the Ukrainian drone that stopped Russia for six weeks with a machine gun and not a single human soldier

On the Ukrainian front, where every meter conquered or defended is paid for with a human cost that is increasingly difficult to assume, ingenuity is has become a resource as valuable as ammunition. In this context of extreme wear and constant adaptation, some units are experimenting with little visible solutions that, without attracting attention, are beginning to change the way a battle line is held. When there are no soldiers left. In a war marked by a shortage of infantry and the extreme lethality of maintaining forward positions, Ukraine has begun to test a solution that until recently belonged to military science fiction: leaving the front in machine hands. During 45 consecutive daysa Ukrainian unit maintained front-line sectors without direct human presence, entrusting the defense to a single land vehicle unmanned, a bet that summarizes the crude logic of the current conflict: if something can receive enemy fire, it better not bleed. The doctrine. The experience was reported by the NC-13 Strike Company, integrated into the Third Corps of the Ukrainian Army, a unit created specifically to operate unmanned ground vehicles. Its commander, Mykola “Makar” Zinkevych, explained that the idea was radically simple: “robots don’t bleed,” and the ground drone was the only element present in the position, carrying out constant suppressive fire missions to deter Russian advances and force the enemy to confront a defense that could not be psychologically worn down or eliminated with human casualties. The droid TW 12.7. The system used was the Droid TW 12.7developed by the Ukrainian company DevDroida small tracked vehicle armed with a heavy machine gun M2 Browning .50 caliber. Far from being an isolated prototype, the drone was displaced between different positions at the request of local command posts, acting as a mobile punishment platform that turned each attempted Russian advance into a costly and risky operation. The Droid TW 12.7 Wear and tear… also for machines. Although the robot could remain in place for days, it needed withdraw every 48 hours for maintenance, resupply of ammunition and recharging of batteries, tasks carried out by a team located several kilometers from the front. The process, initially four hours, is reduced by half thanks to the purchase of additional batteries paid for by the soldiers themselves, a detail that illustrates the extent to which the Ukrainian war continues to depend on local initiatives and improvised financing even when talking about advanced technology. Limited autonomy. DevDroid affirms that the Droid TW 12.7 can operate at distances of up to 15 miles and has artificial intelligence-assisted navigation functions, although it is unclear to what extent it can act autonomously in combat. Even so, the simple fact that a single UGV has held positions for six weeks demonstrates that the value of these systems lies not only in their sophistication, but in their ability to replace human bodies in tasks where survival is minimal. From experiment to military doctrine. After this experience, the Zinkevych unit plans to expand the use of UGVs in both defensive and offensive missions, relying on new variants equipped with grenade launchers already approved for official use. The demand, recognizeis very high, but so are the costs, to the point that development continues to be partially financed through crowdfunding campaigns. The future of the front. If you like, the case Droid TW 12.7 It is not just a technological anecdote, but a sign of where to go war is headed modern in Ukraine: a battlefield where every meter can be defended with sensors, steel and algorithms instead of flesh and blood, and where the strategic value of a soldier begins to also be measured by his ability not to be physically there.

The drone war in Ukraine is advancing at the speed of light: what was useful two weeks ago is a death trap today

