why technology has not yet solved this

by

Today tickets for Bad Bunny concerts went on sale. What should have been a happy day for fans It has become a nightmare. Many complained in networks of the error messages In the browser, the endless virtual linesthe Forced interruptions of the process or the worst, the messages of “exhausted entries” –or error– when They caressed success In that mission impossible. We are in 2025 and one would expect technology to have fixed this. And yet, he has not done so. What is happening? SALE BY ARRIVAL ORDER = Frustration. Traditional ticket sales systems work under an old and theoretically simple principle: the first one that arrives is the first to buy it. In computer science this is known as the FIFO (First In, First out) system for the implementation and management of queues, and has no major mystery. Or at least, not until you try to apply it to the sale of macroeventos tickets. Then, disaster. Too much demand. We have experienced it today when tickets for the concerts of the Bad Bunny world tour have come to sale. The demand has been colossal and has exceeded the offer, which has caused the service that managed the direct online sale has collapsed. Error messages were constant, and many users saw how they had to wait endless virtual lines And the process was interrupted at totally random times without them being able to do anything. When virtual tails reach figures of 15,000 users – for example, there are much more crazy– The system ceases to make sense. It is not useful or operational. He “Scalping“At the agenda. This stock market It is applied too In these scenarios and refers to the technique of buying tickets with bots and other systems that allow the limits imposed on entries for inputs for human users. Ticketmaster even created the Fan-To-Fan system As a controversial official controversy blessed by the system that Tickemaster, of course, takes its commission. It is estimated that Ticketmaster and Live Nation They control 70% of the business of the sale of tickets. And more problems with resale. There is an entire economy Around pages like Viago or Stubhub, which They buy mass tickets and then try to resell at greater price. The German Heavy Metal Rammstein Group went to court When demanding Viagogo, a company with which they have been fighting since 2018 for this issue. It happened with Renfe tickets. In April 2022 Renfe offered bird tickets to 15 euros. The promotion was striking, so I threw myself to the browser of my PC to try to take advantage of some of the options they gave me. After achieving access to virtual tail to buy one of those tickets, I met 166,321 people in front of me and an estimate of waiting time for an hour and a half. Half an hour later there were 144,115 people in front. The alternative was to use Renfe’s mobile app, but the process made it clear that these types of problems are constantly presented. The raffles work. In popular events such as Cycotourist march QH (Quebrantahuesos) The fans who want to sign up must first register as QH users, something that gives access to a raffle granted by the dorsals. It is a very reasonable solution to events with a demand greater than the supply. It is the method that also FIFA has used for years To sell tickets for football World Cup matches. The solution exists, only that it does not apply (much). It is a good example of a relatively simple system to solve the problems that have arisen with Ticketmaster on numerous occasions. The process would be as follows: Open a pre -registration to enter the raffle of entries. Leave it open for a prudential time of, for example, two weeks. There would be no careers for entering the pre -registration or being the first, because that would give exactly the same. Therefore, server overload risks are minimized. During that pre -registration the user must overcome Captcha challenges, double verification against email and storage of some credit card data. With this, the participation of bots in the process is greatly prevented. Payment of a symbolic commission for the pre -registration. Another very powerful measure to avoid the participation of bots. There should also be a limit for the number of records that can be made per person/mail/payment card. From there the draw is celebrated, which is granted X inputs from the number Y Registry. If there are 1000 tickets available and there are 10,000 pointed users, an example would be for the draw to come out number 6,713. The records from 6,713 to 7,712 would get their entrance. The winners could register in their account and buy the entry into a certain period. If not, that entry would be offered to the next one who could not obtain it after the draw, and so on. There would be no frustration, just bad luck. The draw or lottery process is much less frustrating. Of course there is the possibility that you do not get the entrance, but a system like this would avoid the great problems of the current direct sales mechanism that has proven not to be effective. But they do not decide the sustained. There is another big additional problem, and although there are solutions such as the proposal, who decide how entries are sold and buy are artists and promoters, who can go to alternative solutions. Concerts on demand. For example, Announce additional dates of concerts by surprise. It is a peculiar idea: it is thus possible to announce a limited number of concerts to measure demand, and from there adjust the offer keeping the number of events (if they can be replicated) programmed or changing it according to said demand.

