“It is totally unnatural and we rest worse”

by

In 1902, engineer Willis Carrier invented air conditioning modern, but not so that we could sleep better or to combat heat waves: he created it to prevent paper from will be deformed by humidity at a Brooklyn print shop. More than a century later, that machine designed to save ink and paper has ended up regulating something much more delicate: our own sleep. Sleep with air conditioning. Every summer comes back the same question: Is it a good idea to sleep with air conditioning? And the answer is not as simple as it seems. The cardiologist José Abellán posed an idea that connects with something basic in our physiology: the human body is designed to sleep in an environment where the temperature drops naturally at night, not in one that is artificially frozen for hours. That’s the key. It is not that air conditioning is “bad” in itself, but that breaking that natural thermal pattern (going from daytime heat to constant and intense cold) can disturb rest more than we think. What the body asks for while we sleep. Sleep science has been confirming for years something very specific: To initiate and maintain deep sleep, your core body temperature has to drop slightly. This decrease is a biological signal to enter rest. That’s where air conditioning plays an ambiguous role. Used well, it helps facilitate that process. Misused, it exaggerates and distorts it. The difference is in moderation. Medical organizations and societies in Spain such as the Spanish Society of Pulmonology and Thoracic Surgery recommend temperatures between 22 and 24 degreesprecisely to accompany this physiological descent without forcing it. The problem is not getting cold, it’s overdoing it. Here is the most common mistake. Many people set the air to 18 or 19 degrees and keep it there all night. This can generate an immediate feeling of relief, but also dry mucous membranes, irritates the throat, congests the nose and can cause micro-awakenings that fragment sleep. This is what many people describe when they wake up with a dry mouth or a cold feeling. From SEPAR they insist Furthermore, air conditioning greatly dehumidifies the environment, and if the humidity falls too low, the natural defenses of the nose and throat become less effective against particles and microorganisms. What the organizations say. The health consensus in Spain does not say “do not sleep with air”, but rather “use it with common sense.” Moderate temperature between those 22 and 24 °Cavoid the direct jet to the body, maintain humidity between 35% and 60%, clean filters frequently and do not create extreme differences with the outside temperature. It is also recommended to use night mode or timer, so that the device slightly raises the temperature in the early morning. This fits with physiological logic: help the body fall asleep, but then let it follow its own thermal rhythm. The fan is your friend. The alternative that proposes Abellán makes sense within that logic: using air conditioning only to lower the initial temperature of the room and then switching to the fan. This cools the environment without continuing to dry it or artificially cool it all night. “Our body has evolved in a natural environment, and in nature it is normal for the temperature to drop a little at night, so what is totally unnatural, and makes us rest worse, is spending all day with the air conditioning on full blast and the temperature not dropping at night,” clarified. Other tricks he mentions, such as cooling wrists with cold water or lightly moistening sheets, work because they act on the body’s natural heat dissipation, not against it. They are small physiological shortcuts, not miracle substitutes. Conclusion: yes, but as a tool. Ultimately, the question should not be whether sleeping with air conditioning is good or bad, but rather how to use. If it is used to create a reasonable environment and then accompany the natural drop in temperature, can improve clearly the rest. On the contrary, if it becomes a kind of permanent night refrigerator, we are forcing an ecosystem that the body does not recognize as natural. And there it appears the modern paradox: We have the technology to sleep cooler, but sometimes we use it in just the way that makes us sleep (much) worse.

China already has a GPU that competes with Nvidia’s RTX 3060. The bad thing is that it arrives five years late and worse

