This man is the first person who flies to space without revealing his identity. They haven’t taken to find out who it is

by

Six people traveled yesterday to the Blue Origin suborbital rocket. One was Jesús Callejathe first television presenter that crosses the line of Kárman as part of the filming of a documentary. In the same ship another five people flew. Four of them, millionaire businessmen and executives who had paid for the flight. The sixth crewman was an anonymous person. Was An anonymous person because on the Internet there are difficult secrets to maintain. Context. They are already going 52 people That they fly to the space with Blue Origin since Jeff Bezos, the owner of the company, premiered the small New Shepard rocket with his brother Mark, the aviator Wally Funk and the young Oliver Daemen (the oldest woman, with 82 years, and the youngest man, with 18, in crossing the border of the space). Taking into account that just 719 people have traveled beyond the 100 kilometers of altitude, Blue Origin’s space tourists begin to be a multitude in the select club of people who have gone to space. With its flights for millionaires of just 10 minutes, the New Shepard rocket has a growing record of records: the oldest man (William Shatner), the first Mexican (Katya Echazarreta), the first Portuguese (Mário Ferreira), etc. What they had not had until now was an anonymous passenger. The first suborbinaut without name. Of the 719 people who have flown to space so far, none had done without revealing their name. The astrophysician Jonathan McDowell knows it well, who maintains a database of all space flights in historystarting with Yuri Gagarin on April 12, 1961, and Alan Shepard, on a suborbital flight, 23 days later. When McDowell went to update his database with the crew of the NS-30 mission of Blue Origin, he decided not to settle for the unknown of the sixth traveler (the first stain of the history) and asked his followers (in a tweet now erased) if they could find out who he was. Most of the answers reproached McDowell having used their influence to try to expose a person who wanted to remain anonymous. Others They wondered If it could be the camera of Jesús Calleja (but why hide his identity, then?). Until, finally, one of McDowell’s followers found who he was. R. Wilson. Blue Origin had diligently complied with his client’s desire. The mysterious traveler He went out to face discovered In the official photos and videos of the mission, but on the web, on social networks, in the press releases, in the retransmission of the launch, Blue Origin only mentioned the first five passengers with name and surname, adding: “and a sixth crewman whose name has not been revealed.” What did not help the man to preserve his identity was to have his initial and his last name embroidered in the space suit: R. Wilson. However common the last name Wilson was enough to French YouTuber Ufotinik He will find his full name and news about him on the Internet. An Australian cryptocurrency. Jesús Calleja mentioned in an interview that an Australian friend had done on the mission. Perhaps he refers to Russell Wilson, founder of the Coinspot cryptocurrency exchange platform, based in a modest Melbourne building. According to a report of 2023 of the Daily MailWilson leads a discreet life in the city’s suburbs, although he has paid 538 million dollars in dividends. The report includes a photo of the businessman, who already maintained a low profile and avoided public attention, delegating media appearances in his executives while led the company from anonymity and following strict security protocols. He failed to maintain anonymity then, nor has he achieved it on his trip to space. But McDowell’s efforts for not letting an entry into its database only reinforce the initial idea of ​​this article: space tourists are beginning to be a crowd in the select club of people who have gone to space, so we will see more and more eccentricities above the karm line. After all, career astronauts, those of space agencies, are officials chosen and formed to the extreme for a single thing: act according to the protocols and be predictable in any situation.

