problem

Silver is right now the most sought after and most expensive metal on the planet. And the problem is that there is not enough

by

Silver just surpassed $60 per ounce for the first time, and the impact is especially noticeable in the technology sector. The metal is essential for solar panels, electric cars, electronics and AI data centers, and demand has skyrocketed much faster than the mining industry can respond. In a matter of months, what seemed like a one-time rally has revealed a deeper problem: the world is entering a phase of real silver shortage. A record that marks a turning point. The escalation became historic this week. While this report is being written, silver is around $62.67 per ouncedoubling its value since January after five consecutive years of supply deficit. Although the rise is not surprising who follows this marketwhat impacts is its speed: according to Bloombergsilver is the best performing metal of the year, doubling its price and even surpassing gold in what is already its biggest increase in decades. But beyond the price, what is relevant is not how much silver has become more expensive, but why. The market structure has changed. Money doesn’t stop going up. For analysts and companies, this new peak has profound implications. Silver no longer behaves as a simple safe haven asset, it is a critical industrial input whose shortage can slow down entire sectors of the global economy. Unlike goldwhose function is mainly financial—, the silver it is a metal that supports electrification and the energy transition. However, the problem is amplified by the nature of the market which is narrow, volatile and without global strategic reserves. As Bloomberg recallsthere is no equivalent to gold central banks that act as a stabilizer of last resort. When physical money is lacking, there is simply no safety net. Source: TradingView A perfect storm. The rise of silver is not understood by a single factor, but by the convergence of industrial, monetary and geopolitical forces. First of all, according to Financial Timesthe silver market has been in deficit for five years, with inventories at minimum levels and production unable to respond. Silver is mostly obtained as a byproduct of zinc, copper or lead mining, making it difficult to increase supply quickly. Furthermore, the three largest producers—Mexico, Peru and China— face environmental and regulatory restrictions which further reduce production capacity. The Silver Institute foresees industrial demand increasing at least until 2030, driven by solar expansion, transportation electrification and the growth of digital infrastructure. Additionally, the global data center boom also adds to this pressure, because some of them operate with solar energy. Added to all this is a worrying dynamic: the United States has accumulated large reserves of silver due to the risk of new tariffs under Section 232. This diversion of metal to American deposits has drained inventories in London and Asia, generating a silver squeeze which skyrocketed metal borrowing costs. As pointed out in FTthe North American retail investor—for whom silver is “the poor man’s gold”—is also entering aggressively, fueling the bullish momentum. China enters the scene. The decisive factor comes from Beijing. The Ministry of Commerce of China announced in an official statement new strict conditions for exports of silver, tungsten and antimony during 2026–2027, including strengthened requirements, documentary controls and more rigorous supervision for state-owned companies that want to export metal. Likewise, the official text confirms China’s intention to protect its strategic resources for internal use, especially in sectors considered critical for its future competitiveness: renewable energy and artificial intelligence. The reason it’s clear: China wants to guarantee enough physical silver to power its own AI data centers, the expansion of which requires huge volumes of solar panels. With global mining production limited to 813 million ounces annually and new projects that take years to come online, Chinese controls could exacerbate an already structural shortage. China, the largest global refiner of silver and a central player in the solar chain, has real capacity to alter the global balance of the market. India and Russia complete the geopolitical map. On the one hand, India has become one of the great drivers of the physical silver market, with about 80% of global demand for bars and coins. According to ReutersIndian demand for jewelry and bullion has been so strong in 2025 that it has caused physical shortages and premiums on international prices during holidays such as Diwali. Added to this pressure is a new regulatory framework: India’s silver imports soared to $2.72 billion in October, partly due to measures that facilitate the monetization of physical silver, allowing consumers to convert their holdings into financial instruments. On the other hand, Russia decided at the end of 2024 start buying silver for its State Reserve Fund, a move that has contributed to skyrocketing prices against gold even further. It’s not just silver: a global reconfiguration of metals. The rise in silver coincides with a historic movement in gold. The golden metal exceeded $4,200 due to pressure from central banks, which already have more value in gold than in US Treasury bonds. A structural turn in the international monetary system. For their part, platinum and palladium have also become more expensive. This phenomenon indicates that strategic and safe haven metals are regaining a central role in the global economy. What to expect from now on. The forecasts for the coming months coincide in a common diagnosis: structural tension will not disappear, even if phases of technical correction appear. On a technical level, several analysts see room for further increases. According to FXStreetconsiders an advance towards 63.8–65 dollars plausible, supported by a weak dollar and the continuity of the buying impulse. However, since the TradersUnion portal introduce caution, the market is clearly overbought, and losing the $61.5 support could trigger short-term profit taking. Added to all this are two new forces compared to past cycles: the rise of AI, which multiplies solar demand, and China’s industrial policy, which can further restrict global supply. In this context, as analyst David Morgan warnsprecious metals are entering “a monetary inflection point,” driven by both the energy transition and loss of confidence in … Read more

