The most powerful supercomputer in the world is in China. The other part of the story is even more interesting

by

The biannual TOP500 list with the most powerful supercomputers on the planet has given a striking surprise in its June 2026 edition. The Chinese LineShine system, installed at the Shenzhen National Supercomputing Center, has debuted directly at number one. It thus displaces the American supercomputer El Capitan, which had dominated the ranking for years. China has not managed to lead this classification since 2017, thus breaking a decade of North American hegemony. Unprecedented raw power. The performance tests used to configure this list leave no doubt: LimeShine has achieved 2,198 exaflops of performance in the benchmark HPLcompared to 1,809 exaflops for its American rival. The Chinese machine is therefore 20% more powerful than the flagship of the Lawrence Livermore National Laboratory in California. It is a whole new milestone in global supercomputing. Surprise: zero GPUs. The performance is extraordinary, but even more so is the way this supercomputer has been created. Most modern supercomputers rely heavily on GPUs, specialized graphics chips from Nvidia or AMD, for massive data processing. However, LineShine uses CPUs instead of focusing everything on GPUs, something that differentiates this supercomputer from its rivals and makes the feat even more striking. Heart ARM. The fundamental pillar of LineShine It is the LX2 CPU. The data they point because it has been designed by Huawei, and in each of those CPUs we have two dies HBM computing and memory. Each die It has 152 ARMv9 cores that have EVS and EMS supportwhich allows the system to process vectors and matrices in an exceptional way even without GPUs. In total LineShine has 304 of these processors with a total of 13,789,440 cores. Avoiding vetoes. One of the reasons that have undoubtedly contributed to this design decision is the US trade war with China. Tariffs and export bans on hardware and software have made things very complicated, especially when it comes to getting Nvidia GPUs for AI processing. Despite all this, China has once again demonstrated an astonishing ability to advance technologically. Another curiosity: the system has been built without public funds from the Chinese government. Source: TOP500.org AI clusters don’t compete here (but they would “win”). This prestigious list had always offered us that vision of the most powerful computing systems in the world, but today the panorama has changed. It has done so because the AI ​​clusters created by big technology are probably more powerful than any of these systems. As explains Jimmy Goodrich of the University of California, “if hyperscalers competed with their systems, ‘fastest’ in the world wouldn’t even be in the top five.” That phrase, yes, has crumbs. But it’s comparing pears with apples. However, the supercomputers on the TOP500 list and the AI ​​clusters that hyperscalers are building to meet global demand are very different. The root problem is in floating point precision. Classic supercomputers like El Capitan are designed for high-fidelity scientific simulations, where the slightest rounding error can be fatal. That is why they operate under the FP64 standard with which tens of decimals are calculated: it is a slow and expensive process in energy, but extraordinarily precise. AI rounds with joy. In contrast, AI models are very resistant to numerical “noise.” They don’t need perfect precision to recognize patterns or generate text. That allows AI chips to use reduced precision formats like FP16, FP8, or even FP4. By processing much shorter numbers, they multiply their speed and efficiency significantly. So when an AI cluster achieves tens of exaflops, it does so rounding up quite happily. These machines are exceptional for AI tasks, but they do not threaten the future of traditional supercomputers. Europe (and Italy) and supercomputing. If we look in detail at the list, we see great news for European supercomputing. The HPC7 system created by Eni has entered directly at number 6 on the list, while Jupiter Booster (Germany) is at number 5. Europe has four systems in the top 10 of the TOP500 list (two of them, from Italy), and eight in the top 20. Spain is still present on the list thanks to MareNostrum 5which yes, drops from 14th to 16th place. In Xataka | The EU wants to close the gap in the race for AI with 750 million euros.

Today the new film ‘The Lord of the Rings’ arrives on Netflix by surprise, whose genesis is as interesting as its plot

by

The first Middle Earth anime, ‘The Lord of the Rings: War of the Rohirrim‘, lands on Netflix almost a year and a half after its discreet passage through theaters. The film that Warner swept under the rug a few weeks after its theatrical release is back on streaming, and its commercial journey is as bumpy as the fiction it narrates, set in Tolkien’s immortal creation. The story takes place 183 years before the events narrated in ‘The Fellowship of the Ring’. We will experience the fall of Helm Hammerhand, king of Rohan, against Wulf, a Dunlending lord who seeks to avenge the death of his father. The siege ends at the Tabernacle fortress, the bastion that generations later will be known as Helm’s Deep. In this way, an episode of the story of ‘The Lord of the Rings’ that Tolkien barely left outlined in the appendices is narrated in detail. Behind the camera was Kenji Kamiyama, a Japanese animator who had previously taken the reins of other legendary franchises, as he did in ‘Ghost in the Shell: Stand Alone Complex’ and ‘Blade Runner: Black Lotus’. However, the bet did not work at the box office: the film became the worst premiere of the entire franchise, grossing barely about 4.6 million dollars. Its worldwide collection was around 20 million against a budget close to 30. But… what is the reason for the release, somewhat secretly, of this film? Easy: retain rights. The making of ‘The War of the Rohirrim’ was accelerated so that New Line Cinema would keep the film rights to Tolkien’s work active while prepared new projects. The next step in that plan is ‘The Hunt for Gollum’, now with real actors, Andy Serkis directing and returning to play Gollum, produced by Peter Jackson and scheduled for release in 2027. The machinery continues to move forward, but in the meantime we have this wonderful animated appetizer.

