take advantage of one of the largest sources of renewable energy

by

The energy wave drive It has a great advantage over other more popular renewable energy sources, such as the sun or wind: it never rests. Waves are an almost continuous and enormously energetic resource. And yet, it is the ugly duckling of green energies because its unpredictable and far from constant nature turns energy extraction into a titanic task in terms of efficiency. An American startup, Panthalassa, has been testing for a while In Pacific waters, a prototype that rethinks from the ground up how to relate to the ocean: instead of resisting it, it follows the flow. The invention. He Ocean-2 It is a device that at first glance looks like a giant buoy. In fact, in tests in Puget Sound, Washington, several people reported an unidentified floating object. The spherical part of the end (the node) has almost 10 meters in diameter and is mounted on a tubular hull approximately 60 meters long (which is submerged under the sea). But the analogy with the buoy is accurate in that it is a simple structure that sways with the waves. When it is horizontal it moves and when it is vertical (when it looks like a buoy) it starts working. Why it is important. Because the oceans They cover 71% of the Earth and its energy has an advantage that solar and wind power lack: consistency. The ocean generates energy regardless of whether it is day or night, even if it is calm or the sky is cloudy, which makes this energy source the ideal complement to stabilize networks. The endemic problem of this technology is its low efficiency. If this prototype can be scaled, it could become an alternative and complement to clean and independent energy for coastal areas. Context. In the midst of the race for AI and data centers, the great bottleneck of the United States is the energyso much so that they are dusting off old energy solutions as fossil power plants and resurrecting its nuclear industry. Of course, and although his role in the US, Israel and Iran war is different from Europe and so is its access to oil, the reality is that the price of a barrel being uncontrolled does not benefit them either. In that scenario, it is expanding your investment in renewables. Wave energy has been promising and disappointing for decades. Salt, corrosion, biological growth on structures, and the brutal cost of offshore maintenance have literally and figuratively sunk dozens of projects around the world. The result: almost everything has remained in the pilot phase. Nor has efficiency ever been anything to write home about. And while wave power has stagnated, the price of solar and wind has fallen so rapidly that it has left other clean energies without a competitive advantage. However, wave energy faces another opportunity: Ocean Energy Europe figure The portfolio of planned deployments until 2030 is at 165 MW and the United States has invested $591 million in ocean energy in the last five years. How much energy it produces and uses. In the test he managed to generate up to 50 kW in decent wave conditions, enough to power a small coastal town. However, its priority application is not the domestic electrical network, but something more specific such as clean fuels and computing: producing green hydrogen that is transported to shore in autonomous ships, and powering data centers in the ocean. How they do it. The design of the Ocean-2 has a more philosophical than technical point: it is not so much about resisting the ocean but about accompanying it. As the waves oscillate, water is propelled through an internal pipe to the spherical surface and then descends through turbines to generate power. It has hardly any moving partsbeyond the turbine, integrated into the steel structure The buoy does not have nets or elements that can trap marine fauna, it operates silently and with slow movements: Panthalassa’s environmental manager, Dr. Liam Chen, explained for local TV KOMO that its soft, low-impact design allows you to “live in harmony with the ocean.” Testing in Puget Sound showed no visible alterations to the surrounding marine ecosystem. According to the co-founderGarth Sheldon-Coulson, these machines can be made for around $1,500 per kilowatt. What comes next. As account its co-founder, have been working for about ten years: the first four or five years was only R&D, in 2021 they launched their predecessor the Ocean-1, in 2024 the Ocean-2 was released and the Ocean-3 is already in development and It is making steady progress in its financing. Yes, but. So far, everything is testing and prototypes because the project is in the experimental phase, that is, there is not a single commercial kilowatt generated, nor a connected network, nor long-term durability data. And the sea is not exactly an easy environment: knowing how it will withstand storms and the passage of time, what maintenance will be like or simply something as basic as the transfer of energy from the device to the network is essential. Without forgetting the cost, especially given the collapse in the costs of solar or wind energy, both technologies that are already mature, consolidated and very cheap.

