Une procédure judiciaire est en cours à l'encontre de CORSAIR et de ses barrettes de mémoire vive. Le principe de la plainte déposée contre la marque est assez simple à cerner, même si bon nombre d'entre vous risquez de penser que c'est exagéré ou, en tout cas, que l'ensemble des fabricants de barre...

Pilot Union Urges FAA To Reject Rainmaker's Drone Cloud-Seeding Plan

An anonymous reader quotes a report from TechCrunch: Rainmaker Technology's bid to deploy cloud-seeding flares on small drones is being met by resistance from the airline pilots union, which has urged the Federal Aviation Administration to consider denying the startup's request unless it meets stricter safety guidelines. The FAA's decision will signal how the regulator views weather modification by unmanned aerial systems going forward. Rainmaker's bet on small drones hangs in the balance. The Air Line Pilots Association (ALPA) told the FAA that Rainmaker's petition "fails to demonstrate an equivalent level of safety" and poses "an extreme safety risk." Rainmaker is seeking an exemption from rules that bar small drones from carrying hazardous materials. The startup filed in July, and the FAA has yet to rule. Instead, it issued a follow-up request for information, pressing for specifics on operations and safety. In its filing, Rainmaker proposed using two flare types, one "burn-in-place" and the other ejectable, on its Elijah quadcopter, to disperse particles that stimulate precipitation. Elijah has a maximum altitude of 15,000 feet MSL (measured from sea level), which sits inside controlled airspace where commercial airliners routinely fly. Drones need permission from Air Traffic Control to fly inside this bubble. Rainmaker's petition says it will operate in Class G (uncontrolled) airspace unless otherwise authorized. ALPA notes the filing doesn't clearly state where flights would occur or what altitudes would be used. Rainmaker and ALPA did not reply to TechCrunch's requests for comment. The union also objects to the flares themselves, citing concerns about foreign object debris and fire safety. ALPA points out that the petition does not include trajectory modeling of the ejectable casings or analysis on the environmental impacts of chemical agents. However, Rainmaker says the flights will occur over rural areas and over properties owned by private landlords "with whom Rainmaker has developed close working relationships." [...] What happens next hinges on whether the FAA thinks those mitigations are sufficient. However it's decided, the agency's response will likely set the tone for novel cloud-seeding approaches.

Quick Charge 5+ : Qualcomm veut charger vite et plus intelligemment nos batteries

✇MiniMachines.net

Charger vite, tout le monde le fait. Les protocoles se sont multipliés et les constructeurs ont quasiment tous le leur. Depuis cinq ans Qualcomm propose la formule Quick Charge 5 et semble satisfait de son protocole. Du moins d’un point de vue vitesse. On l’a vu dernièrement, les batteries ont des petits problèmes un peu partout. Chauffe, incendies et perte d’autonome très rapide, il est temps de passer de recharger vite à recharger vite et bien.

C’est ainsi que Qualcomm présente le Quick Charge 5+, une évolution qui veut assagir la charge rapide. Un argument qui peut avoir du sens quand on réfléchit aux tarifs des engins à recharger. L’idée est de proposer une meilleure durée de vie aux batteries.

Avec une puissance dépassant les 100 watts, le Quick Charge 5 proposait de remettre d’aplomb rapidement. L’idée était de connecter son smartphone 5 minutes à la prise électrique d’une gare ou d’un amphi et de repartir avec une batterie rechargée de moitié. Une capacité forcément pratique pour éviter de se retrouver « à sec » en milieu de journée. Mais cette approche assez agressive de la charge a ses inconvénients. Surchauffe de la batterie et de l’appareil et vieillissement des cellules pouvant amener à une perte d’autonomie. Ce qui entraine un comportement problématique puisque la baisse de capacité des batteries demande des recharges rapides plus régulières encore.

