un mini-récit raide de Flock pour Next

Hola, belle âme perdue qui est venue cliquer ici alors que tout pousse à faire autre chose que lire sur une quelconque dalle vitrée : Bienvenue !

Tu es ici pour t’élever, j’imagine. Tu as frappé à la bonne porte. Flock a philosophé devant les frugales colonnes de l’actualité des jours sans, il a même philosophé tellement fort qu’il est un peu claqué du bulbe. Du coup, il file au sofa jusqu’à la semaine prochaine.

Bon weekend à tous !

Après un MP600 Elite dont Matt vous narrait la naissance début février dernier, Corsair remet le couvert avec un Corsair MP700 PRO SE, qu’il ne faut pas confondre avec le MP700 tout court, ni le MP700 PRO, ni le MP600 PRO XT ! Bref, pas facile de s’y retrouver, mais voici quelque clefs : les MP700 s...

An anonymous reader quotes a report from Ars Technica: There's a fundamental flaw in current car safety tech: It's limited to line of sight. Or, perhaps, line of "sensing" is more accurate, because the way cameras and lidar work is to inspect the perimeter of a vehicle and use predictive algorithms to understand the motion of an object in relation to the motion of the vehicle itself. Which is good, because as carmakers have added elements such as pedestrian and cyclist detection, they're trying to prevent drivers from hurting the most vulnerable road users. And unfortunately this is necessary, because even though 2023 saw a slight reduction in drivers striking cyclists and pedestrians, according to the most recent data from the Governor's Highway Safety Association, since 2019 pedestrian fatalities are still up 14 percent -- and cyclist deaths are up 50 percent since 2010. That doesn't mean lidar and cameras have "failed," but because they rely on what the sensors can pick up, they cannot necessarily ID hazards (and alert drivers) as quickly as we need them to, particularly if that's a cyclist in your lane 300 feet down the road, just over the next rise. Yes, current sensing works well now with figuring out the pace of a traffic jam, and automatic emergency braking can step in to stop your car if you fail to. But for non-automotive obstacles, they're still limited. For that, we need better tech, which is emerging and is called Connected Vehicle to Everything (C-V2X). The idea isn't that complicated. Boiled down, it's a chipset that operates on a portion of the cellular bandwidth, and vehicles with this tech embedded (say in an e-bike or car) monitor anything with a C-V2X chip as well as broadcast their own location at a pulse of 10 times a second. This precision location system would then warn a driver of a cyclist on the road ahead, even beyond line of sight, and in an emergency -- possibly because a cyclist was right in a car's path -- could prevent a collision. [W]ith C-V2X, you don't need Verizon or ATT or anything like that," explains Audi's Kamal Kapadia. Because it isn't using the cellular network -- it's using a portion of cellular bandwidth to allow direct object, or vehicle-to-vehicle, communication. Audi has been working on C-V2X for nearly a decade, and it's part of a group in the US called the Coalition for Cyclist Safety, which also includes suppliers like Bosch, a tech startup in the space called Spoke Safety, and bike brands such as massive Trek, parts supplier Shimano, more niche bikemakers like Switzerland's Stromer, as well as mega telco suppliers and networks such as Qualcomm, Deutsche Telekom, and TELUS. [...] Mio Suzuki is Trek Bicycle's director of embedded systems, "and we are exploring all sorts of safety," she says. For instance, Trek recently introduced its own radar tail light, which warns riders of a car approaching rapidly -- Garmin has had similar systems for several years. But Suzuki is intrigued by C-V2X because it offers more advanced warning than rear-facing radar. "And unlike cars, we have a very vulnerable road user so we need to augment our senses and the rider's awareness of the riding environment, because we don't have a big metal shield around us." What Suzuki envisions this direct communication might enable is an e-bike where the rider has a display that would warn a rider "of an imminent danger that's approaching; a car might be coming from the side, but the view of the car is obstructed by a building, so the rider can't see." Franz Reindl is CTO of Stromer, a high-end Swiss brand that only makes e-bikes with very top tech, including ABS brakes. Reindl says they're also studying C-V2X. "Safety is one of our biggest promises, and we need to do everything we can with products and technologies to make it more safe for customers." Right now, only Audi and the VW Group have openly talked about using the tech. "Trek's Suzuki thinks that together, the Coalition and so many bike brands within it do have a strong voice," reports Ars. "She also envisions municipalities deploying the technology, especially around work crews and EMS, which should build broader momentum and pressure on automakers."

