Huge Google Search Document Leak Reveals Inner Workings of Ranking Algorithm

Par : BeauHD
29 mai 2024 à 01:30
Danny Goodwin reports via Search Engine Land: A trove of leaked Google documents has given us an unprecedented look inside Google Search and revealed some of the most important elements Google uses to rank content. Thousands of documents, which appear to come from Google's internal Content API Warehouse, were released March 13 on Github by an automated bot called yoshi-code-bot. These documents were shared with Rand Fishkin, SparkToro co-founder, earlier this month. What's inside. Here's what we know about the internal documents, thanks to Fishkin and [Michael King, iPullRank CEO]: Current: The documentation indicates this information is accurate as of March. Ranking features: 2,596 modules are represented in the API documentation with 14,014 attributes. Weighting: The documents did not specify how any of the ranking features are weighted -- just that they exist. Twiddlers: These are re-ranking functions that "can adjust the information retrieval score of a document or change the ranking of a document," according to King. Demotions: Content can be demoted for a variety of reasons, such as: a link doesn't match the target site; SERP signals indicate user dissatisfaction; Product reviews; Location; Exact match domains; and/or Porn. Change history: Google apparently keeps a copy of every version of every page it has ever indexed. Meaning, Google can "remember" every change ever made to a page. However, Google only uses the last 20 changes of a URL when analyzing links. Other interesting findings. According to Google's internal documents: Freshness matters -- Google looks at dates in the byline (bylineDate), URL (syntacticDate) and on-page content (semanticDate). To determine whether a document is or isn't a core topic of the website, Google vectorizes pages and sites, then compares the page embeddings (siteRadius) to the site embeddings (siteFocusScore). Google stores domain registration information (RegistrationInfo). Page titles still matter. Google has a feature called titlematchScore that is believed to measure how well a page title matches a query. Google measures the average weighted font size of terms in documents (avgTermWeight) and anchor text. What does it all mean? According to King: "[Y]ou need to drive more successful clicks using a broader set of queries and earn more link diversity if you want to continue to rank. Conceptually, it makes sense because a very strong piece of content will do that. A focus on driving more qualified traffic to a better user experience will send signals to Google that your page deserves to rank." [...] Fishkin added: "If there was one universal piece of advice I had for marketers seeking to broadly improve their organic search rankings and traffic, it would be: 'Build a notable, popular, well-recognized brand in your space, outside of Google search.'"

Chromebooks Will Get Gemini and New Google AI Features

Par : BeauHD

Google is introducing the Gemini AI chatbot to Chromebook Plus models, enhancing features like text rewriting, image editing, and hands-free control. Here are a few of the top new features coming to ChromeOS, as summarized by Wired: The first notable feature is Help Me Write, which works in any text box. Select text in any text box and right-click -- you'll see a box next to the standard right-click context menu. You can ask Google's AI to rewrite the selected text, rephrase it in a specific way, or change the tone. I tried to use it on a few sentences in this story but did not like any of the suggestions it gave me, so your mileage may vary. Or maybe I'm a better writer than Google's AI. Who knows? Google's bringing the same generative AI wallpaper system you'll find in Android to ChromeOS. You can access this feature in ChromeOS's wallpaper settings and generate images based on specific parameters. Weirdly, you can create these when you're in a video-calling app too. You'll see a menu option next to the system tray whenever the microphone and video camera are being accessed -- tap on it and click "Create with AI" and you can generate an image for your video call's background. I'm not sure why I'd want a background of a "surreal bicycle made of flowers in pink and purple," but there you go. AI! Here's something a little more useful: Magic Editor in Google Photos. Yep, the same feature that debuted in Google's Pixel 8 smartphones is now available on Chromebook Plus laptops. In the Google Photos app, you can press Edit on a photo and you'll see the option for Magic Editor. (You'll need to download more editing tools to get started.) This feature lets you erase unwanted objects in your photos, move a subject to another area of the frame, and fill in the backgrounds of photos. I successfully erased a paint can in the background of a photo of my dog, and it worked pretty quickly. Then there's Gemini. It's available as a stand-alone app, and you can ask it to do pretty much anything. Write a cover letter, break down complex topics, ask for travel tips for a specific country. Just, you know, double-check the results and make sure there aren't any hallucinations. If you want to tap into Google's Gemini Advanced model, the company says it is offering 12 months free for new Chromebook Plus owners through the end of the year, so you have some time to redeem that offer. This is technically an upgrade from Google One, and it nets you Gemini for Workspace, 2 terabytes of storage, and a few other perks. New features coming to all Chromebooks include easy setup with Android phones via QR code for sharing Wi-Fi credentials, integration of Google Tasks into the system tray, a Game Dashboard for mapping controls and recording gameplay as GIFs, and a built-in screen recorder tool. Upcoming enhancements also include Hands-Free Control using face gestures, the Help Me Read feature with Gemini for summarizing websites and PDFs, and an Overview screen to manage open browser windows, tabs, and apps. You can check if your Chromebook is compatible with the Chromebook Plus OS update here.

