Mexico has placed impossible tariffs on Chinese cars. What they didn’t imagine was that the cars were already there.

Export to buckets. That was China’s goal in 2025 towards Mexico. Alerted by the enormous tariffs that the country was going to impose, as it has been, Chinese manufacturers have done everything possible to be faster than the Government. Now, exporting a car to Mexico from China is unfeasible. But the Chinese cars arrived months ago. taxes. Was a 20% tariff on Chinese cars too little? Mexico believes so and that is why, since January 2026, it has been applying a new 50% tariff on imports of products arriving from countries with which it does not have trade agreements. Come on, what Chinese cars now have to pay 50% tariffs to enter Mexico. The measure, explained in Motorpasión Mexico has a bit of a protectionist flavor compared to China or India (the latter country has Mexico as the third country to which it sends the most cars). But, above all, It has a lot of nods to the United Stateswith whom Mexico has a special trade agreement that has been at risk since Donald Trump returned to the White House. when you go. I will tell an anecdote from the writing of Xataka. In our Slack we have a reaction from Chenoa to point out to someone that we were already contemplating writing on a topic that he now proposes to us again. You know: “when you go…”. And that is what has happened to Mexico with China. Manufacturers, alarmed by the possibility of tariffs being raised in their country of origin (as has finally happened) began to send all the cars they could to Mexico. The result: 625,187 cars exported to Mexico in one year. They have done “a Chenoa” to Mexico. one in three. To understand the magnitude of exports, according to data from the China Passenger Car AssociationMexico is the country to which China exported the most cars in 2025. These more than 625,000 vehicles surpassed those purchased by Russia (582,738 units), which has serious difficulties in obtaining vehicles from abroad. The United Arab Emirates, with 571,937 cars imported from China, was the third country that received the most cars. The figure is enormous. And in Mexico around 1.5 million cars are bought a year. That is, if in 2026 each and every one of the cars exported by China were sold, in 2025 we would be talking about one in every three sales in the country being from Chinese manufacturers. How many are available? Those exports, of course, leave a pool of cheap cars in stock so the impact of Chinese cars on the market will continue to be felt for some time. It must be taken into account that it is calculated that China had already taken 15% market share. The storage of these cars, everything indicates, guarantees that Chinese brands continue selling at the same rate throughout the year. They point out in Motorpasión Mexico In 2025, it is estimated that Mexicans will buy just over 400,000 cars of Chinese origin. The only question is how many of them belong to the more than 630,000 cars imported last year and how much is the stock since a part of them must have been imported into the country in 2024.

In 1832 Britain realized that it didn’t have much sun. Since then, a law requires that houses have good light

If there is something that the United Kingdom could blame for its geography and climate, it is the gray days. Rare is the moment when the sun is not covered by clouds in Mary Poppins’ country, where natural light has become a scarce commodity to fight for. So much so, that there is a “right to light” by which homeowners can legally prevent new construction that obstructs natural light rays into their homes. This law is actually an easement established in 1832 by which the owner of a building with windows that have received natural light for more than 20 years has the right to prohibit adjacent constructions that limit it. That is, historically, a person was entitled to this if natural light and air had passed freely through their windows during that time and been enjoyed without disturbance. And these homes protected by the ordinance were marked with the “Ancient Lights” sign. Therefore, if a neighbor tried to violate this by building a structure or planting trees, the owner had the power to sue him for the “nuisance”. Of course, it is important to note that these do not only affect direct sunlight. But it gives the right to a minimum level of natural lighting, not direct rays of the sun. Although this urban planning law has undergone quite a few changes since its inception, the power of property owners to demand natural light continues to be debated in British cities. Nowadays, These “Ancient Lights” signs are still found on buildings around London and other counties such as Dorset and Kent. And the law, more than 100 years later, continues to be the protagonist of all types of litigation, becoming a headache for judges, lawyers and construction companies. The idea of ​​”having the right to light” Let’s go into more detail. A question that arises from this concept is: how much natural light does a person have the right to? And that is precisely where this law has several legal loopholes. Because a building owner’s windows don’t even have to be completely blocked by a neighboring obstruction for that right to be invoked. You simply have to maintain the same level of lighting that the owner has experienced for twenty years, something that is quite diffuse. In the 1920s, Percy Waldram, an expert in this law, proposed a system to standardize the sufficient amount of light that people could claim. He suggested that “common people” required at least one foot-candle (a measure of light intensity) for reading and other work. If the builder, including a homeowner planning an extension, identifies a risk affecting light rights, they must notify the affected homeowner and engage with them to reach an amicable agreement. This could be as compensation or a redesign to rectify or mitigate the problem. However, if there is a dispute, There are two ways to take legal action: damages and/or a court order. The first consists of granting a sum of money to compensate for the loss. The second may require demolition of part or all of the new building unless some other structural change can remedy the problem. The latter is usually too expensive. The idea for many years was that if a property owner did not take immediate steps to obtain a court order, the only remedy available to them was damages. However, a 2010 case left builders stunnedas the court held that it was possible to obtain an injunction even after the completion of the new building. In another more recent case from 2020the court granted an injunction to a property owner two years after the completion of the infringing work. The court found that the builder had proceeded with full knowledge of the risk he was taking. Is there a similar law in Spain? The easements They also exist in Spain. It is the right that the owner of a property has over the adjoining property that limits the proprietary powers of the owner thereof. In fact, it is not so uncommon to find cases in our country (especially in individual homes), in which Your neighbor has one or more windows that face directly onto your property. Is it legal? As regulated by the Civil Code in article 580no party wall can, without the consent of the other, open any window or opening in a party wall. Otherwise, the owner of a wall that is not a party wall and that is adjacent to the back of another owner may open windows or openings in the same wall. to receive lightsas long as it complies with the premises established in article 581 of the Civil Code. Furthermore, as stipulated in the article 582 of the Civil Code: “You cannot open windows with straight views, nor balconies or other similar overhangs, over the neighbor’s property, if there is not two meters of distance between the wall on which they are built and said property. Nor can you have side or oblique views over the same property, if there is not 60 cm of distance.” In Xataka | If your renovation is a pain, think about the house that cost 120 times more than its original cost: a masterpiece In Xataka | 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 Image | Chris Flexen

