AMD’s problem is not that it does not make good gpus for ia. Is that it is not even close to Nvidia

by

AMD is doing things well, but even doing them still unable to compete with Nvidia. The company has just raised its renewed road map with promising models, but that is not a guarantee of anything to a NVIDIA that will not let its absolute leadership position escape. The problem for AMD is not to be, but get others to take note. IDC consultancy data indicate that Nvidia dominates the AI ​​chips market with 85.2% market dick, for 14.3% AMD. Other analysts like Jon Pedie Research go beyond and According to your data The NVIDIA quota in this segment is 92%. AMD instinct mi350 are just the beginning. The GPUS for IA, which AMD calls “accelerators”, follow its evolution. During the event they presented their family or Instinct Mi350 series with two variants, MI350X and MI355X. According to the manufacturer, these chips are four times higher in general performance with respect to the previous generation, but are up to 35 times more powerful in the field of inference AI (that is, in the practical use of models such as Chatgpt, which “infers” “their responses from our prompts). They have 288 GB of HBM3E memory and a memory bandwidth of 8 TB/s. Its yield is 18.45 pflops in FP4 precision and 9.2 pflops in precision FP8. Instinct Mi400 in 2026. Next year the new family of AMD’s accelerators will arrive. It’s about future MI400 instinctwhich will arrive with up to 432 GB of HBM4 memory, 19.6 TB/s of bandwidth of that memory, and a performance of 40 pflops in precision FP4 and 20 Pflops in precision FP8. These monsters will be sold in future racks with infrastructure “Helios“, that You can house Up to 72 Mi400 with up to 260 TB/s total bandwidth thanks to its interconnection technology, Ultra Accelerator Link. EPYC VENICE. AMD not only talked about GPUS: it also has its future processors for servers in data centers in full development. The Epyc Venice will arrive in 2026 and will be based on Zen 6 architecture. Among the variants, an especially spectacular with 256 cores that will offer up to 70% more performance compared to the previous generation. These processors will be built with future MI400 instinct. They are expected to be manufactured with the N2P (2 Nm) node of TSMC. Helios against Oberon. The aforementioned Rack Helios will compete with not already with the current Nvidia AI server, the GB200 NVL72 which connects 36 CPUS Grace and 72 Gpus Blackwell. He is destined to compete with his successor, which has Oberon’s code name and will use IA B300 GPUS with Vera Rubin architecture. The yields and benefits of these future racks are absolutely dizzy, and for example their Precision Power FP8 is 1.4 Exaflops. The same in some things, better in others. AMD promises to match NVIDIA in several sections, but also ensures that it will exceed it remarkably (50% more) in memory quantity and width, something crucial for training and inference AI. Be careful, because at the end of 2027 NVIDIA prepares the Rubin Ultra architecture, which promises racks with up to 5 Exaflops in FP8 precision, three times more than Helios or Oberon. In 2027 we will have another “summer”. The AMD roadmap goes further, and they have already prepared the development of their new generation of chips for summer Epyc servers, which will replace the Epyc Venice. These CPUS will be paired with the future MI500X instinct, and it is expected – although it is not safe – that both types of chip take advantage of the one already announced TSMC A16 node (1.6 Nm), which will begin to be used at the end of 2026. There are no specifications for these developments, surely because they will depend on the manufacturing node that AMD ends up using to produce them. Frantic race. All these ads show that AMD does not want to be left behind in that race to place their solutions in data centers worldwide. The Crusoe company, which is dedicated to the construction of large AI data centers, advertisement A few days ago I would spend 400 million dollars in AMD’s chips, and even Sam Altman, CEO of OpenAi, made a surprise appearance During the inaugural talk of the Lisa Su, CEO of AMD event. Altman said they will also use AMD chips in the data centers they use, and highlighted that the new AMD ia gpus “will be somewhat amazing.” AMD presumes to be more efficient (and cheap). AMD’s message was clear during the event: its MI355 offer much more efficiency and are cheaper than NVIDIA B200 and GB200 with comparable yields. The sales prices of those GPUS are not known, but we do know that at the beginning of 2024 the MI300x of AMD They cost a maximum of $ 15,000 for the more than $ 40,000 that cost The NVIDIA H100. The biggest challenge is still CUDA. The benefits of AMD AI chips are not in fact the problem of this company. Detailed studies revealed months ago that MI300X are clearly higher than NVIDIA H100 and H200 on performance and power. However, Nvidia has a Cudathe de facto standard in the industry for services of services and applications of AI. Using AMD native software is feasible, yes, but software experience, They assured in SEMIANALYSIS“Software is full of errors that make training (AI models) with AMD it is impossible.” AMD’s hope is Rocm. In that AMD event also presented Rocm 7, the latest version from your own Open Source programming platform for your GPUS. In AMD they indicated that this version is 3.5 times more powerful than Rocm 6, and even claim that it is 30% more powerful than CUDA in the B200 when serving the model Deepseek R1. Even so, they indicate In another report of semi -health, it is still lower in some sections. Getting that component allows developers to take advantage of all the potential of AMD’s chips is precisely key to the future of those efforts. Even … Read more

