The European Union is successfully demolishing hundreds of dams across the continent. It’s for our good

by

When Tore Sorebakken and a team of workers reached the Vinstra River in the heart of Norway in December 2025, no one knew what they were looking for. But when they emptied the pond, drilled dozens of holes and installed 750 kilos of explosives, local authorities stopped them and asked them what why were they trying to destroy that natural waterfall. Sorebakken, surprised, had to explain to them that this was actually a dam built at the beginning of the 20th century to facilitate the transportation of wood and generate a minimum amount of hydroelectric energy. The locals had completely forgotten about it: as I say, they had no idea that it was a human infrastructure. And that is a beautiful metaphor for the enormous abandonment that European rivers have suffered for decades. Free the rivers. Six years ago, the demolition of old dams and clogged weirs was anecdotal in Europe. But in 2024 it came into force European Union Nature Restoration Regulation. It sought to return 25,000 kilometers of river to “free-flow” status before 2030. Since then (since before, really, because there were countries that began to implement it before it came into force) we have had five consecutive years of historical highs. In 2025, according to Dam Removal Europe annual reportat least 603 barriers were removed on the continent. This allowed more than 3,740 kilometers of river to be reconnected. The ‘more’ in the previous paragraph is because reconnection data is only available for 198 of the 603 barriers removed. But why do we want to ‘reconnect kilometers of river’? There are many data, but one that is especially clear is that More than 42% of European freshwater fish species are threateneds and about two-thirds are at risk of being so. Whether we like it or not, 9 out of 10 natural disasters in the European Union in the last decade have had to do with water. And having the rivers full of forgotten structures is part of the problem. ‘Taking back control’ of rivers is essential to reduce the risks of contemporary European society. But that will have consequences, right? This can be read in many places: that European policies of “dam demolition” aggravate droughts. The problem is, of course, that is inaccurate. At least, if we go by the majority of the demolitions. Almost everything that is being torn down are weirs of less than two meters. That is, small barriers that do not store water, but rather raise the sheet to divert flow to an irrigation canal, hydroelectric plant or mill. In fact, most of them should already be demolished because the concessions that allowed them have expired, but no one has paid special attention to it. Until now.

Someone thought it was a good idea to bring a Bluetooth device called “Bomb” onto a plane. What had to happen happened

by

Imagine that you are sitting in that modern torture chamber that we call “economy class” on a transcontinental plane when, after an hour in the air of the eight-hour trip from New Jersey to Mallorca, the aircraft turns around to land at the point of origin because the bomb threat protocols are activated. Now stop imagining because that is precisely what happened this past May 30 when the United Flight Boeing 767 that covered the Newark – Palma de Mallorca route thad to turn around with 12 crew members and 190 passengers of which one was the owner of a Bluetooth device with a peculiar name. “Bomb”. The “Bluetooth bomb” He United Flight 236 It should be just another conventional flight, but those who took the one last Saturday experienced an unusual adventure. When the ship was flying over the Atlantic and in a period Between 60 and 90 minutes after takeoff, someone noticed a disturbing detail: searching for Bluetooth networks, They found a device called “BOMB”. If someone was carrying a bomb with a Bluetooth connection, I highly doubt it would be visible to everyone and, on top of that, it would be called “Bomb”, but it was enough for the situation to explode. The crew, using the public address system, repeatedly asked that the Bluetooth devices be turned off, even threatening with turning around, but after seeing that there were still some lights left and that the “bomb” was among them, the maneuvers began. In coordination with the company’s operations center in Chicago, it was decided that it was best to declare a state of bomb emergency and return to Newark. The plane landed as if nothing had happened, but on the ground there was a significant police and security deployment that forced the passengers to vacate the ship, leaving their hand luggage behind. Image | Flightradar24 As part of the procedure, it was now the security forces that were going to be in charge of inspecting that luggage again. It has not really emerged what the device was, but what is clear is that there was no real explosive device. United has not given detailsbut different media indicate that a 16-year-old passenger had a device named with that name. Some say it’s a Fitbit, others say it’s a Bluetooth speaker. No details have been given about the consequences. that the passenger will have to face and everything has remained an anecdotal situation and a story that those 212 people will tell at some point. Now, there are interesting readings. The first is that there are devices for which you can change the name of the Bluetooth connection. For example, we can call our cell phone whatever we want, just like Wi-Fi networks, but there are others that are not easy to change the name of. A speaker or headphones usually have the name they come from the factory, unless they have an app that explicitly allows you to change the identifier. This is important because there are speakers like the Bombbox from JBL and, above all, the Hama Bomb 3.0 that have ‘BOMB’ in the name. Obviously, it doesn’t just say that and there are numbers and the brand, so it would be easy to deduce that it is a totally different device than a bomb. Also, if this were the case, the device would be turned off and not searching for Bluetooth all the time, so what makes the most sense is that it is a mobile phone with that ‘nickname’ for Bluetooth. That said, when the crew asked to disconnect the Bluetooth, if the person had headphones on they might not even notice and, if they did, it was a message that could be interpreted as “put the phone on.” airplane modeThere are cell phones that, when they activate airplane mode, deactivate all wireless communications, but there are also those that only deactivate Wi-Fi, the mobile network and leave Bluetooth to allow connection with headphones. This is for trying to find an explanation for a bizarre story like few others that had a happy ending for the passengers, being able to board a new flight the morning of the next day, but which could be very serious for the funny or clueless owner of the device. Because it is one thing to take longer to take off, but having a plane turn around, relocate all the passengers and the company pay compensation… is not cheap. AND I’m sure someone at United Flight isn’t happy at all.nor were those who were on that flight and who had zero information about what was happening, even having to go to reddit to find out about the movie and report the company’s compensation: a $15 bonus to spend on food. Moral: take a look at what your devices are called. In Xataka | Airplanes have circular windows for a reason. It took two plane crashes to find out.

