The Raspberry Pi 5 are so expensive that buying two with 16 GB of RAM costs the same as a MacBook Neo

by

If today you decide to buy a Raspberry Pi 5 with 16 GB of RAM, we have bad news: its price in the Adafruit store is 350 dollars. In Spanish stores like Raspipc.es the price with VAT is 313.03 euros. It is an absolutely absurd price for a miniPC with these characteristics, but the memory crisis has made us live in a world of crazy prices and absolutely strange situations. For example, what we propose here: For the price of two Raspberry Pi 5 with 16 GB of RAM you can buy a MacBook Neo. Or almost. In Spain, the price of the MacBook Neo is 699 euros. In the US it is $599 without taxes, so that comparison certainly holds true there, because although it depends on the state in which you buy it, the final price is around $650. Less than two of those Adafruit Raspberry Pi 5s cost. What is happening is amazing but very real: Raspberry Pi 5 are really striking miniPCs that anyone can use even as a desktop PC and offer surprising possibilities. But in the comparison with the MacBook Neo (or even with 700 euro Windows laptops) they lose by a landslide. And in the MacBook Neo we have a much more “rounded” laptop as a product for the vast majority of users. Not only because it has a laptop with an enviable construction with its screen, keyboard and trackpad. It is true that the unified memory is 8 GB (the RPi 5 with 8 GB costs $200), but we are looking at a much more capable computer in terms of performance. Source: GeekBench. In GeekBench 6 the 16 GB RPi 5 gets 899 points in single-core and 2,144 points in multi-core. The Apple A18 Pro from the MacBook Neo gets 3,566 points in single-core and 8,646 in multi-core: It is four times more powerful in this synthetic benchmark. It’s all a reality check. What happened to the $25 computer promise? Just two months ago Eben Upton, creator of the Raspberry Pi, announced the launch of a new Raspberry Pi 4 with 3 GB of RAM. Under other circumstances this launch would have been strange, especially considering that the Raspberry Pi 5 is available for almost two years and the original Raspberry Pi 4 were launched, attention, in 2019. Pre-pandemic. That announcement, however, made a lot of sense because the memory crisis has caused the prices of all types of devices to increase extraordinary. Upton himself revealed that the price of the LPDDR4 RAM memory modules used in the Raspberry Pi 4 and 5 had multiplied by seven. Hence the launch of an “affordable” version that at the time had a price tag of $83.75. The rest of the Raspberry Pi models, however, were impacted by the memory crisis and the creator of these devices announced significant price increases for all of them. Everything has meant that the company has had to betray its original objective more than ever. That $25 computer that was going to conquer the world soon made it clear that it was going to do so, but with many sacrifices: its original performance was poor, and you actually had to spend more money to use it with a monitor, mouse and keyboard (in addition to the SD/microSD, the necessary cables and the power adapter). Over time we saw how the Raspberry Pi became a much more rounded and capable product both in its original version and in others such as the fantastic RPi 400/500. But in doing so inevitably the price also increased: in November 2022 we complained about the lack of stock and that its price It was no longer 35 euros like the original, but triple. The firm, however, has always tried to maintain that spirit with which it was born, and in August 2024 it launched its Raspberry Pi 5 with 2 GB for $50. Today this model can be found at about 70 euros in Spanish stores, but of course, those 2 GB are not enough for that price. The memory crisis has harmed the entire market, but it has hit especially hard with these small miniPCs. The Raspberry Pi cannot compete in price/performance with more complete devices, but They continue and will continue to be a fantastic alternative in educational environments and, of course, in the industrial field in which the RPi in its Compute Module format have managed to become in all a reference.

FIFA has turned the 2026 World Cup into the most expensive cultural event in history because it has become a new Ticketmaster

