Elon Musk turned an abandoned US factory into the most powerful supercomputer in the world. Nobody thought of the neighbors

by

It would be said that Elon Musk has created A perfect circle Around what until recently it was an abandoned factory on the outskirts of Memphis. There has installed Colossusthe most monstrous supercomputer on the planet to boost AI to new limits and that it defines the future of cars (of Tesla). In order for the combo, it is complete to the richest type in the world, everything is in turn fed by the megabaterías of Tesla. A Win Win For Musk’s framework, although with a problem: the neighbors. A colossus … toxic. The story brought it This week the CNN. In the summer of 2024 Musk transformed an old abandoned factory in southwest Memphis into what he himself proclaimed as “the most powerful supercomputer on the planet.” The project, promoted by its artificial intelligence company XAIpromised to turn the city into a New Technological Mecca (The so -called “Delta Digital”) with Quality jobs and dozens of millions in taxes. However, for Botxtown residents, a mostly black and impoverished community that has lived with decades with Industrial pollutionXai’s arrival has meant a déjà vu environmental: A new source of pollution settled without clear permits, with an apparent contempt for public health. A computer that consumes. To feed “Colossus”, XAI installed 35 gas turbines capable of generating Up to 420 megawattsreleasing toxic gases Nitrogen oxidesultrafine and formaldehyde particles. The problem? Who did Without licenses of air required, welcomed to a legal exemption for temporary machinery, which according to experts does not correspond to it. The area already houses 17 polluting facilities, and various studies indicate that the risk of cancer in the area quadrupple acceptable levels For the EPA. Memphis also has the higher rates of children’s hospitalizations by asthma in all Tennessee. Realities. While the mayor of Memphis, Paul Young, celebrated the transformative potential of the project and anticipated more technological investment, local leaders such as state representative Justin Pearson They have denounced have been excluded from the process. The lack of transparency adds to an obvious regulatory collapse: an installation with the power of an electric plant operating without permits in the middle of a residential neighborhood. To this we must add the most recent thermal snapshots (image below) that indicate that at least 33 of the turbines They were operational in April. Following the controversy, XAI finally requested permission for 15 of them and withdrew 12, but, as CNN counteddamage to trust is made. Promises Project defenders say that “leading standards in emissions” will be achieved, but residents see the employer repeat: Employment promises well paid that do not specify (because the reality is that the data centers use very few), while the environmental load falls on those who have less resources to defend themselves. Plus: The story of Botxtown It is not new. Already in 2021, its inhabitants achieved stop a pipeline that would cross their lands, and in 2023 they closed A sterilization plant that emitted ethylene oxide. For them, therefore, XAI is simply the last chapter of a long struggle for the right … to breathe. Innovation or regression. It is the last of the legs to be treated with the controversy. XAI installation reflects a broader national dilemma than We have counted before on the rise of artificial intelligence and its real cost. Amid the enthusiasm for turning the United States into the “Global Capital of AI” (according to New EPA Guidelines Under the government of Donald Trump), the expansion of data centers Devoradors of energy advances without a serious evaluation of its environmental implicationsespecially in vulnerable communities. The unconditional support of the Executive to Musk, one of Trump’s closest advisors, coincided with the Weakening of environmental policiesthe elimination of ecological justice programs and a rhetoric that prioritizes economic efficiency over human health. The first “stone.” The contradiction seems clear: IA is promoted as the future, but it is fed with fossil technologies of the past, generating private benefits while the risks and damage are socialized. “If innovation chains you to fossil fuels, that’s not progress,” Keshaun Pearson remembereddirector of Memphis Community Against Pollution. Thus, residents fear that what happens in Memphis is just a general essay of what could soon be replicated in similar neighborhoods throughout the country. A tireless struggle. He counted An NBC report That in Botxtown, indignation coexists with fatigue. Many, such as Sarah Gladney (respiratory and resident patient to a few km from the installation), feel they live in a perpetual battle. The possibility of a second meginstalization of XAI, already projected in the city, only increases the sensation of siege. “It seems that we are always at war,” He underlined. A paradox, since while local officials speak of economic transformation, neighbors simply speak of survival. In the background, the collision between the promises of peak technology and the old reality of systemic pollution raises an uncomfortable question: Who pays the price of this digital revolution? In the southwest Memphis, the answer seems sadly clear.

