buying

why understanding these acronyms is the difference between buying an air purifier or an expensive fan

by

At first glance buy a purifier air can be a simple task, but as soon as we start reading the specifications… we can easily get involved, especially with some of them such as the type of filter. Here we must be especially careful because it is possible that we find HEPA filters or HEPA type filters, and they are not the same. In fact, with each of them we will have a totally different experience. How a HEPA filter works HEPA (High Efficiency Particulate Airor air with high efficiency particles) is a quality standard for filters, so if we see it in a purifier we can know that it meets rigorous tests to guarantee efficiency in retaining particles such as dust, pollen, mold and even bacteria or viruses. If we get a little more technical, bacteria measure between 0.5 and 5 microns while viruses measure between 0.02 and 0.3 microns. HEPA filters must be capable of retain at least 99.97% of particles having a size of 0.3 microns (particle size most difficult to physically filter). If it is not capable of this, it is not a HEPA filter. However, you have to be careful because this is where HEPA type filters come into play. What is a HEPA type filter If we see that a purifier has a HEPA type filter, we may think that it meets the standard we have discussed. But this is not the case, and they can be much less efficient. The expression “HEPA type filter” is usually used as a claim for some purifiers, generally inexpensive, although it is more normal to see them in other devices such as robot vacuum cleaner. These filters They are not as effective because they have not been tested with the tests that HEPA filters are subjected to, and it is possible that they do not even comply with the European standard that defines the different kinds of HEPA filters that we can find. Can they retain bacteria? Yes, but they do not have certified efficiency. How purifiers work The purifiers have a fairly simple structure: Inside there is a motor, a fan and a box where the filter is located.. Its operation is summarized in that the motor makes the fan move to attract particles and deposit them in the filter. However, it is worth mentioning that the filtering process is more complex. Inertial impact: affects large, heavy particles that travel at high speed. The particles cannot change direction quickly, so they continue straight until they collide with the fibers until they become stuck. Direct interception: some medium particles that follow the air flow pass very close to the fibers until they come into contact with them and remain adhered, which is known as direct interception. Brownian diffusion: on the contrary, small particles do not follow the air current in a straight line, so they continually collide with the gas molecules in the air. This movement increases the probability that the particle ends up hitting a fiber and becoming stuck. HEPA-type filters can retain certain particles, but they do not have certified efficiency. It’s not that they are useless, but they simply may not be as effective as HEPA filters. The good and the bad of both options, face to face hepa filters hepa type filters THE GOOD 🟢 They are capable of better filtering dust particles, bacteria or viruses. They are usually found in cheap purifiers, being interesting for devices whose purification function is secondary. THE BAD 🔴 They are found in more expensive purifiers, so they are aimed at devices whose purification function is the main one. They are less efficient than HEPA filters. Ideal for: People looking to improve the air quality in their home. Economical devices whose purification function is secondary. What purifier should I buy then? At this point you may have wondered whether or not it is worth buying a purifier with a HEPA type filter, and the truth is that it is, although it depends on what we are looking for. 👉 Choose a purifier with a HEPA filter if: You want to retain large and small particles for a cleaner home, from dust to viruses and bacteria. 👉 Choose a purifier with a HEPA type filter if: You only want to retain large particles such as pet hair, dust or lint. Recommended models Philips 2200 Series He Philips 2200 Series It is an air purifier with a HEPA filter that has a fairly small format. It incorporates a three-layer system composed of a prefilter, a HEPA NanoProtect and active carbon to capture 99.97% of particles up to 0.003 microns (3 nanometers) through NanoProtect technology, a technology that allows even smaller particles to be captured thanks to electrocharging.