Instead of 'Auth,' We Should Say 'Permissions' and 'Login'

Par : BeauHD
29 mai 2024 à 00:10
The term "auth" is ambiguous, often meaning either authentication (authn) or authorization (authz), which leads to confusion and poor system design. Instead, Nicole Tietz-Sokolskaya, a software engineer at AI market research platform Remesh, argues that the industry adopt the terms "login" for authentication and "permissions" for authorization, as these are clearer and help maintain distinct, appropriate abstractions for each concept. From their blog post: We should always use the most clear terms we have. Sometimes there's not a great option, but here, we have wonderfully clear terms. Those are "login" for authentication and "permissions" for authorization. Both are terms that will make sense with little explanation (in contrast to "authn" and "authz", which are confusing on first encounter) since almost everyone has logged into a system and has run into permissions issues. There are two ways to use "login" here: the noun and the verb form. The noun form is "login", which refers to the information you enter to gain access to the system. And the verb form is "log in", which refers to the action of entering your login to use the system. "Permissions" is just the noun form. To use a verb, you would use "check permissions." While this is long, it's also just... fine? It hasn't been an issue in my experience. Both of these are abundantly clear even to our peers in disciplines outside software engineering. This to me makes it worth using them from a clarity perspective alone. But then we have the big benefit to abstractions, as well. When we call both by the same word, there's often an urge to combine them into a single module just by dint of the terminology. This isn't necessarily wrong -- there is certainly some merit to put them together, since permissions typically require a login. But it's not necessary, either, and our designs will be stronger if we don't make that assumption and instead make a reasoned choice.

Nvidia Denies Pirate e-Book Sites Are 'Shadow Libraries' To Shut Down Lawsuit

Par : BeauHD
28 mai 2024 à 23:30
An anonymous reader quotes a report from Ars Technica: Some of the most infamous so-called shadow libraries have increasingly faced legal pressure to either stop pirating books or risk being shut down or driven to the dark web. Among the biggest targets are Z-Library, which the US Department of Justice has charged with criminal copyright infringement, and Library Genesis (Libgen), which was sued by textbook publishers last fall for allegedly distributing digital copies of copyrighted works "on a massive scale in willful violation" of copyright laws. But now these shadow libraries and others accused of spurning copyrights have seemingly found an unlikely defender in Nvidia, the AI chipmaker among those profiting most from the recent AI boom. Nvidia seemed to defend the shadow libraries as a valid source of information online when responding to a lawsuit from book authors over the list of data repositories that were scraped to create the Books3 dataset used to train Nvidia's AI platform NeMo. That list includes some of the most "notorious" shadow libraries -- Bibliotik, Z-Library (Z-Lib), Libgen, Sci-Hub, and Anna's Archive, authors argued. However, Nvidia hopes to invalidate authors' copyright claims partly by denying that any of these controversial websites should even be considered shadow libraries. "Nvidia denies the characterization of the listed data repositories as 'shadow libraries' and denies that hosting data in or distributing data from the data repositories necessarily violates the US Copyright Act," Nvidia's court filing said. The chipmaker did not go into further detail to define what counts as a shadow library or what potentially absolves these controversial sites from key copyright concerns raised by various ongoing lawsuits. Instead, Nvidia kept its response brief while also curtly disputing authors' petition for class-action status and defending its AI training methods as fair use. "Nvidia denies that it has improperly used or copied the alleged works," the court filing said, arguing that "training is a highly transformative process that may include adjusting numerical parameters including 'weights,' and that outputs of an LLM may be based, at least in part, on such 'weights.'" "Nvidia's argument likely depends on the court agreeing that AI models ingesting published works in order to transform those works into weights governing AI outputs is fair use," notes Ars. "However, authors have argued that 'these weights are entirely and uniquely derived from the protected expression in the training dataset' that has been copied without getting authors' consent or providing authors with compensation." "Authors suing Nvidia have taken the next step, linking the chipmaker to shadow libraries by arguing that 'these shadow libraries have long been of interest to the AI-training community because they host and distribute vast quantities of unlicensed copyrighted material. For that reason, these shadow libraries also violate the US Copyright Act.'"

