Testing Tiktok’s most viral anti -manners seemed like a good idea. Until I did

by

I am one of those people who, if there are twenty people with me and a single mosquito, will chop me. They worship me, what am I going to do? I actually try to do everything I can, because in addition to the standard itch, it makes me reaction and the bites are put ON FIRE. The Tiktok algorithm must know, because they often appear to me trick videos to prevent mosquitoes from picing you, All homemade, super simple and, according to their creators, infallible. Without too much faith, I chose the three that seemed more interesting and I prepared to try them. Everything is for science. Why mosquitoes bite us First of all a little science. The main reason why a mosquito chooses a dam to chop it is the blood group. It has been proven that people with type 0 blood have More lactic acid in the skin And this attracts mosquitoes more. But this is not the only factor, so is Carbon dioxide What do we emit. Mosquito females, which are the ones that bite, can smell the CO2 60 meters away. If our body temperature is also higher, for example by making an effort, we are the perfect target. Tiktok to the rescue During the summer, in my bag you can not miss the repellent spray, it is the only thing that works for me, but of course, it is not the most pleasant in the world because it smells very strong and leaves your skin as sticky. Over the years I have tried all kinds of things Like citronela candles, smoke spirals, repellent bracelets (luck if someone pretends not to pique a mosquito carrying one of these) and I have even planted citronela at home. Let’s see if Tiktok experts save me from this cross. Trick 1: Simple and with surprise He First trick I tried is the simplest. You just have to put half a liter of cleaning vinegar in a glass boat and add a lemon cut into slices. It smells a bit strong, but it doesn’t smell bad and it is quite decorative. I put it in the kitchen, which is where more flies and mosquitoes usually enter because the window is usually open and I waited. To my surprise, the best of all. A few days later I had my verdict in the form of three new bites. It does not seem to have a lot of the mosquitoes, but to my surprise it had an unexpected benefit: I barely saw flies. In the video they say that it is effective against flies and mosquitoes, but my perception is that, to work, it only works for the first. Nor does it look like a very durable method and after a few days it smelled. It would be necessary to renew it to maintain the effect. Trick 2: The spiritual In This video We receive a soft voice that promises that the trick will end with flies, mosquitoes, mosquitoes and cockroaches. A complete. The method consists of taking a glass bowl and putting coffee poses, half a cup of flavoring, clove and a wick of a candle. Must burn for an hour And our expert ensures that we will never see an insect again. Run, take the photo that goes out! In the explanation of the recipe I already began to lose faith because it does not even explain what that of the aromatizing is, so I had to skip that step. The truth is that I cannot say whether or not it is effective because I did not get the fuse to burn more than 1 minute in a row. I tried several wicks and nothing, when I arrived at the coffee he went out (and that was dry). From what I have read in the comments, the same thing happened to many more people. Of course, it smelled very well. Trick 3: The scientist He said that one of the reasons why mosquitoes are biting us is because of the CO2 that we emit and is precisely the basis of this trick. In the video it explains us How to build A carbon dioxide trap With water, sugar, yeast and a cut plastic bottle. The result is quite horrible from the decorative point of view, but it also smells weird. I gave him a vote of trust because it is the method that had the most scientific basis. A beautiful If I have to summarize the result in a word, it would undoubtedly fail. In the time I had the trap placed Not only did they chop me mosquitoes, it was not even one. In the comments of the video there are people who had similar results and also point something striking: at no time in the video teaches us the mosquitoes that have fallen into the trap (for whatever). I threw it three days. What does work and is endorsed by science I didn’t have much faith and my suspicions have been confirmed. None of the three methods have freed me from mosquito bites, but there are remedies that free us with a much higher success rate, mainly the Industrial repellent with Icaridin and Deet As an active substance. The DEET is the most common ingredient in the repellent spray. With a 20%concentration, it is effective in protecting us for 5 hours. The bad thing is that It has greater toxicity. He IR3535 It is a bit softer and equally effective against some mosquito species, although it would not be so much against others that transport dangerous diseases. There are also natural alternatives such as Essential oils of mint, basil or citronella that are much more respectful of the skin, the problem is that the softer, less effectiveness. Putting chemical substances on my skin is not excited, but they are the only thing that I am not going to end up bitter by itching. In addition, we must not forget that Mosquitoes are considered the deadliest animal that … Read more

