The “Death whistles” Aztecs were always a mystery. Until we discovered why they give us so many chills

The “Death whistles” Aztecs have surprising peculiarity: their intimidated appearance, but much more does its sound. Although the artisans manufactured them in the shape of a skull and figures that are today interpreted as references to Mictlantecuhtlithe Aztec King of the underworld, it is his loudness that has been intrigued by archaeologists for years. Not surprisingly if one takes into account that when we take one of these instruments to the lips and blow, something occurs similar to a human cry. It’s hard to listen to it without feeling uncomfortable. A group of researchers wanted to go further and investigate why we feel what we feel when we listen to the whistles of Aztec death. The answer can be key to understanding a piece that is still involved in mystery. Death whistles? Exact. His name imposes, but not as much as his appearance and sound. The “Death whistles” Aztecs are instruments made with clay between three and five centimeters and skull form, a peculiarity that experts interpret as a reference to Mictlantecuhtli, the lord of the underworld. They also include Figures of the Snake of Fire and Owls. Experts believe that the original pieces were manufactured Between 1250 and 1521. Wars or rituals? The first references about them date from End of the 19th centuryalthough probably the most famous specimen was found between 1987 and 1989 in the Ehécatl-Quetzacóatl templein Mexico City. There the archaeologists located the skeleton of a human sacrifice with a whistle, which has given wings to the different theories that try to explain what they were used for. There are those who think that the Aztecs used them in wars to scare their enemies and who believe that their use was basically ritual and symbolic. According to them, the sound would accompany the dead on their trip to Mictlánthe Aztec underworld. To that last theory contributes that death whistles have been found in places where ritual burials and human sacrifices were made. Another interesting clue is that the piece located next to the skeleton recovered in Ehecatl-Quetzcalcóatla circular sanctuary dedicated to the god of the wind, Ehecatl. Today several copies are preserved in facilities of the National Institute of Anthropology and History (INAH) or the Berlin Ethnological Museum. And how do they sound? Here are A few examples So you can check it. Depending on how they are used, whistles produce a siseo or a much deeper, intimidating sound, similar to a human cry. Recently a group of researchers from the University of Zurich (UZH) set out to go nevertheless and answer two big questions: why do they sound like they sound? And why listening to them produces such an overwhelming feeling? Their conclusions were reflected in An article Posted in November in Communications Psychologya magazine of the prestigious Nature Group. How have they done it? With a combination of techniques. The team obtained recordings from several whistles, including two recovered in Tlatelolcohe performed computerized tomographs To create 3D objects and resorted to replicas of whistles made of artisans with clay simulating the characteristics of the originals. Then they registered the sounds and reproduced them to a group of volunteers. To document their reactions well, scientists submitted them to a neuroimaging study. The objective: find out how their brains reacted. What did they find out? To start they discovered that the whistles have “A unique internal construction”with two opposite cameras that generate turbulence in the air and produce that kind of shout that, if archaeologists are right, accompanied the ritual victims in their descent to the underworld. “The whistles have a very unique construction, and we do not know any comparable instrument of other pre -Columbian cultures or other historical and contemporary contexts,” Explain Sacha Frühholz, the professor of cognitive and affective neuroscience who directed the study. The Aztecs are also known for making instruments that imitated the sound of the wind or the songs of the birds. What did they feel when listening to it? That is the most interesting part of the research. The volunteers described the sounds as “extremely chilling and terrifying”, According to verifies The UZH. “The brain regions belonging to the affective neuronal system responded strongly to the sound, which once again confirms its intimidating nature. The team also observed brain activity in regions that associate the sounds with symbolic meaning.” In summary, the volunteers called him “very negative” and “frightening.” “Given the aversive/terrifying and associative/symbolic sound nature, as well as the locations of the excavations known in places of ritual burial with human sacrifices, its use in ritual contexts seems very likely, especially in rites and sacrificial ceremonies related to the dead,” They conclude The experts, who recognize in any case a handicap of their experiment: the test was done with listeners of modern Europe who did not know that they were going to listen to the sounds produced by the old Aztec instrument. Did they find out anything else? Yes, something interesting. The volunteers perceived the sounds of whistle as hybrids, between the natural and the artificial. “They were classified at the psychoacoustic level as a hybrid mixture of voice sounds and screams, but also caused by technical mechanisms,” says research, which slides that this double quality could influence the reaction of the listeners: sound evoked shouts of a human nature, but also tones generated with artificial objects.

