sense

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

If drinking milk makes sense or not

by

“Drink milk if you want to grow strong,” this was one of the many most repeated phrases in childhood, almost like a dogma. But, once adults, are it true? For some, the glass of milk before sleep is a nostalgic pleasure; For others, a expendable and even problematic product. The truth is that milk is in the center of a debate in which nutritionists, doctors and scientific studies do not always coincide. Can you continue drinking milk? The short answer: yes, provided there is no allergy or intolerance. This has been explained by the Nutrition Dr. María Ortega, from the Complutense University of Madrid, In an interview for Men’s Health: “Discharge from dairy products without justification is a mistake. It is difficult to achieve the contribution of some adequate nutrients without dairy.” Along the same lines, the dietitian-nutritionist Julia Farré He recalled that milk provides proteins of high biological value, calcium and vitamins A and D. However, like They have underlined Giuseppe Russolillo and Leticia López in Cidateplus, the answer also depends on food culture and genetics. In Europe, dairy consumption has been entrenched for centuries, which has resulted in a lower prevalence of lactose intolerance. Milk defenders. From this perspective, Ortega has underlined its protein value: 80% casein, slow absorption, and 20% dairy, rapid absorption. This combination guarantees a constant supply of amino acids. Although that is not all. The Healthline portal duck That milk provides 18 of the 22 essential nutrients, such as calcium, phosphorus, potassium and vitamins A and B12. In addition, they link it with greater appetite control, prevention of type 2 diabetes and cardiovascular health benefits. For its part, Dietitian Vedika Premani He recalled in statements for Vogue That a daily glass of milk remains a good ally against osteoporosis and the loss of bone mass in adulthood. While dietitian Sara Langnas, she stands out as a useful recovery drink after physical exercise thanks to her protein and carbohydrate contribution. Not all experts are enthusiastic. Here come the cons. CIBEROBN researchers have observed in an investigation that a high consumption of whole milk was associated with greater cognitive impairment in adults with cardiovascular risk. The association was not found with low fat, yogurt or cheese. From Harvard, professors David Ludwig and Walter Willett They have questioned the recommendations of three daily dairy rations. In an article in New England Journal of MedicineThey pointed out that countries with greater consumption also register more hip fractures. In addition, they warned of a possible relationship with greater risk of prostate and endometrium cancer. Not everything is cow’s milk. In recent years, vegetable drinks –soja, oats, almond, rice – have gone from being a resource for lactose intolerant or vegan to becoming one more option. However, As my partner explained in Xatakamost of these drinks contain less protein and essential amino acids than milk, and in many cases more added sugars. This is the result of the Maillard reaction that occurs during the ingredients, reducing the final nutritional value. Dietitian Julia Farré has pointed out In which these drinks, unless they are fortified, usually provide less calcium, vitamin D and quality proteins than animal milk. Even so, As experts cited by Vogue have explainedthey can be a valid option when enriched versions are chosen and, in addition, they have the argument of environmental sustainability, which weighs more and more in consumption decisions. And lactose intolerance? Beyond benefits or risks, one of the most determining factors is individual tolerance. Lactose is the natural sugar of milk and is digested thanks to lactase enzyme. As has detailed Leticia López in Cuidateplus: “Phylogenetically the natural would be to lose this enzyme with age, but a genetic polymorphism allows many people to continue producing a lifetime.” Therefore, lactose intolerance affects unequally in the world: only 5% in northern Europe, compared to 95% in Asians. In Spain, the figures are between 20 and 30%. Symptoms range from gases and abdominal pain to diarrhea. However, like Dietitian Julia Farré has clarified: “It is not usually a 100%intolerance: many people do not tolerate milk, but yes the yogurt or cured cheeses, which contain less lactose.” What if we don’t want to drink milk? Here the experts agree: it is not essential. According to Vogueit is possible to obtain calcium and green leafy vegetable proteins (kale, broccoli, spinach), legumes, spine fish (sardines, canned salmon), tofu enriched with calcium or fortified vegetable drinks. Yogurt and cheese, due to their lower lactose content, are usually better tolerated by those who have more sensitive digestions. Is it worth it? Science does not offer a unique response, but a consensus: milk is not essential, but it is not dangerous if consumed in moderation and individual tolerance. If we feel good, it can remain a practical, nutritious and culturally rooted food in our diet. If not, there are enough alternatives to meet the needs of calcium, proteins and vitamins without opening the tetrabrik. Perhaps, as experts remember, the true key is to listen to our own body. Because deep down, the question is not whether milk is good or bad, but if it is for each of us.