We thought we had found a safe and sustainable alternative to oil derived. We have to keep looking

by

Many years ago, long before “Do you want a bag?” and The new European plugsI got a small summer job distributing potato starch bags by Media Granada. The world had begun to account for the huge problem of plastic bags and prepared to The day later. In that sense, the potato starch was an extraordinary thing. First, because it was ridiculous, extravagant and left everyone out of play (a bag of what?); But above all because starch -based bioplastic seemed like a much more sustainable and renewable material. The issue is that we begin to discover that they have problems. What is a starch -based bioplastic …? Because, although potato bags will always be in our hearts, the true revolution of this family of products occurred when They reached the world of the container for food, disposable utensils, films to cover or even single -use medical products. … And why are they a problem? A newly published study in it Journal of Agricultural and Food Chemistry He has just shown how “animals that consume particles of this alternative material develop health problems such as liver damage and imbalances in intestinal microbioma.” That is, by Use the exact words of the authors of this study“Biodegradable plastics based on starch may not be as safe or beneficial for health as originally supposed.” Eat plastic. The researchers They compared three groups of five mice: a group (control) consumed normal feed; The other two groups that consumed foods with particles derived from the ‘biodegradation’ of starch -based microplastics. There are two because each one had a dose (low and high) calculated and climbing from the planned daily consumption for a normal human being. They monitored them, studied them and there the problems began. What did they find? In the mice that consumed high doses of bioplastics They presented Damaged organs (including liver and ovaries), problems when handling glucose and even deregulated genetic pathways. “Prolonged exposure to low dose of starch -based microplastics can cause a broad spectrum of health impacts, in particular the alteration of circadian rhythms and the alteration of glucose metabolism and lipids,” explained in the American Society of Chemistry Yongfeng Dengmain author of the study. Should we worry? Well yes and no. Obviously, the results of the investigation are peliagudos, but not alarming in excess. Actually, if confirmed, the results are very similar to those of conventional plastics. In addition, the study is small and the investigation is in a very initial phase. To put it in a summary way: we still do not know how much there are in these results. There is much to work, investigate and regulate. And, deep down, the most interesting thing about this work is not its provisional results. It is the need not to give anything for granted and take care of the movements that we are doing in the development of new materials. It is, in short, a reminder that everything remains to be done.

We thought that the olive oil sector was so broken that the olivers were losing 270 million euros. Is more than double

by

When Jesús Cózar, general secretary of UPA Andalucía, gave a press conference saying That “the olive growers have stopped receiving 270 million euros in the month of March, or what is the same, more than 8 million daily, due to the current situation of ruin prices in origin,” many raised an eyebrow. That’s the milkmaid accounts, they said. Now a team from the University of Jaén, the University of Córdoba and the Institute for Agricultural and Fisheries Research and Training has calculated the alleged imbalance of the oil market and a clear conclusion has arrived: Cózar fell short. Market imbalance? In general terms, we can conceptualize the olive oil market as if it were a huge equilibrium machine: the final price of the oil arises from a balance in which many things intervene; But above all, the total stocks and the expected demand. If there is little oil, as happened in recent years, the price tends to rise until the demand fits the amount there is. If there is a lot of oil, it occurs just the other way around. Well, with that principle in mind, we can evaluate whether the market is unbalanced: that is, if the price is above or below what it should be. That is what they have measured. After weeks and weeks with the fly behind the ear, the Provincial Council of Olive Oil of the Provincial Council of Jaén requested a report on the current market situation. To evaluate the real situation, the UJA/UCO/IFAPA team has used a series of new computer analysis models of imbalances. According to your conclusionsthe price of the AVE in origin should be between 5.55 and 6.14 euros/kg. The fork is due to the fact that some data are still missing and the final production can reach between 1.29 and 1.5 million tons. What does this translate? Basically, the 270 million euros spoken by the Secretary of the Andalusian UPA are an anecdote: what the Spanish olive groves are ceasing to receive are 626 million euros. From October to March, the average price at source in these months has been € 4.49. That is, one euro below the minimum estimated price in the study. What is happening? They don’t even know. A few days ago, Juan Luís Ávila, the head of the Olivar de Coag sector He wondered “What is happening in the market so that prices remain artificially low.” In fact, he is preparing a complaint with the National Markets Commission and the competence to find out. Why is it interesting? Because All this situation (That arrives, remember, at a particularly delicate moment for the olive industry after years of crisis and hoping that this year would be resolved) is very complicated: it is still clear that, Despite the weight of Spain in the sectormarket mechanisms are easily alterable. And not even in contexts Where we have the “pan for the mango”there are useful instruments to have it controlled (or even know that everything is working correctly).