by

The china crusade for achieving the complete independence in the field of semiconductors has taken a new step. The problem is that this step has not been as promising as we expected, and in fact it makes it clear that today the Asian giant is still far away of the semiconductor manufacturers that dominate the market. The alternative for gamers that promised. Lisuan Tech (砺算科技), a Chinese company dedicated to manufacturing semiconductors and solutions such as graphics cards for the end-user market, has launched its new GPU for the consumer market, the LX-7G100. The price and expectations. The official starting price is 3,299 yuan (about 420 euros at the exchange rate), and at that price the equivalent graphics card should be at least an RTX5060 Ti, which is usually below 400 euros. What we get in performance is far from that. Performance tests of the LX-7G100 typically fell well short of the RTX 3060.Source: NotebookCheck. Worse than the RTX 3060. The problem is that those who have had access to this graphics card and have evaluated their benefits They have realized that this manufacturer’s GPU is very far from that price/performance estimate. In fact, it usually competes more with the RTX 3060 of 2021, but even with it it loses: it offers approximately 65% of the performance from its rival NVIDIA. Good specifications. On paper, the LX-7G100 should offer more performance. It has a 7G106 GPU, 12 GB of GDDR6 memory and decent bandwidth, for example. However, it does not have truly mature support for DX12 and does not offer an alternative to Nvidia’s DSLL or AMD’s FSR. When used in modern games, performance plummets due to rendering glitches and code translation bottlenecks. Not even for AI. At Lisuan Tech they have also tried to bet on their ability to run local and private AI models. However, most of the development of AI projects is linked to Nvidia’s CUDA architecture. It is true that the Chinese company has its own compatibility layer to translate PyTorch and CUDA code to its native architecture, but the loss of efficiency is notable, which makes inference or local model training tasks become too slow compared to those allowed by Nvidia graphics. difficult to compete. Lisuan Technology announced the first milestones of this launch a year ago. The rumors they indicated that its G100 graphics processor is manufactured by SMIC with a 6nm photolithographic process that complies with US restrictions. An attempt was made to launch in 2023, but Lisuan had financial problems and a capital injection of $27.7 million managed to keep the project going. It remains to be seen if sales ultimately follow through, although certainly its price/performance ratio makes it attractive only to audiences like the Chinese, who may have more difficulties accessing models like the Nvidia RTX.

In Spain we could do worse

If you are one of those who At the end of the salary they still have a month leftyou have probably wondered at some point in which corner of the world your monthly salary would be enough to cover your basic needs. For that to happen, salaries They must be proportional to the cost of living in that country. This proportion is what defines whether employees in those countries have better or worse purchasing power. That is, if they can buy more or less things with their salaries. To facilitate the visualization of these salary data, the portal VisualCapitalist has created an illustrative graph that represents the salary data of different countries in the world collected by the International Labor Organization. In this way, at a glance we can get an idea of ​​which countries in the world earn more wages and in which of them the purchasing power of their employees is lower. Data adjusted for purchasing power parity Before beginning to explain these data, it is worth emphasizing that the data it provides In its report the ILO is data purchasing power adjusted (PPP). That means that do not directly reflect the real average salary in the local currency of each country that workers receive, but rather a corrected figure to be able to compare how much that money really means in different economies. This adjustment is necessary because the cost of living varies greatly between countries. A salary of 2,000 euros does not offer the same standard of living in Spain as in Switzerland, Luxembourg or the United States, where housing, food or transportation are usually much more expensive. The purchasing power parity try to correct that difference. Instead of just comparing how much a person earns, compare how many goods and services they can afford on that salary in each country. A simple example: if one person earns 2,000 euros in Spain and another the equivalent of 3,500 euros in Switzerland, on paper the Swiss salary seems much higher. However, since prices are also much higher in Switzerland, the real difference in purchasing power It can be quite minor. The PPP adjustment serves precisely to put both salaries on a comparable scale. Therefore, when the report shows PPP-adjusted salaries, what you are comparing is not so much the amount of salary you earn, but rather the real purchasing power between countries. That is to say, there is no point in having an apparently very high salary if the cost of living in that country is terribly expensive. In that case, the salary adjusted for purchasing power will be represented with a lower amount. In which countries the salary increases the most The graph leaves no room for doubt and Luxembourg leads the ranking where the salary yields the most with 9,307 dollars per month adjusted by PPP. Furthermore, it is the case that the Grand Duchy also has the highest minimum wage of Europe. Luxembourg surpasses Belgium in second place with $8,297 per month, and the Netherlands in third place with $7,234 as a parity-adjusted salary. Fourth place on the list corresponds to Austria with 6,832 dollars per month, followed by the United States and Finland, which are in fifth and sixth position respectively with salaries of just under 6,300 dollars per month each. Four of the top five positions are European, which shows that the old continent has economies that offer monthly salaries proportional to the cost of living. The countries where the salary yields less The surprise of the ranking is Switzerland with adjusted salaries of $4,683 per month adjusted by PPP. Although the Alpine country has some of the highest real wages in the worldis placed behind Canada or Italy after adjustment for local costs. That is to say, Swiss salaries are among the highest on the continent, but so are the prices of products, so purchasing capacity is reduced of its citizens. The high price of housing, services and consumer goods significantly reduces the real value of the Swiss salary. There is a large gap between the top positions on the list and the countries that are below the Top 10. For example, France is in twenty-fifth position with an adjusted salary of $3,064, which is a salary three times lower than its neighbor Luxembourg. The real average salary in France is around 3,650 euros per month, which leaves the PPP-adjusted salary slightly below. This indicates that the cost of living is slightly higher than the purchasing power of their salaries, so, overall, living in France is somewhat more expensive than living in Luxembourg. The same happens with Poland and Greece, which with adjusted salaries of 3,082 and 3,546 dollars respectively, close the list of countries in which it is most expensive to live for their workers. Spain’s wage stagnation With 5,166 dollars per month adjusted by PPP, Spain is located in the upper-middle zone of the table with just 56% of the purchasing power of the world leader. The case of Spain is the opposite of that presented in France and, on a smaller scale, follows in the footsteps of Luxembourg. The adjusted salary doubles the real average salary which, according to data from the Adecco Salary Monitor 2025is around 2,048 euros. This indicates that the salary in Spain allows the reference shopping basket to be assumed without major problems. That is, the purchasing power of employees in Spain allows them to make ends meet and leaves a certain margin for savings. However, the price of housing in Spain continues to be the main drag on purchasing power of the Spanish. For this reason, salaries in Spain have not climbed positions, despite the latest increases in the Minimum Interprofessional Wage that has moved the average salary upwards of the country.

