If you take these drugs, heat may be more dangerous than you think

by

We all know that, when it is very hot, we should drink a lot of water, avoid going outside during the hours of the sun and cool rooms properly. We also know that the copious meals They are not a good idea and may not be the best occasions to eat spicy food. But what we are not always warned about is that there are drugs that increase the risk of getting sick due to heat, so we must take extreme precautions if we take them. It is not about leaving them, but about being aware of the risks that increase to take the necessary measures. A very long list. The list of drugs that increase the risk of heat-related illnesses it’s very long. Some examples are certain hypertensives, beta-blockers, antiarrhythmics or non-steroidal anti-inflammatory drugs (NSAIDs). It can also occur with opioids, benzodiazepines, antidepressants, antiepileptics, antidiabetics, laxatives, anticoagulants or antihistamines. Does this mean that all these groups of drugs quickly increase the risk of heat stroke? Not necessarily. To begin with, they are not all medications in each group and, furthermore, they do not always affect health for the same reasons. The mechanisms. The main mechanism by which these risks increase is dehydration. For example, some antihypertensive drugs are diuretics. This means that they increase urination, making it easier for dehydration to occur; which, in itself, is more common in a heat wave situation. Symptoms related to impaired kidney function may also occur. When we become dehydrated, the amount of water in our blood decreases, so kidney function can be affected. Therefore, care should be taken with drugs that already affect hydration, as they can increase the risk of kidney failure. On the other hand, there are drugs that affect thermoregulation. If the body is not able to regulate temperature, it is easier to suffer heat stroke. Others affect alertness, so those who consume them may not notice the symptoms of heat stroke. Happens with some benzodiazepines. And something similar happens with drugs that alter the perception of thirst. Finally, there are medications that cause hyperthermia, so that the body temperature rises too high. Sometimes it is bidirectional. Some of these mechanisms can cause the medications themselves to cause more side effects. For example, some NSAID drugs are eliminated through urine, with prior intervention of the kidney, but if it does not function properly due to dehydration, they accumulate, potentially causing toxicity. Furthermore, their way of reducing pain is by inhibiting the synthesis of prostaglandins, which are necessary for renal perfusion, so, with a kidney that does not already function very well, they can be harmful. It is precisely for this reason that, in situations of heat waves extreme, Doctors are advised not to prescribe certain NSAIDs. More cases of increased toxicity. In general, heat can increase the toxicity of some drugs in several ways. For example, dehydration can alter the concentrations of certain drugs in the blood. The difference is usually minimal. However, there are medications, such as lithium, in which the difference in concentration between the therapeutic effect and toxicity is minimal. That is why care must be taken. You should also be careful with cutaneous medications, such as patches, or subcutaneous medications, such as insulin, since if it is very hot they may be absorbed more quickly. People at higher risk. All of this does not affect all people equally. Generally, the risk is greater for older people, patients who live in isolation or with poorly air-conditioned housing and, especially, people who take several medications at the same time. Hydration is essential if you are taking certain medications What should we do? As patients, we must mainly ensure that drugs are stored at the temperature indicated on the package insert. Beyond that, it is usually the doctor who has to pay attention to each patient’s history and determine whether, in a given climatic situation, there may be risks with the drugs taken. In any case, if we have doubts, we can always read the leaflet and/or consult our family doctor about the medications we take. It is important to emphasize that these types of situations are usually extreme. It must be very hot and the person must be vulnerable for some reason. Furthermore, many times these are situations that can be prevented. If the problem is due to the risk of dehydration, the patient is instructed to drink much more water. The same if the problem is that the perception of thirst decreases. Each case is different, so it is important to study them individually, taking into account that they are extreme situations, but that they must be considered if necessary.

