invisible

The most famous bridge in the US recorded more than 2,000 suicides. Until in 2024 they found an “invisible” solution

by

When the golden gate Opened almost a century ago, it was celebrated as an architectural triumph of engineering and modernity. It happens that the history of many of the great works has had a second reading. Sometimes they have failed due to technical problemsand others have ended up marked by uses that no one foresaw. Over time, a bridge can become something very different from what its plans imagined. The bridge and its dark history. The Golden Gate Bridge, inaugurated in 1937 between San Francisco Bay and the Pacific, has been for decades one of the places most associated to suicide in the United Stateswith a rate of more than 2,000 jumps confirmed and a real figure surely higher because not all cases are seen nor all bodies are recovered. In 2006 there was one of the worst years, with at least 34 deathsand that was also the turning point in which relatives of victims, as Paul Mullerdecided that it was unacceptable to continue living with that routine of tragedies without a physical and effective response on the bridge itself. The barrier that changed destiny. The solution ended up being a deterrent system “invisible” installed along both sides of the bridge, one based on stainless steel cables of marine grade placed about six meters below the pedestrian walkways. It is not something that can be seen from afar or from normal traffic, but it is evident to those who look over the edge. The idea is simple and tremendous at the same time: if someone tries to jump, they fall on that structure, are injured or shocked, and the possibility of completing the fatal fall into the water is cut off. The barrier created to prevent suicides The effectiveness of the new impact. For many years the Golden Gate recorded an average of about 30 deaths annuallya figure that seemed entrenched and almost impossible to break. However, in 2024, with the facility entering its final phase and with adjustments still underway, the deaths they went down to eight. Last year, in 2025 and with the system already operating for twelve months, there were only four and there were no falls between June and December, a stretch that could be one of the longest without suicides on the bridge, although old records are not always complete. By the way, from the beginning of 2026 there is already a casewhich reminds us that there is no such thing as zero risk. That said, the general decline is so evident that even its promoters see it as clear proof of effectiveness and a mirror for the rest of the hanging architectures. Surveillance and intervention. The barrier does not act alone, because the bridge maintains an electronic surveillance system and a team of agents whose task is to detect and stop attempts before they occur. In the last year, 94 successful interventions were achieved, about half of what was normal before full installation, suggesting that the problem does not disappear suddenly. In fact, there are still people who come with the idea of ​​jumping, but now the margin of action is greater and death is no longer as immediate or as certain as it was for decades. Installation of anti-suicide barriers, February 2020 Against inertia and cost. The truth is that the installation of the barrier came after a very long road full of political blocks, doubts about aesthetics, discussions about price and debates about if it would really work. Already in 1939 it was recommended to raise the railings, but for decades measures were avoided while the death count rose from 500 to 1,000 and it continued to grow with chilling regularity. The organized pressure from family and professionals ended up crystallizing at the Bridge Rail Foundationand after years of paperwork the work started in 2018. The project also became very expensive, going from an estimate of 76 million dollars to a final cost of 224 million dollarsand even took longer to install than the bridge itself to build. The “invisible” barrier Why it saves lives. One of the central ideas is that reducing easy access to a lethal method works, even if it sounds too simple. A 1978 study by Richard Seiden, at the University of California at Berkeley, followed 515 people who had gone to the Golden Gate with the intention of jumping and were deterred, and concluded that 94% were still alive or had died of natural causes. This reinforces the idea that many suicidal crises are acute and not permanent, and that placing a specific obstacle at the exact moment can make the difference between dying and surviving. Bridges and the same problem. There is no doubt, the Golden Gate incident was not an isolated case, and there are other iconic bridges that have ended up with a similar reputation by becoming recurring scenes of suicides. In the United States, the royal gorge bridge next to Hoover Dam, or the Chesapeake Bay Bridgethey have had known histories and episodes that have fueled debates about surveillance and barriers. In Canada, the Bloor Viaduct in Toronto was for years one of the most problematic points until it was installed a great prevention structureand something similar happened in the United Kingdom with the Clifton Suspension Bridge in Bristol, where the combination of height, accessibility and symbolism forced action and reinforce early intervention. Also in Australia, the Sydney Harbor Bridge has been targeted of concern and initiatives preventive, and in Europe there are numerous cases on urban bridges and high-rise viaducts that share the same pattern: very busy and at the same time very exposed. The same idea is repeated in all of them, when a bridge becomes a known point, it is not just a problem of physical security, it is a social phenomenon that feeds on itself, and the more famous it is, the more important it becomes to cut that inertia before it becomes part of your identity. The legacy. The Golden Gate had been in operation for decades … Read more

the secret was an invisible ice “blanket”

