solution

The radios of the battlefield are a trap for which it transmits. In China they think they found a solution

by

Use radio systems for communications in a hostile environment has always involved A technical risk: Issue energy means leaving a trace. Therefore, for decades, the challenge has been to find a system that allows you to transmit information without being detected. In China they could have achieved it According to SCMPresearchers have developed a solution that breaks with the traditional model: allows you to send data without issuing active signals. There are no radio pulses, nor do you make microwave. Everything is based on reflecting what is already in the air. The system takes advantage of the presence of radar satellites – like the Gaofen-3 and Ludi Tance 1– To use their own echoes as a means of transporting information. It is not what is issued, but what is reflected The key is on an intelligent surface formed by hundreds of programmable metamaterial tiles. When a synthetic opening radar (SAR) illuminates the goal – be it a tank, a ship or an airplane – these tiles manipulate the reflected signal by changing its phase: 0 ° when it is “burning”, 180 ° when it is “turned off”. That simple alternation allows you to encode messages directly in the radar echo. It is a system that modulates what comes to it. And it does it without preventing the radar from fulfilling its function: researchers say they have managed to maintain image loyalty with a loss of less than 10 %. The platforms that use it should be able to exchange information safely, avoiding revealing its position. Smart surface formed by programmable metamaterial tiles Making this type of communication work far beyond playing with reflexes. The main challenge was to survive in saturated cities of signals, where electromagnetic noise floods everything, and in agitated seas, where constant balancing distorts the reflected signals. The team led by Liu Kaiyu says that It has designed algorithms capable of raising the signal/noise ratio up to 300 % and inertial sensors that correct the movement of the platforms in real time. Metasuperficie of information combined with a passive wireless communication system For now, everything has been tested in controlled environment: laboratory, simulations and data analysis obtained by satellite. There is no evidence that this technology is deployed on the battlefield. But Liu’s team has clear plans: try the system with real platforms and validate its resistance to signal blocking. Its road map includes combining this technology with radars of multiple ways and creating an integrated network between space, air and floor. The ultimate goal is ambitious: build a safe communications system capable of working even in Scenarios with intense electronic warfare. The details of the investigation are available In an article published in Journal of Radars.

Playing video games in the middle of summer and with this heat is a horrible experience. I have found the solution in the cloud

