Nvidia has just presented the definitive chip against Intel and AMD. There is a problem: Windows

by

The Nvidia processor for PC is the “the wolf is coming” of consumer technology. The company has been the reference for years in GPUs for gamers and flirted with SoCs thanks to the Tegra chips (which are what give life to both nintendo switch like to nintendo switch 2), but for computers they still couldn’t find a way to get equipment with 100% Nvidia guts. That just changed with the presentation of RTX Spark chips. It is a SoC that directly attacks the binomial Windows PC = Intel or AMD CPUone that is positioned as the alternative to those traditional options and that is specifically designed to compete for the heart of the consumer PC. Specifically, for laptops. Now, although Microsoft and Nvidia have been generating excitement for a few days and pointing out that it is the new era of the PC, there is a problem. Windows. The brake is no longer silicon, it could be Windows The theory is very interesting. RTX Spark combines a CPU Grace up to 20 cores that it has developed together with MediaTek (this is curious) with an RTX Blackwell GPU with 6,144 cores. TSMC (how could it not be otherwise) has given life to chip in a 3 nanometer lithography. Not only is it powerful, but it has up to 128 GB of unified memory (the same design that we see in Apple Silicon) and an interface NVLink which allows communication between RAM, CPU and GPU to be very, very fast. Nvidia talks about rendering heavy 3D scenes on laptops, running models with 120 billion parameters, and at the same time running games at 1,440p above 100 FPS with DLSS and ray tracing. The best? That Jensen Huang stood out at the Computex conference showing this in very thin and light laptops. It is the same strategy that Qualcomm follows. own Microsoft has already presented a Surface with RTX Spark and it is an architecture that makes a lot of sense in the universe of current light but powerful laptops… and also in desktop computers like a mac mini or of a mac studio. And, compared to the more traditional PC industry, the GPU is estimated to be in the range of a RTX 5070 for laptops. In the absence of testing it, it is undeniable that it looks good and that, although there are data that are not so favorable (such as bandwidth when compared to the most powerful Apple), it is a good addition to a segment in which, if we left the Intel/AMD duo, the only one that was trying was Qualcomm with devices like the Snapdragon X Elite. And there is the key: RTX Spark, like Qualcomm chips, is focused on being the heart of a Windows that is at its brightest. Because RTX Spark is a chip with ARM architecture and, although in office tasks Windows ARM It moves well, under more demanding tasks is when it begins to not be up to par. Microsoft’s system, which they themselves know is not at its best level of popularity due to the whole issue of AI features, has many shortcomings in its ARM version when it comes to gaming, precisely what Nvidia is promoting. It is also not the best optimized on laptop computers, something that is being seen with type machines. Steam Deck. The heart of the new Surface We are seeing it in recent years with PC-console asus, MSI either Lenovo: The hardware is good, but Windows drags down the experience significantly. The paradox is that the Steam Deck, being the least capable on paper, is usually more recommended precisely because it avoids Windows and relies on a system much more fine-tuned for that format. With RTX Spark, the two companies say they have been working for a long time to solve those problems and make this time, Windows on an ARM chip feel different with support for games with anticheat and native for personal agents. We will see in practice what ends up arriving, but two things are clear here. The first is that Microsoft gains aggressive hardware to compete face to face against Apple in the field of very powerful laptops with long battery life. The second is that Qualcomm is no longer alone in that corral and now it will be very interesting to see what hardware it responds with. Because Nvidia already has the chip, the CUDA ecosystem and agreements with all manufacturers, as well as the support of the giant TSMC. The “weak” link, therefore, is not silicon, it is a Windows on ARM that has improved a lot in recent yearsbut that is the element that will have the most to prove.

