trick

An electric car is 54% cheaper to maintain than a combustion car. And it may not compensate because the data has a trick

by

The cost of a car is not what you pay for it, it is the sum of many other factors. It is what it costs you to fill the tank, what it costs you to repair it and, why not, what you get back once you have decided to get rid of it. Are there reasons to go electric? Yes, many. Also to stay in the combustion. It depends on what you value. The data. An electric car saves up to 54% in maintenance compared to an equivalent gasoline car. Those are the accounts of Autobild that are spreading in recent days among the media. His comparison pointed to a Volkswagen ID.3 with a Volkswagen Golf VII 1.6 TDI from 2016 and a Volkswagen e-Golf, also from 2016. Why does an electric car have less autonomy than advertised? The result is that maintaining the electric car was between 40 and 54% cheaper than versions with combustion engines. According to their calculations, the revisions for the diesel version ranged from 393 euros to 547 euros. The plug-in hybrid had a price in its reviews of between 161 euros and 275 euros. The electric maintenance book required maintenance of between 200 and 300 euros. Of course, the stops were less frequent and, according to their calculations, as the kilometers passed, the pure electric was between 40 and 54% cheaper than its combustion “brothers.” Because? They give several reasons. First of all, as we have seen, because the reviews They are less expensive and less common. Fewer components have to be replaced in them, so it is necessary to invest less money. Among his accounts are oil changes (almost non-existent among electric cars), the total absence of possible breakdowns of a combustion engine and also the replacement of wear elements: timing belts, spark plugs, particle filter… In addition, they pointed out that some elements suffer less wear over the years and kilometers. For example, they predict a longer useful life for disc brakes because, especially in the city, most of the braking is absorbed by regenerative braking. and the day to day. There is another invariable fact: on a day-to-day basis, an electric car is almost always cheaper than a gasoline car. In the city, the electric car consumes less than a gasoline or diesel car. This, in addition, is exposed to a greater number of breakdowns with switching on and off every few kilometers. But if you want to do the math. An electric car in the city can easily move at 10-15 kWh/100 kilometers. That means that, with a domestic charge at 10 cents/kWhwe are talking about between one euro and one and a half euros per 100 kilometers. In the city, compared to a hybrid that consumes 4 liters/100 km we are talking about more than five euros difference per day. If it is a gasoline that moves at around 7 l/100 km in the urban environment, the difference goes up to nine euros. It is in long-distance getaways where the circumstances are equal. If an electric car consumes 18-20 kWh/100 km and refuels at 0.50 euros/kWh, we are talking about between 9 and 10 euros to travel 100 kilometers, figures very similar to gasoline. Charged in an ultra-fast plug at about 0.80 euros, we are talking about gasoline or diesel winning by a lot. Yes, but. That is to say, electric car is cheaper. Almost always, but not always. First, because that first comparison that has gone viral has something of a trick: the data is from 2021. The electricity figures posted above, for example, are current and less favorable to the electric car. However, as we have seen, those who use the car in the urban environment are very likely to find it worth opting for this technology. Of course, the latest data that are collected from ADAC (the German RACE) are not so optimistic. In that case they talk about a saving of between 20 and 30% in favor of the electric car. That is, they continue winning but the margin is narrowing. And if…? Calculating what one saves with an electric car is not entirely simple. For example, right now you can calculate how much money you would save in regulated parking areas in those cities where there are discounts on parking. And you can do the math thinking that the MOVES III Plan but, in some autonomous communities, this is not entirely safe. But not only that, when calculating what a car costs we can keep in mind its selling price, whether there is a premium for the electric version, the expected savings with our type of use and the kilometers to be traveled… but, What happens if we want to sell the car? In that case, the electric car seems to lose out. At this time, it is a technology that devalues ​​quickly because batteries degrade over time (range is reduced) and innovations are making cars obsolete in a very short time while new models reduce their prices. That is to say, the second-hand market has everything to continue losing money with the electric car. So what do I do? The first thing we recommend in Xataka is that you have very clear what kind of use you are going to make the vehicle. Be as rational as possible or, at least, be very clear about what you value above all else. If you like a passionate car and money doesn’t matter to youget the vehicle that you like the most. Here, however, we are here to talk about money. If you want a adjusted car, calculate the daily kilometers you travel, the types of outings you do and make calculations of the battery size you need. Of course, if a small car with 50-60 kWh capacity is enough, keep in mind that you will have to make concessions when you travel. In that case, only you set the price for your time. With all this in mind, do the following math: Cost … Read more

