The definitive map of Ulysses’ journey in ‘The Odyssey:’ Christopher Nolan’s film, explained interactively

Today is the day. Today ‘The Odyssey’ premieres. Three years have passed since Nolan’s last breakthrough in traditional cinema, ‘Oppenheimer’. And this Homeric feat aspires to nothing less. The new pretty girl from Universal Pictures that uses the most advanced IMAX technology is already placed in the highest position in the career of a director, Christopher Nolan, author of gems such as ‘The Dark Knight’, ‘Memento’ or ‘Interstellar’, who has not surrendered to anything other than his personal vision. Because yes, to the complaints of resorting to white marble instead of classical polychrome, to that mania of making actors very sexy with studded leather and stylized helmets, comes the question of historical reconstruction. Can? Maybe. We have made our attempt and we have something more historically accurate: a map. But not just any one: a dynamic tour that includes the entire journey point by point and draws connections between facts and fictions. Let’s travel together through the great epic of the Mediterranean. We leave the editorial debate to authorities such as Vinzenz Brinkmann, Barry Strauss or Robin Lane Fox. When Homer wrote the Odyssey, probably between the years 750 and 700 BC. c.the map of the Mediterranean ended long before where Europe ends today. Beyond were the monsters, capricious gods, impossible islands and an ocean that no one dared to describe. Two thousand seven hundred years later, the big question remains the same: where did Odysseus really travel? And, why not ask, did it ever reach what is now Spain? The short answer is no. The long one is much more fascinating. We have the historiography of Strabo, Herodotus, Avienus, Pindar, Apollonius of Rhodes, Diodorus Siculus and Pliny the Elder. Their references explain why Gibraltar, Tartessos and southern Hispania ended up being incorporated into the Homeric imagination without Homer having ever mentioned them. That part is often overlooked but we want to review it thoroughly. Let’s travel to the key moment. It all started with a war that (maybe) did happen The Odyssey It starts when the Trojan War has already ended. Ulysses—or Odysseus, as you wish—tries to return to Ithaca after ten years of combat. This is the more or less approximate historical chronology so that we can situate ourselves: c. 1250-1180 BC. C.: possible Trojan War. c. 1170 BC C.: journey of Odysseus. c. 750-700 BC C.: Homer writes the Odyssey. 7th-6th centuries BC. C.: the Greeks arrive in Iberia. Today’s archaeologists rely on a real conflict. Excavations at Hisarlik in Türkiye have shown that Troy existed and that one of its cities It was destroyed around 1200-1180 BC. c., right at the end of the Bronze Age. It is difficult to know if Achilles, Hector or Ulysses existed, but the historical scenario is compatible with a great war between Aegean kingdoms. If that war inspired the poem, Ulysses’ journey would have occurred around 1170 BC. C. However, the story we know was written about four centuries later, when many of those memories had already been mixed with legends. Ten years wandering around the Mediterranean As any reader remembers, Ulysses’ journey begins in the ruins of Troy: “Talk to me, Muse, about that man of multiform genius who, after destroying the sacred city of Troy,” declaims the first verse of Canto I. Violently destroyed around 1180 BC. C., Troy VIIa It is the main candidate for having inspired the conflict, according to the German Heinrich Schliemann, who decided to search for the real place in 1871. From there he sails to Ismaro, the city of the cicones, on the present-day coast of Thrace. Then the lotus eaters arrive, whose fruit makes one forget the desire to return home; the island of the cyclops Polyphemus; the kingdom of Aeolus, guardian of the winds; the laestrygonians, anthropophagous giants; the island of Circe; the descent into Hades; the passage alongside the sirens; the strait guarded by Scylla and Charybdis; the island of the Sun, where his men sacrifice the sacred cattle of Helios; the island of Calypso, where he remains captive for seven years; the land of the Phaeacians and, finally, Ithaca, the small island in the Ionian Sea that some authors insist on not pairing with the Ithaca of the work. Perhaps it was Leucade, Kefalonia, Duliquio, or Corfu? It doesn’t matter to us. The reality is that Odysseus’ route is estimated between 3,800 (from 40º East, that is, Troy, to 6º West, Hades of Gibraltar) and 4,650 kilometers, in an area of ​​more than five million km²perfectly navigable in a much wider sea. Of course, there are proposals for locations that even talk about Ireland, the Black Sea or the Azores. Or that the nymph Calypso kept Ulysses locked up on Parsley Island for seven years. What is clear, because the book says so, is that the journey takes ten years, twenty if we count from the departure to the return: when he returns, his son Telemachus is already an adult and barely retains memories of his father. I repeat it in the list, which is easier this way: Troy Ismaro (cicones) Country of the lotus eaters Cyclops Aeolus Laestrygonians Circe Hades Mermaids Scylla and Charybdis Trinacia Ogygia Esqueria Ithaca Many of these places can be related to real scenarios. The mermaids are usually located off the coast of Campania. Scylla and Charybdis are reminiscent of the Strait of Messina, between Sicily and Calabria. The island of Circe has been identified with Mount Circeo, south of Rome. Other episodes remain open because Homer never offers precise coordinates and whoever reads a specific point on his narrative map is because, too often, it is contaminated by some proximity bias. Your Mediterranean, more than an atlas, is a sandbox. Gibraltar was the true end of the world Even Spain is part of that playground. When Homer wrote the Odysseythe Greeks knew the western end of the Mediterranean, but little else. But between the 7th and 6th centuries BC. C. they began to sail further and founded colonies such as Emporion … Read more