The collision between the Milky Way and Andromeda has begun. The good news is that it will not be necessary to fill a friendly part

by

We know that the gaseous extremes of our galaxy and our neighboring galaxy are being touched, but there is no worry. Although astronomers safely a fusion of the Milky Way with Andromeda, they now question it. Short. A astropathic team has just published the biggest portrait of Andromeda, our neighboring galaxy, thanks to the Hubble observations. The image covers 600 fields of vision of the space telescope and shows the entire Andromeda album, which now has more than 200 million censored stars (two orders of magnitude more than those known so far). Although Andromeda’s gas bubbles are already touching the Milky Way, the new data 50% reduce probability that galaxies collide. Gaseous collision. In 2020, the Amiga program mapped 43 quasars in the background, confirming that Andromeda’s plasma halo, a hot gas bubble that measures two million light years, It flasses with the gas halo of the Milky Way. In a way, the gaseous bodies of both galaxies are already being touched, although in a faint way that neither the stars nor the planets notice it, so it will not be necessary to fill a friendly part of an accident. Maybe it never happens. The New 2.5 Gigapixel image of AndromedaResult of the PHAT and PHASET observation campaigns of the Hubble, it is not only another feat of the space telescope. It has served to question the theory that Andromeda and the Milky Way will end up merging. The classical narrative said that both spiral galaxies They would melt in about 4.5 billion yearsforming a giant elliptical. The new model, published in Nature Astronomyreduce the probability of fusion to 50% after 100,000 simulations. How they know. Astronomers at the University of Washington integrated the new Hubble data and the Gaia space telescope of the European space agency in their simulations. In addition to Andromeda and the Milky Way, they included the updated mass of the Great Cloud of Magallanes and m33. The key is in these two satellite galaxies. M33 Andromeda and the probability of shock increases. But the great cloud of Magallanes, with an almost perpendicular orbit, pushes the Milky Way out of the plane and reduces the meeting rate. In the most extreme stage, the front blow is still possible; In the softest, both galaxies will limit themselves to orbly during eons. What we were. The contact of the Andromeda plasma halos and the Milky Way suggests that the exchange of gas between both galaxies has already begun, but that does not guarantee a galactic fusion: the discs are still 2.5 million light years. In order for the merger to occur, the friction of the hals would have to stop the galaxies until the separation is 300,000 light years. Half of the trajectories simulated by the new study discard it.

Apple has chosen to be the Microsoft of the 90s. They are good and bad news at the same time