by

Play on PC is very good Until summer arrives. To a hot room as is my office, the hot air is added that, desperate to compete against Cordoba heat, manage the six fans located in my tower. The feeling is … regular. If I leave the tower on the floor they end up warming my legs. If I upload it to the table, the noise of the fans becomes even more evident and the temperature increases equally. The same happens with the Rog Ally, console that I love But that if it already has quite high temperatures, in summer suffers even more. I have found the solution in a technology that generates opinions of the most varied and that personally, it seems to me the future: the cloud. The heat. Córdoba is currently in orange alert. The asphalt has reached 57.3ºCthe grass in the shade to the almost 27ºC and the maxims exceed 40ºC. I write these lines at 10:40 on Wednesday and we are already at 30ºC. At night it does not cool and opening the windows is like look at the doors of Mordor. Thus, the solution passes through air conditioning, fans and infinite patience. Image: Olivier Collet The components. Electronic components and heat They do not get along. Let’s say they are obliged to understand each other, but excess heat is not good for a computer or for any device. The cooling systems By air, which are those that usually assemble the vast majority of computers and consoles, will refrigerate depending on the ambient temperature. If in a room is hot, the cooling will be less effective than if the room is cold. Fresquibiris. In addition to cleaning the fans and the interior of the PC, which must be done as long as a quick solution could be to put the air-conditioning For a while to cool the room. The problem is that, on the one hand, it is possible that not all people have an air conditioning device in the room or that, on the other hand, the air conditioning is centralized and we have to put it throughout the house when we only want to cool a single stay. My case. I have a temperature sensor in the office. In the morning, at 8:30, the ambient temperature is 31ºC. If I put the air conditioning to work to reduce the temperature to 26ºC. If I remove the room, it ends up reaching 34ºC. Taking into account that the ideal ambient temperature is between 18ºC and 25ºC, you can imagine how pleasant it is to complete the expansions of ‘Guild Wars 2‘or shoot in’Delta Force‘On a PC that at 18:00 is already asking for clemency and mercy. I cannot compete against environmental heat, but I can stop the heat generated by the PC. As? Roughlymaking it work much more slowly. That, a priori, is incompatible with playing in a decent quality, and it is. Unless you do it in the cloud. GeForce Now | Image: Xataka Looking for the fresco. Playing in the cloud has a series of disadvantages that are evident: you depend on having Internet connection, you are tied to a subscription and Not all games are available. The advantages, however, are that the cloud is agnostic to the hardware (I can play in my tower, but also from the mobile, From the laptop used at the university or from the ROG Ally) and does not require the computer to be fully. Just an Internet connection. The game is executed on a server and we receive the image and send the inputs in real time. A matter of temperatures. To give a quick example, playing ‘Guild Wars 2’ in a room at 27ºC The temperature of the CPU goes from 55.4ºC to exceed 70ºC. The GPU, meanwhile, goes from 35ºC to about 55ºC. If I launch the same game, but in the cloud (Geforce Now in my case), the temperature goes from about 55ºC to 57ºC, while the GPU passes from 35ºC to 37.9ºC degrees. ‘Delta Force’ is not in Geforce Now, so I can’t play it in the cloud, but it comes to the hair to show how temperatures change. The processor goes from 55ºC to 68ºC, while the GPU goes from 35ºC to be around 60ºC. That is also noticeable in the noise of the fans, which turn at a speed far higher than when they are in Standby. Asus Rog Ally | Image: Xataka The Rog Ally case. Asus’s portable console is my header device to play titles like ‘Devil IV‘And even’ Guild Wars 2 ‘connecting it to a USB and HDMI hub. If you use it in performance mode (25W), the console reaches 80-85ºC with relative ease, not to mention the battery to make a breath. Playing at the same game in Geforce Now I can do it not only in better graphic quality and with more fps, but putting the console in Eco mode, with a temperature that does not pass from 55ºC, more silent fans and greater autonomy. That, in hand and long, it shows. In short accounts. If the temperature is a problem and we have good access to the Internet, the cloud can be an option if we want to continue playing without making more firewood. In addition, the subscription does not have to be eternal. It can be used during the hottest months and then play again when temperatures fall.

A quantum solution for black holes

by

The two families of physics They have not spoken for 100 years. Einstein’s general relativity describes with centenary precision The large-scale universe: how the planets, stars and galaxies deform the space-time fabric. On the other hand, quantum mechanics explains the strange and tiny world of subatomic particles. Both theories form the pillars of modern science, but are fundamentally incompatible. Unifying them in a single theory of “quantum severity” is, for decades, The Holy Grail of Physics. New research suggests that the key to achieving this could be hidden in the heart of the more enigmatic objects of the universe: Black holes. The impassable wall of physics. The problem is simple and the time incredibly complex. Quantum mechanics has managed to explain three of the four fundamental forces of nature: electromagnetism, strong nuclear force and weak nuclear force. Gravity, however, resists him. General relativity, our best theory of gravity, falls apart in the most extreme environments of the universe, precisely where quantum effects should be crucial. The clearest example of this rupture is the singularities, the theoretically infinite density points that are found In the center of black holes. For physicists, an infinity in an equation is an alarm signal that indicates that the theory has reached its limit. “We believe that general relativity only works on large or ‘macroscopic’ scales, but that in very short distances, or microscopic scales, it must be replaced by a quantum theory of gravity,” He explained to Space.com Theoretical physicist Xavier Calmet, author of a new study published in Europhysics Letters. A new recipe for black holes. Until now, string theory was the main candidate for this unification, in the absence of experimental verification. But Calmet and his team have adopted a different and surprisingly effective approach. Instead of a complete and finished quantum theory, they have used what is known as the “effective action of Vilkovisky-Dewitt” to calculate universal quantum corrections that should be applied to Einstein’s equations, regardless of the underlying theory. When applying these corrections, the team discovered something fascinating: in addition to black holes that arise from general relativity, there must also be holes born from “quantum solutions.” And it is not simple adjustments to the black holes we already knew. “They are completely new black holes that exist in a world of quantum gravity,” explains Calmet. New theoretical objects that emerge from the same mathematics, but with a quantum “flavor.” What all this means. Einstein’s relativity works great for huge things such as planets and galaxies (a continuous world); and quantum mechanics, for the tiny, like atoms (a world to jump). When it comes to explaining black holes, relativity predicts a singularity, an infinite density point that, in practice, tells us that the theory does not work anymore. What these physicists have done is to use a mathematical “patch” to add the basic quantum rules to relativity. This patch is the action of Vilkovisky-Dewittdeveloped by physicists Georgy Vilkovisky and Bryce Dewitt. In doing so, they not only fixed the “error”, but discovered that the new rules allow the existence of a completely new type of black hole, one that simply could not exist according to Einstein’s old rules. Can we ever see them? The study details how these solutions can be built near the events horizon, the border from which nothing can escape the black hole. Although these quantum solutions are theoretically different, distinguishing them from their classic counterparts is, for now, an almost impossible task. The most significant differences manifest very close to the horizon of events, a region that we cannot observe directly. “The astrophysical black holes that we are observing well could be described with our new solutions instead of those of general relativity,” Callmet concludes. “As both theories match great distances, it will be difficult to propose evidence capable of differentiating between the two types of solutions.” The theory shows that it is possible that There are black holes within a frame of quantum gravity. But the secrets of quantum gravity remain fiercely saved by these cosmic titans: the response to the greatest enigma of modern physics is not in a particle accelerator, but quietly orbiting in the darkness of space.

