What happens when its creator creates them biased

by

Elon Musk has always defined itself as An “absolutist” of freedom of expression. Precisely one of the objectives when he bought Twitter was to turn it into a “public square” in which to talk about everything without tap. It seems that he is achieving it, but now he goes further. Now we want us to believe that Grok 3 will always tell us the truth. Politically incorrect. According to him, Grok 3 “is an AI that seeks the truth to the fullest, although sometimes that truth is at odds with the politically correct.” As they point out In TechCrunchhe said it yesterday during the presentation of this new family of AI models. Of censorship, little or nothing. Grok’s previous versions have already demonstrated a tendency to have a tone and “psychology” different from that of their competitors. The first version was especially striking for its sarcastic toneand with Grok 2 things got especially interesting In the field of censorship. Above all, because it did not exist, and for example it is possible Generate Deepfakes of famous characters Without any problem from any X. Grok 3 and the problem of meaning the truth. Musk’s promises in this regard are striking, but hardly realizable. The reason is simple: that the absolute truths exist is already the object of debate in itself, but there is a powerful argument against: the truths are usually relative and depend on the context or point of view. The facts are there, but their interpretation is absolutely variable and is subject to biases. Humans, yes, but afterwards, also from AI. A neutral AI? Grok 3 seems to want to aspire to become a neutral the AI ​​that gets to the facts and that tells us the truth. Here an element in favor of these models is that lately they cite the sources on which they are based to give their answers. For example, perplexity, and that helps we can contrast those answers. OpenAI is (a little) left. 2003 studies They detected that models of AI like chatgpt had certain biases and seemed to position themselves more towards those who support the protection of the environment, towards libertarian ideologies and towards political lefties. Gemini, Google’s model, was criticized for creating “woke” images of viking or black Nazis, for example. Grok 3 could “talk” like Donald Trump. That an AI is politically incorrect makes us wait for unique responses. Dan Hendrycks, director of the Center for Ai Safety and director of Xai has raised How an AI model could respond as Donald Trump does. Direct, without ambiguity and without taking into account the politically correct. That can be irritating, but it would also allow unpopular opinions and controversial points of view. It was biases, for better and worse. Of course, theoretically without violating social norms and ethical principles, such as XAI explains in his “framework for risk management”. Partisan models. He Hendricks study He evaluated with what US politician models such as GPT-4O, Grok, or call 3.3 were more aligned, and according to their tests everyone seemed to be closer to Biden’s vision than Trump’s, Kamala Harris, or Bernie Sanders. It develops the idea of ​​what calls a “citizen assembly” in which EUU census data on political issues would be collected and then use those answers and modify the values ​​of a LLM Open Source. At this time that model would have values ​​that would be closer to those of Trump than to Biden, for example. But. The truth is that Grok had to be updated last August precisely not to say the truth. Five Secretaries of State in the US They warned that this chatbot was spreading misinformation when users asked about information about the then imminent elections. The change did not affect Grok’s ability to Generate Deepfakes Of the candidates, although in September 2023 x eliminated The capacity of some users to republicate electoral misinformation. Training is key. The AI ​​learns from those data that we provide in the training process, so the biases that an AI may have will have their origin in that data. If we train AI with data that profile your answers to a certain ideological current and criticize another, the theoretically replicate that position in your speech. No details have been given about how Grok 3 has trained and it is possible that we never know it, but if Xai wants us “Adjust” your perspectives and biases. In Xataka | X has been filled with very strange photos of celebrities. The culprit is Grok, which has no limits in its creation of images