ended up sneaking in errors and references that didn’t add up

Artificial intelligence has become an everyday tool for millions of people. Today many use it to write emails, summarize documents or translate texts in a matter of seconds. However, this speed has a less visible side: generative systems can also make mistakes, invent data or alter sources without the user immediately noticing. When these errors appear in one of the largest encyclopedias in the world, the situation changes completely. That is precisely what has happened on Wikipedia with a series of translations carried out with the help of AI. The opening episode. It all started within the Wikipedia community itself. Some editors began reviewing recent translations and noticed something strange: certain texts included phrases that did not appear in the cited sources or references that did not seem to fit with what the article stated. According to 404 Mediathese translations were part of a project promoted by an organization that sought to expand the presence of Wikipedia content in different languages ​​using language models to speed up the process. When translation invents. As editors began to examine these translations in more detail, the problems became more evident. One of the cases cited by 404 Media is that of a draft article about the French royal family La Bourdonnaye. The translated text included a reference to a book and a specific page to explain the origin of the family. However, when editor Ilyas Lebleu, known on Wikipedia as Chaotic Enby, reviewed that source, he discovered that the page cited was incorrect. Lebleu added that, when doing a quick review of several translations, he also found interchanged references, phrases without a source, and cases in which paragraphs were added based on material unrelated to what was being written. It was published or remained in draft. The case also raised a relevant question: whether these errors had appeared in already published articles or whether they were detected during the review process. At least one of the problematic examples was identified in a draft translation, allowing editors to revise it before it was finalized. With the material provided here, however, it cannot be stated how many translations with problems were published and how many remained under review. Who is behind these translations. Here appears the name of Open Knowledge Association (OKA), a non-profit organization that claims to work to improve Wikipedia and other open platforms. As the organization itself explains on its website, its model consists of offering monthly stipends to collaborators and translators who work full-time expanding the encyclopedia’s content, and “taking advantage of AI (large language models) to automate most of the work.” According to 404 Media, editors who investigated the project concluded that it relied on contractors. The editors’ response. As more problematic examples appeared, the Wikipedia community decided to intervene. The editors reviewed the operation of the translation project and ended up establishing new restrictions for those who participated in it. OKA-linked translators who accumulate four strikes for unverifiable content within a six-month period may be blocked without additional notice if a new case appears. Additionally, content added by a translator that ends up being blocked may be removed preventively, unless another reputable editor takes responsibility for reviewing it. OKA explains. The organization mentioned in the debate also offered its version of the events. Jonathan Zimmermann, founder and president of the Open Knowledge Association, explained to the aforementioned media that the project’s translators work on an hourly basis and that there is no fixed goal of articles per week. In addition, he admitted that “errors happen,” although he defended that the system includes human verification and review of sources. Following the discussion on Wikipedia, he added, the organization is introducing a second review with another AI model to detect possible errors before publishing, and is studying the possibility of adding peer review mechanisms if necessary. Images | Oberon Copeland @veryinformed.com | Luke Chesser In Xataka | Sam Altman says he’s terrified of a world where AI companies believe themselves to be more powerful than the government. It’s just what you’re building

Sam Altman has spent his entire life saying one thing and doing exactly the opposite. And this time it didn’t even take 48 hours.