Qualcomm ne compte pas ralentir la cadence et promet une charge de 140 watts en 20 volts et pouvant aller jusqu’à 7 ampères. Ce qui va changer c’est la manière dont cette charge sera dispensée. avec Quick Charge 5+ l’intensité de la charge sera ajustée en temps réel suivant les remontées constatées par le système. Un dialogue entre l’électronique de la batterie et le chargeur permettra de trouver le meilleur compromis entre vitesse et sécurité. Il s’agit là d’un mécanisme assez classique que l’on rencontre dans d’autres secteurs et que des concurrents à Qualcomm emploient déjà.

Cette approche a un autre intérêt qui s’est surtout développé ces dernières années. La possibilité de connecter au secteur des engins pendant qu’ils sont employés sans que ceux-ci entrent en surchauffe. On pourra travailler, regarder des vidéos ou travailler en jonglant entre la puissance de calcul embarquée et la chauffe générée d’u côté. Et le besoin de charge plus ou moins rapide de la batterie. Smartphone, consoles, tablettes et ordinateurs portables sauront en tirer parti.

Le gros avantage du Quick Charge 5+ c’est le parc déjà installé et la rétrocompatibilité des chargeurs. Non seulement les nouveaux dispositifs accepteront les appareils de génération Quick Charge 2.0 vieille de déjà 10 ans mais le protocole saura piloter des solutions concurrentes.

Comme d’habitude avec Qualcomm, ce dispositif sera l’occasion de vendre des licences d’exploitation pour que d’autres acteurs s’en emparent et livrent des chargeurs adaptés. Ce sera également l’occasion de mettre en avant ses nouveaux SoCs qui assureront le dialogue avec la batterie nativement.

E-Bike Injuries Are a Massive Burden, Say Surgeons

✇Slashdot
Par :BeauHD
13 septembre 2025 à 10:00
Surgeons in London report a surge in severe e-bike-related injuries, putting major strain on NHS trauma units. The BBC mentions a couple e-bike accidents overheard at the Royal London Hospital in Whitechapel. "A 32-year-old, fit and well student... a couple of days ago he fell off an e-bike sustaining a closed left tibial plateau fracture." Another case involved a little girl named Frida: "Six-year-old girl, she was hit by an electric bike, she has a closed tib/fib fracture." From the report: Surgeon Jaison Patel is seeing more and more cases like this. "It's a massive burden on our department and I'm sure it's the same across the whole of London," he tells us. "If we can reduce the number of patients coming in with these sorts of injuries it would be great for the patients obviously, but also takes massive pressure off us in the NHS." Jaison deals with lower limb injuries. Just along the corridor his colleague Nick Aresti does the upper limbs. Nick explains that he is a cyclist himself, and it's something he encourages people to do for the benefit of their health. But, he has real concerns about e-bikes, and says: "What we've noticed with e-bikes is that the speed in which people are coming off is much higher and as a result, the injuries are much worse." He shows us X-rays of someone who has broken their collarbone. He explains that with e-bikes, the injuries they're seeing are much more severe, and as such, people are "struggling to get back to normality." Nick and Jaison both agree it's something they're seeing increasingly more of as time goes by, and they think the industry needs better regulation. "We should do something about it, I don't think we can let this carry on," Jaison says. Over recent days of course, thousands of Londoners have taken to e-bikes to help beat the strikes. For many it has been an essential way to get about. Currently, anyone aged 14 or over can legally ride an e-bike. The power output of an e-bike's motor should be capped at 250 watts, and the motor should not be capable of propelling the bike any faster than 15.5mph (25kph), according to government rules. London's Walking and Cycling Commissioner Will Norman says the rules need changing and says better regulation of the rentable electric bikes could be on the way. "We need to ensure that the vehicles are safe, that there's parking, they're not scattered all over the place, and that the batteries are safe," he says. "I'm really delighted that the government has now indicated in its English Devolution Bill that London and other cities across the UK will be getting more powers so again we can start regulating that, to ensure that they're safe for people to use and operate while they get around". The bill is currently going through parliament, and as yet there is no date for when it will be passed. Duncan Dollimore, head of campaigns at Cycling UK, who are members of the Electric Bike Alliance, argues against the regulation of e-bike usage. "The cost of inactivity-related health issues to the NHS each year is 7.4 billion pounds, and people cycling saves them 1 billion pounds. We have seen a slight rise in the number of incidents involving hired e-bikes in London, but the health benefits of people cycling outweigh the risks by around 20 to one."

