Alsa has gone ahead of Iryo and Ouigo with a radically different proposal

Alsa, one of the most important companies in the transportation of passengers (if not the most important) is getting back on the tracks. The company, beyond buses, has a lesser-known business that also goes on wheels but off the road. They are their tourist trains. And now the CNMC gives it the go-ahead to operate yet another service. There is no competition. It’s what the CNMC has concluded about the new Alsa tourist train and the possibility of it competing with Renfe on its new Galician route. For regulators, Alsa’s new business “does not affect the economic balance of Renfe’s public service contract.” It is concluded that although Renfe provides services in the same place or to reach the same locations, both proposals “do not compete with each other” since Alsa trains will only be available in summer and are “between three and seven times more expensive” than Renfe trains. For now, Alsa has indicated in its documentation that the tickets will have a price of 17.28 euros while Renfe public services range between 2.51 euros and 5.40 euros. New historic train. During the summer months, Alsa will put into service a new historic train on two Galician routes that will have the following route: Orense – Barra de Miño – Os Peares – San Estevo de Sil – Canaval – Monforte de Lemos Monforte de Lemos – San Coludio-Quiroga – Montefurado – A Rúa-Petín The train, for which specific schedules and details are not yet known, is known as Galaico Expreso and Alsa Rail, the subsidiary that operates its trains, took it out last April from Galician Railway Museum (Muferga), based in Monforte de Lemos. The train was towed by an Alsa machine to pass the exam in Renfe workshops. They explain in The Voice of Galicia that the material consists of two first-class apartment cars, one with restaurant service and a generator van. This last car is property of the museum and the others were donated by Adif with the condition that they be used for tourist services. The Galaico Express. This train that is being reviewed in the Renfe workshops is, as we have seen, a historic one in our country. At the beginning of the last decade, an attempt was made to resume a tourist service with a walk through the Ribeira Sacra that you can see in this link but its use was discontinued in 2011. In his previous attempt To offer this tourist service, the line only made two stops between Ourense and Monforte de Lemos and had a maximum of 200 passengers. Furthermore, they explain in Vigo Lighthousewas an opportunity to revitalize local tourism since train tickets were sold with additional packs to buy or eat at associated businesses. It’s not the first. By no means is this Galician train the first tourist experience in Spain that takes you back to the past aboard trains operated by Alsa. The company has different offers and packs available with trains of all types for prices starting below 20 euros. This is the case of the one known as Blue Train to link Zaragoza and Logroño through the Ebro valley and the 80’s trainwith which you can travel between Madrid and Cáceres and from Cáceres to Valencia de Alcántara. It also has a round trip train to San Lorenzo del Escorial from Madrid known as the Philip II Train and the Train of the Three Wise Men in Madrid and Zaragoza. Other type of tourism. As we said, these tourist train offers in Spain are affordable and are perfect for spending a day with the family. However, there is another type of tourism that has found a rich source in Spanish historic trains. Specifically, luxury tourism. Probably, The most famous case is that of the Transcantábricowhich departs from Santiago de Compostela to reach San Sebastián (with bus routes) and prices that start above 2,000 euros but can reach 10,000 depending on the room. But the latter is not the only one nor the most expensive. Renfe has its Al-Andalus availablewhich in seven days passes through large Andalusian, Extremaduran and Castilian cities such as Cádiz, Seville, Córdoba, Cáceres and Toledo, before arriving in Madrid. Its price, from 5,000 to 14,000 euros. And also operated by Renfe you can get on the Costa Verde Express or the La Robla Expreso. Of course, prepare thousands of euros.

