We believed that procrastination was a time management problem. Neuroscience has shown that it is a survival instinct

by

Almost all of us have been in the situation of being faced with a task that must be done no matter what, such as studying an exam or handing in an assignment. We know that it is something important, and that we should start addressing it now, but suddenly we are doing something totally different and insignificant like reorganizing the drawer or watching a video on YouTube. What seems so common is what we call procrastinationand we understand more and more why we do it. The context. For decades, popular culture has told us that procrastination is a time management problem or, worse yet, simple laziness. However, neuroscience has a very different message when it points out that procrastination It is not an organizational failure, it is a crisis of emotional regulation. The brain. To understand procrastination, we must first look at the anatomy of our brain, which often functions as a large battlefield divided into two sides. On the one hand we have the limbic system, which is one of the most primitive parts of the brain and whose function is simply to keep us alive, away from pain and seeking immediate pleasure. On the other hand, we have the prefrontal cortex, which is the most evolutionarily ‘modern’ area, located right on the forehead. This is where we have rational thinking, long-term planning and logic. What is known. Already a 2021 review pointed out that these areas are activated when you have to do a task that generates anxiety, boredom or insecurity, such as studying an exam. And it is no wonder, because the limbic system detects this situation as a “threat”, and automatically hijacks the prefrontal cortex to prioritize immediate emotional relief by looking at Instagram over the long-term benefit of starting to study to pass. We know more. Now, this year, a new study has taken a new step to understand this brain system, by identifying in primates a specific neuronal circuit that functions as a “brake” for motivation, and that connects two parts of the brain: the ventral striatum (VS) with the ventral pallidum (VP). The researchers discovered that when we face tasks associated with discomfort or the possibility of failure, this VS-VP circuit is activated, inhibiting the action, as if it were an emotional protection mechanism taken to the extreme. The most striking thing about the study is that, by interrupting this circuit in the laboratory, the subjects immediately restored their motivation, “releasing the brake” and tackling the difficult task. It’s not laziness. This new line of research is consistent with previous research that associated procrastination with stress, fear of failure, and anxiety. In this way, when seeing a blank document or a very complex Excel sheet, the amygdala activates a flight response. In fact, it has been seen that chronic procrastinators tend to have worse connectivity between the amygdala. the anterior cingulate cortex, which makes them less able to filter negative emotions and distractions. In short, the brain will procrastinate to protect itself from the psychological discomfort caused by a task. Hacking. Seeing how complex this all is, blaming yourself or calling yourself “lazy” is of no use. But it is true that you have to follow a strategy to be able to hack our perception of stress and reward, starting to break up the work, making it so that, instead of setting out to “write the entire work”, you should opt for “write only the title and the first paragraph for five minutes” to trick the amygdala. It is also possible to block sources of easy dopamine with a blocking system on your computer or mobile phone that makes it difficult to access Instagram or YouTube to watch a video. This way, if the immediate reward requires an effort like going to the next room for the phone, the prefrontal cortex has time to intervene and put us in concentration mode.

