Some of the most advanced satellites in the world seemed untouchable. Two hackers showed that they could be kidnapped

by

In satellites, each maneuver depends on software that is rarely subjected to public security evidence. Demonstrations in controlled environments have put vulnerabilities on the table that, under certain conditions, could allow the Remote Space Systems Control. It is not a timely failure or an isolated experiment: it is a sign that security should be reviewed with magnifying glass before it becomes news for wrong reasons. In August, during conferences Black Hat USA and Def with held in Las Vegas, researchers shared their findings, According to IEEE Spectrum. The work focused on two key pieces: the Core Flight System (CFS), used in NASA multiple missions, including the telescope James Webband Yamcs, a control system of the European company Space Applications Services. The failures, however, were identified and corrected before their dissemination. The finding reopening the debate on cybersecurity in space Behind the finding are Andrzej Olchawa and Milenko Starcik, experts from Visionspace with direct experience in space operations. They analyzed open source software with the mentality of an adversary, seeking reproducible vulnerabilities. They did not need months of analysis: in a few hours they managed to locate 37 failures that, in controlled scenarios, allowed to manipulate critical systems. They acted on their own environments and coordinated with developers to patch the software before disseminating their conclusions. The analysis of the Core Flight System (CFS) revealed that, although it is a key piece in NASA missions, its exploitation would not be simple. To compromise it would take toCceso Physical to a land station and operate at frequencies reserved for space communications. Even so, researchers warn that, in the hands of a state actor with sufficient resources and coverage, this scenario is plausible. In their demonstration they explained that, with that capacity, it would be possible to raise orders to the satellite and modify their behavior. Yamcs, unlike CFS, was more accessible to an attacker. The researchers showed that a campaign would suffice Phishing Successful to load a malicious configuration in the control center. With that entrance door they could issue arbitrary orders or alter files, all from any location with Internet connection. The exercise showed how this vector opens a much larger and less protected attack surface. In Black Hat USA 2025, Andrzej Olchawa deepened the reach of the tests and shared details on how vulnerabilities exploited. He stressed that All maneuvers were executed in simulated environments and that no real satellite was at risk. His explanation sought to give unlarmed technical context, showing precisely how far actors with sufficient knowledge and access to the right systems could reach. “In some cases, we were able to send arbitrary telecomandos to the ships through the mission control system. In others, we managed to take control of the entire control center and, in other cases, if you are able to send telecomands to the ship, you can get remote execution of code directly in it.” The threat panorama has changed: where there were private networks and local stations before, there are now remote control, cloud services and connections from home. This evolution multiplies the attack possibilities, according to researchers, and explains why theoretical vulnerabilities are now a reason for alert. An example is THE ATTACK AGAINST VIASAT IN 2022which affected thousands of users and coincided with the beginning of the war in Ukraine. The case suggests that space systems are not isolated from global conflicts. Corrections arrived on time for open projects, with updates that mitigated the techniques demonstrated in the laboratory. The pending challenge is in closed systemswhere the absence of access to the code limits the review by external experts.

The world is waiting for Depseek’s new great model to compete with GPT-5, but Depseek has other plans: the agricultural AI