There are people putting toilet paper in the fridge. What does science say about the trick to eliminate bad odors

by

If one day we open our fridge and encounter A roll of toilet paper insidewe might think that we live with a very clueless person who has confused the fridge with the bathroom closet. We would probably be wrong: There is a reason To put toilet paper in the fridge. The question is whether it is a good idea. The first question that comes to mind is: why? What is sought with this strange idea is to reduce the bad odors that are sometimes presented in our fridge. The “trick” also promises to extend the life of our food and even save energy consumption. Ok and work? Although we have not tested the method, the toilet paper could help us Eliminate bad odors from our fridge. Although there are some issues to consider to go for our paper rolls. The logic behind is that the toilet paper can absorb moisture (this paper is absorbent so it is capable of collecting environmental humidity by dehumidifier) ​​and with it the bad smell of our fridge. It would also help to preserve food better, reducing the rhythm to which they spoil and avoid passing that emit new bad odors. Insert paper into the fridge is one of the “tricks” that he proposes The Food Security Service of the United States Department of Agriculture (USDA), but not as a way of maintenance but as a way of ending persistent odors in our fridge. In an article dedicated to how to eliminate bad odors from the fridge, the service suggests filling our fridge of Rolled newspaperthen close the door and leave it like this for several days. After taking out the paper, they recommend cleaning the fridge with water and vinegar. Using newspaper has the advantage that this will be a role that will be discarded equally, but it is also an increasingly weird paper to find in our homes. If we use toilet paper we must avoid using paper that we have had stored in the bathroom outside its wrapping since it will have been accumulating moisture and will be more “loaded” from it. Avoiding bad odors It should be noted that the use of paper, whether newspaper or hygienic, is not the first method suggested by the USDA on its page as a way to eliminate bad odors from our fridge. The first thing to do in these cases is to eliminate any food spoiled that could be causing bad smell. Then, remove all the trays and drawers from the fridge and clean them with soap and water. Then we can give them a bath with a “sanitary solution” making a tablespoon of bleach not aromatized in 3.5 liters of water. Also use this solution to clean the interior of the fridge. After that we must leave the appliance open for a quarter of an hour. Appliances manufacturers are also A good source of information when looking for tricks that allow us to improve our use of the devices that manufacture. These methods include several cleaning products, we must be aware of Do not mix them. For example, mixing bicarbonate and vinegar will cause the different levels of acidity of the products to be annulled since vinegar is acid, while bicarbonate is a base. Mix vinegar and bleach, on the other hand, It is a risk to our health since the mixture will release harmful gases. Interestingly, this “trick” could help us save energy. Every time we open the door of the fridge we can generate air currents that introduce warm air from abroad into the fridge. When we close the door, the fridge must renounce this air, spending more energy. The more full the fridge is, the less air it can be exchanged with the outside, so a fridge fills less energy. If we put a roll of toilet paper (as if we put a brick), the fridge will cool it once alone, and not as many times as we open and close the door. This “trick” can be useful in very specific contexts, if for example we have our refrigerator halfway fill more or less constantly.

