the top, the young man and the great rival of the folding iPhone

by

Samsung has introduced its new Galaxy Z series: Fold8, Fold8 Ultra and Flip8. It is not a hierarchy from high-end to low-end, but three different ways of understanding a foldable, each one aimed at a specific type of user. Fold8 For those who want a foldable designed above all for consuming content: its screen is adapted to video, reading and networks, with a lighter body than the rest of the range. Fold8 Ultra for those who prioritize productivity and a top camera. It is the thinnest foldable launched by Samsung and its 8-inch screen allows you to work on several applications at the same time. Flip8 for those who prioritize being able to carry their cell phone in their pocket, no matter how small it is, and the lifestyle. Also for those who prefer not to open their phone if it is not necessary: ​​its external screen has been redesigned to be able to do more with it and not have to unfold it. 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. You can join the community for only 30 euros per year. In detail. The difference between Fold8 and Fold8 Ultra is not only in range but in screen proportions. And therein lies the key to who each one is for. Samsung Galaxy Z Fold8. Image: Samsung. The Fold8 It has a 4:3 interior screen, more square than elongated. Samsung explains that this format imitates the proportions of a magazine or a book: it is comfortable for reading, watching vertical or horizontal video and browsing, but it is not designed to have two or three apps open at the same time. On the outside, its 10:16 screen is the narrowest in the range, ideal for using it folded like a normal mobile phone. At 201 grams it is the lightest Fold, and it has a 50 MP dual camera, enough for everyday use, although it is not the best. It is, in short, a foldable built to consume content comfortably, not to work on it. And it is, coincidentally, the same form factor that has been leaking for months on Apple’s first foldablescheduled for a month and a half. Samsung doesn’t say it like that, but it has come first with a design that so far no one else has released in that exact format. At least in Spain. Because Oppo had its Find Nbut not in our market. Samsung Galaxy Z Fold8 Ultra. Image: Samsung. The Fold8 Ultra reverses that logic. Its interior screen grows to 8 inches, large enough to divide it into several windows and work with two or three applications at the same time, something that the normal Fold8 does not offer with the same comfort due to its more elongated shape. In exchange, it weighs more, 215 grams, and includes a 5,000 mAh battery and an expanded graphite cooling system to withstand long workloads: editing, multitasking, content creation… Its main camera jumps to 200 MP with HDR, designed for those who need the best possible results. It is the same screen size as a Fold8, but with the hardware aimed at producing instead of consuming. Samsung Galaxy Z Flip8. Image: Samsung. The Flip8 plays in another league different: It does not compete in interior screen size with either of the two, because its beauty lies in folding up to fit in a pocket. At 6.1 mm thick, it is the thinnest Flip that Samsung has ever launched, and its differentiator is not the main screen but the exterior FlexWindow, now converted into an interface with its own AI: it allows you to respond, consult information or launch actions without opening the mobile. It is the foldable designed for those who use their cell phone in short bursts throughout the day, not in long sessions. Yes, but. The Fold8 is not the flagship. That role is maintained by the Ultra: more battery, better camera, and larger screen. Anyone looking for “the most powerful folding Samsung” should not look at the passport format model, but at the Ultra. Samsung takes a risk here that it does not usually take: launching three folding devices at the same time means that they compete with each other for the same buyer, not only with the rest of the market. And now what. The three models are already in the reservation period in some markets. Samsung has not confirmed prices yet. Each purchase will include six free months of Google AI Prowith 5 TB of storage.