When asked “how much do you expect to earn” in a job interview, Bill Gates gives the definitive advice to get it right

by

It doesn’t matter how much you have prepared for a job interview or whether you have an impressive resume, because when push comes to shove, in that face-to-face job interview, it is quite common for us to have our nerves on edge. Because beyond meeting the requirements, that first impression matters a lot. Furthermore, the job interview is a minefield full of trick questions where a false step can be very costly. Given that there are questions that hide more than what they say, you move along a fine line in which you have to try to answer honestly, bet on diplomacy and at the same time extract information and leave no room for doubt to get the job but not at any price. If there is a thorny question, it is ‘How much do you expect to earn?‘. Well, a person as influential and experienced as Bill Gates has a recommendation so as not to get the answer wrong. This is how Bill Gates gets out of the quagmire of ‘How much do you expect to earn?’ If you are asked about your salary expectations, the scenario is the following: if you say a value above what the company has programmed, you may be left out of the selection process, but if your proposal is too low, it may also happen that you get a job with a salary lower than what you would like and that at the same time sounds like underestimating the value of your work and experience. But Bill Gates has been there before and is clear about what to respond. And not just now, but it was in 2020 when the tycoon and billionaire behind Microsoft offers a way out of that thorny issue. More specifically in one of the interviews from the ‘State of Inspiration’ serieswhich pitted Gates face to face with basketball star Stephen Curry. For Bill Gates, the best response to not closing doors and looking good is not to offer an exact figure and to focus on the future, diverting attention from salary to long-term value. I hope the options package is good. I can take risks and I think the company has a great future, so I prefer to get stock options even over cash compensation. I’ve heard other companies are paying too much, but treat me fairly and strengthen the options. This is the move proposed by the tycoon, since in this way you reflect, on the one hand, your confidence in the company’s future project and, on the other, how you want to contribute to its success by applying your skills, so that the chances of achieving the contract are increased. This should soon stop being a problem. However, it is worth remembering that on June 7, 2026 comes into force the European Remuneration Transparency Directive (EU 2023/970). This is a salary transparency law by which companies are obliged to report the salary before the first interview. Therefore, although Gates’ advice may be useful for companies that break the law, or when you are interviewing at a startup that is not European, in theory within Europe we will soon no longer need to go around to get an idea about the salary we are going to receive.

The world depends on gas to produce food. Paraguay believes it has the definitive solution thanks to the Itaipú dam

by

In the midst of a scenario of high tension in the Middle East and threatened trade routes, a project in the heart of South America promises to change the rules of the game for global agriculture. The British company Atome has given the final green light for the construction of Villetaa fertilizer plant in Paraguay valued at 665 million dollars, which will completely eliminate the use of fossil fuels in its production. A question of food safety. As detailed Financial Timesthe fertilizer industry’s dependence on natural gas is an Achilles’ heel for the global economy. Traditionally, most nitrogen fertilizer is produced by combining nitrogen from the air with hydrogen extracted from natural gas. However, Villeta will use renewable electricity to separate hydrogen from water (electrolysis). For Olivier Mussat, CEO of Atome, the project’s focus goes far beyond sustainability. “It’s not an ecological story, it’s actually a food security story,” declared in FT. Mussat’s warning is no small matter, since between a quarter and a third of global nitrogen fertilizer exports pass through the Strait of Hormuz. With the recent conflicts, gas shipments have fallen, raising prices and raising alarms about a possible food crisis. For Latin America, an agro-export power but highly dependent on imported fertilizers, the project works as a “structural hedge” against geopolitical volatility. The financial milestone that Wall Street observes. Atome managed to close a financing package that includes $420 million in debt and $245 million in equity. This backing comes from development lenders of the caliber of the International Finance Corporation (IFC) and the European Investment Bank (EIB), along with specialist hydrogen investment fund Hy24. “We have shown that you can actually close and finance a green fertilizer facility on an industrial scale. It has never been done before,” Mussat said. For his part, Pierre-Etienne Franc, executive director of Hy24, explained to the press that having cheap and non-fossil energy sources offers “a route to green fertilizer that will be localized”, making the industry independent of raw material prices dictated by natural gas. The technical feasibility. Green hydrogen has historically been too expensive to compete with its fossil counterpart. However, Paraguay’s competitive advantage changes the equation. The Villeta plant will operate with electrolyzers large-scale powered by the Itaipú hydroelectric dam (shared between Paraguay and Brazil). According to the company’s projections, electricity costs will be just under $30 per megawatt-hour under a long-term agreement. This technical and economic feasibility was enough to convince the Norwegian fertilizer giant, Yara International, to sign a binding contract of 10 years to purchase the entire production of the plant, estimated at around 260,000 tons per year, a detail exhaustively covered by the industrial press. The view from Asunción. For decades, Paraguay has exported its surplus energy generated in Itaipú to its neighbors, Brazil and Argentina, at very low prices. For the local pressAtome’s installation represents a historic paradigm shift. It means taking that clean energy and using it within the national territory to generate local jobs and produce a good with high added value. Although Villeta will represent less than 1% of the global nitrogen fertilizer market when it begins production in 2029, its backers and market observers agree on something fundamental: if the Paraguayan model works, it could become the definitive template for freeing global agriculture from its dependence on fossil fuels.