Japan has just been put in the career of quantum computers. And he has done it with his own technology

by

China and the US are the countries that are dedicating more resources to the development of Quantum technologies. And also those who are reaching The most relevant achievements. However, no advanced country can afford to remain out of a technology with An indisputable rupturist potential in the medium term. In this field Japan is adopting a discreet position, but its contributions, although they are not as numerous as those of the other two countries that I have mentioned in this paragraph, are also very important. In 2023 a group of researchers from the Riken Center for Quantum Computing, in Japan, led by Professor Keisuke Fujii He devised a very advanced algorithm which dramatically reduces the computational complexity of some quantum procedures. His work was published in the scientific journal Physical Reviewand even today is the best available tool to efficiently reproduce the atomic level interactions that take place in some complex materials. The protocol designed by these Japanese scientists manages to deal with temporary evolution operators in a much more efficient way than the technique used so far, which is known as trotterization. In broad strokes these operators are numbers matrices that describe the very complex interactions that take place in quantum materials. In addition, the algorithm devised by Fujii and his colleagues is a hybrid solution that combines quantum and classic protocols, and has the ability to allow relatively simple quantum computers, such as those we have now, face very complicated problems. The Riken and Fujitsu center have made a quantum computer of 256 cubits Today, just a few hours ago, the Riken Center for Quantum Computing and Fujitsu They have announced which have developed in a joint project a superconductor quantum computer equipped with 256 cubits. A priori may not seem like a great achievement if we are in mind that IBM already has a condora superconductor quantum processor of 1,121 cubits, and also The Heron platform (5k) endowed with error mitigation. And the China Telecom Quantum Group (CTQG) and the Center for Excellence in Quantum Information and Quantum Physics of the Chinese Academy of Sciences have developed The Xiaohong quantum processor of 504 superconductor cubits. One of the most attractive assets of this quantum computer is that it allows efficient to scale the number of cubits However, the implementation of this Japanese machine deserves to be considered an undoubted success if we take into account that it uses technologies developed entirely in Japan. It does not use the hardware designed by IBM or Intel, which is what some research centers disseminated by Europe have done. One of the most attractive tricks of this Japanese quantum computer is that it allows Efficient scalar the cubits number No need to completely redesign all the architecture of the machine. In addition, the dilution cooling system used is, according to Fujitsu, more efficient than the solutions usually used in other quantum computers. This statement is credible because this 256 cubits machine works properly with the same cooling unit as the previous 64 -cubites quantum computer of the Riken center. It sounds very good. However, this is not all. The plan of the creators of this quantum machine is to have a computer of 1,000 cubits ready in 2026. If Japan get it, it will be placed in this field just one step from the US and China.

The US wants to build an unprecedented antimisile shield called “Golden Dome”. And Spacex has suitable technology

