tested

I have tested the Logi Dock, the combination of USB-C hub, speaker and microphone for video calls. It’s a sum that makes a lot of sense.

by

I have been working from home for nine years. It wasn’t long ago that I realized that my laptop, a 2021 MacBook Prois the answer to a question that no one has ever asked me: “what do you want, power or flexibility?”. I answered flexibility, but I didn’t know until it was too late. The MacBook Pro is always on the table, but sometimes it also travels or I take it to the cafeteria when my head demands a different environment. It is a desktop computer that from time to time has to go outside. Logitech, who knows a lot about peripherals and how we work, has understood this very well. The Logi Dock is not just a hub of ports to compensate for the fact that recent laptops are not as generous in ports. It is a value proposition that goes beyond: it is an operations center that stays on the desktop while the laptop comes and goes. One USB-C cable to connect everything when you arrive, one to disconnect everything when you leave. That, in practice, has a higher value than what appears on a specification paper. Behind the dock there…: HDMI 2.0 (4K, 60Hz, HDR). DisplayPort 1.4 (4K, 60Hz, HDR). 2 USB-A (USB 3.1 at 5 Gbps). 2 USB-C (USB 3.1 at 5 Gbps) 1 extra USB-C on the side with 7.5W fast charging. and USB-C upstream dedicated to 100W for the laptop. All in a single connection strip that you never touch again. What it does not have is Thunderbolt, Ethernet or card reader. View of the ports of the Logi Dock. A side USB-C is missing, designed primarily for charging the mobile phone. Image: Xataka. There’s that USB-C on the side. Image: Xataka. Immediately the most important question about this product appears, which deserves a completely honest answer. A hub USB-C generic costs between 30 and 80 euros. This dock right now it costs from 276 euros on Amazon. What justifies paying five or ten times more for the Logi Dock than for a simple hub USB-C? That’s the gist. The short answer is that it depends on whether you need what’s extra, not whether you appreciate what’s equal. Ports are ports. What sets the Logi Dock apart from any other hub random are two things: the speakers and the microphone. And that changes the equation… for a specific user profile. In my case, I have had it connected to the MacBook Pro M1 Pro and the Huawei MateView 28 inches. Keyboard, mouse, Scarlett 2i2 interface with the Rode PodMic for the podcastand charging the laptop at 100W. A cable from the Mac to dock. Everything resolved. I start with what does not have a hub anyone and it does have the Logi Dock: the speakers. My Huawei monitor has a built-in speaker that does the bare minimum. And those on the MacBook, which stays closed to one side, are “trapped.” With a hub Generic would have solved the connectivity, but not the audio: the Logi Dock provides good speakers and a microphone designed to not sound boring during video calls. The buttons are designed to be used as quick access during video calls, and also to join them directly with Logi Tune. Image: Xataka. Image: Xataka. The Logi Dock’s 55mm drivers with their side-mounted passive radiators produce full-bodied sound, some bass, and enough clarity to listen to music while working. It is not an audio monitor. But it doesn’t pretend to be either. In the video calls in which I have used them, giving up the headphones, the microphone beamforming six capsules works well. My interlocutors do not complain and background noise is reasonably attenuated. The real argument for the Logi Dock is not that it is the best at anything, but that He’s good enough at everything at once. The texture of the fabric mesh, in macro photo. Image: Xataka. Three months of use have also shown me where it is weak. No Thunderbolt, no Ethernet, no card reader… The touch buttons on the top panel work fine, but calendar integration via Logi Tune is the most dispensable part: with the Mac you already have your notifications, and join a meeting with a tap on the dock It is a shortcut that in practice you almost never use. It sounds like a function forced in to reinforce its proposal and better justify its existence. In my opinion that value is not there. What you do use, every day, is the most difficult to quantify: the absence of friction. He dock It’s been plugged in for months and has never given me a single problem. does not ask drivers to reinstall or annoying updates, the ports work well and there is no audio that is lost when waking the Mac from sleep. Is it worth paying five times more than a hub generic? If your desktop already has good speakers and a microphone, or if you simply prefer using headphones, probably not. Buy the hub cheap and you will save. But if in your case the Logi Dock becomes the only real speaker on the desk, the microphone in meetings and the only cable that connects and disconnects the laptop every day, then the comparison is no longer with a hub of 60 euros. It is with “a hub “more speakers, more microphone, plus the convenience of everything coexisting without conflict in a single block.” And that last comparison is won by the Logi.