The players of ‘Gran Tourism’ thought that the RUF were the Porsche de Hacendado. They were the opposite

by

The fancy It is an essential element in video games. It can be the theme, such as medieval fantasy of a ‘Dark Souls‘, but it can also be the relative to the fantasy of power in a game like’God of War‘ either ‘Civilization VII‘. The cars games They satisfy our fantasies to pilot the car of our dreams, unless your dream was to pilot a Porsche at 250 km/h in the most famous simulator of its time. Because there what breaks fantasy is something as earthly as … money. Luckily for years a brand went to the rescue of lovers of German sportsmen: Ruf. The problem. You are a young car enthusiast, buy the driving simulator on duty and discover that you can drive a Lambo, a Ferrari and brands of brands you didn’t even know, but not the one you really want: a Porsche. With the naivety of childhood, you did not imagine that a more ‘cheap’ brand that others were not in your video game, but at least you could be content with RUF. RUF cars looked like a tuning Porsche and it wasn’t what you wanted, either had their shield, but it served you. You thought it was like the ‘Pro Evolution Soccer‘When they modified the names of the players whose license belonged to the’ FIFA ‘saga, but you kept wanting to drive a Porsche and did not understand that the’ Need for Speed ​​’had the brand and’ Gran Tourism ‘no. Blessed (and damn) licenses. Because in video games, licenses are a blessing, but also a problem. Let’s go back to football sagas. While in FIFA we had Cafu, Rivaldo Oa Ronaldinho, in PES we had Facu, Ravoldi Ya Naldorinho. His gestures and faces simulated real players, but their names were, as little, original. The reason? The Japanese football saga did not have the licenses of real players, competitions or teams. And it happens with everything, really. We recently told you how there are extremely similar weapons to the real in shooting games, but many times the names are invented because The corresponding license has not been paid. And if we get into the subject of Royal Group SongsIt is a curious eggplant. There are games that have been edited through a patch to eliminate songs whose license has expired (‘GTA IV‘, for example) and others that have completely disappeared (‘Spec Ops The Line‘). Electronic Arts. It is as simple as, if you want to show a real person, a song, a weapon or whatever in a video game, those responsible for it must pay the brand. And this is something very juicy for companies, since they can promote their video game, precisely, with that license they have paid. In the case of cars, all brands included in a video game receive money for your rightsbut with Porsche he went one step further. At the beginning of the century, Electronic Arts was very strong in the field of driving with its saga ‘Need for Speed’. Before launching at night street races and cars modifications, in 2000 ‘Need for Speed: Porsche Unleashed 2000’, a video game in which it should not be explained what Marca was the protagonist. The problem (for the rest of the companies)? That EA and Porsche signed an exclusivity agreement that lasted 15 years. Porsche 911 Carrera to the left, Ruf ‘YellowBird’ on the right RUF. Since then, the EA saga had Porsche cars that we could even modify, but in simulators like ‘Gran Turismo 2‘The mythical firm was not. In others like ‘PROJECT GOTHAM RACING‘ either ‘Forza Motorsport‘We also had Porsche, but this was the result of an agreement between Microsoft, Electronic Arts and Porsche herself. Now, why do you remember that you could conduct a Porsche 911 career in the ‘Grantu’? Very easy, because the Porsche 911 Carrera was in the ‘Grantu’. Well, more or less. The one that was Ruf, and a mythical model of ‘Gran Turismo 2’ was the RUF CRT YellowBird of 1987. Aesthetically, it was a Porsche 911 Carrera 3.2 and, precisely, what Ruf does in reality, outside Gran Turismo, is to modify Porsche cars in such a deep way that it is considered a totally independent brand. Porsche was created in 1931 and RUF In 1936 and what they do is build their cars on a bare chassis of Porsche, but using their own engines, suspensions, gearbox or body elements. In short: it is not a Porsche with steroids, it is something else At the legal level. The work is so deep that they are legally considered Ruf cars, not Porsche, and that is the reason why some games without Porsche’s license could have cars like the Porsche of our dreams, but without the shield or name of Porsche. What would happen to me and you will think that that YellowBird was the 911 race of ‘Gran Turismo 2’ with a different name and slightly different body because they could not have the Porsche brand, but as I explain, we were wrong: it was not a false car, but totally real. Happy end. That is why the RUF brand was in games like the ‘Gran Turismo’ or ‘Driveclub‘Instead of a Porsche that appeared in other sagas, next to RUF in case of’Forza Horizon 4‘. However, in 2016 the license agreement between the German firm and Electronic Arts expired, which allowed other racing games to incorporate the mythical German house. And a sample of the desire that ‘Gran Tourism’ had to have Porsche in its catalog is that the brand itself detailed The dozens of models in the latest installment of the saga … and that on the cover of ‘Gran Turismo 7‘Porsche VGT appears next to Mazda Rx Vision GT3. Now, we can pilot a 911 in almost any game, but those of us who grew up with RUF and ‘Gran Tourism’, we will never forget the mythical YellowBird.