Chinese researchers believe they have discovered a simple “trick” to lose weight: eat raw vegetables

by

For decades, scientists have discussed the effects of vegan and ovo -vegetarian diets on weight loss and heart disease prevention. Without much success, really. Not because The clues in favor have not accumulatedbut because something was missing. A common link, a thread that organized all that scientific evidence and gave meaning. In recent years, a team of doctors from the Qilu Hospital of the University of Shandong He thinks he found That piece that was missing. And it’s an important piece. Above all, because obesity is becoming The great epidemic of the 21st century. 1.9 billion overweight peoplesome 600 million people with obesity and up. Something that would not be a problem if it wasn’t because, like They wrote Yani Xu and his team in their research, “obesity and its associated complications not only lead to an increase in morbidity and mortality, but also to a reduction in quality of life.” Finding simple weight loss strategies goes beyond aesthetics or fashion: it is an investment in quality of life. But did not solve Ozempic? It is true that the arrival of Ozempic (and the rest of New agonist medications from LPG-1) has radically changed our way of seeing overweight: as Antonio Ortiz said, these medications are helping us understand that Metabolism and appetite are biological facts, not moral elections. Biological facts that, as we see, bring huge social consequences. Plan b. Therefore, although the “new ozempics” are being revolutionary, they are far from being the solution to all our problems. Not only is these very expensive medications (and obesity shows a clear correlation with greater rates of poverty and precariousness economic); They are not substitutes for healthier and more balanced habits. That’s where Yani Xu and his team enter. In search of lost evidence. Tracking in the previous bibliography, Chinese researchers found 24 studies that followed more than 2,000 people. They were quite quality studies (randomized clinical trials) and that has allowed them to conclude that there was a detail that showed very strong links with a lower risk of obesity and heart problems: raw vegetables. In fact, this is true even when they eliminated the effect of genetic factors from the equation. Something not too common and, therefore, very interesting. “The vegetarian diet is a viable option for people who wish to control their body weight and (prevent) metabolic diseases,” They explain. How is it possible? The researchers They shuffle some ideas: From its high content of phytosterols and fatty fats to its role in reducing inflammation and oxidative stress. However, it is not too clear: we have a statistical explanation, but we still lack a mechanism of action. We may have solved one of the big problems when establishing a clear relationship between weight loss and veganism, but not at all. However, with the data that Let’s have on the tableit seems that the idea of ​​progressively increasing the weight of vegetables (and raw vegetables) seems like a positive strategy. More positive than we thought.

Wetaca doubles benefits thanks to the classic digital world trick: hooking to a subscription