by

The idea of ​​an antimile shield that protects the United States from enemy attacks is not even original. Already in the era reagan, The country fantasized with an initiative nicknamed “Star Wars” That never saw the light. Now, the Trump administration wants to dust off the project with technology of the 21st century and a more intimidating name: “Golden Dome” (the golden dome). With Spacex technology. A technological consortium headed by Spacex, the Aerospace Company of Elon Musk, leads the race to develop part of the Golden Dome, Publish Reuters. Its proposal consists of a constellation of between 400 and more than a thousand satellites dedicated to detecting enemy missiles, following its trajectory and determining if they suppose a threat to the territory of the United States. Other separate fleet of about 200 satellites (armed with missiles or lasers) would be responsible for intercepting missiles; Although the group led by Spacex would not be, according to Reuters, involved in the offensive part of the system. Old acquaintances. In addition to Spacex, two other technology companies are part of the initiative: Palantir Technologies and Anduril Industries. Palantir is a government software co -founded by Alex Karp and Peter Thiel, old acquaintances of Musk. Anduril specializes in military drones and Autonomous Defense Technologies; Its most famous founder is Palmer Lukey, the creator of the Virtual Virtual Rift helmets. All of them, very aligned entrepreneurs and Donald Trump’s millionaire donors. If you liked, subscribe. The approach proposed by Spacex, Palantir and Anduril has an unorthodox turn for a defense contract for this magnitude: a subscription model. Instead buy and own satellite infrastructure, the Pentagon would pay a fee to access its services. This model, always according to reuters, could expedite the implementation by dodging the conventional procurement protocols of the Pentagon, but would also tie the government to a supplier and limit its control over the development and future prices of technology. After the publication of Reuters, which generated comments on possible conflicts of interest and worse things, Elon Musk responded in his X profile: “This is not true”, without giving more details. From Iron Dome to Golden Dome. The inspiration in the name seems clear: the Israeli iron dome. But the differences also appear in sight: Israel is a small country, with short -range threats. The United States is a continental country exposed to attacks from multiple vectors and with new threats, as the hypersonic missiles developed by Russia and Chinawhose erratic trajectories and extreme speed challenge current systems. Replicating the iron dome on an American scale is technical and economically unfeasible. Hence, the alternative that right now has more ballots is a solution based on the Starlink satellite constellation, which would cost between 6,000 and 10,000 million dollars. More politics than defense, for now. Although Spacex and its technological partners seem to be in the lead, traditional defense giants such as Lockheed Martin, Northrop Grumman, RTX or Boeing are not far behind and also bid on the part of the cake. The Pentagon has received proposals from more than 180 companies. The big question is whether Golden Dome will really be a defensive revolution against real threats (such as hypersonic weapons or orbital bombing systems) or If it’s just an electoral promise closer to the science fiction of Star Wars than to a pragmatic military strategy. If something has taught us the current administration is that nothing they are going to do tomorrow is predictable.

Intel’s future is linked to the success of a single chip manufacturing node: 18A technology

by

Intel is facing one of the most difficult stages Of all its history. And its story is not exactly brief. In fact, Gordon Moore and Robert Noyce founded this company more than half a century ago, in 1968. As we have explained in other articles, The future of factories and Intel chips packaging and validation centers is uncertain. However, it is possible that these facilities are finally incorporated into a joint company Managed by Intel, TSMCand, perhaps, by some other company of the integrated circuit industry. Anyway, the short -term competitiveness of this company is closely linked to the success of a single semiconductor manufacturing technology: 18A photolithography. Ben Sell, Vice President of Intel Technology Development, confirmed At the end of last September that the 18A node already has the maturity necessary to enter large -scale production in 2025. and also assured that it will benefit from the resources that have been reallocated since the 20A node. In the current scenario the 18A node will be the true protagonist. That is not the slightest doubt. More transistors. More performance. And less consumption This statement by Joseph Bonetti, main manager of Intel engineering programs, expresses very well The important thing that is the 18A node for this company: “Intel leaders, Board of Directors of Intel and Donald Trump administration, please do not sell or give the control of Intel Foundry to TSMC just when Intel is taking the technological front and starting to take off. It would be a terrible and demoralizing error.” Bonetti also maintains that Intel is not lagging for its competitors, and that the advances that their engineers are achieving in the field of chips production are very important. Bonetti does not expressly mention the 18A integration technology, but his statement is supported by it because right now is the asset that Intel has to compete with TSMC and Samsung in the market for the production of integrated circuits in a year in which 2 Nm photolithographies They will take off yes or yes. In the last months Intel has been revealing some of the characteristics of this integration technology, but just a few hours ago and as a prelude to the semiconductor conference ‘2025 Symposium on VLSI Technology and Circu has made public more interesting data. Powervia proposes to physically separate the feed lines and signal signal within each integrated circuit Lithography 18a is erected above all about two essential innovations: Ribbonfet Gate-Lall-Around (GAA) transistors and energy delivery technology Powervia. The purpose of this last improvement is to solve the limitations imposed by the introduction in the integrated circuit of smaller transistors, which are also together more. This scenario causes that within each chip the power lines and signal compete for the same resources, which triggers the appearance of bottlenecks that perceptibly limit the performance and energy efficiency of a CPU. The purpose of Powervia technology is precisely to solve this problem. And to achieve this, what proposes is to physically separate the power lines and signal signal. So far both lived in the same physical space, but From Intel 20A lithographythat It was commercially dismissed In September 2024, the distribution of transistors and food and signal will acquire the form of a sandwich. In this way the transistors will be housed in the center, while the feed lines will reside in a lower layer and those of signal in an upper layer. In any case, for us, the users, the most interesting thing is to know that Intel promises that their lithography 18a will deliver a 25% higher performance using the same voltage as the integration technology Intel 3, as well as a 36% lower energy consumption by using the same frequency and the same voltage. And by reducing this last parameter and moving from 1.1 volts to 0.75 volts, lithography 18a delivers a performance of 18% higher and a consumption of 38% lower. It sounds good, but we should not ignore that This information comes from Intel itself. Whether it is evident that we are interested in consumers that both Intel and TSMC or Samsung have the best state possible.