The next treatment for depression could be in the eyes. They have already successfully tested smart contact lenses on mice

by

Drug-resistant depression is one of the greatest challenges of today’s medicinesince when antidepressants they don’t workpsychiatry and neurology have to resort to therapies such as electroconvulsion. Now, a team of researchers has given this issue a radical turn by developing smart contact lenses capable of treating depression by stimulating the brain through the retina. a study published in the magazine cell shows very good results in mouse models with the use of these contact lenses which have made it possible to reverse the depressive phenotype with a capacity comparable to that of the antidepressant fluoxetine, or better known as Prozac. It is not invasive. To understand the milestone that this study represents, we must first look at the current therapies that involve using what is known as Transcranial Magnetic Stimulation to be able to do non-invasive neuromodulation for patients with drug-resistant depression. The possibility of transcranial electrical stimulation by direct current is also being studied. But the problem with these therapies, which are at the bottom of psychiatry, is that reaching the deep regions of the brain without resorting to surgery is extremely difficult. And one of the risks of applying a strong electric field from the outside to reach the depths of the brain can end up damaging part of the brain. The solution. This physical inconvenience is where temporal interference technology comes in. As detailed a review done in 2025this stimulation is a great strategy, since it consists of applying two high-frequency electrical currents that do not affect the superficial brain tissue. In this way, when crossing in the deep areas of the brain, the frequency difference creates a new low-frequency wave that does stimulate the target neurons. It is a functional concept that was demonstrated for the first time in mice and that allows access to the depths of our anatomy without a scalpel. Some contact lenses. Under this principle is where we are now looking for a way to apply it in a way that is comfortable for the patient and is where the use of contact lenses equipped with electrodes made with gallium and platinum oxide comes into play. Here the direct anatomical connection that exists between the eye and the brain through the optic nerve is used to transmit this stimulation through the retina which allows temporary interference signals to be sent to the neural networks involved in depression. The application. In the research, this stimulation was simply applied for 30 minutes a day for three weeks in the rodents. What was achieved here is a restoration of healthy brain oscillations and a behavioral improvement that, according to the researchers, is comparable to that obtained by administering fluoxetine in these same animal models. Caution. Here we must keep in mind that this is the first time that contact lenses have been used to treat a brain disorder, and although the design of the device is a display of engineering, we must be cautious. As is often the case with these advances, the transition from the laboratory to the patient is very slow due to the need for numerous trials to assess the effect and safety in humans. But the idea is already on the table right now and we just have to wait for science to continue advancing.