by

602,000 euros of net profit in 2024, twice as much as the previous year. Wetaca has achieved what seemed impossible in the competitive world of food at home: grow in sales (23%) and improve margins at the same time, according to their 2024 accounts that he collects Five days. The turn. The company, founded by former Masterchef Efrén Álvarez consistent, has ceased to be a company that sells Tápers to become one that you subscribe. The automatic subscription model, launched in 2021generate weekly orders that are sent unless the client modifies or cancels them. You no longer have to remember to ask: the menus arrive alone. This apparently subtle change has changed the business. The recurrence has become the Holy Grail of Wetaca, which has invested more than 1.1 million euros in marketing to capture subscribers, twice as much as in 2023. In perspective. The prepared food sector lives a paradox: Dark Kitchens They left their best moment behind and the aggregators of Delivery They have a complicated profitability, but Wetaca is thriving with a model that seemed to have a difficult fit with the current offer. Centralized cuisine in Villaverde. Tápers that are sent cold. Menus that last a week in the fridge. Model that asks for a conscious and planned purchase, not impulsive. The difference is in the economic equation. Without RIDERS No commissions to platforms, without the pressure of delivering in half an hour. Only efficient production and customers that automatically repeat each week. And now what. With 94 employees and a debt of 5.2 million (1.5 in the short term), Wetaca will need subscriptions to continue flowing. The commitment to new machinery seeks precisely that: producing more maintaining the margins that have cost them so much to achieve. Between bambalins. The founders Álvarez and Casal maintain 71% of the company, while Cabiedes & Partners control almost 20%. This concentrated shareholding structure has allowed them to bet on the long term instead of pursuing growth at any price, the curse of so many delivery startups. The subscription model not only allows them to sell more: that model is a prediction machine demand, optimize production and reduce waste. When you know how many tápers you will cook every week, everything becomes more efficient.

Girona has managed to decongest its historic center copying a trick of Barcelona: erase from Google Maps

by

Girona has made Google and Waze modify the routes that took cars, especially tourists, to cross the old town of their city known as Barri Vell. This historical area has the Restricted circulationwith priority for pedestrians and limited access to residents and businesses. For Avoid excess traffic and preserve the pedestrian character of the center, the City Council asked the managers of those browsers to prioritize alternative tours and clearly mark the restrictions of access to the area. Atasque between 2,000 years of history Before, Google Maps and Waze guided To many drivers inside the Barri Vell to take shortcuts, especially tourists who trusted the GPS to move around the city. The problem is that, like most historical centers, this generated Unduse circulation in narrow and cobbled streets that are not designed for road traffic and hindered the circulation of neighbors. Such and as they highlight in The newspaper, In Barri Vell the circulation is restricted and special authorization is required to access even for distribution and service vehicles that are subjected to an access time control to prioritize the pedestrian use of the monumental center with more than 2,000 years of history. “We have been working to guarantee pacification at Barri Vell and the priority for pedestrians to be the seal of the city,” wrote Lluc Salellas, mayor of Girona In his X profile. Touch the photo to go to the original message The municipal idea for decongestion The Gironés City Council sent letters to Google and Waze to request that Barri Vell be eliminated as a recommended route to avoid the passage of tourist cars in this area. This management took several months, but finally was effective and GPS applications stopped proposing the historic center as a shortcut for the internal displacements of the city. In addition, the municipal team works so that the information shown in the browsers be as accurate as possibleclearly indicating the places where tourists They can park outside the historic center and preventing vehicles from being reserved where the spaces for loading and discharge are reserved. “We have made Google and Waze clearly mark that Barri Vell is an area with restricted circulation; and therefore, do not send tourists’ cars so easily,” explained Mayor Salellas to The newspaper.es. Girona is not the only one that has “erased” Google Girona It is not the only city that has asked Google to modify the information it gives to its users to redirect tourism flows and reorder the traffic of its streets. Barcelona City Council applied a similar measure To decongest the accesses to Park Güell, one of its most visited tourist places, eliminating from Google Maps one of the bus lines that went up to the park. This action sought to avoid the saturation of tourists and prioritize the service for the use of their neighbors, freeing them from the saturation of thousands of tourists who visit Gaudí’s work every day. In Holland, a small town managed to make fun of Google Maps To decongest its streets coordinating their neighbors to send false reports of cut streets. That caused the GPS to redirect traffic to alternative routes by freeing its neighbors from excess traffic. In all cases, this coordinated strategy with GPS applications has managed to reduce mass tourism in the most sensitive areas of cities, demonstrating how technological ones can influence tourist flows.