His biggest problem is not money, but balance

Spending a vacation on board a cruise ship is a tourist option increasingly in demand even by travelers high purchasing power. However, Mario Salcedo, a millionaire who made his fortune in finance, decided 26 years ago to turn his daily life into a vacation. Since then, he has been linking cruise trips turning these giants of the sea in your home. However, this life of luxury aboard some of the largest pleasure ships has taken its toll on him: he has lost “his land legs” and is no longer able to walk in a straight line when he arrives in port. Always live on vacation. The millionaire of Cuban origin counted in 2019 to The New York Times He was never interested in starting a family, so his life on land only consisted of working and working. So one day he decided to leave his apartment in Miami behind and embark on a cruise. The experience impacted him so much that since then he has been combining one cruise with another and now his house has several decks, swimming pools, dance floors and some fleeting neighbors with whom he socializes whenever he can. After being a regular among the passage of the Royal Caribbean companythe crew already knows him as Super Mario. “I don’t have vacations. People come here to spend vacations. Not me, I’m here to live my life,” explains the millionaire. Life on board. The millionaire investor uses a reserved table on one of the cruise ship’s decks where a handwritten sign reads “Super Mario Office.” Obviously They do not refer to the Nintendo characterif not to the place from which the millionaire sits every day for a few hours in front of his laptop to telework. In this way he has paid for the more than 1,154 cruises he has completed in his life on the high seas. The millionaire claims to dedicate between 70,000 and 100,000 dollars a year for his travels. The millionaire counted on an interview for Condé Nast magazine, who booked an inside cabin without a balcony, because “I don’t do anything in my cabin except shower, get dressed and sleep,” he explained. The rest of the day he could be found in his “office”, socializing with other travelers or dancing in one of the ship’s dance rooms. To avoid having to constantly change cabins, Salcedo plans it 150 reservations in advance, linking one voyage to another. The worst thing about living on a cruise ship is getting to port. Everything would indicate that the biggest cost of living on a cruise ship is money. However, for “Super Mario” the greatest sacrifice is going ashore. After more than 25 years rocked by the sway of the waves on the best cruises, the millionaire has developed a rare disease called landing disease. This is a rare disorder that affects the vestibular system of the ear which affects balance giving a constant sensation of movement even when you are stable and motionless on dry land. It is popularly known as “earth legs.” Usually, this is a disorder that lasts at most for a couple of days, but when your life takes place on the high seas, and you only spend a total of fifteen days a year on land, the disease becomes chronic. “I have lost my land legs. I sway so much that I can’t walk in a straight line. I am so used to being on boats that I feel more comfortable than on land,” he said in his interview. Doesn’t usually go ashore. There is no doubt that Mario Salcedo is like a fish in water on board a cruise, so the few times he goes ashore he does so to take a plane to take him to his next cruise, when they dock in Miami to check that everything is still in order in his apartment or when he has to make arrangements with the bank or medical visits. Luckily, except for his problem with balance when he steps on dry land, the millionaire in his sixties is in good health. A key factor for “Super Mario” to continue his adventure on the high seas, given that shipping companies prohibit that a person who requires constant medical care comes on board.

China prepares a 2nm AI chip to end NVIDIA’s dominance. Your problem is how you are going to manufacture it

by

A new chip designer for artificial intelligence (IA) is preparing to take the field in China. And he intends to make a lot of noise. In fact, it is already doing so. It’s called Dishan Technology, and, according to SCMP, is already verifying the prototype of a 2nm AI GPU that uses a hybrid integration technology that combines FinFET and GAA transistors (Gate-All-Around). However, this is not the only thing that has emerged. According to Dishan Technology, this chip will be 40% more energy efficient than its predecessor and will be compatible with CUDA (Compute Unified Device Architecture), from NVIDIA. This latest technology brings together the compiler and development tools used by programmers to develop their software for NVIDIA GPUs, so if Dishan’s chip is really compatible it will be much easier to integrate it into facilities that already have GPUs from this American company. Although, as I mentioned above, Dishan already has a prototype of its chip, it will take another year or two to refine its technology enough to make large-scale manufacturing possible. Be that as it may, what has not been revealed is who is going to manufacture it. SMICthe largest Chinese semiconductor producer, can currently only manufacture 7nm chips using the multiple patterning. And TSMC, Intel and Samsung, which could produce it, will hardly do so in the current geopolitical context due to the demands of the US sanctions on China. We will see how Dishan Technology solves this challenge. China already has three “champions” in its AI chip ecosystem The country led by Xi Jinping you already have three alternatives very clear to NVIDIA. Although not as well-known as Huawei or Moore Threads, Cambricon Technologies is one of the companies specialized in designing GPUs for AI with the greatest growth potential. In fact, in August 2025 it received approval from the Shanghai Stock Exchange (China) to raise $560 million. He is allocating them to the design of four chips for training and inference of AI models, and also to the development of an alternative to CUDA. Moore Threads has developed several GPUs that rival advanced solutions from NVIDIA, AMD or Huawei On the other hand, Moore Threads has developed several GPUs for AI applications that, on paper, rival some of the advanced solutions that NVIDIA, AMD or Huawei have placed on the market. The cards MTT S4000 and MTT S3000 They are its most interesting proposals right now, although, curiously, the MTT S80 card also appears in its portfolio, a proposal for games and content creation that, according to Moore Threads itself, has a computing capacity of 14.4 TFLOPS in single-precision floating point operations. The other indispensable player in the Chinese AI chip industry is Huawei. His most ambitious proposal right now is the chip Ascend 950PRwhich aims to surpass the performance of the GPU NVIDIA H100. However, this Chinese company also launched its chips last year Ascend 910D and 920. This last solution is clearly intended to compete in the Chinese market with NVIDIA’s H20 GPU. Presumably at the end of 2026 it will launch its Ascend 950DT chip, and the Ascend 960 and 970 GPUs will arrive in 2027 and 2028 respectively.

