Researchers at BitEnergy AI, Inc. have developed Linear-Complexity Multiplication (L-Mul), a technique that reduces AI model power consumption by up to 95% by replacing energy-intensive floating-point multiplications with simpler integer additions. This method promises significant energy savings without compromising accuracy, but it requires specialized hardware to fully realize its benefits. Decrypt reports: L-Mul tackles the AI energy problem head-on by reimagining how AI models handle calculations. Instead of complex floating-point multiplications, L-Mul approximates these operations using integer additions. So, for example, instead of multiplying 123.45 by 67.89, L-Mul breaks it down into smaller, easier steps using addition. This makes the calculations faster and uses less energy, while still maintaining accuracy. The results seem promising. "Applying the L-Mul operation in tensor processing hardware can potentially reduce 95% energy cost by element wise floating point tensor multiplications and 80% energy cost of dot products," the researchers claim. Without getting overly complicated, what that means is simply this: If a model used this technique, it would require 95% less energy to think, and 80% less energy to come up with new ideas, according to this research. The algorithm's impact extends beyond energy savings. L-Mul outperforms current 8-bit standards in some cases, achieving higher precision while using significantly less bit-level computation. Tests across natural language processing, vision tasks, and symbolic reasoning showed an average performance drop of just 0.07% -- a negligible tradeoff for the potential energy savings. Transformer-based models, the backbone of large language models like GPT, could benefit greatly from L-Mul. The algorithm seamlessly integrates into the attention mechanism, a computationally intensive part of these models. Tests on popular models such as Llama, Mistral, and Gemma even revealed some accuracy gain on certain vision tasks. At an operational level, L-Mul's advantages become even clearer. The research shows that multiplying two float8 numbers (the way AI models would operate today) requires 325 operations, while L-Mul uses only 157 -- less than half. "To summarize the error and complexity analysis, L-Mul is both more efficient and more accurate than fp8 multiplication," the study concludes. But nothing is perfect and this technique has a major achilles heel: It requires a special type of hardware, so the current hardware isn't optimized to take full advantage of it. Plans for specialized hardware that natively supports L-Mul calculations may be already in motion. "To unlock the full potential of our proposed method, we will implement the L-Mul and L-Matmul kernel algorithms on hardware level and develop programming APIs for high-level model design," the researchers say.

A new HBO documentary claims Canadian developer Peter Todd is Satoshi Nakamoto, the pseudonymous founder of bitcoin. The documentary's director, Emmy-nominated filmmaker Cullen Hoback, "comes to the conclusion by stitching together old clues and new ones," reports Politico. In the film's finale, Hoback confronted Todd and said: "It seems like you had these deep insights into bitcoin at the time?" Todd replies: "Well, yeah, I'm Satoshi Nakamoto." From the report: The admission, however, is not necessarily a smoking gun. Todd, who is a vocal backer of Ukraine and Israel on his X feed, is known to invoke the claim "I am Satoshi" as an expression of solidarity with the creator's bid for privacy. In an email to CoinDesk prior to the documentary's release, Todd reportedly denied he was the bitcoin creator: "Of course I'm not Satoshi," he said. If Todd is widely accepted as bitcoin's creator, the revelation would end more than a decade of speculation over the identity of a person whose work spawned a global, multibillion-dollar craze for digital currencies: a mania that has pushed back the frontiers of finance but also enabled widespread fraud and other illicit activities. Todd is not unknown to enthusiasts of the stateless money system. As a longstanding bitcoin core developer known for communicating publicly with "Satoshi" before his disappearance from crypto forums in 2010, his name has always carried weight in the community. But he was rarely considered a prime suspect. A 39-year-old graduate of Ontario College of Art and Design in Toronto, Todd would have been 23 when the famous bitcoin white paper that first laid out the vision for the decentralized money system was being completed. Todd previously told a podcast he was about 15 years old when he first started communicating with key crypto influencers, known as the cypherpunks. "In investigations like these, digital forensics can only take you so far; they're like a compass," Hoback told POLITICO before the documentary aired. "Real answers can only be found offline."

