Samsung has very different folding ranges. There’s the new Fold8, which is the “foldable for everyone.” There is the Z Fold8 Ultra, the most complete and the most professional in nature; and there is the Galaxy Z Flip8the foldable for younger people who are looking, above all, for practicality and a small device to carry in their pocket or bag. Once again, the Korean company has renewed it to give it a good dose of Android 17improve FlexWindow and lighten it a little.

The Korean company has managed to reduce its thickness and weight to 6.1 mm and 180 grams (6.5 mm and 188 grams in the Z Flip7) while retaining the 6.9-inch screen diagonal. The rest of the specifications are similar to last year’s model, except for the peak brightness, which goes from 2,600 to 3,000 nits. There are no significant changes to the design. Samsung has once again opted for a rear divided into two parts, the upper part being a generous 4.1-inch screen from which to interact with the AI, make calls, view notifications, etc. We have another novelty in the hinge. Samsung has mounted a new technology called Flex Titanium which, roughly speaking, combines a titanium film with a titanium plate in the area of ​​the wrinkle to, on paper, reduce the impact and reduces the visibility of the crease. The theory is that should be noticed and seen less. We will discover the reality when we can analyze it. An engine signed, again, by the house Samsung Galaxy Z Flip8 | Image: Samsung While the Fold brothers incorporate the Snapdragon 8 Gen 5 Elite for Galaxy, the Z Flip8 mounts the Exynos 2600. It is the same strategy that the firm followed last year with the Flip7, which mounted the Exynos 2500. It is a two nanometer chipten cores and a thermal management system that, at least in theory, should stand up to the thermal throttling we experienced in the Flip7. Next to this chip we find 12 gigabytes of RAM and 256 or 512 GB of internal storage, as well as 4,300 mAh battery with 25W fast charging. Same setup as last year, in a nutshell. Samsung still does not dare to make the leap to silicon-carbon and, in terms of performance, the experience should be very similar. Samsung Galaxy Z Flip8 | Image: Samsung A change is found in the operating system, which is now Android 17 with One UI 9. Samsung, by the way, promises seven years of updates. Numbers aside, the Z Flip8 has seen the FlexWindow experience renewed, that is, the capabilities of the external screen, the one we use when it is folded. According to Samsung, FlexWindow “brings apps, information and actions directly to the outer screen,” so in theory it should be possible to use apps like WhatsApp or email from that screen. Now Brief is also displayed on that screen and, by clicking on the side button, it is possible to automate actions through Gemini Intelligence. Two cameras with the focus on creation Samsung Galaxy Z Flip8 | Image: Samsung Few, if any, changes in hardware compared to the last generation. The Flip8 mounts a set of two sensors on the rear (50 MP wide angle with OIS and 12 MP wide angle) and a front sensor on the 10 MP internal screen. We do not have telephoto, as is common in this range. We will use the 10 megapixel camera for video calls and little else, in case this format allows something, it is being able to use the main cameras for selfies (group ones included). Flex Mode allows you to place the folded screen in any position to use it as a tripod, for example; And as a novelty, now the camera is capable of blocking the horizon so that the videos come out well framed even when moving.

After endless leaks and rumors, Samsung has made a new folding format official. Not “new” as such, but different. Because he Samsung Galaxy Z Fold8 It is still a Fold, but now it is much, much more square and, therefore, more panoramic when we open its screen. It is a foldable made, according to Samsung, to adapt to how we see content. This format is usually known as “passport type” and it is something that we have already seen, to a certain extent, in the OPPO Find N (Apple is also expected to adopt it at the end of the year in its much leaked iPhone Fold). The Korean firm thus puts on the table a triad of foldingeach one focused on a different audience and the Fold8 being the most generalist. With the introductions made, let’s get to know them better. Before continuing, we remind you that the members of Xataka Xtra can access discounts, benefits and exclusive opportunities in the Samsung online storein addition to exclusive raffles, a private Discord server and a growing catalog of discounts and advantages on digital services.

