worse

The Adamuz accident has plunged demand for the AVE by 30%. It is a fact that hides something worse: mistrust

by

The high-speed accident in Adamuz (Córdoba) has turned the Spanish railway upside down. Closures, speed restrictions and a loss of credibility in the service have directly impacted the sales of the three companies that operate on Spanish roads. And it has translated into data: a 30% drop in sales. The data. Demand for high-speed trains has fallen by 30%, according to data collected by Trainlinea railway ticket price comparator that operates in our country. The information was released by Pedro García, its general director in Europe and Spain, at an event organized by the company this week. According to this platform, the demand for banknotes has fallen by 30% in the weeks following the Adamuz accident (Córdoba) in which 46 people died after an Iryo derailed and, still under investigationthe subsequent crash and derailment of an Alvia that was traveling in the opposite direction. No trust. We could say that it hints at it but it is almost a cry: the customer is distrustful of high speed. It is not only a question of security, the drop in demand is undoubtedly influenced by speed restrictions that have been imposed and the cancellations late in the day between Madrid and Barcelona. It must be taken into account that, in just over a month, we have had the following schedule on the Spanish railway lines: Later. In the current state of high-speed lines, only one thing is clear: the train is going to arrive later. First of all, because Adif is reviewing all avenues and that requires, for example, In Madrid-Barcelona, ​​25 minutes have already been added by default to the journey. And that is in the best of cases. Because as reported by a train driver Xatakathose who drive the trains have the power to stop the train or move more slowly if they consider that the tracks are not safe or, at least, not at maximum speed. Their repeated complaints have led to temporary speed limitations that have been activated and deactivated but, ultimately, yours is the last word. This situation has been experienced with the reopening of the Madrid-Seville line. The driver, passing through the Adamuz section He stopped the train thinking that something was happening on the premises.. Then it turned out that, simply, confusion had arisen due to repairs carried out. to the plane. This distrust has caused a transfer of passengers to the plane. And the thing is that, especially companies, have been putting aside the use of the train for daily trips between Madrid and the large capitals of Spanish provinces. Especially in the Madrid-Barcelona route, where business use of the train was very high, demand for air travelers skyrocketed to the point that Iberia capped dynamic prices at 99 euros. The Ombudsman even asked the CNMC to study the price increases that were experienced in the following days in airlines and car rental companies. The rise in demand for aircraft between Madrid and Barcelona has been such that Vueling has returned to the Air Bridgea route that had abandoned in a movement where, without a doubt, The arrival of Ouigo and Iryo on Spanish roads had influenced. And an impact on the accounts. The combo of cancellations, high-speed restrictions and insecurity in arriving at the agreed time has caused a hole in the accounts of the large railway companies. According to theEconomistalready in January 2025 the losses were recorded at more than one million euros per day if only the cut in the southern corridor was taken into account. In The reason They raise the impact to a loss of 109 million euros in Malaga tourism alone. Losses that are yet to be quantified for companies but that arrive at a bad time, just when Ouigo and Iryo aspired to make money in our country after completing its landing phase. Photo | Samson Ng.

If the question is whether they forgot the elevator shaft in the tallest residential skyscraper in Spain, the answer is simple: it was much worse

