records

Someone records them without warning and nobody knows what to do

by

There is an awkward moment that is becoming common in meetings, face -to -face or online: someone enters the meeting, opens the laptop and without saying anything activates your Bot of ia To record and transcribe. The rest is silent, calibrating whether to protest or pretend that nothing happens. Thinking if you have enough hierarchy to raise your voice or if you will pay. Welcome to the era of normalized corporate surveillance. As usually happens, Technology has arrived before the rules. IA attendees can record, transcribeanalyze the tone, identify who speaks more, make inferences about us and even suggest answers in real time. But nobody knows what to do with that socially. Is it bad education to activate a Bot without warning? Where are that data? Who else will know them? What are they going to process with them? Is The classic paradox of all technological disruption: The tool exists, it works, promises efficiency, but the social norms are three steps behind. As when the mobiles arrived and it took years to decide whether it was acceptable to answer in the cinema or speak in the elevator. With the finish line we are living something similar. Only This time the risks are greater. Because the Bot Not only record: interpret, analyze, store. You can capture not only what you say, but how you say it, when you doubt, who you are more or less agree. And all that is registered in the other party, but also in servers of companies that already know too much about us. The solution will not come from technology, but from us. We need to quickly develop a clear label: Notify before recording or inviting the Bot. Specify what information will be used for. Ask if someone feels uncomfortable. Normalize company policies that restrict them, at least those of certain types. If we do not, We will end up normalizing that any conversation can become data to treat Without our consent. And that is not a meeting we want to attend. In Xataka | If the question is what recruiters are set when hiring, a study has given the answer: experience and attitude Outstanding image | Xataka

The German Wendelstein 7-X reactor has broken all records

by

In the field of nuclear fusion ITER (International Thermonuclear Experctor reactor), The experimental reactor that an international consortium led by Europe is building in the French town of Cadarache, monopolizes all eyes. However, in the old continent we have other fusion energy machines that are also very important. The Wendelstein 7-X experimental reactorwhich is installed in one of the buildings that the Max Planck Institute has for Plasma Physics in Greifswald (Germany), is one of them. Its purpose is to contribute to the development of the technologies involved in the tuning of nuclear fusion reactors through magnetic confinement, but its formula is different from that proposed by Iter or JET. In fact, the Wendelstein 7-X reactor is a type design Stellarator. The most obvious difference between Tokamak and Stellator reactors It resides in its geometry. The former have a toroid form (or donut), and the latter have a more complex geometry that resembles them to a twisted donut on itself. However, the fundamental difference between these two designs is that the reactors Tokamak They require that the magnetic fields that confine the plasma are generated by coils and induced by plasma itself, while in the reactors Stellarator Everything is done with coils. There is no current within the plasma. This means, in short, that the latter are more complex and difficult to build. Fortunately, Wendelstein 7-X experiment is already delivering extraordinarily promising results. Global record in long -term plasma The first tests carried out in this fusion reactor between 2015 and 2018 came out as planned, so in November of this last year there came an important moment in its itinerary: it was necessary to modify it to install a water cooling system that was able to evacuate more effectively the residual thermal energy of the walls of the vacuum chamber, as well as a system that allowed the plasma to reach a higher temperature. The works required by these modifications concluded successfully in August 2022. The electronic cyclotonic resonance heating system delivers more than 1 MW of power to plasma When scientists introduce such important modifications in such a complex experiment they are forced to review everything obsessively before launching the machine again to make sure that everything will go correctly. Fortunately everything went well and in February 2023 the Wendelstein 7-X reactor reached an important milestone: He managed to confine and stabilize plasma for 8 uninterrupted minutes in which the reactor delivered a total energy of 1.3 gigajulios. But it wasn’t enough. Now it was time to submit this machine to a new maintenance and renewal phase with the purpose of going further. A year later the reactor was prepared again to carry out new experiments, and now has significant improvements. The technicians who have worked on it in recent months have optimized the control and data acquisition systems, have improved the plasma heating system and have implemented about 50 additional diagnostic tests. Of all these improvements the most relevant is the heating system because it is now capable of generating more than 1 megavatio of power in the plasma thanks to the microwave application. This technology is known as the electronic cyclotonic resonance heating system (ECRH or Electron Cyclotron Resonance Heating in English). The first results have not taken to arrive. And it is that on May 22 this German reactor registered a world record by sustaining the fusion reaction through a high performance plasma For 43 seconds. To date, no other merger machine has prolonged both the triple product in long -term plasma discharges. Understanding what the triple product is is not difficult (it is also known as Lawson’s criteria). In fact, it is nothing more than a metric that evaluates the density of the plasma particles, its temperature and the time that magnetic confinement lasts with the purpose of measuring the performance of the fusion reaction. This strategy is essential because it allows engineers to determine if the fusion reactor has overcome the threshold that allows it to generate more energy than it has been necessary to use to heat the plasma. Once this point has been reached, the energy balance becomes positive and the fusion reaction can be sustained over time without investing energy in the heating system continuously. This milestone would not have been possible without the intervention of the new frozen hydrogen packages developed by the Oak Ridge (USA) National Laboratory. However, there is something else that is worth not overlooked: during the campaign that the reactor has just finished, he has delivered 1.8 gigajacles of energy, so he has clearly exceeded the 1.3 gigajulios that he reached in February 2023.

