It is not a render or a model: he Japanese Riel Canyon is already physically mounted in the JS Asukaa ship designed to experiment with new technologies. The images, captured from The port of YokosukaThey show the weapon without their exterior housing, apparently ready for the last settings before a possible test at sea. Everything indicates that this test is close. It could even have already been done, although for now there is no official confirmation. The published images by the user @Gov_vessel_fan They show the exposed cannon, without the external roof that normally hides it. At first glance, everything indicates that it is the same prototype as the Agreement, Technology and Logistics Agency of the Japanese Ministry of Defense (ATLA) has tried in controlled conditions. It is not clear if the design has evolved significantly, but its appearance coincides with the one that ATLA has shown publicly on other occasions. Extreme speed, extreme wear One of the great challenges of Riel cannons is the extreme wear. The friction generated when firing high -speed projectiles causes a rapid tube deteriorationaffecting both precision and reach. According to data collected by Naval Newsthe previous trials of the Japanese prototype have achieved speeds of up to 2,000 meters per second, with a useful life of the 120 projectile cannon. Click to see the publication in x Installing a rail cannon is not simply a matter of space. This type of weapons requires a huge amount of energy to function, in addition to cooling systems capable of dissipating the heat generated. All that occupies volume, consumes resources and demands a very careful integration. That is why the JS Asuka, with its wide rear cover and its role as a floating test bench, is ideal for this development phase. Click to see the publication in x Although the current prototype looks bulky and little integrated, the Japanese Ministry of Defense has more ambitious plans. In the DSEI Japan 2025 fairthe authorities They showed a model Much more stylized of the weapon, already thought for operational use. According to National Defense MagazineKazumi Ito, director of the ATLA Equipment Policies Division, confirmed that the development “is progressing”, although he acknowledged that there are still “various challenges” ahead. The intention, yes, is clear: to integrate this technology into new generation destroyers. For years, the United States Navy led the development of Riel cannons, but in 2022 he decided to officially abandon the project after multiple delays and technical complications. He never did such advanced tests. Japan, on the other hand, has chosen to continue exploring this route, And he is doing it in collaboration with the North American country.

Goal has been spying on everything we did when navigating our Android mobiles. They have caught it in fraganti

June 4, 2025 by usatoday24

Billions of users have been exposed to a new system of mass tracking and espionage that both goal and Yandex have used. Both companies have used a technique that took advantage of native applications such as Facebook or Instagram and then monitor everything we did with our mobile browsers. It is a drop more than one glass already Absolutely full: The attack on Our privacy. What happened. A group of researchers from the IMDEA Networks agency and the Universiteit Radboud of the Netherlands, led by teachers Gunes Care and Nerseo Vallina-Rodríguez, published yesterday An extensive technical article. In it they revealed the technique that they have baptized as ‘local Mess’ (‘Lo Local’) and what a goal has been using since September 2024 and Yandex much earlier, since 2017. What does ‘Local Mess’. We will focus on goal and its applications, although the method is analogous in Yandex. Android users who use applications such as Facebook or Instagram could be exposed, because those applications “listened to” what happened in the Browsers installed In our mobile phones using local ports (hence the ‘Local Mess’) with the aim of tracking and monitoring everything we did in our browsers. The user did not know anything. The method allowed these applications to achieve Receive metadata, cookies and commands that were executed in the browsers. The Meta JavaScript code, called Meta Pixel, was loaded silently and without warning as a kind of complement to mobile browsers, and connected to apps such as Facebook or Instagram. Discouraging users. As these researchers explain, the method allowed access device identifiers that are used for advertising systems, called Android Advertising ID (AAID), and that made it possible to associate everything the user did to a real identity (a Facebook or Instagram profile). The result: what we did in the browser was no longer anonymous or private. Neither unknown, nor delete cookies nor anything. This “web-top” method eludes systems that theoretically should protect this type of tracking. Thus, neither Delete cookiesnor navigate in Incognito mode It worked when trying to escape that tracking. In fact, the method “opens the door for potentially malicious applications to fit the user’s web activity,” they explain in the document. Exploiting our “localhost”. Meta and Yandex scripts are slightly different, but both make improper use of unauthorized access to sockets from our localhostthe reserved name that our device has on the local network and that is always the IP 127.0.0.1 (in IPV4) address. The Android operating system allows any application installed with Internet permission to open a listening socket in the Loopback interface (127.0.0.1). The browsers that are executed on the same device also access this interface without the consent of the user or the mediation of the platform. This allows a JavaScript code embedded on web pages to communicate with native Android applications and share identifiers and navigation activity. Millions of affected websites. For the goal to work in the method, he took advantage of his cookie _FBPvery widespread on websites that make use of this platform. According to Builtwith, a website that allows monitoring the adoption of different technologies, that goal Pixel is embedded in more than 5.8 million websites among which are Xataka. There is a search engine in the final part of the study that allows you to know if a website was exposed and the activity in it could be registered by these scripts. Scheme of the attack of the attack. Source: Local Mess. Theoretically, only on Android. The researchers reveal that they only managed to obtain empirical evidence of this technique in Android mobiles. They have not observed such a problem In iOS browsers Or in the applications they evaluated, although they point out that technically achieving something like this on the iPhones is feasible. Browsers protect themselves. Those responsible for the discovery have followed a communication policy responsible for vulnerabilities and have contacted several browse developers. Chrome already has prepared the patchFirefox’s is in development – but it seems not exposed to the problem in the case of goal – Duckdugo has already solved it and Brave was not affected When using a lock list and when required explicit permission of user for communications with the premises. There is no information on the progress of the patch in Microsoft Edge, which was affected. And goal has deactivated that option without further ado. Although browsers have taken measures, they are late. Not because there is no solution or the code has been modified, but because goal has decided to stop using it without saying anything. Yesterday the Meta Pixel script stopped sending packages or making requests to localhost. The code responsible for sending that cookie _fbp, indicate in an update in this report, has been almost completely deleted. Why did this goal? There is a hypothesis about the implementation of this technique by the goal: it could be due to how Google was intended to get rid of third -party cookies in Chrome At some point in 2024. That would have affected companies as a goal, which perhaps would have reacted trying to collect that information with this technique to have a plan B if cookies disappeared. What says goal. In Xataka we have contacted those responsible for the goal in Spain, and we will update this information if we receive an answer. In The Register they indicate that after contacting the company, Meta has indicated that: “We are in conversations with Google to solve a possible communication error in relation to the application of their policies. When we are aware of the concerns, we have decided to pause the function while we work with Google to solve the problem.” What Yandex says. The Russian company has made comments about the problem. Speaking to Android Authority, they explain the following: “Yandex strictly meets the data protection standards and does not discourage user data. The function in question does not collect any sensitive information and its only objective is to improve the customization of our applications. After examining the problems … Read more