Walking 20 minutes a day after age 55 is very good. The secret of healthy maturity is to do it much earlier

by

An increasingly repeated idea is that, to have a quality retirementyou have to keep moving throughout maturity and with adequate physical activity. The problem is that many times people wait until they are 55 years old to start taking care of themselves and in many cases because they already have a metabolic disease. And this should make us aware that the sooner we start taking care of ourselves, the better. Walk It has been crowned as the star exercise for older adults, and the scientific evidence that supports it is overwhelming. A study from the year 2023 points out that walking 30 minutes a day for 5 days a week reduces the risk of age-related diseases, although it is especially emphasized that it must be done at a high speed and that requires some effort for the body and not as a simple walk. If this is done, we will be significantly reducing the risk of suffering from cardiovascular diseases and type 2 diabetes, but also protects against dementia. And if that were not enough, a review conducted this year with 180,000 participants demonstrated an 18% to 30% reduction in mortality from all causes with moderate levels of physical activity. In figures. It’s not that Olympic records need to be broken, but simply taking 5,694 steps a day is associated with a 13% lower risk of mortality from all causes. And as we have said before, if it is done a speed high, a greater benefit is achieved. When to start. If the benefits in middle age are so incredible, why does science demand that we start much earlier? The answer lies in sarcopenia, which is the process of loss of muscle mass that we face when we begin to age without doing any type of strength exercise. And that is why the deadline of 30 years is set to begin to remedy it. Because? From this age onwards, it has been seen that between 3% and 5% of muscle mass is lost per decade. according to the NIHand other studies suggest that this figure can be between 3% and 8% per decade after age 30. AND from 60 years old the rate of decline becomes even greater. With all this information, it is estimated that right now between 10% and 20% of older adults suffer from sarcopenia, and lack of exercise is the main factor that worsens this progressive muscle loss. The recipe. The WHO here is very clear in its guidelines and, curiously, it does not make reductions upon reaching retirement, so it does not understand a specific age from which you must exercise no matter what, but rather it points out that you should always do it. That is why their recommendations are exactly the same for adults from 18 to 64 years old as for those over 65 years old: relativize. Between 150 and 300 minutes a week of moderate aerobic activity (such as walking), or between 75 and 150 minutes of vigorous intensity. Furthermore, the WHO asks to incorporate muscle group strengthening exercises at least two days a week for all adults. In the specific case of adults over 65 years of age, the only difference is that activities that improve balance must be added to the general recommendations three or more days per week to avoid fatal falls.