We thought that quenching hunger with Ozempic was the definitive remedy against obesity. Until we look at the muscle

by

The revolution of drugs as they are OzempicWegovy or Mounjaro have undoubtedly marked a before and after in the approach to obesity, which previously went under the knife when measures focused on lifestyle changes failed. A priori, we are sold the idea of ​​having a very pronounced weight loss, but the reality is that many patients are falling into protein malnutrition and losing a large amount of muscle mass. We are getting more data. We do not know the drugs completely when they begin to be marketed, but as patients use them, they emerge. new side effects or situations that pharmaceutical companies had not initially imagined. Here a revealing new studywhich will be presented at the European Obesity Congress, has put figures on these effects of malnutrition that accompany successful treatments. And all this indicates that the strategy followed with Ozempic must be changed so that doctors can give precise indications of the nutritional strategy that must be followed during the treatment period to avoid serious health problems. Not having an appetite is bad. A priori, those who take Ozempic want to have less desire to eat, and for it to practically be a task that becomes an obligation in order to survive. But the problem is that people end up having too little hunger, as a new scientific study has shown. analyzed over 5,700 days of nutritional data of 332 overweight adults between July 2025 and 2026. What was seen. Of all of these, the 116 users who were taking drugs like Ozempic consumed drastically fewer calories than the control group, something that was quite expected, but the most important thing was the protein intake that plummeted when the drugs were taken. Specifically, medicated patients consumed an average of 53.8 grams of protein per day, and adjusted to their body weight, this amounts to just 0.6 g/kg/day. To put it in perspective, 88% of these patients fell well below the official recommendation of consuming 0.8 g/kg/day of protein, and far from optimal levels for preserving muscle during weight loss. The reason. Lack of hunger literally makes people skip meals, basically because they do not have that physiological need to put anything in their mouth. Here the study could see that patients taking Ozempic or similar skipped 40.4% of dinners, 31.3% of breakfasts and 30.5% of lunches. In this way, by reducing eating to a few moments of the day, it is almost impossible to achieve the around 25 grams of protein per meal that the body needs to synthesize new muscle and maintain the structure it has. It has consequences. In medicine, the fact of losing muscle mass is what is called sarcopenia and until now it was mainly associated with people who were not physically active, such as the elderly or those who were bedridden. Here scientific reviews suggest that between 25% and 40% of all the weight lost by users taking Ozempic is muscle. And in a very important proportion with respect to fat loss, making it so that almost for every two kilos of fat lost, one is muscle. In older adults or patients with type 2 diabetes, the situation is even more serious, since high doses of semaglutide accelerate sarcopenia, reducing vital metrics for longevity and quality of life, such as grip strength or walking speed. In addition, severe calorie restriction brings with it deficiencies of micronutrients such as vitamin D, vitamin B12 or iron. How to avoid it. Here, medical guidelines increasingly point to a personalized approach in which a highly nutritious diet is established to prevent the patient from having a macronutrient deficiency while losing weight. This is why it is already being recommended that during weight loss it is recommended to increase protein consumption from 1 to 1.6 grams of protein per kg of weight, prioritizing a minimum of 20-30 grams at each meal. In addition, a ban should be established on skipping meals, with eating times having to be very measured, even a little, but at different times throughout the day to avoid prolonged fasting. Maintain muscle. This should be the primary objective and that is why, along with a diet rich in protein, strength exercise with weights, bands or even calisthenics should be encouraged. In this way, the body has the signal to maintain the amount of muscle despite the fact that there is a loss of fat due to the medication. And here the objective is to lose weight, but without having to remove the bricks that are literally building our body, since if we manage to lose weight, but are left without muscle mass, the quality of life is not going to be the best.

