We believed that laboratories and millions were needed to build a GPU. A maker is setting one up at home

by

For years we have assumed that build a GPU It was a field reserved for companies with advanced factories, engineering teams and million-dollar budgets. It wasn’t an absurd idea: just look at the complexity of any modern graphics card to understand why it seemed out of reach for a person. But what he has done Matthias Balwierzknown as Bitluni, forces us to qualify that certainty. It has not replicated a GeForce nor does it intend to compete with NVIDIA, but it does is building from home a graphics machine with thousands of RISC-V microcontrollers. The first phase brings together 8,192 of those microcontrollers, each linked directly to an RGB LED. This decision makes the montage difficult to fit into the usual categories: the design brings together in the same structure the graphic processing and the surface on which the result must appear. In technical terms, it is designed to act as both a graphics card and a screen, without depending on a separate monitor. Of course, the project remains a partial prototype, still far from the scale and capabilities planned for the complete system. A GPU made pixel by pixel That architecture was not defined from the beginning. The maker began thinking about building some type of screen, but when studying the cost and difficulty of the project he ruled out resorting to components Addressable RGBwhich would have made the whole set too expensive. The alternative was more direct: solder an LED to each microcontroller and turn each chip into a visible graphics unit on its own. The decision contained part of the budget, although it multiplied the design, assembly and programming work necessary to coordinate thousands of elements. The scale becomes clearer when we look at the complete objective. A resolution of 1920×1080 would have required more than two million microcontrollers, shooting the cost and complexity far beyond what Bitluni had set itself. The maker then lowered the ambition to 320×200 pixels, a resolution associated with video games of the DOS era, but which still requires 64,000 chips. The components installed so far represent just a first stage of a machine that would multiply its size almost eightfold if it is completed. To organize such a large amount of hardware, Bitluni divided the system into 16×32 “pixel” boards, conceived as independent modules within the set. These are distributed in a circular arrangement that reminds of Cray-1the historic supercomputer of the seventies, although the reference is mainly visual. Internal coordination is also hierarchical: each group of 32 microcontrollers is under the control of a more powerful CH32V unit, in charge of organizing the operation of that section and serving as an intermediate level within the machine. The choice of the QingKe CH570 explains part of the economic logic of the project. It is a microcontroller with a 32-bit RISC-V CPU, a limited instruction set and a frequency of up to 100 MHz. It also integrates a USB controller, a 2.4 GHz transceiver and support for Bluetooth 5.0 LE. Bitluni was able to buy each unit for about $0.13, but the advantage is diluted when multiplied by the entire planned matrix: only the chips necessary to reach 320×200 pixels would exceed $8,000. The problem grows when projecting the power supply of the complete system. It speaks of an estimate of 2,161 W, equivalent to about 655 amps at 3.3Vfor the final planned configuration. The media points out that each microcontroller consumes around 10 mA, although it does not offer a breakdown that allows us to separate the expense of the chips, LEDs and auxiliary electronics. To support such a load, Bitluni has turned to a source Corsair WS3000 and own converters capable of transforming the 12 V output into the required 3.3 V. A big part of the project is also making the infrastructure that allows everything else to work. Bitluni designed the PCBs, power circuits, interface boards and breadboards, tackling a six-layer board for the first time. The complexity of the design ended up pushing him to the limits of the manufacturing service he used. In parallel, he studied an immersion cooling solution and came to the size of the acrylic container he would have needed, although he left that option on hold for economic and environmental reasons. Programming posed another problem of scale: it was not enough to manufacture the boards, the code also had to be loaded into each microcontroller. To avoid doing it by hand, Bitluni 3D printed a small tool with three contacts and attached it to the carriage. a 3D printer. A Python script sent G-code commands to move it to the exact position of each chip and complete the process in a repeatable manner. The printer thus stopped manufacturing parts to become an automated programming machine. This machine does not compete in performance, efficiency or size with a modern graphics card, nor has it yet reached the scale that Bitluni projected. Its value lies in exposing, through separate components, tasks that a commercial solution concentrates or distributes among specialized chips and circuits: calculation, control, power, coordination and visualization. By rebuilding them with low-cost microcontrollers, the maker has turned an unusual idea into a system that can be designed, tested and expanded in stages. It is not a conventional home GPU, but an engineering experiment taken to unusual limits.

