Their brakes have a lot of posture and little effective

by

No one doubts the effectiveness of the Xiaomi Su7 Ultra. But more and more details that make us ask ourselves if the most special sportsman of the Chinese firm dresses with too much paraphernalia. The last thing we know Apuna to it, with disc brakes that, in reality, hide a minimum size pills. Gold seems. But stop, it does not seem that in front of everything I should. And it is that the disassembly of the brakes of the Xiaomi Su7 Ultra has shown that what is hidden under its huge housing is, in fact, some little larger brake pills than those of a Seat Ateca. And, although its housing is huge and stands out behind the tires, the truth is that its brake pads seem to be infradimensive for the weight and power of the vehicle. “There is more decorative clamp that really brakes,” explain our partners from Motorpasion. Overheating. The clash of influencer tang zhu liao che behind the wheel From an Xiaomi Su7 Max, which mounts very similar brakes, already gave the alarm. Trying to look for his best time in the Shanghai Tianma circuit, the driver ran out of brakes due to an overheating problem, ending in the protections. The same has happened to an Xiaomi Yu7 Max in Tianjin V1 circuit, they report in Carnewschina. In this case, brakes came to support temperatures above 600 degrees which, again, caused overheating that left them unusable and even burned. Too small. Criticisms of Xiaomi do not come to lie about their brakes. What happens is that these do not seem to be prepared to endure cars of more than two tons launched at maximum speed in a circuit. This could be overcome but the truth is that the company has sold its xiaomi su7 ultra as a perfect car for circuit. To the point that he wanted to force his drivers to pass a test as if it were Gran Turismo. The point is that Xiaomi gives what it promises: Brembo brakes perforated with four pistons. However, its size is much smaller than its housing suggests. And that is a problem because at a lower disc size, It is more likely that overheating will be registered And, therefore, the brakes die along the way. And at a smaller pill size, smaller mordant. Too spectacular. It is not the first time that Xiaomi takes the colors because the elements of their electrical sports are more spectacular than effective. A few months ago, it was discovered that the competition hood that can be mounted on the Xiaomi Su7 Ultra It has no effect on driving And it is purely aesthetic. So, Some buyers demanded to the brand for deceptive advertising since they pointed out that it was one of the elements that allowed to achieve a better performance. However, the air intakes of the hood did not refrigerate any component directly and the company promised to withdraw the hood in those cases that, once the order has already been placed, they would not yet be delivered. Xiaomi defends himself. The most recent event with the Xiaomi Yu7 Max was recorded during a test in the vehicle circuit by various media. The driver, they count on Carnewschinadetected the problem in the brakes and decided to enter boxes to safeguard security. From Xiaomi, however, they defend themselves by ensuring that this happened because there was no warm -up return before the fast return and there was not a cooling turn before returning to boxes. This caused the combustion of small compounds next to the brake clamp but, according to its version, the performance remained optimal. They also explain that the return had not activated the Master Mode which activates a regenerative braking of up to 0.2 g that should help stop the vehicle making less use of the brakes. Is it so much? A little yes. And it should be borne in mind that the most powerful electric cars are, in their vast majority, huge cars because they need batteries that support their accelerations. And that forces to include brakes at the height. The companions of Motorpasion They compare Xiaomi’s Berlina with some rivals. They explain that the Chinese company does not offer concrete data of the size of its discs but it is estimated that they are around 320 mm in the Max and 430 mm versions in the ultra versions. A Tesla Model and Performancethat with its 530 hp they are far from the almost 700 of the Max and very far from the more than 1,500 hp of the ultra, it has a 355 mm discs, that is, larger than those of the Max version. A Porsche Taycan GTSwhich touches the 600 hp, mount 390 millimeters in front and 358 millimeters behind, with six and four pistons. But, above all, the difference is in the size of the pills. Not only that disc brakes are also smaller or are not so sized for power. The other big problem is that the size of the brake pill seems to approach that of a Seat Ateca instead of a supercar of more than two tons. And that, when you turn a circuit, it’s a problem.

I have tried the world’s first rolled laptop. Just get back to him to realize that it makes a lot of sense