We have been avoiding the definitive energy crisis for months. Iran’s missile at Qatar’s largest gas plant threatens to detonate it

by

We had been holding our breath for weeks, assuming the logistical tension in the Strait of Hormuz like the new normal. However, the war has crossed an irreversible red line. We have gone from a trade blockade to the physical destruction of the world’s energy engine, and the consequences are already being felt in the global economy. The impact has been immediate. The price of natural gas in Europe (the TTF reference contract) has shot up 35% in a matter of hours, resurrecting the worst ghosts of the Ukrainian crisis of 2022. The magnitude of the disaster is such that Susan Sakmar, a professor at the University of Houston, warns in Bloomberg that this attack could be “a turning point for the LNG sector, similar to the attack against Nord Stream or perhaps even worse”, as it is a sudden interruption with no signs of a short-term solution. The chronological climb. To understand how we got here we have to look at the chain of events of the last 48 hours. The original trigger, as revealed The Wall Street Journalwas an attack by Israel against the South Pars field, the jewel in the crown of the Iranian energy industry, with the aim of suffocating the sources of financing for the Revolutionary Guard. And it is not just any objective. The analyst Joaquín Coronado emphasizes that South Paris (shared with Qatar, where it is called North Dome) is the largest natural gas field in the world, hosting 10% of global reserves. 70% of Iranian domestic consumption gas comes from there and generates 80% of the Qatari State’s income. A withering response from Tehran. As pointed out Financial TimesIran launched ballistic missiles against the giant Ras Laffan industrial complex in Qatar, the largest liquefied natural gas (LNG) facility in the world and home to key infrastructure such as Shell’s Pearl GTL plant. State-owned company QatarEnergy confirmed “extensive damage” and fires at its facilities. Panic spread throughout the Persian Gulf. According to Reutersthe Iranian Revolutionary Guard issued public evacuation orders, declaring vital energy facilities in Saudi Arabia (such as the Samref refinery and the Jubail complex), the United Arab Emirates (the Al Hosn gas field) and Qatar as “legitimate targets.” Shortly afterward, Riyadh intercepted missiles aimed at the Saudi capital. The market has felt the blow. Oil prices have gone crazy. As detailed oil price, a barrel of Brent surpassing the barrier of 110-113 dollars, which represents an increase of almost 60% in this month of March. However, the real problem goes beyond the daily price. Martin Senior, of Argus Media, warns of a “new level of impact”. It is no longer just about the logistical closure of the Strait of Hormuz (through which 20% of the world’s oil passes); The problem is that the time to repair these destroyed facilities could last much longer than the war itself. And the worst omens already have figures. As has revealed exclusively in Reuters CEO of QatarEnergy, the Iranian attack has knocked out 17% of the country’s LNG capacity for a period that could last up to five years. The domino effect. This situation is taking third countries on their way. As explained CrownedIraq has suddenly lost 3,100 megawatts of electricity due to the Iranian supply cut, while Türkiye will be forced to compete fiercely for emergency LNG shipments. In Europe, the panic is evident: the bulletin Europe Express of the Financial Times reveals that war has blown up the EU leaders’ summit in Brussels, where debate on how to improve competitiveness has been completely overshadowed by fear of energy bills and domestic pressure on the emissions trading system. Geopolitics to the limit. Diplomacy appears broken and America’s allies are losing patience. According to the Wall Street JournalArab governments are “furious” because they feel that the US and Israel strategy has put a target on their backs. For its part, Al Jazeera includes the statements of the Saudi Foreign MinisterPrince Faisal bin Farhan, who has warned Iran that the Gulf’s patience “is not unlimited” and they reserve the right to take military action. Qatar, for its part, has expelled the Iranian diplomats, giving them 24 hours to leave the country. In the midst of this chaos, Washington’s role is erratic. President Donald Trump went to social media to deny prior knowledge of the Israeli attack on South Paris. However, how to collect WSJ, Trump issued an ultimatum to Tehran: if it attacks Qatar again, the US will “massively blow up the entire” Iranian oilfield. Faced with rising prices, the White House is seeking desperate measures. The column of Javier Blas in Bloomberg reveals a controversial plan of the US Treasury: to intervene directly in the financial markets by betting on the downside (shorting) in oil futures to artificially make gasoline cheaper before the elections. An idea that experts such as the CEO of CME Group describe as a “biblical disaster” that would destroy confidence in the free market. The peripheral context. To get the full picture, you have to look beyond the explosions. Verisk Maplecroft Analyst warn in Reuters that the greatest danger right now is that the attacks will extend to Saudi Arabia’s East-West pipeline or to Red Sea ports. These were the only viable alternative routes to avoid the blockade of the Strait of Hormuz, through which 20% of the world’s oil normally transits. In an attempt to cushion the blow domestically, the Trump administration has temporarily suspended the century-old Jones Act (Jones Act) for 60 days, allowing foreign-flagged ships to transport oil and gas between US ports to reduce costs. The dead end. The panorama is bleak. As they reflect on Five Daysthe apparent lightness with which this conflict has developed has dragged us into a dead end. Iran has shown that it does not need to win a conventional war; It is enough for him to set the energetic heart of the planet on fire. Even if a ceasefire were signed tomorrow and ships sailed freely through the Strait of … Read more