AVLO’s departure from Madrid-Barcelona seemed like another problem for Renfe. He has left us an unexpected winner

by

August 2025. The summer had started out average for Renfe and ended even worse. After an exchange of information, Renfe accepted that some Talgo AVRIL trains had suffered cracks in their structures and that they were being taken out of circulation, with the consequent suspension of service. And, of course, that has had consequences for travelers. Goodbye AVLO, goodbye. Everything ended up precipitating in the last days of August but the origin must be sought a few days before. At the end of July, Renfe paralyzed by surprise the sale of tickets for the AVLO service. The news was given from The Economist: AVLO trains had suffered cracks in their cars on the Madrid-Barcelona line. A few days later, Renfe confirmed this fact and began to apply a temporary solution. The idea is that the trains would continue running but reducing traffic speed there where it was believed that the trains had cracked. Some leaked photos Already in August they demonstrated the seriousness of the events. Renfe decided withdraw AVRIL trains of the service. And days later he ended up suspending the AVLOs. September. It was a strange month for Renfe. The company maintained the AVLO service in the early stages, but in the absence of finding a solution, it ended up canceling. relocate passengers of the service low cost of the company on the AVE. That is, a kind of upgrade to travelers who already had their ticket for beyond September 8. That put the company in trouble. Or at least that was the first reading. Since then Renfe does not compete directly against Ouigo and Iryo. Without a cheaper service, the Spanish company was left without the possibility of competing directly against foreign companies. However, it does not appear to have directly affected their results. How has it affected Renfe? If we take into account the latest data from the CNMCwhich refer to the months of July, August and September, we could say nothing or very little. Renfe Viajeros (which adds data from AVLO and AVE) has increased its occupancy by 4%, the number of travelers has increased by 0.6% and they have increased the use of rolling stock by 1.6%. Regarding prices, Renfe has also won. And the company has managed to increase the number of travelers despite an obvious increase in ticket prices. The AVE cost 70.58 euros on average, 13.3% more than in the same period last year and AVLO went to 51.35 euros, repeating the same growth. Retail. But what interests us most about this period is how prices behaved when AVLO was not available. In the month of September, AVLO prices dropped but let’s remember that they were only available for very few days. Instead, Renfe only offered AVE tickets. And they were shot. In September, service prices premium increased to 75.11 euros. It is 11.4% more than the previous month. But above all, it is a price 17.4% higher than that of the same month in 2024 when there were four companies available on the market. Beyond Renfe. Curiously, the one who performed the most in this case has not been Renfe. Iryo is the company that has increased prices the most in this period. With an average ticket price of 63.82 euros, the company seemed to have positioned itself between Ouigo and Renfe, offering an alternative halfway between both services. However, the absence of AVLO in the month of September must have triggered the demand for Ouigo and Iryo. This is the only way to explain why the Italian company raised the prices of its routes to 74.13 euros in that month, just one euro less than the AVE. Year-on-year growth that month reached 83.5%. For its part, Ouigo also raised prices but remained on a somewhat more contained line. In the quarter, the average ticket price was 51.86 euros, which already represents a growth of 20% compared to the previous year. In September, however, prices remained at 52.20 euros, slightly below the month of August but, yes, 30% more expensive than in September 2024. The complete photograph. Expanding on everything that happened, as expected, AVLO’s departure from the Madrid-Barcelona corridor has only increased prices. It is something that we were already beginning to suspect and that was logical if we take into account that it is the corridor with the highest occupation and use of the line. In fact, the latter exceeds 84% ​​and remains around 10% above any other high-speed corridor with liberalized services. It is the perfect environment for passengers dynamic prices suffer.

