YouTube is ready to launch the largest video reconstruction project in history. And yes, it will use AI

by

YouTube was born in 2005 and, since then, it has become the largest audiovisual archive in recent history. For years, millions of users uploaded videos in 240p or 480p because that was what the cameras, connections and devices of the moment allowed. This material does not lose value because it has low resolution: there are extraordinary pieces that continue to be a reference. But today the screens are better, the sound matters more and that difference is noticeable. So now comes an attempt to update that experience without erasing the past. An ocean of videos. The YouTube catalog is not large: it is huge. The figures published by electroiq put the total at around 4.3 billion videos in 2025, after a stage in which the Shorts format It pushed the increases to levels never seen before. About 800 million were added in 2023 alone. That momentum has tempered, in part because of controls on repetitive content and a lower craze for short clips, but the trend remains. If the current pace continues, the service could surpass 10 billion videos before 2030. YouTube begins to “reconstruct” its videos. YouTube has announced that will begin to automatically improve videos uploaded in resolutions between 240p and 720p, raising them to HD quality using artificial intelligence. The process does not delete the original files or modify the base video: it is an alternative version visible under the “super resolution” label. Creators will be able to decide if they want it to be applied and viewers will retain the option to view the content in its original resolution. It is a measure that seeks to modernize the archive without altering its authenticity. Lens: 4K. The roadmap is clear. After starting with videos below 1080p, YouTube wants automatic enhancement also reach 4K resolutions “in the short term,” according to its announcement. To support that jump, heavier uploads are already being tested with some creators and thumbnails will also be able to reach 4K, thanks to the extension of the file limit from 2 MB to 50 MB. Everything points to an attempt by the platform to ensure that both the content and its presentation are at the level of current panels. The audio also goes up a notch. The modernization of the catalog does not stop at the visual. YouTube has also introduced automatic audio enhancements that adjust the mix and maintain a more consistent volume between different scenes. These automatic improvements are grouped under the “Stable volume“, which the viewer can activate or deactivate according to their preference. With this, the company seeks to prevent sound jumps from breaking the experience, something common in old videos or recordings with basic equipment. It will not be for all videos. YouTube clarifies that these improvements will not be applied indiscriminately. They will only affect videos uploaded in low resolution that have not been previously remastered to 1080p or higher. Additionally, as we already mentioned, creators can decide from YouTube Studio whether they want the platform to apply visual or audio enhancements to their future uploads. It is a measure that seeks to avoid unwanted distortions and give room to those who prefer to keep their content exactly as it was published. If these enhancements are disabled for the channel, viewers may not be able to use features such as “Stable volume” or “Super resolution” on that content. Upscaling no longer lives on your TV. Many televisions include their own systems to improve the image, but YouTube’s approach is different. Instead of applying upscaling on the device, the platform does it in the cloud, allowing it to process millions of videos consistently without depending on the user’s hardware. Additionally, the viewer can choose between the original playback or the enhanced version from the quality menu, with an option visible and explicit in the interface. Catalog, discovery, legacy. For creators, this update has an immediate benefit: they don’t need to re-upload old videos to make them look better on current screens. The file remains intact and the enhancement is applied as an additional layer, respecting the original. This can help valuable pieces from years ago gain presence, without altering their essence. The viewer, for their part, receives a more homogeneous experience and the possibility of choosing how to view each content.

Renfe has its AVRIL trains ready to put them back on the tracks. You just have to show that they don’t split

