Florida has an iguana problem and the coldest winter in years, so it has euthanized more than 5,000 frozen iguanas

by

In the Iberian Peninsula we are having one of the winters with more rainfall in recent yearsbut in the United States they are not exactly having a mild winter either. New York has arrived register colder than in Antarctica and not even the state of the sun has been saved: Florida has broken a cold record of more than 100 years. Thus, Miami or West Palm Beach have fallen below 0°C, something that It hasn’t happened since 1909. This extreme cold literally freezes the iguanas. And that has made it very easy for the Florida authorities to “euthanasia” 5,195 specimens Florida has a serious problem with iguanas. As happens in Spain with the catfishes either in Italy with blue crabs (among other parts of the Mediterranean), the United States has invasive species like the Asian carp, which bothers it so much that They have come to electrify the riversor the iguana, which mainly affects southern Florida. In addition to biodiversity problems derived from introducing an outside species into an ecosystem, altering the trophic chain or that its feces are natural carriers of salmonellais that they constitute a real danger to infrastructure: they build burrows up to 24 meters deep, damaging sea walls (a 1.8 million dollar problem in West Palm Beach), building foundations and even blackouts. Not to mention the risk that an iguana falls from a tree to the head or the hood of your car. Friendly reminder that iguanas can come to measure two meters long and weigh more than 13 kg. It’s raining iguanas. Literally. You probably read the above with surprise because, well, from time to time a little bird falls, but a tremendous iguana is less common. The iguanas They arrived in Florida in the 1960s. and since then they have moved quietly through courtyards and canals. The Sunshine State has a subtropical climate and iguanas are cold-blooded reptiles, but for much of the year, they adapt. But winter comes, especially a winter as cold as this one, and the iguanas are stunned by the cold. They are ectothermic speciesthat is, their body temperature is strongly determined by the environment (they do not generate their heat, as mammals do), so they freeze. This cold stunning affects internal processes such as metabolism, breathing or heart rate. And this is what leads them to fall from trees because they are in standby and lose their grip. A chance to get rid of them. So the Florida Fish and Wildlife Conservation Commission (FWC) has taken the opportunity to implement executive order 26-03which temporarily allows anyone to pick up one of those cold-stunned green iguanas without needing a permit to bring it to authorities. In the first two days of February, Residents brought 5,195 copies. Subsequently, they were sacrificed following American Veterinary Association guidelines (AMVA). Or from a technical point of view, they “euthanized” them. Animal welfare vs pest control. According to the FWCnon-native reptile species such as green iguanas or Burmese pythons are only protected by animal cruelty laws. The procedure is known as “euthanasia” insofar as the method of death must be irreversible, rapid and painless. Precisely at that moment in which they are lethargic is the moment considered the most humanitarian to act.

We have been experiencing a great war between the Xbox and the PlayStation for 25 years. And that’s wonderful: Crossover 1×38

by

The clear things and the thick chocolate: I’m from Xbox. I have been almost always, although my first real console was the original PlayStation. Then, for various reasons, I decided to try the original Xbox and loved it, and have ended up owning all of its successors. But that doesn’t stop me from knowing that Spain is a country of Play. I respect and accept it, but what I also value is that this “console war” continues to be so active, because that competition not only allows us some fun and laughter with friends – “Do you really have an Xbox!?!?” – but above all because it has allowed both evolve amazingly. And precisely that war between the Xbox and the PlayStation we talk about in this installment of Crossover, in which both Jose and I We talk about our experiences and the history of these platforms accompanied, of course, by Jaume, who moderates and as always asks the right questions. Thus, we review the birth of the first PlayStation and Xbox and how that completely changed a market that previously seemed dominated by Sega and Nintendo. The latter has never directly entered into competition with Sony and Microsoft, and has chosen a different path and in which it has certainly done extraordinarily well. But what is clear is that the evolution of the Xbox and the PlayStation marked us all and in that review we talk about all those decisions, how each of the generations fared and what the future may hold for us. The final question, “Who won the console war?”may have a valid answer for the current moment, but the best of all is that we are facing platforms that are absolutely alive and that are preparing the most interesting news in the short term. Not only of them, of course, also with promising projects like the Steam Machine. Meanwhile, whether you are from Xbox or Play, we have a single message. Long live video games. On YouTube | Crossover In Xataka | There is brutal competition for our attention. And there is someone losing that battle in a bloody way: the consoles

