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.

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

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.

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.

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.

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.

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.

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...

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 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."

Gemini is (finally) rolling out on Android Auto, replacing Google Assistant while keeping "Hey Google," adding Gemini Live ("let's talk live"), message auto-translation, and new privacy toggles. "One feature lost between Assistant and Gemini, though, is the ability to use nicknames for contacts," notes 9to5Google. From the report: Over the past 24 hours, Google has quietly started the rollout of Gemini for Android Auto, seemingly starting with beta users. The change is server-side, with multiple users reporting that Gemini has gone live in the car. One user mentions that they noticed this on Android Auto 15.6, and we're seeing the same on our Pixel 10 Pro XL connected to different car displays, and also on a Galaxy Z Fold 7 running Android Auto 15.7. It's unclear if this particular version is what delivers support, but that seems unlikely seeing as this very started rolling out last week. Android Auto 15.6 and 15.7 are currently only available in beta, so it's also unclear at this time if the rollout is tied to the Android Auto beta or simply showing up on that version as a coincidence.

An anonymous reader quotes a report from the Associated Press: Denmark's government on Friday announced an agreement to ban access to social media for anyone under 15, ratcheting up pressure on Big Tech platforms as concerns grow that kids are getting too swept up in a digitized world of harmful content and commercial interests. The move would give some parents -- after a specific assessment -- the right to let their children access social media from age 13. It wasn't immediately clear how such a ban would be enforced: Many tech platforms already restrict pre-teens from signing up. Officials and experts say such restrictions don't always work. Such a measure would be among the most sweeping steps yet by a European Union government to limit use of social media among teens and younger children, which has drawn concerns in many parts of an increasingly online world. "We've given the tech giants so many chances to stand up and to do something about what is happening on their platforms. They haven't done it," said Caroline Stage, Denmark's minister for digital affairs. "So now we will take over the steering wheel and make sure that our children's futures are safe." "I can assure you that Denmark will hurry, but we won't do it too quickly because we need to make sure that the regulation is right and that there is no loopholes for the tech giants to go through," Stage said.

An anonymous reader shares a report: Nintendo has always been a company willing to try just about anything. Cardboard cutout toys that mesh with games? Done. A console called the Wii with a remote-shaped controller? Massive success. Legendary game designer and Nintendo executive Shigeru Miyamoto offered more insight into how the company operates in a recent financial briefing. "Nintendo has always worked with the idea that there are no limits to our efforts," he said. "For example, when we tried our hand at movies with The Super Mario Bros. Movie, its success was compared to the box office revenues of other movies. However, even if the movie topped the rankings, we would think there was more room for growth." Nintendo has been expanding its efforts in Hollywood after The Super Mario Bros. Movie became one of the best-selling films of 2023. The Legend of Zelda movie is now in production, and the Super Mario Galaxy movie is expected sometime in 2026. Miyamoto believes that some Nintendo IPs could see sales numbers "potentially reach beyond the boundaries of entertainment." "My latest theme is that there is no ceiling in the world of entertainment," he said. "In that sense, there are still many markets around the world that can be expanded through Nintendo Switch [...] One thing that is interesting about Nintendo is that it's okay to try anything."

NextGov: The IRS has notified states that offered the free, government tax filing service known as Direct File in 2025 that the program won't be available next filing season. In an email sent from the IRS to 25 states, the tax agency thanked them for collaborating and noted that "no launch date has been set for the future." "IRS Direct File will not be available in Filing Season 2026," says the Monday email, obtained by Nextgov/FCW and confirmed by multiple sources. It follows reports that the program was ending and Trump's former tax chief, Billy Long, remarking over the summer that the service was "gone." The program, which debuted in 2024, was a big shift from the decades-long IRS policy of not competing with the tax prep industry in offering its own free, online tax filing service for Americans. Many Republicans had opposed Direct File, and tax prep companies also lobbied against it.

Web-based video games are experiencing an unexpected revival as the broader $189 billion industry stagnates. Sales for browser-based titles like GeoGuessr and chess were expected to triple from 2021 to 2028, reaching $3.09 billion, according to Google and Kantar. Playgama hosted more than 15,000 new web games in the first half of 2025, exceeding the combined total from 2021 through 2023. Websites provide fast and easy access without console boot-ups or app downloads. Game creators sidestep the 30% revenue cuts imposed by Steam and Apple. Poki has doubled its employee count to 70 since 2020 and now serves 100 million monthly active users. A top-ten developer on the platform earns about $1 million in yearly revenue, up from $50,000 in 2020. Consoles cost more than $450, and smartphone gamers are downloading fewer apps. Electronic Arts founder Trip Hawkins predicted web games will be "one of the next waves."

An anonymous reader shares a report: On the new MacOS 26 (Tahoe), Apple has mandated that all application icons fit into their prescribed squircle. No longer can icons have distinct shapes, nor even any fun frame-breaking accessories. Should an icon be so foolish as to try to have a bit of personality, it will find itself stuffed into a dingy gray icon jail. [...] While Apple had previously urged developers to use squircle icons on our apps, they've now taken things much further to ensure compliance. It's a shame. Apple updated their own app icons on Tahoe, for both the squircle shape as well as the new "Liquid Glass" interface. Mostly, these icons seem dumbed-down, with a loss of detail.
