problem

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.

by

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.

We have a problem with cardboard recycling. In the United Kingdom they believe that the solution is to use it in a power plant

by

Every day, millions of cardboard boxes leave our homes heading to the blue container. They are the last link in an accelerated consumption cycle in online commerce. However, this material, so everyday that we don’t even look at it twice, could be on the verge of an unexpected second life: becoming fuel to generate electricity on a large scale. A residue that enters the energy map. A team of engineers from Nottingham University has shown for the first time that used cardboard can be used as an effective source of biomass in power plants. The investigation, published in the journal Biomass and Bioenergycompares cardboard with a common reference for industrial biomass: eucalyptus. The engineers didn’t just watch the cardboard burn. They crushed it, studied its shape, broke down its chemistry and analyzed how it reacted to heat and what type of carbon it left behind. They even developed their own method—based on thermogravimetric analysis—to measure exactly how much calcium carbonate each sample contains. This component, common in printed cardboard, gives rigidity to the material but also conditions its behavior when burning. Thanks to this procedure, they can predict which type of cardboard will work well in an industrial boiler and which could cause problems. The science behind cardboard that burns “better.” The study did not stop at theories. He tested the combustion of cardboard in two types of systems equivalent to those used in power plants: Drop Tube Furnace: Simulates the rapid combustion of pulverized biomass.Here, the researchers observed that cardboard particles develop chars (the carbonaceous remains that remain after the first combustion phase) highly reactive, with a predominance of fine and porous structures that favor a burnout accelerated. Muffle Furnace: Simulates fluidized bed or grate systems. Even with longer residence times, the paperboard maintained its excellent combustion profile. In addition, the size and shape of the particles were characterized through an analysis with more than one million particles per sample; The tendency of cardboard to form “spongy aggregates” during grinding was observed—a challenge for its industrial handling—and characteristics such as sphericity and aspect ratio were correlated, something that could improve future combustion models. As the academic study explains, this detailed analysis allows predicting combustion efficiency and designing industrial strategies to integrate cardboard into the fuel flow. The result was very favorable. Thanks to this experiment, the engineers managed to demonstrate that cardboard has less carbon (38%) than eucalyptus (46.7%) and its calorific value is also lower (15.9–16.5 MJ/kg versus 21 MJ/kg). However, its chars are finer, porous and reactive, which accelerates combustion; In addition, it contains much more ash (8.9–10.6%, compared to 0.6% for eucalyptus), a critical aspect for boilers. What remains to be resolved? Although the technical potential is evident, the study makes it clear that cardboard is not ready to enter the boilers of a power plant tomorrow. There are three fundamental challenges that must be addressed: Management and processing problems. When ground, cardboard does not behave like wood: it forms spongy lumps of very low density that make internal transport difficult, complicate the continuous feeding of boilers and can increase the risk of blockages and accumulations. The study warns that it will be essential to adapt the grinding and feeding systems to guarantee a stable and safe flow. The behavior of calcium. Cardboard contains very high levels of CaCO₃, especially when printed. This calcium can behave in different ways depending on the temperature and type of boiler. In certain cases it raises the fusion temperature of the ashes – which is positive -; In others it can favor the formation of slag or alter the quality of the fuel. The study recommends analyzing the behavior of cardboard according to the type of plant, because not all technologies tolerate these variations in the same way. Large-scale industrial validation. Laboratory tests are promising, but the decisive step is missing: testing the cardboard in real operating conditions. According to the researchers, the industry will have to carry out tests on different technologies in boilers, evaluate emissions, study the accumulation and composition of ash and check their compatibility with existing biomass mixtures. Only then can it be determined whether the cardboard can be safely and stably integrated into the mix of biomass. An everyday material with an unexpected future. Cardboard protects pizzas, televisions, books and appliances. We recycle it without thinking too much about it. But this research from Nottingham suggests that this everyday waste could become another piece of the energy transition, helping to diversify fuels and take advantage of an abundant and local resource. Today we see it as garbage. Tomorrow it could help produce electricity. The spark has already been lit: now we need to know if the industry wants – and can – convert it into real energy.