This tells us the DGT about getting the card without a teacher

by

The DGT studies changing the self -school system and adapting to the United States. You may have read similar information in recent days. But, the truth is that the DGT has not proposed anything and the decision is not in its hands. So what is happening? There is nothing new. And there is neither date for possible changes nor a road map on it. That is what the DGT has answered to questions from Xataka. The origin of a possible change in access to the driving card is in a proposition that It is debating Europewhere it seeks to facilitate access to cars to a greater number of drivers. This is the last case but it is something that is discussed For almost a decade. That proposal, as we say, continues to debate and would have to continue passing filters that can mold it. That is, it is possible that Europe approaches its way of accessing the driving license to the United States. Or may not. Determined the final text, it would have to be voted and, subsequently, issue a directive that would force compliance. Only in that case. From traffic they also insist that only in the event that the directive was issued, the way to adapt these new demands to the Spanish environment would be sought. However, there is no clear proposal on the table since the text could leave in the hands of the member states Major or lesser wide sleeve to adapt the new reality to its regulations. Taking advantage of the Words of the Interior MinisterFernando Grande-Marlaska, who recently said that the possibility was being valued, some media and users on social networks have raised this whole issue to the news category, noting that the DGT would be behind a change in the system. The CNMC. Grande-Marlaska responses arrived in relation to a report presented by the National Commission of Markets and Competition (CNMC), who bet on opening the hand with the requirements asked for self -schools and turn to a “tutoring” system where a driver can supervise the driving skills of an applicant before facing the exam. They propose, for example, that “the accompanied practices would be compatible with a possible maintenance of mandatory training obligations in self -schools if necessary, for example, establishing a minimum of classes in self -school before the driving accompanied.” A fire. In spite of everything, this report has caused a fire among the self -schools that consider “a danger to road safety” the proposals presented by the CNMC. Álvaro Llamas, president of the National Auto School Association (Anaes) wondered the following: If the objective is to improve the tormation of the applicants, we do not understand that any citizen is considered, with experience, but without training skills (…) and less in a vehicle without double pedal. If there is a sinister, who of the two is going to lace responsible? Who, who will have the tools and control to avoid it? And who guarantees that this tutor will not transfer the applicant for his bad habits and customs at the wheel? What happens in the United States? Depending on the State, Things are slightly different In each place in the country. However, in general, we can say that in the United States it is possible to drive from the age of 14 or 16 (depending on the place) accompanied by a tutor. This tutor offers his experience and warns the future driver. When he feels prepared, he goes to take the exam to obtain a license that will allow him to drive without being accompanied. Step by step. In addition to this change, in Spain the possibility of introduce license B1. This is already active in some countries Of our environment and would allow a 16 -year -old adolescent to access vehicles that do not exceed 90 km/h, a mass that does not exceed 450 kg and a power that does not exceed 20 hp. Measure defenders indicate that it is an evolution of the AM license, which is available since the age of 15 and allows conducting known as “Cars without a card”. They point out that the driver will be more familiar when he can take a license B, which has no power or maximum speed limit and can weigh up to 3,500 kg.

‘Anora’ is the big favorite to take the Oscar for the best film. The problem is that it has the voting system against

by

‘Anora’ starts in the pools as a great favorite to take the main Oscar of the night, the best film. However, The Oscars They are much more than a mere vote that chooses the film of the year: they come into play not only the millionaire advertising campaigns that are talked about so much (which also), but models of mathematical probability and the same voting system, which do not always favor the favorite of the simple majority of academics. The pretty girl. ‘Anora‘It is Sean Baker’s film, an old acquaintance of fans of the independent cinema zone. Some of its previous proposals, such as ‘The Florida Project’ and ‘Red Rocket’they raised praise among the specialized press, but with this story of a young Brooklyn prostitute who lives his own history Cinderella when he knows and marries the son of a Russian oligarch who intends to end romance, has revolutionized the awards season. The film won the gold palm in Cannes and Dos Bafta, was nominated for five Gold balloons And now she is nominated for six Oscar, including best film, director, actress and original script. ‘Anora’, the independent tradition. ‘Anora ‘continues Oscar’s tradition to reward small and modest movies, looking for a quality patina indie that Hollywood industry is excited since the time of The infamous Miramaxand that has made films like ‘in recent yearsAll at once everywhere‘(2022),’Coda‘(2021),’Nomadland‘(2020) or’Parasites‘(2019). The winner of 2018, ‘Green Book’, was only indie in aesthetic terms, but still, is a streak of victories outside the industry that only broke ‘Oppenheimer‘ last year. The numbers speak. In addition to the recent trend of the Oscars, dyed of a certain condescension, to reward independent films, we have the purest mathematics: The Hollywood Reporter used the probability laws To make the calculation and ‘Anora’ was well above its competitors: 52% possibilities, overwhelming the second in the list, ‘Conclave‘, which was left with 15.2%. The reason? The ‘Anora’ awards streak in the Critics Choice, Producers Guild and director’s Guild. Less colorful than the Golden Globes, but according to statistics, infallible when opening via for the Oscar (let’s not forget that on many occasions the voters coincide). Percentages against competitors. These statistics in favor of ‘Anora’ are increased when those same numbers play against their competitors. For example, only seven films have won an Oscar for the best film without having the direction nomination, as happens to ‘Conclave’. ‘The Brutalist‘It is one of the favorites, but never a movie without the SAG prize or An Eddie (The US editors awards) has won the main Oscar. ‘Emilia Pérez’ had everything in favor with the Golden Globes, but Reality has passed over. Already ‘A Complete Unknown‘It has not gone wrong with other awards, but in any other gala the best film has been taken, something that greatly reduces its possibilities. But if everything is in his favor … Ya: Why are the real probabilities of ‘anara’ are smaller than, for example, those of ‘conclave’? The voting system for best film is called “Preferred System”, and with it the voters are asked to classify the nominated films from the greatest to less preference. If a film gets more than 50% of the votes (something very unlikely), automatically wins the prize. But if not, the following process is carried out: the film with less votes redistributes its ballots among the second most voted film of the members who had placed it in number one. It is done with all, until a film exceeds 50%. The terrible consensus. The idea with this system is to reward the favorite film by consensus, one that most of the members of the academy would consider their favorite. The result is that the films that go to the extremes are less likely: ‘Anara’ will be the favorite of many, but because of their theme and indies modes, it will also be among the least favorite of many others. This system rewards, in effect, the consensus, which is another way of saying that it rewards the middle ground. In that sense, it is ‘conclave’ that will benefit: a very little annoying movie, which many will have liked, but few have liked very little. The danger of controversy. Something similar to ‘Anora’ will happen to films such as ‘Emilia Pérez’, one of the favorites before the successive bombings of Karla Sofía Gascón. EITHER ‘WICKED‘, which belongs to a genre with as many defenders as detractors. Or, of course, ‘Dune 2‘ either ‘The substance‘, which only to belong to the categories of horror and science fiction will receive very low scores of the less daring faction of academics. In that sense, and except for exceptions (it is clear that ‘anora’ has possibilities, despite everything) the Oscars almost always reward the low risk. Nothing new under the sun.