Tired of technology, they want houses as “dumb” as possible

by

Voice attendees, Like Alexa Or Google Assistant democratized household domotization, and lighting the lights with a voice command, controlling the washing machine remotely from the smartphone or making the purchase directly from the refrigerator was normalized. However, until a few years ago, The house domotized and automated were a privilege reserved only for The ultra -tricious tenants. That trend has taken a radical turn and, at present, the great fortunes seek just the opposite: “dumb” houses. Digital detoxification: a new form of luxury “We often hear our clients say that they don’t want a smartest house than them,”assured Holly Hunt, interior designer of luxury houses, Town & Country. It is not an isolated case. More and more ultra -ups want their homes to have the Less presence of technology possible. Far away from those years in which great Hollywood stars, such as Sofia Vergara, presumed to control all appliances from your home from your smartphone. Bill Gates brought his famous Xanadu 2.0 mansion to another level. As published Business InsiderGates’ guests received a device with which the house automatically detected its presence and adjusted the lighting of the stay, its temperature or the ambient music depending on their tastes. Today, the Ultrarricos prefer to get away from these houses Hyperconnected, “there was a time when attracting a high -level buyer meant having flat screens in almost all rooms, including external areas. However, in the current, excessively automated market, excess technology can be a great discouragement,” said Pacific Sotheby’s real estate agent, Gillian Flynn, in statements to The Hollywood Reporter. Experts in this type of high -end houses, such as India Alexandra, of the Real Estate The Mod House, They assured to Financial Times that “there are elements of the smart houses that some buyers find attractive because they provide comfort, control and efficiency. But, without a doubt, we have customers than prefer to live in houses with simpler and more traditional technology Linked to simple pleasures: take a long bath, turn on the heat, cook over low heat. The real estate expert stressed that “people lead a busy life, and a house is usually a refuge of technology that, otherwise, dominates life.” Thus, the ultra -ups no longer conceive their home as an automated place, but as a refuge of disconnection in getting away from screens and any type of technology. The hidden discomforts of smart houses One of the main conditions of this change in tendency is the constant advance of this technology, which does not always adopt the same standards and generate incompatibilities and programmed obsolescence That makes them old very badly. “The data show that approximately 57 % of housing owners with smart devices face compatibility problems, which makes the management of a connected home focus less on ease and more on problem solving. Intelligent technology is not always as simple as it is announced,” He pointed out George Carrillo, Executive Director of the Hispanic Construction Council in statements collected by the Real Estate Portal Realtor. Carrie Livingston, interior designer of Beverly Hills, commented on The Hollywood Reporter that their clients were tired of their Home automation systems valued at more than $ 100,000. “They did not find a single light switch throughout the house. The wife complained that every time she got up at night, her husband saw her illuminated path while she went from bed to the bathroom”, since the system automatically detected its movement and was turning on all the lights. Instead, “other times, it entered a dark room where the lights did not turn on how much stirred their arms,” ​​finally Livingston chose to eliminate the entire home system and Opt for a simple switch. Eyes everywhere The Domotized systems They also pose significant concerns in terms of security. According to Leonie Tanczer, an associated professor in International Security and Emerging Technologies to Financial Timesany device connected to the Internet It is likely to be hacked. In the same line they position themselves Cybersecurity companies such as Kaspersky, which alert about the safety vulnerabilities of connected devices and the risk that cybercriminals can access these cameras and take control of the entire home system. It is almost how to give them the house key. Another problem is the massive collection of data by these devices. All appliancesfrom the vacuum, the washing machine or the refrigerator, through the air conditioning or the TV, it is permanently connected to the Internet and collects data that reveal patterns of use and schedules, to give an example. In contrast, a “dumb” house eliminates these risks by completely dispensing with unnecessary digital connections. For many millionaires, the real luxury now lies in having a simple home where they can light the lights with a switch basic without worrying about invasive technological ecosystems.