by

For decades, planetary geologists have faced a paradox that didn’t quite add up. On the one hand, the missions like Curiosity in Gale Crater show irrefutable evidence that there were lakes of liquid water for thousands or millions of years. On the other hand, climate models insist that ancient Mars It was a cold place.with temperatures well below freezing point. A new paradigm. The question in this case is quite clear: how can there be stable liquid water on a planet where the thermometer barely rises above zero degrees? A new study led by Rice University and published in AGU Advances seems to have found the missing piece in the puzzle: seasonal ice shields. The LakeM2ARS model. To solve the mystery, the team of researchers developed a specific model called LakeM2ARS. This model included everything we know about terrestrials, but adapted to the extreme conditions that existed on Mars 3.6 billion years ago. That is, a climate with less sunlight due to a younger Sun, an atmosphere with much more carbon dioxide and much more aggressive freezing and thawing cycles than those on Earth. Using these models, the researchers began to apply different climatic situations, covering a period of 30 Martian years, which is equivalent to 56 Earth years. The results in this case pointed to something quite fascinating: the water in the lakes only froze on their surface, creating a shield of ice. A natural “blanket”. The research introduces the concept of “ice shield” or “natural blanket.” Instead of being a solid block of ice, the Gale Crater lakes they would have been protected by a seasonal ice sheet thin enough to allow dynamic processes beneath it. In this way, this “blanket” acted as a thermal insulator, since ice has a low thermal conductivity. The good thing about this is that once a layer forms on the surface, the liquid water underneath is “trapped” and protected from the frigid air, maintaining a stable temperature even if the thermometer plummets outside. Another advantage. Beyond this we can see that the low Martian pressure causes liquid water to tend to sublimate quickly. The ice thus acted as a physical plug, conserving the water inventory for decades or even centuries. But it is not that the water underneath was completely cold, but rather that since it was a thin layer, sunlight could pass through it (similar to what happens in the lakes of the Dry Valleys of Antarctica), generating a slight internal heating. The missing piece. One of the biggest criticisms of the cold Mars hypothesis was the absence of geomorphological traces. The big question we can undoubtedly ask ourselves is that if Mars was a freezer, where are the large moraine deposits and the scars left by the glaciers as they advance? The Rice University study gives an elegant answer: the ice was too thin. Since they were not massive glaciers, but rather thin and seasonal layers, they did not have the weight or dynamics necessary to erode the terrain drastically. This fits perfectly with Curiosity’s observations, which show fine-grained lake sediments, typical of calm waters, and not the chaos of rocks that a glacier would leave behind. Microscopic life. This discovery changes the rules of the game for astrobiology, which wants above all to search for evidence of life on the red planet. In this case, the theory is put forward that if Martian lakes were sealed by ice, they became extremely stable environments. Under the ice, life would have been protected from harmful UV radiation and extreme temperature fluctuations. This is why Mars did not need to be a tropical paradise to be habitable; It was enough for him to have a good “armor” of ice that would keep his liquid oases safe from the icy vacuum of space.

There is an invisible chip in every USB-C cable that decides whether your phone charges fast or slow: almost no one knows it exists