Since the first months of the Russian invasion, Ukraine has converted the use of drones in one of the central pillars of its defense, and has done so to the point of transforming a conventional conflict into a permanent laboratory unmanned combat. In this environment of constant adaptation, drones have not only redefined the way we fight on the front, but have imposed an unprecedented pace of technological change that forces armies, industries and training centers to update almost in real time to avoid becoming obsolete. Classrooms at war. The Ukrainian drone schools have become one of the most extreme laboratories of military learning in the world, forced to rewrite their training programs at a dizzying pace that in some cases reaches the two weeks. In a conflict where drones have become the main instrument of attack, reconnaissance and attrition, the distance between an obsolete lesson and a lethal decision can be measured in days. For these centers, adapting is not an academic question, but rather a direct line between survival and death on the front, in an environment where technology, countermeasures and tactics change constantly and rapidly. In Xataka We had seen everything in Ukraine, but this is new: drones are disguising themselves as Russian soldiers, and it is working Synergy. To stay relevant, instructors are not limited to manuals or simulators. They regularly visit the battle lines, maintain permanent contact with alumni deployed and testing new technologies before incorporating them into their courses. In schools like Dronarium, with offices in kyiv and Lviv, its R&D manager, the veteran known as “Ruda”, explains that technological evolution on the front is so rapid that it requires almost immediate adaptability. There is no two equal classes: Each lesson incorporates small adjustments resulting from what happened days before in real combat. More than 16,000 students have passed through this center, and their experiences are directly integrated into the curriculum, turning training into a living system that feeds back on the war. Two-way learning. One of the pillars of this model is communication direct and permanent with the combatants. Messaging groups connect deployed instructors and operators, allowing soldiers to share new enemy tactics, technical problems or improvised solutions, while receiving advice in near real time from the rear. In centers like Karlsson, Karas & Associates or Kruk Drones, this relationship does not end at the end of the course: it is maintained throughout the operator’s operational life. The instruction is clear: nothing is taught that is not strictly necessary in combat, and what is no longer useful is unceremoniously discarded, no matter how recent it may be. A war that reinvents itself. The central weight of drones on the battlefield explains this urgency. The majority of frontline impacts and casualties already depend on unmanned systems, requiring continuous modification of both platforms and employment tactics. New models appear, others are neutralized by countermeasures, and the rules of the game are constantly rewritten. This speed has set off alarm bells in the West: military officials such as British Minister Luke Pollard warn that NATO forces run the risk of becoming obsolete, trapped in acquisition cycles that last years in the face of a war that repeats every two or three weeks. {“videoId”:”x8j6422″,”autoplay”:false,”title”:”Declassified video of the clash between Russian fighters and the American drone”, “tag”:”united states”, “duration”:”42″} The industry learns from Ukraine. The schools they are not alone in this race. Defense companies that observe the conflict have begun to copy this model of direct interaction with the front, shortening your cycles developmental. Manufacturers of anti-drone systems and UAV platforms visit the battlefield, chat with operators and fine-tune designs in a matter of weeks, not years. Some executives recognize that the ways in which Ukrainians use technology have surprised them, forcing them to rethink basic assumptions. At the same time, the soldiers themselves benefit from this exchange, providing constant feedback and receiving improvements, spare parts and solutions adapted to their real needs. In Genbeta According to psychology, those who grew up in the 1960s and 1970s developed mental strengths that are being lost today Schools under fire. There is no doubt, this permanent adaptation has a cost. Drone schools are not only competing against the technological clock, they are operating under the direct threat from Russian attacks and with limited financial resources, often depending on donations to continue functioning. In this context, their fight is not only to stay updated, but to survive. Even so, their role has become central in modern warfare: they are the link that connects innovation, industry and real combat, and the best example of how Ukraine has turned the urgency of conflict into a flexible and brutally efficient national military learning system.

We have had Stephen King releases for several weeks in a row. Don’t we know how to do anything else?