giant trains with 1,900 seats that are already being tested

by

Madrid is immersed in the renewal of its Cercanías. The Autonomous Community has been demanding greater investments for years to modernize infrastructure and expand its capacity, suffering from overcrowded trains and recurring breakdowns. Part of these renovations will come with 79 new trains that significantly expand the capacity of the lines. And some have already arrived for their tests. The Cercanías in Madrid. It has become a political battle between the central and regional governments. One more. But the truth is that Cercanías Madrid has been suffering continuous delays and overcrowded trains on many of its lines for years. For testing, In 2018, Fomento already had reports that the regional network was saturated and needed urgent modernization. That same year, it was announced Comprehensive Improvement Plan for the Madrid Cercanías Nucleus 2018-2025 with a planned investment of more than 5,000 million euros. It includes various improvement actions such as the actions in Atocha or Chamartín (which remain ongoing) but as far as is palpable for the average user, the improvement has barely stopped at the improvement of the Recoletos tunnel between Atocha and Chamartín. On the horizon there are various expansion actions, both in the north and south of the region. This lastIn fact, it is associated with the comprehensive renovation of line C-5the one that moves the most passengers in Spain and which will be improved to accommodate new 200-meter-long Stadler trains that, right now, do not have enough space for their journeys. New trains. Taking into account the saturation of the lines in large urban centers, In 2019 Renfe puts out to tender the purchase of 211 new trains. The text already states that there is the possibility of purchasing another 120 additional trains. The value of the contract is 2,270 million euros. This contract anticipates the arrival of 176 100-meter trains and 35 200-meter trains. Among the 100-meter-long trains, 79 of them correspond to high-capacity models. Stadler, who won the contract together with Alstomis responsible for supplying its T100 and T200 models. In both cases they are trains that have already arrived in Madrid but, at the moment, they are in the testing phase in Aranjuez. The objective is that “at the end of summer” they are already in operation the first units in Madrid. five trains. It is, for the moment, the forecast proposed for that first landing on Madrid’s roads. The fleet renewal project involves the incorporation of three Stadler T100 trains and two T200 units, which are currently in the testing phase for homologation. Once they join, The capacity will grow by 20% compared to the current Civia. In the case of the T100, the increase in passengers is limited because both models (the existing ones and the new ones) have around 900 seats but the T200 increases the capacity to 1,884 passengers. The T100 model has a mixed height since two of the four cars are double-deckers. In addition, a fifth car can be added and provide the same service as the T120. For their part, the T200 are larger volume trains with two floors in all their cars, but their size can be reduced to 160 meters, which facilitates their versatility and can be used on lines where larger trains do not enter the stations. The new trains will be able to move from eight to 16 bicycles inside What improvements will we see? Both train models have Greater interior space for travelers with a more open layout and specific spaces to transport bicycles (eight in the T100 and 16 in the T200) and strollers. Improvements in Wi-Fi and an increase in available sockets for charging your phone are also promised, as well as improvements in car air conditioning. In addition, of the 10 doors of the T100, six of them will not have steps (12 of 20 in the T200) so the Ministry of Transport promises safer and faster ascents and descents. A new passenger information system has been added, they will have a new interior surveillance system and can reach up to 140 km/h maximum speed. When and where? As we say, at the moment the project involves the incorporation of three T100 trains and two T200 units late summer 2026. Renfe assures that these trains can operate on all Madrid routes except for line C-9, which is the one destined for Cotos and due to its high mountain characteristics, they cannot accommodate trains of this size. What is not confirmed is which lines will be the first to receive the new Cercanías trains nor on what date the fleet of 79 trains that must arrive to the Madrid service will be fully available. For now, the Ministry of Transport promises that before the end of the year we will see 17 new trains on Madrid’s tracks (nine Stadler T100 and eight T200). The remaining deliveries should arrive gradually but there is no definitive date for their arrival.

The CNMV has tested AI to invest in the stock market for ten months. The conclusions are very revealing