by

For almost a century, FIFA has not cared about selling cheap tickets: the money in football was in television. But as has happened with the musiccinema and other cultural events, spectacularization is the order of the day, and for the 2026 World Cup the business model is closer to Ticketmaster. Direct consequence: two US attorneys general have already asked him for explanations through judicial means. Pocho record. The World Cup in the United States, Mexico and Canada starts this Thursday, becoming the most expensive cultural event in history. The cheapest ticket to the group stage cost an average of $200 and the most affordable ticket to the final started at $2,030. Adjusted for inflation, the price is double that of Qatar 2022 and quadruple that of the United States 1994. Because. The reason is more than obvious: for the first time, FIFA controls ticket sales directly, without delegating it to local organizers, and has launched dynamic prices. Between October and April made at least one category more expensive in 95 of the 104 gameswith an average increase of 35%. The Category 1 ticket for the final went from $6,730 to $10,990. Other niceties. Another novelty this year that is not going down well with fans is that the buyer does not choose a seat either. You pay for a category that corresponds to an area of ​​the stadium and FIFA assigns you a row and seat months later. For example, in April many fans who had paid for Category 1 discovered that their seats were in areas previously marked as Category 2, because FIFA had modified the maps and reserved the best seats for a new “Front Category 1”. More expensive, of course. The law. The attorneys general of New York and New Jersey have judicially summoned to FIFA to investigate your sales practices; The one in New Jersey accuses the agency of turning the purchase into a labyrinth of “false scarcity.” California had previously sent its own letter of request. Justice accuses FIFA of setting up its own secondary market without price caps in the United States and Canada: as explained your own support pagecharges a commission of 15% to the seller and another 15% to the buyer. Only in Mexico does it limit resale to the original price, and by legal requirement. On that platform there have been tickets for the final listed by more than two million dollars. The opacity does the rest. FIFA has almost never reported how many tickets were left per match or per phase, and before publishing any price it sold tens of thousands of “Right to Buy” tokens through its crypto collectibles platform: hundreds of dollars for the right to buy a ticket whose final cost was not known until much later. More opacity: in February, FIFA president Gianni Infantino stated that all matches were sold out. His own organization had to correct himand in April acknowledged that about five of the planned 6.7 million tickets had been sold and that the rest were being held for “continued sales.” Different ticketing experts identify this retention as a classic tactic to create a sensation of demand. Although it is not clear if the play has given the expected results: the United States’ debut against Paraguay accumulated 10,000 entries listed on resale platformsa, many below the original price. The accounts come out. Wow, they come out: in Qatar 2022 the box office contributed about 950 million dollars; for 2026 FIFA budget up to 3,000 million for tickets and VIP packages (premium entry plus experience). The organization foresees earn 8.9 billion with the tournament within a four-year cycle of 13,000 (which is how FIFA organizes its accounts) in the most optimistic calculations. There are those who consider that this calculation even falls short: an academic analysis It projects that the box office and VIP experiences alone will exceed 7.4 billion, and to that would be added TV rights, sponsorships and other income. One but. The Economist It points, however, to a very specific problem this year: the public in the fields is part of the television product that FIFA sells around the world for more than 4 billion dollars. It must be remembered that in the Club World Cup, spectators had to be relocated in front of the cameras in half-empty matches to keep up appearances. All of this underlines the idea that FIFA is torn between a couple of businesses in which it wants to be the leader: squeezing in-person spectators and protecting the image of the spectacle that the rest of the planet sees. For now the eyes with the dollar sign are watching intently at the first one. In Xataka | How to configure your Smart TV to watch the 2026 World Cup in the best possible way

Claude Fable 5 is the most powerful public AI model in history. Also the most expensive, exclusive and frustrating