In Japan there is no doubt that they live worse than 30 years ago. Houses are literally getting smaller.

by

The demographic crisis that drags Japan comes long. In 2024 we say that it is the great challenge of the nation, the same one that we could summarize with one fact: if we continue like this, By 2531 all its inhabitants will have the same last name. That’s why we have seen all kinds of ideas and proposalssome with more common sense than othersbut all with the idea of ​​raising birth rates and combating aging. Now there is another fact that aggravates the situation even more: the houses are smaller. The house shrinks. The data is official and comes from a study that is carried out every five years in the nation. The average housing space in Japan has reached its lowest level in 30 years, with an average of 90 square meters at the end of 2024three square meters less than the 2003 peak, according to the government study. The change reflects a trend towards reduction in the size of homes, evident in the last five years. Additionally, in both single-family homes and multi-family units, including rentals and condominiums. Multifamily, in particular, average only 50 square metersfive less than what the government considers adequate for two adults in urban areas. It’s the economy, friend. They counted on a report in Nikkei that the increase in construction costs, which has shot up 30% since 2015 in the country, is the main driver of this reduction of space in homes. To keep prices affordable and protect their profit margins, builders are downsizing homes, a practice known as “hidden price gouging.” Not only that. In addition, land prices in popular residential areas are also on the rise, which further aggravates the situation. This increase in prices has reduced the demand for larger, more expensive, personalized homes in favor of smaller, cheaper units. Impact on quality of life. It is another of the legs that slips from the problem. The reduction in living space creates discomfort, especially in small homes. For many people, like a 50-year-old woman who lives in a 30-square-meter apartment with her husband, the situation is described as suffocating. Even single-person homes, which They represent 38% of households according to the national censusare often considered too small for a comfortable lifestyle. And then there are young people, who face greater barriers to accessing larger homes, with prohibitive prices even on the second-hand market. Young people and birth rates. All this leads to what we indicated at the beginning. The reduced living space and the impossibility of purchasing larger homes discourage young couples from, for example, starting families, exacerbating the already worrying drop in the birth rate. Housing policies alone do not seem sufficient to reverse this trend, and experts such as Masayuki Takahashi emphasize that The key is to increase salaries in a sustained manner. During the period of high economic growth in Japan, rising wages allowed more people to access spacious housing, something that is not the case today. The elderly and housing. The housing problem goes much further. In fact, every time More seniors in Japan face difficulties renting housingeven if they have financial means. Cases like that of an 88-year-old man in Tokyo, who, with more than 100 million yen in savings after planning to sell his apartment, experienced multiple rejections for not being able to provide an emergency contact under 70 years of agea common requirement among homeowners in the nation. After four months of searching, he managed to find an apartment, but the case reflects a broader problem. Rent and the veto for older adults. According to 2020 census data, Japan had 6.7 million single-person households with residents aged 65 or older, accounting for 12% of the total. By 2030, it is estimated that this number will reach 8 million. Again, even though there are approximately 9.3 million of vacant homes, landlords’ reluctance to rent to seniors is a significant obstacle. In August 2025, the Ministry of Infrastructure published a survey specific about owners of the akiya which revealed that approximately 60% of these properties were inherited, with more than 70% built before 1980, and that more than 70% show signs of deterioration or damage. Reasons? 66% of landlords expressed reluctance to accept older tenants, in a ministry survey. The main fear: the risk of death of the tenant alone of which we have talked beforewhich can require costly cleanups and require reporting to future tenants for three years. This situation is worsened by the increasing loneliness of older people and the lack of close family members throughout the nation. Ultimately, and with official figures and data In hand, it does not seem that the housing problem in Japan has improved for three decades. In reality, and sticking to those numbers, houses are literally smaller and more expensive, both to buy and to rent. a problem that we see in many other nationswhere the practice of downsizing in homes to maintain competitive prices ends up affecting the stability of the real estate market and the residents’ own quality of lifewith special emphasis on the case of young people and the elderly.