by

At the beginning of the year, the Chinese startup Deepseek put the world of AI up with Deepseek R1a free and open source model that was placed at the height of GPT-4 or Claude. After the coup on the table, in Depseek they have been quite quiet, but now we know what its next objective is: the agriculture. Before the end of the year. A few days ago Bloomberg reported that Deepseek is working on an advanced and very ambitious agent. He will be able to perform multiple tasks with minimal user intervention and will learn as he works. According to sources close to the company, the founder of the company Lian Wenfeng is pressing his team so that the new agentic model is ready before the end of the year. The company has already taken a step in this direction with the Deepseek v3.1 presentation Just two weeks ago. As detailed by the company in A post in Wechatits new model improves performance in reasoning tasks and agricultural abilities. A step back. Deepseek R2, the expected successor of the successful model with which Deepseek revolutionized the industry making begging. Instead they gave us Deepseek v3.1 and now the rumors suggest that their next great launch will be an AI agent. What is happening? There are voices, such as This Chinese journalistthat they see this turn to the agricultural AI as a way of taking a step back and getting away from the expensive and competitive career of the foundational language models. That The generative AI is reaching its roof It is something that is being talked about Since last year. GPT-5 is the test more recent than The big jumps are a thing of the past. If we add to this that China has a more conservative way of proceeding, with more long -term strategiesDeepseek’s turn towards an agriculture instead of launching Depseek R2 makes sense. Restrictions Although we have seen The most ingenious forms to make fun of themUnited States restrictions on chip export to China are also impacting the plans of many Chinese and Deepseek companies do not get rid. This also involves extra pressure that forces new routes with which to market their products. In fact, there is something striking in Deepseek v3.1 and it is that the model has been specially designed for Chinese chipswith the objective of Avoid dependence on foreign chips. Generate income. The agricultural AI opens another way for Deepseek, one in which you can get benefits more easily. Large language models have a problem: They cost a money and monetize them is not being a simple task. Given this, IA agents rise like a Most reasonable business model. Deepseek R1 has already given a whole lesson in Resource efficiencyIt makes sense that the company wants to opt for the fastest path to the benefits. A more conservative position. Although He has trimmed positionsChina lags in AI in terms of investments and access to the most advanced chips. Despite this, his approach in this AI race is being different. We see it in your Bet on the Open-Source wave “Personified“But perhaps the biggest difference is that, while their competitors in the United States continue to squander billions, in China they are choosing to be more conservative and not waste. This turn to the agents is in that conservative line to achieve a more sustainable industry.

The most expensive cities in the world to live in 2025, explained in a very illustrative graphics

by

In 2025, the cost of living in some cities is a combination of high prices in goods, services and housing, which can only face who have income enough for it. For those who do not reach enough income to cover those basic needs that each city demands are dedicated to poverty or to move to other cities More affordable, something that is already beginning to happen in our country in large cities such as Madrid or Barcelona. The “Numbeo Index” Numouso is a database Collaborative that collects the prices of restaurants, services and goods in the main cities of the world and, based on this data, it produces listings in which you can analyze which cities are the highest cost of life, in which the price of housing has a greater impact or determining the economic effort of its inhabitants to live in