Mercadona and the white label had been setting the course for supermarkets in Spain for years. Until the “ultra low cost” arrived

by

When we Spaniards go out shopping we value above all two factors. The first, proximity. The second, the price. Even above the quality. It is not at all surprising if we take into account that we come from a inflationary crisis and there are items of common consumption (cocoa, coffee either eggs) who have experienced a real storm in recent months. The chains know how much they are risking with each euro and have acted accordingly. For example with a bet on the white label that has been especially good to Mercadona. There is, however, another strategy that has been gradually making its way into the world. retail Spanish, one also focused on prices, but that does not rely on white label or short assortment: supermarkets “ultra low cost“. “Ultra low cost“? Exact. It sounds somewhat far-fetched (almost, almost cacophonous) but that is the label that best defines certain supermarket chains that have focused their strategy basically on product discounts. double digit. After years of inflation and with costs becoming a decisive factor When families decide where to shop, most chains try (to a greater or lesser extent) to be competitive in prices. In fact in the rankings Cheaper stores usually include brands such as Alcampo, Family Cash or Aldi. In the case of super “ultra low cost“The price is, however, more than just a front on which to compete. It represents the great differentiating factor. And it is to such an extent that it conditions the approach, the offer and the way the chain operates. In a recent article, Five Days reviewed the billing data of two relatively young firms that fit this pattern: Sqrups and Primaprix. What differentiates them? That in a sector (that of supermarkets) in which it seemed that everything had been said, with Mercadona expanding your domain and the white label gaining market sharethe “ultra” chains low cost“have found an alternative path of growth. Their strategy involves offering items from recognized brands (nothing from Hacendado, Deliplus, Auchan or similar), but with surprisingly low prices. As an example, Sqrups boasts of offering its customers “significant discounts” that move between 30 and 80%. How do they work the miracle? With your business model. More like its supply model. Unlike most supermarket chains, they supply surpluses that are left ‘off the hook’ or have no place on the shelves of companies such as Carrefour, Eroski, Mercadona or Hipercor, among others. These are surplus stocks, items that do not quite work, merchandise that has been left out of the circuit due to a change in packaging or not meeting presentation standards… In short, items in good condition that manufacturers need to liquidate and cannot (or want) to distribute through ‘conventional’ chains. Their destination ends up being Sgrups or Primaprix, where they add to a catalog marked by rotation, speed and discounts. But… How do they do it? “Large international brands usually have surplus stocks in their warehouses, left over from promotions (Christmas, summer, events…), from new launches or simply products with a much lower price in one country than in another. At Primaprix we travel throughout Europe hunting for these opportunities,” details the companywho remembers that he opened his first store in Madrid in 2015 and in just ten years he has built a network of 260. Sgrups’ explanation is similar. “We recover products that, under normal conditions, distribution throws away,” clarifies its general directorRaúl Espinosa, who boasts that thanks to its discounts the chain sells products with prices much lower (50-80%) than those on the market. The company ensures that its assortment comes from three sources: “production surpluses, image changes and quality control.” It also incorporates “short-dated” products. “In the last year we have rescued more than 26 million products, preventing them from being destroyed and giving them a second chance for consumption,” the company specifiesborn ago just over a decade and that works with food, but also drugstores, stationery and hygiene items. The big question: why? Because this formula has allowed them to connect with a part of the market and expand in a sector, that of retail Spanish, in which a small number of brands have been expanding their dominance. “Companies like Sqrups or Primaprix break the differentiation with the rest of the operators thanks to this supply model,” explains to Five Days Javier Pérez de Leza, good knowledge of the sector. “Mercadona, Lidl or Aldi have dedicated themselves to a type of discount that leaves room below, because the price trend is upward. You can be much cheaper than all of them, although with risks.” What risks? One (fundamental) is the pressure that operators in the sector can exert to reduce the surpluses that these chains feed on, although it is not the only limit that the model of companies like Primaprix faces. Relying on stocks makes it very difficult to guarantee the continuity of an ever-changing assortment. Furthermore, the fact that customers encounter different products every so often may increase their interest in visiting stores but also complicates such basic issues as logistics. What do your accounts say? That neither of the two chains are doing badly at all. Primaprix data we know them also thanks to Five Dayswhich a few days ago revealed that during the 2024 financial year the company had a turnover of 347 million euros. Maybe it’s far from billions from Mercadona, but it represents a year-on-year growth of 24%. If we look further back, the company’s sales quadrupled between 2020 and 2024, a period during which it went from managing 110 stores to 245. Now it is on its way to 300 establishments. The key: your business modelwhich is nourished by the surpluses accumulated in the warehouses of large manufacturers. Your catalog is completed with purchases you make in other countries, looking at prices, discarded items despite being completely suitable for consumption, or products that will expire soon. A bet not very different from what fashion or furniture outlets have been making for years. They are merchandise (many … Read more