A Chinese startup claims to have created its own TPU to compete with NVIDIA. The only problem is that it is three years late

by

A Chinese startup called Zhonghao Xinying (known internationally as CL Tech) has come to the fore with a bold promise. The company claims to have developed an AI chip that not only circumvents Western intellectual property restrictions, but also outperforms NVIDIA’s A100 chip. Which is very good, but also a little bad. Chana arrives. The chip in question has been named “Chana”, and according to SCMP we are dealing with a GPTPU (General Purpose Tensor Processing Unit). Unlike NVIDIA GPUs, aimed at accelerating AI workloads, this is an ASIC, that is, an application-specific integrated circuit designed from the ground up for neural network workloads. promise. According to Zhonghao Xinying Chana, it offers up to 1.5 times the performance of the NVIDIA A100 based on the Ampere architecture. Not only that: it achieves that performance with 30% lower consumption. The startup highlights that the computational cost per unit would therefore be less than half of that offered by the A100 chips. A little history of the company. Behind Zhonghao Xinying is Yanggong Yifan, an engineer formed at Stanford and the University of Michigan. He worked on the development of several generations of Google TPUs and also on the development of Oracle chips, and in 2018 founded this startup in Hangzhou together with Hanxun Zhengan engineer who worked at Samsung for several years. They were joined by other engineers from Microsoft, Oracle, NVIDIA, Amazon and Facebook, they indicate. on Baidu. We are therefore faced with several of those cases of “boomerang talent” with Chinese engineers who are forged in the US and then return to China to create solutions for their own industry. Solutions that do not depend on the West. Yanggong affirms that its chip features “fully self-controlled IP cores, a custom instruction set, and a fully in-house computing platform. Our chips do not rely on foreign technology licenses, ensuring long-term security and sustainability from an architectural perspective.” But. Although the achievement is striking, it is necessary to put it in perspective. The NVIDIA A100 is a 2020 AI GPU, and even with the improvements that this Chinese startup promises, its performance is, for example, far from H100 chips with Hopper architecture that appeared in 2022. Not to mention of the latest Blackwell Ultra chipswhich are currently NVIDIA’s greatest exponent in terms of AI chips. There are also no details about who makes the chip, and one of the candidates it would be SMICwhich has 7nm technology. They are very far away, and they have another problem. The technical achievement of these engineers is certainly notable, but everything indicates that they are still far from what NVIDIA and its competitors are achieving. like AMD or Google with its recent TPU Ironwood. There is another element that works against them: Chinese manufacturers continue without having direct access to the most advanced photolithography on the market, and although it also there is progress from Chinese manufacturers in that sense, competing is certainly complicated without access to the most advanced technologies. Pressure. In 2024 the company achievement revenues of 598 million yuan (73 million euros) with a net profit of 85.9 million yuan, but in the first half of the year the income was only 102 million yuan and had losses of 144 million yuan. The firm has reached an agreement with its investors by which it will have to go public at the end of 2026, or else it will be forced to buy back shares. The financial pressure is therefore notable for the company, which must demonstrate in the coming months that its roadmap is truly competitive. In Xataka | China was no longer supposed to be able to get its hands on NVIDIA’s most advanced chips. Until he found a shortcut in Indonesia

‘Stranger Things’ changed everything for Netflix. Your problem now is finding another brand just as powerful.