Ryanair has left several death injured in Spain. Now we know that he has more passengers than ever

Ryanair is not weighing, at all, his departure from some Spanish airports. The Irish company is flying more than ever in our country, as certified by the data related to the first semester. The company accumulates more passenger volume in Spain, is one of the airlines that grows the most and expands its distance from competitors. More passengers, more. In the first semester of 2025, Ryanair has accumulated in Spain 32.64 million passengers. It is a 6.6% higher than that registered in the same period last year when it accumulated 30.63 million passengers. It is, with great difference, the airline that moves more traffic from our country. The data collects them AENA which also points out that in the first semester more than 181 million passengers have moved at Spanish airports, the figure is 4.7% higher than that registered in the same period of 2024. Leaders. The data of the first semester of the year also leave other readings. Ryanair has added more than two million passengers compared to the same period of 2024. No other large airline has grown so much in our country in absolute terms of travelers. In fact, the variation with respect to last year is 6.6%, lower than the sustained in previous semesters and also lower than other companies Lowcost such as Easyjet (+13%), Binter (+8.6%) or Wizzair (+22.8%). However, none of them approaches the numbers of the Irish company. A year ago, Ryanair surpassed Vueling in 8 million passengers in a single semester. Today that difference is closer to the 10 million passengers since the Spanish airline has only grown in some 400,000 travelers compared to the first semester of 2024. In full withdrawal. Growth is even more striking if we consider than Ryanair has closed 12 routes in Spain And now offer 800,000 places less than only a few months ago. The company fulfilled its threat to leave some regional airports as a demonstration of force before the fine that the government imposed For the collection of hand luggage, practices that the Executive considers abusive. At his departure, Ryanair prioritized regional airports. In them, their business volume was low and, in fact, maintained some routes for Commercial agreements with local entities. He knew that retiring from these spaces could cause almost deadly damage to some airfields. To show that of Valladolid that in the first half of the year he has registered 41,725 passengers between January and June, about 56,000 passengers less than in the same period of 2024 when 100,000 travelers were toured in six months. The Lowcost. The other striking fact, which we have already advanced, is the growth of the Lowcost in front of any other company. Regarding the same semester of 2024, no airline grows both in passengers and the cheapest options. Airlines that make greater reach flights are more sensitive to geopolitical fluctuations and facilities (or not) to travel. Iberia, for example, Avaca Its 0.7% setback to a fall in travelers to North America. On the contrary, Eurowings (Lowcost from Lufthansa) and Transavia (from Air France-KLM) have also grown in Spain more than 4%.

Falling from 10,000 meters without parachute was a safe death. Until Vulović appeared