by

In recent months there has been a recurring discourse that we see on social networks and that sell us again that “get rich quick” message. That message is “use AI to invest in the stock market.” The interesting thing comes when we see how the CNMV has published a study in which it has precisely attempted to analyze that premise. Although this organization warns of the risks of investing with AI, there is another important message in the conclusions: LLMs are not bad investors per se. They are bad at following vague instructions, which is just how most people use them. The CNMV study. Two researchers from the CNMV, Ricardo Crisóstomo and Diana Mykhalyuk, have published a study methodologically serious (but imperfect) and very interesting: they used four AI models for ten months live, from April 2025 to January 2026. They chose ChatGPT, Gemini, DeepSeek and Perplexity as models. The process was simple but demanding: each month they asked each model to identify the five stocks in the Ibex35 index with the best expected performance (to buy) and the five with the worst expected performance (to sell short). Then the real result was measured at the end of the month, and here there was no historical data selected just because: the real market was the only arbiter of all the functioning of the models. The models evolved. One of the most significant aspects of the study is that its creators recognized a methodological problem that was difficult to avoid: during those ten months, the versions of the four models were updated several times. The Gemini of April 2025 was not the same than that of January 2026for example, and that could influence the results. The researchers commented that it was impossible to know with certainty whether an improvement or deterioration in performance was due to the prompt strategy, market conditions in that period, or simply because the model changed. The prompt is everything. Three were also tested prompt types very different, and that gave rise to conclusions that were neither alarmist nor did they create false expectations: they were “it depends.” Thus, their results showed that everything depended on the type of supervision that these models had: If the LLMs were asked generic questions such as “What stocks should I buy?”, they failed repeatedly. There were computational errors, incorrect interpretations and also the famous hallucinations of chatbots. Curiously, the only one that made a profit was ChatGPT. The problem is that people who use AI to invest probably use this mode of action. But if prompts prepared with iterative reviews and human supervision at each step were used, Perplexity achieved a monthly return of 3.5% on the IBEX35. Gemini and ChatGPT also improved their behavior if given more precise instructions, and DeepSeek was the worst ranked overall. There is another finding: when models receive official regulatory documentation or business results reports, their predictive accuracy improves significantly. The LLMs they reason better on concrete and verified facts than generating analysis from scratch on information that they themselves search for on the web. financial hallucinations. The CNMV study points out that financial markets are especially demanding for AI models because they require complex processes. They have to retrieve and collect information dynamically, they have to reason in multiple steps, they have to be numerically precise, and they have to know this market, and all in real time. Chatbots are trained to generate “convincing” textsso the incentive here is that the investment recommendation “sounds good” even though it is completely wrong. The confidence with which AI models present incorrect financial analysis is proportional to the risk they pose to those who use them without checking whether what they say makes sense. In short: do not trust AI to invest right off the bat. The Reddit user’s experiment was equally striking, but hardly conclusive. Source: Reddit. The Reddit experiment. A Reddit user named Blotter-fyi rode in November from 2024 a platform called Rallies.ai which gave several AI agents access to real-time financial data and money to make stock market operations. Four months later, with the S&P index down 7% since the start, five of the models are outperforming that index, although only two have positive returns in absolute terms. The author himself was the first to warn that four months are insufficient to reach a conclusion: it could be luck, the market or simply the prompt. Nof1’s experiment was fascinating, but it made it clear that AI models don’t typically make money investing in crypto. Source: Nof1. Nof1 and crypto fascination. Another particularly striking experiment was the one that the company nof1.ai made with its Alpha Arena. He put six AI models to compete, gave them 10,000 real dollars each and gave them two weeks to trade cryptocurrency derivatives without human intervention. The most striking result was not who won, but who lost: GPT-5 ended with more than 25% losses and Gemini with close to a negative 40%. Meanwhile, the Chinese models Qwen and DeepSeek dominated in terms of good performance. They iterated with other models, 32 in total, and of all of them only six achieved a positive return: the rest lost money. Grok-4.20 was the big winner ahead of GPT-5.1 and DeepSeek v3.1. Maybe you shouldn’t just let AI invest for you. The conclusions after these experiments are clear. Four months of a model outperforming the S&P index in a bear market does not prove that AI is a good investor. Only in that specific period, with that specific marketthat model made decisions that turned out to be less bad than those in the index. To see if this makes sense takes years, multiple market conditions, and many instances of the same experiment running in parallel. The same happens with Nof1 – especially short – and with a more serious and methodical process like that of the CNMV, which was also surrounded by events whose impact on the final result was uncertain. Faced with so many unknowns, the conclusion seems clear: … Read more

Ukraine has tested whether Russia was complying with the ceasefire with an optical illusion in the open field. The video is self-explanatory