Internet Archive and the Wayback Machine Under DDoS Cyberattack

Par : BeauHD
28 mai 2024 à 22:50
The Internet Archive is "currently in its third day of warding off an intermittent DDoS cyber-attack," writes Chris Freeland, Director of Library Services at Internet Archive, in a blog post. While library staff stress that the archives are safe, access to its services are affected, including the Wayback Machine. From the post: Since the attacks began on Sunday, the DDoS intrusion has been launching tens of thousands of fake information requests per second. The source of the attack is unknown. "Thankfully the collections are safe, but we are sorry that the denial-of-service attack has knocked us offline intermittently during these last three days," explained Brewster Kahle, founder and digital librarian of the Internet Archive. "With the support from others and the hard work of staff we are hardening our defenses to provide more reliable access to our library. What is new is this attack has been sustained, impactful, targeted, adaptive, and importantly, mean." Cyber-attacks are increasingly frequent against libraries and other knowledge institutions, with the British Library, the Solano County Public Library (California), the Berlin Natural History Museum, and Ontario's London Public Library all being recent victims. In addition to a wave of recent cyber-attacks, the Internet Archive is also being sued by the US book publishing and US recording industries associations, which are claiming copyright infringement and demanding combined damages of hundreds of millions of dollars and diminished services from all libraries. "If our patrons around the globe think this latest situation is upsetting, then they should be very worried about what the publishing and recording industries have in mind," added Kahle. "I think they are trying to destroy this library entirely and hobble all libraries everywhere. But just as we're resisting the DDoS attack, we appreciate all the support in pushing back on this unjust litigation against our library and others."

Anthropic Hires Former OpenAI Safety Lead To Head Up New Team

Par : BeauHD
28 mai 2024 à 22:10
Jan Leike, one of OpenAI's "superalignment" leaders, who resigned last week due to AI safety concerns, has joined Anthropic to continue the mission. According to Leike, the new team "will work on scalable oversight, weak-to-strong generalization, and automated alignment research." TechCrunch reports: A source familiar with the matter tells TechCrunch that Leike will report directly to Jared Kaplan, Anthropic's chief science officer, and that Anthropic researchers currently working on scalable oversight -- techniques to control large-scale AI's behavior in predictable and desirable ways -- will move to report to Leike as Leike's team spins up. In many ways, Leike's team sounds similar in mission to OpenAI's recently-dissolved Superalignment team. The Superalignment team, which Leike co-led, had the ambitious goal of solving the core technical challenges of controlling superintelligent AI in the next four years, but often found itself hamstrung by OpenAI's leadership. Anthropic has often attempted to position itself as more safety-focused than OpenAI.

Researchers Cracked an 11-Year-Old Password To a $3 Million Software-Based Crypto Wallet