If you are very good at your job and your boss sends you more tasks than the rest, share this article

Being the most committed employee in the office has a serious health risk: the more someone enjoys their job, the more trouble they end up making. things that don’t belongwhich are not going to add to your career and which, over time, can end up burning him. At least that’s what he claims an investigation from Cornell University and Northeastern University in which 4,300 employees from different sectors have participated. As and as he declared Sangah Bae, one of its main researchers, Northeastern Global News, This study was born from his own experience as a junior analyst in Chicago: the more involved he became, the more extra work fell on him. Years later, data confirm that this pattern was no coincidence. It’s not a coincidence: it’s a pattern. The researchers found that managers tend to assign additional tasks to employees who perceive as more motivated. In a field survey with 834 middle managers, 55% chose the employee they considered most motivated to assign extra tasks, even when the managers had data on variables such as age, experience or work performance, the perception of the employee’s motivation prevailed in their choice. The laboratory experiment was even more revealing since the researchers designed groups of three people in which one played the role of manager and the other two as employees, competing for a financial bonus linked to their performance. In this scenario, 74% of those acting as managers assigned the extra task to the most motivated employee, even though they knew that this hurt their chances of collecting that bonus. As a result, only about 31.37% of the most motivated employees ended up receiving an extra bonus for their performance improvement. Motivational oversimplification. According to the study According to Bae and Woolley, behind this tendency is a specific psychological mechanism that researchers have called “motivational oversimplification.” The manager’s reasoning is based on the fact that, if this employee enjoys his main job, he will probably also enjoy any extra task equally, even if it has nothing to do with what he usually does and is monotonous and routine tasks that they do not contribute anything. The researchers say that managers “can assume that employees who enjoy their main job will also enjoy additional tasks and that this enjoyment will protect them from burnout.” That is, if it is assumed that the employee will enjoy the task, it is assumed that it will not cost him that much to do it. The study data quantifies this perception gap: managers estimated a drop of just 0.2 points in the motivated employee’s job satisfaction when assigned extra work, while affected employees reported a drop of a full point on that same scale. When motivation turns against you. In one of the study tests carried out over a period of six days, managers chose the most motivated employee 69% of the time, which is equivalent to an average of 4.2 out of every 6 extra tasks assigned. This assignment pattern was repeated every day, which suggests that managers generate systematic inequality in the workload within their teams without being aware of it. “When managers have to assign extra work to their employees, they opt for the easiest option: a person they can trust. That employee who is your shortcut, that person you turn to regularly, who seems to be engaged and enjoy their work, could actually be silently suffering burnout,” Bae said. …and the motivation runs out. As revealed the study OSH Pulse 2025 of the European Agency for Safety and Health at Work (EU-OSHA), 44% of EU workers are regularly exposed to task overload. In Spain, this percentage reaches 49%, and one in three European workers (29%) acknowledges having suffered stress, depression or anxiety caused or aggravated directly by their work in the last twelve months. In Spain, the number of employees affected by task overload rises to 40%. As and how they stand out in Harvard Business Reviewthe study by Cornell and Northeastern Universities adds a new variable that these occupational health data do not include: this burden is not distributed randomly among all employees of a company, but rather tends to concentrate precisely on the employees who are most involved.

DeepSeek is good, pretty and very cheap. And above all, the weapon to create a Chinese hardware industry independent of Nvidia

