cost

It’s been going up for days and we already have queues at the low cost

by

The conflict between the US, Israel and Iranand its consequent tension in the rest of the Middle East countries has been generating uncertainty in the energy markets for weeks. The barrel of Brent has risen nearly 30% so far this year, 8% this Monday alone. Goldman Sachs has revised its forecasts upwards and prices at Spanish gas stations have already chained five consecutive increases. In Spain, we are preparing for a gradual rise in price of gasoline. So much so that already long queues have been detected at service stations in some parts of the country. One of the most striking examples has been this Costco in Sevillewhere his gas station is flooded by a flood of cars. A scenario that recalls, with important nuances, what happened in 2022 with the Russian invasion of Ukraine. what’s happening. At the end of 2025, the price of fuel was giving some relief to drivers throughout Spain. Just like they count From El Motor, 95 gasoline had fallen by about 3.5% and diesel by more than 5% since November. However, this trend has ended in the most devastating and undesirable way possible: with another war. Image: Dieselogasolina.com (data extracted from the Ministry of Ecological Transition) According to the data from the Dieselogasolina web portal extracted from the Ministry of Ecological Transitionthe average price of 95 gasoline in the Peninsula and the Balearic Islands stands at €1,557/l this March 4, compared to €1,531/l the previous day. Diesel has gone from €1,492/l to €1,539/l in the same day. Five consecutive increases that coincide with the escalation of war in the Middle East. A bottleneck. As you’ve probably heard or read, most of the problem has to do with the Strait of Hormuz, which has stopped its traffic due to this escalation of war and which is where approximately 20% of the world’s production of crude oil and liquefied natural gas transits. The barrel of Brent reached close to $80 in the first days of March, after accumulating nearly a 30% increase so far this year, as share The Vanguard. Europe does not import Iranian crude oil directly (90% of Iran’s exports go to China), but the blockade of the Strait affects the global reference price, and that price does reach European suppliers. What the experts say. Goldman Sachs this week revised upwards its forecast for the second quarter of 2026, in which it expects Brent stands on average at 76 dollars per barrelten dollars more than his previous estimate. The bank warns that risks are “significantly skewed to the upside,” as share the WSJ. And the bank points out that if exports through the Strait of Hormuz remained restricted for five more weeks, Brent could reach $100. Àngel Hermosilla, general secretary of the Col·legi d’Economistes de Catalunya, points out told La Vanguardia that the energy market is “very volatile and very sensitive to any political action,” and that the impact could be felt at the pumps in a matter of days. And so it is, for now. On the other hand, the engine shared the words of Nacho Rabadán, spokesperson for the Spanish Confederation of Service Stations (CEEES), who explained to Trece that the suppliers have already communicated to the stations “an extra cost of between 10 and 12 cents per liter for the delivery tanks this Wednesday.” That is the purchase price for the gas stations, not the final price to the driver, but it anticipates that the increases will end up being passed on. Rabadán remembers what happened in 2022 with the start of the conflict between Russia and Ukraine, at which time some stations held prices when the liter was around 1.80 euros, assuming losses, but then replacing the product “cost them up to 3,000 euros more per tanker.” On the other hand, the Organization of Consumers and Users (OCU) esteem that, if Brent stabilizes around $80, a rise of between 8 and 10 cents per liter could be expected in the coming weeks. Beyond the deposit. Eduard Conti, specialist in personal finances, counted La Vanguardia that when fuel prices rise, this affects all economic sectors, including food transportation, airline tickets, industrial manufacturing, etc. Conti points out that in Spain, inflation is currently around 2.3%, but the CPI has accumulated a 23% rise in the last five years. For his part, Philip Lane, member of the Executive Board of the European Central Bank, recognized in an interview with the Financial Times that “the magnitude of the impact and the implications for inflation in the medium term depend on the extent and duration of the conflict.” It hasn’t really gone up yet. Prices, although on the rise, are still far from the historical highs recorded by the Ministry of Ecological Transition: 95 gasoline reached €2,152/L and diesel reached €2,106/L. “I hope that we do not reach two euros, although the truth is that the oil market has been very strange for years. The only thing I can say is that for us, the fact that it is only the fifty-third highest increase in history is already good news,” counted Rabadan.