The super Niño of 1877 wiped out 4% of the world’s population. The one that is already beginning to form promises to be worse, but what does that mean in 2027?

by

In the last week, El Niño has become suddenly real. Media like Washington Post, BBC or countless media in Spanish have begun to compare what is coming to us with El superNiño of 1877, the event that “wiped out 4% of the world’s population.” And, stated this way, it is no wonder; The story is simple: “a Child Godzilla is coming and no one knows if we are ready.” That is why it is important to know what exactly we are talking about and if, in short, “we are all going to die.” How serious is the matter? As we said a few days ago, between March and May the reliability of ENSO forecasts is usually worse than normal (because the equatorial Pacific anomalies go through their transition phase). That makes everyone go with “lead feet”; but the data is worrying. Ben Noll of the Washington Post broadcast on May 8 that the North American Multi-Model Ensemble projected “the strongest El Niño on record” between October 2026 and January 2027, with a peak of +3.1 °C in November. They are big words. Above all, because the ECMWF is along the same lines. In the words of Diego Restrepo, “El Niño is rapidly intensifying, and now 8 out of 10 models point to a super event and four project the strongest one on record.” And this looks like 1877? That is Noll’s thesis and it has been repeated a lot in recent days. However, the comparison is misleading. First, because, although the models are pointing to a historical ENSO, they are still models. That is, we still have no idea what is going to happen. And, to be strict, until the models recover their full potential in June, we will not know well. Second because, as argued by Kimberley Reid, from the University of Melbournethe intensity measured in the central Pacific does not translate linearly into impacts. Taking into account everything that has changed in this century and a half at a climate level, the impacts may be completely different. And thirdly because El Niño of 1877 was not the cause of that catastrophe. Yes, it is true that he set the conditions for it to occur but, as noted Mike Davis in “Late Victorian Holocausts”what killed throughout that quarter of a century were colonial policies. And what happened in 1877? A strange combination between a superNiño, the Indian Dipole and a tremendously warm North Atlantic between the years 1876–78 caused a global drought. The problem is that, in a world governed by imperialism, grain exports did not stop and, as local resilience mechanisms had been dismantled, a famine occurred that killed some 50 million people. But the consensus is clear: no matter how intense El Niño was, it caused the problem of its management. And that, although it may not seem like it, is good news. A few years ago the World Meteorological Organization (WMO) published a report with a clear warning: “climate-related disasters” have increased since the 1970s. Specifically, they have multiplied by five over the last five decades. According to their calculations, in the 1980s, 1,400 incidents were recorded – their tables include extreme weather, climate and water phenomena – and in the 1990s, just over 2,200. In the first decade of the 21st century, 3,500 were reached and during the last decade, which spans from 2010 to 2019, it was close to 3,200. Curiously, this increase in the number of disasters has coincided with a decrease in the number of victims. The WMO data is clearalso: from more than 50,000 deaths in the 1970s (incidents basically related to climate and water are taken into account) it went to less than 20,000 in 2010. From an average of 170 a day in the 70s and 80s, it dropped in the 90s to less than a hundred a day and to 40 at the beginning of the 21st century. What will happen? As Restrepo also points out“despite having more information and knowledge, today we have warmer oceans, much more vulnerable ecosystems and collapsing biodiversity. This could generate impacts on health and risks for food, water and energy security.” However, we are more prepared and more importantly we have time to prepare. The ball is in our court.

