Everyone is harmed

by

From the electric blackout of April 28, the authorities have activated several analysis committees to clarify The exact causes of the incident. Although there is still no defined cause, specialized working groups have already been created and open commissions with Portugal and France to coordinate answers to this phenomenon that crossed borders. In spite of all this deployment, only preliminary hypotheses are handled And new clues that, far from simplifying the stage, make it more complex. A new track. The Ministry for Ecological Transition (MITECO) convened a third meeting that in the investigation phase was discovered a “third event” that may be related to the trigger of the crisis, According to EuropePress. This disturbance occurred exactly 19 seconds before the main incident registered at 12:33 p.m. on Monday, April 28. Technical chain The information available so far points to a technical and operational network much more than what was thought at first, such as He has reported EuropePress. It would not be simply a punctual error, but of a conjunction of events, possibly interdependent, which affected the stability of the system. In fact, this week, the cybersecurity group teams are visiting operation centers, such as Red Electrica, to collect key information In situ. They already warned. There is a question that does not stop around the debates about whether the electrical system is ready to adapt to a new model based on renewable energy. According to the economistRed Eléctrica had requested from the Government a period of five years to adapt its security measures to the new reality of the electrical system, more decentralized and with a growing weight of renewable energies. This does not imply a direct responsibility in what happened, but it does indicate an ongoing transition that requires resources, time and planning. The management of a network with more renewable weight involves new technical challenges, which the system is still learning to handle. Under the same focus. In the midst of this analysis process, the Executive has decided has detailed The newspaper. The decision has generated tensions, since some voices consider that precipitated or guilty decisions are being made without conclusive evidence. For its part, the Government has argued that exclusion responds to the objective of guaranteeing an independent analysis, although this decision has fueled criticism. The truth is that the public image of the blackout has harmed all the actors involved: operators, electric and the government itself. The lack of a clear and univocal cause makes this case an uncomfortable puzzle for all parties. In this sense, as one of those responsible for the analysis has signed internally, “the photo of the blackout harms everyone.” It will take time to resolve. Similar cases in other countries show that clarifying these types of incidents have been. In the United States, for example, the mass blackout of Texas in 2021 It took several months In being analyzed in depth, with technical reports, legislative appearances and cross data on weather, generation and demand. In Italy, the great blackout of 2003 also He needed weeks of research to determine the exact sequence of failures. It is a complex type of analysis, where each technical data has operational, political and regulatory implications. Follow the investigation. As the meetings progress – the planned with Ree today – the technical teams are expected to establish a more precise sequence than what happened. At the moment, the only clear thing is that we are facing an unpublished situation, unprecedented recently in the Iberian electrical system. Instead of looking for a single responsible, the focus must now be to thoroughly understand the technical, structural and operational causes of the blackout. Only in this way can something similar happen again. Image | Seoane Prado Xataka | The blackout left all Spain without capacity to communicate. The problem is that it also isolated the government