The Coca-Cola recipe seemed untouchable. Until Europe first and Mexico later have decided to touch it

by

For decades, the Coca-Cola recipe has been treated almost like a state secret, guarded in a vault in Atlanta and protected by an aura of mystery. However, in the real world, governments have discovered that they do not need to infiltrate that vault to alter the world’s most famous drink, but can do so through legislative texts. Modifying, for example, the fiscal or regulatory framework can push any company to change its composition, its prices or its supply. The case of Mexico. Without a doubt, it is one of the most solid in the world to understand how large-scale industrial change can be forced. And it is no wonder, because the driving force behind this change was not a direct order to rewrite the formula, but rather the entry into force of a new tax on sugary drinks. in 2014. Here the effect it had was commented on by different studies which showed that, one year after the tax, purchases of sugary drinks fell by 6%, while purchases of water they rose 4%. He had an answer. The fiscal scenario and the drop in sales logically generated strong pressure for the company to change its ingredients, causing great pressure on the mix of the company’s sweeteners. This opened an intense debate about the use of cane sugar versus high fructose corn syrup, and now the national government has put on the table the possibility of forcing Coca-Cola to stop using imported corn syrup and transition towards national cane sugar by selling it much cheaper. In Europe. While Mexico uses fiscal pressure on consumption, the European Union is the perfect example of structural market regulation. And for those who have traveled to North America, you will have realized that the taste of Coca-Cola is different from what is drunk here in Europe. And a very important bureaucratic tangle is also to blame. The culprit was none other than the strong intervention that the sugar market had in the European Union for 50 years through a complex quota system that came to an end on September 30, 2017. Its consequences. Here European regulations historically limited the production of isoglucose, which is the European equivalent of American corn syrup, through strict quotas. This structural restriction forced its use in the soft drink industry to be much more contained than in the United States. Although the European Commission continued to manage certain quantitative limits in the final phase of this legal regime, the regulation acted as a containment dam. Furthermore, several Member States have implemented their own taxes on soft drinks, separating the strategy of “market regulation” from “public health” policies against sugar consumption. In India. To understand how far the fight between a State and the Atlanta giant can go, you have to travel to India in 1977. Here, unlike Mexico or Europe, the debate was not about cane sugar or sweeteners, but about sovereignty and corporate control due to the ‘fault’ of a currency control law that forced multinationals to dilute and reduce their foreign participation. Here Coca-Cola reacted quickly to prevent any government from controlling its operations and therefore sharing its secret formula, and that is why it decided to leave the country in 1977 before submitting and revealing the secrets it had.

