impossible

We thought that interstellar travelers were impossible to find current technology. Three have already been discovered

by

Less than a decade ago, the idea of ​​detecting an object of another solar system through our neighborhood was science fiction material. Astronomers were clear that they existed, but believed that our chances of detecting them They were practically null due to the limitations of current technology. In 2017, everything changed. First appeared 1i/ʻoumuamua. An object that baffled astronomers. Not only because it was the first interstellar object discovered in our solar system, but because its nature was and remains a mystery. With A strange formas elongated as a cigar or flat as an album, and a size of just 100 or 200 meters, it happened fleetingly leaving more questions than answers. Was it a comet, an asteroid or something completely new? The debate continues while moving away from us. Then 2i/Borisov was discovered. When we still wondered if we would see something similar in our lives, the answer came alone. In 2019, astronomers They detected a second object of another star system That was unequivocally a kite, somewhat larger than its predecessor (about 400-500 meters) and with a very different trajectory. Borisov confirmed that ‘Oumuamua had not been an anomaly. Interstellar visitors were real and we are able to find them. And to confirm it, 3I/Atlas arrives. On July 1, 2025, the Telescopes of the Atlas Network in Chile detected the third known interstellar object. After confirming your hyperbolic trajectory, He was officially baptized as 3i/Atlas. It is a real giant compared to the previous two, and marks a before and after in the study of these bodies. Like Borisov, it shows a clear comment activity, with a comma and a tail that lengthens as it approaches the sun. Therefore, it is a kite. But it is much bigger. Although the measurements are refining, initial estimates place their diameter between 5 and 20 kilometers. A colossal size that makes it much easier to study. A giant who will pass through Mars. 3i/Atlas is incredibly fast. It moves at an exhaust speed of about 58-60 km/s with respect to the Sun. much faster than ‘oumuamua (26 km/s) and Borisov (32 km/s). His career is also unique. It will reach its closest point to the Sun (its perihelium) on October 29, passing between the orbits of Mars and the Earth. Although at that time our planet will be on the other side of the sun, which will prevent its direct observation, it will be only 31.4 million kilometers from Mars on October 3. This opens a fascinating opportunity: that some of the probes that orbit the red planet, such as the Mars Reconnaissance Orbiter, can capture images of the interstellar traveler. Three important findings. Each of these objects is a time capsule from another solar system. All planets, asteroids and comets of our system share a common origin, but these visitors are authentic outsiders. They contain clues about the formation and composition of worlds that orbit other stars. Studying them is like receiving a geological sample from a corner of the galaxy that would take millennia to visit. Until now, we could only observe his fleeting step. But this is about to change. ESA is already preparing THE MISSION INTERPECTORwhose launch is scheduled for 2029. The idea is ingenious: the probe will not have a predefined objective, but will “park” at a point in Lagrange (L2) waiting for a pristine kite of a long period or, with some lucky, a new interstellar visitor to be within its reach. It would be the first rapid response mission to intercept one of these mysterious objects. In less than ten years we have not known if they existed to actively plan how to send a ship to touch them. With new generation observatories such as Vera Rubin, which is expected to find dozens of them in the next decade, we are entering a new era of astronomy. The universe sometimes brings us its secrets at home. Image | The interstellar comet 3i/Atlas (ESA) In Xataka | There is a single opportunity in 11,000 years of reaching the planet Sedna.

Uranium centrifuges have triggered war between Israel and Iran. Without them it is impossible to have the atomic bomb

