step by step creating the bot and adding artificial intelligence to it

by

Let’s explain to you how to create your own AI bot on Telegramso you can interact with it at any time. In this way, the bot will be yours and you can put the model of artificial intelligence whatever you want, whether Gemini, ChatGPT, Claude or whatever. To carry out this task we are going to use two services. First we will use BotFather of Telegram to create the bot, and then we will use the service Make to create a workflow or workflow that adds an AI, which in the case of our step by step will be Gemini, but you can use any other. But before we start, I must remind you that even if the bot is yours, everything you write will be sent to the Make servers to process the workflow and the AI ​​you choose. Therefore, be careful with writing personal details that may violate your security or privacy, because you will be giving them to these two companies. First you must create the bot The first thing you have to do is create a bot on Telegram using BotFather. To do this, write a message to the bot @BotFather and write to you as if you were a new user. Type the command /newbot to create a new bot, to which you have to give a name to identify yourself and a unique username to access the bot whenever you want. When you do it, it will give you two things, first the username and address of your bot to access it, and second an access token with various figures and letters. You have to save this token to use later. In the message that Telegram will return to you, will also give you a link to the bot you createdwhich will basically be t.me/@botname. This will be important for later. Also you can use BotFather options to customize your botputting a profile image, a description or whatever you want. We have explained all this to you in our post about BotFather. Now get the API of an AI Now we have to get an API from an AI. We will use the Free Gemini APIwhich although it has some limits in its use, will be useful for some tests without spending. To get it go to the website aistudio.google.com and sign in with your Google account. When you do, in the bar on the left at the bottom click on Get API Key. Now you have to click on the option Create API key that appears at the top of the screen you have created. This will open a window where you have to create the project for which you are going to use it in order to identify it, for example “Bot Telegram IA”. When you create the project, you can now create the API. When you have created the API, you will see that it appears in the list of API keys. You just have to click on the left, below where it says Clueand a window with the API will open, starting with “AIza–“. Now create the workflow Now let’s create the workflow or workflow using the service Make. Within this program we are going to create a new scenario. We start by clicking on the initial + for the first step, for which you have to write Telegram and choose the option Watch Updates within the options related to Telegram that will appear. When you do this the first time you will have to create a webhook. Basically, it will be like creating a connection, and by doing so you will be able to give it a name and when establishing the connection, you will only have to type the Telegram bot token that BotFather gave us. Once the connection is established, open the Telegram bot that you created in the app, and click on Start. When you do this, the message /start will be written. When you do this, go back to make.com and, at the bottom, press the button Run eleven. This will simply test the connection with the bot. Now, click on the + button on the right of Telegram Bot to generate a new module, and you will have to choose the module to generate an AI response. Simply type the name of the AI ​​you have a token for, in our case Gemini, and choose the option that means generating a response. A window will open to configure your AI. In it, you have to establish a connection using the APIwhich is what we have done above. You will also be able to choose the model you want to use. Keep in mind that the more advanced the model, the more credits the AI ​​will use, and your free API will have limited credits. Now comes the most complex part of all. You have to go to the section messages of this window, and in Item 1, in the field Role you have to put User. Now, in Parts you have to fill out Item 1 by putting in Message Type the option textand in text just below choose option 1. Message: Text. As before we have already executed our project with the Telegram bot, when you click on the value you will get suggestions based on the results of the bot. In these suggestions you will see the 1. Message: Text. You will recognize it in the next window because it is where it says /start, which is what we wrote to the bot. Down in System instructions go to Promptsand in the value of Prompt 1 you also have to put 1. Message: Text. Below, in Response Modalities you have to **choose only the option textdeactivating Imagebecause with the API we will not be able to generate images in our country. Now we are going to create the third step, that of sending the AI ​​response to the Telegram bot. To do this, create a new module, look for the Telegram … Read more

