This Christmas I won’t go on a trip without my powerbank. It has a screen and can charge up to a computer

by

I never got around to using the portable battery that I bought many years ago because it took many hours to charge, but a few months ago I bought the Anker Prime Power Bankwhich usually hangs around 75 eurosand the truth is that I am using it a lot, especially for traveling. And for next Christmas I have it clear: it is one of the devices that I am going to use the most. The price could vary. We earn commission from these links A powerbank that I now carry almost everywhere The practical thing about the Anker Prime Power Bank is that it is a portable battery very powerful (up to 200W), so it can be used for a wide variety of devices, whether the mobilewhich is usually the most common, the tabletheadphones and even Compatible laptops like MacBook. Another point to highlight is that it comes with a 20,000 mAh capacitythus allowing devices to be recharged several times. It incorporates a total of three USB ports (one USB-A and two USB-C) and allows you to recharge up to three devices at the same time. At the design level, the most particular thing is that incorporates a screenwhich is quite useful both to see how much autonomy you have left and to check at what power each device is recharging.

The microprocessor that advanced the Intel 4004 was not in a computer, but in a secret place: an F-14

by

We are used to thinking that the history of microprocessors begins with the Intel 4004. Even those who are not experts have it associated with it as the first big chip that inaugurated the era of personal computing. But that is not the only possible story. There was another design, less known and outside the commercial circuits, that began operating before the 4004 reached the market. It did not appear on a computer or calculatorbut in a F-14 Tomcatand for almost thirty years it was invisible to the public. What that plane had inside was a processor designed to do something that no commercial chip did at that time: automatically calculate speed, altitude or wing position while the pilot maneuvered. That system, known as MP944, had been in service since 1970, when the 4004 had not yet been introduced. Its context was completely different from that of Intel, because it was not designed for the market or to be licensed, but rather to fulfill a requirement of the military program marked by the tensions of the Cold War. A secret microprocessor in the bowels of an F-14 The novelty was not only that it made calculations, but that it did so automatically and digitally, something unusual in on-board systems from the late sixties. The MP944 processed sensor readingsapplied aerodynamic equations and provided data that influenced the behavior of the plane, reducing the pilot’s workload. It was not a passive assistant, but a module capable of interpreting those readings and providing results fast enough to be integrated into actual flight control. That is why it was considered a technology ahead of its time. The declassified documents in the nineties show that the MP944 combined advanced MOS technology with a 20-bit parallel architecture capable of executing pipeline calculations, something unusual for its time. Its frequency was 375 kHz and it could process specific mathematical operations efficiently enough to be integrated into real flight systems. According to the figures collected in Holt’s work and in the subsequent review by Tom’s Hardware, this performance placed the MP944 clearly ahead of the 4004 in number of instructions executed, although it was never intended as a general-purpose commercial chip. They were two different approaches: one for a military aircraft, the other for a commercial device. When Holt’s work came to light decades later, He argued that the MP944 should be considered the first microprocessoreven though it was not on a single chip nor had it been marketed. Intel engineers, such as Ted Hoff and Federico Faggin, disagreed and argued that 4004 was the first in integrating all the essential functions of a CPU in a single piece of silicon and with general use. Russell Fish, a former Motorola engineer, reviewed the MP944 documentation and described it as an advanced microprocessor for its time, while Richard Belgard saw it as an overly specific system, designed only to keep an airplane in flight. Holt maintained that the reason no one knew about MP944 for years was because his work had been classified and subject to military restrictions. He said he spent decades requesting the release of the documents and was only able to do so when, in 1997, he won the support of Congresswoman Zoe Lofgren for the Navy to authorize their publication. With the documentation now available, the Navy qualified that version and maintained that Holt’s work had not actually been classified, but that what was missing was the company’s authorization to release the records. Garrett AiResearch admitted that they were no longer clear about what had happened, because the people who managed the case had left the company. When the information became available, Russell Fish claimed that MP944 was so advanced for its time that, had it been known, could have accelerated the development of the sector by up to five years. The creators of the 4004, such as Federico Faggin and Stan Mazor, openly disagreed and pointed out that the merit of the commercial microprocessor was to integrate all the essential elements on a single chip and make it viable for multiple applications. Richard Belgard qualified this position: he recognized the technical value of the MP944, but saw it as a system designed for a single purpose, without the capacity to open its own market. The debate about which was the first microprocessor is not resolved with a date, but with a definition. The 4004 was the first to hit the market as a commercial, integrated and programmable chip, and that merit explains its place in manuals. The MP944, on the other hand, previously demonstrated that it was possible to process data digitally and feed control systems in real time, even if it was done while locked in an airplane and outside of public space. One opened an industry; the other anticipated capabilities. Both represented different ways of understanding what a microprocessor could be.