They say things get worse before they get better. The RAM crisis teaches us that they can always get worse

by

The current situation in which hyperscalers have made all the hardware manufacturers produce almost exclusively for them is leading us to a curious scenario. Apart from the huge RAM and SSD crisis that affects everything –and everyone– Changing from one technology to a newer one no longer depends so much on the needs of a company but on what is barely available on the market. AND The Elec points to a movement by Samsung that represents a new thrust for mobile phones, computers and everything that has soldered RAM. No more LPDDR4 modules. LPDDR4 LPDDR5. They stand for Low-Power Double Data Rate, the low-power version of the RAM tablets that we can buy when building a PC, for example. Unlike conventional RAM pickups, LPDDR memory is soldered to the boardachieving very high speeds with a minuscule energy cost. That is why it is the preferred one for smartphones, tablets and ultrabooks, but it is also ideal for some miniPCs that have become popular in recent months. The downside is that it cannot be expanded or replaced, but its features make it the only option for certain devices. The most powerful versions mount LPDDR5 and LPDDR5Xbut there are still many devices that have the fourth generation versions for cost savings reasons. The turn comes when, according to the South Korean media The Elec, Samsung has begun to cut off the supply of LPDDR4 and LPDDR4X modules to its customers. Translation. Although they are memories with a decade behind them, mid-range and entry-level mobile phones, as well as many other devices, continue to have these versions to keep prices low. At a time when the market is more volatile than evermaintaining those competitive prices by mounting memories that are still interesting in certain ranges was a strategy that made a lot of sense. However, as the media points out, Samsung seems to want to focus on the production of LPDDR5 and LPDDR5X memories. By converting the output lines of the LPDDR4 memories, they will be able to manufacture more new generation RAM, but the price to pay will be that mobile manufacturers will have to switch to that LPDDR5. Mid-range and entry-level smartphones will be faster, but also more expensive. The price to pay. A few weeks ago we already said that the impact was evident. memory represented 20% of the bill of manufacturing an entry-level mobile phone, being one of the most expensive components. And, at that time, the figure was expected to reach 40% by the middle of this year. With this reconversion of Samsung’s lines, we will see where the percentage increase is in a year in which it is already estimating a drop of more than 10% in mobile shipments. The calculations They are tremendous: In the entry range – increments of 30 dollars per unit. In the middle range – from 60 to 80 dollars per unit. In the premium – from 100 and 150 dollars per unit. Samsung itself is not spared. Here you can think that Samsung has a lever to eat the mobile market. That is to say, if it is one of the three that controls the memory production segment and, in addition, has its line of mobile phones and tablets, it can give preferential treatment to its ‘brothers’ to maintain the price in the midst of the crisis. Well no. They already commented that this was not going to happen and, furthermore, it is already flirting with the idea thats Galaxy A17 be an example of this movement. The company’s entry-level mobile has the Exynos 1330 SoC that supports both LPDDR4X and LPDDR5 memories. When the supply of LPDDR4X runs out, they will move to the new generation, which will mean that there will be two different A17s, one of them being one with 50% faster memory than the other. They go direct with HBM. But, as two pieces of news are better understood together, at the same time that the abandonment of the LPDDR4 production lines is pointed out, we have confirmation that Samsung is going to press ahead with the development of HBM memories. These are high-bandwidth memories that are packaged in AI training and inference platforms, and have been reported that Samsung has managed to reduce the HBM memory development cycle from two years to one. It’s a necessary boost to continue being both NVIDIA and AMD’s preferred choice for AI hyperscalers. Shortage. Putting all this together, the result is that there is a RAM crisis for a while. The bottleneck of the industry is enormous and that only three companies –SK Hynix, Micron and Samsung– are the ones who call the shots, and all have opted to satisfy the demands of AI, does not help the situation return to normal. Although there is Chinese companies that may have their opportunity In this scenario, the reality is that the estimate is that all the production of the large It will barely cover 60% of the memory demand until 2027. These companies, of course, are doing great. An example is that, in three months of 2026, Samsung earned more than in all of 2025. But for users and the consumer industry itself, the reality is different. And the worst thing is that there is no realistic date when we will start to see a recovery. NVIDIA has taken the lead, AMD tooand it is no longer just the US and China that need memory: Europe also wants its share of the pie. There are voices that They aim for 2028 as the year of recoverybut other forecasts they go above 2030. What is clear is that there is a crisis ahead In Xataka | TSMC’s only problem was that it was in Taiwan. So the United States has decided to get her out of there