A Mecano’s great song —I know, this is very Kiss FM—he said that ‘the face you see is a Signal ad’. And in case any of our painfully young readers don’t know, Signal is a brand of toothpaste. And if there is anyone whose face is exactly like that, it is Sam Altman, CEO of OpenAI, who with a perfect and convincing smile tries to convince the world that his company is just as perfect and convincing. For many people, today is not the case. what has happened. These days we have seen how the US and its Department of Defense (or War, as they like to call it now) have decided that if any AI company wants to work with them, they are going to have to let them use the AI ​​as they see fit. That we have to massively spy on people? He spies on her, totally, we have already done it. What should we tell AI to develop lethal autonomous weapons? Well too. Anthropic stands. But lo and behold, precisely the company that was working with the Pentagon He said that oranges from China. Anthropic, which had been collaborating with the Government for months—Claude was used for the arrest of Nicolás Maduro—, has made it clear that there are red lines that he will not cross. If Anthropic doesn’t want to, let OpenAI do it. At the Pentagon they have threatened to turn Anthropic into a pariah company, but at the moment they have not made any official move. What has happened is that the US Government has decided to change its technological partner. OpenAI has replaced Anthropic and appears to have reached an agreement to work with US defense and security agencies. Sam Altman seizes the opportunity. This has been indicated by Sam Altman, who in an ad on Twitter (I still resist calling her “X”) explained that her company had agreed deploy their models on the US War Department’s classified network. The curious thing is that this agreement establishes the same red lines that Anthropic had: no espionage on American citizens and no autonomous weapons. In the official announcement they even highlight that their agreement “has more safeguards than any previous agreement for classified AI deployments, including Anthropic’s.” There is, for example, one more requirement: that their models not be used for “social credit” systems with which citizens are rated based on the information collected from them. But. Although both Sam Altman and the company’s blog appear to place limits on the War Department’s use of its AI, the terms of that agreement contradict Altman’s claims. The announcement mentions a specific paragraph of the agreement that explicitly states the following: The War Department may use the AI ​​system for all lawful purposes, consistent with applicable law, operational requirements, and well-established security and oversight protocols. “The AI ​​system will not be used to independently direct autonomous weapons in any case where human control is required by law, regulation or Department policy, nor will it be used to make other high-risk decisions that require approval from a similarly competent human decision-maker.” Mass spying on American citizens is legal in certain scenarios as part of the Patriot Act that was passed after the 9/11 attacks, and that would allow AI to process data and communications collected by mass surveillance systems. Jeremy Lewin, a State Department official, has indicated that this agreement “flows from the pillar of ‘all legitimate use’”, and points out that what Altman proposes regarding red lines is not as clear-cut as it seems. Internal protests. Last Friday at 5:01 p.m., Anthropic was due to accept the Pentagon’s terms, but it did not do so. During that morning, several OpenAI and Google employees showed their support for the ethical and moral positioning of the rival company, and almost 800 of them (681 from Google, 96 from OpenAI) signed an open letter entitled “We will not be divided.” Altman says one thing, does another. In an interview with CNBCSam Altman said on CNBC that despite all the differences he has with Anthropic, “I trust them as a company, and I think they really care about safety.” On Thursday, the CEO of OpenAI sent an internal statement expressing his desire for “things to de-escalate between Anthropic and the Department of Defense.” The message came to nothing less than two days later, when he announced the agreement with the same Department.

On Reddit they appeared several messages that encouraged users to “Cancel ChatGPT” with thousands of positive votes and also thousands of comments in which the tone was indignant with the way in which OpenAI and Sam Altman have taken advantage of this circumstance. We have seen critical movements in the past —Facebook, Netflix—, but it usually happens that after these first moments, companies end up recovering from the criticism and even come out stronger for a simple reason: Human beings have very bad memories.

