Google has been trying to create your WhatsApp. With RCS it is achieving it without it seems

by

Google has been trying to create its own messaging platform to stand up to WhatsApp. Without success. He tried with Hangouts, with Alloeven with Google+. All these projects ended as Stadia, Chrome apps o Android Things: closed and forgotten. Meanwhile… Apple has consolidated Issssage as its native channel in some markets, especially in the United States. And goal has made WhatsApp the default tool to talk to anyone in the middle of the planet. Google, despite controlling More than 70% From the mobile market with Android, it did not have a direct route with its users. And that is starting to change thanks to RCS. RCS is a technical standard, not an application, designed in theory to replace the SMS and offer a more modern messaging on smartphones. Let send images and videos, have reading confirmations, creating group chats … but its reach goes beyond the interface: It is the first relevant messaging channel in the Android ecosystem that does not depend on an external app like WhatsApp or Telegram. The key is how Google has managed to position it. It has not launched a new application. Has integrated RCS directly on Google Messagesthe native messages on Android. In the United States, the deployment is almost total: more than one billion RCS messages are sent every day, according to figures announced by Google. “Only” are three messages per inhabitant and day, but something is. Google controls its infrastructure, its APIs and its evolution. And he has done it without asking the user to download anything, nor that he believes a new account. It is there. Works. And more and more people use it, often without knowing it, because they believe they continue using the SMS. But not anymore: it is a RCS controlled by Google. That final nuance is key. Because although RCS is presented as an open standard, what is growing is not a decentralized network, but an RCS with an accent of Mountain View. Google has not only promoted its deployment: it has assumed its technical control in many countries, jumping to the operators. Since in 2019 he decided to offer it directly – without waiting for telecos—RCS has gone from forgotten promise to functional channel. And now, Apple. Another silent victory: Apple has been forced to incorporate it for European regulatory pressure. That does not make Imessage interoperable, but it has eliminated the largest brake that was to the global deployment of the new standard. From there, the old SMS – with its limits and compression – has ceased to be the default language between Android and iOS. It is RCS. A more modern channel, encrypted … and with owner. And that is the real change. Google has not created its WhatsApp. He has done something more subtle: He has reconverted Android’s native messaging on his own platform. Without calling it that way. Without asking you permission. Without seeming it. In Xataka | Gemini should not be called Gemini. It should be called Google Outstanding image | Google, Xataka

There are thousands of more efficient systems to create a “white smoking”. The Vatican refuses for a reason: the Holy Spirit