The FBI, the Pentagon and the NASA have ordered to keep the secret

by

Elon Musk announced from Your profile in X that Doge would send an email to all federal officials to whom they had to respond without a period of less than 48 hours. Otherwise, they could occur like automatically fired. Those responsible for these agencies have already been adopted a decision in this regard: to ignore that email. Musk mail and its strategy. According to published Fortunein the issue of mail, aimed at the more than 2.3 million federal employees, you could read: “What did you do last week?” Inside, Doge urged officials to indicate what they had been working on during the last week. If they did not receive an answer, Doge would assume that this official was no longer active, which would imply his automatic resignation. It is not the first time that Elon Musk and Doge uses a intimidating email as a channel to fire employees. In 2022, when the millionaire took control of Twitter also sent emails to employees urging them to resign If they did not agree with the new policies that established upon arrival. On that occasion, the result was the dismissal From the Twitter template, although the play did not always go well. NASA is not in a hurry. At least two government agencies have openly challenged Doge’s indications regarding the dismissal mail. NASA was the first to respond: in an internal statement to which It has had access Bloombergthe managers of the space agency urged their 17,000 employees not to respond to that email until they had a guide on how to respond to ensure that “all the rules are met.” Those responsible for the agency warned of “pausar any response to the email in question, so as not to reveal confidential or prior information to decision making to unknown recipients”, since doing so could incur a leak of reserved information. They also exempted responding to Doge’s requirement to all permission employees or who were on vacation, because it is not among their obligations to review the mail these days. The FBI and the pentagon on the spam tray. The managers in charge of supervising the officials of the Pentagon and the FBI have not been very supportive to immediately respond to Doge’s mail. According to confirmed Associated Press, Kash Patel, the newly appointed director of the FBI said that “the FBI, through the director’s office, is in charge of all our review processes, and will carry out reviews in accordance with the FBI procedures. When when And if more information is required, we will coordinate the answers. For their part, from the State Department, Defense and National Security, they were much more direct ordering all their employees to ignore Doge mail, ensuring that the State Department would respond for its workers. “No employee is obliged to inform about his activities outside the department’s command chain,” wrote Tibor Nagy, interim State Undersecretary to the officials in charge. The reasons are very similar to those argued from NASA: there is a high risk of revelation of secrets in those answers. 8.5 million by mail. According to estimates of Fortunethe “drag fishing” maneuver that Doge has used when sending that email will involve an approximate loss of 166,500 hours of work time of the officials, taking as reference the five minutes that Elon Musk assured that would take it to answer it. All those hours employed in justifying the work of officials represent a disbursement of 8.5 million dollars for state coffers, taking into account that the average salary of public officials in the US is 106,000 dollars a year.