by

They are late for the AI ​​revolution, but compensate Apple Intelligence in Invisible and indispensable infrastructure. There was a particularly revealing moment in the Keynote of the WWDC 2025: While the technological world lives its greatest revolution since the arrival of the Internet, Apple dedicated fifty -two seconds to talk about Apple Intelligence. The rest of the time spent talking about things such as the new telephone app or personalized funds for Imessage. Then they spent more time talking about Foundation Models and integrations, but the most explicit Apple Intelligence for the user was relegated. It is as if in 1996, in the middle of the Internet explosion, Microsoft had focused its Keynote on improving the Windows Paint and lonely. The analogy is not accidental because Apple is repeating part of the Microsoft strategy of the nineties: Arrive late to a technological revolution and compensate with deep integration what they lack in pure innovation. When the Internet began to change the world, Microsoft did not create the best browser, protocols or web servers. But Internet integrated so deeply in Windows that it became impossible to avoid. They did not lead that technology, but made it indispensable within their territory. Apple is executing the same pattern, although with a nuance of the size of Alicante: they have developed their own models for Apple Intelligence. And now they translate into new specific functions: Machine translation. Calling spam. Personalized sports motivation. Your Foundation Models gives developers direct access to that local intelligence. But when you need real conversation, complex reasoning, advanced creativity … there they turn to Chatgpt. The Current Siri Without Openai remains the usual: appropriate for basic commands, but it is lost as soon as you leave the script. For the conversational and productive jump that defines this era, Apple depends on others. Your strategy is intelligent: Controlling the everyday and routine where integration matters more than gross power. Subcontracting the advanced where they still cannot compete. They do not sell as a product, but make it a kind of digital oxygen. You breathe it without realizing it. Google, Openai or Anthropic compete to create the best chatbot and surround it with functions that underpin it. Apple opts to integrate intelligence in each basic interaction of its devices. You do not need to open chatgpt to translate a message, it simply occurs. You don’t look for an app to filter spam calls, your iPhone takes care of that. It is the difference between selling electricity and selling appliances that work with electricity. Amazon executed a similar strategy when he arrived late to the conversational. They cannot compete with chatgpt in headlines, but they are making Its AI is the easiest option for companies that already live in AWS. They do not define the future of AI, but they do domesticate it within the infrastructure they live. The problem is that This defensive strategy comes with expiration date. The Microsoft of the nineties had serious problems when it lost the train that took him from the PC to the mobile. His domain by integration evaporated as soon as the dominant platform changed. Apple did manage to reinvent himself with the iPhone and with the Wearablebut AI is moving much faster than previous transitions. The PC Revolution → Mobile took a decade, the AI ​​revolution is happening in less than a five years. Apple Silicon took another decade of internal development to Apple. To lead the conversational that defines this era they would need a similar investment in research. The question is if they are ten years old. The window closes every time Openai presents a more capable modelevery time Google Integra Gemini more deeply in Androidevery moment they lose defining what the conversational means for the end user. Apple, for the moment, is playing the perfect letter for the short term. Its integration is superior, its most credible privacy, its most polished experience. They control infrastructure and experience, but they subcontract the intelligence that really differentiates this era from all the above. It’s like perfectly controlling iPhone’s hardware but depending on Google for apps that people really want to use. And this is especially paradoxical coming from Apple, A company that has invested decades and billions in controlling fundamental technologies: They developed their own operating systems so as not to depend on Microsoft or Google. They created Apple Silicon not to depend on the cycles and limitations of Intel. They are developing their own modems so as not to depend on Qualcomm and The C1 already debuted with the iPhone 16E. Apple understands better than anyone who controls base technologies controls the future. But with the generative AI they have chosen to be the best integrators instead of competing frontally for creating the best models in the world. It is a conscious resignation to that ‘big’ competition that defines the technological ages. “ Apple Intelligence works, and it works better the less explicit it is. It shines in the subtle, in the rear layer. But the history of technology teaches us that defensive strategies have limits. Microsoft dominated the nineties with superior integration, until a platform came where that integration no longer matters. The question is not whether Apple can continue to be the best integrator of others. The question is yes, when the redefine completely how we interact with technology, it will be enough to have been the perfect host of a revolution that others wrote.

China is stopping money and is starting to charge it. They are not good news for Spain

by

The golden age of Chinese financing is over. Beijing no longer gives money to build ports and railroads, now it is demanding payment of what it lent at the time. Why is it important. China has lent more than 800,000 million dollars to 150 countries since 2013 With its initiative of the ‘Silk route‘. Today, 60% of that portfolio is in the hands of technical bankruptcy or on the edge of the financial collapse. The facts. The money that countries must return to China every year already exceed the “new” money that China lends. It is the end of the expansive model of the last decade: the country is going from being a generous lender to becoming a relentless creditor. The strategy. China has divided its debtors into two categories, and each group applies a radically different treatment: Large countries with huge debts (80% of the portfolio): They receive bailouts, bridge loans and special facilities. Pakistan, Sri Lanka, Venezuela, Argentina, Angola … Small countries with minor debts (Remaining 20%): Only payment extensions. Zero money new. Zambia, Ghana, Mongolia, Tayikistan, Republic of Congo … Of course, the treatment that the first group receives has nothing to do with generosity but with self -preservation. China is rescuing those who, to break, could make their state banks sink. The rest are abandoned to their fate. The context. The crisis began soon. Specifically in 2015, two years after starting this strategy, when the prices of some raw materials collapsed. Covid accelerated the problems, as well as the war in Ukraine. The rise in interest rates at a global level It was the lace. The money trail. China is replicating the Western Banks Manual of the 1980s and nineties, when Wall Street and the City massively lent petrodollars after the oil crises of the seventies. When the eighties debt crisis arrived, they went from financing development to demand structural adjustment programs. The same banks that had pushed indebtedness became the toughest creditors. China is in that transition: of “Strategic Development Partner” to creditor which prioritizes their banking balances on the stability of debtor countries. It is the market, friend. Deepen. For Spain, the change has three impact vectors: The big construction and Spanish engineering (ACS, Actiona, Sacyr) lose access to megaprojects financed by Chinese banks, especially in Infrastructure in Africa and Asia. Direct Chinese investment in Spain will be more selective: less strategic purchases and more demand for immediate profitability in sectors such as energy and technology. Financial instability in African and Latin American countries where Spanish companies (Telefónica, Iberdrola, Repsol) operate increases political and exchange risk, complicating its operations in markets that depended on Chinese financial oxygen. In summary. China has completed its emerging power metamorphosis to established power, and its financial policy reflects it. The Silk Route was the last great expansive project of a country that sought global influence buying loyalty with cheap money. Now that it has that influence, it acts like any mature creditor: charging. It is the end of an era and the beginning of a more predictable global financial order, but also more ruthless.