AORUS RTX 5060 Ti AI BOX eGPU : une RTX 5060 Ti externe en Thunderbolt 5

Le dock graphique AORUS RTX 5060 Ti AI BOX eGPU de Gigabyte ne mesure que 24.3 cm de haut pour 11.7 cm de profondeur et 4.5 cm de large. Il se pose sur un bureau et se connecte à un ordinateur portable ou un MiniPC en Thunderbolt 5 pour lui apporter plus de compétences graphiques.

À l’intérieur, on retrouve une solution Nvidia GeForce RTX 5060 Ti avec 16 Go de mémoire vive. Une solution entrée de gamme pour le jeu, mais largement suffisante pour énormément de profils de joueurs. Elle apportera des capacités d’usages plus sérieux assez variées. Le constructeur a choisi l’angle de l’Intelligence Artificielle puisque aujourd’hui même un déodorant est enrichi à l’IA. Mais on pourra l’employer pour jouer – avec DLSS4 – , travailler, exécuter des outils de calculs lourds, faire de la 2D, du montage vidéo et autres sans souci. 

La AORUS RTX 5060 Ti AI BOX eGPU est donnée comme 5% moins rapide en mode Thunderbolt 5 que la même puce graphique montée directement en PCIe. Le format du boitier est assez explicite, il s’agit bien d’une solution de bureau embarquée en PCIe 4.0 x4. Pas tout à fait la même bande passante qu’un PCIe 4.0 x16 classique mais pas vraiment un souci pour ce type de puce. La ventilation est assurée par un système Windforce lui aussi hérité des compétences de Gigabyte dans le monde des cartes graphiques. Autre compétence héritée du monde gamer Aorus, des LEDs RGB qui viendront égayer le logo en façade parce que pourquoi pas.

L’usage du Thunderbolt 5 maintient également le protocole USB4 ce qui va permettre de récupérer un peu de connectique en plus sur la partie dock : trois ports USB 3.2 Type-A Gen2, une fonction PowerDelivery 3.0 pour recharger son portable via le dock et un Ethernet non détaillé. On pourra donc connecter le AORUS RTX 5060 Ti AI BOX eGPU au réseau Ethernet, lui brancher des manettes de jeu ou autres et retrouver ces capacités sur un portable une fois connecté avec un simple câble USB Type-C. Cela permettra de jouer ou travailler tout en rechargeant sa batterie. 

Pas de prix, pas de date de commercialisation pour le moment. Juste une page d’info sur le site de la marque. Je ne serais pas surpris que d’autres concurrents déclinent à leur tour ce même concept.

Synthetic Magnetic Fields Steer Light On a Chip For Faster Communications

✇Slashdot

13 septembre 2025 à 07:00
Researchers in China have created synthetic magnetic fields within silicon photonic crystals, allowing them to steer and control light on a chip with unprecedented precision. "Beyond immediate applications, the work opens new avenues for studying quantum-inspired phenomena with light," reports Phys.org. "The ability to impose artificial gauge fields in photonic systems could enable devices for optical computing, quantum information, and advanced communication technologies." Slashdot reader alternative_right shares an excerpt from the report: The team achieved this by systematically altering the symmetry of tiny repeating units in silicon photonic crystals. Adjusting the degree of local asymmetry at each point allowed them to 'design' pseudomagnetic fields with tailored spatial patterns, without breaking fundamental time-reversal symmetry. Both theoretical analysis and experiments confirmed that these engineered fields can guide and manipulate light in versatile ways. To demonstrate practical applications, the researchers built two devices commonly used in integrated optics. One was a compact S-shaped waveguide bend that transmitted light with less than 1.83 decibels of signal loss. The other was a power splitter that divided light into two equal paths with low excess loss and minimal imbalance. In a final test, the devices successfully transmitted a high-speed data stream at 140 gigabits per second using a standard telecommunications modulation format, showing that the technique is compatible with existing optical communication systems. The research has been published in Advanced Photonics.