Today you have one of the most interesting and ignored movies of the year on Prime Video

by

Nine Oscar nominations, more than $179 million at the global box office, and one of the most extravagant marketing campaigns Hollywood has given in years (an orange blimp flying over entire cities, Timothée Chalamet perched on the Las Vegas sphere). Still,’Marty Supreme‘She left the last Oscars, where she started as one of the favorites, empty-handed. And (also) still, it is in Prime Videostanding out as one of the most interesting films of the moment. There are films that reach streaming with that aura of a second chance, of being able to achieve on platforms what was not achieved with its premiere (despite the notorious box office for a production of these characteristics, the greatest success in the United States in the history of its production company, the venerated A24). It was nominated for nine Oscars, including Best Picture and Best Actor for Timothée Chalamet, and went home with nothing, following the path of other illustrious recent nods such as ‘The Banshee of Inisherin’ or ‘The Moon Killers’. ‘Marty Supreme’ is directed by Josh Safdie and written with Ronald Bronstein, a creative duo who already collaborated on titles such as ‘Diamonds in the Rough’ and ‘Good Time’. The film moves away from the traditional biopic to become an action-adventure comedy in the spirit of ‘Catch Me If You Can’ or ‘The Wolf of Wall Street’. The central character, Marty Mauser, is a fictionalized version of the real player Marty Reisman, a young man who discovers his passion for table tennis in the city’s clandestine clubsand whose very personal style of play leads him to become a famous champion who accumulates 22 major titles and represents the United States in world competitions. But the important thing here is not the zero Oscars, but the values ​​of the film: it is a delight how Safdie manipulates genres to mix them, how he builds the rhythm of his sequences, and above all, Chalamet’s performance is impressive in what may be the best work of his career. So it’s not about confirming whether the Oscars were right or wrong, but rather about recovering a film that deserves all the attention we can give it.

A young man has solved a mathematical problem that lasted 60 years in 80 minutes with ChatGPT. That’s the least interesting thing about the story.

