shadows

lights and shadows of one of the most outstanding foldings of the year

by

Take the step to a folding phone or not? That is the question that many people ask themselves when looking for a device that break with the schemes that have dominated for years. But the answer is not so simple. Before making the decision, multiple factors come into play, from the available budget to the resistance and performance of the phone, to its real usefulness on a day-to-day basis. In a new 24/7 Xataka YouTube channel We put one of the most outstanding folding products of the year to the test. We talk about Samsung Galaxy Z Fold7a proposal that, as we already mentioned in the first impressions and later in the reviewstands out for its solid arguments. Now, once the initial illusion is over, an inevitable question arises: is it still a good mobile phone over time? To answer it, Ana Boria has tested it for you for almost six months. Samsung Galaxy Z Fold7, is it still as good after months of use? The first great rating from our companion comes after a month of use. “I can’t fault its performance.“, he says. It is not a gratuitous statement. Much of the merit lies in the Snapdragon 8 Elite accompanied by 12 GB of RAM that we find inside. Performance is up to any day-to-day demands. Of course, in the video it is also clear that not everything is perfect and some shadows begin to emerge, one of them quite unexpected. Already in the fourth month with the Samsung Galaxy Z Fold7, Ana launches an assessment that points directly to one of the aspects that Samsung had tried to correct with this model. “Although we already have a much more normal format than in previous generations, for my taste it is still too vertical,” he says. It is worth remembering that the South Korean company defends that, when it is closed, the experience is very similar to that of a mobile phone in conventional bar format. Another key point for many users is autonomy. And one of the most reliable ways to measure it is to observe its behavior after months of real use. Ana shares her experience with the telephone in different day-to-day scenarios. “I wanted to tell you that I am quite surprised with the battery of this foldable“, he comments. The question remains in the air: has it really met your expectations? The last section of the experience focuses on the photographic section. Here Ana puts the cameras to the test during her vacation in Japan. “When shooting with the main sensor we get images with good dynamic range, good sharpness and a very accurate white balance,” he explains when talking about daytime photos. It also leaves a particularly relevant assessment on the performance of the cameras in night conditions. As we say, Ana’s complete experience after all these months with the Samsung Galaxy Z Fold7 It is now available on YouTube. We invite you to watch the video and leave us your comments, both in this article and on our channel.

In case there weren’t enough AI companies. Jeff Bezos has just returned from the shadows to raise another one, according to the NYT

by

After leading Amazon for almost three decadesJeff Bezos left four years ago the highest position in the company that he created to focus on other projects. Personally, His wedding to Lauren Sánchez made headlines; professionally, His involvement with Blue Origin has been constantat a time when the space company rivals SpaceX like never before. At 61 years old and in a comfortable stage of his life, few would have imagined that Bezos would return to the CEO chair of a new company. But in Silicon Valley, where withdrawal is rarely final, nothing can ever be closed. The case of Eric Schmidt, former CEO of Google, is a good reminder: At the age of 70 he assumed the presidency and executive direction of Relativity Space. And now, according to The New York TimesBezos is back. Bezos returns to an operational position with a powerful bet The tycoon, who as of this writing appears as the third richest person on the planetaccording to Forbeshas set his sights on a new project. We talk about Project Prometheusa company that emerges with financing of 6.2 billion dollars, much of it contributed by Bezos himself. And, of course, it is a bet on artificial intelligence. The company appears at a time when artificial intelligence is experiencing accelerated expansion. It is no secret that the environment is dominated by names like Google, Meta and Microsoft, along with references such as OpenAI and Anthropic. Added to this dynamic is a growing number of startups seeking to differentiate themselves with more specialized proposals. That Bezos adopts an operational role in this context reinforces the relevance of the project and positions it from the beginning within the competition for the most ambitious advances in the sector. As detailed by the American newspaper, the first steps of Project Prometheus have not been particularly visible and there is still no confirmed date for the start of its operations. However, the type of technology that is being developed is known, focused on applying AI to engineering and manufacturing challenges in areas such as computing, aerospace and automotive. It is an approach that requires teams with high scientific specialization. For now, the location of the company has not been made public either, a fact that remains unclear. The company is focused on applying AI to engineering and manufacturing challenges in areas such as computing, aerospace and automotive. The sources consulted point out a relevant detail: Bezos returns to direct management by becoming co-CEO of Project Prometheus, a role that he had not held since leaving Amazon. Share that responsibility with Vik Bajajphysicist and chemist with extensive experience in applied research. We are talking about a profile that worked alongside Sergey Brin at Google X and later participated in the launch of Verily, Alphabet’s laboratory dedicated to life sciences. Project Prometheus is part of a broader trend within the sector. A growing number of companies are applying artificial intelligence to tasks linked to the physical world, from robotics to drug design or scientific research. This year, several researchers from companies such as Meta, OpenAI or Google DeepMind have abandoned consolidated projects to found new initiatives, such as Periodic Labsfocused on accelerating discoveries in physics and chemistry. It is in that environment where Prometheus begins to place itself. The interest in applying artificial intelligence to the physical world also responds to an important technical difference. Large language models learn from huge amounts of digital text, from articles to technical documentation. According to The New York Times, the new approach goes one step further: systems that can also learn from real experiments, run by robots in automated laboratories. Initiatives like AlphaFold have already demonstrated advances in areas such as drug design. It’s on that frontier, where software meets physical experimentation, where Prometheus wants to compete. The implementation of the project is also reflected in your team. Project Prometheus, sources say, has incorporated nearly a hundred employees, including researchers from companies such as OpenAI, Google DeepMind and Meta. This movement confirms the technical ambition of the company and the intention to advance quickly in a field where talent is decisive. Bezos’ decision to return to an operational role also comes at a particularly competitive time for the industry, adding even more attention to the company’s next steps.