Proton Mail Suspended Journalist Accounts At Request of Cybersecurity Agency

✇Slashdot

13 septembre 2025 à 03:30
An anonymous reader quotes a report from The Intercept: The company behind the Proton Mail email service, Proton, describes itself as a "neutral and safe haven for your personal data, committed to defending your freedom." But last month, Proton disabled email accounts belonging to journalists reporting on security breaches of various South Korean government computer systems following a complaint by an unspecified cybersecurity agency. After a public outcry, and multiple weeks, the journalists' accounts were eventually reinstated -- but the reporters and editors involved still want answers on how and why Proton decided to shut down the accounts in the first place. Martin Shelton, deputy director of digital security at the Freedom of the Press Foundation, highlighted that numerous newsrooms use Proton's services as alternatives to something like Gmail "specifically to avoid situations like this," pointing out that "While it's good to see that Proton is reconsidering account suspensions, journalists are among the users who need these and similar tools most." Newsrooms like The Intercept, the Boston Globe, and the Tampa Bay Times all rely on Proton Mail for emailed tip submissions. Shelton noted that perhaps Proton should "prioritize responding to journalists about account suspensions privately, rather than when they go viral." On Reddit, Proton's official account stated that "Proton did not knowingly block journalists' email accounts" and that the "situation has unfortunately been blown out of proportion." The two journalists whose accounts were disabled were working on an article published in the August issue of the long-running hacker zine Phrack. The story described how a sophisticated hacking operation -- what's known in cybersecurity parlance as an APT, or advanced persistent threat -- had wormed its way into a number of South Korean computer networks, including those of the Ministry of Foreign Affairs and the military Defense Counterintelligence Command, or DCC. The journalists, who published their story under the names Saber and cyb0rg, describe the hack as being consistent with the work of Kimsuky, a notorious North Korean state-backed APT sanctioned by the U.S. Treasury Department in 2023. As they pieced the story together, emails viewed by The Intercept show that the authors followed cybersecurity best practices and conducted what's known as responsible disclosure: notifying affected parties that a vulnerability has been discovered in their systems prior to publicizing the incident. Phrack said the account suspensions created a "real impact to the author. The author was unable to answer media requests about the article." Phrack noted that the co-authors were already working with affected South Korean organizations on responsible disclosure and system fixes. "All this was denied and ruined by Proton," Phrack stated. Phrack editors said that the incident leaves them "concerned what this means to other whistleblowers or journalists. The community needs assurance that Proton does not disable accounts unless Proton has a court order or the crime (or ToS violation) is apparent."

US EV Sales Smash Records In August

US EV sales hit a record 146,332 in August, grabbing nearly 10% of all new car sales, according to Kelley Blue Book. That's the highest yet and up from 9.1% in July. Electrek reports: With the federal EV tax credit set to expire on September 30, analysts say Q3 2025 is shaping up to be the strongest quarter for EV sales in US history. The current record holder is Q4 2024, when 365,824 EVs were sold. Prices ticked higher, too. The average transaction price (ATP) for an EV in August was $57,245, 3.1% more than July's revised lower ATP of $55,562. Year-over-year, though, EV prices were basically flat, down just 0.1%. The wave of EV sales also helped push up the overall market's ATP. Incentives, while not as high as July's record, remained hefty. EV buyers received discounts averaging over $9,000 in August, equal to 16% of ATP. That's more than double the incentive rate in the overall auto market and up from 13.6% a year ago. A separate report from Rho Motion found that global EV sales surged 25% in 2025, led by strong growth in Europe and China. "That amounts to 12.5 million EVs, although the data combines both battery EVs and plug-in hybrid EVs for the total," reports Ars Technica. As for North America? "EV sales are still growing but barely -- up just 6 percent between January and August 2025 compared to the same time period in 2024."