Suddenly, the hostess Vesna Vulović Recover knowledge. He is bite and can barely move due to his partner’s inert body. Half of Vesna remains on the plane, and the other half is out. What had just happened was going to challenge physics for decades: no one, neither before or after, had been able to survive a free fall without parachute from 10,000 meters high after the explosion of a commercial flight. The question since then is simple: how the hell managed to leave alive? The wrong flight. On January 26, 1972, Vesna Vulović, a young 22 -year -old Yugoslava flight Jat company for a confusion of names with another partner. The itinerary included several scales between Stockholm and Belgrade, and nothing presaged that it would be the most extraordinary and tragic flight of his life. The accident. After taking off from Copenhagen to Zagreb with 28 people on board, the plane reached cruise altitude. Minutes later, at 4:01 p.m., while the then Eastern Germany, He disappeared from the radar suddenly. An explosion at the front of the luggage compartment left the McDonnell Douglas DC-9 in two to more than 10,000 meters high. What followed was a brutal vertical fall, a bleak scenario in the snowy mountain of Srbská Kamenicein the then Czechoslovakia. There was only one survivor: Vesna. Silence: an attack. Just a few hours after the accident, Czechoslovacos secret services They took control absolute of the place. Access to press was not allowed, much less civilians. The next day, an unidentified man, in a somewhat strange Swede, called the Kvällsposten newspaper ensuring that he was Croatian and a member of a nationalist group that had placed the bomb. The Yugoslav government immediately pointed to The UstachaCroatian ultra -right organization. Ten days later, the remains of a alarm clock supposedly linked to an explosive were presented as proof. Black boxes were never found, there were never arrests, or claims by any organization. An McDonnell Douglas DC-9 by Jat Airways identical to the accident The documented miracle. As we said, the official report indicated the cause of the accident Like a bomb placed by a Croatian nationalist group, although the culprits were never identified. Even so, the authorities closed the case in 1974 attributing it to an explosive attack. The official story argued that Vesna fell from More than 10,000 metersprotected by a series of improbable factors: a catering cart that kept it trapped in the fuselage, the friction of the air that damping the fall and the so -called terminal speed (maximum speed that reaches a body moving within an infinite fluid under the action of a constant force), the snow on the slope of the mountain that reduced the force of the impact, and finally a part of the relatively intact plane protected from the final blow. That was so amazing that even the mythical Mythbusters reached Recreate the case And they concluded that the possibility of surviving was not void, although, of course, tiny. Tributes. Vulović suffered multiple fractures, entered a coma for almost a month and was temporarily paralyzed from the waist down. However, he managed to recover, walk again and even fly again. In fact, the woman was honored in London By the book Guinness With a record that remains: that of the person who has fallen without parachute and has survived (prize, by the way, delivered by Paul McCartney himself). The doctor. Over the years, Vesna shared Some memories rebuilt from what they told him. In her words and those of the man who rescued her, a former German army doctor named Bruno Henke, she was in the central part of the plane, not in the tail, contradicting the official theories that explained their survival. Henke, a neighbor of the area, argued that he found it in the middle part of the plane, at the height of the wings. He found her head down, with the torso out of fuselage and legs inside. Vesna always He believed his testimonyIn fact, he had a close relationship with Henke. Vulović (right) during his visit to Czechoslovakia, November 1972 Something does not fit. Let’s recapitulate: Vesna’s body, as we said at the beginning, was partially inside and outside the fuselage, with that “miraculous” cart literally nailed to his back. And here appears one of the great doubts, because that incongruity undermines the physical hypotheses about how he could survive, since a person in the middle zone of the device could hardly have remained within it After an explosion that left it at two high. Herself He pointed out thatas the plane was half empty, it probably moved among the passengers, according to the service protocol. To do everything a little more complicated, Vesna’s amnesia about everything happened on that date prevented verifying the details. Boom. In 2009, the story He took a turn unexpected. An investigation by journalists Peter Hornung-Andersen, Pavel Theiner and Tim Van Beveren, published by Tagesschau and issued by the ARD chain, He unearthed documents Dak For mig fighters of the Czechoslovak Air Force when it flew to low height, just 800 meters from the ground. According to This versionthe plane descended by an emergency and was confused with an aerial threat when entering a restricted area, perhaps linked to a Soviet missile base, or coinciding in the airspace with the plane of the Soviet leader Breznev’s own leader in official visit to East Germany. The demolition would have been Undercover by the Police Secret, which built the history of the “world record” to hide the incident. This version was based on official documents, testimonies of witnesses who saw the plane flying whole before exploding, and what is doubtful, the apparent physical impossibility of surviving a fall from such a height. The official silence. Czech authorities They denied categorically the alternative version without offering contrary evidence. They never explained the absence of black boxes or responded with documentation to refute the new findings. A general came to declare that “at least 200 people should … Read more

At his departure from Valladolid, Ryanair has left an unexpected death injured: airport coffee