We have been believing for years that intermittent fasting is the definitive weapon to lose weight. Science has another idea

by

During the last years, the intermittent fasting has gone from being something exceptional to becoming a nutritional strategy that there is more and more talk and that it has more followers behind it. And it is no wonder, since the promise is quite seductive as it does not focus on what you eat, but on when you eat, activating different metabolic switches to accelerate fat burning. Although there are also detractors behind. New data. The Cochrane library, considered a great world reference, published a few days ago a great review about intermittent fasting that acts as a bucket of cold water, since it suggests that this diet does not offer superior benefits to conventional weight loss diets. The backup. We are not talking about a small study whose validity can be questioned, but in this case the Cochrane researchers analyzed 22 randomized controlled trials that added up to a total of 1,995 participants. overweight or obesity. The objective here was to compare different fasting modalities, such as going 16 hours without being able to eat with eight hours of eating, fasting on alternate days or 5:2 diet compared to classic calorie restriction or inaction. What they found is that, when pitting intermittent fasting against regular dietary advice, the difference in weight loss is virtually zero. The data. Getting into the matter, when intermittent fasting was compared With standard calorie-restricted diets, the mean difference in weight change was a minuscule -0.33%. This difference can translate into that intermittent fasting may result in little to no difference in weight loss with the traditional method. Regarding quality of life, such as the feeling of energy, no difference was seen and, regarding the levels of total cholesterol, HDL cholesterol and triglycerides, fasting did not prove to be a panacea either, yielding results of “little or no difference” compared to the control diets. The small print. One of the most critical points of the Cochrane review is the certainty of the evidence, which they rated mostly as “low” or “very low.” This does not mean that the studies are poorly done, but rather that there are important limitations, such as risk bias, inconsistency in results, and lack of precision. But there is one fact that should worry anyone who decides to opt for this diet independently, without medical advice, since, although the evidence is uncertain, some studies pointed to associated side effects specifically to fasting. These include headaches, nausea, cold intolerance or even insomnia and lack of concentration. What is not yet known. Perhaps it is the most revealing thing about this scientific study, since there are still many unknowns surrounding intermittent fasting that invite further research. In this case, none of the 22 studies included data on “patient satisfaction,” which is important because we don’t know if people prefer to go hungry for a few hours in exchange for eating more later, or if they hate the process. And being comfortable with a diet is essential so that you don’t abandon it halfway through. In addition to this, none of the studies pointed to the relationship that may exist in chronic diseases that require significant dietary control, such as diabetes, and which is very common in the population. But one of the big problems in science today is duration, since most studies lasted less than 12 months. We don’t know if fasting is sustainable or safe beyond a year. It is not a miracle diet. What we do know is that intermittent fasting works, but the key point is that It is not superior to the tools we already had as a calorie restriction accompanied by a balanced diet and exercise. For the average patient, this is actually good news: it means that the The best diet is the one you can stick to. If someone finds it easier to skip breakfast with a 16:8 fast than to count calories at each meal, fasting is a valid tool. But if fasting causes headaches, you’re not missing out on any “magic” metabolic benefits from eating three times a day. Although in this process the most important thing is always to be advised by personnel who are qualified in nutrition to be able to have the best dietary plan, to have real objectives and, above all, not to get frustrated along the way.