New vivo X Fold6, features, price and technical sheet

by

For years we have seen how vivo built, generation after generation, an increasingly ambitious family of folding products. First came the XFoldthen new iterations, improvements in cameras, more refined screens and proposals that looked directly at the highest range. But there was one detail that, from Spain, always left the same feeling: those cell phones passed before our eyes without officially landing here. Now that dynamic changes with the vivo X Fold6a foldable that comes with a very ambitious technical sheet and opens an unprecedented stage for the brand in the country. The X Fold6 arrives with a technical sheet that makes it clear where Vivo wants to place it: in the high range of this format. Everything points to a device designed for photography, work and content consumption, not just to show off its format. Technical sheet of the new vivo X Fold6 ivo X Fold6 Dimensions and weight Unfolded: 157.16 x 145.66 mmFolded: 157.16 x 74.26 mmThickness: 4.8 mm unfolded / 9.9 mm folded in Blue; 4.4 mm unfolded / 9.4 mm folded in black and white colorsWeight: 235 g in Blue color; 228 g in black and white colors Indoor screen 8.02 inch AMOLEDResolution 2,504 x 2,312 pixelsFormat 4:3.6991.99% screen to body ratioUp to 120Hz10.7 million colorsHDR Outdoor screen 6.51 inch AMOLEDResolution 2,528 x 1,120 pixels20.31:9 format92.65% screen to body ratioUp to 120Hz10.7 million colorsHDR processor MediaTek Dimensity 9500 Eight core CPU1 x 4.21GHz + 3 x 3.5GHz + 4 x 2.7GHz3nm processARM G1-Ultra GPU memory 12GB/16GB LPDDR5X Ultra Storage 256GB / 512GB / 1TB UFS 4.1 Battery Dual battery in parallelTypical equivalent capacity: 7,000 mAhEquivalent nominal capacity: 6,760 mAhFast wired charging up to 80WWireless charging up to 40WOTG reverse charging rear cameras Main: 200 MP ZEISS, f/1.68, OISTelephoto lens: 50 MP ZEISS APO, f/2.57, OIS, digital zoom up to 100xUltra wide angle: 50 MP ZEISS, f/2.05Autofocus on the three rear camerasVideo up to 8K Front cameras 20 MP on interior screen + 20 MP on exterior screenf/2.4Stabilized video Operating system OriginOS 6 Fold based on Android 16 Connectivity 5G with dual SIM and dual nano SIMWi-Fi 7Bluetooth 5.4NFCGPS, BeiDou, GLONASS, Galileo, QZSS and NavICUSB-C 3.2 Gen 2DisplayPort output Others Side capacitive fingerprint readerfacial recognitioninfrared sensorLinear motor on X axisAtmospheric pressure sensorHall sensorlaser focusCompatible with USB-C digital headphones Price China:12GB + 256GB: 7,999 yuan12GB + 512GB: 8,999 yuan16GB + 512GB: 9,999 yuan16GB + 1TB: 10,999 yuan A live folding, finally, for Spain The photographic section is one of the great arguments of the vivo X Fold6, and not only because of the 200 MP figure. According to vivo, the ZEISS main camera works with a Samsung HPB sensor and five very low reflection lens elements, while the 50 MP ZEISS APO telephoto camera adds a 3x periscopic structureCIPA 4.5 stabilization, ZEISS hyperzoom up to 100x and telemacro up to 20x. The third piece is a 50 MP ZEISS ultra wide angle, designed for wide scenes. Added to this is the ZEISS T coating and the vivo BlueImage V3+ chip, which should help with clarity, stability and efficiency of photo processing, especially in complex lighting scenes. The most unique piece of the system is the ZEISS Vivo 200mm Gen 2 Equivalent Telephoto Extender, a 2.35x optical accessory designed to take the foldable camera further for distant scenes, concerts, live events or travel. vivo speaks 96 mm in length and 153 g in weight, with a Keplerian optical structure of 2 groups and 15 high transmittance glass elements. The press release does not indicate that it is included in the box nor does it yet detail how it will be sold in Europe along with the X Fold6, so that point is pending for the European launch. For reference, vivo now sells the X300 Pro Telephoto Extender Kit in Europe for 349 eurosreduced from 399 euros, and also offers it associated with photographic kits of the X300 family. Autonomy is another point where I want to distance myself. The X Fold6 incorporates a battery 7,000 mAh BlueVolt In the versions presented, a particularly striking figure in a foldable, where the internal space is usually more conditioned by the hinge and the double screen. This is supported by a third-generation semi-solid battery and fifth-generation silicon anode technology, designed to increase energy density. Charging is completed with 80W FlashCharge wired fast charging, 40W wireless fast charging, and reverse charging to power other devices. In performance, vivo does not resort to a secondary platform, but to the Dimension 9500 improved, a version worked together with MediaTek for large screens, multitasking and artificial intelligence on the device itself. We are talking about MediaTek’s most powerful SoC and a direct rival to Qualcomm in the premium range, although not the most powerful Android processor in absolute terms, because that place corresponds to the Snapdragon 8 Elite Gen 5. It is pure high-end, the same league as mobiles like the Oppo Find X9 Pro and the vivo X300 Pro. On that basis, Vivo promises 111% more peak performance on the NPU and 56% less peak consumption on that unit compared to the previous generation. The other big half of the experience is on the screens. The vivo X Fold6 incorporates a 8.02 inch inner and a 6.51-inch exterior, both 120 Hz LTPO, a refresh rate that should help make scrolling, animations, and switching between apps feel more fluid. The key, however, is how I try to take advantage of that large canvas with Atomic Workbench. According to the company, the ‘series’ mode allows you to use up to five applications in the foreground and four in the background, while the ‘parallel’ mode places up to four active apps side by side to compare information and work without constantly switching applications. vivo also tries to reinforce the idea of ​​premium folding from design and resistance. The X Fold6 will be available in China in blue, white and black: the blue model uses glass with a frosted finish inspired by the large blue holes of the … Read more