A company claims to have created the first transparent computer monitor: it has borrowed technology from aviation

by

The idea of ​​“seeing through” the screen is not new. For decades, HUDs have projected data onto the windshields of airplanes. and today many cars offer own versions to show speed or navigation without taking your eyes off the road. That principle, project or reflect information on a transparent elementis the one that Visual Instruments ensures have brought to the desktop with Phantom, a monitor that seeks to mix the digital and the physical and that adjusts its transparency in real time. Phantom does not use a panel that becomes transparent on its own, but rather an optical assembly similar to that of a teleprompter or HUD. The image is reflected in a tilted glass and thus appears to “float” over what is behind, with an opacity control that allows it to go from transparent to opaque. The company presents it as “the first transparent computer monitor.” The key to the invention is in the optics, not in a futuristic panel According to the manufacturer, Phantom is presented as a 24-inch monitor in 16:9 format with 4K resolution. The company sets the brightness in a range from 5 to 5,000 nits and places the color coverage at 100% sRGB, figures that must be confirmed when the product reaches the hands of users and analysts. As for the connection, it is limited to the most common options: USB-C with DisplayPort and HDMIwithout the need for additional software to operate. {“videoId”:”x87bool”,”autoplay”:false,”title”:”How to CALIBRATE your MONITOR for VIDEO GAMES and enjoy it to the fullest”, “tag”:”monitor”, “duration”:”230″} It is worth putting it in context. Transparent screens have been appearing in consumer markets for years. LG has been marketing a 77-inch transparent OLED TV since 2024. Lenovo, for its part, has also developed a concept laptop with a transparent panel. The difference here is key: those products use transparent base panels, while Phantom uses, as we say, HUD-type optics. They are different technological routes, with different commitments and limitations. Aspects such as contrast, color representation with different ambient lights, the presence of reflectionsuniformity or comfort in prolonged use remain unknown. It is also unclear to what extent alternating between the monitor and the background can translate into real relief from eye strain beyond the idea put forward by the manufacturer. Everything will depend on the first independent tests and the measurements that are published when demonstration units exist. In Xataka There is a cheap TV sweeping Amazon: after a week of use it became clear in which situations it can make sense Phantom arrives, therefore, as a suggestive idea that has yet to demonstrate whether it can be sustained in everyday use. The commercial status points to a very early and selective launch. The Founders Edition is limited to ten units intended for early adopters, with shipping expected in Q4 2025, 30-day returns, and a one-year warranty. The price is not final: each unit is custom configured, but the company itself compares it to an Apple Studio Display whose price in Spain starts at 1,779 euros.