The fall of 2025 has brought with it an avalanche of Stephen King: almost in consecutive weeks we have had the premiere of ‘The long march‘ and ‘The Running Man‘, and shortly before the series started ‘It: Welcome to Derry‘ on HBO Max. Three great productions in just one month. Are we facing an unimaginative industry that constantly turns to the same author, or is it that King continues to offer something that others cannot? The answer has three keys: the so-called Kingaissance, the decisive factor of the streaming and the current value of King, which has not been devalued by bad adaptations. Debunking the myth. To deny King’s supposed dependence on the horror genre, just look at the last twelve months of releases. Independent horror is enjoying an unsuspected golden age: ‘Longlegs’, for example, grossed more than one hundred million dollars at the box office with a budget of just ten, and films like ‘The substance‘ have given terror a life-long breath of quality, including Oscar nominations. Classic franchises such as ‘Final Destination’ are recovered, ‘Frankenstein’ is sweeping Netflix and a star system from horror creators: the aforementioned Perkins, Prano Bailey-Bond, Danny and Michael Philippou, Zach Creggar and Rose Glass, among others. The Kingaissance. The Anglo-Saxon media coined a term to describe what is happening: the “Kingaissance“, a revival that has a precise birth date. In September 2017, ‘It’ by Andy Muschietti became an unexpected cultural phenomenon: With a budget of just thirty-five million, it grossed more than seven hundred globally, becoming the highest-grossing horror film in history without adjusting for inflation. What followed was an avalanche. Without exhaustiveness: ‘Doctor Sleep’, ‘Animal Graveyard’, ‘Eyes of Fire’, ‘Salem’s Lot’, ‘In the Tall Grass’, the series ‘Apocalypse’ and ‘Chapelwaite’… And now, three more adaptations, to which will be added the future television ‘Carrie’ by Mike Flanagan, ‘The Talisman’ for Netflix and perhaps a new ‘Cujo’. The difference with the eighties is abysmal. Back then, TV movies and B series predominated: now they are series on HBO and films with established directors. King himself often has creative control and serves as executive producer on many of these projects. The factor streaming. For decades, adaptations of King’s longer novels have been handicapped by having to compress their length to the margins of the feature film. He streaming changed the rules of the game: platforms now allow series of eight or ten episodes that respect the author’s narrative complexity, something that had previously only been experienced in miniseries format, in productions such as the first version of ‘It’ or ‘The Store’. It happened with ‘11.22.63’, with ‘The Stranger’, with ‘Lisey’s Story’ (which King personally wrote)… Now it is the turn of the prequel to the latest version of ‘It’, and it is clear how the logic of the platforms works: they look for recognizable IPs, and King offers dozens of stories with a bomb-proof dramatic structure. But there were bad adaptations of King. And they didn’t kill the goose that laid the golden eggs. It’s always happened: there are adaptations in miniseries format in the nineties, like ‘The Langoliers’ or ‘The Shining’ that are a pain. Since the nineties there have been as many weak King films as there have been notable ones. Very recent is the horrendous ‘The Dark Tower’ from 2017, which compressed eight novels into 95 disastrous minutes. Or ‘Cell’, absolutely forgettable. Why didn’t these catastrophes sink King’s value? First, the original novels remain, at worst, more than readable, and at best, downright excellent: the source material is indestructible. Second, readers clearly distinguish between author and adaptation, continue to appreciate the writer, and continue to try their hand at adaptations. Third, the good adaptations (‘The Shining,’ ‘Carrie,’ ‘It,’ ‘Misery,’ the original ‘Pet Sematary’) are so good that we’ll always come back for more. Why we return to King. The answer, despite appearances, is not a lack of ideas, but rather that we are faced with a name of proven effectiveness, even in its worst moments: few have that commercial hook combined with minimum standards of quality and entertainment. King has more than 65 novels and 200 short stories, an inexhaustible mine whose themes will never go out of style and are universal: generational traumas, addictions, the problems of the working class, invisible threats, the corruption of power, the weight of our past… And to top it off, we are in the era of the IP. So it is not an issue that affects only him. Marvel, DC, Disney… In 2024, the ten highest-grossing films They all came from pre-existing intellectual properties. And Hollywood seeks familiarity: from the Agatha Christie films directed by Kenneth Branagh to the explosion of video game adaptations like ‘fallout‘, ‘The Last of Us‘ and ‘Super Mario Bros.: The Movie‘. An ideal scenario for a brand that, undoubtedly, has had its ups and downs, but that right now enjoys unexpected iron health.

thermal lurches have weeks left

Suddenly and without warning, the cold has crept into Spain. More than half the country is waking up with temperatures close to zero And, although it is true that the afternoons are still mild, millions of people are faced with the big question of the moment: is it time to change clothes? Or what is the same, translated into meteorological terms, is the cold here to stay? What has happened? In reality, it is not so much what has happened, but what is happening and what is going to happen. Because in the coming days, we are going to see very rapid temperature jumps (“from ice to sun in 48 hours“, with increases and subsequent decreases). We have already seen it: Ciudad Real went from a minimum of 13 to a minimum of 5 from one day to the next. Teruel, Salamanca or Palencia dropped below zero degrees. And, although in the abstract it is not strange that as we approach November the days are increasingly colder, the heat is holding so much so that the “saw teeth” are much more pronounced. Temperature changes are so marked that they are no longer just meteorological curiosities: they are causing problems in people’s daily lives. Is it going to continue like this? This is interesting. According to AEMETNovember is going to be relatively warm at least during the first fortnight. Warm anomalies and above-average precipitation. However, the ECMWF suggests That’s where the “heat” ends. To that first fortnight with thermal values ​​still above average and strong Atlantic circulation (i.e., more generous rainfall on the western slope); It seems that a second half of November will follow in which a possible pattern change will bring more normalized temperatures. Because? On a technical level, what we are seeing is the product of an alternation of warm ridges and cold fronts. We are talking about mild days, open skies and thermal rises, followed by abrupt drops as cooler maritime air enters. What does all this translate into? In a very pronounced thermal variability. That is to say, a heightened risk of isolated frosts in the interior despite the fact that the days are mild and pleasant. This will have strong impacts in agriculture (especially stone fruits and autumn products), in energy demand (at such an uncertain time) and health (the early arrival of respiratory infections). All this punctuated by a series of Atlantic storms that will repeatedly impact the west; while the Mediterranean will be relatively calm with probable scares against DANAs or undulations of the jet stream. So, is the cold here to stay? In the short term, no. The models point to a soft first half of November compared to the average, with occasional declines. The stable cold seems to be delayed until the second half of November. Image | Tomer Burg In Xataka | A group of researchers is trapped in an Antarctic base under a threat: that of one of them.

