A VPN is your ally to win at home security, but above all outside. This surfshark now has almost 90% discount

by

There is no exaggeration that is worth: we live on the Internet. Much of the day we spent connected, through the browser or other applications such as social networks. Internet is a very useful window, but also houses certain inherent dangers that are difficult to control. In fact, data leaks are the order of the day, such as The one that has suffered El Corte Inglés. If we want to pay in an online store or put our data on some Internet portal we are exposing ourselves to suffering attacks. This is even more delicate if we use A public wifi network Or that of a hotel, for example. The best thing we can do is use a VPN And this surfshark comes out now at a difficult price to reject: 2.19 euros a month. Surfshark Starter Subscription – Monthly * Some price may have changed from the last review Surfshark can be used on all the devices you want It is true that there are free options when looking for a VPN, But most offer a slow and limited service. The investment that Surfshark requires now is so small that it values ​​its service, since it allows us to enjoy a much safer experience on the Internet for very little per month. One of the most interesting points offered by this VPN is that it allows us use it on all the devices we want With the same account, whether computers or mobile phones. We can always take it on the mobile and, if we go on a trip, we will have it there in case we need to connect to a network of which we do not have any information. Surfshark VPN is included in its Starter Plan, which is the one that has the price at which we refer a little higher. This package, the most economical of the three you have, It also comes with another very useful tool: Alternative ID. This allows us to create a series of fictitious data in case we want to register on a website and we do not want to use our real information. This pack has a price right now 2.19 euros A month, which means that two years of the service leave for a total of 55.56 euros. It is a real discount, since without this offer the same period of time costs 439 euros. And there the thing does not end, Since surfshark also gives us three additional months.

AI is already our best ally to solve the mathematical problems that seem impossible

by

The applications of the artificial intelligence (AI) are presumably unlimited. Beyond the daily uses with which many of us are already familiar with the design of drugs, Disease diagnosisthe OPTIMIZATION OF INDUSTRIAL PROCESSES or the Analysis of physical or chemical mechanisms complexes, among other options. It is even being used to solve mathematical problems of enormous difficulty. In addition, algorithms that use deep neuronal networks and Automatic learning They are designed to identify complex patterns in large volumes of information, which allows them to recognize images, voice or process natural language greatly. AI has reached our lives, and it is clear that it will stay, but the most surprising thing is that it is consolidating as an extremely valuable tool in relatively exotic fields. It is possible that AI helps us solve the mathematical problems of the millennium In October 2024 Goal AIMeta’s artificial intelligence, managed to generalize Lyapunov’s function. The Russian mathematician Aleksander Lyapunov proposed the concept of the function that bears his name in 1892. His work is a very important tool in the study of dynamic systems, but mathematicians have since struggled to find a general method that allows identifying the functions of Lyapunov. And they have not been successful. However, goal has had it. Our mathematical knowledge will no longer be limited by intuition and human capacity The strategy used by the company led by Mark Zuckerberg to solve the challenge of Lyapunov’s functions has consisted of training an AI model to recognize patterns and relationships between certain dynamic systems and its corresponding functions of Lyapunov. This is precisely what is good for AI. And it is a huge success because our mathematical knowledge will no longer be limited for intuition and human capacity. The AI ​​puts in our hands a new way of addressing complex mathematical problems, identifying patterns that a priori remain hidden for the human being. However, in the field of mathematics AI still has to improve to help us solve the great challenges that the human being has ahead. Sergei Gukov, professor of theoretical physics and mathematics at the California Institute of Technology (Caltech), leads a team of researchers who is looking for ways to use AI to solve advanced mathematical problems that require thousands, millions, or even billions of steps. These scientists are currently working on The conjecture of Andrews-Curtisa group combinatorial theory proposed 60 years ago. They have not yet managed to solve the main conjecture, but with the help of AI they have achieved something important: they have refuted several families of problems related to the conjecture of Andrews-Curtis and known as counterexamples that have remained open for more than 25 years. Gukov acknowledges that Current AI models have important limitations When facing very complex mathematical problems, but you hope that in the future this technology allows the human being to solve Mathematical Millennium Problems. According to this mathematician, the best asset that researchers have to face this challenge is to instruct AI by resorting to Reinforcement learning.