BBVA wants to buy Sabadell for less than what is worth

by

The CNMC He has given the green light to BBVA OPA on Banco Sabadell imposing commitments for three years, but the greatest obstacle is not regulatory but financial. The operation presents A mathematical paradox: BBVA offers much less than Sabadell’s actions are worth. The approval of the competition agency, far from clearing the way, has put on the table the contradictions of an operation that has been taking over more than a year and still having serious obstacles both financial and politicians. In figures. The Basque Bank proposes An exchange of one action for every 4.83 shares of Sabadellwhat each Catalan bank title values ​​in 2.39 euros, compared to 2.56 euros to which he quotes. This 7% negative differential is the main anomaly of this operation. There are hardly reasons for Sabadell shareholders to accept this proposal. Main loser? Sabadell small shareholders, which They represent almost 50% of the capitalThey have no incentives to accept an offer that would make them lose money regarding selling their shares directly in the market. This Atomized structure of the shareholders It is precisely one of the great challenges ahead of BBVA, which would need to convince thousands of retail investors to accept an operation that, at least in strictly economic terms, harms them. Between the lines. The 7% discount indicates that the market assigns a few probabilities of success to the operation. If investors believed that the OPA will prosper, the price of Sabadell would be converging towards BBVA’s offer, not moving away from it. Although BBVA tries to convey an optimistic narrative about the chances of success of its offer, that 7% gap transmits otherwise. Turning point. BBVA has repeated that its offer will not improve because doing it would harm its own shareholders. Its calculations indicate that it has up to 2.3 billion to improve the operation, but this would erode the profitability for its investors. The bank is at a crossroads: Or maintain its current offer assuming that you have little chances of prospering … … or the improvement at the cost of harming their own shareholders, which contradicts their duty as a quoted company. The backdrop. The government adds uncertainty to the process with The announcement of an unprecedented public consultation prior to its final decision. Pedro Sánchez has stressed that he will support the operation “as long as it benefits the common interest.” This consultation, unprecedented in operations of this caliberunderlines political reluctance towards a bank concentration that would further reduce competition in the sector and could have consequences in access to credit for individuals and SMEs. And now what. CNMV must now approve the OPA brochureprobably in early July, opening a 30 -day acceptance period that will partially coincide with August, month of low stock activity. This circumstance could lengthen the process until September, far beyond the original calendar that managed the BBVA. The calendar thus plays against an operation that accumulates both delays and uncertainty. Financial logic suggests that the operation is dedicated to failure if BBVA does not improve its offer, but doing it would harm its own shareholders. It is a dead end alley for one of the greatest business operations in Spanish banking.

Now the era of Chinese propaganda has begun

by

The Commercial War It is fought on the parquet of the bags, in the Cultivation fields, Factories and portsbut also in the networks. In fact, one of the key battles in the struggle between Washington and Beijing is played: that of the story. We saw it not long ago with the Viral videos Created with which they make fun of Donald Trump’s effort to reindustrialize the United States via tariffs. Now that struggle to guide discourse in networks seems to have gone further, with A Video Cascade in Tiktok that affect China’s benefits against the supposed decline of the USA. His propaganda approach is clear, just like his leitmotiv: Show China as a kind of Tecnoutopía futuristic. The (another) Great Pulse. He Tariff pulse Between Washington and Beijing, which has raised above 100% The rates that each country applies to the exports of the other, is already being felt in the fields, factories and ports. In those of the US, in those of China and even in those of third nations that have come out in some way favored, Like Brazil. Beyond government offices or large corporations, there is another ‘battlefield’ in which the struggle between China and the US seems to have aggravated: the networks. 11 tricks to dominate Tik tok @schbachlq Urban Greens #Foryupage #USA🇺🇸 #China #Americandream #chinatravel #fyp ♬ Original Sound – Schbachlq “Maga”, in the spotlight. A few weeks ago, in full escalation of the commercial war between the two nations, it went viral in Tiktok A series of videos elaborated with the in which Americans were overweight working in Nike, Tesla, Apple or Nvidia assembly chains. Everything between posters of “Make America Grate Again” or “Made in USA”, fried potatoes, soft drinks and an environment that even invited to think about clandestine factories. The message was powerful because one of the arguments wielded by Trump to justify the tariff war just that: Revitalize the US manufacturing industry. “Confrontative and mocking”. Bloomberg a few weeks ago It echoed From another campaign displayed in Tiktok, a platform in the hands of China bytedance and whose property (and the influence that the Xi Jinping government can exert on it) has generated An intense debate legal and political in the US. So much, in fact that the Supreme Court He came to veto her In the country if Bytedance did not sell it, a measure that Trump’s return to the White House He left in suspense. According to Bloombergnow Tiktok has served Influencers Chinese to encourage Americans to buy directly in the Asian giant with titles such as “China exposes the truth.” “These publications are much more confrontative and mocking with the US, instead of showing it as a threat,” Explain to the agency Tom Harper, professor at the University of East London, before remembering the videos generated with the Americans working on Nike, Tesla or Apple assembly chains. Apart from his ironic tone, the virality of these pieces demonstrates something else, such as Remember Bloomberg: The capacity of Chinese content creators to reach the US society through the Tiktok algorithm and other Asian networks, such as Xiaohongshu either Rednote. @zhiwen.Shen Which World Do you want to live in? #China #USA #chinese #fyp #Worldtody#chinalife#COTAST ♬ 困住你的不是别人 (李羲承进行曲) – Dj 阿智 @mindblowndai1y Use vs China Cars 🚘 #chinavsusa #fyp #tiktok #China #USA #Car #Cars ♬ Original Sound – SocialCreditgod China, year 3,000.