them. For establishing a reference point in the comparison, Numbeo uses New York data as a reference value 100 in all its data. That implies that, if another city has an index of 112 in one of its parameters, it means that, in that parameter, that city is 12% more expensive than New York. If the value of the index is 88, it implies that it is a cheaper 12%. Based on these data, the portal Visualcapitalist.com has elaborated a graph in which it is clearly represented in what cities in the world is more expensive to live. The most expensive cities to live The graph prepared by VisualcapitalistNew York leads the global ranking as the most expensive city in the world. According to data collected by Numbeo, New York is positioned as the most expensive city, with a fork in the rent price ranging from $ 1,100 to $ 4,108 for an apartment in a room and up to $ 8,174 for a three bedroom apartment. The Swiss cities of Zurich and Geneva are followed in the ranking, with an index of the Cost of life more rental of 93.2 and 90.6 respectively, indicating that living in them is around 7 and 10% cheaper than doing so In New York. In the fourth position there is San Francisco (85.3) that sneaks between the Swiss cities of Basel (83.9) and Lausana (83,4). If we focus on more expensive cities to live From Spain including the cost of life, we find Barcelona in position 137 with an index of cost of life including rental of 48.29, followed by Madrid (47.38) that occupies the 142nd position of the global ranking. Palma de Mallorca (43,79) and Malaga (39,24) follow them closely, occupying positions 180 and 203 of the world respectively. The weight of rent when living in a city The price of housing is a determining factor when establishing the cost of living in a city. For this reason, the list changes completely when the data is filtered to unlink the cost of the home of the equation. In that scenario, New York no longer leads the List of more expensive cities to livebut goes down to seventh place. Those who do maintain consistency are the Swiss cities, which remain the most expensive in the world to live, with Zurich (112.54) leading the list, followed by Geneva (111,41), Basel (110,71), Lausana (110.55) and Lugano (108,38). From the Spanish perspective, all cities fall several positions indicating the impact of the rental price at your cost of life. Barcelona (with a cost of life without rent of 57.03) goes on to position 183, while Madrid (55.79) falls less positions until 187. In the case of Palma de Mallorca (55,13) and Malaga (48,02) the fall is just ten positions, indicating that the housing price impact It is less than in Madrid and Barcelona, ​​but the cost of the rest of the index factors (food price, Public Transportation Pricerestaurants, services, etc.) It is higher in these cities. Living in some cities is more difficult A very important fact that can be extracted from this database on the cost of life in large cities, is the purchasing power index, which uses the salary average of that city and compares it to the base reference that is that of New York. The result leaves us a photo of which citizens do a minor economic effort to live In a certain city. In this scenario, the inhabitants of Mannheim in Germany are the ones who must make less effort to live in the city with an index of 198.64, which implies that these citizens can buy 98.64% more goods and services than a New York with their salary. The Swiss Basel (194,85), Bern (186.76) and Lausana (180,45) sneak into the top five, occupying positions two, four and five respectively. Only truncated Swiss hegemony the city of Erlangen (189,69) in Germany, which is placed in third position. Spanish cities draw a slightly different panorama, being Valencia (131,73) Alicante (113,27), Seville (102.62) and Madrid (101,39) the only ones in which its inhabitants They have greater purchasing power than a New Yorker in the field of his city. On the other hand, Barcelona (88,37), Málaga (86,34), Palma de Mallorca (86,34) are cities where the opposite happens, its inhabitants have a lower local purchasing power rate by having a lower average salary and a higher life cost.