by

It seems that the soap opera of Renfe’s AVRIL trains is beginning to see the light at the end of the tunnel. The company has already received the completely repaired trains from Talgo, according to The Economistwho claim that the company has confirmed this point to them. The first question is what will be the new destination of these trains. The second is whether they will pass the litmus test: proving that they do not split. Back. Renfe already has the S106 trains affected by the cracks suffered in the Madrid-Barcelona corridor while providing AVLO service. That is what the company itself has confirmed to us, which, when asked by Xataka has confirmed that the replacement of the bogies has now “been successfully completed”. The trains have returned three months after being sent for repairs to the railway company’s facilities. They have done so after having completely replaced the affected bogies. Instead of being repaired, they have been completely changed to avoid greater evils. What happened? At the end of July, Renfe began to receive signals that something was wrong with its AVRIL trains that provided the AVLO service (Renfe’s low cost line) on the Madrid-Barcelona route. Those signs were, directly, cracks in trains. Although first there was talk of one train, we finally know that there were five that ended up affected by cracks of different magnitudes. After a tug of war between The Economist (which advanced the news) and the company itselfRenfe ended up suspending the sale of AVLO tickets on the Madrid-Barcelona route and ended up redistributing the AVE service to customers. Now the company recovers those affected trains but it does not seem that Madrid-Barcelona will be their destination. Whose fault is it? It is one of the great unknowns. Renfe has pointed out Talgo as the culprit of the cracks, reminding him that the trains are under warranty and that, therefore, they were not going to pay for the repairs. Talgo, for its part, blames Adifensuring that the maintenance of the line is insufficient and that this has caused excessive vibrations that have led to the famous cracks. Everything indicates that the problem is in the section between Madrid and Calatayud. In fact, the company even considered that it would continue operating with its AVLO service in the corridor but at a reduced speed which, it is assumed, did not generate the vibrations and therefore should not have an impact on structural damage to the train. Ultimately, this option was discarded. Fire test. The return of the affected AVRIL trains is a litmus test for Renfe… but above all for Talgo. And it is that Renfe has already been looking for trains in Germany to look for an alternative to the S106, known as AVRIL, which only Talgo manufactures. Giving a good image with a unique train in the world is essential to a company that is in financial trouble. The S106 trains were to be a leap forward for the company. They are the only ones who, given the railway peculiarities of Spainthey can “jump” from Iberian gauge to international gauge. For Renfe they are key because this allows them to position themselves ahead of Ouigo and Iryo facing a future opening to competition in the Galician corridor. However, the S106 have arrived late and They have garnered numerous bad reviews. And where are they going? It is another of the doubts that remain to be cleared up. According to Alberto Puivecinoresponsible for infrastructure and mobility at CCOO in Catalonia, it is possible that these trains will be used for AVANT (medium distance high speed) services in the region. A line that joins Lleida, Tarragona, Barcelona, ​​Girona and Figueres. The information was made public after a meeting between CCOO and the Generalitat of Catalonia. In Xataka We have asked Renfe in this regard but they assure that “the service that the currently immobilized units 106 will provide has not yet been determined. In any case, wherever they are finally going to operate they will do so with full safety guarantees.” For now, the fate of these units remains to be revealed. What we do know is that it is a litmus test for Talgo that must demonstrate that its S106 trains are once again reliable and, above all, are safe enough.