Apple believed to have an excellent plan to deploy its AI in China. He is going as good as everything else in China

by

Souring records are precisely that, bittersweet. In Apple they know well: in the first quarter of 2025 124.3 billion dollars entered, but that colossal figure is fogged by a worrying fact: In China things are going wrong. The company is no longer what it was there, and has lost 9% market share in a year. In Cupertino, yes, they had a plan to relive sales: offer Apple Intelligence, and also do it with a category Chinese partner. Specifically, with Alibaba, which seemed the ideal option for its influence on the Chinese market and also for having a chatbot Especially advanced as Qwen2,5-Max. The plan was not bad, especially considering the worrying situation that Apple lives with its disastrous deployment of AI functions. Apple Intelligence is still far behind its competitors, and Siri’s scandalous non -zacing has revealed Internal rivalries, indecision and leadership problems In the company. But with Alibaba everything seemed good. The actions of the Chinese company rose like the foam after the rumors and everything seemed to go stern. It is not like that, and the deployment of Apple Intelligence in China with its new partner is delaying because of Chinese regulators. Apple and Alibaba have collaborated in the development of various AI products to be able to implement them, and have asked the authorities to regulate this sector to approve. But the administration of the cyberspace of China (CAC), main responsible for giving that blessing, has not done so. These requests are currently blocked According to sources close to the process cited in FTand reason is not technical, but political. The uncertainty about the situation between China and the United States and that commercial war that they maintain – and that affects the entire world – is causing that blockade, according to these sources. The situation for Apple is complicated On the one hand, he tries to deal with a US president whoUaiere forcing What Apple manufactures the iPhone that sells in that country locally. The idea is so expensive for Apple that will continue Going to account sEguir man by manufacturing them in India To avoid Chinese tariffs. On the other, it has been left behind for sale of iPhone in China, where Xiaomi, HuaweiOppo and alive have already advanced it. All of them have the government’s support and are tightening too In the supply of AI functions, but Apple Intelligence is still not a competitive proposal. Precisely the CAC approval process includes those AI tests. The AI ​​models developers themselves in China cannot market them or publish them unless they receive the approval of the government, which wants AI models “Very socialist“These restrictions should have favored Apple, especially after the alliance with Alibaba, but the tensions with the US after the absurd rise in tariffs -now in pause– They have made the situation unusual. The situation is so complex that Apple faces double suspicions. First, the final approval of the agreement between Apple and Alibaba to implement those functions of AI in the iPhone in China must be validated by the Chinese State Council. And second, the Bureau of Industry and Security of the US Department of Commerce has shown according to FT its reservations with that agreement, although they do not have legal means to prevent it. The situation is complicated, and that blockade of validation only becomes more. And meanwhile, Apple and Huawei grows. From the beginning of 2023 until now, Apple’s share in mobiles in China was 70%, and is now 47%. Huawei’s? It was 13% and is now 35%.