by

On October 26, 1958, one of the More Rocambolescas stories Around al smoke that announces The choice of a new Pope. That morning, smoke appeared clearly white leaving the chimney of the Sistine Chapel, and the crowd gathered in the Plaza de San Pedro exploded in jubilation. However, shortly after the smoke became dark, and the faces became disbelief. That confusion stressed the need to improve the clarity of the signal and not leave everything in Holy Spirit hands. A choice between the human and the divine. When the cardinals today enter the Sistine Chapel for Start the conclave, will invoke the Holy Spirit With the song Veni Creator Spiritusan ancestral prayer that summarizes the tension between human reason and spiritual discernment. In Catholic theology, the Holy Spirit It is one of the three people of the Trinity and is considered the true guide of this process. Although the election of the Pope involves politics, strategy and human relations, it also presents itself as a Cooperation with the Divine. Some describe it as a silent presence that guides, does not impose, as a “good educator”, As Benedict XVI saidthat inspires, but does not make decisions for men. Some of it remains in the essence of the final announcement through the white smoke. One thing seems clear: the Church rejects any technification of the moment. The conclave that confused everyone. The unusual scene that we commented at the beginning should choose the successor of Pope Pius XII. That day, during one of the votes, it appeared clearly white smokeHabemus Papam, or so they thought. The people gathered in San Pedro shouted for joy, the bells of the Basilica began to repair and some media came to announce the choice. However, minutes passed, then hours, without the official announcement or the new Pontiff appeared. Finally, the Vatican clarified that he had tried to An error: The white smoke had been the product of incomplete combustion or a poorly calculated mixture, and in reality the consensus necessary to choose potatoes had not yet been reached. The confusion made it clear that some things had to be improved, something that the Vatican corrected in part over time and, since 2005, with the accompaniment of the bell repique to confirm the choice. The language of smoke. It is part of the ritual: every time the Catholic Church chooses a new Pope, millions of people look towards the small chimney from the Sistine Chapel Waiting for the signal: Black smoke if there is no agreement, white smoke if the successor has been chosen. What seems like a simple symbolic gesture is, in reality, a Extremely precise operation and loaded with engineering, chemistry, symbolism and tradition. Burning ballots and the use of smoke as a form of communication They date back to the fifteenth centurywhen a way to transmit the result of the choice without breaking the secret of the conclave. The image of smoke ascending to heaven evokes ancient religious and biblical rites, where smoke was understood as a spiritual bridge between the human and the divine. Preparations and technology. After the Death of Pope Francis At 88, the Vatican confirmed that The conclave It would begin today May 7 with a special mass in San Pedro, followed by secret votes in the Sistine Chapel. There have been installed Two stoves: One to burn ballots and another to generate the visible smoke. These stoves are connected through A metallic ductcarefully assembled and inserted by technicians who work without damaging the Renaissance structure of the chapel. Each tube union is sealed, previous smoke tests are carried out and firefighters are available in alert in case any technical failure occurs. Everything must work without error margin: an escape or an ambiguous signal would turn the liturgical act into a global crisis broadcast live. The 1958 example does not forget. The chemistry of the message. To ensure that the world clearly sees what happens within the conclave, smoke is not exclusive product of ballot combustion. The BBC counted that chemical compounds packaged and electronically activated are used. To generate black smoke, potassium, anthracene and sulfur perchlorate is mixed, and for white, potassium, lactose and pine resin is used. In the past He tried with wet and dry strawbut the results were inconsistent. Since 2005, the Vatican also sounds like those bells of San Pedro to visually and loudly confirm that a new pontiff has been chosen, avoiding confusion such as those that have occurred in the past. Negative to modernize. The truth is that the system could be much easier if the Church would like to take advantage of some of the new technologies. However, despite the advances and suggestions of implementing colored lights, digital alerts or more modern electronic systems, the Vatican insists on Keep the ritual as it is. If you want and from your perspective, for your excellence it is not just about communicating a news, but about preserving a liturgical experience with deep theological burden. As The historian Candida Moss explainedthe smoke not only informs: it incorporates the faithful to the mystery, makes them feel participants of a transcendental moment in the life of the Church. The papal choice is not (alone) an administrative event, but a ceremony full of centuries of faith, solemnity and spiritual continuity.

Create your own camera sensors

by

Huawei has been obsessed for years to achieve full technological independence. He succeeded with his chips, is close to achieving it with his software, and already Face to giants like Nvidia To stop depending not only on the United States, but also on Taiwan. The last information that comes from China speaks of a new plan drawn by Huawei. One in which camera sensors, historically provided by giants such as Sony or Samsung, will also be their own land. Own sensor. We read in Weibo Thanks to Digital Chat Station, one of China’s most reliable filters, the new Huawei plan to lead the photographic career. The company is working on two sensors, one of one inch and another with 1/3 ”size, with resolutions of 50 megapixels. Both sensors have technology Ryybsomething that makes them different from all the proposals that are currently in the market. Ains, the Huawei P30 Pro. But Huawei already had Ryyb. Yes, but not of your own manufacture. Huawei has modified sensors provided by other manufacturers to change its RGGB structure. What does all this mean? RGB is a color model that represents the colors by combining three basic components: red (red), green (Green) and blue (blue). It is important to understand how they work. The filter Red (r) Let the red light and blue blocks pass. The filter Green (g) Let the green light pass. The filter Blue (b) Let blue light pass. This system is based on the way in which the human eye perceives colors, since our visual receptors (cones) are sensitive to these three wavelengths. A normal sensor (RGGB) simply has more green pixels, because the human eye in most sensitive to green. Why Ryyb. If the industry has been moving in the RGGB for years, why bet on the RYYB (Red, Yellow, Yellow, Blue)? Replacing green pixels with yellow means that, according to Huawei, sensors can capture much more light. The yellow is a mixture of red and green, so basically fulfills the function of green, with a pixel that lets in more luminosity. The filter Red (r) Let the red light and blue blocks pass. The filter Yellow (y) Let Green and Red Pass The filter Blue (b) Let blue light pass. The main problem is that these types of sensors require more processed, since green is not pure and has to be rebuilt by software. It is not something that has worried Huawei too much in recent years, since the results are spectacular. Ready for Mate 80. The leaks do not speak in the long term. These sensors would be ready for the arrival of the Huawei Mate 80, Telephone whose launch is scheduled this year. This telephone, above the pure family, would be an entire technological muscle exhibition, in which processor, camera sensors and manufacturing would be 100% national. One more milestone to the collection. With the Huawei Mate 70 chip, the Chinese giant achieved a new milestone: his first 100% national manufacturing chip. If you manage to manufacture your own camera sensors, you will get another trophy to add an extensive list. GPUS for Iaone of the best electric car chargers, The first triple folding in the world either Complete independence in software. Huawei is building its own parallel realityin a context of Revenue record and with a flattering future in sight despite the numerous obstacles it faces.