you need two cable cars, a cable car and to climb to the top of a mountain

by

When someone wants to buy a Rolex, the most common thing would be to go to a central shopping street in any big city in the world and enter one of the exclusive watch stores that abound in these types of commercial hubs. However, to enter the latest boutique that the Swiss watch brand has opened you will need more than just taking a taxi to the center: you will need to grab a backpack, hiking boots and prepare to climb to a peak in the Swiss Alps. As and how I collected watchprothe Swiss brand has opened the highest boutique in the world: at 3,020 meters above sea level, at the top of the Mount Titlisin the Swiss Alps. Yeah, In Switzerland you can buy a Rolex on one of the highest peaks of the country. Getting to the place in question is not easy: you have to take a train, go up on two cable cars and, as the last stretch, ride the Titlis Rotairthe world’s first rotating gondola, opened in 1992. And then, of course, you can buy your Rolex, although in all likelihood you won’t be able to take it home. Who said that to buy a Rolex you only needed to have money? Buying a high-end watch has never been so literal Mount Titlis rises 3,238 meters above sea level, in central Switzerland, about 40 km south of Lucerne. Access from Engelberg includes several stages by cable car and two cable cars, according to the information itself. Titlis website. The final section takes place on the Rotair, a journey that lasts five minutes and rotates 360 degrees on the more than 5,000-year-old glacier, offering views at more than 3,000 meters above sea level. The Tallest Rolex boutique in the world It opened in June 2026, shortly after the inauguration of the Titlis Tower, a peculiar 76-meter-high skyscraper made of concrete, steel and glass that has defied the laws of logistics and Alpine engineering. Titlis Tower at the top of the Swiss Alps The renovation of this old telecommunications tower is part of a million-dollar project to convert the top of Titlis into a tourist center by 2029, when the new area linked to the ski resort of Titlis-Engelberg. Rolex has been one of the first luxury brands to settle there. The top of Titlis already received almost a million views annually before the opening of the tower, with tourists from India, Germany and the United States as the main international groups. The Rolex store is located inside the Titlis Tower, a building that signed Herzog & de Meuronthe Swiss studio that won the Pritzker Prize in 2001 and that has to its credit the design of the Tate Modern Londonhe Allianz Arena of Munich or the Olympic Stadium in Beijing, also known as “the bird’s nest“because of its shape. You get to the top and you leave with a waiting list Going from a mountain trek to the luxurious interior of a luxury watch boutique is a contrast that accentuates the dystopian experience of buy a rolex on top of a mountain. The store has the usual Rolex language: marble, wood, natural stone and well-placed sofas to enjoy the views while your checking account takes the hit. The store is managed by Bucherer, the watch sales chain that Rolex acquired in 2023 following the decision of its owner Jörg G. Bucherer, without direct heirs, to sell the business. The operation was formalized in 2024, after approval by the competition authorities. Bucherer operates more than 100 stores, but the one at the top of Titlis is by far the most unusual. Views from the Rolex store at 3,200 meters above sea level However, and here is the big final twist of this alpine adventure, after having traveled by train, two cable cars, the rotating gondola and climbed the 3,020 meters of altitude of this mountain, the shopping experience It is the same as in any other Rolex boutique in the world and it is very likely that the model you are looking for is not available. So you will go home without your watch. Rolex does not manage official waiting lists, but rather delegates availability to each dealer. That makes availability uneven depending on the model and design you choose. What is constant is that the most sought after models continue to be hard to getalthough the pressure starts to loosen in some markets from 2025. Although it may seem that opening a tent on a peak in the Alps It is more of a publicity stunt than something profitable, for a company whose image was forged on expeditions to the Himalayas and the conquest of Everesthaving a store above the clouds fits better than it seems.