The fastest factory keys in the world

by

On the southeast coast of South Korea there is an installation that has somewhat redefined what the mass production of cars means. And it is that the Hyundai plant in Ulsan is not only the largest vehicle factory in the world if we talk about extension, but has managed to integrate manufacturing, quality control and global distribution in such an efficient process that today is capable of producing A new car every ten seconds. The figures speak for themselves. With a manufacturing capacity of 1.5 million vehicles annuallythis installation almost doubles all the production of vehicles of countries like Italywhich has about 23 different factories. To put this productive capacity in perspective, the ULASAN plant could have covered 98% of all sales of new cars in Italy during 2024. Image: Hyundai The secret is in integration. What makes Ulsan unique is not only its size, which reaches more than 485 hectares (the equivalent of 680 soccer fields), but its revolutionary concept: it is the only automotive plant in the world Integrated own port. While other factories must transport their vehicles to external ports, here the cars pass directly from the production line to the ship, eliminating dead times and logistics costs. Mass production. The installation houses five operational factories plus a motor and transmissions plant, with production lines that work 18 hours a day. 17 different models are manufactured, from the Hyundai Santa Fe and Tucson to the entire Genesis range. In fact, a sixth exclusive plant for electric vehicles will open during the first quarter of 2026 To produce genesis. From the line to the ocean in minutes. After passing the quality controls, the newly finished vehicles are directed to a huge parking lot next to the dock. There, specialized drivers They carry them on huge transport ships by steep ramps. Once the load is finished, these same drivers run away on foot and go up to an Hyundai Saria to go to the next vehicle lot. Complete urban transformation. The magnitude of the project has completely transformed the region. When Hyundai began the construction in 1968, Ulsan was a fishing village of 30,000 inhabitants. Today it houses 1.1 million people, and has become the industrial center of South Korea. The presence of Hyundai is so significant that there is even a highway with the name of the company’s founder, and hospitals, schools and restaurants proudly carry the name of the brand. Giant numbers. Every 24 hours A loaded ship comes out of the port of Ulsan. 75% of the annual production is exported to more than 200 countries, with destinations such as California, which receive up to 6,000 vehicles in a single ship after 13 days of crossing through the Pacific. The plant uses 34,000 people directly, more inhabitants than the entire city had when the factory was founded. An unrepeatable model. “This unique way of producing and exporting cars saves as much money and time, and it is the key reason why Hyundai can manufacture so many vehicles every year,” assured A person in charge of the plant. An efficiency model that began in 1968 as a small assembly installation where Ford Cortina was assembled by hand, and today represents the cusp of large -scale automotive production.