by

The arrival of DeepSeek-V4-Pro It hasn’t caused that much of a stir. like the one caused by DeepSeek R1 a year and a half ago, but we may be facing an even more important model. If that version revealed to the world that China was advancing spectacularly in this race, this other one is beginning to allow us to glimpse something else more interesting. What most people see is a very decent model and above all “low priced”. Which hide the company It’s another more important thing: achieve independence from Nvidia and US hardware. what has happened. Last Friday, those responsible for DeepSeek announced something surprising: their promotional offer with a 75% price cut to use their DeepSeek-V4-Pro model will be maintained permanently. That makes this model offer very decent features (but not exceptional) for a really low price: 1M entry tokens 1M tokens output DeepSeek-V4-Pro 0.435 0.87 GPT-5.5 5 30 Opus 4.7 5 25 Gemini 3.5 Flash 1.5 9 Good, pretty and very cheap. It is true that the performance of DeepSeek-V4-Pro is inferior to that of rival models from OpenAI, Anthropic or Google. Artificial Analysis tests indicate that the DeepSeek model is at a very good level, but it is also much cheaper than its competitors. This is especially relevant for agentic tasks that consume many tokens and that with this model become accessible and very affordable. According to Artificial Analysis, DeepSeek is close to the performance of the best models in the industry, and although it is slower in its responses, it is also much cheaper than the frontier models from OpenAI, Anthropic or Google. A different strategy. How is this company going to make money? It does not have subscription plans like its local competition (GLM, Kimi) or the western one (ChatGPT Plus, Claude Pro). It also does not have voice or image models. It does not have an AI agent for programming that competes with Claude Code. It publishes the open weights of its models and shares its technical innovations with the industry (and with its competitors). For those who closely follow the company and these decisions, the strategy is clear. DeepSeek’s goal is not to win the AI ​​model race. Their goal is to build a Chinese AI hardware industry that doesn’t depend on Nvidia or TSMC… and get paid their share in that process. Hardware independence. China has a structural problem in this AI race: sanctions and vetoes imposed by the US make you unable to access the most advanced chips nor to ASML UVE photolithography. And since China cannot currently compete in terms of computing power, what its companies are doing is ensuring that their AI models need less computing power to achieve similar results. Efficient architectures. The Mixture of Experts (MoE) and Multi-head Latent Attention (MLA) architectures are two key weapons in this strategy. The first already existed but was adapted by DeepSeek for their model: with it only part of the total parameters of the model are activated to answer the query without losing precision. What MLA does is compress the attention information (the so-called KV Cache) with which the model maintains the context of a conversation, reducing it by 90%. Both techniques allow us to reduce the need to use high-speed HBM memories, something that is also striking in order to reveal DeepSeek’s probable strategy. The importance of KV Cache. As the GDP analyst explains in Xthat use of MLA allows that for one million tokens, DeepSeek-V4-Pro only needs 5.48 GB of HBM memory. Competitors like Zhipo AI, which develops GLM 5, need 60 GB for the same, while Alibaba’s Qwen 3 needs 89 GB. This advantage allows DeepSeek to offer much lower prices to obtain performances similar to those of its competition, but it also means that DeepSeek models can run on Chinese memory chips that cannot compete in speed with HBM modules. Goodbye HBM, hello NAND and SSD. These innovations open the door to the use of NAND memories and even SSD drives to process this data, and there YMTC enters the scenea Chinese Flash memory manufacturer that is slowly becoming a global giant. Also CXMTwhich manufactures DRAM memoriesbecomes an alternative here and the reason is equally interesting: DeepSeek introduced a memory search module in LLMs called Engram which is also intended to avoid excessive dependence on HBM memories. How to bypass the CUDA monopoly. Nvidia continues to have a fundamental element in CUDA to maintain its market dominance, but here DeepSeek too has proposed an alternative. Is called Tile Kernels and these are software cores created with TileLang (a variant of Python for this field) that allow governing advanced AI chips (GPUs). Huawei as an invisible ally. Those responsible for Huawei recently indicated that its new Ascend AI supernodes fully support DeepSeek v4 models. Precisely this provides another fundamental advantage to the company, which thus avoids (at least in part) total dependence on the use of Nvidia chips and prepares to further strengthen Huawei’s relevance in a market in which until recently Jensen Huang’s company was queen and mistress. Open models to attract the hardware industry. US companies continue to maintain their closed and proprietary models, but DeepSeek is one of the many Chinese startups that publish them with open weights. With this, what she and the others intend to do is not only attract AI developers and users, but also create a hardware ecosystem that adopts these architectures. DeepSeek invites its rivals to use techniques such as MoE or MLA precisely so that all these advances become a de facto standard and hardware manufacturers also adopt them and integrate them in an optimized way into their designs. A round of 10,000 million to advance. The company is also preparing a financing round in which they intend to raise 10,000 million dollars and with which they would achieve a valuation of between 45,000 and 50,000 million dollars. Still far from the mammoth valuations of OpenAI or Anthropic (already close to a billion dollars) but certainly … Read more