There are dozens of influencers obsessed with helping us choose the perfect can of tuna. The problem is that what they say doesn’t make much sense.

by

There is a fine line that connects volcanic eruptions, oil combustion, and waste incineration with our kitchens: mercury. A mercury that is produced in dozens of activities (mostly human), which ends up deposited in the waters, transformed into methylmercury by millions of microorganisms, stored in fish and, finally, in our stomach. It was only a matter of time before it became the huge food scandal it is today. Methylmercury also reaches social networks. The problem is so big that there is no shortage of experts and influencers that defend messages such as choosing cans of “tuna” over cans of “light tuna.” The music is that of institutions such as the European Food Safety Authority (EFSA) that recommends avoiding large fish; The lyrics hide many problems. At the end of the day, the viral message mixes correct intuitions, with more than debatable scientific evidence (it uses, to begin with, commercial classifications that do not have direct Spanish correspondence). This is not the first time that an idea that sounds good ends up giving us headaches. And why is that a problem? Because, like it or not, fish is a centerpiece of many diets. Not only for its protein contribution, but as a priority source of certain fats that are very difficult to replace by any other means (e.g. omega-3). The thing is, with all that, comes methylmercury. And exposure to methylmercury is a tricky thing: it can harm brain development and be toxic to the nervous system. In fact, it can cause symptoms such as tremors, memory loss, and cognitive dysfunctions. The most vulnerable groups are pregnant women, nursing mothers, babies and young children. Do all fish have the same amount of mercury? No, it doesn’t. According to the Spanish Agency for Food Safety and Nutritionthere are four really dangerous species: the swordfish or emperor, the bluefin tuna (Thunnus thynnus), the shark (dogfish, mako shark, dogfish, dogfish and blue shark) and pike. These are problematic in women who are pregnant or planning to be pregnant, nursing mothers and children under 10 years of age. In fact, AESAN recommends directly avoid its consumption. The rest of the species are not problematic for the effects of mercury: they are safe and healthy. And the AESAN recommends between three and four servings a week even in the at-risk population. And aren’t there more differences according to levels? That is, are there only dangerous and non-dangerous species? No no. It is true that each species contains a different amount of mercury. In fact, each copy has different levels. That’s where the problem comes from: we need simple ‘rules’ to help us deal with uncertainty. On a practical level, according to the available studies, we can only define species with low mercury content as those on this list: Pollock, Anchovy, Herring, Cod, Bacaladilla, Cockle, Mackerel, Squid, Shrimp, Crab, Cane, Coquina, Carp, Squid, Clam, Choco/Cuttlefish, Lobster, Coquina, Sea bream, Sprat, Prawn, Horse mackerel, Lobster, Prawn, European sole, Dab, Sea bass, Mussel, Merlan, Hake, Razor clam, Oyster, Pomfret, Flounder, Squid, Octopus, Shrimp, Atlantic salmon, Pacific salmon, Sardine, Sardinella, Sardinopa, Plaice, and Trout. Everything else has medium levels and making distinctions between them is impossible on a practical level. So it doesn’t make sense to follow these types of recommendations? In general, any attention we pay to food is good. The system is configured in such a way that, if we let ourselves goour diet gets worse. However, we know that Obsessing over diet is also full of problems.. Using heuristics that complicate the purchase without substantial improvements is not as good an idea as it seems.