Japan has been a test laboratory for years to encourage birth. And he doesn’t have good news for the world

by

Neither The aid. Nor the facilities for access education. Nor the improvement of working conditions. Not even attempts for Exercise “Casélro” and create new couples. The repeated attempts of the Japanese authorities to reactivate their Merm Birth They are clicking on bone and have not prevented the country from closing 2024 with a bleak demographic panorama. Its fertility rate is minimal, births have fallen below the barrier of 700,000 per year and the number of deaths far exceeds the babies. Thus, the country faces a question that They have been Considering analysts: what can a government really do to encourage birth? Can you avoid collapse by looking for everything to the measures of Economic cut? Birth. 2024 has not been a good year for Japanese demography. His Ministry of Health, Labor and Social Welfare has just confirmed it in A balance Desorator and confirms that, despite all its efforts, the country has not yet found the appropriate key to avoid collapse. Among all their data there are two special worrying and that give an idea of ​​the descending drift that is drawing its birth: the fertility rate and births. Last year the global fertility rate (the number of children that a woman would have if she lived until the end of her fertile life) It stood at 1.15. A bad result twice. Not only is it 0.05 points less than in 2023, but it leaves that indicator in historical minimums. This is the lowest recorded data From at least 1947which further away to Japan from the one known as Replacement ratethe necessary number of children (2,1) to maintain a stable population without taking into account immigration. In Tokyo that indicator It does not arrive Even 1. A fact: 686,000 babies (and down). The other devastating fact for Japanese demography is that of the number of births. In 2024 the Japanese Ministry of Health accounted for 686,000, 5.7% less that in 2023. It is the first time in addition (at least since 1899, when the official registration began) that the number of annual lighting was below the 700,000 barrier. The Japanese authorities already had the birth would cross that psychological red line, but they expected it to do so within several years. The forecasts of the National Institute for Research of the Population contemplated that 2024 be closed with some 755,000 new babies And that the births would not fall below the barrier of 690,000 to a decade and a half, in 2039. The predictions were pessimistic, but they have fallen short: that threshold crossed 15 years earlier than expected. ASAHI remember In fact, the 2024 data has coincided with the worst projection drawn by the body. Losing population. The data of the Ministry of Health show only the photograph of the native population resident in the country, excluding both foreigners born in Japan and Japanese born outside their borders; but reveals a serious problem in the demographic engine of the nation. The reason is simple: more Japanese die than they are born. The 686,061 babies scored in 2024 remain away from the 1.6 million of deaths (1.9% more than in 2023). That translates into a negative balance of 919,237 people, around 70,000 people more than the previous year. To understand what this data supposes in practice, Nikei Slide that equivalent more or less to lose all Kagawa in a matter of 12 years. That hole also adds to those that Japan has been suffering over the last years. After all, it carries almost two decades supporting more death than births, which is reflected in Evolution of its total population. A small ray of light: marriages. Among all these negative data the balance of the Ministry of Health leaves one in positive: the number of marriages. The organism registered 486,0632.2% more than in 2023. They remain at low levels and below half a million, but leave the first increase in two years. And that is very relevant to birth. Although in Spain and other EU countries it is increasingly common That couples have babies without going through the altar, in Japanese society births outside marriage or de facto couples are still rare: Nikei remember which in 2023 represented 2.5% of the total. A matter of state. Japan is not the only nation that dealt with birth problems. Something similar happens to South and China. And like them the Japanese authorities have deployed A wide fan of measures to try to reverse the trend that include from children’s subsidies or measures that facilitate education for initiatives to Promote creation of new couples. “Focusing children related to children and parenting is something that cannot expect or postpone,” warned two years ago! Fumio KishidaJapan’s Prime Minister until last October. The problem worries enough to Tokyo for its executive It would be proposed Raise public aid by son to levels similar to those of Sweden and thus avoid that the nation lost “its ability to operate as a society.” That same year the government announced An ambitious plan to encourage birth to deploying a millmillionaire investment. Can you solve with money? That is the question that leaves the last demographic balance of Japan and that have been raising analysts for a long time, both inside and outside the nation. Are economic -economic policies enough to encourage birth? There are those who indicate that at least these strategies must be accompanied by deeper changes and even A rethinking of certain ideas and attitudes rooted in their culture. In 2023 Tomas Sobotka, deputy director of the Institute of Demography of Vienna, He pointed out some keys that feed the demographic crisis and that go beyond subsidies or married policies. The list includes the delay in the age of motherhood, cultural and social changes that lead to young people choose to remain single and without children, a change in the homes themselves, the greatest presence of women in the labor market and a philosophy of life that prioritizes professional ambitions and leaves little time available for parenting. … Read more