by

The expectation is through the roof: Netflix has just taken the first steps of the final season of ‘Stranger Things’‘, which will run throughout December with several episodes, many of them feature-length. In fact, the desire of the fans is such that Netflix even saw its servers falter. A (very possibly) triumphant culmination that, however, leaves a few unknowns in the air. Netflix flashes. Netflix experienced a service outage that in some cases It lasted about twenty minutes. (although the thing did not exceed about five, according to the platform’s official statement) with the premiere of the fifth season of ‘Stranger Things’. The incident occurred despite the fact that the series co-creator, Ross Duffer, had shared that Netflix would increase its bandwidth by 30% to avoid precisely this type of incident. All in all, thousands of users reported NSEZ-403 errors that prevented them from accessing the content, or accessed it with problems, which worked as a perfect thermometer of the expectation generated by the series. ‘Stranger Things’ continues to be a phenomenon capable of collapsing digital infrastructures three years after its previous season. Devastating figures. The fourth season accumulated 140.7 million viewsestablishing itself as the third most watched series in English on the platform, only behind ‘Wednesday’ and ‘Adolescence’. Of course, it is the only series with all seasons in the Top 10an unprecedented milestone on the platform. The impact on subscribers is more difficult to quantify: the third season, for example, contributed to add 520,000 subscribers in the United States. The cultural impact. The impact that ‘Stranger Things’ has had on modern pop culture is enough for a book, but let’s stick with some figures that will give us a rough idea. First, the economy: Netflix, for example, closed agreements with approximately 75 brands to promote the third season. Coca-Cola relaunched New Coke, generating 1.2 billion dollars in media value; Similarly, Nike obtained $178 million in media coverage with their Hawkins High collection. But this goes far beyond benefits for some brands: Butts County in Georgia, where the series is set, reported a 12% increase in tourism during the years the series was broadcast. And the small city of Jackson, with barely five thousand inhabitants and a per capita income of less than $30,000, revitalized its economy thanks to thematic tours. And of course, there is the strong role that the series has had in the recovery of the aesthetics and fashions of the eighties. It is no longer just that they have been revitalized Stephen King’s books and John Carpenter’s films: platforms like LTK registered increases of 3,000% in searches for clothing similar to those worn by the characters. What can we expect? For now, Netflix has planned very well to divide this final season into three: 4 episodes on November 27, 3 on December 26 and a final one on January 1. That is, coinciding with Thanksgiving, Christmas and New Year’s Eve, and thus, contrary to what is usual on the platform, stretching the cultural conversation for two months. As for audience expectations, as expected, they are very high: analysts predict new viewing records given the three years of waiting until this end. Of course, the critics have spoken and they point to the signs of exhaustion that were already seen in previous seasons: 87% on Rotten Tomatoesthe lowest rating of the series so far, although the audience rises to 92%. It is not easy to maintain narrative quality after so many years, with obstacles such as the age of the protagonists. The future. The really interesting thing about the phenomenon is wondering what Netflix has ahead. Or to put it more awkwardly: can the platform replicate the phenomenon? It has certainly had successful series in its catalogue, such as ‘Wednesday‘, ‘The Squid Game’ or ‘The Bridgertons’, but except for the first, all of them have finished or are about to do so. It is true that Netflix has the ability to generate new hits like ‘Wednesday’, which also, although it came as a bit of a surprise to everyone, could be well exploited by the platform. Now, Netflix is ​​in a phase of prioritize quantity over qualitymercilessly canceling what does not interest you and attesting that we are in a different moment than the initial success of ‘Stranger Things’: the competition has multiplied and it is more difficult to get noticed among multiple offers. Netflix has all the space in the world before it to compete, but perhaps its main rival is its own legacy: how to make ‘Stranger Things’ forgotten. The series was perhaps, before the almost infinite atomization of the offer of the streamingthe medium’s latest great global success. And that is very difficult to overcome. In Xataka | Netflix loved movie theaters. Then he hated them. Now you have reached a very beneficial middle ground

In 1982 Seiko created a watch for making calls and watching television. His only problem was arriving too early