What is Google Firebase Studio and how this tool works to create artificial intelligence applications

by

Let’s explain what Google Firebase Studio is, the new tool for Create applications with artificial intelligence. You can do it without writing a line of code, just describing Google’s AI what you want, so that it generates the code for you. At the end of the process, you will have a functional web application that you can use and publish to see the light. Obviously, this is only prototyped, because you will also have the option to edit and review the code on your own to make sure everything is fine. What is Google Firebase Studio Google Firebase is the Webs and Applications Development Platform Created by Google. The idea is to cover most of the needs of developers, being able to store software, provide notification system for apps, necessary databases and authentication services or use analysis. And in 2025 Google has created Firebase Studio, which is a section within this platform that allows you Create webs and apps with artificial intelligence. You do not have to do anything, it’s something like Vibe Codingwhere AI generates the code and you just have to check it. The idea of ​​this service is that you simply have to Describe the type of application you want to create. For that, you must define what you want me to do in detail with a natural language. You have to describe what you want to do with the app, how it should be, its functions and anything else you can think of the same as if you will explain to a person. For this, Google Firebase Studio uses Geminithe artificial intelligence system of the company itself. Specifically use Gemini 2.0 Flashwhich will be the one that is responsible for interpreting your description, and to generate the application code in a few minutes. Of course, remember that what this tool will generate They are applications prototypes. Once you have it, you may have errors, and you will have to check the code, make the corrections you want and click on Post so that Google is in charge of hosting her. How to use Firebase Studio The first thing you have to do is enter the Firebase website, whose address is Firebase.google.com. Once inside, click on the button Begincontinue with the introductory steps that appear when you are going to use this program for the first time. This will take you to the Firebase Studio page, whose address to enter later is Studio.firebase.google.com. The tool interface is similar to that of an artificial intelligence chatbot, you have a writing field where you should Define what you want the application to do. Then click on Prototype with AI. This will take you to a Gemini page, where you are shown Suggested options and design For this application, as well as a name. On the right you have the icon of a pencil in case you want to make changes in the suggestion. When you have the app as you want, click on Prototype This App To create it. If you click on the edit button with the pencil iconyou will go to a page where you can manually change what you want within the description, including colors or functions. You also have a field to write the changes you want to make and that the AI ​​is in charge. When you finish click on Save. You will also have a button Prototype This App To start creating it from this window. And that’s it, then you’ll see in front of your eyes how the application code is createdand how after doing so, possible errors are sought and corrected. And that’s it. When you finish you will have a demonstration of the application to try it, and below you will have the button Edit of Code to review and make changes in the code. Up to the right you have a publishing button so that the web application is accessible. In Xataka Basics | Gemini Advance functions that become free in March 2025

What is this new iPhone and Mac app and how to use it to create images with artificial intelligence