In the search for a supersonic train, China tests a Maglev that will reach 4,000 km/h. The problem will be maintaining it

by

China’s conquest of the high-speed train field is impressive. In the 2008 Beijing Olympicsthe country had just 120 kilometers of high speed between Beijing and Tianjin. 17 years latermanage more high-speed kilometers than any other countrya very long distance from Spain or Japan. They are not only building kilometers to unite the entire country: they are developing technologies so that the plane is no longer necessary. As? With Maglev trains at speeds of 1,000 km/h. And a specific model, the T-Flight, which dreams of 4,000 km/h. Maglev + Hyperloop. China is one of the countries, along with Japan, that is investing a lot of money in the development of the magnetic levitation trainsor Maglev. This technology allows trains not to rest their wheels on the rails, but rather to float thanks to a series of powerful magnets and an electromagnetic field. This allows us to exceed the 250 km/h that has been set as a standard for high speed and, for example, China has the fastest Maglev in the worldone that reaches 431 km/h. It is already operational between Beijing and Shanghai, but in Japan is testing one that will exceed 600 km/h. It’s a speed that will seem slow compared to what CASIC is preparing. It stands for “China Aerospace Science and Industry Corporation,” a state-owned tactical missile company that announced the T-Flight project in August 2017. The idea? Combine magnetic levitation trains with Hyperloop-style vacuum tubes. T-Flight. In short, it is putting a Maglev in a vacuum tube, eliminating air pressure and resistance as much as possible, but there is much more. For example, the idea of CASIC is that magnetic levitation is enhanced thanks to superconductors that will raise the train up to 100 mm above the rail. Conventional Maglevs are raised by about 10 mm, and the idea is that the higher the train is, the more stability it will have at extreme speeds. On the other hand, the tube itself, with a system that extracts air from it to create a low pressure environment, reducing aerodynamic resistance to the maximum. This partial vacuum and levitation that eliminates the physical resistance of the wheel and track is what will allow unprecedented speeds to be achieved. Achievements. In 2024 they already achieved one first validated test as a world record by reaching 623 km/h, but in the summer of this year, in a low pressure environment, The train reached 650 km/h in seven seconds in its laboratory. They were strange tests, since the track was a kilometer long when the usual thing is much longer, but that also gives us a clue of what brutal which is both the acceleration and braking of the train. That is, think that, in seven seconds and in just one kilometer, the train accelerated to 650 km/h and stopped. The team’s idea is to reach 800 km/h as the top speed this year, but the ambition goes much further. Ambition. Currently, the team is in Phase 1, which is the one that aims aim that speed of 1,000 km/h. To do this, and to validate the speed in real conditions, they want to extend the test track to 60 kilometers. However, the thing does not stop there and, when the project was born, it was already said that Phase 2 and Phase 3 would have as aim 2,000 km/h (almost double the cruising speed of a traditional commercial airplane) and 4,000 km/hsupersonic speeds that would compete with the fastest planes in the world. This would allow large urban centers in China to be linked in a few minutes, leaving aside the need to take planes to cover long distances. In fact, this high speed is already showing in Europe that short flights do not make sense if we combine the waiting time at the airport with the flight itself and compare it with the comfort of access to the train. A major challenge. Now, the goal will not be easy. Maglev technology works and is proven, but what they want to achieve with this T-Flight not only complicates things because, in addition to a track, a tube must be built. And, of course, maintain it. Extending this partial vacuum over hundreds of kilometers of tube represents an enormous technical challenge because it implies that the joints must be perfectly sealed, without the cold and heat dilating them so that there are no leaks. It is estimated that a 600 km pipe requires an expansion joint every 100 meters, and each one of them represents a potential point of failure. Furthermore, at 300 km/h appreciate vibrations in the seats. Air system to reduce pressure inside the tubes Furthermore, any decompression would be catastrophic and perhaps most importantly: there is no certification standard or safety protocols for something like this. In any case, T-Flight continues to take steps at a good pace and, although it seems difficult to see it working in the short term, if a country can achieve it right now… it is China.