Polestar has broken a record of autonomy in electric cars circulating more than 900 kilometers. Obviously there is a trick

by

935.4 kilometers without recharging the battery. That is the record that has achieved a Polestar 3 conventional – in its version of a single engine – thus demonstrating that it is possible to make very long trips without going through a recharge point. The secret is from the record is obvious, yes. Superdespace. For achieve all those kilometers The technique was simple: go very slowly. In fact, the average speed was less than 40 km/h, and took no less than 22 hours and 57 minutes to complete the task. The publicized autonomy by Polestar for this model in its unique motor version is 706 km, so here they managed to lengthen it 32.5%. Three professional drivers. The tests were performed in the United Kingdom, where three drivers specialized in efficient driving were turned to achieve that milestone. The final consumption reached was 12.1 kWh per 100 km, which represents a saving of about 40% compared to conventional driving. Without tricks. This Polestar 3 achieved that autonomy without using special equipment: both the car and the wheels were the same as one obtains When you get the concessionaire car. However, it is possible to go further if some modifications are made. If you also have the car, you can go even further. A few days ago Chevrolet modified A WT Silverado truck and put a huge 205 kWh battery (the Polastar 3 is 111 kWh). They also placed old wheels with overpressure and 40 drivers turned to drive it around Detroit. They managed to travel 1,704 km with a single load, and as in the case of Polestar 3 the average speed did not exceed 40 km/h. The consumption on that journey was 12.7 kWh at 100 km, an equally remarkable figure in which yes, influenced that they had the air conditioning without working for almost the entire route. Baja is also worth it. In July a Lucid Air Grand Touring He got his particular Guinnes record When traveling 1,205 kilometers with a unique load. The car has a battery with the same capacity as that of the Polestar 3 (111 kWh), and toured the distance between St. Moritz and Munich. Although the car was a conventional model, the lucid benefited from both efficient driving and the energy regeneration system in braking and slopes: that route was full of them, but it was also descending mostly. The key is not the battery, they are the consumption. Although obviously the battery capacity influences the autonomy of electric cars, further influences the consumption of each model. The Mercedes Vision EQXX for example achieved a record prior to the Tour 1,010 km without recharging at 79.4 km/h on average… and another 392 kilometers had left in those conditions. The secret is that this approval model 7.4 kWh consumption at 100 km, while for example a tesla 3 rear -wheel drive homologous 13.2 kWh at 100 km. Aerodynamics helps, but if things are added to consumption as an efficient driving and low speed, those figures rise significantly. Absurd records. Although all these records are striking, they are also a marketing exercise for companies that logically try the same thing: that they talk (well) of them. Here we have messages that are also even absurd: going at 40 km/h for 23 hours has its reward in this case, but in real life it would be absolute torture. The practical uselessness of these records – not only that of Polestar – is the same as the one who tells us about how The Xiaomi Su7 beat all its competitors In Nürburgring last year: none of us are going to those speeds or drive in those circuits, but speed records are always striking. Putting these vehicles to the limit is fine, but it is important to contemplate these records with perspective.

The most obsessively competitive gamers have found a trick to win their rivals: Give Electric Downloads