is called F110 and is ready for any war

by

It has not been any summer for Spain in defense. In August He knew he resigned to around 50 F-35 that the Ministry of Defense had “applauded” with the United States. It was also said that the idea was to bet on European investment In defense. The truth is that Spain has almost ready that will be a source of pride of its Navy. It is called F110 and it is a portent. A new generation. The Bonifaz frigate launchfirst of the Class F110in the shipyards of Navantia in Ferrol, it has marked a milestone for the Spanish Navy and for the country’s own naval industry. With a degree of progress greater than 70% and delivery planned in 2028, the ship opens a series of five units conceived to replace the VETERANAS F80 SANTA MARÍAin turn heirs of American architecture Oliver Hazard Perry of the eighties. F110 represents not only a generational relief, but also a strategic commitment to a versatile design and Highly automatedconceived from the beginning to grow and adapt to new demands. The construction of the other units already advances: the F112 has the keel placed since April 2025 and the blocks of the following frigates are mounted in parallel in the Ferrolan workshops. A flexible ship. From its conception, the F110 was designed as a frigate Antisubmarine war First order, with a technological package that places it among the most advanced in Europe in this field. Incorporates a helmet sonar combined with the powerful Captas-4 Compact Towed of Thales, capable of detecting submarines at a great distance and precisely, in addition to a NH90 helicopter either SH-60 Dedicated to this task, accompanied by a second hangar thought for drones or unmanned systems. All this makes the new class a multiplier of underwater forces, an increasingly relevant field in a context in which Russian underwater activity He has recovered prominence In the North Atlantic. But F110 does not give up other dimensions: it is also a Multipurpose ship with large areas of mission and space to accommodate future teams, which makes it an open platform to technological evolution. The bonifaz frigate launch in Ferrol on September 11 The strategic dimension. One of the most distinctive elements of design is its huge mast, which houses the AN/SPy-7 radar (v) 2 From Lockheed Martin, derived from the long -range discrimination system installed in Alaska. Its high position gives you an exceptional field of vision and makes it a sensor capable of continuing even objects in space. Although the frigate does not carry weapons capable of Intercept ballistic missiles In full flight, your data can feed allied networks, reinforcing NATO antimisile defense and complementing the capacities of Spanish F100, optimized for anti -aircraft war. The integration of this radar with the management system of National Scomba Combat It symbolizes technological cooperation with the United States without giving up its own industrial control, a balance that enhances the strategic autonomy of the Navy. Balanced armament. In terms of aerial defense, F110 surprises with a relatively moderate arsenal compared to its predecessors: two MK 41 modules that house up to 64 Essm Block 2 missileseffective against short and medium range threats. It is a configuration that guarantees local protection and some area coverage, although the door to be integrated into the future Standard family missiles is open, which would expand the defensive scope. In the surface fight, the ship combines the missile Naval Strike Missile of Kongsberg, with a discreet but precise and difficult scope to detect, with a 127 mm cannon in bow, two of 30 mm and light machine guns. To this are added Electronic War Systemscountermeasures, launch of fast boats and a set of sensors that reinforce their role as an escort and as a presence ship in NATO missions or the European Union. International comparisonss. The F110 approach is part of a global trend of Polivalent frigates with anti -submarine emphasis, similar to that of the British Type 26also chosen By Australia, Canada and Norwayoa la American constellationbased on Italian design FREMM. Paradoxically, the US Navy rejected the Spanish proposal of a F100 frigate, opting for the FREMM, and today Pay the consequences with a program that accumulates delays, overweight and cost overruns. In contrast, the Spanish calendar progress promptlywith the bonifaz even advanced to the expected. This industrial discipline reinforces the attractiveness of F110 as a possible export product in an international market that demands versatile, modern and controlled costs. Multiple relevance. If you want also, the Incorporation of the ship War will consolidate the transition from the Navy to a fleet of complementary frigates: The F100 as specialists in area air defense and the F110 as submarine hunters with a sufficient balance in surface and air capabilities. Together, they will offer Spain a strategic combination of media adapted to the challenges of the Atlantic and Mediterranean, while projecting full interoperability with NATO allies. Thus, F110 is not just a new ship: it is the materialization of a national strategy that combines its own technology with international integration, a bridge between tradition and future that, unlike other international programs (Many in trouble), seems to advance with a firm step and could place Navantia in the world showcase as a reference construction company.

The largest nuclear fusion project on the planet has survived the setbacks. This is the date on which Iter should be ready