Par : BeauHD
28 mai 2024 à 21:30
An anonymous reader quotes a report from Wired: Two years ago when "Michael," an owner of cryptocurrency, contacted Joe Grand to help recover access to about $2 million worth of bitcoin he stored in encrypted format on his computer, Grand turned him down. Michael, who is based in Europe and asked to remain anonymous, stored the cryptocurrency in a password-protected digital wallet. He generated a password using the RoboForm password manager and stored that password in a file encrypted with a tool called TrueCrypt. At some point, that file got corrupted and Michael lost access to the 20-character password he had generated to secure his 43.6 BTC (worth a total of about [...] $5,300, in 2013). Michael used the RoboForm password manager to generate the password but did not store it in his manager. He worried that someone would hack his computer and obtain the password. "At [that] time, I was really paranoid with my security," he laughs. Grand is a famed hardware hacker who in 2022 helped another crypto wallet owner recover access to $2 million in cryptocurrencyhe thought he'd lost forever after forgetting the PIN to his Trezor wallet. Since then, dozens of people have contacted Grand to help them recover their treasure. But Grand, known by the hacker handle "Kingpin," turns down most of them, for various reasons. Grand is an electrical engineer who began hacking computing hardware at age 10 and in 2008 cohosted the Discovery Channel's Prototype This show. He now consults with companies that build complex digital systems to help them understand how hardware hackers like him might subvert their systems. He cracked the Trezor wallet in 2022 using complex hardware techniques that forced the USB-style wallet to reveal its password. But Michael stored his cryptocurrency in a software-based wallet, which meant none of Grand's hardware skills were relevant this time. [...] Michael contacted multiple people who specialize in cracking cryptography; they all told him "there's no chance" of retrieving his money. But last June he approached Grand again, hoping to convince him to help, and this time Grand agreed to give it a try, working with a friend named Bruno in Germany who also hacks digital wallets. Grand and Bruno spent months reverse engineering the version of the RoboForm program that they thought Michael had used in 2013 and found that the pseudo-random number generator used to generate passwords in that version -- and subsequent versions until 2015 -- did indeed have a significant flaw that made the random number generator not so random. The RoboForm program unwisely tied the random passwords it generated to the date and time on the user's computer -- it determined the computer's date and time, and then generated passwords that were predictable. If you knew the date and time and other parameters, you could compute any password that would have been generated on a certain date and time in the past. [...] There was one problem: Michael couldn't remember when he created the password. According to the log on his software wallet, Michael moved bitcoin into his wallet for the first time on April 14, 2013. But he couldn't remember if he generated the password the same day or some time before or after this. So, looking at the parameters of other passwords he generated using RoboForm, Grand and Bruno configured RoboForm to generate 20-character passwords with upper- and lower-case letters, numbers, and eight special characters from March 1 to April 20, 2013. It failed to generate the right password. [...] Instead, they revealed that they had finally found the correct password -- no special characters. It was generated on May 15, 2013, at 4:10:40 pm GMT.

New Warp Drive Concept Does Twist Space, Doesn't Move Us Very Fast

Par : BeauHD
25 mai 2024 à 13:00
An anonymous reader quotes a report from Ars Technica: A team of physicists has discovered that it's possible to build a real, actual, physical warp drive and not break any known rules of physics. One caveat: the vessel doing the warping can't exceed the speed of light, so you're not going to get anywhere interesting any time soon. But this research still represents an important advance in our understanding of gravity. [...] In a paper accepted for publication in the journal Classical and Quantum Gravity, [an international team of physicists led by Jared Fuchs at the University of Alabama in Huntsville] dug deep into relativity to explore if any version of a warp drive could work. The equations of general relativity are notoriously difficult to solve, especially in complex cases such as a warp drive. So the team turned to software algorithms; instead of trying to solve the equations by hand, they explored their solutions numerically and verified that they conformed to the energy conditions. The team did not actually attempt to construct a propulsion device. Instead, they explored various solutions to general relativity that would allow travel from point to point without a vessel undergoing any acceleration or experiencing any overwhelming gravitational tidal forces within the vessel, much to the comfort of any imagined passengers. They then checked whether these solutions adhered to the energy conditions that prevent the use of exotic matter. The researchers did indeed discover a warp drive solution: a method of manipulating space so that travelers can move without accelerating. There is no such thing as a free lunch, however, and the physicality of this warp drive does come with a major caveat: the vessel and passengers can never travel faster than light. Also disappointing: the fact that the researchers behind the new work don't seem to bother with figuring out what configurations of matter would allow the warping to happen. The findings have been published in the journal Classical and Quantum Gravity.