If you wake up tired on a regular basis, your rest is fragmented. The good news is that science knows how to fix it

by

When the alarm clock rings in the morning, many of us ask to stay five more minutes between the sheets. But sometimes these five minutes are not for convenience, but for necessity, since there are people who wake up as if you haven’t slept at all. And this is a problem, since waking up tired on a regular basis is not normal. The myth of hours. Sleeping eight hours seems the standard that we must follow to be able to rest well, as occurs with the mantra of take 10,000 steps a day to have good cardiovascular health. The problem is that there are many people who can sleep eight or more hours and feel in the morning as if they had not slept at all, and here science suggests that real rest is given to us sleep phases and how time is distributed in each of them, not in the global calculation. The distribution. Sleep is not a linear state, although it may seem that way to us. The reality is that while we are with our eyes closed, we are going through a complex cycle of fragile architecture that passes through light phasesdeep stages and the well-known REM phase where dreams occur. But here what interests us most is deep sleep, which is responsible for physical restoration and the immune system, so when this cycle is broken repeatedly during the night, which is what It is known as fragmented sleep.the direct impact the next day is a decrease in cognition and an increase in fatigue, regardless of the hours we have spent lying down. Sleep or fatigue. For some they may be similar terms, but the truth is that they are quite different, since, while drowsiness is the biological and overwhelming need to sleep, fatigue, on the other hand, is a lack of physical energy or mental motivation. If what you feel when you wake up is fatigue, the origin may transcend the pillow and there may be a medical cause such as anemia, hypothyroidism, depression, chronic stress or the side effects of certain drugs that may be behind this lack of vital energy. Two culprits. Among the medical conditions, there are two that stand out above the others. The first of them is the sleep apneawhich is undoubtedly the great invisible saboteur, since it causes breathing to stop and restart repeatedly throughout the night. These drops in oxygen cause micro-awakenings that the brain uses to survive and breathe again, which we are not aware of. The problem is that these shocks prevent deep sleep from being achieved and result in extreme fatigue. The other culprit is sustained insomnia, since, beyond the difficulty in falling asleep, insomnia also manifests itself with early awakenings or constant interruptions, greatly reducing the restorative nature of rest. It can be corrected. Once medical causes are ruled out, there are several tips that can be followed to have a better quality of sleep. The first of them is to stay away from screens before going to sleep, since if we are already close to falling asleep and our body is preparing for it, exposure to blue light and stimulating content can cause it to take longer to fall asleep. Another very important tip is for dinner, which should ideally be as light as possible so as not to feel very heavy all night and also keep it as far away from bedtime as possible. This is where British time has a clear advantage over ours, as it means you don’t go to sleep with dinner food still in your stomach. The environment matters. In addition to removing any television from the room where you are going to sleep, the comfort you have is also important. This involves having a suitable mattress and ensuring that the temperature of the room is not uncomfortable, since this will cause awakenings that will cause you to not finish resting. This is also added to the need to have as little noise as possible. What is done during the day It matters a lot to sleep, and here exercising several hours before bed can make you sleep much better. But in the diet you also have to be very methodical, since you have to limit caffeine in the afternoon or at night, and limit alcohol consumption which, although it seems to put us into a very deep sleep, the reality is that it makes it not at all restorative.

My PC case makes what’s inside an oven. I want one with good airflow and this is the one I have on my radar

by

I assembled my PC in parts back in 2021. Five years have passed and, since then, I have been little by little changing some parts. First it was the graphics card and later came the sudden change: I jumped to DDR5 with motherboard, processor, new air cooler and RAM memory (yes, before prices skyrocketed). The box is the same and that has been a problem lately: my PC is an oven if I demand a little from it. He airflow (i.e. airflow) of it is not good enough for the configuration I have right now and I think it’s time to change. For several reasons that I will explain a little below, the one I have had in my cart for a few hours is this Corsair Air 5400 RS-R ARGB: costs 156.50 euros. That its RRP is almost 280 euros is one of these reasons, but not the only one. CORSAIR Air 5400 RS-R ARGB Triple Chamber Panoramic Mid-Tower PC Case – 3 Pre-Installed RS120-R ARGB Reverse-Rotor Fans – High Flow and Low Noise Ducting – Black The price could vary. We earn commission from these links A box with good airflow and cable management system Let’s go in parts. The first reason I like this box is not the most important, but I love its design. Both the front and the side are made of tempered glass, allowing you to see the interior at all times. In fact, they are two independent panels that connect and both can be opened. This allows you have much more space and leeway to remove components or to clean the inside (something I have to do constantly because I have two cats at home). The above is combined with a cable management system that is not only quite tidy and easy to place, but it remains hidden. Since you have a box with a very cool design that allows you to see what is inside, it is better if it is with the fewest cables visible. However, the best thing about this box is that it has a triple chamber design. What does this mean? Which is designed so that the parts that generate the most heat (such as the graphics card, power supply or processor) have an independent air flow that allows them to be well cooled. It is worth mentioning that the box includes three 120 millimeter air intake fans, although it has enough space to place three more of these, both in the front and on the top. All of this combined with the fact that it is currently historical minimum price It makes it a box that seems to me to be one of the best options available right now.