We are not used to seeing traffic cones that place themselves. They are already testing them in China

by

A traffic cone that rolls out of the emergency vehicle alone, is placed in position and forms a safety perimeter before any operator has set foot on the asphalt. It is not a scene that we usually see in our parts, but the truth is that in China they are already testing it and its operation is tremendously interesting. What is happening. Emergency teams in China are testing autonomous traffic cones capable of securing the perimeter of an accident in less than ten seconds. Such as describe Marc Theermann, director of strategy at Boston Dynamics, in a post on LinkedIn, these robots leave directly from the emergency vehicle and move alone to their position, forming a safety barrier without any operator having to cross the road. They can be activated remotely or operate completely autonomously. Click on the image to go to the post The hook: the safety of the operators. Placing cones by hand on a road with active traffic is a truly dangerous task for operators in charge of road maintenance, or those carrying out work on the road. The idea with this technology is simply to eliminate or reduce as much as possible the human presence in the most vulnerable phase of any road intervention. How they work. Researchers from the Center for Research in Technologies, Energy and Industrial Processes of Pontevedra (CINTECX) published a study in 2025 in the magazine Infrastructures that described the design and validation of its “Remotely Piloted Safety Cone”, a robotic system with a similar architecture. The device combines autonomous GPS navigation with RTK correction (a high-precision positioning system), odometry sensors, an inertial measurement unit and ultrasonic obstacle detection. All of this managed by an autopilot and an on-board computer that coordinates movement in real time. The results of the study showed that the most precise configuration managed to stay less than 20 centimeters from the planned route, a more than acceptable margin for this type of operations. Faster than by hand. According to that same studythe estimated placement time per cone with this system is around three seconds, compared to the seven or eight seconds it takes on average for a human operator. In an intervention that requires dozens of cones, the difference is quite significant, especially if this is then combined with systems that can be placed simultaneously and not one after another. And also at night. Best of all, the task can also make it much easier to place cones when there is barely any visibility. And the robotic cones incorporate lighting, something basic for any type of emergency road signage. In Spain we already propose the “less intelligent” version. After the V16 beaconswhich have given a lot to talk about (more for the bad which for the good), the DGT has also explored the use of connected coneswhich would be responsible for notifying in real time of road works or dangers. They would be integrated into the DGT 3.0 platformalong with the V16 beacon, although they are still in the testing phase and very far from implementation. The main difference, as you might expect, is that these cones do not move or position themselves. But it’s already a step. What comes next. The natural step of this technology is not the individual cone, but rather several can be coordinated at the same time, something that we have already seen in tests in China, and that the deployment is reminiscent of that of the drone shows in the sky (less glamorous, but just as addictive to watch). The researchers they point in his study of multi-agent swarms, several robots working together in a coordinated manner, such as the evolution of this technology to apply it in infrastructures.

If you have 400,000 euros you can finally fulfill the dream of owning your own island. The problem is how to get to it.

by

If you like nature, spend hours listening to the birds singing and the rustling of the waves, in Welsh you have a unique opportunity. There, in the Dwyryd estuary, a private island with a charming Victorian mansion is for sale for about what it costs an apartment in the center of Madrid. For around £350,000 you can become the new owner of Ynys Gifftana seven-hectare tidal island with a history connecting it to the Stuart lineage. Of course, the offer has a trick. In a place in Wales… More specifically in the Dwyryd estuary, very close to Portmeirion (Gwynedd), hides a curious island that has just gone up for sale. What is ‘curious’ is not only because of its remote nature, its surroundings or the fact that on its entire surface, of 7.2 hectares, there is a single stone construction. What is really striking is its nature. Ynys Gifftan is a tidal islanda portion of land connected to the rest of North Wales by a spit of land that emerges at low tide and disappears at high tide. Hence, access is not easy and, depending on the time, it must be reached by boat or on foot. Landowner for €400,000. For a few weeks now, the island has added one more peculiarity. The real estate firm Carter Jonas inform that it is for sale for a “guide price” of 350,000 pounds, equivalent to 400,500 euros. The price attracts attention in Spain and even more so in the United Kingdom, where it is not far from what an average home costs. In fact, it is much less than what someone who wants to buy a house in the capital must spend. A few days ago the BBC I remembered that those 350,000 pounds exceed the average house price in the country by just 50,000. If we focus on London, the average price for the last year marks just over 600,000 pounds (£656,694), making getting the Welsh island considerably cheaper. A golden opportunity? More or less. Owning a quiet Welsh island for almost half the price of a house in London sounds good, but Ynys Gifftan has several handicaps that recognize the agency itself. To begin its construction, a country house built with stone is not going through its best moment. “It needs a comprehensive reform,” notes Carter Jonaswhich remembers that the house is divided into two floors and has several living rooms, bedrooms and pantry. Annex has a tool shed. Good landscape, bad services. The truth is that the island takes decades empty and those who embark on the adventure of repopulating it will have to face a series of challenges, beyond renovating the house: there is no electrical connection, the water network channeling dates back to the 80s and the current owners of the land do not guarantee that it is still active. In addition, the drainage system is private. As for the rest of the 17.7-acre (approximately 7.2 hectares) island, it is now partially covered by weeds, almost reaching the house itself. From Jonas they slip that part of the island could be dedicated to grazing. The great challenge. Ynys Gifftan has, however, another more important handicap that any buyer should be aware of. Its inhabitants cannot happily leave and enter the island. Not at least how they want and when they want. During high tide a boat is needed to access the island. When the tide goes out, the way in and out is different: with a short walk along the stretch of land that is exposed. With a walk you reach the continent and from there you can travel to Harlecha town of around 1,600 inhabitants where you will find basic services, such as shops, restaurants or pharmacies. Nature… and history. The future owner of Ynys Gifftan will be able to boast of having an unusual property. To start with its location, in the heart of Eryri National Park (Snowdonia). Second, for his story. Its name, “gift island” in Welsh, is said to be a nod to the island’s past, which was a gift from Queen Anne to Lord Harlech’s ancestors in the 19th century. XVIII.