Let’s tell you what they are the best antivirus for computerwhich you will be able to use on both Windows and macOS. We have already told you what the best free antivirus or the best online antivirusand now it’s time to go to the paid ones, which you can also use in many cases on your mobile. We are going to start by explaining why you may be interested in using an antivirus on your computer in these times when even Windows has its own. Then, we will go on to tell you some of the things you should Be sure to choose the antivirusand we will end by giving you the nine main alternatives. And as we always say at Xataka Basics, we encourage you to leave us your experiences with these antiviruses and recommendations in case we have left out one that you consider better. Thus, all users will be able to benefit from the knowledge of our xatakeros. Why use an antivirus on your computer Although current operating systems offer their own protection systems that serve to block most threats, cybercriminals are always one step ahead. It’s a constant grind, and by the time one threat is resolved, new ones are already being launched. Thus, new viruses, phishing and malware attacks, as well as zero-day exploits, appear every so often. Third-party antiviruses carry them companies specialized in cybersecurityand therefore its only job is to detect new threats and launch updates for its antivirus with which to protect you. Their reaction time for new threats is lower than that of the operating systems themselves, and that is why they are useful if you want the best security. This does not mean that the antivirus on your cell phone or computer is bad, but that it can be improved with the additional layer of security that these programs offer. The laboratories of antivirus companies are dedicated to monitoring the Internet in search of new threats, checking the data received from their users to detect them, and investigating them in their laboratories to obtain a solution as soon as possible. A modern antivirus not only detects and removes malware, but also protects you against fraudulent URLs, blocks exploits in real time, protects your browsing, monitors your email, and offers you tools against identity theft or malicious encryption of your computer in a Ransomware attack. Therefore, in summary, your operating system offers you basic protection for most threats, but if you want better protection you should use a specialized program. Whether you consider it necessary or not It depends on each of usthe data we keep on our computer and how much it can hurt us to lose it in the event that a virus attacks us. But the tools are there if you consider them necessary. Keys to choosing the best antivirus for your computer Choosing the best antivirus is not always easysometimes it will seem like everyone is offering you almost the same thing. Therefore, we are going to tell you several keys that you should look at when evaluating which one to bet on. royal protection: The most important thing about an antivirus is its ability to detect threats and block them in real time. For this, it is advisable to look at the results of independent laboratories that are responsible for measuring these parameters. Impact on performance: Some antiviruses are lightweight, but others can consume more resources and slow down your computer, especially if it is a few years old. Seek information about this before making a final decision. Extra features: There are antiviruses that offer extras in their prices such as a VPN, password managers, cloud copy systems, parental controls or identity protections. Consider whether these additional tools convince you or if you prefer something with less and a more affordable price. Pricing and renewal policy: Look closely at the price sections. Sometimes you will see additional prices the first year, but then the renewal increases considerably. Others will have more recurring offers, and others may seem more expensive but it will always be the same price. Consider the total price of the renovations and not just the promotions. Compatibility and support: Make sure you are going to pay for an antivirus that has applications for your desktop operating system but also for your mobile if you need it. Also offer customer service in your country. Ease of use: There will be some antivirus that are easier to use and simpler, and others that are more complex but perhaps also more configurable. Evaluate what you need. Reputation and transparency: Search the Internet for cases in which a brand or antivirus has failed, in order to check their reputation and transparency, ensuring that they have not had scandals or controversies over their privacy. The best antivirus for computer (paid) And then, we are going to go with the list of the best paid antivirus that you can install on your computer. For each of them we are going to give you a description with its main characteristics, as well as a link to its official website so you can download it. bitdefender One of the best security software you can find, specializing in dangers such as phishing or ransomware. It also offers an isolated browser for sensitive tasks such as managing your bank, protects you from tracking by ads, and has a password manager. It is available for Windows, Mac, Android and iOS. However, it is not completely perfect, as it does not have such good scores when it comes to blocking malware or defending against malicious web addresses. It offers a VPN, but using it will require a slightly more expensive subscription. Your individual plan has a price of 49.99 euros per yearand can be used on five devices with the same account. Ten euros more for a VPN. Kaspersky Kaspersky is one of the best antivirus on the market, and in all the tests carried out it usually has a score close to or … Read more

A man had access to the Government’s nuclear secrets. Until he uploaded thousands of porn photos to his work computer

by

Using your work computer for personal things is a delicate area that can be reason for dismissal. This worker from the US Department of Energy has discovered it by force after uploading hundreds of thousands of pornographic images on his company computer. What has happened? They tell it in 404Medium. In March 2023, the employee wanted to back up his photo collection. He thought he was uploading the images to his personal hard drive, but it was connected to his work computer and he ended up making the copy where it wasn’t. The problem is that it was not a normal collection of photos, but more than 187,000 pornographic images that he had been collecting over several decades. Although he did not lose his job, his mistake has had consequences and the main one is that he has lost his security clearance. To train AI. The employee defended himself by arguing that this happened during a depressive episode in which he felt “extremely isolated and alone.” One of his distractions at this stage was creating images with AI, specifically “robotic porn.” At first he used his cell phone, but tired of using such a small screen, he thought it was a good idea to upload all his pornographic images to the computer to train the AI. The problem is that he did not upload them to his hard drive, but rather they ended up on the network of a government company. Goodbye accreditation. The employee did not realize his mistake until six months later. It was the time it took his bosses to investigate the origin of that enormous amount of porn photos flooding their servers. The result was that his security clearance was withdrawn. The Department of Energy is the in charge of supervising the US nuclear arsenalso we are talking about access to very sensitive information. The worker appealed to get it back, but after an exhaustive investigation, they decided not to return it. If he had not appealed, the story would not have been made public. My boss spies on me. It is one of the reasons that the man presented in his appeal, which compared the investigation to “the Spanish Inquisition.” What does the law say about this? According to expertsAlthough they let us use it for personal things, we should not expect to have privacy on a company-owned computer. Some companies even pre-install software to measure the time employees work. Control programs. Can they force you to install one of these programs? A few years ago we talked about installing software to control the work of remote employees and Joaquín Muñoz, an expert lawyer in digital law, resolved our doubt: the company cannot force us to install a program of this type if the computer we use to work is ours, but if it belongs to the company they can do so. Of course, they are obliged to report in detail about all the functions of said software.

