problems

The Tesla Robotaxi has been in the street for less than 72 hours. Is already being investigated for security problems

by

On Sunday, June 22, Tesla will begin publicly in the Robotaxi race. The company put, for the first time, its completely autonomous cars on the street. Since then, they operate with a handful of vehicles to a group of people previously chosen. In less than three days, they are already being investigated. June 22. It was the first day that Tesla’s robotaxis started walking through the streets of Austin. And although the promises in recent years had been grandiloquent, they did it within the regulations. That is: a handful of cars, a handful of chosen people and a handful of travel. Although something like that could be expected, the company’s first steps in the sector are still far from the Cybercab Promised, artifacts without flyers or pedals that should act as a kind of ships with wheels that take you anywhere inside a city. Let’s not forget that Elon Musk promised that we would see this in 2026. Under investigation. In less than three days, the NHTSSAthe agency in charge of security in the United States has opened an investigation to make sure that these vehicles are safe, they explain in Bloomberg. The reason is the slightly erratic behavior of some cars. At the moment they are only preliminary reports, they point out from the economic environment, but the NHTSA already warns in their response that they will take measures if they consider that the safety of passengers and the rest of the traffic agents are being endangered. Moment in which Tesla Robotaxi circulates in the opposite direction. Click on the image to go to the original tweet In the opposite direction. One of the reasons that has led NHTSA to the work table has arrived with a video published on social networks in which a Tesla is seen that doubts when taking a left output, to which it is bound at the intersection by the previously chosen lane. After hesitating, it moves to the right and enters a lane where cars circulate in the opposite direction. Subsequently, a double continuous line is skipped to return correctly. The entire incident can be seen in the Tweet published by Rob Maurer in which he shows without cuts a trip of more than 20 minutes aboard one of the robotaxis of Tesla. Specifically, Tesla’s doubts and erratic behavior are found in the 7th and 15th minutes of the recording. Many lights and some shadow. Except for this incident, in the rest of the video you can see how the car behaves with a lot of ease between traffic and that does not usually hesitate to take a way out or in which lane should be positioned. Nor does it give the feeling of circulating at an abnormally low speed or hindering the rest of the road agents. Despite this, we must bear in mind that the trips that have been made are very few and with very chosen people. In fact, Maurer himself is known for having had a podcast focused exclusively on the company. Sawyer Merritt, who looks in his biography of X that he is Tesla’s investor, He also published a video in which the car is seen exceeding the maximum allowed speed in a street after exceeding a signal that reduced the limit to 30 mph. Zero error. Actually, the two incidents have not put anyone at risk but NHTSA research gives an idea of ​​strict security measures that regulators want to demand from companies that put their cars on the street. Hence the Waymo and Cruise developments They were extended for years and that the tests are limited in space or in time. Keep in mind that a small mistake with a car can generate important damage to a person and that we ask the autonomous car that is much safer than the human driver. In fact, the company itself assured in the presentation of Tesla Cybercab that “Mobility stinks” because, among other things, “it is not sure”. That firm control of regulators is the one that forces Tesla to breach their own promises. That is, they have to circulate with humans and cars with flyers and pedals. But also that the area of ​​use is very limited and that the service between six in the morning and midnight. Question of time. The publication of the news made Tesla’s actions slightly down. The same ones that had risen since Sunday after the finding that the robotaxis service was launched. However, this fluctuating movement is relatively absurd since it is a matter of time that a company robotaxi is immersed in an accidenteither because of yours or for an unexpected movement of any other traffic agent. It is something that all companies of this type have to deal with but the problems They took Cruise ahead and Xiaomi and the rest of the manufacturers They were attracted attention by the institutions after Three passengers died aboard an Xiaomi Su7 which seemed to be working with activated driving aid systems. The NHTSSA and TESLA. Nor is it the first time that the NHTSA and Tesla look at the faces. The company has been accused of “Delivery advertising”together with other manufacturers, because the name of Autopilot overalls the real capacities that their cars can offer to the general public. But Tesla has also gone through the NHTSA scrutiny due The autonomous driving system was deactivated not to leave a trace of its involvement in shocks. The company has also always played to the limit of legality in some aspects, such as using your own customers like Beta Testers In the streets before making officers the updates of your Autopilot.

