The chaos that AI has generated in personnel hiring has revealed a type of hidden talent: “invisible developers”

by

For years it has been repeated that to have a good work in technology It was necessary to cultivate a good public personal brand and maintain an updated and complete professional profile. However, more and more voices within the technology sector are dismantling that idea, ensuring that many of the most valued developers They don’t do any of that. They are not going to apply to dozens of job offers or optimize their visibility. “Invisible developers” are simply brilliant at their job. This invisibility is something that was put on the table Gergely Oroszengineer, analyst and author of ‘The Software Engineer’s Guidebook’ in a recent message in his X profile, in which he pointed out that this profile of “invisible developers” flies under the radar “the only way to find them is through references and specific searches”, assured the expert Candidates with AI have broken everything. The increase in responses generated by AI to job offers has completely broken the hiring system. They explained it perfectly from the Manfred technological employment platform, where a few years ago they received between 20 and 50 applications a day for each job offer, and now they receive more than 500. Various recruiters they explained on Reddit that this saturation of applications lowers the average quality of the applications and makes it difficult to detect real talent through this route. The situation is so extreme that, as Orosz indicated in an analysis from the tech job market posted on his blog, “many companies hire most engineers through contacts and referrals.” Internal recommendations matter more than ever. In this saturated scenario in which true talent goes unnoticed, word of mouth has become the most reliable hiring filter. It is estimated that around 80% of existing job offers are not made public and are filled internally or through references and recommendations from the employees themselves. In fact, many companies use referral incentives among their employees so that, when a vacancy opens, they recommend their former colleagues and acquaintances as candidates. As Orosz details in his analysis, recruiters increasingly look for candidates more among the pages of their agenda than among the applications that come to them. The myth of the hypervisible developer. Public attention usually focuses on profiles with a lot of activity on networks or with highly visible projects. However, different examples and testimonies reveal the rising trend of “invisible developers”: brilliant workers at their job with little or no activity on their public profiles. A clear example is found in the message published by Max Spero, co-founder of the AI ​​company Pangram, in which he compares the GitHub contribution profile of an unemployed 22-year-old developer, full of activity and contributions, and that of a prominent Google engineer, with a practically empty history. In response to that post, Konstantin K, a software developer from San Francisco, confirmed Spero’s message. “The top 1% of engineers I’ve worked with over the past 10 years didn’t have GitHub, LinkedIn or LeetCode, they don’t speak at conferences or publish podcasts. But they built systems that no one else can,” he wrote. Trust networks between colleagues. Other testimonialsamong which Orosz is also foundreinforce this idea of ​​”invisible developers” and agree that the most effective way to open job doors in the future is to be valuable to colleagues in the present. “From the outside you cannot know how good an engineer this person is until you ask former colleagues. There are many cases like this,” wrote Orosz in X. Even academic research suggest that internal networks—those formed by real collaborations, not superficial digital connections—have a direct impact on career opportunities. In other words, the professional prestige that these “invisible” employees generate within the teams in which they participate weighs more than any public presence and their colleagues become their guarantors to obtain a job in the future. Real contact in a digital setting. It is still paradoxical that, faced with the saturation of digital channels and the implementation of AI-based systems, the technology sector is returning to a classic model: relying on real recommendations to reduce uncertainty. Research reveals that recruiters prefer to spend time on references validated by employees or former colleagues, rather than analyzing hundreds of clone resumes generated with AI.