For the first time an unmanned boat has knocked down Russian combat planes

by

At the beginning of February there was An unusual factnot for war in Ukraine, but for any other armed conflict known in history. If the battle of drones was redefining the modern combat, the conflict gave green light to something new: dwarfs of drones “mother” in turn launching other drones to attack in turn to rival drones. The latest: boats with missiles demolishing Russian fighters, and without No one behind the wheel of vessels. Lethal innovation in the Black Sea. In an unprecedented event, the Intelligence Directorate of the Ministry of Defense of Ukraine (GUR) managed to tear down two Russian fighters Su-30 Flanker using air-air missiles AIM-9 Sidewinder. The surprising thing is from where they launched: Magura-7 naval dronesas Lieutenant General Kyrylo Budanov declared exclusively To The War Zone. This unpublished action, which occurred in the Black Sea, represents not only the first time that combat planes are dejected From unmanned vesselsbut also the First lethal use AIM-9 missile confirmed from this type of platform, which underlines the degree of sophistication and innovation achieved by Ukrainian forces in the Maritime Theater of Operations. Details of an unusual attack. Apparently, the operation used three magura-7 dronesan anti -aircraft variant of the model Magura-5of which two shot at the Russian fighters. According to Budanovthe first SU-30 was reached and its crew survived after being rescued by a civil ship, while it is presumed that the pilots of the second apparatus perished in the attack. So far, there are only images of the first demolition disseminated in networks social. We remember that the use of AIM-9M missiles, a more advanced variant than R-73 Sovietdemonstrates Ukraine’s ability to integrate Western armament into unconventional platforms. Unlike R-73, the AIM-9M lacks the High-Off-Boresight capacity (Hobs), forcing the missile to be oriented directly towards the objective to acquire white. However, their best background discrimination, infrared countermeasures and smokeless propulsion offer significant tactical advantages, especially in an environment where drones must operate with discretion. Precedents and evolution of doctrine. The incident is put along with the occurred in DecemberWhen Ukraine reported the successful use of an R-73 triggered from a USV to deed a Mi-8 helicopter Russian. Since January, according to Budanov, Ukrainian engineers began to install AIM-9 in these unmanned vehicles, consolidating an evolution that Combine elements of air defense, electronic war and asymmetric naval combat. Although the exact launch configurations have not been disclosed by Ukrainian intelligence, everything indicates that Magura-7 represents A hybrid node high mobility capable of operating in areas where air control is highly disputed. Russian reactions and consequences. Moscow’s response has not been waiting. Through various Channels in Telegrammilitary analysts and commentators have recognized the effectiveness of the attack and indicated the growing deficiencies in the defensive capacity of the Black Sea. The War Cárs correspondent Kitten channel He expressed his alarm For three factors: the loss of the maritime initiative, the degradation of the Black Sea fleet after the destruction of the Moskva cruise, and the apparent Ukrainian domain in the use of unmanned vessels capable of projecting power even on the Russian coastal airspace. The analyst Vladislav Shurygin regretted That the attack followed the same lure and ambush pattern already observed in other Ukrainian operations, criticizing that Russian doctrine seems unable to adapt to these tactics. Meanwhile, the Two Majors channel strongly questioned the Lack of effective means To neutralize the USV, proposing the use of FPV drones or the combination of UAV of Zala recognition With ammunition Lancet Merodetersas already happens on the mainland. Technological implications. No doubt, the use of air-air missiles on non-manned naval platforms redefines the rules of combat in the black Sea. Historically, The Sidewinder They have adapted to naval defense systems Like the Chaparralbut its surface Kamikaze drones grants Ukraine a mobile, hidden and scalable tactical capacity, capable of deterring Russian aviation without compromising high -value human or material resources. In addition, it reflects a constant evolution in the use of donated western systems, many of which, such as AIM-9M, were originally thought For manned fighters and now they are reconfigured on innovative platforms that They multiply its impact strategic. Although the United States and its allies have not publicly detailed how many missiles of this type have delivered to Ukraine, it seems clear that its use is far from limiting themselves to conventional air combat and is expanding the lethality of the Ukrainian autonomous systems. A turning point. In short, the demolition of the two SU-30 fighters by Ukrainian naval drones Mark a symbolic and operational turning point. As the war in Ukraine enters its fourth year, the control of the maritime space becomes as crucial as the land domain, and kyiv once again demonstrates its ability to convert material limitations in asymmetric advantages. We have come counting as that grew Industry without a paragon Around drones. By integrating Western technologies with its own doctrine, Ukraine is creating a new class of hybrid threats difficult to detect, anticipate or counteract. The incident not only represents a punctual victory in tactical terms, but also a meridianly clear message: Russian naval power is no longer unquestionable not even in front of small unmanned boats that are capable of driving fighters tens of kilometers from the coast.

