Turning off notifications 24/7 is no longer rude, it’s the new technological self-care

by

In 2026, hyperconnectivity has reached unprecedented levels. However, in the midst of this constant noise, a paradoxical cure has emerged: ignoring those we know and love has become the new secret to a happy and peaceful life. As the magazine details Wiredwe are witnessing the rise of a digital tribe known as the “maximalists of the Do not disturb“. They are users who have decided to keep their phone notifications silenced 24 hours a day, seven days a week. What was once considered a serious breach of the social contract—the tacit obligation to always be available—is now a viral trend. On platforms like TikTok, videos celebrating “monk mode” or the non-stop use of “Do Not Disturb” mode rack up millions of views. In the comments, the debate rages: while some applaud it as the definitive act of self-care, others criticize it as a terrible lack of respect for others. What has happened to our availability? The norms of social etiquette have changed drastically over the last fifteen years. If at the beginning of the last decade the golden rule was “don’t call anyone after 10 pm”, the current rule seems to be “don’t call anyone, ever”, as I already warned The New York Times. Telephone calls without prior notice by message or email have come to be considered intrusive, uncomfortable and even alarming; Nowadays, if the phone rings suddenly, we instinctively assume that a misfortune has occurred. To stop this intrusion, users have taken the tools of their own operating systems to the extreme. The technical difference that has facilitated this radicalization is key: while the traditional silent mode turns off the tones but allows the screen to continue lighting and vibrating, settings such as “Do Not Disturb” mode or “Sleep Mode” act at a deeper level of the system. These tools block vibration, dim the screen light, and hide visual alerts, eliminating any physical interruptions. According to account Wiredfor many this habit began as a survival mechanism during the 2020 pandemic, when their entire lives were reduced to the screen. After discovering the peace it brought them, they decided to never turn on the notifications again. Personal limits versus social cost. Living in a silent digital limbo has profound psychological implications. Turning off notifications is a declaration of autonomy; Those who do so are not building a wall to isolate themselves from the world, but rather installing a “door” that they only open when their schedule and mental health allow it. But this position requires paying a social toll. Announcing that you live in “Do Not Disturb” mode is almost like declaring that you were vegan in the 90s: it is often perceived by those around you as a self-righteous or rude attitude. Friends, partners, and family members often get frustrated when they don’t receive immediate answers. For this reason, the maximalists of silence have learned that preventive communication is key to explaining that this is not a personal attack, but a necessary barrier. Paradoxically, this digital isolation improves relationships in the physical world. By not paying attention to a bright screen that demands their attention, these people demonstrate an absolute presence in face-to-face conversations, generating bonds of greater depth and trust. Expert support. Science supports this need for disconnection. The cost of always being available is very high and directly affects our mental and cognitive health. The studies warn of three major impacts: Symptoms of inattention and hyperactivity: An investigation, published in Proceedings of the 2016 CHI Conference on Human Factors in Computing Systems, has shown that constant interruptions caused by smartphones can cause symptoms of inattention and hyperactivity—associated with ADHD—even in the general population that does not suffer from this disorder. Simply having alerts on maximizes these interruptions and increases inattention levels. Stress due to job fragmentation: A study of University of California, Irvine revealed that when people are constantly interrupted in their tasks, they try to compensate by working faster. However, this accelerated pace comes at a severe price: one experiences increased workload, higher levels of stress, frustration, time pressure, and tremendous mental effort. Cognitive leaks: Adrian Ward, professor at the University of Texas, ensures that cognitive ability It is significantly reduced just by having the smartphone within reach, even if it is turned off. Added to this is that each notification causes “cognitive hiccups” of about seven seconds, splintering our attention. Once concentration is broken, it can take the brain more than 23 minutes to regain it. The digital paradox. Despite its benefits, silencing your cell phone is not a panacea for everyone. Previous research suggests that, for some people, turning off alerts can cause anxiety about missing something important (the well-known FOMO). This anxiety causes users to interrupt themselves more frequently to check the screen, resulting in a net increase in distractions. At the same time, the trend has been quickly absorbed by the market. An article from Guardian criticized how “productivity gurus” on TikTok they had commodified the #monkmode (monk mode), selling it as an isolated and somewhat melancholic self-optimization formula, forgetting that the human mind also fights against forced hyperconcentration. Finally, we come to a technological irony of our time. Recent clinical protocols, like the essay published in Frontiersevaluate the use of mobile applications mindfulness (like InMind) to combat work stress, burnout (burnout) and improve the engagement of office workers. In the middle of 2026 we depend on applications within our phones to cure the anxiety that that same device generates in us. The rebellion of silence. As we move into 2026, putting your phone on permanent silent has gone from being a simple setting in the settings menu to becoming a statement of intent. As they conclude in Earthis a reminder that human attention is a finite and extremely valuable resource, to be spent by conscious choice and not by the beep of an algorithm. In the end, as summarized by the testimony collected by Wiredgiving up immediate availability in the era of “always connected” is perhaps the most peaceful … Read more