60 million views and 6 weeks in the top 10

by

The first season of the live-action adaptation of ‘Avatar: The Last Airbender‘ was met with divided opinions from fans, who in some cases accused it of diluting what made the animated original great. Even so, 61.2 million households watched itwhich led to Netflix to renew the series for two more seasons before its first week on the air ended. Today the second season arrives, and it brings exactly what fans of the original anime wanted: Toph. The truth is that in its first season, the series more than met Netflix’s expectations, after the success of ‘One Piece’: it registered 18.5 million views in its first week. ‘Avatar’ surpassed it with 21.2 million homes and 153.4 million hours watched, reaching that total of 61.2 million homes. It topped the Top 10 in 92 countries for eleven consecutive days. The second season adapts the “Earth Book” from the animated original, the arc considered by many followers to be the most complex of the series. It consists of seven episodes, one less than the first season, although the producers have indicated that the chapters are longer. Two years after that, the narrative axis is the city of Ba Sing Se, capital of the Earth Kingdom. The most anticipated signing this season is Miya Cech as Toph Beifong, the blind teacher who becomes Aang’s instructor. She was selected from 6,000 candidates and worked with a visual impairment consultant to represent Toph’s sensory connection to the terrain around her. Everything is ready for a return in which the waters seem to have calmed down after some very turbulent first steps. Michael Dante DiMartino and Bryan Konietzko, creators of the animated series, joined the project in 2018 as executive producers and showrunners. Two years later, they announced their departure, saying they could not control the creative direction of the series. They were succeeded by Albert Kim first and Christine Boylan and Jabbar Raisani for the second season. Raisani and Boylan are responsible for seasons two and three, recorded consecutively between September 2024 and November 2025.

What is the blue dot at the top of your Android mobile

by

Let’s tell you what is the blue dot that will soon start to appear on the screen of your Android mobile. This is a new indicator similar to the green and orange dot which already appears on many devices, a privacy indicator that tells you when an app is accessing specific sensitive data on your mobile. We are going to start the article by explaining what this blue dot on the mobile screen means, and the fact that it can appear or disappear from it. Then, we will tell you what you should do in the event that this point appears for no apparent reason, an indicator that an app could be doing something behind your back. What does the blue dot on your phone’s status bar mean? The blue dot in the status bar that appears at the top right of the screen of an Android mobile means that an app is accessing your location. Every time your phone is sending your location the dot will appear, and then it will disappear when it stops doing so. This is a method with which your mobile phone tells you the exact moment in which the location permission is being used. The goal is that apps do not use your location without you knowing itand that you can detect bad behavior in applications. Therefore, with this three types of colored dots will appear on your mobile screen: green dot: Indicates that an application is using your mobile camera. orange dot: Indicates that an application is using your mobile microphone. blue dot: Indicates that an application is using your mobile location. At the moment, this indicator has already begun to arrive to some Google Pixel phones, such as the Google Pixel 10a. However, it is expected to become a standard indicator that will also soon begin to reach other Android phones from brands such as Samsung, Xiaomi, and others. What to do if this point appears for no apparent reason This blue indicator will appear whenever your phone is using location data. If it appears when you do not have an application open It is because someone is accessing them in the background. If you see that your location is being used but you don’t know what application it may be, it is best to check your location access permissions in the settings of your Android mobile. To do this, go to Settings and go to the section Privacy and security. Once inside, click on Privacy Settingsand inside access the section Permissions manager. This will take you to a list with all the permissions on your mobile, and you must click on the permission Location. By doing this, you will go to a list where you will see all apps that have permission to access your locationboth those that do it at all times and those that can only be accessed while you use them. Here, you can review which applications you are giving this access to, and you can revoke it from any that you consider should not have it.

Would you let them clean your house for free in exchange for filming it from top to bottom? This startup thinks you’ll say yes

