Student-Built Rocket Breaks Multiple 20-Year Spaceflight Records

A team of undergraduate students from the University of Southern California's Rocket Propulsion Lab set multiple amateur spaceflight records with their rocket, Aftershock II. "The student-made missile soared 90,000 feet (27,400 meters) beyond the previous record-holder -- a rocket launched more than 20 years ago," reports Live Science. From the report: The students launched Aftershock II on Oct. 20 from a site in Black Rock Desert, Nevada. The rocket stood about 14 feet (4 meters) tall and weighed 330 pounds (150 kilograms). The rocket broke the sound barrier just two seconds after liftoff and reached its maximum speed roughly 19 seconds after launch, the RPL team wrote in a Nov. 14 paper summarizing the launch. The rocket's engine then burned out, but the craft continued to climb as atmospheric resistance decreased, enabling it to leave Earth's atmosphere 85 seconds after launch and then reach its highest elevation, or apogee, 92 seconds later. At this point, the nose cone separated from the rest of the rocket and deployed a parachute so it could safely reenter the atmosphere and touch down in the desert, where it was collected by the RPL team for analysis. The rocket's apogee was around 470,000 feet (143,300 m) above Earth's surface, which is "further into space than any non-governmental and non-commercial group has ever flown before," USC representatives wrote in a statement. The previous record of 380,000 feet (115,800 m) was set in 2004 by the GoFast rocket made by the Civilian Space Exploration Team. During the flight, Aftershock II reached a maximum speed of around 3,600 mph (5,800 km/h), or Mach 5.5 -- five and a half times the speed of sound. This was slightly faster than GoFast, which had also held the amateur speed record for 20 years. But elevation and speed were not the only records Aftershock II broke. "This achievement represents several engineering firsts," Ryan Kraemer, an undergraduate mechanical engineering student at USC and executive engineer of the RPL team who will soon join SpaceX's Starship team, said in the statement. "Aftershock II is distinguished by the most powerful solid-propellant motor ever fired by students and the most powerful composite case motor made by amateurs."

Remembering Cyberia, the World's First Ever Cyber Cafe

An anonymous reader quotes a report from VICE: It's early on a Sunday morning in late 1994, and you're shuffling your way through Fitzrovia in Central London, bloodstream still rushing after a long night at Bagley's. The sun comes up as you come down. You navigate side streets that you know like the back of your hand. But your hand's stamped with a party logo. And your brain's kaput. Coffee... yes, coffee. Good idea. Suddenly, you find yourself outside a teal blue cafe. Walking in is like entering an alien world; rows of club kids, tech heads, and game developers sit in front of desktops, lost in the primitive version of some new reality. Tentacular cables hang from the ceiling. Ambient techno reverberates from wall to wall. Cigarette smoke fills the air. Welcome to Cyberia, the world's first internet cafe. Which, if you're too young to remember, are basically cafes with computers in them. It all began when Eva Pascoe, a Polish computing student living in London, crossed paths with Tim Berners Lee and other early internet mavericks at the dawn of the 90s. "I was very interested in cyberfeminism and wanted to figure out how women could reclaim tech," she recalls. The internet was still in its infancy. Diabolically slow dial-up modems only emerged around 1992; the World Wide Web was a pipe dream until 1993 and hardly anyone had the internet at home. But there wasn't just a lack of javascript; Eva remembers there being no good java, either. "There were no coffee shops in London," she says, which today seems ludicrous. "Just greasy spoons and everyone drank tea. I wanted a European-style cafe." Linking up with like-minded pioneers David Rowe and husband and wife Keith and Gene Teare, Eva found a spot on the corner of Whitfield Street and launched Cyberia there in 1994. With Hackers-style aesthetics and futuristic furniture, it was based around a U-shaped layout that meant visitors could see each other's screens. "I wanted women to feel safe, because a lot of the stuff on the net was dodgy," she explains. Many of Eva's mates chipped in to help out -- architects, interior designers, graphic artists, publishers, and ravers among them. And then there was the Amish community in Pennsylvania. Eva had to fly out there to negotiate for the "Cyberia.com" domain name they had bought. "It was a proper barn with horse carts and a wall of modems as they were running a bulletin board and an early ecommerce company. Apparently, there was always one family nominated to be the tech support," she remembers. Back in London, Cyberia quickly became a hotspot. "Virtually the second we opened, we had three lines deep around the block," she says. It's hard to imagine, but nowhere else in the world was doing what they were doing. It was the world's first cybercafe. "If you wanted to collect your emails, we were the only place in town," Eva says. Cyberia opened around 20 cafes worldwide, including branches in Bangkok, Paris, and Rotterdam. "For a fleeting moment it became like a sexier version of Richard Branson's Virgin empire: there was Cyberia Records, Cyberia Channel (a pioneering streaming service), Cyberia Payments, the Cyberia magazine, a Cyberia show on UK TV -- even a Cyberia wedding," writes VICE's Kyle MacNeill. He attended Cyberia's 30th birthday party in September and spoke with some of the cafe's original innovators, "shooting the shit about the good times and the not-so-good coffee."