by

For many years, the Mediterranean horizon was the canvas on which Spain projected its most audacious ambitions, including some extremely difficult to catalog. In times of prosperity, the sky seemed limitless. Then, each silhouette in height began to count a different story about risk, pride and collective memory. The vertical dream born of euphoria. He Intempo building started to get up in 2006at the exact moment when credit was flowing without brakes and Benidorm continued to feed its obsession with growing towards the sky as if there were no tomorrow. We are talking about two tower-shaped monsters of almost 200 meters joined by a golden diamond, a hyperbolic architecture that promised mark an era and become the new icon of the Mediterranean “Beniyork”. The project was born with generous financing from a Galician box and with a ridiculous social capital compared to the magnitude of the work, a disproportion (and a nonsense) that today sums up better than anything the climate of that Spain that believed that the cranes would never stop turning. From the symbol of the future to the monument to the bubble. But the crisis of 2008 changed the script suddenly. The loan skyrocketed above 100 million, the financial institution went bankrupt and the debt ended in hands of the Sarebthe bad bank. The works were paralyzed, the developer entered into internal conflict and the building was left with its structure practically finished but trapped in a legal and financial limbo. For years, his shadow threatened to add to that long list of phantom monsters, in fact, it was the golden skeleton that dominated the Poniente beach, a mass visible for kilometers that summarized the collapse of a model economical based on brick and easy financing. The reality was worse than the myth. Then came the stories and legends, one turned into a meme and repeated a hundred times even in media reference. It happens that, it is not that in the tallest residential skyscraper in Spain they forgot the elevator shaft, it is that the reality it was much worse. The work accumulated erratic decisions, changes in construction, salary delays, serious accidents and chaotic management in which floors were concreted without having definitive plans for the upper ones. The project was at 93% with 100% of the loan consumed, there was physical risk due to the deterioration of the structure and a bankruptcy of creditors that left the fate of the giant in the hands of judicial administrators and investment funds. The problem was not a cartoonish technical detail, but rather a chain of incompetence, financial strain and poor planning that jeopardized the building’s entire viability. The elevator hoax that went around the world. Impossible to ignore it. The story that the architects “forgot the elevator shaft” was born of an ambiguous phrase and it became the perfect headline summer 2013. The image was irresistible: a skyscraper of almost 200 meters incapable of climbing its own neighbors. However, elevators existed, of course, and They worked and were planned in the plans. The photographs and subsequent media visits clearly demonstrated. It didn’t matter, the hoax was amplified in international media that they added layers fiction, from cables that didn’t fit to impossible redesigns. That anecdote overshadowed what was truly relevant: the problem was never technical, it was structural in business and financial terms. Rescue, redesign and change of owners. Years passed, and the bad bank promoted the necessary competition to prevent the tower from deteriorating and facilitated liquidity to complete the work. Later, an investment fund acquired the assetremodeled interiors that had become obsolete and corrected questionable decisions, such as hideous finishes that obscured the homes or layouts that did not take advantage of the sea views. Finally, the top diamond was reconfigured to offer more attractive apartments and the complex was relaunched, now as a luxury residential with thousands of square meters of common areas, hotel services and international marketing. From ghost to icon. Thus, and after more than a decade of delays, the Intempo residential skyscraper finally opened its doors and began to hand out the keys to his first clients. In total, 256 homes, 11 elevatorscomplete technical plants and a structure that rested on piles designed to support both towers. From that moment on, the colossus stopped being a simple media skeleton and became a building with neighbors and real activity. Its golden silhouette left behind the stories to keep you awake, it no longer represented only the bubble and failure, but also the resilience of a city that had made verticality its hallmark. That is why it is worth saying it once again: Intempo was not the skyscraper that forgot the elevator, it was the skyscraper that survived its own time.

The special effects of 2025 are worse than those of 2010. And part of the blame lies with us viewers

