The United States has tired of the monopolies of great technological ones. And wants to start “chop them” with goal

April 15, 2025 by usatoday24

The United States turned a blind eye with its great technological for years. He did not pay too much attention to whether they abused their privilege position or had monopolistic and anti -competitive behaviors, Something that was pursued by the European Union. That has changed, and we are seeing how one after another the Big Tech are being scrutinized in the American judicial courts. Not only that: the threat to those giants is to finish chopped. FTC against goal. The Federal Trade Commission (FTC) trial of the United States began yesterday, and for two months it will try to decide whether the company created by Mark Zuckerberg is a monopoly in the “personal social media services market” market. The consequences can be huge for the goal, which could be forced to divide into several companies. Zuckerberg on the stage. As they point out In The New York TimesMark Zuckerberg came yesterday as a witness to defend “his social media empire.” The FTC lawyers showed several emails in which they raised their argument: what a target “illegally cemented a social networks monopoly by acquiring Instagram and goal when they were small startups.” Zuckerberg made it clear in this Email of April 2012. Better buy than to compete. Source: Big Tech on Trial. If it is a threat to your domain, buy it. The Tactics of the FTC lawyers is to demonstrate that goal used their privilege position to buy companies that could represent a threat in the future. It is the strategy that Some call (rightly) “Better buy than to compete.” To those accusations Zuckerberg replied saying that they ended up investing a lot of money in them after buying them, but doing so they managed not only to reinforce their dominant position, but to eliminate those threats that Instagram or WhatsApp raised. The FTC proposes to chop target. If the government wins the trial, they point out on the Times, the FTC probably asks for the goal to divide into several parts. Thus, Instagram and WhatsApp could be independent companies that would compete with each other with Facebook, or at least that would be the intention of the government. Too much power. Thus, the government must demonstrate that goal would not have had the same success without those acquisitions. It is something really complicated, but this is part of the effort of recent years to try to mitigate the enormous power that technological giants have. These privilege positions allow these companies to clearly influence the exchange of ideas, entertainment and of course political debate. A peculiar judge. The case is chaired by Judge James Boasberg, 62, who already faced a Trump decision in a previous case but that above all attracts attention by a choice: he affirms that he has never used the goal applications, although he is familiar with Facebook Live, which has been used in some criminal cases. Google is in the same. Last summer, federal judge Amit Mehta pronounced a few words that were not evident were less important: “Google is a monopoly“. And threat of “chopstick”Fines do not seem to function as punishment for these types of companies, and for years another option than politicians has been considered Like Senator Warren They defend to act against the Big Tech: chop them. In the case of Google, the sentence could force Alphabet, the matrix, to get rid of Chrome and even Android. Apple, another of the objectives. In March 2024 the Department of Defense (DOJ) accused Apple of being a monopoly and to close the iPhone and iOS to the competitors. The United States followed the steps of Europe, although in this case, which has not yet concluded, a company’s split was not raised. Amazon is a monopoly. Years before the US Congress has already concluded that Amazon was a monopoly in the field of electronic commerce. The long investigation ended with A document of almost 500 pages, but had no specific consequences beyond an attempt to reform legislation in this regard. The US follows the EU wake. For years the European Union has been the nemesis of the large technological companies of the US, which it has stopped with fines and sentences that punished anti -competitive practices. We saw it a few months ago when Meta received A fine of almost 800 million euros for one of this type of cases. The new roof of the Big Tech. Microsoft was a clear objective of the European Commission at the beginning of the century, and since then the antitrust cases They have happened constantly, as companies such as Google either Apple. In the US, such issues seemed to be in the background, but from a time to this part of the US justice It has become very serious With these companies, as we have been able to check with Amazon, Apple, Google and now Meta.