If the question is what salary the richest man in the world could have, Tesla has given an answer: 1 billion dollars

by

After the judicial battle that ended with the salary bonus block of 50,000 million that Tesla had to pay Elon Musk, the electric car manufacturer has launched an order to its shareholders with a New salary proposal For its CEO: a bill bonus (European billion) if you get the company out of the crisis in which it is mired. The potential value of the salary package that Tesla has presented Before the Bag and Securities Commission, it could raise the fortune of Musk, which is currently estimated at about 435.4 billion dollars, until it became The first billionaire in history If you manage to meet all the required conditions. The salary package conditions. He New salary plan That Tesla has proposed to Elon Musk does not consist of a traditional salary or cash bonuses: the entire figure depends on the flexible delivery of actions throughout the next decade, provided that it meets certain very demanding milestones, such as reaching Total sales of 20 million additional cars. All in the context of a company plunged into A sales crisis global. The shares will be delivered by sections, instead of the end of the period as it happened with its 2018 bonus, and only if Tesla manages to multiply its stock market value until it reaches at least one capitalization of 8.5 billion dollars, starting from the billion that is currently worth in the stock market. To put this figure in context, Nvidia is technological more powerful of the momentand its capitalization is 4.05 billion dollars. It’s not just money: it’s also power in Tesla. In addition, the plan could meet the historical demand of its CEO to have More power within the company. Currently, Musk control around 12% of the actions of Tesla. However, with the new salary bonus its participation in Tesla would increase to 29%. Increase your participation to that percentage would allow Musk increase your influence direct about the company. In this way, it would have enough weight to block important decisions that would not have their approval and further reinforce their position as an essential leader. In one recent interview For the CNBC, Robyn Denholm, president of the Tesla Board of Directors, made it clear to investors to “retain and encourage Elon is essential for Tesla to become the most valuable company in history.” Without a doubt, a salary package of such a draft should be enough to motivate the richest man in the world. Termination clause and a commitment to the future. Such and as they break down in Bloomberganother of the conditions of the new salary package announced by Tesla, it is established that MUSK must remain as CEO of Tesla During, at least, the next ten years to be able to opt for the entire compensation, with a minimum of seven and a half years to unlock the first section of the remuneration. “If it yields, if it reaches the ambitious objectives of the plan, it will receive a participation: 1% for each half billion dollars of stock market capitalization, plus the operational milestones it must achieve to achieve it,” Denholm explained. On the other hand, among the operational challenges that the commercial deployment of one million is found during that time of autonomous robotaxis and of the Optimus robots with integrated Grok, multiplying by 24 the current benefits of the company. Investors will have to vote. After registering the proposal to the regulatory body of the stock market, the next step in its process is to submit the salary bonus to the vote of investors. Something that is still more than A mere formal procedure since the previous 2018 salary package was also voted on a shareholders’ meeting, and finally It was canceled by a court of Delaware for the complaint of one of the shareholders.

Nvidia world leadership in chips for AI is brutal. In GPU for games directly has fulminated the competition

by

Nvidia dominates the global chips market for artificial intelligence (AI) with a fee that during the last three years has oscillated between 80 and 94%, according to Fourweekmba. Your leadership is supported by A very competitive hardware and a software ecosystem in which CUDA (Compute Unified Device Architecture) It has an essential role. This technology brings together the compiler and development tools used by programmers to develop their software for NVIDIA GPUs. Most of the artificial intelligence projects that are currently being developed are implemented on CUDA, and replace it with another option in the projects that are already underway it is a problem. Huawei, who aspires to an important portion From this market in China, it has Cann (Compute Architecture for Neural Networks), which is its alternative to CUDA. AND Moore Threads and Cambricon Technologies They have muse and neuware respectively. Even so, the competitors of Nvidia will cost them a lot to break the leadership of Cuda. Nvidia has distributed 94% of GPUs for market games During the second quarter of 2025, 11.6 million graphics cards for PC and 21.7 million processors for desktop computers have been distributed throughout the planet, according to the US consultant Jon Pedie Research. By themselves these figures do not tell us just anything, but they acquire the relevance they deserve if we consider that they indicate that the distribution of graphics cards has grown by 27% and that of CPUs 21.6% compared to the first quarter of 2025. Distributed units allow us to train a very precise idea about market behavior It is important that we do not overlook that these figures quantify the distributed units, and not the units sold. However, there is a direct correlation between them, so the distributed units allow us to form a very precise idea About market behavior. Anyway there is a fact that is even more shocking than all we have collected so far in this article: NVIDIA has distributed no less than 94% of GPUs for market games during the second quarter of 2025, again according to Jon Pedie Research. AMD has been forced to settle for 6% of the distributed units, and Intel does not even appear in the report of this consultant because its presence is anecdotal. So are things in the graphic hardware market for PC. One more note to conclude: the rebound of distributed units of graphics and processors for PC during the second quarter of 2025 against the first responds in all likelihood to the need for stores and users to supply before Tariffs approved by the US government They entered into force.