I was looking for a good keyboard and I wanted one that would help me work faster (and more comfortably). I already know what I want

by

Between the time I spend working and the time I spend playing on the PC, it can be said that I have my hands on the keyboard for many hours of the day. For years, peripheral that has accompanied me has been a Logitech G513 from which I have learned that I love the wrist rest. However, I think it’s time to retire and I want something different. Since I spend all day browsing almost every store and looking at all kinds of devices, I admit that I have spent more time than necessary searching for a new keyboard. And, in that search, I have found The keyboard that I would like to be part of my setup: This is Corsair Galleon 100 SD and costs 349.99 euros. It has a high price, I know, but there are several reasons why I love it. Corsair Galleon 100 SD RGB Wired Mechanical Gaming Keyboard – Spanish QWERTY, Stream Deck Integration, Pre-Lubricated and Interchangeable MLX Pulse Key Switches, SOCD FlashTap, 8000Hz The price could vary. We earn commission from these links Keyboard with wrist rest and Stream Deck. all together As I say, there are several reasons for this and the first and foremost is what stands out most about this Galleon 100 SD: it is the first keyboard to have a built-in Stream Deck. Beyond the fact that it eliminates something that I had left over from my Logitech (the numeric keypad), this part is super useful and, although it is a gadget that has gained popularity among streamers, It is the best there is to increase productivity. What can be done with it? Well, that’s the fun, since it is very customizable. The simplest thing is to assign each key to open an app, such as Slack or an email manager. This is great, but you can go much further by making A single button opens all the applications you need to work at once. What’s more, you can place specific functions from programs like Excel or Photoshop as well, which allows you to optimize (a lot) the workflow. And to place certain functions when playing it also seems wonderful to me. I have talked about the wrist rest as a point that I love, but a small nuance must be made here. Many of these accessories that can be found on Amazon or similar stores are made of plastic and, although they do not have to be bad, I find them uncomfortable. However, this Corsair has a memory foam wrist rest like the Logitech keyboard I already have, which provides great comfort even if you spend a lot of time with your wrists resting non-stop. Finally, two more details. Its switches, which are MLX Pulse, have short travel and, although they offer an audible response, They don’t sound like an old typewriter.. Furthermore, although it is not something that matters for working, it has a polling rate of 8,000 Hz, which makes its response time very top. I left out some extra things that this Galleon 100 SD has such as the LCD screen, the wheels to control the sound or the materials of its keys, but even so it is an option that seems like a real spectacle to me. It is not a keyboard for everyone nor is it an economical option, as I say above, but it is a very interesting option if, like me, youYou spend many hours with your hands on the keyboard to work and play.

There is a battle to have the AI ​​model that programs best. And a good, pretty and very cheap rival has appeared in it: Cursor