There is so much fever for the Xiaomi Yu7 that there are already those who pay more for buying one used than for a new one. And it makes sense

by

The fever by the Xiaomi Yu7 has reached its climax: it is already paid more for the electric SUV sold as a “used” than like a new car. The waiting list is so wide that the bubble has swollen to unsuspected limits. Not only is the mirror of an excessive demand. Used, yes, but more expensive. Specifically, about 2,400 euros. That is the area that those who aspire to have tomorrow (in China, of course) have to pay a Xiaomi Yu7 In the garage, according to Carnewschina. The specialized medium collects that there are up to 80 ads in vehicle sale stores where Xiaomi Yu7 is sold above the market price as new. Specifically, the profits is between 1,200 and 2,400 euros (depending on the version). The most coveted. Among the units that are sold, the most desired is the Max, which are generally offered with less than 100 km registered. Exit, The car had prices of 253,500 yuan (about 30,191 euros) for the Standard version, 279,900 yuan (33,335 euros) for the Pro version and 329,900 Yuanes (39,290 euros) for the MAX, the most powerful option. The more version has 101.7 kWh battery but it is not the option with greater autonomy. This is reserved for the Standard option which also has a huge battery (96.3 kWh capacity) but its power is lower, registering lower consumption. That, precisely, is the most attractive of the Xiaomi Yu7 Max, a car with an autonomy of 770 kilometers (according to the Optimistic Chinese homologation cycle) and a rapid power of 690 hp, an acceleration from 0 to 100 in 3.23 seconds and a maximum speed of 253 km/h. A business. That is, the most expensive option is registering overprices of about 2,400 euros. Or, what is the same, about 6% about its purchase price. It does not seem excessive but it is a pinch for those who made one of the company’s first reserves and want to do business or prefer the money to the car. But those who, of course, are doing business are concessionaires. They point in the Chinese environment to which a good part of the Xiaomi Yu7 overcrowded with respect to their output rate are concession automation. That is, these companies are playing with the usual margin and, right now, selling them more expensive than the company itself. Endless. The trend responds to the wide waiting list that Xiaomi faces when selling its cars. The fever for the electric SUV, the company’s second car, has led the brand to stop the reserves since the delivery of them has shot until 60 weeks in its Standard version. That is, about a year and two months. Pro and Max options offer better waiting times. But not much better. For the Xioami Yu7 Pro you have to wait between 49 and 52 weeks and for the Max between 39 and 42 weeks. That is, the delivery of the Xiaomi Yu7 Max has been almost 10 months. All this is a consequence of A wave of excessive reservations In the first hours. Before finishing the day of the presentation, Xiaomi registered 248,000 reservations in 18 hours. Of these, 200,000 were recorded alone In the first three minutes in which the page was open. Dragging the company. In Carnewschina They echoed another striking movement. The Xiaomi Su7 Yay had a really long waiting list but after relieving it slightly, the electric Berlina has re -delayed its delivery times. The company has decided to dedicate part of the current Berlin line to produce the electric SUV to try to balance the wait between both models. Again, the price of the Xiaomi Su7 was shot again in the second -hand market. To the point that the Su7 ultrathe most radical option rose up to 15,000 euros above of its rate price. Of course, there is no possible comparison with Yu7 because the latter has not yet announced a similar version. The risk. The greatest risk that Xiaomi faces is very evident: the tired of the client. China is the country where more electric cars are bought but also where competition is greater and The renewal time of the models is shorter. If Xiaomi fails to lighten the waiting list, it runs the risk of Your car is slightly obsolete In relation to the rest of the market and customers begin to flee to other brands. To solve it, the company works for forced marches to expand its factory for electric cars. For the moment It already has two factories dedicated (one to each product although, as we have seen, that of the Xiaomi Su7 is also giving way to some SUV units) And you have another in progresswith the aim of being able to serve a demand that has the company completely overwhelmed.