Foxconn has chosen Mexico for the site of the world's largest manufacturing facility for Nvidia's GB200 superchips. These chips are a "key component of the U.S. firm's next-generation Blackwell family computing platform," notes Reuters. From the report: "We're building the largest GB200 production facility on the planet," said Benjamin Ting, Foxconn senior vice president for the cloud enterprise solutions business group. Nvidia said in August that it had started shipping Blackwell samples to its partners and customers after tweaking its design, and expected several billion dollars in revenue from these chips in the fourth quarter. Ting said the partnership between his company and Nvidia was very important and everyone was asking for Nvidia's Blackwell platform. "The demand is awfully huge," Ting said at the company's annual tech day in Taipei, standing next to Nvidia's vice president for AI and robotics, Deepu Talla. Speaking to reporters later, Foxconn Chairman Young Liu said the plant was being built in Mexico, and that the capacity there would be "very, very enormous". He did not elaborate. Foxconn already has a large manufacturing presence in Mexico and has invested more than $500 million to date in the state of Chihuahua. Liu said the company's supply chain was ready for the AI revolution, adding its manufacturing capabilities include the "advanced liquid cooling and heat dissipation technologies necessary to complement the GB200 server's infrastructure."

"Alleged photos and videos of an unannounced 14-inch MacBook Pro with an M4 chip continue to surface on social media, in what could be the worst product leak for Apple since an employee accidentally left an iPhone 4 prototype at a bar in California in 2010," writes MacRumors' Joe Rossignol. From the report: The latest video of what could be a next-generation MacBook Pro was shared on YouTube Shorts today by Russian channel Romancev768, just one day after another Russian channel shared a similar video. The clip shows a box for a 14-inch MacBook Pro that is apparently configured with an M4 chip with a 10-core CPU and a 10-core GPU, 16GB of RAM, 512GB of storage, three Thunderbolt 4 ports, and a Space Black finish. According to the "About This Mac" software menu shown in the video, the MacBook Pro in the video is allegedly an unreleased November 2024 model. [...] Apple is well known for having a culture of secrecy, so this magnitude of leak is rarely seen for its products. As previously mentioned, this could be the most significant leak for Apple since Gizmodo obtained and shared photos of an iPhone 4 prototype that a then-employee of the company accidentally left behind at a bar in California. In that case, Apple got law enforcement involved, but how it acts this time around remains to be seen.

"Plasma is a popular desktop (and mobile) environment for GNU/Linux and other UNIX-like operating systems," writes longtime Slashdot reader jrepin. "Among other things, it also powers the desktop mode of the Steam Deck gaming handheld. The KDE community today announced the latest release, Plasma 6.2." From the report: Plasma 6.2 includes a smorgasbord of new features for users of drawing tablets. It implements more complete support for the Wayland color management protocol, and enables it by default. There is also improved brightness handling for HDR and ICC profiles, as well as HDR performance. A new tone mapping feature built into Plasma's KWin compositor will help improve the look of images with a brightness or set of colors greater than what the screen can display, thus reducing the "blown out" look such images can otherwise exhibit. You can now override misbehaving applications that block the system from going to sleep or locking the screen (and thus prevent saving power), and you can also adjust the brightness of each connected monitor machine separately. Plasma's built-in app store and software management tool, Discover, now supports PostmarketOS packages for your mobile devices, helps you write better reviews of apps, and presents apps' license information more accurately. In Plasma 6.2, we overhauled System Settings' Accessibility page and added colorblindness filters. They've also added support for the full "sticky keys" feature on Wayland. You can read more about what's new in the complete changelog.