We thought that buying a yacht was a luxury. The real luxury that they don’t tell you is another: maintaining it

by

Owning a yacht is synonymous with luxury and opulence. It is not for less. Superyachts like the koru by Jeff Bezos or the Leviathan by Gabe Newell, they had a purchase price of 500 million dollars; he launchpad by Mark Zuckerberg about 300 million dollars. However, although buying a yacht seems the most difficultwho has been in the sector for some time knows that this initial disbursement will not be the only one, it is only the first. The true luxury (and what is really expensive) is what comes after and is repeated every year: the maintenance of that yacht. There is an unwritten rule that has been circulating around moorings and ports for decades to prepare future buyers for what awaits them. It is called the “10% rule“, and refers to the annual maintenance cost that a yacht requires: 10% of its price, each year. The inhabitants of the Caribbean island of Antigua they learned it the hard way. The price of a yacht does not come on the label When someone is going to buy a boat, it is usual to take into account whether they can afford its purchase price. That’s the easy part. You look at the price and compare it to your checking account. If it fits the budget, honey on flakes. However, there is a cost that not always taken into account in which the owner of a yacht (or any boat in general) should reserve approximately the 10% of the purchase price to cover all expenses annual operation and maintenance. Yes, 10% of the price each year. A 500,000 euro yacht will generate annual costs of around 50,000 euros; If the value amounts to one million euros, the figure rises to 100,000 euros per year. That 10% includes practically everything necessary to keep the boat sailing and in perfect condition: routine maintenance, regular repairs, average fuelannual insurance, mooring fees and, in the case of larger superyachts, crew salaries. Boat insurance alone already represents between 1.5% and 2% of the value of the yacht per year, which in a 500,000 euro boat translates into between 7,500 and 10,000 euros per year in premiums alone. At this point, it should be noted that these premiums are also calculated based on the location of the mooring. A yacht moored in the Mediterranean does not pay the same insurance as in areas like Florida where hurricane warnings and tropical storms are the order of the day. As the ship ages, the numbers change The 10% rule is stated as a reference guide for the entire life of the yacht. That is, it is an average in which some years the maintenance cost will be well below that 10%, while in other years it will far exceed it. However, above or below, the cost always remains close to that 10%: As and as they point out from WS Yatch Brokersone of the decisive factors, for example, is that this 10% varies as the age of the boat advances. When the yacht is new, the manufacturer’s warranties are in force, the mechanical systems are working well and maintenance costs can remain around 2% of the purchase price for the first few years. That 2% corresponds to fixed expenses such as insurance, mooring, or basic deck maintenance. As the years go by, parts wear out, warranties expire, and breakdowns become more and more frequent. For boats between 5 and 15 years old, the recommended percentage rises to 10%, with bad years that can reach (and exceed) 15% of the purchase value. The reason is that, as the market value of the boat goes down, its maintenance costs go up, so any calculation based on a fixed percentage loses reliability. That is to say, a 15-year-old yacht that has cost 100,000 euros second-hand will not (or at least not always) have expenses of 10% since its engine and hull begin to need major repairs due to years of use. That is, what the buyer has saved on the purchase price must then be invested in repairs anyway. Hence the 10% rule is a reference average applied to the entire life of the yacht (with its ups and downs), not a rule written in stone. The size, the crew and the place where you moor Size also determines the maintenance budget proportionally. From 25 meters in length, the yacht can now require professional crewand that 10% falls short to cover the cost of maintenance. A captain’s salary alone starts at around $50,000 per year, and a full crew for a large yacht easily exceeds $200,000 per year. On megayachts, managers usually plan 10% for operating expenses (which are included in the 10% rule), plus an additional 10% for onboard personnel, their maintenance, etc., which places the real maintenance cost closer to 20% of the acquisition price. This percentage does not apply to those yachts that, due to size, only require the services of a captain during the high season, thus reducing their annual cost. He port where it is moored It also has a decisive influence on the calculation of annual fixed expenses. It does not cost the same to moor in a small fishing town on the Catalan coast as in Puerto Banús or in the port of Monaco. In Spain, the monthly mooring fee for a boat between 12 and 14 meters ranges between 450 and 575 euros per month (about 6,900 euros per year), but it skyrockets in large tourist ports. to put a practical examplemooring in Marina Ibiza, the main recreational port on the island, for a yacht of about 15 meters in length costs between 25,000 and 30,000 euros per year, while if you opt for other secondary ports on the island, the price is reduced by half to between 10,000 and 15,000 euros per year. According to estimates of Ocean Independencea company specializing in superyacht management, the annual routine maintenance of a superyacht, which includes hull cleaning, fuel, engine inspection and electronic systems, ranges between … Read more