Just when the batteries were breaking all the records came the ultra-infinity mobiles. China has a lesson for them

by

He Samsung Galaxy S25 Edge He has just come to the market. It is a telephone that presumes finishes and whose main argument is in an ultra -launch design that differentiates it from your family brothers Galaxy S25. The problem? Miracles do not exist, and having less space for components translates into a smaller battery. The only solution to get less size to have a decent battery density is to bet on the Silicon-carbona technology that Samsung has not implemented in its EDGE. Result? A high range with 6.7 inches and 3,900mah, A countercurrent movement of the industry. One day of use. Despite the little battery capacity, Samsung promises that its Galaxy S25 Edge will last a day without too many problems. The problem here is that, for a while to this part, the rest of the manufacturers have been obsessed that their phones last more than a day. In fact, today a day of intensive use is a somewhat poor figure. Devices like him Samsung Galaxy S25 Ultra, iPhone 16 Pro Maxand virtually any high range from China reaches two days of use or, at least, the day and a half with intensive use. There are no miracles in optimization. The phones They are increasingly powerfulits processors are comfortable between the three and the four nanometers and we have been with optimizations in each of the telephone components to minimize energy consumption. But the new bright screens consume energy, the Snapdragon 8 Elite It is something swallow, and have a phone with the ability to record 8K, execute games in maximum resolution at 120 Hz and, ultimately, to pull with everything, spend drums. A countercurrent. 10,000mahit is what has managed to introduce real to a phone with a habitual thickness. Honor already has phones with batteries of 8,000mahand this year it has been clear that even the old 5,000mah barrier begins to fall short. Speaking an Android phone with 3,900Mah is risky, a lot. We are facing a change of generation in batteries. That day and a half is about to become a new scarce figure, and that is that with the democratization of batteries close to 10,000mAh we will have better autonomies than ever. Silicon-carbon is still a face and incipient technology, but China is squeezing to turn it into the standard of its phones. The solution. Xiaomi herself told us that some of its mobiles land with less battery in Europe with respect to China for a simple reason: The costs. These gigantic batteries are not economical, and manufacturers like Samsung bet on traditional technology to contain the price of their devices. Despite this, the only alternative to view if the ultradelgated phones want to succeed is to bet on silicon-carbon, even if necessary to cut in other specifications. Can. The ultra-of the mobile with good battery exists, and we have examples in the Tecno Spark Slim. 5.75mm for a 5.200MAH battery phone. It is an exception, yes, but it is the proof that it is possible to launch phones with large batteries and record thicknesses. They are not alone. The next stone on the road to the ultra-decaded mobiles will put Apple with its iPhone 17 Air. A phone that, except miracle, will also land with a traditional battery of a fairly content size.