China showed the world an indecent amount of unpublished artillery. But the most advanced weapons remained hidden

by

Yesterday We enumerate And we draw the Route of China in the field of military arsenal during the parade that commemorated the 80th anniversary of the victory over Japan and the end of World War II. As We countthe message was quite clear and forceful, showing a part of the power achieved by the popular liberation army in its accelerated modernization. However, more than one AS was left in the sleeve. The hidden power. Some of those developments that have not already showed them here, others not so muchbut everyone has something in common: they are the most advanced weapons of the nation, hence their concealment in public light. Many of them remain in secret because they are still in the development phase, for their strategic sensitivity or because they cannot be exhibited in an event of these characteristics. What was seen in the Tiananmén Square was just a fraction of the real capacity of the Chinese Armed Forces, which in parallel develop disruptive technologies with deep implications for the future war. Aviation and “the” electromagnetic. We have treated it. China is testing site generation fighters, provisionally known as J-36 and J-50that after their inaugural flights they have continued in the trial phase, and whose level of sophistication remains under strict secrecy. Similarly, prototypes of Riel and coil cannonscapable of intercepting hypersonic and ballistic missiles at low cost, they are too limited in size and are restricted to large ships, making it impossible for their deployment in a terrestrial parade. The reusable space vehicle is also hidden, in Tests since 2020an analogous platform to the American X-37b which can remain months in orbit and meet classified military missions. Furtive hunt J36 What we did not see of naval power. Naval modernization has been central since the last parade of 2019, with the launch of the Fujian aircraft carriersthe construction of Future Type 004and the amphibious assault ships Type 075 and Type 076. To these is added the development of Strategic Submarine Type 096which will reinforce maritime nuclear deterrence in the next decade. None of these platforms can roll through Tiananmén, although some of its weapons and aircraft systems could be shown. Tests with an electromagnetic rail cannon Cyberdefense and Digital War. The PL considers cyberdefense one of the pillars of its national security. Since the creation in 2015 of the Strategic Support Force and, in 2024, of the new Cyberspace ForceChina has centralized intelligence, cyber attack operations and critical infrastructure defense. Although the parade It included winks To these “new forms of combat”, the authentic arsenal of cyber -cyberms and offensive capabilities, what is doubtful, will remain hidden, leaving in the shadow the true magnitude of Chinese digital operations. New furtive combat apparatus in the test phase in China AI and autonomous systems. Artificial intelligence integration is a strategic priority. The Pla Work in algorithms To process real -time combat data, optimize logistics and maintenance, and generate training scenarios. Attack and recognition drones as the GJ-11the Wing Loong and The Rainbow They already incorporate autonomous navigation, recognition of objectives and coordination with other platforms. Although some of these devices will be shown, their algorithmic “brain” will remain invisible to the public. Drone Rainbow prototype Nuclear deterrence. China deployed Intercontinental Balistic missiles and strategic bombers as a gesture of strength, but the true pillars of their nuclear deterrence did not come to light. The command, control and communications systems, designed to resist a first blow, the reinforced silos of the northwest, the vast network of underground tunnels known as known as The “Great Underground Wall” and nuclear submarines armed with ballistic missiles, both the TYPE-094A assets and The future Type-096. South China Sea, where elements of the Great Submarine Wall System are installed Early alert and antimisile defense. China currently has a strategic network that combines infrared alert satellites capable of detecting ballistic releases anywhere in the world and huge fixed matrix radars, capable of tracking missiles and furtive aircraft in full flight. These systems are vital for strategic defense And they have already overcome multiple interception tests since 2010, but their static and highly classified nature keeps them out of the parade. Fujian, the biggest war boat with China’s leading technology The “great underground wall.” As we said before, in parallel, China builds a underwater surveillance system With hydrophones, sensor nodes and autonomous vehicles to monitor enemy submarines in the Eastern and South China Sea. This framework, known as the “Great Underwater Wall”, is essential to guarantee the safety of its nuclear submarine fleet and reinforce its anti -submarine capacity. Its existence is intuited, but its location and operation remain in the strictest secret. And space. With more than 500 satellites military and double useChina is trying to achieve independence in navigation with Beidou, recognition capabilities with the Yaogan series and safe communications for command and control. It also develops antisatellite weapons, from direct ascent missiles tested in 2007 even orbital proximity maneuvers and possible directed energy weapons. None of these systems appeared in the parade, but represent a key vector of their “computerized” war strategy. The industrial force. It We comment yesterday. China’s greatest hidden trick is not only technological but industrial. The ability to produce in its own territory from rifles to aircraft carriers, through reaction engines and hypersonic missiles, ensures independenceresilience and speed of production. The Military-Civil Fusion Strategy allows civil advances in defense, as occurs in aeronautical engines, where the experience of the CJ-1000A Commercial feeds the development of The WS-10 and WS-15 that drive the J-20 furtive fighters. In short, the parade showed the world a Power showcasebut the most lethal and transformer of the Chinese armed forces was hidden. Under the surface, in tunnels, in satellites, in monitored seas and in high -tech factories, there is a framework of capacities that seeks to redefine global military balance in the next decades.