The chip industry has its own Lego black market. ASML created it by accident

by

Rick Lenssen works as a data analyst at the Dutch company ASML and builds Lego models on the weekends. It could have remained there, a mere hobby shared with his children if the company that employs him did not design and manufacture the lithography machines necessary to produce microchips, one of the key elements of current technology and one of the key suppliers of TSMC, Samsung or Intel. Now, his Lego designs imitating the original machines reach four-digit figures on eBay. 380 million in 851 pieces. It appeared in the ASML online store at the end of November 2024: a Lego model called TWINSCAN EXE:5000, measured 35 centimeters long and cost $227.95. It reproduced the high numerical aperture extreme ultraviolet (High-NA EUV) lithography machine that the company delivered to Intel in late 2023 and that allows chips to be printed from its 2 nanometer node. The actual equipment weighs 165 tons, has more than 100,000 parts and had to be transported in three Boeing 747s. The Lego set reproduced it in the style of the popular toy brand, it included a purple ray that represented ultraviolet light and a minifigure with the full clean room suit that technicians wear. The product sheet, perhaps anticipating what was to come, already warned that multiple orders from the same customer would be cancelled. Brick Lenssen. This is the nickname given to Rick Lenssen, a 39-year-old company employee who became interested in Legos. by chanceafter taking his children to a toy fair in the Netherlands. His first personal project was an exact replica of the ASML campus in Veldhoven: two years of work, 2,500 euros out of his pocket and 25,000 pieces, with details as obsessive as the peregrine falcon that nests on a roof of the complex, accompanied by a pigeon that, according to him, acts as food. He designed everything first on the computer and assembled it in the attic of his house. Where do I put this. Lenssen then encountered a drama that will be familiar to any Lego fan: what to do once you finish building the set. He offered it to the campus itself, but they didn’t want it. Lenssen wrote to ASML’s CEO on a Friday night, and within hours he wrote back saying he loved the set. To get the model out of the attic, it had to be dismantled piece by piece (like the real ASML machines), and company workers loaded it into a van. Today it is the first thing visitors see when they arrive at the company’s reception. It’s official. The jump to merchandising officer arrived later, with a model of the skyline of the campus in charge of promoting an internal app, and then the two models of machines. He was not the first: Jeroen Ottens, an ASML engineer who had worked at Lego, I had modeled a previous version. The cheapest model in the current range, the TWINSCAN NXE:3400C, at $166.70, was not born as a commercial product either: it started as internal training tool before becoming a special edition open to the public. It took Lenssen a few weeks to design the current two sets, one with a 61-page instruction manual. Your only compensation is a copy of each model. Employees only. The sales policy is one unit per person and verified ASML email is mandatory. For weeks, some fans managed to place orders bypassing that restriction due to a security hole in networks, and measures had to be taken: in December 2024 ASML began canceling orders from buyers without an actual corporate email. The EXE:5000 file even disappeared and can only be consulted today through the Wayback Machine. The same corporate email restriction covers the rest of the merchandising of the company, yes, much less coveted: sweaters, mugs, pins and Christmas decorations. eBay fever. Of course, speculation was not long in coming, as It usually happens with Lego sets that disappear from the market. Individual sets of those designed by Lenssen have been seen for $600, while the complete collection reaches $4,500. Before closing that section of the store, ASML sold 1,355 units of the latest model (there are 44,000 company employees, possibly not all of them interested in building with toy blocks). Although the comparison is absurd, only six of the real machine have been sold. In Xataka | The great fear of the US is that ASML’s UVP machines will continue to arrive in China. So he is going to intensify his trade war