An anonymous reader quotes a report from Ars Technica: Months ago, 13-year-old Willis "Blue Scuti" Gibson became the first person to "beat" NES Tetris, crashing the game after a 1,511-line, 157-level performance. Over the weekend, 16-year-old Michael "dogplayingtetris" Artiaga became the first to reach an even more impressive plateau in the game, looping past Level 255 and instantly rolling the game all the way back to the ultra-slow Level 0. It took Artiaga a bit over 80 minutes and a full 3,300 cleared lines to finally achieve the game's first near-mythical "rebirth" live in front of hundreds of Twitch viewers. And after a bit of celebration and recovery on the low levels, Artiaga managed to keep his rolled-over game going for another 40 minutes, finally topping out after a total of 4,216 lines and a record 29.4 million points. Artiaga's record does come with a small asterisk since he used a version of the game that was modified to avoid the crashes that stopped Blue Scuti's historic run. Still, NES Tetris' first-ever level rollover is a monumental achievement and a testament to just how far competitive classic Tetris has come in a short time.

X has been restored in Brazil after being shut down nationwide for over a month. According to court documents released today, X ultimately complied with all of Brazilian Supreme Court Justice Alexandre de Moraes' demands. "They included blocking certain accounts from the platform, paying outstanding fines and naming a legal representative in the country," reports NPR. "Failure to do the latter had triggered the suspension." From the report: Elon Musk's X was blocked blocked on Aug. 30 in the highly online country of 213 million people -- and one of X's biggest markets, with estimates of its user base ranging from 20 to 40 million. De Moraes ordered the shutdown after a monthslong dispute with Musk over free speech, far-right accounts and misinformation. Musk had disparaged de Moraes, calling him an authoritarian and a censor, even though his rulings, including X's suspension, were repeatedly upheld by his peers. Brazilian law requires foreign companies to have a local legal representative to receive notifications of court decisions and swiftly take any requisite action -- particularly, in X's case, the takedown of accounts. Conceicao was first named X's legal representative in April and resigned four months later. The company named her to the same job on Sep. 20, according to the public filing with the Sao Paulo commercial registry. In an apparent effort to shield Conceicao from potential violations by X -- and risking arrest -- a clause has been written into Conceicao's new representation agreement that she must follow Brazilian law and court decisions, and that any legal responsibility she assumes on X's behalf requires prior instruction from the company in writing, according to the company's filing. There is nothing illegal or suspect about using a company like BR4Business for legal representation, but it shows that X is doing the bare minimum to operate in the country, said Fabio de Sa e Silva, a lawyer and associate professor of International and Brazilian Studies at the University of Oklahoma. "It doesn't demonstrate an intention to truly engage with the country. Take Meta, for example, and Google. They have an office, a government relations department, precisely to interact with public authorities and discuss Brazil's regulatory policies concerning their businesses," Silva added. [...] "The concern now is what comes next and how X, once back in operation, will manage to meet the demands of the market and local authorities without creating new tensions," he said.

Investment firm Hindenburg Research claims Roblox is "consistently overstating the amount of people on its platform by 25 percent to 42 percent or more." The Verge reports: Roblox, which went public in 2021, reported having 79.5 million daily active users in its most recent earnings report. However, Hindenburg claims Roblox "intentionally conflates" actual people with daily users, as that number could also include alt accounts and bots. The research alleges that Roblox can separate alt accounts from single users, even though the company's disclosure says daily active users "are not a measure of unique individuals accessing Roblox." Hindenburg is an activist short-selling firm that infamously publishes research when it says it's identified something shady about a business, allowing it to make a profit as its share value declines. One example is from 2020, when Hindenburg accused the EV startup Nikola of fraud. Subsequently, an investigation by the Securities and Exchange Commission (SEC) resulted in a four-year prison sentence for its founder, Trevor Milton. [...] The firm also claims Roblox isn't doing enough to protect children on the platform, alleging its "in-game research revealed an X-rated pedophile hellscape, exposing children to grooming, pornography, violent content and extremely abusive speech." Roblox shares dipped following the release of the report. Desiree Fish, Roblox's chief communications officer, said in a statement: "We totally reject the claims made in the report. The financial claims made by Hindenburg Research are simply misleading. The authors are, admittedly short sellers and have an agenda irrespective of the substance of Roblox's business model and results. Over the past four quarters our bookings, the amount of cash receipts, have grown over 22% from $780.7 million in Q2 2023 to $955.2 million in Q2 2024. Over the same time, cash provided by operating activities have totaled $646.3 million, free cash flow was $440.3 million, and we have guided to even higher numbers for fiscal 2024. An examination of our GAAP balance sheet and our GAAP cash flow statement makes that clear. The focus on cash bookings and cash flow are themes that we have focused on consistently with investors dating back to our days as a private company. The author made no attempt to highlight any of that because the positive facts simply don't support their agenda."