by

Two years ago, Lenovo showed at the MWC a concept of roller laptop of the most curious: His screen expanded to convert a conventional laptop into one with vertical screen. We did not know if that device would see the light at some point, but as the folding laptops did, In the end he did. In the CES of this year, Lenovo confirmed that this rolled laptop was no longer a concept and became a commercial product. He was baptized as Lenovo Thinkbook plus gen 6 and today, finally, we have had the opportunity to try it first hand. Because? That is a question that is worth asking, why an enrolly laptop? The answer, luckily, is simple: having a laptop with a large screen is fine, but having a large screen with more vertical space is wonderful if we work with documents (text or spreadsheets), texts or code. The attempts to date had been shy, with laptops that left the 16: 9 format for Bet on the 3: 2. Lenovo has gone a step further. Rolled is a more or less conventional computer | Image: Xataka But unrolled is another story | Image: Xataka How is? At first glance it is a conventional portable device, only that the screen is somewhat more square than normal. When the panel is rolled, it is 14 inches and has a resolution 2,000 x 1,600 pixels, that is, 5: 4 format. By clicking a button (or gesture with the hand that does not finish going fine), the laptop is displayed up to 16.7 inches, the 2,000 x 2,350 resolution pixels and an 8: 9 format. Basically, a 50% larger screen. The third button starting on the right in the upper row is the one that goes down and uploads the screen | Image: Xataka The laptop takes about ten seconds to complete the up or down cycle. The screen, of course, is hidden under the keyboard and unwinds thanks to engines that, everything is said, are heard slightly. It is not an unpleasant sound or that will be distracted, much less, but it is there. However, I must say that the contact took place in a crowded room of people, so I had to approach a lot to notice the noise. Hypnotiza. The truth is that it is easy to get dumbfounded seeing how the screen goes up and down. I will not affirm or deny having been turned on by clicking the button every ten seconds like a child with a new toy. It is one of those technologies that attract attention and that suppose a breath of fresh air in a mature product category in which innovation usually goes inside. Even more in the AI ​​PCs era. Detail of the roller mechanism | Image: Xataka And how much does it endure? When the durability question, from Lenovo they explain that the roller mechanism endures 20,000 cycles. They are about 11 years at the rate of five daily cycles. In this case, however, it must also be taken into account that the screen is not only enroll and unwinds, but also folds when we close the laptop. Lenovo ensures that the panel will endure 30,000 opening and closing cycles. Anyway, in a contact as preliminary as this is not possible to confirm this. This is how the laptop is seen from behind when it is completely unrolled | Image: Xataka The wrinkle. One of the great evils of folding mobiles is the wrinkle of the fold. Although manufacturers make all kinds of juggling to avoid or reduce it, such as making a drop -shaped fold, the reality is that it remains visible and notable to touch. In the case of Lenovo laptop is exactly the same. The wrinkle shows and looks. Not only is it seen, but it causes flashes when looking at the screen from certain angles. In front, however, there seems to be no problem. In what angles, the wrinkle is more or less visible | Image: Xataka A system that feels robust. Although the device rises and that the part that rises is thinner the upper area, the device does not transmit a sensation of fragility. It does not give the feeling that we will leave if we put it vertically and incline it. Moreover, the thickness of the laptop, being superior to that of a conventional laptop, is not as high as one could imagine. Yes, it weighs more and is thicker, but neither as much if we take into account that inside hides an roller screen and a deployment mechanism. An interesting change. As someone who is writing and reads a lot, a lot, a lot throughout the day, this type of implementations are interesting. On a few occasions I am doing Zoom-Out to a PDF to read more content or juggling to be able to better read something than, on a vertical screen, I could read without problem. This device solves that problem of a stroke, although it does so at a price well above what any laptop costs. Image | Xataka This laptop supposes, or could assume, a paradigm shift, in the way we understand the laptops. Getting that extra space is a fantasy for those of us who use the computer for productivity (not so much to play, there does not make too much sense). However, accessing this device is not something available to everyone. The price issue. The Thinkbook Plus Gen 6 Cuesta 4,199 eurosa price that surely leaves it out of the reach of most mortals. Does it solve having to load or install a secondary monitor to have flexibility? It solves it, partially at least, but it does it at a very high cost. The technology is impressive and seeing it in operation makes it win. The device is undoubtedly unique in its kind. Now he has the challenge of convincing users, and that is a flour from another sack. Images | Xataka In Xataka | “The AI ​​is not a … Read more

The digital kit promises to digitize SMEs and freelancers and “give them” a Macbook Air. There is a lot of small print