that the only one with missiles is Iran

by

For weeks, Allied commanders did not understand why their most advanced systems were unable to intercept all the projectiles falling on the cities. The surprise was enormous when they verified that, in full Gulf Warsome were enough few Scud missiles thrown irregularly to force deploy huge resources defensive forces and alter the pace of an entire military campaign. The mathematics of missiles. After weeks of war, the confrontation in the Middle East It has ceased to be just a question of military capacity and has become a problem of specific inventories, with figures that condition any future decision. CNN counted through the last CSIS analysis that the United States has already consumed about 45% of its Precision Strike Missileabout 50% of the THAAD interceptors and Patriot, in addition to approximately 30% of their Tomahawks and more than 20% of the JASSM. In other words, although these levels do not prevent continued operations in the short term, they do significantly reduce the ability to sustain another high-intensity conflict in parallel, especially against an adversary like Iran. It’s not shooting, it’s replacing. The replacement of these systems introduces a clear boundary: annual production barely reaches about 100 Tomahawk units and less 500 JASSM-ERwhile interceptors like SM-3 or SM-6 They have even lower rhythms. Even with contracts to expand production, the period to recover previous levels oscillates, according to the Pentagonbetween three and five years. In practice, this means that every current launch has a future strategic cost, because there is no quick way to replace it in the event of escalation. Iran maintains the volume. Faced with this wear and tear, analysts from the Pentagon itself have assured that Iran preserves thousands of missiles ballistic and cruise, although many require reconditioning or have failures resulting from hasty modifications. Plus: problems in aerodynamic stability, propellant wear or changes in guidance systems (such as the transition to BeiDou after GPS interference) have reduced accuracy in some cases. Even so, they said that the volume is still sufficient to maintain launch rates for weekswhich introduces a saturation factor that complicates any defense. David Sling Defenses to the limit. The impact of that pressure has already been seen in the intensive use of interceptorswith systems like David’s Sling o Arrow 3 operating near critical levels. In fact, several analysts said that, in some scenarios, the reserves would not allow a continuous defense to be sustained. beyond 72 to 96 hours without immediate replenishment. It is not a trivial fact and, in fact, it would change the logic of the conflict, because even with advanced systems, a prolonged defense depends directly on the interceptor availabilitynot only its effectiveness. Operational limitations if resumed. The data that handles Washington They talk about a scenario where, if the war were reactivated, the United States would have about 2,800 to 3,000 Tomahawk and little more than 400 long-range guided bombssupported by aircraft carriers and destroyers, but with clear restrictions after prior consumption. For example, the use of less advanced munitions like the JDAM would imply greater exposure of aircraft to enemy defenses. In addition, logistical factors such as fuel arise here (with reduced European reserves around 20%) that would limit the duration of an intensive air campaign. The strait as added pressure. In parallel, Iran is clearly demonstrating ability to challenge the blockade in the Strait of Hormuz, maintaining exports through oil tankers that avoid control by turning off transponders and indirect routes. Despite interceptions and diversions of more than 28 vessels, dozens of cargo ships and oil tankers they have managed to crosswhich shows that maritime control is not absolute and that Tehran retains room for economic and strategic maneuver. The great unknown. If you like, the result of all these factors is a scenario very different and disturbing for Washington, one where, after weeks mass consumptionthe United States enters a possible resumption with limited inventorieswhile Iran, despite its failures, continues to have sufficient volume to sustain throws. There is no doubt, that at least partially reverses the usual logic, because the risk for the United States is no longer just what it can launch, but what Iran can still continue launching day after day in a second part of the war where the dictates the missiles can change name.