China has just told the world the place it wants to occupy. And he has done it with a parade of weapons that seem like science fiction

by

During September 3, Beijing has become the stage of one of the Chinese military parades more elaborate that are remembered, commemorating the 80th anniversary of the end of World War II. An event that China has used to Promote nationalism through a parade where to show the world the place he wants to occupy. And according to the artillery that has seen the lightThere are no limits. Artillery as support. As we said, the imposing military parade in Beijing was conceived as An unequivocal message: Xi Jinping’s vision of a new world order with China in the center has a warlike vanguard apparatus that begins to be at the height, and even ahead, of its rivals. Among the protagonists highlighted the new intercontinental ballistic missile DF-61successor of DF-41together with missiles with hypersonic plankers capable of exceeding the speed of sound five times and complicating any antimile defense. The demonstration included a broad Drones repertoire (aerial, terrestrial and submarines) with functions ranging from direct combat to logistics, some designed to act as “faithful squires” of Chinese furtive fighters, consolidating the EPL’s commitment to the Autonomous War. DF-61 Directed energy weapons. Beyond the missiles, the true revolution was on the exhibition of Laser and energy weapons directed, in naval and land versions, capable of neutralizing sensory and drones enemy at ridiculous costs compared to conventional ammunition. If these systems are deployed in number, such as They hinted Official sources could suppose an unprecedented challenge for any force that tries to stop Chinese military movements in their region of influence. This technological turn, supported by an enormous industrial capacity, points to a strategy where the quantity and sophistication They combine to cement China’s strategic ascent. Set of laser weapons during the military parade Two versions. They appeared Two laser systems Air defense: a large one, intended for its installation in warships, and another mounted on an eight -wheeled vehicle, capable of hosting the necessary electrical power to overcome the limitations of previous versions. These systems, which do not depend on kinetic projectiles but on Electromagnetic energy To destroy objectives through heat, electrical interference or sensor blindness, they mark a turning point in the anti -aircraft and anti -anton defense. In front of them, high -power microwave systems (also in development) offer the ability to neutralize whole swarms of drones with simultaneous bursts. The logistics and economic advantage is evident: each shot costs a fraction of a missile and does not require transporting heavy ammunition, only energy. Submarine drone AJX002 The debut of underwater drones. China also showed for the first time Two submarine vehicles not large -sized (Xluuv), consolidating their leadership in a field where at least five different programs in the test phase already operate. One of the exhibited models, identified as AJX002measures between 18 and 20 meters long with a reduced diameter of up to 1.5 meters, while the second shares length but is considerably wider, between 2 and 3 meters, and carries two masts. Although their specific missions have not been revealed, analysts consider carry torpedoes or mineseither fulfill recognition functions in prolonged and high autonomy operations. With this presentation, the Chinese Navy confirms its intention to integrate underwater platforms Autonomous on a large scaleexpanding the unmanned war options in a domain traditionally reserved for conventional submarines. Some of the hypersonic missiles shown The YJ-17: hypersonic and “nuclear.” Among the most strategic revelations The YJ-17 wasa missile that combines the naval denomination of the YJ family with the technological inheritance of DF-17the first medium -range ballistic missile with a hypersonic planner (HGV) developed by China. If the DF-17 already demonstrated extreme precision in tests (capable of impacting a few meters from its target after performing evasive maneuvers), the YJ-17 supposes the adaptation of that system For vertical pitchers of warships. Although it is believed that it can carry conventional eyelets, its nuclear capacity cannot be ruled out, which reinforces its deterrent value. Non -manned wing aircraft of the Plaaf. Two different configurations were seen but no designation details have been provided The industrial muscle as an advantage. No doubt, the parade was also proof of the volume of production that China can sustain. According to analysts Like Malcolm Davisthe country demonstrates the ability to develop, manufacture and deploy faster and higher advanced systems than the West. In other words: it is a reminder that, while in World War II the American industry inclined the global balance, today is Beijing who You can manufacture in mass Military teams with efficiency that Washington can hardly match. The CSIS data They confirm this trend: Chinese military expenditure has multiplied by thirteen in 30 years and already exceeds its immediate neighbors, quintupllica that of Japan and septuming that of South Korea. Anti-Enlambre Training (MENGSHI Laser “OW5-A10”, “PLB-625” cannon of 6 x 25 mm, 30 mm cannon, “Mini dome CUAV FK-3000”, Laser HMV3 “OW5-A50”) The naval dimension. Already We count yesterday. The biggest difference with the United States is perceived in the sea: by 2030, the Chinese Navy could have a 48% more ships of war that the American, which revives the historical maxim that the largest fleet usually imposes itself. While in the West it is confident that technological superiority, such as drone swarms with artificial intelligence, maintain balance, the parade showed that China already has Advanced autonomous systems in active duty and in operational quantities. In addition, the introduction of laser defenses against drones and missiles reinforces Beijing’s narrative about an “intelligent war”, where autonomy and systems network dominate the battlefield. JY-17 The Arsenal per sea. The YJ-17 did not appear alone: ​​it was accompanied by anti-man- YJ-15, YJ-19 and YJ-20all conceived to be deployed from the largest surface fleet in the world, composed of destroyers and frigates with vertical pitchers. Here the strategic message seems clear: the American aircraft carriers, the cornerstone of Washington’s naval power in the Pacific, could be vulnerable at any point in the region before a coordinated rain Hypersonic missiles and cruise released from multiple platforms.