There was a time when we thought the birds migrated to the moon. Until an arrow released in Africa fell in Germany

by

Spring is a time that I always liked. Not for the Horrible processionarybut for the return of the swallows And, above all, of the storks. After a long winter, They return home to nest. Imagine the surprise if, one day, one of those stork appears in your locality with the neck crossed by an 8 -centimeter arrow. Stop imagining because that happened in 1822 in a German city. And far from being an anecdote, it became a key event to unravel the mystery of why birds They disappeared in winter. The doubt. Now it is no mystery and it is something that we learn at school since childhood, but not so many centuries, people did not know why, good at first, the birds were in autumn and reappeared in spring. Those Migratory processes in which even the smallest of the birds rEcorren thousands of kilometers without stopping They were not understood, which forced the thinkers of the time to launch hypotheses and theories that, in the absence of evidence, since they were accepted without further ado. One of the answers was evident. And it could be none than … Alien birds. That is what thought Charles Morton, a Harvard academic who, in the seventeenth century, suggested that the reason why some birds disappeared in winter was because they migrated … to the moon. Most likely you have raised your eyebrow thinking something like “impossible, they could not be so illusory”, but you have to put into the skin of someone who had no way to check the phenomenon and it was still an answer to a real mystery. Because what they knew was that they disappeared for months, but not the place they were going to. And as they saw the moon from Massachusetts, but not Colombia, because the answer was clear. But don’t believe it was the only crazy theory of the time. Aristotle, already in the IV AC theorized about the possibility of being transformed into other species or even shuffled over his hibernation underwater. Morton rejected this idea because it was too fantasy (not like his, of course). The arrow. Morton even calculated that the trip to the moon had a month away and another back, sleeping much of the time and surviving thanks to his body fat. The truth is that, in the absence of better theories, it was not bad (despite my jocular tone, we talked about the seventeenth century and the media they had). However, little by little the idea that these European birds were going to other places during the winter. And the definitive test was brought by a stork. A good day of 1882, north of Germany, someone shot a stork, who fell down and with a capital surprise for those present: he had an 8 -centimeter arrow through his neck. The question was no longer how I could fly with such a breakdown, but where the arrow had come from. Brava PFEILSTORCH. Thus, they took the body of the stork to the University of Rostock, where the researchers examined the projectile and concluded that it was an arrow belonging to some group in the center of Africa. As it was impossible, or tremendously unlikely, that someone launched something like that on European soil, the response became evident: that stork had traveled more than 3,000 kilometers from the point in Africa in which winter had passed and where it was killed in Germany. Baptized as PFEILSTORCHIt was dissected and preserved in perfect condition in the Zoological Collection of the University of Rostock thanks to its undeniable importance in the world of science and ornithology: it was confirmation to the suspicions that, indeed, migratory birds or became anything else, nor slept four months underwater or went to the moon: they traveled to the warmest places during the European winter. Clue. After Pfeilstorch (which means “Flechy stork” or “storks crossed by an arrow”), they found more specimens In Europe with the same characteristics: arrows stuck somewhere in your body. This is not so uncommon in large birds, which show great resilience to wounds that do not compromise flight or its basic functions. Once they are injured, if not seriously, the wound stabilizes and the bird can continue with its life. With the inclusion Of the rings on the legs of the birds by the Danish HC Mortensen in 1899, the researchers systematized the study of specimens to verify that those who flew from Europe before winter, disappeared and then returned, were the same. Thus, we can say that this arrow launched in Africa that landed in Germany was the first bird monitoring system, a coincidence that allowed obtaining the first conclusive data on the migratory practices of the birds.