In Asia they haven’t put ice in the water during meals for centuries. Digestive physiology just explained why they were right

The other day a friend told me about a peculiarity she observed during a recent trip to China: the glass of ice water on the table is almost a rarity. Instead you’ll find a pot of green tea, a bowl of broth, or just nothing cold. For centuries, in much of Asia, drinking cold liquid during a meal has been an eccentricity more typical of the West than there. What for a long time seemed like a quaint custom, or directly a matter of infrastructure—ice was not always available everywhere—turns out to have a pretty solid physiological explanation. The temperature of the water we drink while we eat is not a minor detail. It affects the movements of the stomach, the rate at which it empties, and how the muscles of the digestive system behave. And science, although with important nuances, is beginning to agree with what millions of people in Asia have been practicing for millennia. Before getting into the physiology, we must understand how this debate has reached the West. It has not been through a medical congress or a scientific journal. It has arrived, like so many other things, through TikTok. The phenomenon is known as chinamaxxing either Becoming Chinese: a viral trend in which thousands of Western people adopt lifestyle habits from Chinese culture, including drinking hot water. According to documents The New York Timeshot water has become “the new superstar of online well-being”, with influencers documenting how this habit deflates them, gives them energy and improves their digestion. But what the Internet presents as a revolutionary discovery is nothing new. This practice has been rooted for thousands of years. in Indian Ayurveda—where the morning ritual of drinking hot water is known as usha paana— and in Traditional Chinese Medicine, where cold is believed to “turn off the agni“, the digestive fire, and weakens the vital energy or Qiforcing the body to expend extra energy to warm the stomach. Hot water, on the other hand, balances the Yin and the Yang and keeps the body calm. Just because something is part of an ancient tradition does not automatically make it scientific truth, of course. But it doesn’t disqualify him either. The question is what exactly science says when it begins to analyze what happens in the stomach according to the temperature of what we drink. What really happens in the stomach? To understand the debate, we must separate two things that are often confused: the effect of drinking water during a meal and the effect of the temperature of that water. They are different questions with different answers. On the one hand, regarding water itself, there is a widespread belief that drinking water during meals dilutes gastric juices and digestive enzymes, slowing down digestion. Medical portals such as HealthLine They explain that there is no solid scientific evidence that water dilutes gastric juices or significantly hinders digestion. The stomach has a dynamic regulatory system that detects changes in pH and automatically secretes more hydrochloric acid to compensate. Drinking a glass of water during a meal hardly alters that balance. Marina Domene, head of nutrition at SHA Spain nuances in Vogue Where is the real limit: the problem is not drinking water, but excesses. “What is not recommended is drinking excessive amounts, more than two or three large glasses, as it could distend the stomach too much and temporarily dilute the enzymes,” he explains. It also points out that there are specific contexts where it is advisable to be more careful: in people who suffer from hypochlorhydria – low production of stomach acid – it is not recommended to consume liquids during meals. On the other hand, regarding temperature the panorama changes and this is where physiology begins to agree with Asia. The temperature of the liquids directly affects gastric motility, that is, the muscle movements of the stomach that drive digestion. Domene explains it clearly: “Cold drinks can slightly slow down gastric emptying and constrict the blood vessels of the stomach, which in sensitive people can be heavy. Hot liquids, such as broths or infusions, have a relaxing effect on the smooth muscles of the stomach.” This is not just a clinical opinion. There are studies that support this, such as research on the effect of temperature on gastric emptying have observed that very cold drinks, around 2-5 °C, can temporarily slow down the initial phase of gastric emptying compared to liquids at body temperature. Drinks at 4°C also disrupt antral and pyloric contractions, briefly retaining stomach contents. An experiment with 11 young men who consumed 500 ml of water at different temperatures found that water at 2 °C reduced the frequency of gastric contractions compared to water at 60 °C, and that lower muscle activity was related to lower subsequent caloric intake. The sample sizes of these studies are modest—it should be said—but their results consistently point in the same direction. A study published in Gastroenterology Nursingfocused on patients who had recently undergone colon surgery, observed that the consumption of hot water had a positive impact on subsequent bowel movements. It is not a study designed for healthy people, but it adds evidence about the role of temperature in intestinal motility. Gastroenterologist Dr. Lisa Ganjhu, consulted by The New York Timesdescribes it more graphically: during the night, the digestive system slows down. Hot water generates waves of contraction and relaxation in the muscles of the esophagus, stomach and intestines. “It’s basically telling everyone, ‘Okay, get up. We’ve got to get going,’” he explains. Why did they take that path and not another? The physiological explanation that science offers today connects quite well with what traditional Chinese medicine and Ayurveda have been saying for centuries, although in completely different languages. In China, Japan and much of Southeast Asia, It is common to accompany meals with hot tea or soup. It is not a fad or a recent trend: it is part of the structure of food. The broth does not close the menu, it accompanies … Read more

