How Peter Jackson’s Beatles Documentary Used Custom AI To Remove Background Noise

Peter Jackson’s seven-hour documentary “Get Back” (now streaming on Disney+) edits footage from the Beatles’ ambitious recording sessions for their 1970 album Let It Be. But long-time Slashdot reader MattSparkes writes that the whole documentary “would have been impossible without custom-made artificial intelligence, say sound engineers.”
Sixty hours of footage were recorded but most of the audio was captured by a single microphone that picked up the musicians’ instruments in a noisy jumble rather than a carefully crafted mix. It also recorded background noise and chatter, which made much of the footage unusable.

The team scoured academic papers on using AI to separate audio sources but realised that none of the previous research would work for a music documentary. They consulted with Paris Smaragdis at the University of Chicago and started to create a neural network called MAL (machine assisted learning) and a set of training data that was higher quality than datasets used in academic experiments.
The Washington Post describes it as “a sort of sonic forensics,” adding that the name MAL was a deliberate homage to the HAL computer in 2001: a Space Odyssey — and to the Beatles’ beloved road manager and principal assistant, Mal Evans.
Using MAL, Jackson and his colleagues were able to painstakingly and precisely isolate each and every audio track — be it musical instrumentation, singing or studio chatter — from the original mono recordings made for most of “Let It Be.”

“What we’ve managed to do is split it all apart in a way that is utterly clean and sounds much better,” Jackson said.

Other interesting observations from the Post:

“Get Back” tapped nearly 120 hours of previously unheard audio recordings. Jackson and his team started work in 2017.
Jackson’s team also “carefully restored, upgraded and enlarged the grainy original 16-millimeter” footage from the 1969 documentary Let It Be “so that it now pops with vibrant color.”
Jackson’s documentary “was originally set to open in theaters last year as a two-and-a-half hour feature film, but was pushed back by the pandemic. With more time unexpectedly on his hands, Jackson transformed his feature film into the six-hour epic….”
Jackson would also like to release an expanded director’s cut sometime in the future, “but there are no current plans to do so.”
“At one point, Jackson’s favorite version of his Get Back film clocked in at 18 hours…”

New Era Begins: Construction Starts on 47-Acre Fusion Reactor Funded by Google and Bill Gates

Heating plasma fuel to over 100 million degrees Celsius to create inexpensive and unlimited zero-emissions electricity “has been compared to everything from a holy grail to fool’s gold…” writes the Boston Globe, “or an expensive delusion diverting scarce money and brainpower from the urgent needs of rapidly addressing climate change.”
[N]ow, after breakthroughs this year at MIT and elsewhere, scientists — and a growing number of deep-pocketed investors — insist that fusion is for real and could start sending power to electricity grids in about a decade.
To prove that, Commonwealth Fusion Systems, an MIT spinoff in Cambridge, is using a whopping $1.8 billion it raised in recent months from investors such as Bill Gates, Google, and a host of private equity firms to build a prototype of a specially designed fusion reactor on a former Superfund site in Devens. A host of excavators, backhoes, and other heavy machinery are clearing land there and laying concrete foundations on 47 acres of newly acquired land. “It may sound like science fiction, but the science of fusion is real, and the recent scientific advancements are game-changing,” said Dennis Whyte, director of MIT’s Plasma Science and Fusion Center and cofounder of Commonwealth Fusion Systems. “These advancements aren’t incremental; they are quantum leap improvements. . . . We’re in a new era of actually delivering real energy systems….”

There are now at least 35 companies trying to prove that fusion can be a practical power source, most of them established in the past decade, according to the three-year-old Fusion Industry Association. The promise of fusion was buoyed with significant developments this year. In May, scientists in China used their own specially designed tokamak to sustain a fusion reaction of 120 million degrees Celsius for 101 seconds, the longest on record. In September, Whyte’s team at MIT and his colleagues at Commonwealth Fusion Systems demonstrated that, while using relatively low-cost materials that don’t require a large amount of space, they could create the most powerful magnetic field of its kind on Earth, a critical component of the prototype reactor they’re building in Devens.