Germany believes having found the most German solution to its productivity problems: work more

by

Germany has been considered for decades as The economic locomotive from Europe. However, currently It crosses a crisis that has surprised analysts and experts. The model that allowed the country to prosper with reduced working hours and shoot its productivity, seems to have reached its limit. German leaders They look for new formulas To recover lost growth and have found a possible solution: work more. Germany works little. In recent months, the economic debate has intensified without the German responsible having found the key to getting out of the economic stagnation. However, from the business circles of Bavaria, southeast of Germany, they point out that it could be something as simple as increasing annual work hours. The formula: eliminating one of the religious holidays of the German calendar. According to published the newspaper Welt, Federal Foreign Minister Friedrich Merz would agree with this statement: “In this country we have to work more and, above all, more efficiently,” said the president in a few words that Later he clarified “But in Germany we have groups, especially among the youngest generation, which work a lot.” They have tried everything. The pilot tests of the four -day work week They have not achieved the Productivity impulse that the country needs. Foreign Minister Merz recently warned: “With the four -day week and the balance between professional and personal life we ​​will not be able to maintain the prosperity of this country,” declared The German Chancellor to I monde. This statement has generated discomfort in a society that has always been considered hardworking and disciplined. For decades, German workers have enjoyed shorter working hours compared to other European countries, especially those in the south. This situation was justified by high productivity and added value of German products and services, which allowed “doing a lot.” However, the economy fails to take off and the government now points to “lack of work” and “preference for leisure” as factors that are ballasting economic growth. Eliminate holidays. Before this panorama, some voices of the business have proposed concrete measures to increase the working time Without increasing working days daily, which in many cases are already more than 40 hours due to the enormous load of overtime. According to published BildBertram Brossardt, general director of the Bavarian Business Association, suggested to eliminate, at least one of the holidays that the Germans have. “Easter Monday, Monday of Pentecost and San Esteban. My colleagues in France and Italy are constantly surprised that we have those free days. Removing one of those free days would greatly benefit the German economy and would not mean a heavy burden for employees,” said Brossardt, adding that “religious festivities should not be taboo in the debate.” The data support it. The proposal is not just symbolic. Christoph Schröder Researcher at the German Economic Institute (IW) He maintains that Eliminating a holiday could increase the Gross Domestic Product (GDP) of Germany by up to 8,600 million euros. According to published The avant -gardeMichael Hüther, director of the IW, gave as an example the case of Denmark, which had recently eliminated a holiday “that was an additional income of 400 million to the state budget,” said the economist. The problem is that all federal states in the country, regardless of setting their own holidays, should agree to abolish it. Germany to the tail at hours worked. Brossardt’s arguments rely on blunt data. In 2023, a German employee worked an annual average of 1,343 hours, which is 92 hours less than in Austria, 186 hours less than in Switzerland and 391 hours less than in Italy, According to OECDE data. “We are not productive enough. If we want to be competitive, we have to return to work more!” said The businessman to the newspaper Bild. Despite these figures, Germany is not the country with more holidays. On average, the Germans enjoy 9 national holidays, although in some southern regions such as Bayern, Basen-Württemberg or Saarland can reach 12 holidays. In comparison, Austria and Malta enjoy thirteen holidays. In Spain, the usual are twelve, with some autonomous communities such as Catalonia, Community Valencian and Navarra add 13 holidays; Ceuta has 14 holidays a year, while the Canary Islands conform to 11 days. Average weekly hours worked in each country The problem is not the days. Such and as he published The confidentialsome experts do not believe that eliminating a holiday is the solution for the German economy, but that the country must face a change in its labor market to recover the productivity of yesteryear. Germany is the second European country where less hours work a week in full -time jobs, and the figure drops even more if the Part -time contracts. According to official dataone in two women works part -time in Germany. Therefore, some economists propose Encourage the incorporation of women to the full -time labor market and facilitate the arrival of more foreign workers to relieve the shortage of qualified labor. The key, according to these experts, is a deep review of the German labor market to adapt to the new challenges economic and demographic that supposes the Agence of the active population.

The Valencian Community has a single inhabited island. And when summer comes tourism is the slightest of its problems