A work in front of Casa is unvoyable for everyone. China has a solution: inflatable domes

by

Anyone who has lived them knows: works can be as annoying as necessary. That they build a hospital, a school or a shopping center next to the house can be a blessing, but it is preceded by months and more months (not years) of dust, noise and a continuous coming and going of excavators, cranes and trucks. In China they have decided to save the neighbors that annoying toll of A peculiar form: covering the works with gigantic inflatable domes. AND (faithful to his style) He has also decided to do it in a big way. What happened? That China has had An idea so that the works generate less discomfort to houses, schools, parks, churches and other buildings that surround them: encapsulate them. Literally. Its proposal consists neither more nor less than inflarous ‘bubbles’ that cover the entire extension of the works, temporary domes that reduce noise and dust that the neighbors usually suffer when workers, trucks and excavators begin to move. The objective: less impact was while operators work inside. From theory to practice. The use of large inflatable domes is not exactly new. In autumn of 1971 Ibiza already hosted an ephemeral city created with plastic inflatables, Instant City. If the Chinese initiative is news, it is because of its approach (it seeks to minimize the impact of the works) and especially because it has gone from the theory to the facts. And big, in addition. In Jinana populous city of the East of China that acts as the head of the province of Shandong, just deployed an XXL inflatable dome as part of the Honglou 1905 project. According to Precise Huanqiuthe promoters want to build a large commercial complex there, but they found that the plot in which the works must be developed is in an area full of life, the district of Licheng, near a church, the Shandong University and an institute, in addition to numerous buildings. Thus, the question was obvious: how to get the works forward without the noise, dust, dirt and come and go of trucks to ruin the daily life of the entire neighborhood? An ephemeral ‘cathedral of 50 meters. The answer revealed it A few weeks ago Dazhong News: Those responsible for the work deployed a large inflatable dome 150 meters long, 100 wide, 50 high and a total area that moves between 20,000 and 30,000 square meters to cover the works. As is. The structure is formed by a PVDF membrane, a very fine material that operators deployed on June 12 with the help of fans. “The outside of the film is a network structure made of steel cables that keeps it together and then fixes it to the concrete beam at the bottom,” Wang Luren clarifiesHonglou Project Manager 1905. Under the dome there are no columns in addition, which allows operators to move comfortably. Click on the image to go to Tweet. Less dust, less noise. Those responsible for the work ensure that the “ bubble ‘reduces dust emissions by about 90% and cushion in more than 80% the noise of the works. It is also water resistant, which facilitates work during rainy months. However, the idea is that the dome is used during the first phase of the works, while the work progresses at zero level. For now, it has already served the government to breastfeed. A few days ago none, spokesman for the Foreign Ministry, He presumed that Jinan’s inflatable dome is “the largest in the world.” And insisted: its purpose is to “create cleaner and more silent construction spaces, minimizing the impact (of the works) in the surrounding communities and the environment.” To emphasize the message he published a video of the deployment that have reproduced media such as TN either Gulf News. And what about workers? The dome may reduce the discomfort of the works between the neighborhood, but … how does it affect the operators that will work inside? If dust and noise do not go outside, do they accumulate in the structure? Won’t it affect temperature? The initiative has raised similar questions, but the promoters ensure that the bubble is also designed for workers. “Avoid high temperatures” .Luren says that the PVDF membrane blocks 90% of ultraviolet rays and the structure includes a breathlessness at the top to guarantee ventilation. “We will also adjust the construction cycle to, as far as possible, avoid high temperatures.” A spray system and fog cannons will also help the accumulation of dust under the membrane staying at “a reasonable level”. The roof is also igniphed, is designed to support storms and snowfall and is completed with a system that allows their responsible to adjust the environment.