by

during the call Christmas Truce In the First World War, enemy soldiers came out of their trenches, exchanged gifts and even played soccer games in no man’s land, in one of the most unusual episodes of the conflict. That scene, as brief as it was unexpected, showed to what extent war can change shape in a matter of hours. A ceasefire on paper. Russia had announced a ceasefire for Orthodox Easter with a strong symbolic and political component, seeking to project an image of negotiating will in the middle of war. However, on the ground the reality has been very different, with thousands of violations recorded in just 32 hours, including artillery attacks, assaults and a massive use of tactical drones. Although long-range attacks were reduced, information arriving from kyiv They point out that the intensity on the near front was maintained, reflecting a dynamic where pauses are used more as a narrative tool than as a true attempt to stop the fighting. The war of stories. Both Moscow and kyiv tried to position themselves as the party that respected the truce, in a conditioned diplomatic pulse also due to international pressure, especially from the United States. While Russia defended having complied with the ceasefire, Ukraine documented thousands of violations in a matter of hours, showing an obvious gap between the official discourse and what was happening on the battlefield. This duality reinforced the idea that truce announcements are part of a communication strategy as much as the war itself. The unexpected test: an optical illusion. In this context, Ukraine decided to go beyond the accusations and designed a direct test to check Russian behavior: evacuate apparently own soldiers, unarmed and wounded, complying with all the conditions of a ceasefire. It turns out that, in reality, it was Russian prisoners in disguise with neutral uniforms, used as a kind of “visual bait” to verify whether the agreements were respected. The scene functioned as a kind of terrifying optical illusion on the battlefield, where what looked like a legitimate evacuation hid a carefully prepared experiment. The video that dismantles the truce. The outcome was so fast as forceful: because a swarm of Russian drones attacked the evacuees, killing several of them without knowing that they were actually their own captured soldiers. The episode, recorded on video and broadcast Later on different social networks, he crudely exposed the fragility of the ceasefire and the inability (or lack of will) to respect it even in situations clearly protected by the rules of war. Beyond the tactical impact, the incident became in a visual test difficult to refute about what was really happening on the front. An episode that also leaves everyone in a bad light due to the crudeness of the visual piece. An impossible truce. If you also want, the set of events confirms that the ceasefire was, in practice, untenable in a conflict where both parties seek to maintain the military initiative while competing for the international narrative. For Russia, the test reveals the extent to which modern combat (based on the intensive use of drones, quick decisions and targets detected without full verification) can turn against him even in sensitive situations. For Ukraine, the test not only highlighted Russian non-compliance, but also showed the extent to which the battle has entered a phase where even humanitarian gestures can become in strategic tools. In this scenario, the truce was nothing more than a nominal pause in a war that continues to develop with the same intensity under a layer of unfulfilled promises.

OpenClaw is the AI ​​agent that is blowing the AI ​​industry’s mind. We have tested it: Crossover 1×42

by

ChatGPT and Claude are great, but they only do things when you ask them to. OpenClaw It’s something else. It is an AI agent that takes advantage of the power of ChatGPT or Claude (or other models) He becomes your personal employee and does everything you ask of himbut in an autonomous and proactive way. This is something that the industry has been promising for years, and although some steps had already been taken in that direction with AIs that, for example, can reserve a table for you in a restaurant, OpenClaw goes a little further because you basically “give them the keys to the office”. So, when you install it on a machine (or a VPS, or a Raspberry Pi, or a Docker container, or wherever you want) you give this AI agent superpowers, because it will be able to do everything it wants on that machine. You will be able to use all the apps you have, browser included, and use all those tools to do things for you. It is, we insist, like having an employee who works for you 24 hours a day and who, if you don’t want to, will never rest. The concept is super powerful, but of course it has some buts. The most important one is security risks, and in this episode we talk about how to protect yourself so that that virtual employee doesn’t end up messing you up and causing chaos. We also have to talk about costs, because this AI agent is a true “token glutton” and you will have to be practical when choosing which models you want to use it with. We talk about all that and many more things in this episode Crossover 1×42, which serves as an introduction to a fascinating topic. Be careful, this is addictive.

has tested its humanoid robot in a real factory (and there is video)