The CEO of a technology company has explained to his employees why he will not raise their salary: they will spend it on AI

That AI doesn’t take your job It does not free you from suffering the consequences of its implementation. And if not, tell the Teradata employees who have seen how their salaries were frozen this year, not to balance somewhat tight accounts, but because they have decided that every available dollar should go to AI. what has happened. They tell it in Business Insider. In January of this year, Teradata CEO Steve McMillan sent an internal message to the company’s 5,100 employees telling them that they should not expect a salary increase in 2026. Teradata’s goal for this year was to “win in the market with AI,” for which they need to increase investment in AI talent and tools. In Xataka An Atlassian engineer was fired. He then published a video on YouTube explaining how the company works When AI takes your paycheck. According to two employees of the company with more than ten years of service, they normally received an annual raise of between 2 and 4%, but this year they have been left without it, although they were able to receive a performance bonus and shares. This measure affects countries where regulations do not require wage adjustments linked to the market. Teradata is not the only company that has preferred to invest in AI over people. The consultant TTEC also decided to pause its contribution to the retirement plan 401(k) because they are going to focus on AI certifications, tools and automation. A choice, not an inevitability. Speaking to Business Insider, the labor expert Jennifer MossHe affirms that cutting employees’ pockets is not the only way out. It is true that both Teradata and TTEC have recorded revenue declines (5 and 3.2% respectively), but there are options such as resorting to external financing to pay for the investment in AI, cutting non-essential expenses or adjusting senior management compensation. It also mentions alternatives such as staggering investments in AI over time, resorting to strategic acquisitions or accepting lower margins for a limited period, instead of loading the entire cost of the transformation on salaries. AI and augmentations. We recently talked about the logic of salary increases has been broken with the arrival of AI. Previously, raises were granted based on parameters such as experience, seniority and job category. However, in the technology sector this scale has changed and in 2026 many companies have frozen their salaries. Although AI is not directly responsible as in the case of Teradata, it has contributed to creating an elite of highly paid profiles and has amplified the gap: now the company you work for and how central AI is to its business matters more than your simple progression from junior to senior. {“videoId”:”x806n3d”,”autoplay”:false,”title”:”TECHNOLOGY and THE JOBS OF THE FUTURE – Insert Coin with Manuel Hidalgo”, “tag”:”employment”, “duration”:”1806″} Firing is expensive. Normally when we talk about the impact of AI on the labor market, we talk about layoffs. So far this year, it is estimated that 92,000 tech employees have lost their jobs with the excuse of compensating investments in AI. However, the reality is that the layoffs are costing them a fortune for compensation and exit packages. Oracle, for example, has reserved 2.1 billion to cover compensation after lay off 30,000 employees. To avoid legal disputes, giants like Microsoft or Google are betting on incentivized “voluntary layoffs”, assuming the enormous risk that their best AI talents will take the money and go to the competition.

Hubble made us believe that this exoplanet was impossible. James Webb just explained why we were wrong

In 2014, the exoplanet WASP-94A b was discovered, a hot Jupiter with an anomalous amount of oxygen and carbon in its atmosphere. The first observations pointed to hundreds of times more of these two gases than in the atmosphere of the Solar System’s Jupiter. This did not fit with standard models of planetary formation. It could be that there is some error in the models. However, according to what has just been verified with the James Webb Space Telescope, the problem was rather that the right telescope was not being used. Closer observation has shown that oxygen and carbon levels are actually much lower, consistent with known physics. Also, as a tip, something very curious has been discovered: that the planet has rocky clouds during the day that disappear when sunset arrives. A very useful transit. The authors of a study recently published in Science They took advantage of a transit of the planet in front of its star to study its atmosphere with the James Webb telescope. Previously, observations were made with the Hubble telescope. With it, the light spectra coming from the atmosphere could be analyzed and, with them, their composition could be established. However, since it was not a telescope capable of distinguish clouds from the rest of the atmospherethe calculations were an average of the gases of everything together. Said by one of the authors of the studywith Hubble the result was something like looking through a foggy window. Now, after giving the window glass a good look, they have been able to see exactly the composition of both the atmosphere and the clouds. Tidal lock. This exoplanet is tidally locked. This means which takes the same time to orbit its star as it does around itself. The result is that it always has the same face facing the star, so on half the planet it is always day and on the other half it is always night. It’s something like what happens to us on Earth with the Moon, which always has a hidden side for us. Despite having perpetual days and nights on each face, on this type of planets you can distinguish between sunrise and sunset, depending on the flow of gases in the atmosphere. The limit at which cold gases from the night side pass to the day side is considered the dawn of the planet, while the limb in which the opposite occurs is sunset. Different compositions. When observing the planet in full transit, the day side could not be seen, since it was looking towards the star. On the other hand, the James Webb has been able to capture the emissions from the two limits with the night side, considered sunrise and sunset. In this way, he has been able to verify two important pieces of information. On the one hand, what we mentioned: the levels of carbon and oxygen in the atmosphere are only five times higher than those of Jupiter. It is something that corresponds to other hot Jupiters and does not defy known physics. On the other hand, it has been seen that on the sunrise side there are clouds composed of silicates. That is, rocky clouds. However, these dissipate until they disappear on the evening side. Thanks to this duality, it has been possible to explore the pure atmosphere, with hardly any clouds, in the area of ​​the planet close to sunset. Unknown causes. The authors of the study do not know what causes this strange behavior of the clouds. However, they have two hypotheses. The first would be something similar to the process that gives rise to fog on Earth. The clouds would form in the darkness on the night side, then enter the intense heat of more than 1,000 degrees on the day side. The substances that make up the clouds would boil and the clouds would vaporize throughout the day, disappearing completely at night. Then, on the night side, the process begins again. The other hypothesis, on the other hand, suggests that there may be intense winds on the planet that are dragging the clouds into the interior of the planet and taking them out of sight by sunset. And now what? These scientists are already studying other hot Jupiters. At the moment, they have already detected two others with the same distinctive cloud cycle: WASP-39 by WASP-17 b. There is nothing like a good sample to properly study any scientific phenomenon. The more planets that are detected with the same circumstances, the better the reasons can be clarified.