by

He is 23 years old, his name is Liam Price and he has no advanced mathematical training. Even so, a few days ago he opened the Erdös problem websitepicked one at random and pasted it into ChatGPT. I didn’t know the history of the problem or who had tried it before. What he received back seemed like a good solution, and after consulting with a friend who was studying mathematics, the two realized they might be on to something special. A few hours later Terence Tao, one of the most renowned mathematicians in the world, confirmed that problem #1196 of Erdös, a conjecture about primitive sets of integers that had not been solved since 1966, had a solution. I had found her GPT-5.4 Pro in just 80 minutes. Not like that. This problem analyzed a question about the behavior of a particular mathematical sum on primitive sets, that is, sets of integers where none divides the other, when those numbers become very large. Jared Lichtman, a Stanford mathematician, had spent years on the problem and had made partial progress, but he and those who had tried before were starting from the same starting point that seemed like the right path. A novel idea. GPT-5.4 used another starting point. He stayed in the airmetic terrain and used a special function called von Mangoldt functiona classic tool of number theory known for its connections to prime numbers and Riemann zeta function. No one had thought about that approach to the problem, and as Lichtman explained when talking about the OpenAI model solution, “The LLM took a completely different route.” The achievement is real, but with nuances. Litchman praised the proposed solution by GPT-5.4, but there is one detail that has been omitted in many comments on this event: the raw output of ChatGPT was, in the words of this mathematician, “pretty poor.” This solution made it necessary for several experts to interpret it, detail it and extract from it the underlying idea that allowed the conjecture to be solved. Price didn’t know he had the solution until his friend read it, and he wasn’t sure until Tao confirmed it. The official repository of AI contributions to Erdös problemsmaintained by Tao himself on GitHub, classify the result as a solution generated in human-AI collaboration, not as a solution developed solely by AI. The distinction is important. A previous scandal. A few weeks ago Sebastien Bubeck, a researcher at OpenAI, posted on X that GPT-5 had “solved” several Erdös problems. That publication exceeded 100,000 views, but the mathematical community and also that surrounding the AI ​​industry criticized that statement. Demis Hassabis, CEO of DeepMind, called that statement “shameful.” What had actually happened is that the model I had found solutions to already solved problems on the web. Bubeck finished deleting the original tweet and tried to back down, but all this raised doubts about the validity of the application of AI to solve mathematical problems. AI and the mathematical success rate. Terence Tao and Nat Sothanaphan maintain the aforementioned record of all AI contributions to Erdös problems on GitHub. Each of the entries in that list or table is classified with a traffic light: green for complete solution, yellow for partial progress, and red for failure. In the category of completely AI-generated solutions with no known prior literature there are three green, fourteen yellow, and eight red traffic lights. However, the repository itself adds a unique comment: those who try to use AI to solve these problems and fail do not usually report it, so it is likely that AI has been applied “silently” to a large number of these problems without success, and those attempts do not appear in any table. There is a clear bias here because only successes generate headlines. Trying to measure what matters. In February 2026, eleven mathematicians created the initiative “First Proof“. In it they included ten mathematical problems that arose naturally in their research projects. For each one they included encrypted answers uploaded to a verification site, and they gave the AI ​​systems a week to try to solve those problems that had never appeared in any training data set. Preliminary results indicate that today AI models cannot overcome that barrier autonomously, and what happens is that there are still limits to what AI can really contribute in mathematics. But then, is there a revolution or not? Terence Tao offered a clear explanation as to why GPT-5.4 had succeeded where others had failed for 60 years. What had happened was what he described as a collective blockage of the mathematical community, because everyone started from the same origin because it was “the natural one”, the one marked by tradition. The AI ​​didn’t know that was the “correct” way to start, and that ignorance turned out to be an advantage. It’s not that the AI ​​was smarter, it’s that it had no biases about how to approach the problem. Now it remains to be seen if this novel way of trying to solve problems in unorthodox ways works. This will confirm whether what happened with Erdös’s problem number 1196 was an isolated case or whether a 23-year-old boy has managed to change our vision of how to tackle mathematical problems.

The Xlean TR1 changes robot hand vacuum cleaner in a second. The most interesting thing is that he learns from you

by

A robot that learns from you, who observes how you clean and then replicates your movements to do the job on your own. This is how the TR1 is presented, Xlean’s first modela startup formed by experiencers with experience in DJI and Roborock. This device combines two functions in a single body: it is an autonomous vacuum and hand vacuum cleaner, capable of becoming a second. According to Yanko DesignThe company wants TR1 to be much more than another appliance: it raises it as a step towards domestic robots capable of adapting to each home. The launch of the TR1 arrives at a time of effervescence for domestic robotics. In the IFA 2025 fair we have seen bets like the DREAME CYBER X.which incorporates Quadtrack technology to climb stairs, or LG’s “invisible” robotdesigned to hide under the sink and always keep the mop. Faced with these proposals, Xlean seeks to differentiate himself. The startup, founded in 2022 and backed by the Robotics Institute of Hong Kong UniversityHe wants to open a new chapter in the sector with a more ambitious idea. UU device that mixes instant transformation and adaptive intelligence The TR1 key is in its ability to move from autonomous robot to hand vacuum cleaner in the blink of an eye. This change is made through an electrical blocking system that Release the main module with a single gesturedesigned to act instantly in front of any unforeseen. The startup says that this design is not only practical, it also serves as a gateway to the learning system. In manual mode, the device collects data on how the user cleans and transforms those records into patterns that applies later when it works autonomously. The manual TR1 mode is the basis of what Xlean calls “self -evolve intelligence.” Thanks to an RGB-D camera, a green laser sensor and motor encoders, the device records in detail how the user addresses cleaning tasks. The company states that these data are anonymized before being sent to the cloud and that its collection is always carried out with explicit consent, although that protection remains a promise that will have to be checked. Unlike what it might seem, learning is not immediate or limited to each team. According to Xleanthe information obtained is used to train artificial intelligence models that, in theory, benefit the entire user base. The advances would be incorporated into new versions of the software distributed by OTA updates, so it is not clear when or how real improvements will be perceived in each home. To reassure users concerned about their privacy, the device integrates a physical shutter that blocks the camera and offers a visual confirmation that it is not recording. For its proposal to work, the TR1 needs real cleaning power, especially in manual mode, when the user faces the worst spills. Xlean has developed a system called Dual-Motor Directsuction, which combines a high pressure suction with 800 rpm rollers to aspire solids and liquids at the same time. The company ensures that this design prevents the remains from spreading, thanks to Vortexmatrix technology, perfected after three years of tests and 40 prototypes. Yanko Design points out that these figures are ambitious, although it still remains to verify its effectiveness outside the laboratory. The TR1 also bets strong in navigation. Its square design allows you to clean corners with an accuracy of up to 6 mm, a weak point of traditional circular robots. According to the company, the device is able to map a 150 -square -meter house in just three minutes and Recognize more than 400 types of obstacles Thanks to a combination of vision and identification by Lidar. Xlean ensures that this performance is the result of millions of simulated scenarios and that its reinforcement learning software is prepared to move without being trapped. These promises must be validated in real evidence, but point to a remarkable advance. Xlean has also designed the Omni Station as a key complement to the TR1. The base includes an emptying system that manages liquid and solid waste, something rare in the market. The company states that the station performs a complete cleaning with hot water at 60 ° C and an automatic drying to keep the equipment ready. It also offers the possibility of direct connection to the water network and the drain, which would eliminate manual deposits. In addition, the ecosystem is committed to integration with Matter and Homekit, and a modular design that will allow future extensions. As we say, the TR1 has been presented in IFA 2025, but its future is far from assured. Xlean states that he will soon launch a Kickstarter campaign To bring it to the global market, a habitual strategy between startups that seek financing and validation before producing on a large scale. Promises are ambitious, however, there are important unknowns, from their real autonomy to the cost of consumables and the reliability of updates. Everything will depend on how the public responds to this first test of interest. At the moment, the company has not revealed the price of the device.