23 years later, Western Europe’s largest swamp is completely full

by

When in the mid-1950s, someone thought about building a dam in one of the driest areas of Portugal, the criticism was very simple: make a reservoir in Alquevassimply absurd: “it will never be filled.” And that prejudice meant that (for more than fifty years) the project was put in a drawer. But, at the end of the century, the Portuguese country decided to take it back and its floodgates closed in 2002. What happened next showed that those critics had no idea. A huge work of engineering. Of course, the skepticism was well founded. ‘Alqueva’ means precisely ‘fallow land’, ‘desert’. But that did not mean that it was meaningless, quite the opposite: that a much greater ambition was needed. And that’s what they did: with a total capacity of 4,150 hm³ and a surface area of ​​250 km², it not only regulates the Guadiana. It provides water to supply the consumption network (200,000 inhabitants), to produce energy (520 MW) and to irrigate hundreds of thousands of hectares (130,000, it seems). It is the largest reservoir in Western Europe. A monster that now has to be unpacked. That is what is striking, that had to unpack. Not because it’s the first time: between 2010 and 2013 he did it on several occasionsbut the deep drought of recent years meant that there was no fear that it would not happen again. Although it is happening: these days, Alquevas has been draining at the rate of an Olympic swimming pool every two seconds. Is there much left to do? Although seeing the monstrous Alquevas reservoir full it is inevitable to think about what more projects are still to be done, the truth is that we do not have much room for maneuver. The majority of “easy” reservoirs are already built and most of those that could be built would have great technical, social and economic problems to carry out. So we will have to go a little further: think about how we approach this possible “new normal” if it ever occurs.

We have been searching for the origin of life in hot puddles for years. Bennu has shown that radioactive ice works just as well

by

When the capsule OSIRIS-REx mission landed in the Utah desert in September 2023, NASA knew it had a treasure on its hands. We are talking about a bit of black dust that was collected millions of kilometers from Earth and that was about to rewrite one of the most important chapters of science: the origin of life. What we knew. Until now, the predominant theory regarding the origin of life told us that for “cook” all the basic components of life, such as amino acids, heat and liquid water were needed to make a kind of hot chemical soup. However, science has just flipped the script: the bricks of life They are not only formed in heatbut they can be born in the most extreme cold and under gamma radiation. And that completely changes our understanding of how we got here, and also of the possible presence of life in any corner of the Universe. The importance of Bennu. Definitely is the protagonist of this whole story, and it is nothing more than an asteroid of about 500 meters in diameter which functions as a fossil from the early solar system. But the most interesting thing is that it is approximately 4.6 billion years old, the same age as the Earth, although, unlike our planet, its surface has not melted or been drastically altered by geological processes throughout its ‘life’. And little by little we are learning more about this asteroid thanks to the samples brought by OSIRIS-REx that had already been confirmed in preliminary analyzes an unusual abundance of carbon, nitrogen, water and organic compounds. But what the team led by Penn State University has now found goes one step further. The surprise. This same team, when analyzing the isotopic composition of the amino acids present, especially glycine, came across a chemical signature that did not fit with the classical theory of formation in hot water. A radioactive freezer. Until now, we thought that amino acids in asteroids were formed primarily through aqueous alteration processes: ice melts from heat, liquid water interacts with rock, and voilacomplex organic chemistry. However, science now suggests that liquid water is not necessary for amino acids, an essential molecule of life, to form. Simply from simple ice they can arise without much problem. And there are many of these in the universe. The catalyst. The other important factor in this formation was the energywhich in this case came from gamma radiation emitted by radioactive elements that were abundant in the early solar system. And the energy could not come from thermal heat, since this process occurs in icy environments, long before the asteroid was compacted or heated enough to have liquid water. This explains why we found amino acids both in asteroids that underwent a lot of water heating and in those that remained “drier” and colder. Life, it seems, is more stubborn than we thought and can begin to develop in the most hostile conditions of the vacuum of space. An increasingly complex menu. But we are not just talking about simple molecules, since analyzes of Bennu samples have identified a variety of compounds. Among these is tryptophan, which is an essential amino acid, much more structurally complex, and vital for terrestrial life. Besides, DNA and RNA components have been detectedin addition to ammonia and amines, surpassing in richness many samples of famous meteorites such as that of Murchison. Backlash to Panspermia. If amino acids can easily form in irradiated ice grains in the solar nebula—before the planets even formed—it means that these “ingredients” are spread throughout the solar system. The fact that Bennu, a B-type carbonaceous asteroid, is packed with these compounds reinforces the idea that Earth didn’t have to produce all the components of life itself. A constant shower of asteroids and meteorites during the late intense bombardment could having “sown” our planet with a pre-made deep space biological starter kit. That is why in the end looking at a grain of Bennu dust is looking at ourselves. Or, at least, to the chemical great-great-grandparents who made us here today.