They were nuclear weapons experts

by

The Government Efficiency Department (Doge) led by Elon Musk does not supply say goodbye to all officials That, according to the greatest fortune of the planet, there are plenty of administration. In his last intervention, the Doge agents They fired about 350 officials of the Department of Energy. What they did not know is that they were sending specialists at home nuclear eyelet assembly and control of weapons and nuclear waste. Nuclear layoffs. According to published CBS News, Doge employees thought that last Thursday they were saying employees in the test period or simple administrative department of the Department of Energy, without stopping to ask what their work really was. However, hundreds of federal employees who work in the United States nuclear weapons programs also received their dismissal notification. According to sources of The Associated Press Near to the Department of Energy, up to 350 employees of the National Nuclear Safety Administration (NNSA) were dismissed unexpectedly. Some of them lost access to their email before being formally notified or could not access their job with their credentials. The NSA is the entity responsible for managing the country’s nuclear weapons, among other crucial responsibilities. Specialists in nuclear eyelets. One of the facilities most affected by Doge’s layoffs was the Pantex plant, near Yellow (Texas), which suffered a 30% template cut without prior notice. In this plant, employees are dedicated to the reensamblage of nuclear eyelets, a high specialization task that requires the highest levels of security authorization. The agency’s interim director, Teresa Robbins, sent a statement to the dismissed employees annuling the dismissal order, has caused enormous confusion throughout the agency. However, 28 officials were not readmitted. “This letter serves as a formal notification that the termination decision issued on February 13, 2025 has been terminated, with an immediate effect,” said the memorandum obtained by AP. Dismiss first, then ask. Given the nature of these dismissals, the discretion used by the department led by Elon Musk, when saying goodbye to officials without previously analyzing the scope of their work, has been revealed. That action pattern carries the Elon Musk’s unequivocal seal. He did it With the Development Department of the Tesla Supercores, and then hire them again because the service had been paralyzed. He did the same With the Twitter moderation department Chaos in a strategic department. “The people of Doge arrive without having the slightest idea of ​​what are the responsibilities of these departments. They do not seem to realize that, in reality, it is more about the department of nuclear weapons than the department of energy,” said Daryl Kimball, Executive Director of the Arms Control Association. A senior NSA official, Rob Plonski, also expressed concern about dismissals in a LinkedIn publication: “This is a crucial moment. We must decide whether we are truly committed to leading on the world stage or if we content to undermine the same systems that ensure the future of our nation.” Plonski warned that “cutting the federal workforce responsible for these functions can be seen as reckless in the best and adversely opportunistic in the worst.” CONSEQUENCES FOR THE NUCTILE FORCE OF US. The layoffs and subsequent readmission of the employees of the Department of Energy have planted the seed of uncertainty among those officials, and some are rethinking whether to work back in the agency. “The main impact was a blow to the morals and trust of the employees who were dismissed,” assured to CNN A nearby source. Many of them have dedicated their entire career to nuclear programs, becoming a valuable asset of knowledge in this area. These layoffs have only come to aggravate the constant loss they had already suffered after a recent wave of retirement, which has already meant a loss of qualified talent in this department, just when the US is carrying out an important effort of Modernization of nuclear weapons of 750,000 million dollars. Edwin LymanDirector of Nuclear Energy Security of the Union of Concertned Scientists (UCS), explained to CBS News that layoffs could “alter the daily functioning of the agency and create a sense of instability about the nuclear program both in the US and abroad. That can only benefit the adversaries of this country.” In Xataka | A government “Extremely Hardcore”: Elon Musk is applying to the US the same recipe that has applied to all its companies Image | ThE White HouseUnited States Department of Defense

We have discovered (again) the secret of Roman concrete. Is less impressive than it seems