Samsung’s triple folding did not appear in the Unpacked. The good news is that it will not take long to see it

by

Samsung’s unpacked left us with a whole new range of folding devices. The fold7 and flip7 They were the protagonists of the evening, also hollowing the Flip7 Fe and the new ones Samsung Galaxy Watch8. However, we stayed with the thorn stuck to know more about that rumored Triple folding of the firm. The good thing is that we will not have to wait for much more to know about him. Official confirmation. Roh Tae-Moon, responsible for the Samsung device division, has declared that he hopes to launch the ‘Trifold’ phone before the end of the year, he mentioned the media The Korea Times. “We are working hard on a Trifold smartphone with the aim of launching it at the end of this year,” the executive explained. The company is now focused on perfecting the product and its usability, although they have not yet decided its final name. A new member joins its folding. Samsung has been dominating and popularizing the folding smartphones market, which initially generated skepticism in the industry when they made an appearance For the first time in 2019. Now these devices have become an important segment for the company’s brand image, and the technological giant wants to continue marking the rhythm. The Trifold would represent the next natural evolutionary step after the popular Galaxy Z Fold and Z Flip. Three folds, three sizes. The device would allow three different configurations: as a traditional smartphone, as a tablet when partially deployed, and as an even bigger screen when completely opened. It would also allow you to use one of the three faces as a support for a surface. Although it is rumored that it could be called Galaxy G fold, Samsung has not yet confirmed its official name. The company He gave little clues of this concept in January during its unpacked event, and several internal files of One UI 8 suggest that its development is advanced. The competition has aroused Samsung. The Korean firm is not alone in this race. Huawei already markets your Mate XTthe only trifold currently available in the market. Another Samsung executive who did not reveal his name, commented to the environment Android Authority That the company has the design ready and could “put it in production”, but that they must first identify a clear “purpose” for this new factor of form. “We have been with a trifold, designed and everything. What we are discussing is viability. Is there really demand for this form of form?” He explained. And now what. The launch of the Trifold would also be framed in Samsung’s strategy to create optimized devices for artificial intelligence. The company considers that smartphones are no longer only tools, but are becoming “colleagues” who see, understand and respond to what users are seeing in real time. Samsung plans to take the functions of Galaxy AI at 400 million galaxy devices that exist in the world before the end of the year. Cover image | Samsung In Xataka | Best folding mobiles in 2025.

Some scientists have rowed 225 kilometers in 45 hours between Taiwan and Japan. It seems absurd but there are good reasons

