assault in sound quality and for being the most comfortable headphones

by

Now that Samsung has finally announced the new generation of its headphones, what better way to explore what they offer than to compare them with models from other brands. Are they better than Apple’s? To do this, in this article we are going to put the Samsung Galaxy Buds4 with AirPods Pro 3. The differences between the Samsung Galaxy Buds4 and the AirPods Pro 3 The design, which one do you prefer? It is evident that one of the most important points when using headphones is the design. The Samsung Galaxy Buds4 they have a open, padless design while the AirPods Pro 3 They come with a set of five pads. And this may interest you a lot when buying headphones or others. Each person is different and headphones may be good for one person, but not for you. The good thing about AirPods is that with the pads you can customize the headphones so they fit better in your ears. Samsung does not allow this as it has an open design and no pads, so in the worst case you could feel some discomfort if they are too big for you or they simply fall off when walking, running or exercising. Best for lossless audio The AirPods Pro 3 may be the perfect headphones for an Apple user, but not everything is pretty: the headphones support the AAC codec (256 kbps), so if you use platforms that offer ‘Lossless’ sound quality you will not be able to have the best possible experience. Things change with the Samsung Galaxy Buds4 that support the codec SSC-UHQ (24-bit / 96 kHz). In this case you can take advantage of the ‘Lossless’ quality offered by many platforms such as Tidal or Spotify. If you are looking for the best possible sound quality, these are the ones that may interest you the most. Samsung wins in autonomy, but with nuances Both the Samsung Galaxy Buds4 and the AirPods Pro 3 offer good autonomy, up to 30 hours for the former and up to 24 hours for the latter. But if we remove the charging case from each one, things change. If you have active noise cancellation on, the Samsung headphones will last you just under five hours, while with the Apple headphones almost you will be able to last almost an entire day of eight hours of work. This is not to say that Samsung headphones are worse. Simply you have to take into account when you are going to use them: If it is for training or listening to music for a few hours, Samsung headphones may suit you well. If you listen to music for many hours to work, Apple headphones win here. What happens if my headphones get wet? Although it is always better to avoid water to ensure proper functionality of the headphones, both the Galaxy Buds4 and the AirPods Pro 3 are water resistant, although not in the same way. Resistances are usually measured by the degree of IP certificationand in this case the headphones come with: IP54 certification on the Samsung Galaxy Buds4: protection against water jets. IP57 certification on AirPods Pro 3: protection against complete immersion in water at a depth of 1 meter for 30 minutes. In any case, both headphones are durable enough to function properly when used while exercising or in the rain. In the event that, for example, they fall into a puddle of water or into the bathtub, the AirPods Pro 3 are protected for these situations. A little extra that can change your choice Although it is something that we can find in other devices such as smartwatches, it is worth mentioning that the AirPods Pro 3 have a sensor that we do not see in Samsung headphones: the heart rate sensor. It is not a simple addition that we are going to avoid because we already have a watch, since there is a good reason why Apple has decided to introduce it in headphones. Beyond the reliability provided by sensors in devices such as smartwatches, it is medically more reliable for a device to take vital signs from the ear than from the wrist. If you exercise and are looking for greater control over the measurements, this AirPods sensor may interest you. In summary: which Bluetooth headphones to choose according to your tastes and needs Why choose the Samsung Galaxy Buds4 The Samsung Galaxy Buds4 arrive in style, offering a very competitive price. Where they stand out the most is in: Your SSC-UHQ codec. If you are going to use them to listen to music on platforms that offer ‘Lossless’ quality, these are the ones we recommend. If you listen to music sporadically. The headphones alone have less autonomy than Apple’s, but with the charging case they get a higher figure. If you use them for sessions of no more than four and a half hours, these are the ones that may interest you. If you want the cheapest. It is inevitable to compare prices on these headphones, so if you want to spend as little as possible, the difference of 70 euros is quite attractive. The price could vary. We earn commission from these links Why choose AirPods Pro 3 The AirPods Pro 3 were launched a few months ago and continue to be one of the best purchase options in their price range. Where they stand out the most is in: The design. That it includes five pads is something very interesting if you don’t know very well how they are going to fit in your ears. With them, you can adapt the headphones so that they do not move, something especially interesting when walking, running or exercising. Your autonomy. The autonomy of the headphones (without charging case) reaches eight hours, so if you listen to music while you work, these are the ones that may interest you the most. Better water resistance. It’s not every day that we drop our headphones into a puddle or pool, … Read more