by

It does not fail. It seems mathematical. From time to time, the world rediscovers the Roman concrete and hallucin with the durability of a material that allows the Pantheon of Agrippa to have 2,000 years standing (while modern concrete cracks within a few decades). Incidentally, almost with the same regularity, there is some scientist or engineer who claims to have found the key secret that this is. The last occasion He has touched the Massachusetts Technological Institute And, as usual, the story is not exactly what it seems. What does the study say? MIT researchers They have studied Small pieces of lime that are usually found in Roman concrete: the ‘calcium oxide’ clasts. These types of structures have been studied a lot in romas infrastructure located in maritime contexts and, for years, has been related to some “self -regime” capacity of the material. Understanding what it means. According to some scientiststhe water that would enter through the concrete cracks would drag the calcium ions of the Classos in a process that would end up calcitating and sealing the cracks. The work of the MIT of recent days, also studies those clasts in the terrestrial concrete and theorizes that they are the result of the Romans added living lime to the mixture of the concrete (instead of the dull lime – calcium hydroxide – key of the Puzolenic reactions). Beyond that, researchers They made several mixtures With living lime and verified that, according to their theory, in these new mixtures lime clasts were generated (and was calcited that repaired the cracks). As Brian Potter saysthe discovery is interesting at the historical level. But, despite the attempts to sell it as something revolutionary, it is potentially useless. Useless? Yes, useless. When talking about Roman concrete, a lot of mistakes are usually made, but there are two recurring: the first, As Manuel F. Herrador always reminds usStructural concrete professor at the University School of the University of Coruña, is “the survivor’s bias.” The idea of ​​the extraordinary quality of Roman concrete comes from studying, precisely, the best structures they did, which have best been preserved. On the other hand, most of what the Romans built has already disappeared completely and cannot be studied. The second error. We are comparing ‘churras with merinas’ at a functional level. For being clear, with the Roman concrete we could not make a tenth of the things we do with modern concrete. The clearest example is reinforced concrete (that is, the mixture of concrete with reinforcement steel). These materials allow us to solve many of the structural problems presented , We have to pay a cost. The most obvious: the structures run before. We make the concrete we want to do. This is perhaps the most important to consider when we talk about Roman concrete: we do not “concrete to the Roman” because we do not want; Because it is not worth what we want to get. The same potter It puts examples (the Hindu temples and Buddhists built to “last more than 1000 years”) that show that current science and technology allow authentic virguerías. The question is if we want to do them in a world that changes so quickly and not, no matter how much we like the Romans, we do not want. Luckily: that allows us to go much further.

The best headphones to do sports I have tried are also very exclusive

by

The headphones Open Ear Or open construction are increasingly fashionable. The new honor proposal, its earbuds Open, come to make a foothold with A quite interesting bet that artificial intelligence by flag has. I am a person who has spent almost all his life looking for an open headset with which he was comfortable and, until they have fallen into my hands, I have not found any. I have been several weeks with them daily and giving them a lot of cane in almost any scenario: either working, listening to podcast or exercising. The honor commitment has a lot to tell And this has been our experience with her. Are expensive headphones always better than economic? Earbuds Open Honor Technical Card Honor Earbuds Open Dimensions and weight Headphones: 49.22 x 39.52 x 15.6 mm – 7.9 grams Case: 80.44 x 61.02 x 20.45 mm – 52.5 grams Diaphragm unit Dynamic 16 mm multimagnetic circuit driver Noise cancellation Cancellation of active noise CALL CANCELLATION Battery Headphones: 58 mAh Box: 480 mAh connection Bluetooth 5.2 compatibility Android, iOS Extras 3x microphones IP54 resistance on headphones Equalizer Pressure controls Sliding controls Simultaneous dual connection Proximity sensor USB-C load price 149 euros * Some price may have changed from the last review Honor Earbuds Open, our experience A design to get used to. I have never been very fan of headphones that have some type of ear support (hence it has never been comfortable with headphones Open Ear) and the first contact with these of honor is somewhat strange. Put them on is quite simple, although not so much adjust them to the auditory channel. Interestingly, in my case, it cost me to accommodate the headset in the left ear (not on the right). A matter of a couple of times alone. The Earbuds Open of Honor are available in two colors: a gold version called ‘Polar’ and others in a black sober, which has been the unit analyzed. The design is striking and the very sober color, which gives rise to a headset that attracts attention, but not too much. Each unit is divided into three differentiated segments, being the silicone that adapts to the ear the main element. This, of food quality, is quite soft to the touch and comfortable (it also helps the headphones do not weigh too much, 7.9 grams). You put them on and forget that you are wearing them, especially playing sports. I have tried them in several different scenarios And there are two where I have felt especially comfortable with them: running down the street and in the gym. There, having that open character, is where they shine the most. I would like to score with respect to silicone rings. Honor explains that its design is compatible with glasses, thanks to the materials and its ultrafine design. On the street or playing sports, I don’t wear glasses, but I do use when I work. In that scenario and, for a while, there is no problem, but the thing changes in long sessions. Nothing painful or alarming, but there is a small feeling of ‘heaviness’ in the ear that is not liked by the whole world. The case. Honor has worked very well when building a case that, both in sight and touch, feels prémicium on all sides. It is plastic, but like everything else, there are plastics and plastics. Both the upper and the lower part have a rough texture that mimics the leather and that personally I think it feels like a glove. The headphones are ‘burned’ inside it, which makes it an elongated, but very fine case. Come on, ideal to wear in your pocket. As soon as it weighs 52.5 grams, it has a USB-C port to load it (and, eye, because they have no wireless load) and has a button inside to synchronize them with any device. To put a little ‘but’, I am worried that the case will resell if we take it next to some keys or something that can scratch it; However, otherwise, I think it complies (and with note) with its mission. Many functions, too many exclusive. Beyond the design, its open structure and a noise cancellation that we will talk about later, one of the key points of these honor Earbuds Pro is in the translation by AI. It seems very interesting that the brand wants to work with these tools, since thanks to them the barriers of the language can disappear completely. What stands out most of these is the so -called ‘shared mode’. Thanks to it, we can give up a headset to another person and have a real -time translation into two ways. We can also put the two headphones ourselves and let the phone be our personal translator or even use them to translate a conference or video, for example. What is the problem? That these functions are exclusive to the Magic7 Pro and the Magic 7 RSR Porsche Design, which obviously restricts users who can access them. Honor explains that these functions will reach its AI Space application, which is available in Google Play Store and App Store and thanks to which we can configure them. This application is what we will have to match and configure certain aspects of the headphones. What stands out most of it is in four points: noise cancellation, equalizer mode, direct accesses and double connection, without a doubt what I liked most at the level of use. It is very useful if we want to use them on a portable console like a Steam Deckbut receive mobile calls without playing anything. It is also appreciated that honor allows us to configure the way we interact with the headphones. The Earbuds Open do not invent the wheel, since we can either press a certain number of times (two or three), keep pressed or slide up or down for the volume. Some more customization would be good in this regard, but I think it is enough for most … Read more