by

Uranium centrifugers monopolize a good part of global attention since it began The last episode of the conflict between Israel and Iran on June 13. The government led by Benjamín Netanyahu has set as a fundamental objective dismantle the Iranian nuclear program that presumably seeks to develop the necessary technology to Manufacture atomic bombs. And to achieve it Israel and the US have bombarded The facilities in which Iran was carrying out the enrichment of uranium, such as the plants of Fordo, Isfahán and Natanz. According to Israel and the US, these Iranian nuclear facilities housed several hundred uranium centrifugers. It can even that several thousand of these machines. Its role in the nuclear program not only of Iran, but in that of any country with the ability to manufacture nuclear weapons, is to enrich 90%uranium. Otherwise it is not possible to use it to produce atomic fission pumps o Thermonuclear devices that combine fission and nuclear fusion. However, in these last pumps uranium is only used in the fission stage, which acts as a detonator of the nuclear fusion. In this last reaction two isotopes of hydrogen intervene: the deuterium and the tritium. Uranium-235 is the true protagonist of this story To precisely understand what is the purpose of uranium centrifuges it is necessary that we previously investigate in two isotopes of this chemical element Metallic, heavy and radioactive. Uranium is present in nature in very low concentrations, normally in rocks, land and water. Hence, its obtaining is expensive and its complex treatment, since it requires chemical processes capable of separating it from the other elements and impurities with which it usually lives. It has 92 protons and many other electrons orbiting around the nucleus, and the latter incorporates, in addition to the protons, between 142 and 146 neutrons. It is important that we remember that the nucleus of an atom is usually constituted by a certain number of protons and neutrons (although not always: the protio, the isotope of the most abundant hydrogen, has a single proton and no neutron in its nucleus), as well as by some electrons that orbit around it. The fact that the number of neutrons of the uranium nucleus may varyas we have just seen, it indicates that there are several isotopes of this chemical element, which are nothing other than atoms with the same number of protons and electrons, but different number of neutrons. In fission reactors and nuclear weapons it is used as uranium-235 fuel The reason why in the fission reactors and nuclear weapons is used as an uranium-235 fuel, and not another isotope of this element or any other chemical element, it consists that by bombarding its nucleus with a neutron (a process that is known as induced fission) the uranium-235 is transformed into uranium-236, which is a more unstable element. This simply means that Uranium-236 cannot remain long in its current state, so it is divided into two nuclei, one from Bario-144 and another of Crypton-89, and also emits two or three neutrons. And here comes the really interesting: the sum of the masses of the Bario-144 and Crypton-89 nuclei is slightly lower than the Uranium-236 nucleus from which they come (“disappears” around 0.1% of the original mass). Where has the mass we lack? Only one can be left: has been transformed into energy. Formula e = m c²probably the most popular in the history of physics, relates mass and energy, and what it says is simply that a certain amount of mass equals a specific amount of energy, even if the dough is at rest. In fact, the equivalence between mass and energy, proposed by Albert Einstein In 1905, he tells us something more important. The C of the formula represents the speed of light in a vacuum, which, as we all intuit, is a very large number (299,792,458 m/s). In addition, it is squared, which means that even a very, very small mass, such as the portion of the nucleus of an atom, although it is at rest contains a large amount of energy. This is what we know as resting energy. If the mass is in motion its total energy is greater than its resting energy. And, if we observe the equivalence between mass and energy, it is easy to realize that the mass of a body in motion too is greater than its resting massa phenomenon that It introduces us fully into relativistic physics. In any case, the energy we obtain by merging or fissting atomic nuclei comes from the force that keeps them together: Strong nuclear interaction. Understanding with some precision the relationship between mass and energy is important because it helps us understand how it is possible that a mass as small as that of an atom allows us to obtain such a large amount of energy. In any case, the nuclear fission process does not end here. And it is that each of the neutrons that we have obtained as a result of the disintegration of the Uranium-236 nucleus in the Bario-144 and Crypton-89 nuclei can interact with other physically nuclei, causing a chain reaction. However, not all neutrons emitted during the disintegration of the Uranium-236 nucleus will interact with a physirable nucleus. But they don’t need to do it all. It is enough that only one of those neutrons achieves it to obtain a stable number of fissures, and, therefore, a controlled reaction, which is the objective of the reactors of the nuclear power plants. Centrifugators serve to increase uranium-235 concentration The most abundant uranium isotope in nature is uranium-238. In fact, it represents approximately 99.3% of the total uranium. The problem is that this isotope is not physically. The uranium enrichment process seeks to increase the proportion of uranium-235, which, as we have seen, is physically, within the total mass of uranium. However, this last isotope is very scarce in nature. So much that only represents 0.7% of natural uranium. The nuclear reactors of the power plants require … Read more

Planting the heat of Córdoba in summer is impossible. I have tried a personal thermal dissipator to at least try