Ten years ago, we were afraid of fast charging. The 10,000mAh batteries are going the same way

by

The world of smartphones is divided in two: a Chinese market betting on gigantic silicon-carbon and some “traditional” manufacturers who do not dare to take the leap. This weekend, the controversy was sparked by YouTuber Marques Brownlee, after publishing a video that has surpassed one million views in less than 24 hours. what has happened. “The problem with smartphone batteries”is the title of a video that has spread like wildfire among the community tech. In it, he explained some of the problems that silicon-carbon batteries supposedly suffer from, a technology that China is betting on to boost the capacity of its phones. above 10,000mAh. The problems. Silicon-carbon batteries are not a new technology, but they have been starting to be implemented in smartphones for just two years. During this time, there are several concerns on the table. Possible swelling due to the expansion of silicon: with each charge, a battery contracts and expands. Silicon can triple its volume, generating greater internal stresses in the battery. At the same time, there are fears that this expansion-contraction cycle could cause cracks and leaks in the battery. Need for reinforcement in battery compartment (such as small steel cages) to contain swelling. Long-term reliability not yet demonstrated in smartphones. Yes, but. Concerns about whether silicon-carbon batteries are safe or not are legitimate. Just as, back in the day, we were worried that a mobile phone with “fast” charging like the OnePlus 3 in 2016 (those times when Dash Charge was 30W) could explode. Today there are already mobile phones with 120W. The first commercial mobile phone to incorporate this type of battery was the Honor Magic 5 Pro in its Chinese version. No cases of the slightest problem have been reported to date in its more than two years of life. Manufacturers do not go crazy. Manufacturers are more than aware of the possible dangers that these types of batteries can have, and equip their phones with specific chips to control the charge in real time if excess heat is detected. Some brands, like Honor, go so far as to create microscopic tunnels in their batteries so that lithium ions can reduce chemical friction. Because yes, although carbon silicon batteries are called that, they are not made of pure silicon, they are a natural evolution of lithium batteries themselves. It’s not that easy. The next challenge after the introduction of silicon-carbon batteries has been to take advantage of their ability to store greater energy in a smaller size to achieve barbaric capacities: 7,000mAh, 7,500mAh, 10,000mAh. Energy densities notably higher than those that large manufacturers, such as Samsung, Apple and Google, currently mount in their high-end phones. Here an extra degree is added to the uncertainty: not only do we have more modern and not so tested batteries, but we also have capabilities that make their behavior even more unpredictable. Go deeper. The war for high-capacity batteries adds, apart from doubts about their reliability on the part of some manufacturers, logistical and economic challenges. They are more expensive batteries, and some manufacturers They are not taking them out of China yet. for that same reason. Added to this is that although the spec sheet tells us about milliamp hours, the main measure to determine the energy capacity of a battery is watt hours (Whr). Europe does not like batteries with more than 20 Whr, and they require longer and more expensive transport and authorization protocols. If the RAM crisis threatens to skyrocket the price of smartphones, thinking about incorporating significantly more expensive batteries does not seem like a viable plan to maintain the current margins of large manufacturers.