by

Today video game developers are really strict in terms of cheating in their creations, with different systems Anti -che that They even affect kernel From our computer as is the case in ‘Valorant‘. But a new generation of Modders It is demonstrating that traps can be done without touching a single line of game code: with electrical discharges. If I can’t hack the game, I’m looking for alternatives. For some people, it is good for it is the same as Apply different tricks to games that they use daily to be able to cross walls, be immortal or have an automatic point when talking about Shooters. But this is something that leaves the rest of the players of a game. Having the player himself. Two Youtubers They have put the solution on the table to skip the barriers that are applied at the hardware level. One of them is ‘Basically Homeless’ that has led the concept of ‘player improvement’ to a new level. And instead of installing software that points for it in Counter-Strike 2, has created a system that electrocutes your arm to react at a superhuman speed. The mechanism is fascinating. An external software analyzes the screen in search of enemies. As soon as one detects one, it sends a signal to a Raspberry Piwhich in turn activates muscle stimulation diodes placed strategically in its forearm and hand. These little cramps force their muscles to get contracting, moving the mouse towards the target and clicking. Surprisingly, it is something that works. The results are very good. The own Youtuber He managed to reduce his reaction time of about 200 milliseconds approximately at only 100 milliseconds. According to its calculations, using an Ethernet cable connection instead of Wi -Fi to communicate the PC with the Raspberry Pi, it could lower this figure to 40 ms, a practically unbeatable speed for a human being. It does not consider it a trap. For this creator this is not something that threatens ethics when playing against other people. It is only a help, or as he calls it, ‘neuromuscular aim assistance’, since it is technically his own body who performs the action, although induced by a machine. Although it remains to be seen what large companies would say if this is popularized. Robotic carpets that point for you. In a similar line, the Modder Kamal Carter has presented another solution of hardware to dominate in Valorant. In his case, the protagonist is not his arm, but a robotic platform located under the mouse mat. And the system is similar. A screen reader identifies the enemy bots in the game’s shooting field in the first place. Next, a program that emulates the techniques of aimed at professional players sends instructions to the platform. This moves with a millimeter accuracy, displacing the mouse to achieve perfect shots. After adding a system that automates the click, Carter achieved almost perfect scores in practical mode. The most advanced anti-cheat systems are weak. “Made the law, made the trap,” says the saying. And in this case it is fulfilled. Large companies no longer know what to do to avoid tricks in their games, coming to ‘invade’ the kernel of our computer with maximum Windows privileges. Something that is designed to detect the use of unauthorized software. And there are many consequences that are being presented by cheating. Valve managed to block 40,000 cheats In ‘Dota 2’ or in ‘Deadlock’ They transformed into frogs to the most cheats to become aware that they should not do that. But also in Warzone they bet on Block the opening of the parachutes with the aim of crashing directly with the ground. But now these new tricks can be more difficult to detect and apply a punishment.

The most difficult thing to succeed with the arrow in Barcelona’s pebetero 92 was that it was not noticed that there was a trick

by

1992 was a year that will be remembered for many years in Spain. More than thirty years ago, but the economic and social footprint left Olympics of Barcelonathe Seville Expo And everything that surrounded both events still does not blur at all. Although we already know that “There was trick“Even in details as memorable as the flame arrow lighting the pebetero at the opening ceremony of the Olympics. What (we thought) happened. The torch entered the stadium in the hands of the largest Spanish medalist at that time, Palist Herminio Menéndez. Juan Antonio San Epifanio -EPI-, player of the Spanish Basketball Team, was in charge of taking it to the point where the Paralympic Arch Arch of Antonio Rebollo champion was waiting for him. The torch turned on an athlete’s arrow, which fired it through 86 meters from the stadium until it fell into the pebetero, lighting the Olympic flame between the clamor of the crowd of 50,000 people who crowded the stadium (plus 3.5 billion that watched him on television. What really happened. Rebollo faced A series of challenges that on television were not entirely clear. To start, the stadium was dark, so he had to take the dark shot, with the sole exception of a reflection indicated by the direction in which the Pebetero was. But the truth is that the arrow not only did the pebetero right, but should not do it: it had to pass a few meters away. The camera shot would make the rest, in a triquiñuela of perspectives that film directors know well and that makes it very complicated for the viewer to measure the distances. That is why there was an expert from the cinema. A film trick. To carry out the trick, there was Ábades Reyesveteran special effects designer and absolute reference of the sector in our cinema. He collaborated in more than 350 feature films, but it is in this event where he led to his most watched trick on a global scale. He won nine Goya awards and his are the effects of films such as ‘Oh, Carmela!’, It turns on yes or yes. Abades placed two of his collaborators outside the enclosure to pick up the arrow that would not have impacted the pebetero. Meanwhile, he would take care that the gas that came out of the pebetero became inflamed, something that would have happened in any case. That is, although Rebollo would have failed by many more meters than the planned and the perspective of the camera would have been useless, the flame would have turned on. Test and error. Of course, it was not the first time Rebollo shot the arrow. There were a series of essays in which Ábades could, for example, experiment with different materials for projectiles, and find one that would not go out during the flight. And they could also verify that it was not recommended that the date impact the alleged target, because it could spoil the gas outlet. A series of useless precautions because the illusion was simply perfect. Header | RTVE In Xataka | The three technological innovations that would change the history of the Olympic Games forever