by

There is a small and notable chip in our USB-C cables. This is the so-called “e-Marker”, which is especially important. The reason is simple: when we connect a cable to a device, it is responsible for indicating to those devices whether the cable supports more or less transmission or charging speed, for example. USB-C chaos is a little less chaos. USB-C connectors completely dominate the market, especially after European regulations that require them to be used to charge mobile phones and other devices. Although they have become the Swiss army knife for connecting all types of devices and peripherals, it is not easy to know what we can do with a cable when we connect it to our mobile phone or laptop, for example. And that’s where the e-Marker chip (Electronically Marked ID chip) comes in, a fundamental yet invisible component of the connectivity of our devices. In Xataka We criticize the EU a lot with its obsession with regulating Big Tech. There are at least two examples that justify this obsession A chip to identify everything. The official specification of the USB-C standard clearly indicates the mission of this chip, which is responsible for showing what capabilities the cable in question has. The document that talks about this chip is the one dedicated to USB Power Delivery, the power delivery function through these cables. Specifically, the identification data includes: Manufacturer and model of the cable. Signaling protocol: that indicates the maximum transmission speedthat is, if it is a cable with USB 2.0 support, or USB 3.2 of one generation or another (Gen 1, Gen 2, etc.). Active construction (in long cables there may be chips that regenerate data signal to act as a kind of repeater) or passive construction (they do not alter the data signal). How much power does the VCONN pin (intended to power accessories) consume? Whether the cable can support 3A (standard) or 5A (required for powers from 100 W to 240 W). Latency (signal delay over the cable). RX/TX directionality (how the high-speed cable pairs are configured). SOP Controller Mode: Whether the cable controller can communicate independently with the charger or device Hardware/firmware version. One of the sections of the USB Power Delivery specification that talks about this chip. Source: USB.org An active safety mechanism. The e-Marker is not only official, but is a mandatory part of the USB Power Delivery (USB-PD) specification dictated by the USB Implementers Forum (USB-IF). This chip acts as an active safety mechanism, and during the power negotiation phase, the chip tells the charger “I am a cable certified to support up to 100W” (for example). If the charger does not receive that digital confirmation, it will assume that the cable is basic and cheap, restricting the flow of power or data transmission. Does your phone charge slowly or is the transfer using pedals? In fact, if a USB-C cable does not have an e-Marker chip, most device drivers will automatically treat it as a USB 2.0 cable. That means that even if the cable is physically capable of more, the speed will be limited to 480 Mbps maximum, and charging will also be slower. With 3A you can reach 60 W at 20 V, so even so this section is not so affected and it also depends on the charging capacity of the charger. {“videoId”:”x8dmqaj”,”autoplay”:false,”title”:”One USB-C TO RULE THEM ALL- the European Union approves a single charger for mobile phones”, “tag”:”webedia-prod”, “duration”:”54″} The rails. High-speed cables (USB 3.2, USB4, Thunderbolt) have multiple pairs of copper wires designed to transmit data in parallel. The e-Marker tells the device “I have all the threads necessary to activate dual lane mode.” If this confirmation does not arrive, the transfer speed is again limited. The e-Marker on long cables. Another function of the e-Marker, as we said, is to identify the length of the cable. At high transmission speeds the signal degrades very quickly, and the e-Marker is responsible for notifying you, allowing the device (mobile phone, computer) to adjust the signal strength to compensate for potential data loss. Support for alternative video modes. Another option that this chip enables is to indicate what video connection standards the USB-C cable in question supports, and if, for example, it has the necessary bandwidth for 4K or 8K resolutions. There are “readers” of the information provided by the e-Marker chip, although they are not cheap: this one from ChargerLAB costs about 140 euros. Two key pins. The “brains” of a USB-C connector are located on two specific pins known as the configuration channel (CC). These pins (CC1 and CC2) allow, for example, the orientation or reversibility to be detected. Since the connector is reversible, the device needs to know which side you inserted the cable to activate the appropriate data pins (TX/RX). When connecting it, the side will be identified, and based on that the rest of the pins are switched for transmission. The other pin of the configuration channel becomes Vconn to power the e-Marker chip. In Xataka | Mobile phone manufacturers first stopped including the charger with every purchase. Your next threat is clear: the USB cable (function() { window._JS_MODULES = window._JS_MODULES || {}; var headElement = document.getElementsByTagName(‘head’)(0); if (_JS_MODULES.instagram) { var instagramScript = document.createElement(‘script’); instagramScript.src=”https://platform.instagram.com/en_US/embeds.js”; instagramScript.async = true; instagramScript.defer = true; headElement.appendChild(instagramScript); – The news There is an invisible chip in every USB-C cable that decides whether your phone charges fast or slow: almost no one knows it exists was originally published in Xataka by Javier Pastor .

