"A new study released Friday found that young children diagnosed with attention-deficit/hyperactivity disorder, or ADHD, are often prescribed medication too quickly," reports CBS News: The study, led by Stanford Medicine and published in JAMA Network Open, examined the health records of nearly 10,000 preschool-aged children ages 3 to 5 between 2016 and 2023 who were diagnosed with ADHD... The Stanford study found that about 68% of those children who were diagnosed with ADHD were prescribed medications before age 7, most often stimulants such as Ritalin, which can help children focus their attention and regulate their emotions. The turn to medication often came quickly, according to the study. About 42% of the children who were diagnosed with ADHD were prescribed drugs within 30 days of diagnosis, the study found. "We don't have concerns about the toxicity of the medications for 4- and 5-year-olds, but we do know that there is a high likelihood of treatment failure, because many families decide the side effects outweigh the benefits," Dr. Yair Bannett, assistant professor of pediatrics at Stanford Medicine and the lead author of the study, said in a statement. Those side effects can include irritability, aggressiveness and emotional problems, according to Bannett. "The high rate of medication prescriptions among preschool-age children with ADHD and the lack of delay between initial diagnosis and prescription require further investigation to assess the appropriateness of early medication treatment," the researchers concluded. The study also found that the vast majority of the young children diagnosed with ADHD, about 76%, were boys. CBS News interviewed Jamie Howard, senior clinical psychologist from the Child Mind Institute (who was not involved in the study). Howard said when treating ADHD in young children, clinical guidelines call for starting with "behavioral intervention...." "I think that people have an association with ADHD and stimulant medication... But there is actually a lot more than that. And we want to give kids the opportunity to use these other strategies first, and then if they need medication, it can be incredibly helpful for a lot of kids."

The Washington Post covers "a string of false reports of active shooters at a dozen U.S. universities this month as students returned to campus." The FBI is investigating the incidents, according to a spokesperson who declined to specify the nature of the probe. While universities have proved a popular swatting target, the agency "is seeing an increase in swatting events across the country," the FBI spokesperson said... Local officials are frustrated by the anonymous calls tying up first responders, straining public safety budgets and needlessly traumatizing college students who grew up in an era in which gun violence has in some way shaped their school experience... The recent string of swattings began Thursday with a false report to the University of Tennessee at Chattanooga, quickly followed by one about Villanova University later that day. Hoaxes at 10 more schools followed... Villanova also received a second threat. As the calls about shootings came in, officials on many of the campuses pushed out emergency notifications directing students and employees to shelter in place, while police investigated what turned out to be false reports. (Iowa State was able to verify the lack of a threat before a campuswide alert was sent, its police chief said. [They had a live video feed from the location the caller claimed to be from.]) In at least three cases, 911 calls reporting a shooting purported to come from campus libraries, where the sound of gunshots could be heard over the phone, officials told The Washington Post... Although false bomb reports, shooter threats and swatting incidents are not new, bad actors used to be more easily traceable through landline phones. But the era of internet-based services, virtual private networks, and anonymous text and chat tools has made unmasking hoax callers far more challenging... In 2023, a Post investigation found that more than 500 schools across the United States were subject to a coordinated swatting effort that may have had origins abroad... [In Chattanooga, Tennessee last week] a dispatcher heard gunfire during a call reporting an on-campus shooting. "We grabbed everybody that wasn't already out on the street and got to that location," said University of Tennessee at Chattanooga Police spokesman Brett Fuchs. About 150 officers from several agencies responded. There was no shooter. The New York Times reports that an online group called "Purgatory" is "suspected of being connected to several of the episodes, including reports of shootings, according to cybersecurity experts, law enforcement agencies and the group members' own posts in a social media chat." (Though the Times, couldn't verify the group's claims.) Federal authorities previously connected the same network to a series of bomb scares and bogus shooting reports in early 2024, for which three men pleaded guilty this year... Bragging about its recent activities, Purgatory said that it could arrange more swatting episodes for a fee. USA Today tries to quantify the reach of swatting: Estimated swatting incidents jumped from 400 in 2011 to more than 1,000 in 2019, according to the Anti-Defamation League, which cited a former FBI agent whose expertise is in swatting. From January 2023 to June 2024 alone, more than 800 instances of swatting were recorded at U.S. elementary, middle and high schools, according to the K-12 School Shootings Database, created by a University of Central Florida doctoral student in response to the Parkland High School shooting in 2018.tise is in swatting... David Riedman, a data scientist and creator of the K-12 School Shooting Database, estimates that in 2023, it cost $82,300,000 for police to respond to false threats.