The commercial war between China and the US has had an unexpected injury: Starbucks

by

Just a year ago we talked to Xataka of the delicate moment through Starbucks. A year later, the world’s largest coffee chain deepens the crisis of its business model, now trapped between those structural problems, which came from afar, and a new problem: Trump’s tariffs. The current situation. Starbucks accumulates five consecutive quarters of falls In sales in the United States. Only in the last quarter, transactions fell 4%, although average customer expenditure increased by 3%. It does not matter: that increase is insufficient to compensate for the loss of traffic in coffee shops if customers look for cheaper alternatives like Dunkin ‘or McDonald’s. Why is it important. The company depends on coffee imported from more than 30 countries, and with The new 10% tariffshis commitment not to raise prices in 2025 further complicates the recovery of his margins, which were already down. The context. What for years was an unstoppable growth story, tripling its premises from 2012 to exceed 40,000 in 2024, it has now become a struggle to maintain its profitability. The United States, its main market, is saturated. And China, its great growth commitment, has its own problems. The US market shows clear signs of maturity with a growth of premises that has slowed down. In China, although it has almost doubled its stores in five years, income has stagnated, with flat interannual sales (0% last quarter). The latter has a lot to do with Nationalist consumption That put local alternatives before. The threat. Beyond tariffs, Starbucks has other open fronts around its business model. Between the lines. The new CEO Brian Niccol, signing of Chipotle with music from Fanfarrias, has launched the Plan “Back to Starbucks“To recover the essence that made the company great. However, he recently recognized that “our results of the second quarter are disappointing,” although he also said he “confidence that our plan is the right strategy to turn the business.” The unexpected turn. Despite all these problems, Niccol maintains its commitment to freeze prices in 2025, a brave decision (and we will see if reckless) when their competitors will surely increase them due to the impact of tariffs. It is true that this strategy could give it competitive advantage if it manages to control its margins on other ways, but it is also that these margins are increasingly constrained. In figures. The financial situation explains the deterioration of the business: The actions almost 30% have fallen From the announcement of tariffs. Its adjusted operational margin of the last quarter was 8.2%, quite below the expected 9.5%. The benefits collapsed more than 50% compared to the previous year, to 384 million dollars. The company accumulates 23,000 million net debt, with a indebtedness ratio superior to triple. The latest. Starbucks has already implemented several measures to contain costs: Elimination of extra charges for alternative milks. Reduction of customization options. Product discontinuation. Free recharges offer for those who consume in their establishments. The question now is whether these measures will be enough in the face of an increasingly hostile economic environment, where consumption habits are changing and the experience that previously defined Starbucks no longer seems sufficient to justify their prices.