an AI that decides when to shoot has hidden where it is least expected

by

In recent months, Ukraine has seen technological leaps that until very recently were more typical of the realm of science fiction. Of the machines capturing and taking prisoners went to drones attacking on his own in a matter of weeks or even the arrival of a “general AI” capable of converting soldiers in “invisibles”. The latest: a kind of cross between Terminator and Predator. From improvised anti-aircraft weapon to autonomous system. Yes, Ukraine has turned urgency into advanced military engineering by developing what they have called like Predatoran automated machine gun turret initially created for the Magura naval drones could face Russian helicopters and fighters that They patrolled the Black Seaa space where air pressure on Ukrainian operations increased after the success of unmanned attacks against the Russian Fleet. The Predator debuted in combat end of 2024when its sensors and target acquisition capabilities allowed two helicopters to be shot down using missiles fired from other naval drones, and months later it helped shoot down a Russian Su-30, demonstrating that an unmanned explosive vehicle could also provide anti-aircraft cover. A twist. Once the success of the machine was seen, Ukraine decided to “hide it” where it would be a surprise to the enemy. It turns out that integrating this turret into a maritime platform was a complex challenge which made it necessary to guarantee stability in adverse conditions, precision in a moving hull and compatibility with guidance processes that combine optical sensors, artificial intelligence and gyroscopic systems. The Predator turret equipped on a small tracked vehicle Naval technology adapted for drone warfare. Thus, although it was born for the sea, recent tests of the Predator have confirmed its usefulness in the dominant theater of modern warfare: the FPV drone combat loaded with explosives, responsible for a growing share of Ukrainian losses on the ground. With 7.62mm ammunition, optical sensors, gyroscopic stabilization and automatic detection alerts, the system can be mounted on track vehicles or in the bed of a pick-up, shooting on the move and following minimum targets of just a few centimeters at 100 meters. And more. Artificial intelligence allows the turret identify threats and present options to the operator, who maintains the final decision to avoid fratricidal fires, while the new versions incorporate laser rangefinders and precision improvements adapted to drones controlled by radio frequency or fiber optics. From Ukraine to NATO. The rapid industrialization of the Predator (more than thirty units built and a plan to produce a hundred a month in less than half a year, with a unit cost of less than $100,000 for the Ukrainian forces) makes this system one of the most agile developments of the Ukrainian military complex. In fact, its success has awakened the NATO interestwhich invited the company to an Innovation Challenge and put the system to the test at an evaluation event in France, where the manufacturer presented it remotely as a modular and immediately deployable solution to threats that evolve with weeks, not years, of margin. Additionally, UGV Robotics plans a larger caliber model, the Apex Predatorwith .50 ammunition and the ability to intervene against heavier aerial threats, aiming to turn these turrets into an exportable standard for Western allies. The new paradigm of Ukrainian defense. The story of this turret illustrates how Ukraine is integrating naval and land capabilities into the same combat ecosystem automation basedmodular sensors and systems capable of operating on unmanned platforms, a strategy driven by constant pressure from Russian drones and the need to protect both infantry and exposed vehicles. In this context, a design conceived so that an explosive drone would not be shot down from the air is now transformed into a ground defense against cheap and lethal swarms, making the Predator a symbol of Ukraine’s shift towards a distributed, adaptive defense focused on neutralizing asymmetric threats before they reach their objective.

Stephen Hawking left a hidden treasure that has just been discovered. The problem is that it is in the form of floppy disks