Spain has a rail giant in the shadows. And just achieved the “contract of the century”

by

If you have traveled to Belgium, the SNCB application is likely to have downloaded to move from one city to another. It is about ‘the Renfe‘Belgian and, a few years ago, They announced that they were going to renew 50% of their fleet from here to 2032. The interesting thing is that it is an operation of 3,400 million euros that has not fallen to anyone: it has done so in a Spanish company called CAF. And if you are wondering what diantres is caf, you are in your entire right, but you will surely have mounted on one of its trains. “The contract of the century”. In a release of CNCB, the operator detailed the pre -agreement reached with the Spanish, something that replicated own CAF detailing that the initial commitment of the same will be 1,695 million euros. This includes the development, manufacture and supply of 600 am30 trains (interurban trains with integrated motor and autonomy by battery when operating in un -electrified lines) with a total of 170,000 seats, although the initial commitment is 1,695 million euros for 54,000 places. The proposal of CAF has had to compete with other manufacturers, such as the French Alstom that argued cheapest prices, factories in Belgium and that local industrial promotion. Everything is not closed, since although CNCB has opted for the Spanish, political interests come into play in something like that. There is a debate around the firm and, for example, as we read in Basque chroniclea deputy of the Belgian Party Staf Aerts has discredited to the company, indicated that CAF is collaborating to create a subway line from Jerusalem to the Palestinian territories occupied by Israel ” As we say, it remains to be seen that the agreement is finally closed, but by its magnitude, there is already talk of the “contract of the century” of the railway sector, with obvious consequences In the CAF portfolio. Centenaria. This news, because of its magnitude, has jumped to the first flat of numerous national and European economic newspapers, but the great question we could have is … what is CAF and why it is so important. CAF responds to ‘Constructions and Railroad Assistant‘And it is a company that was born in 1917 in Beasain, Basque Country. It was founded on workshops that already existed since the nineteenth century and from the beginning it was dedicated to the manufacture and rental of wagons, as well as other elements for rail transport. And in this more than a century, it has become one of the larger companies in the country. The Oaris World jump. They were developing their business within our borders, providing Renfe trainsbut in the 90s, they consolidated the international leap by operating more firmly in other countries thanks to the opening of about thirty subsidiaries. In Spain they have, above all, high -speed trains of variable width manufactured next to the ALSTOM itself, as well as electric and diesel trains for regional services and Renfe vicinity. However, much of your order portfolio It is for export. They have manufactured units for cities such as London, Brussels, or Sydney, as well as the Santiago de Chile and Mexico Metro, light trains for US cities such as Boston or the Oaris: High speed trains (up to 350 km/h) that form the backbone of the Norway rail network. And, to meet the needs, they have gone Opening factories all over the world. Why the mystery? In spite of everything, we do not know too much CAF beyond their area of direct influence (where they have the factories and hire employees) it has all the meaning of the world. Before we talked about Talgo, also a historic rail that not only stood out for their trains, but to baptize vehicles with their own name. Go up to Talgo It was synonymous with getting on the train just as asking for a Kleenex is asking for a handkerchief or, in some countries, playing “the play” is playing any game console in general. In the case of CAF, the same did not happen and, although it is an industrial pride in Euskadi and very recognized among experts around the world, its business has remained “in the shadows”. They operate mainly in the B2B sector, which implies work for large operators both public and private and not for the final consumer, and do not baptize their creations such as “CAF”, which keeps them in an unknown position for the general public. However, the last decades have grown, especially abroad, and with contracts such as the one achieved in Belgium and the jump to large media, it is more likely that the name ‘CAF’ sounds more and more.