by

I do not discover anything to anyone if I say that In Córdoba it is hotter than on Charmander’s birthday. We have many good and beautiful things, such as the Mosque-Catedral, Medina Azahara or the Alcazar of the Christian Kings. This is the only city in the world with four assets of humanity, The first person to fly did in Córdoba And for having, we have even A traffic light with artificial intelligence. But if there is something we have and that we are left over, it is, without a doubt, heat. There are those who fight this excess of Celsius degrees leaving Fuengirola (also called Córdoba II). Others put in front of the fanunder the air conditioning or call the friend who has a pool at home with the excuse of “how long without seeing us.” I, for my part, have tried in a less conventional way. I have done it with a personal thermal dissipator of Sony: the Reon Pocket Pro. It is put below the shirt, but so you can see the size better and where it should be placed | Image: Xataka Terus dissipator … what? I know it sounds a bit strange (not as much as Go to the gym with an exoskeletonwhich also made), so we go in parts. The Sony Reon Pocket Pro is a portable thermal device that cools and heats the part of the body with which it comes into contact. That part is precisely the upper back area, just below the neck. It is not a portable air conditioning, much less. How does it work? The device incorporates two independent thermal modules in the rear that cool or heat according to the context (then we return to this) and a fan that extracts the heat from our body and expels it above. The two thermal plates alternate, so that when one reaches a certain temperature, the other is deactivated and activated so that the sensation of freshness is constant. These two plates work independently and cool or heat | Image: Xataka How do you get? We have to place it so that the two plates touch our body and the upper air exit protrudes slightly from the shirt. If we wear a shirt, we can use the adapter. The device is slightly curved, thus respecting our natural curve, and has a pair of flexible tubes that are placed around the neck and keep it subject. These, by the way, are not seen, but they stay under the shirt. And yes, they are noticed. The air exit should stay above the neck of the shirt | Image: Xataka These moorings should also be placed below the shirt | Image: Xataka Is it comfortable? Depends. It is acceptable if we take it while we walk or We are perfectly seated (With a straight back), and that weighs about 200 grams. If we change posture, for example, more reclined in the chair or lying on the couch, impossible. As for noise, I have not appreciated that the fan makes more account noise. I wear it right now and in my office, where only the noise of my mechanical keyboard is heard, I do not appreciate it in excess. However, I must say that it seems like a device too large and that finding the exact location in which it must be placed is complicated. It is not so “of remove and put” as perhaps you could expect a device like this, but you have to place it well, in its place, if we want it to work correctly. That it is more or less comfortable will depend, in large part, on the position we adopt | Image: Xataka Ok, but it cools? Let’s go to the point. The Reon Pocket Pro can be used in two ways: manual or automatic. If we establish it in manual, we can configure (via buttons or via app) the target temperature and the device will be in charge of reaching it. If we establish it in automatic, it will use, in addition to the data of the device itself, those of the Reon Pocket Tag to determine the objective temperature depending on the ambient temperature, the humidity and even the exposure to direct light. The problem is that this small sensor works well if it is abroad. If we carry it in the pocket (it is fully designed to hang it on the keys or in the pants), the data can vary. In any case, it works well and if we are going to use it in a room like an office for a while, just leave it on the table and forget about it. Reon pocket tag | Image: Xataka As for the sensation, it is … curious. As soon as we put it, we will notice how the surface of the neck begins to cool (or heat). It is almost instantaneous. With the passage of the latter, the sensation of freshness is improving and, thanks to the two thermal modules that are alternating, it is constant. And yes, cool. Now, the reality is that the one that is: the sensation of freshness, within that it relieves even going down the street, is very localized in the area near the location of the device. The cold mode sensation is the same as if you carry a bag of ice cubes on the back. In heat mode, it reminds me a lot of thermal blankets for neck pain. Image | Xataka On the battery. Using it at a medium cold temperature, the device lasts practically one day. A working day endures it without problem. At a lower or greater temperature, depending on the way we choose, less autonomy. In that sense, the use of hot mode spends more than cold mode, but for obvious reasons I have not used it just during these days. As for the load, it is completed in approximately three hours. So… Is it pleasant? It is, especially when you put it … Read more

A year ago Catalonia decided to start regulating her rentals. Now it has something that seemed impossible: lower prices

by

In a context marked by the Price climbingrecord rents and a real estate market that Start nonsense With the costs prior to the 2008 brick crisis, Catalonia wanted to break yesterday with the bullish rhetoric. Their rentals are going down. And quite clear in addition. In the region as a whole, the leases cost today, on average, 4.7% less that a year ago, a decrease that reaches 8.9% If we talk about Barcelona. With that data, the Generalitat wants to breastfeed by the First year of price regulation in the 140 tension municipalities in which the Housing Law applies. What happened? That the Generalitat of Catalonia has just done something unusual in real estate information in recent years: to use a negative sign to talk about prices. According to The data broken down By the Minister of Territory and Housing, Sílvia Paneque, the average lease It has been cheaper In the region as a whole and, in a special way, in those municipalities in which the price regulation was applied a year ago under the protection of the state law Housing How much has it dropped? The information handled by paneque is based mainly on the Bail deposits And it shows the “photo” of the Catalan real estate market throughout the first quarter of the year, which allows analyzing how prices have evolved between the beginning of 2024 and 2025. Its first conclusion is that the whole of Catalonia the middle rent has experienced a year -on -year fall of 4.7%. If we look concretely in the 140 municipalities that declared tension markets in March 2024 And in which, therefore, prices were allowed to regulate in certain cases, the descent is somewhat more pronounced: reaches 4.9%. The big surprise leaves her specifically Barcelona. There the average cost of rentals has collapsed several more points, to mark an annual fall of the 8.9%. And how do contracts evolve? That is the second surprise that has left paneque. The counselor ensures that this price drop has not arrived accompanied by a contraction of the Catalan rental market. Moreover, according to your data in the first quarter of 2025, the number of lease contracts in force in the region has increased by 3,112. “It continues to grow, which tells us that the rental park increases,” defended The leader. He release Shared by the Generalitat does not allow, yes, to assess whether the rhythm of the new leases has risen or down the last year. What the counselor clarifies is that “a large part” of the contracts that were already in force have lengthened. Or what is the same, moves are reduced. The country Precise that in the tensioning municipalities the new contracts have decreased by 22%. How do you interpret the data? “We believe that the clarification in the contracts has helped to have these good data that allow us to say that there are 11,807 more homes for rent than a year ago,” celebrate The head of Housing, who points out that the majority (7,865 contracts) are concentrated in the 140 municipalities declared tension in 2024. In the Barcelona case, during the first quarter of 2025 the total number of rental homes has increased by 423. “There are 1,202 more households for rent than a year”, Apostille The Generalitat. Why is it important? Because beyond the implications it has for the Catalan real estate market and, specifically, the landlords and tenants of the region, the data presented by Paneque shows the practical effects of the regulation of rentals and the application of the housing law released to In March of 2024. Generalitat herself wanted to emphasize a message whose interest transcends its borders. After all, Catalonia was The only community that applied the law. “The data are good and show us that containment and legislative and regulatory measures help to guarantee the right to housing on this road until reaching a public park of 15%,” insisted The counselor of the branch. Are the first data known? No. Paneque is not the first to slide that idea. In Marchwhen an exact year of the application of the rental price index in 140 municipalities of Catalonia, Minister Isabel Rodríguez already claimed that the data in the region showed that “the Housing Law works”. By then the fall of the amount of leases in Catalonia it was 3.3%. In the city, the decrease reached 6.4%. Is it all positive? No. On Tuesday, Generalitat himself shared data that show a seasonal rental boom, a formula that is normally agreed for periods below the year and It allows to dodge The norm. If in 2019 it represented just 2.1% Of the rental floors announced in Barcelona, ​​in 2023 it already meant 14.4%. And the information revealed yesterday by Paneque suggests that they have gained weight in the community real estate market. The data handled by the Generalitat shows that 2,242 contracts Temporary of the first quarter of 2024 has passed, during the same period of 2025, to 3,415. In other words: the formula has experienced has increased considerable, from 52%, in just one year, gaining weight among the new contracts. During the first three months of last year, 6.1% of the new agreements signed in Catalonia were adjusted to that temporary modality. At the start of 2025 they already represented 11%. Aware of that accelerated boom, the Generalitat It has been proposed Limit prices in those seasonal rentals that have residential use, a decision that the Generalitat creates more justified than ever. And the rest of the contracts? The counselor He celebrated yesterday That the new regulatory framework and price regulation offer more stability to tenants by now having the great less incentive to get their homes to the rental market. “We are seeing that a large part of the contracts in force are extending their duration, which translates into the reduction of extinguished and, therefore, in greater stabilization,” Highlight. His statement is however some nuances. Shortly after the new regulation in the 140 Catalan municipalities … Read more