China has been wondering what to do with its 300 million pensioners. It has a “voluntary” solution

by

It We count last year. In Europe we don’t stop Find a formula that Relieve the situation of retirement and pension of people. But nothing that happens in the continent resembles what happens in China and its 300 million pensioners (and other hundreds that are projected in ten years). The country has made a decision to stop the problem: gradually upload the retirement age. Gradual increase. China thinks Gradually increase your legal retirement age in the next five years to try to deal with the aging of its population and the increasingly suffocated pension system. An action that is part of a series of resolutions adopted at a high -level five -year meeting of the Communist Party, known as the third plenary. An enlightening fact before giving context to the serious crisis of the Asian country: life expectancy has now increased above the United Statesuntil 78 years, and was only 36 years at the time of the communist revolution in 1949. A crisis of several fronts. The country has a problem: Society ages. With an economy In decelerationa long time since demographic crisis symptoms were felt. Last year, China lost for the second year consecutive population. Meanwhile, on the sidewalk in front, the figures indicated the lowest birth rates since there are records. All this assumes that the population of age to retire, One of the casualties in the world (60 years for men, 55 for women in administrative work and 50 for working class women), it only grows. In 2022 it was 280 million, last year of 297 million (21% of the total census). Worse. There are forecasts that speak of other 300 million projected In the next decade, and for the middle of the century there is talk of a population of 60 years or more than, at least, will exceed 500 million (almost 40% of the total register). In fact, forecasts talk about four workers for each retiree in 2030and in 2050, only two. Gradual retirement by phases. The entire scenario described above leads us to the news that has been confirmed and that has been brewing months ago. “According to the principles of voluntariness and flexibility, we will move constantly and orderly in the reform to progressively delay the legal retirement age,” The Communist Party of China explained last Sunday. The plan, together with some other key reforms, was published in a resolution three days after the country’s leaders concluded the third Plenary of China, an important political meeting in Beijing that takes place every five years. What we know. The truth is that it has not been specified how much retirement age or when, but A report on pension development From China published in late 2023, he explained that “65 years may be the final result after adjustment.” The plan has been at stake for some years, as China’s pension budget decreases. If it serves as a track, in 2019 (and before the pandemic) the cabinet had predicted that the Chinese Pension Fund It would run out in 2035 due to the decrease in its workforce. Years of strong restrictions related to pandemic have further reduced the coffers of local governments and, as they explained, “they could further aggravate the pension deficit.” At the same time and as we said, the huge population of the country has decreased for the second consecutive year in 2023 as the birth rate falls. Doubts. As for those somewhat “diffuse” terms, especially in the case of a capital issue such as pensions, the Global Times state newspaper cited demographs of the country saying that in the plan to increase retirement age, it stands out “voluntariness” and “flexibility”. It is impossible to predict how far that apparent decision of the Chinese citizen would achieve, but what seems clear is that the authorities recognize that there is no unique policy for everyone when it comes to retirement. Skepticism. That is the word that now defines the plan between Many Chinese usury on the Internet. Of all the doubts expressed, one that is repeated. “Those who want to retire in advance are exhausted by their laborious works, but those who perform comfortable and lucrative functions will not choose to retire. What kind of work will end with the youngest generation?” A user comments on the Weibo Networksurely exposing one of the key issues that nobody has yet explained.