the minimum dose of exercise that science points to changing the health of those over 60 years of age

by

In the 1980s, gerontologist Robert N. Butler launched a phrase that has become in a mantra of modern medicine: “if exercise and physical activity could be packaged as a pill it would be the most widely prescribed and beneficial medication for the population.” Forty years later, science has stopped treating that phrase as a metaphor and turned it into a mathematical calculation. The ROI of the force. Until now, we knew that sport was healthy, but data on its direct clinical profitability were lacking. The GENUD research group, led by José Antonio Casajús, published in Experimental Gerontology at the end of 2025 one of the strongest evidence to date. The essay, carried out with 123 people over 80 years oldprescribed a treatment of three weekly supervised exercise sessions for six months. The clinical results were clear: improvements in functional capacity, reduction in frailty and increase in quality of life. But the data that has aroused the interest of health managers is economic. The conclusion here was that while the cost of the intervention was only 164 euros per person, The savings to the system exceeded 1,000 euros. The clinical squat. If exercise is the ideal drug, clinical evidence points to the squat being the most important active ingredient here. Many studies have precisely validated this movement, which can mean the world to some people, not as a gym exercise but as a diagnostic and treatment tool. Biomechanics is key. Why is the squat so important to medicine? First of all because it is an exercise that demands more on the hip extensorsvital for an elderly person to be able to get up from a chair or bed without help. But in addition, it also activates the quadriceps and plantar flexors more. At the metabolic and cardiovascular level, the impact is systemic. The venous compression that occurs during the squat increases venous return and cardiac output, acting as a natural pump that combats orthostatic hypotension. Even in post-stroke patients, fast squats have been shown to activate the injured rectus femoris, correcting asymmetries and improving postural control. How long. You don’t have to work hard, since a recent study showed that a program of just one minute a day, that is, about thirty seconds of squats and thirty seconds of push-ups, is enough. This is something that was seen with prescription by primary care physicians, improving physical performance in patients over 60 years of age with excellent adherence at 24 weeks. Anti-cancer effect. Beyond the effect on adults, important implications of physical exercises in pediatric cancer have also been seen. This was evidenced by Carmen Fiuza-Luces, from the Physical Exercise and Pediatric Cancer group, who directs the “La Aceleradora” project of the Unoentrecienmil Foundation. And contrary to the belief of having “absolute rest” when you have cancer, the evidence shows that exercise during treatment of pediatric solid tumors It achieves what no drug can. For example, it reduces the side effects of chemotherapy, protects the heart from the toxicity of the treatment or prevents atrophy in sick children. The problem is not the drug. The problem with prescribing exercise in consultation is lack of knowledge about the ‘dose’ that should be given. Just as a doctor does not say ‘take an antibiotic’ without a clear duration and frequency, the same thing happens with sports. You can’t say ‘do sports’. In these cases, exercise requires a dose in the form of frequency and duration, the intensity that must be personalized to each patient and, above all, monitoring with adaptation to the patient’s pathology. Looking for the front door. The Health and Sports Working Group of the Collegiate Medical Organization, coordinated by José Ramón Pallás, is pushing for integrate exercise into the National Health System as a therapy equivalent to drugs. The goal is for the “3 sets of 10 squats” recipe to be as official and binding as any blood pressure pill. In this way, science has done the numbers and all that remains is for the administration to make a move.