If your renovation is a pain, think about the house that cost 120 times more than its original cost: a masterpiece

by

Renovate a house It is usually an exhausting experience: budgets that skyrocket, structural unforeseen events, provisional solutions that end up being permanent. Now imagine that this home is not just any apartment, but one of the great icons of the 20th century, visited by millions of people and examined to the millimeter by historians, engineers and conservators. Then the reform stops being a domestic problem and becomes a continuous battle against time. Thus an icon was born. The assignment that changed a career The year was 1934 when Edgar J. Kaufmann commissioned Frank Lloyd Wright a weekend house next to a waterfall in Bear RunPennsylvania. The architect then took an unprecedented decision: He decided not to look at the water from afar, but to literally build on it. The work, built between 1936 and 1938, almost immediately became in a manifesto of organic architecture: concrete terraces that float over the waterfall, local stone walls that sprout from the rock, spaces that open to the forest as if the house were an extension of the landscape. By January 1938 he already occupied the same cover of time and critics proclaimed it one of the great masterpieces in the history of architecture, one capable of reconcile modernity and nature in an unforgettable image. It happens that there is always a “but” in a work, and one like this was no different. Yes. That perfect image had a disproportionate price from day one. The original cost exceeded the planned budget almost four times and reached approximately $155,000 of the time, a figure equivalent to about 3.3/3.5 million current dollars. Added to this were Wright’s own fees and the expenses derived from a complex execution in a unique but remote environment, so that the project was born already financially stressed. What should be a weekend country house became a total commitment, technical and economic, to materialize a radical vision. And we come to the material that has given the work its name, although it almost took everything away. The gesture that made Fallingwater world famous, its large columnless cantilevers over the waterfall, was also its Achilles heel. During the work, the engineer in charge of concrete warned that only eight reinforcing bars had been placed on a main beam and that, for a span of that length, it should have been duplicated steel. However, Wright rejection the objections, arguing that adding more reinforcement would damage the structure and demanding absolute confidence in their judgment. The contractor, without warning, decided to increase the steel anyway. Even so, when removing the formwork the first cantilever deformed more than four centimeters and was left with a permanent arrow that today translates into a visible slope close to two degrees. And the cracks came before inhabiting it The problems were neither theoretical nor late. Even before the Kaufmann family moved in in 1937, there were already documented leaks and cracks on the concrete parapets. As the decades passed, some balconies began to sink. more than 20 centimeters with respect to its original position, and in the nineties engineers found that the cantilevers they had failed technically and required urgent reinforcements to avoid greater risk. The house that seemed to defy gravity rested on a more fragile balance than the iconic photograph suggested. If the waterfall was the soul of the project, the rain and snow were its nightmare. Flat roofs, terraces that function as roofs for lower rooms and masonry walls holes filled with rubble They made it easier for water to find invisible paths into the interior. So much so that since the 1940s the house was nicknamed with irony by its owners for the number of buckets needed to collect leaks, and almost ninety years later an intervention of 7 million dollars intended to seal covers, inject more than a dozen tons of grout on the walls and improve waterproofing. It didn’t matter the crazy price that had been used previously, many leaks they returned with time. The overhang of the living room seen from the bridge leading to the house At the end of the 20th century and the beginning of the 21st, a structural restoration was undertaken that would be decisive: the beams were drilled and introduced steel cables post-tensioned to “pull” the concrete and recover part of its original position. That operation prevented the sinking will progressbut it did not eliminate the need for ongoing maintenance. To give us an idea, from 1937 to today, the preservation of Fallingwater has already exceeded 19 million dollars, a figure multiplied by about 120 times the initial cost of construction and which illustrates the extent to which keeping the icon standing has been more expensive than its own creation. In 1963 the Kaufmann family donated the house to the Western Pennsylvania Conservancy, which opened it to the public the following year. Since then, more than 6 million of people have visited it, and its status as a National Historical Monument and UNESCO World Heritage Site consolidated his status as one of the masterpieces of the 20th century. Paradoxically, the same audacity that generated the cracks, deformations and leaks is what gave it its symbolic force: Fallingwater, or The Falling House, embodies the rhetoric of the American dream of merging with nature and dominating it at the same time, even when that ambition required paying an enormous structural and economic price. The history of this icon shows that architectural genius is not exempt material risk. Wright’s possibly exaggerated authorship, his conviction towards engineers and contractors, and his willingness to take concrete further of prudent limitsproduced a work that was both sublime and problematic. If you will, it is also an imperfect building that has needed decades of disagreements, revisions and reinforcements to remain standing. And precisely for that reason, more than a frozen postcard over a waterfall, Fallingwater It is proof that great works are born from the tension between vision and reality, and that even masterpieces can always be, literally, at the edge of the … Read more