by

The Cambridge University Library houses several historical treasures including letters from Isaac Newton and notebooks from Charles Darwin. Now they will take care also of manage 113 boxes with documents and memories of the physical Stephen Hawkingbut in those boxes they also found a surprise turned into a challenge: floppy disks. Lots of them. Computer pioneer. The famous physicist was an early user of those first computers in which data was stored on floppy disks. When he suffered from ALS this was a very important resource to be able to communicate and work, and now those disks that have just been discovered could contain all kinds of revealing data about Hawking’s life and work. Future Nostalgia. That’s what it’s called the project of the University of Cambridge and its library that precisely tries to safeguard all that information that in the past ended up being stored on floppy disks. Recovering such data is not easy when so much time has passed, and this project tries to educate about the best ways to preserve said information and transfer or recover it from those floppy disks. A format with an expiration date. Although one would think that floppy disks are a more secure way to store data than paper and ink, this physical medium also has clear disadvantages. The iron oxide covering the thin layer of plastic can degrade and lose its magnetic capabilities, meaning data could be lost forever. Each floppy disk is a world. With old books there are not too many problems when it comes to retrieving the information: you open them and read them (if you understand the language, of course). With floppy disks you need the hardware to be able to read them—a compatible disk drive—and also figure out how they are formatted. Leontien Talboom, responsible for this project, explained How to also clean those floppy disks was complex and there were various methods that they were exploring. These included the use of hand soap or isopropyl alcohol. Hawking used both a PC and a Mac. The disks arrived at the project in two batches. The first, with five and a quarter (5.25 inch) disks formatted on an MS-DOS based PC. The second, with three and a half disks, somewhat more recent and that were still used on an old Mac. According to Talboom, they are mainly talks that Hawking gave: “from a technical point of view they are really interesting because his talks were so big that he had to divide them into several floppy disks.” I wrote to speak. Hawking’s illness left him unable to speak for himself, so for years he used various voice synthesizers to express his ideas. Precisely for this reason he wrote so much on the computer and saved those documents on disk: this allowed him to use them later so that his synthesized voice could read said documents. Different discs, different readers. Although 5.25″ and especially 3.5″ discs were the most widespread, other formats were also seen such as eight inch discs which for example were used in the Churchill Archives Centre. Chris Knowles, one of the Future Nostalgia participants, explained how he bought a player for these discs on eBay. “It was a miracle that it worked,” but that allowed him to recover the information from those disks. Forgotten formats. They have also received some three-inch floppy disks, a much less widespread and peculiar format that had some success in the United Kingdom before the 3.5″ format was clearly imposed. To recover them, they ended up using an old reader manufactured by Amstrad that they had to modify to bring it back to life. And then there’s the software problem.. The information recovered from these disks can also pose another challenge: that it was created with software that was abandoned and even ended up disappearing. Some disks, for example, had documents written with a missing word processor called Diamond Word. That’s where a kind of “translation” comes into play to convert those files into something readable in the current era. Safeguarding our past. This work demonstrates how critical it is to try to protect and recover information from these old formats. Many of those floppy disks are 40 or 50 years old, and as Knowles says, “old emails and work calendars may not look like historical documents. They might seem banal. But they’re what Newton’s or Darwin’s letters would have looked like 200 years ago. Now they are fascinating documents that open a window to the past.” In Xataka | The 20 most important personal computers in the history of technology

Hidden for 43 years, this Mercedes-Benz 500 SL is the closest thing to a toy preserved in its packaging: it still smells new

by

Who They collect toys and dolls They know that preserving a piece in its original case for decades is a precious achievement, a symbol of care and respect for the history of the object that also increases substantially its value. Now, imagine that same experience, but with a car. It is something much more difficult to achieve because, if only to give yourself the pleasure of drive it from time to timeand compensate the money that has been paid for it, it is easy and understandable for the vehicle owner to fall into temptation. However, that is precisely what SL Shop, a workshop specialized in repair and restoration of Mercedes-Benz and They tell it on their blog. The most surprising thing – and what makes this find so unusual – is that the owner’s intention was never to drive it, but rather to preserve it intact as it left the factory and without the slightest wear. If cars were sold in a blister pack like toys, this would be the equivalent. The dream piece for any collector It is common for a legendary car stored in a barn to appear from time to time. under decades of dust and rust. However, this Mercedes-Benz 500 SL R107 from 1982 has been discovered after 43 years carefully stored in a private garage in the United Kingdom, with just 68 kilometers on the odometer and in an absolutely pristine state of conservation. It has only traveled the 42 miles that were done on it at the factory and at the dealership before delivery. It is a true time capsule on wheels, which seems to have just rolled off the assembly line a few days ago. Sam Bailey, founder of The SL Shop, a classic Mercedes specialist who took delivery of the vehicle, said: “This 500 SL is the truest reflection of the original R107 plans.” In fact, as he himself acknowledges in a video they have uploaded to his YouTube channel, the car It even keeps the smell of new. “You could almost bottle it. It’s just heaven,” Bailey said. This example was purchased with all the original extras available on November 30, 1982 by a local watchmaker, who decided never to register this Mercedes-Benz 500 SL. In fact, even the delivery of the vehicle it was done in a truckso it didn’t even travel the distance between the dealership and the owner’s home. Since then, the 500 SL has been in storage under controlled temperature and humidity conditionsavoiding any deterioration. The Blue Green Metallic paint remains intact and rust-free, and the original dealer stickers are still attached, something very rare to find on collector cars. The car shows amazing conservation details: Waxoyl protective wax still covers the engine and exhaust, while the Michelin XWX tires remain. without having traveled even a kilometer. The interior preserves the leather, the original woods and even the authentic smell of the 80s. Among the factory options it has air conditioning, heated seats, ABS and metallic paint, valued in 1982 at more than 2,746 euros. The car has all its original elements and is in an impeccable state of conservation except for one detail. The Mercedes-Benz badge on the hood is not the original: it is a faithful reproduction that was made by the owner in solid silver. It was put up for sale: it will never be sold As Bailey tells it, he learned of the existence of this gem more than fifteen years ago, when during an exhibition, its owner approached them to tell them the story of his little automobile treasure. When Bailey asked if he would be willing to sell it, the owner responded with a firm no. But life takes many turns. In August 2025, Bailey received a call from the owner of the 500 SL offering it for sale. Knowing its history, the businessman has decided to buy it and He has promised to never sell it. To maintain the legacy of its first owner, the 500 SL will remain in an exhibition space open to the public and air-conditioned for conservation, where it will serve as a reference for future restorations. After all, there is no other car like this outside the Mercedes-Benz Museum in Stuttgart. That makes it a collector’s piece with incalculable value. The Mercedes-Benz 500 SL R107 was at the time the pinnacle of luxury and power German, with a 5.0-liter V8 engine that delivered 240 horsepower and a four-speed automatic transmission. Its design, technology and comfort rivaled sports cars from brands such as Ferrari and Maserati, but with an outstanding reputation. for its reliability. This model is recognized as a symbol of German engineering from the early 80s, capable of combining performance, elegance and durability, values ​​that are evident in this unique example, practically new after more than four decades hidden so that four decades later, whoever has the privilege of being able to sit inside, can smell the new smell of the first day.