The external screen is like that of a regular mobile phone and, when we open it, its size doubles in a screen that borders on the 1:1 format (almost square). The problem is that this format, which is maintained, by the way, in the Fold8 Ultra, is very good for multitasking and productivity, but it involves certain sacrifices in the consumption of multimedia content. The reason? A video on YouTube is usually in 16-18:9, which, on an almost 1:1 screen, means having two huge black bands above and below the content. The passport format partially solves this problem: it sacrifices diagonal on the main screen in exchange for offering a more rectangular folding screen, ideal for watching a video, a movie or playing games in widescreen format. In the case of Samsung, the main screen (the one we use when it is folded) has a 10:16 format. Samsung Galaxy Z Fold8 | Image: Samsung Samsung Galaxy Z Fold8 Ultra | Image: Samsung The folding screen, for its part, has a 4:3 format. Without being completely panoramic, the upper and lower black bands will be a lot, but much smaller. If we put it vertically, we have a size similar to that of a small book, which makes it particularly comfortable for reading or browsing. When it comes to the hinge, Samsung boasts a new technology called Flex Titanium (available in all three folding versions). According to the company, this new hinge combines a titanium alloy film with an “improved” titanium plate that, on paper, helps reinforce the screen support, absorb pressure and reduce crease visibility. This has been one of the most controversial points of foldables historically, the fold and its wrinkle. Speaking of specifications Samsung Galaxy Z Fold8 | Image: Samsung If we talk about inches, the main screen has a 5.5 inch diagonalwhile the folding one amounts to 7.6 inches. In both cases we find a QXGA+ resolution and a variable refresh rate of 1-120 Hz. They are, therefore, fast screens with a more than acceptable resolution. As far as brightness is concerned, 3,000 peak nits, more than enough to use it in full sun and play HDR. One of the things that caught the most attention Galaxy S26 Ultra was the anti-glare and anti-glare screen. For physical and space reasons, Samsung cannot implement this technology in the folding ones (this specific model is 4.5 mm thick when unfolded), but it does claim to have introduced a low-reflective finish that, in theory, should reduce glare when the sun shines in front of it. Maximum power Samsung Galaxy Z Fold 8 | Image: Samsung Samsung has not skimped on power in its new foldable. In fact, in a somewhat complicated context for RAM and storagethe Korean firm has put all its efforts into action. The Galaxy Z Fold 8 has 12 GB of RAM in its versions with 256 or 512 GB of internal storage, and 16 GB in the most powerful version, which is the one with 1 TB capacity. It won’t be for storage, of course. The heart of the terminal is a Snapdragon 8 Elite Gen 5 for Galaxy, or what is the same, a Snapdragon 8 Elite Gen 5 with a lightweight overclock which, on paper, provides extra performance. It will also be responsible for moving some AI tools, namely Now Brief (contextual information), Now Nudge (an assistant for taking actions) and the editing suite. However, Samsung’s approach is hybrid: local+cloud. The battery goes up to 4,800 mAh, which represents an increase of 400 mAh compared … Read more

Many foods and cosmetics have additives that we want to avoid at all costs.