The emir of Qatar’s superyacht needed some repairs. Just giving it a coat of paint already costs 13 million euros

by

The most luxurious yacht in the Persian Gulf has just returned to the water after missing for months. Nobody knew much about where it had been during all that time or what they did to it, even the manufacturer of the Emir of Qatar’s superyacht. he published it on his Instagram profile. It is only known that it left a German shipyard and that, when it reappeared off Gibraltar, it looked like new. As and how I collected Luxury Launchesbehind that “like new” there is a bill that few ordinary owners could assume: more than 35 million dollars. And we’re talking about giving it little more than a lick of paint. Once again, millionaires show us why only they can afford have these superyachts. A tune-up for a 500 million yacht. He Al Lusail belongs to the sheikh Tamim bin Hamad Al Thaniemir of Qatar, and is one of the largest private yachts on the planet. It is 123 meters long and has capacity for 36 guests served by a crew of 56 people, as collected Yacht Bible. The emir ordered it to the manufacturer Lürssen in 2017, so after almost a decade sailing, it was time to give it a coat of paint. That’s why the yacht mysteriously disappeared from the marinas of the Spanish coast by which he used to be seen before summer. now we know that, during the last seven months, the Al Lusail has been at the Lürssen shipyard in Bremen undergoing maintenance, and returned in time for the summer season. What it really costs to take care of an 8,489-ton ship. According to Lürssen in your publicationthe work included technical reviews, hull inspection, propeller and rudder maintenance, and HVAC system upgrades. Nothing very flashy, but essential on a ship that weighs nearly 8,500 tons. The shipyard did not give exact figures, although according to estimates Luxury Launchesthe price of the full service could rise to about $35 million. Of that amount, a good part goes just in paint. Repainting a yacht of this size requires first removing all hardware, steel railings and window seals. According to they explain responsible for specialized shipyards Boat Internationalpreparation (sanding, treating corrosion, leaving the surface perfect) represents 70% of the work. The paint job, itself, is the easy part. 13 million euros in painting. On a medium-sized boat, the job of repainting the hull would cost, at most, a few hundred thousand euros. But he Al Lusail It is not an average ship, it is the height of a six-seven-story building. Its six decks, enormous glass facades and the curvature of its hull complicate the work and that shoots the final price above 15 million dollars (about 13 million euros), just to leave the exterior impeccable. To that figure must be added the rest of the maintenance work, engine and electrical system checks, renewal of fabrics and furniture in the cabins, etc. In summary, the Al Lusailhas complied with the rule that says that the maintenance of a yacht involves an average of 10% of its price of purchase. Taking into account that its price is estimated at around 500 million dollars, the Emir of Qatar even found this revision cheap. An owner for whom this is pocket change. Tamim bin Hamad Al Thani, current emir of Qatar, is a descendant of one of the most influential dynasties of the Arab world and presides over one of the sovereign funds largest in the world that manages assets for about 475,000 million dollars. The emir himself donated one of the Boeing 747s that used as private jetsto serve as Temporary Air Force One in the United States. The truth is that now, with the hull shining and the engines ready, the Al Lusail is ready for another summer in the Mediterranean. And its owner probably won’t even have noticed the damage he left in the box.

Mexico desperately needed Mexicans to care about axolotls. So he put them on the bills