China's Blistering Solar Growth Runs Into Grid Blocks

Par : BeauHD
25 mai 2024 à 10:00
China's rapid solar power expansion is slowing due to grid bottlenecks, market reforms, and diminishing rooftop space, with new solar builds dropping 32% in March year-on-year. Reuters reports: The country's solar power expansion is slowing due to tighter curbs on supplying excess power from rooftop solar into the grid and changes in electricity pricing that are denting the economics of new solar projects. Forecasts show China's solar build this year will be heavily outpaced by growth in its photovoltaic (PV) module manufacturing capacity, raising the prospect the country will export more solar panels despite a trade backlash in Europe and the U.S. The main factor slowing the expansion of distributed solar - installations built near the point of use, mostly on rooftops - is that there is not enough storage or transmission capacity to soak up the excess power generated when the sun is shining. That in turn is leading regulators to take away some of the price support that led to the rapid growth of distributed solar. "In the next couple of years, this is going to be a huge problem that all provinces will face as grids are oversaturated, the infrastructure is overwhelmed," said Cosimo Ries, an analyst with Trivium China, a policy research group. [...] Renewable generators previously enjoyed a guarantee that grid operators would buy nearly all of their power at a rate tied to the coal index. That guarantee was lifted on April 1 and took effect earlier in some places, three industry experts said. Now, renewable generation is increasingly subject to less favourable market pricing. Shenhua Energy, a state-run coal and power firm, said in its first-quarter report that prices for its solar power fell 34.2% year-on-year to 283 yuan per megawatt-hour (MWh), while its coal power prices fell just 2.4% to 406 yuan per MWh. Wang Xiuqiang, a researcher at consultancy Beijing Linghang, attributed the lower solar prices and profitability to a higher proportion of market-based pricing. At the same time, grid companies are dialling back the 5% curtailment limit, "creating the risk for project owners that their generation might not be bought", said David Fishman of Shanghai-based energy consultancy the Lantau Group. Curtailment for Huaneng Power International, a major state-owned generator, rose to 7.7% in the first quarter from 3.1% a year earlier, Jefferies analysts said in a client note, citing Huaneng management. In a further challenge, the easiest-to-site projects have already been largely developed, said Shi Lida, research manager at Yongan Guofu Asset Management. At sites still available, rooftops may need to be reinforced, grid connections may be limited, or hours of sunlight may be short. "If your costs don't continue to fall, the investment will not be cost effective," Shi said. Further reading: Germany Has Too Many Solar Panels, and It's Pushed Energy Prices Negative

Eagles Changed Migration Route To Avoid Ukraine War

Par : BeauHD
25 mai 2024 à 07:00
Scientists report that Greater Spotted Eagles altered their migration routes across Ukraine to avoid conflict and habitat destruction caused by the war. The BBC reports: The scientists studied GPS data from tagged birds in the months after the February 2022 invasion, a time of heavy fighting in northern Ukraine as Russia tried to take Kyiv by sending troops south from Belarus. The researchers from the Estonian University of Life Sciences and the British Trust for Ornithology reported their findings in the journal Current Biology. "The war in Ukraine has had a devastating impact on people and the environment. Our findings provide a rare window into how conflicts affect wildlife," said lead author Charlie Russell, a postgraduate researcher at the University of East Anglia. Classified as a vulnerable species, the Greater Spotted Eagle is a large, brownish-colored bird of prey. Researchers started following them using GPS tracking devices in 2017 but didn't expect to be monitoring them through an active conflict zone five years later. The findings reveal they made large deviations from their previously tracked routes. They also spent less time stopping at their usual refueling sites in Ukraine or avoided them entirely. As a result, they traveled farther, about an extra 52 miles (85km) on average. For migrating birds, stopover sites are essential places to get food, water, and shelter. These changes delayed the birds' arrival at the breeding grounds and likely made them use more energy, to damaging effect. "No doubt about it. I think the take-home story is that the conflict in Ukraine is fundamentally disrupting the migratory ecology of this species," said Dr Jim Reynolds, Assistant Professor in Ornithology and Animal Conservation at the University of Birmingham, who was independent from the study. "For a vulnerable species like this, anything that disrupts breeding performance is a major problem. As a conservation biologist, you worry about that in a massive way." Despite all the tagged birds surviving, researchers believe their experience may have affected their ability to breed.

Best Buy and Geek Squad Were Most Impersonated Orgs By Scammers In 2023

Par : BeauHD
25 mai 2024 à 03:30
An anonymous reader quotes a report from The Register: The Federal Trade Commission (FTC) has shared data on the most impersonated companies in 2023, which include Best Buy, Amazon, and PayPal in the top three. The federal agency detailed the top ten companies scammers impersonate and how much they make depending on the impersonation. By far the most impersonated corp was Best Buy and its repair business Geek Squad, with a total of 52k reports. Amazon impersonators came in second place with 34k reports, and PayPal a distant third with 10,000. Proportionally, the top three made up roughly 72 percent of the reports among the top ten, and Best Buy and Geek Squad scam reports were about 39 percent on their own. Though, high quantity doesn't necessarily translate to greater success for scammers, as the FTC also showed how much scammers made depending on what companies they impersonated. Best Buy and Geek Squad, Amazon, and PayPal scams made about $15 million, $19 million, and $16 million respectively, but that's nothing compared to the $60 million that Microsoft impersonators were able to fleece. [...] The FTC also reported the vectors scammers use to contact their victims. Phone and email are still the most common means, but social media is becoming increasingly important for scamming and features the most costly scams. The feds additionally disclosed the kinds of payment methods scammers use for all sorts of frauds, including company and individual impersonation scams, investment scams, and romance scams. Cryptocurrency and bank transfers were popular for investment scammers, who are the most prolific on social media, while gift cards were most common for pretty much every other type of scam. However, not all scammers ask for digital payment, as the Federal Bureau of Investigation says that even regular old mail is something scammers are relying on to get their ill-gotten gains.