vertical tabs and split screen

by

It seemed that AI had arrived in our browsers. In fact, it seemed that the new batch of browsers with AI could change everything, but the truth is that at the moment they have not changed anything. Nor Comet, nor Atlas, nor Day They have managed to conquer us for that aspect. The integration of Gemini in Chrome or Copilot in Edge does not seem to convince us much either. They are striking options, but they remain in the background. The curious thing is that the evolution of browsers has not caught the AI ​​fever, but is gaining momentum with practical, pragmatic and almost everyday options: small details that improve usability and really add up. Vertical eyelashes to power The first of these options is an old acquaintance: the ability to organize our browser via vertical tabs instead of horizontal, it has been gaining ground among more and more users, but the curious thing is that this feature is, indeed, old. Google has just integrated the option to enjoy vertical tabs in Chrome. In fact, Opera I already had a choice of this type almost 20 years ago (if not before) with its “visual tabs”, but ended up abandoning them and in fact today it does not have that option officially although it is possible to add it through extensions. Firefox also adopted that path: it did not have them as standard, but there were those who I was experimenting with that concept. already in 2009 through extensions for this browser. Those who ended up copying and using that option were others: Microsoft Edge did it in 2021Brave in 2023for example, and Vivaldi has them too for a long time. Two of the latest to join this trend are Firefox and Chrome, which has just released this feature. but before, who had made them fashionable again? It was probably Arca browser with many striking ideas that fortunately is now inheriting his successor, Dia, who had erratic beginnings. The success of vertical tabs probably has a lot to do with the way widescreen displays (16:9, 21:9) have ended up conquering our tables. Too much horizontal space and no vertical spacewhich makes vertical tabs make more ergonomic sense than ever. In fact, what is normal in traditional browsers with tabs organized horizontally is that as we open more and more tabs, identifying them (not even with favicons) and selecting them gradually becomes more and more difficult. Vertical organization solves this in a remarkable way, and the fact that Chrome has finally adopted this option is the definitive confirmation that it is valuable to many people… and will probably end up being valuable to many more. Two better than one The second great novelty that is taking hold in the browser market is integrate split screen. Many users—me first—use two browser windows facing each other, one on each side of the screen, but now browsers offer exactly the same thing directly. He maxthon browser was probably one of the first to offer this option: it already had it integrated even before the launch of Windows 10 in 2015. Then we have seen how others have followed in its wake: it did Vivaldihe did Microsoft Edgeand later Opera also added that option. Google has also ended up catching this fever, and added the feature split screen in February 2026. The developers of the most used browser in the world recognized that this type of function “helps people multitask and get more done on the web.” It’s curious because, as we mentioned, this feature was already within our reach thanks to that feature of “Snap” and placing browser windows on both sides of the screen. However, this type of function, although popular, usually requires some familiarity with keyboard shortcuts, although operating systems have been enhancing this ability with more accessible ways to choose the distribution of advantages on the desktop. This function integrated into browsers It is especially useful on laptops or for users of smaller monitors: there, fitting multiple windows in a small space is more inconvenient, and the split screen of browsers can help. But the beauty is not only in dividing the screen: it is that you can open a link directly in the other panel without creating a new tab. The combination of this function with vertical tabs makes the browser gain integers and we can do more in the same space. And the funny thing is that these practical and simple improvements end up being more popular and used than AI functions. The latter may effectively end up “supervitamining” our browsers, but today it’s the little things that win. and it is fantastic that they do it.