by

The cultural phenomenon around Mexican axolotl It began with an apparently modest gesture: its appearance on a bill, part of a design process in which specialists in Xochimilco advised the Bank of Mexico to faithfully represent this unique species and its chinampero ecosystem. The initial intention was pedagogical and symbolic, but it ended up unleashing an unexpected enthusiasm of unknown dimensions. The creature that conquered a country. As we said, the emergence in 2021 of the axolotl on the Mexican 50 peso bill completely transformed the country’s relationship with a species that, until then, was known only by specialists and inhabitants from Xochimilco. From the first day of circulation, the design captivated millions of people, not only for its aesthetics, but for the soft and enigmatic figure of the amphibian that, unintentionally, embodied a mixture of tenderness, identity and cultural pride. Without millions in circulation. The bill became an immediate phenomenon: collectors, families and young people began to keep it as a small treasure, which explains that, in 2025, more than four years later, the Bank of Mexico (Banxico) announced through a report that 9.8 million Mexicans They keep or collect this bill as if it were a treasure and they have decided to remove it from circulation. In fact, the bank has detailed that 68% of those consulted, who responded that they keep or collect this paper money, have one to five units. According to the calculation, if 9.8 million Mexicans keep a 50 bill, it is estimated that around 490 million pesos of this currency, or its approximate equivalent of more than 26 million dollarsare out of circulation. Hallucinatory. Awards. Its success even led to it being internationally awarded as ticket of the yearconsecrating what was already intuited: the image of the axolotl had connected with a collective sensitivity that went far beyond the economic. And behind that image there was a real animal, an axolotl called Gordaselected after a careful process of documentation and photography, which ended up becoming a national figure without anyone planning it. The daily life of la Gorda. Gorda currently lives in Axolotitlán, the National Axolotl Museumwhere she remains in a deep and well-kept fish tank where she is no longer constantly exposed due to her advanced age. Even so, those who visit it can recognize it by small white spots on its head, a feature that ended up becoming its hallmark. Its fame has generated a parallel ecosystem of objects and souvenirs (from stuffed animals to mugs and clothing) that have reinforced its presence in the country’s daily life. But beyond popular culture, specialists have remembered that admiration also implies responsibility: the axolotl is a extremely fragile speciesdependent on a specific environment, and its sudden notoriety only makes sense if it translates into greater awareness about its conservation. Gorda’s story shows that a single specimen can become a bridge between citizens and nature, but also that collective emotion must be accompanied by decisions that guarantee the survival of the species. An extraordinary creature. The qualities axolotl biologicalfrom its ability to regenerate limbs, tissues and even parts of the brain, to its breathing through gills, skin and mouth, or its condition as a salamander that does not complete metamorphosis, have made it a unique animal in the world. However, this singularity coexists with a critical situation: he Ambystoma mexicanum It is classified as extremely endangered and the destruction of its habitat has been constant for decades. Xochimilco, the only place where this species exists naturally, faces a combination of threats: accelerated urbanization, water pollution and the presence of invasive species that have decimated native ones since the 1980s. And more. Added to this are improvised interventionssuch as the release of axolotls without scientific protocols, which end in almost immediate mortality due to thermal shock, poor water quality or competition between specimens. The specialists they insist in which the conservation of the axolotl is not an act of isolated goodwill, but a technical process that requires strict control of the environment, genetic evaluation, slow acclimatization and comprehensive protection of the channels. The fragility of the animal reflects the fragility of the ecosystem that supports it. Restore Xochimilco. Scientists say that the conservation of the axolotl is inseparable from recovery of Xochimilcoand that evidence has led researchers and chinamperos to undertake shelter projects that recover ancestral agricultural techniques. These restored chinampas act as safe microecosystems where axolotls can remain free of contact with invasive species and with adequate water quality. The objective is not to create artificial reserves, but return to the environment its original balance so that the species can survive without eternally depending on human intervention. Xochimilco is not just a historical heritage nor a tourist postcard, it is a living system that regulates floods, stabilizes temperature, supports traditional agriculture and houses a biodiversity that depends on its continuity. The axolotl is only the visible tip of a problem much broader: if your home disappears, ecological functions on which the entire region depends will also disappear. Takeoff and the World Cup. Since May 2026, the government of Mexico City (with the head of government Clara Brugada at the helm) has taken the image of the axolotl to a much larger scale in view of the 2026 World Cup that is being held: the Light Train has been renamed like “The Axolotl” (with an investment of more than 2.3 billion pesos), bridges, pedestrian crossings, buses and street furniture have been painted purple and decorated with axolotls in what the Mexican press has dubbed “axolotization”, and an official city mascot was even presented for the tournament (“Ajolotín”). The phenomenon has generated so much viral memes as reviews for public spending and for using the animal symbol while the real species continues to decline. The hype. Be that as it may, the social phenomenon of the 50 peso bill demonstrated that an image can change public perception of an entire species. Gorda became a symbol recognized by millions of people, capable of arousing curiosity, affection … Read more