by

Every time we put a packaged potato omelet, hummus or moisturizing cream in the shopping cart, we incorporate dozens of substances into our body that often go unnoticed despite appearing on the label. The preservativesdyes, emulsifiers or sun filters are part of the usual composition of thousands of products that we buy in supermarkets. His presence responds to a legitimate industrial logic: it is necessary to extend the shelf life of a food or stabilize the texture of a cosmetic. The problem is that the regulations that regulate these additives almost always advance behind scientific knowledge. An additive can take decades to be approved and in widespread use before scientific studies force authorities to reopen its file. The European Food Safety Authority (EFSA) periodically reevaluates these compounds, but its way of working requires accumulating solid evidence and sustains years of continuous exposure before any regulatory change. This disconnection does not at all mean that everything permitted is automatically dangerous. In fact, the vast majority of authorized additives are supported by decades of toxicological studies. Even so, it is in consumers’ interest to know which substances have generated the most scientific controversy, in which products they appear most frequently, and which institutions have focused on them. Preservatives that are already under discussion Sodium benzoate (E211) is one of the most commonly used preservatives in packaged potato chips, pickles, sauces and soft drinks. The EFSA has reviewed your security on several occasions, the last in 2016, and has concluded that within the authorized levels it does not raise concerns about genotoxicity (the ability of a substance to damage the genetic material of a cell). It has warned, however, that certain population groups can easily exceed the acceptable daily intake. A quick note before we move forward: part of the controversy about this additive comes from research such as those of Professor Peter Piperfrom the University of Sheffield (United Kingdom), who has documented damage to mitochondrial DNA of cells exposed to sodium benzoate in in vitro assays. EFSA opts for regulatory prudence, while certain academic groups insist on stricter scrutiny Potassium sorbate (E202) follows a similar logic. It frequently appears in hummus, cheeses, yogurts or wines, and acts as an antifungal. The EFSA has reevaluated it in 2015 and again in 2019setting an acceptable daily intake together with sorbic acid of 3 mg per kilo of body weight per day. A study published in In Vitro Toxicology evaluated its genotoxic potential in human lymphocytes cultured in the laboratory, without finding relevant effects at the concentrations tested, which reinforces the official position of the agency. Another relevant note: both preservatives share the same pattern. No reference institution has classified them as carcinogenic, but there is no unanimity regarding their complete long-term safety. The EFSA opts for the regulatory prudencewhile certain academic groups insist on stricter scrutiny, especially in sensitive populations, such as children or people with an aspirin allergy. However, we are interested in putting these figures in context: the real exposure of those who eat packaged potato omelettes several times a week is well below the thresholds at which adverse effects have been observed in the most alarmist studies. The additives most highlighted by science Beyond preservatives, there are other additives that have received much stronger regulatory attention. The clearest case is that of titanium dioxide (E171), a white dye used for decades in candy, chewing gum and some cosmetics. The EFSA concluded in 2021 that its genotoxicity cannot be ruled out, especially due to its ability to accumulate in the body, which has led to the European Union to ban its use as a food additive from 2022. Even so, it is still allowed in cosmetics, such as sunscreens. The antioxidants BHA (butylated hydroxyanisole, E320) and BHT (butylated hydroxytoluene, E321), present in snacks, cereals and some cosmetics, illustrate well the nuances of this type of evaluations. The International Agency for Research on Cancer (IARC) has classified BHA in group 2B as possible carcinogen for humans. BHT, on the other hand, remains in group 3, not classifiable due to insufficient evidence. The International Agency for Research on Cancer has classified BHA in group 2B as a possible human carcinogen. The European Commission has also placed BHA as a priority substance for endocrine disruption, while BHT only arouses similar suspicions in the scientific literature, without an equivalent institutional classification. Long-chain parabens in cosmetics follow a similar path: several of them are banned in the European Union since 2014 by decision of its scientific consumer safety committee. Sodium nitrite (E250), common in sausages and processed meats, closes the list with the best documented case: the IARC classified processed meat as a group 1 carcinogen in 2015, especially due to the formation of nitrosamines when cooked at high temperature. In the following table we summarize these six cases and identify the institution that has indicated the risk of each of them and the effects described in the scientific literature: Additive Where do we find it? Institution that has indicated the risk Described effects E211 (sodium benzoate) Packaged potato omelettes, pickles, sauces, soft drinks EFSA (2016 revision); University of Sheffield Overcoming the IDA in sensitive groups; damage to mitochondrial DNA in in vitro studies E202 (potassium sorbate) Hummus, cheeses, yogurts, wines EFSA (2015 and 2019 revisions) Possible cellular inflammation in animal models E171 (titanium dioxide) Candies, gum, sunscreen EFSA (2021 opinion) Genotoxicity not ruled out; banned as a food additive in the EU from 2022 E320 (BHA) / E321 (BHT) Snacks, cereals, some cosmetics IARC (group 2B for the BHA); European Commission (priority endocrine disruptor for BHA) BHA, possible carcinogen and hormone disruptor; BHT, similar suspicions without equivalent classification Long chain parabens Creams, shampoos, cosmetics Scientific Committee on Consumer Safety (EU) Hormonal disruption; several banned in cosmetics since 2014 E250 (sodium nitrite) Sausages, processed meats IARC (group 1 for processed meat, 2015) Formation of carcinogenic nitrosamines when cooked at high temperatures Image | Kenneth Surillo More information | EFSA | European Union | IARC In Xataka … Read more