everything that could go wrong went worse

by

In 2017, the technology company Plexcreator of the free streaming platform with his same namedecided to organize something that should be the event of the year for its employees: a whole week in Honduraswith a “Survivors” theme, to unite the company’s 120 remote workers. The budget that the company had allocated for that activity team building It wasn’t exactly modest: $500,000. The reality was, according to everyone who was there, something radically different. The experience was so “unique” that almost a decade later, the protagonists continue to tell it and even The Wall Street Journal has been echoed of that trip. And what they describe sounds more like a collective joke than a business trip. When chaos unites more than planning Corporate retreats have been gaining weight in human resources budgets for years, especially in companies with distributed teams to unite teams that do not see each other face to face throughout the year. According to IEBS data collected through the specialized portal Trafalgarpolo86% of companies that implement these corporate retreats report improvements in internal cohesion and talent retention, especially when your teams operate remotely. Plex is the perfect example: a streaming platform, whose employees work all over the world, that needed something to truly unite them. Something like a survival-themed experience, which in the end turned out to be more real than they would have liked. Keith Valory, CEO of Plex, acknowledged in the WSJ that the result was exactly what was expected despite the chaos: “You forge very strong bonds on these trips. It’s like the force that gives life to the company.” Almost a decade after that trip, many participants continue to work together and the adventures of Plexcon 2017 remain one of the team’s favorite topics of conversation. They even have a video of his adventure. Review by the CEO of Plex about his trip to Honduras The first signs that something was wrong on that trip came weeks before it began. Sean Hoff, founder of Moniker Partnersthe event’s organizing agency, told the WSJ that “about three weeks before arriving in Honduras, we received an email from the hotel’s general manager saying ‘I’m leaving. I wish you the best with your retirement.’ I knew something was wrong.” Three days later, another email: the head chef would no longer be at the hotel. Without a manager and without a chef, buses in Honduras began to fill with Plex employees. The adventure promises. The arrival did not reassure anyone. Scott Olechowski, product director and co-founder of Plex, said that they found the arrival disturbing: “Dirt roads. You approach and there are surveillance towers around the property and people with machine guns.” Many employees began to wonder where had they been taken. The first to fall was, precisely, the CEO who was supposed to lead the week with his team. Keith Valory disobeyed the unanimous advice of avoid raw vegetables and ate a salad. “I caught a E.coliwhich is the worst thing you can catch in your entire life. I lost between 8 and 10 kilos. The doctor came and they nailed an IV bag to the bedpost,” the manager told the American newspaper. Tarantulas, anthills and 38 degrees in the sun With the CEO prostrate, the tests with survivor theme They started under a blazing sun and at almost 38 degrees Celsius, led by an ex-Navy SEAL they had hired. In one of the tests, an employee had to eat a dead tarantula. He was from Texas and claimed to have eaten worse things. One of the survival tests consisted of eating spiders and insects In another test, another employee fell onto an anthill of fire antswhich forced give antihistamines urgently. There were no pills left, so they had to inject it directly into the affected buttocks. The infrastructure of the “luxury” complex didn’t help either. In the absence of the main chef (who had resigned weeks before the group’s arrival) the food came half cookedwater and electricity were cut off at any time of the day and the solar panelscovered by vegetation, could not charge the batteries and the premises were dark during the night. Sean Hoff, the person responsible for making everything go well on the trip, ended up with palpitations caused due to dehydration from running from one side of the complex to the other in high temperatures, trying to solve the problems that kept arising. “They had to call an ambulance and give me an EKG. They told me, ‘Sir, you need to slow down. You’re pushing your body to the limit.’” Stress tests for office workers devised by a special forces soldier One morning, a Plex employee found in his shower an animal similar to a porcupine which, apparently, had fallen from the ceiling during the night and became trapped in the screen. Stuck on an island with reggae and beer One of the nights they organized a dinner on one of the paradisiacal beaches on the premises. What should have been a pleasant evening with the sound of the sea as a soundtrack, ended with many attendees bitten by sand fleaswhich forced antihistamines to be distributed among employees. The next day, the group traveled to the neighboring island of Utila to visit the reconstruction of a baseball field that the company had financed. What no one had calculated was the return trip: the runway was very small and only allowed eight-seater planes. To make matters worse, it had no night lighting, so the planes could not operate at night. Despite hurrying as much as they could in the transfers, part of the group was trapped on the island without being able to return to the compound where they were staying until the sun rose again. One of the employees who was trapped wore out the antihistamines and had to notify a local doctor who improvised an intravenous line to administer it. Maybe karma wanted to wink at them, and the group that was stuck on the island spent the rest of … Read more