by

Cursor has introduced Composer 2.5a generative AI model specifically intended for one thing: programming well. How good? Well, according to this startup, it does it as well as the best models of the moment, Claude Opus 4.7 and GPT 5.5, but it also does it for a lower cost. The challenge is striking not only because of what it means for Cursor, but because of how they have created that model: it turns out that it is based on a Chinese AI model. AI models specialized in one thing. While OpenAI and Anthropic try to develop general-purpose models—they do a lot of things really well— Cursor you have decided to focus on a specific task. The AI ​​startup has created an AI model specialized in programming, and has done so by arguing that a billion parameters are not necessary to compete with the best. Devoting yourself to a single thing allows you to not only gain efficiency, but also costs. This is not a decathlete, but a specialist in the 200 m event, so to speak. As good as GPT-5.5 or Claude Opus 4.7? That’s what they say in Cursor, because according to their tests with several specific programming benchmarks, the performance is on par with those two models that today are the great references both in programming and in other areas. And much cheaper. These results are also especially interesting when we add the cost factor. The average cost per task in the CursorBench 3.1 benchmark showed that Composer 2.5 managed to solve almost 65% of all tests for a cost of just $0.3. Opus 4.7 max and GPT-5.5 xhigh managed to reach that 65%, but at much higher costs: just over 4 dollars in the case of GPT, and 11 dollars in the case of Opus. The difference is abysmal. He API access price demonstrates the differences: 0.5 dollars per million input tokens 2.5 dollars per million output tokens, when Claude Opus 4.7 is 5/25 and that of GPT-5.5 is 5/30 respectively. Textual feedback. Unlike models that only learn from the final result, Composer 2.5 has been trained with a reinforcement learning technique (Reinforcement Learning) that allows us to offer clues about what is happening if errors are being made. This allows the model to recalibrate and act as a transparent teacher. One that also corrects word by word as it solves the exercise, not just when seeing the final result. 85% of the training budget has been dedicated exclusively to reinforcement learning, calibrating the model not for chat, but to execute code refactorings or fix bugs in real time. A model “born” in China. Those responsible for Cursor themselves have explained that Composer 2.5—like its predecessor, Composer 2launched at the end of March—is a model derived from Kimi K2.5, the AI ​​model of the Chinese startup Moonshot. Although that is the basis, already in Composer 2 the training and post-training tasks manage to improve the behavior in a very notable way in programming benchmarks and also in others such as Terminal Bench that evaluate the agentic behavior of these models. Cursor gets older. This startup became famous for creating a programming AI agent that was a pioneer in that fever we live for vibecoding. The user experience is no longer that of programming, as in traditional IDEs (Integrated Development Environments), but rather that of directing the machine to program it for you. Composer 2.5 doesn’t just program: it understands the structure and relationships between files, and turns Cursor into a much more competitive AI company, because it no longer depends on being able to work with Anthropic or OpenAI models, for example. Having both the AI ​​agent and the model processing everything makes it a much more competitive solution. Elon Musk has Cursor in his sights. Cursor’s good performance has led to growing interest in buying this company even before it becomes too big. Elon Musk knows this well and Grok, xAI’s model, is not so popular in the programming field. In April we learned that SpaceX had reached an agreement that gives you the option to buy Cursor for 60,000 million dollars. It would be a promising deal for both, because Composer 2.5 has already used Colossus’ infrastructure to train, and xAI could thus try to gain market share in the juicy enterprise sector.

Sony has launched the most anti-2026 high-end mobile. It’s an idea as good as it is risky.

by

Sony continues launching mobile phones. And it has reached a point where the news is not that it has launched a mobile phone, but rather why it has done so and what it wants to tell the market when it does so. Although it may seem like a counter-current idea, launching mobile phones knowing that you are only going to sell them makes some senseand Sony is not alone there. The anti2026. For some reason, manufacturers have been convincing us for years that more than useful technologies should disappear. All in pursuit of a more minimalist design, larger batteries and an evolution close to that of the portless mobile. To this, Sony responds with a blunt “hold my cap.” The Sony Xperia 1 VIII. He Sony Xperia 1 VIII It is a return to the past, maintaining technologies that the vast majority of its rivals discarded years ago. It has a 3.5mm headphone jack It has a slot for microSD cards up to 2 TB Thick, very thick bezels The SIM slot is not removed with the tool, just press it The stereo speakers are front-facing, there is no one below There is no trace of what might look like an iPhone Very good. Sony’s proposal is clear: in the middle of 2026 you can enjoy technologies that one day we banished and that are useful despite the passing of the years. Furthermore, each and every one of these steps does not distance the Xperia 1 VIII from what is required of a modern flagship. The best Qualcomm processor A powerful camera system with ZEISS optics Up to a generous 16 GB of RAM The only unforgivable point is that of a Full HD+ panel. On a 1,499 euro mobile phone this resolution is not acceptable. Because. The short answer is that Sony is not launching the Xperia 1 VIII to compete with Samsung or Apple. He gave up that battle a long time ago. In the last Corporate Strategy MeetingSony president Kenichiro Yoshida made it clear that the smartphone division does not exist to sell volume, it exists to prove something. Sony Xperia is, above all, a technological showcase. In addition, the Xperia division is a fundamental pillar for the company’s R&D. The advances made in these smartphones are later applied to what really matters: the brand’s cameras.