The meteorological winter has already begun for the AEMET. And now we have another problem with the DGT beacons

by

The State Meteorological Agency (AEMET) has not waited for the solstice to start winter. A season that, meteorologically speaking, extends from December 1 to February 28. Three months of cold await us (although less and less)rain, snow and various inclemencies. This year, it is inevitable to ask ourselves if the cold may affect the V16 beacons of the DGT. The answer is a resounding yes. Resistance up to -10ºC. All approved V16 beacons must have with a series of requirements. And one of them talks precisely about resistance. There are two things to keep in mind here: the IP rating and what temperature range they can operate in. New connected beacons must have at least IP54 certification. That is, resistance to dust and splashes of water. But they must also offer adequate operation within a wide range of temperatures. Specifically, between -10ºC and 50ºC. It is enough even If we leave the car in full sun in summerbut in winter it gets a little more complicated. BUT. Theoretically, Spain is not a very cold country. But although it is not at the level of the Nordic countries, in certain places or times the thermometer can fall below -10ºC. If we are going skiing, if we are driving on a mountain road on a particularly cold day or if we are considering a getaway to one of the “refrigerators from Spain”things get complicated. For example, Molina de Aragón (Guadalajara) is considered the coldest town in Spain and has the milestone of having reached -28.2 degrees. In these types of places and situations, the resistance to -10ºC of the beacons is insufficient, so their connectivity may stop working, thus losing virtual visibility, or even fail to turn on. Another problem: snow. Beyond the problems caused by extreme temperatures, there is another phenomenon that in the winter season can interfere with the beacons. Much has been said about the visibility problems of these devices in broad daylight, in fog or on very tight curves, but snow can also become another obstacle. Beacons should be placed on the highest part of the vehicle where possible, usually the roof. If the snow settles, it can cover it and thus kill the physical visibility it provides us. The alternative. The V16 beacons aim to improve safety on the roads, warning other drivers of the obstacle posed by a car stopped on them. In the event that the beacon does not work due to problems with temperatures or snow, the option left is to contact the emergency services via mobile phone. The V16 beacons, which will be mandatory from January 1, 2026, are not without controversy. From the scams around them until accusations from groups of the Civil Guardthe DGT He had to admit his mistakes and has already explained that will be flexible with fines.

AI needs 650 billion a year to sustain itself. The problem is who will put them on the table

by

Those responsible for the JPMorgan banking entity they have done numbers. For AI companies to achieve a 10% return on their capital expenditure In 2030, they will need to collectively earn $650 billion. That’s like saying that the 1.4 billion iPhone users will pay $400 a year to use those models. It’s not impossible, but certainly it doesn’t seem simple. Many use it, few pay. Above all, because today the number of paying users is very small. According to the data from the consulting firm Menlo Venturestoday 1.8 billion people use AI around the world, but only 3% of them (54 million) are paying customers of some subscription. ChatGPT as an example. OpenAI esteem that in 2030 that percentage will rise to 8.5% for its user base, which they project will be 2.6 billion a week. That is to say: 220 million people will be subscribed to one of ChatGPT’s payment plans, which will probably have different prices than the current ones in 2030. They do not seem sufficient, at least a priori, to make the firm profitable as promised. Advertisements. It is more than likely that the advertisements they end up being the other great resource to earn revenue from AI models. Although Sam Altman indicated in the past that advertising would be “the last resort” to monetize, recent data reveal that those ads are about to be part of the user experience on ChatGPT. A very risky bet. JPMorgan’s estimate points to a future in which billions of people will pay a lot of money a year to use the best AI. Apple account with 1 billion subscribers to its services, Netflix with 300Spotify with about 280and Google account with 150 million subscribers on Google One alone. It is evident that there are many users willing to pay for services that are useful and entertaining. The question is whether AI will be for so many people. And AI companies, of course, are confident that they do. The non-surprise of the bubble. In The Economist indicate that a potential explosion of the AI bubble already it’s not going to surprise anyone. The curious thing is that there is no excessively notable concern for the consequences. In recent years the economy seems to have recovered surprisingly well from disasters such as the European energy crisis after the start of the Ukrainian War or the tariffs imposed by the US. Recessions, this economic newspaper points out, they are becoming rarer. Everyone has jumped on the bandwagon. Mass vulnerability exists, however. Stocks today represent 21% of Americans’ economic wealth —more than in the dotcom bubble—, and investment in AI companies is responsible for half of the increase in that wealth over the past year. And therein lies the danger. Recession in sight? People have earned more money and saved less: if the bubble bursts in a similar way to what it did with dotcoms, The Economist believes that net worth will fall by 8%. That in turn would cause a notable decrease in consumer spending. It is estimated that the US GDP would decline by 1.6%, enough to push the country into recession. The difference with dotcoms. In this case that global recession It might not be so deep for a clear reason: the root would be in the investment markets, and therefore it could be overcome with a little more room for maneuver. Central banks could cut interest rates to boost consumption, a good thing on that front but dangerous for vulnerable economies. The shock wave of the explosion. If the bubble bursts, what could also occur is a painful reconfiguration of global trade. Lower US demand would reduce its trade deficit, but would worsen the excess China production capacity. By not being able to sell (as much) to the US, it would flood other markets with its products, which would probably cause some protectionism in Europe and Asia. The world is preparing for the stock market crash, but not so much for the economic and geopolitical consequences that will follow.