The house is getting so impossible in Madrid that people are returning to an unexpected place: seseña

by

Real estate markets have their own symbols. For years Seseña was from Lick, The real estate bubble which exploded in 2008. Today is something very different: the housing crisis which faces Madrid (and Spain), which has allowed that ancient ghost city associated with Francisco Hernando‘El Pozero’, being reborn strongly. With prices in climbing And a serious housing deficit In the capital, more and more people look out of Madrid when they have to look for a house, to localities such as ValladolidSegovia … or seseña, where It has resumed construction and arise New promotions residential AND It is not the only “Ghost city” that is gaining impulse thanks to the families expelled from Madrid for a market that increasingly tightens Your pockets. Of brick bubble icon … For years Seseña, especially THE PAU THE QUIÑÓN (The city projected by ‘Paco el Pocero’) was an icon of the years of brick excess and The real estate bubble. Also of his hangover. Those who bought in the middle of the urban maelstrom found a kind of “Ghost Barrio”homes in the hands of banks and a fractured market in which prices did not stop falling. If in 2007 a two bedroom floor cost almost 200,000 euros, seven years later, with the banks desperate to get rid of the properties, it could be bought by less than half: about 60,000 euros. … to enjoy a golden age. Today things are different in Seseña. After years with half -building works and worried For the Okupas, the town is living a new golden age. Families arrive. They open business and services. Projects such as PARQUIJOTE. And they raise New promotions. In 2023 The newspaper He spoke of two major projects: an urbanization of 156 houses that moved between 110,500 and just over 200,000 euros and another of chalets. The change has been cooking for some time. Almost a decade ago The countryHe dedicated him A wide report in which he explained how the residential city the Quiñón was gaining impulse little by little, with families, businesses and services. At that time the newspaper spoke of 6,411 inhabitants. Last year Antena3 again analyzed the situation of the Macro Urbanization Toledana and He found An increase in the number of residents, in addition to a growing demand for housing. “Three years ago you could find a house easily here. Now it is almost impossible,” explained At that time Vanesa, a woman who had installed time before in the Toledo urbanization after buying a four -room house with storage room, garage and pool for about 150,000 euros. Waiting list to buy. The last clue on the rebirth of the urbanization of Seseña gave it A few days ago Reuters, who has found The growing interest by the town. Although it is about 40 kilometers south of the capital and does not have the best connections and public transport, more and more families seem interested in settling in their apartments. Reuters speak With an agency that had a waiting list of 70 people for each home. Seseña (and something else). The area has also seen how the new work was also activated. Promotora Impact Homes, for example, is promoting a promotion of 156 homes which started in 2023. Its goal is to have it ready throughout this year. In the sector there is even talk of presale levels of almost 50% In new buildings. “Seseña is 100%,” celebrates the mayor, Jaime de Hita. His is not the only town in Madrid that has seen how his brick was activated. Something similar It has happened in Valdeluzurbanization located 75 km from Madrid that It was halfway after the outbreak of the real estate bubble. Its mayor wait that the population triggers over the next few years. Reuters appointment even a third example: an urbanization located on the outskirts of Bernuy de Porrerosapproximately 100 kilometers north of Madrid, which has also recovered the activity after remaining almost abandoned. And what is the reason? All these populations have something in common: their relative proximity to Madrid, which makes them an attractive destination for families that end up being expelled from the capital for the high cost of their home. Is The case For example, from Nestor, an employee of the construction sector who four years ago left Carabanchel to move with his family to Seseña. Living in Seseña requires you to get up every day at dawn and take the 6.30 h bus that takes it to the capital, but the price gap makes that discomfort more than assumable. In his day Nestor moved to Seseña because the rentals were there 20% lower than those of Madrid, Explainand a few months ago he decided to take another step and become an owner: together with his wife, he bought an apartment in the Toledo town for 240,000 euros. “We chose this close site because we can pay it. Madrid is very expensive right now,” The man tells. Is it a unique case? No. It comes rapidly to the newspaper library to meet Testimonies of families who have decided to settle in Seseña or professionals in the sector who attend the rebirth of urbanization and its buildings. “They seemed monsters that were going to stand for the future, but the need for housing has caused them to reactivate,” confesses A real estate to Tele5. “We move in prices below 200,000 euros. That is impossible in Madrid.” Money issue (and km). Seseña is not the only town to which the families expelled by the Madrid real estate marketthat only in the last year has seen how housing became more expensive, According to idealist. The improvement (and cheaper) of communications, especially the train, has caused Segovia or even Valladolid being hosting people who work for companies in the capital. In those municipalities they find homes at prices that, such as I recently recognized A family installed in Valladolid, “Nor would they smell” in Madrid.