by

When James Cameron released ‘Avatar’ in 2009, the film industry contemplated what seemed the future of visual effects. The film set a technical standard that, paradoxically, today’s cinema not only has not surpassed, but often does not even reach. The problem is not technological: software tools have advanced exponentially since then. But the industry has evolved in a way that everything looks worse than before. The sooner, the better. It is not necessary to go to the undisputed peak of the digital image that represented Cameron’s movie. ‘Pirates of the Caribbean: Dead Man’s Chest’ featured Davy Jones and his beard of tentacles, one of the best live-action CGI integrations ever seen. ‘Interstellar’ featured the participation of astrophysicist Kip Thorne for their spatial sequences. It is enough to compare the photorealistic texture of Na’vi or Jones with the plasticized finishes of Marvel or DC to see that something fundamental has changed in the way of producing special effects. The common denominator in all of them was time. In this analysis about the visual effects crisisit is explained that the productions of that decade had post-production calendars that ranged between 18 and 24 months. ‘Avatar’ He had two full years for the effects phase. Its consequences have started from comparable times. The spectacular images in ‘Inception’ of the city folding in on itself, another milestone of the era, took months of planning. Luxuries that are practically unthinkable today. Increasingly. The problem is the quantity. The latest studies indicate that while a commercial film from 2010 contained approximately 600 shots with visual effects, current productions usually exceed 3,000 shots. This 400% increase has not been accompanied by proportional budgets or calendars. Quite the opposite: hasty effects, poorly worked compositions and a digital homogenization that detracts from the personality of the images. Tremendous expectations In your situation analysisTreehouse Detective explains the case of the prequel to ‘The Thing’, which in 2011 remade John Carpenter’s 1982 classic. The special effects team Studio ADI, led by Alec Gillis and Tom Woodruff Jr., built physical creatures with animatronics and prosthetics over several months of pre-production. After test screenings, Universal Pictures made a decision that Gillis would rate how devastating: Almost all practical work was replaced by CGI in post-production. Audiences expected to see digital effects in a science fiction horror film and considered practical effects “old-fashioned.” Paradigm shift. This case illustrates a profound cultural shift in expectations. During the 2010s, CGI went from being an exceptional tool for what was thought unattainable with practical effects to becoming the standard. The irony is that the greatness of films like ‘Alien’ or ‘Jurassic Park’ (where CGI was mixed with practical effects) was built precisely on the tangibility of their creatures. But the industry, and with it the audience, developed a dependence on digital finishing that is associated with prestige and quality, regardless of whether the final result can be improved with traditional effects. The economy of effects. The proliferation of streaming platforms has radically reconfigured the economics of special effects. Films produced directly for Netflix, Amazon Prime or Disney+ operate with significantly lower budgets than productions destined for cinemas, while the public maintains their visual expectations. This impossible equation has put pressure on the entire FX production chain. The era of auctions. The contract awarding system has evolved towards an auction model that prioritizes cost and speed over quality. The studios put projects into competition between multiple effects companies. The one who offers to complete the job in less time and for less money gets the contract. This process creates a competitive spiral in which small studios accept unsustainable conditions in the hope of maintaining their position in the market. Studies that close. It is a system that sometimes has extreme consequences. ‘Sonic the Hedgehog’ case: after the public’s rejection of the character’s original design, Paramount ordered a complete redesign. Moving Picture Company, the studio responsible for the effects, had to redo hundreds of shots without a deadline extension or significant additional budget. The studio closed its Vancouver headquarters shortly after, with multiple sources indicating that the project had contributed significantly to their financial problems. It is not an isolated case: Rhythm & Hues, winner of the Oscar for the effects of ‘Life of Pi’ in 2013, declared bankruptcy weeks before the awards ceremony. The company had agreed to complete the job at a loss to maintain its reputation, a pattern that media outlets such as VFX Voice have documented. Visual effects artists and technicians frequently operate in crunch to meet deadlines that were unfeasible from the beginning. The lower union rate In the visual effects sector, unlike other technical departments in film, it leaves these professionals without protection against abusive working conditions. The causes. The deterioration in the quality of the special effects does not respond to a single cause, but to pressures from two opposite directions. Movie studios have optimized their production structures to maximize profit margins, outsourcing visual effects work to companies competing in a wild race. The public has developed inflexible expectations about the omnipresence of CGI, rejecting alternatives. As technology advances, the time and money available to apply it decreases. Just compare budgets: ‘Avatar’ operated on a total budget of $237 million, of which a substantial portion was allocated specifically to technological development and visual effects over several years. Meanwhile, an MCU production distributes a similar budget among multiple items (salaries, marketing) while compressing post-production calendars to just six or eight months to meet immovable release dates, established years in advance.

Science explains why the cure can be worse than the disease

by

At the time of want to lose a few kilos The truth is that many different strategies emerge, such as eliminate sweetsstart exercising more or eat much more protein. But, on the other hand, there are strategies that are really extravagant and that are spread by influencers of our society that do not have any solid foundation. The last one arrives from actor Matt Damon who claims to have lost a few kilos thanks to leaving gluten out of his diet. A discrepancy. And the reality is that science has a lot to say about this decision. Since the ‘gluten-free’ foods that now flood supermarkets were born as a medical necessity for 1% of the population. But now it has become a holy grail of weight loss following the following logic: ‘if I cut out bread and pasta, I lose weight. Ergo, gluten makes you fat.’ There is no evidence. Nutritional science has bad news for these peopleincluding the actor, since eliminating gluten does not have a specific slimming effect. In fact, if you do not have celiac disease or gluten sensitivity diagnosed, eliminating it can even be counterproductive for cardiovascular and metabolic health. It’s a calorie deficit. The first myth to debunk is that gluten, per sebe a metabolic villain that makes us accumulate fat. According to a systematic review published in International Journal of Cardiovascular Sciencesgluten-free diets are not associated with greater weight loss compared to normal gluten-containing diets in healthy adults. So… why do some people swear they lost weight by giving up gluten? The answer lies in the changes that accompany this diet, but not in gluten. And when you give up gluten, you automatically stop eating calorie-dense ultra-processed foods such as industrial pastries, cookies, refined pasta… In this way, you eat fewer total calories and this is what causes you to lose weight and not the absence of gluten. The effect of water. In addition to this caloric deficit, a pilot study in athletes noted that the rapid weight loss after six weeks without gluten was primarily due to loss of fluid and glycogen stores, not an actual metabolic advantage. Fewer refined carbohydrates mean less water retention. But if there was any doubt, another clinical trial in patients with a metabolic problem in their history detected reductions in waist circumference and triglyceridesbut without changes in weight. In this way, the researchers suggest that this is due more to better food selection and glycemic control than to a “fat-removing effect” of gluten. A flat stomach. Another of the great thoughts that can be heard in this sense is that people who do not eat wheat feel much less bloated. And this is real, but the culprit is not gluten, but from the fructans of wheatwhich is basically a type of fermentable carbohydrate that produces a lot of gas and bloating. In this way, the abdomen looks much flatter, but not because of a loss of fat. The cardiovascular paradox. But although gluten is seen as a demon, the reality is that it has several intrinsically good things. For example, gluten is often accompanied by whole grains, and whole grains are cardioprotective. This is evidenced in a study published in the BMJ with more than 100,000 participants who were followed for 26 years. This concludes that gluten consumption does not increase the risk of coronary heart disease. What’s more, when the data was adjusted, a higher gluten intake was associated with a lower risk of coronary heart disease. That is why the authors warned: promoting gluten-free diets in healthy people can reduce the consumption of whole grains and, therefore, negatively affect cardiovascular health. And in diabetes. In this case they were three large studies that showed an inverse relationship: Those who ate the most gluten had a 13% lower risk of developing type 2 diabetes compared to those who ate the least. The why? Again, the fiber and micronutrients associated with the cereal that contains gluten. The problem of the accused. When we see that something is ‘gluten free’ we may think that we are looking at something much healthier. But the reality is that sometimes, to compensate for the lack of elasticity and texture that gluten provides, The food industry often reformulates products by adding more saturated fat, more sugar and reducing the protein it contains. Furthermore, gluten-free diets in non-celiac people have also been associated with a lower intake of fiber, B vitamins and a worse long-term cardiometabolic profile. Who should give up gluten? Science is quite clear in this case: who needs it, that is, the 1% of the population with celiac disease. And logically also people with non-celiac gluten sensitivity who may have major digestive problems. For the rest of the population, eliminating gluten offers no clear nutritional benefits. On the contrary: there is a risk of spending more money on products with a worse nutritional profile, reducing the consumption of cardioprotective fiber and attributing to gluten a success that, in reality, simply belongs to eating less ultra-processed foods.