If you had always dreamed of having your own tunnelador or an industrial crane, good news: they are in Aliexpress

by

If there is an absolutely reference country in the field of tunneladoras, that is China. The funny thing is that these industrial machines can be found and buy very easily: it is enough to take a walk through Aliexpress or Alibaba to see them already prepared the sale along with other machines in the field of construction such as Cranes for containers. Second -hand tunneladoras. As Point out The specialized medium JR Urbane Network in X, it is possible to find second -hand tunneladoras in Alibaba or Aliexpress. It is enough to search for its conventional name (Tunnel Boring Machines, TBM) so that among the results a good number of them appear. As this media explained, China Recycle these tunneladoras and reuse them in different underground projects. Prices. The image machine, the CTE6250, is a medium -sized TBM with a weight of 500 tons and a six meter shield diameter. This model is Available in Alibaba for $ 688,000. A “micro machine” of “underground elevation” without excavation and with a six -meter shield diameter is $ 288,000. If we want it bigger, 9.1 meters in diameter, we will have to pay $ 748,000although taking it home will not be easy: it weighs 1,150 tons. Its manufacturer, the company Gansu Technology Equipment CO, has various models available in Alibaba. How TBM operates. These machines go beyond being a gigantic and powerful drill: in addition to the rotating cutting device, the tunnelador is equipped with a equipment that allows it to collect the rubble that is generated as the galleries open and stabilizes its structure. In addition, models that excavate underwater tunnel Hermetic mixture special and prefabricated and intertwined concrete blocks. Giant tunneladoras. In July 2023 we already talked about the Tunnel Mixshield S-880 “Qin Liangyu”. It was designed for the underwater tunnel project Tuen Mun-Chek Lap Kok in Hong Kong, and served to dig a stretch of about 5 km under the sea. It measures 120 meters long, weighs 4,850 tons and most importantly: the diameter of its shield is 17.63 meters. She is the largest tunnelador in the world. Although the tunnelador was manufactured in Germany by the company Herrenknecht Agthe assembly and operation was carried out in one of the factories of this company in China. Excavates about 30 meters of tunnel a day and is officially The largest TBM in the world According to the Guinness book of records. China winning Germany. We already have a candidate to overcome it: The Jianghaideveloped by China Railway Construction Heavy Industry (CRCHI) and the so -called China Railway 14th Bureau Group. This machine weighs about 5,000 tons, measures 145 meters long and has a shield diameter of 16.64 meters. The goal is to use it to build a tunnel that cross the Yangtsé River in the Chinese province of Jiangsu, between Nantong and Suzhou. And many industrial machines. A TBMS search in Aliexpress Not only offers offers for this type of machines, but for many other of this segment – perforas, industrial milling machines – and even cranes for maritime transport containers. In Amazon it is possible to find excavators/milling machines of “small” dimensions (1.8 m in diameter) for about $ 25,000, but the Chinese machines are at another level. Musk’s are small. It is not the only one in its class. Much more recently We met the Shanhe tunnelador163 meters long, 5,200 tons of weight and 17.5 meters in shield diameter. This machine is used to build the world’s largest diameter submarine tunnel. The company The Boring Company created by Elon Musk uses much smaller, almost “portable” tunneladoras: the PRUFROCKfor example, it has a shield diameter of 3.6 meters, although that allows it to dig much faster: approximately 1.6 kilometers per month. China, referent. In China Daily They point How 7 out of 10 tunneladoras sold in the world are Chinese, and within the country 95% of these machines are also of national manufacture. As in other industries, there is a strong commitment to self -sufficiency and technological domain in key areas like this. Although the largest are Herrenknecht, companies such as China Railway Engineering Equipment Group (CREG) have been one of the market leaders in manufacturing and sale of tunneladoras for years. In Xataka | England and Ireland wanted to create the longest tunnel in the world. A “stupid” and “advanced in your time”

Ten years ago, we were happy with microSD cards on mobile phones. The manufacturers have killed them for a good reason