by

On paper the Digital kit It doesn’t seem a bad idea. The government’s proposal, managed by Red.esgrants a series of subsidies to facilitate the “digital transformation” of SMEs and freelancers. Or what is the same: that small businesses and people “in self -employment” can for example have their website, their online store and even access the subsidy of a macbook air m4 that seems to leave “free”. Except that it does not go free. Not much less. Subsidies for digital transformation The program, promoted by Red.es and the Ministry for Digital Transformation and Public Function, aims to “digitize” SMEs and adapt them to new times. Source: Red.es Financing comes from the Next Generation EU program of the European Union, and to start it up they were established different segments of beneficiaries that depended on the size of the SMEs or whether you were autonomous. The calls for almost all segments have been ending over the last months, but there is one that remains active: that of segment III, dedicated to SMEs from zero to three employees and also autonomous. The maximum amount of the subsidy for this segment is 3,000 euros, and is divided into two items. The first, with a subsidy of up to 2,000 euros can be used to commission the development of a web page (“basic internet presence”) or an online store (“Marketplace”). The second, which is becoming a claim on social networks, is a subsidy of up to 1,000 euros for the acquisition of a “safe job”which normally translates into a PC or portable. An important detail here: you can not ask for only the computer for the computer, and this can only be requested as a complement to the subsidy for the website or online store mentioned above. To access the program and get those “digital bonds” of up to 3,000 euros the process, explained in a PDFIt is theoretically simple. Just access the web accelerapyme.escomplete a “self -diagnosis test” and request help Digital kit through the form of the Red.es electronic headquarters. From there we will have to get in touch with a “digitizer agent”which will be the intermediary through which this “digital transformation” of our business is carried out. It is they who provide us with services (or manage that a third party provide them) and that they also take care of the acquisition of the famous portable of 1,000 euros. It is possible to become one of these digitalizing agents through the aforementioned Electronic Headquarters of Red.es, and In another guide in PDF It explains how to log in. A digitizer agent tells us the reality of the digital kit program As we say, on paper everything seems correct, but in practice the digital kit program has become a source of controversy that affects both parties, both those who have asked for those subsidies and to those who have managed them. To know from within what is happening we have talked to Pablo F. Iglesiasfounder of the consultant Cyberbainers that among other things achieved homologation for the digital kit. He has suffered the “small print” of this project as well as a service provider as a couple of a person who requested them. After this time offering their services, he tells us how his feeling is that there were “too many used who have seen in the program a quick business opportunity.” It is a message that others have shared such as Jaime Gómez-Obregón, which explained in x How a microenterprise “sold” hundreds of digital kit projects by subcontracting websites to freelancers in South America, which ended up promoting “Business models of using and throwing”. Iglesias also indicated how there have been large companies that They have taken advantage of the program to capture new customers as part of your service offer. In both cases the impact has been mostly negative. There are many the Complaints in social networks that They speak of Scams Related and how it has been seen that frequently the quality of the web pages or online stores created was very low, they were often “clones” of other web pages with minimal modifications that did not justify the 2,000 euros of the subsidy. For churches there is another additional problem: “Although they grant, for example, 6,000 euros to your company, the categories are limited to maximum expenses. Insufficient expenses to provide a service of twelve months, which encourages, by the structure of the subsidy itself, that the quality of the service is very but very low … or an economic agreement is reached outside the digital kit contract.” Iglesias himself explained that with 2,000 euros it is practically impossible for someone to “make you a professional website, give you basic services of backups, maintenance and monthly SEO work for 12 months.” Even so, he emphasizes, this program has caused the foam “alleged marketing agencies that They are dedicated to riding clonic WordPress With free templates in an afternoon, financing with the digital kit. “Although these pages do not position well in front of the competition, in the eyes of the program they have fulfilled the work,” and as the type client to which they van do not understand anything in the digital world, because it cooks. “ Free laptop myth In recent days we have started to see frequently on social networks like Tiktok Publications of accounts that They talked of The easy What was it get a macbook air m4 “free” subsidized by digital kit. But all these messages are misleading advertising, since although the digital kit program subsidizes these teams, who want to take advantage of this option will have to be very attentive to the small print. To start, because That subsidy does not cover VATand here Iglesias points to how “the state always wins.” To get the laptop we have to ask both the subsidy of 1,000 euros for the “safe job” and the 2,000 euros for the creation of a website or, as many of those ads sell, the start -up of … Read more