The brutal crisis of ViñaRock in one year is explained in an empty venue

The ViñaRock audience debacle is no longer a secret: the clear highlight of the edition, the Sex Pistols (or the group that today bears that name, without the band’s classic vocalist, Johnny Rotten, at the helm), played in front of around 100,000 people. A year earlier, the same event had brought together 240,000 attendees. ViñaRock is the main victim of the crisis unleashed by the financing of several Spanish festivals by Israeli investment funds. The vindication, part of its DNA. ViñaRock was born in Villarrobledo in 1996 with a very specific profile: combative rock, affordable prices and alternative spirit. This differentiated it from other macro events and also favored the approach of the public and bands with very explicit political positions leaning to the left. It did not take long for it to grow until it became one of the main festivals in Spain under the motto ‘Neither God, nor country, nor king’, becoming the largest of its kind. In 2025 it brought together 240,000 people and generated 22 million euros economic impact in the region. The numbers of 2026. The public number of attendees was 100,000 in three days, less than half that in 2025. The organization presented it as a relative successalthough the economic impact falls: of the 22 million generated in 2025, around 11 million will remain. To compensate for the lower external influx, the festival allowed access by the residents of Villarrobledo through its registration program, a formula that for years reserve tickets at starting price for residents of the municipality before the general sale. In the 2026 edition, this preferential access had more weight than ever, and the result was something that in networks It has been closer to the classic image of a patron saint festival, more than a classic rock festival. How it started. In May 2025. El Salto published an investigationrevealing that Kohlberg Kravis Roberts (KKR), an American venture capital fund, had acquired in 2024 the promoter Superstruct Entertainment for around 1,400 million euros. Superstruct manages nearly 80 festivals around the world and, in Spain, it has more than twenty events under its umbrella, such as Sónar, Arenal Sound, FIB, Resurrection Fest, O Son do Camiño, Monegros Desert Festival or ViñaRock. The crisis came when it became known that KKR maintains positions in Israeli cybersecurity companiesis the main investor of the German media group Axel Springer (which has real estate activity in occupied Palestinian territoriessomething contrary to international law) and its president for the Middle East moved in May 2025 to the Civil-Military Coordination Center run by US army officials in Israel. For many regular bands on the circuit, it was a very difficult issue to ignore. Cancellations begin. The rap-metal group Sons of Aguirre & Scila was among the first to formalize the boycott: in a statement announced that he would not participate in any festival in the KKR orbit again until the owners changed. They were soon joined by Fermín Muguruza, Los de Marras, Sinkope, No Konforme, Residente, Judeline and Samantha Hudson, among others. The ViñaRock tried to do damage controlreaffirming their artistic independence, condemning the situation in Palestine and announcing legal action against what they considered a smear campaign. New poster. In February 2026 It was made public that the festival had been acquired by Orange Alive, and an attempt was made to rebuild the 2026 edition practically from scratch. It didn’t help much, because that same month it was made public that They were still linked to Superconstruct. The poster featured groups such as the Sex Pistols with Frank Carter, Turbonegro, Skindred, Celtas Cortos, Medina Azahara, Kiko Veneno and Barón Rojo. The tickets started at 39.99 euros, notably lower than previous editions, and the videos on social networks left images of the events for posterity. half empty stages. He’s not the only one. The ViñaRock crisis is far from being the only one: the concentration of festivals in the hands of large financial groups is a consolidated trend in the live entertainment industry. Other festivals in the Superstruct orbit may face similar reactions from the public and groups, although Resurrection Fest, similar in nature to ViñaRock, broke attendance record shortly after the controversy broke out. Quite possibly, ViñaRock has been affected by both the boycott and the little time it had to restructure its lineup after the defections.