by

Tabarca is a special island for many reasons. By its sizejust 1,800 meters long, a few hundred meters wide and an area of 0.3 km2. For its condition of Only inhabited island from the Valencian Community, although its census barely goes from half a hundred of neighbors. And for the particular situation that lives in the tourist stage of the Costa Blanca. Although in summer Tabarca receives thousands of visitors a day, its main problem with tourism is not the massification but The deficiencies suffering from the archipelago and worsens with the arrival of heat. Tabarca is a unique island. And not always for good. In a place in Alicante … Tabarca is a small island on the Alicante coast, located scarce Eight kilometers from the port of Santa Pola. And the “little” is more than justified. The island is around 0.3 km2 and the entire archipelago barely passes from 1,800 m long and 400 wide, which can travel from top to bottom in A small walk. Its size and their population, of just over fifty people (According to the INE There are 34 men and 25 women censored there) they make it an exceptional case. It often presents itself as The only one Populated Island of the Valencian Community and The smallest of the country with permanent population. Its location, beaches and landscapes also make it something else: a busy destination in summer. A figure: 10,000. One thing is the autumn tabarca, winter and the principle of spring and a very different summer tabarca. When the heat arrives, the island becomes a defendant destination. Both in fact that the transfer of bathers and families multiplies exponentially. Some estimates talk that in summer peak days exceed 5,000 visitors. Others raise it to 10,000. It is good for one or another figure, in October that translates into a tourist pressure that far exceeds its register. The figures handled by the local press do not always coincide, but are equally blunt. Some estimates point to more than 150,000 visitors during the summer months or even 230,000 Throughout the year. The influx of tourists also concentrates on a Very concrete season: The drip begins towards Holy Week, with the arrival of retirees of the Imserso, continues among the ends of spring and the beginning of summer with the schoolchildren and intensifies in the warmest months with visitors attracted by the beaches. Is it a problem? The tide of tourists has sneaked into the public debate of Alicante, with Voices in favor to control access to the island and apply “limits to the number of visitors” daily, a measure that already applies in other parts of the country, such as in the CIES, in Galicia. At least a year ago the Almeria City Council It was not shown However, too supportive of afor and restrictions. Others bet on DestationalizeThe demand for the bulk of tourism not to concentrate in the summer months. “The island needs a more balanced approach that considers not only beach tourism, but also ecotourism and cultural tourism, which can help distribute the load of visitors more uniformly during the year,” he said In 2024 Alejandro Triviño, from the University of Alicante, to Information. In his favor Tabarca has more than beaches. It is considered Marine reserve Since 1986 and enjoys an interesting story that links it to Berber pirates and Genoese fishermenin addition to A rich heritage which includes The wall or the Church of San Pedro and San Pablo. Something more than massification. However, the big problem of Tabarca is not the massive influx of visitors, but how they arrive and what they are once land. I explained it yesterday The country in An article Remember that the main challenge of the island in tourism is the deficiencies that it drags, a few deficiencies is that they become even more visible when the heat comes. “The problem is not tourists,” Recognize to the Diario Carmen Martí, president of the neighborhood association. “We need a comprehensive plan that condition the island for inhabitants and visitors.” The reason? In summer Tabarca receives a tide of travelers willing to spend the day on their coasts, but unlike what happens in other Arenales of Alicante, on the island –Martí complaint– They do not have some basic services. “Public toilets, shadow areas, tourist attractions such as the church or the vaults of the wall are closed, the tower is in ruins …” insists The neighborhood leader before adding one more task to the list: regulate displacements and a public transport service. “How 40 years ago”. Martí is not the only one who thinks like that. The owner of one of the island’s restaurants Recognize to The country That Tabarca has gone from being a small community that basically lived from fishing to a hyper tourist destination, but that transformation has not come accompanied by changes that make it more assumed for the locals. “Many people come and we are like 40 years ago,” Reflect. “We need a larger port, to separate the tourist from goods ships and more cultural activity so that the visit is not only sun and beach.” The list of resident requests is wide. They talk about transport, pricing disparity with which visitors are and the cost assumed by those who work on the island, of public services as basic as medical assistance or public spaces (picnic or even shadow areas) in which visitors can protect themselves during the warmer afternoons of the summer. Is it something new? No. It comes a quick search to verify that the complaints of the neighbors are not new. A year ago, during An interview In Onda Cero, Martín explained that the Island supports a tourist pressure similar to that of “any tourist area of ​​the Peninsula”. “The problem is that it is not prepared to welcome with guarantees the numerous visitors who agglomerate mainly during the months of July and August,” warns the representative of the neighbors, who regrets that “the impression that … Read more

More and more are those who visit Antarctica. We have just realized the magnitude of the problems they cause