With Plenitude, the kWh will cost you the same 24 hours a day and, at the same time, you get a gift card for Netflix

by

If you have an electricity rate with time slotsthe watch is your greatest ally. You probably try to organize yourself as much as possible to turn on the washing machine or dishwasher in the off-peak sections, thus saving money along the way. This creates stress in many homes.especially when unforeseen events arise or there are small children at home. What alternative do we have? A rate where the kWh has exactly the same price 24 hours a day. That’s just what it offers Plenitude’s Easy Ratethat now bring a gift with you in the form of a Netflix gift card. Of course, only if you hire before next March 2. A fee to be able to put on the washing machine (or whatever) without looking at the clock Although it may not seem like it, there is a fairly considerable difference between the price per kW between the cheapest and most expensive hours. If you can use the most demanding appliances at off-peak hours, there is no problem. But, What if you get home at 7 p.m. every day? There you will have to pay the most expensive price, which can make your electricity bill skyrocket. That does not happen with the Plenitude Easy Rate. with her, the price of electricity will be exactly the same all day (at the time of writing, 0.128306 per kWh). This way, no matter how many unforeseen events you have during the day, you won’t have to worry about how much electricity costs at a certain time of day. Furthermore, once you contract the rate, the price of kWh will remain stable for 12 months. This means that, if, for example, an energy crisis occurs that increases the price of electricity, you will continue paying the same. And it does not have any type of permanence, something that not all electricity rates on the market offer. Hiring can be done in several ways, although you have the option of doing everything through the Plenitude website. In this way, you will have a 100% digital process which will only take you a few minutes. We are talking about the Easy Rate for electricity, although Plenitude also offers the same for gas, as well as for having both supplies together. Now it’s time for the promo we mentioned above, active only until March 2. Any of these rates include a 50-euro Netflix gift card that we will receive after the first month of contracting. We can use this for both a new account and one we already have. If we do numbers, it’s great: It gives you almost four months of the Standard plan. Everything together gives us an opportunity to save every month, both on the electricity bill and by removing a subscription for a while. Although yes: only if you hurry and you contract the Easy Rate before March 2. Some of the links in this article are affiliated and may provide a benefit to Xataka.

RAM memory already represents 35% of the cost of a PC. The only solution that HP finds: capable equipment

by

The PC industry – like many others – is facing a perfect storm that is completely altering manufacturing costs. As revealed by Karen Parkhill, CFO of HP, RAM memory has increased its prices so much that its specific weight in the cost of a PC is now almost unsustainable. Bad business. 35% of what your PC costs you is RAM. According to the directive, RAM memory has gone from representing an acceptable 15–18% of the bill of materials for your PCs and laptops to representing a suffocating 35%. The change is drastic, and has occurred in just one fiscal quarter. Things will get worse. This increase is due to the fact that according to HP, memory costs have doubled sequentially and have grown by 100% in a few months. Not only that: the company’s forecast is pessimistic, and they expect prices to rise as 2026 progresses. From more expensive PCs… The direct consequence for users is inevitable: the prices of PCs and laptops are going to rise. Analysts are already warning of increases of between 15% and 20% in the RRP of these devices, and in fact HP has already begun to make changes to its price tags precisely to protect its profit margins in the face of the massive increase in the price of critical components such as DRAM memory and NAND chips in SSD units. …to capable PCs. But the price is not the only thing that will change. To keep the equipment “affordable”, HP is adopting another strategy that we had already seen in mobile phones: that of “cut specifications.” This means that we will see more low- and mid-range configurations with less RAM than one would expect in 2026. The measure is clearly intended to save costs at the sacrifice of performance. At the moment they are saving the ballot. At HP they are diversifying their suppliers and cutting back on specifications and extras to compensate for the extra cost of chips. The company is even using AI systems to optimize its planning processes and has halved the time it takes to qualify new materials for agile component changes. The demand for HP PCs is still there: its personal systems division grew 11% in revenue. The company warns, however, that this trend could fall: high prices could cause sales to slow down. Damn data centers. The big culprit of everything is AI, of course, which is causing most of the production of DRAM memory chips and NAND chips to be destined for the AI ​​accelerators of NVIDIA and other manufacturers and, of course, for the gigantic data centers that are being planned everywhere. In addition, the industry is focusing on HBM memories, which are much more powerful for AI applications but which cause the production of “traditional” memories to suffer. Hello, 8 GB of RAM in 2026. For many years it seemed that 8 GB of RAM had become the de facto standard in our laptops and many PCs, but a couple of years ago we clearly made the leap to 16 GB. This crisis threatens to take us back to the past and see many “affordable” computers with 8 GB of RAM. Can we survive with this memory? Most likely yes… if our use of the equipment is relatively modest. The 16 GB really helps a lot now that we have become accustomed to opening a lot of browser tabs and applications in an era where these consume more and more memory. 8 GB seemed like a thing of the past, but we fear that we will have to learn to live with that type of configuration again.