If you have installed iOS 26 and you do not like the new transparent design, you just have to press this hidden button on the settings

by

iOS 26 has not only brought an important change in the name, It also comes with the largest redesign of the iPhone for years. The interface Liquid Glass is characterized by being full of transparencies, Something that not to everyone will convince him. Liquid Glass cannot be deactivated, but there are ways for your iPhone to have a design almost like before. Goodbye to transparencies in iOS 26 As the saying says, for tastes: colors. There will be those who are delighted with Liquid Glass, but one thing is true: The readability of some elements is harmed With so much transparency. I no longer talk about Transparent icons do not find appsbut of menus and controls that overlap and do not finish seeing well. If you are in my team, this option is for you. The magic button to get rid of transparencies. The button we are talking about is’Reduce Transparency ‘ And it does just what his name says. To activate it you simply have to go into adjustments – Accessibility – screen and text size and disable it. The result will be that the translucent effect will be reduced, causing the elements to distinguish much better. Let’s look at a couple of examples: The APP photos controls look fatal when we see an image or full screen. The APP photos is a good example that transparency is not always better. Looking at this full -screen image, the buttons look much less clear with activated transparency. In addition, the effect is changing as we move the photo, causing the background to move and dizzy even more. The control center is much more readable. The control center also benefits from this option, but above all Where I have noticed is in the notification panel (in the cover photo). Here we have many small texts and we usually slide to see all notifications, making everything move and cost us more to read. If you want to improve the readability a little more about the option ‘Increase contrast’ It is just below. If you active, the effect is minimized Glow And everything looks flatter. And finally, if you don’t like Liquid Glass, there is plenty of saying that Do not activate transparent icons, Better to leave it in the ‘by omission’ mode. Two extras: Telephone and Safari The redesign also reaches system applications and, again, It is not for everyone. The good news is that they allow us Go back and have the design before. One of them is the safari browser. Safari has a new design, but we can return to the old if we want. By default, when IOS IOS 26 will activate the new compact design that the search bar and two buttons have on the sides. If you go to settings – Safari you can choose whether to keep the re -but without the compact design or on the contrary Return to classic design with the top bar and the buttons below. The telephone app also has a new design. In the case of the telephone app, when opening it asks if we want to try the new design. As in Safari, The interface is more compact And it offers us less tabs at the bottom, in addition to eliminating the “calls/losses” coach from the top. If you do not convince you, you can click on the top button to the right and return to the classic design.

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.