LG wants to take the customization of TV to the extreme and has found its best ally at AFO

by

With the importance of streaming, Choose a SMART TV with a quality operating system It is not trivial and it is no novelty that Webos LG is one of the best. Based on Linux, the SO implemented by the Korean firm stands out for its fluidity and ease of use thanks to an attractive and agile interface, as we have been able to verify over the years in our analysis of models as remarkable as the LG QNED87, LG OLED C3 either LG Signature Oled M. The latest version of the operating system of LG is webos 25 and we have had the opportunity to try it now in the New Korean firm’s teles for 2025. However, it should be remembered that LG offers a five -year update supportso there will be other models of previous generations that can enjoy this update Following the brand’s calendar. Webos 25 arrives full of artificial intelligence and more personalization New LG TVs by 2025 with its renewed command, Remote Control AI Those who are familiar with Webos The image of this new version will be familiar to them as long as LG has opted for Maintain an intuitive design and interfaceusing cards that are placed in the lower area of ​​the screen, which in turn can reorganize to taste. It also allows to close applications and keep them in the background to recover them quickly from the lower bar. This SO It has serial activated advertising which will also continue in the latest version, although as always, it can be withdrawn (from ‘additional configuration’> ‘Home promotions’). And once the bases are cooling, the news arrives. The profiles and everything that can be done with them It is one of the great novelties of Webos. Taking into account that the normal thing is that the TV is used by several people, if we give the relevant permits, it will generate different personalized starting screens according to our tastes, adjustments and content preferences. Thus, each profile will have its own applications (they can be hidden for other people, but not eliminate: in that case they are deleted for everyone), suggestions and recommendations and tells us where we have stayed in that specific content. Although it can be chosen through command, it is not necessary since is able to recognize who is through voice by Voice ID. A concrete example of Personalization through profiles It is that of the ‘Sports’ section, where for example we can tell you what team we are so that it shows us content of ‘My team’ and related suggestions, such as Highlights YouTube videos and interviews or when the next game will be. This customization experience It is not limited to content consumption, but it reaches all the layers of webos 25. If we go to the games section we can see which titles we play and what are our achievements and on the home hub screen for home automation we can also control the compatible devices connected and execute certain routines. Nevertheless, Webos 25’s great novelty is artificial intelligencewhich will be present in the most diverse tasks ranging from the optimization of image and sound quality, accessibility adjustments, recommendations and even conversations with natural language and contextualization through the button of the AI ​​remote control, remote control AI. Thus, it is enough to hold that button to Start talking to TV naturally. Thus, you can ask things like what was the last film we saw, content recommended based on certain preferences (yes, limited to platforms with which it collaborates for this function) or until it tells you to suggest films where New York comes out, since we have planned a trip close to that American city. LG has also integrated an entertaining and different function, the generative ai gallery, a way of generating images through AI on the quite paint but limited television itself. Experience is somewhat slower than navigation without more but equally moderately fluid and contextualization is good. But beyond recommendations, on a practical level The most differential of AI is that you solve problems. For example, you can tell you that you see the screen too dark and that TV itself helps you adjust it for a better viewing or directly, that optimizes the configuration. Although the total deployment of the artificial intelligence of Webos 25 is necessary to have a state -of -the -art model with its remote control, LG has integrated Microsoft Copilot For a more general task: the search for information through the Internet.

Kaspersky’s premium plan has everything to be our best ally when we are going on vacation