The Tax Agency does not want you to use ChatGPT for Income. The problem is that their alternatives are worse

by

The general director of the Tax Agency, Soledad Fernández, has opened the Income 2025 campaign with a clear message: do not use ChatGPT to make your declaration. “With how much the Tax Agency team has dedicated themselves to providing the best help and assistance tools, I wouldn’t risk doing it with ChatGPT,” he said. The warning has a certain meaning. The language models They can hallucinate, they do not have access to your real tax data, and asking them to manage your return involves passing them personal and financial information that ends up stored on private servers. The risk of error (and sanction) is real. That said, there are more nuances. Why is it important. The Treasury notice comes at a time when millions of Spaniards are looking for any shortcut to avoid one of the most tedious procedures of the year. If the official answer is “trust our tools”, the logical question is: are those tools really up to the task? Between the lines. What the Treasury does not say is that the underlying problem is not ChatGPT: it is that the Spanish tax system is opaque enough that using an AI seems like a reasonable solution. If millions of citizens are tempted to delegate their declaration to a chatbot, it is because something has failed before. The complexity of personal income tax (with its regional deductions, its cases of ascendants and descendants, its special regimes) is not an accident of design. It’s the design. The current situation. Treasury has presented improvements in Web Rental for this campaign: more access to data capture windows, greater interaction between sections and better information on subsidies. It has also improved its app. And it maintains the traditional channels: The plan “We call you“starts on May 6 (appointment from April 29). In-person attention in offices, from June 1. They are real advances, but gradual. Renta Web continues to be a platform that requires prior knowledge to navigate with ease. The Treasury virtual assistant resolves generic doubts, but not specific cases. Yes, but. The alternative that remains for those who do not master taxation is to pay a manager. A service that has a cost that not everyone can afford, and that turns a right (understanding and managing your own declaration) into something that must be outsourced. It’s the equivalent of IKEA selling its furniture without instructions and then complaining that people look up videos on YouTube to assemble it. The big question. The Tax Agency also assures that it does not use AI in the processing of files or in extensive control, and that its risk analysis systems “cannot be considered AI in the strict sense.” Although it leaves the door open for its future use. The question they do not answer is another: if AI is good enough for the Treasury to study it internally, why can’t it be part of a solution that helps the taxpayer from within the system, with their own data and with legal guarantees?