In the 70s Álava left an entire town under its airport. What I didn’t know was that it was hiding a treasure of 5,000 medieval coins.

He Vitoria airport It may not be the largest, the best connected or the busiest in the country, but it stands out for the volume of merchandise it moves. Last month it exceeded 5,400 tonswhich consolidates it as Aena’s fourth busiest aerodrome, only behind Barajas, El Prat and Zaragoza. If the Alava terminal works, moving cargo, planes and hundreds of thousands of passengers, it is thanks to an old village that ended up buried in the 70s: Otaza. The most curious thing is that he did it with a hidden medieval treasure. The price of growing. In the 1970s, Álava businessmen found themselves with a dilemma. If they wanted to continue growing, they needed better connections, regular flights that would allow them to reach the rest of the metropolises in Spain and Europe. They had the Salburua airfieldinaugurated in 1935, but it did not seem like the best solution, so the technicians had to look for alternatives. And they found her. After evaluating several locations in the region, such as Ullibarri Arrazua. Salvatierra or Zurbano concluded that the best solution was to set up a new aircraft facility on the land of the town of Foronda. A work in record time. The project had the support of the Provincial Council and moved forward with astonishing speed. At least for the deadlines that infrastructures the size of an airport usually handle today. The construction of the aerodrome was approved in 1972 and in 1976 Civil Aviation gave its OK to the first phase. The works, remember The Mailinvolved the construction of a 2,200 x 45 m flight runway, in addition to the operating systems. The work (and procedures) continued to advance at a good pace during the following years. In 1978, the institutional machinery was launched to contract the control tower, accesses and urbanization and just two years later (the January 30, 1980) the ministry officially opened Vitoria Airport to national and international passenger traffic. In April of that same year Iberia inaugurated one of its most important lines, the one that exalts it with Madrid. Sew and sing, right? Not at all. The construction of the terminal encountered a problem: the proximity of a small village that ended up being located 370 meters from the runway. His name: Otaza. The population had a long history and it even had its own church, but it was not what is said to be very populous. It is estimated that at the beginning of the 19th century it hosted only about thirty of people, more or less what there were in 1974, when according to The Mail 26 neighbors lived there. The Álava authorities were therefore faced with a dilemma: What should take priority, the new airfield or a village with a handful of families? And the pickaxe arrived. The expropriation was not what is called simple. Not all the neighbors willingly agreed to leave their homes and in fact there were a few ‘numantinos’ (not many, it is true) who did not leave until the end. Their efforts did not prevent the bulldozers from taking Otaza away. In October 1979, the regional press reported how, after a break and despite not yet having reached a total agreement with the neighbors, the authorities had resumed the demolition work. The Bishopric had fewer objections, which reached an agreement that allowed the village temple to be demolished. The pickaxe had to work little. A few days later, on November 2, the demolition was completed. A town to remember. That was the end of Otaza. Although in its day the town had welcomed dozens of people, had a church and services, the expropriation of the land and the demolition works sealed its fate. Shortly after completing the works, the authorities agreed the disappearance of the council, which is now part of Astegieta. However, as EITB recalls, it was not the only town affected by the works on the new terminal. Antezana of Foronda He also paid a ‘toll’ for Álava to have its own flights. One last surprise. Otaza’s story could have ended there if it weren’t for the fact that shortly after his ‘death’, in April 1980, a family decided to take a walk through the grounds. During the walk, as they passed near the church of San Emeterio and San Celedonio, they found a jar with coins. The piece caught their attention enough to report it to the authorities, who confirmed that it was a curious treasure: more than 5,000 coins of copper and silver minted during the reigns of Alfonso I of Aragon and Alfonso VIIIbetween the 12th and 13th centuries. Today it is known as “the treasure of Otaza”. Images | WikipediaGoogle Earth and Mikelo (Flickr) In Xataka | Barajas needed to improve its roads but a baroque hermitage made it complicated.