March is already the rainiest month since we have records in several areas of Spain. And only 10 days have passed

by

The other day I spoke with known that I told me that, when I was little, in the Ayamonte of the 60s and 70s, they went to school with water boots. Not only that, he told me, “I remember the white houses putting green because it kept raining.” At that time, I was not sure if it was true or it was nostalgia altering the memories of childhood, but seeing what is happening at the southern end of the peninsula, I would not surprise me anything. And it is that March 2025, just It has just converted in the most rainy month in several places in the country. Among them, the Aaemet Huelva Observatory – Ronda whose maximum historical data, since 1985, had been 164.6 mm. Yesterday, at 20:30, I had already collected 169.2mm. And there are 20 days left. Huelva, however, is simply a metaphor of Spain. An poisoned gift. Although the type of rain that is reaching us from the Atlantic is fantastic and does not have the torrentiality levels of the Danas, there are a point also begin to give problems. First because we have no infrastructure that can collect, accumulate and distribute all that liquid. As we commented a few days agothe red basin, the Odiel and the stones was above 94% of its capacity. That placed it at the level of the interior basins of the Basque Country and above Galicia or the Eastern Cantabrian. It is true that these data have trap (not only have little storage capacity, but in the area many coexit dead reservoirs Cargaditos of mining waste), but is indicative of what is happening in the rest of the country. Floods throughout the country. The clearest case has happened in the Toledo municipality of Escalona and its region. There, the Alberche River (just the one who, As we said yesterdayhe was going to receive an unprecedented amount of water) has overflowed and has caught many people with the step changed. However, more than 15 tajo stations They were yesterday Above the red warning threshold. And, if we expand the frame, we will see Floods in Sevillein The Golden Costain Vitoria or in Cartagena. Catalonia, for the first time in years, seems to drought endemic that lives. Are they good news? Yes, but with nuances. Obviously, water will come very well to face the next summer months. It gives us an irreplaceable margin to decide whether we want to learn from our previous mistakes. As explained in Datadista“From the deep drought of the 1990s, each dry period has served to implement emergency measures (…) or allow practices that were not eliminated when the rains returned, they were used to expand irrigation, increasing the problem of overexploitation and contamination of aquifers and wetlands to which they feed.” What are the nuances? The first is that ‘too much blow water’ also creates problems. Citrus flowers or Strawberry crops can begin to rot (or infect with fungi) in full campaign. That is, climate changes catch crops in different phases of the usual ones and that has impacts on the productive system. But the second nuance is perhaps more important: that the incentives not to take advantage of this blow of luck and not Implement the changes that The Spanish Water System needs. And, in the meantime, it does not stop raining. Nor does it seem to stop doing it.

This Chinese fantasy film is destroying records in his country and has already advanced Marvel in more than one milestone

by

‘Ne zha 2’ is sweeping. Maybe you have not been able to talk about this animated Chinese production (the first installment was titled ‘Nezha: the rebirth of a god’ and You can see it in Netflix), but it reached Chinese cinemas taking advantage of The celebration of the Chinese New Year, the most profitable and coveted day for the premieresand in 5 days he kneaded 435 million dollars. To get an idea of ​​how much that can be, ‘Avengers: Endgame’ added something less, 427 million, in its first five days in US cinemas. If you continue on this path (And you are following: In its first week, it has reached 671 million), it has another even more spectacular milestone to exceed: become the first feature film that exceeds 1,000 million dollars of collection in a single country. Again, Disney shadows him with ‘Star Wars: the awakening of force’, which raised 936 million in the United States. It is the one that shows the greatest brand so far. Finally, ‘Ne zha 2’ has another record to overcome, and everything indicates that he will: be the first Chinese film to exceed one billion collection. ‘The battle of Lake Changjin‘He stayed at the doors, with 913 million at the box office. Finally, last milestone: ‘Ne zha 2 is about to advance to the first’ Nezha ‘, which became the first animated film that exceeded 700 million collection in a single territory. Many brands and many milestones, as can be seen, for a film that continues the argument of the first part and that remains starring Nezha, a protective deity that appears in the Buddhist, confucian and Taoist folklore. The argument of these animated films are based on a classic Chinese novel of the 16th century, which in turn has inspired other films in the country such as ‘New Gods: Nezha Reborn’. In Xataka | ‘Vaiana’ is already the greatest success in streaming history, and there is a clear responsible: the way of watching children’s films