Feds Add Nine More Incidents To Waymo Robotaxi Investigation

Par : BeauHD
25 mai 2024 à 01:25
Nine more accidents have been discovered by federal safety regulators during their safety investigation of Waymo's self-driving vehicles in Phoenix and San Francisco. TechCrunch reports: The National Highway Traffic Safety Administration Office of Defects Investigation (ODI) opened an investigation earlier this month into Waymo's autonomous vehicle software after receiving 22 reports of robotaxis making unexpected moves that led to crashes and potentially violated traffic safety laws. The investigation, which has been designated a "preliminary evaluation," is examining the software and its ability to avoid collisions with stationary objects and how well it detects and responds to "traffic safety control devices" like cones. The agency said Friday it has added (PDF) another nine incidents since the investigation was opened. Waymo reported some of these incidents. The others were discovered by regulators via public postings on social media and forums like Reddit, YouTube and X. The additional nine incidents include reports of Waymo robotaxis colliding with gates, utility poles, and parked vehicles, driving in the wrong lane with nearby oncoming traffic and into construction zones. The ODI said it's concerned the robotaxis "exhibiting such unexpected driving behaviors may increase the risk of crash, property damage, and injury." The agency said that while it's not aware of any injuries from these incidents, several involved collisions with visible objects that "a competent driver would be expected to avoid." The agency also expressed concern that some of these occurred near pedestrians. NHTSA has given Waymo until June 11 to respond to a series of questions regarding the investigation.

Google Threatens To Pause Google News Initiative Funding In US

Par : BeauHD
25 mai 2024 à 00:45
Google has warned nonprofit newsrooms that a new California bill taxing Big Tech for digital ad transactions would jeopardize future investments in the U.S. news industry. "This is the second time this year Google has threatened to pull investment in news in response to a regulatory threat in California -- but this time, hundreds of publishers outside of California would also feel the impact," reports Axios. From the report: Google's new outreach to smaller news outlets is happening in response to a different bill, introduced this year by State Sen. Steve Glazer, that would tax Big Tech companies like Google and Meta for "data extraction transactions," or digital ad transactions. Tax revenue would fund tax credits meant to support the hiring of more journalists in California by eligible nonprofit local news organizations. With the link tax bill, Google only threatened to pull news investments in California. But the company is telling partners that the ad tax proposal will threaten consideration of new grants nationwide by the Google News Initiative, which funds hundreds of smaller news outlets, sources told Axios. Previous commitments, however, should be secure. A spokesperson for the Institute for Nonprofit News said the organization believes that grants previously committed through GNI as described here "are secure, so INN members should continue to benefit through this particular Fundamentals Labs program." Google's concern, sources familiar with the company's thinking told Axios, is that the new California ad tax bill could set a troubling wider precedent for other states. California's Senate tax committee approved the "ad tax" bill May 8. Days after that, Google started making calls to nonprofits about potentially pausing future Google News Initiative funding, sources told Axios. Opponents argue (PDF) the ad tax burden would get passed down to consumers and businesses. They also say the measure would face legal challenges, similar to a digital ad tax introduced in Maryland last year.