“We didn’t expect this.” A Ukrainian drone has revealed a Russian arsenal in a warehouse, and the surprise has been huge: the missiles are animals

From the early stages of the Russian invasion of Ukraine, when tanks were advancing while logistics columns were bogged down and fuel was scarce, the war began to reveal an uncomfortable paradox: the more modern it became in the skies, more “medieval” It was done on the ground. In fact, in that space where drones, satellites and trenches coexist, the return of solutions from the past apparently overcome was an early sign that the conflict was going to be, above all, a test of resistance. The latest Ukrainian discovery has confirmed that the wear and tear is tremendous. The return of the war of attrition. The irony is that the war in Ukraine has been shedding any illusion of modernity to return, as the days go by, to brutal logic of wear, one in which the quantity and capacity to take losses They weigh more than any technological “game changer”, and where the Russian army, pressured by the massive consumption of material and men, is beginning to show obvious signs of logistical exhaustion. On the southern and eastern front, the shortage of armored vehicles and modern systems is no longer hidden with silence, but is manifest in improvised solutions reminiscent of conflicts from another era and centuries, while Moscow insists on maintaining constant pressure on Ukrainian defenses at any cost. Cavalry in the 21st century. This wear and tear became visible at the beginning of 2026 when Ukrainian units detected and neutralized Russian assaults carried out on horseback, a tactic that seemed banished from modern warfare but that reappeared in sectors such as Oleskiivka in response to lack of means conventional. We are talking about small assault groups that advanced mounted, supported by prior reconnaissance, in infiltration attempts that ended up being aborted by drones and fire defensive, leaving such an absurd image (and repeated) as revealing: many horses survived, but the soldiers did not, and the Russian army confirmed that it was willing to resort to any available resources to sustain its offensive. The drone and the impossible arsenal. Now, the scene What finally condensed this drift came several weeks later, when a Ukrainian drone sneaked through the destroyed roof of a hidden warehouse, several kilometers from the line of contact, with the usual expectation of finding ammunition, fuel or military vehicles. What happened gives an idea of ​​these four years of slow war that has worn down both sides. Instead of artillery and technology to advance, the camera showed something that looked like something out of a rural garage: aging civilian cars, motorcycles from another era, and saddled horses, an “arsenal” as unexpected as it is eloquent of the state of the war in many areas. The message. “We didn’t expect to see this. It was really unusual,” said the drone pilot. to the Insider mediumspeaking on condition that he only be identified by his callsign “Cosmos.” “We were hoping to find some armored vehicles,” he added. He video It went viral because it summarized in seconds the real state of Russian logistics, but also because it demonstrated that those animals were not an isolated anecdote, but part of a system that already uses cheap and expendable media to move and attack under the constant threat of drones. Russia and the logic of sacrifice. For the Ukrainian commanders, this discovery is neither trivial nor a simple curiosity, but rather proof of a way of waging war based on accepting massive losses of material and personnel, replacing armored by civilian cars and horses because they are easier to replace. This logic, which prioritizes the attrition of the enemy, even if the cost is enormous, explains why Moscow continues to advance slowly, launching assaults with many times obsolete or improvised in regions such as Donbas, even when the monthly casualty figures, according to NATOreach levels that are difficult to sustain. If you will, the drone that expected to find missiles and found animals ended up portraying, better than any report, a war that moves backwards while consuming everything at hand.

The US recorded something strange underground and didn’t know what it was. Now he has just accused China of pressing the nuclear button

During the Cold War, even at times of greatest nuclear tension, Washington and Moscow maintained an unwritten rule: If a test was done, the world had to find out. The explosions were political signals as much as military experiments, designed to be seen, measured and, of course, feared. Therefore, talking about detonations so small that they barely leave a seismic trace and about tests designed not to be detected, generates great concern. The United States just accused China exactly that. An unprecedented accusation. It happened last Friday, when the United States denounced China for having carried out at least a nuclear test with explosive performance in 2020 and to prepare for other low-power ones, a complaint made in Geneva through by Undersecretary Thomas DiNanno just as the classical arms control framework is collapsing after the New START expiration. According to Washington, Beijing would have resorted to decoupling techniques to dampen seismic signals and hide underground detonations, an accusation of enormous political significance because it breaks the previous ambiguity and indicates for the first time a specific date, the June 22, 2020in the midst of debate over whether the United States should recover the option of testing nuclear weapons again. The diffuse limit. The technical and legal background is key to understanding the controversy, since both China and the United States have signed, but not ratified the Comprehensive Nuclear Test Ban Treatyallowing subcritical testing no self-sustaining nuclear reaction but prohibits any explosion with measurable output. Washington maintains that Beijing would have crossed that line with evidence very low powerdifficult to detect, while the body in charge of verification, the Comprehensive Nuclear Test Ban Treaty Organization, ensures that its network did not detect no event compatible with a nuclear explosion that day, thus underlining the fragility of a control system that never came into full force. Lop Nur, satellites and silent expansion. It we have counted other times. American suspicions are also supported by satellite images and intelligence analysis that point to intense activity in the historic Lop Nur polygonwith new excavations, tunnels and drilling that could be used for both subcritical tests and higher performance detonations. This movement fits with the rapid expansion of the Chinese arsenal, which would already exceed the 600 nuclear warheads and could reach a thousand before 2030reinforcing the perception in Washington that the real strategic challenge is no longer Moscow but a Beijing with the capacity and will to challenge US military primacy. A new nuclear race scenario. The Washington complaint comes accompanied by a clear political message: without binding limits, transparency or verification mechanisms that include China, the system inherited from the Cold War ceases to serve, and the United States reserves the right to adopt “parallel steps”including the resumption of testing, if it considers that other actors are breaking the rules. Beijing strongly rejects accusations, claims its moratorium and its doctrine of no first use, but the simple verbal clash shows a change of phase, one with the risk that the end of New START and mutual distrust open the door to a new nuclear race in which small, almost invisible explosions can have enormous strategic consequences.