Germany and France need to imitate Spain to survive the heat

by

Melting roads, bursting train tracks and firefighters watering bridges. While in Spain we deal with the heat by lowering the blinds, in Europe we are looking for solutions to try to survive a heat wave that has blown up the most basic mobility infrastructures. “You should look at Japan”. “You should look at how rail transport works in Japan. There it also reaches 40 degrees in summer and the trains are not constantly cancelled” or “it happened 20 years ago, the air conditioning has failed. (…) the problem has existed for a long time and nothing is done.” There are two comments that reported in one of the local media in Bavaria (Germany). In the text, one of the reporters explains that “the passengers were completely sweaty and accepted the situation with resignation” when it was reported that the regional train in which they were traveling had broken down its air conditioning. With 35 degrees outside and more than 40 degrees inside, the problem was obvious. So evident that Marco Kragulji, spokesman for the German passenger association “Pro Bahn”pointed out that, quite simply, “Germany has problems with its trains when the heat comes.” Click on the image to go to the original tweet Germany, Belgium… German trains with broken air conditioning have been just one of the problems encountered by rail traffic in a burning central Europe. And in the country too Tram tracks have been broken in the city of Essen because of the heat. It is by no means the only case. In Brussels the tram tracks have also jumpedtearing up the asphalt and completely stopping traffic. The causes are simple: train tracks are designed to withstand temperatures typical of countries that used to be colder. Heat expands the materials and ends up splitting them.destroying the infrastructure. Click on the image to go to the original tweet “We recommend that you do not take the train”. In addition to broken tracks, SNCF (the French Renfe) has recommended that “vulnerable users” don’t take the train. And the problems with the air conditioning are constant and have even been the main reason why Dozens of trains were suspended last week. The problem is that the heat is being so extreme that it is putting the trains that have been in operation for more than 20 years to the test. Those trains were designed in a context that, except for the heat wave of 2003, does not exist today. And now the Spanish trains are given as an example, much better armed to withstand extreme temperatures. looking south. In the German media they use the Spanish and Italian infrastructure as an example. They claim that Deutsche Bahn (in this case, the German Renfe) designed the rails for the train to withstand temperatures that are now considered too low. And the problem, they point out in this medium specialized in engineeringit is not the ambient temperature, it is that the tracks, due to the concentrated heat and the passage of the trains, reach much higher temperatures that, now, break the tracks. Generalists focus on the fact that Spanish and Italian roads use colors that reflect the sun to reduce the temperature. But also They praise the air conditioning systems of Spanish trains that are more powerful and with more recurring departures within the cars. Both France and Germany point out, however, that the latest generation trains that are arriving on their tracks already use powerful air conditioning systems to face these new situations. And they are even adding batteries to ensure that the air conditioning remains active in case of a breakdown. Photo | Linus Follert and windy In Xataka | Some roads are literally melting.