an invisible weapon that blinded his soldiers without firing a single bullet

by

The number of Venezuelan casualties after the United States incursion in Caracas and the subsequent capture of Nicolás Maduro varies with the passing of the days and the sources, but it seems clear that it amounts to at least double digits (we speak of up to 100). In any case, another piece of information has now been revealed that amplifies the mission. In reality, Washington’s key weapon did not fire a single bullet. The attack that was not heard. Yes, the American operation in Caracas was not defined by explosions or columns of smoke, but by the sudden silence of radars, radios and command centers, a demonstration of force in which more than 150 aircraft acted in a coordinated manner to enter, hit and leave with hardly any visible resistance. In fact and how explains the Wall Street Journalthe key was not to destroy the enemy, but to leave him blind and disoriented from the first minute, unable to understand what was happening or to react coherently while special forces captured Maduro in the heart of Venezuelan power. The invisible weapon. At the center of that blackout was the EA-18G Growler, an aircraft that does not attack people or physical positions, but rather the opponent’s nervous systemspecialized in locating, jamming and neutralizing radars and communications until turning an apparently solid defensive framework into a collection of mute sensors and useless screens. While stealth fighters and bombers performed deterrence and targeted attack functions, the Growler ensured that the Venezuelan defenses they will never get to see them clearly, demonstrating to what extent electronic warfare has ceased to be a complement and has become the precondition of any modern high-intensity operation. Blind before hitting. The logic applied in Caracas reflects a lesson learned and refined in Ukraine– It is not necessary to physically destroy all enemy systems if you can overwhelm, confuse or fool them until void your operating profit. The Growler can simulate multiple targets on the radar, flood the electromagnetic spectrum with noise, interfere with command links and, if necessary, guide anti-radiation missiles against active emitters, creating temporary windows of absolute superiority that allow helicopters and ground forces to operate with minimal risk even in theoretically defended environments. The Russian defenses that did not fire. They recalled in Insider that the most striking result was that none of the Russian-made air defenses in Venezuela’s possession managed to shoot down a single plane American during the operation, despite the fact that the country had on paper respectable systems such as S-300VM, Buk-M2, Pantsir-S1 and radars of Russian and Chinese origin. The image of airspace simply collapsing under a well-planned operation It has been devastating from a symbolic point of view, because it shows that having advanced systems does not guarantee their effectiveness if they are overcome by a combination of surprise, electronic warfare, stealth and multi-domain coordination. 9A83ME launcher of the S-300VM Antey-2500 missile system Not everything is the system. The Venezuelan failure cannot be explained solely by the technical limitations of the Russian systems, but also due to structural factors such as the state of maintenance, the real integration of the defense network, the quality of command and control and, above all, the training and experience of the operators. An anti-aircraft system is only as effective as the doctrine that supports it and the people who operate it, and in Caracas it became clear that, in the face of a well-trained Western force, even feared equipment can be defeated. reduced to passive spectators if they do not function as part of a coherent whole. Repeating pattern. What happened in Venezuela is not an isolated case, but rather fits with a pattern observed in other scenarios like syria or attacks Israelis against Iranwhere air defenses of Russian origin have shown irregular performance against forces that master electronic warfare and stealth. Although in Ukraine, operated directly by Russia, these defenses have worked betterhave also not achieved the invulnerability that their reputation promised, which reinforces the idea that their effectiveness decreases considerably when faced with adversaries capable of combining interference, cyberattacks, deception and precision attacks. Without triumphalism. There is no doubt, for the United States, about the Caracas operation strengthens confidence in its ability to penetrate airspace defended by Russian systems, but it also emphasizes that this success depends on exhaustive planning and intensive use of invisible capabilities that are not improvised. The lesson is not so much that Russian defenses are useless, but that in the face of an adversary that dominates the electromagnetic spectrumEven feared systems can be neutralized long enough for a decisive operation to take place. The war that is not seen. If you also want, the assault on Caracas leaves an uncomfortable and increasingly obvious conclusion: modern war is decided before the first shotin an intangible space made of signals, links and frequencies, where whoever controls the information controls the result. He Growler He did not fire a single bullet, but its effect It was more devastating than that of many bombs, remembering that in current conflicts lose seeing and hearing is almost always equivalent to losing the war before it begins.

The United States has turned Trinidad and Tobago into the war container it was missing. Venezuela has responded like Russia: an invisible fleet