The Line goes regular, so Saudi Arabia has asked some consultants to solve the obvious: if it makes sense

by

When years ago The heir prince Mohammed Bin Salman presented the plans of The Linethe gigantic Pharaonic glazed city that Saudi Arabia wants to build in full desert, the idea sounded for science fiction. And it’s normal. Not every day a megalopolis of 170 km long, 200 m wide and huge skyscraper, all thought to welcome millions of people without roads or cars. Over time His works started And the project advanced slowly, between huge exiles and foundations concrete. Now its promoters have done Something peculiar: Ask several consultants for help to confirm whether the initial plans are viable or should adjust them. What happened? That Saudi Arabia wants to review its most pharaonic, surreal and delicate project: The Linethe gigantic “corridor city” of 170 kilometers and 500 meters high and 200 m wide that the country wants to lift in the desert. Although every so often its promoters They presume the advance of the works, Bloomberg He has just revealed that the Saudi authorities have commissioned several consulting companies to carry out a strategic review of the project. What have you asked? That value if the current plans are feasible and suggest possible changes. This is at least supported by Bloomberg, which quotes anonymous sources close to the project. They have not transcended more details or the consultants to which the Saudi Arabia Public Investment Fund has been directed (PIF), But the decision is interesting both for its background and for the context. Once you have the data, those responsible for the project must assess the information and choose: Do you need to apply changes? Can you follow the work without adjustments? Bloomberg clarifies that the plan could be kept as it is and that, if remembering, any change would demand the OK of the PIF and the Saudi executive himself. And what do promoters say? The Line is part of an even greater project, Neomwhich seeks to diversify the economy of the nation and includes other initiatives, such as Magna, Oxagon, Sindalah and Trojenaalthough The Line It is the most ambitious of all. Those responsible have removed iron on the fact that the PIF has taken advantage of external consultants and ensure that it is a normal procedure. “As usual in large plurianual projects, strategic reviews are a common practice and are carried out several times during a large development project or infrastructure program,” claims Neom. “The Line remains a strategic priority and Neom focuses on maintaining operational continuity, improving efficiency and accelerating progress to meet the vision and general objectives of the project.” Why does the context import? Because, like Remember the agencythe country dealt with the price drop of oil, a minor foreign investment than the foresee and budgetary deficits. Bloomberg Precise That to balance its budget Saudi Arabia needs Brent barrel to be 96 dollars, a figure that rises to 113 if the internal expense of the FIP is included in the projects of the heir prince. Both values are above around $ 71 current. Are you lowering your expectations? The news of the project review comes only a few months after the Saudi authorities Sale your expectations On the development of The Line. At least as regards the calendar. The initial objective was that in 2030 the Megaciudad welcomed 1.5 million residents, but now the promoters estimate that there will be only 300,000, according to Another filtration Published in April by Bloomberg. The size of the city in 2030 will also be far from the target of 170 kilometers. The finished surface would be just 2.4 km. Some sources They point out that the total cost of Neom, including The Line and other initiatives, would amount to about 1.5 billion dollars. Is it standing? Although their promoters have had to reduce initial optimism and want to escape other voices about planning, something seems clear: The Line will not stay in an ambitious model and a handful of colorful infographics. Although there is still work ahead, the works They have been advancing On the ground, something that Saudi Arabia has been responsible for making it clear Sharing From time to time images of excavators, operators and land movements. Three months ago Giles Pendleton, operations director, public On LinkedIn a series of Aerial photos in which the progress of what several Neom projects seems, including infrastructure of the future corridor city of 170 km. “Neom is real,” defends the manager. On the same dates the embassy of the Kingdom of Saudi Arabia in Spain also disclosed images Of the works in one of the tunnels that will circulate trains and load between The Line and Oxagon.