by

We often hear about the damage suffered by the Antarctic ice layer, especially as a consequence of climate change. However, the icy continent is not only changing on the surface. The impact of the human being can also be noticed in the depths New images. A team of researchers He has published images of the seabed in the immediate vicinity of the Antarctic coast in which the effects of human activity in the region can be seen. Specifically they show us the impact on the marine soil that the anchors of the ships that arrive in the coasts of the southern continent. The problem is not simply landscape, it also affects the sea life of the seabed. The team showed special concern for the communities of sponges that inhabit this remote region of the ocean. Unprotected environment. The trail of human activity in this region is the result of various changes in the environment of the Antarctic Ocean. On the one hand, climate change has made waters that once remained vetoed to navigation are now accessible not only to oceanographic ships and breakfast but Also to tourist and recreational vessels. According to the team, during the 2022-23 season, at least 195 tourist, scientific and fishing vessels approached the coastal region in which possible to throw the anchor (areas with depths of no more than 82.5 meters). After the trail of ships. The group of researchers used underwater cameras to study 36 points of the seabed located in the vicinity of the Antarctic Peninsula and San Pedro Island (or Georgia del Sur). As explained, The images Captured to different depths showed disturbances both in the seabed and in underwater life, a consequence of the anchors of the ships that arrived in the environment. “The documentation is late, given the importance of these ecosystems and the protection we assign. The impacts of anchoring are infrastudiated and underestimated globally. It is important to recognize and mitigate the impacts throughout all industries and limit planned anchors,” explained in a press release Sally Watson, co -author of the study. Analysis details have been published Through an article In the magazine Frontiers in Conservation Science. Sponges in danger. The anchors are a risk to the life that extends in the seabed. According to the team, the affected areas showed few signs of marine life. What they did find were the traces of colonies of crushed sponges By effect of the arrival of humans. In contrast, in the adjacent areas “marine life flourished”, they emphasize. Especially vulnerable. An added problem is in the fact that life in these cold environments (part of this endemic life of the environment) tends to be slow growth, which makes it especially vulnerable to these types of problems. An example is found in volcano sponges (Anoxycalyx Joubini), A species found by the team in their expedition to which specimens belong that can be considered among the oldest living animals: they can reach 15,000 years of age.

The rent has risen so much in Galicia that its beaches have problems hiring something fundamental: lifeguards

by

The tourism industry has faced for a long time A worrying dilemma In Spain (as in other countries): as its main destinations grow and gain attractive, The price goes up of the accommodation, which makes things more and more difficult for workers who support the sector. We have seen it In Tenerifewhere there are hoteliers who are forced to Sleep in caravans For the high cost of rentals. And we see it now In Galiciawhere housing is affecting an even more sensitive group: lifeguards. Although in the official registry of the community there are registered Thousands of lifeguards Prepared to monitor the beaches, some locations are costing to sign them. And one of the reasons is the high price of rentals on the coast. Costs. The news He has revealed it The Galician mail: Although the official registration of the Xunta has more than 4,500 inscribed lifeguards, a record that exceeds 13% to those accounted for in 2024, there are areas of Galicia in which it is not easy to “sign” professionals. It is not a general something. In fact there are municipalities that have covered their vacancies well. But there are certain points in the region in which not even this abundance assures them to find vigilantes. And what is the reason? There are several factors at stake. Input, how the population is distributed. Not all municipalities have the same bag of inhabitants and, therefore, of neighbors with the lifeguard title willing to cover sand sands that remain close to their homes. Another key is working conditions. The salaries are around 1,200 euros per month, according to Precise The Galician mailand they are hired for very short periods, from two to three months. These circumstances lead to professionals who choose to move to other more southern or warm destinations, such as the Canary Islands or Andalusia, in which they can opt for six -month jobs or for full years. To solve it there are those who even has raised The possibility of betting on “a permanent body” of lifeguards who cover the heat months, more extensive. Another handicap that affects the sector is the bureaucracy: the longer the aid takes, the greater the risk that the lifeguards have sought alternatives. Housing slopes. The above are, together with the regulatory issues of the sector, the factors that have marked the guild in Galicia in recent years and explain that the region has suffered shortage of lifeguards. Now one more factor comes into play. The mail assures that this summer the consistors are proving easier to sign vigilants, but where the reason has been found with difficulties is another: the housing price, In full climb. The general price increase in Galicia as a whole, 7.1% in the last year According to idealistadded to the high seasonal demand of coastal destinations during the summer months, Galician lifeguards who have to leave their locality and rent a floor. In practice that hinders hiring in localities that have to ‘import’ lifeguards out. Is the house so expensive? A few days ago Technitas published A report in which he points out that an 85 m2 apartment on Riazor beach (A Coruña) reaches € 1,400 per week, one hundred more than last year. In Vicedo (Lugo) a 65 m2 floor costs 650 euros, one hundred more than a year ago, and in O Grove (Pontevedra) a 75 m2 house requires a disbursement of 950 euros per week. The report speaks of vacation leases, but that scenario fully affects seasonal professionals who, like lifeguards, seek accommodation for a few months. Beyond Galicia. It is not a problem that affects only Galicia. Recently Antena3 He spoke With José Luis, a lifeguard who has been in Ibiza for 25 years and who has not left any choice but to buy a caravan to have a place to live. Renting an apartment is discarded, he explains, because it costs more than he earns with his watchman work. Even the caravan option begins to complicate. “Being in a campsite costs me about 1,800 euros per month.” “This is something that happens throughout Spain and the most affected places are the ones with the greatest tourist influx, such as Balearic Islands, Valencian Community and some areas of Andalusia and Catalonia,” Confirm to The mail José Palacios, coordinator of the Research Group in Aquatic Activities and Saporrism and President of DEAC, the entity responsible for granting the blue flags to the sand. Healing in health. To make sure they will have lifeguards there are consistories that directly choose to form them. This is the case of Ribeira, in the Barbanza region, which in 2024 and 2025 He has conducted courses Own who have allowed him to prepare the young people who will be in charge of controlling the sands of the region. Another strategy to prevent them from opting for less seasonal destinations is to expand their work period: instead of hiring them in July, they are incorporated into their positions in June, when many beaches of Galicia begin to fill.