Germany believes having found the most German solution to its productivity problems: work more

by

Germany has been considered for decades as The economic locomotive from Europe. However, currently It crosses a crisis that has surprised analysts and experts. The model that allowed the country to prosper with reduced working hours and shoot its productivity, seems to have reached its limit. German leaders They look for new formulas To recover lost growth and have found a possible solution: work more. Germany works little. In recent months, the economic debate has intensified without the German responsible having found the key to getting out of the economic stagnation. However, from the business circles of Bavaria, southeast of Germany, they point out that it could be something as simple as increasing annual work hours. The formula: eliminating one of the religious holidays of the German calendar. According to published the newspaper Welt, Federal Foreign Minister Friedrich Merz would agree with this statement: “In this country we have to work more and, above all, more efficiently,” said the president in a few words that Later he clarified “But in Germany we have groups, especially among the youngest generation, which work a lot.” They have tried everything. The pilot tests of the four -day work week They have not achieved the Productivity impulse that the country needs. Foreign Minister Merz recently warned: “With the four -day week and the balance between professional and personal life we ​​will not be able to maintain the prosperity of this country,” declared The German Chancellor to I monde. This statement has generated discomfort in a society that has always been considered hardworking and disciplined. For decades, German workers have enjoyed shorter working hours compared to other European countries, especially those in the south. This situation was justified by high productivity and added value of German products and services, which allowed “doing a lot.” However, the economy fails to take off and the government now points to “lack of work” and “preference for leisure” as factors that are ballasting economic growth. Eliminate holidays. Before this panorama, some voices of the business have proposed concrete measures to increase the working time Without increasing working days daily, which in many cases are already more than 40 hours due to the enormous load of overtime. According to published BildBertram Brossardt, general director of the Bavarian Business Association, suggested to eliminate, at least one of the holidays that the Germans have. “Easter Monday, Monday of Pentecost and San Esteban. My colleagues in France and Italy are constantly surprised that we have those free days. Removing one of those free days would greatly benefit the German economy and would not mean a heavy burden for employees,” said Brossardt, adding that “religious festivities should not be taboo in the debate.” The data support it. The proposal is not just symbolic. Christoph Schröder Researcher at the German Economic Institute (IW) He maintains that Eliminating a holiday could increase the Gross Domestic Product (GDP) of Germany by up to 8,600 million euros. According to published The avant -gardeMichael Hüther, director of the IW, gave as an example the case of Denmark, which had recently eliminated a holiday “that was an additional income of 400 million to the state budget,” said the economist. The problem is that all federal states in the country, regardless of setting their own holidays, should agree to abolish it. Germany to the tail at hours worked. Brossardt’s arguments rely on blunt data. In 2023, a German employee worked an annual average of 1,343 hours, which is 92 hours less than in Austria, 186 hours less than in Switzerland and 391 hours less than in Italy, According to OECDE data. “We are not productive enough. If we want to be competitive, we have to return to work more!” said The businessman to the newspaper Bild. Despite these figures, Germany is not the country with more holidays. On average, the Germans enjoy 9 national holidays, although in some southern regions such as Bayern, Basen-Württemberg or Saarland can reach 12 holidays. In comparison, Austria and Malta enjoy thirteen holidays. In Spain, the usual are twelve, with some autonomous communities such as Catalonia, Community Valencian and Navarra add 13 holidays; Ceuta has 14 holidays a year, while the Canary Islands conform to 11 days. Average weekly hours worked in each country The problem is not the days. Such and as he published The confidentialsome experts do not believe that eliminating a holiday is the solution for the German economy, but that the country must face a change in its labor market to recover the productivity of yesteryear. Germany is the second European country where less hours work a week in full -time jobs, and the figure drops even more if the Part -time contracts. According to official dataone in two women works part -time in Germany. Therefore, some economists propose Encourage the incorporation of women to the full -time labor market and facilitate the arrival of more foreign workers to relieve the shortage of qualified labor. The key, according to these experts, is a deep review of the German labor market to adapt to the new challenges economic and demographic that supposes the Agence of the active population.