Researchers extracted photos and statuses from 3.5 billion WhatsApp users. Meta didn’t react until they told him.

Between December 2024 and April 2025, a team from the University of Vienna identified 3.5 billion active phone numbers on WhatsApp (practically its entire user base) from a single server and without encountering too much technical resistance. They processed more than a hundred million numbers per hour and extracted not only the existence of accounts, but also public keys, profile photos, status texts, and device metadata. They did it without having to hide, from the same university IP, same server, five accounts. For four months, no one in Meta noticed. Why is it important. This is not the first time that this vulnerability has been demonstrated, as it has already occurred in 2012 and 2021but the first at this scale and speed. The finding exposes a structural contradiction in WhatsApp: Your architecture should show whether a number is registered to enable contact discovery… …but that functional need collides with the privacy of its users. Knowing who uses WhatsApp in countries where it is prohibited, such as China, Burma or North Korea, can have serious consequences. There they detected 2.3 million, 1.6 million and five accounts respectively (not five million, just five). The investigation, published a few weeks ago in NDSS 2026shows that this crack not only persists, but has widened. The context. The researchers developed ‘libphonegen’, a tool that reduces the search space from billions of theoretical combinations of possible mobile phone numbers to “just” 63 billion real candidates for 245 countries. Using unofficial WhatsApp clients that directly access the XMPP API, they queried these numbers at a rate of 7,000 per second. Neither his IP was blocked nor his accounts sanctioned. Meta did not respond until researchers explicitly reported the finding in March of this year, and countermeasures did not arrive until October, just a couple of months ago. The figures. He dataset resulting five times higher the scandal of scraping from Facebook 2021: India leads the document with 749 million users (21% of the total), followed by Indonesia and Brazil. In Spain, 46.5 million accounts. 81% use Android. More than half have a public profile photo. 29% have the status text visible. Between the lines. The researchers were able to infer the operating system by analyzing initialization patterns of the cryptographic keys. Android starts certain identifiers at zero. iOS does this in random values. This detail matters because iPhone users are higher-value targets for attackers. They also detected that public keys are reused. They found 2.3 million different keys used on 2.9 million different devices. In Burma and Nigeria, tens of thousands of numbers shared the same key, pointing either to faulty implementation or outright fraud. They even found twenty American numbers that use a private key composed only of zeros. In detail. The method is not limited to confirming the existence of the accounts. For each one they extracted public keys, timestamps and the list of linked devices. This allows you to build detailed profiles without accessing the content of the messages. The age of the device can be estimated by counting key rotations. The “popularity” of a user is inferred by the frequency of depletion of their prekeys single usewhich are consumed every time you start a new conversation. Researchers downloaded 77 million profile photos of the +1 rank (prefix for the United States and Canada) in a matter of hours. 66% of them contained recognizable faces. They also found disturbing status texts, such as those from traffickers listing prices, accounts business advertising drugs or publicly visible corporate emails from governments and armies. And now what. Meta has deployed probabilistic cardinality counters to limit how many unique accounts a user can query without blocking legitimate contact discovery. It has also restricted bulk access to status photos and texts. The researchers confirmed that the measures work in subsequent tests. But no countermeasures protect those who were already listed during the months in which the system has been wide open. The big question. For four months, from a university server without even hiding their identity, they looted practically the entire user base of the most used application on the planet without anyone at Meta realizing until they were explicitly told. If these researchers were able to do it under these conditions, who else did it before without telling anyone?

A Russian family lived isolated in Siberia for more than 40 years. He didn’t know about World War II or the space race.