China Wiretaps Americans in 'Worst Hack in Our Nation's History'

Longtime Slashdot reader mspohr shares a report from Gizmodo: Hackers for the Chinese government were able to deeply penetrate U.S. telecommunications infrastructure in ways that President Joe Biden's administration hasn't yet acknowledged, according to new reports from the Washington Post and New York Times. The hackers were able to listen to phone calls and read text messages, reportedly exploiting the system U.S. authorities use to wiretap Americans in criminal cases. The worst part? The networks are still compromised and it may take incredibly drastic measures to boot them from U.S. systems. The hackers behind the infiltration of U.S. telecom infrastructure are known to Western intelligence agencies as Salt Typhoon, and this particular breach of U.S. equipment was first reported in early October by the Wall Street Journal. But Sen. Mark Warner, a Democrat from Virginia, spoke with the Washington Post and New York Times this week to warn the public that this is so much worse than we initially thought, dubbing it "the worst telecom hack in our nation's history." And those articles based on Warner's warnings were published late Thursday. Hackers weren't able to monitor or intercept anything encrypted, according to the Times, which means that conversations over apps like Signal and Apple's iMessage were probably protected. But end-to-end encryption over texts between Apple devices and Android devices, for instance, aren't encrypted in the same way, meaning they were vulnerable to interception by Salt Typhoon, according to the Times. The details about how the hackers were able to push so deeply into U.S. systems are still scarce, but it has something to do with the ways in which U.S. authorities wiretap suspects in this country with a court order.

Economist Makes the Case For Slow Level 1 EV Charging

Longtime Slashdot reader Geoffrey.landis writes: Economist Phillip Kobernick makes the case that the emphasis on fast-charging stations for electric vehicles in the U.S. is misplaced. According to an article from CleanTechnica, he argues that, from an economic standpoint, what we should be doing is installing more slow chargers. All thing equal, who wouldn't choose a 10-minute charge over a 3-hour charge or a 10-hour charge? But all things are not equal. Superfast chargers are far more expensive than Level 2 chargers, and Level 2 chargers are also significantly more expensive than Level 1 charging infrastructure, which consists of normal electricity outlets. He points out that we get 4-7 times more charging capability installed for the same cost by going with Level 1 charging instead of Level 2. And given that people often just plug in their electric vehicles overnight, Level 1 charging can more than adequately provide what is needed in that time. The case is examined in a podcast on the site.

Russian Spies Jumped From One Network To Another Via Wi-Fi

23 novembre 2024 à 00:45
"Steven Adair, of cybersecurity firm Veloxity, revealed at the Cyberwarcon security conference how Russian hackers were able to daisy-chain as many as three separate Wi-Fi networks in their efforts to attack victims," writes Longtime Slashdot reader smooth wombat. Wired reports: Adair says that Volexity first began investigating the breach of its DC customer's network in the first months of 2022, when the company saw signs of repeated intrusions into the customer's systems by hackers who had carefully covered their tracks. Volexity's analysts eventually traced the compromise to a hijacked user's account connecting to a Wi-Fi access point in a far end of the building, in a conference room with external-facing windows. Adair says he personally scoured the area looking for the source of that connection. "I went there to physically run down what it could be. We looked at smart TVs, looked for devices in closets. Is someone in the parking lot? Is it a printer?" he says. "We came up dry." Only after the next intrusion, when Volexity managed to get more complete logs of the hackers' traffic, did its analysts solve the mystery: The company found that the hijacked machine which the hackers were using to dig around in its customer's systems was leaking the name of the domain on which it was hosted -- in fact, the name of another organization just across the road. "At that point, it was 100 percent clear where it was coming from," Adair says. "It's not a car in the street. It's the building next door." With the cooperation of that neighbor, Volexity investigated that second organization's network and found that a certain laptop was the source of the street-jumping Wi-Fi intrusion. The hackers had penetrated that device, which was plugged into a dock connected to the local network via Ethernet, and then switched on its Wi-Fi, allowing it to act as a radio-based relay into the target network. Volexity found that, to break into that target's Wi-Fi, the hackers had used credentials they'd somehow obtained online but had apparently been unable to exploit elsewhere, likely due to two-factor authentication. Volexity eventually tracked the hackers on that second network to two possible points of intrusion. The hackers appeared to have compromised a VPN appliance owned by the other organization. But they had also broken into the organization's Wi-Fi from another network's devices in the same building, suggesting that the hackers may have daisy-chained as many as three networks via Wi-Fi to reach their final target. "Who knows how many devices or networks they compromised and were doing this on," says Adair. Volexity had presumed early on in its investigation that the hackers were Russian in origin due to their targeting of individual staffers at the customer organization focused on Ukraine. Then in April, fully two years after the original intrusion, Microsoft warned of a vulnerability in Windows' print spooler that had been used by Russia's APT28 hacker group -- Microsoft refers to the group as Forest Blizzard -- to gain administrative privileges on target machines. Remnants left behind on the very first computer Volexity had analyzed in the Wi-Fi-based breach of its customer exactly matched that technique. "It was an exact one-to-one match," Adair says.