“I don’t understand Stallone, I have the impression that he only does it for money”

by

That phrase from Clint Eastwood is not current, but belongs to 2003, to a profile that Lillian Ross wrote about Eastwood for ‘The New Yorker’. Curiously, after that Stallone returned to Rocky, but he did so with a film that was a huge critical and public success. And Eastwood did not return to any of his previous films. That is, a quarter of a century later, the quote is nuanced but it essentially means the same thing. What is it coming for? That “I don’t understand Sylvester Stallone. I have the impression that he only does it for money” was said within Eastwood’s broader reflection on his own career: he was talking about Harry Callahan, about the risk of stagnating artistically, about the need to grow instead of going backwards. At that time, it was not known whether ‘Rocky Balboa’ would end up being a worthy film or a nostalgic wreck. In 2003, filming hadn’t even started. It was cool. Three years later, Stallone wrote, directed and starred in that sixth installment. The critical reaction far exceeded that of its two predecessors: Rotten Tomatoes Today it scores 78% out of 180 reviews, well above the reception that ‘Rocky V’ had in 1990. In commercial terms, ‘Rocky Balboa’ grossed 155.9 million dollars with a budget of 24 million. The installment that recovered Rocky was a very worthy tribute to a classic character. Everyone sins. Eastwood was also not free from the impulse to resurrect characters. He played Harry Callahan five times between 1971 and 1988, until ‘The Blacklist’, the last installment of the saga. When a sixth Callahan was finally ruled out, Warner Bros. did not close the door: in 2004 it considered relaunching the franchise with Dwayne Johnson as a thirty-something detective. The plan died due to Johnson’s own box office failures. Without consequences (relatively). However, Eastwood has remained true to his words: in 2003 he had already abandoned Callahan’s films many years ago and was fully immersed in a career as a complete auteur accepted by Hollywood. Words are always relative, yes, because at the end of the day… what are films like ‘Unforgiven’ if not late sequels to his successes as a protagonist for directors like Leone, where the director wonders what happens when the icons reach an advanced age and all the treasures obtained by clean shooting have come to nothing? What remains The really valuable thing about this statement, which we must remember that the current nonagenarian Eastwood has not uttered, is that it is infinitely nuanced: Rocky returned to one of his classic franchises (and would do so again with ‘John Rambo’, another critical – to a lesser extent, yes – and public success), but it was a more than worthy return. And Eastwood would stay true to his words, but four Dirty Harry sequels are there to remind him that there is no one with a completely irreproachable career. In Xataka | “They were not used to silence”: when Clint Eastwood set foot in Spain for the first time in 1964, he was marked forever

Follow the presentation of the new Samsung foldables live with us

by

If there is a date that marks the halfway point of summer, it is, without a doubt, the Samsung Unpacked. The Korean company brings us together every summer to present its new devices (foldable, it’s no secret where the shots are going) in an event that points out ways. Last year it was in New York, this year it is in London and, as it could not be otherwise, you will be able to follow it live and direct with us. Galaxy Unpacked will take place today, Wednesday, July 22, at 3:00 p.m. Spanish peninsular time. You can follow it live through from our YouTube channelof our live page and from our Instagram profile. The schedules according to regions are as follows: Spain: 15:00 (14:00 in the Canary Islands). Mexico: 7:00 AM Colombia: 8:00 AM. Venezuela and Chile: 9:00 AM. Argentina: 10:00 AM. Live What we hope to see At the beginning of the year, within the framework of MWC, we learned about the Galaxy S26 Ultra and its brothers. The most conventional high-end is already on the table, so now is the time to get to know the new folding ones. Samsung renews its folding devices every year and around this time, aka the Z Fold and Z Flip, as well as smart watches. There have been various leaks that bring winds of change, but the most interesting is the one that came from Samsung itself. The firm published a series of very… suggestive videosin which he made us understand that would launch a new format. A third foldable? The evolution of the Fold or the Flip? We don’t know, but the company has something in the oven. Regarding the watches, it is to be expected that, having been completely renewed last year, in this event the improvement will be somewhat more incremental. We will surely see improvements in the battery, screen or performance. Samsung also has an outstanding debt with your glasses with Android XR and At Google I/O we saw a preview of what they have in the oven, so since dreaming is free… We will clear up doubts in a little while. We remember: the event will be today, July 22, at 3:00 p.m. Spanish peninsular time. In Xataka | Follow Samsung’s Galaxy Unpacked live