“We have come a long way,” said Bob Mumgaard, CEO of Commonwealth Fusion Systems, who compared their advance to similar breakthroughs that made flight possible. “We’re a pretty conservative science bunch, but we’re pretty confident.” With some $2 billion raised in recent years — more than any of the other fusion startups — his company is racing to prove that their prototype, called SPARC, will produce more energy than it consumes in 2025. If they succeed, the company plans to start building their first power plant several years afterward. Ultimately, he said, their goal is to help build 10,000 200-megawatt fusion power plants around the world, enough to replace nearly all fossil fuels. “This is a solution that can scale to the size of the problem that decarbonization requires,” he said.

Phil Warburg, a senior fellow at Boston University’s Institute for Sustainable Energy, disagrees. “Fusion has been an elusive fantasy for a half-century or more,” he tells the Boston Globe. “Along with the technical hurdles, the environmental downsides have not been seriously examined, and the economics are anything but proven… The current wave of excitement about fusion comes at a time when we’ve barely begun to tap the transformative potential of solar, wind, storage, and energy efficiency — all known to be technically viable, economically competitive, and scalable today. The environmental advocacy community needs to focus on vastly expanding those clean-energy applications, leaving fusion to the scientists until they’ve got something much more credible to show for their efforts.”

But Elizabeth Turnbull Henry, president of the Environmental League of Massachusetts rejected the argument that fusion research detracts from investments in renewables as a “false choice…. We’re at a very different moment now, and it’s good to have a lot of different horses in the race.”

The also article notes that officials at America’s Nuclear Regulatory Commission told them federal officials are already holding meetings to discuss how they’d regulate fusion reactors.

Large Ocean Fossil Discovered in Nevada Could Hold Key To Aquatic Evolution

An 8-foot-long skull discovered in the Augusta Mountains of Nevada is the largest fossil ever found from its time. The research team believes that the remarkable discovery could provide insight into how modern whales developed, and how to preserve their presence in our oceans. From a report: The fossil — a newly discovered species of ichthyosaur, a type of large aquatic reptile — dates to about 246 million years ago. The newly-named cymbospondylus youngorum is, according to the research team, the largest animal found from that time period, both in the sea and on land. It currently holds the title of the first giant animal to ever inhabit Earth. The well-preserved skull was excavated along with part of the creature’s backbone, shoulder and forefin. At more than 55 feet long, the ichthyosaur was estimated to be the size of a large sperm whale, according to the study released Thursday by the American Association for the Advancement of Science and the Natural History Museums of Los Angeles County. The ichthyosaur has an elongated snout and conical teeth, leading researchers to believe it ate squid and fish. It also could have hunted smaller marine reptiles and younger members of its species.

Russia Steps Up Pressure on Google, Meta With Record Fines

A Russian court fined Alphabet’s Google 7.2 billion rubles ($98 million) and Meta Platforms 2 billion rubles Friday for failing to remove banned content, the largest such penalties yet, as the authorities escalate a crackdown on foreign technology companies. From a report: The fines were due to the companies’ repeated failure to comply with orders to take down content and based on a percentage of their annual earnings in Russia, the federal communications watchdog said in a statement. Google and Meta could face more fines if they don’t remove the material, it said.

Google is studying the ruling and then will determine its next steps, the company’s press service in Moscow said in a statement. Russia has stepped up its confrontation with foreign social media and internet companies this year in what the government calls a campaign to uphold its digital sovereignty. Regulators have levied fines and slowed content in a bid to force companies including Google and Twitter to delete posts encouraging unauthorized protests and other material deemed illegal.

Toyota ‘Reviewing’ Key Fob Remote Start Subscription Plan After Massive Blowback

An anonymous reader shares a report: Earlier this month, we broke a story about Toyota locking its key fob remote start function behind a monthly subscription. If owners of certain models aren’t actively enrolled in a larger Toyota connected services plan, the proximity remote start function on the fob — that is, when you press the lock button three times to start the car while outside of it — will not work even though it sends the signal directly to the car. Obviously, this sent people into a frenzy whether they own a Toyota or not, because it was seen as a dark harbinger of the perils of fully-connected cars. Automakers now have the ability to nickel and dime people to death by charging ongoing subscription fees for functions that used to be a one-and-done purchase, and it looked like Toyota was hopping on the bandwagon.