FTC Chair: AI Models Could Violate Antitrust Laws

Par : BeauHD
25 mai 2024 à 00:02
An anonymous reader quotes a report from The Hill: Federal Trade Commission (FTC) Chair Lina Khan said Wednesday that companies that train their artificial intelligence (A) models on data from news websites, artists' creations or people's personal information could be in violation of antitrust laws. At The Wall Street Journal's "Future of Everything Festival," Khan said the FTC is examining ways in which major companies' data scraping could hinder competition or potentially violate people's privacy rights. "The FTC Act prohibits unfair methods of competition and unfair or deceptive acts or practices," Khan said at the event. "So, you can imagine, if somebody's content or information is being scraped that they have produced, and then is being used in ways to compete with them and to dislodge them from the market and divert businesses, in some cases, that could be an unfair method of competition." Khan said concern also lies in companies using people's data without their knowledge or consent, which can also raise legal concerns. "We've also seen a lot of concern about deception, about unfairness, if firms are making one set of representations when you're signing up to use them, but then are secretly or quietly using the data you're feeding them -- be it your personal data, be it, if you're a business, your proprietary data, your competitively significant data -- if they're then using that to feed their models, to compete with you, to abuse your privacy, that can also raise legal concerns," she said. Khan also recognized people's concerns about companies retroactively changing their terms of service to let them use customers' content, including personal photos or family videos, to feed into their AI models. "I think that's where people feel a sense of violation, that that's not really what they signed up for and oftentimes, they feel that they don't have recourse," Khan said. "Some of these services are essential for navigating day to day life," she continued, "and so, if the choice -- 'choice' -- you're being presented with is: sign off on not just being endlessly surveilled, but all of that data being fed into these models, or forego using these services entirely, I think that's a really tough spot to put people in." Khan said she thinks many government agencies have an important role to play as AI continues to develop, saying, "I think in Washington, there's increasingly a recognition that we can't, as a government, just be totally hands off and stand out of the way."

UK Law Will Let Regulators Fine Big Tech Without Court Approval

Par : BeauHD
24 mai 2024 à 23:20
Emma Roth reports via The Verge: The UK could subject big tech companies to hefty fines if they don't comply with new rules meant to promote competition in digital markets. On Thursday, lawmakers passed the Digital Markets, Competition and Consumer Bill (DMCC) through Parliament, which will let regulators enforce rules without the help of the courts. The DMCC also addresses consumer protection issues by banning fake reviews, forcing companies to be more transparent about their subscription contracts, regulating secondary ticket sales, and getting rid of hidden fees. It will also force certain companies to report mergers to the UK's Competition and Markets Authority (CMA). The European Union enacted a similar law, called the Digital Markets Act (DMA). Only the companies the CMA designates as having Strategic Market Status (SMS) have to comply. These SMS companies are described as having "substantial and entrenched market power" and "a position of strategic significance" in the UK. They must have a global revenue of more than 25 billion euros or UK revenue of more than 1 billion euros. The law will also give the CMA the authority to determine whether a company has broken a law, require compliance, and issue a fine -- all without going through the court system. The CMA can fine companies up to 10 percent of the total value of a business's global revenue for violating the new rules.

OpenAI has reversed its decision requiring former employees to sign a perpetual non-disparagement agreement to retain their vested equity, stating that they will not cancel any vested units and will remove non-disparagement clauses from departure documents. CNBC reports: The internal memo, which was viewed by CNBC, was sent to former employees and shared with current ones. The memo, addressed to each former employee, said that at the time of the person's departure from OpenAI, "you may have been informed that you were required to execute a general release agreement that included a non-disparagement provision in order to retain the Vested Units [of equity]." "Regardless of whether you executed the Agreement, we write to notify you that OpenAI has not canceled, and will not cancel, any Vested Units," stated the memo, which was viewed by CNBC. The memo said OpenAI will also not enforce any other non-disparagement or non-solicitation contract items that the employee may have signed. "As we shared with employees, we are making important updates to our departure process," an OpenAI spokesperson told CNBC in a statement. "We have not and never will take away vested equity, even when people didn't sign the departure documents. We'll remove non-disparagement clauses from our standard departure paperwork, and we'll release former employees from existing non-disparagement obligations unless the non-disparagement provision was mutual," said the statement, adding that former employees would be informed of this as well. "We're incredibly sorry that we're only changing this language now; it doesn't reflect our values or the company we want to be," the OpenAI spokesperson added.