by

When Anthropic presented Claude Mythos Preview two months ago, he did it with a singular message: it is so powerful that you will not be able to use it. That, of course, caused everyone to want access to it. Well: Anthropic has just introduce Claude Fable 5 and Claude Mythos 5its new AI models directly derived from that. There is good news, but also bad news. Like Mythos, but capped as a precaution. Anthropic already warned that Claude Mythos Preview was a spectacular tool for finding security vulnerabilities. That made it especially juicy for cybercriminals, so the company decided that only a few trusted entities (under its Project Glasswing) would have access to the model. That learning has now been applied, because in this announcement we have two different (and layered) versions of the model: Claude Fable 5: a model with all the capabilities of Mythos Preview, but with notable security measures that prevent it from being used for malicious purposes. As soon as the model detects that we are asking something “dangerous”, it avoids the question and even forces the use of an inferior model, Claude Opus 4.8. Clear examples: questions about cybersecurity or the development of biological weapons, for example. Claude Mythos 5: This version is somewhat less capable than Fable 5 in terms of cybersecurity, but will only be available to “a small group of cyber defenders and infrastructure providers.” It is the natural heir to Mythos Preview, and according to its creators it is even better than the original version. Claude Fable 5 / Mythos 5 simply sweeps the most demanding benchmarks on the planet. There have never been more powerful models. Anthropic’s internal testing shows that we are facing the most powerful AI models in history. In all benchmarks – including the new FrontierCode programming, much more demanding than SWE Bench Pro – the scores of Claude Fable 5 and Mythos 5 are simply spectacular, well above those of their rivals. The jump from Claude Opus 4.8 is really surprising, but it leaves GPT-5.5 and Gemini 3.1 Pro far behind (they don’t compare with the recent 3.5 Flash). This is a brutal blow to Anthropic’s table, and we will see how both OpenAI and Google respond. Claude Fable 5 is amazing. Ethan Mollick, well-known AI popularizer, has had access to Fable 5 for a few days and is amazed by the experience. With this model he has managed to complete projects such as east of the isochronic map that previous models had never solved, and it has done it almost “the first time”. In one of the cases Fable 5 worked for 9 and a half hours straight to produce a code called Concord of data analysis. Their conclusions are compelling: Last year (when working with GPT-5 Pro) I called him “work with a magician”: you recite the spell and something happens. With Fable, the spell has become so powerful that I’m no longer sure I’m the wizard. I feel more like a patron. I describe what I want, pay for it and evaluate the result. The conspiracy takes place somewhere I can’t see, in hundreds of small decisions over which I never have a say. Work has gone from being a process to being a result. I no longer direct; charge. The criticism is unanimous. Andrej Karpathy, who recently signed by Anthropic, commented on X how this is a qualitative leap that for him is of the same relevance as the one that Claude 4.5 represented in November. That model began the overtaking of OpenAI: this puts it even further away (at least, for now). Other tweetersemployees or not from Anthropic, make it clear that this is an important leap in the capabilities of AI models. It’s only been a few hours since the launch, but everything points because we are indeed facing a notable leap in quality. Consume tokens like there’s no tomorrow. But in the face of that fascination, the criticism. Discussions on Reddit reveal how users who have started using it have quickly detected the problems associated with this release. The first of them: Claude Fable 5 burns tokens like there is no tomorrow. Its consumption is enormous, and the quotas for Pro and even Max accounts run out in minutes if we use the model intensively. If it already seemed to us that we were exhausting the limits of the free or quick payment accounts, with Claude Fable 5 that feeling worsens: Fable 5 is fantastic, but we can barely use it often with the Pro or Max plans because those dreaded messages about waiting X hours to continue using it quickly appear. Extremely cautious. Anthropic has been very serious about avoiding misuse of Fable 5, and as soon as it detects anything suspicious it “brakes” and “downgrades” the model so that at that moment the one that is activated is Claude Opus 4.8 (which is not bad at all). The problem is that users are detecting that the model takes completely harmless prompts as dangerous. Although in Anthropic indicate Although these security measures are activated in less than 5% of sessions, what users are detecting is that they are activated much more. Fable 5 can get silly. Not only that: Fable 5’s own design means that if it encounters a prompt that it detects as dangerous, the model tries to avoid the response and automatically reduces your capabilities (‘nerfing’) without you knowing. It gets a little sillier on purpose, so to speak. As Anthropic itself explains on the system card, We have implemented new measures that limit Claude’s effectiveness in requests related to the development of cutting-edge large-scale language models (LLMs) (for example, in creating pre-training pipelines, distributed training infrastructure, or designing machine learning accelerators). Using Claude to develop competing models already violates our Terms of Service, but enforcing this restriction through our security measures prevents giving an advantage to those users most willing to violate those terms. Unlike our cybersecurity, biology and chemistry interventions, and distillation attempts, … Read more

“Investing in the development of full electric cars would be an expensive hobby”