by

The conflict between the United States and Venezuela has entered a phase in which the silent accumulation media outweighs official statements. If you will, the Caribbean once again functions as a strategic belt from which Washington projects pressure without the need to declare an open war. Under the formal argument of the fight against drug trafficking, the White House has been weaving a support network logistics, radars, airstrips, ports and resupply spaces in an arc at a time bigger of “allies”. The Venezuela’s response We already saw it in Russia. The map of countries. That “arc” of allies Washington runs from the Dominican Republic to Trinidad and Tobago, passing through Aruba, Curaçao, Bonaire, Grenada, Puerto Rico and the Virgin Islands. The deployment includes destroyers, nuclear submarines, amphibious ships, aircraft carriers, state-of-the-art fighters, drones and thousands of troops, not enough for a land invasion, but enough to control air and maritime space, monitor critical routes and sustain missile attacks if it is decided to escalate. It is a prepositioning strategy classic: being everywhere without publicly assuming that something else is in the works. Trinidad and Tobago, the most sensitive link. Within that architecture, Trinidad and Tobago emerges as the most delicate piece of the board. Its extreme proximity to the Venezuelan coast turns any gesture into a political and military message. The new government has authorized the use of its airports by US military aircraft, has received warships and marine units, has allowed joint exercises and has accepted the installation of an AN/TPS-80 G/ATOR radar capable of detecting aircraft, drones and missiles. Everything is presented as logistical and defensive cooperationbut it fits almost literally with the US National Security Strategy of 2025, which calls for a toughened version of the Monroe Doctrine to reaffirm the preeminence of the United States in the Western Hemisphere and prevent external actors from controlling strategic assets. Trinidad and Tobago insist in that it will not be a platform for offensive attacks except direct aggression, but its role as node of surveillance, resupply and intelligence places it at the center of any scenario of sustained pressure on Caracas. A blockage that is not. The announced threat by Trump of a “total and complete” interdiction of sanctioned oil tankers entering or leaving Venezuela fits into that model of gradual pressure. It is not about closing ports with a formal declaration of war, but about taking advantage of naval and air superiority, supported by friendly infrastructure, to intercept, seize or deter the ships that support the main source of income for the Nicolás Maduro regime. The recent seizure of an oil tanker loaded with nearly two million barrels and the warning that further action could follow shows the extent to which Washington is willing to take pressure beyond the symbolic, taking the risk of controlled incidents in international waters. The Venezuelan response. Faced with this siege, Caracas has reacted by raising the profile of its challenge. The order to escort ships that transport oil products and derivatives to Asia is a calculated move: it seeks to demonstrate that the Venezuelan State does not renounce its right to free navigation and that it is willing to involve to his Navy to keep exports open. It is also a response that increases the risk of confrontationbut that sends an internal and external message of resistance. Oil continues to be the financial pillar of the regime, and losing it would be equivalent to accepting total economic asphyxiation. The ghost fleets. Beyond the visible escort, the true backbone of the Venezuelan strategy is the ghost fleeta tactic practically copied from the used by Russia after Western sanctions. Old oil tankers, many with more than twenty or thirty years of service, change name and flagsteal the identities of already dismantled ships, sail under flags of convenience, turn off or manipulate their identification systems and carry out crude oil transfers on the high seas to hide the origin of the cargo. The result is an opaque trade that allows you to sell oil with large discounts to buyers willing to take risks, while the traceability required by sanctions is diluted. It is not a marginal phenomenon: a significant part of the world’s oil tanker fleet already operates in this gray ecosystem, transporting Venezuelan, Russian or Iranian crude. Sanctions that do not suffocate, they deform. The BBC reported that the data show that, although far from the historical levels of the end of the 20th century, Venezuelan exports have recovered notably compared to the collapse of 2019. This indicates that the sanctions have not paralyzed the flow, but rather have displaced it towards more opaque and risky circuits. As in the Russian caseeconomic punishment does not eliminate trade, it makes it more expensive, makes it less transparent and reinforces dependence on informal networks and actors willing to move illegally. The Caribbean as a conflict. With US aircraft carriers patrolling the Caribbean, radars deployed in islands near Venezuela and escorted or invisible tankers sailing to Asiathe conflict is located in a dangerous intermediate zone between economic pressure and military confrontation. The United States bets on the ccontrol of space and logistics regional via of discreet allieswhile Venezuela responds with the same manual that has allowed other sanctioned countries to survive: ghost fleets, aggressive discounts and specific shows of force. The Caribbean, for decades associated with tourism and trade, is thus once again a scene of high geopolitical tension where each radar installed and each oil tanker intercepted brings the risk of a clash that no one admits they want, but for which both sides seem to prepare, a little closer.

An “invisible” Russian submarine has set off alarms in the Arctic. Europe’s response: Atlantic Bastion