Ryanair’s impact is not only counted by the number of flights he leaves in an airport. Not at least where they are a key piece in the operation of a regional square such as Valladolid, where Its march has reduced by 60% The number of travelers who pass through their facilities. Last January, the company announced that this summer would close operations at the Valladolid airport. The decision entered into the Pressure measures that the company is applying against the government for discrepancies related to the collection of hand suitcases or rates that Aena Cobra for operating in the facilities. This pressure tool translated into a reduction in operations in seven airports. In Vigo, for example, Ryanair has eliminated their seats by 61% available. But the highest figure is not always the one that does the most damage because you have to pay attention to the specific impact that the company has on the airport. And in Valladolid it was huge. So much that the volume of travelers at the city airport has been reduced by 63.2% According to data offered by AENA. But the company’s march not only has a direct impact on the offer of flights that are now available the Valladolid. It impacts the workers of the airport itself. Like those of its cafeteria. Three workers dismissed due to lack of work The story brings it first hand The North of Castile. The local media has interviewed César Carreras, a cafeteria dealer of the Valladolid airport who says that with the march of Ryanair, 80% of the clientele has vanished. In less than a year, Carreras has seen how the airport was emptied without Ryanair’s operations (which stopped operating on March 28) but with The previous flying of Vuelingwhich stopped offering the Valladolid-Barcelona route in June last year. Right now, Binter is the only company that operates the airport but has no daily trips. “This month They only work two days a week“, says the head of the cafeteria. Specifies that travelers have left but that there is also an employee hole, since only four workers of all employees that the company maintained in Valladolid remains in the facilities although performing other work. He explains that only the days that there are flights and just for three hours are exploding to cafeteria because the rest of the day the airport remains practically empty. He explains that now he only works the cafeteria and that he has had to fire three employees. At the moment, it remains in the concession because it would have “problems” to leave it and because it can give the service itself since it has another open business. When Ryanair announced that Valladolid left and Jerez and what reduced its operations I already talked about the decision would leave “Half -empty regional airports” although he blamed the march and reduction of operations to the alleged high rates of Aena. Those Aena rates They are the ones used to maintain the minimum services of an airport (security, cleaning …) and from the company ensure that they are extremely low in regional airports because there are multiple discounts to make them attractive. At the moment, they say, they are operating just two euros per passenger. What has long resonates is the fine that the Ministry of Consumption imposed on Ryanair for the collection of the hand luggage suitcase. For the Government, the allowed dimensions are extremely reduced and do not cover the definition of “essential” to which it obliges European regulations. Consequently imposed a sanction of more than 100 million euros. That fine was the one that precipitated everything, since Ryanair understands that without a more concrete definition he has no reason to let in the cabin that They exceed 40x20x25 cm measures collected in its most basic rate. Therefore, they assure that the collection for the cabin trolley It is perfectly legal. Something that seems, It will be ratified in a few months by the European Union itself.

Huawei is China’s winning horse and is even leading where he seemed to death: in mobiles

2025 will not be an easy year for telephony. The consultants They are checking down Growth forecasts of giants such as Apple and Samsung, hoping that the geopolitical impact of the commercial war will translate into higher prices in key markets such as the United States. The growth perspective in global shipments is especially low, and will be mainly starring Chinese manufacturers. Among them, there is one in which all expectations are set. One with the potential to shake the industry. All eyes put in Huawei. There is no worldwide manufacturer that grows more shipments than Huawei. It is something that We warn at the beginning of the yearin a global photograph of Canals that showed some interannual contraction for Apple and Samsung numbers (they lost 1% compared to 2024), and in which Huawei grew no less than 36%. A wild figure, taking into account that its local rivals such as Xiaomi, Honor or Live grew by about 15%. Less than half of what Huawei was achieving. An unstoppable trend. Ethan qiAssociate Director of Canalys, expects the Chinese manufacturer to remain a leader for 2025. Although not much further in its analysis regarding the relaxation of bottlenecks so that Huawei can stock up on critical components, there are several key points that explain why the Chinese company has all ballots to lead world growth this year. Among them, how will tariff pressure, Chinese technological nationalism of Huawei consumers play in favor of Chinese companies, The thrust with SMIC for the manufacture of Kirin chips and the turn Towards a domestic supply chain for close the circle. Without fear of own hardware. After the American veto, Huawei has focused all its efforts on achieving a product without external dependence. And he has achieved it. Huawei Mate 70 was the company’s first phone with Kirin 9020, A chip developed in silence and who planted the United States, a country that could not understand how were 5g chips developing despite the sanctions. Although this processor is manufactured under the lithographic process of 7 NM of SMIC, and notably below those manufactured by TSMC with its N3E lithographythe demand for mate 70 It has been high in China. However, if Huawei wants to continue pushing on national soil, he needs to prioritize a very concrete product: the mid -range mobile. The mid -range as a key. In Spain we are not the only ones who bet on quality-price mobiles. At the beginning of 2025, the Chinese demand of smartphones concentrated on the strip of 2,000 to 5,000 yuan (240 and 609 euros to change). Here Huawei places his Nova rangeone of its main sales engines in China. National policies of Subsidies Sales continue to warm up of smartphones, having added two to three percentage points to their growth in the first quarter of 2025, according to estimates. Huawei, together with the support of its local suppliers and SMIC, is at its best to aim with this family of products to its national soil. All to pure 80. Although the growth of Huawei in China will depend on a good part of the efforts that focus on their best -selling ranges, all eyes are now put on The pure huawei 80his Flagship family and a great opportunity to demonstrate what their efforts are being materialized to achieve self -sufficiency. They will be presented on June 11, and They already have more than 200,000 reservations without even having gone to the market. The great hope. Huawei’s role is key in China. He is not just the protagonist in the race to lead the manufacture of smartphones with SMIC, It is because of its potential to create chips for iaas his family Asce 910. This chip will play a key role in the effort for reduce national dependence with American manufacturers such as NVIDIApointing in front of their A100 and H100. Presumably, SAQC technology will allow SMIC to manufacture 3 Nm chipswhile they would be About to achieve capacity to make 5 Nm chips No need for access to equipment extreme ultraviolet photolithography asml. A way to travel that leads to an inevitable destination: sooner or later, China will be the world chips leader. Image | Huawei In Xataka | Best Mobile Huawei (2025).