Millions of men wake up every morning with an erection. This is excellent news for them.

by

There is a deep-rooted popular belief that associates the presence of morning erections exclusively to testosterone levels and the “virility” that man has. But recently it is being seen that this is something that can be an indicator of having good cardiovascular health, although logically not having them does not categorically mean that there is a disease in the heart or arteries. Its foundation. Here the scientific literature has a very important position, since, although there is a real basis to point out that the absence of these erections is an important symptom, it does not function as a ‘yes or no’, but is a continuous and complex marker. In this way, if we analyze the evidence from the most powerful population studies of recent decades, we discover that morning erections speak much less about our hormones and much more about our arteries. A thermometer of cardiovascular health. To understand why an erection matters at a systemic level, we must remember that we are dealing with a fundamentally vascular phenomenon. The arteries of the penis in this case are much narrower than the coronary arteries, and that is why, if we have a process of atherosclerosis or endothelial dysfunction that is beginning in the body, the smaller arteries will be the first to fail. This is why erectile dysfunction is a very important predictor for cardiologists and urologists to know what the inside of the arteries may be like without having to do any extra tests. Risk in escalation. A landmark study published in PLOS Medicine in 2013 continued to more than 95,000 men and showed that cardiovascular risk is increasing. In this way, it was seen that men with severe erectile dysfunction had almost double the risk of general mortality compared to those who did not suffer from it. This adds to a second study published in Circulation with almost 93,000 men which confirmed that erectile dysfunction increases the risk of total cardiovascular events by 44% and the risk of acute myocardial infarction by 62%. Testosterone. This is where popular culture collides with the data provided by scientific evidence. It is true that testosterone reaches its maximum peak in the morning and it is logical to think that this enhances the morning erections that men have, but a 2019 observational study carried out on 761 men showed that those who maintained their nocturnal erections had, on average, slightly higher total testosterone and lower libido. But testosterone does not explain the risk of suffering from serious disease in our arteries. Here the European Male Aging Study followed about 1,660 men for more than 12 years and analyzed different specific symptoms: erectile dysfunction, low libido and loss of morning erections. And here they saw that having poor erections in the morning increased the risk of mortality by 28%. It’s not testosterone. The key to this study is that, when adjusting the results based on the patients’ testosterone levels, the risk of mortality remained exactly the same. This means that it does not matter whether you have more or less testosterone, because what is truly important here is to have ‘clean’ arteries that allow blood to be carried to the penis without any type of obstacle. There is no need to obsess. We must not fall into the trap of stating that the absence of morning erections is the same as having a major underlying disease. What we must keep in mind is that we are faced with one more risk factor or symptom that is added to many others in a complex puzzle that must occur for a specific disease to occur, and that is why this is something that is left in the hands of medical specialists to determine what may be happening inside the arteries.

A cement company stopped sending its personnel to inspect dangerous areas. Your new inspector is a robot dog

by

Even though the conversation revolves around humanoid robotics Lately, this sector has had much more traction in the industry for decades, driving a good part of the current processes and assembly lines. In this regard, a Swiss cement plant has wanted to take advantage of robotics in a somewhat peculiar way: it has been using a quadruped robot to monitor your facilities every night. Below these lines we tell you all the details. The problem that had to be solved. Vigier Ciment has been producing cement in the hills of the Swiss Jura, south of Biel, for a century and a half, generating approximately a fifth of all cement in the country. Its plant houses more than 1,000 machines spread across several buildings and floors, connected by metal stairs of up to 16 sections, areas with temperatures that reach 50 degrees, constant dust and the occasional presence of ammonia near the unloading docks. The maintenance of all this fell to operators who toured the facilities on foot filling out paper records. Over time, continued exposure to these conditions generates what the plant workers themselves call “operational blindness.” You stop seeing what is in front of you because you have already seen it too many times, according to collect Techeblog. The guard dog. Just like account The medium, in November 2024 the Swiss robotics company ANYbotics began talks with Vigier Ciment to deploy its ANYmal quadruped robot at the plant. The robot arrived on January 6, 2025 and before the end of the first month it was already carrying out night patrols completely autonomously. ANYmal is similar in size to a large dog and weighs more than 50 kilos. It does not need human supervision, and its managers say it climbs stairs, avoids obstacles, navigates narrow hallways and accesses areas that previously required considerable effort on the part of staff. What exactly does it do in every round. Every night, even on weekends, ANYmal goes through more than 450 inspection points predefined elements distributed in three mills and six levels. To do this, it has several detection systems, including a visual camera that identifies cracks, oil leaks or corrosion; a thermal camera that measures the temperature of critical components such as bearings, motors and gears; a gas sensor that monitors ammonia levels; and an acoustic camera capable of locating compressed air leaks or filter failures at distances of up to 50 meters. According to point In the middle, all that information is automatically dumped into a software platform called Data Navigator, which analyzes the data collected overnight, compares it to the facility’s history, and generates a daily report for the maintenance team. What he has found along the way. In sixteen months of operation, ANYmal has already completed more than 33,000 inspections without recording any technical failures. According to ANYbotics, the most relevant findings have had a direct impact on plant operations. The middle share In addition, the robot detected a crack in the base of a shredder the size of a large kitchen table. The oil had been leaking for some time and no one had reported it on the usual rounds. The repair was completed the next day. Had it collapsed, the plant would have lost more than a week of production, with estimated losses of more than $630,000, according to the company’s own figures. In another case, thermal monitoring detected a bearing reaching 140 degrees Celsius, allowing a $30,000 eight-hour repair to be scheduled rather than facing a much more costly emergency failure. The robot also detected levels of ammonia exposure at unloading docks that had not been measured until then, and located air leaks in filtration systems installed 50 meters high. Industrial maintenance. The plant’s traditional fixed sensors only covered about 200 elements, mainly on the clinker side (the main component of cement). The robot expands that coverage substantially and accesses areas that static sensors cannot reach. At the same time, it removes operators from the most dangerous environments without reducing the frequency or quality of inspections.