by

Your floor like the jets of gold down your face. In principle, this is how good the proposal sounds. shifta service launched in New York that offers comprehensive home cleaning services. Is it perhaps an NGO? Well no, the company does not charge in currency: an operator enters your house to the kitchen (literally) wearing a recording device that allows him to record his movements on video during the entire cleaning session. That video is then converted into training data for robotics and AI. In other words, the user does not pay with money, they pay with data. This exchange is not new by any means, but the saying “if something is free it is because the product is you” has gone from the screens to the most intimate part: your home. Clean your house and pay with your privacy. The mechanism is direct: a service in exchange for data. According to says Harry KilbergShift’s US CEO on his X/Twitter profile, upon your request, the company sends a “verified” operator to clean up and leave. In exchange, it records the cleaning so that robotics companies have access to those movements and, through training, their units can replicate it. In other words, there is a camera monitoring the movements of the operator and in the background, your dirt, the rooms of your house and each and every one of your things that are visible and can be cleaned. The Service FAQ They detail that the recordings are anonymized before being processed and that they blur any information that could identify you. But of course, “anonymized” is not the same as private: There is research that shows that anonymized data is not so anonymized: it can be re-identified quite often when crossed with other sources. And in a house it is even easier: the distribution of space, objects and your routines They make up a unique image of you, your tastes and your habits.. Anonymizing the video does not eliminate that trace, it only hides it in plain sight. How does it work? shift Why is it important. Because the home has historically been the last stronghold of privacy. You may post photos of yourself having brunch on a terrace in Malasaña, but you might think twice before sharing your breakfast muffin in a cup of Mr. Wonderful with a cosque while wearing a threadbare robe with cheese stains from last night’s pizza. It is true that the fever of connected devices and wearables had reduced that redoubt, but Shift goes one step further: it is an active recording of the interior of private homes made by an outsider and that is expressly dedicated to a market. The company accumulates a huge amount of information about you: how you live, what you have, how you behave in private. In return, you have a vague idea of ​​what he does with your data and you don’t know who he sells it to or how he uses it. It is, in short, an imbalance of information from which there is no turning back. On the other hand and as Shift explains, home cleaning and its automation towards an eventual service carried out by robots is just the beginning: there will be an expansion towards home maintenance, repairs and errands. If the model scales, the volume of private indoor data that would be generated would be enormous, an asset as valuable as it is sensitive. Context. The closest examples of the digital attention economy are well known: Google and Facebook have built their respective empires by offering free services in exchange for behavioral data, only Shift takes it to the physical world, one step further, more intimate and more complex to revoke. Its business model is part of the trend of training robots by knowing how humans move and how we perform in real spaces, something that companies such as Figure AI either Physical Intelligence (Pi) because in reality, we are living in a race to obtain this information. How they do it. Its operation consists of three steps: verifying the operators, recording during service and anonymization before processing. The Shift project begins in New York and on its website it announces its presence in 15 countries (although it seems that it is more of a promise of deployment than a reality). Its beginnings are common in these times of social networks and virality: respond to the publication with “Shift” to receive early access and gain visibility. Of course, what is not publicly explained is the technical architecture behind data anonymization, which third parties receive the data, the security standards applied to the devices carried by the operators or the audit mechanisms (if they use them). Yes, but. In fact, as explained it would not meet the standards of the GDPR European (article 5 refers to the fact that any processing of personal data must be transparent, limited and justified). One of Shift’s slogans is: “You get a spotless apartment. We get training data. Everyone wins.” One thing must be given to the startup: it is honest from the beginning when it comes to making it clear that the recorded data is going to be commercialized. How many conditions of use of applications that we use daily are less clear when it comes to talking about the destination of the data. Of course, informed consent is weak precisely because of the opaqueness behind it and because of an obvious reality: a recording of your home is not a tweet and the consequences of sharing it are much more serious.

The manufacturers promised them happy with “Ultra” phones up to the top of specs. The RAM crisis has other plans for them