The anger between Musk and Trump has made Tesla lose 100,000 million dollars. Is the least of his problems

by

Elon Musk and Donald Trump have staged for hours a breakdown of a bloody divorce. With accusations exchanged in which it has threatened to withdraw aid to electric cars, the Disassembly from the International Space Station And it has come to the fore to Epstein’s namethe afternoon has been moved in the United States. The clash has mobilized the entire Maga Movement In favor of each other (including the request of the Elon Musk deportation). And, in the middle of all, Tesla. 14%. Without a doubt, the afternoon figure in the United States. That is what The actions of Tesla came to fall Although, at the end of the day, there was a small rebound that left the action losing more than 11 % at the end of the day. Thus, the price of the action started the day exceeding $ 322 and closed it by $ 284.70. If the final rebound had not occurred, we were talking about the shareholder would have left another 10 dollars per share. However, it is estimated that Tesla has left some 100,000 million dollars Yesterday. On a personal level, Elon Musk has seen 34,000 million dollars volatilize with his discussion yesterday. Although we focus here on Tesla, we must not lose sight of the US government contracts with Starlink or Space X. The youngest of the problems. In total, it is estimated that Tesla has lost $ 100,000 million in the last fight between Trump and Musk. The dialectical crossing has caused a socavon in the graph of the actions but that is not the greatest of the problems. Now, with Trump as an enemy of Musk, Tesla has to row in a complicated scenario. The Robotaxi. It is the first indicated. Elon Musk announced that The first deployment of the robotaxi Tesla would take place in the city of Austin (Texas) whose mayor is from the Democratic Party But there are more derivatives that are intimately linked to the expansion of the service. However, The Governor of Texas is a republican And, in fact, the State is one of the bastions of the party. To this is added that NHTSSA is a state entity in charge of appraining the novelties that want to apply to circulate on the road. With their decisions, for example, it forces operators to have flyers and pedals In their cars, something that I wanted to eliminate Elon Musk in his robotaxis. The NHTSSA. The National Highway Traffic Security Administration (NHTSA) is also responsible for carrying out the accident investigations that occur when driving aid systems are active and has actively pursued the highway of Tesla. Its financing depends on the United States Congress and depends on the Department of Transportation that is directed from the Government. In addition to the previous investigations, it is the one who is approved so that a vehicle can work with a higher level of autonomy. For example, it is the one who rewarded Mercedes with the possibility of circular without the driver paying attention to what you have ahead. Yes indeed, In very specific circumstances. The aid. The withdrawal of the aid to the purchase of electric cars was something that, initially, did not seem to worry Elon Musk. Right now, the company’s leadership is so evident in the United States that they are the competitors of Tesla, who cannot offer the same autonomy-price relationship, Those who have to lose. However, it is clear that the withdrawal of aid can damage the sales of the company and Tesla is not in a position to leave sales right now. In Europe, Every month passing is a bleeding and In China its sales have also decreased To the point that Byd is already the brand that VWe are more purely electric cars In the Asian country. Regulatory credits. Another of the income roads that Tesla has been exploiting in recent years is the EMISSION CREDIT SALE. Donald Trump also showed his intention to prevent this type of practices that allow Tesla to draw income that since 2012 They have added 11,000 million dollars. When accountability before the institutions, companies have to meet emission objectives. If they exceed the maximum allowed figure, they can Buy emission bonds to companies that have not reached said limit. Thus, they lower their average emissions and avoid a strong fine. The beneficiary company receives the money from a competitor but although the number of emissions increases, of course, below the limit that marks the economic punishment. Goodbye to the Stock Exchange. Although it is not the biggest problem, the last six months have been a roller coaster of emotions for Tesla’s shareholders. At the end of 2024, the company closed the records in record, touching the $ 480 per share in mid -December last year. Since then, the controversial messages of Elon Musk, His Nazi greeting during the day Donald Trump took command of the United States or Your support for the AFD ultra -right party in Germany caused a sudden fallen that made us clear to what extent the image of Musk viciaba the stock market of the actions of Tesla. Little by little, the rumors of his departure from the United States government were already consolidating from mid -May, the shares consolidated the rise that had already begun in April. On May 7 the shares were worth $ 276. The confirmation that Musk focused on Tesla He lifted its price up to $ 363. In a few hours the entire climb has eaten. And what is expected. In addition to the obstacles that the United States government can put to the expansion of robotaxis, the elimination of regulatory aid and credits, it remains to be seen how the shareholders will receive divorce between Musk and Trump. Tesla is not going through her best moment. Its sales have collapsed in Europe And in China the rivals have been eating ground for a long time. It remains to be seen if the arrival of the Tesla Model … Read more