Women consistently sleep worse than men. And science has finally discovered why it is

by

For years we have been able to have a perception in many homes: the women tend to sleep worse, wake up more and feel more tired than men. This is something that for a long time has been dismissed as a subjective perception, but Science has now wanted to close the debate, pointing out that it is not only a perception, but that there is a gender gap documented. The data. The Global Sleep Survey 2025carried out on a massive sample of more than 30,000 people in 13 countries, has produced a key figure: 38% of women have problems falling asleep more than three times a week, compared to 29% of men. Something that in Spain is not a very different situation, since according to the cross-sectional studies recently published in Naturewomen have much higher scores on the Pittsburgh Sleep Quality Index (PSQI), indicating worse subjective quality. In this way, while 44.6% of Spanish women report poor sleep quality, in men the figure drops to 30.1%. A paradox. Tests with motion sensors suggest that women sometimes have higher “sleep efficiency” on paper, but it is perceived as greater exhaustion. The person responsible for this is the sleep fragmentationwhich is related to constant waking up or even in mothers due to having to get up to care for a baby, for example. The hormonal factor. It is undoubtedly one of the big differences that exist between men and women, since estrogen and progesterone levels fluctuate drastically during the menstrual cycle, pregnancy or menopause. In the specific case of menopause it can be seen as a drop in the level of estrogen, in addition to produce alterations in bone formationalso increases the immediate degradation of rest. The data indicates that 51% of the Menopausal women suffer from sleep disordersshown a big difference: 44% of women in this stage report serious problems compared to 33% of non-menopausal women. If we go to pregnancywe see something similar with physical (from discomfort) and hormonal disruptions that create a pattern of alertness that often doesn’t fully recover until years after childbirth. The mental load. Beyond the hormonal load, the social factor is, perhaps, the most difficult to correct. One of the most important is the role that women have in many cases regarding the care of other people. According to the data compiled by the University of Michigan and diverse reviews on BMJ Openemployed women wake up twice as often as their partners to care for children or dependent relatives, even when they are the main breadwinners of the home. This “caretaker” role keeps the brain in an “alert” situation, making it attentive to whether a baby cries at night or a dependent family member has any need. This causes 76% of caregivers to report poor sleep quality.since the brain cannot unconsciously disconnect to monitor the well-being of the environment. Its consequences. Poor sleep not only means being tired the next day, but also has more serious clinical consequences. One of the most important is the increase in the probability of having a metabolic diseasesuch as diabetes. In addition, it increases accelerated cognitive deterioration and causes an increase in anxiety and depression disorders. And what is interesting in this case is that the female brain in sleep deprivation is more vulnerable to emotional dysregulation. The solution. The scientific community, from the Sleep Research Institute (IIS) to publications in Frontiers in Psychiatryagrees that it is not enough to increase “sleep hygiene” by leaving your cell phone before going to sleep, for example. It mainly aims at social therapy, making changes in the structure of the home that avoid fragmentation of sleep by getting up to take care of someone, for example. But logically, if you are in a perimenopause situation, you should also choose to go to the doctor to receive pharmacological treatment whenever there is significant hormonal deregulation.