An anonymous reader quotes a report from TechCrunch: U.S. money transfer giant MoneyGram has confirmed that hackers stole its customers' personal information and transaction data during a cyberattack last month. The company said in a statement Monday that an unauthorized third party "accessed and acquired" customer data during the cyberattack on September 20. The cyberattack -- the nature of which remains unknown -- sparked a week-long outage that resulted in the company's website and app falling offline. MoneyGram says it serves over 50 million people in more than 200 countries and territories each year. The stolen customer data includes names, phone numbers, postal and email addresses, dates of birth, and national identification numbers. The data also includes a "limited number" of Social Security numbers and government identification documents, such as driver's licenses and other documents that contain personal information, like utility bills and bank account numbers. MoneyGram said the types of stolen data will vary by individual. MoneyGram said that the stolen data also included transaction information, such as dates and amounts of transactions, and, "for a limited number of consumers, criminal investigation information (such as fraud)."

The District of Columbia and 13 states sued social media giant TikTok on Tuesday, accusing the company of knowingly creating an addictive product and getting children hooked with "digital nicotine." From a report: D.C. Attorney General Brian Schwalb brought Washington's suit in the Superior Court for the District of Columbia, asserting that the app's design -- including its algorithm, "infinite scroll," push notifications, filters and in-app currency -- boost the company's profits at the expense of children's health. "TikTok's platform, designed to be dangerously addictive, inflicts immense damage on an entire generation of young people," Schwalb said in a statement announcing the suit. "In addition to prioritizing its profits over the health of children, TikTok's unregulated and illegal virtual economy allows the darkest, most depraved corners of society to prey upon vulnerable victims." More than a dozen states brought similar suits against TikTok in their courts Tuesday, including New York, California, Kentucky and New Jersey. Each stems from a national investigation into the company that a bipartisan coalition of attorneys general launched in March 2022.

Veteran Microsoft engineer Larry Osterman is the latest to throw his hat into the "tabs versus spaces" ring. From a report: The debate has vexed engineers for decades -- is it best to indent code with tabs or spaces? Osterman, a four-decade veteran of Microsoft, was Team Tabs when storage was tight, but has since become Team Spaces with the advent of terabytes of relatively inexpensive storage. "Here's the thing," he said. "When you've got 512 kilobytes, and you're writing a program in Pascal with lots of indentation, if you're taking eight bytes for every one of those indentations, for eight spaces, you could save seven bytes in your program by using a tab character." It all added up, even when floppy disks were part of the equation. However, according to Osterman, things have changed. Storage is less of an issue, so why not use spaces? A cynic might wonder if that sort of attitude has led to the bloatware of today, where software requires ever-increasing amounts of storage in return for precious little extra functionality and a never-ending stream of patches. Any decent compiler should strip out any extraneous characters, assuming the code is indeed being compiled beforehand and not interpreted at run-time. For his part, Osterman is now a member of team spaces. "I like spaces simply because it always works and it's always consistent," he said.