We thought that oil was a thing of the past. But the oil companies that have remained faithful to raw live their golden age

by

While the rise of renewables continues full -potato wind, as can be seen in projects such as GLOBAL RENEWABLE Watchthe big refineries are starring an unexpected return to the center of the energy stage. The commitment to hydrocarbons. Unlike other companies in the sector, French TotalEnergies did not turn completely in an energy conversion. Yes, he invested in renewables. Yes, he developed liquefied natural gas projects. But he never abandoned his base: oil and gas. According to Reutersthe company has increased its UPSTREAM production (crude and gas extraction) compared to the first quarter of 2024. Although oil prices are below the level of a year ago, gas sales have improved, and fuel production is returns to be profitable. Refinement in recovery. The situation is dragging the effects of a profitability drop that has affected the entire industry. According to the company, the profit margins in the oil refining in Europe have increased in the last six months, but there are still 59% below the levels of a year ago. All this is due to multiple reasons, such as a weak demand, the growth of New refineries in Asia and Africa, OPEC+ overproduction and Trump’s tariff war. Even so, as the news agency has detailed, Totalenergies has increased fuel production, partially benefiting from that slight recovery on the margins. The strategy. According to Ahmed Ben Salem, an analyst at Oddo BHF, among the greats of the sector, Totalenergies is “the most resilient in a weaker macro environment, backed by diversification towards liquefied natural gas and renewable energy.” And it is not the only one that has found a new balance between transition and profitability. While Timenergies clings to a hybrid strategy, its Anglo -Saxon rivals are also adjusting the course. BP, for example, has trimmed His green ambitions to focus again on hydrocarbons. Exxonmobil He has opted strong for carbon capture. Together, all of them seem to be converging in the same idea: crude has not yet said his last word. The paradox of the transition. In the decisive decade for climate action, refining recovery sounds almost to Anatema. Can the energy sector continue to win time with fossil fuels without losing the decarbonization train? This dynamic does not occur in a vacuum. As I know He explained The tariff war and the firmness of the OPEC+ to continue producing the barrels has caused a drop in oil prices, with the Brent and the WTI stabilized around 60 dollars a barrel. This scenario impacts directly on the refineries, which try to balance fossil profitability with the growing stark pressure.

We thought we had solved the mystery of the giant “trees” of the Paleozoic. We couldn’t be more wrong