Almost all phones with optical zoom have the same problem. This Chinese brand believes it has solved it in a curious way

by

The greatest illusion trick in mobile photography is continuity between cameras. When we zoom from 1x to 5x on a telephoto smartphone, we are not moving lenses like on a camera; the mobile jumps between fixed sensors and fills the gaps with digital cropping and AI. The result is those sudden jumps in color and image in the viewfinder and a loss of quality in the “intermediate zooms” that we make when pinching the screen. Tecno, the star brand of the giant Transsion—the fifth largest manufacturer in the world hot on Xiaomi’s heels in some markets—has taken advantage of its annual event to present two technologies that attack precisely this problem: a zoom that does not “jump” and a periscope that shrinks. Optical continuous zoom. And from an increase, up to nine. The most ambitious proposal is the “Freeform Continuum Telephoto”. On paper, it promises to maintain optical sharpness throughout. It represents an important leap, although it is not the first: Sony tried it with the Xperia 1 IValthough its range was more limited. LG also showed similar concepts a few years ago, but no one had promised to cover the main angle lens to the long telephoto lens in a single module. To achieve this milestone without turning the mobile phone into a brick, the Chinese firm moves away from the traditional design of lenses that move longitudinally. Instead, they turn to physical principle of the “Alvarez Lenses”: a system that employs two lenses with free-form surfaces that move perpendicular to the optical axis. By sliding one over the other from the side, they change the optical power of the set and achieve that zoom effect. This technology is related to recent reports that Samsung was developing cameras with continuous zoom for Chinese manufacturers. A periscope that folds on itself. The second innovation presented by Tecno attacks the volume. We are obsessed with increasingly larger sensorsbut the space inside the mobile is finite. Periscopic telephoto cameras require a lot of space, but Tecno and its “Dual-Mirror Reflect Telephoto” promise to reduce the size of the module by 50% and its height by 10%. Instead of a simple prism that bends light 90 degrees, the system uses coaxial optics that bounce light multiple times inside the lens using reflective mirrors. It is what allows long focal lengths in a shorter physical distance. However, this design has a physical trace– When using a central obstruction, the bokeh is not circular, but rather takes on a donut shape. Tecno sells it as an artistic feature, the truth is that it is a consequence of mirror optics. Battle against the accused. The new thing from Tecno comes at a time when mobile photography It depends a lot on the processing what are you looking for the photo instagrammable above realism. Going for better optics instead of digital cropping and AI rescaling seems to be the right direction to achieve naturalness. However, we must maintain some caution. The challenge of this zoom is not only that it works, but that it is bright. Maintaining a decent aperture throughout that range is no easy task. If the system is too dark, the ISO will shoot up, generating noise that the software will have to remedy: back to processing. For the moment, we must wait to see if these concepts end up in a commercial mobile phone.