why the USSR was obsessed with a planet that literally ate its machines

by

There was a time when it was thought that Venus would be a good planet to explore or even terraform. After all, it is close to Earth. Carl Sagan himself made a theoretical proposal to adapt this planet for human life. Therefore, it is not surprising that it became one of the biggest objectives of the Soviet Union (USSR) during the beginning of its space race. With the Venera missions, dozens of probes were sent to explore the neighboring planet. A few were enough to prove that it was a more inhospitable place than one thought. However, that did not make those scientists give up their efforts. Only 16 named probes. Between 1961 and 1984, The USSR sent 28 probes to Venus. Only 16 of them, those that partially completed their mission, were baptized as Venera. Of those 16, only 13 crossed the atmosphere of the neighboring planet and 10 managed to land. Some even survived a few minutes to transmit important information to Earth. The violent destruction of each probe provided new data that was used to improve the next one. Even knowing that the next one would also succumb, the program continued forward and laid the pillars of the space exploration technologies that came later. An inhospitable planet. Venus It is an extremely inhospitable planet for many reasons. To begin with, its temperatures are very high. Temperatures can reach 465ºC, which is why many Venera probes literally melted when they reached their destination. The pressure is also very high. It is equivalent to about 90 atmospheres and could quickly crush a submarine. Many of these probes were also crushed. On the other hand, more than 96% of its atmosphere is carbon dioxide, making it highly toxic, although that is not as problematic as the corrosive clouds of sulfuric acid that accompany it. The Venera probes also had to deal with this corrosion. step by step. The first Venera probes lost communication with Earth before even reaching Venus. Others, however, managed to transmit information from the surroundings of the neighboring planet or even on its surface. The first to send data before being crushed by the pressure were Venera 5 and Venera 6. Previously, Venera 4 had been the first probe to manage to pass through the atmosphere of a planet other than Earth. Venera 7 even managed to land and stay 23 minutes on the surface of Venus before being torn apart by the heat and pressure. Later, Venera 9 sent the first black and white images. Images of the surface of Venus taken by the Venera probes Special mention to Venera 13. Possibly the greatest advances came with Venera 13. Although it was planned to last 32 minutes, the probe stayed on Venus for 127 minutes before disappearing like all the others. There he managed to take photographs much more advanced than those of Venera 9. He also measured the composition of the atmosphere and used a lightning detector to measure the electrical activity of Venus. It was even able to analyze the winds thanks to its built-in anemometer. Along with Venera 14, it was possibly the probe that provided the greatest discoveries before disappearing like all the others. 40 years later. With the Venera missions, the USSR verified that, in reality, Venus was a planet too inhospitable for exploration. But knowing our neighbors can help us know ourselves. For this reason, despite knowing that it was all suicide, 28 probes were sent, with landing, chemical analysis or image taking technologies that have continued to be used over time. Today, more than 40 years after the launch of the last probe, we can access the data obtained by many other missions that have also headed to Venus. Other missions. First it was NASA, in 1970, with its Mariner 10 probe. Although its main objective was Mercury, it also had time to explore the surroundings of Venus. Later in 1989 The Magellan mission made the first global map of the Venusian surface. Today the American agency is preparing for the launch of VERITAS and DAVINCI+, which should leave for the neighboring planet in the coming years. For its part, Europe launched the Venus Express probe in 2005 and Japan launched the Akatsuki probe in 2010. In the next decade, Europe is prepared to launch Envision, which will be in charge of studying the core of the planet. All of these missions were clearly inspired by the Venera probes. Of course, even if we can never live there, being able to send probes to a planet that melts and crushes ships is a great achievement of space technology.

Mercadona has gotten rid of its search engine and replaced it with its own. They did it in a month with Claude Code and saved 90%