In 2017 Rick Beato streamed "Rick's Rant Episode 2" — and just received a copyright claim this month. Days after jazz pianist Chick Corea died in 2021, Beato livestreamed a half-hour video which was mostly commentary, but with several excerpts from Corea's albums (at least one more than three minutes long). He also received a copyright claim for that one this August — just minutes after the claim on his 2017 video. These videos "are all fair use," Beato argues in a new video, noting it's also affected other popular YouTube channels like The Professor of Rock: Rick Beato: Universal Music Group [UMG] has continued to send emails about copyright content ID claims — and now copyright strikes — on my channel. As a matter of fact, I have three shorts — these are under a minute long — that if they go through in the next four days, I'll have three strikes on my channel! Now if you don't fight these things, those three strikes would actually remove my channel from YouTube. Five months ago Rick Beato had posted a clip from his interview with singer-songwriter Adam Duritz (founder of The Counting Crows) on YouTube. After 250,000 views, he'd earned a whopping $36.52 — and then Universal Music Group also claimed that video violated their copyright. (In the background the video played Duritz's song as he described how he wrote it.) "So they're gonna take my channel down over less than a hundred bucks — for using a small segment from an interview with him, on a song he sang on," Beato complained on YouTube. "That video is 55 seconds long!" "You need to play people's music to talk about it," Beato argues. "That is the definition of fair use. These are interviews with the people about their careers." (And the interviews actually help promote the artists for the record labels...) Rick Beato: The next one has me in it — it's an Olivia Rodrigo song — that I played maybe 10 seconds of the song on, and the short is 42 seconds long. Who did it? UMG. The third copyright strike is from a Hans Zimmer short. It's also UMG — it's from the Crimson Tide soundtrack. Now, what do these things say...? "Your video is scheduled to be removed in four days and your channel will get a copyright strike due to a removal request from a claimant. If you delete your video before then, your channel won't get a copyright strike." [And there's also emails like "After reviewing your dispute, UMG has decided that their copyright claim is still valid..."] I've had probably 4,000 claims, over the last 9 years — from things that are fair use. [When he interviewed producer Rick Rubin, that video got 13 separate copyright claims.] That's when I hired a lawyer to fight these. [Full-time, Beato says later.] And what he's done is he fought every single claim... We have successfully fought thousands of these now. But it literally costs me so much money to do this. Since we've been fighting these things — and never lost one — they still keep coming in... They're all Universal Music Group. So they obviously have hired some third party company, that are dredging up things, they're looking for things that haven't been claimed in the past — they're taking videos from seven or eight years ago! Slashdot reader MrBrklyn (Slashdot reader #4,775) writes on the "New York's Linux Scene" site that video bloggers like Beato "have been hounded by copyright pirates like UMG," arguing that new videos of support are a "rebellion gaining traction". (Beato's video drew 1,369,859 views — and attracted 24,605 Comments — along with videos of support from professional musicians like drummer Anthony Edwards, guitarist Justin Hawkins, and bassist Scot Lade, as well as two different professional music attorneys.) "Since there's rarely humans making any of these decisions and it's automated by bots, they don't understand these claims are against Universal Music's best interests," argues the long-running blog Saving Country Music (first appearing on MySpace in 2008). On YouTube videos, creators can freely filch copyrighted photos and other people's videos virtually free of ramifications. You can take an entire 2 1/2 hour film, impose it over a background, and upload it to YouTube, and usually avoid any problems. But feature a barely audible 8 1/2-second clip of music underneath audio dialogue, and you could have your entire podcast career evaporate overnight... People continue to ask, "Why doesn't Saving Country Music has a podcast?" Because what's the point of having a music podcast when you can't feature music? In fact, after over a decade of refusing to start one, I finally did, music free. What happened? About a dozen episodes in, someone took out a claim, and not only were all the episodes deleted, so was the entire account, even though no music even appeared on any of the episodes. I was given absolutely no recourse to fight whatever false claim had been made... The music industry continues to so colossal fail the artists and catalogs they represent, and the fans they're supposed to serve with this current system of how podcasts are handled. If everything changes today thanks to the Rick Beato rant, it would still be 15 years too late. But at least it would happen. Instead, they write, "Music labels have been leaving major opportunities to promote their catalogs and performers on the table with their punitive copyright claims that make it impossible to feature music on music podcasts and other platforms... "You aren't screwing podcasters. You're screwing artists who could be using podcasts to help promote their music. "