an Arabic document from the 17th century has confirmed its existence

by

If we think about characters and civilizations in African history, most of us think of the pharaohs and pyramids of Ancient Egypt and little else. However, there is much more and you don’t have to go far from that enormous continent: just to the south, following the river inland, there were powerful kingdoms with their own kings, their own cities and their own cathedrals (yes, I said cathedral). One of those kingdoms was called Makuria, and its capital was Old Dongola, a great city on the banks of the Nile that for almost a thousand years was a center of power, commerce and culture. Curiously, while Europe was living through the Middle Ages, Dongola was a prosperous Christian city that even stood up to the Arab armies that conquered North Africa. Over time it declined, became Islamized and was almost forgotten, buried under the desert. The history of the region Nubia It is almost a documentary silence. It’s not that nothing happened: it’s that almost nothing was written or what was left had not been excavated. In that darkness, a small fragment of Arabic paper recovered in a garbage dump in ancient Dongola (the north of present-day Sudan) has just marked a before and after. The discovery. The document measures just 10 × 9 centimeters, it was found in a garbage dump inside Building A.1 of the Old Dongola citadel (what has been popularly known there for centuries as the “King’s House”) and it is an administrative order issued in the name of King Qashqash. The king orders a subordinate named Khiḍr to arrange an exchange of sheep with their offspring, cotton cloth, and a headdress between several individuals. The text was written by the scribe Hamad and the research team behind the paper considers that it is probably the response to a previous letter, suggesting that there was an active epistolary network around the court. It is, simply, the king working on his task of administering, managing assets and relationships within his network of power. The first face of the King’s order. M. Rekłajtis/PCMA in Barański et al. 2026 Why is it important. The relevance of the discovery has several levels, but the most direct and immediate is to confirm the historical existence of Qashqash, of which there was previously only evidence through oral tradition, including fragments of the Kitāb al-Ṭabaqāt of Wad Ḍayfallāh. This book compiled in 1700 compiles the biographies of the most important saints and religious teachers of the Sudan, based on stories that had been transmitted orally from generation to generation. Beyond that confirmation, the discovery sheds some light on what the “Dark Ages” of Nubia were like. For centuries the image left by Leo Africanus in the 16th century predominated, describing the king of Nubia as a monarch perpetually at war. This document demonstrates the opposite: the region was politically active and its king was not on the battlefield, but rather involved in the daily management of goods and networks of reciprocal exchange, which was the central mechanism of political power in precolonial Sudan. Context. Old Dongola was the capital for centuries of the Christian kingdom of Makuriaone of the most powerful medieval African kingdoms in the Nile Valley. In the mid-14th century it ceased to be so, and the city progressively contracted until it was reduced to its citadel and its immediate surroundings. What followed is the period that historians call the Sudanese “Dark Ages”: three centuries in which Dongola was caught at a geopolitical crossroads: with pressure from the north by Ottoman Egypt, from the south by the Funj sultanate, and meanwhile its society was Islamized. It was in that delicate context that Qashqash probably reigned between the second half of the 16th century and the first years of the 17th century. one of the first rulers of that dark period that has been able to be verified. How have they done it. The PCMA research team at the University of Warsaw have combined three independent avenues to date and contextualize the document: with numismatics using Ottoman silver coins from the same stratum, radiocarbon of organic matter from the garbage dump, and cross-literary genealogy, combining the Kitāb al-Ṭabaqāt and the account of the traveler Evliya Çelebi, the documented descendants of Qashqash. The convergence of the roads has made it possible to reconstruct the limits of when his reign was. Qashqash is just the tip of the iceberg. The document is also a linguistic testimony of the first order: written in Arabic, it has grammatical irregularities and colloquial spellings that show that although it was not fully established, it was already the language used by the chancellery. In short: evidence of the gradual Arabization of Nubia, which was adopted and adapted. Another interesting point is that archaeological evidence and local oral memory confirm each other. Building A.1 has been called the “King’s House” by the inhabitants of Dongola for centuries and the descendants of Qashqash continue to live nearby. Finding the royal order precisely there is no coincidence: it is archeology validating what the community had remembered for generations. In fact, the collaboration between the research team and those who live there has been close, something they consider essential for a correct interpretation. Shedding light on the dark ages. The Qashqash order is only the first published result of a much larger corpus as the project has recovered approximately fifty Arabic paper documents in Old Dongola, including letters, legal and administrative texts, and written amulets. The first analysis points to communication networks that connected religious, administrative elites and possibly nomadic leaders of the region. A comprehensive and in-depth analysis of the set will shed some light on the political, legal and social history of pre-colonial Nubia.

A study has revealed the key to getting your emails answered: give the "thanks in advance"