by

In 1947 the Norwegian explorer and ethnographer Thor Heyerdahl He had an idea To demonstrate that the former inhabitants of Peru were able to navigate to the coasts of Polynesia in pre -Columbian times: to manufacture a rudimentary raft and cover the journey himself. Sounds crazy, but experience went well and seems to have created school, like He has just demonstrated An anthropologist determined to reveal how humans were managed to travel between the coasts of Taiwan and the islands of southern Japan. Along with the rest of his colleagues he has chosen to follow the footsteps of Heyerdahl, manufacture a cedar canoe with tools from the Paleolithic and then launch to the Pacific waters. When, where … and how. Researchers who are dedicated to studying the first human settlements in East Asia have a rather accurate idea of ​​when and where the first migrations were made, but there is a question that still takes away their dream: how noses they moved? How did they travel through sea, raffling waves, winds and currents, with hardly any resources? How did the first settlers manage to arrive for example do 30,000 yearsTo the island Yonaguniin the archipelago of The Ryūkyūcurrent Japan? After all, Taiwan is more than 100 kilometers and the distance is even higher from the continent. “Simple questions”. That kind of questions are what the anthropologist was asked a few years ago Yousuke Kaifufrom the University of Tokyo. During his investigations in the deposits of the Okinawa Islands he found vestiges that give away that there were already humans in the region 30,000 yearsbut nothing that clarifies how they got there. “There are stone tools and archaeological remains, but they do not answer those questions,” confesses to The Guardian. That there were no evidence did not mean that Kaifu and his colleagues could not raise hypotheses … and demonstrate them. “We started this project with simple questions: ‘How did the Paleolithic peoples arrive at islands as remote as Okinawa?’ ‘How was your trip difficult?’ ‘What tools and strategies did they use?’ ” remember The Japanese anthropologist. “Archaeological evidence, such as vestiges and artifacts, does not offer a complete vision, since the sea, by nature, drags them. So we turn to experimental archeology, in a line similar to The Kon-Tiki expedition of 1947 of the Norwegian Thor Heyerdahl “. In the skin of the ancestors. Like Hayerdahl and his mythical expedition Kon-Tiki, Kaifu and his colleagues assumed the complicated task of putting themselves into the skin of their ancestors of thousands of years ago. How did they travel? How did they guide themselves? What materials did they use for their vessels to draw the currents of the region? First they tested with Juncos balsas and bamboo, but ended up ruling out the idea. With these materials they obtained too slow ships to overcome The Kuroshioone of the strongest sea currents and that conditions navigation in the northwestern Pacific. His next option was to try a canoe made with Japanese cedar, such as those used in the area thousands of years ago. In order for the experiment to be as faithful as possible to reality, the researchers talled a cedar one meter thick with stone axes and then carved it until opening a cavity inside and giving the shape of a canoe of 7.5 meters of length. The result was ‘sugime’, a boat not very different from those used thousands of years ago. In 2019, after waiting for the sea to calm down, a team of five crew (in which scientists and remakes were included) rose on board and tried it. And how did they do it? As the Paleolithic men, without GPS or any other modern navigation device, would have done only by the stars, the sun, waves and instinct. The expedition started from Taiwan Rumbo Yonaguni, in Kyūshū. The island is not visible from the Taiwanese coast (and in fact it was not for much of the journey, when it was hidden from the waves), but the scientists verified that on clear days it is not difficult to contemplate it from the mountains of Taiwan. Hence the populations of 30,000 years ago they met her. The raft left in July 2019 and its crew had to row more than 45 hours and cover a journey of 225 kilometers before reaching its destination. It was not easy, but the team reached Yonaguni to the second night, reinforcing the theory that thousands of years ago the first Okinawa settlers were able to travel in Canoas from neighboring Taiwan. During the syglura, yes, They suffered crampspain and hallucinations and even were forced to Browse water Often to prevent the raft from getting causing. “They achieved something extraordinary”. The experiment was completed in July 2019 thanks to the support of several institutions but has not achieved authentic impact so far, when the University of Tokyo He has revealed The experience. The reason? A few days ago there was a documentary about the trip and two academic articles published in Science Advances. In one the experts report the 45 -hour experiment between Taiwan and the island of Yonaguni. In the other they share virtual recreations hundreds of possible routes to know which could be the “most plausible”. “The general public usually considers the Peoples of the Paleolithic as ‘lower’, mainly due to their ‘primitive’” culture and technology, ” collect the report. “In marked contrast, our experiment has shown that they achieved something extraordinary with the rudimentary technology they had.” The experiment also confirms the growing interest in archaeological reconstructions and tests with boats that copy old models, something that (in addition to the case of Hayerdahl) we have seen in Indonesian research, France either United Arab Emirates.

Google’s compact has very good arguments, although not everything shines the same