McDonald’s has not learned from Coca-Cola and has presented a Christmas advertisement made with AI. The reactions have been even worse

by

Everything indicates that the negative reaction to use of AI in Coca-Cola Christmas ad It has set a precedent… but it has not discouraged large corporations. MacDonald’s has made its own greeting with synthetic images and the reaction has been so overwhelmingly negative that the company has decided to remove the spot from social networks. Once again, issues such as creativity, aesthetics, profitability over ethics and, above all, what majority reactions they are generating are put on the table. What has happened? McDonald’s Netherlands has withdrawn its Christmas campaign generated entirely with artificial intelligence after facing a avalanche of criticism on social networks (and after being forced to disconnect comments on their profiles). The advertisement, ironically titled “It’s the most terrible time of the year”, is a perversion of the classic Christmas carols, and showed disasters with a festive atmosphere: traffic jams in which Santa Claus is involved, rebellious fir trees, unpalatable family members… the whole pack of suffering of these dates, to remind us that at least we have McDonald’s left. The problem. As happened with Coca-Cola, the problem is twofold. Aesthetically, the result is spooky.: Disturbing physics, expressionless faces, slapstick humor taken to the extreme because of that strange elastic and surreal violence of the AI. But above all, it makes viewers and critics wonder about the ethical legitimacy of this type of operationswhich completely dispense with human capital to produce more and faster. We are facing the first steps of an experimentone that corporations will put into full gear as soon as public rejection eases. Who has done it. The burger brand had entrusted production to the Californian duo MAMA (Mark Potoka and Matt Starr Spice), together with the AI ​​division The Gardening.club of the studio The Sweetshop. In a post that has since been deleted, the directors defended their work: The announcement required “seven intense weeks” of work, investing in it “more hours than in traditional production. Their central argument: “AI didn’t do it. We did it.” The controversy with Coca-Cola. The McDonald’s disaster represents the year’s second major Christmas controversy involving AI-generated advertising. A month ago Coca-Cola ignited a similar debate by launching its remake of the iconic 1995 ‘Holidays Are Coming’ spot, this time produced using generative artificial intelligence and starring animals… after the poor reception that a spot with the same concept but starring people had in 2024. The Atlanta multinational hired three specialized studios (Secret Level, Silverside AI and Wild Card), but the reaction from the public and critics was devastating. A reflection on that rejection, in reference to the 2024 ad with non-existent humans: Tim Halloran, who worked for a decade in Coca-Cola’s brand management division, stated that the campaign constituted “a violation of the brand promise” of Coca-Cola since, “for years, the core of that brand has been the idea of ​​authenticity.” Toys R Us too. Ahead of Coca-Cola’s first spot, in June 2024, Toys R Us debuted “the first commercial ad created with Sora,” OpenAI’s text-to-video tool. The one-minute spot narrated the origins of the company through its founder Charles Lazarus, combining images of the boy who would end up creating the store with the mascot Geoffrey the Giraffe in completely synthetic sequences. The industry reaction was almost unanimouswith people like Joe Russo stating in X that the ad It was “shit”. The impact on brand perception was measured Marketing-Interactivedocumenting negative reactions from 53.4% ​​of the spot’s viewers. The problem of authenticity. Behind the rejection of these ads there is a deeper problem than mere poor technical execution. In December 2024, NielsenIQ published research that revealed how viewers cognitively processed AI-generated advertising, and the result was not very promising: consumers consistently rated these contents as “annoying,” “boring,” and “confusing,” even when the technical quality was high. Neeraj Arora, professor at the University of Wisconsin-Madison, explained why the rejection is particularly acute in the Christmas context, with special attention to the Coca-Cola spot: “The holidays are a time of connection, of community, of coming together with family, and that’s a big part of what the holidays are about. But when you introduce AI into the mix, it doesn’t fit: it doesn’t fit with the festive moment, but also, to a certain degree, it doesn’t fit with Coca-Cola and what the brand stands for.” Christmas, traditionally a space of emotional authenticity, collides head-on with the synthetic nature of AI. Controversial results. The cases of McDonald’s and Coca-Cola illustrate a contradictory reality: the speed of production and cost savings that AI promises do not necessarily compensate for the loss of emotional connection with audiences. The consumers are developing rapidly the ability to identify synthetic content, and their immediate reaction is rejection.