Google Sues Ex-Engineer In Texas Over Leaked Pixel Chip Secrets

An anonymous reader quotes a report from Reuters: Google has sued one of its former engineers in Texas federal court, accusing him of stealing trade secrets related to its chip designs and sharing them publicly on the internet. The lawsuit, filed on Tuesday (PDF), said that Harshit Roy "touted his dominion" over the secrets in social media posts, tagging competitors and making threatening statements to the company including "I need to take unethical means to get what I am entitled to" and "remember that empires fall and so will you." Google hired Roy in 2020 to develop computer chips used in Google Pixel devices like smartphones. Google said in the lawsuit that Roy resigned in February and moved from Bangalore, India to the United States in August to attend a doctorate program at the University of Texas at Austin. According to the complaint, Roy began posting confidential Google information to his X account later that month along with "subversive text" directed at the company, such as "don't expect me to adhere to any confidentiality agreement." The posts included photographs of internal Google documents with specifications for Pixel processing chips. The lawsuit said that Roy ignored Google's takedown requests and has posted additional trade secrets to X and LinkedIn since October. Google alleged that Roy tagged competitors Apple and Qualcomm in some of the posts, "presumably to maximize the potential harm of his disclosure." Google's complaint also said that several news outlets have published stories with confidential details about Google's devices based on the information that Roy leaked. Google asked the court for an unspecified amount of monetary damages and court orders blocking Roy from using or sharing its secrets.

Steam Cuts the Cord For Legacy Windows, macOS

The latest Steam client drops support for operating systems older than Windows 10 or macOS 10.15 Catalina. "That means Mac users can't run 32-bit games anymore, as all macOS versions from Catalina onward only run 64-bit binaries," reports The Register. From the report: [I]f you have a well-specified older Mac, here is another reason to check out Open Core Legacy Patcher. For now, macOS 10.15 Catalina will do but we suspect it won't for long. This version of Steam uses the equivalent to Chrome 126: "Updated embedded Chromium build in Steam to 126.0.6478.183." However, versions since Chrome 128 require macOS 11 or newer. For now, Catalina will work -- but the next significant Steam update will update Chromium as well, and there's a high probability that that will drop support for 10.15. So, if you're using OCLP to install a newer macOS, you should probably go directly to Big Sur. In The Reg FOSS desk's testing, we found that Big Sur ran reasonably well on a machine with Intel HD 520 graphics, although the same hardware ran very poorly with macOS 12 Monterey. Unfortunately, the inevitable end is in sight for older Macs. That said, the November 2024 Steam client update brings several "wins," including a built-in Game Recording feature, an upgraded Chromium browser engine, and the new "Scout" Linux runtime environment for improved compatibility and performance, especially on the Steam Deck and Linux distros. Additionally, it delivers bug fixes and enhancements for modern OS users.