A long-shot congressional challenger in Virginia is so determined to debate the Democratic incumbent one more time that he created an AI chatbot to stand in for the candidate in case he's a no-show. From a report: Less than a month from election day, the race for Virginia's 8th congressional district is all but decided. The sitting congressman in this deeply Democratic district, Don Beyer, won handily in 2022 with nearly three-quarters of the vote. Bentley Hensel, a software engineer for good government group CivicActions, who is running as an independent, said he was frustrated by what he said was Beyer's refusal to appear for additional debates since September. So he hatched a unique plan that will test the bounds of both propriety and technology: a debate with Beyer's artificial intelligence likeness. And the candidate has created the AI chatbot himself -- without Beyer's permission. Call it the modern-day equivalent of the empty chair on stage. DonBot, as the AI is playfully known, is being trained on Beyer's official websites, press releases, and data from the Federal Election Commission. The text-based AI is based on an API from OpenAI, the maker of ChatGPT. The bot is not intended to mislead anyone and is trained to provide accurate answers, said Hensel, who has raised roughly $17,000 in outside contributions and personal loans to his campaign, compared to Beyer's $1.5 million fund.

Samsung has issued a rare apology after saying it expected to post just $6.78 billion in operating profit for the most recent quarter, about $900 million short of analyst expectations. From a report: "We have caused concerns about our fundamental technological competitiveness and the future of the company due to our performance falling short of the market's expectations," reads the statement attributed to Samsung Vice Chairman Jun Young-hyun. "Many people are talking about Samsung's crisis. We, who are leading the business, are responsible for all of this." Bloomberg adds: In another filing, Korea's largest company confessed to delays in delivering a key type of chip used with Nvidia processors for training AI -- allowing SK Hynix to dominate the so-called high-bandwidth memory arena. Apart from lagging SK Hynix in HBM, it's also shown little progress against Taiwan Semiconductor Manufacturing Co. in the outsourced production of custom-made chips. Samsung warned about "inventory adjustments" by unspecified customers, as well as increasing competition from a legacy or less-advanced Chinese memory chipmaker.

800,000 tons of rock have been excavated from a South Dakota research facility — part of a multi-year process "to help answer some of physics' biggest questions," writes America's Energy Department. "The caverns they excavated will hold a massive particle detector and accompanying equipment." Along with partners from more than 35 countries, the Department of Energy's Office of Science is supporting the Deep Underground Neutrino Experiment at the Long-Baseline Neutrino Facility (LBNF-DUNE)... To study how neutrinos change type as they travel, LBNF-DUNE will be sending a stream of neutrinos from DOE's Fermilab National Accelerator Laboratory in Illinois [nearly 600 miles away] to South Dakota. At the beginning and end of the particles' journey, detectors will measure the types of neutrinos and antineutrinos. By comparing the rates of how both particles change type, scientists may find a difference that accounts for that ancient misalignment. There's also hope they'll detect neutrinos from supernovae explosions — and maybe even decaying protons LBNF-DUNE will use massive, seven-story tall detectors. Each detector will have 17,000 tons of liquid argon. That vast quantity of liquid maximizes the likelihood that scientists will detect as many neutrinos as possible. The far detector — the one in South Dakota — will be located about a mile underground. That distance places it in the right location compared to Fermilab and blocks the detector from other cosmic particles. "Just carrying out the excavation took three years," the announcement notes. ("The team had to dissemble the equipment, move it deep underground, and then reassemble it.) The 800,000 tons of rock were moved to the surface and then stored in a former mine. "Now that the excavation is complete, the LBNF-DUNE team is moving on to the next steps. Currently, they are installing the far detector in the Sanford Underground Research Facility. They anticipate finishing construction and starting to operate the detector in 2028. The team will then move on to installing the near detector at Fermilab. "The launch of LBNF/DUNE will be the beginning of a new era in understanding neutrinos and knowing more about our universe as a whole."

Long-time Slashdot reader Bismillah writes: Python New Zealand has gone through some rough times lately, with its then-treasurer stealing money from the society.. Things were looking really serious for a while, with Python NZ looking at being liquidated due to the theft of funds. However, there is a silver lining to the story, as the free and open source movement rallied behind Python NZ and got them out of a serious pickle. "Our friends at Linux Australia and at the Python Software Foundation went well above and beyond to support us, and save us," says Tom Eastman president of Python New Zealand, in an article from interest.co.nz. He also says he hopes the treasure is ordered by the court to pay restitution. (In the article the treasurer confirms that he's pleaded guilty to the theft, which took place between February 2019 and October 2023 — leaving Python NZ owing conference supplies around $55,000.) "We had $26 in the bank accounts," Eastman tells the site. The group now has new transparency and accountability measures...