How to predict the next epidemic? For researchers the solution is very simple: using AI

by

It arrives with heat, sneaks without invitation and leaves its trace on the skin: a red mark, an insistent itching, a sleepless night. The mosquito does not need a presentation; His buzz is part of summer. Now, we share our life with another invisible being: artificial intelligence. Silent, precise, without wings or sting, has begun to fight a battle with the old enemy. And in this story, only one can stay. The battle. A team of researchers from the University of Southern Florida, led by biologist Ryan Carney and computer engineer Sriram Chellappan, They have developed An intelligent surveillance system that uses artificial intelligence to identify, track and combat the most dangerous mosquito of the moment: Anopheles Stephensian urban vector of malaria that has already begun to expand in Africa. A unique method. The project key is to join advanced technology with citizen participation. On the one hand, they are developing intelligent traps equipped with artificial intelligence, capable of attracting, capturing and automatically identifying mosquitoes. On the other hand, the project relies on mosquitodashboard.orga global platform released in 2022 that collects photographs of mosquitoes sent by people from their mobile phones. Thanks to a visual recognition system, the panel identifies the species and generates in real time an interactive map that helps scientists follow the trail of the most dangerous vectors. And why? Chellappan team has developed unique algorithms capable of identifying a mosquito with only one photo, automatically recognizing its head, thorax, abdomen, wings and legs. This anatomical classification allows to distinguish species with great precision, even in challenging conditions. As He explained To Reuters, the advance in AI has allowed to identify where the diseases carrying diseases are because then the public health authorities can go there and launch control efforts to prevent new outbreaks. A global alert. Behind this technological deployment there is a real urgency, since mosquitoes such as the malaria transmitter are adapting and surviving in urban environments. However, there is a solution, because researchers have estimated for Reuters that smart traps could be manufactured for less than $ 150, which would facilitate their massive distribution as an early warning system in vulnerable regions. A war with many fronts. Although artificial intelligence promises to revolutionize the fight against mosquitoes, it is not enough by itself. “It will require more than one strategy,” He has warned Entomologist Tom Mascari in statements to Reuters. Technology is a key ally, but does not replace traditional measures such as the use of repellent. What is coming. In the next five years, the Carney and Chellappan team has planned to improve its algorithms, incorporate more species into the system and train a new generation of African scientists. The idea is that the fight against mosquito does not depend only on technology, but also on international knowledge and collaboration. And, perhaps, for the first time, the buzz of summer is not only a nuisance, but an opportunity to anticipate the enemy.

Europe fails to find the perfect solution for cross -border payments. Bizum and Banco Santander have just put it on a tray