That Instagram and Facebook are plagued by fraudulent ads is bad. That Meta is making money with them is even worse

by

Congratulations! You have won an iPhone. the king Felipe VI announcing investments. Work at Primor and get paid up to 160 euros per hour. These are just three examples of fraudulent ads that have appeared on Facebook and Instagram, but there are many more. So many, that Meta is making money with them. What has happened? An investigation of Reuters has revealed that Meta estimated that 10% of all revenue volume would come from fraudulent ads, which would total $16 billion. In an internal document from December 2024, Meta estimated that its platform serves about 15 billion “high-risk” scam ads every day. By “high risk” they mean those that are clearly frauds, like those we mentioned in the introduction, so the real number would be even higher. It seems like fraud, because we charge you more. Meta has automated systems to detect these types of ads, the problem is that the policy to block them is quite lax. The documents reveal that ads are only blocked if the system identifies it as a scam with 95% certainty. If the percentage is lower, what they do is raise the advertiser’s fee to supposedly discourage them. That is, if they continue to advertise, Meta makes even more money from frauds. The favorite site of scammers. There is more. In another document, Meta admits that “It is easier to advertise scams on Meta platforms than on Google.” The information comes from channels in which scammers discuss their methods, although they do not specify the reasons for their choice. They also estimate that a third of all successful scams in the United States occur through their platforms. Regulation. Meta is in the crosshairs of regulators around the world. The European Commission initiated action against the company for the use of data to serve advertising to users. In United Kingdom took them to trial for the same reason and more recently the United States Securities and Exchange Commission is investigating them for the financial frauds advertised on their platform. In documents published by Reuters, Meta shows its intention to reduce illegal ads, but is concerned that a sudden reduction would negatively affect its revenue. Don’t touch my publi. Meta is in a delicate moment for the huge increase in spending on AI which, despite having achieved positive results in the last quarter, has caused its shares to fall 8%. Considering that targeted advertising is Meta’s main revenue stream, a reduction on this front could shake the entire house of cards. Meta responds. Speaking to Reuters, a Meta spokesperson criticized the news, saying the documents “present a selective view that distorts Meta’s approach to fraud and scams.” He says the estimate of 10% profit from scam ads was excessive and the actual figure was much lower, although he declined to give an updated figure. According to Meta, in the last year and a half, fraudulent ad notices have been reduced by 58% and in 2025 they will have eliminated more than 134 million scams from their platform.

Windows XP’s “FCKGW-RHQQ2-YXRKT-8TG6W-2B7Q8” was legendary. Windows 95 was even worse

by

Recently we knew the origin of the legendary Windows XP activation key. That famous set of digits (“FCKGW-RHQQ2-YXRKT-8TG6W-2B7Q8“) that many of us end up memorizing became a singular demonstration that attempts to protect software do not always go well. Microsoft knows a lot about this, because its first systems to protect its operating systems and applications were even worse. The rule of “Let it be divisible by 7”. Microsoft tried to protect illegal copies of Windows 95 with a system that varied depending on the type of license. That system, however, was really weak. One of the most common licenses was the “CD Key”, which asked us for a code made up of 10 characters and two segments: XXX: could be anything from 000 to 998, but with one curious exception: the three numbers could not be the same (111, 222, …). XXXXXXX: The second segment is where a simple algorithm came into action. For the number to be valid, it was enough that it was divisible by seven. Not only that: you could enter 0. Microsoft ended up prohibiting entering all zeros, but it didn’t matter: the rule of being divisible by 7 was still fulfilled. That made coming up with compliant combinations very easy. One of the most used CD Keys was 000-000007, but 111-1111111 was also widely used Office 97 used one more digit. Instead of 10 digits, Office used 11 in two segments. XXXX: could be anything from 0001 to 9991. There were no prohibited numbers but the fourth digit had to be the third + 1 or 2. If the result was greater than 9, it became 0 or 1. XXXXXX: the same requirement as the previous one, although at least in Office 97 it did not seem to be necessary for it to comply with being divisible by 7. Thus, two keys that could work were 0001-0000007 and 1112-1111111. Things got complicated (a little) with the OEM keys. If our computer arrived with Windows 95 preinstalled, it could be that instead of a CD Key what we had to enter was an OEM Key. These keys consisted of four segments: XXXXX: represented the date the key was printed. The first three digits could be anything between 001 and 366, and the last two were the year, which could range from 95 to 03. For example, a key with 19296 as the first segment means that it would have been printed on July 10, 1996. If you wanted maximum compatibility with Windows XP, it was ideal to use 02 as the last two digits. OEM: The second segment simply had those immutable letters. XXXXXXX: the third segment had to be divisible by 7, but with another small condition: the first digit had to always be zero. XXXXX: The last segment was completely random, and could be any number of the appropriate length. Thus, to comply with validity we had keys such as 00100-OEM-0000007-00000, but it was possible to use any other such as 06900-OEM-0694207-80085. How was all this revealed? You could figure out how Windows 95’s key system worked if you’d seen enough of them. However, what really allowed us to understand this entire algorithm was the leak of the Windows NT 4.0 code, which is in fact available at Archive.org. This allowed some users to reveal both on video as in detailed articles How was it possible to discover the “check_retail_key) function of Windows NT 4.0, which was part of the system’s setupx.dll file.