Samsung faces a very serious problem to surpass TSMC with its 2nm chips: the 60% curse

by

When semiconductor manufacturers produce a chip wafer, some of those cores do not function properly. It’s normal. When they start a new lithographic node your performance per wafer usually has a wide room for improvementbut little by little, as engineers refine their integration processes, this parameter improves. A mature lithography can deliver very high performance to IC manufacturers, but a nascent technology can move in the orbit of 50% performance. Importantly, chipmakers need the per-wafer yield to be at least 60% to ensure node profitability and attract more customers. However, this figure is the minimum admissible. And in reality it must be much higher to optimize the competitiveness of photolithography from a commercial point of view. Currently TSMC and Samsung are manufacturing 2nm chipsbut according to the leaks the performance per wafer of its nodes is very different. And the South Korean company needs its 2nm node to be a success. The 1 and 2 nm nodes are crucial in the itinerary that Samsung has planned This reflection that Han Jong-hee, co-CEO of Samsung, made in mid-2025 express clearly At what point were you then? the largest company in South Korea: “First of all, I sincerely apologize that our stock performance has not met your expectations. Over the past year, our company has not responded appropriately to the rapidly evolving AI semiconductor market.” These words were addressed to his investors. Samsung needs to make its current best chip manufacturing technology a success A very important idea emerges from Jong-hee’s words: the competitiveness of your subsidiary specialized in the manufacturing of integrated circuits is essential for Samsung. Even so, problems were arising from several fronts. “Our technological advantage has been compromised in all of our businesses. It is difficult to see that efforts are being made to drive great innovations or take on new challenges. There are only attempts to maintain the status quo instead of generating disruptive changes,” said an internal statement written by Jay Y. Lee, the company’s president. In this scenario, Samsung needs its current best chip manufacturing technology, 2nm lithography, to be a success. And it’s in it. Integrated circuit producers do not typically make the per-wafer yield of their cutting-edge lithographs public, especially if it is relatively low. However, according to DigiTimes Asia Currently the performance of its 2nm nodes oscillates around 55%, so it is below the 60% threshold that we talked about a few lines above. For this company, it is essential to increase the yield per wafer of its 2nm lithography because with a yield of 55% the percentage of usable chips after advanced packaging probably ranges around 40%. To curl the curl, again according to DigiTimes Asiathe per-wafer performance of TSMC’s 2nm nodes ranges between 60 and 70%which places this Taiwanese company, which is Samsung’s biggest competitor and the leader of the chip manufacturing industryin a very favorable position when it comes to attracting new clients. If Samsung manages to raise the performance of its 2nm nodes above 60% during the coming months, it will put up a fight against TSMC. Otherwise you will suffer.

We believed that tons of feces were the big problem with the touristification of Everest. Until the scam rescue arrived