AI is very comfortable inventing everything it doesn’t know. Some researchers think they know how to stop him

by

The hallucinations have been the Achilles heel of AI since chatbots began to be part of our lives. Companies like OpenAI promised that hallucinations could be mitigated with adequate training processes, but years later both ChatGPT and its direct rivals They keep making up answers when they are not sure what to say. Shuhui Qu, a researcher at Stanford University, believes she has found a way to address the problem. A structural problem. Current language models have a factory defect: they respond with complete security even when they have no idea nor the necessary information. This has to do with how they progress when processing any answer, since LLMs have no problem completing the missing information, even if they are not being faithful to reality and are working with assumptions. First thing, recognize it. Shuhui Qu, a researcher at Stanford University, publishes an article in which she introduces what she calls Bidirectional Categorical Planning with Self-Consultation. An approach that starts from a simple idea, but uncomfortable for large technology companies: forcing the model to explicitly recognize what it does not know and not move forward until solving it. A more scientific method. The idea is not that the model think betterBut stop pretending you know everything. The approach of What starts from a basic premise: every time the model takes a step in its reasoning, it should ask itself if it really has the necessary information to do so. When an unknown condition appears, the model cannot continue. You are not allowed to fill the gap with an assumption, and you have to stop to resolve the uncertainty before moving forward. You can do this in two ways: Well asking a specific question to obtain the missing information Either by introducing some intermediate step (verification, additional consultation) that becomes part of the chain of reasoning. The method. The researchers, using external code, made models like GPT-4 They responded only when they had complete information. They did it with simple tasks, asking about cooking recipes and Wikihow guides. The key? They purposely withheld information to force him to stop. The conclusion of the research was that making preconditions explicit and verifying them before moving forward significantly reduces LLM errors when information is missing. Of course, along the way it is admitted that even this is not enough to make the hallucinations disappear completely. not so fast. Although the researcher’s idea sounds brilliant, it is quite unlikely to see it in the short and medium term. This way of processing breaks the natural flow of current LLMs, designed to return complete answers. To make such a system work, it is necessary to add an additional layer to the structure, some preconditions that force it to control the calls, interpret the responses themselves, classify them and self-block from asking questions if they do not have all the information. In other words, for the moment, AI will continue to score the triples to which we are already accustomed. Image | Xataka In Xataka | ChatGPT invents data and that is illegal in Europe.

Portugal and Spain have proposed that traveling between Lisbon and Madrid be as comfortable as in 1881. This is excellent news

by

31 years after the first promise, we will have a high-speed train from Madrid to Lisbon passing through Extremadura. We will have it, of course, if the plans are fulfilled. And four years later we will be able to travel the space that separates both capitals at high speed. 2030 and 2034. At least that’s what they’ve committed to. Portugal, Spain and the European Commission, who have reached an agreement to bring the connection between Lisbon and Madrid back to life in 2030 with a conventional train and in 2034 with a high-speed line that should make the journey in three hours. The calendar. To launch the line between the capitals, the project requires various phases and actions. Poceirão-Bombel section: new line that will begin construction in 2026 and should be completed in 2029. Évora-Caia section: this high-speed section should be ready in 2026. Lisbon-Évora section: the project study should be completed in 2027. Plasencia-Talayuela section: should be operational in 2028. Madrid-Lisbon at high speed: the new lines should allow travel between the Spanish capital and Portugal in three hours from 2034. In addition, the possibility of opening a Caia-Badajoz-Elvas high-speed line has been raised to reduce times and reach three hours if the planned times are not being met. Target: airlines. One of the great objectives that the European Union has with this new high-speed line is to reduce the number of flights between both cities. They point out in elDiario.es There are currently about 40 daily flights between Madrid and Lisbon. For years, European institutions have been working to reduce the volume of air traffic by improving rail connections. Spain either France These are some of the countries that want to implement policies to reduce them. A 600 kilometer railway line to travel in three hours is exactly the type of trip that can do a lot of damage to airlines if it works correctly. A good example is the Galician runner which, despite requiring more travel time, has made passengers turn their backs on the plane. And Galicia? If travelers who aspire to take their trains from Madrid are the big beneficiaries, Galicia seems to be the big loser. In recent yearsPortugal had insisted that its true intention was to create a high-speed line between Lisbon and Vigo with an intermediate stop in Porto. The project now takes a back seat, however, since they will have to focus efforts on high speed between capitals. In Atlantic They highlight that the European Union has already dedicated more than 250 million euros to promoting high speed in Portugal and more than 750 million euros to do the same in the connection between Extremadura and Madrid, so it seems logical that the first corridor to support this. A continental network. The project to link Lisbon and Madrid on a high-speed line is part of the European Atlantic Transport Corridor. The project plans to link Portugal, Spain, France, Germany and Ireland with intermodal connections that include roads, airports, ports… and railway lines. Regarding the latter, the connection with Madrid would allow connecting Barcelona with Lisbon in less than six hours. It would be a key stage for unite Lisbon with the rest of the European Union by train since, at the moment, the Portuguese capital is isolated by rail. In addition, it would allow rapid connection with other hot spots on the Spanish high-speed rail network, such as Valencia and Alicante or connections with Asturias and Cantabria. The exit to Vigo with the high-speed network that was already planned is the other possibility to reach the north of the Peninsula. The eternal promise. The connection between Lisbon and Madrid is a promise that has been going on for more than 20 years. In The World Order They highlight that the railway connection between both cities is worse today than in 1881 when a train line was opened between both cities for the first time. Between Berlin and Warsaw, they point out, there is a similar distance traveled by seven trains a day. Despite the first promises of having a cross-border AVE ready in 2010the line is still not operational. With the latest advances in the high-speed line, already present between Plasencia and Badajoz, the travel time between Lisbon and Madrid has been reduced to just over eight hours, as explained in The World Order but you have to take three different trains. In 2022, the same trip exceeded 11 hours, collected in The Country. At least 144 years ago, travelers only had to take a train and wait for it to drop them off in one of the two cities.