Navigating from Madrid to Lisbon, the pharaonic real dream that gave rise to the failed Channel del Manzanares

March 22, 2025 by usatoday24

The Manzanares river in Madrid has become one of the protagonists of recent days. March is being an extremely rainy month, so much that it has caused Solar energy ceases to grow in Spainbut has also caused the River overflow throughout the country. One of those rivers is Manzanares, which is usually a thread of water and Now it’s a torrent. But the river has not only become news for the increase in flow, but because during the works of Metro line 11 they have found a section of the real historical channel of Manzanares, an ambitious project that It was centuries on the table and that had a target target: join Madrid, Lisbon and Seville by boat. Felipe II’s dream Felipe II It is not just one of the most remembered kings in Spain: it may also be from Europe. Under his reign, The Spanish Empire reached its peak And it was a monarch interested in finance projects of several sciences. He also liked the sea, starting maritime engineering projects, stimulating the creation of large warships and the most ambitious of all: the idea of making The main rivers of the peninsula were navigable. Another detail for which Felipe II is remembered is for the move of the capital of the country: he decided that Madrid would be the ideal location, so he transferred the court in full. But of course, Madrid did not have direct access to the sea and this was something important, especially for trade and those expansionist ambitionsso the project To open Madrid to the sea, he made eyes to the king. And the task fell into the hands of the Italian engineer Juan Bautista Antonelli. Nothing, something simple: Tajo, Duero, Guadalquivir and Ebro, among other rivers, would become navigable, with channels among them that would allow Madrid to have a way out of the sea and a river connection with some of the main cities of the country. For commerce, this was an extremely juicy idea between cities and between Madrid and European, Chinese, African and Indian cities. Fourth Lock of the Real Canal del Manzanares Felipe supported the project And he released funds to be carried out, but it was not going to be simple: a slope of more than 600 meters had to be saved and the necessary adjustments first to open Madrid and, later, that the 600 kilometers that separates the capital from the Atlantic coast were completely navigable. HE I would continue The route of the river and They would create 10 locks between the Toledo bridge and the Vaciamadrid jetty, many for a distance of just 20 kilometers. The capital would join with Aranjuez and, through the Tagus, it would have an exit to the Atlantic by Lisbon. A road was also projected to Seville. He did not set. Although the works are They started Among the Madrid and Alcantara Madrid nuclei, the money was not unlimited and the cocktail of technical difficulties, issues with private properties and, above all, The financing of the invincible Navycaused the money to be redistributed and the interior navigation project was saved in the drawer. He also influenced that, in 1588 Antonelli died and, in 1598, Felipe would. Madrid with double exit to the sea Later it was tried to recover, but the decisive moment came under the reign of Carlos III. Businessman Pedro Martinengo took the witness and presented In 1769 the project to recover the ambitious plan of Felipe II. The construction began in 1770 when Carlos III approved the proposal and the initial funds were in charge of Martinengo himself and private investors he had gathered. Under the direction of the businessman, the project advanced completing eight of the ten planned locks, but the costs were being tremendous and ran out of funds to continue. Martinengo had ruined, but Carlos III liked the projectso bought and thus officially became the Real Canal del Manzanares. The tenth lock Nor do we think that the monarch invested too much: he maintained what there was. Nor is it that he caught the economy at its most buoyant time and the river itself was not the most appropriate for navigation, since it needed water transvases to be able to operate correctly. Some companies were established, such as furnaces, but the channel was being underutilized. With Carlos IV, the thing didn’t improve either. Again, invested just as to maintain it, But in 1799 the disaster arrived: strong rains took part of the Gasco dam, a new construction on the Guadarraman that was the one that was taking the money. Another lock This set of misfortunes, and seeing that the Manzanares channel had been stagnant decades without contributing what was promised, caused the abandonment of the project until the arrival of a Fernando VII who tried to recover it, building the ninth and tenth lock and carrying the work until the vicinity of Vaciamadrid. But the work was not finished. Progress arrived Upon stopping, the channel was degrading, but the last nail in the coffin was the passage of time. In the time of Felipe II, the project could make sense. With Carlos III too, but already entered the 19th, things had changed a lot. The development of roads and, above all, the arrival of the railroad made the priorities change. Why keep investing a fortune to open Madrid to the sea when there were faster than the ship to transport goods? Apart from what The Manzanares channel looked like a money background wellin 1851 the Aranjuez train was inaugurated and, although with Isabel II some boats had sailed through the channel, in the second half of the 19th century it was decided to cut the tap of the funds. When not staying and being water is for a long time, health problems began to appear. The channel became a danger and, although maintenance work began again, around 1860 it was decided Cancel Definitely the pharaonic project. The irony: the railway bridge over the Manzanares … Read more
