Samsung va présenter sa première LPDDR6 au CES 2026. Elle ne fait pas rêver, mais ce n'est que le début !

En juillet 2018, Samsung annonçait sa première LPDDR5. Elle était gravée en "10nm class" pour reprendre les mots du communiqué officiel, et pouvait monter à 6400 Gbps de débits. Elle faisait alors suite à la LPDDR4 qui avait été annoncée par Samsung fin 2014. En janvier 2026, lors du CES de Las Vega...

Unesco Adopts Global Standards On 'Wild West' Field of Neurotechnology

Par :BeauHD
8 novembre 2025 à 10:00
Unesco has adopted the first global ethical standards for neurotechnology, defining "neural data" and outlining more than 100 recommendations aimed at safeguarding mental privacy. "There is no control," said Unesco's chief of bioethics, Dafna Feinholz. "We have to inform the people about the risks, the potential benefits, the alternatives, so that people have the possibility to say 'I accept, or I don't accept.'" The Guardian reports: She said the new standards were driven by two recent developments in neurotechnology: artificial intelligence (AI), which offers vast possibilities in decoding brain data, and the proliferation of consumer-grade neurotech devices such as earbuds that claim to read brain activity and glasses that track eye movements. The standards define a new category of data, "neural data," and suggest guidelines governing its protection. A list of more than 100 recommendations ranges from rights-based concerns to addressing scenarios that are -- at least for now -- science fiction, such as companies using neurotechnology to subliminally market to people during their dreams. "Neurotechnology has the potential to define the next frontier of human progress, but it is not without risks," said Unesco's director general, Audrey Azoulay. The new standards would "enshrine the inviolability of the human mind," she said.

SARCASM : un robot railleur qui résout les Rubik’s Cube

8 novembre 2025 à 08:01

SARCASM est un acronyme savamment trouvé par Arvind Singh, un vidéaste qui n’a que très peu d’abonné sur sa chaîne Youtube. Les lettres signifient Slightly Annoying Rubik’s Cube Automatic Solving Machine. Ce qui peut se traduire par Machine de résolution de Rubik’s Cube légèrement pénible. 

Dans une longue documentation très complète, l’auteur de ce projet SARCASM détaille toute l’ambition de son projet. Et si la machine a l’air parfaitement inutile, l’ampleur de son développement n’en demeure pas moins exceptionnel. Ce n’est pas la première fois que l’on utilise un robot pour résoudre le cube, divers autres projets ont tenté la même aventure.

La Teensy 4.1

Ce qu’il y a d’intéressant ici, c’est que tout a été fait par une seule personne, avec un matériel relativement simple et surtout grâce à une carte Teensy 4.1. Une carte de développement proposant un microcontrôleur que l’on a retrouvé dans beaucoup de projets par le passé mais loin des machines habituellement capables de réaliser cette opération. Le cœur de cette carte, c’est un petit circuit ARM Cortex-M7 à 600 MHz épaulé par 1 Mo de mémoire vive. Une fraction de ce que les équipes de labos qui veulent parvenir au même résultat emploie en général. L’autre élément vraiment impressionnant, ce n’est pas tant la capacité de calcul de cette solution. C’est le bras de fer logiciel qu’il a fallu établir pour lui permettre de la résoudre de manière indépendante avec les seules ressources embarquées. 

La vision du Cube est pilotée de manière autonome de manière à identifier chaque face et chaque carré de couleur. Ensuite les mouvements sont calculés et le positionnement comme la rotation sont effectués par le robot de manière totalement autonome. L’appareil fonctionne sur batterie et n’a pas besoin d’une connexion ou autre pour trouver la solution.

Le SARCASM porte son nom parce qu’en même temps qu’il trouve la solution du Cube, il se permet de faire quelques remarques désobligeantes au travers du petit affichage de 2.4″ en façade. Pour améliorer son aspect désagréable, une voix de synthèse est générée en temps pour commenter l’action. A la fin de l’opération, le petit écran présente un « ralenti » de l’opération de résolution, en 3D, en se mettant en scène lui-même.  Chose remarquable, énormément des librairies utilisées ici sont des travaux de développement et d’adaptation de l’auteur.

Le SARCASM à la portée de tous

Les cartes du SARCASM

Tout est documenté sur la page Github du projet : la partie logicielle, les éléments matériels, les différents éléments nécessaires pour la réalisation des cartes embarquées. On retrouve également tous les fichiers nécessaires pour imprimer son propre petit robot. L’ensemble du code est par ailleurs proposé… Une vraie mine d’or pour comprendre comment tout cela fonctionne. Avec pas mal de persévérance, vous pouvez fabriquer le même robot vous-même avec toutes les infos nécessaores pour y parvenir.