by

What if they told you that the cheapest mobile of Google of current generation has the same chip as its high range and that you will receive updates until 2032? On paper sounds very good, but another thing is to live with him for weeks. In a new one 24/7 of the Xataka YouTube channelwe have tested the Pixel 9a To verify how it yields, how it behaves in the day to day and if your camera remains the greatest claim. The first week makes it clear where the shots go. “The experience is being one of the most comfortable I’ve had with a phone in a long time,” says our partner. It is a manageable mobile, light and thought to be used with one hand. The 6.3 -inch OLED screen has 120 Hz and good brightness to exterior soda rate. But there is a design decision that attracts attention: “It seemed that we had overcome the great frames with Pixel 9, but they have returned in this middle range.” The 9A pixel repeats processor: mounts the same G4 tensioner than the most expensive models. So why sometimes seem to go slower? “I’ve found some Punctual thyrox or a certain slowness when unlocking the phone or opening some application. ”The device, in addition, arrives with 8 GB of RAM compared to the 12 GB of higher models. Is this combination a problem? Video tests can help us draw a conclusion. Where there are no surprises is in the operating system, which is Android 15. “It is the software that is closest to Android Stock that we can experience, ”he points out. Without aggressive layers or Bloatware, and with a promise that highlights:“ We have 7 years of updates, which would support us until 2032. ”Our partner reflects on whether the mobile will endure so much time. And then there is AI. Circle to Search, Gemini, Gemini Live… Functions that are already integrated into the system. But in practice, they have not had much prominence. “I have not had the need to use any of the Artificial Intelligence Tools”Will it be a matter of habit? Or real utility? In any case, will we know more in the video. In photography, Pixel 9a bets on balance. “He doesn’t want to be the best, but he wants to give us very good results,” he explains. The main sensor offers natural images, with a balanced dynamic range and pleasant blur even without using the portrait mode. That is how some loose points that can be decisive for some users also appear on the scene when choosing this phone or not. The battery improves previous generations. Now we have 5,100 mAh and that shows. “Most cycles will have achieved about 7 hours of active screen.” In practice, it is a mobile that It arrives at the end of the day with marginalthough without overcoming the best rivals in autonomy. Nor does it do so in fast charge: 23 W and something more than an hour to load it completely. Where then does this pixel 9a fit? Is it a recommended mobile? Everything will depend on the user’s needs, but to discover it you can help you in this video that Emos preparing in Xataka and which is already available on our YouTube channel. We invite you to take a look and leave your opinions in the comments. Images | Xataka In Xataka | I had no idea why my phone burned so much in summer.

There is an island that has been prohibiting cars for more than a century and continues to use horses. And it’s doing pretty good

by

Before entering the subject, let’s make a game: Open Google Maps, Type “Mackinac Island” And let the search engine transfer you to a small island in Lake Huron, in Michigan, USA. Then approximate and handle Street View to take a virtual walk through its streets. In their wide avenues you will see people walking, people by bicycle and people mounted in carriages thrown by horses, but what you will not find are cars. Very lucky maybe CACES some (few) of those used promptly to provide certain services. After all Mackinac is known worldwide Therefore: have banished motor vehicles and stay, in the middle of 2025, such as the reign of horses. In a Michigan place … Mackinac is a fantastic example of how history is full of ironies. The island known inside and outside the US for its aversion to cars is located in the middle Ford, General Motors either Chrysler. In fact Detroit, the “Motor City” It is located just 400 k, in a straight line. However, despite this influence of the industry 127 years ago the island authorities made a peculiar decision: they prohibited the use of combustion vehicles. Petarders no, thanks. The veto was promulgated the July 6, 1898after the islanders who dedicated themselves to working with calese alerted of the “dangers” and discomfort that the new “carriages without horses.” The legend He says that the trigger (never better) was the firecracker of a vehicle that in 1898 frightened a group of horses. It is also not far -fetched to think that the chauferes They moved to shield your business in the face of engines. A prohibition in DNA. The fact is that the rule set. After a few years It extended To the rest of the island, just 3.8 km2, and with the passing of the decades it became one of Mackinac’s great hallmarks. Little served to mark like Oldsmobile Or Ford became stronger and more only a few kilometers from there, the small island of Lake Huron remained an impregnable redoubt for the thriving automotive industry and thus has continued to be during the twentieth and twenty -first centuries, for pride of local authorities. On their official website they remember that the M-185the road that surrounds the island, is the only US state road in which the use of motor vehicles is not allowed. “Of the more than six million kilometers of public streets in the US, there is a stretch of 13.2 kilometers in Mackinac that stands out for its uniqueness,” They need The authorities. “It could be decided that it is literally one among one million.” There is no car? No. And yes. The authorities do not allow people to use cars as they would do any other part of the US, but that does not mean that there are certain exceptions. Mlive remember That the island has emergency vehicles, police cars, an ambulance released in 2021 and fire trucks. The State Park also has vehicles, although only uses them out of season high and preferably at first or last hour of the day. The island has also turned a blind eye in certain cases. For example, the US secret service put a car in 1975, during a visit by President Gerald R. Ford with his wife. The vehicle was used by agents. Ford opted for a carriage pulled by horses. Another exceptional case was the filming in 1979 of ‘Somowhere in Time’a film starring Chistopher Reeve and Jane Seymour that was shot in Mackinac and had a special permission to use vehicles. And the rest of the time? Simple. People walk, move by bike or ride in carriages thrown by horses, one of the great hallmarks of the island. It is believed that the horses arrived in Mackinac around 1780 by the British, who used them to lift the Strong Michilimackinacand the caleses were popular mostly in the nineteenth century, when the island became popular as a resting place. The first license for a carriage was issued in 1869. The island also has a ferry that allows its 600 inhabitants Move more easily from neighbors Mackinaw City or St. Ignace. “Without horses, this place would not be what it is. It allows you Michigan’s Upper Peninsula. A destination with history. With the passing of the decades Mackinac has achieved more than becoming a small redoubt safe from the traffic and contamination of cars. It has also become a popular destination, especially during The summer months. There, in addition to their horse carriages, coasts and landscape The Anishnaabe culturea group of indigenous peoples from the region of the Great Lakes of North America.