You will start adjusting your template, according to Business Insider

April 11, 2025 by usatoday24

Although the figures registered in 2022, 2023 or 2024, years in which each round of layoffs are not being reached segated thousands of jobs. According to The portal Layoff.fyi,The great technology have fired 23,505 employees in what we have been. The most recurring reason: the Restructuring of the departments To gain agility. According to Published information by Business InsiderMicrosoft would be considering a New round of layoffs They aim to reduce the number of intermediate and management positions, as well as Posts “No coding“. That is, positions not directly involved with software development. Programmers are not the objective Anonymous sources close to Microsoft assured the American media that the technology prepares Another round of layoffs that could be executed next May, but do not provide a specific figure of the number of employees that will be affected by the measure. The spokesmen of the company consulted by the medium have declined to comment. According to what is published, the adjustments that are coming will be focused on the intermediate controls and team managers, as well as in DEVELOPED DEVELOPMENT DEPARTMENTS Software direct. This includes commercial, human resources and managers departments. Microsoft already carried out layoffs at the beginning of the year. But unlike that, the new round would not have the objective Like Google and Amazon. Less bureaucracy and more agile teams Charlie Bell, co -founder of Amazon Web Service and current Chief of Security of Microsoft, could have brought from Amazon this ratios system. Its objective is to redirect the maximum of Personnel resources to the development area To step on the accelerator in matters such as AI or the creation of new software solutions to put back to Microsoft in the AI race. Applying this strategy, Microsoft would be looking for an infrastructure with development equipment with less bureaucratic obstacles in the command chain and more dynamic reducing the number of department managers. Hence, the main objective is not to reduce the template in general, but in specific positions. According to sources of Business Insiderthe department managed by Charlie Bell has a ratio of 5.5 programmers for each manager, when the objective is to achieve a proportion of 10 to 1. This strategy is slightly different from that adopted by technological ones as a goal, which in its last round of layoffs hardened the performance scales, which served as an excuse for dismiss 5% of your workforceincluding in that list many software engineers that had to date had good grades. However, although programmers are not the objective priority in this personnel cut, Microsoft could take the opportunity to say goodbye to some employees (including programmers) that have a “impact 80” or lower performance rating for two consecutive years. The company establishes a 200 scale, in which 100 would be an average yield. Therefore, a programmer with a qualification of 80 would be yielding below the measure and could be one of the names that go in The next list of layoffs, Although your profile is development.

Lack of motivation is a problem for productivity. The trick to avoid it is simple according to science: start

April 5, 2025 by usatoday24

Complete your goals and be more efficient with your time, both work and personal, may seem a complicated challenge, especially when procrastination is An incombustible threat that gets in your path. Use small tricks for Encourage your motivation which serves as gasoline for Maintain productivity You can make a big difference in how you face your daily tasks. These are four strategies that can help you maintain your motivation and prevent distractions from moving away from your goals. Completing tasks is already a motivation for your brain According to Manu KapurProfessor of Learning Sciences and Higher Education at the ETH of Zurich and author of ‘PRODUCTIVE FAILURE‘, “We like to close paths. We like to finish what we start. In fact, we have a strong affective impact by completing what we have worked in “, He countedProfessor a Fastcompany. This is corroborated by Zeigarnik Bluma Studies In 1927, which gave rise to the call Zeigarnik effect A condition of the brain that prioritizes the retention of that information you need to complete a certain task. On the other hand, Maria Ovsiankina complemented Zeigarnik’s investigations in 1928 demonstratingThe natural tendency of the brain to finish those tasks that you have already started, Even when it is not mandatory to do so. He does it for an unstoppable need to close a door that was kept open. Therefore, one of the Keys to maintain motivation To complete the tasks it is simply starting them. Take the first step. This is what Mel Robbins, speaker, creator of the podcast The Mel Robbins Podcast and author of the book ‘THE POWER OF THE 5 SECONDS: Be brave on a day to day and transform your life‘called in Your Ted talk“Activation energy”. According to Robbins, the greatest ally for procrastination is immobility. Once You dedicate two minutes to a taskthe brain itself finds tools to stay in it until you finish it. 1- Divide tasks One of the reasons why procrastine and the motivation to face tasks is lost is the overwhelming feeling that The task is too big. The solution could not be simpler: divide it into smaller and more manageable tasks. This approach uses what Psychology experts Teresa M. Amabile and Steve J. Kramer have called “effect of progress.” In their research they analyzed thousands of employee labor newspapers and found that progress, even incremental, in their tasks is the most important factor to maintain labor motivation. Every little achievement achieved release dopamine in the brainwhich activates a sense of reward, thus increasing the levels of motivation. Therefore, these completed tasks have a positive effect on emotional state and motivation, which increases productivity and commitment. Amabile and Kramer’s studies are the key that demonstrates the importance of dividing large goals into small steps to promote a constant sensation of progress. 2- Look back helps continue If the task is longer than expected and you see that your motivation begins to falter, Kapur recommends Change the work perspective That you have to do, on the path you have already traveled. “If you are very far from your goal of swimming 20 lengths, you can say: ‘I came to swim a long one. I have already made five more.’ This system is known as the gradient effect of the objective, and is a concept in psychology and motivation that describes how people tend to increase their effort and motivation as they come to achieve a goal. This phenomenon was initially studied by the Psychologist Clark L. Hull In 1932 and is widely applied to areas such as human behavior, marketing, productivity and personal goals. A 2006 study Made by Kivetz, Urmininsky, and Zheng for the field of neuromarketing, revealed how consumers accelerated their purchases to complete rewards programs. In addition, research in the workplace have shown that, when employees come to complete a project, Its approach and productivity tends to increase. Especially when you are at the beginning of the task, you can fall into the trap of looking towards an objective that obviously still remains far. That perspective acts as a brake for the first advice we gave you, so, to mitigate it, it is much more motivating to take a look at all the work you have already done and put it in value, in front of which it still remains to be done. 3- The fallacy of the sunk cost Have you ever continued seeing a mediocre series or reading a book just because you have already started? Is what is considered Sunk cost fallacywidely cognitive bias studied in psychology and behavioral economy. It refers to the human tendency to persist in a decision, activity or investment simply because we have already dedicated time, money or effort, even when your continuation It is not rational and leads to losses additional Now imagine that, after many years of study, dedication and efforts, you are in a job that is not what you expected and It bores you tremendously. The fallacy of the sunk cost can make you believe that, since you have dedicated so much effort and dedication, you will not change work area to something that, perhaps, motivates you much more. As his own name says, it is a fallacy. The “sunken cost” that represents the training or work done to reach your position is not something that is going to be lost, but adds points to your personal account as an experience, skills and knowledge that can be used in any other sector. “Each recognition is valued and the effort is celebrated. The student realizes that it does not start from scratch, he has relevant previous knowledge, but that they need to be activated, extracted and registered in his mental progress,” says Professor Kapur. 4- The final sprint Have you wondered how a marathon corridor, after having given everything for more than 42 km gets enough energy to tighten the rhythm in the last meters before the goal? It is the power of motivation that drives the brain to end … Read more