The hidden reason why Elon Musk Lanza Satellites of Archienemigos like Jeff Bezos: The radio spectrum

by

On Monday morning, Spacex completed its 100th launch so far this year. But aboard the Falcon 9 rocket there were no new Starlink satellites, but a lot of 24 competition satellites. How have we reached a point where Elon Musk and Jeff Bezos, rivals on so many fronts, collaborate in space? A little context. Starlink has been growing without opposition for six years. At this time, Spacex has deployed More than 8,000 satellitesconsolidating an almost absolute domain of the satellite broadband Internet market. Now, a competitor with a comparable financial muscle has entered the scene: the Amazon Kuiper Project. The company founded by Jeff Bezos has begun to display its own megaconstellation to offer high -speed connections worldwide and compete directly with the Elon Musk service. Time against. The main challenge for Kuiper is time. The license granted by the Federal Communications Commission (FCC) of the United States requires him to have half of his constellation in orbit (that is, 1,618 satellites of a total of 3,232) before July 2026. Unlike Spacex, which has a complete vertical integration, Amazon does not manufacture its own rockets. To fulfill the deadline, the technological giant made in 2022 the “greater commercial acquisition of history of history”, signing contracts with ULA to use its atlas V and Vulcan rockets, with Arianespace to use the European rocket Ariane 6, and with Blue Origin, the aerospace company of Jeff Bezos himself, to use the gigantic new Glenn rocket. The problem is that most of these pitchers are new and have suffered important delays. They are just business. Although Bezos tried to prevent Amazon from using Spacex services, the most honest option with shareholders was to hire several Falcon 9 rockets, which thanks to their unique reuse capacity usually offer the lower price per kilogram Put in orbit. Spacex has already shown that he is willing to launch satellites of his competitors. Between 2022 and 2024 he launched four lots of satellites for Eutelsat Oneweb, his European rival, after the Russian invasion of Ukraine took the Soyuz and proton rolling from the market. For Spacex, this is a round business because the money of its competitors is pocketed, which can reinvest in its own satellite constellation. But there is another reason. A strategic issue that goes beyond the launch business. The coin of covert change is the increasingly saturated radio spectrum. According to one Wall Street Journal ResearchSpacex has used its dominant position in the release market to press its rivals and obtain a crucial advantage for Starlink: spectrum rights. The radio spectrum is the electromagnetic wave set that are used for wireless communications. It is a resource finite, invisible and absolutely essential so that satellite constellations can send and receive data without interference. Governments around the world, through organizations such as FCC in the United States, are responsible for assigning rights to use it. Spacex needs more spectrum. And he needs it desperately to be able to serve the More than four million Starlink users As it continues to expand. According to the Journal, Musk’s company would have asked companies such as Oneweb and Kepler Communications to give him part of his spectrum rights as a condition for launching his satellites. Although Spacex denies it, the report details how Oneweb, after running out of the Russian rockets, reached an agreement with Spacex that included “spectrum concessions” to ensure the releases it needed. Elon Musk’s web. This strategy places Spacex competitors in an incredibly difficult situation. It is a dilemma that the analyst Tim Farrar Describe as “Carefully choose”. Companies such as Echostar or GlobalStar have had to decide between going through the Spacex ring, giving competitive advantages, or paying more for slower access to space with other rocket companies. If there are. Ast Spacemobile, who had opted for the New Glenn rocket of Blue Origin, found that Bezos’s rocket would not be ready on time And their satellites, much heavier than expected, will have to wait. Apple’s case. In 2022, Musk I had offered Apple exclusive access to Spacex For 5,000 million dollars, an offer that Apple rejected. Apple ended up closing an agreement with GlobalStar for its satellite emergency service, but later, the delay in the launch of GlobalStar’s satellites by Spacex seems to have benefited Starlink. The explanation of the delay and renegotiation of the launch contract seem to have to do with that Apple will end up reaching an agreement To offer Starlink Direct-to-Cell on the iPhone 13, a model that is not compatible with the GlobalStar service. This gave Starlink an advantage in the race for the cell connection at a time when Apple already debated internally if he could compete with the rhythm of Spacex. The giant Starlink. In the end, each launch of a competition or agreement satellite by the spectrum becomes a tactical victory for Elon Musk. Not only does it charge for the service, reinforcing the finances of a company whose income They are about to overcome NASA’s budgetbut it uses its domain to ensure the most vital resource for the future of global communications.