We can see everything but it is impossible to find it

by

We have the general feeling that on the platforms of streaming We can find everything. But you have to find it. The prioritization of the quantity on the quality that the streaming He carried out for years to build catalogs is now throwing unpleasant results for the spectators, even when the main platforms have talked about Revert the situation. We are facing an overcually, full of content panorama, but at the same time, confusing and unmanageable. Quality exists, but locating it is not so simple. Deep transformation. After years of expansion and an unbridled career for accumulating the largest amount of possible titles and productions, the main platforms began in 2023 to rethink their strategy: The amount is no longer alland the sustainability of the model is to prioritize the quality of the contents. This Production decrease of original Not only has it brought a rhythm of less frantic premieres. It has also given rise to a stage of cuts, cancellations and unpopular decisions, such as stop shared accounts either introduce advertising. And above all, to some confusion: now we have so much material at our disposal that it is impossible to find it. To the search. In recent years, users have become accustomed to a constant and inexhaustible flow of new content. For years, the strategy of flooding the market with continuous premieres became the norm, generating a almost addictive expectation. There was always something new to do. When that trend has stopped, we have landed in the opposite situation: as counted This Salon article in which they defended the thesis that although there is more material to see in streaming than ever, the complicated thing is to find it. Can’t get no satisfaction. Now that content is released at lower speed, The public can interpret it as a fall in quality and interest. In addition, the Culture of binge-watching He is already completely settled, and only remakes this feeling. But above all: streaming platforms are more confusing than everwith the algorithm sliding for each slide, for each category, sometimes not even knowing what it wants to see, the viewer finds it easily. Have you ever seen stuck in an Apple TV+ program without knowing how to return to the main menu? Have you ever reset the platform after an ad? The bugs multiply, the categories are a maze, the search is an absolute odyssey. As there is not enough new programming to appease the needs that the platforms themselves have generated, These become irresoluble riddles so that it seems that the content has buried us. The wandering is over. Therefore, various studies detect A trend. Although the public spends a lot of time wandering through the platforms in search of something to see, we are trying to cushion those hours Returning to “Analog” recommendation systemsthat dodge so much the undisputed Fall in the clarity and usability of the platforms Like the presence of algorithms more and more poor. Platforms such as letterboxd and a certain revaluation of “human recommenders” They acquire a renewed impulse in the post-social era (Newsletters, for example), and are the best proof of the fall of the dictatorship of the algorithm. Forgettian parenthesis. Salon highlighted in his article another phenomenon of less accelerated times than these. Before they mediated very clear parentheses between The different exhibition windows of the films: a premiere in cinema took a year to reach exploitation in domestic physical formats; From there he could spend another year or more before we saw him on television, first in payment channels and then already on open television. And that was the end of the road: it was considered that the film had made its commercial tour. Now it’s all more accelerated and confusing: A movie can take just a few months to move from cinema to streamingwhile goes out for rent and digital sale, skipping the physical format. This chaotic race makes a film that, in our head was newly released or even in the cinema (Salon gave the example of ‘The Phoenician plot’ of Wes Anderson), it can actually be seen in streaming. It is only one more detail that adds to the generalized confusion: we have everything within reach of the hand, we often escape due to lack of information. Or because we simply do not supply. Solutions in sight. The ways to follow are complicated, especially at times like the current one, when Netflix has distanced themselves from their competitors and these are unable to follow their rhythm and their financial muscle, and cross recovery phases of an identity that goes beyond being “Netflix competitors.” That is, we are in a moment of transition in the industry that only adds confusion and lack of definition to all these problems. What can the platforms do to better define their services, so that this feeling disappears in the spectator of “is all there, but I have no idea how to find it or what I want to see”? We return to the initial problem. The platforms have to solve the great drama that we spend hours looking to see: according to A December 2024 studyAmerican spectators spend 110 hours a year trying to decide. It is too much time, especially considering that the problem has not changed: before, there was too much to do. Now, it is impossible to know what they have released, where it is or how to access it.