by

2024 was a difficult year for ITER (International Thermonuclear Experctor reactor). This experimental reactor of nuclear fusion It is being built in the French town of Cadarache by an international consortium Led by the European Union. Although it was conceived in 2006 and the project was officially launched in 2007, the beginning of the assembly of this titanic machine did not start until 2020. The initial itinerary Proposed by Eurofusion, which is the institution that is responsible for promoting and supporting the scientific research necessary to bring to fruition the European Nuclear Fusion Plan, established that in 2025 the assembly of this machine would end. However, that same year another crucial milestone would arrive: the first tests with plasma would start. Three years later, in 2028, Iter engineers would begin the low power with hydrogen and helium, and in 2032 the first high -power experiments would arrive with these two gases. Finally, in 2035, Iter would be able to undertake high power tests with deuterium and tritium. And in 2040 this experimental reactor would demonstrate the energy profitability of nuclear fusion. Finally this will not happen like this. In 2022 the French Nuclear Safety Authority (ASN) identified several irregularities of a strictly technical nature in Vacuum Chamber sectorswhich caused the Iter organization to react as it should do so: constituting a working group to address the complementary requests of the ASN and advance with the reactor assembly Tokamak. Iter’s technical challenges are unpublished Assembling a machine as complex as it is it is not easy. The vacuum chamber weighs 8,000 tons, is made of stainless steel and boron and must remain hermetically sealed. Its assembly has forced engineers to deal with extraordinarily strict local tolerances of 0.1%, and, in addition, the camera has a very complicated shape and uses plates with thicknesses up to 60 mm. To solve the assembly the technicians have had to resort to state -of -the -art technologies, such as the Electron Beam Weldingwhich is welding using an electron beam, or The design of AI models specifically conceived to identify defects in the welds of the camera. The Covid-19 Pandemia that raised very crudely during the 2020s and 2021, and, on the other hand, the technical challenges derived from the completely unpublished nature of much of the components that need to be tuning so that Iter arrives in fruition have caused that The main milestones of this project are delayed. Nevertheless, The current updated itinerary proposes several important dates that interest us know. In 2039 Iter will be able to undertake high power tests with deuterium and tritium In 2034 the first experiments will be carried out in the reactor; In 2036 the magnetic system responsible for confinement of plasma to maximum power will be tested; And finally, in 2039 Iter will be able to undertake high power tests with deuterium and tritium. Initially this last milestone was going to arrive in 2035. Whatever it is during the last year the Iter assembly has advanced at a good pace. In the cover image of this article we can see two of the titanic sectors of the vacuum chamber, although, in my opinion, one of The milestones that this project has achieved This year It was consolidated in May. The superconductor magnets placed on the outside of the vacuum chamber of this nuclear fusion reactor have the responsibility of generating the magnetic field necessary to confine plasma inside. They are also responsible for controlling and stabilizing it. These magnets weigh 10,000 tons and are manufactured in an alloy of niobio and tin, or niobio and titanium, which acquires the superconductivity when cools with a supercritical helium until reaching a temperature of -269 ºC. This requirement justifies the need to put a powerful cooling system like the one that has devised Europe for Iter. In the construction of this experimental nuclear fusion reactor, the US, Russia, China, India, South Korea, Japan and the United Kingdom, but the cryogenization plant have been commissioned by Fusion for Energy (F4E), the organization of the European Union that coordinates the contribution of Europe to the development of Iter, the French company Air Liquide and technical integrated technicians in the Iter structure. Superconductor magnets acquire superconductivity when they reach a temperature of -269 ºC This extreme refrigeration installation will be responsible for supplying liquid helium to 4.5 Kelvin (-269 ° C) to superconductor magnets and criobombs, and also gaseous helium at 80 Kelvin (-193 ºC) to thermal shields. Creobombs are empty ultraalt devices that are responsible for eliminating gases inside the vacuum chamber. To do it They must work at an extremely low temperature. And, on the other hand, the thermal shields are responsible for protecting some critical elements of the reactor, such as superconductor magnets, the heat that emits the confined plasma inside the vacuum chamber. Iter’s cryogenic plant has an area similar to that of a football field (just over 7,100 m²) and contains several 26 -meter high storage tanks. These figures help us intuit how enormous this critical installation is. As we have just verified, without it the nuclear fusion would be absolutely impossible. This Grigory Kouzmenko statementF4E manager, invites us to tie Iter’s future with a reasonable optimism: “We have entered the most exciting phase of the project, in which all the efforts of previous years finally are specified and we can benefit from the collaboration based on the confidence between all the parties.” Image | Fusion for Energy More information | ITER In Xataka | From today Spain has the key to nuclear fusion: Granada’s particle accelerator is already a reality

LG has created a “invisible” aspirator robot. It is saved under the sink, it makes little noise and keeps the mopa always ready