The Russia-linked ransomware group Black Basta is responsible for Wednesday's cyberattack on St. Louis-based Ascension health system, according to sources reported by CNN. The attack disrupted access to electronic health records, some phone systems and "various systems utilized to order certain tests, procedures and medications," the company said in a statement. From a report: On Friday, the nonprofit group Health-ISAC (Information Sharing and Analysis Center) issued an alert about the group, saying that Black Basta has "recently accelerated attacks against the healthcare sector." HHS said that Black Basta was initially spotted in early 2022, known for its double extortion attack. The group not only executes ransomware but also exfiltrates sensitive data, operating a cybercrime marketplace to publicly release it should a victim fail to pay a ransom. "The level of sophistication by its proficient ransomware operators, and reluctance to recruit or advertise on Dark Web forums, supports why many suspect the nascent Black Basta may even be a rebrand of the Russian-speaking RaaS threat group Conti, or also linked to other Russian-speaking cyber threat groups," the alert from HHS said. According to one report from blockchain analytics firm Elliptic and cybersecurity risk-focused Corvus Insurance, Black Basta in less than two years has won itself more than $100 million via ransomware schemes from 329 organizations. Previous victims of its attacks include Dish Network, the American Dental Association, business process services firm Capita and tech firm ABB.

Prévue pour le tout début du mois de Juin, la ROG Ally X serait plus une version améliorée de la machine actuelle qu’une véritable révolution. Beaucoup des éléments principaux de l’offre ne bougeraient pas mais des mises à jour techniques et logicielles devraient être proposées.

Ainsi la puce embarquée ne serait pas modifiée, faute d’un successeur viable  aux Ryzen Z1 et Z1 Extreme proposé par AMD. On resterait donc sur des capacités de calcul identiques même si la mémoire vive pourrait gagner en capacités. Pour le moment disponible en 16 Go maximum, la nouvelle pourrait donc choisir de basculer vers des versions 32 Go. Même évolutions possible pour le stockage qui resterait un NVMe PCIe mais qui pourrait évoluer vers une solution plus « classique ». En l’occurrence un stockage M.2 2280 qui offrirait plus de choix pour AMD comme pour les utilisateurs.

Autre point qui ne devrait pas changer, l’affichage qui serait identique avec un écran de 7″ de diagonale, toujours en IPS et 120 Hz. On parle également de modifications de batterie pour obtenir une meilleure autonomie ce qui aurait un impact sur le poids de l’engin. Diverses améliorations notamment pour les contrôles et divers réglages des soucis relevés par les premières versions seraient également prévues, à commencer par un déplacement du lecteur de cartes MicroSDXC qui avait connu des soucis de chauffe.

Enfin, et c’est peut être le mouvement principal, Asus semble avoir énormément travaillé sur sa suite logicielle avec une mise à jour majeure. Armor Crate, c’est son nom, serait amélioré pour rendre l’usage de la console plus efficace et moins dépendant de l’interface de Windows. Un changement important qui impacterait non seulement ce modèle Asus ROG Ally X mais également les consoles actuelles avec une mise à jour globale.

Pas de détail précis sur le tarif de la nouvelle version mais un probable repositionnement plus haut de gamme correspondant aux prix d’origine de la console à sa sortie.

Des produits avec des styles, disons, futuristes, on en connait quelques uns. Et aujourd'hui, nous en découvrons un nouveau avec un petit teaser organisé par ACEMAGIC : le M2A STARSHIP, un Mini PC qui ira à merveille avec un routeur Netgear par exemple. On optant pour un design de ce genre, ACEMAGIC réfléchit son système de refroidissement : les ailes inférieures surélèvent le PC pour que les deux ventilateurs de la partie principale puissent respirer convenablement et évacuer la chaleur transportée par les sept caloducs ; signe que la configuration est puissante. Enfin, les ailes supérieures ont également des ventilateurs, certainement pour apporter de l'air à la partie centrale. […]

A tokamak in France achieved a new record in fusion plasma by using tungsten to encase its reaction, which enabled the sustainment of hotter and denser plasma for longer periods than previous carbon-based designs. Quartz reports: A tokamak is a torus- (doughnut-) shaped fusion device that confines plasma using magnetic fields, allowing scientists to fiddle with the superheated material and induce fusion reactions. The recent achievement was made in WEST (tungsten (W) Environment in Steady-state Tokamak), a tokamak operated by the French Alternative Energies and Atomic Energy Commission (CEA). WEST was injected with 1.15 gigajoules of power and sustained a plasma of about 50 million degrees Celsius for six minutes. It achieved this record after scientists encased the tokamak's interior in tungsten, a metal with an extraordinarily high melting point. Researchers from Princeton Plasma Physics Laboratory used an X-ray detector inside the tokamak to measure aspects of the plasma and the conditions that made it possible. "These are beautiful results," said Xavier Litaudon, a scientist with CEA and chair of the Coordination on International Challenges on Long duration OPeration (CICLOP), in a PPPL release. "We have reached a stationary regime despite being in a challenging environment due to this tungsten wall."