The Soc Xring O1 is an “impossible” prodigy. This is how Xiaomi has dodged the demanding US restrictions

by

Xiaomi’s Soc Xring O1 is making a thunderous noise. His debut at the 15S Pro smartphone, the PAD 7 Ultra tablet and the Watch 4S clock is being preceded by performance figures that They place it ahead of the Snapdragon 8 elite of Qualcomm and Dimensity 9400 of Mediatek. He is not but that we are bad if we are in mind that he is the first flagship designed by Shanghai Xuanjie Technologies, the Xiaomi subsidiary specialized in the design of semiconductors. However, in this article we will not investigate the performance of this chip or compare it with the alternatives proposed by Apple, Qualcomm or MediaTek. What I propose is that we verify how Xiaomi has achieved that the US Industrial and Security Office allows you to manufacture it in N3E (3 Nm) node of TSMC. This Chinese company is not included in the “blacklist” of the US, but this is only part of a story in which Xiaomi has proven to have a huge expertise. TSMC lithography has a leading role in the performance of this chip During the presentation of the soc Xring O1, Xiaomi revealed some details Very interesting about its architecture, and there is no doubt that ‘Xuanjie’ engineers have done a very good job in this area. However, Lei Jun, the founder and general director of this company, He recognized yesterday During the event that its purpose from the beginning was to put to tune a soc produced in the most advanced lithographic node available. And it is that a well -executed architecture and an avant -garde integration technology are the two ingredients that must necessarily intervene in the recipe of a flagship. As I mentioned a few lines above, Xiaomi is not included in the “blacklist” of the US, but this condition is not enough to access the N3E node of TSMC, which is One of the most advanced in operation currently. This last company is from Taiwan, but both the machines of The Dutch company Asml which uses to manufacture its integrated circuits such as wafering processing techniques that they use incorporate American technologies. This is the circumstance that empowers the US when intervening in the ASML and TSMC business. The US government decides who has access to its technologies even if they reside outside its borders In this context, the US Industrial and Security Office of the US Commerce is responsible for controlling the export of US technologies that can be used for military purposes, and therefore, they have the ability to compromise national security and condition US foreign policy. All this means, in short, that the US government decides who has access to its technologies even if they reside outside their borders. Xiaomi’s Soc Xring O1 is on the role as advanced as the best SOCs for smartphones that have Apple, Qualcomm or MediaTek and can be used for a very wide range of applications that go beyond their integration into a mobile phone or a tablet. In The current tension situation They hold the US and China it is surprising that TSMC has been able to manufacture this chip for xiaomi In one of its most advanced lithographic nodes. The interesting thing is that he could because the engineers of ‘Xuanjie’ have calibrated the design of their soc in such an ingenious way that they have managed to throw a very competitive performance without breaching the regulation of the US. In this delicate balance lies the authentic merit of Xiaomi. In TSMC practice it has been able to manufacture it in its N3E node because the socket Xring O1 meets three fundamental conditions. The first of these is that it has been produced in Taiwan and not in any of the countries of Group D: 5, which are the nations to which the US considers a threat, such as Iran, North Korea, Syria, Myanmar, Venezuela, China or Russia. In addition, this SOC incorporates 19,000 million transistors, so it is below the threshold of 30,000 million transistors. If I had exceeded this TSMC limit, I could not have manufactured it for a Chinese company. The interesting thing in this area is that the engineers of ‘Xuanjie’ have managed to set up an architecture capable of delivering very competitive performance and efficiency using a relatively moderate number of transistors. The third and last condition that this Xiaomi chip meets is that it does not live with HBM memories (High Bandwidth Memory), which are the ones that work side by side with the GPUs for artificial intelligence (AI). We only have to have the opportunity to try it thoroughly in one of the Xiaomi devices that are going to bet on it to check if it is really up to the expectations it has generated.