by

Everest may be the roof of the world, but it has long ceased to be the remote and isolated place they found themselves seven decades ago. Edmund Hollary and Tenzing Norgaythe first to summit its icy summit. The best proof was left to us just before the pandemic by Nirmal Purja, the author of one of the most famous (and striking) snapshots of the mountain: in it we see a very long row with dozens and dozens of tourists climbing in single file towards the summit, just as if they were queuing to enter the Louvre or board a cruise ship. That Everest has become a monster touristified It’s no surprise. What is curious is that there are people (presumably) breaking the laws to take advantage of that demand and defraud the insurers. A huge theme park. One would expect the highest place on the planet to be an inhospitable place, reserved for the most intrepid locals and adventurers. Perhaps it was like this in the 1950s, when Hollary and Norgay ascended to more than 8,800 meters of altitude to reach its summit. Not today. The photography that Purja took in 2019 is just the graphic verification of a phenomenon that can be measured in figures… and even in feces: Everest is a tourist icon that they visit every year hundreds and hundreds of climbers, leaving behind millions of dollars and a trail of tons of waste. You will find more infographics at Statista Where there is tourism… There is business, of course. That universal truth is applicable both in Amsterdam, Florence either Barcelona such as in the remote Himalayas, which over the last few decades has seen a thriving industry take shape dedicated to serving those who visit Everest. According to the World Travel and Tourism Council (WTC), in 2023 alone Nepal’s tourism sector generated revenue worth about 2.5 billion of dollars and boosted hundreds of thousands of jobs, both direct and indirect. Even Nepal has considered shoot 40% the fees he charges mountaineers, a source of income that among other things helps him clean the region. Where is the problem? Beyond the environmental impact that this overcrowding has in the mountain range, there is actually no problem in travel agencies, Sherpas, transportation companies, hotels and other businesses oriented to Nepalese tourism trying to make money. Climbing Everest doesn’t come cheap, but at the end of the day, whoever wants to pay for it. The problem is that not all of these professionals respect the law when looking for ways to make money. What’s more, there are those who have no qualms about cheatfalsify and commit millionaire frauds. Mountaineering and picaresque. The news I advanced it a few days ago The Kathmandu Postone of the largest English-language newspapers in Nepal. The Central Investigation Bureau of the Nepalese Police (CIB) has revealed a network dedicated to deceiving insurers who cover mountaineers in the Himalayas. Their modus operandi may vary, but the idea is always the same: alleged scammers make fraudulent ransoms to claim compensation. It may sound rudimentary, but the scam takes advantage of two circumstances that work in its favor. First, in rescue operations speed prevails, so there is no room to wait for the approval of the experts. Second, deceived insurers are often based thousands of kilometers away (in London or Paris), making it difficult for them to confirm what is happening on the ground. One goal, two methods. How do you prepare the scam? The CIB has identified two methods. The first is quite simple and requires the tourist to participate in the deception. If a climber is exhausted after days (or even weeks) of hiking and wants to save the trip back to camp, his guide can offer him a way out that is as comfortable as it is ethically questionable: faking an illness so that the insurance company can mobilize a rescue operation. The second method is a little more complicated, but the end result is the same. The guides or accommodations take advantage of the client’s ignorance to make them believe that the symptoms of altitude sickness (which are usually resolved with rest, hydration and a gradual descent) are actually signs that they are at serious risk, even of death. The key is to suggest the hiker enough so that he ends up asking to be evacuated by a charter helicopter. And where is the business? In the cost of the operation. It is not just that the company that provides that service charges the insurer for a helicopter that was not really necessary, it is that, precise The Kathmandu Postoften manages to expand its profit margin. As? It carries several passengers on the same flight and then sends separate invoices to their insurance companies. In practice that means that a single $4,000 charter flight can end up giving rise to three separate claims worth $12,000. Added to this are alleged treatments in the hospital, even when the client in question did not need assistance. For example, the Nepalese newspaper talks about cases in which treatment is claimed for hikers who were actually in the cafeteria. Not all people who are involved in this mess have to participate in the deception. He post speaks of falsifications of flight manifests or reports with digital signatures of completely unrelated doctors. One figure: 20 million dollars. At the end of March the CIB accused 32 people for this type of crimes, which according to the AFP agency amounted to a total scam 19.69 million of dollars. It may seem like a lot, but the figures revealed by the CIB investigation are eloquent: between 2022 and 2025, it identified 4,782 foreign patients treated in the investigated hospitals. Of these, inspectors believe that 171 corresponded to simulated evacuations. During that period some health centers received deposits worth millions of dollars related to those services. The older ones are the helicopters. Poisoning? The CIB investigation has attracted the attention of the media everyonealthough their headlines often focus on another … Read more

Prepared food already represents a business of 3,000 million for Mercadona. And that is a problem for McDonald’s and Burger King