All that was needed was a subsidiary in Malaysia

by

The US Government has suspected for several years that Chinese companies and research centers dedicated to artificial intelligence (IA) acquire Nvidia’s most advanced GPUs through Singapore and Malaysia intermediary companies. In 2022 it decided to ban the sale to China of the most powerful AI GPUs designed by Nvidia, AMD and other American companies in an attempt to stop the use of this technology by the Chinese military. Since then, the US and Chinese Administrations have maintained a constant pulse that not only affects the integrated circuit industry; It permeates everything to the extent that AI chips support a critical technology for both nations. Be that as it may, the biggest obstacle that the US faces in this scenario is parallel import routes. The Commerce Department is trying to make it harder for cutting-edge American chips to reach China, but surprisingly, the Trump Administration hasn’t made it easy. In May 2025 the Government led by Donald Trump decided to freeze the AI ​​Diffusion rulean AI GPU export control regulation that the Biden Administration approved in its final days in office, in January 2025. This regulation established a three-tier system for global access to advanced AI chips. In this way, US allies could obtain them without limitations, but China, Russia or Iran had access completely blocked. Malaysia: the biggest legal loophole in the chip war between the US and China AI chip designers led by Nvidia reacted strongly against the AI Diffusion rule. Their argument maintained that this regulation was essentially bureaucratic and penalized sales to allied or neutral countries. Donald Trump’s government responded. In May 2025 it announced that it would develop its own regulations, and that it would be “bolder and more inclusive”, so it left the AI Diffusion rule not applied. The Trump Administration unintentionally created a legal loophole that has been taken advantage of by many Chinese companies Here comes the unexpected turn of events. By suspending its application, the Trump Administration unintentionally created a legal loophole that has been taken advantage of by many Chinese companies. The AI Diffusion rule required the granting of a license by the US Department of Commerce to be able to sell chips to foreign subsidiaries of Chinese companies. Since this regulation did not prosper, according to SCMPDuring the last year, many Chinese companies have freely purchased Nvidia’s Blackwell and Rubin GPUs, and AMD’s MI350x, from their subsidiaries in Malaysia. Just 48 hours ago the Office of Industry and Security of the US Department of Commerce public a guideline that seeks to close that legal loophole. What it does is simply require compliance with licensing requirements for advanced chips destined for entities based in China, even when those entities are physically located outside the country. However, this new guideline does not require data centers to stop using chips already purchased, so according to Chris McGuirea technology expert and former State Department official, “closes one loophole, but leaves another open.” McGuire does not specify what that second loophole is, but experts point out to the path that remains open through TSMC: Chinese subsidiaries can also access the manufacturing capacity of the Taiwanese semiconductor giant without the new guideline explicitly regulating it.