The prompt engineering fashion is over. Now what is important is loop engineering

by

In the last three years we have seen how if you wanted to be an advanced user of AI, you had to become a prompt engineer: The way you ask the AI ​​things was vital to achieving the best results. That idea is now becoming obsolete, because an even more promising technique is beginning to emerge to make the most of chatbos. From prompts to loops. The new paradigm that has become a viral trend among developers is that of the so-called “loop engineering” (“loop engineering”) that assumes something important: that the AI ​​is going to hallucinate or make mistakes. And with this method a feedback system is implemented: a subagent generates a response, another audits it and looks for errors, and then the system automatically reruns the process until the result meets the quality standards specified by the user. AI Gurus Recommend Loops. Boris Cherny, creator of Claude Code, explained in a recent talk how he no longer writes prompts in Claude Code, but instead writes loops. “Loops do the job. My job is to write loops.” Peter Steinberger, creator of OpenClaw, agreed and commented on X that “you should not write prompts for scheduling agents. You should design loops that create prompts for your agents.” Addy Osmani, head of Google Cloud, exactly stated same idea: “loop engineering is replacing you as the person who creates the prompts for the agent. You design the system that does that instead of you.” Implacable cycle. This type of approach is what has managed to succeed in AI agents such as Claude Code or OpenClaw. The model can run code in a safe environment, test it, read error messages if they exist, and then fix those failures to get back to the beginning. AI already “reasoned”, but now it is capable of self-assessment and self-correction autonomously and independently. Steinberger put a clear example how to design one of these loops. Goodbye to the chat window. The technique is being very popular among developers, but at the same time it poses a potential disappearance of the traditional chatbot in the browser window. The value was previously in chat with AI and experiment with promptsbut now the idea is to propose automated workflows. The user only sees the initial problem and the final solution, there are no constant questions and doubts unless the user wants to refine after that final solution. Be careful with costs. The problem with this idea is that by designing a loop one can launch several subagents that work in parallel. This implies an expenditure of tokens that can be considerable, which threatens to be very expensive. The recommendation, of course, is to use subagents and loops when it makes sense. Another stage in the evolution of AI. The passing of the prompts to loops poses a new phase in the evolution of AI. ChatGPT amazed us by creating quick poems, but the process was inefficient because talking is not always the optimal route to achieve the desired result. The profession of ‘prompt engineer’ could therefore be threatened after that initial phase in which knowing how to talk to the AI ​​was the important thing. Now the powerful thing is knowing how to design those loops that end up doing everything for the user. Image | Compagnons In Xataka | Claude Code is being the big favorite among programmers.