The commercial war has trembling the technology industry. Samsung plays in another league

by

The recent one wave of tariffs imposed by the United States has unleashed a storm in the technological market. Apple, Google or Motorola have been indicated Directly because of its strong dependence on Trump, the main objective of Trump in this tariff war. But there is an actor who has barely appeared in the eye of the hurricane: Samsung. The silence around it is no accident, but a consequence of a competitive advantage forged for years. What has happened. Samsung left smartphones production in China in 2020. Since then, he diversified his supply chain in India, South Korea, Vietnam, Brazil and other countries. According to the consultant Counterpoint ResearchChina represents 80% of iPhone’s production, while for Samsung, it barely contributes mid -range with ODM designs premises. It is a very large contrast that has consequences. Why is it important. The commercial war is redrawing the hardware map. Whoever has the factory in the wrong country can see the price of their products triggered. In detail. Vietnam, a key country for Samsung (more than 60% of its mobiles are manufactured there), has received a 46% tariff waiting to see what happens after the extension. Even so, the Korean brand has maneuver margin. Its two factories in India – an unused capacity – can absorb part of the blow. On the other hand, South Korea could assume the production of high -end models if the situation requires it. Apple, on the other hand, does not have that agility: its diversification is still incipient. Between bambalins. Samsung He has been investing in Vietnam for more than a decade: 100,000 employees, 25% of the country’s total exporter and 220 million dollars only in R&D in 2024. This strategic alliance has become a double -edged sword. Now that Vietnam is in the tariff target, both parties negotiate against the United States to stop possible damage. But Samsung already had his plan B activated: transfer part of the production to India and Korea. In Xataka | Spain looked at Chinese cars as a salvation table.

The great technology built their empires in a connected world. Now that world is falling apart