An anonymous reader quotes a report from The Guardian: A British toddler has had her hearing restored after becoming the first person in the world to take part in a pioneering gene therapy trial, in a development that doctors say marks a new era in treating deafness. Opal Sandy was born unable to hear anything due to auditory neuropathy, a condition that disrupts nerve impulses traveling from the inner ear to the brain and can be caused by a faulty gene. But after receiving an infusion containing a working copy of the gene during groundbreaking surgery that took just 16 minutes, the 18-month-old can hear almost perfectly and enjoys playing with toy drums. [...] The girl, from Oxfordshire, was treated at Addenbrooke's hospital, part of Cambridge university hospitals NHS foundation trust, which is running the Chord trial. More deaf children from the UK, Spain and the US are being recruited to the trial and will all be followed up for five years. [...] Auditory neuropathy can be caused by a fault in the OTOF gene, which makes a protein called otoferlin. This enables cells in the ear to communicate with the hearing nerve. To overcome the fault, the new therapy from biotech firm Regeneron sends a working copy of the gene to the ear. A second child has also recently received the gene therapy treatment at Cambridge university hospitals, with positive results. The overall Chord trial consists of three parts, with three deaf children including Opal receiving a low dose of gene therapy in one ear only. A different set of three children will get a high dose on one side. Then, if that is shown to be safe, more children will receive a dose in both ears at the same time. In total, 18 children worldwide will be recruited to the trial. The gene therapy -- DB-OTO -- is specifically for children with OTOF mutations. A harmless virus is used to carry the working gene into the patient.

Jon Brodkin reports via Ars Technica: T-Mobile, Verizon, and AT&T will pay a combined $10.2 million in a settlement with US states that alleged the carriers falsely advertised wireless plans as "unlimited" and phones as "free." The deal was announced yesterday by New York Attorney General Letitia James. "A multistate investigation found that the companies made false claims in advertisements in New York and across the nation, including misrepresentations about 'unlimited' data plans that were in fact limited and had reduced quality and speed after a certain limit was reached by the user," the announcement said. T-Mobile and Verizon agreed to pay $4.1 million each while AT&T agreed to pay a little over $2 million. The settlement includes AT&T subsidiary Cricket Wireless and Verizon subsidiary TracFone. The settlement involves 49 of the 50 US states (Florida did not participate) and the District of Columbia. The states' investigation found that the three major carriers "made several misleading claims in their advertising, including misrepresenting 'unlimited' data plans that were actually limited, offering 'free' phones that came at a cost, and making false promises about switching to different wireless carrier plans." "AT&T, Verizon, and T-Mobile lied to millions of consumers, making false promises of free phones and 'unlimited' data plans that were simply untrue," James said. "Big companies are not excused from following the law and cannot trick consumers into paying for services they will never receive." The carriers denied any illegal conduct despite agreeing to the settlement. In addition to payments to each state, the carriers agreed to changes in their advertising practices. It's unclear whether consumers will get any refunds out of the settlement, however. These are the following changes the three carriers agreed upon, as highlighted by the NY attorney general's office: - "Unlimited" mobile data plans can only be marketed if there are no limits on the quantity of data allowed during a billing cycle. - Offers to pay for consumers to switch to a different wireless carrier must clearly disclose how much a consumer will be paid, how consumers will be paid, when consumers can expect payment, and any additional requirements consumers have to meet to get paid. - Offers of "free" wireless devices or services must clearly state everything a consumer must do to receive the "free" devices or services. - Offers to lease wireless devices must clearly state that the consumer will be entering into a lease agreement. - All "savings" claims must have a reasonable basis. If a wireless carrier claims that consumers will save using its services compared to another wireless carrier, the claim must be based on similar goods or services or differences must be clearly explained to the consumer. The advertising restrictions are to be in place for five years.