It’s science and that’s why they sleep worse than men

by

When sharing a bed with another person, there is a chance that there will be an eternal nighttime thermal war, with one person roasting in the heat and pulling the duvet down, while the other freezes and seeks refuge under the covers. For years, this has been treated as a simple couple anecdotebut the truth is that it has a physiological reason behind it. And something that has been seen is that women, statistically, sleep worse than men, with the thermostat being the culprit. Sleeping differently. To understand this phenomenon, we must first know how our body works when it prepares to rest. In this case, in order for us to fall asleep and enter the deeper phases, our core temperature must drop. However, during the REM phasethe body needs this temperature to rise slightly again. This is where the biological conflict comes in, as is exposed in the podcast Sleep is a Skillwhere a specialist explains how women generally tend to have less muscle mass and a lower basal metabolism than men. This translates into a skin temperature between 3 and 4 degrees colder, meaning that, with colder extremities, women prefer warmer environments to be able to reach that optimal temperature that induces sleep. Something that opens up many anecdotes, like how in a couple women need a sheet to sleep in in the summer. Their differences. In general terms (which is not universal), while men need the room and bed to be cold at the beginning of the night to lower their core temperature quickly, Women require a warmer environment to compensate for colder skin. and not suffer alterations in your sleep architecture. What science says. In the literature, there are multiple studies that confirm these gender differences in thermoregulation. One of these was published in 2023, where it was shown that women recorded higher skin temperatures than men during the sleep phase where there is higher quality. That is, it requires a warmer microenvironment to have a much more adequate sleep. Furthermore, several studies published in Journal of Sleep Research reveal that women reach nocturnal body temperature minimums earlier than men. But also, its temperature drops are less pronounced, which directly affects the quality of continuous sleep. The use of technology. Given this problem, there are companies that have set to work to do something that would a priori solve this problem for couples: use smart mattress covers to regulate the temperature on each side of the bed so that women sleep better. It is true that the data they rely on internally to sell their mattresses still has to be validated. Even so, the pre-existing scientific evidence is robust. Women are not “chilly” on a whim, but their biology requires a different thermal environment to be able to rest properly. Perhaps the definitive solution to disputes over the duvet is not by giving in, but by dividing air conditioning technology in the bed.

The Adamuz accident has plunged demand for the AVE by 30%. It is a fact that hides something worse: mistrust

by

The high-speed accident in Adamuz (Córdoba) has turned the Spanish railway upside down. Closures, speed restrictions and a loss of credibility in the service have directly impacted the sales of the three companies that operate on Spanish roads. And it has translated into data: a 30% drop in sales. The data. Demand for high-speed trains has fallen by 30%, according to data collected by Trainlinea railway ticket price comparator that operates in our country. The information was released by Pedro García, its general director in Europe and Spain, at an event organized by the company this week. According to this platform, the demand for banknotes has fallen by 30% in the weeks following the Adamuz accident (Córdoba) in which 46 people died after an Iryo derailed and, still under investigationthe subsequent crash and derailment of an Alvia that was traveling in the opposite direction. No trust. We could say that it hints at it but it is almost a cry: the customer is distrustful of high speed. It is not only a question of security, the drop in demand is undoubtedly influenced by speed restrictions that have been imposed and the cancellations late in the day between Madrid and Barcelona. It must be taken into account that, in just over a month, we have had the following schedule on the Spanish railway lines: Later. In the current state of high-speed lines, only one thing is clear: the train is going to arrive later. First of all, because Adif is reviewing all avenues and that requires, for example, In Madrid-Barcelona, ​​25 minutes have already been added by default to the journey. And that is in the best of cases. Because as reported by a train driver Xatakathose who drive the trains have the power to stop the train or move more slowly if they consider that the tracks are not safe or, at least, not at maximum speed. Their repeated complaints have led to temporary speed limitations that have been activated and deactivated but, ultimately, yours is the last word. This situation has been experienced with the reopening of the Madrid-Seville line. The driver, passing through the Adamuz section He stopped the train thinking that something was happening on the premises.. Then it turned out that, simply, confusion had arisen due to repairs carried out. to the plane. This distrust has caused a transfer of passengers to the plane. And the thing is that, especially companies, have been putting aside the use of the train for daily trips between Madrid and the large capitals of Spanish provinces. Especially in the Madrid-Barcelona route, where business use of the train was very high, demand for air travelers skyrocketed to the point that Iberia capped dynamic prices at 99 euros. The Ombudsman even asked the CNMC to study the price increases that were experienced in the following days in airlines and car rental companies. The rise in demand for aircraft between Madrid and Barcelona has been such that Vueling has returned to the Air Bridgea route that had abandoned in a movement where, without a doubt, The arrival of Ouigo and Iryo on Spanish roads had influenced. And an impact on the accounts. The combo of cancellations, high-speed restrictions and insecurity in arriving at the agreed time has caused a hole in the accounts of the large railway companies. According to theEconomistalready in January 2025 the losses were recorded at more than one million euros per day if only the cut in the southern corridor was taken into account. In The reason They raise the impact to a loss of 109 million euros in Malaga tourism alone. Losses that are yet to be quantified for companies but that arrive at a bad time, just when Ouigo and Iryo aspired to make money in our country after completing its landing phase. Photo | Samson Ng.