by

Far was that time when buying a MicroSD card It was practically an essential for our mobile phone. The mobiles from ten years ago They came with a scarce internal memory (8, 16 GB), insufficient for devices that, despite their limitations at the hardware level, recorded Full HD video and had an ecosystem rich in applications. Today, it is increasingly difficult to find devices compatible with this memory expansion. And, yes, this is good news. The golden age of the microSD. There was a time in using an SD was the best possible option on an Android mobile. In fact, the operating system itself allowed to move some of the apps to external memories, releasing the local memory of this load. In 2010, Android 2.2 Froyo He had this option as a native from the adjustments, something that remained immovable until years later. The key was that Android was a much more insecure system than is now. In fact, with Android 6.0 It was possible to expand system storage using microSD cards. The party is over. There are two milestones that mark the progressive disappearance of MicroSD cards on Android. The first is the Popularization of Unibody mobiles: The end of the removable housings. The extra groove to incorporate the SD next to the SIM (or double SIM) hinders stagnant designs, somewhat incompatible with the Current IP protocols They protect the water and dust device. The second reason is imposed by Google with Android, and that is that the operating system was progressively restricting the permissions until they prevent them from moving apps to the SD, limiting it only to the passage of files. Reading speed. As internal memory modules have been improving progressively, reading and writing speed has shot in recent years. A UHS-1 micro SD around 200 MB/s reading speed (speeds that are never reached). EMMC’s most modern standards (slower technology in internal memories, only used in low range) can double this figure. If we talk about UFS memories, standards such as UFS 2.2 around real writing speeds close to GB, something that doubles with UFS 3.1 and almost quadruplica with UFS 4.0. Next to nothing. The size of the apps has increased considerably in recent years, as well as their requirements, and moving them from an SD is not too realistic. The focus on security. By default, the memory of any commercialized Android mobile comes encrypted, something that protects the local data of the device. SD memories do not come with this protection layer, nor do they meet the requirements to do so. Android is an increasingly sure system And, according to the latest data, it is exposed to 90% less malware than in 2016 thanks to the Play Protect scanguaranteed windows of security patches, Automatic reset and constant purge of fraudulent applications in Play Storeamong others. The microSD today. Although relegated in general terms to low -cost mobiles, The MicroSD continues to give a dummy In 2025. If your mobile has support for them, you can continue moving simple apps such as Telegram or Instagram (giants such as WhatsApp do not allow it), and even some games allow you to send part of your reading data to the SD. The same goes for multimedia: nothing prevents us from saving and reproducing content from a microSD card externally. The limitation of speed and stability (if you use a low quality microSD) will be present, but the function has not died at all. A necessary evil. Smartphones manufacturers and Google itself have been closing the door to microSD cards. It is a evil necessary to improve the stability of the system, to make Android a safer platform and continue allowing the apps to grow (in size and requirements) to the frantic rhythm to which hardware evolves.

The blackouts of Spain and London are a good example

by

A couple of months ago, a fire in a substation left without electricity To a part of London and temporarily paralyzed Heathrow airport. A month later, the Iberian Peninsula suffered a mass blackout. Two incidents separated by kilometers, but united by the same question: how fragile is the electricity grid? More than is thought. The energy expert, Simon Gallagher has addressed this topiccategorically discarding the theories of sabotage or systematic negligence relying on data provided by UK Power Networks (UKPN) and Scottish and Southern Electricity Networks (SSEN). According to Gallagher, the failures in transformers are not only common, but also expected in such a complex system. UKPN, for example, reported about 400 failures of transformers a year, although only about 30 affect more than 500 customers. Although these failures can affect from small transformers in rural posts to large urban units, the figure has remained stable. Is it stable? Simon Gallagher is based on The 2024 UKPN annual reportwhere the average customer was without electricity just 29 minutes throughout the year, which is equivalent to an availability of the service of 99,994%. This level of reliability is the result of years of investment and continuous improvement. Since 2010/11, UKPN has reduced its lost minutes by client by 55% and interruptions by 43%. A very controlled system. The British electrical system is designed with a high degree of resilience. When a component fails, there are alternative routes through which electricity can be redirected, avoiding interruptions. This capacity is complemented with automatic failure detection technologies, which isolate the breakdowns in seconds and, in many cases, restore the supply without human intervention, Thanks to self -refrarable networks or Self-Healing Grids. To this is added Predictive maintenancewhich allows to replace or repair components before they fail, and a hierarchy of equipment that minimizes the impact of the failures: a failure on a low -load transformer affects little, while high voltage those receive greater protection. This robust architecture It is backed by the Riio-Ed2 regulatory frameworkpromoted by Ofgem, which forces distributors to maintain strict standards of reliability and response. So the blackout of Spain? While the British electrical system relies on a hierarchical network with high redundancy, predictive maintenance and self -repair technologies, the recent blackout in the Iberian Peninsula has shown that the resilience of the Spanish system needs to evolve in another direction. The more you know about the incident, less weight has the initial explanation focused on the lack of inertia by renewables. On the other hand, the absence of distributed storage, The lack of micro -redes capable of temporarily isolation of the main system and low capacity of local response. The blackout, even in the absence of official information so far we know that it was not due to a generation failure but to A chain disconnectionaggravated by a centralized architecture that could not contain the domino effect. This has revived the debate about the need to modernize the network; In that sense, the British model not only stands out for its technical robustness, but also for its regulatory anticipation against high renewable penetration scenarios. How invisible it works. In a world where what fails attracts more attention, it is worth remembering how extraordinary that, despite hundreds of daily technical failures, electricity continues to reach our homes without interruption. As Simon Gallagher concluded: “Everything fails … and yet the lights remain on.” Image | Senate Agr Xataka | Saving the network after the blackout has had a side effect: more expensive light and marketers to the limit