People have started rowing to touch their ass to the statue of the bear in Madrid. Makes as little sense as it seems

by

Recently Dublin’s City Council did something unusual: He put an escort To the statue of a woman to prevent tourists from groking her breasts. Before the Irish session had even thought about Raise the monumentdedicated to Molly Maloneto leave his generous bronze bust (discolored after years and years of touch) out of reach of the caresses of the visitors. Molly Malone’s is not a unique case. If you approach the door of the Sun, in the heart of Madrid, you can also check how the celebration Bear and madroño statue That decorates the square for almost 60 years has the innkeepers and a leg of gold color for the constant of tourists and neighbors. A two -colored bear. Few more emblematic places in Madrid than Puerta del Sol. And few more iconic points in the square (and the city in general) than the famous Bear and madroño statuea work by sculptor Antonio Navarro that decorates the area since January 1967, although since then it has already changed several times of location. If today you approach to see it, it is likely, however, two details that are relatively recent. To start it is likely to meet tourists queuing to take photos next to the Úrsido. If you look, you will also see that the animal is two colors. Most have a dark tone, but one of the legs and tail are somewhat clearer, almost golden. Actually both details are related. If the animal has “faded” it is largely because of the touch of visitors. @koda_009 If you are in Madrid or visit the city, you cannot go without touching the sculpture of the bear and the madroño at the Puerta del Sol. The monument is one of the most important symbols of the capital and, according to the belief, in addition to bringing luck, touching it also guarantees to return to the city. #Elosoyelmadroño #Madrid #Spain #Puertadelsol #Europe #Sabiasque? #Sabiasque #comunidaddeMadrid #SPain #for you #Solmadrid ♬ Original sound – Koda Is it a matter of good luck? The legend says to touch Malone’s breasts Bring good luckbut … why do people grocery the tail and the leg of the bear of the door of the Sun? Basically for the same. A quick search in networks reveals that there are people who believe What to reach the tail will bring you good luck and will help him return to Madrid. Other versions ensure that what you have to touch the bear is actually the heel or that the objective changes According to the origin Who is sovere to: If you are from Madrid you must go to the tail, if you are a visitor you have to touch the leg. A matter of superstition, as is the case with the statue of Malone or other sobbed sculptures, such as The porcellino from Florence, which also has the polished snout based on the handle of tourists, or The testicles of the famous Toro of Wall Street. There are even more rocambolescas legends, such as the one that argues that those women who deliver a flower, kiss and touch the penis of The Victor Noir statuein a cemetery in Paris, they will enjoy love and sex. THE KEY: IMITATION. Superstitions apart, the explanation of why people caresses sculptures is much simpler (and mundane). At least in the case of the Madrid bear. The key was given in 2023 Madrid_Secreto in Tiktok: people feel the impulse to play statues and over time that ends up leaving a mark on the surface of the monuments that attracts the attention of more and more people. Result: the habit grows and feeds up until it becomes tradition. The equation is completed with the best Selfiethe desire to return on vacation with iconic photos and the amplifier effect of the networks. @vanessaencinals Well I don’t reach but it’s my fourth time in Madrid 😂❤️ #fyp #Madrid #vacations #SPain #Osomadrileño #Granvia #Puertadelsol ♬ You can count on me. Amaia Montero. LODVG – Video Covers “I’ve seen it in Tiktok”. The million dollar question in the case of the Statue of Puerta del Sol is … who was the first to touch the sculpture? When did that derive in a tradition? And how has it expanded so fast? Recently eldiario.es He approached To the square to talk to tourists and even a guide and discovered several things. To begin with, the handle of the Úrsido seems to have started a few years ago, at least before the pandemic. The historian José Manuel Moreno, in fact, points out that “it is not a new fashion” and points out that there are other sculptures that are also a victim of the touch, such as The curious neighborlocated on the main street with Almudena. People touch their ass in search of the same: fortune. Another of the conclusions that are taken when talking to people who approach the statue to touch it is that, although the habit of the handle perhaps comes from years ago, it has expanded basically thanks to social networks. “I’ve seen it on Tiktok,” Recognize A young woman from Jaén. And the truth is that a quick search arrives for find A handful of videos in which people are seen playing sculpture and talking about their supposed effects to return to Madrid or have luck. Touch statues? That is the million dollar question. Is it okay to touch statues installed in public spaces, even to the point that your patina is affected? Should institutions avoid it? In the case of the Malone statue, the Dublinous authorities are clear, although it is true that in their case influenced that tourists focus (with jokes included) on the bust of the figure. “I don’t like it and put limits … wherever it can truly be a problem. But of course, it’s hard to define,” Moreno admits. In the specific case of Navarro’s sculpture, one of the factors that could have influenced the touching is The last reform of the environment, which banks … Read more