If you have ever wondered what would happen if 99% of a country will run out of electricity, Chile has lived it in their flesh

by

99% of the population of Chile remained in the dark. A failure in an electric transmission line caused the biggest blackout from the country in 14 years from 3:15 p.m. until after 23:00 hours. Short. Chile has seen the electricity supply interrupted in 14 of the 16 regions, from the Arica northern to the southern of the lakes in an extension of more than 3,000 kilometers that the nation travels, According to the National Disaster Response Service (Senapred). For eight hours the Chilean country was without light or connection and until midnight did not return, so the government authorities They had to decree The state of emergency and a curfew (between 22.00 and 6.00 in the morning on Wednesday) and convene the disaster risk management committee (Cogrid). The chaos. The blackout that surprised at noon generated a huge circulatory chaos, prevented banking, financial, mining and commercial activity. In addition, it put hospitals and other essential services at risk, and has already been reported at the time of writing this note The death of three electrodependent people. On the other hand, the images of the Metropolitan Region Metro Without light and People returning on footthey are already viral in different social networks. To this media have confirmed people from the Bío Bío region, Valparaíso and the city of Santiago de Chile who had to send SMS messages to communicate, the information came through the radio and the little internet (it was intermittent) reached them to use to use The X app (old Twitter), since it was the only one that worked. Regarding the coercive measures of the government, it mobilized thousands of security agents of the Military Police of Carabineros and the Investigation Police (PDI), According to the Undersecretariat of Defense. For the moment There is no record of acts vandalism or serious accidents, but the national air traffic with delays and agglomerations has been affected. The blackout. The president of Chile, Gabriel Boric, He went to the country at 10:00 p.m. from the Palacio de la Moneda by contingency before the power of electricity supply. In this speech to the population, Boric explained that the blackout was the product of A fault of the Isa Interchile company and there was a massive cut in almost the whole country. From the National Electric Coordination (CEN) they reported that the interruption of the electricity supply was produced by a disconnection of the 500 kV transmission system in the North Chico. Through this situation, the service recovery plan was activated to reestablish electricity, but it did not begin to reach up to 10 p.m. and after four attempts, they had not succeeded. The president of the Board of Directors of the CEN, Juan Carlos Olmedo, confirmed that disconnection It was due to “an unwanted operation in the protection and control systems of the line (which the Isa Interchile company manages).” And he explained: “The electronic systems did not operate the way it should have operated.” The vulnerability of the system. Isa Interchile, a subsidiary of the Colombian company Isa, plays an important role in electric transmission in Chile, being responsible of infrastructure such as the New Maitencillo Line – New Pan of Sugar. The electrical system in Chile is composed of different private companies that generate and distribute, but a failure in these infrastructure can affect the electricity supply nationwide. The recent blackout has shown The vulnerability of the electrical system Chilean, no It is obsolete. However, when concentrating into a few hands and an interruption in a key infrastructure can generate chaos nationwide, highlighting the need to reinforce Resilience and diversification in the country’s electrical system. Affected a pillar of the economy. The world’s largest copper mine, hidden from BHP, ran out of electricity, confirmed to Reuters. Also the state copper mining company Codelco confirmed in a statement to media That all their mines were affected, leaving the largest, the Lieutenant and Chuquicamata, without electricity, while the smallest mines could partially operate using support generators. Similarly, the Antofagasta Minera was able to continue working. A day after the blackout. Recently, Interior Minister Carolina Tohá, has announced at a press conference that the government has raised the state of exception by catastrophe, together with the curfew. However, the minister explained that the uprising of the measure “does not affect the regions of the country in which we have a state of emergency exception, particularly the Araucanía region and much of the biobío, which are with an emergency state by security reasons, this does not affect the deployment of military personnels that we have on the border (north). ” Image | Pablo carved Xataka | There are so many Australians with solar panels in their roofs that the electricity grid has been one step away from the abyss