In 1925, procrastination was already a problem and someone found the definitive solution: the isolation helmet.

by

Hundreds of thousands of years of evolution They have turned modern humans into perfect machines in one thing: distracting us. No matter where, when or how you are, if you are accompanied or alone, if you are waiting in line at the butcher shop or have a book in front of you, chances are that your attention ends up dispersing for any nonsense. Maybe the flight of a fly. Maybe that sound you just heard in the next room or a stain on the wall. It happens today and it happened a century ago, when a science fiction-loving inventor designed the ultimate machine to end distractions. His patent dates back to 1925, but it addresses a hot topic: procrastination. The war of wars. Since man has been a man, he has done two things, both wonderfully: he is distracted and he procrastinates. Almost 2,000 years ago Seneca warned us about the risks of wasting our time and we know, for example, that distractions were one of the big concerns of the monks of the Middle Ages. Some even thought that if our minds disperse it is due to the influence of devils. In 2026 things are not very different. A quick Google search comes up to find a wide (very wide) list of guides and videos with tips on how to focus and stop putting off tasks. And it is understandable. After all, cell phones, social networks and other inventions of modern technology make our lives easier, but they have been filing our ability to focus. Even science has confirmed that we are losing the ability to focus among so many stimuli. And how do we solve it? We humans have not only been distracted for centuries and centuries. We have also spent some time looking for ways to avoid that annoying wandering of thoughts. Of all the solutions that have been given to the problem, perhaps the most astonishing (and bizarre) is the one proposed just a century ago by Hugo Gernsbachan imaginative Luxembourgish-American inventor. His name may sound familiar to you because, in addition to register patents of inventions and working in the electronics industry, Gernsback excelled in another field: publishing. Throughout his life he promoted several magazines focused on technology (RadioNews), but he also shone in science fiction. We owe him Amazon Storiesa milestone of the genre. His contribution in the field was so important that he is considered one of the parents of science fiction (with permission from Verne and HG Wells) and every year he is honored through the Hugo Awards. Adding facets. A century ago Gernsback combined this double facet, his technical ingenuity and overflowing imagination, to launch a proposal through the pages of Science and Inventiona magazine specialized in technology. In its July 1925 issue, the inventor, editor and novelist presented a creation which he named ‘The Isolator’. The name is striking in itself, but it pales in comparison to the photographs that illustrate the report. They show Gernsback working in his office with his head in a gigantic diving suit, an elongated helmet with two small openings for the eyes and a tube that connects it to an oxygen cylinder. Its purpose: to immerse the wearer in absolute isolation, an ideal state for centering. When silence does not come. Gernsback came to a conclusion very simple: sometimes it is not enough to lock yourself in a room without noise to concentrate. Even so, we risk our mind getting carried away by the flight of a fly or starting to wander after seeing a stain on the table. The way to avoid it, he concluded, was to eliminate all those influences “in one fell swoop.” As? With a helmet prepared to suppress unnecessary noises and visual stimuli. For the first thing, the noises, Gernsback decided to go for a robust multi-layer helmet. Its first prototype was made of solid wood with an internal and external layer of cork and a felt trim. For the second (view) he added three small pieces of glass. The design was completed with a device at mouth height that allowed the user to breathe without noise creeping in. The result, says the inventorit was a helm with an efficiency of “about 75%”. It isolated from external noises, but not completely. There was room for improvement. And how did you improve it? Perfecting the design. Gernsback rethought the material and added an air chamber so that the efficiency of ‘The Isolator’ rose to 90 or 95%, “eliminating practically all noise.” So that vision was not a problem either, the helmet’s glass peepholes located in front of the eyes were painted black, leaving only a narrow transparent strip. “When the two white lines on the glass open, the field through which the view can move is relatively small,” points out the inventor. “It is almost impossible to see anything but a sheet of paper in front of the user. There is no distraction.” Concentrating… and breathing. It is one thing that ‘Isolator’ lived up to its name by isolating the user in a bubble of responsible concentration and another, very different, that it was comfortable or even bearable. The author explains that after 15 minutes with it on the user “experienced some drowsiness”, so he decided to improve the breathing system, connecting it to a small oxygen tank. This improved breathing and “revitalized the subject.” In his article Gernsback added detailed plans of ‘The Isolator’ and even a sketch of an office with a complete distraction-proof installation, which included a ‘noise-proof’ door and an adequate ventilation system. “With this provision you can contemplate an important task in a short time,” boasted. “Building ‘The Isolator’ will be a huge investment.” The power of paper. If humanity has also learned something (including Gernsback) it is that paper supports ideas that are not supported in reality. His helmet may have been eye-catching, it may have even worked, but it didn’t work. We don’t know to what extent its inventor really expected it … Read more