De la reconnaissance et la résolution du Cube, de l’estimation du nombre de mouvements à effectuer et jusqu’à la synthèse vocale et les contrôles des différents moteurs pas à pas de manipulation. Tout est documenté. Un long fil avec plein de détails et de commentaires est également proposé sur le forum de PJRC qui fabrique la solution Teensy 4.1. 

À l’heure où j’écris ces lignes, Arvind n’a qu’une petite centaine d’abonnés à sa chaine Youtube. Sa vidéo de présentation n’a que 2000 vues un mois après sa publication. Si ce type de projet vous intéresse et vous impressionne, n’hésitez donc pas à l’encourager en vous abonnant. Il s’agit ici d’un travail vraiment impressionnant, riche et partagé. Si la suite de ces productions est au niveau, cela vaut franchement la peine de le suivre.

Merci à Clément pour le lien.

Lego Unveils First-Ever Star Trek Set

Par :BeauHD
8 novembre 2025 à 07:00
New submitter semper_statisticum shares a report from the Independent: Lego is releasing its first-ever Star Trek-inspired model -- with an incredible recreation of the signature ship from the '80s TV series. Made from 3,600 pieces, the [first-ever] Star Trek inspired Lego set is of the U.S.S. Enterprise NCC-1701-D, the spaceship that serves as the main setting of Star Trek: The Next Generation series, which ran for seven seasons, as well as the 1994 film, Star Trek Generations. "[It] allows builders to craft a detailed replica of the iconic starship, complete with a detachable command saucer, secondary hull, and warp nacelles with distinctive red and blue detailing," according to a press release from Lego. "The model also features an opening shuttlebay and two mini shuttlepods, perfect for recreating classic scenes." The set comes with nine mini-figures of Star Trek: The Next Generation characters, including Captain Jean-Luc Picard, Commander William Riker, Lieutenant Worf, Lieutenant Commander Data, Dr. Beverly Crusher, Lieutenant Commander Geordi La Forge, Counsellor Deanna Troi, bartender Guinan, and Wesley Crusher. The set will be sold on Lego's website and in stores for $399.99, with orders shipping on November 28th.

The First New Subsea Habitat In 40 Years Is About To Launch

Par :BeauHD
8 novembre 2025 à 03:30
An anonymous reader quotes a report from MIT Technology Review: Vanguard feels and smells like a new RV. It has long, gray banquettes that convert into bunks, a microwave cleverly hidden under a counter, a functional steel sink with a French press and crockery above. A weird little toilet hides behind a curtain. But some clues hint that you can't just fire up Vanguard's engine and roll off the lot. The least subtle is its door, a massive disc of steel complete with a wheel that spins to lock. Once it is sealed and moved to its permanent home beneath the waves of the Florida Keys National Marine Sanctuary early next year, Vanguard will be the world's first new subsea habitat in nearly four decades. Teams of four scientists will live and work on the seabed for a week at a time, entering and leaving the habitat as scuba divers. Their missions could include reef restoration, species surveys, underwater archaeology, or even astronaut training. One of Vanguard's modules, unappetizingly named the "wet porch," has a permanent opening in the floor (a.k.a. a "moon pool") that doesn't flood because Vanguard's air pressure is matched to the water around it.It is this pressurization that makes the habitat so useful. Scuba divers working at its maximum operational depth of 50 meters would typically need to make a lengthy stop on their way back to the surface to avoid decompression sickness. This painful and potentially fatal condition, better known as the bends, develops if divers surface too quickly. A traditional 50-meter dive gives scuba divers only a handful of minutes on the seafloor, and they can make only a couple of such dives a day. With Vanguard's atmosphere at the same pressure as the water, its aquanauts need to decompress only once, at the end of their stay. They can potentially dive for many hours every day. That could unlock all kinds of new science and exploration.

'Vibe Coding' Named Word of the Year By Collins Dictionary

Par :BeauHD
8 novembre 2025 à 02:20
Collins Dictionary has named "vibe coding" its 2025 word of the year -- a term coined by Andrej Karpathy for when a user makes an app or website by describing it to AI rather than writing programming code manually. The term, which is confusingly made up of two words, was "one of 10 words on a shortlist to reflect the mood, language and preoccupations of 2025," reports the BBC. From the report: By giving an AI tool a simple description such as "make me a program that schedules my weekly meals", people can use "vibe coding" to make basic apps without any previous programming knowledge. More complicated tools still require skill, but the practice has opened up creating digital platforms to non-coders. As many have discovered, it isn't perfect - with no guarantee the code will actually work or be free of bugs. Alex Beecroft, the Managing Director of Collins, said the term "perfectly captures how language is evolving alongside technology." Other words that made the list include "clanker," "aura farming," "broligarchy," "biohacking," and "coolcation." You can view the full list here.