The best tricks to improve your prompts in Claude, two types of structure explained by the Claude team itself

Let’s tell you two structures to create better prompts in Claude, explained by the Anthropic team, creators of this artificial intelligence. They are very precise structures for this specific AI, although they will also work well in other alternatives such as ChatGPT , Gemini either Copilot inter alia. This is something more advanced than when we taught you how to improve Claude’s answers in a simple way. This is a lesson in good prompting practices using engineering engineering. promptsthe practice with which to improve the commands you give to applications LLM. Come on, these are tricks to learn how to communicate with an AI more effectively and shape its responses so that they are better, more reliable, and more tailored to the task you want it to perform. We are going to offer you two prompt structures. The first is a simple five step structure. It is perfect for relatively simple or slightly advanced tasks, and we are going to explain it to you in depth. Then there is a structure for much more sophisticated tasks that has ten steps, and in this case we are going to summarize it for you. Five-step structure of a good prompt The best way to communicate with artificial intelligence and with Claude in particular is to know the best structure for a good prompt. These structures are set up to make sure you give you all the information necessary for the AI ​​to correctly understand what you are asking it to do. This is the best structure for a prompt according to Anthropic: One or two sentences to establish the role and description of the task you want me to do. Add dynamic content to contextualize Detailed task instructions Examples of what you want it to do (optional) Repeat critical instructions (especially when you write a very long prompt. 1. Describe the role and task to be performed As you can see, first of all you need to spend some time establishing the role of the AI, saying what role it should play. For example, telling you that you are a high school teacher, or an AI specialized in reviewing accident reporting forms. Along with the role of AI, it is also recommended describe the task to be performed. Come on, this is where you have to tell him what you want him to do by playing the role that you have indicated. These two elements should be the beginning of a good prompt. 2. Add dynamic content to contextualize After describing the task, it is helpful to provide content to better contextualize your task or the content you want me to work on. For example, if you want it to analyze a text, a photograph, or even a web link, you should add it after the description. This content can also be another element that you have obtained from an application, or even from an AI, whether it is a screenshot or something else. The main thing is that add what the AI ​​needs to do what you asked it to do. You can attach several files, but then you will have to describe well what you want it to do with each one. 3. Detailed task instructions At the beginning of the prompt you have told it in summary what you want it to do, and then you have attached the content on which you want it to work. Now, after this introduction you will have to detail task instructions What do you want me to do? This fragment of text becomes the heart of the task you are programming. You will have to tell it what you want it to do precisely, just as if you were telling it to a person so that they understand it correctly without having to ask you anything else. If you have added several images or different types of content for context, you will also have to explain what you want it to do with each of the elements. 4. You can give him examples of what you want him to do When you do not give the AI ​​any example of the result you want it to offer you, it is what is called a Zero-shot or “0 examples”. With this, you will blindly trust that the artificial intelligence model knows how to do the task. However, when you want to obtain very specific results or with a specific formatthen you should explain this with examples. You can use a single example or multiple examples. By doing this, the model will see the examples of the task already classified or solved, and will use that information to generate the new answers. keeping the same response format that you have indicated. The more examples you give, the more precise the answer format will be. This is optional, but in tasks that require a specific type of response it can be very useful. 5. Repeat critical instructions. You’ve started by describing the task, and then you’ve given him a thorough description of each step he must take. But if you’re asking it to do a very complex task with a particularly long prompt, it’s a good idea to at the end repeat the most critical instructions of the task you have asked him to do. This is the equivalent of underlining the most important and vital points of the instructions, something that you think is absolutely vital that you always keep in mind and not overlook it. Advanced prompt structure in 10 steps If the five-step structure isn’t enough for you, Claude’s creators also aim for a 10-step structure. It is like the first one we told you about, but more fragmented to give AI each and every detail what you will need. Each of these steps can be one or several paragraphs in the prompt that we are going to compose. You don’t have to do this every time, normally the previous structure is enough, but for particularly complex tasks can help you. … Read more