by

The Trump tariffs They are not only an economic measure, but the visible manifestation of a phenomenon that goes much further: the potential fragmentation of the technological world in isolated and incompatible islands with each other. The technological map we knew so far is changing. The stock exchange that has evaporated almost 2 billion the value of technology – and climbing – in a few days hides points to Something more than short -term fears: The interconnected system in which the great technological ones built their empires are disintegrating. As Ben Evans says in your analysis of Stratechery“It is more difficult to overestimate the degree to which every aspect of modern life rests in global supply chains, so long and complex that no one can truly understand the effects of altering them.” The American Big Tech, whose success has been built on the premise of a world without digital bordersThey now have the nightmare of a planet that is, technologically, bursting. The American superisla dominated by Apple, Amazon, Google, Microsoft and Meta is surrounding increasingly turbulent waters. He will no longer be able to have cheap factories from China or Vietnam. The Chinese island, while, has a five years building its own ecosystems and standards. Huawei is a paradigmatic case. The European island, still in formation, focuses on regulation (GDPR, Dma, DSA) and tries to position themselves as “third way” with emphasis on values ​​about privacy and ethics, while maintaining critical strategic positions with manufacturers like ASML. We count it a few days ago: Huawei has not thrown five years building bridges, but cavando trenches. His Harmonyospresent in more than 1,000 million devices, does not seek to complement the global ecosystem, but replace it. Do not compete, build a parallel reality. West still thinks of market fees while Huawei builds an entire digital continent. The symptoms of this fragmentation are increasingly evident, and if nothing changes, they will go more: Nintendo delaying The early orders of the Switch 2. Vietnam negotiating the desperate to reduce tariffs. Companies drawing alternative supply chains in a hurry. They are only the superficial waves of the tsamot that is happening at the bottom of the digital ocean. We are facing The fracture of a technological model that we assumed universal. Where there were now integration there are digital walls. The economies of scale that allowed affordable smartphones and global services will give way to smaller, less efficient and possibly more expensive ecosystems. The end user will not only pay more for its devices but will have to choose which technology island belongs to. The European Union, aware of what is coming, no longer speaks only of response tariffs, but use his Anti-coercion instrument to “limit intellectual property rights” or “restrict the access of financial services to EU markets.” We talk about hardware, yes, but the war also extends to software, services and digital infrastructure. Europe could find its opportunity as a bridge between islands, taking advantage of its experience creating global standards (GSM, GDPR) that can be adopted beyond its borders. Our unique position, with relations with both the United States and China, could become integrators in a technologically fragmented world. And in this digital archipelago where Pangea was before Companies will have to decide which islands inhabiting and which ones to abandon. The divergent standards (with China we are already seeing it, They throw to their own HDMI), redundant supply chains and incompatible ecosystems will be the new normality. Innovation will no longer flow between continents, but will be confined in these technological islands, with its own rules, limitations and opportunities. Not that technological globalization is threatened, is that is being actively disassembled. The dream of a digital world without borders is coming to an end. Welcome to the technological archipelago.