There was a lot of money at stake

by

A few years ago we talked about the “Fasters“, that group of people who did not conceive of their favorite series to less than 1.5x. The same with the podcasts or the audiobooks. At that time, they were the exception, and when asked about social networks, people would be surprised and horrified at the possibility of enjoying the culture in that way. Today things have changed, and being “faster” becomes quite common: according to a survey of The Economist and Yougov31% of Americans between 18 and 29 years listen to audios for more than 1x. The greats of the Internet have made it very easy to accelerate everything. YouTube, Spotify or Netflix are Internet giants that They only do not compete against their direct competitorscompete against everything And all looking for one thing: Our sustained attention. They want us to spend more and more time on the platform, not only to prevent us from going to the competition, but because they loyalty more and generate more advertising income per user. In the case of Spotify, for example, earn more money when we reproduce podcasts (and it is common to accelerate them) that when we listen to music, because they save rights to pay the recordings. On YouTube the logic is similar: if we accelerate reproduction, we can consume more content at the same time. Thus the part is understood the success of rapid consumption of content: these companies and others not only implemented the speed of accelerating reproduction where before it was not so common (outside the audio), but they put the function almost at the level of relevance of pausar or advance reproduction. Thus, YouTube offers to tricks such as leaving the video clustered on mobile or on the web so that reproduction goes from 1x to 2x automatically. Life at 1x becomes slow. WhatsApp and Telegram know it, and in 2021 they implemented the possibility of Accelerate audios Of our contacts, something that a server values greatly. The feeling with the audios, as one of Your hateorsthere is “there is a lot of detour, pauses, unnecessary repetitions”, and accelerate them to 1.5x offers, in many cases, a more normal cadence of conversation. As in person, with fewer distractions. Personally, all audios are already reproducing them at that speed, and I feel that I do not lose attention, context or data of what my friends and family explain to me. The audios of some slow -speaking people are compatible with climbing 2x, but it is usually not comfortable. Accelerating everything so much has consequences: when listening again at normal speed, there is some feeling that people are “drunk.” This effect is extreme if instead of accelerating we slowly slow down. Fomo as a factor of a huge “savings” of time. To understand the effects of accelerating reproduction in different services it is very useful to remember its official figures. According to YouTube in 2022, its users They saved 900 years of video per day Seeing them faster of their original speed. For Linda Stone, researcher at the Digital Revolution, accelerate everything has to do with the phomothe fear of losing things, not to get to everything. TV, redoubt of respect for creative intention. Of the big platforms (Disney+, Netflix, Prime Video, HBO Max and Apple TV+), Netflix is the only one that allows us to accelerate its contents from the official mobile application. The rest, neither in mobiles nor on other platforms, perhaps following The reasons that Netflix alleged Not to offer the function on larger screens: “We have been sensitive to the concerns of the creators and we have avoided including larger screens, especially televisions.” Five years after releasing the mobile adjustment, Netflix still does not allow reproduction on the smart TV. YouTube does not take it that way, and among its adjustments the possibility of Vary the reproduction of 0.25x to 2x for 15 years. Do not destroy my work. The rhythm and assembly are key elements of series and films. That they are slow or fast is not a failure, they are a decision with which they reflect an intention. So the filmmakers consider that accelerating reproduction is something devastating for work. In the face of the joy of the “fasters” for being able to accelerate Netflix and “unnecessarily stretched” series, Peyton Reed (Ant-man) and Peter Ramsey (Spider-Man: Into The Spider-Ambverse) were clearly against implementing functionality, to which Aaron Paul joined, despite having worked with them in ‘The way‘. The effects. The Economist includes the position of different experts and studies regarding the phenomenon. The conclusion of researchers from the University of Waterloo in Canada was that consuming content up to 1.5x does not add cognitive differences with respect to doing so at the original speed. Yes, but. However, when we approach or overcome the 2x speed, the thing changes: the responses to the evaluation of students who had seen evidence at this speed were of much worse quality. Taking this into account, the striking thing is that YouTube is already offering the option to reproduce its videos to 4x speed to premium subscription users. The experience of a fan. My partner and editor of Xataka José García acknowledged in a talk among colleagues to have seen ‘One Piece‘At 1.5x speed, “in those scenes that I knew they were important, but in which they also did not contribute to me 10 seconds of intense looks”, while “what I knew was mythical (coffee for coffee growers: episodes 483, chapter 1,000 and 1,076, for example) left it to 1x”. And he did not have the feeling of missing anything with this concrete anime, because “the dialogues are relatively slow and total, I do not understand much Japanese, so with being able to read the subtitles it is worth.” He also points out that something like this was possible at 1.5x, while “A 2x was already another story.” Unlike what can happen to WhatsApp the audios, returning to 1x was satisfactory: “It was weird. He was accustomed to … Read more

The skeptics of the AI warned that we were exciting a lot and we did not believe them: the AI is tontal