If the question is when the next blackout will occur, the answer is simple: it is impossible to know

by

He Bru what last April 28 It has generated many questions, and among them a couple stand out that seem inevitable: the first, if there are possibilities that it will produce again Another massive blackout. The second, if any, when will it happen? It is impossible to answer these questions with total certainty, although there are ways to reduce those possibilities to the minimum possible. Impossible to respond to that. To Niehls Bohr, the father of quantum physics, the phrase “making predictions is very difficult, especially when it comes to the future” is attributed. That also happens when trying to predict A nearby potentialsomething practically impossible and what also contribute several arguments. We still do not know the origin of the blackout. One of the problems of trying to answer that question is that we have no definitive or officers about what caused the blackout. From the Spanish Electric Electricity (REE) it was stated that the blackout It was due to a generation disconnectionbut they still do not give details about the specific causes that caused such disconnection. The experts They point to renewables As a possible cause, but at the moment nothing is confirmed. And without knowing the origin of the problem, we cannot know how to avoid it in the future. An unfortunate prediction. Pedro Sánchez, a jacket but without a tie, appears at a press conference. At a given time he says that “there will be no electricity blackouts.” The videowhich has now gone viral, it is not these days, but of September 6, 2022. At that time those words were pronounced in the context of a possible Russian gas cut throughout Europe. But there has been, and the question is whether there will be. The president of the Government was wrong in his prediction. Two and a half years later Spain has suffered The biggest blackout in its historyand one of the great questions that citizens have been asked is when the next blackout will occur, If it occurs. Never say ever. The research of the causes will lead to means for something like that not to happen again. The President of the Government spoke In your appearance of April 29 that there would be reforms so that “never” a generalized electric blackout is repeated like that of April 28, but even with all these reforms and measures zero probability does not exist. There are impodeables. Even in the case of detecting and correcting the problem caused by the blackout, it is still impossible to ensure that another will occur in the future. There are of course possibilities that a technical, human error or a natural catastrophe poses blackouts at some point. Spain has improvement margin. As we have commented In Xatakathe Spanish energy mix needs a stabilization system of the robust network, but also the Iberian Peninsula is an “Energy Island With very little international connection. Thus, we need an integration stronger With the rest of Europe to balance demand, strengthen system safety and share surpluses. There are other possible measures that can be taken, and as explained by the analyst Javier Blas In Bloomberg“The design of the network, policies and risk analysis are not yet up to the management of excess renewables.” All this is important when minimizing the risks of another future blackout.

Elon Musk’s ambitions were impossible to comply

by

Tesla has presented results. And they have been so bad in this first quarter of 2025 that it would be necessary to travel four years ago to find similar figures. There are various reasons but Elon Musk’s ambitions and promises are having their direct consequences on the company. An entire life. Four years for Tesla is a whole life. The company has been growing at a devilish pace until last year. But 2024 already closed it with sales lower than the previous year despite do everything possible to avoid it. In the first quarter of 2025, the benefits have fallen to just over 400 million euros, 71% less that in the same period a year ago. You have to go back to 2021 to find such a low figure. The problem for the company is that, then, it sold one less car (the Cybertruck was just a promise) and still did not reach one million units sold. That is, going back four years for Tesla is to go back a long time because the company was very different. A 2025 to shake. The first three months of the company have been really bad. To the point that They would have lost money If not for the Sale of regulatory credits (The payment made by other companies to meet in the average emissions by submitting to the regulators under the same group). In the absence of knowing to what the update of Tesla Model and is directly affecting its sales, the truth is that the company is leaving huge falls in countries like Germany or Francethe ones that sell the most electric cars in Europe. In the German country, in fact, they reach 60% fall. At the same time, their actions have collapsed and right now they cost half that in December 2024. This future of the actions must be taken prudence since they are intimately linked to the figure of Elon Musk. In fact, despite the bad results, the confirmation of the company’s CEO to abandon part of its governmental tasks to focus on Tesla has raised its price by more than 10%. Musk. Will reduce your work in the United States government “significantly”. This has been the word used by Elon Musk to quantify the amount of hours he will stop using in front of Doge (the department that leads within the State) to dedicate it to Tesla. This task has been, for some investors, the reason why the company has shipwrecked in recent months. For others, such as The New York Timesit is evident that there is damage to the company’s image with the statements and gestures of Elon Musk. The anger of those who have promoted BYcots to the Company They have focused, above all, to highlight the attitude of their greatest shareholder. A low profile in the government can be understood as a longer time dedicated to Tesla or as a lower public exposure and, therefore, a less worn image. The first interested, in fact, It is Musk itself whose fortune depends largely on the future of Tesla. But not everything is political. It seems unquestionable that Tesla’s image is irremediably associated with the figure of Elon Musk. He Financial Times He came to qualify the owner of the company as “demolition ball.” But there are other edges that deserves to stand before accusing Musk’s political drift as the only guilty of the bad results. The model hangover and. Something that explains the low sales of Tesla is that Tesla Model and has been renewed in the first weeks of 2025. Several factors must be taken into account: The lines have had to be renewed, so production has been reduced. Until in a few months we will not know how many possible buyers were waiting for the update before formalizing the purchase. To sell the Tesla Model and in stock, great discounts and very attractive financing have been applied, greatly reducing the profit margin. In the coming months we will begin to see how much the update of Tesla Model is interested and in front of the competition. In 2024, Tesla sold 1.77 million cars in the sum of the Tesla Model 3 and Model Y. of them, 1.09 million were represented by the electric SUV despite the fact that it was already known that the car was going to be renewed. Any mishap that hurts Tesla Model sales and is, right now, a problem for the company since half of sales are from this car. A cybertruck that is failing. Another of Tesla’s great problems and, probably, its greatest commercial failure. He Tesla Cybertruck He promised to be a supervent. The volume of reservations I encouraged to think about the car in these terms. But After the first feversales have collapsed to the point that analysts talk about the company will only produce 55,000 units a yearcompared to 250,000 promised units. Tesla had the opportunity to Make your cybertruck an aspirational vehicleof low production and great benefit that will report benefits in brand image. However, he has starred Memes on social networks And above all, Review calls have been continuous for all kinds of reasons, damaging its value. To the point that the company already seeks a solution to place thousands of them in markets outside the United States. The car that never comes. At the same time, Tesla and Musk have been promising for years An electric car of $ 25,000. One that has been impossible for the company to sell. If we do not have an electric car of $ 25,000, it is simply because the company has not found a way to make it profitable. In recent months we have known that the alternative will be a kind of Tesla Model and in miniature. But the car should arrive as a more affordable option than the current SUV as it would touch $ 40,000, according to The Wall Street Journal. In the same terms it was expressed Reuters Recently and in … Read more