Baidu's Supercheap Robotaxis Should Scare the Hell Out of the US

Baidu's new Apollo Go robotaxi brings significant advances in affordability and scalability that should make U.S. competitors like Waymo a bit nervous, according to The Verge's Andrew J. Hawkins. From the report: The RT6 is the sixth generation of Apollo Go's driverless vehicle, which made its official debut in May 2024. It's a purpose-built, Level 4 autonomous vehicle, meaning it's built without the need for a human driver. And here's the thing that should make US competitors nervous: adopting a battery-swapping solution, the price for one individual RT6 is "under $30,000," Baidu CEO Robin Li said in an earnings call. "All the strengths just mentioned above are driving us forward, paving the way to validate our business model," Li added. [...] We still don't know the net effect of Baidu's cost improvements. But bringing down the upfront cost of each individual vehicle to below $30,000 will go a long way toward improving the company's unit economics, in which each vehicle brings in more money than it costs. There are still a lot of outstanding costs to consider, such as hardware depreciation and fleet maintenance, but from what Baidu is signaling, things are on the right track. From the looks of it, the company is passing those savings along to its customers. Base fares start as low as 4 yuan (around 55 cents), compared with 18 yuan (around $2.48) for a taxi driven by a human, according to state media outlet Global Times. Apollo Go said it has provided 988,000 rides across all of China in Q3 2024 -- a year-over-year growth of 20 percent. And cumulative public rides reached 8 million in October.

DirecTV Terminates Deal To Buy Dish Satellite Business

An anonymous reader quotes a report from Ars Technica: DirecTV is pulling out of an agreement to buy its satellite rival Dish after bondholders objected to terms of the deal. DirecTV issued an announcement last night saying "it has notified EchoStar of its election to terminate, effective as of 11:59 p.m., ET on Friday, November 22nd, 2024, the Equity Purchase Agreement (EPA) pursuant to which it had agreed to acquire EchoStar's video distribution business, Dish DBS." In the deal announced on September 30, DirecTV was going to buy the Dish satellite TV and Sling TV streaming business from EchoStar for a nominal fee of $1. DirecTV would have taken on $9.75 billion of Dish debt if the transaction moved ahead. The deal did not include the Dish Network cellular business. Dish bondholders quickly objected to terms requiring them to take a loss on the value of their debt. DirecTV had said Dish notes would be exchanged with "a reduced principal amount of DirecTV debt which will have terms and collateral that mirror DirecTV's existing secured debt." The principal amount would have been reduced by at least $1.568 billion. DirecTV last night said it is now exercising its right to terminate the acquisition because noteholders did not accept the exchange offer. "The termination of the Agreement follows Dish DBS noteholders' failure to agree to the proposed Exchange Debt Offer Terms issued by EchoStar, which was a condition of DirecTV's obligations to acquire Dish under the EPA," the press release said. DirecTV CEO Bill Morrow indicated his company wasn't willing to change the deal to satisfy Dish bondholders. "We have terminated the transaction because the proposed Exchange Terms were necessary to protect DirecTV's balance sheet and our operational flexibility," Morrow said.

Un an après avoir investi 4 milliards de dollars dans Anthropic, Amazon double la mise : la société vient en effet d’annoncer qu’elle allait apporter 4 milliards de dollars de fonds supplémentaires à cette startup spécialisée dans l’IA, éditrice des grands modèles de langage Claude. En dépit de ces 8 milliards de dollars d’investissement, Amazon reste à ce stade un actionnaire minoritaire d’Anthropic, prend soin de préciser la startup.

Cet apport d’argent frais intervient dans le cadre d’un partenariat plus global entre les deux entreprises qui fait d’AWS, la division cloud d’Amazon, le principal partenaire d’Anthropic en matière d’infrastructures, qu’il s’agisse de faire tourner les modèles au quotidien ou de les entraîner.

Anthropic indique par ailleurs renforcer sa collaboration avec les Annapurna Labs d’AWS, l’entité chargée de développer les accélérateurs Trainium dédiés à l’IA, dont la deuxième génération avait été présentée fin 2023 par Amazon. « Grâce à une collaboration technique approfondie, nous écrivons des noyaux de bas niveau qui nous permettent d’interagir directement avec le silicium Trainium et de contribuer à la pile logicielle AWS Neuron pour renforcer Trainium », écrit Anthropic.

Soutenue par Amazon, mais aussi par Google (2 milliards de dollars investis à l’automne 2023), Anthropic se positionne comme la grande rivale d’OpenAI sur le marché en plein essor de l’intelligence artificielle générative. Début septembre, l’entreprise a par exemple lancé une offre baptisée Claude for Enterprise, qui concurrence directement la formule dédiée aux grands comptes de ChatGPT.