With AI, Microsoft has once again insisted that we talk to our computer: experience says that we don’t feel like it

by

You get up in the morning, go to work and sit in front of the computer, but the first thing you do is not pick up the mouse and keyboard, but say “Hey, Copilot”. Can you imagine it? Me neither, completely, but that is Microsoft’s clear obsession: to get us to talk to our PC instead of using the usual peripherals. That futuristic vision is striking, but it faces several enormous challenges. what memories. The thing about Microsoft and other technology companies with their intention for us to talk to machines goes back a long way. The first generation of voice assistants precisely pursued that goal. There we saw how Alexa, Google Assistant and of course Cortana tried to make us talk much more with our devices. We were not prepared to talk to machines. Its success was rather limited, and even Nadella himself admitted in 2023 that, for example, those “smart” speakers They were “dumber than a stone”. In Xataka Voice assistants and the fight to gain our trust Cortana tried. The Redmond company certainly tried to make Cortana successful. It offered it on both Windows 10 and on Android and iOS…and even the sadly defunct Windows Phone. Over time the company realized that that assistant was not a good fit, and was killing him little by little. The launch of ChatGPT was used by Microsoft to raise your new assistant powered by AI and definitely kill to his first assistant: Copilot wants to be what Cortana could never be. Who asked for this? With that “Hey, Copilot” the same thing is happening as with Cortana: did someone ask Microsoft to integrate a voice assistant into Windows? The voice assistants of that first generation were relegated to residual use, and Amazon suffered this problem firsthand. He bet billions of dollars that Echos would become devices we wouldn’t stop talking about, but most people I just used them to set timers and music. AI promises to go much further. But in spring 2024 we live in a hopeful moment for this type of technology. OpenAI launched GPT-4o and demonstrated that natural conversations with a mobile phone were not only possible, but also They were very powerful. AI could be ours confidant and companion -with controversy included— or our private teacherand as others later wanted to demonstrate, it could also do things for us just by talking to her. Let them tell you to the vibe coders. But we still have a hard time talking to the PC. Since then it certainly seems that we have become a little more accustomed to talking with our smartphone, but things seem to be different on the PC. The statistics reflect that 77% of young people use their voice on their smartphone, while only 38% of them do so on the PC. “But everyone on the PC listens to me”. There is also a sociological component in this use of voice on the PC. The mobile phone is more intimate and personal, while the PC is often used in a static setting in which there are people around who can capture what we say. Furthermore, in the physical context, the unspoken rules of coexistence—do not disturb, do not invade others’ acoustic space—outweigh the promise of comfort. And then there is distrust. Microsoft is not helped by its recent history, especially with Recall, that option that seemed really striking and ingenious but ended up being delayed to generate a great controversy regarding privacy. The launch of the new Windows 11 options, with “Hey, Copilot” as the main protagonist, does not seem to have been received with too much enthusiasm, and the tone, for example, of the comments from this long thread It is skepticism. Rivals focus on mobile phones and speakers, not the PC. The truth is that the adoption of voice as a way to interact with our devices does not seem to be particularly viral. The erratic launch of Alexa+ does not seem to be providing great advantages, Apple continues to make itself wait with its renewed version of Siri, and only Google has taken a step forward with Geminialthough not clearly on the desktop. Talking to machines works, but not as much on the PC as on the mobile. {“videoId”:”x9jvzns”,”autoplay”:false,”title”:”Project Astra Exploring the Capabilities of a Universal AI Assistant”, “tag”:”Project Astra”, “duration”:”116″} A triumph for accessibility. Where there is a clear use scenario for this technology is in the area of ​​accessibility. For users with reduced mobility, the ability to dictate or control the device with their voice can be transformative. This need is concrete and well defined, however: it does not justify a general redesign of the interaction or a marketing campaign that tries to get us all to talk to the computer. The voice should solve things, not be a fair trick. Microsoft’s real challenge is not technical — the technology is there — but human. The company must convince people that talking to the PC makes sense. To do this, it must address three fronts: privacy, the social context—that you don’t mind talking to your PC—and of course, that said interaction has practical use and works. For example, they come in there Copilot Actionswho will have to demonstrate – like everything else – that Microft is on the right path here. Otherwise, “Hey, Copilot” could become the new Cortana.