Andalusia has been buying and burying garbage from the rest of Europe for decades. And now he has said “enough”

by

Four years ago, 40,000 tons of contaminated soil and stones were blocked at the doors of the Nerva landfill in Huelva. They came from Montenegro and no, it is not an isolated event. During the last 25 years, Andalusia has been a massive recipient of hazardous waste. More than 100,000 tons traveled kilometers and kilometers each year to be buried south of Sierra Morena. That just ended. It’s good news and a huge problem. What has happened? On April 26, 2026, the last authorizations that still allowed companies from outside Andalusia to discharge hazardous waste into Andalusian landfills expired. Three years after the approval of the Andalusian Circular Economy Lawthe restriction on sending hazardous waste whose final destination is the landfill is now complete. It is not an absolute moratorium, of course. The entry of dangerous substances is still allowed for ‘recovery’: if waste from outside is recycled, regenerated or thermally treated on Andalusian soil, it can continue to be introduced into the community. That, according to the Association of Waste and Special Resources Management Companieshas left more than 100,000 annual tons of hazardous waste in the air that until April had been managed (‘burying’) in Andalusia. Hence the problem. Because hazardous waste landfills are rare and very expensive infrastructures; as they explained in Civio“any reordering of flows has an immediate impact on the economic viability of the plants.” These months are critical for the industry. However, the Andalusian movement is not well understood without some context: the Andalusian decision begins in the same place as this article, in Nerva. What exactly is Nerva? He Andalusia Environmental Complex, in the Río Tinto basin, has operated since 1995 and for decades it has received hazardous waste from the Huelva Chemical Pole, Campo de Gibraltar, the rest of Spain and abroad. It is, as a consequence of this and before this, a dangerous place. In Huelva, the main public health problems they associate to prolonged exposure to heavy metals and toxic compounds derived from decades of industrial activity (and from storing hazardous waste from other places). In fact, the two main focuses are the phosphogypsum ponds (about 500 meters from the city) and the Nerva landfill. I have to correct myself: they are not associated with that. Technically yes, health wise yes: but, in reality, the main public health problems are associated with the negligence of administrations, the lack of management and the recklessness that comes with just worrying about money. The Andalusian ban was necessary. Because, despite the legal tension (the fact of facing community law), at some point the administration had to assume its own responsibilities. This does not solve Nerva’s problem, as is evident. But it forces the industry to take charge of everything that has been going on for years without anyone watching.

Anthropic is one step away from being worth as much as Samsung. And what the market is buying is not Claude

by

Anthropic, the company behind Claude, is exploring a new round of financing that would value it at more than 900,000 million dollars. If it closes, it would surpass OpenAI as the world’s most valuable AI startup. Altman’s company set its needle at 862 million last month. The figure more than doubles the 350,000 million it had in February. In just two months. Why is it important. The valuation no longer reflects Anthropic’s sales. It responds to a bet on what the company can become in five years or a decade: a provider of something resembling an essential service. Anthropic bills Claude for subscriptions and accesses to its API. That business exists, grows quickly and has reasonable margins. But it does not by itself justify a valuation that is close to that of Samsung, the Korean megalodon that manufactures everything from the chips we carry in our pockets to the ships that cross the ocean. The context. What the market is buying with Anthropic, and as often happens in the stock market, is not the present, but a hypothesis: that a very small handful of laboratories will control the foundational layer on which the software of the next decade will be built. And that Anthropic will be one of those few. And it will do so in a very profitable way. The logic, on the other hand, is the same that led to overvaluing telecos during the bubble dotcom or to the electric companies at the beginning of electrification. Whoever owns the basic infrastructure sets the rules. Google has already committed 10 billion to the previous valuation, with another 30 billion conditional on objectives. Amazon has put in 5 billion and plans to inject 20,000 more. An IPO could come before the end of the year, around October. Between the lines. That Google and Amazon, two of the largest cloud companies in the world along with Microsoft, finance a company that also sells through them says a lot about how they understand the moment. They are ensuring supply, it is not just an investment in a supplier. It is the difference between buying shares in an oil company and buying a field. Anthropic is, for these hyperscalersa deposit. Yes, but. The hypothesis has its cracks. The models are commoditizing faster than it seemed a year ago. The technical difference between Claude, ChatGPT and Gemini It is measured in nuances, not in generational leaps. If foundational AI ends up being a commodity (something like electricity or water coming out of the tap), current valuations are unsustainable. If it ends up being an infrastructure with network effects and high barriers to entry (something like an operating system), they may even fall short. The market is paying for the second hypothesis. Time will tell. The money trail. Anthropic recently announced, with restrained fanfare, Mythosa model capable of detecting and exploiting vulnerabilities in critical software. The company deemed it “too dangerous” to release and has only given it to a closed group of companies for internal testing. Even so, it has been accessed by unauthorized users. That is exactly the reason why some investors pay these figures: such a model is not sold but granted. And whoever decides to whom it is granted has regulatory power de facto that not even a Samsung, at least outside of South Korea, has ever had. The big question. What happens if the bet goes wrong? A valuation of 900 billion means that Anthropic has to generate, at some reasonable point, revenues in the order of tens of billions a year with very high margins. It is possible. But it was also important for Cisco to maintain its 2000 valuation, and it has needed 26 years to tie. The difference is that this time the buyers of the bet are the companies themselves that depend on the result. This reduces the risk of a sharp correction. And he postpones it.