by

The launching of the Khabarovskthe new and ultra-quiet Russian submarine capable of deploying nuclear torpedoes Poseidonhas reactivated a fear that had been latent for decades in cities like London: the possibility that the naval balance of the Atlantic is once again tilting in favor of Moscow. The response from the United Kingdom has been forceful, and it is called Atlantic Bastion. Submarine warfare. Although the public image of the Russian threat usually revolves around research vessels like Yantarsuspected of mapping and potentially manipulating underwater cables and pipes, European specialists know that what is truly disturbing lies much further down. Russia has spent decades reducing the acoustic signature of its submarines to levels that they border on invisibilitycombining new propulsion systems, composite coatings and virtually undetectable cooling pumps. In this environment, where silence is power, a ghost submarine with nuclear capacity alters not only the sea routes, but the very heart of the strategic infrastructures that connect Europe with the world. UK reinvents itself. Faced with the resurgent threat from Khabarovskthe Royal Navy has launched what they have called as Atlantic Bastiona plan designed to restore British strategic advantage in its own and allied waters. Its origin is not new and it we have counted before: the United Kingdom has been monitoring the Greenland-Iceland-United Kingdom gap (GIUK gap) since before the creation of NATO, and the Second World War already demonstrated that controlling that maritime corridor was essential to prevent enemy forces from slipping into the North Atlantic. But what used to be destroyers and acoustic sweeps is becoming a hybrid framework that combines Type 26 frigates equipped with new generation sonar, aircraft P-8 Poseidon capable of patrolling thousands of kilometers and, above all, swarms of underwater drones equipped with artificial intelligence. According to the Ministry of Defensethis architecture aims to detect, classify and follow any enemy submarine that tries to penetrate British or Irish waters, and to do so constantly, autonomously and with an unprecedented range. The algorithms arrive. The core of the project will be Atlantic Neta distributed network of autonomous underwater gliders equipped with acoustic sensors and guided by artificial intelligence systems capable of recognize sound signatures with a level of precision that until a few years ago was little less than the preserve of science fiction. Unlike the SOSUS of the Cold War, based on gigantic fixed hydrophones placed on the seabed, the new generation will be mobile, expandable and adaptable to the routes and behaviors of increasingly soundproof submarines. The ultimate ambition is to deploy hundreds of cheap, persistent units that together create aa surveillance mesh much harder to evade. The metaphor is revealing: if finding a silent submarine is like searching for a needle in an oceanic haystack, modern technology makes it possible to exponentially multiply the number of searching hands. Khabarovk The technological challenge of hunting shadows. However, even with this technological revolution, experts warn that detecting new Russian submarines will continue to be an extremely complex undertaking. Since the 1980s, Moscow has drastically reduced lacoustic emissions of its fleet, which requires combining passive and active sensors and complex configurations such as bistatic sonar, where one vessel emits a pulse and another collects the echo. These techniques require coordination, multiple platforms, and significant sensor density, something that Atlantic Bastionaims to provide but it is still far from being deployed on a full scale. The arrival of the Type 26 frigates, designed to be the flagship of British anti-submarine warfare, is fundamental to this purpose, as is the cooperation with Norway and other allies that are also strengthening their capabilities in the North Atlantic. The Russian Bastion Puzzle. Even if Atlantic Bastion managed to limit the presence of Russian attack submarines in the Atlantic, there is one dimension that no Western system can solve: Russian strategic submarines already they don’t need to abandon its own bastion in the Arctic to threaten Europe or the United States. Its intercontinental ballistic missiles can hit targets thousands of kilometers without moving from the Barents Sea or the White Sea, protected by layers of defenses and favorable geographical conditions. There they play a hiding place lethal where the West cannot penetrate without significantly escalating the conflict. The paradox is clear: the United Kingdom can reinforce its waters and monitor every meter of the GIUK gapbut it cannot deny the Russian nuclear capacity deployed in its natural refuge, a reality that frames the entire British effort within a logic of containment rather than domination. An underwater chess. If you want, Atlantic Bastion ultimately represents the recognition that underwater competition has returned with a vengeance, now fueled for digital capabilitiesdistributed sensors and autonomous platforms that transform the nature of ocean surveillance. The North Atlantic once again becomes a stage silent maneuvers where Russia and the United Kingdom measure their technological resistance in an environment reminiscent of the Cold War, but with algorithms and autonomy as new weapons. A career that is not decided by great battles, but by the ability to listen better, process faster and anticipate invisible movements. In this theater of shadows, the advantage is not whoever shoots the most, but rather whoever is able to detect first (already happens in Ukraine). Thus, Atlantic Bastion aspires to return that capacity to the British, although the contest that is opening now does not look like it will be brief nor simple: In the depths of the Atlantic, the prelude to the next era of strategic rivalry between Russia and the West is underway.

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.