"For months, tens of thousands of people around the world have been complaining Meta has been banning their Instagram and Facebook accounts in error..." the BBC reported this month... More than 500 of them have contacted the BBC to say they have lost cherished photos and seen businesses upended — but some also speak of the profound personal toll it has taken on them, including concerns that the police could become involved. Meta acknowledged a problem with the erroneous banning of Facebook Groups in June, but has denied there is wider issue on Facebook or Instagram at all. It has repeatedly refused to comment on the problems its users are facing — though it has frequently overturned bans when the BBC has raised individual cases with it. One examples is a woman lost the Instagram profile for her boutique dress shop. ("Over 5,000 followers, gone in an instant.") "After the BBC sent questions about her case to Meta's press office, her Instagram accounts were reinstated... Five minutes later, her personal Instagram was suspended again — but the account for the dress shop remained." Another user spent a month appealing. ("In June, the BBC understands a human moderator double checked," but concluded he'd breached a policy.) And then "his account was abruptly restored at the end of July. 'We're sorry we've got this wrong,' Instagram said in an email to him, adding that he had done nothing wrong." Hours after the BBC contacted Meta's press office to ask questions about his experience, he was banned again on Instagram and, for the first time, Facebook... His Facebook account was back two days later — but he was still blocked from Instagram. None of the banned users in the BBC's examples were ever told what post breached the platform's rules. Over 36,000 people have signed a petition accusing Meta of falsely banning accounts; thousands more are in Reddit forums or on social media posting about it. Their central accusation — Meta's AI is unfairly banning people, with the tech also being used to deal with the appeals. The only way to speak to a human is to pay for Meta Verified, and even then many are frustrated. Meta has not commented on these claims. Instagram states AI is central to its "content review process" and Meta has outlined how technology and humans enforce its policies. The Guardian reports there's been "talk of a class action against Meta over the bans." Users report Meta has typically been unresponsive to their pleas for assistance, often with standardised responses to requests for review, almost all of which have been rejected... But the company claims there has not been an increase in incorrect account suspension, and the volume of users complaining was not indicative of new targeting or over-enforcement. "We take action on accounts that violate our policies, and people can appeal if they think we've made a mistake," a spokesperson for Meta said. "It happened to me this morning," writes long-time Slashdot reader Daemon Duck," asking if any other Slashdot readers had their personal (or business) account unreasonably banned. (And wondering what to do next...)

This week's round of HID subsystem "fixes" for the in-development Linux 6.17 kernel include adding a number of new device IDs and other alterations for supporting new hardware...

At the moment, the Spotify exodus of 2025 is a trickle rather than a flood, writes the Guardian, citing the departure of five notable bands "liked in indie circles," but not "the sorts to rack up billions of listens." "Still, it feels significant if only because, well, this sort of thing wasn't really supposed to happen any more." Plenty of bands and artists refused to play ball with Spotify in its early years, when the streamer still had work to do before achieving total ubiquity. But at some point there seemed to a collective recognition that resistance was futile, that Spotify had won and those bands would have to bend to its less-than-appealing model... This artist acquiescence happened in tandem — surely not coincidentally — with a closer relationship between Spotify and the record labels that once viewed it as their destroyer. Some of the bigger labels have found a way to make a lot of money from streaming: Spotify paid out $10bn in royalties last year — though many artists would point out that only a small fraction of that reaches them after their label takes its share... So why have those five bands departed in quick succession? The trigger was the announcement that Spotify founder Daniel Ek had led a €6oom fundraising push into a German defence company specialising in AI weapons technology. That was enough to prompt Deerhoof, the veteran San Francisco oddball noise pop band, to jump. "We don't want our music killing people," was how they bluntly explained their move on Instagram. That seems to have also been the animating factor for the rest of the departed, though GY!BE, who aren't on any social media platforms, removed their music from Spotify — and indeed all other platforms aside from Bandcamp — without issuing a statement, while Hotline TNT's statement seemed to frame it as one big element in a broader ideological schism. "The company that bills itself as the steward of all recorded music has proven beyond the shadow of a doubt that it does not align with the band's values in any way," the statement read. That speaks to a wider artist discontent in a company that has, even by its own standards, had a controversial couple of years. There was of course the publication of Liz Pelly's marmalade-dropper of a book Mood Machine, with its blow-by-blow explanation of why Spotify's model is so deleterious to musicians, including allegations that the streamer is filling its playlists with "ghost artists" to further push down the number of streams, and thus royalty payments, to real artists (Spotify denies this). The streamer continues to amend its model in ways that have caused frustration — demonetising artists with fewer than 1,000 streams, or by introducing a new bundling strategy resulting in lower royalty fees. Meanwhile, the company — along with other streamers — has struggled to police a steady flow of AI-generated tracks and artists on to the platform... [R]emoving yourself from such an important platform is highly risky. But if they can pull it off, the sacrifice might just be worth it. "A cooler world is possible," as Hotline TNT put it in their statement. The Guardian's culture editor adds that "I've been using Bandcamp more, even — gasp — buying albums..." "Maybe weaning ourselves off not just Spotify, but the way that Spotify has convinced us to consume music is the only answer. Then a cooler world might be possible."