by

Aspiring robots have become regular household partners. They have gone from being a technological whim to a practical tool that avoids spending hours to cleaning. However, as we get used to them, we have also begun to demand more: It is not enough that they aspire wellwe want them to do it without interrupting our routine, without occupying space or generating noise. The real comfort is that they work without us just perceiving them. In this scenario it appears LG’s last proposalthought precisely to make that jump. A model that not only seeks to fulfill the task of cleaning, but to do it in the most discreet way possible. The concept is not to add more buttons or striking functions, but in reducing its presence at home, to the point of becoming almost invisible to the user’s eyes. Technology that cleans and disappears from the visual map The South Korean firm will present at the IFA 2025 fair an aspirator robot that moves away from the conventional. Instead of settling in a visible base in the middle of the room, Your station hides under the sinkoccupying a space so far wasted in many kitchens. With a design designed to go unnoticed, it is integrated into the domestic environment without altering aesthetics or requiring additional surfaces. We are facing a proposal that not only seeks discretion, also comfort. The station door opens and closes automatically so that the robot can enter and leave without user intervention. In this way, the cleaning experience becomes completely hands -free, in a line other than that of other vacuum cleaners that continue to depend on voluminous stations in sight. Beyond its hidden location, the robot incorporates technical improvements designed to optimize cleaning. According to LG information, it integrates an artificial intelligence chip that allows you to recognize furniture, objects and areas with dirt, which translates into a more precise navigation and adapted to the environment. It also has a system that detects carpets and automatically orders return to the station to detach the mopa, avoiding unwanted spots on textile surfaces. The station, with discreet appearance, also plays an active role in maintenance. Not only loads the device, it also sterilizes the mop with hot water and steam after each use, reducing odors and guaranteeing constant hygiene. With this, the South Korean company seeks that the user does not have to perform additional tasks and that the feeling of cleaning is maintained at all times. Although the proposal is attractive, there are still important questions. LG has not revealed the commercial name of the model, or its price, nor the availability date in Spain. Nor has it detailed essential technical aspects, such as suction capacity or battery autonomy, data that usually make a difference when choosing between one vacuum or another. The South Korean company has preferred to reserve that information for later, within the framework of the IFA 2025 fair, which is held in Berlin from September 5 to 9. Until then, what is known is rather a declaration of intentions: an approach oriented to practicality and discretion, with the challenge of demonstrating in practice that may be up to its rivals. LG’s challenge is not less, because it enters In a field with consolidated actors. Brands like Irobot, with the Roba Max 705They have opted to facilitate cleaning in households with pets. Roborock, with Saros Z70has taken an innovative step by integrating a robotic arm that expands the extent of cleaning. And dreame me, with the Aqua10 Ultra Roller Completeit focuses on solving one of the usual weaknesses of these devices: the maintenance of the mop. The commitment to a robot that practically disappears seeks to differentiate LG in this competitive scenario. It is not just about offering an effective product, but about convincing users that discreet integration and minimum maintenance are added values ​​in front of a very varied catalog. The LG approach fits with a clear trend: we want technology to do its job without interrupting us. Aspiring robots had already earned a place at home, but this movement points to a new level of integration. A device that automatically cleanshe stays ready by himself and is barely seen. It remains to be seen if the real performance accompanies the promise. Images | LG In Xataka | DREame H15 Mix, Analysis: If I could only buy a vacuum cleaner to clean everything, it would be this

Nvidia is ready for the chip for the need to survive in China. Who is not ready to let him sell is the US government

by

The journey in China of the Nvidia GPU for artificial intelligence (AI) H20 He has been full of ups and downs. Since this chip reached the Chinese market in mid -2024 its sales 50% quarter to quarter grewwhich positioned it as The most successful Nvidia product of recent years. However, this era of bonanza lasted little. And it is that in the middle of last April the US Department of Commerce decided impose export restrictions To China of the H20 GPU. After several weeks of negotiations with the US government Nvidia got the export license that he needed to sell his GPU for the H20 in China, but the joy lasted little. And it is that the Chinese government has vetoed this chip. And he has done so that the administration of the cyberspace of China, which is the main Internet regulatory body in this country, is thoroughly investigating this GPU because it suspects that it could incorporate a rear door of difficult location by Chinese experts. Nvidia engineers have been working on a new GPU for several months for expressly designed for the Chinese market. It will be called B30A And on his shoulders he will rest, neither more nor less, the future of the company led by Jensen Huang in China. This chip must necessarily meet two conditions. On the one hand it has to be more powerful than the GPU H20, and, in addition, it must satisfy the restrictions imposed by the US Department of Commerce. Otherwise Nvidia will not get the export license you need to be able to sell this chip in this Asian country. The future of the B30A GPU in China right now is uncertain Chinese companies that are dedicated to the development of large AI models are trapped. On the one hand they are being forced to deal with the export restrictions of the GPU imposed by the US government. And, in addition, they are subject to their own dependence on American technology. A priori the optimal solution for them would be to stop buying Nvidia and other US companies their chips for AI, and getting “comparable” GPUs proposed by Huawei, Change either Moore Threadsamong other Chinese companies. Jensen Huang has just recognized that his next GPU will take to arrive in the country led by Xi Jinping However, as explained in your article to Foreign Policy The American analyst Kyle Chan, the scenario they face is more complicated than it seems. And it is that abandoning Nvidia in practice is very difficult. According to ChanTencent, Bytedance, Alibaba and other Chinese companies They prefer GPUs for Nvidia Because its performance is greater, especially when facing the training processes of their AI models. However, they especially opt for the chips of this American company thanks to CUDA (Compute Unified Device Architecture). Most of the AI ​​projects that are currently being developed are implemented on CUDA. This technology brings together the compiler and development tools used by programmers to develop their software for NVIDIA GPUs, 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, but for the moment CUDA dominates the market. In these circumstances, the B30A chip that is putting to point Nvidia has all the meaning of the world. Presumably It will be half powerful that the most advanced GPU this company currently has, The B300 chipbut, even so, it is reasonable to assume that will overcome performance of all the chips for the developed in China, especially when facing the training processes of the AI ​​models. This is the best asset that Nvidia has, but Jensen Huang has just recognized that its next GPU will take to arrive in the country led by Xi Jinping. And it will not be because it is not ready. It will be because the US Trade Department will take long to give it approval, if it finally gives it. What is happening to Nvidia in China is a full -fledged soap opera.