Method 90-90-1 is the new religion of hyperproductivity. It is only common sense with mystical numbers

by

The 90-90-1 method was popular by Robin Sharma, the author of books like ‘The monk who sold his Ferrari‘. Sharma is not holy of my devotion – its self -help literature sins of industrial optimism typical of the genre – but the formula of this method starts from something reasonable, and that made me look at it. The proposal is dedicate the first 90 minutes of every day for 90 consecutive days to a single objective. Something that, he says, will transform your life. This formula is the last incarnation of our cult of personal optimization, wrapped in the seductive promise that happiness is just three months away. The formula is elegant in its simplism. Researchers from the University of Nottingham discovered that The self -control is at its peak just after awakeningand then gradually exhausted during the day, something that explains my strong sports discipline at dawn and my desire for dusk. Sharma calls the first hours “Platinum time“And he suggests that they are the optimal time to work on what matters most. The method is based on circadian rhythms and the theory of human chronotypes: Each person has natural moments of greater energy that can be used strategically. The interesting thing of 90-90-1 is in what omits: it is a psychological trick disguised as a system, not a complete methodology of time management. Sharma himself warns: “There is so much available distraction that, if you are not very careful, it will dominate your days.” So The method works not by revolutionary, but for forcing a behavior that should be obvious: concentrate on the important when we have the most mental energy. But there is a trap: if we concentrate for an hour and a half it is difficult, it is a common place in productivity literature to start with shorter blocks, and increase them little by little. If the mornings do not work, adapt it to another moment of the day. If you interrupt you, have a plan B. The 90-90-1 can become Xyz and that each one adjusts it to their convenience. But when something is so flexible that it adapts to anything, it ceases to be a method. It is rather a sophisticated excuse to do what we already knew we should do. 90-90-1 is not useful for its magical numbers, but for its function as a ritual of initiation to disciplineblessed word often shunned that in fact is not verbalized in a method dedicated to it. Like any productive fashion, promises personal transformation in exchange for willpower to follow a formula. Life is rarely bent before such orderly formulas. The objectives change. Priorities change. And rigid systems are usually the first to collapse before real life. 90-90-1 does not go as much to optimize our time as the collective need that someone tells us when and how to work on what matters.

Google wants to replicate in its glasses with Android’s success in mobiles. Unlike Glass in 2013, now it makes sense