by

History is full of devices that were ahead of their time. I am not referring to literary or cinematographic machines like the tablet by Kubrick or the multiple predictions from Verne, but to other devices that were put on sale decades ago and now we realize that they are very similar to some of the latest gadgets on the market. One of these inventions was Seiko TV Watch. In its day this rarity was considered and recognized as the smallest television in the worldand even made appearances in some movies, but today no one can miss its striking resemblance to current smart watches, and in a way we could say that we are facing a distant relative. The history of this device began in 1972, but the first step was not taken by Seiko but by another North American company called Hamilton. They were the creators of Press P1the first digital wrist watch in history. The Japanese they acquired to Americans, and they embarked on their own path into the digital age by launching their first watch of this type in 1973. At that time it was said that society was moving towards a revolution in visual information, and to join it with its new range of watches the japanese company started to work on the research and development of liquid crystal panels (LCD) with active matrix that were capable of reproducing moving images. Over the following years, these efforts helped their watches become increasingly smaller and thinner, with higher component density and more energy efficient. They were also implementing new functions such as stopwatches and calculators. After three years of development and hundreds of millions of yen invested, the summer of 1982 Seiko advertisement in Tokyo a new watch. It was about TV Watchthe first to finally allow us to watch television on our wrist. This was Seiko’s TV Watch A watch that you can watch television on. Today this concept seems simple, but back then being able to carry it out was a little more complicated. The TV Watch was made up of three different elements that had to be connected together for it to work. The result was a science fiction product, yes, but a little uncomfortable to wear. On the one hand we had the clock, but we had to connect it to a radio and television receiver the size of a walkman. We also needed headphones, and these also had to be connected to the signal receiver. And how could you carry so much cable with you in a fairly comfortable way? Well, very simple, pay attention to this drawing that appeared in your manual. As you can see, the trick was to put the receiver cable under the sleeve to connect it to the watch. But in case we didn’t want to complicate our lives, the TV Watch also had a function to listen only to the audio of television broadcasts. The watch itself had dimensions of 40 x 49 x 10 millimeters and a weight of 80 grams, and all its magic was concentrated in its innovative 1.2-inch white and blue LCD screen with a resolution of 32k pixels and 10 shades of gray. I also had a second smallest screen in which we could see the time, set the alarm and use the stopwatch as with any other digital watch. During the presentation of the device, its creators had to give certain explanations about how they had achieved such ingenuity. They said their new panels controlled the molecular arrangement of liquid crystal within an electric field, and that this made it possible to create miniature images with very low power consumption. Especially when compared to the cathode ray tubes of conventional televisions. The receiver measured 74.5 x 125 x 19 millimeters and weighed 140 grams. This made it too big to carry in a back pocket, but perfect for the inside jacket pocket. Its battery consisted of two AA batteries that gave it a range of five hours, and it tuned both FM radio and television on VHF & UHF channels. What could have been and was not The TV Watch arrived on the Japanese market in December 1982 with a single DXA001 model that cost 108,000 yen, although a second, cheaper DXA002 model was later released. The difference between the two was that the second included a hearing aid instead of headphones, and its price dropped to 98,000 yen. In exchange, these two models today would be worth around 600 and 500 euros respectively. The presentation of the device managed to generate a lot of interest, and the watch made front pages of newspapers and headlines on television. It was considered an innovative product for allowing us access a large amount of information in real timeand it attracted so much attention that a year later it also ended up reaching the US market. Errr, okay? During its launch in Japan, Seiko managed to sell 2,200 units, and the president of the company’s North American subsidiary said that the reception from the American media had been so good that he believed he could sell all the ones they manufactured. This optimism translated into the production of between 15,000 and 20,000 units ready for export. But not everyone saw the TV Watch as an invention destined to revolutionize the market. In fact, it is known that at Sony they came to say that their laboratories had the capacity to develop a similar product, but that They didn’t think there was a big enough market. for this type of devices. In the end it turns out that they were right, and the watch did not end up becoming a successful product. In the TV Watch curriculum we find several dates indicated. In 1982 he won the Nikkei Award for Superior Quality Products and Services, and a year later he made an appearance in Octopussythe new James Bond movie. The watch culminated its career in 1984 by entering the Guinness Book of Records as … Read more