by

More than a century ago, when the first known fossils of Prototaxitesintuition said that it should be the remains of a tree. Decades of study revealed to paleontologists that this fossil did not belong to a plant, so everything seemed to indicate that it was an immense fungus. Now a new study has reopened this unknown. Neither plant nor fungus. The study in question has revived the discussion About the nature and taxonomy of Prototaxitesprehistoric beings that so far the catalog scientific consensus as fungi. The involvement of “taking out” these beings from the evolutionary branch of fungi is that perhaps these beings belonged to an extinct and unknown branch of the tree of evolution. 400 million years ago. What we do know about Prototaxites For the fossil registry, it is that being trafficking with organisms that were alive towards the middle of the Paleozoic era, does Between 420 million and 375 million years. These beings had a more or less cylindrical structure, similar to a trunk and stood up to eight meters above the sky with a diameter that the subway could reach. These measures and their age make them one of the first large beings of those of which we have record in the fossil registry. The debate on the nature of these prehistoric living beings seemed to mid -2000s. It was then that an analysis revealed that the Prototaxites They did not obtain their carbon from photosynthesis, as is the case of plants, but obtained from other living organisms, as fungi do. Rhynie Chert. The new study that reopens the case It now contributes tests that this being did not belong to the kingdom of fungi and focuses on one of the known species of this genus, Taiti prototaxites. The team resorted to the fossils found at the Rhynie Chert site in Scotland. This site contains not only fossil remains of this species, but also of fungal species and others belonging to other kingdoms of nature. Similarities and differences. The new analysis of the fossils of this species ran into some similarities with fungal structures such as those that could be expected. However, despite having tubular internal structures similar to those of fungi, these tubes in P. Taiti They branched and linked in a different way from what they could expect. That was not, however the strangest detail. The analysis did not detect in fossils evidence of the products that are associated with the presence of chitina, a compound present in the cell walls of all contemporary fungi and that we know was also present in prehistoric fungi. They found that the chemical “firm” was more similar to that left behind by lignin, a polymer that we associate with vascular plants. The study has been published for now draft In the repository Biorxivso the standardized scrutiny of peer review has not yet passed. So what? This detail implies that we must extreme caution when drawing conclusions from the study we have in front. Even so, the signing team of the study outlines in this its conclusions, in principle preliminary. In his study, the team concludes that “the morphology and the molecular footprint of P. Taiti It is clearly different from that of fungi and other organisms preserved with it in Rhynie Chert, and we suggest that it is better considered a member of a group not described and totally extinct of eukaryotes. ” In Xataka | An amateur fossil search engine is behind a curious finding: vomiting of the dinosaurs era Image | Іщн

We thought they were the red color in a galaxy he indicated that he was dead. There are those who believe we are wrong

by

A simple and useful way of knowing if a galaxy is old or if on the contrary it is full of new star formations is in its color. The rule is simple: the most reddish galaxies are usually older; The most bluish, young. Young and red. Now a researcher at the University of Missouri has raised a third waythe possible existence of reddish but still alive colored galaxies, that is, in the process of forming new stars. Among other implications, this could mean that our universe forms even more stars than we thought. Red or blue. Galaxies are usually categorized according to the color of their stars. Blue stars usually shine with more force for less time, so when the blue tones predominate we know that new stars are still forming. The stars with warmer tones resist more so when a galaxy dies, that is, when it stops creating new stars, these more reddish stars are what remains. However, there is something that escapes us in this hypothesis. According to Charles Steinhardt, author of the new study, this model raises certain inconsistencies, for example in the ratios between stellar masses and masses of black holes, and enters the initial mass functions of red and blue galaxies. What if they are not dead? In An article Posted in the magazine The Astrophysical JournalSteinhardt raises the existence of a different category, red and young galaxies. The key would be in the fact that in these galaxies, the stars formed would be of less dough and that therefore, also the youngest would shine with reddish tones. “The red -star formants mainly produce little dough stars, which would make them look red despite the permanent births of stars,” Explain in a press release Steinhardt. Birth and fusion. One of the keys to this hypothesis is in the post-stallid galaxies (Post-Starburst). The galaxies can go from being young stars producing to lifeless galaxies in two ways. The first, through a slow and natural evolution; the second, after a burst of stars (Starburst). When two galaxies collide, the subject of both meets, accelerating the accumulation process that gives rise to new stars. This makes the galaxy go through a stage of rapid stars formation, a stage that leaves the galaxy without fuel. In his hypothesis, Steinhardt raises the possibility, that some of these galaxies have been forming red and small stars from the beginning, and not being the result of a burst. This possibility would imply, Explainhave to reclassify some of the galaxies we know. More stars. The new hypothesis postulates that red galaxies continue to create new stars which in turn implies that our universe produces even more stars than those we believed. “The existence of these galaxies can mean that the universe has formed a significantly greater number of stars than before,” Steinhardt defends. The galaxies are complex formations and we may still notice important details about them. Details such as the details of their life cycles, adds the researcher.