by

The proverb says that a picture is worth a thousand words. The success of the so-called ‘merchants’ Supermarkets that are hybridizing to become places where you can buy and consume already cooked dishes are not only measured in images and words. It can also be followed with something much more forceful: figures. One of the most resounding he just left her Mercadona. Throughout 2025, the Valencian chain had a turnover of around 700 million euros in Spain through its section ‘Ready to eat’. If we expand the focus to include its pre-cooked offering (refrigerated, trays…) the joint business volume in Spain and Portugal amounts to 3,000 million euros. What has happened? We have just obtained data that helps us better understand how the ‘Ready to Eat’ section is working for Mercadona. According to the information advanced by Food RetailIn 2025, the Valencian chain invoiced 700 million euros in Spain through this channel. Perhaps it seems like a discreet figure when compared to its global sales, which were close to 39.8 billion in Spain, but it is interesting for two big reasons. First, because the ‘Ready to Eat’ section is young. It was not launched until 2018. Since then Mercadona has been expanding it throughout its network (in 2025 it reached 210 new supermarkets) until it was present, at the end of last year, in 1,469 points of sale from Spain and Portugal. The second reason is that in reality ‘Ready to eat’ is only one of the multiple channels that allow Mercadona to capitalize on the growing demand for already cooked food. If the entire business and its turnover in Spain and Portugal are taken into account, the level of income is much higher. How much do you earn then? In total, if we count both the business generated by the ‘Ready to eat’ section and the sale of pre-cooked food (creams, packaged chicken or refrigerated pizza, for example), Mercadona entered around 3 billion of euros in Spain and Portugal. Not only does it represent just over 7% of the company’s global turnover, it also shows a growth of 20%, which confirms the potential of that line of business. The figure helps to understand Mercadona’s commercial strategy, which has been betting on the ‘Ready to eat’ section for years (in 2025 it implemented it in 250 new super) and in recent months it has redoubled its bet, adding to its offer of dishes and desserts a new service of freshly ground coffee. The cooked food sections also play a decisive role in the so-called ‘Store 9’the new establishment format that the company wants to implement in its network. Does the data matter that much? It is certainly striking. FRS contributes another brushstroke which helps to understand to what extent the sale of pre-cooked or ready-to-eat food has grown in Mercadona. The 3,000 million euros registered in Spain and Portugal in 2025 far exceed McDonald’s annual sales in Spain (around 2 billion euros) or Burger King (others 1.5 billion). In fact, it almost equals the sum of both subsidiaries. It’s not surprising at all. Mercadona has conquered 20% of the entire food and beverage business (in value share) and ships a large part of the hamburgers with buns sold in Spain. According to the Numerator signatureis behind approximately 10.2% of consumption occasions. They are just nine points lower than the national market leader McDonald’s (19.5%). Does it only happen with Mercadona? At all. The chain stands out for its considerable market share, but it is not the only one seeking to benefit from the growing demand for already cooked food. In February, the consulting firm NielsenIQ estimated that “prepared and ready-to-eat food solutions” are growing at a rate of more than 10% in supermarkets and hypermarkets, which is in turn shaping a billion-dollar business. “Right now this segment represents a total of about 3.7 billion,” explains Nacho Biedmatechnician of the consulting firm, in an interview with elDiario. There are analysts who calculate that the distribution sector (which includes supermarkets) already monopolizes 23% of what we spend on food outside the home. Why this change? Because consumer habits are not immutable. We do not eat the same, nor in the same way nor in the same places as our grandparents. And our grandchildren probably have different habits too. I predicted it last year Juan Roig, predicting that in the middle of this century Spanish homes will no longer have kitchens, so supermarkets will become more than just the place where we buy food to fill our refrigerators: they will be our great reference in food. Beyond these changes at the domestic level, sections like ‘Ready to Eat’ play a great role. They offer customers variety, agility and, above all, rates that traditional bars can hardly match. Prepared meals from supermarkets are in a way the successors of a ‘menu of the day’ that has been in crisis for yearssuffocated by rising prices. More and more people stop going to the corner restaurant to spend 14 euros in a menu of first, second and dessert that will take you 45 minutes to consume. He goes to an Alcampo, Carrefour or Mercadona, buys a couple of dishes for 10 euros and devours them in less than half an hour in the dining room located in the supermarket itself. Many people even take cooked food to devour at home. Images | Mercadona Via | FRS In Xataka | Very few national supermarkets are resisting Mercadona: regional chains like Froiz are

6 ways to solve this problem

by

Let’s tell you How to solve the problem of some apps not showing on Android Auto. Because it can be frustrating to start your car and realize that apps are missing from the screen that were there the day before, especially if some important ones disappear, such as music ones. Therefore, we are going to tell you what things can you look at one after the other, because these problems are usually due to specific things such as the launcher configuration, permissions, or even battery restrictions or if you are left halfway after installing an app update. Therefore, we are going to review the solutions one by one. Check if the app is hidden The first thing you have to do is check if you have the app activated on Android Auto. You have to do this in Android, where you access a list of your mobile applications and decide which of them are shown or not in Android Auto when you connect it to the car. To do this, you have to enter the Android Auto settings on your mobilewhich is usually within the section Connected devices. and once inside, look for the option to customize the applications menu. You will go to the list of apps, where those that are selected will be seen in the car, and those that are not selected will be hidden. Check that Android Auto is updated Many times we don’t worry too much about updates because we assume that they happen on their own. But if Android Auto is not updated or the associated services either, there may be strange behavior or errors. Therefore, it is advisable to check Android Auto in Google Play, Google Play Services and the phone’s system update itself, if it has been pending for a while. Make sure everything is correctly updated. View an app’s battery restrictions Many manufacturers implement different systems to manage the battery and save consumption with their applications. There are options for restrict the app from being used in the background to save battery, and if one of your apps has it, it simply won’t be seen in Android Auto. To find out this you have to enter Settings and go to the section Applications to display the list of all installed ones. Now click on the one you want and you will enter its settings, where you can click on the battery section and check if it has permission to run in the background. See if the app has the permissions it needs When you use an application for the first time, Android asks you to give it permissions to access your device’s hardware, such as the microphone or location. If you have restricted these permissions to maximize privacy, the app may not work properly on Android Auto. Here, you have to enter your mobile settings, click on Applicationsand access the list of apps. Once inside, click on the one that is affected and does not appear or does not work well in Android Auto. When you do, review the following permissions: Notifications. Microphone, if it is a calling or voice messaging app. Location, if dependent on real-time services. Files and multimedia content, in some audio or navigation apps. Sometimes it could be a problem with the app There are times when the problem is not with Android Auto or any configuration, but with the application itself. Compatibility may have been temporarily lost after a poorly resolved update. To check this, you can take the following three steps: Check if the app is updated in the Google Play Store. Go to Google Play and see if it is still listed as compatible with Android Auto. Check if another app of the same type does appear, to rule out that the problem is general. With this you will be able to know if Android Auto is displaying the menu incorrectly, or if the specific application has simply changed something and no longer works as well in the car system. You can reinstall the application Turning it off and on again has been the great solution for many software problems for decades, and you can try it on your Android mobile. Another final solution is reinstall the application that is giving you problems. To do that, simply uninstall it and reinstall it.