A YouTuber has gutted all the consoles to create the definitive machine: the Ningtendo PXBOX 5

by

Although the PC is the almost perfect cross-platform machineuntil not so long ago, if you wanted to enjoy all the video games you had to have a PS5a Switch 2 and one Xbox Series. The problem, apart from many others, is space: they take up an awful lot and They are not the most “aesthetic” machines.. A Chinese YouTuber has the solution: the Ningtendo PXBOX 5. It is the perfect fusion between the three, and the secret of how it works is in a 2013 Mac. As Jack the Ripper said. Let’s go in parts. We have seen many projects that change the functionality of a console or even turn a PC into a coffee makerbut what the YouTuber has proposed is much more ambitious. To address the space problem, it has united the three consoles into a single tower that, on top of that, is no more bulky than a small PC case. And the first thing is to gut the machines. Image | 小宁子 XNZ At this point, the YouTuber realized the most important thing: without the case, the key parts of the three machines are the fan, the power supply, the aluminum and copper heatsink… and the board, obviously. All components are soldered on the board, so you don’t have to worry about GPU, CPU or RAM memory. Switch 2 is on the sidelines for the moment. For PS5 and Xbox Series X, the essential thing is each one’s board and the rest can be shared. A single supply for both, a single heatsink and a single fan. But… how? The key? Apple. Well, precisely, one of Apple’s most famous computers has the answer. The Mac Pro ‘Trash’ is the 2013 model that has gone down in history for being a complete disaster. I still find its design beautiful, but Apple went overboard with a triple PCB and dual GPU configuration. Precisely, it is the idea he has in his head, so it comes in handy. Inspiration in the Apple heatsink Because? Because Apple designed a double PCB system on a central aluminum heatsink. This way, you can inject fresh air through the heatsink, expelling heat through the top and keeping the plates cool. The question now is how to make an aluminum heatsink that cannot be bought on the market and that would not be viable to print directly on metal (due to costs). Ancient 3D printing technique. Inspired by a wax casting technique from hundreds of years ago, the YouTuber created a heatsink model on a 3D printer. To do this, he used a material called PLA that vaporizes when it reaches a certain temperature. With the PLA “sink” in hand, he wrapped it in plaster and burned it in a 700-degree oven. The PLA mold. Image | 小宁子 XNZ Thus, the plaster remains while the PLA dissolves, allowing an internal structure to remain that can be filled with aluminum. It sounds simple, but he had to remove the air from the plaster with a vacuum machine, melt the aluminum and have an oven that carries out a complex process of dehydration, pyrolysis and combustion for 12 hours to achieve the result. The first attempt at a heatsink turned out okay. Image | 小宁子 XNZ The heatsink already polished. Image | 小宁子 XNZ Then, he “simply” added the aluminum and… the first try didn’t work. Unlike Chinese artisans centuries ago who if they lost a piece they had to re-carve the wax mold, here they simply 3D printed another one and repeated the process. After filing the aluminum, the heatsink was ready. Switch 2 not so much. Place the PS5 Pro and Xbox Series Wi-Fi and Bluetooth of each one (for Internet and connection with accessories) and you connect the only power supply that gives life to both consoles in the base. Switch 2 is a little more complicated. It doesn’t need as much food, so opt for a USB-Cbut also for printing a module that does not sacrifice the mobility of the console. The dock of the new Switch 2 dock.