At the time, Toyota declined to give us a detailed answer on why it chose to take a feature that doesn’t need an internet connection to function and moved it behind a paywall. Today, we’ve got answers. Toyota now claims it never intended to market the key fob remote start as a real feature, and it also says the subscription requirement was an inadvertent result of a relatively small technical decision related to the way its new vehicles are architectured. Finally, Toyota has heard the outrage over the last week — a spokesperson told us the company was caught off guard by the blowback — and its executive team is currently examining whether it’s possible to reverse course and drop the subscription requirement for key fob remote start.

Public Agencies Are Buying Up AI-Driven Hiring Tools and ‘Bossware’

Through public records requests, The Markup found more than 20 public agencies using the sometimes-controversial software. From the report: In 2020, the FDA’s Center for Drug Evaluation and Research (CDER) faced a daunting task: It needed to fill more than 900 job vacancies — and fast. The center, which does things like inspect pharmaceutical manufacturing facilities, was in the process of modernizing the FDA’s New Drugs Regulatory Program just as the pandemic started. It faced “a surge in work,” along with new constraints that have affected everyone during the pandemic, including travel limitations and lockdowns. So they decided to turn to an artificial intelligence tool to speed up the hiring, according to records obtained by The Markup. The center, along with the Office of Management and the Division of Management Services, the background section of a statement of work said, were developing a “recruitment plan to leverage artificial intelligence (AI) to assist in the time to hire process.”

The agency ultimately chose to use HireVue, an online platform that allows employers to review asynchronously recorded video interviews and have recruits play video games as part of their application process. Over the years the platform has also offered a variety of AI features to automatically score candidates. HireVue, controversially, used to offer facial analysis to predict whether an applicant would be a good fit for an open job. In recent years, research has shown that facial recognition software is racially biased. In 2019, the company’s continued use of the technique led one member of its scientific advisory board to resign. It has since stopped using facial recognition. The Markup used GovSpend, a database of procurement records for U.S. agencies at the state, local, and federal levels, to identify agencies that use HireVue. We also searched for agencies using Teramind and ActivTrak, both another kind of controversial software that allows employers to remotely monitor their workers’ browsing activities through screenshots and logs. The Markup contacted and filed public records requests with those 24 agencies to understand how they were using the software. Eleven public agencies, including the FDA, replied to The Markup with documents or confirmations that they had bought HireVue at some point since 2017. Of the six public agencies that replied to The Markup’s questions confirming that they actually used the software, all but one — Lake Travis Independent School District in Texas — confirmed they did not make use of the AI scoring features of the software. Documents and responses from 13 agencies confirmed that they purchased Teramind or ActivTrak at some point during the same time frame.

Virtual Guns in Videogames Could Soon Be Worth Real Money

Game makers are increasingly selling virtual weapons and gear as NFTs, extending the trendy digital deeds’ reach but rankling some players. From a report: More videogame makers are selling virtual guns, helmets and other gear in the form of NFTs, a move that is increasingly pushing the trendy digital deeds into the average household. Players have been paying for virtual goods in games like “Grand Theft Auto Online” and “World of Warcraft” for years, but turning those items into nonfungible tokens would let gamers trade and resell them, making them into potentially valuable assets. The change also could mean that players who buy an NFT in one game could use it later in other games, on social media and in other corners of the internet — an important step in developing an economy for the so-called metaverse. “FarmVille” maker Zynga and “Assassin’s Creed” creator Ubisoft Entertainment are among the first big, publicly traded gaming companies to say they are experimenting with the strategy. Electronic Arts, Playtika and others are also looking into NFTs’ potential use for engaging players.

“We’re doing this because this may be part of the future of gaming,” said Matt Wolf, Zynga’s new vice president of blockchain gaming. “This is all about community building.” Nonfungible tokens are essentially digital deeds that verify the authenticity of the items they represent as unique. They are the latest internet-based collecting craze, and so far they have come in forms ranging from digital artwork and trading cards to virtual real estate and sneakers, as well as concert tickets and even sports highlights. The tokens are stored on a blockchain, a digital ledger that shows when they were purchased and for how much, and ensures NFTs can’t be duplicated or changed. Amid all that activity, NFTs’ advent in videogames holds particular significance because gamers spend so much time in virtual worlds. That makes them potential early adopters in the metaverse — a virtual realm where proponents say people will work, play and shop and where technology experts say the ability to buy and sell NFTs will be key.