by

Let’s tell you What is and how to use imagine playgroundthe new application based on Apple Intelligence To create images. This tool has begun to arrive and settle alone in the latest iPhone and Mac models after the latest updates of its operating system. It is a tool with which Create images by artificial intelligencebut that works quite different from that of alternatives such as Chatgpt, COPILOT either Gemini. We will start the article explaining your concept and operation, and then we will tell you how to use it. In this article we will use macOS catches, because the screen is larger and looks better. But the operation is exactly the same on the iPhone, only with the interface adapted to the vertical format. What is Playground Imagine Imagine playground is an application for Create images through artificial intelligence. It is an application that will be automatically installed on your MAC and your iPhone when they receive their latest updates, which implement the deployment of Apple Intelligence In Spain. The images are going to be created from scratch, but their way of working is different. You won’t have to use full promptsyou don’t have to tell you a complete description of what you want. Instead, what you will do is add concepts and elementsand with the sum of all of them the image will be generated. For example, you can add a photo of yours, from other people or anything else in your gallery. Then, imagine playground allows you Add objects, funds, environments and accessoriesand you can also write small PROMPTS that add to the elements that are added. The idea is to create the image from the sum of several conceptsand not of a single description. The advantage of this mechanics is that it is easier to add small modifications to the image, since you only have to eliminate concepts of the sum or add others. The quality of the images created is much lower than that you will find with online services such as the competition, but It works locally on your devices. This means that the images are created in your Mac or your iPhone directly, and not on Apple servers, which prioritizes privacy. Image Playground is available for iPhone from 15 Pro and 16 that have iOS 18.4 and higher versions. Also for iPads with M1 chip onwards or A17 with ipados 18.4 or higher, as well as mac with M1 or superiors with macOS 15.4 or higher. How to use PlayGround Image The way to use playground is simple. You open it and have a bubble in the central part, and below you have The elements you can add. You have Apple suggestions, such as funds, people, environments or accessories, but below you also have a writing field, a people selector or the possibility of adding other photos to use them. If you want to select people, you will go to the ones you have labeled in Apple photos. In each of the people You can choose different faces or photosand you will see the results that are generated with each of them. Now what you have to do is Go adding all the concepts you want. Remember that you will also have a field where you can write the concept or description to add it. When you have it, click on the central bubble to see the slide pass. When you press in the bubble you will go to the preview, where you will be able to see the creations. As you slide, Playground will create new images, so you can infinitely slide through the alternatives to see one that you like. You can also choose between three styles different image. The style of Animation It will make 3D images, and the other two are two 3D styles to make drawings in different ways. Now you just have to explore and experience, being able to Add or remove concepts to your liking. When you have something you like click on the button Okand you will see the image big. Now you will have options to share the image or delete it.

Chile asked Chatgpt about their culture. The answer was so loose that Latin America has joined to create LATAM-GPT

by

Observe the development of Generative It is most curious. In the United States they are large technological, and startups such as OpenAIthose who have marked the rhythm. In China, companies are also developing their modelsbut the government has a particular interest in Push this technology For technological purposes, of course, but also social and doctors. And now Latin America has joined to create its own Chatgpt. It will be called LATAM-GPT And the motivation to create this model is curious: a Chilean center did not convince a chatgpt response on Latin American culture. The question. “Describe Latin American culture in 500 characters.” That was, how we read in BBCthe request of some researchers from the National Artificial Intelligence Center -Cenia- from Chile to Chatgpt. His answer It was the following: “Latin American culture is a vibrant amalgam of indigenous roots, African influences and European heritage. It is characterized by its rich diversity in music, dance and gastronomy, reflected in festivals such as carnival and the Flower Fair. Its art, from muralism to literature, shows a deep connection with the history and local identity. The warmth, the sense of community and the celebration of community. pillars that enrich this dynamic and diverse culture. ” I have to say that I just asked for it and the answer is different, but pivot over the same points, such as the fusion of indigenous, African and European inheritances, the taste for music and dance, colorful gastronomy and traditions such as carnival to give rise to a colorful cultural mosaic. LATAM-GPT. This response did not satisfy CENIA researchers, who considered that, although it is a Llm Of great quality, “his understanding of the Latin American context could be enriched and perfected.” Come on, they are convinced that the answer, although correct in broad strokes, needs to qualify a lot to better reflect the peculiarities of the culture of each Latin American country because Chatgpt gave an answer too … Generalist. And that response for the region user will be LATAM-GPT. The intention is to be a Language model of and for Latin America and the Caribbean. The desire is that it addresses the common problems that language models have when interpreting idioms, cultural references and typical expressions of the Latin American context. Álvaro Soto, director of Cenia, states that US models hallucinate because Latin American data with which they have been trained are very scarce. “We do not seek to compete with Openai or one of the giants. We want an own model of Latin America and the Caribbean, with the cultural requirements and challenges that implies” – Cenia Goals. It is triple. On the one hand, what we have just mentioned: that it has a greater context when addressing issues related to the culture of each of the Latin American countries. On the other, that is open and public, allowing each developer to adapt applications to local needs in areas such as education, politics, economy or the environment. Finally, perhaps the most important for something that countries in the region are looking for: stop depending on foreign models and technologies. Mexico, for example, has put on the table the intention of carrying out different projects within a great umbrella called Plan Mexico which seeks to enhance the sovereignty of the nation in several matters, being the technological one -with its own semiconductor industry or of electric vehicles– One of its legs. Financing. With Latam-GPT, it also seeks to promote technological innovation of the region thanks to a tool that can help others seek to develop their potential. But of course, carrying out something like that requires money, and it is something that is not going to be left only in the Cenia. Chile has postulated as the leader of the project, but countries such as Mexico, Argentina, Colombia, Peru, Uruguay, Costa Rica or Ecuador have not taken long to join. There are also Spanish and American institutions on this ship. It has financial support from associations and academic institutions of these countries, but there is also government support to develop this artificial intelligence. Several countries are immersed in Latam-GPT Resources. For training, researchers will use the infrastructure of the University of Tarapacá, in Chile. It will use a super -tank to train the model with more than 8 TB of data collected from public and private libraries. That training will take about 40 days and it is expected that, for summer of this 2025, LATAM-GPT can be accessed. Investment in infrastructure will be about 10 million dollars. Now, one of the problems can be the consumption of the training center. We have already seen in Spain that Not everyone looks good the installation of Data centers To train AI due to high consumption of both water and energy, but from CENIA they expose that consumption in the first of the two stages will be 135 kWh. The University of Tarapacá is in Aricato northern Chile, where there are A great energy matrix composed of renewables and the idea is to ‘throw’ of them to supply electricity. In addition, from the agency they comment that “the cooling system – of the servers – will not generate water consumption due to the availability of cheap and abundant energy in Arica. CO₂ emissions associated with training will be 0.96 tons.” Necessary? This would be, if the accounts are correct, that the training of this LLM will be more ecological than that of Google or OpenAi models, but there are some challenges ahead. One has to do with the protection of data they use to train the model. The researchers affirm that the main policy for the shelter of intellectual property will be transparency, with open sources that comply with the copyright laws And, at the same time, make automatisms of Anonymization of personal data. On the other hand, there are those who ask that all this … for what. Ulysses Mejías, of Mexican origin, is a professor at the State University of New York and has … Read more