China has no rival in batteries and solar panels. It is already ready to also destroy Western pharmacists

by

China’s quota in the world photovoltaic cell market Broken 80%and for the moment only India seems to have the ability to disturb him in the long term. Its manufacturing capacity is 17 times greater than the rest of the planet togetherwhich has encouraged the Chinese administration to support the manufacture of More than 1,000 GW in N -type cell capacity As the other countries fulfill their net emission commitments. On the other hand, China is also a world leader in The production of lithium batteries. If we stick to electric cars the country led by Xi Jinping Fabrica 57% of batteries that these vehicles use. Catl and Byd are the largest lithium batteries manufacturers on the planet with A market share in 2023 34% and 16% respectively. Its absolute leadership in these two sectors is the result of a strategy that prioritizes investment in R&D and large -scale production to shoot competitiveness. Now Chinese biotechnological companies plan to apply this successful formula to medicines. China has the ability to drastically reduce the cost of medical care “We can reduce the costs of medical care and benefit more people through technological innovation and the improvement of efficiency (…) the recent achievements of China in the field of biotechnology show that it is possible to do it,” says Da Liuthe CR-CP Managing Director Life Science Fund, a risk capital investment group created by the Chinese state and the Thai chain Pokphand Group conglomerate with the purpose of investing in biotechnology companies. “We can reduce medical care costs and benefit more people through technological innovation and efficiency improvement” Chinese pharmaceuticals and biotechnology are living a “Deepseek”. This means simply that the medications they develop are every time most demanded by multinational corporations. What the latter pursue is to obtain the necessary licenses to market, produce or distribute the medications developed in China without elaborating them from scratch. Just three weeks ago the American investment bank Jefferies published a report in which he argues that Chinese companies and assets are extraordinarily competitive thanks to “their efficiency in costs, their small deadlines and the quality of the resulting product.” Interestingly, in seven of the ten main agreements carried out by the global pharmaceutical industry during the first semester of 2025, Chinese licenses were involved, According to the Pharmcube consultant. The success of the Chinese pharmaceutical industry is supported by a strategy very similar to that which has led this Asian country to lead the markets of solar panels and lithium batteries. However, China does not have it as easy as it seems. And it is that the geopolitical tensions that mainly support the countries led by Donald Trump and Xi Jinping are very difficult for Chinese biotechnological companies their international expansion through mergers with foreign companies. According to Liu What they need to transform into great multinational actors in the pharmaceutical industry is to achieve a dominant position in at least one or two fields of biotechnology.