Long-time Slashdot reader schwit1 shared this report from Australia's public broadcaster ABC: Ecovacs robot vacuums, which have been found to suffer from critical cybersecurity flaws, are collecting photos, videos and voice recordings — taken inside customers' houses — to train the company's AI models. The Chinese home robotics company, which sells a range of popular Deebot models in Australia, said its users are "willingly participating" in a product improvement program. When users opt into this program through the Ecovacs smartphone app, they are not told what data will be collected, only that it will "help us strengthen the improvement of product functions and attached quality". Users are instructed to click "above" to read the specifics, however there is no link available on that page. Ecovacs's privacy policy — available elsewhere in the app — allows for blanket collection of user data for research purposes, including: - The 2D or 3D map of the user's house generated by the device - Voice recordings from the device's microphone — Photos or videos recorded by the device's camera "It also states that voice recordings, videos and photos that are deleted via the app may continue to be held and used by Ecovacs..."

An anonymous reader shared this report from the Washington Post: Hundreds of Americans have been arrested after being connected to a crime by facial recognition software, a Washington Post investigation has found, but many never know it because police seldom disclose their use of the controversial technology... In fact, the records show that officers often obscured their reliance on the software in public-facing reports, saying that they identified suspects "through investigative means" or that a human source such as a witness or police officer made the initial identification... The Coral Springs Police Department in South Florida instructs officers not to reveal the use of facial recognition in written reports, according to operations deputy chief Ryan Gallagher. He said investigative techniques are exempt from Florida's public disclosure laws... The department would disclose the source of the investigative lead if it were asked in a criminal proceeding, Gallagher added.... Prosecutors are required to inform defendants about any information that would help prove their innocence, reduce their sentence or hurt the credibility of a witness testifying against them. When prosecutors fail to disclose such information — known as a "Brady violation" after the 1963 Supreme Court ruling that mandates it — the court can declare a mistrial, overturn a conviction or even sanction the prosecutor. No federal laws regulate facial recognition and courts do not agree whether AI identifications are subject to Brady rules. Some states and cities have begun mandating greater transparency around the technology, but even in these locations, the technology is either not being used that often or it's not being disclosed, according to interviews and public records requests... Over the past four years, the Miami Police Department ran 2,500 facial recognition searches in investigations that led to at least 186 arrests and more than 50 convictions. Among the arrestees, just 1 in 16 were told about the technology's use — less than 7 percent — according to a review by The Post of public reports and interviews with some arrestees and their lawyers. The police department said that in some of those cases the technology was used for purposes other than identification, such as finding a suspect's social media feeds, but did not indicate in how many of the cases that happened. Carlos J. Martinez, the county's chief public defender, said he had no idea how many of his Miami clients were identified with facial recognition until The Post presented him with a list. "One of the basic tenets of our justice system is due process, is knowing what evidence there is against you and being able to challenge the evidence that's against you," Martinez said. "When that's kept from you, that is an all-powerful government that can trample all over us." After reviewing The Post's findings, Miami police and local prosecutors announced plans to revise their policies to require clearer disclosure in every case involving facial recognition. The article points out that Miami's Assistant Police Chief actually told a congressional panel on law enforcement AI use that his department is "the first to be completely transparent about" the use of facial recognition. (When confronted with the Washington Post's findings, he "acknowledged that officers may not have always informed local prosecutors [and] said the department would give prosecutors all information on the use of facial recognition, in past and future cases". He told the Post that the department would "begin training officers to always disclose the use of facial recognition in incident reports." But he also said they would "leave it up to prosecutors to decide what to disclose to defendants."