enter the United States in three years despite 100% tariffs

by

The Chinese automotive industry has set out to conquer the West, and Europe is too small for them. The great objective is to take a bite of the cake that is the United States, a risky bet if we take into account the tariff wall to the chinese electric car. And there is already a firm proposal: Geely is preparing its assault on the United States with two aces up its sleeve. Volvo… and Canada. The plan. Does a few daysthe Autoline Network media public an interview with Ash Sutcliffe. He is the head of global communications at Geely Holding Group, a Chinese giant that has its own brands such as Zeekr either Lynk&Cobut which also controls the Western Lotus, PolestarSmart and… Volvo. The interview was published within the framework of CES, the technology fair in Las Vegasand it was strange because, if there are 100% tariffs on Chinese electric cars, what was Geely doing there? The answer is simple: they are going to assault the US market. Sutcliffe commented that they are studying all the global markets in which they can expand and there is an internal question: when and where they will land in the United States. He did not share the roadmap, but did comment that they will have “an announcement on this in the next 24 to 36 months.” Trojan horse. There are many questions here and none of them were clearly answered in the interview. For example, what will happen to US tariffs or regulations on the Chinese software in cars? Sutcliffe simply said that Geely is an international group used to following the data protection and trade regulations of various countries, so they will do “whatever is necessary to follow those regulations when the time comes.” He gave the example of the European GDPRand although the interview does not connect the dots, the fact that they have taken advantage of such a framework to firmly assure that they will be in a market as complicated and hostile as the American one in the short term is a sign that they have given the matter more than one turn. Geely has an advantage here with Volvo, Polestar and Lotus. They are brands under their umbrella and already operate in the United States, but specifically, what Sutcliffe stated was that they want to land with Lynk & Co and Zeekr. North American Gate. There are two important questions. One is the tariff wall: 100% on electric vehicles from China. In practice, it would make it unfeasible for Geely to start selling cars because users would have to pay a premium that would make the brand simply unable to compete on price. But there are two safe passages. On the one hand, Geely build factories on American soil, a door opened by the Trump Administration if, with this, local employment is created. The Volvo factory South Carolina It would be an interesting and organic option for that local production. On the other hand, use brokers that export to US soil. There Canada can be the ace up your sleeve for the Chinese company. If they decide not to assemble the Zeekr/Lyn & Co in South Carolina, they can always import the vehicles from Canada and take them to the United States through that northern gate. Canada has recently moved from a 100% tariff Chinese electric vehicles at 6.1%. It is a very limited movement, since the initial quota will be 49,000 units per year. It’s a ridiculous number, but a start, and it could be a test bed for Geely to bring its 100% electric brands to the US from Canada. But hey, the United States is very aware of this and in fact, they have already saying that Canada “is going to regret it.” Feet of lead. With this management of brands like Volvo, Geely has an easier time than other Chinese competitors to get its foot in the US market, but there is an important nuance in all this. Geely has not said “in three years we will be selling thousands of cars,” but rather “in three years we will detail our plan to enter the United States.” However, although as we said, there is no specific public plan, it is evident that a statement like this implies that they are oiling the machinery to try do the same as in Europe. Now, taking into account the political climate and government maneuvers on issues such as trade or tariffs, things could change a lot in 36 months.

Creating a C compiler cost 2 million dollars and took 2 years. Claude Opus 4.6 did it in two weeks for $20,000

by

We are facing a technological inflection point. Uo in which software engineering, one of the most complex and demanding technical tasks in history, little by little It is becoming the “killer app” of AI. It is clear that generative AI models are not perfect, but we continue to see extraordinary evolution. The latest example? The C compiler that Claude Opus 4.6 programmed all by himself. what has happened. Nicholas Carlini, researcher at Anthropic, I counted yesterday how “I’ve been experimenting with a new way of monitoring language models that we’ve called “agent teams””. What it has done is ensure that several programming agents work in parallel using the recently released Claude Opus 4.6, and thanks to that it has developed something exceptional with 16 of these agents: a C code compiler. Hello CCC. At Anthropic they have called it Claude’s C Compiler (CCC), and they have published the code, completely generated by Opus 4.6, on GitHub. The project consists of 100,000 lines of Rust code that were generated in two weeks with an API cost of $20,000. And it works: with it they have compiled a functional Linux 6.9 kernel on x86, ARM and RISC-V. Before it was (at least) two million dollars and two years. What this experiment has achieved is to demonstrate how software development can be much cheaper and faster thanks to the use of these agents. Although there is no readily available data on how much time and money compilers cost in the past, the size of these products was enormous, as is the case with Microsoft Visual C++For example. It is difficult to know how much it cost, but it is estimated that it involved 15-20 people working for five years. That’s a lot of man hours and a lot of money to develop and polish that compiler. The estimate of two years and two million dollars may in fact be overly optimistic. another example. Historically, building a C compiler from scratch was considered one of the pinnacles of systems engineering. Not only was in-depth knowledge of processor architecture required, but thousands of man-hours were required to manage optimization and machine code generation. In the 90s the company Cygnus Solutions (clue in compiler development gcc) came to invest more than 250 million in a decade to maintain and port build tools. The real cost was not just in the final lines of code, but in countless hours analyzing CPU and memory patterns to make the resulting binary efficient. Far from perfect, but… Carlini himself explained in the post that this compiler had serious limitations and for example “it does not have a 16-bit x86 compiler which is essential to start Linux outside of “real mode”, and it does not have its own assembler nor its linker“. It is probably far from mature compilers, but even so the achievement remains exceptional and points to that future in which even very complex developments can be supported with AI. They will be expensive, no doubt, but their total development will probably be a fraction of what they cost a few years ago. Cursor already demonstrated it. Before Anthropic launched its AI-programmed compiler, Cursor completed a similar project, combining GPT-5.2 agents into its development platform to create a working browser in a week. In total the AI ​​programmed three million (!) lines of code in Rust, and although it was again far from being perfect or competing with Chrome, it demonstrated the current capacity of these agentic programming systems. Turning point (especially for Anthropic). For the SemiAnalysis experts Claude Code, current leading exponent of this new era of AI-driven programming, is a paradigm shift: “We believe that Claude Code is the turning point for AI agents and is a glimpse into the future of how AI will work.” This prestigious newsletter predicts an exceptional 2026 for Anthropic, and so much so that they believe it will “dramatically surpass OpenAI.” You ask, the AI ​​programs. If you have tried the vibe codingI’m sure you agree with me: AI allows you to do things you would never have dreamed of. What I did a few weeks ago with Immich made it clear to me, and I continue experimenting with AI and programming “custom” things that solve real problems and needs for me. Yes, for now they are for me and therefore they are not large and complex systems that need to be put into production as happens in professional environments, but I am clear that this is being done little by little and more will be done. In fact, both OpenAI and Anthropic have stood out how in the development of their latest models part of the work has been done, paradoxically, by those same models, which have fed back to each other. And the result is in production and used by millions of people. Something is changing. And it’s something big.