Intel amended its deal with the U.S. Department of Commerce "to remove earlier project milestones," reports Reuters, "and received about $5.7 billion in cash sooner than planned." "The move will give Intel more flexibility over the funds." The amended agreement, which revises a November 2024 funding deal, retains some guardrails that prevent the chipmaker from using the funds for dividends and buybacks, doing certain control-changing deals and from expanding in certain countries. The move makes the Wall Street Journal wonder what, beyond equity, the U.S. now gets in return, calling government's position "a stake without a strategy." The U.S. has historically shied away from putting money into private business. It can't really outguess the market on where the most promising returns lie. Yet there are exceptions. Sometimes a company or industry risks failing without public support, and that failure would hurt the whole country, not just its shareholders and employees. Intel meets both conditions. It isn't failing, but it is losing money, its core business is in decline, and it lacks the capital and customers needed to make the most advanced semiconductors. If Intel were to fail, it would take a sizable chunk of the semiconductor industrial base with it. At a time of existential competition with China, that is a national emergency... [U.S. Commerce Secretary Howard Lutnick] said as a shareholder, the U.S. would help Intel "to create the most advanced chips in the world." And yet the deal doesn't provide Intel with new resources to accomplish that. Rather, to get the remaining $9 billion, Intel had to give the U.S. equity. This is more like a tax than an investment: Shareholders gave up a 10th of their ownership in return for money the company was supposed to get anyway... Some of the administration's forays into private business do reflect strategic thinking, such as the Pentagon's 15% stake in MP Materials in exchange for investment and contracts that help make the company a viable alternative to China as a supplier of rare-earth magnets for products such as automobiles, wind turbines, jet fighters and missile systems. But more often, companies recoil from government ownership... Though the U.S. stake dilutes Intel's existing shareholders, its stock has held up. There could be several reasons. It eliminates uncertainty over whether the remaining $9 billion in federal funds will be forthcoming... [B]ecause Washington has a vested interest in Intel's share price, investors believe it may prod companies such as Nvidia and Apple to buy more of its chips. But that only goes so far, the article seems to conclude, offering this quote from an analyst Bernstein investment research. "If Intel can prove they can make these leading-edge products in high volume that meets specifications at a good cost structure, they'll have customers lined up around the block. If they can't prove they can do it, what customer will put meaningful volume to them regardless of what pressure the U.S. government brings to bear?" CBS News also notes the U.S. government stake "is being criticized by conservatives and some economic policy experts alike, who worry such extensive government intervention undermines free enterprise."