To do this, he devised a module similar to the dock, but to be placed vertically. The button that ejects the Switch 2. Image | 小宁子 XNZ After trying several conventional springs, the YouTuber printed some in 3D to ensure that, by pressing a button, the console slides as if it were toast so that it appears from the side. It sounds dangerous, but seeing the result, the truth is that the movement is quite smooth. Arduino to the rescue. With all the machines connected to the power, the most important thing remained: program a brain to control the HDMI output and the power. To do this, he used a plate Arduino Conveniently programmed so that, by pressing a button on the top, the signal switches between platforms in less than five seconds. The aluminum heatsink and the copper ones that go directly to the APU of the two consoles with the thermal paste. Image | 小宁子 XNZ Mounting the plates on the heatsink. Image | 小宁子 XNZ It’s not the only thing it does: it also has a front LED connected that changes color (red, blue and green) depending on the console it is running (Switch 2, PS5 or Xbox Series X). Connecting the Arduino board and the Image LED strip. | 小宁子 XNZ THE console. And that’s it, let’s play. The speed at which it changes between the HDMIs is impressive and the creator herself is surprised by the heat it expels through the upper area. Obviously, there are two ‘large’ consoles dissipating the heat and having an aluminum heatsink that, no matter how apparent it may be, has somewhat thick tabs for what is usually … Read more

Gemini 3 has left all its competitors behind. It’s Google’s definitive punch to the table: Crossover 1×32

by

Three years ago, panic on Google. The launch of ChatGPT made Google will declare a “code red” before an AI model that proposed a clear revolution and a clear threat to the search business. Sundar Pichai began to make moves, but the truth is that the first movements with Bard They were disastrous. There were more problems and blundersbut since then Google’s trajectory has been spectacular, and its AI models have not stopped achieving success. We saw it with Gemini 2.5 Pro and with Nano Bananabut now they have proven it again with Gemini 3which has managed to become the model with the best features in most areas, at least according to the benchmarks offered by the company. It is somewhat surprising, especially considering that OpenAI seemed to have controlled the market with a ChatGPT that continues to be more popular but is little by little being cornered by the competition. In fact Google seems to be doing everything right lately in this area. DeepMind is the great reference for “serious AI”and Google’s enormous resources—which has its own cloud, its own chips, and its own model—point to a bright future for this company. We talk about all of this precisely in this episode Crossover 1×32 in which we review those hesitant beginnings of Google and how the company has managed to get rid of its fears to bet everything on AI. That in itself is surprising, because that bet is also risky for them. Exciting times! On YouTube | Crossover

The definitive jump towards the total control of the iPhone

by

Apple has presented the N1 chip next to the iPhone Airthe thinnest phone in its history with only 5.6 millimeters thick. Why it is important. The N1 manages all the wireless connections of the iPhone: Wifi 7, Bluetooth 6 and Thread. It is the last link in Apple’s strategy to internally design each iPhone component, from the main processor to the modem. The context. Apple has been replacing third -party components with own chips for years. First were the processors to replace Intel. Then came MODEM C1 (now C1X) that displaces Qualcomm. Now the N1 eliminates Broadcom dependence and other wireless chip manufacturers. Between the lines. The obsession with total control is no accident. Each own chip allows impossible optimizations with external components, better benefit margins and elimination of Royalties. Apple promises that N1 improves functions such as Airdrop And the mobile access point, something difficult to get with standard solutions. The threat. For traditional suppliers, each Apple chip is lost territory forever. Broadcom, who dominated this segment, loses one of its most lucrative customers. The employer repeats: Apple develops internally, optimizes for your needs and never goes back. And now what? The N1 debuts on the iPhone Air, but will reach the rest of the range. Apple has shown that when a technology dominates, it extends it to all its products. Absolute hardware control is the basis of its competitive advantage.