Newfoundland's 10-Year Education Report Calling For Ethical AI Use Contains Over 15 Fake Sources

✇Slashdot
Par :BeauHD
13 septembre 2025 à 01:10
Newfoundland and Labrador's 10-year Education Accord report (PDF) intended to guide school reform has been found to contain at least 15 fabricated citations, including references to non-existent films and journals. Academics suggest the fake sources may have been generated by AI. "There are sources in this report that I cannot find in the MUN Library, in the other libraries I subscribe to, in Google searches. Whether that's AI, I don't know, but fabricating sources is a telltale sign of artificial intelligence," said Aaron Tucker, an assistant professor at Memorial whose current research focuses on the history of AI in Canada. "The fabrication of sources at least begs the question: did this come from generative AI?" CBC News reports: In one case, the report references a 2008 movie from the National Film Board called Schoolyard Games. The film doesn't exist, according to a spokesperson for the board. But the exact citation used in the report can be found in a University of Victoria style guide -- a document that clearly lists fake references designed as templates for researchers writing a bibliography. "Many citations in this guide are fictitious," reads the first page of the document. "Errors happen. Made-up citations are a totally different thing where you essentially demolish the trustworthiness of the material," said Josh Lepawsky, the former president of the Memorial University Faculty Association who resigned from the report's advisory board last January, citing a "deeply flawed process" leading to "top-down" recommendations. The 418-page Education Accord NL report took 18 months to complete and was unveiled Aug. 28 by its co-chairs Anne Burke and Karen Goodnough, both professors at Memorial's Faculty of Education. The pair released the report alongside Education Minister Bernard Davis. "We are investigating and checking references, so I cannot respond to this at the moment," wrote Goodnough in an email declining an interview Thursday. In a statement, the Department of Education and Early Childhood Development said it was aware of a "small number of potential errors in citations" in the report. "We understand that these issues are being addressed, and that the online report will be updated in the coming days to rectify any errors."

Employee Who Leaked 'Spider-Man' Blu-ray Sentenced to Nearly 5 Years Prison

✇Slashdot

13 septembre 2025 à 00:30
A former Memphis disc manufacturing employee has been sentenced to nearly five years in prison after stealing pre-release Blu-rays from his employer and leaking them online. While he received 21 months for copyright infringement, a concurrent firearm charge extended his total prison term to 57 months. TorrentFreak reports: In February, the U.S. Department of Justice indicted 37-year-old Steven Hale from Tennessee, a former employee of a disc manufacturing and distribution company in Memphis. While working at the unnamed company between 2021 and 2022, Hale allegedly stole numerous "pre-release" DVD and Blu-ray discs from his employer. These stolen discs contained many high-profile movie titles including "Spider-Man: No Way Home." In addition to the copyright infringement charge, Hale was also indicted for a firearm offense. When raiding his premises, law enforcement found a gun in a car that was registered in his name, which, for a felon, is a separate criminal offense. Hale was sentenced at a federal court in Memphis yesterday, where Chief Judge Sheryl H. Lipman handed down a 57-month prison term, exactly in line with the U.S. government's recommendation. Two separate sentences will be served concurrently. Hale received 21 months for the theft and distribution of hundreds of pre-release movie discs. A longer sentence of 57 months was handed down for the firearm charge, which ultimately defines the total prison term. Judge Lipman also granted several requests by the defense. The court recommended that Hale be housed in a facility as close to Memphis as possible so he can be near his family. In addition, the defendant will be allowed to remain on bond and self-surrender to prison at a later date. The 21-month sentence for the copyright infringement charge is substantially lower than the maximum of 60 months. This is in part the result of a guilty plea the defendant signed in May. After accepting responsibility, the prosecution agreed to drop other charges and recommend a sentence at the low end of the guideline range. Hale entered his guilty plea to Count Two of the indictment. The charge relates to his distribution of ten or more copies of copyrighted works, including pre-release movies, for commercial advantage and private financial gain. This includes the pre-release 'Spider-Man: No Way Home' disc, which is likely the source of the public leak.