How can you activate it and start exploring its functions

April 1, 2025 by usatoday24

If you live in Spain and you have a compatible device, from today you can start using Apple Intelligence in Spanish, without installing developing versions. Apple’s artificial intelligence system lands in our language and in the European Union, and does it one day earlier. Although the company had announced that the deployment would begin in April, the activation has started this Monday, March 31 with the launch of iOS 18.4, Ipados 18.4 and Macos Sequoia 15.4. Now, we can use the tools that debuted in the United States in October last year. Smart writing, Genmoji, Siri improved and more Apple’s response to the rise of artificial intelligence after the launch of Chatgpt in November 2022 arrives with a variety of novelties. Some are already available, while others remain in development and should arrive with future software updates. In any case, this system aims to mark a turning point within the company’s ecosystem. Writing tools. One of Apple Intelligence’s key functions are its writing tools. The AI is able to review our texts and generate different versions of the same content. It can be especially useful when we seek to refine a message, such as responding to an important email with the fair words to fulfill its purpose. We can invoke writing tools from almost anywhere where we can introduce text: from mail, telegram, bear or even Word, just press in the text box or touch the Apple Intelligence icon when it appears. Interestingly, in our tests it has not worked in WhatsApp, where Meta has its own AI. Priority notifications. It is no secret: we live surrounded by applications, and many of them saturate us to notifications. Apple has been improving the management of notices with each version of its system, but with Apple Intelligence it takes one more step with the priority notifications, which place the most relevant at the beginning of the list and in summary format. Can be activated from Settings > Notifications > Prioritize notifications. Priority messages. Something similar occurs with our entrance tray. Now Mail incorporates priority messages, a function that shows in the upper part those emails that care the most. In addition, with a simple touch we can also get a summary of the mail content. How to activate Apple Intelligence in Spanish and Spain Now that Apple Intelligence is already officially available in Spain, it is no longer necessary to use it in English or install beta versions. Starting to explore your functions is very simple: it is enough to update the devices to the most recent version of the system. In the case of the iPhone, it is iOS 18.4; on the iPad, of iPados 18.4; and in the Mac, of Macos Sequoia 15.4.The steps are the usual: On iPhone and iPad: Settings > General > Software update. In Mac: System settings > General > Software update. Once updated, it only remains to be waiting for the language models that support Apple Intelligence. Of course, not all devices are compatible. Apple Intelligence is available only on the iPhone 15 Pro, 15 Pro Max, the entire iPhone 16 range, the iPad Mini with chip A17 PRO, and the iPad and Mac with M1 or higher processor. If you have a previous model, you can install the system update, but Apple Intelligence will not be activated. In development. Images | Apple In Xataka | Apple Intelligence is a “fire” for Apple.