by

something like It happened to Luca Cordero di Montezemolo It has happened to Stephan Winkelmann, CEO of Lamborghini. He did not want to say but he said when asked about the new Ferrari Luce and all the controversy that has surrounded the Italian company’s first all-electric launch. And Lamborghini, unlike those from Maranello, canceled its all-electric project a long time ago. And both positions have their reason for being. “The right way”. It is the one they have taken at Lamborghini, according to Stephan Winkelmann. Those three words are part of the answers he has given to CNBC in relation to the new Ferrari Luce. Although Winkelmann assures that “each brand, each company has to decide for itself,” he has not hesitated to defend his position. And the head of Lamborghini considers that canceling its first fully electric car has been “the right path.” According to their internal reports, they claim that interest in a completely electric car from Lamborghini had slowed down and that is why they decided to stay with plug-in hybridization. “An expensive hobby”. This is how resounding Winkelmann himself was a few months ago when he confirmed that the project for Lamborghini’s first electric car had been cancelled: Investing heavily in the development of full electric vehicles when the market and customer base are not ready would be an expensive and financially irresponsible hobby towards shareholders, customers and towards our employees and their families. The words were collected by media such as Motorpassion and they emphasize the purchase intentions of Lamborghini customers, who They still prefer the company’s V8 and V12 engines. The company, however, has used its research on the electric car to carry out the Lamborghini Revueltoits first plug-in hybrid. Because?. As we told you during our introduction to the Lamborghini Revueltothe company was always very clear that electricity had to be a means to increase the sensations on board and improve dynamics, not aiming for a more language ecofriendly. This decision, like that of canceling its first electric car, has its own internal logic within a company like Lamborghini, which clearly opts for hypermuscular and hypermasculine cars where sportiness is almost its only reason for being. The only concession they have made is the Lamborghini Urus and its creation falls within the Volkswagen Group’s logic of cost utilization. a lot of sense. If the approach proposed by Lamborghini was that of an electric supercar, the truth is that there does not seem to be a market for this type of car. Mate Rimac, CEO of Rimac and creator of, perhaps, the sportiest electric car in the world, complained that political pressures to jump to electric cars They were precisely slowing down the potential sales of their electric cars. Beyond the fact that the customer may miss the sound of a V12 engine and the feel of a gearbox, the truth is that if the average driver is forced to skip the electric car, driving a combustion supercar will be even more elitist. It is very likely that more electric supercars will arrive but right now the context is against them. The public for this type of car seems to be revolting against the regulations that, supposedly, force them to jump to electric cars. By pure physics, the electric car needs to be much heavier than a combustion car right now. And finally, obviously lacks that sensory part which can only be associated with the sound and smell of a combustion engine. And the Ferrari Luce? It is logical that Lamborghini defends its position and claims that its customers are not looking for an electric car, but the public profile is different between Lamborghini and Ferrari. Or, what is certain, Ferrari is trying to catch a different audience. The Ferrari Luce is not an electric supercar, it is not an aggressive and aerodynamic sculpture on wheels as has been the norm in its history. It is a car designed to send the message that whoever has it is up to date and embraces innovation and groundbreaking products. Since we saw the interior of the car it is something that seems more than evident. The fact that the car was shown in a light blue color and without a trace of moving videos underlines that we are looking at the launch of a car as a fashion accessory for walking comfortably through the center of any city without the discomforts typical of a supercar. Click on the image to go to the original tweet A little pull. Although Stephan Winkelmann says he does not mean to say, the truth is that he says a lot with his response. Despite not wanting to get into controversy, his defense that Lamborghini customers do not opt ​​for this type of car is a way to distinguish the two types of customers. A reaffirmation of Lamborghini’s identity. It adds up Lamborghini’s social media post coinciding with the launch of the Luce, which reads “proud to keep you dreaming” or “proud to keep your dreams” and four attached images of a Lamborghini Revuelto in a tone of blue very similar to that used by Ferrari for the presentation of its Luce.

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. It can be controlled from your mobile phone to program routines and is capable of capturing odors, bacteria, viruses and larger particles. Philips 2200 Series Air Purifier The price could vary. We earn commission from these links Dyson Purifier Hot+Cool HP1 Dyson purifiers are quite well known for the format that many of their models have, such as the Dyson Purifier Hot+Cool HP1. This purifier with a HEPA filter is capable of capturing particles down to 0.1 microns thanks to its H13 filter and can also be controlled from a smartphone.

If you thought the blue zone in your city was expensive, wait until you see what it costs to moor a yacht at the Formula 1 GP in Monaco

by

The Monaco Grand Prix is, by far, the most glamorous career of the Formula 1 World Championship. Not so much because of the fact that each of its curves keeps a memory of the most successful drivers, but because of the enormous showcase of luxury and opulence when celebrating with one of the most exclusive ports in the world. Not everyone can access the most exclusive spaces at the Monaco GP. Beyond the VIP stands, the real epicenter of luxury It is on the yachts moored in front of the circuit. The mooring of a superyacht during that weekend costs a real fortune, only affordable for the richest in the world. In fact, not even the world’s great fortunes, such as Jeff Bezos, They have a guaranteed position among the privileged few who can afford to watch the race of Formula 1 from the deck of your superyacht. Three million for a front row seat During the week of the Grand Prix, Port Hercule stops being a normal port and becomes a meeting point for the greatest fortunes on the planet and their yachts. Whether you like Formula 1 or not is secondary. The week before the Grand Prix, the parade of enormous superyachts begins, such as the Symphony by Bernard Arnault, founder of LVMH, who take positions highlighted in the Monegasque port. The specialized medium Yacht Harbor estimated that the 2017 test brought together yachts valued at more than 2,000 million euros in Port Hercule. Kismet superyacht, 122 meters long However, not having your own yacht is no excuse for not enjoying a front row seat at sea to enjoy the only Championship race that can be seen from the deck of a luxurious superyacht. Yacht rentals during the race test week skyrocket. The portal of boat rental luxury Cecil Wright offers those types of services and allows you to rent the Kismeta true floating mansion for the modest price of three million euros for one week. While on the streets of Monte Carlo the single-seater engines make the most of their performance, inside the Kismet Up to 12 guests can be accommodated in eight suites. The yacht is equipped with every detail so that guests only have to relax in its Balinese-inspired spa, which includes a hammam, sauna and cryotherapy chamber, waterfall shower and chromotherapy bathtub, gym and yoga studio. One of the covers of Kismet In addition, it allows you to experience all the excitement of the race from any of the jacuzzis on its luxurious decks, and all of this is attended by a crew of 36 people. “Parking” at a Monaco GP Once you have rented the right superyacht to blend in with billionaires and royalty, all that remains is to find a mooring for the yacht. Kismet. Port Hercule is the only port with adequate depth for mooring superyachts of that category. This port offers about 700 berths, but the most sought-after place is the so-called Trackside Zone, where the boats are located next to Quai des États-Unis, Quai Jarlan and the first two positions of Quai U. That is, in the mooring line closest to the circuitwhere the single-seaters pass just a few meters from these yachts. According to the table of Port of Monaco ratesthe price of the mooring is calculated based on how close it is to the runway and the length of the superyacht. Docking a yacht in the port of Monaco during the race ranges from 5,668 euros for a yacht of less than 19 meters in the Port of Fontvieille area, the furthest and without vision of the track, to tripling its price as we get closer to the track, with a mooring price of 16,087 euros for the same 19-meter yacht. Mooring Zone 1 is at the end of the tunnel straight, just when the cars must brake. Passing mooring zone 2, from which you can see the chicane of the Pool areato the Trackside Zone (zone 1) implies a price increase of 25.7%. During the Monaco Grand Prix, mooring a superyacht like the Kismet122 meters long, in the Trackside Zone (zone 1) It can cost around 160,000 euros only for docking during Grand Prix week. Its high price is justified because its proximity turns the Trackside Zone into a kind of floating stand. The yachts are in front of one of the most recognizable parts of the track, right where the cars leave the tunnel and launch towards the Nouvelle Chicane area, one of the classic images of the Monaco Grand Prix. It is a point where the drivers must reduce their speed to follow the curve and face the Pool section, so the millionaires see them pass at a slower speed and the single-seaters can be seen in more detail. Without a doubt, the most millionaire form of watch a formula 1 race. In Xataka | Madrid has been fighting for its F1 Grand Prix for years.