At high-end assault with QD-OED and its best mini led technology

by

Sony’s bet for 2025 is something atypical. And this year he will not renew its entire range of televisions; It will complement the most advanced models that it launched in 2024, among which the Bravia 9, 8 and 7with three new devices. As we are about to verify, the Bravia 8 II It seeks to replace the model with an organic panel last year, but Bravia 5 and 3 expand a line of proposals that in 2025 will be more ambitious than in 2024. Although we are about to investigate on the televisions that this Japanese company will place in the stores during the next weeks, it is worth not overlooking that we have very interesting clues about what will propose in 2026. And what will arrive is, neither more nor less, than its first televisions equipped with a RGB LED matrix. We have talked about this technology quite depth in The article we publish in mid -March, and excites us. After all, it promises to make a very important leap forward as an image. Sony Bravia 8 II, Bravia 5 and Bravia 3: Technical Specifications Bravia 8 II Bravia 5 Bravia 3 panel QD-OED 4K UHD, 10 Bits, 120 Hz and 16: 9 LCD VA 4K UHD, 10 Bits, 120 Hz and 16: 9 LCD IPS 4K UHD, 10 Bits, 60 Hz and 16: 9 resolution 3,840 x 2,160 points 3,840 x 2,160 points 3,840 x 2,160 points available sizes 55 and 65 inches 55, 65, 75, 85 and 98 inches 43, 50, 55, 65, 75 and 85 inches Retroilumination No Mini LED Direct LED HDR Dolby Vision, HDR10 and HLG Dolby Vision, HDR10 and HLG Dolby Vision, HDR10 and HLG processor XR Processor XR Processor X1 Processor Operating system Google TV Google TV Google TV sound Dolby Atmos DTS: x Dolby Atmos DTS: x Dolby Atmos DTS: x Main characteristics Triluminos Max, XR contrast Booster 25, XR Clear Image, XR OLED MOTION, ENVIRY OPTIMIZATION PRO 6, GAME MENU 2, PS REMOTE PLAY AND ECO DASHBOARD 2 Backlight Master Drive, XR contrast Booster 10, XR Clear Image, XR Triluminos Pro and XR Motion Clarity Triluminos Pro y 4k X-Reality Pro price Not available Not available Not available These three televisions reinforce the range Sony proposed in 2024 I propose that we start investigating the most ambitious television characteristics of those who have just presented this brand: the model Bravia 8 II. His heart is An organic matrix QD-OED of the latest generation with a 10-bit color depth and a 120 Hz native soda frequency. Sony buys their organic QD-Oled panels from Samsung, but the image processing algorithms are executed by the engineers of the Japanese brand themselves. The new bravia 8 II delivers a bright peak level 25% higher than the bravia a95l We have weight reasons to anticipate that this TV will highlight for its image quality. My partner Antonio Vallejo has seen it in actionand he liked it a lot. And I have thoroughly analyzed their predecessors, the models Bravia A95K and A95Land Its image quality is fabulous. An interesting note: According to Sony the new Bravia 8 II delivers a pico level of brightness 25% higher than the Bravia A95L. And nothing less than 50% higher than Bravia 8 of 2024. It does not paint but nothing wrong. In fact, a priori is a very serious candidate for better 2025 TV. We will see what happens finally. Sony Bravia 8 II. We are now with the following TV on the ranks, the Bravia 5 model. Its heart is an LCD matrix goes from 10 bits capable of working at a 120 Hz soda frequency. Nothing especially remarkable so far. However, your best asset is your backlight system. And it is committed to a mini led diode scheme derived from that used by Sony in the models Bravia 9 and 7. The Bravia 5 model is committed to a mini led diode scheme derived from that used by Sony in the Bravia 9 and 7 On the other hand, like all the TVs of the Prémium, high and middle ranges of this brand, you can deal with content Dolby Vision, HDR10 and HLGbut not HDR10+. A pity. An interesting note: According to Sony the new Bravia 5 Multiply by five the independent local attenuation zones that it has The X90L model of 2023. Sony Bravia 5. Finally, Bravia 3 is the most modest of TVs by 2025 of Sony. He proposes an LCD IPS panel of 10 bit and 60 Hz, and does not have mini LED backlight; Bet on the much more humble direct LED scheme, so neither its contrast nor its level of detail in the shadow and high light regions will be as high as in the upper models. Of course, it maintains compatibility with content Dolby Vision, HDR10 and HLGas well as the ability to process audio Dolby Atmos and DTS: x. Sony Bravia 3. During the next weeks Sony will confirm both when these televisions will arrive at Spanish stores and their price. In Xataka | China is devouring the televisions market.