The United States has decided to start a tariff war. Videogames in physical format will pay Caro

March 8, 2025 by usatoday24

Practically from his inauguration as president of the United States, Donald Trump launched a series of tariff measures that put many of the countries with which he maintained commercial relations. Very soon, the ESA (Entertainment Software Association)of which companies such as Xbox, PlayStation, Nintendo or Ubisoft are part of the evil, warned how bad these economic impositions can sit to the industry, mainly due to the conditions of globalization that the sector is experiencing. More tariffs, it is war. The Toma and Daca between countries that maintained a fluid commercial relationship with Trump has just begun, and we recently knew that if the US imposed 10% on Chinese productsthey responded with others in the opposite direction of 10 to 15% For American products such as coal, gas or oil. Similar answers They have given themselves after the announcement of the 25% tariffs for Canada and Mexico. ESA said it. The association warned In a statement that “tariffs on video game devices and related products would negatively affect hundreds of millions of Americans and damage the important contributions of the industry to the US economy.” And although analysts like David Gibson, from MST Financial said On Twitter that the tariff to China would have a “zero impact” on the price of the Nintendo Switch 2 In the United States, it also left the door open to the thing could change if tariffs like countries like Vietnam remained, very important for the manufacture of the console. The problem: physical games. The physical games market is increasingly a more residual part of the industry. But the thing could get worse. Analyst Daniel Ahmad He has highlighted that 20% of Chinese products would undoubtedly affect technological products such as consoles, mobiles and gpus (the latter It is already being noticed), while the 25% that Trump plans to carry Mexico would have an unsuspected effect: in the manufacture and consequent increasing discs, where the Latin American country has an important weight. Less and less. Mat Piscatella, another video game expert analyst, Replica these Ahmad predictions With an even more disastrous prediction: “I would not be surprised to see that the physical games subject to these rates simply did not get to do, with the editors addressing a completely digital strategy.” And concludes: “What a disaster.” At the moment, they are only conjectures, but analysts seem to coincide that tariffs could have an unwanted effect on precisely North American editors, which is what this policy tries to avoid. A future without physical format. Maybe this is the last lunge that awaits the physical games. The digital format gain ground Without rest, and the figures could not be clearer: in 2023 95% of the video games that were sold did so through digital roads. And decisions like Sony’s launch the PS5 Pro without disk unit (You have to buy separately) or Microsoft’s launch A new model Of Xbox Series S also without an album, they make it clear to which direction the industry is.

The uranium is listed up after the nuclear resurgence. And a company wants to start extracting it in Greenland

March 5, 2025 by usatoday24

While Trump Keep with your speech to buy Greenlandiamining remains prohibited in the country. However, this decision may change by imposition of a judge. Short. The Energy Transition Minerals (ETM) company, formerly known as Greenland Minerals, has filed a millionaire demand against Greenland for the care of his project at the Kvanefjeld site. The company has demanded that the mine be allowed to exploit or receive compensation of 11.5 billion dollars. The dispute has reached an international arbitration under the dispute resolution system between investors and states (ISDS). The competent court to resolve the case will be the one established under international arbitration agreements between investors and governments. In depth. The company acquired the rights to exploit the Kvanefjeld site. This reserve is one of the largest in the world not exploited that contains uranium and rare earths. However, in 2021, the Greenlandic government prohibited uranium mining. Currently, the lawsuit accuses the country of illegal expropriation and for the moment the case is in international arbitration, initiated in 2022, but has progress slowly due to prolonged disagreements about the procedure. This summer, the referees will decide if they must accept the case. If they do, it is likely to be resolved at the end of this year. Meanwhile, the decision is dividing the population with nearby elections that could change this resolution. The complaint system. This arbitration system, designed originally to protect foreign companies of abuse by governments, it has been increasingly used to demand the states that adopt environmental laws. In several cases, companies They have sought millionaire compensation for the closure of mining projects that considered profitable. In this way, international arbitration It has become In a lucrative area of international law, with multimillionaire payments to companies that require compensation for the losses attributed to regulatory or environmental changes. The history of uranium. Mining has meant a problem For Greenland for pollution. As of 1970, the first deposits of lead and zinc began to exploit, which has caused irreversible damage in the flora and fauna of the area. For this reason, when ETM acquired the rights to exploit the Kvanefjeld area in 2007, the local population was alarmed by the environmental impact it could cause in drinking water and in the farm farms. If the mine reopens. In case they return to work on the project, the exploitation would be done in the open, which implies removing large amounts of rock to extract terbio and neodymium, key metals to manufacture magnets in wind turbines and electric cars. However, in doing so, uranium would also be unearthed, which would generate radioactive waste. From the company itself, has explained to The Guardian that “will use the best environmental practices” whenever it is “technical, practice and financially.” The international game. While Greenland face again To the United States after the statements of the US president to “take the country in any form, now he will have to stay aware of how the trial on the exploitation of the Kvanefjeld site will be resolved. However, this sentence must be seen with magnifying glass, because the company Energy Transition Minerals (ETM) is partially owned by Shenghe Resources, a company backed by the Chinese government. So, Greenland is trapped between the interests of China and the United States. For its part, the government opposing uranium mining, demonstrating Your concern for the environment and the future of the sovereignty of the country.