by

Mercadona’s online store processes 4.4 million searches a week. Until recently, that volume was managed Algoliaa well-established search service used by companies like Sephora or LVMH. They had been with him for eight years. Now They have replaced it with their own search enginebuilt largely by José Ramón Pérez Agüera, CTO of Mercadona Tech. He has done it largely by himself, from his home, over a long weekend. This is how he told it in a successful LinkedIn post which now extends us in a video call with Xataka. “I’m going to be very honest and I know that this is going to look tacky, but it’s the truth,” says Pérez Agüera. “70% of the work (implementing the search engine, improving search quality and laying the foundation) took three days. One weekend plus an extended Monday.” The result: an 85% improvement in the quality of the ranking, the complete elimination of searches without results (previously 4% of the total) and a reduction in the monthly cost of between 9,000 and 15,000 dollars with Algolia to less than 900. That is, a saving of between 90% and 94% depending on the month. A decision that had been on hold for years The idea of ​​abandoning Algolia is not new at Mercadona Tech, it had been ruminating for a long time. The reasons are not surprising either: the search engine directly moves between 30 and 35% of the products that end up in the cart, which makes it a critical piece of business. And Algolia, like most SaaS services, has a pricing model that scales with use: as the company grows, the cost grows, with no way to stabilize it. “In the end you end up in a vendor lock-in of very critical software that is then difficult to get rid of,” explains Pérez Agüera. But Every time the team considered building something of their own, the work estimate was pushed back.. “The most optimistic vision we had, and with a much more basic version than the one we are going to release now, was five months. And it already seemed fast to me.” Then came the era of AI agents in software development. Pérez Agüera used Claude Code as the main tool and began to experiment on his own, without a formal project or assigned team. More out of curiosity than anything else. For playing. What AI did and what it didn’t The technical process combines hybrid search (by keywords and semantics) with a machine learning system that optimizes the ranking of results. AI made it possible to iterate on dozens of experiments in hours, analyze 479 MB of catalog and analytics data in days, and explore different ranking configurations by chatting with the agent instead of manually implementing them one by one. “I easily did 40 or 50 experiments in a weekend. That would have traditionally taken me weeks,” he explains. But the speed has a precise limit: the 29 technical decisions that AI did not make. Documentation generated during the experimentation process with Claude Code: the 14 parameters that Mercadona’s search engine evaluates to order results (from the popularity of a product to how well it fits semantically with what the user is looking for), its relative weight in the final ranking (popularity and semantic similarity account for two thirds of the decision) and the configuration of the machine learning model used to train it, based on click and purchase data from the last four weeks. Each of those parameters was discussed and validated with the AI ​​agent, but the final selection was made by the human team. Image provided by Mercadona Tech. The most representative was the choice of the indexing engine. Most systems, and probably any AI agent consulted, would have recommended Elasticsearch, the most widespread solution. Pérez Agüera chose Tantivy, a much smaller library written in Rust that integrates as an embedded component, without the need for a separate Java virtual machine. An impossible decision without knowledge of the Mercadona ecosystem. “The AI ​​always recommends the most generic option,” he says. “I made that decision because I have the context and the knowledge to make it.” The transfer to the team When the core of the search engine was ready, the project passed to the engineering team. What they found was not bad code, but it was ccode that did not follow Mercadona Tech’s internal standards. The architecture was hexagonal, as is the company’s style, but it used a different approach than usual. The tests existed (Pérez Agüera applied TDD during development) but some did not make sense or were missing cases. The agent had written thousands of lines of code in a few hours and reviewing them all was unfeasible. “The team’s Tech Lead took two or three days to adapt the project to our good practices,” he summarizes. “Not because the code was wrong, but because it didn’t meet our standards as a company.” In total, adding the initial phase and the launch into production, which includes load testing, infrastructure adjustment and integration into the Mercadona Online architecture; The project has taken approximately a month of work. And “two and a half people” have been in charge of it: Pérez Agüera, the Tech Lead of the Shop team and a part-time Staff Engineer for infrastructure. The original five-month estimate required five or six people. “FWe have easily done a x5 to the speed of the projectand what we have now is much more advanced than what we would have had in five months,” he says. What changes for the teams For Pérez Agüera, the search engine is one more experiment within a larger transformation that Mercadona Tech continues to process internally. The question on the table is not whether to use AI in development, but how to redesign the entire development process based on it. His diagnosis of the profiles is forceful: “AI is going to mean that fewer developers are needed and more engineers are needed. Coding loses value per se; the … Read more