After Will Smith uploaded a video of an adoring crowd, blogger Andy Baio "conducted a detailed analysis that suggests Will Smith's team might have used AI to turn photos from his recent concerts into videos," writes BGR. But there's more to the story: Google recently ran an experiment for YouTube Shorts in which it used AI (machine learning) to improve the quality of Shorts without asking the creator for permission. People complained the videos looked like they were AI generated. It seems that Will Smith's YouTube Shorts clip that attracted criticism from fans this week might have been a victim of this experiment... The signs are real. The man who claimed Will Smith's song helped him cure cancer was there. The woman in front of him was holding the sign with him. The "Lov U" sign appeared in photos the singer posted on his social media channels before the clip was shared. "Will Smith has not denied the use of AI in these promotional clips," the article adds. But the Hollywood Reporter also calls it "just the beginning of AI chaos," noting that "influencers and spinmeisters have been using AI upscaling for years, if quietly, the way you might round up your current salary in a job interview." It's only going to grow more popular as the tools get better. (And they will — you just need some tweaks to the model and increases in compute to erase these hallucinations.) In fact, when the chapter on the early AI Age is written, the line about this moment is less likely to be, "Remember when Will Smith did something cringily AI?" and more, "Remember when AI was still seen as so cringe that we made fun of Will Smith for it?" Experts differ on the timeline, but everyone agrees it's just years if not months before we'll stop being able to spot an AI video. [Will Smith's video] had the particular misfortune of coming out at this interregnum moment: good enough for someone to use but not so good we can't spot it. That moment will be over soon enough, and, I suspect, so will our pearl-clutching. The main effect of this new age of the synthetic is that video will stop being a meaningful measure of truth. We have long stopped believing everything we read, and AI image-generators have killed what photoshop wounded. But video until now has been the last bastion of objectivity — incontrovertible evidence that an event took place the way it seemed to.... But there is an upside. (Really.) Without a format that can telegraph objectivity, we'll need to (if we care to) turn to other ways to assure ourselves of the facts: the source of the video. That could mean the human-led content creator will matter more. After years of seeing news brands take a beating in the trust department, they'll soon become the only hope we have of knowing whether something happened. We no longer will be able to trust the medium. But we may newly believe the media.

They offer "a self-sustaining power solution for marine regions," according to a newly published 41-page review after "pioneering use in wave energy harvesting in 2014". Ten years later, researchers have developed several structures for these "triboelectric nanogenerators" (TENGs) to "facilitate their commercial deployment." But there's a lack of "comprehensive summaries and performance evaluations". So the review "distills a decade of blue-energy research into six design pillars" for next-generation technology, writes EurekaAlert, which points the way "to self-powered ocean grids, distributed marine IoT, and even hydrogen harvested from the sea itself..." By "translating chaotic ocean motion into deterministic electron flow," the team "turns every swell, gust and glint of sunlight into dispatchable power — ushering in an era where the sea itself becomes a silent, self-replenishing power plant." Some insights: - Multilayer stacks, origami folds and magnetic-levitation frames push volumetric power density...three orders of magnitude above first-generation prototypes. - Frequency-complementary couplings of TENG, EMG and PENG create full-spectrum harvesters that deliver 117 % power-conversion efficiency in real waves. - Pendulum, gear and magnetic-multiplier mechanisms translate chaotic 0.1-2 Hz swells into stable high-frequency oscillations, multiplying average power 14-fold. - Resonance-tuned structures now span 0.01-5 Hz, locking onto shifting wave spectra across seasons and sea states. - Spherical, dodecahedral and tensegrity architectures harvest six-degree-of-freedom motion, eliminating orientational blind spots. - Single devices co-harvest wave, wind and solar inputs, powering self-charging buoys that cut battery replacement to zero... Another new wave energy project is moving forward, according to the blog Renewable Energy World: Eco Wave Power, an onshore wave energy technology company, announced that its U.S. pilot project at the Port of Los Angeles has successfully completed operational testing and achieved a new milestone: the lowering of its floaters into the water for the first time. The moment, broadcast live by Good Morning America, follows the finalization of all installation works at the project site, including full installation of all wave energy floaters; connection of hydraulic pipes and supporting infrastructure; and placement of the onshore energy conversion unit. With installation completed, Eco Wave Power has now officially entered the operational phase of its U.S. excursion... [Inna Braverman, founder and CEO of Eco Wave Power] said "This pilot station is a vital step in demonstrating how wave energy can be harnessed using existing marine infrastructure, while laying the groundwork for full-scale commercialization in the United States...." Eco Wave Power's patented onshore wave energy system attaches floaters to existing marine structures. The up-and-down motion of the waves drives hydraulic cylinders, which send pressurized fluid to a land-based energy conversion unit that generates electricity... The U.S. Department of Energy's National Renewable Energy Laboratory estimates that wave energy has the potential to generate over 1,400 terawatt-hours per year — enough to power approximately 130 million homes. Eco Wave Power's 404.7 MW global project pipeline also includes upcoming operational sites in Taiwan, India, and Portugal, alongside its grid-connected station in Israel. Long-time Slashdot reader PongoX11 also brings word of a company building a "simple" floating rig to turn wave motion into electricity, calling it "a steel can that moves water around" and wondering if "This one might work!" The news site TechEBlog points out that "Unlike old-school wave energy systems with clunky mechanical parts, Ocean-2 rocks a modular, flexible setup that rolls with the ocean's flow." At about 10 meters wide [30 feet wide. and 260 feet long!], it is made from materials designed to (hopefully) withstand the ocean's abuse, over some maintenance cycle. It's designed for deep ocean, so solving this technically is the first big challenge. Figuring out how to use/monetize all that cheap energy out in the middle of nowhere will be the next. "Ocean-2 works with the ocean, not against it, so we can generate power without messing up marine life," said Panthalassa's CEO, Dr. Elena Martinez, according to TechEBlog: Tests in Puget Sound, done with Everett Ship Repair, showed it pumping out up to 50 kilowatts in decent conditions — enough juice for a small coastal town. "We're thinking big," Martinez said in a press release. "Ocean-2 is just the start, but we're already planning bigger arrays that could crank out gigawatts..." Looking forward, Panthalassa sees Ocean-2 as part of a massive wave energy network. By 2030, they're aiming to roll out arrays that could power whole coastal cities, cutting down on fossil fuel use.