by

In 2013, Google Glass He promised to revolutionize our day to day with smart glasses that would give us real -time information. However, the project ran into multiple obstacles that led him to commercial failure. Now, more than a decade later, Google bets again on a similar proposal, but this time The cards on the table are completely different For two reasons: Android XR and Gemini. “If you go back and look at the original video of Google Glass’s launch, I think the vision was great. This idea of ​​a product that you can take and that gives you the right information at the right time was incredible. An interview during the Google I/O In Googleplex offices in Mountain View, California. The equation that was missing in Glass Image | Antonio Zugaldia The Google I/O. has left us with great novelties Around the company’s products and ecosystem. Almost overnight, Google bombard us with A flood of functions and products oriented to its Android ecosystem that Gemini has hugged strongly. Among some of the most prominent aspects we could try THE NEW AI MODE which replaces Google’s traditional searches with Search Live, Flow with the new Image 4 models and I see 3and even the new mixed reality devices with Android XR as Project Moohan and His glasses with Gemini. Payne has given us more context about the plans that the company has for the New ecosystem they are developing with Android XRwhich already borrows all the work behind android for mobiles. The Executive identifies three key elements that were not present at the time of Google Glass and that now exist: artificial intelligence, an ecosystem of robust applications and truly usable hardware. Image | Xataka “One thing that did not exist was the AI. Make Those experiences They were reality required some fundamental advances in artificial intelligence that had simply not occurred yet. Gemini is here now, “Payne explains. The second factor is the application ecosystem. While for Glass the developers had to build specific applications in a special development environment, Android XR takes a radically different approach. “We are building a platform. We work with the ecosystem. We include all Android developers. Now, instead that developers have to create a new application, the app simply works,” says Payne. Image | Xataka This approach means that All Android applications will work on Android XRfrom mobile phones to virtual reality glasses and devices, eliminating the input barrier that existed previously. With this, Google wants to leave behind That fragmentation problem That has been ballasting Android for years, offering universal compatibility, unified development tools and the use of open standards such as Webxr, Openxr and Vulkan to expand their ecosystem. Gemini as an intermediary between the software and us Interface that Google raises for Android XR in Project Moohan | Image: Google “We think Gemini is for XR what the touch screen was for smartphones,” says Payne, establishing a parallelism with The 2007 iPhone which changed the mobile industry forever. According to Payne during the interview, Google’s vision for his smart glasses is to create “a natural conversational interface that understands what is important for you and gives you the right information at the right time.” Glasses, equipped with cameras and microphones, They can feed Gemini with real world informationwhile the connection with the phone gives access to the user’s digital world. Real -time translation test with Gemini at glasses | Image: Google Glasses that people really want to wear The third pillar is hardware. Google has made significant investments in screens technology, such as The acquisition of Raxumwhich manufactures “tiny and efficient energy” monolithic micro LED screens, according to the manager. The company also seems to be considered as important Collaboration with brands Fashionable like Warby Parker and Gentle Monster to create “really elegant glasses, glasses that people really want to wear.” “What we learned is that people really need to feel that they wear normal glasses to wear them all the time,” Payne acknowledges about the lessons learned from Glass. And to see, the proposal that Google offered in 2013 with Glass cool a lot, but to win the mass public, perhaps opting for One more approach mainstream In design be more appropriate. Proof of this is the irrefutable success of the Ray-Ban Meta Not as a product, which also, but as a format. Privacy of what we know in Android PROJECT MOOHAN | Image: Xataka Aware of privacy concerns generated by a continuous recording device, Payne also told us more about the approach that Google is adopting in privacy and security. On the one hand, the idea is that the device offer key switches and markers To know when the user is recording, activating their location or sending their information to their servers. “Privacy ends up being the basis of anything we develop around the ecosystem,” says Payne. In the current prototype we cannot talk that these measures have been applied because they are not for sale to the public yet and everything indicates that the company still has a long journey ahead before marketing its glasses. Of course, Payne has been able to advance that The idea is to apply the Android already familiar permissions framework related to privacy, together with that series of switches and mechanisms incorporated into the hardware to protect the user. It is clear that having constantly connected glasses and that they see everything your eyes see must land with a crucial and determining approach in this aspect. The explosion with AI can be the ideal time to boost this technology As we have seen, for Android XR to stop being a niche and become a mainstream product, Payne identifies The confluence of three factors: abundant and useful applications, diversity of devices for different needs, and a powerful interface fed by AI. “No one is saying: ‘Do you know what I want to do? I want to wear a helmet. I want to wear smart glasses. I don’t know what they do, but … Read more

China responds to the US with 125%tariffs. It no longer makes sense to upload them more