What it is and how to prevent it from appearing on your profile

by

Let’s explain to you what that is green dot that begins to appear in WhatsApp contactsand how you can avoid it. It is an indicator that little by little begins to reach some usersand the idea is that it will spread to everyone. We are going to start by explaining to you what the function of this indicator is, so that you understand what it means for it to appear in profiles and what it means for it to appear in yours. Then, we will tell you how to prevent it from happening to you. What is the green dot on a WhatsApp profile The green dot on a contact’s profile photo is a status indicator. It means that the user is active at the time indicated, you have WhatsApp open and are looking at it. The idea of ​​this indicator is that can you know if someone is available before you start writing to him. The green dot is a real-time indicator that will appear when the user is using WhatsApp, and will disappear the moment the user stops being active. The green dot is only shown in the contact information area, when we click on the bubble with their photo to see their information. Inside, it will appear at the bottom of the roundel where the profile photo appears. How to prevent the indicator from appearing At the moment, this green dot has begun to reach Android and iOS, but only in the beta versions of WhatsApp, although it is expected that it will eventually reach all users. If you don’t want it to appear So that others do not know when you are using WhatsApp, you will have to make some changes to the settings. What you have to do is enter the WhatsApp settings and Click on the section Privacy. Once inside, you have to click on Last time time and onlinewhich is the option that appears at the top. This will take you to a screen where you have to change who can see the time you last logged in, and then change who can see when you’re online to match. With this, you will be able to configure who can see your green dot when it reaches everyone, and you can choose Nobody so that no one can or your contacts. There are several options. Here, it’s a bit confusing, because the green dot depends on the option Who can see when I’m online. However, at the moment this cannot be changed independently, so you will have to also change who can see when you last connected.

In Almería they thought they had seen a drug boat. It turned out to be the solar yacht of a Finn who has traveled 6,000 km without refueling