an “invisible” galaxy made up almost 100% of dark matter

by

The Universe continues to be that great unknown. Not only because of its vast immensity, but because human research and subsequent theories that explain its functioning continue to require tweaks and reformulations. we have seen it when calculating the distances between planets of the Solar System, the size of Jupiter either what is the training mechanism of planetary systems. Now, a research team from the University of Toronto has discovered to the strongest candidate for a “dark galaxy”, something that until now was only considered a possibility. The candidate. The study presents the discovery of CDG-2, an acronym that literally means Candidate Dark Galaxy 2. It is an object 300 million light years away, in the Perseus cluster, with a peculiarity: it is almost completely dominated by dark matter, with a minimal number of stars. Thus, between 99.94% and 99.98% of its total mass would be dark matter and it only delivers a light of “only” six million suns compared to the brightness of tens of billions of the Milky Way. Context. Galaxies are something like the Lego pieces that make up the universe and they all contain dark matter. The dark matter It is something scientifically fascinating: it is invisible, it does not emit or reflect light, but its gravitational influence was the scaffolding on which galaxies were formed and is what holds them together today. In the Milky Way, estimates suggest that between 65 and 90% of the mass is dark matter, depending on the model, but astronomy has always wondered if there were even more extreme galaxies. The “dark galaxies” were until now just a theoretical prediction. Why is it important. To begin with, because it empirically confirms what the theoretical models contemplated, but it has more implications: It opens a new way to detect galaxies from statistically significant groupings of globular clusterswhich serve as a trace. As a case study: the most probable hypothesis is that neighboring galaxies ripped away the gas necessary for star formation, leaving only the skeleton. It makes us look at its “twin” CDG-1 with different eyes. Detected previously, it could be a case of an even more extreme dark galaxy, possibly a pure dark matter halo. How they discovered it. The research team came across this galaxy in a striking way: looking for its shadow, since it is practically undetectable. Their fingerprints were four globular clusters, small dense concentrations of stars around the Perseus cluster. After analyzing its disposition with statistics and ruling out that its grouping was a matter of chance, they pointed the three most powerful telescopes available, Hubble, Euclid and Subaru, towards that region and created the image that evidenced its existence. Is, in the words of the main researcher Dayi Li, “the first galaxy detected solely through its population of globular clusters.” Image: NASA, ESA, Dayi Li (UToronto); Image Processing: Joseph DePasquale (STScI) Pending subjects. However, CDG-2 is still a candidate and not a confirmation, which is why it keeps its name. To confirm with certainty the mass of dark matter it would be necessary to measure the velocities of its stars or clusters, something technically very difficult with current technology due to how little they shine. It will be necessary to wait for James Webb and new Euclid observations to improve the image of this object to better define it or continue finding more dark galaxies like it hidden in the universe. It would require measuring the velocities of its stars or globular clusters, something technically very difficult given their extreme tenuity. The next few years, with James Webb and new observations of Euclid, will be crucial to refine the portrait of this object and track whether there are more galaxies like it hidden in the large clusters of the universe.