Northvolt : le fabricant suédois de batteries se déclare en faillite

Northvolt : le fabricant suédois de batteries se déclare en faillite

Le fabricant de batteries électriques suédois aux ambitions européennes a demandé sa mise sous protection du chapitre 11 de la loi sur les faillites américaines. Il espère pouvoir se relever grâce à cette procédure, mais il semble que Northvolt ait perdu la confiance des groupes automobiles comme Volvo ou BMW.

Sale temps pour l’industrie des batteries en Europe. L’annonce par Northvolt de sa demande d’être mise sous la protection du chapitre 11 de la loi sur les faillites des États-Unis, publiée dans la nuit de jeudi 21 à vendredi 22 novembre en est réellement un symbole.

L’entreprise européenne a pu profiter de cette disposition américaine, car elle a quelques activités en Californie. Néanmoins, ses activités sont principalement concentrées en Europe, notamment avec son usine historique de Skellefteå au nord de la Suède.

Son PDG, Peter Carlsson, a, dans la foulée, démissionné de son poste tout en restant au sein de l’entreprise, devenant un conseiller « senior ». Northvolt avait pourtant comme ambition d’être le meneur de l’industrie européenne des batteries.

Northvolt était pourtant encore qualifiée en juin dernier par Bloomberg de « plus grand et le plus prometteur fabricant de batteries du continent ».

Promesses de restructurer sa dette

Le président intérimaire du conseil d’administration, Tom Johnstone, veut rassurer en expliquant que « cette étape décisive permettra à Northvolt de poursuivre sa mission d’établir une base industrielle européenne pour la production de batteries […] Malgré les défis à court terme, cette action visant à renforcer notre structure de capital nous permettra de répondre à la demande continue du marché pour l’électrification des véhicules. Nous sommes également satisfaits du fort soutien que nous avons reçu de la part de nos prêteurs existants et de nos clients ».

L’entreprise promet que cette procédure va lui permettre de « restructurer sa dette, d’adapter son activité aux besoins actuels de ses clients et d’assurer une base durable pour la poursuite de ses activités ». Elle explique que ce redressement judiciaire va lui permettre d’avoir accès à 145 millions de dollars (139 millions d’euros) de trésorerie qui peuvent l’aider à retomber sur ses pieds.

Elle ajoute qu’elle va continuer à « effectuer des livraisons à ses clients, tout en remplissant ses obligations envers les fournisseurs essentiels et en payant les salaires de ses employés ».

Suppression d’emplois et impayés de 41 millions d’euros

Rappelons que l’entreprise a annoncé la suppression de 1 600 emplois en septembre dernier (un quart de ses effectifs mondiaux). Elle avait aussi expliqué qu’elle suspendait de nouveaux projets dans son usine historique.

Début novembre, le média suédois Nu.se expliquait que les autorités suédoises étaient saisies par plusieurs entreprises pour des impayés de Northvolt dont le montant total atteignait les 474 millions de couronnes suédoises (41 millions d’euros).

Perte de confiance

L’entreprise, fondée par deux anciens salariés de Tesla, a pour principaux actionnaires Volkswagen et BMW. Scania ou encore Volvo ont participé aux différentes levées de fonds depuis sa création.

Mais les relations avec ces constructeurs deviennent tendues. Volvo a, par exemple, annoncé le 30 octobre dernier sa volonté de racheter les parts de Northvolt dans la coentreprise NOVO Energie qu’elles avaient créée récemment pour la construction d’une usine de cellules de batteries à Göteborg. BMW avait aussi précédemment annulé une commande de 2 milliards d’euros en juin dernier.

Symbole des difficultés européennes

Les difficultés de Northvolt symbolisent bien celles du secteur entier en Europe. ACC, la coentreprise entre Stellantis, Mercedes et TotalEnergies a annoncé aux Echos que son site de Billy-Berclau devrait avoir produit en 2024 entre 2 000 et 4 000 packs de batteries. « C‘est beaucoup moins que ce que nous envisagions en début d’année », expliquait à nos confrères le PDG Yann Vincent.

Pendant ce temps-là, le chinois CATL cherche à faire de l’Europe son sous-traitant de batteries, comme l’expliquait Challenges en début d’année, en installant des usines au Portugal ou en Allemagne, par exemple.

Le plus grand fabricant mondial de batteries pour véhicules électriques est actuellement en discussion avec les autorités européennes, annonçait récemment Bloomberg, pour installer des usines de recyclage de batteries sur le sol européen ainsi qu’une usine de production de cellules en Hongrie qui pourrait ouvrir dans la deuxième moitié de l’année 2025.