The OnePlus path in the world of smartwatches has been the most interesting. After A first approach that left mixed sensations, the company climbed into the wear os car with a OnePlus 2 that he liked a lot and that he went straight to the Top watches with the Google operating system. His proposal consisted of a premium watch, a double processor architecture and a really good experience. With his new smartwatch, the OnePlus Watch 3the company wants to go one step further. And it is that the OnePlus Watch 3 retains many of the things that liked the previous model, but has been updated with some interesting novelties such as a digital crown, new measurements, a better interpretation of them and more battery. All this at a similar price, although somewhat higher, to its launch predecessor. Made the presentations, we will know it better. OnePlus Watch 3 Technical Card OnePlus Watch 3 dimensions and weight 46.6 x 47.6 x 11.75 mm 49.7 grams without a strap 81 grams with strap screen Amoled Ltpo of 1.5 inches Crystal Zafiro 2.5D Pico brightness: 2,200 nits Refresco rate: 60 Hz Always On Display mode processor High performance: Snapdragon W5 Efficiency: Bes2800 mcu RAM N/D Internal storage 32 GB Sensors Optical heart rate sensor SPO2 Accelerometer Gyroscope Electronic compass Barometer Environmental light sensor All-in-one button GeoPositioning Integrated GPS chip (L1+L5) GNSS battery 631 mAh Fast charge endurance A thousand STD-810H IP68 5ATM connectivity Bluetooth 5.2 WIFI 2,4/5 GHz NFC Operating system Wear os 5 Rtos others Electrocardiogram More than 100 sports modes 11 Professional Sports Modes Bluetooth calls NFC and payments from the clock Stainless steel frame Videos control Camera remote control Health check in 60 seconds price 349 euros A refined design Image | OnePlus OnePlus has renewed its clock and now the crown has a more hexagonal appearance, with a side area that houses a button and A crown that, this time, broken. The crown has a conical design, is textured and can be clip and turn. The OnePlus Watch 2 also had a crown, but only admitted pulsations. The clock bezels are made of titanium alloy, while the box is made of stainless steel. With regard to the front, OnePlus has managed to take better advantage of the frames and has mounted a 1.5 -inch AMOLED LTPO panel. The screen is made of the same material as the OnePlus 13reaching a peak shine up to 2,200 nitsall protected by a 2D sapphire crystal. Speaking of protections, the clock has been manufactured according to the MIL-STD-810AH military standard, it has IP68 certification and endure up to 5 ATM. Come on, he is not afraid of water. The two processors come back Image | OnePlus Under the hood, the device again bet on a double processor architecture: a Snapdragon W5 of Qualcomm for the most demanding tasks of Y a Bes2800 MCU for the most basic tasks. According to OnePlus, this new BES2800 processor improves the CPU in 200% and the NPU in 400%. We also have two operating systems: Wear os 5 (Powerful and complete) and a (simpler and efficient) rtos that alternate depending on energy configuration. Not only have the main components be updated, but also the sensory. To the heart rhythm sensors and SPO2, whose materials have been improved, OnePlus has added a doll temperature sensor. In addition, the company has improved the design of the sensor module, so that there is less distance between the LED and the photodetector and the impact of outside light is reduced.