The US will revoke the visa of Chinese students to protect their AI industry. The risk is that he ends up wounding her death

China is by far the largest world graduate producer in Stem races (Science, Technology, Engineering and Mathematics), both in absolute and relative terms to the global total. The phenomenon is an exceptional magnitude, but there is a country that has just been slaughtered in their noses: United States. What happened. As they pointed out In The New York Times A few days ago, the US Secretary of State, Marco Rubio, advertisement that the Trump administration “would aggressively revoke” the visas of Chinese students. In these visa cancellations, those students with ties to the Chinese Communist Party (PCC) or those who study “critical fields” that did not define clearly but probably include that of AI will be included. Source: The New York Times. Impact. In 2024 in the United States, 20% of the visas granted to students went to young Chinese students. The measure is worrying for American universities, which depend on international students who pay the full cost – without scholarships – for their annual income. In addition, this decision affects both students who want to ask for a visa from now on and those who are already studying in the country. In total there are about 275,000 Chinese students in all types of university careers. Uncertainty. It is not clear what criteria will be followed to revoke these visas and not as quickly these measures will begin. Nor is it known if China will retaliate, although the number of US students in China is much less significant. In 2020 USA He already expelled to 1,000 Chinese students with ties with Chinese military schools. A massive practice. A report Published by the State Department and the NGO called the Institute of International Education indicated last year that China was the second country with the highest share of international students: only India “exports” more students. In the 2023-2024 COURSE, it received 1.1 million international students, of which 331,000 came from India (23% more than the previous year) and 277,000 from China (4% less than the previous year). Source: CSET. China is absolute power in Stem. If there is a “graduate” graduate producer “(science, technology, engineering and mathematics), that is China. Collected data By cset They reveal that in 2020 China led the number of graduates in these disciplines, with a total of 3.57 million students. Only India approaches with 2.55 million students, but for example in the US the figure is four times lower than in China: 820,000 graduates. Source: CSET. And the one that is most dedicated to these disciplines. Not only is it that China has the greatest number of Stem graduates in the world: it is that the percentage of students who choose these disciplines is also the largest in the world. 41% of students are launched to Stem Carreras. They are followed by Russia (37%), Germany (36%, Iran (33%) and India (30%). In the US, only 20%of students bet on scientific careers. Source: Macro Polo / Paulsen Institute. And that includes AI. In People’s Daily They pointed out A few days ago how approximately 50% of the main researchers of AI are trained in Chinese universities. The worrying thing for the US is not that: they depend a lot on them. A report of the Paulgo Institute of Chicago (USA) recently revealed that 38% of AI experts that develop their professional career in the US They have formed in Chinese universities. They are in fact more than those who have a strictly American origin (37%). China does not stop betting on Stem Education. Between 2012 and 2022 the budget spending of the Chinese government in education increased from 2.2 billion yuan (268,167 million euros) to 4.85 billion yuan (591,187 million euros), more than double. Several Chinese elite universities They have announced His intention to expand his curricula with the objective of prioritizing the strategic needs of the country, and here the AI ​​- who You start teaching in schools– It’s key. Imminent danger. This domain has a direct impact on the capacity of innovation, technological development and industrial competitiveness of China, but also of the countries that allow Chinese students to study and then work in international companies. Cut your wings to that talent is to cut them to innovation. The US will get just the opposite of what it intended. The analyst Alberto Romero explained How these measures are probably designed to protect national security – which Chinese students do not end up “spying” for China. “However, instead of helping the US to enhance their industry, what can happen is that they weaken it. Not only that: that revocation of visas can precisely help China meet their strategic objectives. Nvidia already notified with the hardware. The US opted to veto the export of its advanced chips from AI to China. The shot has come absolutely for the cylinder headand instead of preventing Chinese development and innovation, it has put a rocket. They do not seem to have learned the lesson, and revoke the visas to Chinese students can end up being an even bigger shot that comes out of an even bigger cylinder head.