Salt water, CO2 and electricity are the new recipe to create more sustainable cement and concrete

by

Cement is one of the most used artificial materials on the planet, but has two problems. The first, environmentalsince its production emits a remarkable amount of greenhouse gases. The second, the shortage of raw materials such as sand, whose mined also has an environmental impact. A new material. A team of researchers from the Northwestern University and the company ️Cemex Innovation Holding has developed A new construction material through a process that combines marine water, carbon dioxide (CO2) and electricity. This new material can be used in the production of cement and concrete and, according to its developers, in its production more CO2 than it emits. That is why the new material has the ability to make the most sustainable cement and concrete production. Salt water, CO2 and current. The method to create the new material begins by introducing electrodes in the salt water to circulate an electric current that separates water molecules into hydrogen gas and hydroxide ions. As explained by the development responsibleWhile the current circulates, CO2 bubbles are added to the water in order to change the chemical composition of the water by increasing the concentration of bicarbonate ions. The ions of these two compounds (hydroxide and bicarbonate) react with other ions that can be dissolved in marine water, such as calcium and magnesium. From these chemical reactions both calcium carbonate (CACO3) and magnesium hydroxide arise. The first compound, Continue explaining the teamit is in itself a carbon sink; The second, on the other hand, is able to capture additional carbon interacting with CO2 molecules. Copying nature. According to its developers, the process is similar to that used by corals and mollusks to build their structures and shells. The key difference is that these animals use their own metabolism instead of electrical energy to detonate the chemical process. Different uses. The resulting material, a Mixture of calcium carbonate and magnesium hydroxidecan be used as a substitute for the sand or gravel used in concrete manufacturing, but can also be used to produce cement, plaster and even paint. More control. The resulting material has an important advantage and that its properties can be altered by introducing small changes in the elaboration process such as the current and its voltage, or the duration of the injection of CO2, among others. Thus it is possible to achieve a more porous or more dense and hard substance. The details of the process and its results were published In an article In the magazine Advanced Sustainable Systems. Optimizing the capture of CO2. Another important factor is the calcium carbonate ratio and magnesium hydroxide obtained in the resulting material. This ratio depends, for example, the captured amount of carbon dioxide. According to The developers explaina 50/50 mixture of the compounds can allow to capture a ton of CO2 for every two tons of material. A more harmless waste. The process, as we indicated at the beginning, begins with the separation of water molecules. This generates, in addition to the ions used to unleash the subsequent chemical, hydrogen reactions. This gas is not only harmless but can also be used as an energy reserve. Of course, because electricity is part of the manufacturing process of this material, it must be taken into account that the net emissions of its production will depend on the mix energetic. That is, if the energy used in the process emits CO2 that is not captured, part of the capture would be lost. Another detail to keep in mind is that a good part of CO2 emissions associated with cement production They are generated at a different stage of its manufacture, when the sand is crushed with the limestone and heated at high temperatures capable of decomposing calcium carbonate. This problem occurs if the material is used in the creation of the cement and not when it is mixed later with it in the production of concrete.