by

It has all happened to us at some point: you write an important email, you send it and the only response you get is absolute silence. You review the text, the subject, the recipient, and everything seems correct. According to science, the problem with that email may be in the last two words that close the body of the email, that space that the majority fills in as a formality with a “regards” or “sincerely”, without devoting a second of reflection to it. how it should be worded an email so that don’t fall into oblivion. A study published in the Journal of Personality and Social Psychologyanalyzed hundreds of thousands of email conversations and came to conclusions strong enough to reconsider a habit that almost no one questions, but improves the chances of receiving a response. The experiment that changed everything. In 2017, Boomerang examined over 350,000 email threads extracted from mailing list archives of over twenty different online communities. The goal was to determine whether the way one says goodbye at the end of an email has any real effect on the probability of get responsesomething that until then no one had measured on that scale. The study of these data returned a resounding yes. Closings with expressions of gratitude obtained notably higher response rates than the rest of the usual formalisms, with a difference that can exceed fourteen percentage points compared to the more neutral farewell formulas. The average response rate for all the emails analyzed was 47.5%, a reference figure that allows the real impact of each type of closure to be measured. In Xataka Change Gmail or Outlook for a European alternative: step to follow and what you should take into account The formula that prevails over all others. Among all the closings studied, the farewell with a “thank you in advance” turned out to be the most effective formula, with a response rate of 65.7%. This was followed by a brief “thank you” with 63% and “thank you very much” with 57.9%. At the opposite extreme, closer farewell formulas such as “kind regards” (53.9%), “regards” (53.5%) or “regards” (52.9%) were well below. On the other hand, the “best” formula, the Anglo-Saxon equivalent of “the best”, recorded the worst data of all those analyzed, with 51.2%. The logic behind the most successful terms is simple: writing “thank you in advance” thanks the recipient in advance for a response that has not yet occurred, which creates an implicit expectation of commitment that the recipient tends to fulfill. It’s not a fancy psychological trick, but rather a signal of advance politeness that, according to the data, serves as a consistent and measurable hook. In Xataka The key to being more productive is not doing more things: it is identifying where you are wasting your time The science that explains the phenomenon. The results published by Boomerang match the investigations previous studies conducted by behavioral psychologists Adam M. Grant (Wharton School) and Francesca Gino (Harvard Business School). Their study showed that the expressions of gratitude They directly motivate prosocial behavior, that is, people’s willingness to help. University students who participated in that experiment who received a message with an expression of gratitude closing the email were twice as likely to offer their help as those who received the same message without it. The researchers concluded that the key mechanism is not the recipient’s self-esteem or emotional state, but rather the feeling of feeling socially valued. Apparently, those two formulas that seemed like mere courtesy, activate that spring. {“videoId”:”x86bhjh”,”autoplay”:false,”title”:”17 TRICKS and FUNCTIONS WITH GMAIL GET THE MOST OF YOUR ACCOUNT”, “tag”:””, “duration”:”593″} The numbers that justify the change. When Boomerang directly compared the emails with these thank-you closings to the rest, the difference was even clearer. Messages with some variant of thanks at the end achieved a response rate of 62%, compared to the 46% average offered by emails that did not include it, which represents a relative increase of 36% in the average response rate. It is worth keeping in mind, however, that the analysis itself warns of its limitations and conditions. The sample comes mainly from communities linked to open source software and academic environments, so it may not reflect all professional or social contexts. Even so, the fact that these closures generated a greater tendency to respond confirms that the choice of the appropriate closure is not a minor detail, but a variable. with proven weight.

the astronomical event of the century is approaching

by

Many of us still have the healthy envy of seeing the spectacular images of the total solar eclipse who toured Mexico, the United States and Canada two years ago. It was an event that paralyzed a continent, especially in the so-called “strip of totality”, the areas that were left completely dark. Well, the next great cosmic event has Spain as a global protagonist. And we won’t have to wait long. August 12, 2026. In just four months the first total solar eclipse visible in Spain since 1905 will take place, a unique opportunity in more than a century. Together with Iceland, which will enjoy 58 seconds of totality, we will be the only country in the world that will be able to see all phases of the eclipse. And let’s be honest: in the middle of August, our chances of having clear skies are considerably better than those of Icelanders. Context. A total eclipse occurs when the Moon aligns perfectly between the Sun and Earth, casting a shadow that plunges the lucky ones into twilight darkness in broad daylight. In the event of 2026, this shadow, the strip of totality, will be about 300 kilometers wide and will cross Spain from west to east, from Galicia to the Balearic Islands. The autonomous communities that will remain under the shadow cone of totality are Galicia, Asturias, Cantabria, Castilla y León, the Basque Country, La Rioja, Aragon, Catalonia, the Valencian Community and the Balearic Islands. Madrid will be right on the edge, with a fleeting totality in the north of the region. But the rest of the country will not be left empty-handed and will witness a very deep partial eclipse, with coverage of more than 90% (and up to 74% in the Canary Islands, with Lanzarote as the island with the best seats for the show). Almost two minutes. An essential tool to plan the observation of the eclipse down to the millisecond is the interactive map by Xavier Jubier. This resource is the gold standard for eclipse hunters because it allows you to click on any point on the map to obtain the exact times of each phase, the duration of totality, the altitude of the Sun in the area… You can also consult the map of the National Geographic Institute. The eclipse will begin just before sunset. The totality phase will take place around 8:30 p.m. (peninsular summer time), with the sun already very low on the horizon. This turns observation into a race against time against the setting sun. In cities like Oviedo, totality will last 1 minute and 48 seconds, just a few moments longer than in Burgos, León or the island of Mallorca, which is emerging as one of the most tourist places to see the eclipse (with the disadvantage that the Sun sets earlier than in the northwest of the peninsula). Safety first. As much as it may tempt us to look directly at the Sun, even partially eclipsed, can cause permanent eye damage. During all partial phases (before and after totality), it is necessary to wear glasses certified to view eclipses or indirect methods to observe it. For the rest, it will be enough to find an elevated observation place, with a horizon clear of mountains or buildings to the west so as not to miss what will undoubtedly be the astronomical event of the century.