There are 500 million users who could perfectly upgrade to Windows 11. The problem is that they don’t want to

by

If you are reading this and still using Windows 10you are at risk. Microsoft a month and a half ago ended the official support period for this operating system that was launched in 2015. The curious thing is that what should be happening is not happening. Dell as an example of what is happening in the world. Dell COO Jeff Clarke recently participated in an interview at The Motley Fool and they asked him for his vision on how the end of Windows 10 would affect the migration of users to Windows 11. That’s when he confessed that all his expectations came crashing down. The end of Windows 10 pointed to the growth of Windows 11. In fact, Clarke explained that before it happened he was very confident that this end of the cycle would lead people to buy a new PC or install Windows 11 on their computers. However, the executive indicated that they have realized that the adoption of Windows 11 is between 10 and 12 points below what happened with previous generations: people are not updating to this operating system as they expected. 500 million users simply skip updating. Clarke’s estimate is that there are about 1.5 billion devices (PCs and laptops) running Windows, and that’s where he made the most disturbing statement: “There are about 500 million PCs capable of running Windows 11 that have not been updated. And we have another 500 million that are four years old and cannot run Windows 11. All of them pose a huge opportunity to upgrade to Windows 11.” And yet, they don’t do it, or what is the same: A third of global Windows users do not have a PC officially compatible with Windows 11 and cannot directly upgrade Another third have a PC compatible with Windows 11 but users simply They have chosen not to do so. If it works, don’t touch it? For many users, including business users, the unwritten rule is often precisely “if it works, don’t touch it.” This is especially delicate in companies, because they may depend on legacy systems and if they update to new versions, conflicts may arise that affect the operations of the business itself. And still… A colossal security hole. Once again, what is really worrying about this is that although these PCs and laptops are working correctly, if they are based on Windows 10 or previous versions of Windows, they are absolutely exposed to all kinds of security flaws. At any time, these PCs could become victims of malware that turns them into members of a botnet, or of ransomware that prevents us from accessing our data unless we pay a ransom. This is already bad for individual users, but for companies the risk is enormous. A ray of hope. Here we just have to wait for users to realize that updating their equipment is important and relatively easy. In fact, on officially compatible devices this is basically a matter of clicking the “Next” button when running the update wizard. If your device is not compatible, there is a trick. On computers that theoretically do not meet the conditions—such as, for example, that do not have native support for TPN 2.0—there are not excessive problems either, because it is possible to “trick” Windows with a command or even with the use of a modified version of Windows 11. Come on, although it seems that you cannot update to Windows 11, the most normal thing is that in reality yes you can. And of course, there is Linux. If for some reason what users don’t want is to upgrade to Windows 11 because they don’t like it, the options are there in the form of Linux distributions. It seems that this path is being chosen by an already notable number of users, and this is demonstrated by the fact that, for example, Zorin OS—a fork of Ubuntu—has seen its distribution Zorin OS 18which arrived just at the time when Windows 10 was no longer officially supported, has been downloaded more than a million times in the last few days.

NASA needed to get to the Moon and had a problem with an insulating material. So it was put in the hands of the surfers