How worried we should be because the earth’s crust is cracking

by

The geography of India is very influenced by the tectonic plate associated with this subcontinent. This is remarkable in places like the Himalayas, the result of the clash between this plate and the Eurasian. However, dynamics change and plates can disintegrate. Horizontal cut. A New hypothesis On the interaction between tectonic plates, it could yield new doubts about the geological process that gave the Himalayan mountain range the highest peaks in the world. It would be an interaction never designed before: the horizontal break of a tectonic plate. The clash of an era. The mountain range between the heart of the Asian continent and the Indian subcontinent was formed between 40 and 50 million years ago when the Indian continental plate crashed into the Eurasian plate. The accumulation of the volume of these two masses of land implied that the earth’s crust was becoming thicker in this region, creating a colossal mountain range. This is a still unfinished process since the Indian plaque continues if it derives north, accumulating more mass and raising even more summits such as Everest. The mountain range grows at the rate of one centimeter per year. The subduction of the plate. So far the dominant hypothesis about what was happening underground in that border region contemplated the idea that the Indian plaque was undergoing a subduction process. That is, the Indian plaque was immersing under the Euroasyathic. At the same time, the Eurasian plate is transformed, folding and increasing in thickness, generating a region where the earth’s crust is more bulky. The new hypothesis Contemplate a different scenario. A new hypothesis. In it, part of the Indian plaque would be suffering a subduction process, but not all. As a knife cutting a bread bar to prepare a snack, the eurasian plate would be cutting in two, horizontallythe Indian plaque. This would imply that it would be part of the latter that would also be in the superficial zone, wrapping the Eurasian plate. Those responsible for this idea presented their defense at the conference of the American Geophysical Union and Through an article In the repository Ess Open Archive. Two ways to break. The rupture of a tectonic plaque is not a phenomenon at all strange. An example We can find it in Africa and its tectonic plate. The African continent as we know it will disappear in a few million years when a fracture divides it by two throughout a North-South Axis that will separate the easternmost area from the continent from the rest of Africa. This is the conventional rupture that allows tectonic plates to reorganize thereby causing continental drift. A drift that still keep many secrets That we are just beginning to discover.