buy a new Tesla

by

In April 2019 Tesla launched its platform “Hardware 3” (HW3) with an apparently blunt message: all cars leaving the factory would have, thanks to this platform, the necessary hardware for complete autonomous driving. There were many customers who trusted that promise and They spent between 8,000 and 15,000 dollars to enjoy itbut they have just found themselves in a huge bucket of cold water: HW3 is not powerful enough for unattended FSD, Elon Musk has assured. The technical reason. The HW3 bottleneck that Musk alluded to is memory bandwidth: this platform has only one eighth of the memory bandwidth that HW4 has. The FSD system is based on so-called autoregressive transformers and to be able to work with them a specific bandwidth is necessary that cars with HW3 cannot reach. There is no easy way to fix it. You cannot optimize the software or the AI ​​model: it is the chip itself that is physically limited and no OTA update can fix the problem. Elon Musk made it clear in the investor conference after the presentation of quarterly results: “I wish it were different,” he explained, “but Hardware 3 simply does not have the capacity to achieve FSD without supervision.” Millions of vehicles affected. There are an estimated four million Tesla vehicles active and on the road that are based on HW3. Of those, around 285,000 bought the FSD package. Investor Ross Gerber indicated in X that Tesla’s financial liability could amount to several billion dollars. Better buy a new Tesla. The firm has not announced refunds or compensation to those affected. What it does offer are two alternatives. The first, a trade-in (deliver your car and buy a Tesla with HW4) without giving specific financial details. The second, a free update they have called “V14-lite”, which will reach owners of cars with HW3 in June. Theoretically, this version will offer the FSD v14 options adapted to that older hardware. It is an improvement, yes, but not what was promised for users who have been stuck on FSD v12.6 for a long time. Complex modification. Musk too speak They will offer the ability to upgrade the car to replace the HW3, but the cameras will also need to be replaced. “To do this efficiently, we will have to create microfactories in big cities to do it efficiently. Everything is done in the technical service. It is extremely slow and inefficient to do it. I think over time what makes sense for us is to convert all the HW3 cars to HW4, because that is what will allow them to enter the robotaxis fleet and have unsupervised FSD.” Versions for some, versions for others. While these models were progressively left behind in the support of FSD versions, the new models equipped with HW4 have been able to enjoy FSD v13 and FSD v14, the most recent and powerful versions of this driving assistance software. In fact, we were able to test FSD (Supervised) a few days ago, an FSD v14 version of this system. In Europe there are also affected. In Europe there were also users who purchased Tesla’s FSD package even without being able to use it legally on European roads. One of those users, Mischa Sigtermans, is a Dutchman who bought his model 3 in 2019 waiting for FSD’s promise to be fulfilled and paid 6,400 euros for it. Seven years later he finds that the FSD (Supervised) mode has finally been approved in his country, but he cannot use it because his car is HW3. has created a website for Europeans affected by the problem and has received 3,000 registrations, which represents six million euros in FSD purchases.