Spain has been a world reference in high speed. And the doubt is whether we are dying of success

by

Saturation. That is, according to the Government, the reason why Spanish high speed does not stop accumulating delays and breakdowns. At least, that’s what is suggested. The increase in frequencies, new competitors and the same ways. Those are, for the government, the reason why Spanish trains have been forgetting a year. 289 trains. In the 90s, “6 trains a day, by direction, today through the Torrejón de Velasco point of the Madrid-Sevilla high speed, 289 trains circulated.” With these words Óscar Puente, Minister of Transportationof those who point out that in the 90s there were no problems of delays that today exist in the high railway speed of our country. “If there was an incidence in the infrastructure or the train, the impact was minimal. The time it took another to pass allowed to solve the problem. Today when there is an incidence you have 25 trains in both ways in a radius of one hour. Therefore the effects are greater. The controversy. The bridge response tweet comes to an interpellation in which a user indicated that In the 90s you could take a train without fear of delays. The answer also coincides with a new fault in the high -speed line of the Andalusian corridor where 261 passengers had to be evicted from a train because a car caught fire Last Saturday, August 30. This caused delays throughout the afternoon. However, the fire was not the only cause of delays. That same morninga breakdown in the infrastructure was also causing delays in the trains because it was showing a false obstacle sign on the road. Although before restoring the service it was already known that this obstacle did not exist, the machinists had to stop to comply with the protocol. A summer to forget in Andalusia. The events of September 30 have been the last of this summer but, much less, the only ones. In early July, A train was stopped 13 hours On the roads and their passengers they did not receive assistance from emergency services throughout the night. Days later, another problem with A catenary in Toledo It caused significant delays in the same high -speed line. He even had to stop passing through one of the tunnels of the Malaga line by leaks in one of the facilitieswhat had caused detachments. And Adif? The first of those incidents It seemed to come from an ouigo train which was disconnected from some security systems. This caused the chain stop of four other trains that circulated in the same area. One of those operated by Renfe, overloaded by the stop, ended up suffering a small fire of his systems, being completely arrested. The problem affected More than 16,000 passengers and From Adif they pointed to the French company as the cause of the problem. Ouigo, meanwhile, returned the accusation saying that Adif did not maintain the facilities correctly. A few days later (and after the adif notice that the critical points of the infrastructure was going to review) that Second problem in La Sagra (Toledo) who stopped the trains again. More traffic volume … The truth is that the volume of traffic in the high Spanish speed has shot in recent years. To give only one example, the day of the fault that left a train for 13 hours 30 trains between Madrid and Andalusia had to circulate. Yes it is true that 30 years ago, that volume of traffic was unthinkable. To the traffic of Renfe we ​​must add the entrance of Ouigo and Iryo into the Spanish railways which, without a doubt, has stressed the tracks. If there are more trains, there are more possibilities of suffering a delay but there are also more possibilities that such delay affects a greater number of trains. To get an idea, in 1992 (with the inauguration of the first high -speed line) 1.3 million passengers traveled between Madrid and Seville. In 2024, that figure was 5 million passengers. Another 5 million passengers were recorded in the corridor to Malaga. And throughout Spain almost 40 million passengers moved in this type of trains, According to CNMC data. … but an insufficient investment. In ELECONOMIST They point out that Adif’s investment in infrastructure is greater than ever. In 2025 just over 681 million euros will be allocated while in 2015 it was 465.5 million euros. However, they point out that taking into account their heritage, Adifs spends 16% less than a decade ago. Keep in mind that in that decade, in addition, the Spanish railways have gone from some 31 million passengers To touch the 40 million and the number of trains has multiplied with the entrance of Ouigo and Iroyo. Everything indicates that the investment in the facilities is insufficient and, above all, it is late if we take into account the increase in the number of travelers. In 2021 investments were guaranteed until 2025 worth 21,000 million euros in Adif But this game It is not dedicated entirely to maintenance of the tracks. That is, it seems that “emergency” maintenance is being carried out in too stressed lines for the expense that had been made in them.

Wetaca doubles benefits thanks to the classic digital world trick: hooking to a subscription

by

602,000 euros of net profit in 2024, twice as much as the previous year. Wetaca has achieved what seemed impossible in the competitive world of food at home: grow in sales (23%) and improve margins at the same time, according to their 2024 accounts that he collects Five days. The turn. The company, founded by former Masterchef Efrén Álvarez consistent, has ceased to be a company that sells Tápers to become one that you subscribe. The automatic subscription model, launched in 2021generate weekly orders that are sent unless the client modifies or cancels them. You no longer have to remember to ask: the menus arrive alone. This apparently subtle change has changed the business. The recurrence has become the Holy Grail of Wetaca, which has invested more than 1.1 million euros in marketing to capture subscribers, twice as much as in 2023. In perspective. The prepared food sector lives a paradox: Dark Kitchens They left their best moment behind and the aggregators of Delivery They have a complicated profitability, but Wetaca is thriving with a model that seemed to have a difficult fit with the current offer. Centralized cuisine in Villaverde. Tápers that are sent cold. Menus that last a week in the fridge. Model that asks for a conscious and planned purchase, not impulsive. The difference is in the economic equation. Without RIDERS No commissions to platforms, without the pressure of delivering in half an hour. Only efficient production and customers that automatically repeat each week. And now what. With 94 employees and a debt of 5.2 million (1.5 in the short term), Wetaca will need subscriptions to continue flowing. The commitment to new machinery seeks precisely that: producing more maintaining the margins that have cost them so much to achieve. Between bambalins. The founders Álvarez and Casal maintain 71% of the company, while Cabiedes & Partners control almost 20%. This concentrated shareholding structure has allowed them to bet on the long term instead of pursuing growth at any price, the curse of so many delivery startups. The subscription model not only allows them to sell more: that model is a prediction machine demand, optimize production and reduce waste. When you know how many tápers you will cook every week, everything becomes more efficient.