They promised us Rapunzel’s hair with very expensive cosmetics. Science says the real secret has been in your kitchen for millennia

by

Mythical representations of women, whether Botticelli’s Venus, the Hindu goddess Lakshmi or the maidens of Arthurian legends, often share an unmistakable trait: long, flowing and seemingly unattainable hair. It’s easy to think that such lengths are confined to the realm of mythology, untouched by the harsh reality of split ends and frizz. However, just swipe through TikTok or Instagram to find content creators sporting hair that would rival Rapunzel herself. Many of these influencers They promise that your hair has grown at a dizzying rate thanks to a specific technique: hair oiling or hair oiling. But, faced with shelves full of exotic formulas and luxury serums, an inevitable question arises: do we really need expensive products or has the ancient secret always been hidden in our kitchen in the form of olive oil? The resurgence of an ancient ritual. Although the term hair oiling It may sound like a modern invention packaged for Generation Z, the reality is very different. This practice was not born yesterday under the ring of light of a smartphone. Hair oiling is a technique deeply rooted in ayurvedic medicine from India, with Sanskrit texts from more than 5,000 years ago that already recommended infusing hair with natural oils to restore its shine and relax the mind. Likewise, in ancient Egypt also ointments were used based on animal fat or castor oil for similar purposes. What has changed then? The showcase. He hair oiling In a few months it has gone from being a “legacy trick” to an essential aesthetic ritual. Social media has choreographed it into a highly recognizable scene that includes a slow massage, meticulous application of oils before washing, a warm towel, and blow-drying to an incredibly shiny finish (glossy). Among the avalanche of coconut, argan and jojoba oils, olive oil has begun to reclaim its throne, not only because of its accessibility, but because it has historically been the cornerstone of Mediterranean cosmetics and the basis for extracting the properties of countless medicinal plants. The science behind the shine. Beyond visual aesthetics, the big question is whether slathering your hair in oil really works. The answer from science is a resounding yes, although with important nuances. Rocío Lajarín, doctor in Pharmacy and CEO of Alma Secret, explains in GQ that hair is made up of 90% proteins, mainly keratin. “When we use oils with structural affinity, we manage to reduce protein loss and reinforce the resistance of the hair shaft,” he says. The portal Healthline adds that regular oiling reduces “hygral fatigue” (the repetitive swelling and drying of the hair fiber when wet), acting as a cement that protects the cuticles. If we focus on “liquid gold”, clinical studies support its many benefits: Deep hydration and elasticity: An investigation of the Journal of Cosmetic Science demonstrates how olive oil It penetrates the hair fiber thanks to its high content of essential fatty acids, significantly improving hydration and resistance to breakage. A cocktail of vitamins: Virgin olive oil rejuvenates hair because it contains vitamin E, vitamin C (which stimulates collagen formation) and vitamin A (enhancers cell regeneration). Shield against damage and the sun: The International Journal of Trichology emphasizes that extra virgin olive oil contains hydroxytyrosol, a polyphenol that fights free radicals and cellular damage induced by UV-A rays. In addition, it is highly effective in reducing damage after subjecting hair to chemical processes such as dyes. Antifungal action: The same International Journal of Trichology points out that olive oil has an inhibitory influence on fungi that attack hair, such as Microsporum gypseum. The great debate: Does it make hair grow? This is where dermatology collides with internet myths. Dermatologist Andrea Combalia warns in Telva that at hair oiling “Many benefits are being attributed to it that are not real, such as hair growing faster or increasing its density.” Doctors consulted in Cleveland Clinic They agree that growth rate and thickness are predetermined by genetics, age and hormones. Oils prevent breakage (allowing length to be retained), but do not accelerate the growth phase from the follicle. However, dermatologist Ana Molina contributes in Trends a fascinating fact. It has been observed that the phytoestrogens present in olive oil can have an antiandrogenic effect by inhibiting the enzyme 5-alpha-reductase (which converts testosterone into DHT). Since DHT causes miniaturization of follicles in androgenetic alopecia, “phytoestrogens may help prevent or slow its progression.” Roots or just tips? This is the point of greatest controversy. Oiling the scalp before washing protects the lipid barrier of the skin against the aggressive surfactants in the shampoo. However, hairdresser Daniel Gil in Marie Claire and Dr. Steven Walker in GQ They are blunt: if you have an oily scalp or suffer from seborrheic dermatitis, you should avoid applying oils directly to the roots. Dr. Shilpi Khetarpal of the Cleveland Clinic confirms this: if you are prone to dandruff, applying oil can worsen the problem by feeding the fungus Malasseziacausing more inflammation. In these cases, the hair oiling It should be strictly from medium to ends. A ritual with common sense. At the end of the day, olive oil is not going to rewrite your hair genetics or magically transform you into a Renaissance painting. What science tells us is much more pragmatic and, at the same time, liberating. The true value of this trend lies in understanding hair care as a ritual that respects our natural hair structure, and not as a compulsive accumulation of synthetic cosmetics. Olive oil is a powerful, accessible and dermatologically endorsed tool to defend our hair from pollution, the heat of straighteners and daily wear and tear. Applied with common sense, the liquid gold of our Mediterranean diet is also confirmed as the best cosmetic in our bathroom.