It is still one of the highest autonomies in the market, although everything will depend on the use we make of the clock. It should be noted that the clock incorporates fast charging and that in just 10 minutes it offers up to a whole day of autonomy, according to the brand. The operating system is Wear OS 5, so it has access to Google Play, Google Wallet to pay and the entire Google ecosystem. In the case of having a OnePlus smartphone, it will also be possible smartwatch screen). Health and Sports Improvements Image | OnePlus The firm has also improved how metrics are taught, giving more cohesion to all the information in the form of “360 body and mind”, a new app that, in essence, processes all the information collected by the clock and digest it to give us a global metricunderstandable and based on patterns. This is something that we have already seen in many other wearables of other brands and that now reaches the OnePlus clock. But the most juicy novelty is that, finely, OnePlus has managed to implement the electrocardiogram. Thanks to the sensor located in the “Everything in one” button (the lower one, the one that is not the crown) we can make an electrocardiogram in 30 seconds and measure our vascular health AKA the arterial rigidity. Not only that, but In 60 seconds we can make us a “medical check -up” which measures the pulsations, vascular age, the level of oxygen in blood,. Mental well -being, sleep quality and skin temperature. Image | OnePlus Or it will, rather, because neither the electrocardiogram nor this check in 60 seconds will be available. They are pending approval by the organisms and is expected to arrive in the second quarter of 2025. Finally, and in the face of the most athletes, the clock is able to analyze More than 100 sports modes and includes 11 professional ways to obtain more detailed metrics. One of them is, how could it be otherwise, running. And in that sense, note that the firm has improved the GPS chip and implemented a double band chip that should improve tracking even in more complex places.

Japan will copy Venice to stop mass tourism. Two levels of transport price: the tourist pays more