China is sending drones to an island 100 km from Taiwan. The problem is that Japan and the US are filling it with missiles

by

The small Japanese island by Yonagunilocated just over 100 kilometers away from Taiwan, has gone in a matter of months from being a remote enclave with a modest self-defense detachment to becoming one of the most sensitive points of the strategic balance in Asia. The United States, China and Japan itself are carrying their disputes to the small enclave. An island as a front. The intensification of chinese drone flights over the island and the strait, intercepted on two consecutive occasions by Japanese fighters, has reinforced the perception in Tokyo that the first island chain is entering a phase of chronic instability. Japan, aware of the real possibility of a conflict around Taiwan, has decided to turn Yonaguni into a defensive node fully integrated: a place where operates a FARP American that extends the range of Marine Corps helicopters, where capabilities are consolidated electronic surveillance and where the installation of air defense missiles is progressing like the Type 03 Chu-SAM. Weapons and more weapons. This system, capable of tracking one hundred simultaneous targets and shooting down twelve of them with Mach 2.5 missilesimplies that Japan is beginning to give teeth to a position whose mere proximity to the democratic island makes it an advanced platform to detect, deter or even respond to a possible Chinese attack. For Tokyo, reinforcing Yonaguni is not a provocation but a life policy national: any attack on Taiwan, as as stated the new Prime Minister Sanae Takaichi, would constitute an existential threat to the archipelago. Yonaguni Beijing’s reaction. China, which interprets any Japanese defensive measure as one more step in a strategic siege promoted by the United States, has reacted with increasing hardness. From historical comparisons to veiled threats, including the summoning of the Japanese ambassador and the suspension of economic exchanges, Beijing frames the installation of missiles in Yonaguni as an “offensive act” that violates the spirit of the bilateral normalization of 1972. The rhetoric has gone in crescendo after Takaichi’s words about the possibility of Japan intervening militarily in the event of an attack on Taiwan, something that China considers a space invasion diplomat reserved for Washington. The climate has deteriorated to such a level that a Chinese diplomat even published (and removed) a direct threat against the prime minister, while the central government canceled meetings, stopped imports and called for boycott trips to Japansinking the influx of Chinese tourists who represented almost a third of foreign visitors. In parallel, China has intensified its military demonstrations, spreading videos YKJ-1000 hypersonic missile destroying Japanese targets, a message designed to emphasize that any expansion of the Japanese military footprint will be met with a response. The strategic dilemma. Far from backing down, Japan has adopted a tone unusually firm. Under the leadership of Takaichi, the political heir to Shinzo Abe’s strategic nationalism, Tokyo has made Yonaguni the tangible manifestation of a doctrinal turn: accept that Japanese stability requires preventing China from dominating the Taiwan Strait. from there the proliferation of radar installations, electronic warfare capabilities and additional plans that contemplate systems such as US Patriots, US Army Typhon, HIMARS and the NMESIS equipped with NSM missiles, capable of denying access to Chinese ships around the Taiwanese eastern coast. USA discreetly supports this redesign: approved sales of NASAMS and spare parts to the Taiwan Air Force, deployed CH-53E helicopters in Yonaguni (an unprecedented milestone) and coordinates with Japan a doctrine that assumes that, in the event of an outbreak of hostilities, the Marines must operate from the lethality zone itself of Chinese missiles. All of this positions Yonaguni not only as an advanced observatory, but as a critical point whose defense and survival would determine the first stages of any crisis in the strait. Yonaguni Taiwan’s hardening. While Japan reinforces the front line, Taiwan assumes that time to prepare is running out. President Lai Ching-te has announced a massive increase in military spending, raising it by $40 billion until 2033, with a roadmap that will place it at 3.3% of GDP in 2026 and with the declared ambition of reaching 5% before 2030. What Taipei is proposing is not a simple rearmament, but a comprehensive redesign: new missiles and drones, integrating AI into existing systems, protecting against infiltration operations, dramatically improving procurement (often delayed in the United States), and measures against transnational Chinese repression targeting Taiwanese abroad. For Lai, the most dangerous threat is not a Chinese landing but internal erosion: that Taiwan “gives up” due to psychological or economic pressure. It flatly rejects the “one country, two systems” model and affirms that the only way to maintain peace is to make an invasion too costly for Beijing. The United States, through its de facto representation, has described the decision as a crucial step to strengthen deterrence. A strategic powder keg. The juxtaposition of Japanese military movements, Chinese threats and unprecedented rearmament of Taiwan produces a “traffic” that raises the risk of calculation errors. The experts warn that a poorly calibrated comment, a overflight unreported or a maritime incident could accelerate a spiral that is difficult to contain, especially when Beijing tries to use its contacts with Washington to simultaneously pressure Tokyo and Taipei. In this context, Yonaguni becomes symbol and detonator: too close to Taiwan to be irrelevant, too exposed to be invulnerable, and too strategic for either side to relinquish control or influence. Plus: the island is both within immediate range of Chinese missiles and within the American concept of advanced distributed operationsmeaning it could be both a multiplier of Allied defense and a priority objective in the first minute of a war. A fragile balance. In short, China hardens his stanceJapan resignation definitely to ambiguity, Taiwan accelerate the shielding of its sovereignty and the United States consolidates its role as operational guarantor. In the midst of all this, Yonaguni emerges as a microcosm where the resistance of that regional order is tested. An enclave of barely 1,700 inhabitants that, due to its geographical positionhas become a thermometer, border and barrier. Its immediate … Read more