by

For years we have heard the same promise: humanoid robots working side by side with us in factories, warehouses or even in our homes. It’s an idea that appears again and again. However, when we go down from that stage to the ground of a real plant, the story changes quite a bit. There it is not enough to walk or grab objects; everything must happen precisely and be repeated many times without errors. In that context, each small advance begins to have a different meaning. The latest news from Xiaomi. Lei Junfounder, president and CEO, posted a message on his official WeChat account to update the status of the company’s robotics project. The executive explains that a humanoid robot developed by the company has already begun “doing practices” within one of its automobile factories. The manager also links to a published technical article describing the first tests carried out with the robot under factory conditions. Let’s see. What exactly has the robot done in the factory. According to the text, The humanoid robot has been put to the test in a very specific position within the automobile manufacturing process: placing self-tapping nuts on parts of the vehicle’s floor. In practice, the system collects these nuts from an automatic supply equipment and deposits them in the positioning tool where the automated screwing of the position is then carried out. The Chinese firm places this operation in the pressure casting workshop, on ground components after that process. Three figures that help understand the test. Xiaomi explains that the humanoid robot performed this work for three hours of continuous autonomous operation within that position. In that period, it achieved a success rate of 90.2% in the simultaneous placement of the nuts on both sides of the piece, a percentage that the company defines as the number of correct operations compared to the total number of attempts made. Another fact that stands out is the work pace, since the system managed to adjust to a production cycle of up to 76 seconds. This is an important fact because in an industrial line, each operation must fit into very specific times so that the process does not break down. behind the scenes. Xiaomi points out that its humanoid robot is based on the Xiaomi-Robotics-0 model, described as a VLA-type model that integrates vision, language and action within the same system. According to the company, this approach makes it easier for the robot to understand the tasks it must perform, perceive its environment and execute the movements necessary to complete them. The training is also complemented with reinforcement learning, a technique that allows the system to improve its behavior based on the experience accumulated in the physical world. The faults that the robot can find on the line. In its technical description, Xiaomi also points out several scenarios in which the operation may fail. One of the main problems appears during the alignment process between the self-tapping nut and the positioning pin, which must be well centered and seated before screwing can proceed. If this fit is not precise enough, a blockage may occur during the process and the assembly remains incomplete. Additionally, the orientation of the nut inside the robot’s hand can vary with each grip, and the company cites factors that complicate adjustment, such as the knurled structure inside the nut, the magnetic attraction force of the pin, and, in some cases, environmental interference or working angle limitations. The predecessor. To better understand this advance, it is worth remembering that Xiaomi has been exploring the field of humanoid robots for some time. In 2022 the company presented CyberOnea prototype that appeared at one of its events showing basic capabilities such as walking or holding objects. At that time the company itself made it clear that it was a project in an early stage of development. What we see now seems to be situated in another type of scenario: less demonstration on a stage and more tests within a plant, where the objective is to check if these machines can respond to the demands of a repetitive process. Looking to the future. The company also hints that this experiment is just one part of a larger project. Xiaomi points out that it is testing its humanoid robots in various jobs within the factory, including box transport tasks and operations related to the installation of exterior elements of the vehicle. In fact, in his WeChat post, Lei Jun states that the company wants to contribute to the deployment of humanoid robots in smart manufacturing and proposes a medium-term forecast. According to his estimate, in the next five years there could be large quantities of these machines working in his factories.

China has just tested the Fujian with three different aircraft. Electromagnetic catapult is no longer theory, it is practical