Sam Altman is building an empire with Openai. One with some lights and with many shadows

by

Sam Altman is a master of empathy. He listens to you as if you were the most interesting person in the world, learn what he needs about you and his speech fits what you want. And so convince you. It is one of the first conclusions that Karen Hao arrives in her new book ‘Empire of ai’. In it we are narrated OpenAI origins and its evolution Thanks to hundreds of interviews with employees and former employees of the company, in addition to those made to professionals from other companies in the artificial intelligence industry. Altman is loved or hated, there is no middle ground We actually know the story – in Xataka We have been Speaking of Openai – but what Hao proposes to us is a visit to what happens behind the scenes, contributing many details that help us understand the past, present and perhaps the future of the company. Many of those details focus on the figure of Sam Altman, which does not go especially well stopped. Brilliant as a seller of apparently impossible projects, Altman is sparse in words in his communications with other colleagues. Write emails with a single word, “Meet”to arrange appointments, and sometimes use a simple “?” Because who writes less seems to win the game. Of that Jeff Bezos knows a lot. That, of course, when I wrote something, because according to Hao Altman leaves almost nothing written. Everything is verbal, something that allowed him to argue after people did not remember well what he had talked to him. The opinions of those who talk about him in the book are significant. One of them commented that “it is so attentive. But partly uses it to find out how to influence you in different ways.” Others commented how Altman avoids expressing negative emotions and also confrontation. He dodged the word “no” in conversations with other people. “Others began to see him as someone diabolically capable of beating situations in his favor.” Ilya Sutskever, one of the co -founders who came after her differences with him, left A disturbing statement: “I don’t think Sam is the right person to be the one who has your finger on the AGI button.” OpenAi lives his own ‘Game of Thrones’ Paul Graham, his mentor in Yc Combinator, left two citations that leave a clear idea of ​​what Sam Altman is like. In the first commented that “you could throw in parachute to an island full of cannibals, return in five years and he would be the king.” In the second reinforced That vision of his protégé: “Sam is extremely good when it comes to becoming someone with power.” It is something that Hao often mentions in the book and that makes it clear that Altman does very well one thing: win the battles for power. There are two clear examples, also known. The first, when managed to snatch Musk The direction of Openai at the beginning of that unique adventure. The second, when After his scandalous dismissal He returned more force than ever as the almighty CEO of OpenAi. Those two moments in the history of this company are actually reflecting what happens in any empire: the view seen is usually impeccable, great, powerful. The hidden face is full of internal conflicts and wars, battles for power, and rivalries and differences of criteria that end badly. In all these battles an Altman was imposed again and again that according to Hao used a singular tactic: he changed his speech according to the interlocutor. What he had told A was often what he had told B. The problem arose when A and B were talking about what Altman had told both of them. That also happened with Openai’s original vision. Created as a laboratory for the development of a beneficial for the world, The approach would change soon. To share knowledge and details about its models, the company became a secretism bunker. Seeking to be the AI ​​monopoly Like Oppenheimer, Altman Believe That “technology occurs because it is possible”, and like others before him – including one of his mentors and friends, Peter Thiel – his goal (such as his competitors, of course) is clear according to Hao: What he wants is to create an AI monopoly. We have seen that with the evolution of their models, increasingly powerful, and that They were there to earn money. That was the vision that has ended up winning. The other, to try to develop a safe and “aligned with the objectives of the human race” has been in the background. In fact Hao reflects it well in the book. If Openai is leading the AI ​​career today it is not only for having been the first to launch a chatbot like Chatgpt, but for its apparently disproportionate climbing. He has invested more than anyone from the beginning. To start, to capture talent. When the project began to create OpenAi Ilya Sutskever, I worked in Google Brain and was already considered a superlla of this segment. The rest of the founding members were offered a salary of $ 175,000 and shares of YC Combinator or Spacex. But Sutskever was offered almost two million dollars annuallybut Google counteroffierted on a bid whose final figure is not known. What is known is that Sutskever ended up abandoning Google to sign for Openai –And then leave it-. In 2016 of the 11 million that Openai spent, seven were for salaries. Initially the company “did not really know what I was doing,” explains Hao: few of the things they worked worked, and those who did it “seemed little original or something someone had already done.” There were more ambitious bets. It is demonstrated by the famous demo of that kind of “GPT 2.5” that made Bill Gates in April 2019. Until then those who investigated the development of foundational models of AI did so training those models with a few dozen gpus. Darío Amodei – who ended up leaving Openai to co -confound … Read more