Six gadgets that I never thought I would need and have improved my daily life in 1000%

by

During these last years I have bought a good amount of Gadgets or accessories. I am not going to lie to you, some have not liked anything and I expected much more of them. But there are others who I liked much more than I thought, and I have come to give them even daily utility. Therefore, I have gathered the six accessories that I liked the most than I bought in recent years. Logitech MX Vertical by 69.94 eurosa mouse with ergonomic design that offers a very pleasant comfort in hand. Logitech G Pro x Tkl Lightspeed by 181.22 eurosa spectacular mechanical keyboard with macros configuration and quite silent and pleasant keys. Huawei Watch Fit 3 by 113 eurosone of the best activity bracelets I have had so far. Tomoc backpack by 69.99 eurosa travel backpack with a lot of ability to avoid always traveling with a suitcase. TP-LINK TAPO P100 by 10.90 eurosan intelligent plug that I am taking a lot. Soundcore Space Q45 by 94.99 eurossome bluetooth headphones that I love. I use them to work and for personal use. Logitech MX Vertical When I started having more and more discomfort in the elbow and the arm when using the mouse, I decided to prove how the work worked Ergonomic mice “Conconcreously the vertical ones,” of which so many good opinions had read and heard. I tried luck with the Logitech MX Vertical And I can’t be more delighted. Although the inconvenience has disappeared completely, I still use it practically daily, alternating it with the Logitech G502 Hero. Right now it is found by 69.94 euros. I paid something more for him and it is worth every penny. What I like most is that it is very comfortable in hand, I do not miss anything other mice (as a greater number of buttons), The battery lasts a barbarity And I use it on several computers simultaneously, since it has multidispositive connection. The only “paste” I could put is that it is not compatible with the Logitech G hub software, but with logi options+. * Some price may have changed from the last review Logitech G Pro x Tkl Lightspeed I never thought I would spend more than 50 euros on a keyboard, but I made the leap to mechanical keyboards with the Logitech G Pro x Tkl Lightspeed. Is very expensive (181.22 euros), But I am very delighted with him. I was looking for a mechanical keyboard that did not make too much noise By pressing the keys, and I chose quite well – not before seeing several dozen videos about certain models. The most useful of this keyboard is that It has macros —The “F” keys become macros when pressing the “FN” key – and I have it both for certain shortcuts and for text writing (text can be added so that by pressing the key it is written automatically). The battery also lasts a barbarityyou can customize the lighting key per key and includes a multimedia wheel at the top. As added, I have placed a resting so that writing on the keyboard is more comfortable. Specifically I bought Razer for TKL keyboards, although it is already discontinued. This, also of Razer, is practically the same and costs 33.46 euros. Logitech G Pro x Tkl Lightspeed * Some price may have changed from the last review Huawei Watch Fit 3 Throughout these years I have had several activity bracelets, and although at the time I liked it enough I was fed up that the straps were broken within a few months. Therefore, I decided to buy the Huawei Watch Fit 3 In its version Velcro strap And it is a pass. It is, from afar, the best activity bracelet that I have had so far and can be found by 113 euros in Amazon and for 109 euros in the official huawei store; The latter also includes a gift strap. The rotating crown is a success; It is super useful and vibration feels very good. It includes several sensors to monitor physical activity, but what I like most is that it includes many sports modes and some training. It even comes with Heating and stretching routines. It can be found slightly cheaper in other strap configurations, but I already tell you that it is Velcro’s a thousand laps that I have had so far. * Some price may have changed from the last review Tomoc backpack I usually travel a lot, so a year ago I was looking for backpacks of great capacity not to always take my suitcase. After shuffling many options, I finally opted for the 40 -liter Tomoc. Its price is 69.99 euros (I paid much more) and fits everything. It does not come with as many pockets as other alternatives, but it does not need. In the inside we have two large compartments: one that I use for clothes and another that I use for the laptop, the tablet and the loaders. It also has other smaller pockets for documentation and little else. The most interesting is the construction: It feels like a very rigid and resistant backpack and the rear is paddedso it is a very comfortable backpack to carry, even if we carry a lot of weight. In addition to the backpack, I also bought the compact bandolera Tomoc Compact X-Pac that I always use on my trips (and for when I leave home). There I always carry my Ereader Kobo Clara 2E, the Nintendo Switch, headphones, keys and much more. In this case, we can find it for 47.19 euros. Although he says it is a bandit, its compact design is closer to what is a fannyry, but with enough space to carry many things. 40 -liter Tomoc Backpack * Some price may have changed from the last review TP-LINK TAPO P100 Another accessories I use every day are my two smart plugs TP-LINK TAPO P100. Certain appliances, loaders and the work team turn it off during … Read more