the “wolf pack” robots with all kinds of autonomous weaponry

by

China has turned robotics into a state issue. In the last five-year plan, the country made clear its total commitment to autonomous robots, agentic AIthe development of your semiconductor industry and 6G as the great ‘cloud’ to give life to Physical AI. Within the technological commitment, we already knew that robot dogs were of great importance. What we didn’t expect is that they already had packs of robodogs ready to go into action. And all this under a brain that makes them work like a swarm. Robowolves. The Asian giant has been performing simulations with these robot dogs armed. The advantage of these units is that the base is the same for all, but they can be customized so that they carry whatever is needed: from weapons to sensors of all kinds. Each one weighs about 70 kilos and can carry another 25 kilos, so the versatility when it comes to having ‘extras’ for attack, reconnaissance, transportation and supplies is maximum. And they can be operated remotely by humans, but the key to the Chinese system presented by the state channel CCTV (as stated SCMP) is that they can also be under the control of a central AI. Herd. We have already mentioned that one of China’s objectives is physical AI, AI being the software that controls – the brain – and the robot the hardware that has contact with the real world -the dog-. Within a show of force, television highlights operations such as “urban cleanup” in which a pack of ‘wolves’ operates through a shared detection network that acts as a collective brain. It is an autonomous mode and decision-making is joint within the group. As in a pack of flesh and blood wolves, each one has different roles. And they have names. ‘Shadow’ is the recognition, giving information about the situation to the rest of the group. ‘Polar’ is the one that offers logistical support and ‘Bloody’, as its name suggests, is the one that can carry weapons such as grenade launchers, missile launchers and automatic rifles. What’s scarier is that the group can automatically maneuver into tactical formations thanks to that swarm control system to surround targets, block them, and ultimately open fire. One of those responsible for researching the Atlas weapons system in China pointed out that these drones “understand” the intentions of others and can execute collaborative actions even in the absence of communication signals with the command. Utility? Operate in situations where satellite signals are not available. An example of one of the ‘Polar’ Limitations. Although it may seem like science fiction – and it is – these units are not perfect. The army itself has revealed on occasion that robodogs lack armor, so they are easily shot down even with light fire. They have recognized that the idea is no longer to achieve perfection, but to advance in the demonstration that they can replace human troops with robots, minimizing casualties in the event of open conflict. There is also something more underlying: as in a pack, the strength is not in the individual, but in operating together as CCTV claims these swarms of robots can do. And another limitation (and thank goodness) is that, although robots are capable of identifying and focusing on targets autonomously, they cannot attack without human confirmation. And a ‘Bloody’ show of strength. The reports shared by CCTV indicate that the algorithms of this system allow collaborative tasks to be carried out between different types of weapons. For example, coordinating attacks between ground and aerial drones, but also guiding laser weapons. One case is an algorithm that allows robots to prioritize targets, such as neutralizing the most threatening ones first, leaving less important targets aside. And Zhang Wei, a researcher at the China Electronics Technology Group corporation, pointed out that the goal is to achieve robots with “full autonomy on a large scale”, a scenario in which many different drones operate collaboratively without human intervention, achieving objectives and making decisions in complex missions autonomously. Total commitment to robotics. As always, you have to take anything that comes from any government with a grain of salt when talking about this type of thing, since (and even more so now) propaganda is super important. However, it is undeniable that China is betting heavily on the development of robotics and that these robowolves are not a render like the ‘space destroyer’ that they showed a few weeks ago. They are already carrying out simulated missions and we have seen them in other scenarios, such as in the daily life of different firefighting units. helping carry out reconnaissance missions and firefighting. And, deep down, I can’t get out of my head how cool these things were when we saw them in the movies and how scary it is when they seem to be one step away from becoming a reality.