by

GPT-5 is something better that GPT-4. The problem of that phrase is in the word “something.” Openai’s new “unified” model does not seem to represent the qualitative leap that many expected, and that The alarms have sounded again. One might ask what if the AI no longer becomes much better than it is now? But maybe that is already happening and the question is another: what do we do then? The climb works, but less. In 2020 a team of Openai researchers published A study entitled “Laws of climbing for neuronal language models”. They raised a kind of Moore law of the AI: the more data and computation dedicated to training models, the better they would be. That observation was clearly demonstrated when they launched GPT-3, which was 10 times larger than GPT-2 but it was a lot, much better than that model. Deceleration. Gary Marcus, professor of psychology and neuronal sciences at the University of New York, explained in 2022 That this study did not make much sense: “The so -called lawyer laws are not universal laws such as gravity, but simply mere observations that could not be maintained forever.” Even Satya Nadella agreed With this statement a few months ago in the Ignite 2024 event. And as we are seeing, their doubts have come true. The climb works and the models are somewhat better than their predecessors, but The deceleration seems to be there. But GPT-5 is not so bad. The truth is that GPT-5 has improved in relevant metrics. Those responsible for Epoch AI They evaluated His behavior in FrontiermathFor example. The results were a bit better than their O4-mini predecessor, but there were no big yield jumps. Even so, they highlighted how GPT-5 has been the first model to solve a specific problem as if “had fully understood the problem.” In the field of mathematics, GPT-5 behaves something better than its predecessors, but the difference is not radical. The most difficult problems (Tier 4) are still almost impossible for AI models. Source: Epoch AI. And think better. Another independent analysis of the ZVI Mowshowitz analyst He pointed out that although the GPT-5 base model It was correct without further adoits advanced variants (GPT-5 PRO and GPT-5 Thinking) were a substantial improvement with respect to O3-PRO and O3 respectively, especially when mitigating hallucinations. According to your data, “GPT-5 Auto” (the base version) seems like a poor product unless you use the free chatgpt plan “. The same what we need is a symbolic AI. The symbolic (“classic”) represents knowledge using symbols and rules, and is based on logic and formal reasoning to solve problems and make decisions. This type of AI He dominated the panorama From AI until 90, but the lack of notable advances made that discipline stagnate and live a winter of AI. “We leave” with the connectionist, the neural networks that represent knowledge through connections and weights of the nodes of a network of artificial neurons. This discipline was the one that gave rise to the ia generative and the overwhelming success of Chatgpt and its rivals. His surprising good behavior unleashed the current AI fever, But performance advances are slowing down. The skeptics of the AI redouble their speech. Analysts like Ed Zitron – more extreme – or Gary Marcus – defense of the symbolic AI— They have always warned of the exaggerated expectations generated by the generative AI. Even those who were instrumental in the creation of Chatgpt, such as engineer Ilya Sutskever, They warned of the scaling limitations. Reasoning models have softened criticism and are a great alternative for that apparent stagnation of standard models, but even with them the feeling is that AI will not go much further. Thus we will never get to an AGI. Thomas Wolf, co -founder and Chief Science officer of Hugging Face, reflected on the problem A few months ago and concluded that the IAS have become “a country of men who say yes to all servers.” For him things began to be disturbing: “To create an Einstein in a data center we do not need a system that has all the answers, but rather one that is able to wonder things that nobody had thought or nobody had dared to ask.” As this expert pointed out, the current AI does not generate (usually) new knowledge, and “simply fills the holes of what humans already knew.” The current AI is like a fantastic and very applied student, but that student does not challenge what has been taught. He does not question it and does not propose ideas that go against the data with which he has been trained. Yann Lecun, one of the pioneers of the AI, has already concluded on the current generative AI: It’s silly. Lowering expectations. The panorama is worrying for those who are investing billions of dollars in data centers or in training new foundational models, especially because that impact may not be as gigantic as they had forecast and promised. Ed Zitron indicated In The New Yorker that “this is a 50,000 million dollar market, not one of one billion dollars.” Marcus agreed. “50,000 million, yes. Maybe 100,000.” What happens if AI has stagnated. If it is effectively, what we can expect is that AI becomes a useful tool to save time and improve the result of certain tasks – it is doing it – but not to provoke That seismic impact In society and employment What personalities such as Altman, Musk, Amodei or Zuckerberg defend with their investments. If that happens we will undoubtedly have a powerful tool to do things better and faster. That was just what allowed us other fantastic disruptions such as the PC or the Internet. But many probably expected more. A lot more. And there is the problem. In expectations. Image | Levart Photography In Xataka | There are too many AI models.

Madrid needs to build a lot to relieve its serious housing crisis. You already have a (mini) plan to achieve it