The United States has decided to launch millions of flies with airplanes on its own territory. It has good reasons

by

As killing flies to guns, in the United States they have decided to do it using more flies. Literally. For months the country faces the ghost of the Cochliomyia hominivoraxa fly that in its larval state is a serious threat to cattle, wildlife, pets and even Humans. Hence the country has devised a peculiar strategy to fight it: raise thousands of millions of flies and then release them from airplanes. It sounds crazy, but it makes all the meaning. There is no small enemy. At first glance the Cochliomyia hominivoraxalso known as the New World Barrenning Worm (or NWS) does not seem much. But that is with the naked eye, of course. Although they are not much greater than common flies, in their Larval state they represent a considerable threat, especially for cattle, pets and wildlife. NWS females deposit the eggs in wounds or mucous membranes and, once they hatch, the larvae break through the meat, feeding thanks to their sharp oral hooks. Hence “BARRENOR WORD”. Dead cattle in weeks. The species is so voracious that the US Department of Agriculture (USDA) warns of its effects, the risk of cattle and what the nation is played by keeping it at bay. “It is crucial to protect our livestock industry, our economy and our food supply chain,” emphasize. In An interview With the AP Agency, Michael Bailey, director of the American Association of Veterinary Medicine, is even more explicit: the larvae can end a 450 kilos bovine in a matter of two weeks. And why is it news? The boreride worm is An old acquaintance of the American authorities. Although the species is endemic to Cuba, Haiti, Dominican Republic and countries in South America, the US has been looking for a way to prevent the species from expanding north with the help of Panama. Moreover, in his day he already deployed a strategy that allowed him A small outbreak Registered in the Florida Keys in 2017. The problem is that now the larva is calling again at the gates of the southern US, which has put the USDA on guard. “Although the NWS has been eradicated from the country for decades, recent detections in Mexico, at points as north as Oaxaca and Veracruz, about 1,125 kilometers from the border, have led to the immediate suspension of the imports of living cattle, horses and bison in the US entry ports on the southern border on May 11,” I recognized The government recently. Cattle lock and something else. Import blocking is only a small part of the Usda activated plan to curb the expansion of carnivorous parasite. The US authorities also want to have a vast network of facilities that allow him to raise hundreds of millions of NWS flies every week. And are willing to invest millions of dollars to achieve it. The Agriculture Department has already announced the investment of 8.5 million in a southern Texas and other installation 21 million To re -adapt a metapa plant, in Mexico, which was dedicated to the breeding of fruit flies. The idea is that it now focuses on the NWS. Both facilities will also be added to another base of Panama that is already able to raise about 177 million flies every week, a figure that the USDA considers insufficient. Its goal is to get to 400 million. But … raise flies for what? To have fewer flies. I know, it sounds inconsistent, but it makes all the meaning of the world. The flies that leave those hatcheries are not ‘normal’, but special specimens, males sterilized with radiation that can mate, but not (and this is the key) reproduce. The idea is actually very simple: scientists raise millions of flies, billions, and then release them in the fields so that females mate with those altered males. The result are eggs unable to hatch, which translates into less larvae and, over time, in diminishing populations. A solera technique. The technique is interesting for several reasons. For a start, Remember APit is more effective and ecological than resorting to pesticides. In addition, Washington has already proven that the system works relatively well. USDA remember which used the same “biological control technique” to end NWS populations in the 60s and the 2017 Florida outbreak. The same strategy has also been deployed in other places to combat different pests. Los Angeles used it to stop the proliferation of the Fruit fly And Singapore did something similar with the mosquitoes They transmit dengue. ‘Bombing’ of flies. Raising sterile male flies is just the first part of the plan. To work and stop the carnivorous worm, something else must be done: release those diptera strategically. And the US already knows how to do it. The Associated Press agency It has relieved that the government proposes to throw the altered specimens on southern Texas and Mexico. In fact he hopes to have In late of this same year a special installation to disperse insects in the Moore Air Baselocated almost at the border with Mexico. The new farm of southern Mexico would take something more to be ready. It would not be activated until July 2026.