In case we had not had enough problems in the electricity network, a “severe” solar storm has come to complicate it

by

The closeness of the Pico de Activity of the last solar cycle implies stirred times in the field of “spatial meteorology.” And we have seen one of the most important during these days, a “severe” geomagnetic storm caused by this activity. Geomagnetic storm. The last two days have been days of “intense” solar activity. The geomagnetic storm has reached a Kp = 8 index, which implies that it has been a “severe” storm, from G4 category (On a scale that goes to G5). The value of the index has descended since then: the last data offered by the NOAA spatial meteorological prediction (National Oceanic and Atmospheric Administration) indicates that the value Average Index KP In the last three hours it has been kp = 6. Despite this, spatial time is still scrambled and According to forecasts He will continue to be until tomorrow. An ejection of coronal mass. According to He explained yesterday The Spanish Space Agency through a statement, the origin of this activity is in a high -speed coronal mass ejection (CME), associated solar fulguration of class M8.2 and with origin in the Ar4100 active region. KP 8. What does that mean of kp = 8? The K Geomagnetic Index measures disruptions in the land magnetic field and is used to characterize the magnitude of geomagnetic storms, especially through the planetary index K or KP Index. The latter uses a series of magnetometers distributed in stations located in various parts of the planet. The indices above kp = 5 are associated with a specific degree in the geomagnetic storm scale Employed by the NOAA SWPC, being G1 (minor) the smallest category on the scale and G5 (extreme) the category that denotes the strongest storms, those of index Kp = 9. A G4 storm. The storm recorded on Sunday, with a Kp = 4 index led the center to alert a “severe” or G4 geomagnetic storm. In your noticethe SWPC pointed out that, in addition to intense northern lights and lower latitudes than usual, possible impacts on infrastructure and networks, including problems with satellites and loss of precision in the GPS. The Category events They usually imply possible problems with voltage control that can also cause “mitigable” problems in electrical networks. At space vehicles, the SWPC indicates that these storms are associated with possible monitoring problems that require future corrections. Finally, other possible impacts are on the spread of HF radio signals and low frequency radio navigation. An active solar cycle. The situation has stabilized With ups and downs And, although the last one average three -hour data from the KP index is 6, the SWPC has already reduced the intensity of the storm to G1, or minor storm. The last months have been revolts as far as spatial meteorology is concerned. In October 2024, A similar situation He brought spectacular dawn. According to estimates From the experts we are already after the peak of activity of solar cycle 25, but we have not yet moved away much so the solar activity remains intense. Perhaps this is not the last storm of these characteristics that we see in the coming months. In Xataka | We have detected the exact date on which the most brutal solar storm occurred in history.

The problems of nuclear fusion are falling behind each other. Optimism cornering denialism