by

The bathers who tried to suffocate the high temperatures of the latest heat waves swimming around Cabo de Gata last sundaythey watched in astonishment the passage of a very unusual boat. It sailed close to the shore, with a lower hull than usual and an extremely quiet engine. It had no mast or visible bridge. Some thought it was a drug boat. Others, directly, in a submarine. It was nothing like that. According to collected Hybrids and Electricswhat was crossing Las Salinas was the Helios 11. When a Civil Guard patrol boat, equally surprised by the appearance of the boat, came to closely inspect that boat on El Zapillo beach, it only found solar panels and batteries. The dream of a Finn who wanted to sail cheap The person that the Civil Guard found on board the boat is Lukas Sjöman, Finnish adventurer, designer and builder of the most sustainable yacht that the Andalusian coasts will see this summer. He built it alone, without a shipyard, in a shed at his house and its price has not exceeded that of a modest car. As Sjöman himself tells in the videos from his YouTube channel, it took about 200 days to have the hull ready, made with a structure of marine plywood and fiberglass. The result is a yacht 11 meters long and 2.4 meters wide, weighing close to 1.5 tons. Inside there is space for some amenities including an electric stove, a light refrigerator and a bathroom with cisternjust enough to live on board, but without the luxuries that millionaires’ yachts usually equip. However, Sjöman’s obsession is not sailing through the most exclusive ports of the Mediterranean. emulating Koru of Jeff Bezos or the superyachts of Arab sheikhs. Their goal was to create a boat that was as sustainable as possible. To achieve this he only had to do one thing: look at the sky. The entire roof of the Helios 11 is covered with solar panels, and as it says on your channelreaches a power close to 6 kW and an expansion to 40 kW is already planned. The system runs on 48 volts and charges the batteries while the boat is underway. The electric motor supported by solar panels allows almost infinite navigation since it does not need to stop to refuel like alternatives with diesel or hybrid engines. Sjöman assures that the boat consumes less while sailing than a domestic blender. On a normal day it travels about 145 miles, about 270 kilometers. In bad weather, the decrease in the charging capacity of its batteries and the greater demand for power during navigation to overcome storms, the figure can drop to 40 miles (about 70 km per day). Helios 11 sailing near the coast A 6,000 kilometer trip to put it to the test And what’s the best way to test that a boat really works? Effectively taking to the sea. Sjöman began a journey of thousands of kilometers to demonstrate that the Helios 11 is a viable alternative to build cheap yachts and with propulsion systems that do not depend on fossil fuels. The Helios 11 route started in Finland and went down rivers and canals, crossing several European countries until reaching the Mediterranean. Sjöman arrived in Ibiza after going through some 5,700 kilometers without refueling. From there he continued his particular Mediterranean cruise approaching the Andalusian coast: Mazarrón, Cabo de Gata and now Almería. Helios 11 anchored in Ibiza The trip has not been perfect. According to collected Supercarblondiewhen he was anchored on the coast of San Carles de la Rápita (Tarragona) his auxiliary boat was stolen. So he had to build another one to continue because the Helios 11 cannot anchor on shallow beaches or in small docks to resupply with supplies, so without the boat the Finn was left “incommunicado” on board. Solar energy solves fuel. It does not solve the logistics or unforeseen events of sailing alone. A clean alternative to the most polluting yachts Current superyachts take more into account comfort and nautical luxury than the emissions from their engines. The few hybrid alternatives that alternate electric and diesel engines are aimed at obtaining quieter navigation and anchoring, not to reduce emissions. According to the report ‘Carbon emissions inequality kills Elaborated by Oxfam International, the yachts of the richest billionaires generated in a single year a carbon footprint which is equivalent to 860 years of emissions from the average person. The problem with these boats is that, as the seized superyachts to the Russian millionaires for the war in Ukraine, they must keep their engines running to feed the air conditioning that prevents the noble materials inside from deteriorating, generating fuel consumption of several thousand dollars a day.

An AI model did not have access to the internet. So he thought it was better to have it and decided to hack something along the way

by

Last week, OpenAI I was evaluating the offensive capabilities of two of its most advanced models. On the one hand, GPT-5.6 Sol, publicly available. On the other, a second model not yet presented and which in fact is described as superior to the first. It was about measuring their capabilities in the field of cybersecurity, and although the testing environment was theoretically airtight and isolated, both models managed to connect to the internet and hack a very popular AI models and testing platform, Hugging Face. what has happened. Both models were being evaluated using ExploitGyma cybersecurity benchmark developed by researchers at the University of California at Berkeley. The goal is to try to find real vulnerabilities in real software. Instead of searching for them on their own, the models detected that the (unspecified) packet logging cache proxy, the only component with limited external access, had a flaw that they could exploit. A study by the AI ​​Security Institute reveals the advances of the latest OpenAI and Anthropic models in cybersecurity. Hello, internet connection. The models did not have internet access, but they exploited that vulnerability to achieve it. Once this was done, they assumed that Hugging Face, the reference platform for models and data sets (datasets) of AI, probably had data on ExploitGym that would allow them to overcome the requested challenge. Hack Hugging Face. So they searched, found and exploited several attack vectors at once, including both stolen credentials and zero-day vulnerabilities. With all this, they managed to access Hugging Face’s production database (that is, the one used publicly on their website), and from there they achieved the solutions to the benchmark. GLM-5.2 to the rescue. The OpenAI security team detected anomalous activity, but Hugging Face I had already detected it a few days ago without knowing what was happening. The curious thing is that to respond to that attack they first tried to use proprietary US AI models to contain them. Those models were blocked by automatic security filters, and Hugging Face turned to the GLM-5.2, the surprising open model from Z.ai that was launched a few weeks ago. The chat with all the details. Adrien Carreira, Infrastructure Manager at Hugging Face, I summed it up in X: “We fight with open models, in the open. AI security will not be solved by a single company acting in secret. Open source puts these tools in the hands of all defenders.” This expert also shared the conversations that they maintained with the AI ​​model to address the problem. Brute force works again. At OpenAI indicated that this was an unprecedented (involuntary) milestone, although some cybersecurity experts reduced the relevance of what happened. “This is not an AI problem. It is negligence on a forty-year-old standard,” explained David Ottenheimer. However, as with Mythos, what this event demonstrates is that AI can apply brute force and analyze possible vulnerabilities (and combine them) in a way that human researchers could not due to lack of time. A fundamental problem. OpenAI acknowledges that the deployment filters that would have blocked the model’s behavior were intentionally disabled because the assessment was intended to measure vulnerabilities. Dierdre Mulligan, professor at Berkeley, indicated that “it seems to me that OpenAI did not properly create the sandbox for the testing environment.” It was not clear to her that passing a test would outweigh the potential damage that an AI model could cause if it “escaped” and gained access to the internet. The end matters, not the means. The models did not have the objective of hacking Hugging Face: that was only a means to achieve their ultimate goal, which was to beat the ExploitGym benchmark. Everything they did along the way—finding the vulnerability that gave them access to the internet, hacking Hugging Face’s database—was simply part of their plan to pass the proposed test. What have each other learned?. Following the incident, OpenAI indicated that they are implementing stricter controls in the configuration of their infrastructure, in addition to collaborating with the developers of the affected component and with Hugging Face to improve their defenses. They have also promised improve “alignment” of their models and the monitoring tasks during this type of tests.