I have measured the CO2 of my office for weeks. And now religiously vento every hour and a half

I’ve spent a few weeks trying The Netatmo Meteorological Station In my office, a ten -square -meter cubicle where the workday passed. August in Valencia is brutal: 35 degrees and 75% moisture at noon are normal values. But what I really wanted to verify was not the temperature or moisture. It was the CO2 concentration. The first Monday I started curious. At 8:05 a.m., with an open window and door since Friday, the sensor marked 438 ppm, atmospheric level. I started working. At 9:30 a.m., 455 ppm, minimum increase. Then I closed door and window to simulate winter conditions. Effects of CO2 concentration on the environment. Image: Vobu. At thirty minutes: 802 ppm. An hour later: almost 1,400 ppm. A little later: more than 1,600 ppm. Had already begun to notice That characteristic mental fatigue, that heaviness That a few days blame for fatigue. That inability to do well what you usually do well, mixed with apathy. It is not placebo, there are plenty of studies that support it. As Este de Harvard and Syracuse of 2015: The levels between 1,000 and 2,500 ppm – manner in offices – reduce up to 15% the yield in complex cognitive tasks. In decision -making, Hasdta 23%. I opened the window but not the door. The CO2 dropped from 1,600 to 800 ppm in 25 minutes. The next day, with cross current: same descent in 12 minutes. Half. A difference that did not expect so marked. In a short time, the level returned to 450 ppm. Graph of the Netatmo application during one of the tests: all night with the empty office, beginning of the morning working with everything open. I closed door and window. And when I reached the peak of almost 1,600 ppm, I opened back and window. And the fall was even faster than the climb. Image: Xataka. This shows the Netatmo app interface the CO2 concentration, visually indicating its condition, along with other values. Image: Xataka. Another test. Only opening door or window, the fall is slower than if we open both to create a current. Something we know always, but now we can quantify and assume with greater awareness. Image: Xataka. Netatmo has an error margin of ± 100 ppm up to 1,000 ppm, ± 10% above. It is not laboratory precision, but to understand your home it serves. The important thing is not the exact number but the evolution and its correlation with how you feel. With the passing of the days, varying openings and closures, I began to detect patterns. Ventilating more frequently than usual, sporadic apathy and mental mist. They are directly correlated with air renewal. Which takes me to the next point: The air conditioning. I sensed that I would not improve the concentration of CO2. Indeed: the air moves and cools, but does not renew it. Purifiers would not help except that they have outdoor entrance. They filter particles, do not eliminate gases such as carbon dioxide. When looking at the graph in more detail it is easy to see that by a lot of ventilation and current that there is, a human breathing inevitably increases the concentration of CO2 in the stay, and in a cumulative way. Although within the appropriate values. Around 6:00 h entered a few minutes (climb), I left shortly (low) and then returned to spend the whole morning (go up) until I went to eat (low). As if he had a presence detector. Image: Xataka. Image: Xataka. I brought the netatm to bedroom. Two people sleeping with a closed window and open door: CO2 rose from 450 to 1,100 ppm. Heavy awakening, feeling of not having rested. Next night with open window: maximum 640 ppm. I woke up remarkably clearer. He has convinced me to sleep with open window even in winter. The station measures more: interior/exterior temperature (with the separate module), humidity, barometric pressure, noise. It is expandable with pluviometer and anemometer. Elegant app, indefinite historical, integration Homekit flawless. But living vertically and without garden, for me the real value is in CO2. On the integration with homekit: when CO2 went from 1,100 ppm, this notification reached me in Mac (image) and iPhone. Image: Xataka. And notification on the iPhone. Image: Xataka. I have learned that working with more than 1,000 ppm is to function at 70% cognitive. The problem: do not notice immediately. Like that second cup that you think harmless until you try to add the head account. Now a lot more. Permanently open windows or, when time prevents it, more frequent openings than before. Do you justify 110 euros This learning? If you work in closed spaces, yes. Not for the apparatus, but for the consciousness it generates. He used to ventilate when “noticed the loaded atmosphere.” Now I know that when I notice, I’ve been working badly for an hour. It is the difference between driving with velocimeter or eye. The paradoxical thing is that after three weeks, Netatmo has taught me not to need it. My body has internalized the times and signs. I recognize that very slight ocular heaviness, that subtle friction in words flow. But Without the sensor’s objective data, I would never have developed this sensitivity. It’s like learning to refine an instrument: you first need the fingerboard, then your ear learn to recognize dissonance on its own.