by

The challenges raised by the nuclear fusion intimidate. And it is to replicate on our planet and small scale the same reactions that take place in The interior of the stars It is a titanic challenge. Even so, The human being has already traveled A very important part of this path. There is a belief that defends that in the field of nuclear fusion we have barely advanced since World War II, but, as we will see in this article, it is not so. There is much to do, but we have advanced a lot. In order for electric power plants equipped with fusion reactors to be viable, it is necessary to solve problems that are still dealing with engineers. And it is that the challenges posed by nuclear fusion right now reside in the field of engineering, and not in that of basic science. In fact, Spain will actively participate In the search for the solution to one of these problems thanks to IFMIF-DONES (International Fusion materials irradicion facility demo-eraned neutron source), The installation that is under construction (Granada). Its purpose in broad strokes will be to develop a source capable of producing high energy neutrons with the intensity and volume of irradiation necessary to test candidate materials to be used in future fusion energy plants. This is one of the pending challenges, but many others have already been left behind thanks to the great work that scientists have carried out in experimental reactors, such as the already “retiree” JET (Joint European Torus), which is housed in Oxford (England). Let’s trust the reactor JT-60SA of Naka (Japan), and, above all, ITER (International Thermonuclear Experctor reactor), are up to expectations. Eurofusion and the University of Texas have made two new relevant contributions We can imagine in an intuitive way a nuclear fusion reactor as a pressure cooker in which two essential ingredients are cooked: deuterium and trity. To ensure that the nuclei of these two hydrogen isotopes merge and release the neutron that will ultimately allow us to obtain a large amount of energy it is necessary to confine them in an extremely hot plasma. In fact, so that this process takes place, a temperature of at least 150 million degrees Celsius must reach. Scientists know how to do it, so submitting the deuterium and tritium nuclei at the pressure and temperature to get me to merge is no longer a problem. What still represents a challenge is to achieve Keep turbulence under control. Otherwise, the plasma will be destabilized, its density in the critical regions will be affected and the support of the fusion reaction over time will not be possible. The mechanisms that govern this process are very complex, but little by little physicists and engineers who work in fusion energy are getting them better. The QCE (‘Quasi-Continuous exhaust’) regime is characterized by eliminating periodic instabilities that occur on the edge of plasma In broad strokes what they intend is to minimize turbulence so that the loss of plasma energy is minimal. Two of the tools that these technicians have are the artificial intelligence (AI), which is playing a very important role in understanding the mechanisms that govern plasma behavior, and Rebco superconductor magnets. In fact, The sparc fusion reactor that is building the American company Commonwealth Fusion Systems (CFS) uses them. Precisely Eurofusionthe European organization that is responsible for promoting and supporting the scientific research necessary to bring to fruition The European Nuclear Fusion Planhas recently made an important contribution in this field. And it has shown that in the reactors Tokamaklike Jet or Iter, it is possible to use an operation mode known as Qce (Quasi-counts exhaust) that is characterized by eliminating periodic instabilities that occur at the edge of plasma, and, at the same time, it supports high density in this region of gas and preserves a very high level of energy. Gradually the confinement and stabilization of plasma are no longer a problem. The other recent contribution in which I propose that we investigate it briefly has been carried out by a team of researchers from the University of Texas and the National Laboratory of Los Alamos, both in the US. In the article they have published in Physical Review Letters These scientists propose the creation of a magnetic confinement system without leaks ten times faster, according to their calculations, than the standard method without sacrificing a precision apex. This innovation is important because it helps to resolve the containment of high energy particles within the reactor, and, therefore, to avoid the loss of temperature and density in the critical regions of plasma. Yes, as I mentioned a few lines above, much remains to be done in the field of nuclear fusion, but definitely every day we are one step closer to commercial fusion energy.

After the mass blackout of Spain he feared looting and security problems. Reality was very different

by

Nor pillage. Nor Latrocinio. No chaos unleashed in the streets. Although most of the country stayed yesterday to two candles (literally) and Thousands of Spaniards They went to sleep yet without electricity in their homes and businesses, on April 28, 2025 will not go down in history because it is a day of chaos. Not everything was An oil raftof course, but this morning the Interior Ministry He underlined that the night has been “quiet”, “without remarkable security incidents.” Nothing that the country has not already lived during the pandemic, when Spain already demonstrated its obedience during the alarm states to stop the COVID-19. That almost a country is based black (in energy terms), as happened on Monday at 12.33 h in Spain, it obviously has multiple derivatives. It affects the industry. It affects trade. It affects mobility and education. And affects security. Yesterday the government declared The national emergency in eight communities and one of the issues that was in the public debate during the first hours was precisely The media deployment To guarantee security. “Security problems” “Madrid has 9,000 streets, 3.5 million inhabitants … If a city is these dimensions, we are all aware, we are all aware that they can give Security problems at very diverse and different points “, warned In the afternoon the mayor of Madrid, José Luis Martínez-Almeida. Without electricity, many businesses were left without a dataphone, but also without surveillance or automatic systems that allow them to close their premises. The fear of looting and robberies during the blackout even led some merchants to monitor their stores. In Ayamonte, Huelva, there were who The night passed In their businesses unable to lower the blinds and in Granada the newspaper Ideal speaks of entrepreneurs in a similar situation that resisted to leave their premises. “People take advantage of to steal and we have no system here that allows us to ensure the store,” admitted a ABC The clerk of a store in the center of Madrid while waiting for the supply to be restored. His suspicion was understandable. Click on the image to go to Tweet. After the Dana de Valencia there were those who took advantage of chaos to make looting and take home batteries, sports material, telephones or consoles, for example, sometimes even with truck help. Only the night from October 30 the National Police arrested 39 people During a surveillance campaign in commercial areas and weeks later, in mid -November, the number of detainees for looting in the areas affected by the rains over 400. It is not even necessary that an event as devastating as the DANA of Valencia occurs. In 1977 New York lived An electric cut which lasted for a day and resulted in a “night of terror”, in the words of the magazine Timewith the looting of more than 1,615 storesmore than 1,000 fires, around 4,000 detainees and hundreds of injured police. A few weeks ago Before a mass blackout also affected much of Chile, the Buric government chose to decree the state of exception and imposed a curfew between ten and six in the morning. In Spain the authorities also chose reinforce securityalthough without reaching such drastic measures. The Government Precise that between Monday and Tuesday they deployed through the country More than 30,000 agents of the National Police and Civil Guard, to which other forces of autonomic and local bodies are added. Click on the image to go to Tweet. In Catalonia Los Mossos d’esquadra They lengthened shifts and activated a night security plan with something More than 7,200 agentswhile there were cities that also increased their local endowments. In Vigo The mayor said Yesterday that the Local Police would triple their efforts and at night 13 municipal patrols would be deployed, to which almost twenty nationals would be added. What has been the balance? A relative tranquility. At least if one takes into account that, although part of the country began to recover electricity within a few hours, there have been cities that took More than 14 hours in having light and the day was marked by Communications problems and traffic lights. The total alert balance is not yet known, but inner speaks of a “quiet night and without remarkable incidents of security or public order” and both the Mayor of Madrid like that of Barcelona They have highlighted the “civism” of their neighbors. “The Madrid have shown that they give their best in the most difficult moments. In front of the blackout, a lesson of civility,” Almeida presumes. That does not mean that the last hours have been An oil raft. Eldiario speaks Of robbery attempts, activated alarms and “some” burning containers in localities of Andalusia and in the city of the emergency services had attended in the afternoon Double of calls of the usual, although Many incidents They were related to people trapped in elevators or people with mobility problems. In Other cities From the country and less inhabitants, the dripping of notices to the authorities throughout the day was also intense. The most graphic answer He has given it However, this morning, Mayor José Luis Martínez- Almeida when they have asked him about how the night had gone in the capital, in which, he says, only a reysta and a launa was recorded. “Quieter than anyone”, summarizes the councilor from Madrid.