by

The US has been significantly increasing tariffs on Chinese imports: rose from 20% to 54% April 2, then to 104% the April 8 and finally at 145% April 8. China has been responding. Rose from 10% to 34% April 4, then at 84% On April 9 and now he has just announced a last response, uploading the tariffs to US imports to 125%. And now what? China counterattacks. On Friday the Chinese Ministry of Economy advertisement The new tariffs with a striking message: at this point they already give equal future ups of tariffs by the US. “In view of the fact that there is no possibility of acceptance in the market for US goods exported to China with the current tariff level, China will not pay attention if the US part continues to impose tariffs on Chinese merchandise exported to the US in the future.” “A joke”. According to indicate In The Wall Street Journal, “although USA continued imposing higher tariffsit would not make sense from the economic point of view and would become a joke in the history of the world economy. “Indeed, with those tariff levels to producers no longer compensates for trying to sell their products in countries with these tariff levels. It makes no sense to upload them more. Zhiwei Zhang, president of the consultant Pinpoint Asset Management, indicated In CNBC that “this is the end of climbing in terms of bilateral tariff fees. Both China and the US have sent clear messages, and makes sense to upload tariffs beyond.” Talks? It does not seem that there is intention to initiate negotiations between the two countries, something that can cause colossal disruption in world supply chains. Even so, a spokesman for the Chinese Ministry of Commerce indicated In an additional statement that Beijing is open to negotiate with the United States on equal terms. The primary sector in danger. China exports more than it matters, but there is a sector that can be very punished by these tariffs, and that is the primary sector of American farmers and ranchers. That same segment is the one that has given many votes to Donald Trump in the elections. Soybean, a worrying example. The soybean industry is According to The New York Times one of the great affectedBecause China is the most important market for soybeans exported by the US. According to the US International Trade Commissionthe segment of “grain, seeds and fruits” represents an exports of $ 13,350 million, 11% of total exports to China. Above is just oil.

We lead all my life by measuring battery capacity in mobiles. Mah’s war makes no sense

by

How many more mah, better. We have been thinking about the specifications of a phone and, to a large extent, is something true. A greater capacity battery is usually a more capable battery with respect to a smaller. Despite this, there is a somewhat more complex unit of measure, but even more precise, traditionally used in the technical sheet of computers: Los watts-Hora (WHE). This is the most precise way to determine how long we can use our device, without leaving the capacity to your fate. We are going to explain, without delving too much into technicalities so as not to complicate your life, why we have been imprecisely measuring the battery capacity of our mobiles. Why do we measure in mah. The commercial standard for the phones battery is the Miliamperio Hora, a very useful measure for small devices with constant voltages. In addition, it is much more striking to indicate closed figures, such as 5,000mAh, than to tell that your mobile has a 19.4 Wh. However, its two main problems are, in the first place, when there is a voltage variation (you will soon understand why) this measure ceases to make sense. Although MAH is easy to understand, it does not provide an exact estimate of available energy, which can lead to incorrectly assume how long the battery will last in specific situations of use. Water measurement time. The watts -hora (WH) are the most precise unit to measure battery capacity, since they reflect the amount of energy available depending on voltage and current. He watt (w) It is the power unit, which indicates how much energy is consumed per unit of time. It is more useful to know how the battery will be used during the daily use of your mobile. The battery voltage is not constant: it is varying as its percentage of load and useful life changes. A battery, At the end of your useful lifeIt does not provide the same voltage as when it is new. In fact, if you have a modern car or motorcycle, you surely have access to real time voltage and you will see how you change as you use the vehicle. The mobile battery is lowercase compared to these, but also suffers small voltage variations. The ease of calculation. Even if the voltage was constant, the watts time would be an ideal measure. For example, if your mobile phone had a 5,000mAh battery and a typical voltage (the most common in phones) of about 3.85V, that battery would translate into 19.25 WH (capacity (MAH X Voltage / 1,000). Knowing the data, it would be enough to know the consumption in watts to deduce almost exactly how much the battery would last. In a concrete situation, as a very demanding game that leads to consume 6W constantly the division would be easy: 19.25 wh/6W = 3.2h. A data that stables: about three hours of screen with the mobile spending all rag This is why in segments such as computers, where consumption is crucial and marketing (something) less important, WHH is established as a standard to measure battery capacity.