James D. Watson, Co-Discoverer of the Structure of DNA, Is Dead At 97

ole_timer shares a report from the New York Times: James D. Watson, who entered the pantheon of science at age 25 when he joined in the discovery of the structure of DNA, one of the most momentous breakthroughs in the history of science, died on Thursday in East Northport, N.Y., on Long Island. He was 97. His death, in a hospice, was confirmed on Friday by his son Duncan, who said Dr. Watson was transferred to the hospice from a hospital this week after being treated there for an infection. Dr. Watson's role in decoding DNA, the genetic blueprint for life, would have been enough to establish him as one of the most important scientists of the 20th century. But he cemented that fame by leading the ambitious Human Genome Project and writing perhaps the most celebrated memoir in science.

'Nintendo Has Too Many Apps'

Par :BeauHD
8 novembre 2025 à 01:00
The Verge's Ash Parrish writes: Nintendo has released a new store app on Android and iOS giving users the ability to purchase hardware, accessories, and games for the Switch and Switch 2. When I open my phone and scroll down to the N's, I get a neat, full row dedicated entirely to Nintendo. That's four apps: the Switch app, the music app, the Nintendo Today news app, and now the store. (The tally increases to five if you're a parent using the Switch Parental Controls app.) And it is entirely too much. Nintendo has always been the one company of the big three publishers that does its own thing, and that's worked both for and against it. The company hasn't chased development trends with the same zeal as Microsoft and Sony. That insulates Nintendo when those trends don't pan out, like exorbitant spending on live-service games that fail. But also hurts it when it comes to performance and user experience. Console-native voice chat, for example, has been a standard on other platforms for a long time, but was only offered on a Nintendo console with the Switch 2 this year. With the deployment of these apps, Nintendo is both trying to innovate and playing catch-up with results that feel confusing and overwhelming. Do we really need four distinct apps? That's not to say these apps shouldn't exist; they serve valuable and necessary purposes. But when I look at all the programs I have to manage in my Nintendo life, it just feels like it's too much...

You Can't Leave Unless You Buy Something

An anonymous reader quotes a report from SFGATE: At the Safeway on San Francisco's King Street, you now can't leave the store unless you buy something. The Mission Bay grocery store recently installed new anti-theft measures at the entrance and exit. New gates at the entrance automatically swing open when customers walk in, but they're set to trigger an alarm if someone attempts to back out. And if you walk into Safeway and change your mind about grocery shopping, you might find yourself trapped: Another gate that only opens if you scan your receipt blocks the store's sole exit. During my Monday visit, I purchased a kombucha and went through the check-out line without incident. (No high-tech gates block the exit if you go through the line like normal.) But for journalism's sake, I then headed back into the store to try going out the new gate. While I watched some customers struggle with the new technology, my receipt scanned immediately. The glass doors slid open, and I was free. But if, like this person on the San Francisco subreddit recounted, I hadn't bought anything, my only means of exit would have been to beg the security guard to let me out.

Texas Sues Roblox For Allegedly Failing To Protect Children On Its Platform

Par :BeauHD
7 novembre 2025 à 23:40
Texas is suing Roblox, alleging the company misled parents about safety, ignored online-protection laws, and allowed an environment where predators could target children. Texas AG Ken Paxton said the online game platform is "putting pixel pedophiles and profits over the safety of Texas children," alleging that it is "flagrantly ignoring state and federal online safety laws while deceiving parents about the dangers of its platform." The Verge reports: The lawsuit's examples focus on instances of children who have been abused by predators they met via Roblox, and the activities of groups like 764 which have used online platforms to identify and blackmail victims into sexually explicit acts or self harm. According to the suit, Roblox's parental controls push only began after a number of lawsuits, and a report released last fall by the short seller Hindenburg that said its "in-game research revealed an X-rated pedophile hellscape, exposing children to grooming, pornography, violent content and extremely abusive speech." Eric Porterfield, Senior Director of Policy Communications at Roblox, said in a statement: "We are disappointed that, rather than working collaboratively with Roblox on this industry-wide challenge and seeking real solutions, the AG has chosen to file a lawsuit based on misrepresentations and sensationalized claims." He added, "We have introduced over 145 safety measures on the platform this year alone."