by

Madrid You need housing. A lot of housing. If the city wants to solve its mismatch between supply and demand and thus stop The climbing Price that he has long suffered needs to strengthen his market. It is not a simple task. Over the last years the capital has Moved file for example to avoid the escape of floors towards the holiday rental or clear land in which Raise new houses. With that backdrop, his City Council has just taken an important step with which he hopes to create hundreds of households in a new urban widening. Objective: to stop one of the Great challenges of the capital. What happened? That Madrid has taken an important step that will allow (partly) to relieve one of its most pressing problems: The lack of housing. A few days ago the City Council advanced in the procedures to clear the situation of an area of 218,000 m2 located east of the capital, together with San Fernando de Henares and Coslada, and in which 700 houses will be built, 50% official protection. What exactly? Advance in the long bureaucratic journey that the project has to complete before the first stone is placed. Last week the Government Board of Madrid approved Submit to the public information process the Sector Plan for the ‘Development of the East-Esanche of San Fernando’. The objective: ultimately, order the land located next to San Fernando de Henares and Coslada to “transform” with green areas, services … and houses. The Governing Board also approved to send the document to the Community of Madrid to activate two other essential bureaucratic gears: the strategic environmental assessment and the territorial impact report. For now, the project already has a favorable report from the General Planning Directorate. Click on the image to go to Tweet. Where will it be built? East of Madrid. To be more precise, near the roads M-45 and M-50 and the Regional M-206, between the towns of San Fernando de Henares and Coslada. Towards the East limits with the Parque Roma-Coronas neighborhood (S. Fernando de Henares), to the Oste with Jarama (Coslada) and to the south beautiful with the hills (Madrid). The Consistory recalls that under the ground the Metro line 7 runs, not far away are the Central Coslada and S. Fernando. The idea is not to build only 700 homes, green areas and other equipment, but “integrate” the new neighborhood into the surroundings, especially with Romoronas Park and Jarama, “giving continuity and harmony to the whole set, also with the metropolitan forest,” Clarify José Luis Martínez-Almeida’s team. The Consistory wants to integrate the improved road into the urban framework, preventing it from acting as a kind of “barrier”. Why is it important? Because among other things the Ensanche of San Fernando plans to create about 700 new homes, half with some degree of public protection and the rest available for the free market. And that is an important news in a city that suffers a deep mismatch between demand and the supply of residences, which translates into a deficit that some voices of the sector They relate precisely with the lack of soil available for construction. The Association of Real Estate Promoters of Madrid (Asprima) Calculate that every year they are necessary 40,000 New households in the community, well above the production of new construction. According to their estimates, over the last years housing deliveries have remained between 7,200 of 2014 and the “peak” of 23,500 last year. In 2023 and 2024 he estimates that 16,000 and 18,600 began respectively, which gives an idea of the stage for the next few years. And what does that suppose? “There is much more demand than supply and that translates into a price increase. In addition, there is an embolized demand for more than 175,000 homes,” warned Real Estate Consultores Forum in a 2024 analysis. In its last year’s report, Asprime already remembered that the INE forecasts pass through that in the coming years (between 2022 and 2037) the population of the Community of Madrid grows almost 13% to exceed the 7.8 million inhabitantswhich will fully affect its real estate market, tensioning it even more. “This growth will cause the community to build housing in the next 14 years for 573,738 new homes, passing the housing park of the 2,636,988 existing in December 2022 until 3,210,726 of December 2037. It means building more than 40,000 homes a year, compared to the 17,000 that are currently built,” collect The promoters report. The collective is part involved, but it is not the only one who has warned of the hole, a problem that extends to other regions of the country and also has pointed out The Bank of Spain. Does it affect something else? Yes. The mismatch between supply and demand, added to other factors such as The pressure that holiday rentals exercise, it is felt on several fronts. For example, in The speed with which the floors find tenant or buyer or The hard conditions who are forced to assume those interested so as not to be expelled from the market. If there is a clear indicator of the imbalance it is nevertheless the price. Idealista calculates that M2 costs € 5,718 In the capital, 23.7% more than a year ago. In the case of rentals the rise was from 11.3%. Images | Quique Olivar (UNSPLASH) and Borja Carabante (X) In Xataka | In Madrid the number of Latinos has shot.

China is matching the West in a lot of technologies, but has already overcome something more crucial: research

by

Two years ago, in spring 2023, Springer Nature Editorial announced an expected Sorpasso. China had surpassed the United States in the Nature Indexan index created to measure the contribution to the scientific production of countries and institutions. It has been time for that and everything indicates that Chinese science, far from loosening the passage, has increased its distance from its main competitor. Solo leader. The last review of Nature Index Research Leadersthe “classification” based on the index prepared by the editorial responsible for the magazine Natureis A new test of the consolidation of Chinese institutions as a key piece in the global scientific research model. According to those responsible for the index, China achieved in 2024 an index of 32,122, a 17% increase Regarding the previous year, consolidating a first position that he achieved two years ago. From the company that elaborates the index it is also highlighted that the Asian country has eight institutions among the 10 most outstanding worldwide. Evaluating global science. After China and the United States, two European countries occupy the Third and fourth positionrespectively, Germany and the United Kingdom. Asian countries are also consolidated in the national “top 10”, with four countries represented (in addition to China, Japan, South Korea and India), matching the four Europeans in these head positions. The Chinese Academicia opens the List of institutions most outstanding scientists, followed by Harvard University and by the University of Science and Technology of China. The first Spanish institution that we can find in this ranking It is the Higher Council for Scientific Research, the CSIC. Nature Index. But what exactly is this index? He Nature Index It is an index Based on the contributions of scientists attached to various research institutions (whether public, private or companies). These contributions are measured through articles published in a sample of various high -impact scientific journals. Beyond Covid. In 2023 We pointed out That the leadership of Chinese science owed the work done by Chinese institutions in the fight against COVID, for example in the identification and sequencing of the virus some of its variants. However, we also pointed out that this advance also responded to a trend that had already been occurring since before the pandemic. After five years of the pandemic, the data seems to confirm the weight of this ascending trend beyond the situation of the pandemic. An ascent that is exclusive to this Asian giant but is also shared by other countries of the continent, such as South Korea and India, which saw increase in several percentage points (4.1% and 2% respectively) its contribution. This promotion of fact allowed South Korea to overcome Canada, standing in seventh position in this global classification of countries with the highest contribution to science. Tenth place. And what about Spain? The index of Nature Place Spain In thirteenth place in the global, sixth classification among the countries of Europe. Spanish science would be between Italian and Dutch, exactly the same as two years ago. The index in Spanish institutions. We pointed out at the beginning that the CSIC led the Spanish contribution to world science. The contribution of this public institution occupies a leading first place since its index (218) bends to the index of the second institution in the ranking National, the University of Barcelona (86), which is in position 245 in the ranking global. The third position at the national level is held by Barcelona Institute of Science and Technology (BIST).