It is surely the best model for programming, but it still has a big problem

by

Anthropic has announced Claude Opus 4.5, its most advanced AI model to date. The company claims it is the best in the world for programming, intelligent agents and computing usage, beating OpenAI’s GPT-5.1 Codex-Max and Google’s Gemini 3 Pro. It has also arrived a few days after both as well as Grok 4.1. The general overview. The new model has achieved 80.9% accuracy in SWE-Bench Verified, the benchmark reference to evaluate software engineering capabilities. Anthropic has also put it through its own hiring test for engineers – notably difficult, with a two-hour limit – and the model has outperformed every human candidate who took it. Why is it important. This release solidifies Anthropic as a leader in AI tools for programming. Even Meta uses Claude for its internal Devmate code assistantdespite competing directly with the company in other areas. The improvements are not limited to the code. Opus 4.5 stands out in: Creation of documents, spreadsheets and professional presentations. Deep research tasks with multiple sources. Advanced visual and mathematical reasoning. Management of subagent teams for complex multi-agent systems. In figures. Additionally, Anthropic has drastically reduced the price of its API: from $15/75 per million tokens entrance/exit at 5/25 dollars. And the model is more efficient than its predecessors: In medium effort mode, it equals the performance of Sonnet 4.5 but consumes 76% less tokens. In high mode, it beats Sonnet 4.5 by 4.3 percentage points using 48% less tokens. The context. The company has introduced that “effort” parameter (low, medium, high) that allows developers to control how long and tokens invests the model in solving a problem. It is a trend that OpenAI has also adopted in its latest modelsseeking efficiency without sacrificing quality. In detail. Along with the model, Anthropic has updated its development platform and consumer applications: Claude Code Improves your planning mode: Asks clarifying questions before creating an editable execution plan file. As seen with the Deep Research on duty. Claude for Chrome is now available to all Max users (around $100-$200 per month depending on limits), allowing AI to manage tasks across multiple browser tabs. Claude for Excel opens to Max, Team, and Enterprise users, with support for charts, pivot tables, and file uploads. Endless conversations– Long conversations no longer run into context window limits thanks to automatic summaries. Yes, but. The big problem with Opus 4.5 and Claude in general is its usage limit. Even for Pro and Max subscribers of the first levelthe tokens They sell out quickly. They take five hours to restart from the first message sent. The Opus model, being the most powerful, is also the one that consumes the quotas the fastest. This is the main source of frustration for users who pay $20 or even $100 a month. Anthropic has slightly increased the limits for Max and Team Premium, but the experience is still far from what is expected in a service of this category. Between the lines. The release of Opus 4.5 restores balance to the Anthropic model family. For the past two months, Sonnet 4.5 was outperforming the older Opus 4.1, leaving little reason to use the more expensive model. Now, with three clearly differentiated models (Haiku, Sonnet and Opus), each one has a specific purpose in terms of cost, speed and capacity. And now what. Anthropic follows a clear strategy: position itself as the premium provider for knowledge professionals and developers, competing directly with OpenAI and Google in the field where accuracy and reliability matter most. But if you don’t solve the problem of usage limits, you risk frustrating the very users who could get the most value from the model.