WireGuard, OpenVPN and IKEv2 explained without jargon

Let’s tell you why the protocol you choose is so important in one VPNand we will also explain three of the most important ones in detail. We will talk to you about WireGuard, OpenVPN and IKEv2, which you can find in services such as NordVPN or any of the best vpn serviceseven also in some free vpn. Let’s start by explaining to you what VPN protocols are and why they are so important. And then we will tell you what the protocols offer WireGuard, OpenVPN and IKEv2so you know which one to choose. We will try to explain all this in an easy and understandable way. Why protocol may matter more than other things When choosing a VPN, it is normal to look above all at practical aspects, such as the price of its subscription, the number of servers it offers and how many countries it has them distributed in, and even aspects such as the aesthetics and design of its application. However, We don’t usually pay so much attention to protocols. supported by each service, and it is something important. The protocol is the layer that determines the operation of the VPN itself. The one you choose can directly define aspects such as the speed or encryption strength of the connectionas well as other things like network stability, and how they manage potential network outages or transitions. Therefore, protocol shapes the VPN experience when you use it. There are several modern options here, such as an OpenVPN that offers great security, a WireGuard with faster performance, or IKEv2 that is perfect for mobile users. Which one to choose will depend on how you want to use the network and the purposes at all times. NordVPN with 76% discount The price could vary. We earn commission from these links OpenVPN is the industry standard OpenVPN has been the standard that dominates the VPN industry since its launch in 2001. He is the great veteranthat has enormous value for cybersecurity, since it involves two and a half decades of audits, testing in real environments, and reviews by security researchers around the world. Its main advantage is its flexibilitysince it can be easily configured to work on any port, using both UDP and TCP. This allows the protocol to work against restrictive firewalls, being a very good weapon against Internet censorship, as well as in blocked corporate networks where WireFuard or IKEv2 could be cut. As OpenVPN has among its modes the ability to operate over TCP on port 433, the same port used by normal https web traffic, it is impossible to block it without breaking general browsing. Use encryption AES-256considered indecipherable by current computing standards, so your traffic travels safely so that they don’t spy on what you do. The price to pay is in speed. Because yes, OpenVPN is that perfectly secure and private veteran technology, but it offers a slightly lower browsing speed than other alternatives. WireGuard is modern and fast WireGuard is the most modern protocol of the three we are talking about today, and its great asset is its extreme simplicity. Its source code takes up only about 4,000 lines compared to OpenVPN’s 100,000, and less code means fewer points where something can fail or get stuck, and greater speed. It also makes things much easier for audits. The most interesting part of this protocol is that it prioritizes simplicity and speed, but does not make sacrifices in security. It is open source, so anyone can review and use it, and uses various types of ciphers such as ChaCha20Poly1305 for packet encapsulation in UDP, or various cryptographic algorithms such as Curve25519 for key exchange, ChaCha20 for encryption, Poly1305 for authentication, and BLAKE2s for hashing. It is a carefully chosen selection of technologies. But where this protocol really shines is in speed, being able to reach quadruple OpenVPN connection speed in some configurations. It also maintains low latency in real-time activities, being the best alternative for gaming, streaming content or video conferencing. The only drawback that can be made is that it is not a protocol created for the general public, and that it stores IP addresses on the server during connections. However, most commercial VPNs that use it have created effective solutions, such as double NAT systems or dynamic IP assignment to maintain privacy. IKEv2 is perfect for mobile IKEv2 is a protocol designed for the mobile phone and the real life of conventional users. Specifically for those users who move from one place to another and connect to different networks. Its great asset is the MOBIKE protocol, which keeps the VPN connection active even when you change networks. Come on, if you change from home WiFi to your mobile data, your connection tunnel is maintained without you having to do anything. The other protocols can handle this as well, but MOBIKE was designed specifically for these scenarios. Another of the strong points of this protocol is in your connection timeswhich equals and even exceeds those of the competition’s protocols. Users typically connect within seconds, and reconnections after a network outage occur almost instantly. IKEv2 uses the AES-256-GCM encryption algorithm to offer maximum security. It also uses SHA-2-384 for integrity verification and 3072-bit Diffie-Hellmann keys. This security structure meets the strict requirements of companies and public administrations. In addition, IKEv2 also offers advantages in speed, security and stability. The Achilles heel of this protocol is visibility. It uses fixed ports and specific protocols, so it is easier to block than OpenVPN when faced with aggressive firewalls like those used by some countries to censor the Internet. Therefore, sometimes it doesn’t work well where other protocols do.

A comedian has explained what the song from ‘The Lion King’ means in Zulu. It was fake and could cost you 27 million

