Aujourd'hui, si tu veux une carte graphique Gamer, dans certaines boutiques, c'est 1829 euros minimum

Par : mantidor@cowcotland.com (Aurélien LAGNY)
Franchement, on a envie de redire : Non mais allo, tu es un Gamer et tu n'as pas de carte graphique ? En même temps, il est clairement très difficile de s'offrir une carte graphique Gaming ces derniers temps. Nous venons de faire notre tour des tarifs et notre tour des disponibilités et le constat est effarant ce jour. En effet, si vous regardez chez le groupe LDLC, il n'y a aucune carte graphique d'entrée de gamme ou milieu de gamme disponible. La première carte Gamer disponible à l'achat est une Gigabyte Radeon RX 6900 XT GAMING OC et son prix est OUF, nous sommes à 1829 euros.

Et si la NVIDIA GeForce RTX 2060 12 Go n'était en fait qu'une carte de Mining ???

Par : mantidor@cowcotland.com (Aurélien LAGNY)
C'est le très vérace Moore's Law is Dead qui explique cela. Selon plusieurs de ses sources, la nouvelle carte graphique des verts pourrait, ( vous notez bien que c'est du conditionnel ), avoir une autre fonction qu'une carte pour les joueurs. En effet, cette carte pourrait être en réalité une carte à destination du Mining, ce qui expliquerait aussi sa grosse quantité de mémoire vidéo. Cette carte, contrairement à d'autres modèles CMP, propose une panoplie complète de sorties et donc elle aura plus de valeur à la revente que les cartes dédiées au Mining qui sont difficiles à refourguer une fois qu'elles sont en fin de carrière. etnbsp;

Mysterious Galaxy Without Dark Matter Puzzles Astronomers

Astronomers say they've located six galaxies that appear to have either very little or absolutely no dark matter. The team will present its findings in Monthly Notices of the Royal Astronomical Society. CNET reports: Mentioning that they'd previously been told "measure again, you'll see there will be dark matter around your galaxy," the researchers zeroed in on one seemingly dark-matter-free region dubbed AGC 114905 to strengthen their evidence. Lurking 250 million light-years away from Earth, it's about the size of the Milky Way, with a thousand times fewer stars. So it's rather dim. The researchers used a standard technique to detect the presence of dark matter in AGC 114905 that involves graphing the position and rotation speed of the galaxy's gas. After 40 hours of scrutiny with the high-powered Very Large Array Radio Telescope in New Mexico, they found the movements of the gas were perfectly explainable by normal matter alone. "The problem remains that the theory predicts that there must be dark matter in AGC 114905," Pavel Mancera Piñabut of the Kapteyn Astronomical Institute at the University of Groningenour and an author of the study, said in a statement, referring to classic dark matter hypotheses. "Observations say there isn't -- in fact, the difference between theory and observation is only getting bigger." One caveat, the team says, is that perhaps the angle at which they viewed AGC 114905 affected their observational results. "But that angle has to deviate very much from our estimate before there is room for dark matter again," Tom Oosterloo of Astron at the Netherlands Institute for Radio Astronomy and co-author of the study, said in a statement. And if they're correct? The team offers up a few reasons for why AGC 114905 may not have any dark matter. For instance, what if super large galaxies nearby somehow stripped it of the force? As a rebuttal, though, Mancera Pinabut says there don't seem to be any such galaxies in the vicinity. Further, he says, "in the most reputed galaxy formation framework, the so-called cold dark matter model, we would have to introduce extreme parameter values that are far beyond the usual range. Also with modified Newtonian dynamics, an alternative theory to cold dark matter, we cannot reproduce the motions of the gas within the galaxy."