appears out of nowhere and turns Russia invisible

by

At the beginning of November a scene It went viral on networks. The arrival of Russian troops in Pokrovs was more typical of a dystopia, another example that the war in Ukraine seemed to have definitively become a mirror of what the war conflicts of the future will be like. Now we know that that scene was also the prelude to an advantage. The weather in front. Yes, on the eastern lines of Ukraine, the arrival of a winter full of dense fogs has transformed the battlefield in an unpredictable scenario where visibility, which previously determined the pace of drones, has become a strategic resource in itself. The veil of humidity that covers Donetsk, Zaporizhzhia and the approaches to Pokrovsk It makes the job of Ukrainian operators who rely on aerial surveillance to track Russian movements, but also offers an opportunity to sneak up, infiltrate and strike at close range. The chaos. In areas like Pokrovskwhere the lines overlap and the front is porous, the fog has caused a kind of calculated chaos that makes war unpredictable, a board where both armies move almost groping between bursts of fire that appear without warning, while the commanders admit that the weather is completely altering the reading of the terrain and the control of the approaches. Exploiting meteorological disorder. The fog has allowed Russian forces to promote specific advances and risky maneuvers. Taking advantage of the lack of aerial surveillance, mechanized units have managed to cross natural obstacles, build improvised bridges and make their way into areas where they were previously stopped by constant reconnaissance from the air. In southern regions, such as Zaporizhzhia and Dnipropetrovsklow visibility has coincided with an increase in assaults and intensive bombing that has forced Ukraine to retreat from certain positions in search of more sustainable defensive lines. The accumulation of troops under the cover of fog, the concentration of armored vehicles and the constant infiltrations by small teams seeking to advance without being detected reflect a strategy that combines quantity, continuous pressure and meteorological opportunism. At the same time, the movement of columns towards towns such as Huliaipole and Yablukove confirms that Russia tries to convert each weather window into a territorial advance, aware that controlling logistics nodes at this time of year can set the trend for the entire campaign. Solution: ground robots. Faced with the temporary loss of eyes in the sky, Ukraine has begun to integrate ground robotic systems to replace the surveillance that drones previously guaranteed. The appearance of UGVs In the defense of Pokrovsk it has made it possible to detect enemy movements that would have gone unnoticed in the dense fog and has served to guide subsequent attacks with FPV drones when visibility permitted. These small, discreet and fast platforms have provided an additional layer reconnaissance in areas where even the best aerial optics fail. Its deployment shows that the Ukrainian army is maturing hybrid doctrines where ground robots complete the work of drones that they previously dominated alone. If you will, it’s a preview of how technological warfare could evolve in the coming years: closer integration between autonomous ground sensors and aerial vectors, especially in adverse climates that are becoming more frequent and extreme. Units operating in Pokrovsk describe combat scenes where attacks emerge from the fogguided by machines that detect heat, sound or movement in conditions in which the human eye is practically blind. The pressure on Pokrovsk. The worsening of the weather coincides with a deterioration of the tactical situation in Pokrovska critical point due to its value as a transport hub and link for the defense of the east. Russia has intensified assaults relying both on climate coverage and on a notable numerical imbalance that favors its troops. Ukrainian forces acknowledge that they face waves of infantry in very small groups, teams of two or three soldiers seeking to saturate the defenses through multiple approaches, and that the fog has facilitated the temporary return of mechanized assaultseven using civilian vehicles to advance quickly in the direction of the city. A plan B. This dynamic has forced Ukraine to combine tactical withdrawals, civilian evacuations and robotic ground reconnaissance to avoid surprises. The adverse weather has accelerated the feeling of uncertainty on a front where every meter of ground is contested blindly and where the lack of aerial vision multiplies the risk that an enemy leak becomes an operational rupture. Time changes everything. The combination of persistent fog, limited mobility and low visibility has created a combat ecosystem that rewards both creativity and audacity. In this environment, the infiltration tactics Russians find more room to thrive, but so do quick Ukrainian incursions that seek to disorient the adversary in the chaos of the fog. Climate has become a multiplier of uncertainty: it degrades the precision of drones, distorts sensors, creates gaps in surveillance and pushes both sides to improvise technological and tactical solutions. Ukrainian ground robots represent a popup response to those conditions, while Russian advances under adverse weather show the importance Moscow attaches at any opportunity to break the Ukrainian defense.

a poncho turns its soldiers in Ukraine into an invisible army

Last October Ukraine I remembered to his troops that Russian soldiers had come up with a new infiltration system. After the helmets with antennathe lures and the optical illusionsMoscow had found a way to appear among the Ukrainian forces “out of nowhere”. Now, in a new unprecedented twist in the conflict, Russia has found the closest thing to an invisibility shield. From the video game to the fight. Something very similar to what we saw in the Metal Gear saga, then called optical camouflagehas appeared in the conflict in Europe. The war on the Russian-Ukrainian front has seen a tactical evolution that has shifted classic protection (armor and vehicles) towards mobility and thermal stealth: Russian assault forces have adopted ponchos or thermal tarps (the so-called “invisibility cloaks”) as an essential element to minimize the infrared signature and allow infiltrations on foot in the wide swath controlled by the drones. There is no perfect thermal concealment, but the difference between being detected or not can decide the life of an assault group. That’s why these clothes, combined with night movements and the use of specific environmental conditions, have become a central tactical tool that, in practice, today protects more than many armored vehicles against the aerial threat of reconnaissance and attack. Tactical evolution. Thermal tarps are blankets made with reflective layers and materials that accelerate heat dissipation, their purpose is approximate the temperature superficial of the human body to that of the environment to reduce contrast that thermal cameras detect. However, its effectiveness depends of multiple factors: quality of the material, contour sealing (bare feet and hands are detectable signs), weather conditions and, above all, the time of day. The so-called as “thermal crossover” (two brief daily periods in which vegetation, soil and air have similar temperatures) reduces global thermal contrast and offers the optimal window to move forward without standing out, while fog, rain or humidity can complement that invisibility. Improperly used, ponchos generate “cold spots” that attract attentionbut used well, multiply the probability of achieving tactical objectives. Limitations and learning. It must be clarified that thermal tarps do not make the attacker invulnerable. Experienced drone operators look for subtle signs (bare feet, movement under the cover, small thermal disturbances) and learn to distinguish behavioral patterns that reveal infiltrations. In addition, there are low quality materials and training errors: there are cases of soldiers who tried to camouflage themselves in broad daylight or with inappropriate ponchos and were detected. The tactic is therefore effective but fragile: it works best en masse, under optimal conditions and when the adversary lacks sufficient alternative sensors or personnel on the line. US Marine Corps uniform with built-in thermal camouflage Countermeasures and tactical recovery. To counteract these infiltrations, the solution it is not unique: involves deploying complementary sensors (acoustic, magnetic, seismic) that do not depend on the thermal spectrum, or reinforcing minefields and physical barriers, densifying human or robotic presence in exposed sectors, or even improving doctrine multisensory surveillance and train detection teams to identify minimal signs of intrusion. In strategic terms, Ukrainian forces agree that the response involves combining technology (more sensors, better integration) with greater territorial occupation, because passive defense based solely in aerial interceptions It is insufficient against equipment that infiltrates at low visibility. Operational implications. The resort to small infiltrated groups reflects broader tensions: troop shortages, accumulated material wear and tear, and an environment where air or drone superiority does not guarantee the security of the rear. For those who attack, the tactics allows you to exploit holes in defense and wear down positions through groups that, although they lose part of their troops, can complete reconnaissance, sabotage or local assault missions. For those who defend it, it forces us to rethink the segmentation of the front and the provision of resources: the balance between expensive sensors and effective personnel, the need for mobile reserves and the growing importance of passive and active containment measures on the ground. Strategic conclusion. If you like, we are facing a tactical transformation where war becomes more granular and less dependent on traditional armor: the multiplication of drones and sensors has revalued thermal invisibility and human mobility, while it has revealed the fragility of conventional defensive schemes. In the short term, the balance favors those who know integrate camouflagemeteorology and discreet logistics. In the medium term, effective defense will require a greater density of heterogeneous sensors, more troops or robotic means on the line and a doctrinal adaptation that combines multisensory detection with physical measures that close the gaps that infiltrators exploit today. In short, in the current field a thermal tarpwell used, can offer an attacker more practical protection than many armored vehicles, and this realization forces us to rethink tactical defense and territory management in a conflict dominated by sensor warfare.