7 out of 10 spectators were last weekend to see ‘Lilo and Stitch to the cinema. It is not as good news as it seems

by

There is no possible discussion: the absolute queen of the box office this past weekend was ‘Lilo and Stitch’, the remake in real image of the animated Disney classic of 2002. In just a couple of days he raised more than Disney had invested in it, and in countries like Spain he has been completely imposed at the box office. Raising, incidentally, doubts about the convenience that there are premieres that dominate the rest with so many clarity. The numbers sing. This first weekend, ‘Lilo and Stitch’ has collected worldwide 341 million dollars. In an unusual but very significant note, practically half of that amount, 157.8 million, has been in international markets. In this way it becomes the second best premiere of the year, just behind ‘A Minecraft movie‘. With a budget of only 100 million dollars to which you have to add up to others in marketing (absolutely key in this case), the business has been round for Disney. In Spain, even more. In our box office, According to Comscorethe thing has been even more triumphant: more than 750,000 spectators have seen it, entering about 5.7 million euros in 1107 screens, that is, the best premiere of the year. Thanks to Disney, the box office receives a welcome oxygen ball, becoming the best weekend of 2025. For comparing, the general box office has been 205% higher than the previous weekend. Without rival. In total, this weekend 8.3 million euros and almost 1.1 million viewers have been raised in all movie theaters. From there, the accounts are simple: 70% of the weekend market share corresponds to titles distributed by Disney in Spain (remember that films such as ‘Thunderbolts’ are still running). That is, the collection of ‘Lilo and Stitch’ is 67% of the Spanish total box office. Or in other words: 750,000 spectators against 1.1 million. 7 out of 10 spectators have seen the Disney movie. La Puntilla: ‘Mission Impossible’. The eighth delivery of the adventures of Ethan Hunt de Tom Cruise has finished rounding a weekend absolutely marked by the blockbusters: the film has entered 190 million worldwide, of which 1.55 million euros have been in Spain. Here is the fifth best premiere of 2025 and they are not absolutely spectacular figures, but we take this into account: of those 3 out of 10 spectators who did not enter ‘Lilo and Stitch’, As the box office expert Pau Brunet saysmore than half saw Tom Cruise’s movie. Short -travel nostalgia. ‘Lilo and Stitch’, regardless of their box office or its limited creative interest, is an interesting exhibition of the state of things: the nostalgia of generation X and millennials, exploited, of millennials, exploited, It is the turn of generation Z. This film is the first to go to the memories of such a young generation: the original film represents the sunset of Disney’s Golden Age, with the advent of Pixar and primed by the last VHS copes, where the sequelae of the film were released. A twilight environment for animation cinema that is now remembered with love. The teddy business. That is why that investment of 100 million euros in marketing makes sense. Stitch’s stuffed animals and dolls have been the great surprise triumph of merchandising of Disney products in recent years: since 2019, annual sales of character -related products have gone from 200 million dollars to exceed 2.6 billion dollars in the last yearaccording to ‘The Wall Street Journal’. And that is just the most visible part of the business: Stitch has become one of the undisputed stars in Disney attractions parks, and the products with the alien face They multiply without rest. The danger of success. Although all this are excellent news for Disney, to the box office (especially Spanish) leaves it in a complicated situation: hypertaquillea films such as ‘Lilo and Stitch’ or ‘Impossible mission 8’ are magnets that attract viewers … to the detriment of the rest of the movies. Although the box office has shot thanks to Disney, 16 titles are distributed Collection crumbs: 474,000 euros. Insufficient to lift a box office that needs the crutch of a couple of Blockbusters To take oxygen, which undoubtedly does not give too many hope about the good health of movie theaters.