SolarWinds Hackers Have a Whole Bag of New Tricks For Mass Compromise Attacks

An anonymous reader quotes a report from Ars Technica: Almost exactly a year ago, security researchers uncovered one of the worst data breaches in modern history, if not ever: a Kremlin-backed hacking campaign that compromised the servers of network management provider SolarWinds and, from there, the networks of 100 of its highest-profile customers, including nine US federal agencies. Nobelium -- the name Microsoft gave to the intruders -- was eventually expelled, but the group never gave up and arguably has only become more brazen and adept at hacking large numbers of targets in a single stroke. The latest reminder of the group's proficiency comes from security firm Mandiant, which on Monday published research detailing Nobelium's numerous feats -- and a few mistakes -- as it continued to breach the networks of some of its highest-value targets. Mandiant's report shows that Nobelium's ingenuity hasn't wavered. Since last year, company researchers say the two hacking groups linked to the SolarWinds hack -- one called UNC3004 and the other UNC2652 -- have continued to devise new ways to compromise large numbers of targets in an efficient manner. Instead of poisoning the supply chain of SolarWinds, the groups compromised the networks of cloud solution providers and managed service providers, or CSPs, which are outsourced third-party companies that many large companies rely on for a wide range of IT services. The hackers then found clever ways to use those compromised providers to intrude upon their customers. The advanced tradecraft didn't stop there. According to Mandiant, other advanced tactics and ingenuities included: Use of credentials stolen by financially motivated hackers using malware such as Cryptbot (PDF), an information stealer that harvests system and web browser credentials and cryptocurrency wallets. The assistance from these hackers allowed the UNC3004 and UNC2652 to compromise targets even when they didn't use a hacked service provider.Once the hacker groups were inside a network, they compromised enterprise spam filters or other software with "application impersonation privileges," which have the ability to access email or other types of data from any other account in the compromised network. Hacking this single account saved the hassle of having to break into each account individually.The abuse of legitimate residential proxy services or geo-located cloud providers such as Azure to connect to end targets. When admins of the hacked companies reviewed access logs, they saw connections coming from local ISPs with good reputations or cloud providers that were in the same geography as the companies. This helped disguise the intrusions, since nation-sponsored hackers frequently use dedicated IP addresses that arouse suspicions.Clever ways to bypass security restrictions, such as extracting virtual machines to determine internal routing configurations of the networks they wanted to hack.Gaining access to an active directory stored in a target's Azure account and using this all-powerful administration tool to steal cryptographic keys that would generate tokens that could bypass two-factor authentication protections. This technique gave the intruders what's known as a Golden SAML, which is akin to a skeleton key that unlocks every service that uses the Security Assertion Markup Language, which is the protocol that makes single sign-on, 2FA, and other security mechanisms work.Use of a custom downloader dubbed Ceeloader.

China 'Modified' the Weather To Create Clear Skies For Political Celebration, Study Finds

Chinese weather authorities successfully controlled the weather ahead of a major political celebration earlier this year, according to a Beijing university study. The Guardian reports: On 1 July the Chinese Communist party marked its centenary with major celebrations including tens of thousands of people at a ceremony in Tiananmen Square, and a research paper from Tsinghua University has said an extensive cloud-seeding operation in the hours prior ensured clear skies and low air pollution. [...] On Monday the South China Morning Post reported a recent research paper which found definitive signs that a cloud-seeding operation on the eve of the centenary had produced a marked drop in air pollution. The centenary celebration faced what the paper reportedly termed unprecedented challenges, including an unexpected increase in air pollutants and an overcast sky during one of the wettest summers on record. Factories and other polluting activities had been halted in the days ahead of the event but low airflow meant the pollution hadn't dissipated, it said. The paper, published in the peer-reviewed Environmental Science journal and led by environmental science professor, Wang Can, said a two-hour cloud-seeding operation was launched on the eve of the ceremony, and residents in nearby mountain regions reported seeing rockets shot into the sky on 30 June. The paper said the rockets were carrying silver iodine into the sky to stimulate rainfall. The researchers said the resulting artificial rain reduced the level of PM2.5 air pollutants by more than two-thirds, and shifted the air quality index reading, based on World Health Organization standards, from "moderate" to "good." The team said the artificial rain "was the only disruptive event in this period," so it was unlikely the drop in pollution had a natural cause.

DeepMind Cracks 'Knot' Conjecture That Bedeviled Mathematicians For Decades

The artificial intelligence (AI) program DeepMind has gotten closer to proving a math conjecture that's bedeviled mathematicians for decades and revealed another new conjecture that may unravel how mathematicians understand knots. Live Science reports: The two pure math conjectures are the first-ever important advances in pure mathematics (or math not directly linked to any non-math application) generated by artificial intelligence, the researchers reported Dec. 1 in the journal Nature. [...] The first challenge was setting DeepMind onto a useful path. [...] They focused on two fields: knot theory, which is the mathematical study of knots; and representation theory, which is a field that focuses on abstract algebraic structures, such as rings and lattices, and relates those abstract structures to linear algebraic equations, or the familiar equations with Xs, Ys, pluses and minuses that might be found in a high-school math class. In understanding knots, mathematicians rely on something called invariants, which are algebraic, geometric or numerical quantities that are the same. In this case, they looked at invariants that were the same in equivalent knots; equivalence can be defined in several ways, but knots can be considered equivalent if you can distort one into another without breaking the knot. Geometric invariants are essentially measurements of a knot's overall shape, whereas algebraic invariants describe how the knots twist in and around each other. "Up until now, there was no proven connection between those two things," [said Alex Davies, a machine-learning specialist at DeepMind and one of the authors of the new paper], referring to geometric and algebraic invariants. But mathematicians thought there might be some kind of relationship between the two, so the researchers decided to use DeepMind to find it. With the help of the AI program, they were able to identify a new geometric measurement, which they dubbed the "natural slope" of a knot. This measurement was mathematically related to a known algebraic invariant called the signature, which describes certain surfaces on knots. In the second case, DeepMind took a conjecture generated by mathematicians in the late 1970s and helped reveal why that conjecture works. For 40 years, mathematicians have conjectured that it's possible to look at a specific kind of very complex, multidimensional graph and figure out a particular kind of equation to represent it. But they haven't quite worked out how to do it. Now, DeepMind has come closer by linking specific features of the graphs to predictions about these equations, which are called Kazhdan-Lusztig (KL) polynomials, named after the mathematicians who first proposed them. "What we were able to do is train some machine-learning models that were able to predict what the polynomial was, very accurately, from the graph," Davies said. The team also analyzed what features of the graph DeepMind was using to make those predictions, which got them closer to a general rule about how the two map to each other. This means DeepMind has made significant progress on solving this conjecture, known as the combinatorial invariance conjecture.