Japan believes to have the largest deposit of rare earths hidden on a tiny island. And it is already date to extract them

by

The Rare earth They are an element of great economic and geopolitical value and China stands as the greatest power. To its Japanese neighbors He didn’t make any grace have to depend on them and, after an exhaustive search, a year ago they found the treasure: A huge site of rare earths at the bottom of the ocean. Japan has already set date to start extracting them. January 2026. It is the date on which Japan will begin with the first test extraction, according to Nikkei Asia. They expected to start this year, but the delivery of the necessary duct to reach the deposit did not reach last May and delayed the project for a year. The duct, manufactured in the United Kingdom, has cost 12,000 million yen (about 71 million euros) and will allow them to reach a depth of 5,500 meters. The Chikyu. The Japanese Marine-Terrestrial Science and Technology Agency or JAMSTECfor its acronym in English, will use the chiichyu, the name received by the Japanese drilling boat with which these valuable minerals will extract. In 2022 they already did a test at 2,500 meters deep In front of the coast of the Ibaraki Prefecture, but the challenge they face now is to drill more than double deep: 5,500 meters. If they get it, it would be the first time that rare earths are extracted to so much depth. In the first phase, Chikyu will extract 35 tons of mud. It is estimated that a ton of mud contains about 2 kilos of rare earths, so, in the best case, we could be talking about 70 kilos of rare earths. A key discovery. As we said, Japan found the site almost a year ago in front of the island of Minami-Torishima, located about 1,900 kilometers southeast of Tokyo. The site is located in the exclusive economic zone of Japan, so their extraction corresponds to them. Among the minerals it contains, one of the most abundant would be gadolinio, used in the nuclear industry, and the disposium, used mainly in magnets for electric vehicles. It would also be rich in manganese, cobalt and nickel nodules, key components in the creation of batteries. The amount is not clear and is decisive. At first there was talk of a site of 16 million tons, which would place Japan in third place behind China (44 million) and Brazil (21 million). However, a Analysis of the University of Tokyo He pointed to the loot would be much more juicy: 230 million tons. If confirmed, Japan would overcome China and be placed as the largest reserve of rare earths in the world. Independence. Japan’s efforts to find rare earth date back to 2022 and had a clear goal: to be independent. Currently, Japan depends on imports to meet their needs of rare metals, with 60% of them from China. The Japanese government invested 6,000 million yen (about 42 million euros) in the first extractions and have made it a priority since then. Friction. As we said, China currently has the largest reserve of rare earth and that gives it A huge power. Just a few weeks ago something unusual happened: A combat fleet, headed by two Chinese aircraft carriershe entered the Japanese ZEE near the island of Minamitori. Japan He did not confirm If he presented a formal protest and just declared that he had sent “the appropriate message.” It is not the first time that China enters the Japanese area, nor are the friction between the two countries, But it is certainly a somewhat controversial maneuver given the economic importance of the area.

In 1950 two scientists wondered if possible a nuclear bomb of 10 gigatons. Its results are hidden locked up