In Tokyo there is a bookstore with only one book in the catalog. It has been open for ten years and works

by

In an alley in the Ginza district of Tokyo, a small white-painted room houses what could be considered the most radical bookstore in the world. Morioka Shotenopened in May 2015 by Yoshiyuki Morioka, reverses the commercial logic of the book: while the Japanese publishing industry produces approximately 80,000 new titles each yearthis establishment only sells one, which is renewed every week. It is not performance. Morioka Shoten It is a business that works, selling multiple copies of a single work for six consecutive days. The interior is unusually bare for a bookstore (concrete walls, a piece of furniture used as a counter, a cable telephone) and serves as a canvas for displays inspired by the current book. It is a bit the absolute opposite of Amazon: from infinite offer to minimalism in choice. How it works. Each title remains on display for exactly six days, from Tuesday to Sunday, accompanied by artistic installations, objects or photographs related to its content. The space functions simultaneously as a gallery and a point of sale. The location of the project reinforces this symbolic dimension: the Suzuki Buildingbuilt in 1929 and protected as historic architecture, housed between the 1930s and the end of World War II the offices of Nippon Kobo, the publisher that produced the magazine ‘Nippon’, which many consider foundational for the modern Japanese publishing industry. The context. The opening of Morioka Shoten in 2015 comes at a critical time for the industry. Two decades earlier, in 1995, Amazon had begun operations, and the domino effect was inevitable: American independent bookstores went from more than 7,000 stores in 1994 to just 1,651 in 2009, a reduction of 76%. The physical bookstore model seemed obsolete given the speed of the Internet and recommendation algorithms. Morioka Shoten proposed just the opposite: concentration, deliberate scarcity and time to focus on a single work. The philosophy of issatsu, isshitsu. The Japanese expression issatsu, isshitsu It means “a room, a book.” For eight years, Yoshiyuki Morioka worked as an employee in second-hand bookstores in the Kanda neighborhood, a traditional bibliophile district in Tokyo. He later opened his own independent bookstore in Kayabacho, where he organized author presentations that multiplied sales. The question that it was done was: why maintain hundreds of works if the optimal experience was produced with just one? The Takram design studio developed the store’s visual identity based on a sketch by Morioka himself: a rhombus that condenses the double metaphor of the project, simultaneously representing an open book and a single room. The resurgence of indie. The proposal is part of a broader recovery of independent book trade. In 2015, a curious phenomenon occurred in the United States: American indie bookstores. They began to multiplyup to 49%. The study cited factors such as the feeling of community, the work of booksellers as curators and the capacity of bookstores as meeting points. The pandemic accelerated the trend: since 2020 The sector grew by 70%, in 2024, 323 new stores were inaugurated and in 2025, more than a hundred additional stores were opened in the first months of the year alone. Quality over quantity. The commercial results of the experiment confirm the viability of the model. Morioka Shoten has sold more than 2,000 works since its inauguration. The weekly catalog has ranged from comics by Tove Jansson to botanical photographs by Karl Blossfeldt, novels by Mimei Ogawa and short stories by Hans Christian Andersen, spanning fiction, non-fiction, manga and illustrated books. In an era that offers immediate access to millions of titles, abundance generates paralysis when it comes to decisions. From that point of view, Morioka’s radical limitation does not restrict, but liberates. In Xataka | The 24 most beautiful bookstores in the world