They are shadows and destroy them is worse than ignoring them

by

“What are those stains in my eye.” That is a question that more than one has ever asked each other. That kind of worms or dust that we see when we are driving and look at the sky, when we see the TV or, even now, looking at the PC or mobile screen, they are not microbes It does not mean that we can see the string theory. They are ‘shadows’ and have a name: Miodesopsia either Muscae Volators (flying flies). They are not a danger, but many of us want to know how to eliminate them because, beyond playing with them seeing how they bounce, they are annoying. The bad news is that we are going to have to endure. Trash. I recognize that the first thing I thought when I saw them was “I have a bug in the eye.” It was already bad luck because it was not one and, in addition, they were in both eyes. Well, they are not bugs, They are shadows. Within the eye we have a gelatinous substance called vitreous humor that, when you get older, makes formations of remains that our own body produces and stay there floating. These waste accumulations project a shadow in the retina, so it is much easier to see the ‘flies’ when we look at a clear background that reflects the light towards our eye. There are several factors that trigger this such as myopia, the aforementioned aging of vitreous humor, if they have operated, diabetes, a sudden ocular inflammation or their own age, but may also appear in young people. Killing Cañonazos flies. There are many factors that can make them appear and the big question is can be eliminated? There are two methods to do so, but the news is not flattering. One of them is through a vitrectomy, surgery that eliminates vitreous humor completely and replaces it with a saline solution. Not only does it eliminate it, but it prevents them from appearing. They can also disintegrate with a Yag laser. The problem is that, with vitrectomy we run the risk of infections or a retinal detachment. And when giving the flies with laser, there is also the risk of damaging the structure of the eye or increasing the risk of glaucoma. And with supplements? Surgery is not an option, although there are private clinics that promote it, but … What happens to supplements? There is also cloth to cut. As mentioned in The Conversation, there are companies like Theia Bio that promote supplements to reduce floats. These supplements contain anti-anti-glycation antioxidants and micronutrients that, according to a study published in their webis able to reduce the size of these floats in 70% of the participants after six months of intake. Here there are a couple of doubts that survive the matter, which minocses. The first is the sample, since it was only 26 people and it is complicated extrapolar with such a low number of participants. The second is that vitreous humor is mobile, so flies are moving and rarely are at the same point, which makes it complex to really measure changes in the number of shadows. The sad conclusion. Unfortunately, those of us who live with Míodesopsias have to get used to them. Yes, it’s a “Are you sad? Well, you are not manual, but there is no evidence that supplements or changes in lifestyle help eliminate these shadows. HE esteem That a diet rich in carotenoids (present in foods such as spinach, broccili, watermelon or grapefruit), as well as the omega-3 is beneficial for ocular health and delaying symptoms of aging in the eye, but in general, not focused on eliminating the floating flies. And the best advice that occurs is … ignore them, not chase them and not be distracted with them. Come on, to live with those ‘bugs’ that one day decided to appear in our eyes. Now, it is also convenient to visit the ophthalmologist if, suddenly, many at the same time appear or make vision difficult, since in that case they could be a symptom of something more serious.