Most complete geological map reveals billions of years of impacts and volcanism

by

We have been talking for years not about landing, but about colonize Mars (above all, Elon Musk), but with Artemis II making history and the Orion ship just splashed down After the first manned mission to the Moon in more than 50 years, the old moon has returned to the forefront. Four astronauts have just photograph it up close and leave us with our mouths open. But the Moon is much more than a satellite full of craters: each of those craters tells a story of billions of years. At this moment when our satellite has hit us again, we rescue geological cartography most complete overview ever published. It is the unified geological map of the moonprepared in 2020 by the United States Geological Survey combining data from the lunar reconnaissance orbiter missions (LRO) from NASA and Kaguya from the Japanese Space Agency. The good thing is that although you can see a general sample, you can also download it to have a greater level of detail, since it is at a scale of 1:5,000,000 and derived from six digitized geological maps. Visually, this world map draws attention both for the number of craters and for the shades chosen to color it. The choice of color is not casual or ornamental, but rather each color represents a type of terrain with a specific age and origin. So, at a glance you know whether you’re looking at an ancient lava plain, a recent crater, or the original crust from 4 billion years ago. Without the colors, everything would be a gray mass of craters impossible to distinguish. The moon is full of secrets and this map provides information in abundance to discover them. The unified geographic map of the moon Fragment of the unified geological map of the Moon, scale 1:5M. Via: USGS The moon has five geological eras: Pre-Nectarian, Nectaric, Imbrian, Eratosthenic and Copernican, which range from 4,000 million years ago to today. How to differentiate them on the map? Because they go from purple and orange for the oldest to green and pink for the youngest. All that is seen is the fossilized record of its turbulent youth because it has been “geologically dead” for almost 3,000 million years, but it had a turbulent past as evidenced by its orography. The moon offers a striking visual dichotomy between the highlands (in reddish tones and saturated with craters) and the seas, which are the large dark spots. Of course, they don’t have any water. They are actually basaltic lava plains that filled huge impact basins about 3,000-4,000 million years ago. It is, in short, what we see from Earth. The clear, cratered areas constitute the original crust and are much older. The most characteristic thing about the Moon to the naked eye are the craters, which are something like scars that witness the passage of time: the more softened, diffuse and even buried it appears on the map, the older it is. On the contrary, the sharper, brighter and surrounded by bright rays, the younger. “Lightning bolts” are bursts of dust and rock launched after impact and can extend for many kilometers. There is two especially spectacular craters on the map: Tycho and Copernicuswhose rays cross hundreds of kilometers and are geologically very recent. The part of the Moon that we never see from Earth and that arouses so much curiosity in us (there is a project to install a radio telescope there) is its hidden side: there are almost no blue spots there.