We have discovered a relationship between olive oil and risk of death by dementia, a point in favor of the Mediterranean diet

Someone could think that everything is already said, all investigated, on one of the fundamental axes of the Mediterranean diet, olive oil. Nothing is further from reality: research on this food continues and continues to reveal striking aspects of the liquid. And as regards striking relationships, perhaps the palm is taken by the fact that they keep the consumption of this derivative of the olive and dementia. 28%. A study published a few months ago established existence of this relationship. Specifically, the analysis responsible for the analysis observed a 28% reduction in the risk of death associated with dementia between people who consumed at least Seven grams of olive oil per day, compared to those who did not consume this liquid or did it rarely. Until now, some studies They had indicated us an inverse relationship between the Mediterranean diet and the cognitive deterioration associated with age. From there, establishing relationships between different aspects of these variables can help us better understand the link between Mediterranean diet and healthier aging. Changing ingredients. In its analysis, the team also studied the effects of replacing different sources of fat. Through a substitution modeling, they estimated that replacing five grams of margarine or mayonnaise daily with an equivalent amount of olive oil could be related to a decrease in the risk of mortality associated with the dementia of between 8% and 14%. A similar analysis did not detect similar effects when these fats were replaced by other vegetable oils or butter. 92,383 participants. The study was conducted from the macro -conformation Nurses’ Health Study II and Health Professionals Follow-Upwhich allowed to obtain Information about 92,383 participants. These filled surveys on eating habits every four years over a 28 -year period. The team divided these participants depending on their olive oil consumption: those who never consumed olive oil or did it less than once a month; who consumed up to 1.5 grams per day, who consumed between 4.6 and 7 grams per day; and a group for those who consumed more. The team extended its analysis over 18 years of the study and controlled aspects such as the general quality of the diet or the genetic predisposition to suffer from the disease. The details of the study were published In an article In the magazine Jama Network Open. What is happening? When establishing a causal relationship, it is always convenient to understand what mechanisms are operating behind this relationship between olive oil consumption and death risk associated with dementia. “Olive oil is rich in monounsaturated fats and contains components with antioxidant activity that can play a protective role for the brain,” He explained to the environment UPI Anne-Julie Tessier, co-author of the study.