The future of quantum computers depends on helium-3 from the Moon. There is already a plan to start bringing it in 2029

January 27, 2025 by usatoday24

Helium is the second lightest and most abundant chemical element in the universe, if we stick to ordinary matter. It is only surpassed in this classification by hydrogen. This noble gas accounts for between 24 and 26% of the total mass of stars, which are also responsible for manufacturing it. fusing hydrogen nuclei inside through the reactions of nuclear fusion that they carry out naturally, and which we talk to you about in quite some depth in the article that we dedicate to the life of the stars. Still, most of the helium in the universe was not made by stars: it was produced by the Big Bang, which is why scientists refer to it as “primordial helium.” But the most curious thing is that, despite how abundant it is in the universe, it is scarce on Earth. Its great lightness caused most of the helium contained in the cloud of dust and gas from which our planet was formed to escape gravitational confinement. Be that as it may, the real protagonist of this article is not the normal helium that we have all heard about; It is helium-3, an isotope that may play a crucial role in nuclear fusion reactions that will possibly help us solve forever our energy problems. And also in other areas, such as, for example, in dilution cooling systems that use superconducting quantum computersas well as other emerging technologies. Interlune plans to test the extraction of lunar helium-3 in 2027 Most of the helium that we can find in the universe has taken the form of an isotope known as helium-4, which is characterized by having two protons and two neutrons in its nucleus. Although, as we have seen, most of it was lost during the formation of the Earth, this gas can also arise as a result of natural radioactive decay of heavier chemical elements, such as uranium, radium or thorium, which are relatively scarce on our planet. The only difference between helium-4 and helium-3 is that the latter isotope has one less neutron in its nucleus. That’s all. We know that helium-4 nuclei have two protons and two neutrons, so helium-3 nuclei will have two protons and a single neutron. It may seem like an irrelevant difference, but it is not. It is a very important difference because the physicochemical properties of the element vary as a consequence of their lower atomic mass. And, in the case of these two isotopes of helium, their behavior also changes from the point of view of quantum mechanics. The solar wind spreads helium-3 throughout the solar system and beyond, causing it to reach surrounding planets in relatively large quantities. The bad news is that if helium-4 is relatively scarce on Earth, helium-3 is even more so. Stars, like our Sun, produce it in large quantities as a result of nuclear fusion reactions between hydrogen nuclei that occur when they are in the main sequence stage during which they burn most of their fuel. Once created, the solar wind spreads helium-3 throughout the solar system and even beyond, causing it to reach surrounding planets in relatively large quantities. The reason why this gas hardly accumulates on Earth is that our planet has a double protective shield: the atmosphere and the Earth’s magnetic field. These two barriers represent a very effective defense against the solar wind and cosmic radiation, which reaches the atmosphere mainly in the form of protons and high-energy alpha particles. The Moon, unlike the Earth, has no atmosphere, so it lacks this protective shield. Additionally, its magnetic field is much weaker than Earth’s and is not dipolar. The terrestrial, on the other hand, can be approximated to a magnetic dipole, so the magnetic field lines are directed from the north pole to the south pole. All this causes the surface of the Moon to be much more exposed to cosmic rays and the solar wind than the surface of the Earth, causing very significant quantities of helium-3 transported by the solar wind to accumulate there, which is deposited in rocks and lunar dust, a few meters deep. Up to a million tons of regolith need to be processed to obtain a single kilogram of helium-3 The first challenge that humanity will have to solve to appropriate the helium-3 accumulated on the Moon is none other than the processing of lunar regolithwhich is the loose layer of soil and rock fragments that covers the surface of the satellite. Interlune, a company founded in Seattle (USA) in 2020, plans to extract the regolith and process it using compact harvesting robots that, according to this company, are very efficient. The problem is that lunar dust is very abrasive, and, in addition, up to a million tons of regolith must be processed to obtain a single kilogram of helium-3. Even so, this company plans to test the extraction of this isotope with a lunar mission in 2027, and in 2029 it intends to build a pilot plant on the Moon. It sounds good, but a priori these dates seem excessively optimistic. Additionally, it is still unclear how much it will cost to transport lunar helium-3 to Earth using space vehicles. Be that as it may, we can be sure that it will not be easy or cheap to do so.