the technology needed to spy and make military decisions from the sky

by

Artificial Intelligence (AI) carries many benefits, but also many risks. Therefore, eliminating human supervision can be a very bad idea. It is a fairly recurring topic that has been put back on the table after China announced that it is testing the use of AI to advance its satellite-based surveillance systems. Many experts have expressed concern about the possibility of these systems being used for military purposes. Other countries, such as the United States and Israel, have set a worrying precedent, so there is some fear that these technologies could be misused and end up being lethal. The steps of China. China has long stressed the importance of AI always having human supervision. However, the announcement that have collected media such as Interesting Engineering follows a different premise. The Asian country intends for its satellite AI systems to be capable of breaking down complex tasks, coordinating workflows and recovering independently from possible failures. In short, they would use algorithms capable of analyzing information, making decisions and acting without the need for humans. Satellite observation can have many uses, from analyzing animal behavior to aiding weather forecasts. However, this emphasis on AI being able to act on its own is inevitably reminiscent of what we are already seeing in the United States for military purposes. The case of the United States. The US military is suspected of having several AI-based targeting systems, although there is a lot of classified information about them. Broadly speaking, these would use data obtained through optical cameras, infrared, radar, LIDAR and other sensors to locate military targets and subsequently shoot if deemed necessary. Last February, the attack on a school classified as erroneous opened the debate on this issue. In it 175 people diedmostly girls. As it was recognized as a misguided attack, suspicions grew that AI was behind it. As this is classified information, it cannot be known for sure, but it is a more than tangible risk. USA has hired currently to SpaceX to improve the connectivity of the shooters so that they receive the information as soon as possible whether to shoot or not. It is clear that they want to continue advancing in this aspect and it is something that, logically, is of great concern to experts. The case of Israel. It is not exactly the same, but Israel has also left war decisions in the hands of AI, with worrying results. For example, they have a system that uses data from phone calls, social networks, metadata, visual information or contacts, among other sources, to determine who may be targets. According to an investigation by +972 Magazinein the first weeks of the war against Palestine detected 37,000 targets as Hamas members. The army itself recognized that the algorithm has a 90% probability of being right. This gives us clues about how catastrophic it can be. More transparency? China has assured that it will have more transparency than other countries by introducing AI in the management of its satellites. However, this does not minimize the concerns of experts. For now, it seems that the algorithms have managed to avoid obstacles independently in the testing phase. For them to be able to shoot, if they are used for that purpose, there is still a long way to go. But it is viable. Therefore, it is urgent that measures be taken to regulate the use of AI without human supervision as much as possible. There are too many human beings with few scruples, but even those may have some more qualms than machines. An AI cannot show concern, conscience or ethics. He also does not ask before shooting if he is not told to do so. Therefore, if we want it to operate satellites capable of observing and controlling what we do on the planet, it would be advisable for us to ensure that someone with scruples remains in charge. Although in some contexts that is difficult to find. Image | Kevin Stadnyk (Unsplash)/Magnific In Xataka | There are planes dropping food into Gaza from the air.

To move the cutting head of the ‘Monica’ tunnel boring machine, a 152-wheel truck was needed. It’s the key to Australia’s ‘water battery’

by

Transporting a gigantic tunnel boring machine to the work point is no small feat, and Madrid has a few things to say about this. However, in Cooma, a small town in the Australian state of New South Wales, they seem to have gotten the hang of it. And the colossal piece of steel crossed its streets at a snail’s pace on a 152 wheel truck. The cargo was part of Snowy 2.0one of the largest energy storage projects in the world. What is it about?. The piece was the central block of the cutting head of the tunnel boring machine named Monica. According to Snowy Hydro, the public company behind the project, this component weighs more than 137 tons and measures seven meters wide. The head is the part that really matters in a tunnel boring machine, since it is the rotating disc that faces the rock and crushes it as it moves. Media deployment. Monica’s head is too big to transport in one piece, so it had to be divided into five parts. Still, just moving the center block required months of preparation. The entire transport reached 73 meters in length, and was moved at night facing the last stretch along the Snowy Mountains Highway, heading to the Marica site, north of Kiandra, where the machine would be assembled. A colossal engineering project. This move was just one piece of a much larger puzzle. The company indicates that in the previous weeks more than 140 large loads were delivered to Marica from the port of Port Kembla, south of Sydney. The tunnel boring machines do not arrive assembled, as they are transported in sections (head, drive system, shields, support platforms) and are assembled on site. In fact, last October, the transport of Monica’s motor system (a component about 207 tons and eight meters wide) brought more than 1,500 people to Cooma, in what Snowy Hydro called one of the largest loads ever transported by road in New South Wales. What is all this for? Snowy 2.0 is, in essence, a gigantic water battery. The project will connect the Tantangara and Talbingo reservoirs through some 27 kilometers of tunnels and an underground power station. The idea is to generate electricity by turbineing water when demand is high and, in times of surplus solar and wind energy, pump it back uphill for reuse. The company assures that it will have a capacity of 2,200 megawatts and enough stored energy to supply about three million homes for a week. Start-up. Last February, Snowy Hydro announced that Monica had been commissioned and would be responsible for excavating the section of the tunnel that crosses the Long Plain fault zone, a geologically complicated area. Designed by the German firm Herrenknecht, the machine advances at one end of the tunnel while another tunnel boring machine, Florence, does so at the opposite. The idea is that both are underground before being dismantled. For those dates the project exceeded 70% execution. Snowy 2.0 has not been without controversy with news of cost overruns and delays, and completion is now scheduled for December 2028.