launch your first laptop with Linux

by

The list of entities of the US Department of Commerce is not a pleasant place to be. Huawei has already lost its use licenses for Google services, and the same has happened with its Microsoft agreements to use Windows in the company’s laptops. Huawei can continue to sell Windows laptops that are already in the market, but the production of new devices with this operating system depends on licenses, now subject to restrictions. The scope of them is global and will affect the availability of Huawei products with Windows in Europe. But the Chinese company has a plan. The license agreement. Huawei now has with Microsoft the same situation as with Google. You cannot use your licenses in any of your new manufacturing products. As you had to say goodbye to Google on its Android mobiles, the company can no longer manufacture Windows computers. Huawei’s response. Already in September 2024, before the imminent expiration of the license agreement, Richard Yu himself responded in an interview He advanced that the current PCs of Huawei would be the last with Windows, and that those of the next generation would come hand in hand with their own operating system, Harmonyos. It is an answer that does not throw too many doubts in China, where Harmonyos Next is the clear commitment of the future. But in Europe the consumer profile is different, and the state of Harmonyos is very incipient. Harmonyos Next. Huawei is clear that the future of its software is to create a complete ecosystem in which PC, smartphone, smart watches and even electric vehicle are connected. For this it is developing Harmonyos Nexta system without a trace of Android or Linux core, 100% own with a native kernel. This is the beginning of most ambitious software project never executed by the company, a proposal that We will begin to see this year on PCs sold in China. Linux always remains. Outside China, Harmonyos does not make too much sense, since the appus ecosystem is yet to be built. Just a few hours ago, the company announced the Huawei Mate X Pro in its versions 14 and 16 … executing Linux and running with an Intel Core Ultra 7. It is exactly the same device as the company sold with Windows, but with a Linux environment and a change price of 1,352 euros (10,399 yuan). The laptop It can be bought in Vmall (as long as you live in China), and supposes a whole before and after for the company. The doubt of Europe. Linux has a quota in Europe that Round 3.4%a fact that makes it practically impossible to get a device with this operating system to end up being a sales success. Losing Google’s services cost Huawei to lose its position in the smartphones market, and without a quick software response, the fate of its laptops seems similar.

A stabilization of poor electricity

by

In 2024 23.2% of Electricity of the Spanish Energy Mix It had a wind origin; 20%, nuclear; 17%, photovoltaic solar; 13.6%, combined cycle; 13.3%, hydraulic; and the rest proceeded from the burning of coal or other renewable sources. The accounts are very simple: during the year we have left behind More than 50% of electricity production It had a renewable origin. And presumably In 2025 the total energy balance It will not be very different. The Government of Spain has created an investigation commission that seeks to identify the causes of the total blackout that we suffer throughout the country on April 28. However, during the last days in the media and social networks Some experts have indicated the need for a country with such a high production of Energy of renewable origin have an effective stabilization system. The intermittent nature of renewable sources justifies this thesis. The Spanish energy mix needs a stabilization system of the robust network The figures that we have reviewed a few lines above Nuclear energy for the moment too holds an important contributionalthough in this article we are interested in repairing a very relevant difference between both forms of electricity generation: its continuous or intermittent character. Nuclear reactors produce energy in an essentially constant way as long as it is not necessary to undertake Fuel recharge or carry out installation maintenance operations. However, wind and photovoltaic energies, of course, depend on the availability of wind and solar radiation. This obvious behavior explains Why are intermittent energy sources. However, there is something that is not obvious: the electricity grid must maintain a permanent balance between generation capacity and consumption. The electricity grid must maintain a permanent balance between generation capacity and consumption This simply means that wind farms, nuclear plants, photovoltaic solar facilities, combined cycle plants and hydraulic plants that are connected to the Spanish electricity grid should be able to deliver at all times the electricity that is being sued. Otherwise there would be an imbalance between the generation capacity and the consumption that could trigger very important problems in the electricity supply. I could even justify a total blackout like the one we experienced just a week ago. The two parameters that we are interested in knowing to understand why this imbalance is problematic are the frequency and voltage or voltage. The Spanish electricity grid, like those of our European neighbors, works with alternating current at 50 Hz or cycles per second. When we investigate the panorama, the panorama is complicated a bit, but not too much. Electricity is distributed throughout the Spanish territory through a high voltage network that has 44,000 km of 220 kV and 400 kV lines. Once electricity is close to the points where intermediate substations will be consumed are responsible for reducing the voltage to 132 kV. In medium and low voltage networks, electricity has a voltage of 15 to 30 kV, and, finally, local transformers reduce it to 230 volts for domestic use in our homes and shops, OA 400 volts for industry and large consumption centers. The problem appears when for the reason that is the electrical infrastructure undergoes a significant deviation of frequency or voltage. Synthetic inertia systems that mimic the behavior of rotating masses can also help renewable to correct the imbalances between demand and generation quickly An important imbalance between the planned generation for renewables from meteorological models and real generation can cause it to occur an excess energy that is not assumed by consumption. Renewable sources do not have a mechanical inertia system that allows them to quickly correct that difference, so it is possible that a deviation of the frequency and tension of the ability to compromise infrastructure performance is tried. The nuclear and thermal plants, however, have a rotating mass that acquires the inertia necessary to cushion the sudden changes of their generation capacity. Fortunately, these imbalances can be avoided, but to do so it is essential to have energy storage systems or reversible pumping to deliver or absorb power when necessary. Synthetic inertia systems that mimic the behavior of rotating masses can also help renewables correct the imbalances between demand and generation quickly. Such a heterogeneous energy mix As Spanish can work properly, but it is essential that you have a stabilization of the robust and efficient electricity network. Otherwise the quality and reliability of the electricity supply will be compromised.