A plant was on the verge of extinction in the Mojave Desert. So they built a solar park on top

by

The Mojave Desert is not only a paradise when it comes to filming movies, setting video games and name operating systems: It is also home to thousands of plant species that are accustomed to an extremely hostile climate. It is estimated that there are about 2,000 species and a very specific one is in danger of extinction. Until they decided to build one of the largest photovoltaic plants in the United States on top of it. The Gemini Solar Project. In short. The journal Frontiers in Ecology and Evolution revealed a few weeks ago the results of a curious study. The ‘threecorner milkvetch’ plant (which has a name for everything except a plant) went from 12 specimens in the Mojave Desert to 93. This plant was being evaluated for inclusion in the Endangered Species Act in the United States and not only has its number multiplied: the new plants are larger and produce more flowers. And they have “only” had to build one of the largest photovoltaic plants in America on top of it, next to Guanchoi in Chileto achieve it. Threecorner milkvetch. It is a creeping plant that has curious needs: it only grows in sandy soils of the Mojave Desert. However, it is dependent on rainfall because its seed remains dormant in the soil and only germinates and reproduces with favorable rainfall. In dry years, it remains completely unnoticed, waiting for a little rain. And it is so rare that the species remains under evaluation for status as threatened or endangered under U.S. Fish and Wildlife Service regulations. In the same desert there is another threatened species: the desert tortoise Gopherus agassizii. The habitat of the two species should be the last one on which it would be decided to build a photovoltaic plant, but there is the Gemini Solar Project. The plant Megaplant. When such an installation is to be carried out in the desert, a technique known as clearing and leveling is used. In essence, all vegetation is removed, the land is leveled and prepared for install the pillars of the solar panels. Not only is a lunar landscape created, but any type of latent seed beneath the surface, such as that of the threecorner milkvetch, is destroyed. However, the Gemini Solar Project’s approach was different. The company wanted the land because it is especially ‘fertile’ within the US to harvest sunlight, but concessions had to be made. One was to minimize the alteration of the habitat of both species to conserve the desert surface with all its biological resources, preserve the topsoil and adapt the facility to the natural relief. On the US Geological Survey website we can see photos of little turtles between the panels. Works. This is part of what we know as ‘ecovoltaics’, with a branch called ‘agrovoltaics’ that we have also talked about and that, although it can be used by companies as a facelift, it serves to unite energy activities with agricultural activities. In the study on the impact of the Gemini Solar Project and the evolution of the plant, researcher Tiffany Pereira discovered what we have mentioned: there were more plants and they were healthier. This showed that the energy company had done its part by not destroying the soil because the seeds had been able to germinate, but they found something else. The plants inside the installation evolved earlier than those outside it and grew not under the panels, but in the strips between the rows. This implies that they still need intense sunlight to mature. The yellow zone is where the Sun shines the most hours. The blue one is the stripe that varies depending on the position of the Sun. The red one is where direct light never shines. Okay, but then… what is the role of the panels in the improved evolution of these plants? The hypothesis used by the researchers is that the panels provide partial shade on the groundslowing down evaporation. We have already said that seeds are dormant until they have the necessary humidity conditions to germinate, and in this context, a more humid microclimate has allowed plants to grow more and produce more seeds. Not all the field is oregano. Now, like almost every scientific study, we look at the other side of the coin. The rainfall in recent years has been favorable and we will have to see what happens with periods of prolonged drought. In a few years we could talk about long-term effects. But, in addition, this absence of plants under the panels could indicate a possible loss of potential habitat in very humid years. In any case, Pereira’s study is not isolated. Other studies point to improvements in both the number of flowering plant species and pollinators in agrovoltaic installations in a state like Minnesota. AND in China there are also indicators that those photovoltaic plants in deserts is contributing to the moisture pocket construction in which plants can thrive more easily. As we said, it remains to be seen the impact of the panels on the creation of a “new” biodiversity in the long term, but for now, what is evident is that it is not necessary to raze land to build a photovoltaic plant.