France has begun to retire Windows from its administration. It is the beginning of his divorce from Microsoft, Google and Amazon

by

Digital sovereignty in Europe has gone from being a theoretical concept to something increasingly tangible and desirable with respect to the technology we consume. It is no longer just a trend that is increasingly more individual people are tryingbut has also become an object of desire for administrations and companies. The path to becoming independent from big tech in the United States is not easy and while there are startups like Mistral who gets rich in the processthere is a state that has decided to take a brave step forward: France. In a global environment where data and infrastructure are geopolitical weapons, the French Government, through the Interministerial Directorate for Digital (DINUM), has launched an aggressive roadmap to regain control over their information systems, thus reducing the hegemony of non-EU technological solutions. And it has started with Windows. The decision. In a high-level inter-ministerial seminar, DINUM together with ANSSI, the State Purchasing Directorate and the DGE formalized the most ambitious commitment to digital sovereignty adopted to date by a Western European power. Or what is the same: France wants to exit the American technological ecosystem in a systematic, planned way and with specific deadlines. It is not an experiment, it is state policy. The guideline is clear: map and reduce dependence on technology suppliers from outside the EU. The measure is not a veto but rather a mandatory transition towards a model where public administration must prioritize local or open source solutions, especially in critical services and sensitive data processing. As has declared the Minister of Action and Public Accounts David Amiel: “ We can no longer accept that our data, our infrastructure and our strategic decisions depend on solutions whose rules, prices, evolution and risks we do not control.” Why is it important. From a systems engineering and cybersecurity point of view, the measure is vital for issues such as protecting against Cloud Act of the United States, the law that allows its authorities to access data stored in American companies regardless of where the servers are located. On the other hand, it guarantees that the state maintains its necessary technical capabilities to operate its own infrastructure without depending on proprietary “black boxes” and to heal itself in the event of a change in conditions or other external problems. But this phased migration is much more than an OS change: it involves dismantling the entire associated ecosystem, certificates and applications designed for Windows. It means rebuilding the digital foundations of the state from the roots so that they function with total autonomy and without foreign parts, without citizens noticing the change on the surface. Context. Our daily personal, professional and bureaucratic lives live in an ecosystem governed by hyperscalersthose technology companies like Microsoft, Google or Amazon that dominate storage and cloud computing. This mention is not random: they alone eat more than 60% of the cloud cake, as Statista collects. The increase in cyber threats and the US technological monopoly in the West and its increasingly invasive turn to the privacy of others have done the rest. France has been maturing the doctrine for years “Cloud au Center“. While the ANSSI audited the dependencies on critical infrastructures, its sovereign cloud was being forged as a real alternative. In addition, the European regulatory framework, with the NIS2 directive wave cyber resilience lawhas created the ideal breeding ground. With tools like TchapVisio, FranceTransfert and Socle Numérique (alternatives to WhatsApp, Teams, WeTransfer or Microsoft 365, respectively) France no longer only has a plan, but a real operational base on which to scale. The plan towards sovereignty. It is neither a toast to the sun nor does it have vague and diffuse measurements or distant dates, but concrete, tangible movements and which is either already being implemented or is scheduled to be completed before the end of the year: DINUM abandons Windows and migrates its jobs to Linux. It is the first central State agency to do so. Already underway. Migration of 80,000 agents from the Caisse Nationale d’Assurance Maladie (equivalent to Social Security) to sovereign tools: Tchap, Visio and FranceTransfert. Already underway. Migration of the health data platform to a reliable European solution. Scheduled for the end of 2026. Duties for each ministry: present a dependency reduction plan, which includes databases, antivirus, AI or collaborative tools. For this fall. Yes, but. France has a basic skeleton and a legal framework, as well as public-private coalitions to accelerate the transition through concrete and measurable public commitments. But it won’t be easy. Exiting Windows involves disassembling Active Directory and what is behind it, something that costs a lot of time and money. And migrating 80,000 agents to new tools is not so much a technology problem but rather a problem of implementing new management. Also, go out where. Many European solutions still do not reach the integration, ease of use and capacity (especially in AI) of American big tech, which implies a step backwards in terms of quality. But even if it were possible, moving from a proprietary infrastructure to a sovereign one implies an enormous investment in time, personnel training and data migration. Finally, maintaining and evolving our own infrastructure requires specialized and experienced personnel in a market where talent is scarce and expensive.