no other great technology is having a stock market as good as she

by

Meta has just achieved something unheard of: dethrone Nvidia as the most successful technological technology of the year on the stock market. It is still far in stock market capitalization, but it grows above it in what we have been for the year. Its +22% surpasses the rest of the great technological, also Microsoft, and confirms the excellent stock market moment in recent times. Why is it important. Less than two years ago, Wall Street was punishing a goal for its obsession with the Metaversosomething that vanished at the same speed at which Chatgpt spread: the future actually passed by. Your expense in Reality labs Nor did it help. Today it is rewarding its transformation towards the practice. In detail. The change of course began in 2023, with what Zuckerberg called “The year of efficiency“ Now goal is running an AI strategy that combines the best of three worlds: Mass consumption products. Ray-Ban MetaCalls, Goal AI. Business infrastructure. Talent capture. In these last weeks we have understood the magnitude of point 3 with The signing of Openai leading researchersincluding Creators of O1 and O3. We also know that it plans to get 29,000 million dollars to invest in data centers. Between the lines. Investors have caught something that seemed unlikely: goal has made their traditional advertising income grow while in parallel builds their future in AI. Your R&D spending will reach the 65,000 million dollarsbut their margins continue to expand. Goal is demonstrating that it is possible to reinvent itself without losing the main business. Meanwhile, Google fights as can against the arrival of Chatgpt and Apple continues to look for its site in the AI ​​race. Goal has defined its identity: being the company that democratizes AI with a Llm Powerful but open source (with nuances) … … and make an incursion into Wearable that seemed innocent but is being tremendously successful. And now what. The next catalyst will be to verify how its smart glasses business evolves. And that of AI attendees. Above all, to what extent they change the business. Meta, first of all, it is demonstrating what was not taken for granted for all great technology: survival capacity in the transition to AI. And that is using recognition in the parquet.

If the question is “How to make a good prompt for AI”, Anthropic has just given us his guide

by

Anthropic, the creator of Claude, has published its definitive guide of Prompt Engineering. A free Bible that synthesizes years of research in practical techniques to get the most out of Claude. Why is it important. The majority of users barely scratch on the surface of what the generative AI can do, leaving below even what could benefit in their day to day, even if they are not engineering uses. The panoramic. The guide covers from the foundations to the most sophisticated. From how to be clear and direct in a request to advanced techniques such as Multishot Prompting or the chains of thought. Culminates with strategies such as the chain of Prompts complex And all enlightened with real examples of Claude. In detail. The nine central techniques of this guide function as a ladder: Clarity and direction. Say exactly what you want. Prompts Vagos produce vague results. Various examples. It shows Claude how to think with several cases of use. Thought chains. Ask Claude to think step by step before answering. XML Tags. Structure the answers with greater precision. System roles. The classic “You are a lawyer”, “You are a data analyst”, etc. To change the chatbot perspective. Prellenate of answers. Guide the tone and format starting the answer. The context. Anthropic explains that many of the problems with generative AI are solved with better Promptsnot necessarily with more powerful models. This is an attempt to democratize techniques that they only knew somewhat more advanced developers. Open the guts of what they know it works. For example. The guide includes concrete examples: Instead of ‘Create a Dashboard’, he writes ‘creates a complete analytical analytical dashboard with interactive graphics and filters’. For code Frontendadds specific modifiers: “Includes soft transitions, micro -interctions and visual effects that demonstrate advanced web development capabilities.” And for complex tasks, the guide recommends using XML labels as to structure Claude’s thought. The difference is in specificity: say exactly what you want produces much better than vague instructions. The AI ​​returns you what you give. Yes, but. There is an important nuance: this guide assumes that you already have clear success criteria and ways to evaluate results. Without that base, even the best Prompt It is a shot in the air. And now what. For developers, this is gold. For the user something else casual, It is worth dominating at least the first techniques for minimizing hallucinations and improving the results. He Prompt Engineeringthat some time ago it seemed a kind of black magic to invoke in a mystical way, it is every time a skill that can be learned, measured and better perfect.