The influencer María Pombo defends her right to not read. And incidentally, raises an interesting controversy about habits

by

The latest statements by María Pombo (influencer pioneer With great impact on the fashion world and more than three million followers on Instagram, where its empire of family spin-offs to kardashian and ramifications of all kinds) have made half the Internet Hispano Clame: “influencer To your influences“. Some unexpected and reckless reflections on reading habits have put it in the eye of the hurricane, but they have also placed an important issue on the table: is it so necessary to cultivate the reading habit? María Pombo does not read (almost). That has recognized in A video on Tiktiok To respond to a user who criticized the bookcase he had shown in a previous video. “The bookstore is precious. But if it were full of books that have been read, it would be much more. Now I see only,” said the commentator. Pombo has tried to defend himself with a “I will say it: I think you have to start overcoming that there are people who do not like to read. And you are not better because you like to read” And he adds: “They all instilled the reading at some point in our lives, and we all had to try, but there are people who like and people who do not.” And he puts his two sisters as an example: “I have one that is also influencer and devours books; And yet my other sister, That is a pilotone has not read in his life, I believe. ”Of course, the criticisms that have multiplied in successive videoswhere Pombo has taught, to exculp Influencers His friends. The inheritance chases her, but she is faster. Paradoxically, and this is a detail without more importance than underlining the irony of the situation, María Pombo is a great -great -grandson of the novelist, journalist and translator Santanderina Concha Espinawhich in 1926 was about to win the Nobel. And it is also familiar (distant, yes) of the Cervantes 2024 AwardÁlvaro Pombo, grandson of Maria Pombo’s great -grandson, The designer Ana de Pombo. Without a doubt, a singular and respectable lineage for someone who has generated a controversy right in the opposite direction. María Pombo is the symptom. Without a doubt, the most conflictive statement of María Pombo is one that says that “you are not better because you like to read.” It gives off a anti-intellectual thinking that engages perfectly with the current era: We live counter-cilestized timesthat foster a vision in which each cultural or social group claims its own “truth” exclusive, which makes it difficult to dialogue and critical thinking. The Emotions -based policy and post -truththat normalize the lie, manipulation and extreme polarization, make communication less truthful and the least valued rigorous thinking. All this encourages Simplist and conspiracy speeches derived from … people read less. Force or respect. The important thing is that the attitude of María Pombo puts on the table a conflictive issue: should we force the taste for reading or respect the variety of interests? An issue that has generated academic positions of all kinds. For example, A 2024 study It emphasizes that reading habits, influenced by the interests and self -efficacy of the student, are positively related to the development of cognitive skills. However, Another 2023 study That reviews the relationship between reading habits, study skills and academic success, indicates that intrinsic preference and motivation are key, and that imposing rigid readings can be counterproductive. In general, we all agree (even María Pombo, even if he does not express it with total clarity): Reading is an intellectual activity of positive effects. But it is also true that the creation of environments rich in reading stimuli are necessary to develop the reading habit. A 2020 study He talked about the fact that the variety and freedom in the choice foster the interest than the imposition, and that position seems to defend Pombo. Let each one do what they want is important, but you don’t have to lose sight of what results objectively more beneficial.