Meanwhile, some players have been dealing with problems in their graphics for months

by

More than three decades ago, three engineers sat down to talk in Silicon Valley with an idea that would end up transforming the video game industry. Jensen Huang, Chris Malachowsky and Curtis Priem wanted to create a chip that would improve PC graphics. From that meeting Nvidia was born, and with it, the GPU as we know it. For years, the name of Nvidia has been synonymous with gaming experience in PC. If you have ever set up a computer to play, it is very likely that your graphics card will carry its logo. The brand has achieved something more difficult than technological innovation: build a faithful community that continues with enthusiasm every new release. Lately, however, something has changed in that relationship From the arrival of the RTX 50 series, with models such as The RTX 5090 and the RTX 5080complaints have been increasing. Many users have detected Failures in the controllersand the solutions do not finish arriving. In some cases it is possible to return to an earlier version to overcome errors, but those who have the most recent graphs do not have that possibility, since RTX 50 models are not compatible with the most stable previous versions, such as the 566.36. Reddit has become the center of complaintswith threads that accumulate testimonies of frustrated users. YouTube has also collected the echo of the problem With videos that document the problems. And we don’t talk only about noise on social networks: Nvidia herself has recognized Dozens of mistakes present in their latest drivers, which promises to solve in upcoming updates. Beyond the officially recognized problems, complaints about stability failures are frequent even among users of previous generations. Several players have reported black screens, unexpected reset, flickering, visual artifacts, load errors and forced closures in titles such as’Cyberpunk 2077‘ either ‘Star Wars Outlaws‘. The headquarters of Nvidia in Santa Clara, California Certain failures are related to specific configurations, for example, when using monitors with high soda rates, G-SNC activated or determined Displayport outputs, which complicates its diagnosis. All this comes after a premiere with stupy. Some RTX 5090 feed cables They have presented overheating. In addition, shortly after launch, some users detected that certain graphics cards of the RTX 50 series They had a lower number of rop units Regarding official specifications. Nvidia has confirmed that it is a manufacturing defect that affects less than 0.5% of models such as RTX 5090, 5090d, 5080 and 5070 TI. According to the company, the average impact on performance is 4% and does not affect artificial intelligence or calculation tasks. Nvidia main page in April 2025 (left) and in September 2018 (right) Meanwhile, the role of graphics in the Nvidia ecosystem is changing. They are still important, but they have stopped occupying the center of the stage. The company’s focus is now in artificial intelligenceand that shows not only in its public statements, but in the design of its website, which is far from what it was in 2012 or even in 2018. It is not the first time that a great technological is reconfigured. Microsoft, for example, had its nucleus in Windows for years, But it has diversified its portfolio of products and business units. That decision has been one of the keys that They have allowed him to stay competitive over time. Something similar happens with Nvidia. Founded in 1993, it continues to grow, it is still present and part of its solidity is due to the strategic decisions it has taken. With mistakes, with successes, but always in motion.