The extreme temperature in which the laws of physics we know stop operating

by

The absolute zero marks the minimum temperature at which something can be found and corresponds to -273.15º Celsius, or 0 Kelvin. Since heat is nothing other than movement, this temperature marks the total stillness, but what happens at the opposite end? Planck temperature. Although we are less familiar with the other extreme, Planck’s temperature, or the “absolute heat”, Another concept managed by contemporary physics. Here we might make emphasis on” contemporary physics “since, at this temperature, what we know of physics stops operating, which leaves us in an unknown terrain. How much heat are we talking about? Well around 142 quintillones Kelvin (K). Or what is the same, 1.42 · 10^32 degrees Celsius: the 273 degrees of difference between both scales are inconsequential on this scale. As a comparison, we can point out that the estimated temperature of the core of our sun is about 15 million Kelvinalthough the remnant nuclei of some supernovas can reach the billion degrees. Here on Earth, science has achieved even higher temperatures: More than 5 billion Kelvin in an experiment conducted in 2012 in the Great Hadron Colliding (LHC) of CERN. Defining the maximum. We indicated before the absolute zero in temperature was marked by the lack of movement, the absence of thermal energy. The temperature is an energy transfer measure, if something has no energy, It cannot transmit it. However, to find absolute heat we must go beyond thermodynamics and incorporate another area, that of quantum physics. To understand this limit, we must know that heat is associated with emissions in the electromagnetic spectrum. At more heat, more energy, shorter will be the frequency in this spectrum. Well, this spectrum is not infinite since the known universe has its own minimum distance, Planck’s distance. This minimum length Mark too The shortest wavelength and the maximum energy that we can introduce into a photon. It is therefore impossible to transfer more thermal energy. A rather theoretical idea. Planck’s temperature remains, as we pointed out before, far from both what we can see in the universe and what we are able to recreate in a laboratory. There was a time when it may not be so, since in the first moments after the Big BangThe universe would have reached this type of temperatures. But precisely the Big Bang It is one of those contexts in which the laws of physics as we understand them are not applicable. Beyond contemporary physics. The Big Bang is a clear example that there is physics that still escapes us, as are black holes. In both cases these are contexts so extreme that the description of what happens in them through the laws of physics we handle makes it impossible. However, we continue in the search for knowledge about these extremes and the laws that could operate on them. Probably, the long -awaited “theory” of all that unifies what we know about relativistic gravity with quantum physics can give us important clues about this border of heat and, above all, what may be beyond this.