AI consumes obscene amounts of energy. Sam Altman compares it to the cost of “training” humans

by

OpenAI CEO Sam Altman participated in an event organized by The Indian Express. During the interview made some striking statements, but the greatest of all of them was the one he dedicated to talking about what it costs to train an AI model. In fact, he complained about how many of ChatGPT’s energy consumption discussions they are unfair. Training humans also consumes a lot. The interviewer asked Altman about ChatGPT’s energy consumption and Sam Altman took a few seconds to answer the question, and then made a peculiar comparison (my bold): One of the things that is always unfair in this comparison is that it talks about how much energy it takes to train an AI model compared to what it costs a human to perform an inference query. But it also takes a lot of energy to train a human. It takes about 20 years of life and all the food you eat during that time before you become intelligent. And not only that, it took the widespread evolution of the hundred billion people who have lived and learned not to be eaten by predators and to understand science and so on to create you. The fair comparison is if you ask ChatGPT, how much energy does it take once their model is trained to answer that question compared to a human? And AI has probably already caught up in terms of energy efficiency if we measure it that way. A previous Epoch AI study corroborates that energy consumption during inference (when we actually use ChatGPT, for example) is low. Source: Epoch AI. Training is one thing, inference another.. The answer may be controversial, but to a certain extent it is logical: learning, both in the case of humans and AI, takes time and consumes many resources, but that cost is one thing and the cost of inference, of “applying that training”, is another. Once we have learned, it is not too difficult to answer things. This is what Altman is trying to point out here, who recognizes that AI does indeed consume a lot of energy in training, but that it has then become very efficient in the inference phase, when we actually use ChatGPT. The problem is that although Altman has already spoken that in inference consumption is minimal, does not provide evidence of this. The water problem is no longer a problem. He also spoke about the controversial water consumption that was theoretically carried out in large AI data centers. Although he acknowledged that this was a problem when “we used to use evaporative cooling in data centers.” Now, however, “we don’t do that,” he recalled, and made it clear that those accusations that “ChatGPT uses 17 gallons per query, or whatever” is totally false, “totally crazy, it has no connection with reality.” But again, there is still no official data from AI companies in this section. How much does AI really consume? The truth is that at this point we still do not have really clear data on how much the AI ​​consumes both in the training phase and in the inference phase. There are those who have investigated energy and water consumption and have made a mistake. wildly exaggerating the databut for example in the US, where a large number of data centers are concentrated, there is no legislation that forces transparency with those figures. Increasingly more efficient models and data centers. One of the most interesting studies was the one made by Epoch AI in February 2025, and at that time it was also concluded that AI did not actually consume as much as it was said to consume. In fact, it consumed relatively little and the models have only improved in efficiency. Chips and cooling systems have also improved, and although data centers have certainly require enormous amounts of energywe continue blindly in this section.