The lynx in Spain is growing at such a speed that it has appeared in an unexpected place: Euskadi

by

An Alava rancher checked his photo-trapping camera last December. He was looking for genets, badgers or wild cats on the plot he has in Campezo. And he found biological gold. The unmistakable brushed ears and sideburns make it clear: the video in question It shows for a few seconds the presence of a lynx in the middle of the night. A tourist from the south. The Hontza Natura Elkartea association spread the image and the environmentalist offices raised their eyebrows: something like this had not happened in more than a hundred years. The boreal lynx inhabited the Aitzkorri-Aratz mountain ranges, the Gorbea massif or Valdegovía at the beginning of the twentieth century. But this is different, it is a Lynx pardinuspure and simple Iberian lynx. The same one that is being tried to reintroduce in the Valencian Community. And he wears a radio transmitter collar. Apparently, it comes directly from the south of the Iberian Peninsula, crossing half of Spain without a train ticket – it is not in vain that they can travel up to twenty-five kilometers a day. Hence, this presence in Álava marks a brutal biological milestone… and opens a crack in the debate on the recovery of wild fauna. Avoiding extinction. It was close and literally. There were less than one hundred copies left at the beginning of the 2000s and today they exceed 2,700. The Ministry for the Ecological Transition (MITECO) he stuck out his chest before Europe with their official censuses, consisting of specimens in Zaragoza, Palencia or Cuenca. The WWF Spain celebrated also the success of the Iberlince program. The specimens released in Andalusia, Castilla-La Mancha and Extremadura have managed to settle. And the natural expansion towards Aragon or the northern plateau demonstrates feline adaptability. However, this Disney story with a happy ending should also be read from rural sociology. Because this feline depends almost exclusively on the wild rabbit. 90% of your diet. Diseases, such as myxomatosis or viral hemorrhagic fever decimated its population. 212 died from accidents. And, when hunger strikes, the animal will seek new territories. That’s where the real problem begins. At some point, people will target the lynx. Beautiful and problematic. PACMA warned of the risk. Animal activists denounce deaths due to vehicles being run over and demand urgent and effective wildlife crossings. Ecologists in Action pointed out another enemy: illegal and poaching. Snares, poison and shooting kill dozens of cats a year. Artemisan Foundation, voice of the hunting sector, defended another position: that hunters have absolute control over predation in their reserves. When rabbits are scarce, lynx compete directly with shotguns. The school story has clothed the lynx with sympathy. He enjoys good press, with that amber look that is touching. Let’s take as an example the hatred suffered by the wolf or the brown bear. The demonstrations by ranchers against the wolf have paralyzed roads in Cantabria—although the story changes little by little–. The bear, in the Pyrenees and the Cantabrian mountain range, falls even worse. After all, the lynx weighs less than fifteen kilos, is elusive and rarely attacks larger livestock or calves, settling for partridges, rabbits and, if lucky, some absent-minded chicken. A close precedent. The wild boar is the best example in Spain. A couple of decades ago, seeing a wild boar brightened the day of a Sunday hiker. Today they affect crops on the plateau and cause fatal accidents on secondary roads, becoming an urban drama. The Generalitat of Catalonia declared constant hunting emergencies due to overpopulation. So the animal went from being a majestic pig to an official and destructive pest. Raids have been carried out for five years. Germany underwent an identical metamorphosis with the gray wolf. Politicians celebrated its return as an unprecedented ecological triumph and Berlin urbanites designed welcoming campaigns, until the shepherds of Lower Saxony suffered the direct consequences. German Green and Conservative Parties Now Openly Debating Lethal Hunting Quotas. Canada saw how the populations of pumas and black bears They multiplied near high-income residential areas, where cities like Vancouver or Banff celebrate their mystical connection with nature, until they began attacking pets, scaring children in public parks and sneaking into gardens. The shadow of the Iberian lynx. Seeing how it is expanding, with Álava as the tip of the spear, the question is whether beyond the Gorbea massif they will begin to sneak into private farms with greater frequency, whether they will hunt poultry and attack small rabbit farms. Hontza Natura Elkartea documented the discovery but Euskadi lacks an official reintroduction plan for this species. And we want wild and vibrant nature, yes, but away from our garage, without personal risks.