A Zimbabwean comedian went viral last month after claiming on a podcast that the Zulu phrase that opens the legendary theme song of ‘The Lion King’, ‘Circle of Life’ meant, simply and plainly, “Look, there’s a lion.” However, it was a joke: a false translation. Now the original composer, the South African Lebo M, is demanding $27 million from him in a federal court in Los Angeles. Aaaaa stork. Since 1994, millions of people have hummed “Nants ingonyama bagithi baba” without having the slightest idea of ​​its meaning. The phrase opens ‘Circle of Life’, the song with which ‘The Lion King’and is written in isiZulu and isiXhosa, two of the twelve official languages ​​of South Africa. The official translation used by Disney says: “Everyone hails the king, we bow before his presence.” It’s a Praise Imbongia form of oral royal praise poetry rooted in South African cultural tradition. Author, author. The song composed and performed by Lebohang Morakeknown artistically as Lebo M. Morake lived in exile in Los Angeles during apartheid. Hans Zimmer asked him to contribute his voice and his knowledge of African music to ‘The Lion King’ and the result was that initial scream that, as dawn broke on the savanna and the Disney logo rose, made the hairs on the back of the viewers of the time stand on end. The song was nominated for an Oscar for best original song and a Grammy, although it lost both to another piece from the same film, ‘Can You Feel the Love Tonight’. The false translation. In February, Zimbabwean comedian Learnmore Mwanyenyeka, known as Learnmore Jonasi, appeared on the ‘One54’ podcast. The presenters began to sing the phrase from memory, like every neighbor’s son does. Jonasi stopped them: “That’s not how you sing, don’t destroy our language.” He then offered his translation: “Look, there’s a lion! Oh my God!” When one of the incredulous drivers asked him if he was serious, Jonasi insisted: “That’s exactly what it means.” The clip went viral in a matter of days. The song that seemed like an epic proclamation was actually just pointing to an animal. The demand de Morake acknowledges that “ingonyama” can be literally translated as “lion” in Zulu, but argues that in the context of the Praise Imbongi The word functions as a metaphor for royalty and ancestral authority. Jonasi’s translation would be, in the words of Morake’s lawyers, “a manufactured and trivializing distortion, intended as a crude joke for personal gain.” According to the same legal document, Jonasi has been making this joke in his repertoire for eight years. Who is Jonasi? The comedian, born in Zimbabwe and based in Pittsburgh, rose to fame in 2024 when he placed fifth in that year’s edition of ‘America’s Got Talent’. His comedy usually revolves around the contrasts between his life in Africa and American culture, and part of his regular repertoire includes criticism of the representation of Africa in Hollywood, such as the lions in ‘The Lion King’ having American accents or the baboon Rafiki speaking English with a South African accent. The joke was, in that sense, consistent with his usual discourse of questioning how Disney had treated African culture. Can a joke cost 27 million? The legal key to the whole matter lies in a well-established principle in American law: the First Amendment protects parody and artistic satire, but not false statements presented as true, even if said in a comedic context. Morake’s lawyers argue precisely that: that Jonasi did not present his translation as a joke but “as authoritative fact.” The lawsuit also cites: Jonasi’s attempt to monetize virality through merchandising. The amount requested amounts to more than $20 million in actual damages, plus $7 million in punitive damages. It is alleged to justify it that the viral is directly damaging Lebo M’s professional relationship with Disney and reducing his income from royalties. Disney has not made any statements on the matter. The answer. Jonasi launched a GoFundMe campaign titled ‘Help Learnmore Fight an Unjust Lawsuit‘ with which he has raised more than 16,000 of the 20,000 dollars he asks for. There he says that he never intended to cause harm and that he needs support to “protect his right to speak and tell jokes.” Before that, posted a video on Instagram in which he declared himself a fan of Lebo M’s work and proposed making a video together explaining the real meaning of the song. In networks, the composer responded that Jonasi “crossed a line by insulting African culture and spreading colonialist propaganda.” In Xataka | We all assumed that ‘The Simpsons’ would never end. Now, its showrunner has just confirmed it

The length of “a day” on all the planets in the Solar System, explained in a revealing video of just one minute

The Universe is full of unknowns for humanity. What’s more, even data that we know ends up being questioned and reformulated, such as: the distances between planets in the solar system. In fact, as a millennial, when I was a child I learned all the planets at once and then I had to forget about Pluto. However, a reasonably solid and most interesting piece of information is How long is a day on a planet in the Solar System?information that on Earth is approximately 24 hours (23 hours and 56 minutes, specifically). This duration is due to the average time it takes our planet to complete a rotation on its own axis, although translation has an influence. Furthermore, it has evolved historically due to the gravitational pull of the Moon. Thus, and in general terms, we can establish that to estimate this duration, factors influence its radius, its orbit and also interactions with other celestial bodies. The reality is that we are facing a non-intuitive pattern with results that defy logic. To solve the question numerically, the popular science channel The Brain Maze has a great video the most agile and visual to clear our doubts with the figures in just one minute: Now we know how much, but it is even more interesting to understand why. As a summary, there are certain general rules that are met: paradoxically the largest planets are those that rotate the fastest and those closest to the Sun have suffered the effects of gravitational tides in such a way that they have slowed down to almost a stop. Although we already told you that there are quite a few anomalies. The counterintuitive pattern for determining how long a day is The Sun and the planets of the solar system. The sizes are to scale, but the distances are not. By Edits by Pepedavila.

When the Solar System formed, these early planets accumulated gas and dust with angular momentum. The gas giants captured so much material in a short time that they were able to preserve almost all of that original angular momentum. They go without brakes and it shows: it takes Jupiter less than 10 hours to make a complete revolution on itself, despite the fact that compared to Earth, it is more than 300 times its mass and 11 times larger. With Saturn this also applies, but for Uranus and Neptune the explanation is incomplete: the ice giants also spin fast for the same reason, but their history is much more eventful, either due to collisions or disturbances in the early days. On Mercury and Venus the days become eternal. The rocky planets close to the Sun found a brake in the tides. Mercury is so close to the star that its gravity has dissipated its original rotation over time. If you were on the surface of Mercury looking at the Sun, you would see it stop, move backwards, and move forward again: it is the effect of its elliptical orbit and its slow rotation, compared to its orbital speed. In fact, even has a double dawn in some parts of the planet. Venus is also slowed down by the sun’s gravity, but it also rotates in the opposite direction. Because? Good question, for you, for me and for science in general: it remains a mystery, although there are hypotheses. A curiosity to reinforce the rarities of Venus: a day lasts longer than its own year, it takes 243 Earth days to rotate on itself and only 225 to complete its orbit around the Sun. By the way, the fact that a day on Mars and on Earth lasts practically the same is, according to science, almost certainly a coincidence. This similarity and other factors have fueled for decades the idea that Mars is the ideal candidate to host life.