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

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.

painful rules cost billions in productivity

by

Although in Asian countries like Japan, South Korea or Taiwan the cancellations due to painful rules They have been around for a few yearsthey are still rare bird. Without going any further, Spain is a pioneer in the EU (Italy tried it in 2017but it did not come to fruition) and the measure came not without controversy before and after approval. Because periods and pain are managed privately, but they have a profound impact on people’s health… and also on the economy. How much does a period cost at work?. A recent study published in the Australian Journal of Social Issues How the rule affects Australia’s economy makes its importance clear: 14 billion Australian dollars a year alone in lost productivity (about 8.54 billion euros at the exchange rate). And the calculations are conservative in that they do not include health or treatment costs. The rule, in figures. The first menstruation arrives at approximately 12 years of age and since then it occurs more or less regularly every 21 – 34 days until menopause arrives, around the age of 45 – 55. We are talking about between 400 and 600 periods throughout life (except interruptions in the form of hormonal contraceptives or pregnancy). The rule, in discomfort. And if we leave the quantitative and go to the qualitative, for the majority it means a period of discomfort in the form of menstrual pain and bleeding. in the studio They speak of 90% of women under 25 years of age with dysmenorrhea, more intense pain during the first two days. Likewise, it is also quite common to experience fatigue, dizziness, lower back pain and headaches. He heavy menstrual bleeding It results in blood loss that causes a feeling of tiredness or fatigue (among other things, due to loss of iron). The study quantifies between 20 and 25% of those surveyed. The study. To carry out the research, they interviewed 1,796 Australian women with paid jobs of different age ranges (from 18 years old) to find out how common menstrual pain and other symptoms are and what the impact was on their work productivity in terms of presenteeism and absenteeism. Or what is the same: go to work but be at half speed or directly miss work. It hurts me. They came to a conclusion: those with periods between the ages of 35 and 44 suffered a noticeably greater loss of productivity than the younger ones. However, 97% had suffered menstrual pain in the last three months and 1 in 4 said they always had pain. Worldwide, menstrual pain is around 71% and only in Spainthe Spanish Contraception Society reports that almost half have to take medication for pain. From here, they calculated the range of economic impact: 7,176 Australian dollars per person per year, for a total of 14,005 million dollars. Why is it important. Because it provides economic data that is sufficiently impactful so that the management of menstrual symptoms at work is not managed individually and in isolation, falling on those affected, but rather from a collective and institutional level. As resume The research team itself “highlights the strong economic case for governments and companies to adopt policies that help people manage menstrual symptoms.” That is, with laws and policies that standardize and regulate to homogenize and streamline individual procedures in companies, but also with dialogues within the company to introduce changes in working conditions aimed at improving the productivity, health and well-being of the workforce. Among the measures proposed by the team, the modalities of teleworking or hybrid work or the schedule flexibility. In Xataka | The majority of medical discharges that are investigated are fraud.

In 2013, WhatsApp cost almost one euro. And nothing prevents Meta from charging for the app again in 2026

by

There was a time when WhatsApp was paid. This was more than ten years ago, before Goal was done with the application and ended up completely changing its structure over time. The latest beta of the app leaks something that seemed inevitable after the arrival of the announcements: a paid subscription to avoid them. He leak. WhatsApp has two versions, the stable and the beta. It is common for the code of the next beta versions to be leaked, giving us a preview of the functions that will end up reaching the final app. And the latest leak points in a very specific direction. Since you recently removed your WhatsApp account from your Accounts Center, the price of your subscription for no ads in Status & Channels has decreased. Review your subscription to accept the new price of %1$s/month; or choose to use Status & Channels free of charge with ads. Additionally, Android Authority has managed to force the code so that the app displays a message in its interface about the possibility of canceling the subscription. WHATSAPP Tricks and tips to HIDE YOURSELF TO THE MAXIMUM and maintain your PRIVACY A plausible hypothesis. So far, practically all the WhatsApp code leaks have ended up materializing: either as functions tested in the beta version, or as features that have ended up reaching the final version. One of them has been the introduction of advertising in the app, which for now is limited to statuses, promotional channels and channel subscriptions. In the case of states, the operation is very similar to what Meta applies on Instagram, interspersing ads every certain number of publications. So… what if I don’t want ads? What do you give me in exchange?. If Meta wants to implement a subscription system with any modicum of success, it will have to offer more than just removing ads in return. The subscription opens the door to new WhatsApp functions, and a business model similar to that of Telegram with its premium version. One in which the app can continue to be used without any inconvenience in the free version, but which opens the door to benefits and a better experience if we check out. Because. If the question is why Meta may intend to charge you for WhatsApp, the answer is very easy: it needs money. In 2014, Facebook paid nearly $1 billion for WhatsApp. Almost 10 years later, He had barely recovered 10% of what he paid for it.. The company continues to need ways to make the investment profitable, and betting on a subscription model is a necessary plan.