by

The cover of an aircraft carrier has always been a tension scenario: each takeoff is a millimeter choreography that combines steel and noise. For more than six decades, that scene was dominated by steam. Now, with him Fujianthat script is also written with electricity. We do not talk about an experiment behind closed doors, but of a public demonstration on deck with several different aircraft, the type of test that records that the electromagnetic catapult is operating in real conditions. The demonstration was not accidental. Coincided with the acts by the 80th Anniversary of Victory in the War against Japan and World War IIwhere prominence also passed through the sea. According to the Ministry of Defensethe Fujian served as a platform for three different models: the J-15T and J-35 and the KJ-600 early alert plane. The three performed cares assisted by catapult and land cable landings, marking a new chapter in their preparation. What was tested. According to Xinhuathe training phase served to check the interaction between the electromagnetic catapult, the braking system and different types of aircraft. The Navy explained that the exercises confirmed the “good compatibility” of the teams and that the Fujian already has the capacity of “full initial deck.” In practice it means that you can organize launch and recovery operations sequenced, preparing the land for a broader integration of its embarked wing. From steam to electromagnetism: For a long time, the steam catapults marked the take -off routine on the aircraft carriers. The EMALS American system introduced a paradigm shift: instead of pressure steam, it uses accumulated electric power and converted into a launch force. It is already installed in the USS Gerald R. Ford (CVN-78), first aircraft carrier to incorporate it. The US Navy ensures that It offers greater acceleration control, less wear on airplanes and cover and ability to boost light drones to heavy fighters. The transition reduces maintenance and opens the operational range. Three aircraft, three mission. The J-15T is the evolution of a veteran naval hunting, adapted to operate with catapults. Its role is to ensure the continuity of the aviation embarked while more advanced models arrive. The J-35, on the other hand, represents the jump to the fifth generation: a furtive hunt with greater scope and modern sensors. The KJ-600 trio completes, an early alert plane designed to expand the combat group and coordinate operations to hundreds of kilometers. Where is the Fujian today. The aircraft carrier began its sea tests in May 2024 and, since then, it has followed a progressive calendar. Systems and stability check settings have been made, while rehearsing cover operations. The latest exercises show that the ship has an initial capacity to operate with different aircraft, but has not yet reached the level of full operability required by an aeronaval group in long -range missions. Only two with Catapult EM. To date, only two armed ones have managed to integrate electromagnetic catapults into service aircraft carriers. As we point out above, the United States operates electromagnetic catapults in the Gerald R. Ford and China class has demonstrated its operation in the Fujian. These experiences place both armed in a high technological category, while the rest of the countries continue to use steam systems or lack catapults. It is a milestone that reflects the investment and industrial development scale necessary to get here. What changes on deck. Electromagnetic catapult opens a range of possibilities that were previously more limited. It allows drones or light aircraft with the same security as a great tonnage, and does so with less vibration and mechanical stress. For the crew, the work environment is quieter and less hot. In practice, it means that the aircraft carriers can sustain a greater number of daily exits with less maintenance between operations. Of the test at the service. The maneuvers carried out this month do not yet equate to have a fully operational aircraft carrier. The Fujian is still in an early phase: he needs to accumulate many more hours of sea and certify maneuvers in diverse conditions before being able to hold a embedded wing in the campaign. The Ministry of Defense speaks of a milestone, but also recognizes that it is missing. The transition from the demonstration to real capacity will be gradual and will depend on how systems respond in more demanding scenarios. The Fujian has gone from being a project wrapped in speculation to an aircraft carrier that shows on deck how its electromagnetic catapult works. The achieved this month is a visible milestone, although still partial. China thus enters a small club in which each electric takeoff is much more than a technical gesture: it is a declaration of intentions. The future will say how long it takes to convert these maneuvers into the routine of a fleet capable of operating with continuity on the high seas.

All under the watchful eye and comments of your partner Angela Blanco. The question is inevitable: will it get it? A trip to counterreloj: leave the house under technological control before going on a trip One of the strengths that Ana of smart feeders stands most is their ability to weigh the exact ration of feed. A key detail for those who live with several pets that do not eat the same. “The right -wing feeder is always that of the cat and the one on the left that of the cat. So this work we have done. Now it is simply that they get used to this what gives them eating every x hours,” he explains. Everything painted well after Unboxing. Remove them from the box, configure them in the living room and then take them to their final place.

In the other it has worked.” The typical situation in which you are convinced of having followed the manual to the letter and still something fails. Luckily, the solution was close. The action then moved to the terrace. On paper, installing the movement sensor seemed simple. In practice, not so much. “What happens is that it needs food and I only have one plug Here on the terrace that is here behind the column, ”Ana details. Relocating it was an option, although it was not simple either.” A lot of people passes here, especially in summer, and we will have to limit very well the Mapita of this sensor so that it does not give us or false positives and it works well. “I had to check if the system responded as it should.

A Chinese program has tested the safety levels of Chinese cars. He has evidenced Chinese cars