It’s another excuse to charge more.

You organize your vacation, book a hotel, and the notice is usually always the same: entry from 3 p.m.. For those who carry many suitcases and arrive early, this causes more than one headache, and hotels know this well. In fact, they are cashing in on it. Hotel hours change. Before 2020, it was normal for check-in time (check-in) was at 2:00 p.m. and the departure time (check out) was at 12:00. Since the reopening of hotels after the pandemic, the chains have been pushing these schedules towards others that of course make your operation easier. Nowadays it is common to find that the check-in It cannot be done before 15:00 and the check out It’s at 11:00 or 12:00. The “kellys” have a very valid point.. There is a reasonable argument for this change: as a Hotusa spokesperson explains in El PaísThese schedules ensure that cleaning teams have enough time to leave rooms spotless. Those who do this cleaning, the so-called kellys, confirm this, and clarify that those four hours give them room for maneuver because the average is that each worker cleans between 20 and 30 rooms a day. That is totally logical, but hotels are also taking advantage of the circumstance. Welcome to the “Early check-in“and to”Late check-out“. Although no hotel chain explicitly recognizes it, a Barceló spokesperson did admit that this opens a new avenue of business. In recent times the options “early check-in” and “late check-out” in various hotel chains so that customers can enter between one and two hours before and leave between one and two hours later. These options, of course, have an extra cost that means that hotels can in turn have an additional source of income that they did not have before. If you are a loyal customer, you can enter earlier and leave later. Other chains offer these extended hours to members of their loyalty programs. Marriott allows your clients of the Gold Elite program leave two hours later with a minimum of 25 nights a year. Those in the Platinum Elite program have 50 nights per year. Hyatt, Hotusa and Melia they do the same. The pattern is identical in all cases: flexible access to schedules is not a right of the guest, but a privilege of the loyal customer. The trap of loyalty services. Hotel chains’ points programs operate on a disturbing premise: if you concentrate all your stays in a single hotel brand, you recover services that were previously standard for any customer. Those early check-in and late check-out They are the clearest example, but the list includes other benefits such as room upgrades, free breakfasts, access to executive lounges or added connectivity services. What was once courtesy is now a reward for your loyalty. A loyalty that, yes, you pay while you lose some ability to choose. A fantastic idea except for the occasional tourist. The chains consulted in the text agree on the same idea: these changes make it possible to improve the experience of frequent customers, and at the same time make possible more efficient management of resources. What they don’t say is that the model has a clear winner, and it’s not the occasional traveler. The tourist who travels two weeks a year, arrives at his destination on an early morning flight and books through a conventional tour operator is doomed. Pay a higher rate, do not accumulate redeemable points and wait hours in the lobby or you are forced to pay extra.