buying Globalstar’s “candy” for $9 billion

by

SpaceX has been positioned as a the great giant of telecommunications satellites thanks to Starlink. However, other seemingly more modest companies have been able to occupy the space left free by their weak points. One of them is Globalstar. For this reason, Amazon has set itself the goal of acquiring it as soon as possible. The facts. According to CNA and ReutersAmazon is currently in negotiations to acquire Globalstar for 9 billion dollars. The final transaction could be announced this week, although at the moment nothing is finalized. It would be a big step forward for the e-commerce company when it comes to telecommunications, but to achieve it will also have to reach an agreement with Apple. Starlink vs Globalstar. Starlink currently has more than 10,000 satellites in orbit. SpaceX’s plan is to initially scale up to 12,000 satellites and, if possible, in the future to exceed 40,000. With this, it is intended that Internet access will be broader and faster, by directly connecting users with satellites located in geostationary orbit, without the need to use ground stations as intermediaries. Globalstar has a similar goalalthough it has many fewer satellites. Just a few dozen. However, Globalstar has something that Starlink craves: licensed spectrum. The VIP area of ​​telecommunications. A licensed band in the radio spectrum is a specific range of frequencies that has been assigned by the competent authorities to a specific operator. For the duration of the license, only that company can transmit in that range. This means that interference is reduced to a minimum. There are no other satellites competing to send their signals. Apple enters the scene. Globalstar’s licensed spectrum is a candy highly desired by any telecommunications company. One of them, without a doubt, was Apple. In 2024, the telephone giant invested $1.5 billion in Globalstar, acquiring 20% ​​of the company. Since then they have used it, for example, to send emergency messages or to use offline maps. Given this situation, Amazon will have to negotiate directly with Apple and reach an agreement. More satellites, but worse positioned. Actually, Amazon already has its own satellite project, called Leo. It currently has 200 satellites in low orbit and many more ready to launch when the necessary permits are obtained. However, many of these permits do not arriveso Amazon has been experiencing delays in its release schedules. This has led the company to make the decision to join forces with Globalstar, as it has a much smaller train of satellites, but clearly better positioned thanks to the licensed band. If they reach an agreement, they will be able to start working at full capacity much sooner. Starlink is not going down. Despite the virtues of Globalstar and the forces it could combine with Leo, Starlink is not positioned as a losing company. The power that having the largest train of telecommunications satellites gives it is still very great. However, the space is becoming saturated and there are more and more entities concerned about what the growth of this company could entail. If your maneuver based on the brute forceperhaps there could come a time when you find yourself at a disadvantage. We will have to wait to see it.