Openai has just launched his new programming agent. The interesting thing is what you can do when nobody looks

by

Artificial intelligence (AI) currently presumes a leading place in the world of programming. More and more software developers resort to AI systems to write code, correct errors or automate repetitive tasks. Openai is betting again for this area with Codexhis new agent. It is a prior view phase tool that acts as a virtual collaborator. Its engine is Codex-1, a variant of O3 adjusted to better understand the needs of modern development. Among their promises are to generate more orderly code, follow instructions with greater precision, among other advantages. How does Codex work? Codex is not a simple assistant that suggests fragments of code. It is a software agent that operates in the background from the cloud. Once connected to your account GITHUByou can access your repository, read files, propose changes and execute tasks such as writing new functions, correcting errors or throwing tests. All this does it autonomously and safely, within an isolated environment (a kind of virtual cloud computer) that simulates your development environment. This should not only protect your system, but also allows Codex to execute tasks without affecting your local workflow. While he works, you can continue using your computer normally. The interesting thing is that it does not execute a single action in turn: it can take care of several tasks at the same time. For example, you can ask you to check a part of the code or Look for mistakes In another section of the project. Each task is managed separately and Codex will inform their real -time progress, allowing the user to review them. The tool is designed to adapt to the way of working of developers. In fact, it can be guided by specific files called agents.md, a kind of instruction manual that allows you to indicate what style follow, how to launch the tests or what practices should be respected within the project. Although Codex has just launched in preview, it is not an unfilming experiment. Openai engineers themselves have been using it for months as part of their workflow. So that? For Automize repetitive tasksrename variables, write tests or outline documentation. The system is also being tested in companies such as Cisco, where they seek to accelerate the development of new ideas, and in temporary, which uses it to purify errors, write automated tests and reorganize large code bases. OpenAi’s recommendation after this first round of tests is clear: assign well -defined tasks, launch several in parallel and experiment with different types of requests. Because the key is to find the exact point where the agent can display his full potential. Codex works remotely, but does it within a controlled environment. As we said above, each task that executes takes place in an isolated virtual machine, without direct Internet connection or access to external services. It can only interact with the code that the user provides and with the tools that are pre -installed using a configuration script. In addition, Openai ensures that he has trained Codex to identify and reject instructions oriented to the creation of harmful software, as tools for Hacking or malware. In any case, we must not lose sight of the fact that this proposal remains a product in research phase, with many aspects to improve. And it is still a generative AI: you can make mistakes or misunderstand certain instructions if the context is not well defined. Openai plans to introduce gradual improvements, such as the possibility of interacting with the agent during tasks, receiving more detailed updates or integrating it with tools such as incident managers. If you want to start trying Codex from today, you must keep in mind that it is not yet available for all users. For now, OpenAi has begun to deploy the tool Among the subscribers of the plans PRO (200 dollars per month)Enterprise and Team. According to the company, the users of the plans Plus and Edu will have “soon” access. Images | OpenAI In Xataka | Saudi Arabia has signed a check of 7,000 million dollars for Nvidia.

We have just found a terrestrial lichen capable of living and prospering in Mars. And it is more interesting than it seems

by

In the mid -2010, a group of European researchers They went up to the highest, arid and aggressive part from the Sierra de Gredos to collect lichens. Their intention was clear: bringing them to space and seeing what happened to them. And they did. The Castilian lichens did not travel alone, they went with another lichene of the Alps and with a pair of cryptondolitic fungi of the dry valleys of McMurdo, in the Antarctic region of Victoria Earth. 18 months passed outside the International Space Station. AND They survived: They survived the void of space, lack of water, at external temperatures and radiation. It was excellent news. But there was a better one. Because it was not the only experiment they were doing. Actually, half of the samples traveled to the US, yes; But the other half They got into In a laboratory here on Earth and were preserved in conditions very similar to those on the surface of Mars. We talk about “temperature fluctuations between -21.5 and +59.6 ºC, cosmic-galactic radiation of up to 190 megrays, and a vacuum between 10-7 and 10-4 pascals.” After that year and a half of experiment, when comparing the samples, the specimens exposed to the Martian conditions had twice as much metabolic activity as those who had been in spatial conditions. In the case of alpine lichen (Xanthoria Elegans) It was 80% more. It was interesting, but it wasn’t enough. But do they only survive or advance? Now a Polish research team has managed to take the steps that were missing. His idea was also simple: studying the physiological and biochemical responses of certain species of live and direct lichens.