For some reason, there are people trying crash against a wall. Makes more sense than it seems

by

A Tesla Model and, a wall that simulates a road, a youtuber of 65.8 million followers, its reputation. The reputation of Tesla, its security systems and semi -autonomous driving. Another YouTube. A cybertruck tesla. Another wall with another painted road. Indeed, there are people by throwing their tesla against a wall: what is happening? The coyote game and the roadrunner. “I am in my tesla at 64 km/h with the activated highway launched against a false wall in the style of the coyote and the roadrunner.” This is how it starts Mark Rober’s videoknown NASA engineer with a YouTube channel in which 65.8 million subscribers are counted. Rober travels in his car thrown against a false wall in which he has simulated that the road on which circulates continues and perfectly simulates what it really is: a decoration. The objective is to check if your Tesla Model and equipped exclusively with cameras offers better or worse performance than a car equipped with a Lidar system As far as autonomous driving systems are concerned. The background. Rober uses his video to explain the differences between a car that bases its semi -autonomous driving in the cameras exclusively and those that use the Lidar system. In 2021, Tesla already advanced that would base its entire system of driving aid in the cameras. In 2022 it was confirmed that the company would stop riding radars and sensors. The company ensures that its software is able to analyze everything that happens exclusively using cameras with reliability that matches that of radars and sensors. Along the way, evidently, the cost of assembling these components that irremediably increase the final cost of the vehicle is saved. To check if this is true, Rober tests A Tesla Moder and that only uses cameras In its Autopilot system and a lexus RX equipped with a lidar sensor of the luminar company. The cars are launched with activated semi -autonomous driving functions (Autopilot in the case of Tesla and adaptive cruise control in the lexus) to verify what happens in different scenarios. Among them, children who appear in the trajectory of the car or very intense rains. The wall. During his tests, the vehicle equipped with Lidar December and saved a child from being hit if he was already on the road, if he appeared behind an obstacle, in cases of fog and intense rain or if he was dazzled by an intense light. And yes, also if there was a wall on the road painted with the simulation of a road. The Tesla Model and could not say the same and the cameras did not exceed the tests of the fog, the rain … and the famous wall. In the latter case, the car was cheated and thought that the road continued, not stopping at all. And has exploded the controversy. The video Mark Rober has exploded the controversy on social networks for various reasons. The first and most obvious: does this type make sense? When can a car find a wall that completely covers a road simulating that it continues later? Beyond that this has to value each other, what is true is that Rober activates the highway a few seconds before reaching the wall and in the video it is observed how the system is disabled when it is going to collide. Rober has been accused of turning off the system but has defended himself on social networks publishing a complete video in which it is seen how the system is disabled before the crash. A criticism that has been repeated To Tesla vehicles, accusing the company of washing their hands before the authorities. But not only that, Rober has also been criticized for using a vehicle with autopilot and not with Full Self Driving (FSD)the most advanced autonomous driving system in Tesla while Lexus was equipped with Lidar, one of the most expensive technologies at the moment. Cameras vs lidar. The experiment has something interesting although not a resolution. The truth is that one might expect that a cameras based system is less effective than one accompanied by a lidar. The single combination of mounting a camera and a radar has been demonstrated The most effective option So far both day and night. The cameras analyze with images what they have in front but a lidar sends pulses of light constantly around them. That light bounces on the object and returns to the lidar. With the time that has passed since the shipping of the pulse of light until it receives it again you can create a 3D map that, in the case of the wall, serves to verify that there is an obstacle on the road even if it can deceive the camera. Autopilot and FSD. The other great criticism that has been made to Rober is that he uses a car equipped with Autopilot but not with the FSDthe most advanced driving aid system of Tesla. The FSD is offered as an additional option through a subscription and allows the driver to disregard driving (even in urban environments) as long as it remains attentive to what happens in front of his eyes. For example, the Autopilot demands from the driver the confirmation of lane change but the FSD navigates between the streets by itself, without the need for driver’s validations. In fact, in the United States it allows The car travels 65 meters without a driver Inside. Thus, we can ask a tesla parked to come to pick us up from a distance. And there are people by throwing their cars against a wall. Rober’s experiment has given wings to other YouTuber who have come out to defend the company. In response, Kyle Paul, who has 237,000 subscribers on his YouTube channel and specializes in Tesla videos, He has published his own test. The goal has been the same: will your Tesla Cybertruck before a wall that simulates the continuation of the road? And his answer is that if the car has … Read more