The death of the Custom Roms was inevitable

There was a time when customizing an Android mobile was popular, very popular. I remember the fervor of the Custom Roms, the movement that was in Spanish forums such as Htcmania In Roms sections, and how Xda Developers It was a bible for the pot. Increasingly polished systems, obstacles by manufacturers so that users do not personalize the phone, and Middlek boom and its consequent incompatibilities with drivers have ended up making this paradise a whole moor. The golden age of the pot. Talk about Custom Roms boom It is to go back 10 years ago, between 2010 and 2015. During this period, the community of developers and users willing to put hand to their device. We always talk about small numbers, at that time Cyanogenmod (the best known rom) exceeded one million users. Spectacular number for such a niche product, but minimal compared to the thousands of users that Android has. The big names. There are several names that will put the hair from Punta to more than one regular at the Custom Roms. AOKP (Android Open Kang Project), Resurrection Remix, Paranoid Android, Carbonrom, Dirty Unicorns … All of them had in common that they were based on “pure Android”, the Android AOSP code with its native visual lines. Each of them added different degrees of customization, some to brutal extremes. Years later, with the launch of the Google Pixel, the Rom Pixel Experience was popular, I still have installed in me Little f3. This ROM carried the pixel system to phones with other systems, adding additional customization that even Google allowed. Deaths begin. Little by little, most of these projects have died. AOKP died in 2018Resurrection Remix carries Without climbing anything to Sourgeforge from 2020, Dirty Unicorns turned off his servers in 2021last year We said goodbye to Pixel Experience. Of the few survive are lineage (former Cyanogenmod), with quite updated ROMs and giving a second life to those phones that no longer have official support by the manufacturer. And it makes sense. Changing ROM has, mainly, two advantages. The first is to enjoy the latest version of Android before the official manufacturer gives us, if it does. But, for a few years, this is no longer of interest. Android’s versions come with more and more discreet changes, and move from Android 13, to 14 or 15 does not involve draft changes. More advantages. The second advantage is customization, something that manufacturers have been working for a while. There are terrible roms (we are not going to give names, it is known), but there are also manufacturers making very good quality software and with a magnificent support. Third, the bookstores and APIs of the manufacturers have more and more weight: the cameras pay as pay thanks to the behavior of the NPU, native integration of AI … Elements of closed code to which we dispense if we work on a generic kernel. A perfect cocktail for a terrible outcome: the death of the Custom Roms. In Xataka | I’ve been trying mobile for 10 years and this is the only customization layer that has managed to convince me

Skype had everything to master the video calls. Now Microsoft has just put a death date

It has been Xda Developers who advanced the news that Microsoft has just confirmed publicly: Skype is going to be closed forever. It will happen in May, when they put the final brush to a story that could be very different and that will now be an inherited inherited by Teams, the company’s right eye for communications. It seemed a long time since Skype’s end was imminent. It was released in 2003 and Bought by Microsoft in 2011 for 8,500 million dollarsfigure that then seemed astronomical. Skype was a before and after. He turned the calls and long -distance video calls into something accessible to anyone with the Internet. It became the metonymy of video calls (“Do we make a skype?”), Something that very few products achieve. But Skype’s story is rather that of a wasted opportunity. He had everything to become a dominant platform: He arrived very soon to the market. He had a great adoption. He had a recognizable brand worldwide. And I had behind Microsoft’s resources. However, bad decisions and a lack of constant innovation allowed rivals such as Facetime, Zoom, Google Meet, Discord or WhatsApp a toast. Seen in retrospect, Skype’s decline was not sudden, but gradual. In 2015 It was integrated in Windows 10but the experience was unnatural. For a long time, Microsoft maintained a strange duality between Skype and Skype for Business. The latter was replaced by Teams in 2019. Meanwhile, others advanced quickly. Zoom catapulted during the confinements of 2020 thanks to the juncture, but also thanks to simplify: he eliminated records of records and downloads. Facetime was completely integrated into the Apple ecosystem. And WhatsApp took advantage of its omnipresence and popularity to offer them as one more service. And meanwhile, Skype was stagnant in a cycle of redesign who never solved his main problems (Sometimes they magnified them): An inconsistent interface, performance problems and a confused user experience. Microsoft is not only killing Skype, it is redirecting its users towards Teamsincreasingly popular. Skype users can use their credentials to access Teams and there they will see their contacts and conversations. During the transition period, users of both platforms can communicate with each other. Then there will only be space for Teams. A bittersweet end. A closure that seems almost merciful. Skype lived in his own confusing identity. It remained as that application that we had installed “just in case” and that we do not remember the last time we used it despite the fact that at the time it played a fundamental role. Being able to see and talk to other people in other countries was revolutionary in the 2000s, Skype leaves A great cultural impact that is now transformed into archeology. As a final gift, a lesson leaves us: it does not matter if a platform is very established, it can become irrelevant if it does not evolve to the compass of the needs of its users. End of an era.