When it comes to nuclear fusion energy, "How do we advance fusion as fast as possible?" asks the CEO of Commonwealth Fusion Systems. They've just raised $863 million from Nvidia, Google, the BIll Gates-founded Breakthrough Energy Ventures and nearly two dozen more investors, which "may prove helpful as the company develops its supply chain and searches for partners to build its power plants and buy electricity," reports TechCrunch. Commonwealth's CEO/co-founder Bob Mumgaard says "This round of capital isn't just about fusion just generally as a concept... It's about how do we go to make fusion into a commercial industrial endeavor." The Massachusetts-based company has raised nearly $3 billion to date, the most of any fusion startup. Commonwealth Fusion Systems (CFS) previously raised a $1.8 billion round in 2021... CFS is currently building a prototype reactor called Sparc in a Boston suburb. The company expects to turn that device on later next year and achieve scientific breakeven in 2027, a milestone in which the fusion reaction produces more energy than was required to ignite it. Though Sparc isn't designed to sell power to the grid, it's still vital to CFS's success. "There are parts of the modeling and the physics that we don't yet understand," Saskia Mordijck, an associate professor of physics at the College of William and Mary, told TechCrunch. "It's always an open question when you turn on a completely new device that it might go into plasma regimes we've never been into, that maybe we uncover things that we just did not expect." Assuming Sparc doesn't reveal any major problems, CFS expects to begin construction on Arc, its commercial-scale power plant, in Virginia starting in 2027 or 2028... "We know that this kind of idea should work," Mordijck said. "The question is naturally, how will it perform?" Investors appear to like what they've seen so far. The list of participants in the Series B2 round is lengthy. No single investor led the round, and a number of existing investors increased their stakes, said Ally Yost, CFS's senior vice president of corporate development... The new round will help CFS make progress on Sparc, but it will not be enough to build Arc, which will likely cost several billion dollars, Mumgaard said. "As advances in computing and AI have quickened the pace of research and development, the sector has become a hotbed of startup and investor activity," the article points out. And CEO Mumgaard told TechCrunch that their Sparc prototype will prove the soundness of the science — but it's also important to learn "the capabilities that you need to be able to deliver it. It's also to have the receipts, know what these things cost!"

Mise à jour du 30 août à 21h00. 2h30 après le début de la panne, le CIC et le Crédit Mutuel ont enfin communiqué sur l’incident : « Un dysfonctionnement interne a empêché ce jour, entre 17h20 et 19h30, les paiements et retraits par carte bancaire de nos clients. La cause interne de l’incident a été identifiée et résolue grâce à la mobilisation de nos équipes informatiques », explique le CIC sur X.com.

Même communication au Crédit Mutuel (les deux banques appartiennent au même groupe), avec une petite précision supplémentaire : les « sociétaires et clients de 16 fédérations » étaient affectés. CIC et Crédit Mutuel s’excusent auprès de ses clients et des commerçants.