Australia has a problem: extremely boring and monotonous roads. And it also has a solution: sign trivia

by

If you drive on Australian roads you may come across unusual signs and we are not talking about the kangaroos warning (that also), but the one that warns you that you are about to cross the “90 Mile Straight“, a stretch of almost 150 kilometers in a straight line that means spending just under two hours without turning the steering wheel. Or a sign that directly throws you a random question typical of Trivial. The objective is that your brain does not disconnect because on such a monotonous route, boredom can be lethal. In fact, Australia has some of the most dangerous roads in the world and it is not because of their poor condition or their dizzying curves, quite the opposite: they are too long, too straight and too empty. So the country is exploring different solutions to avoid this potentially deadly drowsiness. Boring Australian roads. All of these roads have decent pavement, a predictable layout, a landscape with little variation and little traffic, a recipe for disaster: The Eyre Highway takes the cake: it connects Western Australia with South Australia across the plain Nullarbor Plain (which takes its name from the Latin: treeless) between Balladonia and Caiguna: 200,000 square kilometers of limestone land with hardly any vegetation or hills. A 146.6 km straight line without a single curve that you have to travel at 110 km/h (the legal limit in most of the country). After the Saudi Arabia Highway 10is the second longest straight road in the world. The Stuart Highway It crosses the center of the continent from north to south, from Darwin to Port Augusta, traveling more than 2,700 kilometers inland on a fairly simple route that also crosses the Northern Territory. There it has large stretches through northern areas with distances up to 252 kilometers Between gas stations, temperatures of up to 45 °C are reached and a landscape monotony that has little to envy of the Nullarbor. In fact, one of the roads with the highest rate of fatigue accidents in the country, according to the Australian government. The Barkly Highway It connects Queensland to the Northern Territory via the Barkly Tableland, a flat, arid plateau where the road stretches almost straight for hundreds of kilometres. The extreme heat, the total absence of shade and the sections without signage or rest areas make it a minefield for those who travel through it. The Flinders Highway Also in Queensland it runs through the interior of the state for more than 800 kilometers. It connects Townsville with the interior through a repetitive landscape, with little traffic and long distances between towns, the ideal breeding ground for boredom. At night it is even worse. The danger of road hypnosis. The highway hypnosis or white line fever is more than just being bored and drowsy: it is an altered mental state that allows you to continue driving, responding to basic stimuli and maintaining speed, but without being aware of what you are doing. Simply put: put your brain on automatic mode. science has an explanation: Flat, straight roads with little landscape variation produce a chronic deficiency of sensory stimulation, reducing alertness to dangerously low levels, causing drowsiness and inattention. This study on the phenomenon explains that cognitive fatigue reaches its peak just 20 minutes after entering that monotonous environment, much sooner than it might seem, even for those who are driving. When the brain warns, it has already been on autopilot for a while. The consequences can be tragic: unconscious speed increases or a minimal reaction capacity that already causes havoc. In Australia, fatigue while driving is four times more likely as a cause of this road hypnosis than drugs or alcohol. In Queensland, it accounts for 20 to 30% of road deaths. A15, Queensland. Via Google Maps Trivia on signs. The solution that Australian authorities have been implementing for years is so simple that it is shocking: posters with a question and answer game. As you enter one of those boringly dangerous areas, you come across a yellow sign that warns: “Fatigue Zone. Trivia Games Help You Stay Alert” (Fatigue zone. Trivia games to help you stay alert). From that moment on, you will find signs scattered along the route several kilometers away with a question and his corresponding response. Example: Question: Who was the first Premier of Queensland? Answer: Robert Herbert. And so on. The cognitive mechanism is exactly what science describes: introducing an unexpected and irrelevant stimulus for driving that forces the brain to come off autopilot. So the driver has to read, process the question, remember and, if there is a co-driver, even debate the answer. And then wait to see the solution a little later. A simple but effective way to activate the mind. Each question and answer is glued to the panel and secured with a padlock, allowing them to be renewed. And does it work? Well, probably yes, but no one has rigorously measured it. However, in theory the mechanism is supported by neuroscience. Professor Narelle Haworth, Director of the Center for Accident Research and Road Safety Queensland, endorses his presence: “Always doing the same thing, without much stimulation, causes a decrease in alertness (…) The idea of ​​trivia games on the road is to keep drivers more attentive… perhaps a passenger who knows the answer will start a conversation.” But Haworth herself acknowledges that although the objective is in line with road safety research, there is no study that has specifically analyzed the impact of the signs. In addition, it has its limitations: the signs lose effectiveness with those who travel the same route frequently and already know all the questions. And obviously they have a quite common risk in these times: Someone might think to look at their cell phone to look for the answer. And in any case, it does not replace rest. Triple animal sign.