by

China has received a blow of reality. This is Kyle Chan’s opinionexpert in Chinese industry, who summarizes the position of Tesla on the rest of the Chinese companies in terms of safety of their ADAS systems. The Tweet is motivated by a Chinese program that has faced 36 cars to the same exam to check how 15 obstacles were solved. The result: 216 accidents and a much higher position of Tesla. So superior that Elon Musk’s cars have not only obtained the highest score, they are also the only ones who have successfully solved five of the six major scenarios under which the tests were encompassed. But, in addition to all this, there are many other interesting diatribes. All tests were published on television since they were carried out by the media DonGchedi. It is not just a sample of the lack of Chinese cars is also a touch of attention to their own manufacturers. Frightful results China is living a revolution in the car market. There is no doubt about that. They have electric cars with the highest technological load in the world and live in a competitive bubble so strong that it threatensLeave multiple brands aheadwith the most settled by launching a Aggressive Price War. But in addition to having the car equipped with the fastest electric charge or the best incorporated drone, Chinese manufacturers They have been presuming exceptional autonomous driving capabilities. In fact, ourselves in Xataka We have been able to check firsthand how a car of less than 10,000 euros to direct change, such as Byd Seagullcan move with total ease with the famous Eye of God less advanced. Despite this, the Chinese government has been launching messages to manufacturers warning them that they cannot sell promises that they cannot meet later. That is why he has imposed fines to those who offer their products showing videos or presuming an advanced autonomous driving that then has many asterisks. It is one of the reasons why Autonomous driving was the great absent In the last presentation of Xiaomi Yu7. And the ears pull has finished exemplifying the tests performed by the Chinese media DonGchediwhose video and a half video It can also be seen on YouTube. It shows the examination that 36 cars have passed, the vast majority of them Chinese cars, who have faced 15 risk situations encompassed in six large groups. The result has been fateful. The Chinese car with the best score has been the GWM Wey Lanshan, obtaining the third best score and saving furniture in three of the six large groups. Specifically, he acted correctly avoiding an accident when he found an unexpected obstacle on the road, with the appearance of trucks in works areas or when a second vehicle appeared completely detained by surprise. He suspended with the appearance of other obstacles in works areas, when a second vehicle cut his trajectory aggressively or with the appearance of a wild animal. Similar results (exceeding three of the six scenarios) have also been obtained by the XPEng G6, Aito M9, Luxeed R7 and De denza Z9 GT EV, from better to worse score. Below, all the remaining cars (29 of 36) have not solved more than two risk situations. And of those 29 suspended cars, another 15 have failed to overcome even one of the proposed scenarios. Some, in fact, have only faced four risk situations because they lacked the necessary equipment to face these tests. The Mercedes Class C and the Volkswagen Passat are among these 15 cars that have failed to overcome a single test. But there are surprises among the suspended. The eighth classified is the Aion RT, a Chinese car that has not managed to overcome more than two tests. Just ahead of TOYOTA BZ3Xthe next non -Chinese car (With its nuances) that is in the test and that next to Tesla is the only one that sneaks among the 10 best. If we can talk about “the best” for cars that have not exceeded four of the six proposed tests. They are cars that, despite everything, have been better classified than the Xiaomi Su7 (and also that its ultra version, which has obtained worse results yet), six byd cars (both under the firm byd and some of its luxury brands) or those expected in Europe, the leapmotor C10 and the XPEng P7 (which are sold in Europe) or the expected Zeekr 001O EV. You can see all the list in Carnewschina. A good ear pull The publication of the evidence is not accidental and is especially relevant. In the post with which we opened this article, Kyle Chan highlighted that Tesla is living her own “Chatgpt moment”. The company It has been criticized by Do not include lidar radars in their cars that should improve their performance. However, it has proven to be ahead of all its competitors. The Tesla Model 3 and Model and They are the only ones who have achieved Save successfully almost all tests. The electric Berlina only suspended when faced with the appearance of a wild animal while model and did overcome this problem but acted in an inconvenient way in the scenarios in works. In spite of everything, Chan defends on his tweet that the results highlight the true situation of Chinese technology, although manufacturers try to demonstrate that they are much more advanced. For Chan, that the tests were broadcast on television are a clear government call to the manufacturers, something that begins to be common after an accident of an Xiaomi SU7 that had activated the ADAS systems for semi -automatic driving was recorded. Hu Xijin, former newspaper editor Global Timeswhich is dependent on the Chinese Communist Party and, therefore, it is understood that it is an extension of the government’s communications, pointed out That the results of the tests were good for local manufacturers because they position them where they really are. Understand that it is a good time for Chinese brands to learn what Elon … Read more