Eurostar Tests Facial Recognition System On London Train Station

An anonymous reader quotes a report from BleepingComputer: Eurostar is testing a new biometric facial recognition technology on passengers traveling from London's St Pancras International station to continental Europe. The passengers will be given the opportunity to complete their pre-departure ticket and passport checks via the new biometric system, called the "SmartCheck" lane. Those who take this option will be allowed to board the train without going through the typically tedious ID verification procedures. The system will involve two facial scans, one at the ticket gate to verify the ticket check and one at the UK Exit Checkpoint, to confirm that the passport information is valid. The goal, according to Eurostar, is to eliminate queues and expedite the boarding process, not only improving customer satisfaction but also minimizing the chances for viral transmission. The system will be trialed with a limited number of invited passengers and won't involve the UK's or Schengen entry controls. Eurostar announced its intention to introduce a facial recognition system to replace physical tickets and passport checks last year, and facial recognition company iProov helped them build it. iProov is a proponent of what they call "passive authentication", which is facial recognition without the user having to do anything. The user consents to the platform by visiting an online portal to register with their information and takes an image of their face with the smartphone or webcam. When they reach a physical checkpoint, they simply look at the camera, and the system authenticates them effortlessly.

Verizon Might Be Collecting Your Browsing History

Verizon might be collecting information about your browsing history, location, apps, and your contacts, all in the name of helping the company "understand your interests," first spotted by Input. The Verge reports: The program, which Verizon appears to automatically opt customers into, is called Verizon Custom Experience and its controls lay buried in the privacy settings on the My Verizon app. The program introduces two different options that appear in the app, Custom Experience and Custom Experience Plus, each of which varies in terms of invasiveness. Verizon provides additional information about both settings within the app, as well as on a FAQ page on its website. It appears that the Custom Experience option is a stripped-down version of Custom Experience Plus, and as Verizon states directly in the app, it helps Verizon "personalize" its "communication with you" and "give you more relevant product and service recommendations" by using "information about websites you visit and apps you use on your mobile device." Meanwhile, Custom Experience Plus has the same stated purpose -- to help Verizon provide you with a more "personalized" experience. However, it not only uses information about the websites and apps you use on your mobile device, but it also says it uses your "device location," along with "phone numbers you call or that call you" to help Verizon "better understand your interests." This also includes your CPNI, which tracks the times and duration of your calls, and because Verizon is your wireless network provider, it can track your location even if you've turned off location services on your phone. As Verizon explains on its site, it might use your information to, say, present you with an offer that includes music content, or give you a music-related option in its Verizon Up reward program if it knows you like music. Verizon explicitly states that for the more invasive Customer Experience Plus tracking, you "must opt-in to participate and you can change your choice at any time." Signing up for those Up Rewards, or other promotions with consequences buried in the fine print may have opted customers in unknowingly. How to opt-out: "[...] open your My Verizon app, and then hit the gear icon in the top-right corner of the screen. Scroll down and select 'Manage privacy settings' beneath the 'Preferences' heading. On the next page, toggle off 'Custom Experience' and 'Custom Experience Plus.' To erase the information that Verizon has already collected about you through the program, tap 'Custom Experience Settings,' and hit 'Reset.'"

Toyota Plans $1.29 Billion Electric Vehicle Battery Factory In North Carolina

Toyota will open a multi-billion dollar battery plant with at least 1,750 employees about an hour's drive outside the Triangle, after North Carolina approved an incentive package Monday worth $438.7 million for the company -- one of the largest manufacturing investments in the state's history. From the News & Observer: The Japanese auto maker announced in October it would build a $1.29 billion facility in the United States to manufacture hybrid and electric vehicle batteries -- a key component of the company's plans to make 70% of its cars electric by the end of the decade. The plant known as Toyota Battery Manufacturing, North Carolina will be built in Liberty, a small town in Randolph County that is home to the Greensboro-Randolph Megasite, one of the designated areas in North Carolina the state markets to potential large manufacturers. Toyota will launch production in 2025 and expand operations by 2031. The site will produce 1.2 million battery packs per year, said Chris Reynolds, chief administrative officer of corporate resources for Toyota North America. The state's Economic Investment Committee approved the state's incentive for Toyota -- referred to internally as Project Darwin -- at a special meeting in Raleigh on Monday. The state's contribution is just one part of an incentive package from numerous entities that could reach $271.4 million. Reynolds did not have a timeline for when construction of the plant would begin but that it would be operational in 2025. Toyota eventually will create 1,750 jobs into 2029, with the jobs paying a minimum average wage of $62,234, according to the state's Commerce Department.