After weeks of concern, the Mediterranean is very close to normal. The heat wave threatens to throw everything into the fret

Something has changed sharply in the Mediterranean Sea: its temperature. If a few weeks ago the sea that unites Europe, Africa and Asia burning, now the surface temperature of the sea has plummeted to almost normal values, only slightly above what we could expect during these summer dates A few tenth. The latest data on the surface temperature in the Mediterranean Sea have given us good news in the form of stabilization. According to the data Of the coastal observation and prediction system of the Balearic Islands (Socib), as of August 7, the Mediterranean surface is, on average, at 26.03º Celsius. This implies an anomaly was 0.54º Celsius, that is, the sea is more than half a hot than what would correspond at this time. As a contrast, in the middle of June We reported that this anomaly was 2.26º. East to the west. The sea temperature has decreased on average, but has also changed in its distribution. A few weeks ago the focus of the heat was in the Western Mediterranean, while to the east the temperatures were warm but more moderate. Now it happens just the other way around. According to the Socib datathe average west temperature of the Mediterranean is 25.01º, which implies a thermal anomaly of 0.29º. Meanwhile, the eastern side is at 27.06º, 0.81º more than what would be normal in that area and on these dates. A very diverse sea. The data allow us to analyze the change in different regions and, perhaps the area where this change is most palpable, the Northwest Mediterranean. Here, at the beginning of July the thermal anomaly was around four degrees. Now is the most “normal” area of the sea, with a positive anomaly of only 0.17º. Another of the spotlights a few weeks ago was in the surroundings of the Balearic Islands, especially in the waters of the National Park of the Cabrera Archipelago. In these areas, thermal anomaly on June 12 was 3rd and 3.18º respectively. Now, the environment of the Balearic archipelago is only 0.36º above the average, while the waters of the Cabrera archipelago have an anomaly of 0.35º. What happened? June was an extremely warm month in Spain, but it was also hotter than normal in other areas. The absence of section of section and high insolation made the Mediterranean a boiling pot, but the month of July was different. The arrival of a time less torrid in a month of July in which the storms took the prominence in the Mediterranean basin changed this. “Thanks to the dynamics of atmospheric circulation in recent weeks, with the passage of different troughs, the surface waters of the Mediterranean already draw a panorama with a more normal spatial variability,” explained on social networks The physicist, disseminator and researcher at Aemet JJ German. Without throwing the bells on the flight. The descent of temperatures is great news: a Mediterranean too warm increases the risk of storms and copious rainfall like the ones we see in Danas and in episodes of “cold drop”. The question now is to know if this stabilization will be lasting or if we will see a new thermal rebound in marine waters. August has started with a heat wave in Spain with reach beyond the peninsula. June’s thermal rest has ended and we do not know how this change to the waters of the Mediterranean will affect. The issue is relevant due to the environmental and meteorological problems that this overheating would imply.