China prepares to lead the manufacture of chips for advanced weapons

by

China monopolizes gallium production. In fact, Up to 2022 monopolized 98% of the world gross Gallic, and this figure presumably has barely varied since then. For the country led by Xi Jinping This metal has a strategic value comparable to the one for the US due to its potential in military applications. And, in addition, Gallium export control allows China to respond to the sanctions to which the US and their allies are subjecting this Asian country in the scope of the semiconductor industry. Gallium is a very special metal. Its physicochemical properties make it suitable to be combined with other metals with the purpose of manufacturing a special type of integrated circuits called broadband semiconductors. These chips have three properties that make them very valuable to intervene in the manufacture of Advanced military teams: They support voltages, temperatures and frequencies higher than integrated conventional silicon circuits. During the 70s the US Advanced Defense Research Projects (Darpa) He dedicated many resources to the development of semiconductors in which Gallium was involved due to the potential he had in military technology projects. He Gallium Arseniuro (GAAS) played a fundamental role in the development of the global positioning system (GPS), and also in Radark tuning and precision weapons. China has taken a very important step forward Currently, Gallium Nitruro (GAN), which also has Darpa’s backing, is being used to make state -of -the -art radars that are capable of accurately identifying smaller, fast and numerous objects at more distance. Each of these radars incorporates several thousand chips in which the gallium intervenes. Everything we have just seen invites us to reach an obvious conclusion: Gallium is an essential metal for the US. But this country is not the only military superpower on the planet. The Chinese army and research institutions have been working with Gaul for many years and developing technologies that allow you to use it Third generation advanced semiconductors. As we have seen, China has Gallium in abundance, but producing integrated circuits with this metal is not easy. Neither for the country led by Xi Jinping nor for which Donald Trump is currently governing. Modifying electrons energy levels, it is possible to accurately control climbing and reduce defects To manufacture gallium nitruro, silicon and sapphire substrates are often used, but the effectiveness of the processes used so far was moderate because the hexagonal atomic structure of the GAN causes the appearance of a defect known as climbing. In broad strokes this curious phenomenon triggers the displacement of groups of atoms in a certain region of the crystal, which affects its structure and reduces its properties. In fact, GAN manufacturing defects cause electric leaks, reduce their thermal stability and reduce the performance of semiconductors. Until now the researchers who work with GAN had difficulty understanding why these defects appear in the crystalline structure of this material. And also to deal with them. But the team of scientists led by Professor Huang Bing at the University of Beijing (China) has identified the cause which triggers the production of defects during the growth of the Gan Crystals. What these scientists have discovered is that modifying the energy levels of electrons it is possible to accurately control the climbing and reduce defects. “Traditional strategies to avoid defects include the use of different substrates and the adjustment of crystallization temperatures, but these approaches only address symptoms, not the cause,” Professor Huang Bing explained. If China manages to get this research from the laboratory and bring to production chains this technology will have the ability to manufacture cheapest GAN -GAN semiconductors, of more quality and a much larger scale. And at this juncture it will not be unreasonable to anticipate that it will be done with the leadership of the application of 3rd generation semiconductors in the military field and 5G technologies.

convince us that the company has not lost the AI ​​train

by

Panos Panay, dressed in rigorous black, launched himself to give his first great Keynote as an Amazon employee. Not long ago, but with Microsoft where I was the head of the hardware divison. Your mission here is even more complex, because Try to show that Amazon has not lost the AI ​​train. And to achieve this, he was in charge of presenting the new version of Alexa. A supervitaminated with AI. During the presentation Panos Panay tried first to defend Alexa’s legacy, a voice assistant who according to this manager attracts millions of new customers every month. It is a unique statement, especially when it is evident that in recent times that technology has been far behind the modern models of generative. Alexa: 11 things we can do with Alexa and 5 that still does not For Amazon it was not enough to integrate a model of AI capable of explaining with a synthetic voice how to make a recipe. “You will not buy the ingredients and will not send an invitation to your friends for dinner. A chatbot of AI does not take us to what is our vision for Alexa,” he explained during the event. AND that’s where Alexa+ arrivesAlexa’s new version. An AI technology with which Amazon wants to change everything: we are facing an agthic that is capable of doing things for us. Not only to answer questions, but to take advantage of your integration with other devices and applications to perform actions. In the demo shown by Panay Alexa made a reservation in a restaurant, sent a message to the kangaroo and added everything to the calendar. Not only that: it was also shown as Alexa+ is now much more conversational – here the new models and the recognition of natural language have done a good job – and is able to interact with the home automation of our home, for example. In his official statementAmazon describes Alexa+ as smarter, conversational, personalized and capable of “doing things”, that is, completing tasks. In many cases, completing these tasks will make it necessary to give access to our data – you, contacts, information with which we want me to work – to this model of AI. According to Amazon, Alexa+ has been trained so that he is able to recognize the tone to adapt to conversation. If he sees us agitated, for example, he will try to calm us down – he who noticed in the demo of Panos, for example. There is another important element in that interaction. Alexa stores and remembers the data you are giving to be able to use them in the future. For example, user restaurants preferences or tastes about certain dishes or ingredients. In the demos it could be seen how the interface of the connected screens Amazon Echo has undergone important changes. For example, it shows an animation at the bottom of the screen when “thinking”. Something since it is almost standard and we have seen in Gemini or Apple Intelligence. There are more animations to represent that Alexa is in action, and Amazon calls them “Alexicons”. Home automation is one of the areas in which this type of interaction with AI is enhanced, and Amazon has created a specific widget for home automation in the interface of its smart screens. Natural language – to speak as we would normally, but with these devices – is the focus when controlling all kinds of options and actions. In development …