You have hardly been able to escape to the news of the weekend. It happened when the morning of Paris had not yet acquired the pulse of tourism. Then, a four-man gang climbed the facade of the Louvre as if the very principle of deterrence did not exist. Everything was surprising: there was no night, no disguise of technological ingenuity, no escape into an interior labyrinth. Thus, in the seven minutes it took us humans to have a coffee, the group removed from the heart of the museum the most sensitive remains of the French imperial lineage. The most guarded museum in the world could be crossed like if it were a decoration. The material blow. He told in a detailed report this morning Le Monde that the command arrived on the side of the Seine taking advantage a context of works and the functional anonymity of an urban furniture-mountain. They forced a porte-fenêtre towards the Galerie d’Apollon (the room that condenses the mythology of state sovereignty: joyaux de la CouronneNapoleonic inheritances, diadems and colliers that condense continuity of power) and broke two high security display cases in seconds, collecting eight pieces of heritage value not translatable to the market. The operation lasted around seven minutes. The withdrawal was done along the same vertical axis with the support of two large displacement scooters. In the rush of escape, the criminals dropped the Eugenie’s crownlater recovered damaged. What they took and what they didn’t. The theft affected pieces of the corpus Marie-Amélie/Hortense (including sapphire colliers, earrings and tiaras) and jewelry linked to Marie-Louise. They were unable to extract the diamant-régent (one of the three canonical diamonds of the French canon) nor, as we said, preserve Eugénie’s crown in the flight. What is stolen is, strictly speaking, unmarketable as an entire heritage object, but its dismantling (gold, diamonds, sapphires separately) suppresses cultural and biographical traceability, which is where the irreparable lies. Structural failure. They count national media that the gap was not the cunning of others but the internal predictability: five agents for a room thermodynamically saturated with risk, a relay that reduces to four personnel in the exact strip in which the coup is carried out, a security architecture whose modernization was postponed, and a prioritization curve that armored the Joconde but it decompensated the surrounding heritage periphery. In fact, the runion and staff action (boos to management, demand for an independent audit, denunciation of years of unattended alerts) indicates that the failure was not only big, it was known and was never corrected. Political responses. The assault detonated a immediate response of Macron, of the Interior and of the judiciary, with the affirmation that the authors were going to be captured and the pieces recovered. For its part, the opposition transferred the episode to a frame of state decay: If the Louvre (symbol of the nation’s continuous narrative) is permeable during opening hours, the crack is more than museum-like. In other words, from that prism, public humiliation then operates in two planes: exterior (Country-image) and interior (delegitimization of the chain of command over heritage). The crown of Empress Eugenia de Montijo Criminal logic. We said it at the beginning. The pieces, en bloc, do not circulate. Its economic power lies rather in its deconstruction. The likely incentive is not conventional private collecting (impossible to display) but the supply on demand (unknown contractor, including state or quasi-state) or the cannibalized high margin industrial bulk. According to Le Mondehe recent pattern (Cognacq-Jay, Museum of Nature History, Limoges) shows a vector of criminal professionalization with a logistical window close to civil works, rapid emergence, cold extraction, brief departure and, sometimes, exogenous assignment. The discarding of an item in the flight suggests, perhaps, operational friction, but not global improvisation. Precedents. There is no doubt, France knows famous robberies (1911 the Joconde1976 sword of Charles, 1998 the Corot) but the qualitative leap lies in the practical deactivation of the Louvre taboo during visiting hours. The museum was closed to preserve vestiges and the criminal investigation is open with focus on escape routeabandoned equipment, construction perimeters and cameras. In fact, the hypothesis of a foreign commission is not ruled out, nor is the performance of a cell trained in high-density urban theater patterns. Hunting status. From what is known, the investigation focuses in four authorsscooters and routes already mapped, with cameras analyzed and forensic material in progress. One damaged piece was recovered, but eight remain missing. Plus: the probability of intact recovery decreases with time because the thief’s rational incentive is, a priori, to disassemble, volatilize and recombine. The cultural loss is absolute if the components are assembled in another vector or if the metal is melted and sold through other channels. What the robbery reveals. The reputational implosion now forces us to accelerate what years of internal warnings They did not move: comprehensive shielding, redistribution of personnel due to real risk and not due to tradition, closing of logistical windows associated with civil works, and a redefinition of the security perimeter by layers, not only by a single idol (the Joconde-Gioconda). The only “advantage” of an open-hour robbery with global symbolic production is that it makes it politically unaffordable to return to the previous status quo. If you also want, the episode, rather than pointing out an unusual criminal genius, points to the country itself. The escape in seven minutes did not measure the capacity of the thieves, but rather the exact time in which the State left open the possibility that the largest museum in the world could be treated like the entrance to a bathroom in full public service.