by

When one goes on a trip, he always focuses on not forgetting the most important things: documentation or mobile, for example. When we are there we will want to connect to the Internet, either at the hotel or with a public wifi. This type of networks offers very little securitywhat can be a great danger. To avoid problems, better with a VPN installed on the mobile, and if it is better quality. The one that Kaspersky has in his premium plan is a great option, more now that we have it reduced: One year of the service only leaves for 34.99 euros. Kaspersky Premium – Annual * Some price may have changed from the last review Investing in a VPN is to win in security for our data When we use a public network or a network that we do not know, we risk any hacker that can monitor everything we do. This is something for nothing crazy and that can happen at any time, especially when we go on a trip, where we are always going to connect to unknown networks. There using a VPN is vitaland although there are free options, we can bet on a payment to win an additional extra security layer. We almost always recognize Kaspersky as an antivirus, although his premium plan offers this and much more. With him, we will have with us a VPN that will allow us sail safely every time we go on a tripeven if we want to consult our bank information. It can also come well if we want to access any service that is not available in the country in which we are, as can happen with WhatsApp video calls. This plan also has other very interesting tools to travel safely. One of them is the protection of our personal data, storing our passwords in a private repository with good security. And not only for us: This plan includes a free year of safekidsperfect for our children to navigate safely. Kaspersky Premium – Annual * Some price may have changed from the last review This plan is priced at 79.99 euros a year, but right now we have it with A 56% discount. Thanks to it, we can enjoy a year of the service for only 34.99 eurosa great figure. In addition, we can cancel the subscription at any time, so we will not be tied to the service with any permanence.

Nvidia has a very strong and not quite unexpected ally against Depseek: TSMC

by

Deepseek has convulsed the industry of the artificial intelligence (AI). The irruption of this free and open source Chinese model has questioned the need to use in training and inference processes Chips for very powerful and expensive. Like those designed by Nvidia, which leads with an unappealable roundness the hardware market for Ia. Even so, just ten days ago Deepseek caused Its market value fell abruptly. Since then the hardware used by this Chinese company has generated a lot of distrust. The Deepseek responsible argue that the infrastructure they have used to train their agglutin model 2,048 chips H800 of Nvidia. And that this process with 671,000 million parameters has cost 5.6 million dollars. However, some analysts defend that these figures do not reflect reality. The very juicy report prepared by SEMIANALYSIS He maintains that, in reality, the infrastructure used by Deepseek to train his AI model approximately 50,000 NVIDIA GPU with Hopper MicroAritecture. According to Dylan Patel, AJ Kourabi, Doug O’Laughlin and Reyk Knuhttsen, at least 10,000 of these chips are GPU H100 of Nvidia, and at least another 10,000 are GPU H800. The remaining chips, according to these analysts, are the cuts cut H20. The TSMC cowos packaging is a very strong support for Nvidia As we have just seen, at the current situation it is reasonable to have doubts about the hardware that Deepseek has used in the training of its model (in inference seems to be using the GPUs Ascend 910c of Huawei). And also about the real cost of this process, which could be much higher than the officially announced by this Chinese company. In any case, Depseek has poured uncertainty about the AI ​​market, and this is the reason why so many US technology companies have lost value. Whatever Nvidia has just received a very strong support from TSMC, which is the semiconductor manufacturer that produces its GPU. And is that, according to Digitimes Asiathis Taiwanese company has decided launch an expansion plan five years long for integrated circuit manufacturing capacity using its advanced cowos packaging technology (Chip-on-Wafer-on-Substrate). According to Beth Kindigof the I/O Fund consultant, this technology will monopolize between 50 and 60% of the market in 2025 compared to 15% it supported during 2024. In 2024 TSMC he officially announced that he was building two cowos packaging plants in the town of Chiayi, housed in southern Taiwan The high demand for GPUs for AI with Blackwell MicroAritectura de Nvidia is largely responsible for the implementation of this plan. The company led by Jensen Huang can respond better to the needs of its customers and will see how its competitiveness is increased in a phase in which Depseek and other Chinese companies represent a challenge. In March 2024 TSMC officially announced which was building two cowos packaging plants in the town of Chiayi, housed in southern Taiwan. However, this is not all. He also shuffled the option to put a plant more specialized in this advanced packaging technology in Japan, presumably on the island of Kyushu, in which This company is building at the moment two semiconductor production plants of avant -garde. In any case, there is something else. And it is that Chiayi plants will be trained to work, in addition to the packaging cowos, with advanced Info and Soic technologies (System on Integrated Chips). It is evident that TSMC wants to cover your back well and look to the future to prevent its production capacity from being threatened by a bottleneck. An interesting note: currently the Cowos packaging is being used with the AMD Instinct Mi250 chips and with the A100, H100, H200, B100 and B200 NVIDIA GPUs, as well as in its derivatives. The review used in these last two chips, the B100 and B200, is known as Cowos-L. In 2025 TSMC will be able to process no less than 60,000 wafers per month using its advanced packaging technology.