He left his tesla Cybertruck plugged in and went on vacation. Two weeks later, the vehicle no longer lit

Imagine the scene. You have a tesla and you are about to go on vacation. The trip will be by plane, so you face an immediate decision:leave the car plugged in During the two weeks you will be out or wait to connect it when returning? If you follow the manufacturer’s recommendations, the answer is clear: it is best to leave it plugged in. That was exactly what Aj Esguerra did, resident in Arizona. The official advice followed to the letter. But when he returned home after his break, he ran into an unpleasant surprise: his Tesla Cybertruck did not respond. This is what they tell in Motorpasion Mexico. What failed? We go in parts. What happened exactly to cybertruck At first glance, everything seemed in order. As the user explains in a group of Tesla ownersthe charger worked, the car had been left with 79 % battery and the Tesla app showed that the load limit It was set at 80 %. But when returning on vacation, Aj Esguerra encountered the last thing one would expect from a connected vehicle: a completely inert cybertruck. “I need help: we were out two weeks and when returning, the Cybertruck does not turn on at all,” he explained. I couldn’t even open the doors. He restarted the charger – the blue light went to flash in red – and began to consider hypotheses: “I live in Arizona and this week we have had record temperatures. Could the battery have overheated and damaged the battery?” AJ contacted the technical service through the app and, as he said, the answer was immediate. “The Tesla service is on its way. They responded quickly through the application and received a call immediately,” he explained. The technicians managed to access the interior of the vehicle, put it in a provisional way and They transferred to a service center For a more complete diagnosis. There came the final explanation. The problem was not the battery, nor the heat, nor an error when programming the load. The failure was in a key component of the Cybertruck electrical system: the Power conversion system (PCS). According to Esguerra, the technicians ruled out that the breakdown was related to having left the car plugged in. In fact, they reiterated that this is still the recommended practice. The good news: Tesla took over the reparation without any cost for the owner. Thus, the vehicle worked normally. What is the power converter and what does it do As Skill-Lync points outthe SCP plays a fundamental role: it is in charge of managing how electrical energy in the vehicle enters and is distributed. When we connect the car to a power outlet, the SCP transforms that alternating current (CA) in direct current (CC) To load the main, high voltage battery. But he doesn’t stay there. Power conversion system He is also responsible for keeping the car’s auxiliary systems – such as lights, internal electronics or sensors – through a second conversion: high voltage to a lower voltage. It is composed of several key elements: CC-CC converters, filters, electronic controllers and a liquid cooling system to avoid overheating. In the cybertruck is located in the auxiliary compartment Known as the “Ancillary Bay”, which requires the removal of some sheets to access it. The official recommendations Tesla makes it clear in the cybertruck user manual: The most important thing to preserve the high voltage battery is leave the vehicle plugged in When not used. This is literally indicated by the manufacturer, which warns that the car, even off, continues to consume energy progressively. And if the load falls to zero, damage that does not cover the warranty can occur. In addition, Tesla recommends not waiting for the load level to be low to plug the car. In fact, he affirms that the system pays better if it is kept loaded regularly, even if it is not used. And in case of a prolonged trip, it advises to calculate that the vehicle loses around 1 % battery per day, although that figure can vary depending on the temperature or vehicle configuration. The background message is clear: nothing happens to leave it plugged for weeks, provided that everything works correctly. Although, as we have seen in this case, sometimes things do not go as expected. So, is it safe to leave the car plugged for weeks? In theory, yes. It is what Tesla recommends and is what Aj Esguerra did. But the case of his cybertruck shows that, in practice, Other factors can come into play They escape user control. For example, a peak of voltage in the electricity grid, a punctual failure in the charger or overheating due to extreme temperatures can trigger a chain of errors difficult to detect if no one is there to intervene. In the absence of supervision, a minor incident may end up becoming a major problem. Esguerra himself acknowledged that, before leaving, forgot to schedule the load for the freshest hours. The Cybertruck was carrying day, in the middle of heat wave in Arizona, for several days in a row. Although Tesla did not attribute the failure to heat or continuous load, that context helps to understand how certain environmental factors can increase risk, especially in extreme climates. So, leaving the car plugged in is recommended. But it is also to ensure that the charger works correctly, that the environment is safe and that the electrical installation is protected against unforeseen events. In that balance between trust and prevention is where you should really reduce the possibilities of meeting any type of inconvenience.