8 GB of RAM has gone from $40 to $130 in five months. It is explained in four words: “It is what it is”

At this point in the film, it no longer escapes us that we are in the midst of a new component crisis. What started with RAM crisis ended up mutating into SSD crisis and any device that has memory or a memory controller. We are in an “unprecedented” situation, said by the companies themselves that manufacture that memory, and although it all started with SSDs and more expensive RAM ‘chips’, now things have escalated. How much? Let’s go with some examples. a rocket. Maybe in Europe they are not the best known, but Framework It is a company that is doing things well. It has a desktop PC, but also something much more interesting: modular laptops. It is not so common to be able to choose all the components of a laptop, and the Framework components do give us that opportunity. The fact is that they are the perfect example to see how the market is. In September they stopped selling standalone RAM modules. They were not the only ones who began to sell computers without memory or with less physical SSD than advertised, but now the next ‘stick’ has arrived: if before 8 GB of RAM cost 40 dollars, now it is 130 dollars. And if you wanted 96 GB of RAM, before it “only” cost you $480… and now you have to shell out $1,340. It’s the market, friend. It is estimated that prices are increasing between 6% and 16% on the company’s equipment. The Framework Desktop 32GB LPDDR5X memory is up $110 since it launched. And the 128 GB one has increased by about $600. The equipment that was already built in the warehouse has not been affected by this, but as the stock runs out, they will inevitably follow the same path. “The price is what it is, unfortunately,” says the CEO of Framework In ArsTechnica we can read that Nirav Patel, CEO of the company, points out that they are trying to solve the problems, but in the end… he is not on his own and the best thing he can do is be transparent. In an interview with BIpoints out that they are looking under the rocks and that if an intermediary tells them “we have found 5,000 RAM modules in a warehouse”, they would buy them without thinking. The problem is accessing new RAM modules… because there aren’t any. Increases. As we say, it is no longer just the RAM that we can see in stores like Amazon, but the components of a computer, a cell phone, a television, a cara modem or… one Raspberry Pi. Since this crisis began, we have talked a lot about how manufacturers were saying that things were tough and it was going to take a while for the market to recover. But the case of Framework helps ground things, and so does Raspberry. Because if Framework uses DDR5 memory, which is the most advanced, Raspberry’s is not the latest generation. However, the company has also had to raise prices. Yes three months ago increased a little, now they have skyrocketed. Its memories are LPDDR4 and the company has published a table that point Because the more RAM your board has, the more the price goes up. Raspberry PI 4 and Raspberry Pi 5 Price increase 1 GB Nothing 2GB 10 dollars 4GB 15 dollars 8GB 30 dollars 16 GB 30 dollars Out of the race. In the end, it all depends on the price of the device. In a 4,000 euro computer that you need for professional work, you have no choice but to pay about 600 more to expand the RAM. But on cheaper equipment, the feeling is that it has a much greater impact. This is the case of the Raspberry. In a 120 euro device like the Raspberry Pi 5 of 16 GB, an increase of 60 euros is stupid. And as the situation lasts a long time, that will be the big problem for many software manufacturers. Apple just present new laptops and the iPhone 17e and, in Spain at least, the price has remained the same. This has not happened in other countries such as the United States, seeing strong increases in some models. Apple, Lenovo, Dell… are companies that have already said that things are bad and the users will have to bear the cost. But there are also voices that point out that not all companies can allow their users to be the ones who ‘swallow’ with the situation. From SMICChina’s large foundry, has already pointed out that there will be hardware companies that will be left out of the game. We are already seeing it: the cheap mobile is suffering the consequences and the Chinese Meizu, which wanted to eagerly return to the Western market, is already backing down. 2027 2028. Valve and its Steam Machine is another example: the console should come out this spring, but not only is there no price, but it is not known when it will arrive. And when will the end of this catastrophic situation be? It’s the million dollar question. Patel comments that the relief will begin in early 2028, a date similar to what other parts of the industry are managing. However, Jensen Huang, CEO of NVIDIA, has already warned that the AI ​​race He has seven or eight years leftand just now they have begun to commission TSMC to begin mass manufacturing of Vera Rubin, their next-generation acceleration platform. It is something that needs memory and only Samsung and SK Hynix (two of the big three RAM companies) are able to supply it right now. In the end, it is about going day by day in this new crisis, but everything indicates that if we need something, it is better to buy it as soon as possible because ifamsung, Micron and SK Hynix they are not doing consumption memoryprices will rise more and more over the next few months.