We Spaniards are changing fishmongers for fish on a platter. And it is costing us very expensive

by

When your grandparents wanted to buy fish, they might have found more or less variety, but they had it easy: they went to the market or the fishmonger, asked questions, chose, paid and returned home with the purchase. Today things are somewhat more complicated. Or not. with consumption in low hours and food spending increasingly concentrated In supermarkets (to the detriment of neighborhood stores), it is increasingly common that instead of buying salmon, sea bream or any other fish on a counter, we take it from a refrigerator, already scaled, filleted and served on trays. The question is… Does that make it more expensive for us? What has happened? that the OCU just responded to a question that you may have asked yourself more than once if you usually consume packaged fish from the supermarket: Are you paying a premium? Would that filleted fish be cheaper if you bought it in the fishmonger’s section instead of on a tray? It is an interesting question if we take into account that Mercadona, the chain with higher market share of the country and agglutinator of more than 30% of the food distribution business in some parts of Spain, has decided retire their fish counters and bet on the sale of this product already prepared, packaged and arranged on trays. What has the OCU found out? In general terms, it is (indeed) likely that you are spending more money by taking home already packaged merchandise instead of buying it at the supermarket fishmonger. After carrying out a study in a dozen chains throughout April, the OCU concluded that “fresh fish sold packaged is up to 30% more expensive than that purchased at the fishmonger if they are small varieties, already cleaned and filleted.” That last nuance is important because the organization’s technicians verified that the percentage goes up or down depending on the type of product we are talking about. In some cases the extra cost of packaged fish compared to that sold over the counter shoots up to 45%. In others it narrows so much that it is almost imperceptible. “The answer is not as simple as it seems: in some cases, especially for smaller or portioned fish, we do pay a lot more to buy clean fish on a tray, but in others, for larger ones, there is almost no difference,” details the OCU. Can it go further? Yes. To begin, it is useful to know how your study was carried out. As recognizes the OCU itselfthe analysis is not as simple as writing down the cost (euros per kilo) of each product and then comparing. There are chains that only sell certain varieties of fish through a single channel (counter or trays). As if that didn’t complicate things enough, there is another key handicap: trays of filleted and packaged fish usually offer 100% edible product; That is, without bones, heads or any other disposable part, something that can happen with whole pieces from the fish market. And how did they calculate it? How can we compare the prices of trays of already cleaned fish with those we see in fishmongers, which usually show the cost €/kg of whole pieces? To solve it, the OCU was based on estimates from the Spanish Nutrition Foundation that they conclude that the edible part of the fish usually represents more or less between 55 and 67%, depending on whether we are talking, for example, about sea bream or sea bass. As for the chains, the OCU set in Ahorramás, Alcampo, Aldi, BM, Carrefour, Dia, Hipercor, La Despensa, Lidl and Mercadona. If we talk about gender, the analysis focused on four species frequently consumed in homes: sea bream, sea bass, hake and salmon. For referencethroughout the year between October 2024 and November 2025, we Spaniards consume 0.56 kg of sea bream, 0.55 of sea bass, 1.44 of salmon and 1.54 of hake. Do those details matter? Yes. Because thanks to them we can better understand how the gap between the price of fish on the counter and on a tray widens or narrows depending on the product we are talking about. The clearest cases are represented sea ​​bream and sea bass. In the first case (gilthead) the OCU calculates that merchandise sold packaged is on average 27% more expensive. And at the counter we also pay for the amount of merchandise that is wasted after weighing the complete piece. In some supermarkets that percentage even shot up to 47%. The case of the sea bass is even more egregious. The surcharge detected in filleted products served on trays is 45%. Is it always like this? Things change considerably when we talk about hake and salome. If we want some slices or loins, there are no big differences depending on whether we ask the fishmonger at the counter or go to the supermarket refrigerator to buy them in trays. A hake cut and prepared on the counter came out in April for €17-25/kgwhile on a tray it was charged at €18-25/kg. The salmon slices or loins also cost practically the same (€20-23/kg) both in the fishmonger and in boats. What is the conclusion? “The conclusion is clear: in small fish, the greater the handling, the more expensive the fish on a tray becomes compared to selling on the counter. In preparations with less handling, the premium is much lower, if not residual,” ditch the organization. In short: there is a premium, although it is not always nor is it equally forceful in all cases. It depends on the type of fish and also the level of preparation we want. “In small and filleted fish, convenience does pay.” Better one or the other? The OCU admits that the trays have “pros and cons” for both consumers and supermarkets. Among the first, the most obvious is speed and comfort. One of its biggest drawbacks is the loss of the figure of the fishmonger, crucial for advising the client, and the generation of waste. The organization also warns … Read more