A free program was the snitch I needed on my PC to see what was stealing my storage

by

Windows can be fine for many things (although it is understandable that more and more users have your doubts taking into account the state of the operating system), but its waste management is questionable. Mac (and now Linux) are my main computers, but I have a laptop to play and edit video with Windows 11 and it is torture to see that the disk fills up more and more… and I don’t install as much either. You go to the uninstall applications section and you don’t want to remove any because you use them, but what you see doesn’t add up and you start searching through folders seeing, manually (by clicking on ‘Properties’) how much the suspicious folders weigh. After a long while, you find something: a game you uninstalled two years ago keep taking a good bite out of your SSD and you wonder why the files weren’t deleted when you uninstalled it and why you hadn’t seen it until now. And searching I have found a couple of tools to free up space ghost on your PC in a very visual way that is so useful… that it does not surprise me that current Windows does not include it as standard. Your PC’s trash tree The applications are WizTree and TreeSize Freealthough there is also another one called WinDirStat. They both do the same thing: analyze very quickly the space occupied by everything you have in your PC storage. Both show it in various ways and both have something special: the “tree” view. To clean the PC I have used both although the screenshots are from TreeSize, but in fact I recommend WizTree because while TreeSize is an app with trial periods, WizTree is free and you decide if you donate to the creators. There I see that I have large folders like Twitter history or Nintendo Satellaview files. I don’t want to delete them, but I have already missed some GoG games that I haven’t deleted and I am interested in deleting them That said, what makes these tools special and more useful than a list with weights is that they actually show the size that files and folders are taking up on your PC. For example, if you have a PC with a 512 GB SSD and you install ‘Forza Horizon 6‘ and its almost 120 GB, that folder will appear taking up a quarter of the screen. In that case, you can easily identify which folder is eating up the PC storage and you can act accordingly, but what I was most interested in was seeing where did those GB come from? that they were slowly colonizing the SSD without my being aware. After the first pass, which takes no time at all, TreeSize identified and classified all the folders and files on the PC. By default it does not do so in that tree view, but in a more traditional list of folders ordered by weight, but in the options at the top you can choose to show the tree view and indicate how many files it has, the percentage it occupies in your storage or what I prefer: GB. And yes, I saw known evils (the Windows folder takes up a lot), but I also saw what I wanted to see: what was eating up my storage. There were a couple of residual folders of games with several MB and even some silly GB, but the rest of the ‘garbage’ I have to admit was my fault. Almost 16 GB of Steam clips folder on laptop Before delete TwitterI downloaded my file with photos and it turns out that I left it there, taking up a whopping 12 GB. I had completely forgotten about it and it was eating up the space of a couple of good indie games. On the other hand, there was a Steam folder of almost 60 GB on a PC and about 16 GB in another that did not correspond to installed games: they were captures and recordings. How to do screenshots with Steam It is the app itself that manages them in internal folders within its directory (and each video file is divided into several files because they use a peculiar format), I had not realized that, little by little, that folder was filling up. I also had there the files of a prototype game that I downloaded years ago and they were taking up 5 GB and something that bothered me: the PC hibernation file. On the laptop it took up about 6 GB, but on the desktop it was almost 10. The laptop was good, but I almost never left it idle on the desktop, so I deleted it and deactivated hibernation (because if you delete the file and don’t deactivate hibernation, it creates it again). The first impression is that of a somewhat dense app, but as soon as you have been using it for a while you begin to know how to “read” the interface So… well, the space freed up on the two PCs is not bad. a way that Windows natively does not offer me. And I can’t complain because in the end a lot of the garbage that was on my PC was my fault, but looking for information about these applications I came across this article by MeinMMO where they had uninstalled a game years ago, but it was still taking up 62GB on the SSD. The game is ‘Wild Hearts‘ and they say that they played it the way you can play Electronic Arts games (unfortunately): through the EA application. He uninstalled it in 2023, but although it no longer appeared as installed in Windows space management, it seems that the entire game was still on his hard drive. He details that it was not just the profile configuration or data like that (which would still be stupid), but the entire game. It is not the only game that left residue: 20 GB of modsArk: Survival Evolved‘ … Read more