the “cannibalization” of energy

by

Spain has held an indisputable title for years: it is the European leader in the signing of green light ‘mega contracts’ for large companies. However, this gold medal hides a dark side, a true paradox of “dying of success.” While the continent suffers the blow of the very high costs of fossil fuels due to the conflict in the Middle East, the avalanche of solar panels in our country is bursting the market from within. According to the data provided The Newspaperthe prices of these long-term agreements (known as PPAs) have fallen by 13.5% at the start of 2026 alone. The megawatt hour (MWh) stands at around 32 euros, marking historical lows and being cheaper even than in the worst moments of the economic stoppage due to the pandemic. The ghost that walks through the sector. The word that resonates in the offices of the energy sector is “cannibalization.” The immense solar capacity installed in the country generates a traffic jam: in the central hours of the day, when the sun shines at its maximum splendor, all producers pour their energy at the same time. This brutal excess of supply compared to demand causes prices to sink. The chaos is evident if we look at the figures. Five Days points out that in the first quarter of the year Almost 130 hours have been recorded with negative prices. This is destroying the value of PV projects on paper. According to the same newspaper, the price of a photovoltaic megawatt “ready to build” has plummeted from the 150,000 euros it cost four years ago to less than 30,000 euros. For large corporations, contracts are being signed at “knockdown” prices of between 15 and 20 euros. From promoter bankruptcy to national shield. The business is no longer a bed of roses. As explained in Five Daysthe drama for the promoters is that there are almost 53 gigawatts of solar energy with connection permits granted that “are not producing.” That is, there is more power paralyzed or waiting than what is currently installed and operating (52 GW). Faced with this panorama, and with interest rates skyrocketed by geopolitical instability, banks have turned off the financing tap. Those who entered the renewable “boom” late and without financial muscle are now facing bankruptcy. But here comes the paradox. The promoter’s drama is the country’s lifeline. While the European energy bill has increased by 24 billion euros due to the crisis in the Middle East, Spain’s strong renewable generation sank the wholesale price by 20% in March. The President of the Government, Pedro Sánchez, took advantage of this “green pragmatism” against the “dogmatism of fossil fuels”, ensuring that the ultimate goal is for Spain to offer its industry “the cheapest electricity in the world.” So what’s going to happen now? The sector is forced to mutate. The analysts consulted by Five Days They are blunt: photovoltaics alone are no longer of interest. The future lies in hybridizing plants with wind energy or, as he also points out The Newspaperinstall large batteries (BESS systems) to store that cheap midday energy and sell it at night. Meanwhile, in a troubled river, fishermen gain. With small and medium-sized developers drowned, large Asian investors and long-term funds are taking out their checkbook to buy projects at bargain prices. For their part, buyers and sellers are introducing new clauses in contracts to protect themselves against unforeseen fluctuations in the market. The European contrast: Brussels asks to accelerate. While Spain deals with its own solar crisis, Europe is desperate to accelerate its transition to escape foreign dependence. The European Commission has just presented your plan AccelerateEUwhich aims to provide immediate relief to consumers and accelerate clean deployment. Brussels’ emergency recipes include tax cuts on electricity, reducing the price of public transport and prohibiting supply cuts to the most vulnerable families. In addition, the EU requires maximizing existing renewable infrastructure and improving the network. On a national level, Sánchez has committed to the sector that connection to the network “will not be the obstacle” to developments. Tame the turbines. Spain has won the solar installation race by far, but now faces a painful maturity crisis. The great technical and economic problem is no longer how to generate clean energy, but what to do with it so as not to destroy the very market that supports it. In the current and turbulent global geopolitical scenario, the dilemma posed by the Executive is unappealable: either we choose “turbines, or turbulence”. Spain’s immediate challenge is no longer just to plant more panels, but to tame those turbines so that they stop devouring each other.

in DeepMind they use Claude, the rest of Google engineers want to and cannot

by

Things are hectic at Google. In recent months, some DeepMind engineers have had access to Claude Code and Anthropic models, but in many other parts of the company this tool, which is currently considered the best on the market, has been banned. This has caused strong internal tensions in the company, and is also a sign of something worrying: Google’s AI cannot compete with Anthropic’s at the moment. what has happened. Steve Yegge is a software industry veteran who worked for years at Google. Last week posted a viral tweet in which he explained that after speaking with a current manager, he was concerned about the adoption of AI tools in this company. “The bottom line is that Google engineers have about the same adoption of AI as John Deere, the tractor company,” he said. Or what is the same: one of the most cutting-edge technology companies in the world was being anything but cutting-edge in its use of AI. Demis Hassabis gets angry (and a lot). Recent Nobel laureate Demis Hassabis, head of DeepMind, criticized Yegge’s tweet and told him to stop spreading nonsense. “This publication is totally false and is simply clickbait,” he said. Yegge returns to the fray. The engineer spoke in the following days with more current Google employees and discovered more things that he told in another long tweet. According to their conversations, the internal adoption of AI at Google follows a conventional pattern: 20% reject it, 60% use it in a basic way, and 20% take advantage of it intensively. Either you let me use Claude Code or I’m out of here.. But there was something else: some engineers are prohibited from using Claude Code because it is a competing product, but the vast majority do not have access to those tools because the company wants them to use Google’s tools — that is, the Gemini models in Gemini CLI, its alternative to Claude Code. According to Yeggewhen they tried to force DeepMind engineers to stop using Claude Code and Anthropic models, they refused to stop using the tool and threatened to leave the company. Internal sources of the company confirmed the data published by Yegge in a published news on Business Insider. Sergey Brin gets going. This week, The Information public that Sergey Brin has sent an internal memo to DeepMind engineers and researchers and confirms what was already being said. “To win the final sprint, we must urgently close the gap in agentic execution and turn our models into world-class developers,” the Google co-founder wrote. According to this data, an “assault team” has been created with the direct participation of Brin himself and DeepMind’s CTO, Koray Kavukcuoglu. That statement makes it clear that Gemini is below Claude in capabilities, because otherwise there would be no talk of “closing the gap.” Google and fragmentation. It’s not just that Claude Opus and Claude Code are now better than Gemini and Gemini CLI. Es que además esto ha dejado claro que en empresas tan grandes como Google la fragmentación operativa puede llegar a ser un problema grave. That some can use something that others cannot, and that worse tools are forced just because they are their own, can end up generating internal tensions, as has happened. That is what Google now seems to want to remedy so that all its employees row together. Another victory for Anthropic. All this controversy does nothing but favor Anthopic, which has managed to take the lead in this race – rather marathon – of AI. That the engineers at the prestigious DeepMind prefer their AI platform to Google’s own is an unequivocal sign that today Anthropic is ahead for AI experts.