Studying a lot is fine, but there is another factor that influences that you approve or suspend: the exam time

by

If you want to approve an exam, there is nothing more than study (well, or Use Chatgpt). Going prepared is the best insurance to get good note, but there is more. Some researchers have discovered That the exam time can also influence, and much, in the result. The study. It was carried out at the University of Messina, Italy. They took into account the exams that were made between the end of 2018 and early 2020. In total, more than 100,000 exams of 1,243 subjects. The approved rate was 57%, the curious thing was when they realized that there was a time slot in which the approved rate was greater. Better at noon. The exams were held from 8 in the morning until 4 in the afternoon. The time slot between 11:00 and 13:00 is where the approved rate reached its peak. If you are lucky enough to put the exam at that time, the chances of edges are higher. If on the contrary you have the exam at 8 in the morning or 3 in the afternoon, you may not take out outstanding. Because. The study does not delve into the causes, but researchers have a hypothesis: biological rhythms. One of the authors of the study affirms that the results show “how biological rhythms, often ignored in decision -making contexts, can significantly influence the result of high -risk evaluations.” Our cognitive performance is improving during the morning to reach a peak at noon and start its descent in the afternoon. The approved rate curve is clear: at noon better Fountain The chronotype The study also indicates that this could vary depending on the chronotype, something that has not been taken into account when obtaining the results. It refers to the natural predisposition of a person to have energy peaks and need for rest at different times of the day. Although we know that Genetics plays an important role in sleep cyclesit is also true that students usually study at night. A bad rest would explain that in the first hour the performance goes down. Exams and more. The researchers propose that the institutions concentrate the exams around the central hours of the day. Although the time of an exam does not depend on students, there are other evaluations where we do have some margin when arranging the time as a job interview, as They point to The Times. The researchers agree and leave the door open to study if the time also influences a better performance of the candidates and even the interviewers.

Hybrids have become the best selling car in Spain. Now we know how much it costs to change your battery: a lot

by

35.35% of the cars sold in Spain are hybrid. Last yearthe category of hybrids is the one that enrolled most vehicles and right now no other shades in our country. With June datain our country 254,604 hybrid cars have enrolled, by the 192,447 gasoline cars, the second category most purchased in our country. That has been possible by the little trick of the Microhíbridosthat add a small electric battery of very small dimensions, which slightly reduce consumption but, basically, allow manufacturers electrify models with very little investment. That investment, however, adds complexity to the whole. That is, greater problems if we have to make a repair. Because it is not only to replace a battery. In relation to its size, changing the battery of a hybrid is very expensive. And contrary to what we would expect, we will have to leave more money the smaller the battery. Small battery, large cost That is what the International Energy Agency That it states that last year, the average price of a 20 kWh battery pack for a plug -in hybrid had a cost similar to a 65 kWh electric car battery. This is explained for various reasons. The first is that in the report itself it is highlighted that the price of batteries for electric cars in China has been significantly reduced, falling the cost by 30%, compared to 10-15% on average that has fallen in Europe and the United States. Taking into account that China is the country where more electric cars are boughtthis has significantly decreased the average global price of batteries. The second reason is that the battery, large or small, have components that do not vary and, in addition, those of a plug -in hybrid need higher energy and energy density requirements because they are required more power (in relation to their size), which makes the product more expensive. The problem is that, as our partners of Motorpasionthis scale in reverse. The battery of a hybrid is more expensive to that of a plug -in for the same reasons indicated above. Adding that, in addition, many plug -in hybrids are bought (they enter the electric category), which reduces its price global medium. But non -plug -in hybrids are not bought so those prices are not reduced. And everything gets exaced when we get to cars Mildhybrid Or light hybrids, those that carry a small battery of 48 volts (or even 24 volts) and are already indicated as hybrid vehicles. In that case, the average cost of battery replacement is 2,000 euros but in some cars it approaches 3,000 euros if we add the labor. In MotorpasionThey put some interesting examples with 48 volt batteries. For example, within the Volkswagen Group, changing the Audi A6, A7 and Q8 or their sports versions S and RS entails an expense of 3,000 euros, of which 2,500 euros are taken by the battery. In a Volvo XC60, the change in this component entails the disbursement of about 2,000 euros. Prices are not as expensive as in non -plug -in hybrids but when we look at the price to disburse in relation to battery size. For example, the 1.2 kWh battery assembled by the Renault Clio, Captur, Arkana and Symbioz (But also the Dacia Jogger and Duster) It costs 3,500 euros in the official network of the brand. And if we go to the battery that rides the Renault Rafale1.7 kWh, we are already talking about about 4,000 euros. That is, the KWH price of this last case is 2,352 euros but, as we have seen, with that money in some cars of the Volkswagen group we would not change the 48 volt battery and in the case of the Volvo XC60 we would barely have money. In addition to all of the above, it must be taken into account that the replacement of the batteries is usually carried out in official workshops, so the cost of labor is usually superior. At the moment, there are not many independent workshops that are specialized in this type of breakdowns and although the data says that They are growingthe offer remains limited.