There are people convinced that in 2030 we will achieve immortality. These are your arguments

Live more and live better, but above all live more. Longevity is the obsession of many, including some “futurologists” who believe that eternal life (understood as the end of deaths due to natural cause) is close. Objective 2029. As close as This same decade. Before even its end, to be exact. That is the forecast of Google and “futuristic” Ray Kurzweil’s exingender. This was what I pointed out a few months ago In an interview For the company Bessemer Venture Partners. This raises some doubts, as this arguments based on this notion and if we are close to getting out of death indefinitely. In the interview, Kurzweil expressed it as follows: “Science advances and is healing several diseases. You are receiving on average about four months a year (…) however, scientific research is also in an exponential curve. By 2029, you will have received a whole year account. So you lose a year, but you receive a year back. ” “Exhaust speed ”. Kurzweil’s idea revolves around Longevity escape speed concept. In physics, the exhaust speed is a speed that allows us to counteract the gravitational pull of a body and boost away from it thanks to the simple inertia. In this context, the escape speed means something different, which does not lead us to escape something physical but to get away from death from death. The idea is simple, and that is that the increase in life expectancy grows exponentially until it reaches a point where this life expectancy increases in more than a year. Thanks to advances in medicine and other fields, life expectancy has been significantly increasing throughout the world, but, at least for now, indefinitely prolong our life expectancy looks like a simple chimera. Arguments For a short time, if we trust the Kurzweil arguments. The main argument is the rapid advance of contemporary medicine. Medical advances have allowed us to overcome numerous infectious diseases through treatments and vaccines. Kurzweil himself puts as an example the speed with which the Covid vaccine (obviating perhaps the titanic development effort, which was also based on previous works in immunization and genetic). However, it is also true that we continue advancing a lot in the fight against diseases such as cancers. We are even close to Replicate technology which gave us the Covid vaccine in the fight against some tumors. On the other hand, diseases closely linked to age such as Alzheimer’s or Parkinson continue to be a challenge for scientists who still seek to understand the causes of these disorders to combat them effectively. Not just health. The increase in life expectancy is not only limited to the health field. Our world is safer than it was in the past. Transport is safer than a few decades ago, less frequent wars, and violent crimes occur to a lesser extent. These factors have also contributed to the increase in life expectancy and is likely (not sure) to continue doing it in the future. Not so fast. There are those who believe that we will reach the exhaust speed soon without reaching Kurzweil’s optimism. For example, George Church, a genetic expert at Harvard University that indicated that, perhaps throughout our lives, we can reach this evolutionary point. A little more optimistic than Church, Aubrey de Gray, president of the Longevity Escape Velocity Foundation, proposes that it will be throughout the 2030s when we reach it. Will it arrive? There are many reasons to be skeptics, not only with the ambitious Kurzweil agenda, but with the very concept of escape speed of longevity. As we indicated above, there are reasons for some skepticism. For example, the fact that advances in a disease do not imply advances in others. Even cancer is so varied that it implies that, while some are perfectly treatable, others still represent a huge threat to our life. Infectious diseases represent another stumbling block: although we had advanced a lot in the creation of vaccines and antibiotics, the latter are losing efficacy by leaps and bounds before the arrival of the “superbacteria.” Neurodegenerative diseases also remind us that not only just dodge death, while we do not improve our quality of life in the last stages of our life, these improvements will be little.