In the cold, vast and desolate siberian taiga one would expect to find spruce trees, maples, streams and acres covered in frozen silt. Maybe (hopefully) some lone pso or wolf. What no one would include on that list is what he discovered around mid 1978 an expedition that flew over a mountain located more than 240 km from any human trace. There, in the middle of the Abakan mountain rangea group of geologists came across a family that had been isolated for 42 years. Its story still fascinates today. And that cabin? Such a question must have been asked 47 years ago by a group of Soviet geologists flying over the Siberian taiga, an area rich in oil, gas and mineral reserves. He ran summer of 1978 and the team, led by Galina Pismenskaya, was traveling by helicopter in a region of Siberia located 160 km from the border with Mongolia when the pilot saw something between the trees. Something unexpected. A rudimentary cabin with a small garden. In most parts of the planet, such an image would be of little interest, but Pismenskaya’s team was supposedly in an unpopulated area. In fact, the Soviet authorities were not aware that anyone lived there. The nearest houses were supposed to be more than 200 kilometers away, so the question was obvious… What the hell was that shack doing there, built next to a stream, among trees? They were so intrigued that geologists decided to land. “We come to visit”. The impressions of Pismenskaya and her colleagues when approaching the hut we know them thanks to Vasily Peskova Russian journalist and traveler who would later interview the protagonists of that story to collect it in a book. Upon landing, the researchers found a hut made with the little that the taiga offered: bark, branches, trunks and pieces of wood blackened by humidity. On one side there was a tiny window. On the other side there was a door through which an old man appeared. “Like something out of a fairy tale”, would relate some time later Pismenskaya, who recalled that the man was barefoot, was wearing a patched shirt and pants and sported a scraggly beard. “He seemed scared. We had to say something, so I started: ‘Greetings, Grandpa! We’ve come to see you.’” The fact is that that old man was not alone. When they entered the hut with him, the geologists discovered that he lived with his four children. They all shared that wooden construction without rooms, blackened by smoke, cold and with the floor covered in shells. Upon seeing the new arrivals, one of the young women began to pray, scared. Another, hidden behind a post, ended up collapsing from suffocation. Logical. The family had not seen another human for four decades. Dating back to 1936. The old man in question was called Karp Osipovich Lykov and the fact that he lived there, in conditions almost medieval people, hundreds of kilometers from any hint of civilization and surrounded only by his children, is explained in light of what happened in Russia at the beginning of the 20th century. Just like his Karp family was an old believera member of a church split from Orthodox Christianity that embraced the ancient liturgy and ecclesiastical canons. The path of Karp’s coreligionists had diverged from the Russian Orthodox already in the 17th century, after Nikon’s reformwhich made them outcasts. This had happened in times of Peter I…and with the Bolsheviks. This harassment affected the Lykov family directly. Around 1936, a patrol shot his brother on the outskirts of the village where they lived, so Karp made a radical decision: he gathered his wife Akulina and the two children they had at the time (Savin, nine years old, and Natalia, two) and escaped into the forest. Literally. He walked away as far as he could. Without looking back and with light luggage that included just a handful of seeds, a rudimentary spinning wheel, a couple of jugs to boil water and the clothes they were wearing. Once in the taiga, the family built a cabin with what they had on hand, set up a garden and continued with a life marked by isolation, their beliefs and deprivation. In 1940 the couple had their third son, Dmitry; and four years later the fourth and last daughter, Agafia, was born. Back to history. The Lykovs continued with that life until Osipovich’s helicopter located them in the summer of 1978. It may sound strange, but the family had settled in a particularly inhospitable place. No one saw them before because no one looked there. The marriage moved as he encountered difficulties, moving further and further away from the villages and towns, until settling at a point located more than 240 km of the nearest settlement. Not even the Soviet authorities were aware of the existence of that family. The consequences of that isolation are obvious. For the Lykovs, time, politics, science… stopped dead in 1936. The family did not know that Europe had been shaken by World War II, nor that man had stepped on the Moon in 1969, nor was it aware of the space race, the name Kennedy or the Beatles did not ring a bell… Some family members marveled at seeing a television or items as seemingly simple as matches or a roll of transparent cellophane. Fascinating yes, bucolic no. The Lykovs’ 42 years of isolation were, however, hardly bucolic. Their cabin was built next to a stream and the forest offered them wood, fruit and even game, but the harsh conditions of the taiga subjected them to a constant test. Especially the first years. Agafia even told how towards the end of the 1950s the family faced their peculiar “years of hunger”, during which they had to decide whether to eat the little they harvested or save some of the seeds to grow them the following year. “We were hungry all the time,” he admits. Years later the family suffered a frost … Read more

Getting a manicure while she was on sick leave almost cost her her job. He was saved by a detective who didn’t know how to do his job.