by

Exactly one week there was a stir for the decision that Venice had adopted to stop mass tourism. It was an update of a measure that took months ago: an entry rate for the tourist, which was now going to duplicate In view of the good results he had given to public coffers. Japan had already “flirted” with something similar with A double pricing system in menus. Now Kyoto wants to go further with public transport. First was the menu. As we said, last summer the nation hospitality saw an opportunity before the massive arrival of tourists. Japan’s restaurant industry implemented A two -level price system in the most tourist places in the nation. You don’t have to be very lynx to understand it: restaurants seek to take advantage of the influx of foreign visitors, a strategy where it is also not scare to local customers. Behind this price increase there was something as evident as purchasing power. Restoration companies were or more towards tourists because, in essence, they are willing to pay more. Miki Watanabe, president of the important Watami restaurant chain, I explained it that way: “The Japanese do not buy 3,000 yen sirloin skewers, but tourists who arrive in Japan say it is cheap and buy them.” The thing now is different. The news today takes us to Kyoto, the former capital of Japan. They want Implement a system of differentiated rates in public transportbecoming the first city in the country to adopt this measure to manage the growing number of foreign visitors. Mayor Koji Matsui has proposed that Tourists pay a higher rate on buses operated by the city compared to local residents, with the aim of generating funds to mitigate congestion and preserve cultural heritage. Living with mass tourism. We have told it countless times. From the reopening of borders after the pandemic and with a weak yen that favors the spending of tourists, Kyoto and many others Japanese cities have experienced a massive influx of tourists. In 2024, the city, which has 1.5 million inhabitants, received seven million international tourists, which has generated concerns about its impact on everyday life. This phenomenon is part of a broader trend in Japan, than In 2024 he reached a record of 36 million foreign visitorswith a total expense that exceeded 8 billion yen. The negative effects of mass tourism in the city include Aglomerations in public transport, garbage in the streets and cultural conflicts. In fact, some residents have reported difficulties in accessing buses due to excess passengers, which especially affects students and people who need to move to hospitals. Proposed measures. To counteract these problems, the Kyoto authorities have promoted several initiatives, including, The commented differentiated rate in urban buseswhere tourists would pay more than residents, allowing funds to improve infrastructure and reduce the impact of tourism. In addition, the administration also plans An increase in accommodation tax for those who stay in hotels in the city or the creation of exclusive buses for touristswith routes to the main tourist sites, thus relieving the pressure on public transport used by the premises. Moreover. There is also talk of the Distribution of awareness brochures to educate visitors/tourists about the rules of Japanese behavior and cultural sensibilities. In this regard, Mayor Matsui has emphasized that these measures seek to balance the daily life of residents with the tourist influx, ensuring that the local community also receives benefits of tourism activity. Other examples. In this way, Japan joins other enclaves such as The commented in Venice. The truth is that from a while to this part, the so -called differentiated tarification has already been implemented or will do so in other places. For example, in Himeji, Japan, It was proposed to raise the entrance fee to Himeji Castle for not residentsParis plans Apply higher rates at the Louvre Museum For visitors outside the EU, and in India it has been applied Differentiated rates in emblematic monuments such as Taj Mahalwith higher prices for foreign tourists. All initiatives that seek a balance between the promotion of tourism and the preservation of heritage and the quality of life of the residents. A cultural problem. It is the last of the legs to be treated in the nation and its tourist boom. Beyond the quantitative theme and logistics impact, mass tourism In Japan it has also generated cultural conflicts. In Kyoto, and due to the inappropriate behaviors of tourists, Mayor Matsui has pointed out some “tips” to take into accountsuch as eating while walking through the streets, which is considered of bad education in Japanese culture. In addition, Matsui also recalled that making strong noises in sanctuaries and other sacred spaces, chasing the geishas to take photographs without permission or entering tea houses without prior reserve, interrupting their traditional functioning, it is everything but educated for the nation. Plus: The geographical design of the city, surrounded by mountains and with narrow streets in its historic center, aggravates these problems, making the city particularly sensitive to tourist saturation. The future of tourism. That said, and despite the difficulties, Kyoto says he remains committed to receiving tourists and sharing his cultural and historical wealth. However, the local administration works to ensure that this growth is managed sustainably. Matsui reaffirms that these initiatives do not seek to restrict tourism, but to administer it efficiently and respectfully with the community and the environment. The proposal of differentiated rates is part of a two -year planwhich must still be approved by the City Council. If implemented, Kyoto would mark a precedent in Japan and could influence other regions that face similar problems with mass tourism. Image | Robert Thomson In Xataka | Visitors do not stop arriving.