Graphing calculators are very expensive, so a 15-year-old boy from Almería has declared war on them with open source

by

It was 2003 when I started college with great enthusiasm and an old Casio calculator from high school that I ended up replacing shortly after with a Texas Instruments TI-86 graphing calculator. At that time it cost me 150 euros, but I spent it because there was no other option and it was going to make my life easier with graphs and matrices. My old TI-86 is already a relic, but those who start engineering this 2026 will spend at least those 150 euros on a more current model like this either this other one from HP. They have a slightly more modern aesthetic and a color screen, but the essence and prices have barely changed. So to a young developer from Almería an idea has occurred to him: build a professional level scientific and graphing calculator for about 20 euros using open source software. And as its creator, Juan Ramón (alias El-EnderJ), explains, at 15 years old he still doesn’t need it: “I did it simply because of that great injustice.” A DIY calculator with open source. The project is barely a couple of months old and its premise could not be more ambitious: NumOS (its operating system) runs on the ESP32-S3 microcontroller and aims to break the monopoly of commercial models that cost around 150 euros. It is not a mobile app or a website: it is a piece of physical hardware that the user assembles and programs from scratch. Knowing how difficult it is for the education system to accept a DIY calculator for exams, El-EnderJ has in mind a “factory-sealed version that is completely legal.” Disclaimer: the final product will use ESP32 S3 N16R8 and a 3.2″ IPS screen. Grapher app. Via: GitHub Why is it important. The educational calculator market is controlled by an oligopoly: Texas Instruments, Casio and HP, with devices whose hardware has not been significantly renewed for decades and a price range that has neither changed much over the years nor differs too much from each other. But the underlying problem is also one of access: this is the case of fantastic free and quality tools such as GeoGebra and Desmos. As El-EnderJ explains: “To use them you must use a mobile phone, a tablet or a laptop, which is completely prohibited in most classrooms. The educational system requires dedicated devices that do not have an internet connection to avoid cheating.” On the other hand, on a technical level it is notable that NeoCalculator integrates a complete CAS engine within such a low budget as manufacturers such as Casio, HP and TI reserve only their high-end models. And be careful, this engine shows the intermediate steps of derivatives, integrals and solving equations. The eternal? calculator oligopoly. Juan Ramón says that, encouraged by what he saw people doing with graphing calculators (like programming), he looked up the price and was surprised: “I was shocked when I saw that a calculator from more than 30 years ago cost more than 150 euros. So I looked a little more and realized that the cost of producing them is below 20 euros, so you are paying a 130-euro premium.” Free software has been democratizing tools that were previously either expensive or exclusive for decades, but in hardware everything has been slower. The clearest precedent is NumWorksthe French calculator founded in 2015 that was the first to completely open its source code and allow anyone to modify its operating system. NeoCalculator goes one step further: not only is the software free, but so is the hardware design. From Shanghai to Almería: the ESP32-S3-BOX-3 chip from Espressif How it works. The base is the microcontroller ESP32-S3which according to its official documentation incorporates a dual-core Xtensa LX7 processor capable of running at 240 MHz, with 512 KB of internal SRAM, Wi-Fi and Bluetooth 5 connectivity, as well as support for vector instructions aimed at accelerating neural networks and signal processing. It is a chip designed for IoT converted into the brain of a high-performance calculator. El-EnderJ is critical of what it replaces: “The ESP32-S3 is from 2020; the Zilog Z80 of the TI-84 Plus is from 1976. There is a clear difference.” The mathematical core of the project is not development from scratch, but sophisticated integration. “The biggest challenge has been putting the Giac engine, which is the same one used by the HP Prime, in a chip that has thousands of times less memory than a computer.” In fact, Giac is an open source symbolic calculation engine originally developed at the University of Grenoble and indeed, it is the engine that equips the HP Prime G2. For the graphical interface, the project uses LVGL, an open source embedded graphics library widely used in the industry. Combining hardware SPI with LVGL, NeoCalculator maintains a smooth interface at 60 FPS, which is a demanding performance target for a microcontroller in this price range. Yes, but. The incipient project of the Almeria developer has important technical and regulatory limitations. The most important is precisely the connectivity of the ESP32-S3, something strictly prohibited in exam contexts. This implies that in its current state NeoCalculator could not be used in official university exams (not the EBAU, which generally restricts graphic models). On the other hand, this fantastic project is still very green: it lacks an integrated physical keyboard and is still pending receipt.