China has just discovered the largest deposit of rare earths in the world. And he did it just when he needed it most.

by

China has a privileged position in terms of possession of rare earthbut it has just surprised the world with a new discovery: the Ministry of Natural Resources has confirmed that the Maoniuping deposit, in Sichuan province, is now the largest deposit of light rare earths on the planet. The news comes at a key moment, since it is these minerals that are the protagonists one of the hottest fronts between Beijing and Washington in their tariff war. What exactly has been found. New exploration in the Maoniuping mining area in Mianning county has confirmed the existence of 9.67 million tons of rare earth oxideswhich represents an increase of more than 300% compared to the reserves that were known until now, as announced by the Chinese Ministry of Natural Resources. With this data, the deposit surpasses that of Bayan Obo, in Inner Mongolia, which until now held the title of the largest light rare earth mine in the world with 44 million tons of proven industrial reserves. In addition to rare earth oxides, surveys have identified 27.1 million tons of fluorspar and 37.2 million tons of barite, both classified as deposits of exceptional scale. Why does it matter? Rare earth elements are the 17 elements that make electric car engines, fiber optic amplifiers, advanced weapons systems and smartphones possible, among many other technological elements that we use in our daily lives. Without them, much of the technology and defense industry simply does not work. China already produces more than 80% of the world supply annual of these materials, according to the state agency Xinhua. And this discovery further reinforces China’s position until now. The discovery within the discovery. According to Wang Denghong, director of the Institute of Mineral Resources of the Chinese Academy of Geological Sciences, what is truly striking about the discovery is not only the rare earths but fluorite and barite. Fluorite is an essential ingredient in the manufacturing of semiconductors and lithium-ion batteries. Barite, for its part, is essential in oil and gas extraction: it is used to stabilize wells and prevent blowouts. Without this element, hydrocarbon exploration, including fracking, would be paralyzed. Restrictions. Since April last year, China introduced export restrictions on seven rare earths and permanent magnets, precisely in response to the tariffs imposed by Donald Trump about Chinese products. China controls the gateway to rare earths, and basically any company that wants to take these materials out of the country needs express government authorization. Exports to Europe have picked up since the new licensing regime was implemented. Those going to the United States remain stagnant, according to collect Interesting Engineering. What’s coming now. With this discovery, Beijing consolidates its ability to use critical minerals as diplomatic and commercial leverage. The West has been trying for years diversify your supply chains of rare earths with projects in Australia, Canada or northern Europe, but none yet approach the scale of the Asian country.

It turns out that to innovate in mobile phones, only one thing was needed: (very) useful little things.