Huawei already has its first open headphones with hook: so are the frearchc Huawei is presenting globally. He has put a price at his most exclusive mobile, the Mate XT Ultimate (a triple folding of 3,499 euros), has presented his Huawei Band 10 And, next to her, her first open headphones with hook. The Huawei Forearc have a rather groundbreaking design, with the classic sports headphones hook implemented in headphones with calling noise in calls. This is all that should know about them. Huawei Forearc Technical Card Huawei Forearc Dimensions and weight of the headphones 45.4 x 18.35 x 47.5 mm / 8.9 g Dimensions and load base weight 67.8 x 67.8 x 26.5 mm / 67 g SOUND High sensitivity driver 17 x 12 mm Noise cancellation (ANC) No Audio codecs SBC, AAC Microphones Dual microphone battery Up to 28 hours of playback (case) Up to 7 hours of playback (headphones) Load per USB-C connectivity Bluetooth 5.2 compatibility iOS and Android design IP57 price 119 euros A breaking design by and for athletes The main characteristic that differentiates these headphones regarding their competition is design. The Forearc have a Open Hook Formatdesigned to adjust as safely as possible even if we are practicing sports. They are covered with liquid silicone to be soft, with alloy nickel-dotanium (NITI) inside to guarantee maximum durability. Speaking of this, they are Water resistant by IP57 protocoland their microphones are specially designed to resist water (sweat and rain) during our sports practice. One of the main characteristics of the open format is that it is not compatible with active noise cancellation. This is done on purpose, not to isolate ourselves from outside sound while we are practicing sports. Despite this, the quality of the serious ones, the sharpness of calls through AI, and the sound capture of the microphones, which they have have have Cancellation of calls. Regarding its autonomy, Huawei promises 28 hours of listening by helping us with the case and 7 hours only with the headphones. They have fast charging, with three hours of listening in just 10 minutes. Of course, the controls are tactile, with double touch gestures, triple touch, long pulsation and short pulsation. Price and availability of the Huawei Forearc The Huawei Forearc are priced at 119 euros, and will be available globally. At the moment, there is no official date for its arrival in Spain.

The ghost of drought

by

A few days ago we talked about how a corridor had opened between the Azores anticyclone and Iceland depression. Moreover, we argued how Spain had many options for become the great beneficiary of that trough. Well, we sin of optimists. Just look at heaven to realize that this is never to end. What happened? In the next few days, there are two structures that walk the time of the peninsula. On the one hand, a cold front has been slowly moving through the west of the Iberian Peninsula. On the other, a Dana has traveled the south coast from the Gulf of Cádiz to the heart of Algeria. As the meteorologist Ángel Rivera explainedwhat we see is the result of the closure of that wide historical trough. And it will happen again. Right now, there is an “extensive cold storm” in the Atlantic corridorbut it doesn’t seem to affect us. Because just southwest of this, a dorsal begins to gain strength and will end up moving towards Europe. And all that without counting the anticyclonic wall that is beginning to develop between the Canary Islands and the mouth of the Cantabrian; and that, as a direct consequence, it will generate a Dana that will cross the Gulf of Cádiz and (as far as we can predict) will also go to North Africa. That is, again and again, the chances of rain arriving in Spain are frustrated. What he said: the never ending story. What time will it do? Aemet’s forecast is very clear. From Monday to Wednesday, the most important thing will happen in the Canary Islands: with very strong wind gusts and notices. Galicia can also suffer some timing, but the rest of the peninsula will only see some occasional showers. On Thursday it will be a sunny day and during the weekend we will see how that front of which we have spoken will sweep the peninsula leaving some rain. On Sunday the sun will return. In general, temperatures will be more of spring. And that is the problem. We already carry two warm winters (No cold waves or intense cold episodes) And the rain is being as erratic as usual. That places us in a complex situation: before we realize, the drought will be knocking on our door. The best example is The Sau reservoir, in Barcelona: A swamp that “despite the latest rains (…) shows a lousy state, with just 8% of its water flow.” It is a notice to navigators: the Ter-Llobregat system, the Segura basin or the Andalusian Mediterranean basins They are already having a bad time. The good weather is, deep down, a conviction. Spring for today, but thirst for tomorrow.

Temu and Shein are already being overcome by the next Chinese trade giant: Tiktok

by

Tiktok has achieved in just one year what seemed impossible: to overcome sales to Shein and Temu in the US market, consolidating itself as the new power of Chinese electronic commerce, according to reports Bloomberg Citing Second Measure data, its transactional analytical tool. Their sales fired 153% in January, compared to the modest compared 26% of Shein and 28% of Temu. Between the lines. Tiktok Shop is taking more market to Shein that a Temu. In purchases greater than 25 dollars it has earned 16 quota points, while in the lower only 7. That is, it is having more success by selling medium -price products than Chollitos. The threat. This ascent can be seen truncated by several fronts: The contrast. While Tiktok Shop accelerates, its Chinese competitors suffer: In perspective. With 170 million monthly active users in the US, Tiktok has shown that its ability to monetize its user base goes beyond advertising.