Apple has been setting up a health system parallel to public health for years. The question is whether public health will do something about it.

by

I haven’t worn a watch of any kind on my wrist for years. Partly for convenience, partly for not having another device to distract myself with. The paradox is that I find it more and more advisable to wear or give a smartwatch, precisely because of the leap they have made in monitoring our health in recent years. The other day, Dr. Miguel Ángel Cobos Gil, a prestigious Spanish cardiologist, told us at a press event that “the Apple Watch provides more parameters than anyone admitted to a coronary unit.” It made me think: we already have very reliable medical technology in our pockets, on our wrists and even in our ears. And now what? A parallel system to saturated healthcare Healthcare in Spain has just concluded a few days of strike in which they demand improvements in a system with problems: saturated primary care, insufficient personnel, underfinancing or territorial fragmentation are just a few. Spain is not the only one like this. Countries like the United Kingdom, Canada, Italy or Portugal are struggling with similar situations, and if we look at Latin America or Asia the photo even it gets more complicated. Doctor Miguel Ángel Cobos Gil at an Apple Health event in Madrid. It is no coincidence that Apple has spent years setting up a whole parallel health system through its best-selling devices. You can now take a medically approved EKG with Apple Watch In a few minutes, the iPhone notifies you if you have risk of falling when analyzing how you walkand AirPods are increasingly looking more like a smart sonotone. Apple is the one that is taking the most solid and visible steps, but it is not the only one. Samsung integrates teleconsultations, a game to detect Alzheimer’sbooking diagnostic tests and ordering medications at Samsung Health —starting with Indiawhich is no coincidence—; Huawei gives you ten health parameters in a single gesture with its Watch 5; Google bets on a medical coach with AI on top of Fitbit and Pixel Watch data. Almost the entire tech sector is looking at the same place. Useful technology to help us with our health is already here. The problem is how to make all that data that our devices give us use for something in a collapsed public system. Your doctor doesn’t have time to look at the data on your watch And now we have been in this house for ten years: We have a lot of information about preventing diseases and devices that can help us do so. However, there is still no effective system to address it. Cobos Gil summed it up bluntly: “urgent care works.” When something really goes wrong, the system responds. The problem is before, in that period of time where an asymptomatic disease could be detected and treated with a change in habits or a simple medication, but where the family doctor cannot dedicate fifteen minutes to you if he does not see something serious or actionable. Hypertension doesn’t hurt. Atrial fibrillation does not warn. Apple Watch possible hypertension alert system And this is exactly where technology comes in—or should come in—. A smartwatch does not sleep, has no waiting list and does not need you to go see it: it passively monitors whenever you wear it, accumulates months of data and notifies you when it detects an anomaly. Cobos Gil mentioned something that illustrates the difference well: a conventional cardiac holter monitor must be taken for about 24 or 48 hours, and many times it does not capture anything because the arrhythmia does not appear in that time window. With three months of data from the Apple Watch, he says he’s gotten diagnostic information he otherwise wouldn’t have had, and has even “had to anticoagulate patients who were cleared by a Holter monitor.” This gap is especially relevant for the older population, especially if they live alone. Spain is aging fast and a silent heart attack, a fall, or an arrhythmia that is accelerating are situations in which the time between the event and medical attention is everything, and in which not having a family member or caregiver nearby—the child in another city, the grandchildren in another country—creates a very vulnerable situation for these people. These are situations that happen. In Applesfera we have just told the case of a lady who suffered a fall due to an epileptic attack in Torremolinos and his Apple Watch helped everything end in a scare. The striking thing about this is that hospitals already do this type of monitoring in extreme cases. When a modern pacemaker or defibrillator is implanted, the hospital monitors the patient remotely and can intervene if something goes wrong. A watch like the Watch takes that logic from the hospital to home: it allows a son in Madrid to see in real time if his mother’s heart in a town in Teruel is beating strangely, or to receive an alert if she has fallen and hasn’t gotten up. It is not medicine of the future. It is medicine of the present waiting for the system to learn to incorporate it. The limit that no one has set Tim Cook at WWDC 24 What Apple, Samsung, Huawei or Google have built so far is the beginning. Apple has been working for years on non-invasive blood glucose monitoring —without being punctured, through optical spectroscopy—and the most solid rumors suggest that could come to the Apple Watch in 2027 or 2028. Before that, I’m pretty sure we’ll see an AI-powered medical assistant built into the Health app — known internally as Mulberry Project— trained with your real clinical data. Tim Cook has been repeating for years that the Apple’s greatest contribution to humanity will be in healthcare. What it doesn’t say is exactly how far. Because the question that these devices do not answer is one that seems very important to me: Where do they set the limit for themselves, and who sets it for them from the outside? Early detection of … Read more