by

Neither the latest Qualcomm processor, nor “agent” AI, nor a camera with 200 megapixels. What surprised us most this week with the launch of the Galaxy S26 Ultra It was his anti-gossip screen. A friendly reminder that, perhaps, innovation in technology does not involve the most technical characteristic, but rather the most useful one. A touch of attention. We have been criticizing for years (and rightly so) that mobile phones do not innovate. For some time now, attending the presentation of a new model is usually summarized in: Same mobile Best camera (sometimes not even that) More power AI functions that, with a high probability, we will never use The umpteenth improvement in hardware that has been nearing its peak for years This is why, as soon as we see one of those novelties of the “oh, I want that in my daily life“, we return to that smile from when mobile phones were devices designed to make our lives easier, and not so much to sell hardware deployments at the highest possible price. The anti-peeping screen. Yes, we already know that there are €1 screen protectors that perform a similar function, but the point is that this screen includes it from the factory, and with brutal technology. It is capable of regulating the emission of the pixels so that we are only able to see the panel from the front. This opens the door to having a native security layer on our screen and, by the way, being able to put a quality screen protector on it (protection ones are usually not). The matte screen. A couple of years ago, Samsung surprised the world with the matte screen of the Samsung Galaxy S24an anti-reflective layer that represented a before and after when viewing content. Apple tried something similar in its last generation, but couldn’t come close. Once again, a silent innovation that did not impress on the technical sheet, but in terms of utility it was outstanding. Apple’s square sensor. People take selfies, lots of selfies. And turning the phone to do them is not a drama, but if you can save it, all the better. It is just what Apple invented with its iPhone 17 and the square sensor: one that allows the mobile to record and take photos both vertically and horizontally in the same position. NXTpaper screens. Although the superiority of the physical book over the electronic reader is a debate that I do not want to open (and that I do not intend to lose), TCL has been doing something for some time that its competition does not dare to imitate: dual panelswhich can be used as an electronic reader and as a traditional panel. How does it work? These phones and tablets are modified LCD panels with a different matrix than the rest. The backlighting system, the anti-reflective layer and the microtexture of the surface itself are adjusted to emulate an electronic ink panel, and thus be much less aggressive to the eye when we are reading. 10,000mAh batteries. Quietly, smartphone batteries are undergoing their biggest revolution. The main change: betting on silicon to give us much more generous capacities. Because yes, innovating is making the phone last three days, and not one as we have been accustomed to for years.

what is needed are cheaper chips

Let’s face it, I’ve been using high-end phones for more than a decade, but I tend to test mid-range phones quite frequently and it’s been clear to me for a long time that you can buy a smartphone for 300 euros and have decent performance for standard use. Obviously, not for a gamer or a demanding user, but for the average user. Hence the mobile phones that I most recommend They cost between 300 and 500 euros. This upward range has two explanations: the first, that in addition to performance, it is common for “a good camera” to appear on many people’s wish lists. And here, the Google Pixel A is the king. The second is a market where the price increase is inevitable because everything goes up, but especially components like memory or storagewhich can lead to the tragic news of recover 4GB of RAM. Qualcomm is the manufacturer that equips most of the premium Android phones on the market and according to rumorsits next flagship will arrive twice: a Pro version for the ultra-premium range and another for the pure high-end. The difference between the two would be the type of RAM supported and the GPU configuration, similar to what Apple does with its iPhones. Surely their benchmarks are printable, but More than its advantages, what worries me is the price. The cost of current Snapdragon 8 Elite Gen 5 They are around 280 dollars and for the following ones everything indicates that They will overcome the barrier of 300 dollars. This means that for many manufacturers, just purchasing the processor will account for a third of the RRP of their devices. Google shows that another path is possible Meanwhile, Google is going its own way within the ecosystem: Your Tensors are never at the top of performance and not only do they not seem to care, but they continue to offer seven years of updates even in their A versions. For more ridicule, their new Google Pixel 10A even repeats processor. And nothing happens: any mid-range from the last three years will allow you to successfully use messaging, social networks or browse the internet. It is true that there are specific use scenarios where continuing to add more and better hardware can be differential, such as ray tracing, moving games with a certain cadence, or AI. But on the one hand it is something niche and on the other, current models can still give a fight. And I’m not just talking about the high-end. Google Product Manager, Toni Urban, makes quite a statement of intent: We had to make difficult engineering decisions to maintain that price of 549 euros, which we have maintained for four generations. The chipset is part of that consideration. We knew we could still deliver the best of Google’s AI and the best camera experience with the chip we had; We didn’t feel like we were sacrificing quality, and we still continued to incorporate important improvements. If a medium range of a couple of years can continue to carry out normal and current tasks in a solvent manner, with a veteran high-end, even better. It is rare to find someone who renews a high-end one for another citing performance reasons. The bottleneck is another: it could be the camera, thermal management or the battery and its performance, because performance is a problem solved years ago on mobile phones. Google’s decision not only seems right from a price point of view, but also from a balance point of view: performance tests take a backseat when factors such as temperature or battery life act as limitations. Not obsessing over performance allows manufacturers to differentiate themselves in other areas or simply maintain their prices. And that is no small thing.