Jeff Bezos’ superyacht is one of the largest and most expensive in the world. Now it is for sale for a curious reason: parking

by

At more than 127 meters in length, Jeff Bezos’ superyacht is one of the largest in the world. In fact, it is so big that even caused some problems to its Dutch builder when he was trying to take it out to sea from the shipyards. The ship was so large that it did not pass under a bridge, over which it was even considered disassembling it. It was just the first of the problems that Jeff Bezos was going to have with the size of his ship. According to advanced Page Sixnow the millionaire would be considering putting the Koru up for sale. The reason has nothing to do with the price or its maintenance. The problem is that the boat is so big that it doesn’t fit almost anywhere, and wherever it manages to get in, everyone instantly recognizes it. A huge boat with a price to match. The Koru is a three-masted schooner more than 70 meters high. built by the Dutch shipyard Oceanco and delivered to Bezos in April 2023. At 127 meters in length, it was for a time the second largest sailboat in the world and is currently among the largest in its category. In fact, it is so big that when it approaches Miami, Jeff Bezos’ usual place of residence since his move in 2025, the luxury sailboat must moor. along with large cargo ships and oil tankers because it doesn’t fit in the nearby marinas. Its construction cost around 500 million dollars and is accompanied by a support ship called Abeona, valued at another 75 million dollars. According to calculations of Robb Reportkeeping both vessels in operation costs about $30 million a year. Practically pocket change for someone who could spend a million dollars a day and still it would take more than 548 years in ruining. The problem: parking. According to a source close to the millionaire consulted by Page SixBezos considers that the yacht has become “too big to manage.” But it’s not just about the size: the Koru has become so popular thanks to its owner, that it is impossible to maintain privacy where it anchors. Hide a sailboat the size of a ten-story building off the coast it is not a simple task. One of the drawbacks of the Koru’s size is that, for example, the millionaire could not even get close to it. the marina of Monte Carlo during the last Monaco Grand Prix, a sporting event in which millionaires watch the cars pass by without even getting off their yacht. The Koru, on the other hand, had to settle for remaining anchored far from the moorings and use a small boat to get to land due to its enormous proportions. Something similar happened during the celebrations prior to the Jeff Bezos’s wedding and Lauren Sánchez in Venice, where the Koru had to remain anchored in the middle of the Venetian lagoon because it didn’t fit at the moorings near Venice. A sale without an official price and many unknowns. At the moment the sale has not been confirmed by any intermediary or by the founder of Amazon himself, and it is also not clear if the Abeona support ship will be part of the sale agreement. What does seem certain is that Jeff Bezos could be tired of all the inconveniences involved in operating a boat of that size, and would be considering buying a somewhat more discreet and manageable superyachtwhich does not cause so many “parking” problems.