Now we know Russia’s trick to multiply his drones. It is called “cooling units” and comes direct from China

by

If the question is how far Beijing’s help comes to Moscow with the Ukraine War in the background, the answer is very wide. We knew through documents obtained By Bloomberg that the production of Russian drones was being favored by the use of intermediary companies with China as main actor bound. Now we know something else. The engineering of deception to overcome sanctions. Clandestine flow. I told it in Exclusive Reuters. Apparently, Russia has managed to maintain and expand the production of its drones Kamikaze Garpiya-A1despite the sanctions imposed by the West, thanks to a sophisticated undercover import scheme that involves Chinese companies. Customs documents, internal contracts and invoices reviewed by the medium reveal that the L550E engines manufactured by the Chinese company Xiamen Limbach Aviation Engine Co. continue to arrive at the Russian state company IEMZ KUPOLnow through a Signature called Beijing Xichao International Technology and Trade. To avoid detection, engines are tagged as “Industrial cooling units” in transport documents, which has allowed Your shipment From Beijing to Moscow (and from there to Izhevsk, headquarters of the Kupol plant) without alerting Chinese customs authorities or formally infringing the country’s export legislation. Mass expansion. An internal Kupol document confirms that the company has signed a contract with the Russian Ministry of Defense to manufacture More than 6,000 Garpiya In 2025, tripling the production of the previous year. For April, more than 1,500 units had already been delivered. These drones, long -range and great precision, are regularly employed to Attack civil infrastructure and military deep in the Ukrainian territory. According to kyiv’s intelligence, Russia is using some 500 Garpiya per month. Based technologically on the Iranian Shahed, the Russian model has become a fundamental tool of Kremlin’s war effort, now enhanced by Chinese components that include not only the engine, but also Navigation and control systems. Ghost Companies Network. The path of engines to Russia is carefully disguised. After initial shipping from China, He had Reuters that engines are received by a Russian cover company called SMP-138owned by Abram Goldman, which in turn forwards them to another Russian company, Libss, final responsible for supplying Kupol. A contract between Libss and Kupol Reviewed by means Specifies specifically that the products should be identified as these “cooling equipment” to avoid suspicions. Chinese commercial companies Sichuan Airlines and China Southern Airlines have been used to transport these pieces Criticism of Russia since October 2023, despite the penalties in force. None of these airlines or the companies involved answered the Reuters questions. Ambiguous position. The Chinese Foreign Ministry, in response to the environment, He denied knowledge of these shipments and reiterated that the country strictly apply export controls of double -use goods, in addition to oppose sanctions Unilateral not endorsed by the UN. However, the reality of the continuous flow of military technology towards Russia calls into question that narrative. The Xiamen Limbach company was sanctioned in October of 2023, after an earlier Reuters report that already identified its role in the manufacture of the Garpiya, which caused new intermediaries such as Xichao They assumed the relief. In spite of these measures, or Xiamen or Xichao have given explanations, and the trail of responsibility is more than diffuse among layers of screen companies, documentary opacity and legally ambiguous trade routes. Diplomatic warnings. Plus: Revelation arrives at a time of Growing diplomatic tension Between the European Union and China. The president of the European Commission, Ursula von der Leyen, will meet with Xi Jinping and Li Qiang at a summit marked by Chinese support suspicions to Russian military machinery. European diplomacy, headed by Kaja Kallas, He has warned Beijing that allowing this type of trade puts the security of the continent at risk. China, meanwhile, insists that He has not exported Lethal weapons and that, if Russia uses its civil products for war, the same could be said of Ukraine. However, according to three senior European security officials, the case of Garpiya demonstrates that the Chinese supply It is not accidental or marginalbut part of a functional network that actively supports Kremlin’s military effort. European deterrence and strategic game. Experts Like Meia Nouwensof the International Institute for Strategic Studies, point out that China’s priority interest is to keep the United States focused on Ukraine, thus avoiding a direct confrontation in the Indo-Pacific. The implicit strategy would be to prolong the European conflict to gain margin of maneuver in Asia. For Brussels, however, the immediate priority is Cut the flow of critical components. Although the EU does not require China to break economic relations with Russia, it does insist that it reinforces its customs and financial controls to avoid the transit of sensitive products. For now, the proliferation of undercover engines and fictional companies shows that, on the Ukrainian battlefield, the China’s technological shadow is increasingly difficult to ignore.