Tesla resurrects the Dojo project with a radically different philosophy

Elon Musk is one of the most important agents in the era of artificial intelligence. Meta, Alphabet, Microsoft with OpenAI and Oracle are prominent names when we talk about gigantic data centersbut if there is someone who cuts the mustard, it is Musk with his xAI company. His Colossus Memphis with 100,000 H100 from NVIDIA to train Grok surprised even Jensen HuangCEO of NVIDIA, but Musk’s goal is not to depend on others. NVIDIA leads the way in chips to train AI (so much so that even Chinese companies want to buy its H200, even if they don’t let them do it). But Musk, like China, wants independence and technological sovereignty, and That’s why he invested in Dojo. It was an ambitious plan to build a customized supercomputer to train the neural networks of the controversial autonomous driving (the FSD). After more than five years in development, 1,000 million dollars invested and key engineers who took the lead drainMusk hill the tap in August of last year. The future was in the AI5 and AI6 chips which were less specific, but could still be used to train the FSD system. However, there is a new twist to this tortilla chip and Musk has decided to relaunch the project. tesla reactive the development of Dojo 3, and it does so by burning bridges with the previous philosophy of this supercomputer. Dojo 3, the heart of Tesla’s autonomous driving Although Tesla has stopped more doubts than anything else these last few years regarding autonomous driving concerned, this continues to be one of the pillars in the company’s short-term strategy. Because they not only have the FSD in their cars, but also in the controversial ‘robotaxis’. Supposedly, it will be this 2026 when Cybercaps will begin to be manufacturedcars that, unlike the taxis that we already see in some cities, will arrive without pedals or a steering wheel. But he doesn’t just want to fuel his cars. Musk wants to make money with softwarebut to have that software, you need to train the system and make it more secure than now. That’s where Dojo came into play. This hardware depended on a very specialized and complex architecture. The D1 chip was the heart of it all, but to achieve high computing power a complex network of thousands of D1 chips mounted in physically separate cases and interconnected by Ethernet cables was needed. It was a very specialized system, but complex to scale without skyrocketing costs. When Tesla turned off the Dojo tap, it commented that its companies would continue investing in the creation of less specialized chips such as the AI5, AI6, AI7 and subsequent ones. More conventional and easier to scale chips. And, precisely, the advances in this architecture are the decisive factor for Musk to revive Dojo. Instead of requiring complex interconnected equipment, Dojo 3 will adopt a modular architecture in which several AI chips can be installed on a single board. Not only is wiring complexity reduced, but heat dissipation is facilitated and the space required for installation is reduced. And, the easier it is and the less space it requires, the more chips can be mounted and the greater computing power. It is not the only advantage. Grouping chips on a single board reduces latency within the chips and improves the power efficiency of the device. To give an example, although they are a headache for expansion, it is the same philosophy that laptops with SSD or RAM memory soldered to the board: Everything communicates faster, more fluidly and requiring less energy to operate. Furthermore, being less specific than D1, xAI’s AIs fulfill both training and inference functions (the Dojo only served for training), which represents cost savings for the company. Now, Dojo 3 will not be a reality immediately. In recent days, Musk has shared via Twitter X the roadmap for its semiconductors. The AI5 developed together with TSMC is “almost finished” and they are already in the early stages of AI6. Meanwhile, he hopes that there will be a new version every nine months, with the AI7 and subsequent ones in the company’s plans for 2027. And a big question is who will make these chips. We can immediately think of TSMC, a leading company in these fields that even is expanding in the United States and that already has clients like herself NVIDIA for its new AI training chips. But no: it will be Samsung. At least, of course, for an AI6 with which Tesla signed a $16.5 billion deal that was seen as a victory for the South Korean giant’s function. We will see how the plans evolve, since if something appears that they consider better, they have shown us that their hand does not tremble when it comes to swerving, but This strategy on less specialized chips is interesting taking into account the needs in autonomous driving, AI training and robotics that the company faces.

Exactly 100 years ago we began to understand how the world works. Quantum physics has radically changed our lives