break the computer market

Apple has done very well The transition to Apple Silicon. Your products, widely well valued for their power and efficiencythey have managed to sell very well, which has made the company go from 5.8% world market share to 8.7% of the first quarter of 2025, according to IDC figures. In Cupertino they want more, and the last plan to enhance sales goes through A cheaper macbook. Filtration. Ming-Chi Kuo is one of the analysts who has the best history of successes in terms of rumors of upcoming Apple launches, And predicted that the company prepares a cheaper “macbook” and colors. There are no surprises on the screen: it would be “approximately 13 inches.” However, it points to something they had not yet done from Cupertino, using an iPhone processor in a Mac. And Apple would choose the A18 PRO with which the iPhone 16 Pro and 16 pro max. The price. Digitimes, another medium with very good sources with regard to Apple, has gone further that Kuo and already offers a tentative price for this launch: $ 599. It is the same price chosen by Apple to market the cheapest MAC in history by adjusting for inflation, the Mac Mini M4. And also the same as iPhone 16E. In both products, the Spanish price without discounts is 709 euros. And that price would be groundbreaking for the global PCs market, such as It has been for smartphones. To put the figures in perspective. Apple’s “cheap” macbook, antonomasia, was launched at $ 1,099 in 2006, which implies a price of about $ 1,700 of 2025 updating inflation. Adjusting the price of that model to euros of 2025, the “blanquito” stays at 1,569 euros (and it must be remembered that VAT was 16% until its rise in 2009). Apple’s cheapest laptop sold in Spain was the 2009 variant, marketed for 879 euros (1,215 euros of 2025). Why it is important. Apple has managed to hit a bite to the PC market with very competitive laptops in its segment like the MacBook Air, especially Now that they are already base equipped with 16 GB of RAM. And he has achieved it without teams considered economical, but with the lowest prices in its history. Rancing an economic macbook at Mini prices, Apple would sell between 5 and 7 million units in 2026, according to Kuo. The Macbook Air M4 starts from $ 999, the same as the M1 departed and previous models with Intel. But adjusting inflation, its price is lower than those. The MAC Mini M4 is now 599 dollars, compared to $ 825 by adjusting the inflation of the original MAC Mini, which reached the market in January 2005 by 499. That just is the price at which they sell the Mini M4 for the educational market, where this new team would have a huge asset given the capabilities of the team. “A nightmare for Microsoft“In Windows Central They have it clear. The $ 599 are bad news for a Microsoft that in October faces one of the critical moments of the decade: The end of Windows 10 supportthat still has more users than Windows 11 in countries like Spain, and hundreds of millions of users in the world. Given this situation, Microsoft Clara: Buy a new PC. In the market there is no PC that offers the lightness, power and efficiency that Apple aims to have in its economic MAC, and Similar proposals with Snapdragonthe chip that rivalize with mthey are in a few more euros. At the peak of the 400 euros netbooksApple presented its own alternative, the iPad. Steve Jobs said there was no place in the company’s family for economic laptops. When launching the iPad, Jobs explained why they did not launch a cheap laptop (netbooks, at the time) for being slow and having poor quality. In 2025 there is not so much sacrifice. Iphone brain, more than capable for a Mac. The fear of reading “iPhone chip” is that it is not powerful enough to move macos (and their needs) with ease. The reality is different, if we attend to the numbers. Currently, an M1 chip remains more than enough to perform even heavy tasks in the system. And the A18 pro is more powerful in any CPU metric: A18 PRO M1 Difference in favor of the A18 Pro Geekbench 6 (single core) 3429 2345 +46.23% Geekbench 6 (Multi Core) 8790 8348 +5.29 % Geekbench 6 metal (GPU) 32686 33073 −1.17% 3DMark Steel Nomad Light Unlimited (GPU) 1541 1892 −18.55% In GPU, as we see, using metal, it is somewhat less powerful. And in a gaming test executed in equal resolution, such as Steel Nomad Light Unlimited, the A18 Pro is left more than 18%. In Single Core, the A18 Pro is also more powerful than the M2 and M3. And that is the most relevant section to move an operating system with ease, as well as what we do most today with the PCs, navigate the web. Prepared for AI. Although the A18 Pro and the M1 have a 16 -core neural Engine, the advances in architecture and in lithography of the iPhone chip allow obtaining From 50% more yield until the triple of the M1 offers the same processes. Clearly, except for Gaming, we are facing a more suitable chip for the needs of computer science in 2025. Huge autonomy potential. M1 is a legendary chip for The autonomy that brought the Macbook Air and Pro They arrived equipped with him. If Apple does not cut in the old air watts, the gain in autonomy can be immense, as the A18 PRO is manufactured by TSMC in the second generation 3 NM node (N3P), compared to the 5 NM first generation of the M1. Yes, but. A Macbook with an A18 Pro sounds very good, until we remember that it would be launched with an economic approach, and that in Apple usually comes accompanied by cuts, sometimes irrelevant, and sometimes painful.