Second Ransomware Family Exploiting Log4j Spotted In US, Europe

Researchers say a second family of ransomware has been growing in usage for attack attempts that exploit the critical vulnerability in Apache Log4j, including in the U.S. and Europe. VentureBeat reports: A number of researchers, including at cybersecurity giant Sophos, have now said they’ve observed the attempted deployment of a ransomware family known as TellYouThePass. Researchers have described TellYouThePass as an older and largely inactive ransomware family — which has been revived following the discovery of the vulnerability in the widely used Log4j logging software. TellYouThePass is the second family of ransomware that’s been observed to exploit the vulnerability in Log4j, known as Log4Shell, joining the Khonsari ransomware, according to researchers.

While previous reports indicated that TellYouThePass was mainly being directed against targets in China, researchers at Sophos told VentureBeat that they’ve observed the attempted delivery of TellYouThePass ransomware both inside and outside of China — including in the U.S. and Europe. “Systems in China were targeted, as well as some hosted in Amazon and Google cloud services in the U.S. and at several sites in Europe,” said Sean Gallagher, a senior threat researcher at Sophos Labs, in an email to VentureBeat on Tuesday. Sophos detected attempts to deliver TellYouThePass payloads by utilizing the Log4j vulnerability on December 17 and December 18, Gallagher said. TellYouThePass has versions that run on either Linux or Windows, “and has a history of exploiting high-profile vulnerabilities like EternalBlue,” said Andrew Brandt, a threat researcher at Sophos, in an email. The Linux version is capable of stealing Secure Socket Shell (SSH) keys and can perform lateral movement, Brandt said. Sophos initially disclosed its detection of TellYouThePass ransomware in a December 20 blog post.

The first report of TellYouThePass ransomware exploiting the Log4j vulnerability appears to have come from the head of Chinese cybersecurity group KnownSec 404 Team on December 12. The attempted deployment of TellYouThePass in conjunction with Log4Shell was subsequently confirmed by additional researchers, according to researcher community Curated Intelligence. In a blog post Tuesday, Curated Intelligence said its members can now confirm that TellYouThePass has been seen exploiting the vulnerability “in the wild to target both Windows and Linux systems.” TellYouThePass had most recently been observed in July 2020, Curated Intelligence said. It joins Khonsari, a new family of ransomware identified in connection with exploits of the Log4j vulnerability.

New Policing System Will Send Drones To the Source of Gunshots

A new policing system is being developed that will send autonomous drones equipped with shot-locating technology to the source of gunshots. “By analyzing the live video from its onboard camera, police officers can then gain a better sense of the situation they’re heading into,” reports New Atlas. From the report: Already in use in over 120 cities in the US, South Africa and the Caribbean, the American ShotSpotter system utilizes a network of microphones within a neighborhood to detect “loud, impulsive sounds.” Whenever such a sound is detected, its geographical originating point can be triangulated by analyzing the millisecond differences in the times at which it was picked up by the different microphones — the closer a mic was to the gun, the earlier it will have detected the sound of that gun firing. That said, a combination of AI software and human staff (at a control center) is used to determine if the sound is indeed gunfire.

In the existing version of the system, police are quickly dispatched to the location. If they’re using ground transportation, however, it may take a while for them to get there. And even if the police department has a helicopter, performing pre-flight checks, etc will still take some time — assuming the aircraft isn’t already in the air on patrol, that is. With these potential limitations in mind, Israeli drone manufacturer Airobotics has teamed up with ShotSpotter to add autonomous drones to the mix. In the new version of the setup, police will still be dispatched, but so will the closest system-specific drone. That aircraft will be in the air within seconds, immediately flying to the source of the gunshots. By analyzing the live video from its onboard camera, police officers can then gain a better sense of the situation they’re heading into.