If your hard drives disconnect on their own, an underpowered USB Hub may be to blame. With these you won’t have that problem

by

If you usually use a hub to connect hard drives, mice, keyboards and other accessories or peripherals, perhaps at some point it has happened to you that they disconnect randomly. That’s especially worrying with hard drives, because you can lose data. Today we are going to tell you why the problem is not the hard drive, but surely the hub USB you have. The price could vary. We earn commission from these links How does a hub Hub without external power. The hubSpeaking of models that do not require external power, they are accessories that generally have fairly low prices, although it depends a lot on the brand. They act like port multipliersince connecting them to a single port on the computer (generally USB-A or USB-C) allows us to connect two or more devices to the hub. They are usually quite cheap, small and there is a wide variety to choose from, with different formats (elongated, square and even round). To use them you only have to connect them to a USB port on your computer, without the need to also connect them to a power outlet. AND here is its main limitation. The energy required to use it comes directly from the computer, so the power will be limited to what the port offers. Furthermore, the maximum power is always divided by the hub (so that it can work) and the number of devices that we connect. To give you an idea, a standard USB 3.0 gives 900 mA. A mechanical hard drive can require almost all of that to boot. If you add a keyboard with lights, the system collapses. How does a hub with external power Hub with external power. The hub with external power they are less frequent, more expensive and often larger. Here we can identify the hub assets, which are usually cheaper, and Docking Stationwhich are larger and come with more ports, including some video ones. With this type of hub We are not so limited to the power that the computer’s USB port can offer. In practice, this means that in many cases the power does not have to be divided when connecting two or more devices, although there are exceptions: some USB ports of the hub Active devices require so much energy that they prioritize these ports, something that we can see in those USB-C (Power Delivery) that are aimed at charging devices such as mobile phones compatible with fast charging. It is worth mentioning that the hubs assets come with a USB-C PD (Power Delivery) port. They don’t come with a transformer, but if you connect the laptop charger to them, they become “powered.” And… what are they for? Both the hub assets like Docking Station They are ideal if you are looking to connect devices that require high power, such as mobile phones, monitors or hard drives and SSD drives. By way of differentiation: It’s a hub passive if: It just has a short cable coming out of it and nothing else. It’s a hub active if: It has an extra port that says “DC 5V” or “USB-C Power Delivery (PD).” It is a Docking Station if: It is large, heavy, has its own power brick (like that of a laptop) and has video connectors such as DisplayPort or several HDMIs. The good and the bad of both options, face to face Hub without external power hub with external power THE GOOD 🟢 They are cheaper, more compact and lighter. They offer better stability when connecting many devices and usually have a greater number and variety of ports. THE BAD 🔴 The power is limited to what the computer’s USB port offers, so you may experience power outages in certain cases. They are more expensive and tend to be larger and heavier. Ideal for: Keyboards, mice, microphones or flash drives (pendrive). Mobile phones with fast charging, hard drives and SSD drives and monitors. We do the math to see which one can compensate you more. Both options have their positive and negative points, so the choice lies in how we are going to use them. If it is still not completely clear to you, let’s see it with an example. If you want to use a hub sporadically because you are not going to connect many devices at the same time, it may be worth it to buy a hub without external power. Actual use: Let’s say you want to connect two low-power devices. The accounts: You save between 70 and 80 (or more) euros between the cost of a hub without external power and another with external power. Also, if you chose this second option, you would not be squeezing it, since you are going to connect low-power devices. So? If you want to connect a mouse and keyboard (because they are wired or because you want to recharge them) and you still have a free USB port on your computer to connect a hard drive, this type of hub It can serve you very well. However, if what you want is to connect several devices, low or high power, and you do not have any more free USB ports on the computer or they are in an area that is not easily accessible to use them, it will be more useful for you to go for a hub with external power. Actual use: Let’s say you want to connect many devices to the hubsome need more and others less power. The accounts: You pay more for this type of hubbut it allows you to connect practically any device. So? You can have a greater number of connected devices (depending on the hub), and it will give you “the same” what to connect, whether it is a keyboard or a hard drive because it will offer a stable connection. Also, as a utility, if you have the computer under the desk or in some area that is difficult to access, you will not have to bend down to … Read more