AMD’s problem is not that it does not make good gpus for ia. Is that it is not even close to Nvidia

by

AMD is doing things well, but even doing them still unable to compete with Nvidia. The company has just raised its renewed road map with promising models, but that is not a guarantee of anything to a NVIDIA that will not let its absolute leadership position escape. The problem for AMD is not to be, but get others to take note. IDC consultancy data indicate that Nvidia dominates the AI ​​chips market with 85.2% market dick, for 14.3% AMD. Other analysts like Jon Pedie Research go beyond and According to your data The NVIDIA quota in this segment is 92%. AMD instinct mi350 are just the beginning. The GPUS for IA, which AMD calls “accelerators”, follow its evolution. During the event they presented their family or Instinct Mi350 series with two variants, MI350X and MI355X. According to the manufacturer, these chips are four times higher in general performance with respect to the previous generation, but are up to 35 times more powerful in the field of inference AI (that is, in the practical use of models such as Chatgpt, which “infers” “their responses from our prompts). They have 288 GB of HBM3E memory and a memory bandwidth of 8 TB/s. Its yield is 18.45 pflops in FP4 precision and 9.2 pflops in precision FP8. Instinct Mi400 in 2026. Next year the new family of AMD’s accelerators will arrive. It’s about future MI400 instinctwhich will arrive with up to 432 GB of HBM4 memory, 19.6 TB/s of bandwidth of that memory, and a performance of 40 pflops in precision FP4 and 20 Pflops in precision FP8. These monsters will be sold in future racks with infrastructure “Helios“, that You can house Up to 72 Mi400 with up to 260 TB/s total bandwidth thanks to its interconnection technology, Ultra Accelerator Link. EPYC VENICE. AMD not only talked about GPUS: it also has its future processors for servers in data centers in full development. The Epyc Venice will arrive in 2026 and will be based on Zen 6 architecture. Among the variants, an especially spectacular with 256 cores that will offer up to 70% more performance compared to the previous generation. These processors will be built with future MI400 instinct. They are expected to be manufactured with the N2P (2 Nm) node of TSMC. Helios against Oberon. The aforementioned Rack Helios will compete with not already with the current Nvidia AI server, the GB200 NVL72 which connects 36 CPUS Grace and 72 Gpus Blackwell. He is destined to compete with his successor, which has Oberon’s code name and will use IA B300 GPUS with Vera Rubin architecture. The yields and benefits of these future racks are absolutely dizzy, and for example their Precision Power FP8 is 1.4 Exaflops. The same in some things, better in others. AMD promises to match NVIDIA in several sections, but also ensures that it will exceed it remarkably (50% more) in memory quantity and width, something crucial for training and inference AI. Be careful, because at the end of 2027 NVIDIA prepares the Rubin Ultra architecture, which promises racks with up to 5 Exaflops in FP8 precision, three times more than Helios or Oberon. In 2027 we will have another “summer”. The AMD roadmap goes further, and they have already prepared the development of their new generation of chips for summer Epyc servers, which will replace the Epyc Venice. These CPUS will be paired with the future MI500X instinct, and it is expected – although it is not safe – that both types of chip take advantage of the one already announced TSMC A16 node (1.6 Nm), which will begin to be used at the end of 2026. There are no specifications for these developments, surely because they will depend on the manufacturing node that AMD ends up using to produce them. Frantic race. All these ads show that AMD does not want to be left behind in that race to place their solutions in data centers worldwide. The Crusoe company, which is dedicated to the construction of large AI data centers, advertisement A few days ago I would spend 400 million dollars in AMD’s chips, and even Sam Altman, CEO of OpenAi, made a surprise appearance During the inaugural talk of the Lisa Su, CEO of AMD event. Altman said they will also use AMD chips in the data centers they use, and highlighted that the new AMD ia gpus “will be somewhat amazing.” AMD presumes to be more efficient (and cheap). AMD’s message was clear during the event: its MI355 offer much more efficiency and are cheaper than NVIDIA B200 and GB200 with comparable yields. The sales prices of those GPUS are not known, but we do know that at the beginning of 2024 the MI300x of AMD They cost a maximum of $ 15,000 for the more than $ 40,000 that cost The NVIDIA H100. The biggest challenge is still CUDA. The benefits of AMD AI chips are not in fact the problem of this company. Detailed studies revealed months ago that MI300X are clearly higher than NVIDIA H100 and H200 on performance and power. However, Nvidia has a Cudathe de facto standard in the industry for services of services and applications of AI. Using AMD native software is feasible, yes, but software experience, They assured in SEMIANALYSIS“Software is full of errors that make training (AI models) with AMD it is impossible.” AMD’s hope is Rocm. In that AMD event also presented Rocm 7, the latest version from your own Open Source programming platform for your GPUS. In AMD they indicated that this version is 3.5 times more powerful than Rocm 6, and even claim that it is 30% more powerful than CUDA in the B200 when serving the model Deepseek R1. Even so, they indicate In another report of semi -health, it is still lower in some sections. Getting that component allows developers to take advantage of all the potential of AMD’s chips is precisely key to the future of those efforts. Even … Read more