Google Search's 'udm=14' Trick Lets You Kill AI Search For Good

An anonymous reader quotes a report from Ars Technica: If you're tired of Google's AI Overview extracting all value from the web while also telling people to eat glue or run with scissors, you can turn it off -- sort of. Google has been telling people its AI box at the top of search results is the future, and you can't turn it off, but that ignores how Google search works: A lot of options are powered by URL parameters. That means you can turn off AI search with this one simple trick! (Sorry.) Our method for killing AI search is defaulting to the new "web" search filter, which Google recently launched as a way to search the web without Google's alpha-quality AI junk. It's actually pretty nice, showing only the traditional 10 blue links, giving you a clean (well, other than the ads), uncluttered results page that looks like it's from 2011. Sadly, Google's UI doesn't have a way to make "web" search the default, and switching to it means digging through the "more" options drop-down after you do a search, so it's a few clicks deep. Check out the URL after you do a search, and you'll see a mile-long URL full of esoteric tracking information and mode information. We'll put each search result URL parameter on a new line so the URL is somewhat readable [...]. Most of these only mean something to Google's internal tracking system, but that "&udm=14" line is the one that will put you in a web search. Tack it on to the end of a normal search, and you'll be booted into the clean 10 blue links interface. While Google might not let you set this as a default, if you have a way to automatically edit the Google search URL, you can create your own defaults. One way to edit the search URL is a proxy site like udm14.com, which is probably the biggest site out there popularizing this technique. A proxy site could, if it wanted to, read all your search result queries, though (your query is also in the URL), so whether you trust this site is up to you.

Crows Can 'Count' Out Loud, Study Shows

An anonymous reader quotes a report from ScienceAlert: A team of scientists has shown that crows can 'count' out loud -- producing a specific and deliberate number of caws in response to visual and auditory cues. While other animals such as honeybees have shown an ability to understand numbers, this specific manifestation of numeric literacy has not yet been observed in any other non-human species. "Producing a specific number of vocalizations with purpose requires a sophisticated combination of numerical abilities and vocal control," writes the team of researchers led by neuroscientist Diana Liao of the University of Tubingen in Germany. "Whether this capacity exists in animals other than humans is yet unknown. We show that crows can flexibly produce variable numbers of one to four vocalizations in response to arbitrary cues associated with numerical values." The ability to count aloud is distinct from understanding numbers. It requires not only that understanding, but purposeful vocal control with the aim of communication. Humans are known to use speech to count numbers and communicate quantities, an ability taught young. [...] "Our results demonstrate that crows can flexibly and deliberately produce an instructed number of vocalizations by using the 'approximate number system', a non-symbolic number estimation system shared by humans and animals," the researchers write in their paper. "This competency in crows also mirrors toddlers' enumeration skills before they learn to understand cardinal number words and may therefore constitute an evolutionary precursor of true counting where numbers are part of a combinatorial symbol system." The findings have been published in the journal Science.

Euclid Telescope Spies Rogue Planets Floating Free In Milky Way

Using the Euclid space telescope, astronomers have discovered dozens of rogue planets drifting without stars in the Orion nebula. The Guardian reports: The European Space Agency (Esa) launched the $1 billion observatory last summer on a six-year mission to create a 3D map of the cosmos. Armed with its images, scientists hope to understand more about the mysterious 95% of the universe that is unexplained. The first wave of scientific results come from only 24 hours of observations, which revealed 11m objects in visible light and 5m in infrared. Along with the rogue planets, the researchers describe new star clusters, dwarf galaxies and very distant, bright galaxies from the first billion years of the universe. A flurry of new images from the same observations are the largest ever taken in space and demonstrate the stunning wide-field views that astronomers can expect from Euclid in the coming years. Among those released on Thursday is a breathtaking image of Messier 78, a vibrant star nursery shrouded in interstellar dust, that reveals complex filaments of gas and dust in unprecedented detail. One of the newly released images shows Abell 2390, a giant conglomeration of more than 50,000 Milky Way-like galaxies. Such galaxy clusters contain up to 10 trillion times as much mass as the sun, much of which is believed to be elusive dark matter. Another image of the Abell 2764 galaxy cluster reveals hundreds of galaxies orbiting within a halo of dark matter. Other images capture NGC 6744, one of the largest spiral galaxies in the nearby universe, and the Dorado group of galaxies, where evolving and merging galaxies produce shell-like structures and vast, curving tidal tails. The rogue planets spotted by Euclid are about 3m years old, making them youngsters on the cosmic scale. They are at least four times as big as Jupiter and were detected thanks to the warmth they emit. Astronomers know they are free-floating because they are so far away from the nearest stars. The celestial strays are destined to drift through the galaxy unless they encounter a star that pulls them into orbit.