We had been waiting for temperatures down weeks. Once again a price has come: hail

The forecasts indicated that the worst Effects of the Paso de la Vaguada They would make themselves feel between yesterday afternoon and today. Forecasts that seem to be fulfilled, with abundant rainfall and located floods. However, if something has stood out on social networks of the first hours of the arrival of the storms, it has been the large hail that has been collected in some areas. Barcelona, in the center of the storm. The province of Barcelona has been the area where the passage of the trough that since yesterday sweeps the Mediterranean basin has been noticed, leaving in its path important stormy episodes with rain, hail and wind. Yesterday, the State Meteorology Agency (AEMET) He issued a notice Red for extreme risk in the area of central depression of Barcelona. The Aemet data Today show the effects of these stormy episodes in the province: as the 50 mm of rainfall collected yesterday in Prats de Lluçanès, or the 49.6 mm of Caldes de Montbui. At 11:00 today had already been collected 42.2 mm in the town of Vilafranca del Penedès. Hails. However, it has not been the amount of water that has caught the attention of the areas through which the storms have passed, but the hail. Its size, to be more concrete: they have gathered Pedriscos up to five centimeters. Cold trough, hot Mediterranean. The passage of the trough, an anomally deep trough for this time of year, has been the trigger for this situation, but to get here they have had to coaligate different factors. Factors such as Levante’s wind, loaded with moisture, which intermingle with the cold air of the trough, or as the surface temperature of the Mediterranean Sea, still high after several weeks several degrees above what would correspond. This situation has given rise to the appearance of the convective systems responsible for storms and rainfall seen in recent hours. Also of those we will see in the next. Still active warnings. The red notice activated yesterday inside Barcelona is no longer active, but Aemet keeps active A series of notices, including orange notices due to important risk, associated with rains and storms. Active notices affect much of the southeast quadrant of the Peninsula, in addition to the Balearic Islands and areas of the Catalan Pyrenees. The orange notices They concentrate today in the west of Castilla-La Mancha and the interior of the Region of Murcia. Active notices for tomorrow also include orange warnings due to rains and storms that will affect the Region of Murcia. They will be accompanied by yellow notices in a broader region in the southeast of the Peninsula, Catalonia, also the Balearic Islands. Attentive to evolution. The situation will improve only progressively. Some notices Aemet meteorlogics will still be kept active during Saturday in Catalonia, where rainfall is expected to reach 20 mm in an hour. Temperatures however will go up during the day, especially in the opposite area of the Iberian Peninsula: The forecasts The agency advances temperatures above 36º degrees in low areas of the southwest peninsular.

Melilla has been with its collapsed systems for two weeks. Now, Villajoyosa has joined the party

Villajosa City Council (Alicante) has suffered a very similar luck to that of the Melilla: A cyber attack has completely left ko the computer services of the municipality. In this case, the attackers have not yet attributed authorship, and from the City Council they anticipate that the recovery process will last “several days.” What happened. A cyber attack classified as ransomware The municipal computer systems has left out of the City Council itself. At the moment, the damages caused are being evaluated while trying to restore the service as soon as possible. The City Council claims to be working with the Cybersecurity Operations Center (COCS), under the National Cryptographic Center, to accelerate the process of return to normal. Meanwhile, they warn that the systems will be inactive for “several days.” How is this type of attack. Cyber ​​attacks classified as ransomware They have a very concrete purpose: Ask for a ransom. The way of operating is clear and consistent: The computer is infected Your data is kidnapped An economic rescue is requested to release them Who has the computer on, to turn it off urgently. Local media They confirm that the event began last Wednesday night, warning the City Council to its workers to immediately turn off any administration computer. The next morning, the City Council reported that its public service services were “attending manually, with the limitations that in some cases can entail.” Municipal sources point to more than 300 infected computers. A case that sounds to us. The case of Villajoyosa is important because it is the second that Spain suffers in just two weeks. Melilla has been with her collapsed computer services by a cyber attack attributed to a Russian cybercriminal group. At the beginning of this week, the figure requested by the group that assumed the authorship: 1.8 million euros in exchange for almost 4 tb of information. Among her, “all the inhabitants of the city”, tourists and information committed on public office. No solution to sight. Villajoyosa speaks of “several days” to restore the service, but there is no specific date. Melilla already has fourteen days of computer chaos, refusing to pay for the rescue and with the National Intelligence Center (CNI) working to recover the encrypted data. Studies tell us that paying an attack by ransomware increases the chances of attacking you againso the solution is not so simple. (Almost) at the head. Spain It is one of the most attacked countries in the world by cybercriminalshaving suffered a wave of cyber attacks in recent months. The last, this week, investigating a data filtration related to the president of the Government, Pedro Sánchez. Giants like Microsoft bet Por European security programs, offered without cost and in order to share intelligence on threats. Measures and proposals that do not seem enough to a growing phenomenon.