by

Santander has become the first Spanish bank that allows its customers Send Bizum to other European countries. It is something that is achieved thanks to the interoperability between Bizum, Bancomat and MB Waya connection that according to the bank will connect 50 million users and 186 financial entities. It is a first step waiting for a unique pawous solution for which no agreement is reached. The first in Spain. Banco Santander has formalized the possibility of sending money through Bizum in a cross -border way. The agreement has been necessary between different payment solutions such as Bizum (Spain), Bancomat (Italy) and Mbway (Portugal), being limited instant payments to these two countries, for the moment. After performing the corresponding successful pilot tests, the clients of this bank will be the first to be able to pay outside Spain. The method will be the usual: we will only have to write the mobile number of the user to which we want to send the payment, and this will be carried out immediately and without commissions. It will not be alone. Santander has been the first to move token, but the possibility of sending Bizum out of Spain will be a standard before summer. Abanca, OpenBank, Caixabank, BBVA and Banco Sabadell are advancing in the implementation of this service, planned for the second quarter of 2025. It has not been thanks to Europe. While Europe Follow in search of a unique solutionthe private company moves record. Cross -border payments are possible thanks to the European Initiative (European Payments Alliance), a joint project initiated by Bizum and followed by both Bancomat and MB Way, with the aim of adopting instant transfers paneuropeas using existing infrastructure. In other words, it has been necessary for those responsible for the platforms to agree, in the absence of a European alternative that encompasses. The European Bizum. The European Central Bank has been trying to advance in a system of instant payments to interconnect the different member countries. But he doesn’t get it. During the last two years we have seen progress as Free transfers in Europe, Tests with digital purseand brushstrokes on a “European Payment Initiative” which has barely advanced since 2022. Countries like Spain They make 95% of immediate payments with Bizumbut this is not the only name that sounds as a candidate for possible means for European payments. There are those who try strongly. Solutions such as Bizum, Bancomat, BM Way or Swish were born as responses to the national need to be able to pay freely and free. The problem for the EU? None have been thought from scratch as a single payment solution. This is where solutions such as Weroa proposal towards “a unique payment solution, all in one, instantaneous and paneuropea, capable of covering over time all cases of payment that consumers and professionals require.” Banks such as German and French They are already promoting this servicenot yet compatible with solutions like Bizum. Nothing clear. The ECB points out that “instead of combining strength and sharing resources to develop paneuropeas solutions, national communities have often preferred to preserve the legacy of the investments made in the past”, an attack on models such as Bizum and a clear look at proposals such as Wero. With many delays and few proposals on the table, the road to a “European bizum” continues to draw distant. But, meanwhile, in Spain we will not take to pay with virtually any bank outside our borders.

Spam calls are a problem for everyone and Apple knows. Its solution with iOS 26 has been stopping braking

by

The mobile sounds and is an unknown number. The possibilities that there is a commercial wanting to sell you the last superooferta fiber They are high Or, in the worst case, it could be a Stofler getting through your bank. We have been talking about the problem of the so -called spam and fraudulent and so far no one has found a 100% effective solution. Yesterday Apple introduced us iOS 26a renewal that We have already been able to try And with a novelty that goes in this line, although the solution they propose is much more aggressive than those of the competition. The problem of unwanted calls. Commercial calls bother. They are abundant and it seems that they have the ability to call us when it comes to us. Even the government has taken letters in the matter and for a few days, Commercial calls from mobile numbers 600 or 700 are prohibited. But beyond wakeing us from the nap to improve our light rate, the real problem is in telephone fraud. The Fraudulent SMS They are incessant, but the scams also come by call. Through techniques of Vishing and Telephone spoofing We have seen how They can empty the account by passing through your bank. In view of such elaborate scams Both entities and the government have begun to take the problem seriouslybut despite efforts, we still can’t talk about the definitive solution. How the Apple call filter works. iOS 26 It will bring news in the telephone app and one of them is the call filter, which in Xataka we have already tried. If you receive a call from an unknown number, the iPhone automatically activates what they call live voicemail that asks the interlocutor who it is and the reason for the call. Once you have identified, the call appears on our screen and we can see the details that you have facilitated, so we can choose whether to respond or not. If we do not respond, the iPhone will tell those who call us that we are not available and will allow you to record a second message. By the way, whoever attends to the phone before us is Siri’s voice. This is how the calls of unknown numbers appear once the iPhone requests more information. Apple’s proposal is very different to what we were seeing in the competition. Here there is no filter as such, if we activate the live voicemail will affect all calls that reach us with unknown numbers. The only thing we can choose is whether the calls will be referred to Siri to request more information, to the voice mailbox or go to the list of unknown numbers. The configuration options offered by Apple. He Approach Android is more flexible and intelligent. A long time ago Android has functions to fight telephone spam. If we use Google’s APP we have different tools to fight with unwanted calls. It has a call identifier that tells us if they call us a business that is in the Google database and also If a number is suspicious of spam. Nor is it infallible and there are times when any call is sneak. If it happens, it allows us to mark the number as spam. As exclusive to the Pixel we have Call Assistwhich works similarly to Apple’s live voice mailbox. If we choose to filter the call, Google Assistant will ask about the reason for the call and will offer us a transcription. There is much similar, but an important difference: we choose what to filter and on the screen we will see before if a number is suspicious of spam, while Apple treats the same to all unknown numbers. This will alert Android of the scams. Image: Google With Android 16Google wants to go further and will be implemented Functions focused on fighting with telephone scamshow to prevent us from deactivating Google Play Protect or install apps from the browser. He will also be able to detect financial scams and alert us with a notice on the screen. Collateral damage. Apple sells its call filter as the solution to eliminate interruptions and in this sense is effective, but it can also be a problem because not all calls of unknown numbers are disposable. How many people will hang when listening to Siri’s voice asking why he calls us? Even though it is normal, it is still very unhappy and even counterproductive in certain scenarios as an emergency or if the doctor calls us. An intermediate solution. As we said, Android is not infallible blocking spam, but it does have some intelligence behind (and more will have when Android 16 arrives), while Apple opts to stop braking. Perhaps the exit is to find a solution halfway between the two where we can have more flexibility when limiting calls without risking to lose some important.