The heat of the summer destroys the battery of your mobile. But there is a trick to give it a second life

by

It’s summer, I get home with a 20% of battery and the Telephone quite hot. I stop to see some videos in Tiktok and … I appreciate how the battery jumps directly from that 20% to 16%. What noses have just passed? Bulk. Your mobile has an internal microcontroller that uses estimation algorithms based on different variables. Voltage Temperature Current Load cycles As the battery is degraded, The system is losing precision: Errors in the calculations (something especially simple if we only make partial load cycles) accumulate, the loss of battery capacity is not exactly estimated, and this ends up translating into reading errors that directly affect the most visible point: the percentage indicated by the phone. How to know that if my battery is not well calibrated. It is quite easy to know if your mobile has or not the barefoot battery, since its behavior will be quite erratic. It goes out before reaching 0%, in upper percentages. There are notable battery jumps, more than 1%, both loading and downloading. The device never marks 100% or 1%. That a mobile has the bare battery It does not translate into a malfunction in the same: The error focuses on the visible reading that the user perceives, not on the performance of the battery itself. Why summer affects bruise. Telephone batteries have a great enemy: heat. There is no time of the year in which they suffer greater wear and are more likely to barefoot, precisely because of the acceleration of this damage they suffer. If we do not remedy it, it will be practically inevitable that we suffer sudden turns off for ignoring the exact battery percentage, and that the mobile stops to load efficiently when reaching certain percentages (fast from 20%, slow from 80%). How to calibrate a battery. Calibrate the battery It is nothing more than the process to help software to get precise readings about the real capacity of the battery. We seek to learn new vacuum points (0%) and full (100%), so the process is something drastic. Load the phone to the fullest and leave it, at least, a couple more hours loading. Download the phone completely and leave it a few hours without lighting. By battery protection, there is some reserve capacity after that 0% that is not lost until a few hours. Load the phone up to 100%, and leave it an additional time until the phone reaches the maximum load point. Avoid using applications that promise this purpose: none works. The only way to force calibration is to perform this process manually. Is it advisable to calibrate the battery? Evidence about calibrating the battery is still limited. There are those who aim to do them every three monthsbut if we do not observe anomalous behavior, stress the battery at this level may not be recommended. Calibration is necessary when readings are wrong and end up translating into a real problem to estimate how much battery we have left. The manufacturers are in full war to achieve batteries that there are many more cycles to go down to 80%below which the industry considers the replacement of it.