by

Being an Ultra is not usually the best, unless you are a mobile phone. For years, manufacturers have been throwing darts at each other, launching models designed by and to demonstrate muscle. There was a manufacturer who threw the first stone, and the rest began to follow him. Today, with the component crisis that AI is causing, are in danger. The beginning of everything. The first “Ultra” mobile phone on the market was the Samsung Galaxy S20 Ultra. The company did a fairly marketing exercise: 108 megapixel camera, 100x zoom… everything in a big way. Was it the best Galaxy to date? Yes. Was it a strategy to set a new industry standard through an even more striking surname? Also. China wakes up. China was quick to react to Samsung’s message. Xiaomi responded with the Xiaomi Mi 10 Ultraa phone that debuted 120W fast charging (absolute nonsense a few years ago), 120x zoom to surpass Samsung, and even a transparent finish to show off its hardware. It was the first Chinese mobile phone to fully enter the war: “we are going to put absolutely everything we can into a mobile phone, whether it is useful or not.” And from then on, the party began. Raised to the absurd. The war to launch increasingly powerful Ultra models is beginning to move away from its original objective. Samsung launched a first model with oversized specs, but with a certain commercial purpose. Manufacturers like Vivo launch phones like the 300Ultra They are sold directly in a kit that makes their price practically unattainable, and some of the direct rivals of Samsung and Apple surpass Western brands in price. Chinese manufacturers do not want to sell them, they want to continue demonstrating technological leadership. in check. As pointed out Ice Universethe flagship Ultra is in danger, and some of the big Chinese brands are considering pausing this product line. The Chinese Ultra is not born to sell in volume, and the Pro models or series number (Xiaomi 17simply) are those who are born to sell, even in China. The increase in costs of components such as internal memory or RAM makes launching Ultra models even more complicated, unless the manufacturer wants to raise the price to the absurd. Yes, but. Despite Ice’s predictions, it seems unlikely that the RAM crisis could completely knock down the Ultra models. Manufacturers have been betting for years on a strategy that allows them to reduce costs and continue advancing in their product line: launching exactly the same mobile year after year, but with some additional touches. This allows you to contain costs, recycle parts and reduce R&D spending, while maintaining memory configurations that cannot be reversed. Be that as it may, it seems inevitable that the RAM crisis will completely affect the mobile market, and that in 2027 we will see progress in dribs and drabs.

mount a solar panel on top

by

Aragón is one of the autonomous communities of “energy Spain” and its capital is positioning itself as one of the leading European cities in the urban energy transition. Within your strategy “Zaragoza Smart and Climate Neutral City“, the capital of the Ebro has just start the works to increase its photovoltaic park within the city without altering the available space for other infrastructure. As? Installing photovoltaic canopies in four public parking lots. Parking lots converted into solar parks. The facilities are distributed in four locations: the Miguel Servet parking lots (780.64 kWp), Pignatelli (460.53 kWp), Parque de Oriente (963.9 kWp) and the Macanaz discretionary bus parking lot (279.65 kWp), reaching a total installed power of 2,484.72 kWp. In total, there will be 4,176 solar modules to cover 10,816 square meters of canopies and will produce 3,638.5 MWh per year, which is approximately equivalent to the consumption of a thousand average homes. according to city council data. The structures are not simple panel supports, but canopies designed to integrate into current urban aesthetics, so that they offer shade and protection to vehicles. In addition, of the 651 spaces that will be protected under a photovoltaic cover, 40 will incorporate charging points for electric vehicles. Why is it important. As explains the Renewable Foundationthe parking lots – photovoltaic parks are three in one: they provide shade for vehicles, provide “clean” electricity to electric car charging points and also make energy from renewable sources available for self-consumption or supply. The third point is especially interesting: there will be homes close to the parking lots (within a 5 km radius) that will be able to benefit from this energy without having to install panels in their buildings and all that this entails in terms of investment or bureaucracy. Furthermore, consuming energy where it is produced minimizes transportation and distribution losses. At an institutional level, the council will reduce its energy bill and advance its climate neutrality objectives for 2030. Architecturally, the relevance of this project lies in the efficiency of land use, since it uses existing infrastructure that is already sealed by asphalt, which prevents the degradation of natural or agricultural land. Context. The project is part of the European Commission’s mission of “100 Smart and Climate Neutral Cities by 2030” of which Zaragoza is a member, which forces the capital city to accelerate its energy efficiency and sustainable mobility policies. Zaragoza already has successful solar projects under its belt, such as host the first “solar neighborhood”“of the Spanish state. On the other hand, the Spanish regulatory framework (Royal Decree 244/2019) has facilitated the expansion of collective self-consumption through a simplified compensation mechanism for the energy produced and not consumed instantly by small self-consumers, which makes it technically and legally viable that, for example, the solar parking in Macanaz can provide energy to nearby schools or homes. The regulations allow an installation of up to 5 MW with consumption points up to 5 km away, which gives more breadth and flexibility. This legal certainty has allowed Zaragoza to be one of the most ambitious cities in the deployment of urban photovoltaics in Spain. chow they do it. Through a public-private collaboration where the city only provides the land. The project was awarded in January 2025 to Repsolwhich executes it through Solar360, a joint venture of the energy company and Telefónica Spain specialized in photovoltaic self-consumption. The investment is 5.66 million euros and is borne by the company: the City Council does not pay anything for the installation or maintenance. In exchange, Repsol operates the service for 25 years and pays the council a fixed fee of 6,000 euros per year for each of the four parking lots, plus a percentage of the energy generated in kind: 10% in three of the lots and 4% in the fourth. Yes, but. The work requires the felling of about 38 trees in the first two lots, which will be compensated with 55 new 16/18 caliber trees (not a seedling, but not an adult tree either) and a contribution of 23,990 euros. The problem is that they do not replace an adult tree and its functions (shade, water regulation, minimizing the heat island effect), something for which they will need decades. On the other hand, according to the Renewable Foundationthis type of installation is amortized over a period of four to eight years. With a 25-year concession, Repsol will recover its investment in less than a third of the period granted, which raises reasonable questions about whether the fee received by the City Council is proportional to the profit the company obtains. When the project is operational and we know real production data and participating homes, we will know the answer.