AI is a great black box that prevented us from knowing how “I thought” inside. Until now

by

AI do not have No idea what he says Not why he says it. When he responds almost everything makes sense – even his legs of legs – but he only seems to us, because the machines do not understand what they do. They simply do. We do not know how the IAS think inside, but that seems to be able to change soon. Opening the black box. Those responsible for Anthropiccreator of the chatbot Claude, They affirm having made an important discovery that will begin to understand how the LLM work. These models work as large black boxes: we know what we give them starting (a prompt) and what we get as a result, but it is still a mystery what happens within that “black box” and how the models end up generating the content they generate. Why it is important to know how “think” the AI. The inscrutability of AI models generates important problems. For example, it makes it difficult to anticipate If they “hallucinate” or make mistakesand why they have committed them. Precisely knowing how they work inside would allow better to understand those incorrect responses to correct these problems and improve the behavior of these models. Safer, more reliable. Knowing why the IAS do what they do as they do would also be crucial to be able to trust us much more. These models would therefore allow many more guarantees in areas such as the privacy and protection of the data, something that can be a barrier for companies to use. And reasoning models, what. The appearance of models such as O1 or Deepseek R1 has allowed that during these “reasoning” processes the AI ​​apparently shows what you are doing at all times. That list of minitareas that is completing (“searching the web”, “analyzing the information”, etc.) are useful, but the so -called “chain of thought” does not really reflect how our requests are processing these models. How does Claude calculate how much are 36+59? The mechanism is not entirely clear, but in Anthropic they begin to decipher it. Source: Anthropic. Deciphering how AI thinks. Anthropic experts have created a tool that tries to decipher that black box. It is something like magnetic resonance scannars that study the human brain and allow to detect which brain regions play their role in certain cognitive areas. Long -term responses. Although models such as Claude are trained to predict the following word in a sentence, in some tasks it seems that Claude makes a kind of longer term planning of the task. For example, if we ask you to write a poem Claude you first find words that fit the theme of the poem and then go back to create the phrases that will generate the verses and rhymes of the poem. A language to think, many to translate. Although Claude has multi -mounted support, Anthropic experts reveal that their operation by handling several languages ​​is not “thinking” in those languages ​​directly. Instead use concepts that are common in several languages, so It seems to “reason” in the same language and then translate the exit to the desired language. The models cheat. That research also revealed that the models They can lie about what they are doing And they can even pretend that they are thinking when they really already have the answer to our request. One of Claude’s developers, Josh Batson, explained how “although (the model) claims to have made a calculation, our interpretability techniques do not reveal any indication that it has occurred.” How Anthropic’s deciphering works. The Anthropic method makes use of the call Cross-Layer Transcoder (CLT) that works analyzing interpretable sets instead of trying to analyze individual “neurons”. For example, these characteristics could be all conjugations of a specific verb. That allows researchers to identify complete “circuits” of neurons that tend to join in these processes. A good start. In the past OpenAi already tried to discover How their AI models thoughtbut it was not very successful. Anthropic’s work has notable limitations, and for example he does not know why the LLM pay more attention to certain parts of the Prompt than others. Even so, according to Batson “in a year or two we will know more about how these models think about what people think.” In Xataka | Universal Music has just stumbled against Anthropic by Copyright: a victory for AI technology