American refrigerator or 70 cm Combi? Be careful with making mistakes when buying liters that you may not be able to use

by

I don’t know about you, but when I go to the grocery store, it often feels like I’m preparing for a catastrophe. Many of us live at home and I don’t like going shopping every other day, so I try to put in the cart what I need for at least a week. What’s happening? Then you need space at home to store it.. I have plenty of cabinets and drawers, but my kitchen refrigerator doesn’t have as much space as I would like. Even though I don’t have a kitchenettethis whole situation has made me consider more than once about jumping into an American refrigerator (you know, the ones with two doors with a left-right distribution). But, Is it really worth it compared to a wide combi? Let’s see which one can fit best in your kitchen and your needs. Bespoke AI American Refrigerator 178cm 659L Class E Inox RS70F65QETEF The price could vary. We earn commission from these links Choosing an American refrigerator If you start browsing stores looking for an American refrigerator, you will see that they all have a very large capacity measured in liters. This is something that cannot take us by surprise, although it has a certain “trick”, since it adds the space of the refrigerator to the freezer. What not many people notice is that, although these refrigerators are very large, the reality is that they are also narrow. And that’s where it comes in the pizza box test. There’s not much science to it, it’s just what you think: since the shelves are narrower, a pizza box does not fit horizontally. This is the most visual example, but you can take it to other everyday things that you are more likely to keep in your refrigerator. There we can include food trays, cakes, large tupperware or even watermelons if they are large. Now, what you lose in width you gain in height. This is ideal if you are one of those who practices batch cooking and you cook in one sitting for several days, so you can stack the tupperware without any problem. In addition, you can also take advantage of the more vertical distribution of the refrigerator to your advantage, placing the things you use most at the top and the things you use least at the bottom. More things to keep in mind about these refrigerators. First, the best thing they have: the freezer. The left-right distribution means that we have plenty of room to freeze things of all kinds and have them very well organized. Not only that, but its more vertical distribution also means that we can have a lot of space at eye level and not have to bend down every time we want to check what we have frozen. All this has a price (and never better said), since American refrigerators have higher energy consumption. There is also the issue of the water and/or ice dispenser that these types of refrigerators normally come with. It depends on the model, but there are those that need a water intake to make this workalthough there are others that have a tank that we can fill without the need for installation. And, speaking of installation, be careful with American refrigerators: they are deeper. This can make them stand out from the line of the furniture, something that aesthetically does not look very good. Choose a wide combi The vast majority of vans in stores are about 60 centimeters wide. We would not put one of these to compete in capacity with an American, but things change if we add 10 centimeters to the formula. It seems like very little difference, but from 70 centimeters wide, the combi gains a lot more capacity. And, of course, without taking up as much space in the kitchen as an American refrigerator. These pass the pizza box test without breaking a sweat, since its shelves are much wider. Now, the extra total capacity they gain is not enough to beat the American refrigerators. Not through the refrigerator, but through the freezer. There they clearly lose out, so if you have a freezer full of food, it may not be worth it to go for a combi. There is also the issue of consumption. It will depend a lot on the model we choose, but as a general rule, one of these wide combis It will consume less energy than an American refrigerator. It will not be a consumption figure large enough for us to rule out the Americans, but it will be something to take into account. The good and the bad of both options, face to face American refrigerator wide combi THE GOOD 🟢 Plenty of space to freeze and stack tupperware in the fridge You can have frozen products at eye level so you don’t have to bend down all the time Much more horizontal capacity for large containers and takes up less space Less electricity consumption THE BAD 🔴 Uses more light and has less horizontal space to store large things The “aisles” of the refrigerator are narrow, so if you put something bulky you won’t see what’s behind it Your freezer doesn’t do much, so you may have to juggle if you freeze a lot of food. Ideal for: Kitchens with a lot of space and for large families who need a huge freezer Smaller kitchens and for storing very wide trays or containers without a problem In summary: 👉 Choose an American refrigerator if: You have plenty of space and if you prioritize maximum capacity in your freezer. 👉 Choose a wide van Yeah: You prefer to have wide shelves and you want a large refrigerator, but not gigantic. Recommended models American refrigerator: Bespoke AI RS70F65QETEF As an American refrigerator option, we have this one from Samsung.