There is a flying saucer sailing down a river in Vietnam. A YouTuber built it in his yard with sand, scrap metal and fiberglass

by

Some time ago Thanh Cheaka ‘Mr. Ho’, a youtuber Vietnamese with more than 1.4 million subscribers, had a crazy idea: to sail the rivers of his country with a flying template. Literally. For anyone else, an idea like that would have remained just that: a crazy dream. It took Mr. Ho to get to work and build a kind of boat made with little more than sand, fiberglass and the propulsion system of a jet ski. However, the most curious thing is not the result, but the process. Mr. Ho Thanh Che. To ‘Mr. He’s up for challenges. Especially those that involve assembling (or repairing) motorized devices with materials that anyone could find without too many complications. In recent years this has led it to manufacture your own boatstart a car that had been rotting for years in the middle of the jungle, ride a vehicle with materials taken from a landfill or designing a jet ski shaped like a giant spider. A water UFO. As if all of the above were not enough, some time ago Mr. Ho decided to go one step further and create a flying saucer capable of crossing the rivers of Vietnam at full speed. It sounds crazy (and it is), but that’s just what the youtuber shows in a video of just one hour in which he documents the entire process: from the moment he imagines the design (in his dreams) to the moment he takes his ‘flying saucer boat’ into the water. The challenge is so fascinating that the video has more than 30 million views. And that’s just on Mr. Ho’s personal account. The piece has been shared on other channels in which it accumulates thousands and thousands of views. Nothing surprising if we take into account that the youtuber It does not have a large workshop, nor access to exclusive parts. In his projects (including the UFO project) he uses the resources he has at hand, even if sometimes they are little more than scrap metal. playing with sand. The most curious thing about the project is how it starts. For someone with access to industrial molds or modern milling machines, manufacturing the hull of the flying saucer wouldn’t have much substance. Mr. Ho had to settle for a solution more rudimentary: He traced the silhouette of the saucer on the ground of a patio, piled sand on top, and then shaped the mound with the help of a rotating arm made from scrap metal. The goal: create a symmetrical dome. That kind of sand shell served as his starting point. Then the youtuber He poured cement, consolidated the shape and used it as a framework to make the two halves of the hull (aka space saucer) with fiberglass. By hand. Step by step. With the same patience that would be used to make a piece of craftsmanship. With the helmet ready, he opened several hexagonal-shaped holes. Under way. To move the ‘flying saucer boat’, Mr. Ho opted for a solution similar to that of jet skis: a hydrojet systemjet propulsion, which is powered by an engine allows a turbine to absorb water and then expel it at high pressure. Among other things, this avoids external propellers. So that his particular flying saucer could be handled more easily, the youtuber used a deflector attached to a cable that in turn directs the water jet. The video shows how that solution allows you to direct the jet and make tight turns. As it is housed in a hollow cavity in the inner hull, the engine does not break the spaceship aesthetic that its creator wanted to give it. A carpeted flying saucer. On this occasion Mr. Ho was not satisfied with creating a boat in the shape of a flying jig. He also wanted to take care of the details of the design. Both external and internal. On the outside it included LEDs, solar panels and a dark gray color that gives the result an aesthetic that is partly (partly) reminiscent of the B-2 bombers of the USAF. Inside, Ho opted for the same philosophy: taking care of the details, including carpet, soundproofing and tinted acrylic windows. In a nod to his main platform as a creator, he gave the ship a yoke-type steering wheel with the YouTube logo. It is difficult to determine whether the pilot is traveling comfortably, but the video of the maiden voyage It shows that at least the ship is stable and fast.