His bet is called KF-21, and is almost ready for real action

by

The KF-21 has not been designed to impress Washington, or to compete with the F-35 in rankiness. It has been designed for something simpler and more ambitious at the same time: that South Korea does not depend on anyone when you need a combat plane. The country is called Boramae, Hugon Hunterand want it to be the axis of your Air defense until 2032. It is not just a new generation hunting: it is a symbol. And everything indicates that it will also be a notice for its neighbors. When South Korea wanted to access F-35 technologies to integrate them into their future hunt, he ran into a resounding negative. The United States rejected Transfer key systems such as Radar Aesa, the electrooptic aiming system (Eots), IRS and the radiofrequency disturbance of electronic warfare. That episode was decisive. Seoul assumed that, if I wanted to have control, I would have to build from scratch. Thus was born the KF-21. With him, Korea does not break with his western partners, but marks a clear line: there can be no real sovereignty if the most sensitive technology continues to depend on third parties. The South Korean jump towards autonomy in defense For Seoul, the KF-21 not only responds to a desire for industrial independence. It also responds to a strategic need. Tensions with North Korea are cyclical, but constant. China continues to rearm. And Japan already works with the United Kingdom and Italy at the GCAPthe future sixth generation hunting that should fly around 2035. South Korea does not want to be left behind. According to DAPA, the agency in charge of the projectthe KF-21 will first replace the F-4 and F-5, and then apart from the F-16. Having your own plane is defense, but also positioning. According to the governmentSouth Korea became the eighth country to get a supersonic hunt for its own development to carry out a test flight. The first prototype of the KF-21 was presented in April 2021. Three months later, On July 19, 2022, he first took off from the Sacheon base. Since then, the six planned prototypes are already flying and have exceeded milestones such as the first supersonic flight (January 2023) and the first real tests with meteor missiles (May 8, 2024) and Iris-T (May 17, 2024), according to Dapa and Diehl Defense. Deliveries to the Air Force will begin in 2026. One of the KF-21 keys is what it has inside. The aesa radar that equips is not imported: It has been developed in Korea by Hanwha Systems and the Defense Development Agency. The same goes for much of the plane, mission systems and sensors. The objective, According to Kaiis to reach a rate of 65% nationalization In serial production. The engine may not be yours yet, but what is seen in the cabin and radar is. Developing KF-21 has not been cheap. According to Dapa figuresthe initial development budget was set at 8.8 billion Wones, which is equivalent to about 5.4 billion euros. The cast was clear: 60% is contributed by the government, 20% KAI and local industrial partners, and the remaining 20% initially agreed with Indonesia. South Korea has opted for a gradual strategy, with blocking in blocks and a progressive nationalization of components. He does not seek to have everything from day one, but control each phase of the process. Indonesian participation has been one of the most unstable points of the program. Initially signed to finance 20% of development, But he stopped paying years later. After years of tension, In 2025 a new framework was agreed: Your contribution will be 600,000 million wones, about 415 million euros then. The agreement maintains some technological transfer and access to production for the Indonesian Air Force. South Korea will assume the rest. The project advances with or without them, but not without costs. The engine is today the main external dependence of the KF-21. Use General Electric F414, The same that propels F/A-18 Super HornetAssembled under license by Hanwha Aerospace in South Korea. Although that allows some logistics control, the supply is still tied to US authorizations. The South Korean industry already works in its own enginebut it is estimated that it will not be ready before the next decade. Meanwhile, any export plan of the KF-21 will continue to be subject to the ITAR regulations. It is the last piece that Korea still does not control. The KF-21 has been designed with export in mind. South Korea has already shown that you can sell light fighters such as FA-50. Now he wants to repeat the movement in a higher range. Philippines and Poland are among the possible KF-21 clients, And Egypt appears in the media radar, although without official confirmation. The only real limit is the American seal which still weighs on certain components, at least until there are motor and other components. Although the program advances according to the calendar, not everything is resolved. The first units that will be delivered from 2026 will only have Air-Aire capabilities. Air-Tierra weapons integration is scheduled for 2027, As confirmed by the Acquisition Programs Council. Nor are real operating costs, or their behavior in continued service. The South Korean Air Force will assume that risk in the first person. The KF-21 has demonstrated a lot in a short time, but the definitive test has not yet passed: that of daily use. It is not yet in service, but the KF-21 has already fulfilled part of its mission: to demonstrate that South Korea does not need to choose between being a client or staying out. It can be manufacturer. And it can be seriously. What comes later – exports, improvements, additional blocks – will depend on the operational result and the international context. But the key step has already occurred. Now it’s time to wait to know the results.