Anthropic releases a new feature to download all your memory to leave ChatGPT and switch to Claude

by

This weekend Anthropic has gone from being an AI used by the Pentagon, other US agencies and having partners such as Microsoft or Amazon to total ostracism: from Friday at 5:01 p.m. It is classified as a “risk to the supply chain”. Total veto, a serious threat to the survival of a company valued at 380,000 million dollars and also a challenge for those entities that in less than six months will have to transition to another alternative. The Pentagon itself He already has an agreement with OpenAI to succeed him. Anthropic’s situation is delicate to say the least serving its strategic clients and alliances, something essential to continue growing in the tough battle of intelligence. The company led by Dario Amodei, which was firm in its principles when expressing its concern about the use of artificial intelligence for mass civil surveillance and the development of weapons capable of firing without human intervention, has already announced that he will contestbut for now they look rough. He only has the civil…in every sense, because Claude has risen to number 1 for free downloads in the App Store in the United States, as reported by CNBC. Because yes, this tug of war with the US government has brought an increase in the popularity of Claude, less known than other alternatives such as ChatGPT or Gemini. On the other hand, this movement in which the US Administration has said goodbye to Anthropic in favor of OpenAI also has a reading in which Claude wins: the terms of the agreement and how it affects ChatGPT users. Anthropic Coup de Effect. So Anthropic has been taken out of the sleeve a new feature to facilitate the transition from other AI models, such as ChatGPT or Gemini, to Claude. Because if you have been using ChatGPT for a while for example and already knows youstarting from scratch is a step backwards in every sense. The new feature allows you to import all your memory from other models into Claude so that it immediately knows everything about you (everything that your previous AI already knew). You no longer start from scratch. How to download your memory and load it in Claude. To incorporate your preferences and context from other AI providers into Claude you have to do two steps: Copy and paste the prompt below into the AI ​​you normally use, like Gemini or ChatGPT: I’m moving to another service and need to export my data. List every memory you have stored about me, as well as any context you’ve learned about me from past conversations. Output everything in a single code block so I can easily copy it. Format each entry as: (date saved, if available) – memory content. Make sure to cover all of the following — preserve my words verbatim where possible: Instructions I’ve given you about how to respond (tone, format, style, ‘always do X’, ‘never do Y’). Personal details: name, location, job, family, interests. Projects, goals, and recurring topics. Tools, languages, and frameworks I use. Preferences and corrections I’ve made to your behavior. Any other stored context not covered above. Do not summarize, group, or omit any entries. The model will return everything it knows about you in a block of text, which you have to copy and paste later into Claude. Go to ‘Settings‘ > ‘Capabilities‘and there in Import Memorypaste the answer. Then, tap ‘Add to memory’. From that moment on, Claude already knows what your previous AI knew. It has small print. This is a feature for users on a paid plan (Pro, Max, Team or Enterprise). If you are on the free version, at most you will only be able to have that context in that conversation, but not permanently. In short: the import is free as a manual process, but for Claude to remember it permanently a payment plan is required.