by

Now that we are immersed in the space race to reach Mars, it is worth looking back to see one of the most surprising anecdotes of the other race with which the United States achieved taking man to the Moon for the first time. And to achieve this they did not hesitate to use all available resources, from their best scientists to their best… surfers? Although it may seem like a joke, it took surfers to perfect the Saturn Vthe space rocket with which the Apollo missions took off between 1967 and 1973. The POT He had created a honeycomb-shaped insulator for his rocket, and needed specialists in the use of honeycomb-shaped materials… like that of the surfboards of the time. This story It was kept secret for years. But even though it ended up coming to light after a NASA engineer told it in an interview, it remains one of the most curious and unknown anecdotes of the space race. There are also references to it in documentaries such as one of the chapters of ‘Moon Machines’, available at YouTube. Surfers at NASA The second stage of the Saturn V, the S-II, was built by National American Aviation (NAA) in Seal Beach, California. It was composed almost exclusively of two tanks of oxygen and liquid hydrogen that, for logistical reasons, had to be placed almost close together and separated only by a thin layer of aluminum. But there was a problem, that the liquid hydrogen had to be kept at a temperature of about 20º above absolute zero, so They had to create a new insulator to cover your tank. They created one in the shape of a honeycomb, since the hexagonal design is the strongest and lightest in nature and we have been using it for thousands of years, but they could not get the insulating layer to stay stuck to the aluminum. Fortunately for the NAA their facilities were in one of the surfing capitals on the west coast, and their engineers realized that the surfers They also used honeycomb-shaped materials in their boards. They were therefore more experienced experts than any scientist when it came to dealing with these types of insulators, which is why they hired a few to design an effective way to apply it to the tanks. The surfers recommended applying the insulation with sprays with a foam that solidified forming hexagonal cells. The idea worked, the NAA finished the S-II, which was assembled with the rest of the parts of the Saturn V. The rocket took 24 astronauts to the Moon without any loss of useful shell, having only engine problems with Apollo 6 and Apollo 13.

Huawei has a patent with which to manufacture 2nm chips. The only problem is that it’s just a patent.

Huawei has just applied for a patent in which a new and unique process of advanced chip production. The patent focuses on improving one of the limitations of the technology of deep ultraviolet photolithography (UVP) to try to compete in this way with the extreme ultraviolet machines (UVE) to which China still unable to access. There are, however, many uncertainties here. The patent. Huawei formally submitted the technical documentation in June 2022 to the Chinese patent office, allowing the invention to be “protected” since then. The detailed content of their study was made public in January 2025, but It is now that it has come to light. The patent is only applied for, not granted or granted. The patent office is examining the application to determine if it meets the requirements. Why is it important. This patent tries to address the limitations of the so-called edge placement error (EPE, Edge Placement Error) in the advanced interconnection process used when manufacturing advanced chips. The method discovered makes it theoretically possible to use “metal spacings” smaller than 21 nm, even when using deep ultraviolet (UVP) technology instead of extreme ultraviolet (UVE), which is the most advanced photolithographic technology today… and to which Chinese manufacturers like Huawei do not have access. If it achieves its objective, the firm could have access, for example, to chips that would theoretically compete even with chips made with 2nm photolithography. Metal spacing? That term (metal pitch in English) refers to the minimum distance that exists between the metal lines that form the interconnections within the integrated circuit or, in this case, the chip. These lines carry power and data signals between the transistors, and that metal spacing is extraordinarily small for advanced nodes. The objective of the patent is precisely to allow the manufacture of these lines with a spacing of less than 21 nm. This gives rise to a possible process that could compete with the 2nm UVE photolithography used, for example, by TSMC. The important word there is “could.” Edge Placement Error (EPE). EPE is the error that occurs when a pattern on a chip is not placed exactly where it was intended by the chip design. The closer that metal spacing is, the smaller the EPE margin must be to prevent the lines from touching and causing a short circuit. At this scale it is incredibly complex to solve this problem, and Huawei’s patent precisely proposes a way to achieve it. Supervitaminizing “old” lithography. What makes this method possible is that UVP photolithography, less powerful and advanced than UVE, can be used to compete with it. This method would allow “jumping” the limits that this process now faces, and which normally had many difficulties in going beyond 21 nm. A double hard mask process of two materials and a special patterning scheme are introduced that theoretically allow us to go below 21 nm. and even 5 nm which are already very complicated to achieve with EUV. In short: China could achieve advanced chips without the need for use the most advanced ASML machinesto which you do not have access. But. Although the technique is apparently striking, there are two big problems here. The first and most important is that this is just a patent and that does not mean that the process can be transferred to reality. The difficulties in doing so are enormous, and that leads us to the second problem: the effectiveness of production would probably be very low and the yield (process success rate) would be greatly affected. That is to say: of all the chips theoretically produced with this technique, only a small part would be valid, which would waste a huge part of the investment.