by

On October 30, 1961, a Soviet bomber furrowed the skies of the Arctic towards Novaya Zemlya. Under his fuselage he hung an artifact the size of a bus: an unprecedented nuclear pump. At 11:32, the called TSAR pump He released. A parachute slowed its fall, allowing the plane to move away. Then, a detonation illuminated the sky with a fireball of almost 10 kilometers in diameter and a fungus -shaped cloud that amounted to more than 65 kilometers. The show was surreal: the pump, With 50 megatones explosive (more than 3,300 times that of Hiroshima), became a symbol of the Nuclear madness. But it could be much worse. The awakening of a new era. With the atomic bombardment of Hiroshima and Nagasaki In August 1945, the world changed irreversibly. Those bombs, 16 and 21 kilotons respectively, they marked the beginning of the destructive power without a paragon of Nuclear weapons. However, despite their fearsome capacity, these weapons were only the first step towards a much more sinister technological escalation. What would later transcend the most reckless imagination. The most powerful pump ever detonated would be That Soviet tsar of 50 megatones, although designed to reach 100. However, the most disturbing thing is that this was not the summit. In hidden, the United States had still planned More huge. The “Super” concept. Hiroshima and Nagasaki bombs were based In fission: A chain reaction in which heavy nuclei are divided releasing energy. But as we said, in parallel to their development, some scientists imagined a second stage: The fusion. This implied union of light nuclei (as deuterium and tritium) to form a heavier one, releasing even more energy. It happens that this reaction required an initial fission explosion to activate, which would give rise to the concept of the Hydrogen pumps. In the 1940s they were just a theoretical speculation … but everything changed very soon. Photograph of a replica of the tarum pump housing Communism comes. After the detonation of the First atomic bomb Soviet in 1949, the United States accelerated its thermonuclear programs. The fear of communism, enhanced by the revolution in China that same year, made the National Security Council recommend quadruply military spending. In that context, the figures of Edward Teller and Stanislaw Ulam appear, who devised The design that even today supports the H bombs. In 1952, the “Mike” test of Operation IVY demonstrated for the first time the Thermonuclear principle: an explosion of 10.4 megatones (500 times Nagasaki) that left a crater of 1,900 meters wide. Despite such force, that was not enough for Teller. The Soundy germ. Two years later, in 1954, the so -called “Shrimp” bomb during the Castle Bravo test. A powerful explosion was expected, but the result of 15 megatons (1,000 times Hiroshima) even surprised its designers, both by strength and by the devastating level of radiation released. However, Teller’s impetus did not stop there either. I wanted more, Much more. It was then that one of the most delusional and terrifying projects of nuclear history emerged: the Sundial Project. Designed by Teller and his colleagues from the Livermore Radiation Laboratory, the plan proposed a new destruction scale: no already kilotons or megatones, we entered In the gigatons. A couple of brothers. They were designed Two weapons: Gnomon and Sindial. Gnomon would act as “primary”, with a detonation of 1,000 megatons aimed at detonating Soundy, which would reach a power of 10,000 megatons, that is, 10 gigatons. For placing it in perspective, he thinks again The image of the beginning. Well, the figure exceeds 200 times the tsar bomb, and almost does not fit in the conceptual framework of the physics of conventional explosions. The potential apocalypse. The logic behind Sindial overflows any traditional calculation. To such powers, the laws of escalation of destruction They lose any validity: The heat, pressure and energy released would be so monstrous that, a priori, they would open a hole in the atmosphere. In fact, A report Del Bulletin of the Atomic Scientists pointed out that a pump like a sundial, detonated about 45 kilometers of altitude, could cause fires in an area of the size of France. The death toll would be unthinkable, not only because of the immediate explosion but by global radioactive sequels. Hiroshima, with 140,000 victims, would be a sigh against cataclysm that would represent Sindial. It was not science fiction. Although it might seem like a laboratory fantasy, the Sundial Project It was not a joke or an eccentric occurrence. Declassified documents and historical analysis indicate that Livermore’s team worked seriously For years in the development of Gnomon, with concrete plans to test it in the Redwing operation of 1956. That test was canceled, but the mere existence of the plan shows to what extent the fear, scientific ambition and deterrence had pushed the superpowers to border the abyss of the unacceptable. Echoes of Sindial. Suindial never materialized, but his mere conception forced A critical reflection In American politics. The growing destructive power of these weapons overflowed not only military strategy, but also ethics, logistics and land physics itself. While many ruled out their tactical utility for being impracticable (a pump of such dimensions was impossible to launch), its potential as an instrument of symbolic terror was enormous. As with The TSAR pumpits value was more political than operational: a floating threat that showed how far a nation could go if I wanted. Monster in the shadows. Finally, the Soundal project is It was diluting between political restrictions, international treaties and practical sense (without serving as precedent). The Ratification of the treaty Partial prohibition of nuclear trials in 1963 was a brake on atmospheric tests, which in practice made it impossible to continue advancing in the development of extreme performance weapons. The strategy then went on to favor smaller, portable and operational multiple eyelets, leaving behind the vision of total apocalypse that represented Sindial and its cousin Soviet sister. Imagine the unimaginable. What’s doubt, today sundial is just a footer … Read more