110 years later we finally know what sank the ‘endurance’ in the Antarctic. The culprit was not the ice: it was much worse

He Endurancethe legendary ship of Ernest Shackletonbecame a symbol of resistance and heroism after its sinking in the icy waters of the Weddell Sea in 1915. There began the myth, because during more than a centuryits end was wrapped in a halo of mystery, attributed to the lethal coup of the ice against its rudder. Now, science He has revealed That the truth was more complex and, in a way, disturbing: the ship was never prepared to survive. The myth and the truth. As we said, for more than a century, 110 years to be exact, Ernest Shackleton’s heroic story and his antarctic ice crew was accompanied by the conviction that the endurance was the wooden ship more robust of his timevictim of a fatal blow of the ice against his helm. However, Recent research They have dismantled that narrative. The thorough analysis of the wreck discovered in 2022 reveals that the ship I was convicted From the beginning: it was not a single impact that sank it, but the accumulation of compressive forces that crushed their weak structure and, very important in the final story, Shackleton I probably knew When he left for Weddell. The expedition trapped. Endurance sailed in 1914 with the ambitious plan of cross the Antarctica on footbut at the beginning of 1915 he was caught in a solid ice. For ten months the crew resisted on board until the pressures began to deform the ship. The covers were combined, the helmet vibrated with a crash and the newspapers of the sailors picked up the sound of the creak of the wood under huge forces. On October 27, 1915 Shackleton ordered to leave the shipand weeks later the helmet ended up sinking after a succession of pressure onslaught that started masts and opened the structure in two. Idealized cross sections of the first Antarctic ships. The endurance was of the type (a); The type Deutschland (B) Fortress with mud feet. Far from being the invulnerable ship of the legend, the endurance was born as a ship of Polar and Hunting Tourism of bears and morsas in the Arctic. Its design lacked the critical reinforcements to survive trapped in an icy sea: it had no diagonal beams that kept the bands of the helmet or racks that supported the machine room, its most fragile area. Over there, According to witnesses As the scientist Reginald James or Captain Frank Worsley, the iron plates combined and the soils bulging while the ice pressed incessantly. The Rudder and the keel departed, but they were not the cause but the consequence of that structural weakness. Pecio discovered in 2022 Shackleton knew it. It is one of the keys that light has seen now. The most revealing thing is that Shackleton I did not ignore Those defects. He had participated in rescues from other ships shattered by ice and advised the German Wilhelm Filchner reinforce with diagonal beams Your Deutschlandthat thus managed to survive eight months trapped. Even in a letter to his wife he admitted that the endurance was not as solid as The Nimrodthe ship of your previous expedition. Even so, He acquired it Without modifications, moved by the urgency of undertaking a colossal project in the midst of their debts, their personal failures and competition with other explorers for reaching Antarctic glory. The re -written history. He New study of Jukka Tuhkuri Disassemble the myth of the invulnerability of the endurance, showing that it was an inappropriate ship faced with a relentless environment. However, this finding does not decrease the figure of Shackleton, but it frames it With more realism: A leader who risked aware that the adventure could cost the ship, but that miraculously saved his entire crew. At a time when polar exploration was a jump of faith towards the unknown, the wreck of the endurance was not only the end of a ship, but the proof that even the stronger wood yields Before ice pressurewhile human will manages to survive where the technique fails. Shared destination. The truth is that the Endurance drama It was not an isolated episode. Decades earlier, in 1876, twelve American whales They sank in front of Alaska for lacking the necessary reinforcements against compressed ice, dragging with him the livelihood of hundreds of families. Something similar happened in 1903 with The Antarctica Swedish ship trapped and shattered in the Weddell Sea. And, in contrast, the case of Deutschland It demonstrates how simple modifications could make the difference between sinking and survival. If you want also, all these episodes draw a pattern: polar ice does not forgive improvisations or risk economies. Shackleton, with his leadership instinct, achieved what other captains They did not achieve: save all his men, although at the expense of expose them to sacrifice of a ship that had never had to face the brutality of the white continent.
