim at Apple, which has nearly doubled its market share in the three years since releasing its own Arm-based chips in-house for its Mac computers, according to preliminary third-quarter data from research firm IDC. Advanced Micro Devices also plans to make chips for PCs with Arm technology, according to two people familiar with the matter. Nvidia and AMD could sell PC chips as soon as 2025, one of the people familiar with the matter said. Nvidia and AMD would join Qualcomm, which has been making Arm-based chips for laptops since 2016. At an event on Tuesday that will be attended by Microsoft executives, including vice president of Windows and Devices Pavan Davuluri, Qualcomm plans to reveal more details about a flagship chip that a team of ex-Apple engineers designed, according to a person familiar with the matter.

Nvidia, AMD and Qualcomm's efforts could shake up a PC industry that Intel long dominated but which is under increasing pressure from Apple. Apple's custom chips have given Mac computers better battery life and speedy performance that rivals chips that use more energy. Executives at Microsoft have observed how efficient Apple's Arm-based chips are, including with AI processing, and desire to attain similar performance, one of the sources said. Microsoft has been encouraging the involved chipmakers to build advanced AI features into the CPUs they are designing. The company envisions AI-enhanced software such as its Copilot to become an increasingly important part of using Windows. To make that a reality, forthcoming chips from Nvidia, AMD and others will need to devote the on-chip resources to do so. "Microsoft learned from the 90s that they don't want to be dependent on Intel again, they don't want to be dependent on a single vendor," said Jay Goldberg, chief executive of D2D Advisory, a finance and strategy consulting firm. "If Arm really took off in PC (chips), they were never going to let Qualcomm be the sole supplier."

The stakes are high for Bethesda's newest role-playing game. Microsoft needs an Xbox hit, and players are hungry for an expansive and satisfying space adventure. From a report: Starfield almost immediately nudges its players to the edges of the cosmos. In the opening hours of the role-playing video game, it's possible to land your spaceship on Earth's moon or zip 16 light-years to Alpha Centauri. When you open your map and zoom out from a planet, you can behold its surrounding solar system; zoom out again, and you're scrolling past luminous stars and the mysterious worlds that orbit them. That sprawling celestial journey within Starfield, developed by Bethesda Game Studios, reveals both the tremendous potential and the monumental challenge of an open-world space adventure. Bethesda has hyped an expansive single-player campaign with 1,000 explorable planets. And expectations around the game, officially releasing on Sept. 6 after a 10-month delay, are nearly as vast.

It's the first new universe in 25 years for Bethesda, known for the Elder Scrolls and Fallout series. It's also a high-stakes moment for Microsoft, which makes the Xbox and has long faced criticism that it produces fewer hit games than its console rivals, Sony and Nintendo. To compete, Microsoft went on a spending spree, acquiring Bethesda's parent company in 2020 and agreeing to purchase Activision Blizzard in 2022, a $69 billion bet that is being challenged by regulators. Now Bethesda must deliver. Known for letting players navigate competing factions and undertake eccentric quests, the studio hopes Starfield will dazzle those clamoring for engaging encounters with alien life-forms or space mercenaries as well as a sense of boundless exploration.

Adyen's shares plunged as aggressive competition in North America contributed to the slowest revenue growth since its initial public offering, erasing more than $19.6 billion of market value in a single day. From a report: Shares of the Dutch payment processing company fell a record 40.6% to $950 at 4:49 p.m. in Amsterdam, the lowest since May 2020. Trading was temporarily halted due to volatility multiple times in the day. Pricing competition, higher inflation and interest rates stunted revenue growth in the first half, the Amsterdam-based fintech firm said on Thursday. Net sales rose 21% to $803 million in the period, compared to an estimate of $843 million in a Bloomberg survey of analysts. Adyen has been a reliable growth stock, with revenue rising by at least 26% in every half since its listing in 2018 until the latest period. The disappointing results, which were also hurt by inflation and rising interest rates, suggest maintaining such momentum will be a challenge.

An anonymous reader shared this report from the international tech news site Rest of World: In an open letter earlier this year, Neal Mohan, the recently appointed head of YouTube, made a pledge to creators that better translation tools were coming. Now, YouTube is delivering on that promise with Aloud — a free tool that automatically dubs videos using synthetic voices, raising creators' hopes and putting new pressure on dubbing firms that already cater to YouTubers.

At the VidCon convention in late June, YouTube announced a pilot for Aloud. The tool first generates a transcription of a video's audio, which a creator can edit before selecting their preferred language and style of synthetic voice. The dub can take just minutes to generate.

The pilot currently includes the option to dub videos into English, Spanish, and Portuguese. The company has said more languages are coming — likely including Bahasa Indonesia and Hindi, which are already advertised on the Aloud website. Hundreds of creators have already signed up to test the tool. "Our long-term goal is to be able to dub between any two languages, and as part of that goal we will continue to pilot and learn from dubbing content in different regions," Buddhika Kottahachchi, co-founder of Aloud and the recently appointed head of product for YouTube Dubbing, told Rest of World. "Helping a creator expand beyond their primary language can help them reach new audiences..."

In the lead up to the pilot announcement, YouTube also released a new product feature that allows viewers to select between multiple dubbing tracks on a single video, similar to the current option for subtitles.
Here's a video of YouTube's announcement, with five"audio tracks" (in different languages) available if you click the "gear" icon. While YouTube's top stars hire dubbing services, many smaller creators can't afford them, the article points out. "By offering Aloud for free, YouTube is setting up a new swath of creators to access dubs for the first time...

"YouTube's new push into automated dubbing is a serious challenge for existing dubbing companies, which are now forced to compete with a free competitor built into the platform."