It’s a huge problem for AI.

by

The United States (like Europe, China and the giants of the Middle East) are in the midst of a real estate race: that of data centers. Nobody wants to be left behind AI race and, for that, they need gigantic enclosures in which to train it. The big problem is that these facilities They consume a lot of energyand there China seems to have the upper hand facing a United States that does not have the best face. In fact, it is estimated that half of its data centers scheduled for 2026 will be delayed not canceled. And it is something they cannot allow. It’s not a money problem. Meta, Amazon, Microsoft and Google are going to pool more than $650 billion this year to build artificial intelligence infrastructure. To put it in context, It’s more than the Apollo program cost. that took us to the Moon for the first time or to the great railway expansion of the 19th century. It is private capital that is doing the trick, but although the State does not pay the main bill, it facilitates operations and influences the pace and deployment of massive data centers through regulatory decisions, permitting and energy planning. And the latter is vital. The tyranny of 24/7. My partner Alba coined that term a few days ago to describe the current situation in which companies focused on AI find themselves. AI is intended to help us optimize our electricity consumption by the 2030s, but right now it is only achieving one thing: collapsing the traditional grid. This technology needs a lot of energy and, furthermore, constant, which is causing collapses in the network. The estimate is that the energy consumption of these data centers will increase by 175% between now and 2030. And not only consumption: Google’s emissions have increased by 48% in the last five years and Microsoft’s by another 31%. They were two of the most committed companies with ‘net zero’ by 2050. The other bottleneck. With this in mind, and knowing that the industry is devouring resources such as NAND memories To feed the AMD and NVIDIA platforms used by hyperscalers, we must talk about the other bottleneck in the sector: the energy. On the one hand, there are the plants themselves and we already know that companies have plans for private nuclear plants, gas is booming and coal is used in peaks of demand. On the other hand, there is the equipment that is installed in the data centers themselves. We are talking about transformers, switches, dissipation equipment and batteries. Panasonic is one of the largest manufacturers of batteries for racks of data centers. They are “packages” of batteries that are inserted between the equipment so that, in the event of a blackout or maximum demand, they provide specific energy support. A few days ago they commented that its annual production had already been soldbut the problem is that orders keep coming. Bad forecasts. And there is that bottleneck that we mentioned. As they point out in Bloombergthere are analyzes that already suggest that half of the data centers planned for the United States throughout 2026 will be delayed or canceled. It will be a blow to an industry that cannot stop because there is a lot of money at stake (and even more so the year Anthropic and OpenAI want to become public companies) and where they compete against a China that does not seem to take its foot off the accelerator. The solution is to electrify the grid using renewables, but the problem is that these solutions can provide constant energy, but they are not the best to provide a lot of energy during peak periods. workouts. Large batteries would be needed and, with the parallel rise of electric cars, there are none. The Wood Mackenzie analyst group points out that the United States “does not have enough capacity to stand on its own, so its companies are forced to go to the export market.” Geopolitical paradox. And therein lies the problem. The United States and China are immersed in a technological war, but also a commercial one. This makes it difficult for American companies to buy what they need from the Chinese industry, which is what leads the way in batteries and solar panels. Jensen Huang -CEO of NVIDIA- already commented a few months ago that the international conflict was fine, but that there was no need to be short-sighted and they had to take advantage of what China has to offer. The reality is that data centers are estimated to consume up to 12 GW of energy in 2026 in the United States alone, more than ten million American homes need. And, although the electrical infrastructure represents less 10% of the total cost of a data center, it is impossible for the facility to start operating without it. Now, The US has room for maneuveranother thing is that they activate the levers.