We always believed that the light guns fired invisible rays, but the reality is the opposite: it was the TV that shot

Recognize it: if you are old enough to have played withA Light GunFor a while you thought that this gadget worked by firing rays of invisible light that television detected. Was it the position of the gun? The distance? Did the glass of the screen really knew when the goal was in front? Actually the solution was much simpler and ingenious. The light ray is in reverse: the gun is the receiver. Guns of what. First, let’s remember the history of the device: the light guns in video games began to appear in the thirties in mechanical arcades and evolved towards electronic video games in the 1970s and 1980s. Nintendo already experimented with early versions with its video shooting series for famicom in 1984, whose gun was not futuristic, but it seemed like a western revolver With the theme of the game. Nintendo arrives. The device of this most popular type was Nintendo Zapper for Nespossibly because he was accompanied by one of the most iconic games of the genre, ‘Duck hunt’. The Zapper was already tumbos since 1984 with the version for Famicom, but in 1985 it became the Zapper of NES and left in the United States with the science fiction design we know, automatically becoming a pop icon. In 1988 it was redesigned with bright colors to resemble even less to a real weapon and comply with the legislation. There were up to 17 official games for Zapper. In Xataka This genius has transformed the ZNA Zapper is an incredible laser ray gun But … how did it work? Actually the Zapper and the rest of the light guns of the time were not emitters, but light receptors. The process that followed to work was: when the player clenched a trigger, the screen turned black during a Frame. In the following, the objects to which they have to become white blocks, and the rest remains black. The human eye can barely distinguish this pair of Frames Inside the gun was a light sensor that detected if the area to which it was aimed had changed to Blanco. The game determined what objective had been “shot” according to the time in which this white block appeared, since each white objective was sequentially shown in a different frame. And of course, if the sensor detected the white light inside the expected interval, the shot was counted as a success. Only for old people. The ingenious method only worked on CRT screens, as technology depended completely on the speed and characteristics (on the shortcomings, let’s go) on the soda speed of the cathodic tube. On LCD screens, plasmas and other modernities, the delay changes, and so does the soda technology. What makes ancient games “rare” on modern televisions is also what prevents the gun sensor from correctly capturing the light and location of whites. {“Videid”: “X9HMC3A”, “Autoplay”: False, “Title”: “Nes Mini, Review and Spanish analysis”, “Tag”: “”, “Duration”: “250”} More guns. Then, especially in the field of recreational, more sophisticated guns arrived, such as ‘Operation Wolf’, which was actually a command that determined where it pointed according to the position of the gun, fixed in the machine of the machine (a method as ingenious as that of the Zapper, playing with what the player who is happening is believed). And then they arrived, in fact they do in machines that remain in operation, increasingly sophisticated systems, and that use infrared sensors or cameras to determine where the player points out. But the adorable imagination and naivety of the Zapper give him a unique personality.