We finally know when their 1.2 and 1.3 nm chips will arrive

by

TSMC has revealed which photolithography will be ready for large-scale chip manufacturing over the next three years. The largest producer of semiconductors of the planet has made its itinerary official just a few hours ago during its North American Technology Symposium, which was held yesterday in Santa Clara (USA). And the technologies it has presented put an unappealable reality on the table: this Taiwanese company is determined to continue leading the integrated circuit manufacturing industry. To achieve this in 2029, it will have the A12 and A13 integration technologies ready for large-scale production, which are nothing more than derivatives of its A14 photolithography. From a commercial point of view these will be TSMC’s first 1.2 and 1.3 nm technologies, although it is important that users do not overlook that nanometers no longer faithfully reflect the length of the logic gates or another physical parameter, such as the distance between the transistors. Each chip manufacturer handles them very freely, which prevents users from directly comparing the lithographs they try to “sell” us. The disconnection between the nomenclature and the physical reality of integrated circuits is now almost absolute, but nanometers are still useful to identify the degree of development of each photolithography within the portfolio of each semiconductor manufacturer. Having said this, it is worth investigating what TSMC is preparing. A technical feat: A12 and A13 without using ASML’s High-NA machines Kevin Zhang, TSMC’s deputy chief operating officer, has clarified something very important: “I am amazed by our R&D team. They continue to find ways to drive technological development without using ASML UVE High-NA equipment. Someday we may have to use them, but right now we can continue to reap the benefits of current EUV technology without moving to High-NA which, as we all know, is extremely expensive.” That’s impressive. TSMC is going to continue developing very competitive lithography over the next three years without resorting to High-NA machines. The A13 lithography will be the result of the refinement of the A14 In the slide that we publish below these lines we can see that in 2028 TSMC’s most advanced lithographic node for the consumer market will be the A14, which will use GAA transistors (Gate-All-Around) second generation. Mass production of consumer chips with A13 lithography will start in 2029 and will take A14 integration technology as its base platform. This simply means that the A13 lithography will be the result of the refinement of the A14. According to TSMC, the A13 integration technology is an optical optimization of the A14, which in practice will allow it to achieve a 6% higher transistor density while maintaining compatibility between the two. On the other hand, N2U lithography will arrive in 2028, which is also aimed at the consumer market. It will be an extension of the N2 platform (2 nm) and will deliver performance, again according to TSMC forecasts, between 3% and 4% higher than N2P, as well as consumption between 8% and 10% lower. Finally, A12 lithography will arrive in 2029 with the A13, although it will be mainly intended for chips for data centers. It will use, like A13, second generation GAA transistors and NanoFlex Pro technology. The latter will allow IC designers to use fast cells for the critical parts of the GPU that need speed, and dense or efficient cells for the rest, thus optimizing the chip area down to the last millimeter. NanoFlex Pro is one of the innovations with which TSMC seeks to protect its technological leadership with the purpose that its chip customers for artificial intelligence (AI), such as Nvidia, AMD or Cerebras, continue to turn to it and not to Samsung or Intel.