There was a day when getting on a plane was beautiful, comfortable and aspirational. Today most already hates it

by

Flying is fascinating. Or it was. Get on the plane, look for the seat and check with illusion that it has a window. A slight tingling when the route starts towards the track. The tremendous push against the seat at the time of accelerating. The incoherent feeling of ungravation when gaining height and we feel pressured against the bottom of the seat. The notice that we can take off our belt and yes, make sure that, mysteriously, we are flying. A formidable trip. I remember my first plane trip. With illusion, with nervousness. But everything changes when, due to the circumstances of life, the plane ceases to be something exceptional and becomes a more or less usual means of transport. Or when you arrive at the airport and check the huge tail with horror to pass a police control that, fortunately, It should be simplified very soon. Or when you discover that you measure more than 1.70 meters and enter the seat becomes an exercise in contortionism. Or when your look visualizes in the poster that the flight is delayed. Or when that little bridge getaway falls apart by an unforeseen cancellation. Or when you reach the destination and you have the keys and wallet at hand, but the suitcase has been lost along the way. Or when … A blow of reality. We have gone from seeing the plane as a luxury transport and associating it with an attractive and unique experience to pray because nothing happens if we have to take one. In 1951, Iberia flew for the first time to New York. On its website We can read how “a select chefs group prepared each meal, poured syrup on the cakes and prepared the trays that would then serve passengers aboard the Iberia airplanes.” There was no trace of huge queues before climbing the plane, from the distinction of passengers in four groups, “that suitcase does not enter” because it measures two and a half centimeters more than expected or charging significant amounts for choosing a seat. In the 50s in Iberia, “only the plane receives more attention than you.” They are not just sensations. It is not only a matter of sensations. Passengers begin to be really fed up with companies’s practices. In Financial Times They give as an example an American passenger who travels regularly with Southwest Airlines. In his five annual trips to the same destination he lived delays, cancellations for various reasons and even loss of the suitcase. It is not an isolated case. For the first time in more than a decade, the negative perception of flights exceeds the positive. In the United States, the fourth part of the 2022 flights were delayed or canceled and only in October the United States Department of Transportation registered 3,000 complaints of users, five times more than in 2019. Two hours. And 10,800 canceled flights. This was the result of a problem in the software of the Federal Aviation Administration of the United States that forced to leave on land all the air paths of the country for a couple of hours. 120 minutes that, as proven, wreaked havoc in the country with greater air traffic of the world. It is calculated which in 2019 traveled 925,500,000 passengers. With data from 2022, the United States is the country that has the most airports in the world. Its enormous distances and the absence of any type of commitment to the train as an alternative medium has caused that last year it will be counted until 16,890 airports. The second country is Brazil, with 4,093. The most recent data in Spain are from 2013, but then added only 150 facilities of this type. A funnel. One of the problems that indicate in the Financial Times article is the lack of workers. Coronavirus pandemia had cleaned, more or lessthe sky of airplanes. The increase in remote meetings caused many companies to ensure Bloomberg That the business trips had ended. But nothing is further from reality. Withdrawal restrictions, The number of trips has firmed again. While Airbus and Boeing thousands of millions are distributed in aircraft purchases, Pilots are missing. Many. In the United States alone, 8,000 new employees are necessary. By 2032 a world scarcity is expected of up to 32,000 pilots. And not just pilots. But pilot scarcity is not the only one that is causing delays, cancellations and generalized discomfort in travelers. In our country we know that traveling on vacation is synonymous with risk. The strikes of land workers, cabin staff and pilots have become generalized in summer and Christmas. The workers of the airlines generally denounce too much work at work for a lack of employees that crawls from the toughest months of the confinements by the COVID-19. It is estimated that those days said goodbye to 191,000 workers in airports and airlines.