150 years ago we found a lot of rivets in a funeral mound. It turned out to be Norway’s biggest Viking ship

by

From series for all ages as’Vivky the Vikingo‘o The raw’Vikings‘, movies like’THE WARRIOR Nº13‘ either ‘How to train your dragon‘And video games like’Assassin’s Creed Valhalla‘ either ‘The Banner Saga‘, the Vikings have resisted fashions and the passage of time. And one of its most recognizable elements are its ships. They continue to cause astonishment And, among all, there is one that we discover by chance and turned out to be the king of the sea viking. The Myklebust. The finding. That mysticism and that it seems that they do not go out of style, contrasts with the barely 300 years that the Viking era lasted. Speak well of his legend, and ships like the Myklebust They are an essential part of it. Centuries after his era, in 1874, archaeologist Anders Lorenge gave some strange remains on a farm west of Norway. They were inside Randehagjen funeral moundon the Myklebust farm, and among many other things, he found a lot of rivets of a ship. Unfortunately, everything in quite a bad condition because the ship was buried after being cremated, which caused him to live in the shadow of other ships such as the Gokstad or the Oseberg that were found in perfect condition. But, over the years, we have been able to train more than an idea of how this king of the seas was. Ship? Cruise. As the excavations were carried out, the researchers found more rivets until they add about 7,000. Taking into account both the amount and their size, it is estimated that the Myklebust came to measure about 30 meters. And the estimate is not only based on the rivets, but on a very specific piece of the shields of the Vikings: the Umbo. This is the central circumference of the shield, which was probably placed along the ship next to the corresponding soldier/rowing. 44 umbos were found, indicating that, at least, there would be 22 shields per side. The Vikings had several ships, but those who entered combat were mainly three. On the one hand, the Karvia small ship of about 20 meters for the expeditions near the coast. On the other, the SNEKKEa great transport of about 30 meters designed for oceanic navigation and the transport of troops. Finally, the Drakkar. The size of these varies, but the Myklebust would fit into its description as a little draft ship, numerous oars and the bow with the dragon’s head. They were the most versatile ships because they were maneuverable, but with a large load capacity of warriors. Sagastad Museum with the replica of Myklebust and its sea access ramp Cremation. Due to its dimensions, the Myklebust was a symbol of power and had to terrify to see it on the horizon if it was not of yours, and in addition to its size, it had to belong to someone high. The reason why the pieces were very damaged is because the ship was buried after being cremated. In Vikingas tombs, the complete cremation of the ship was a strange and reserved practice only to the most powerful, like a king (it is speculated with Audbjørn de los Fjordos). In addition to the trousseau, jewelry, various objects and some hunting, the deceased needed a ship for his last trip to Valhallaand the Myklebust was that last means of transport. Returning to the seas. We do not know if its owner arrived at Valhalla, but what we do know is that the Myklebust has been furrowing the Norwegian waters for a few years. In Nordfjordeid is the Sagastad Viking Centera museum and attraction focused on the dissemination of Viking culture. It has several exhibitions, but the one that attracts more looks is the Myklebust room. In it, there is one Real scale recreation And with everything of detail of the war ship that can also navigate. The work began in 2016 and ended in 2019, and each spring opens the gate of that part of the museum so that the spectacular ship is dragged a few meters until it comes into contact with the sea. It is then that he undertakes a journey through the fjords, in an event that highlights the magnificent figure of this type of ships. But that replica can fall short if objects are still discovered on the site. A 2024 analysis showed more objects in the mound, such as a bronze ring and what can be more umbos, so perhaps we would have to rethink the expanding the drakkar for future tributes.