so you can reserve yours

by

On the Internet, we may have already been late for our username more than once. In one network it was busy, in another we had to add numbers and in some we ended up accepting a version that never convinced us. WhatsApp now opens a different window: reserve an identifier before it can be used later this year. Until now, the phone number has been the centerpiece of identity on WhatsApp: it is used to create the account and, in practice, also so that others can find us. What changes with the usernames is that second part, because WhatsApp will allow, when the function is active, for someone to contact us for the first time without us having to give them our number. The company itself proposes it as a privacy measure for everyday situations, from a group with people we don’t know to a specific conversation with someone we just met. ANDl number will still be required to open the accountbut it will no longer always have to be the letter of introduction. How to reserve your username on WhatsApp To reserve it, the path indicated by WhatsApp is simple: you must have the most recent version of the application installed and enter Settings > Account > Username. From there, when the reservation is available, we can choose the name we want to use later, once the function is generally activated. The official WhatsApp account on X says that reservations will begin this week | Click to see the original publication The company led by Mark Zuckerberg explains that the deployment will be gradual during the coming months and that will notify within WhatsApp when the usernames are available in each country. It should be noted that usernames may be between 3 and 40 characters, and the company will allow you to change the username or deactivate the function at any time. In our case, at the time of writing this article, we have tried from Spain and the option still does not appear. This fits perfectly with what the company announced, which talks about a gradual implementation over the coming months and notifications within the app when the function is available in each country. So if you don’t see it yet, it doesn’t necessarily mean you’re doing something wrong. Early booking has a simple explanation: in a service of this scale, many names can coincide and the most obvious ones can soon be disputed. WhatsApp summarizes it with a piece of information that appears in Meta’s financial results for the first quarter of 2025: The application exceeds 3 billion monthly active users. There is an important difference compared to how usernames work on some platforms: WhatsApp will not allow you to search for profiles as if we were on a social network. According to the company, there will be no directory or suggestions, and people will have to know the exact username to get in touch for the first time. Additionally, WhatsApp will add an optional username key to reinforce that initial filter. That is, the objective is not to gain visibility, but to provide a more private and controlled form of contact than the telephone number. There is another important piece to this reservation: not all names are put into play in the same way. WhatsApp explains that creators, small businesses and organizations will be able to claim their existing Instagram or Facebook name, something designed for those who need a recognizable and constant presence. On the other hand, the company has already reserved names of public figures to avoid opportunistic appropriations.

Spanish oil is changing radically and we are only now beginning to realize it

by

There was a time when some olive oil jugs came with an anti-theft alarm. Those were the years in which the liter was close to ten euros and analysts wondered if the EVOO culture was dead. Traditional producers were drowning between meager production and falling demand. That was all two years ago. Now things have changed. Now prices are at rock bottom and, as a consequence, more than 75% of the Spanish olive grove, according to the association of olive municipalities, already produces below costs. The data is accurate; the producers are still drowning; The panorama is desolate. However, none of this means what it seems. The 75% figure. The assembly of the AEMO (Spanish Association of Municipalities of the Olivo) met in Adamuz and advanced its cost study for 2026. According to its calculations, the price at origin is 3.51 euros and that means that More than 75% of the olive growing area is already producing at a loss or at the limit of profitability. It makes sense. The AEMO does a more subtle job than we usually see and elaborates not “a cost” but sevenone for each cultivation system. As soon as we start to think in those terms, the olive grove stops being a ‘sea of ​​olive trees’ and becomes a very complex agro-industrial system. To give us an idea, the costs of the traditional mountain olive grove are about 5.31 euros per kilo, while the irrigated hedge is 3.07. Thus, with the average price of 3.51 euros, the hedge gains money and the traditional mountain hedge loses almost two euros. The hunger games. To be fair, we have to recognize that the AEMO is ‘part’ in this discussion (it defends the traditional olive grove) and, furthermore, has not yet published the entire report. However, the figures fit with what we already knew: no matter what happens in the olive oil market, the result is always the same: the irrigated olive grove wins. This is so clear that there is a whole mad race for make all hectares irrigated that they can (at all costs at a social, economic and environmental level). The current situation… It has to do, above all, with excess oil: after some bad seasons, we have gone from around 666,000 tons in 2022/23 to around 1.4 million in the last two campaigns. As there is a type of olive tree that can continue to be profitable at very low prices, there are no real incentives to contain the supply and that exposes a good part of the industry to having to assume the losses to stay alive for another season. And why should we care about olive farmers now? In our country (and without going into speculation about how good or bad the sector is), the olive grove has a key role in the economic, labor and industrial structure of Empty Spain. It is a discreet and underappreciated role; but that undoubtedly forms part of the basal structure of a good part of the country. It is not an accident that the association that is moving this is of municipalities: the traditional olive grove is an issue of great territorial importance. Because we must not be fooled. We talk about surface, not production. The irrigated olive grove is much more productive and is increasingly important. What we are seeing is a change of model within the sector and, linked to that, we are beginning to see the consequences it will have in the medium term. Spiler: they will not be good for most of olive-growing Spain.