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

by

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

I have tried all the browsers with AI on the market and the one that works best is the one that started the worst: Dia

by

I started using Arc in the summer of 2024. I was slow to get into it (I had tried it before and found it too capricious, too determined to teach me how to sail when I already knew) but when I arrived, I really arrived. Vertical tabs. The spaces. The way he organized the digital day without me having to think about it too much. Arc to me was not just a browser: it was a work environment. And then The Browser Company Dia announced. I remember it with some annoyance. Josh Miller, the company’s CEO, uploaded a video talking about “something new,” and Arc was in “minimal maintenance,” a euphemism for not saying the word “abandonment.” The Arc community complained, rightly so, and I joined the discontent. They had built something great and threw it overboard at the first opportunity to pursue the AI ​​chimera. Still, I tried Dia as soon as I could and wrote about it: You opened Dia and saw Chrome. Chrome with better typography, Chrome with more careful animations, but Chrome nonetheless. No split tabs, no gaps, no anything that had made Arc great. Just a chatbot in the sidebar. I closed it and went back to Arc, which continued to work despite the abandonment warnings, until I started trying other AI-based browsers. Months passed and Dia was updated, week by week, with a striking cadence. And at some point I started to notice something: the things I missed were coming backsometimes even improved. First the vertical tabs, which Arc had popularized and which Chrome has just announced that it will also adopt, something that says a lot about who sets the pace in browser design. Then the groups of eyelashes, with that aesthetic care that has always been a trademark of the house and now goes further than before. Other browsers already have this feature, but “not like this.” Recently, the split viewwhich I have been using for years in Arc and which is one of those functions that, once you have it, you don’t understand how you navigated without it: Simultaneous view of several tabs in a single window. Split tab view to display multiple tabs in a single window. Image: Xataka. Tab groups have even partly replaced my use of favorites. You can create them by hand or see how they are automatically grouped and renamed when you open multiple tabs from the same place. Its design and user experience are fantastic. Image: Xataka. The set favorites are still there. Tabs in the sidebar also ended up coming to Dia. And between both blocks, the groups of tabs. Image: Xataka. There is a pattern in The Browser Company that you should have already learned with Arc: they release something that seems incomplete, almost “psché”, and then they improve it until you can’t put it down anymore. It took me two tries to fall in love with Arc. Something similar has happened with Dia, only the process has been longer and the reconciliation more gradual. And that boss now has to live with a new owner, because since September This company was bought by Atlassianwhich wants to make Dia the reference for working with AI. Nothing has changed at the moment on a day-to-day basis (pun intended) of the browser. What Dia has done smartly (and differently than Arc) is start almost from scratch and give up all the weirdness. Arc asked you to adapt to it, to learn its logic, to assume its curve. And Dia does exactly the opposite: she is very Chromiumvery familiar, very little foreign to anyone coming from Chrome and not as rigid as Arc. That takes a toll: some of Arc’s more radical ideas have been lost in the transition, but it also means it doesn’t create as much friction for the average user. You open Dia and browse. There is no twenty-minute tutorial on how to think about tabs, which is something that penalized the growth of Arc: those of us who used it loved it, but many people left when they saw that they did not understand the proposal. The weight is what catches my attention the most on the negative side: it’s around gigabyte, which is an outrage for a browser. And there is no mobile version yet. That hurts more, because it means the experience is split between devices, and the consistency Arc was trying to offer across platforms doesn’t yet exist on Dia. I hope they don’t take long. In theory it will arrive this year. Regarding AI, it is not what I use the most. Of course I use Claude or Gemini, I mean Dia’s chatbot sidebar. It’s not something I used on Dia nor have I used much on Neon, Atlas or Comet, the other three that I’ve tested in some depth. The chat in the sidebar is a good complement, I can ask it something about the tab I have open, ask it to summarize several at once, respond with context of what I am reading; but it is not the focus of my browsing experience. All three browsers conveyed at their launch that AI would change everything, and reality is more modest– It’s useful, sometimes very useful, but it doesn’t transform your workflow in the same way that a good tab design does. At least in my experience. I have tested more browsers that leverage AI for their value proposition. And they all have their strong points: Comet It is very fast and efficient searching for information in real time. Atlas is very capable when you need to systematically extract data from multiple pages, but none have the level of care in the experience that Dia has. Opera Neon is a browser built from the ground up for the AI ​​era, with much more than a well-placed chatbot. But it’s not just that they work. Dia feels good. There is something in the design, in the animations, in how the groups of tabs are constructed, that remains … Read more