Companies increasingly make use of the services of private detectives to investigate whether their employees really They are on sick leave or they are faking itwhich would be reason enough to a disciplinary dismissal. According to the detectives themselves, the companies that use their services do so because they previously They already have signs that there is fraud, which is why the majority of cases that are investigated agree with the companies that hire them and end up in disciplinary dismissal. However, in some cases, the way that evidence is obtained is the key to the success of the case. This is what happened to the employee of a beauty center in Barcelona. Despite being able to prove that there had been fraud, a sentence The Superior Court of Justice of Catalonia declared the dismissal null and void and forced the company to compensate its employee. Medical leave and dismissal. The employee at the beauty center went to the doctor because of pain in her left hand and back, and they gave her the temporary disability leavewith rest and rehabilitation to recover. While she was still on sick leave, the company began to suspect that perhaps she was not that sick and decided to hire a private detective to check what she was doing outside of work. The detective prepared a report in which he noted that the worker had performed a manicure service for which she had charged 35 euros in cash while she was still on sick leave. With that report as a key piece in its argument, the company fired her via disciplinary dismissal, alleging that she had broken trust and that she was taking advantage of her leave to work on her own. In your dismissal letter you could read: “(…) you summoned, and performed a manicure treatment on, a person who was accompanied by said company (of detectives), at the aforementioned address, and charged this person in cash 35 euros for the service performed. The company has sufficient evidence, images and videos that confirm the regularity of these events.” What the court decides. The worker appealed the dismissal because she understood that it was unfair and was based on evidence obtained illegally. In the first instance, the Social Court No. 1 of Barcelona agreed with the company and declared that the dismissal was appropriate, and assigned the employee to collect 771.15 euros for untaken vacations plus 10% late payment interest. But did not recognize compensation some. The story changed when the case reached the Superior Court of Justice of Catalonia (TSJCAT), when the worker appealed that first sentence. The Social Court reviewed how the detective’s evidence had been obtained and concluded that it was invalid because it had been obtained by inducing the situation. That is to say, something that was already happening had not been observed, but rather the opportunity had been created for the employee to do that manicure. What Detectives Can and Can’t Do. The case puts on the table what private detectives can do when investigating a person on sick leave and what lines they cannot cross. From Sentinel Private Detectivesremember that the law “prohibits them from taking images or evidence of events that occur in the intimate part of people’s lives. The garden is also considered an extension of the home,” so they cannot record there if it is a closed space. The investigation agency points out that their work should focus on “following and observing, without forcing situations,” and that their role is that of “mere observers of facts and behaviors.” Jordi Briñoldirector of Brininvest Detectiveshighlights that its activity is regulated by the Private Security Law and for the Civil Procedure Law, and that in cases of sick leave they can only act in “open spaces.” According to his explanation, “anything that happens in intimate spaces or that has what is called an expectation of privacy, we cannot access there”, and any monitoring must comply with what he calls “the triple judgment of proportionality”, that is, that the evidence is adequate, necessary and that it does not take longer than reasonable. The researcher clarifies that they can carry out actions under pretext (for example, making an appointment in a publicly announced consultation), but “we cannot provoke an unnatural response”, which fits with the idea that the person under investigation cannot be induced to commit the infraction. Why the detective’s evidence is useless. In this case, the court considers that the detective did not limit himself to looking from the outside at what the convalescent employee was doing as his regulations dictate, but that he intervened to make the behavior happen for which she was later punished. Along these lines, the ruling links with the doctrine of the Supreme Court that rejects evidence based on provocation, and remembers that situations cannot be fabricated and then used as an excuse to fire. By removing the detective’s report from the case, the company’s entire argument collapsed, so the Court understands that the true reason for dismissal is that the worker I was on medical leavesomething that Law 15/2022 prohibits using illness as a reason to dismiss a person because it represents discrimination due to illness. For this reason, the Superior Court of Justice of Catalonia declares the dismissal void, orders that the company reinstate the employee, pay her all the salaries that she stopped receiving during the time that the judicial process lasted and pay her 7,501 euros for moral damages, in addition to 600 euros in defense fees.