How to install Openai’s new Got-Oss models on your computer to have your own chatgpt at home

by

OpenAi has announced New models Open Source that anyone can download and install on their computer: GPT-Oss. With these already on the street, it is an excellent opportunity to start stirring with the The premisesthat is to say, Executed on our computerso today we are going to teach you to install and use them. Differences between the two models Although they are called in a similar way, GPT-Oss-120B and GPT-Oss-20B are not exactly the same nor have the same requirements. The first model, GPT-Oss-120b, reaches a parity near OpenAi O4-mini and requires at least 60 GB of graphic memory. Having your own chatgpt at home is easy, but it requires a team at height | Image: Xataka His little brother, GPT-Oss-20B, is somewhat less capable (similar to O3-mini, according to OpenAI), but can be executed on devices Edge. In other words, it can be executed on your own computer whenever it has at least 16 GB of memory, preferably graphic. In summary: GPT-Oss-120b: Large model, need at least 60 GB of vram or unidicada memory and is not suitable for consumer computers. GPT-Oss-20b: smaller model, need 16 GB of vram or unified memory and is suitable for consumer computers. The one we are going to use, for obvious reasons, is GPT-Oss-20b. Considerations to take into account Executing an AI like in local is an intensive process that can cause, and surely cause, that your computer slows down a lot. Although you could execute it having 16 GB of RAM, the ideal is that your team has A high -end GPU. What will happen if your computer has less than 16 GB of vram memory? Than the tool will use RAMwhose figure must be equal to or greater than 16 GB. If not, the system will not work properly. As a general recommendation, the ideal is to dedicate all the possible resources of your computer to the execution of the model, so it closes everything that is not strictly necessary. Install Ollama on your computer OLLAMA Installation | Image: Xataka For this tutorial we will use a well -known application: Ollama. It is an Open Source platform that simplifies, and much, the installation, access and use of LLMS (Large Language Models). Let’s say he is an executor of models. Chatgpt is an online platform through which we interact with a model, such as GPT-4O. Ollama is the same, But at home and with the models we have installed on our computer. It is a free, open source software and available for Windows, Mac and Linux. Download GPT-Oss Once we have downloaded and installed the program on our computer we will find an interface like this. If you wish, you can also use ancient ollama through the Command interfacebut the truth is that the graphic interface is much more pleasant. Main interface of Ollama | Image: Xataka If we look, we will see a drop -down in the lower right area with the name of the model we are using or that, rather we will use. Access to the different AI models from Ollama | Image: Xataka If we click on the drop -down we can access a good handful of models, such as Deepseek R1, Gemma either Qwen. In the case, we are interested in selecting “GPT-Oss: 20b“ Download of the model, armate of patience | Image: Xataka Having selected “GPT-Oss: 20B”, it will be enough to send a message in the chat to begin the download of the model. At patience, because it weighs 12.8 GB and can take a while. Talking to GPT-Oss-20b through Ollama | Image: Xataka Once it is installed, you can start talking with AI as if it were Chatgpt. Of course, if your GPU does not meet the minimum requirements you will see that it is much slower than chatgpt. Not surprisingly, you are running the model on your computer, not in a data macrocenter full of the latest in Dedicated Gpus of Nvidia. Another option: LM Studio Lm Studio | Image: Xataka Ollama has the advantage of being intuitive, simple and direct. If we want more options, a much more complete program is LM Studio. This is available for Windows, Linux and Mac and, as Ollama, is able to manage several models, GPT-Oss: 20b among them. It is a more advanced application that allows us to better adjust both the behavior of our computer and that of the model, although squeezing it to the maximum requires more advanced knowledge.