It seemed an impossible enemy, it was actually the brightest antipyretary system in a video game

by

Piracy and entertainment are two concepts that They go hand in. In video games, this has meant a kind of race between the cat and the mouse, with the video game companies pulling inventiveness to try to pay players paying for their products. At the moment, Denuo is a very safe tool – that not invulnerable -, but throughout history we have seen most imaginative antipyertería systems. And the most memorable case is that of ‘Serious Sam 3‘. The reason? A giant and implacable scorpion that was looking for you to end with you if it detected that your game was a pirate. And the players accepted the challenge. Aid! It ran 2011 when the Croatian Croteam team (their heads did not break a lot) launched the third installment of its hilarious shooting saga ‘Serious Sam’. At that time, the antipyertorous measures were so rudimentary that the game came out ‘cracking’ within a few hours of the official launch, so many users quickly made a copy. Except in some cases in which mouth to mouth causes peaks of players months or years after the launch of a title, it is usual for forums and social networks to fill out of comments on a newly released game. As a minority, there will always be players commenting on the levels, which seems to them the game and reporting problems. And shortly after the launch of ‘Serious Sam 3’, the players began to complain about something: a Red scorpion that appeared in his departure and prevented them from continuing with the game. Even recently They published Some complaints in Steam. Scorpion. These players described the scorpion as a huge, invincible, very fast entity, that shot incessantly, that it was a sponge of bullets and that did not leave you alone at any time and complained about what they believed was a bug or a programming failure in the game code. The enemy’s pint is quite terrifying, which added to his fire power and the fact that it is invincible … well, it was not a pleasant drink. The little girl is that it was not a bug, but a characteristic of the game. Croteam knew that it was impossible to put doors to the field and that his game was going to be pirated, so he scheduled the game with a special characteristic: if he detected that the copy was a pirate, the invincible scorpion appeared and it was not going to stop until he killed the player. It was impossible for the player to enjoy the game in those conditions. Praise. In the video we left for some paragraphs, we can see an example of how the community took this movement. “Simply, I adore Croteam. They are not the details that the study has added to the game. No, no, no. It is the introduction of an arachnid, immortal and very fast enemy that is part of its antipirable system. And it is the icing on the cake.” That was the description of the shared video just a month after the launch of the title, but in the comments we can see dozens of players who reacted in similar ways. Comments such as “It is the best antipirable system in history”, “The movement of the bug terrifies me”, “Do not annoy, have applied antipiría measures either for once. This is comedy in its purest form” or “This is how the DRM should be. It has no negative effects for legitimate players, but hilarious consequences for pirates” show that the system was not badly received, at all. And, among all praises, only a few commented things like “expect, that pirates have extra difficulty? That is not fair.” And there were those who accepted the challenge. And the ‘Commission’ arrived. Thekotti He is a player who has been going up for years Speedruns to your YouTube channel. It has some absolutely demential and a few years ago raised a video passing in just over half an hour ‘Serious Sam 3’. A time later, he assumed the challenge of Croteam and went up A new Speedrun of the game, this time with a brand of one hour and 14 minutes until the game is completed. Why 45 more minutes if he was already an experienced player? Because he played the version with…. Scorpion. The bug took little to appear, but Thekotti was so fast that the scorpion had to reappear in front of him every two by three. With what has been learned, he tried again, lowering his brand until the time and six minutes. Seeing the video is a show, especially because that terrifying measure is nothing: Mods to activate it in legal copies. Obviously, this is not how most players enjoy the game, but it must be said that this movement by the Croatian study liked it so much that it inspired the Creation of Mods so that players with legitimate copies of the game could introduce the relentless scorpion in their games. I have to comment that I was never interested in the saga, but when I learned about the existence of this, I downloaded the pirate game, I laughed for a while, I checked that the bug was superman and bought the game in the first Steam sales in which it was available. In this case, I can say without fear of being wrong that it is one of the best ideas to discourage piracy, unless a PROPLAYER He gets in his head play your game without care of these measures.