Aucun détail technique n’est par contre donné par l’une ou l’autre des enseignes.

Brief du 30 août à 19h38. Dernier week-end d’aout et derniers jours avant la reprise des cours pour bon nombre de français… Mais cette journée est ponctuée par une panne affectant les clients CIC et Crédit Mutuel qui ne peuvent plus payer par carte bancaire ou retirer de l’argent. Des millions de clients sont donc concernés.

Les messages affluent de partout sur les réseaux sociaux, le problème est national. Dans les magasins, les clients doivent donc trouver un autre moyen de payer que leur carte CIC ou Crédit Mutuel (autre banque, chèque, espèce).

Il est par contre possible de créditer de l’argent sur une carte CIC, nous en avons fait l’expérience. Vers 18 h, un membre de la rédaction a également pu valider un paiement par Internet avec une CB du Crédit Mutuel. N’hésitez pas à nous faire part de vos retours sur cette panne.

La panne a commencé en fin d’après midi selon les retours (vers 17h00) mais, faute de communication, les spéculations vont bon train. En effet, aucune des deux banques n’a pour le moment communiqué auprès de ses clients – notification sur l’application mobile (qui fonctionne), ou autre canal – ni sur les réseaux sociaux. De leur côté, les commerçants ne semblent pas avoir plus d’informations pour le moment.

Nous mettrons à jour ce brief quand nous aurons de plus amples détails.

Mise à jour du 30 août à 21h00. 2h30 après le début de la panne, le CIC et le Crédit Mutuel ont enfin communiqué sur l’incident : « Un dysfonctionnement interne a empêché ce jour, entre 17h20 et 19h30, les paiements et retraits par carte bancaire de nos clients. La cause interne de l’incident a été identifiée et résolue grâce à la mobilisation de nos équipes informatiques », explique le CIC sur X.com.

Même communication au Crédit Mutuel (les deux banques appartiennent au même groupe), avec une petite précision supplémentaire : les « sociétaires et clients de 16 fédérations » étaient affectés. CIC et Crédit Mutuel s’excusent auprès de ses clients et des commerçants.

Aucun détail technique n’est par contre donné par l’une ou l’autre des enseignes.

Brief du 30 août à 19h38. Dernier week-end d’aout et derniers jours avant la reprise des cours pour bon nombre de français… Mais cette journée est ponctuée par une panne affectant les clients CIC et Crédit Mutuel qui ne peuvent plus payer par carte bancaire ou retirer de l’argent. Des millions de clients sont donc concernés.

Les messages affluent de partout sur les réseaux sociaux, le problème est national. Dans les magasins, les clients doivent donc trouver un autre moyen de payer que leur carte CIC ou Crédit Mutuel (autre banque, chèque, espèce).

By exploiting two-color beams, researchers "can generate ordered chains and lattices," reports ScienceDaily, "with tunable topology — potentially revolutionizing data storage, communications, and photonic processing." An internationally joint research group between Singapore and Japan has unveiled a blueprint for arranging exotic, knot-like patterns of light into repeatable crystals that extend across both space and time. The work lays out how to build and control "hopfion" lattices using structured beams.. three-dimensional topological textures whose internal "spin" patterns weave into closed, interlinked loops. They have been observed or theorized in magnets and light fields, but previously they were mainly produced as isolated objects. The authors show how to assemble them into ordered arrays that repeat periodically, much like atoms in a crystal, only here the pattern repeats in time as well as in space. The key is a two-color, or bichromatic, light field whose electric vector traces a changing polarization state over time. By carefully superimposing beams with different spatial modes and opposite circular polarizations, the team defines a "pseudospin" that evolves in a controlled rhythm. When the two colors are set to a simple ratio, the field beats with a fixed period, creating a chain of hopfions that recur every cycle. Starting from this one-dimensional chain, the researchers then describe how to sculpt higher-order versions whose topological strength can be dialed up or down... Topological textures like skyrmions have already reshaped ideas for dense, low-error data storage and signal routing. Extending that toolkit to hopfion crystals in light could unlock high-dimensional encoding schemes, resilient communications, atom trapping strategies, and new light-matter interactions. "The birth of space-time hopfion crystals," the authors write, opens a path to condensed, robust topological information processing across optical, terahertz, and microwave domains.