In 2030 he plans to have the most powerful quantum computer that exists

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, there is a country that has officialized its intention to lead in the medium term both in the field of Quantum computing as in the manufacture of semiconductors: Japan. In the middle of last April we tell you that the Riken Center for Quantum Computing and Fujitsu had just announced that they had developed in a joint project A superconductor quantum computer endowed 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. However, Japan’s plan in the field of quantum machines does not end up here. And it is that in 2030 it intends to have a quantum computer 25% more powerful that the most capable that IBM will have at that time. 250 logical cubits to make a difference The design and tuning project of this ambitious quantum machine is already underway. And the Riken Center for Quantum Computing, Fujitsu and the National Institute of Advanced Industrial Science in Japan. This quantum computer will use superconductor cubits and a very advanced cooling system, presumably a dilution system similar to the employee by The machine they presented in April. Whatever your best asset, if you finally get to fruition, it will be its 250 logical cubits. Each logical ul Logical cubits represent a way to overcome the difficulty involved in the use of hardware or physical cubits, which are extremely noise sensitive, and, therefore, prone to make mistakes. Each logical cubit is constructed in an abstract way About several physical or hardware cubitsso that a single logical cubit encodes a single cubit of quantum information, but with redundancy. It is precisely this redundancy that allows to detect and correct the errors that are present in the physical cubits. Until very recently the number of hardware cubits that was necessary to implement a single logical cubit immune to errors was impracticable, but IBM says that he has found the solution To this problem. And presumably Fujitsu and the Riken center too. IBM is going to build The quantum computer ‘Starling’ in a new data center that will be housed in Paughkeepsie, New York (USA). This machine will bring together 200 logical cubits that, in theory, will allow you to execute 100 million quantum operations. IBM says that ‘Starling’ will be ready in 2029but, as I mentioned a few lines above, Fujitsu and Riken intend to have their quantum machine of 250 logical cubits in 2030. If they get it, they are likely to lead in this field. In any case, before that milestone arrives, much earlier, in 2026, they pursue to be ready A 1,000 cubits computer. They will not be 1,000 logical cubits; They will be 1,000 conventional cubits, and, therefore, prone to make mistakes. Even so, if Japan get it, only one step from the US and China will be placed in this field.

Years ago I bought a computer that turned out to be a chestnut. Almost for the same price, this gives three (or more) turns

by

A few years ago (not too many) I bought a computer that would be destined to work exclusively. It turned out to be a bit brown. I spent approximately 620 euros and, although I did not have a bad technical card, the experience was very different from what I expected. Times change and today for that price we see very interesting offers, but few like Mediamarkt’s. Only today, the store has the Gigabyte G6 For alone 660.45 euros. And much eye at its configuration. Of course, it is worth mentioning that, although the computer already has a direct discount, We can take an additional discount. Just add it to the shopping cart to find it at the price of 660.45 euros (compared to the 777 euros that appears before adding it to the cart). * Some price may have changed from the last review Excellent configuration in a pretty cheap gaming laptop The Gigabyte G6 that we find of offer in Mediamarkt is a Gaming laptop which has an excellent configuration in this case. First, assemble a good 16 -inch screen that offers A Full HD+ resolution and a 165 Hz soda rate. To this we must add that internally comes equipped with the processor Intel Core i7-13620h together with 16 GB of RAM and 512 GB of internal storage. In addition, it also includes a graphics card NVIDIA GEFORCE RTX 4050 To enjoy virtually any video game. Among other things, it is worth mentioning that it comes with the Freedos operating system (it does not come with Windows 11 Home) and includes a wide repertoire of connectivity options: several USB-A ports and many other USB-C, 3.5 mm Jack, Mini Displayport, Ethernet and even microSD card reader.