James Webb has had to investigate whether he was born “from the top down” or “from the bottom up”

by

29 Cygni b is a huge celestial object, with a mass equal to 15 times the mass of Jupiter. Apparently it is a planet, but that mass could place it as a star. For example, a brown dwarf. Therefore, a team of astronomers has used the James Webb to analyze its origin, further refining the concept of the formation of stars and planets. A question of metals. The authors of the study, who it was just publishedhave used the NIRCam camera on the James Webb Space Telescope to take photographs of this planet. This instrument allows high-resolution images and spectroscopy measurements to be taken, with which the composition of the atmospheres of stars and planets can be studied, taking into account how they reflect light. Thanks to this, it has been seen that 29 Cygni b is very enriched in metals compared to the star around which it is located. Specifically, it has an amount of metals equivalent to 150 Earths. This is compatible with the accretion of a large amount of metal-laden solids into a protoplanetary disk. It is then confirmed that it is a planet, but a planet very unusual. Planet or star? That’s the question. Planet formation takes place in a bottom-up process. In a disk of gas and dust, known as a protoplanetary disk, dust particles collide to form small fragments of rock and ice, which continue to clump together and grow until they form a planet. It is a process called accretion. The largest ones, in addition, in this process capture gas, which is why they later become gas giants. On the other hand, stars form from top to bottom. A gas cloud fragments and each fragment collapses under its own gravity, becoming smaller and denser. From paradox to paradox. This definition could lead us to think that planets are larger than stars. After all, planets go from less to more and stars from more to less. However, that is not true. Stars form when huge clouds of gas collapse, so they are still very massive. So much so that nuclear fusion can occur in them due to the high conditions of pressure and temperature. On the planets, although there is a growth from less to more, it is not so great. The problem is that with planets as immense as 29 Cygni b there are doubts about the formation from less to more. It would seem that they were also formed by a fragmentation process in protoplanetary disks. As explained by the European Space Agency in a statementis something that “could explain why some very massive objects are found billions of kilometers from their host stars, in regions where the protoplanetary disk should have been too weak for accretion to occur.” That’s just what happens with 29 Cyni b. It has an enormous mass and is 2,400 kilometers from its star. What James Webb teaches us. The fact that 29 Cygni b is so rich in metals indicates that it must have been formed by an accretion process, in which it accumulated more and more. In fact, heIt is normal for a planet to have many metals in proportion to its starwhich happens in the system in which 29 Cygni b is located. In short, it is shown that much larger planets than we thought can be formed by accretion, without having to resort to a top-down process. And now what? 29 Cygni b has been the first of the four objects that will be studied by James Webb. All of them have a mass between 1 and 15 times that of Jupiter and are at least 1.5 billion kilometers from their star. This indicates that they are all in that dilemma of being huge planets or another star. Cataloging them into one of the two groups can help us understand much better the process by which the largest planets are formed. Image | NASA, ESA, CSA, J.