A victory for AI technology

by

In recent years, The use of copyright protected works To train artificial intelligence models has generated an intense legal and ethical debate. However, the limits of this practice remain diffuse. Now, a new movement in the courts has given a respite to the great technological ones, tilting the balance in their favor. Anthropic’s (partial) victory. This week, the company behind the chatbot Claude He got a favorable failure. As Reuters points outa Federal Judge of the United States dismissed the request of several musical editors, including Universal Music Group, who sought to provisionally block the use of protected copyright letters in the training of AI models. The origin of the case. In October 2023, Concord, Abkco Music & Records, Universal Music and several of his subsidiaries They took Anthropic to the courts. They accused her of using letters protected by copyright to train Claude, her chatbot of AI, who was able to generate answers with textual or almost textual fragments of her works. The plaintiffs argued that Anthropic had violated the copyright of at least 500 songs, although some specifically cited, such as Katy Perry’s ‘Roar’, ‘I Will Survive’ by Gloria Gaynor and ‘You Can’t Always Get What You Want’ of the Rolling Stones. They also stressed that the company did not have any license to use those letters. “There are already several aggregators of song lyrics and websites that fulfill this same function, but these sites have duly licensed the works protected by the copyright of the publishers to provide this service,” said the demand. Here presumably referred to web catalogs such as Genius or Musixmatch. The judge says ‘no’ to the motion. Judge Eumi Lee rejected the precautionary measure requested by the record records. He considered that they did not demonstrate irreparable damage or clearly evidenced how the use of protected letters to train Claude affected his reputation or the license market. In addition, he stressed that the petition was too wide. Claude no longer spits song lyrics. If you ask Claude today to recite the letter of ‘You Can’t Always Get What You Want’ of the Rolling Stones or ‘Roar’ of Katy Perry, the Anthropic chatbot will refuse for copyright reasons. Instead, it will offer some data related to the song, the album or the artist, but without reproducing it. This is because Anthropic reached an agreement with record records to apply filters that prevent their AI models, both current and future, to generate answers that violate copyright. That commitment was, in fact, one of the elements that the judge took into account by rejecting the precautionary measure requested by the editors. Everything is said. The judicial decision known this week does not end the case. The process continues its course, with both parties trying to achieve a victory. While the record records seek to protect the catalog of the artists they represent, Anthropic defends their training model supporting the legitimate use.

It is its grounding chips manufacturing technology

The American Blackrockthe largest investment company in the world, is very interested in a very little known emerging company dedicated to the manufacture of Quantum computers. According to ReutersPsychantum, which is what is the name of this Startuphe has raised At least 750 million dollars Through an ambitious financing round in which Blackrock seems to have brought the singing voice, but has not yet concluded. That this gigantic investment company is interested in the business of a company dedicated to quantum computers is not striking. The surprising thing is that your attention has fallen to a Startup Very little known. However, it is enough to investigate the psychantum strategy to intuit where Blackrock’s interest comes from. And this is not a small research company in quantum machines. Not much less. Psychantum already produces quantum chips thanks to its alliance with Globalfoundries There is a very obvious difference between Psychantum’s strategy and that of other large companies which are also investing in the development of quantum computers. Google and IBM have opted for superconductor cubits. Ionq and Honeywell, however, produce quantum machines with ion traps cubits. But Psychantum does not use any of these technologies. His philosophy It looks much more like that of Intel than to the companies that I just mentioned. It is possible to manufacture semiconductor cubits using materials very similar to those used to produce conventional chips Intel and Qutech, the Institute for Specialized Research in Quantum Computing that belongs to the Technical University of Delft, in the Netherlands, They demonstrated just a year ago that it is possible to manufacture semiconductor cubits through industrial procedures and using materials very similar to those used for produce conventional chipslike silicon oxide. Psychantum has also achieved it. In fact, he has forged an alliance with one of The main semiconductor manufacturers From the planet: the American firm Globalfoundries. And, apparently, together they are working on the development of the technology of Fotonic silicon to apply it to the production of integrated circuits endowed with quantum properties. This strategy has a very evident advantage against the production of cubits that require exotic materials: it allows to manufacture quantum processors with much more simplicity. In fact, It is feasible to produce them on a large scale through industrial procedure. This is precisely the Psychantum and Globalfoundries Plan. However, there is something else. On paper, semiconductor quantum chips have the ability to facilitate scaling in the number of cubits. And gathering more cubits in a single quantum processor is important not only to have more calculation capacity, but also to make possible the arrival of the first chips of this type equipped with the ability to amend their own mistakes. All this is what is at stake. There is no doubt that Blackrock knows very well where he gets.