Ukraine has found the solution to produce three times more weapons than you can buy: the Danish model

by

It was known that Ukraine had raised a drone industry in front of the Lack of help. What was no longer known was that, since Russia launched its large -scale invasion in 2022, the Ukrainian defense industry had experienced a Explosive growthmultiplying its productive capacity by 35, from 1,000 million to 35,000 million dollars in annual potential. The problem was that, that the “potential” had no exit due to lack of financing. Until now. Lack of funds. As we said, this immense development Not only has it covered large companies, but also small workshops that operate even from particular garages, adapting to the needs of the battlefield. However, and despite this growing capacity, the country is limited by the Lack of financing: The state budget only allows to hire about 11,500 million in weapons, which leaves more than two thirds of the idle industrial potential. In fact, companies in the sector and senior officials They coincide in Insider in which, if there were the necessary funds, Ukraine could triple your production Armamentistic, thus reinforcing its resistance and reducing its dependence on foreign suppliers. Now they think they have found the solution in Denmark. The Danish model. To solve this paradox, the Ukrainian industry has proposed a small -scale solution: the call “Danish model”. This formula, applied by Denmark since 2023, allows allied countries Buy directly Weapons produced in Ukraine, instead of sending them from their own arsenals or acquiring them to Western suppliers. This way not only Reduce costs and accelerates the delivery of material, but also guarantees that the soldiers receive exactly What they needmanufactured according to its tactical demands and with an optimized logistics. Several countries have already added to this approachand others, like Germany, work in own adaptations. Thanks to this formula, Ukraine has been able to increase the production of key systems such as Bohdana self -propelled obúsand already has a list of weapons (including artillery and armored vehicles) ready to manufacture if more funds are channeled under the scheme. Collaboration and alternatives. Although the Danish model represents the road faster and fasterIt is not the only one. Serhiy Goncharov, president of the National Association of Defense Industries of Ukraine, and other leaders of the sector have also raised more complex models, based on co -production and the co -production and the Financing of Ukrainian weapons which include European components. This formula, although slower, could be attractive to a European industry that is also expanding its capacity Before the fear of A Russian expansion In the continent. In addition, the use of frozen Russian assets as a source of financing and the establishment of industrial alliances for technological transfers is considered. So much, Goncharov warns That many Western partners still do not expand their defensive capacity with the urgency that the situation requires, and that Ukraine, therefore, has no choice but to continue growing on its own to meet their own needs. Strategic opportunity Collaboration with Ukraine not only represents a way of supporting his defense in the short term, but a strategic opportunity For allied countries. The Ukrainian arms industry, born and adapted in the midst of the conflict, accumulates a direct experience in combat that is invaluable for any military power. Let’s think that your constant contact with the front allows you to adjust the design and performance of weapons based on the real conditions of the battlefield, something that many Western industries cannot replicate with the same speed. In that sense, associating with Ukraine offers Europe and other regions a double advantage: strengthening an essential supply line for Kyiv and learning from a military ecosystem that has proven extraordinarily Resilient, innovative and effective under pressure. As Goncharov concludes“We do not choose to be at war, but that is our reality,” and within it, the production capacity is ready.