buying it will cost 100 euros more in Europe very soon

by

That one is very far away PlayStation 5 launch price that many of us had in our heads when this generation began. We are talking about the end of 2020, when the console arrived in stores for 499.99 euros in its version with a disc reader and 399.99 euros in the digital edition. Since then, several things have happened that have marked its trajectory, but there is one that is especially striking: instead of becoming cheaper with the passage of time, something more common in mature generations, Getting a PS5 has been becoming more and more expensive. That journey takes us directly to the announcement that Sony has made todayMarch 27, 2026, in which it confirms a new price increase for its consoles in Europe with effect from April 2. The company recognizes that this is a sensitive decision for users, but frames it in a context of “continued pressures in the global economic landscape.” According to Isabelle Tomatis, vice president of global marketing at Sony Interactive Entertainment, after evaluating the situation they have concluded that this adjustment is “necessary.” A generation that has become more expensive With that announcement already on the table, what really interests us is how much it now costs to enter the Sony ecosystem in Europe. As we say, to starting April 2, 2026these are the recommended prices that the company has set for its consoles in this market: PS5: 649.99 euros. PS5 Digital Edition: 599.99 euros. PS5 Pro: 899.99 euros. To fully understand the current moment, it is worth looking back and seeing that this is not the first time that Sony has revised the price of its console upwards in Europe. The first movement arrived in August 2022, when the PS5 with reader went up up to 549.99 euros and the digital version up to 449.99 euros. Another adjustment was added to this adjustment in April 2025, focused on the Digital Edition, which reached 499.99 euros. What we see now, therefore, is not an isolated case, but another episode within a trajectory of upward prices that has been consolidated over time. In this scenario there is an important nuance that should not be lost sight of: the PS5 Pro He plays in another league within this story. The console was launched in Spain in November 2024 with a recommended price of 799.99 euros in its 2 TB version without a disc reader, and until now it had not undergone adjustments. The increase announced now places it at 899.99 euros in Europe, which represents its first increase since the launch. If we put all the pieces together, what remains is an unusual photograph for a console that has been on the market for several years. Far from getting cheaper over time, the PS5 has been chaining reviews of rising price around the worldincluding the one now announced by Sony. This pattern, conditioned by economic factors that the company mentions in its statement, changes the rules for the consumer. Today, getting a PS5 is more expensive than ever.

that buying a yacht is as cheap as a car

by

The man who turned JD.com into the Amazon’s biggest Chinese rivalhas just announced his next project. This time it’s not about packages or deliveries in 24 hours: this time it’s about yachts. Yes, those luxury boats that until now only the richest could afford among the rich. However, his plan is not make yachts for millionaires. That can do any. The challenge is to manufacture yachts that any minimally wealthy family can afford. Their goal is to manufacture yachts at the same price as a car. The “Chinese Jeff Bezos.” Richard Liu is popularly known as the “Chinese Jeff Bezos” for having converted your company JD.com into an online commerce giant with its own logistics capable of overshadowing the almighty Amazon. According to ForbesLiu has an estimated net worth of around $5.5 billion, placing her as one of the China’s biggest fortunes. Liu wants to replicate that philosophy of scale and efficiency that he has honed at JD.com in a completely different sector: boat manufacturing. For this purpose, Sea Expandary has been created. a new company which will not be managed directly by him since he will have his own independent CEO. The planned initial investment is around 5 billion yuan (about $723 million), and the goal is so ambitious that it is hard to believe: that any salaried worker can have his own yacht, just as happened with the car decades ago. Price is what changes the rules of the game. The most striking fact of the proposal is the target price for the boats they manufacture. As I collected Asian outlet SCMP, Liu has stated that: “I hope that one day we can build yachts priced at 100,000 yuan (US$14,502), so that they can enter homes like cars do. Yachts must be difficult for ordinary wage workers and ordinary consumers.” To put that figure in context, according to boat insurance portal Admiral Marine, a small entry-level yacht can easily cost between $50,000 and $200,000. The ambition is that this boat will have enough space on board for a family and that its price will not be an obstacle for Chinese households to buy one. Making boats is complex. Building ships is not an easy task. The nautical sector continues to be one of the most artisanal and labor-intensive, with long production cycles and greater flexibility must be applied in the customization of finishes and uses. To reach that price, Sea Expandary would have to radically industrialize the process, limit the variants it offers to its customers and optimize the supply chain. Furthermore, the new company not only aims to be cheap, but also sustainable. Liu has announced that all Sea Expandary yachts will operate with what he has called new energy technologies that focus on the electrification of engines and renewable energy generation systems. This is a positioning that fits well with the industrial policies that China has been promoting in the renewable energy sector that is already is applying in cars. It’s a good business. The yacht market in China is in full boiling. According to the market outlook By the end of 2025 there were 9,850 vessels registered in the country, and more than half of the total fleet had been registered in the last three years. The Chinese Ministry of Transport said that growth is expected to continue over the next five years. The global yacht market, for its part, exceeded $9.83 billion in 2025 and is expected to reach $14.98 billion in 2035, with compound annual growth of more than 4.3%. China is late to this sector compared to Europe or the US. However, China arrives with a more than proven competitive advantage: its industrial-scale production capacity, lower manufacturing costs and the support of public policies. Liu knows this, and he said it bluntly: “Only by doing this can we truly compete with the world’s leading yacht manufacturers in Europe and the United States.” In Xataka | The ultra-rich trade land for a superyacht during the summer: These are some of these floating mansions Image | Flickr (Fortune Brainstorm Tech 2018), Pershing