Well, not exactly 100 years ago. 100 years ago and one day. On July 9, 1925, German physicist Werner Heisenberg sent a letter to his friend Wolfgang Pauli, who at that time was already a very renowned theoretical physicist of Austrian origin. Heisenberg had been engaged for several months in the development of an idea that was permanently breaking with The classical conception of the atom as a tiny planetary system in which electrons orbit around a nucleus constituted by protons and neutrons. That letter contained several reflections that Pauli knew how to appreciate. In fact, shortly after receiving it Max Born, Pascual Jordan and Wolfgang Pauli himself took the work of Werner Heisenberg as a starting point to prepare for the first time in history a mature formulation of Quantum theory. The content of that letter supports nothing more and nothing less the most ambitious and precise framework in the history of science: Standard model of particle physics. Without him many of the technologies we enjoy today would not be possible. Quantum mechanics is very present in our day to day “Dear Pauli, if he believes that I read his letter laughing mockingly, he is deeply mistaken. Actually, the opposite happens; from Helgoland (it is a small German island located in the North Sea) my views on the mechanics have become more radical every day that passes, and I am firmly convinced that Bohr’s theory of the hydrogen atom in its current form Zeeman “. The article ‘Umdeutung’ (‘Reinterpretation’) of Heisenberg is considered the birth certificate of modern quantum theory The first lines of Heisenberg’s letter They clearly reflect the trust and respect he professed towards Pauli. And also how much the revolutionary ideas I had in mind were disturbed. In fact, a few lines later confess to having many doubts about the way he could carry out The rigorous formulation of those thoughts: “As for my own opinion about this scribble, with which I am not at all satisfied: I am firmly convinced of the value of the negative and critical part, but I consider that the positive part is rather poor. Even so, perhaps those most capable that I can get something sensible to it.” The scribble that Heisenberg speaks was actually the draft of his famous article ‘Umdeutung’ (‘Reinterpretation’), which shortly after was published. Many physicists consider that text the birth certificate of Modern Quantum Theory. Neither more nor less. Anyway, there is no doubt: during the next 100 years Heisenberg’s ideas and other physicists who also made decisive contributions to quantum theory, such as Wolfgang Pauli, Erwin Schrödinger, Max Born, Paul Am Douc, Niels Bohr or Albert Einstein, triggered the birth of many of the technologies we currently use. Integrated circuits containing all our electronic devices, Solar panelsmagnetic resonance machines, The lasers or the atomic watches that allow the human being to measure time with an unprecedented precision would not be possible without the knowledge that modern quantum theory has given us. And, of course, without this model we would not have Quantum computers. Objectively, and it is not at all an exaggeration, Quantum physics is present in much of modern technology. And all probability will continue to be in many of the innovations that will arrive in the future. That is not the slightest doubt. After all, it is the best tool we have to understand how the world works.

There is a key to radically improve mobile photography. The problem is that only Xiaomi is applying it

The highest range mobiles They make good photographsThat is undeniable. As it is also undeniable that the defendant is increasingly aggressive and, with him, ends dying naturalness in photographs. But not everything is software, our camera sensor largely determines how aggressive they need to be (or not) those computational decisions of the phone. That is why an inch sensors have been demonstrating a simply brutal muscle. Xiaomi has cited us on March 2 to know his Xiaomi 15 Ultrayour photographic flagship. The company itself has given some brushstrokes about how the camera of this beast will be, revealing that it will repeat with the sensor configuration of an inch. This movement, although not new, is one of Xiaomi’s differential factors in the market. Although the camera sensors of an inch They have been with us for more than four yearsThey have not managed to be a standard in the highest range. Or, at least, in which it is sold in Europe, since some of the best Chinese phones with gigantic sensors are not sold in our territory. Samsung Galaxy S25 Ultra: 1/1.3 “. iPhone 16 Pro Max: 1/1.28 “ I live x200 pro: 1/1.28 “ Realme GT6: 1/1.4 “ Sony Xperia 1 VI: 1/1.7 “ Honor Magic7 Pro: 1/1.3 “ OPPO FIND X7 PRO: 1/1.4 “ Xiaomi 14 Ultra: 1 “ It’s curious. We have been talking about an inch sensors for years, but there is only a high range among the great manufacturers that bets on this type of sensor. An inch sensor on a mobile phone offers significant advantages in the quality of the photos and videos, mainly due to its larger size compared to the smallest sensors that are usually integrated into smartphones. One of its keys is the best light collection, since A larger sensor has a larger surface to capture light, which translates into images with somewhat less noise in low lighting conditions. This is key, at a time when manufacturers are obsessed with their noise reduction algorithms. They are also sensors with greater depth of field (an older and better natural bokeh, so that we understand each other), and that at the technical level, allow to obtain more detail. They are little if they are not worked but, well used, these sensors are a before and after (especially in RAW shots). The problem? Introducing an inch sensors is more expensive, it requires more space in the telephone body, and complex optical development to take advantage of its potential. An investment of resources to which all manufacturers are not willing. Image | Xiaomi In Xataka | Mobile cameras will not improve as much as the sensor size increases. There is a very clear responsible