The collision between the Milky Way and Andromeda has begun. The good news is that it will not be necessary to fill a friendly part

by

We know that the gaseous extremes of our galaxy and our neighboring galaxy are being touched, but there is no worry. Although astronomers safely a fusion of the Milky Way with Andromeda, they now question it. Short. A astropathic team has just published the biggest portrait of Andromeda, our neighboring galaxy, thanks to the Hubble observations. The image covers 600 fields of vision of the space telescope and shows the entire Andromeda album, which now has more than 200 million censored stars (two orders of magnitude more than those known so far). Although Andromeda’s gas bubbles are already touching the Milky Way, the new data 50% reduce probability that galaxies collide. Gaseous collision. In 2020, the Amiga program mapped 43 quasars in the background, confirming that Andromeda’s plasma halo, a hot gas bubble that measures two million light years, It flasses with the gas halo of the Milky Way. In a way, the gaseous bodies of both galaxies are already being touched, although in a faint way that neither the stars nor the planets notice it, so it will not be necessary to fill a friendly part of an accident. Maybe it never happens. The New 2.5 Gigapixel image of AndromedaResult of the PHAT and PHASET observation campaigns of the Hubble, it is not only another feat of the space telescope. It has served to question the theory that Andromeda and the Milky Way will end up merging. The classical narrative said that both spiral galaxies They would melt in about 4.5 billion yearsforming a giant elliptical. The new model, published in Nature Astronomyreduce the probability of fusion to 50% after 100,000 simulations. How they know. Astronomers at the University of Washington integrated the new Hubble data and the Gaia space telescope of the European space agency in their simulations. In addition to Andromeda and the Milky Way, they included the updated mass of the Great Cloud of Magallanes and m33. The key is in these two satellite galaxies. M33 Andromeda and the probability of shock increases. But the great cloud of Magallanes, with an almost perpendicular orbit, pushes the Milky Way out of the plane and reduces the meeting rate. In the most extreme stage, the front blow is still possible; In the softest, both galaxies will limit themselves to orbly during eons. What we were. The contact of the Andromeda plasma halos and the Milky Way suggests that the exchange of gas between both galaxies has already begun, but that does not guarantee a galactic fusion: the discs are still 2.5 million light years. In order for the merger to occur, the friction of the hals would have to stop the galaxies until the separation is 300,000 light years. Half of the trajectories simulated by the new study discard it. In Xataka | Physics is broken and we have more and more evidence: a new estimate of the Hubble constant delves into the problem