For years, Meta has relied almost entirely on NVIDIA and AMD to power its data centers. The development of our own silicon is complicated, but if it is achieved, it can be a very successful financial and strategic bet in these times. According to statements According to its vice president of engineering, Yee Jiun Song, designing its own chips allows the company to “eliminate what we don’t need,” which directly translates into cost reduction. Added to this is greater independence from possible price variations or supply restrictions. Which is exactly what you have announced. The four new chips are the MTIA 300, 400, 450 and 500. Each one has a different use: The MTIA 300 is already in production and is intended to train the algorithms that decide what content Facebook and Instagram users see. The MTIA 400 (known internally as Iris) has completed laboratory testing and is en route to data centers. Meta claims that it offers performance “competitive with leading commercial products,” according to its official statement. The MTIA 450 (Arke) will double the high-bandwidth memory compared to the 400 and is scheduled for early 2027. The MTIA 500 (Astrid), the most advanced, will arrive in mid-2027 and will incorporate, according to the company, improvements in low-precision data processing. The chips are manufactured by TSMC, the world’s largest semiconductor producer, and have been developed in collaboration with Broadcom on the RISC-V open architecture. The rhythm is the most striking thing. What’s unusual is not just that Meta makes its own chips, but the speed at which it plans to do so. The usual cycle in the industry is one or two years between generations. Meta aims to release new versions every six months. “The pace of AI evolution is so fast that we always want to have the most advanced chip available when we need it,” counted Song. This accelerated cadence is possible, according to the company, thanks to a modular design that allows components to be reused between generations. ANDthis does not replace NVIDIA. It is important not to lose sight of the context. Meta remains one of the largest buyers of GPUs on the market. just a few weeks ago signed multi-million dollar agreements with NVIDIA and AMD to supply chips for the next few years, and has also reached an agreement to rent computing capacity on Google chips, as share Wired. MTIA chips are designed for specific and internal tasks (inference and recommendation systems), not for training large language models, so this strategy is complementary to your chip plans with NVIDIA or AMD. Nor should we forget that Meta recently had to abandon its most ambitious training chip, known internally as Olympus, after the project became complicated in the design phase, according to counted The Information. Susan Li, CFO of Meta, confirmed at a Morgan Stanley event that the company still has the goal of developing processors capable of training models, but without giving more details. And now what. The real test of this bet will come when the chips are deployed at scale. The challenge at the moment is to guarantee HBM memory supply before a RAM crisis that is affecting the entire technology sector. Song himself recognized to CNBC that the company “is absolutely concerned” about it, although it stated that they have assured supply for their current plans. In the long term, we will see if Meta can achieve something similar to what Google did with its TPUs.