by

Let’s explain How to design your own business cards using artificial intelligenceand how to leave them all prepared to print. In this way, the AI is going to provide you with the maximum card design process, and you can concentrate on deciding what you want it to appear in them. Before starting, we will remind you of several things that should be taken into account before you put your visiting cards. Then we will tell you how to do conventional and capable of generating images from text, such as Chatgpt, COPILOT, Gemini or similar ones. And then, we will also propose other alternatives that you can also use. Before starting, some tips Before you start creating your visits card, you must first think what type of design you want use. You may want it to be casual, childish, you may want it more rocker for a festival, and so on. Think if you want to include an image, in the design composition, and even in colors. All this you can specify or use then to make your design. You should also think about The sector for which it is directed. If you write about technology, you may want to use some details or graphic elements related to it. It is also convenient Having your company or your personal brand on hand In the event that you want to put one on the card. In case of a generative AI, you can upload the image of the logo to tell you that the vintage, and in other tools you can put it by hand. You should also be clear and defined what elements you want them to appear on this visiting card. Obviously, you will have to put Your name and surname and a description of your position In the event that it is something professional, but you may also want to put your phone, email or even postal address. It is also convenient that you define Where do you want to place each element and the size of each of them. Even if you are going to do it with chatgpt, you will have greater control of the result if you define the position within the card that you want each of the elements to have. Finally, You should always check the result Before giving the design good. IA make mistakes, and you can meet poorly written words or letters, with drawings with defects or elements that make no sense. Do not be afraid of repeating the creation of design as many times as necessary until you give with the optimal result. Create your card with chatgpt and similar To create your visiting card using a generative AI with drawing functions such as chatgpt and similar, you can use a Prompt or simple request, carefully describing what you want That appears. We have left this one: “I want you to generate the image of a business card in which I put as a company name” (company name) “, with its logo located on the right. In the center to the left with large letters” (name) “, and underneath put with smaller print” (place in company). “You must include some information such as email (mail). With this, ChatGPT will generate the card design. Remember to put the data correctly and add elements you want. For example, you can attach to the prompt the company logo and tell you to include it on the visit card. In addition, you can write an answer to the result by instructions to improve specific elements. You can also Describe colors or typefacesas well as add any other element you want. Do not be afraid to correct the results and continue improving the elements until everything is as you want. Once you have created the card design, You have to turn it into something printable and cut -out. For that you can ask Chatgpt or the AI that you have used to generate a PDF, describing the folio A4 size or the one you are going to use, and that there are several cards on the page to be able to cut them. Use a prompt like this: I want to print this card. I want you to make an image in A4 size of a folio in which there are eight of these cards in two columns to be able to print and cut them. Do it in PDF. And with this, Chatgpt will make you a preview to print the way you have asked. Nor are you afraid to repeat the process if the result is not how you want.

China already has its “invisible hunt” ready for action, and twice

by

There is no official announcement. But China leaves clues again. This time they arrive from a Photography published in Weibo and replicated in x: two J-35 They fly in closed formation. What differentiates them from the prototypes seen so far are their construction numbers, “0011” and “0012”, clearly visible in the fuselage. It is a solid indication that the program has entered a limited series production phase, the typical LRIP prior to the operational deployment. LRIP registrations, emblems and a shark in the tail. The image seems to come from an official channel of the Chinese Navy. To the numbers are added other details that reinforce the hypothesis: national emblems in the vertical fins, a tactical gray free and a reason for a shark in drift. The specialist Andreas Ruprecht, Consulted by specialized means like War Zonehas repeatedly indicated these visual winks in Chinese naval aircraft. Click to see the publication in x The pilots also give clues: they carry bright blue helmets, exactly the type of helmet used by J-15 aviators in first-line units. All this suggests that these J-35 are already assigned to the Navy and in the validation phase prior to their entry into service. From FC-31 to J-35: the navalized variant that China needed. The J-35 derives from the FC-31, Shenyang’s furtive project for a more compact hunt than the J-20. The first navalized prototype flew in 2021; The second was seen in 2022 with a gray gray scheme of low visibility and, in 2023, blurred images of what could have been a third device emerged. Now, with the 0011 and 0012 specimens, we talk about units that already fit an initial serial configuration. The design is designed to operate from carckeners with catapults, such as Type 003 Fujianeven in tests. It is the logical step in an army that has been training in land facilities that simulates Catobar covers for years. Motors: WS-19 against WS-21, a puzzle still unsolved. The motor plant is still unknown. Some suggest that the land version, J-35a, already mounts the final WS-19, identifiable by darker nozzles. On the other hand, the naval specimens, with clear nozzles, could be driven by the WS-21, an evolution of the WS-13 used in the initial prototypes. There is no official confirmation and it is likely that Shenyang continues to adjust the engines in parallel to the progress of the program. Both airplanes carry a screwed Luneburg lens under their belly, a radar reflector that is installed when no total observability is required or when you want to mask the real firm of the device before third parties. Tests on aircraft carrier? For now there are no photos that demonstrate it. With airplanes apparently already in the hands of the Navy, the embarked essays are the next logical step if they have not already begun. There is also talk of a possible public presentation in September, during the acts by the 80th anniversary of the Japanese defeat in World War II. We will have to see if Beijing takes that occasion to exhibit it. One more piece in the puzzle of Chinese embarked air power. The J-35 adds to the KJ-600 early alert embarked the poaches that China has in development. Everything indicates that the country wants a more complex shipped air wing and comparable to that of the United States. It must know how long it will take to achieve real operational capabilities with this new generation of platforms.