Some neuroscientists believe they have found the trick to solve the most complicated problems: take a nap

by

Surely, on some occasion you have obcended to find the solution to a certain problem and, no matter how much you insist on finding a solution, nothing, there is no form. However, another day, Without coming to mindZas! A brilliant and creative solution appears before you as a revelation. Congratulations, that’s a “Eureka moment“ No one knows exactly what mechanisms in the brain activate that spontaneous creative lighting momentalthough a group of neuroscientists of the Institute of Psychology of the University of Hamburg, believe they have found a culprit: the light sleep or N2, which is mainly reached to take a nap. But a brief, we know each other. N2 dream and creative connections A group of neuroscientific has published A study in the scientific journal PLOS BIOLOGY which points to sleeping one (or several) light naps during the day can be the key to unlocking creativity and the ability to solve difficult problems. This discovery not only attracts attention for its simplicity, but also values ​​a practice as healthy as it is nap. The study results suggest that, far from being a loss of time, sleeping a few minutes can activate certain mechanisms involved in the Creation of neuronal connections and in the processing of abstract concepts. To reach these conclusions, scientists recruited 90 young and healthy volunteers. Each one was assigned a seemingly simple task, but they were not revealed that there was a trick to solve it more easily, so they had to discover it for themselves. After four rounds of trials, the volunteers were invited to Sleep a 20 -minute nap while monitoring their brain activity with an electroencephalogram. The results showed that all groups improved their performance after nap, but the difference was notable depending on the sleep phase is achieved. 85.7% of those who reached the N2 phase of the sleep, that is, a light sleep state, managed to discover the solution to the problem. Instead, only 63.6% of those who stayed in phase N1 (a more superficial sleep level) achieved it. Only 55.5% of those who remained awake found the trick to solve the task. “Sleep EEG data showed that sleep N2, but not the N1, increases the probability of having mental lucidity after a nap, suggesting a specific role in the deepest sleep. We find a beneficial effect of sleep N2 in the Probability of having a vision after the napwhich suggests the need for a deeper dream to have a vision, “says the researchers in the study. “What really struck me by sharing these findings with my environment, especially with creative people, was the great impact they had. Many identified with our results and personally experienced a great advance (creative) after a nap,” assured to Newsweek Anika Löwe, one of the study authors. Limitations and nuances of the study Although the data is promising, the authors themselves warn that the method used does not allow precisely to be completed if the benefit observed is exclusively due to entering a certain Sleep stateto the simple rest, or other mental factors that occur during the pause. However, as indicated in their investigation, the results obtained only delimit an increase in the chances of getting a time Eureka after reaching a N2 sleep phase, but recognize that they cannot determine exactly the reason why this spontaneous inspiration occurs. “In summary, our findings suggest a role of sleep N2 in facilitation of inspiration, but more work is needed to determine precise mechanisms and to distinguish the effects of the dream of other factors such as disconnection of the task or rest,” which implies that there are still open questions about the exact mechanisms that facilitate these moments Eureka. Get away from the problem to find the solution Rest, approach change or simple fact of “take distance“The problem could be playing such an important role Like the dream itself In itself. Therefore, although phase N2 seems to be associated with a greater number of chances of having a eureka moment, it cannot be ruled out that other elements, such as mental relaxation or temporal disconnection of the task, they are also decisive. In statements to Eldiario.esPablo Barrecheguren expert neuroscientific In sleep, it emphasizes that the candidates were exposed to the evidence under a lack of sleep of 30% during the previous night, so “in addition, when performing only very short naps, the work also does not give information about what is the effect of leaving the subjects to sleep longer naps until reaching the deepest states of sleep.” Beyond the technical details and doubts about the neuronal mechanisms involved, the main message is clear and applicable to everyday life: if you face a complex problem and You can’t find the exitit is best to change activity, take distance and, if possible, sleep a brief nap. “It is often informed that inspiration occurs during periods of rest or sleep, when the mind is disconnected from the problem in question,” so the moments Eureka usually appear in the shower, When you try the dishes Or while driving. These are times when the brain is not consciously focused on the problem and can activate its abstraction capacity. This idea is not new. Geniuses like Thomas Edison or Salvador Dalí They already practiced The creative nap to stimulate its ingenuity by promoting the appearance of these moments of revelation. Friedrich August Kekulé, said he had deciphered the secret of the benzene chain After waking up a nap. Now, science begins to demonstrate that, indeed, sleeping a light nap can be The definitive trick to solve the most difficult challenges. If it doesn’t work, then what you take.