Why does your refrigerator dry out food and when is it worth buying a ‘low frost’ one?

by

Nowadays most refrigerators are “No Frost”, but… what does this really mean? Perhaps what you have heard the most is that they do not make frost, but they also have other peculiarities with respect to the more traditional models. For this same reason, today we are going to review the differences between both types of refrigeratorswith the advantages and disadvantages in each case. How a No Frost refrigerator works No Frost refrigerators use fans that constantly remove the coldwhich prevents water vapor from condensing on its walls. Since there is a constant, dry air flow, moisture does not accumulate in the form of ice, which prevents us from having to remove it ourselves. In addition, many models have a system that allows you to eliminate small traces of ice if they appear. This No Frost system has some especially interesting advantages beyond not forming frost. By having a constant air flow, this cold air reaches all corners of the refrigerator equally, homogeneously, which allows all foods to be preserved better for longer. Now, it’s not all advantages. When using a No Frost refrigerator, it is advisable that we take into account that your air system is dryand by reaching all corners evenly it can dry out food, especially fresh items such as fruit, sausages or vegetables. We must also pay special attention to another point: No Frost refrigerators consume a little more because they have a resistance that heats up to melt the ice automatically. For this reason, we recommend looking at the annual consumption in kWh, and not only at the letter of energy efficiency. How a cycle refrigerator works Cyclic refrigerators (also called Low Frost either Less Frost by some brands) are the traditional ones, the traditional ones. They work through a refrigerant gas that travels throughout its circuit until it reaches the desired temperature, at which point the air flow stops. It does not work using fans, so they can generate less noise than No Frost. As the cold of these refrigerators is humid and they do not have a fan that constantly stirs the air, plaques of frost can form on the walls, which forces us to remove them manually so as not to compromise their efficiency and durability. Additionally, if too much frost forms, the refrigerator motor may have to work harder, which means possible increase in electricity bill. The good thing about these refrigerators is that by having a system that generates humid cold, food is usually better hydrated, preserving it better for longer. This occurs especially in fresh foods such as vegetables, which hold up better without drying out. The good of both worlds We can also find refrigerators that bring together the best of both worlds: hybrid refrigerators. In this case, they come with both systems, but separate: the No Frost system in the freezer and the cyclic system in the refrigerator. This prevents frost from forming in the freezer and allows the fresh food in the refrigerator to stay moist for longer. In other words: mixed models come with a No Frost freezer which prevents us from having to chip away at the ice that forms every so often and they also have a cyclical or dynamic refrigerator that prevent fresh foods, such as lettuce, from drying out. The good and the bad of both options, face to face No Frost Cyclic (traditional) THE GOOD 🟢 You do not need to remove the ice manually, the temperature is more homogeneous on all shelves and the food tends to cool faster thanks to the fan air system. They keep food fresh for longer and are usually quieter and cheaper. THE BAD 🔴 Their dry air can dry out fresh foods and they tend to be noisier due to the operation of the fan. Plus, they tend to be more expensive. They can form frost on your walls and can cause uneven temperatures on different shelves. Ideal for: Storing a lot of food in the freezer without the ice blocking the drawers or for families that open and close the freezer constantly, thus recovering the optimal temperature in a short time. Eat a lot of fruits or vegetables without losing moisture in a short time or if you want a refrigerator that makes little noise. We do the math to see which one can compensate you more. Each of the refrigerators has its advantages or disadvantages, so to see everything much clearer we are going to give a couple of practical examples. If you are looking for a refrigerator that allows you to use it without further ado, without worrying about removing frost every few months, a refrigerator with a No Frost system will compensate you much more. Actual use: Let’s say you usually freeze a lot of food. The accounts: No Frost refrigerators allow you to better recover the temperature by opening and closing the freezer many times. In addition, you avoid emptying it to defrost the ice every few months. So? It is a choice that lies in both the comfort and the usefulness of the freezer: fresh foods dry out more, but in exchange we have a freezer that better maintains its ideal temperature. If you opt for these refrigerators, at least have one or more drawers with humidity control, generally called VitaFresh or BioFresh. Although there are fewer of them in stores today, refrigerators that are cycled or have a traditional system can be very attractive, both for the preservation of certain foods and for other characteristics. Actual use: You don’t usually freeze a lot of food and you usually eat a lot of it fresh. The accounts: Having a cycle refrigerator allows fresh food to last better. In addition, by not using a fan constantly, they tend to make less noise. So? It is ideal if you consume more fresh foods than frozen foods or if you have the refrigerator next to, for example, the living room and you are looking for as little noise as possible. … Read more
