by

Let’s explain to you how to create an interactive multiple choice game to help you study anything. We are going to do it with Claudeand you will only have to upload any PDF with the theme you want, and the artificial intelligence It will process its content and ask you questions about it. For this we are going to use the Claude’s artifactswhich means that they will be fully interactive games. In our case, it will be a test type, with several answers of which there is only one valid. So, if you click on the correct answer it will tell you that it is true, and if you click on the incorrect one it will correct you by giving you all the information about why it is not like that. The positive part of using Claude is that you only need a prompt and it will generate the game artifact for you. However, you should keep in mind that all PDFs you upload will be processed by AI, and that could be stored on servers of the company. Therefore, be careful about uploading files that contain private information. You should also keep in mind that AI is not infallible, and that there may be errors and hallucinations, so it is advisable to verify the answers by other means. In addition, you must also make sure that the PDFs you upload have accurate information. Create your multiple choice question game The only thing you have to do to create your game is write a prompt with which ask the AI ​​to create an artifact and describe the type of game what you want You can start with something simple like the following: I want to create an artifact. This artifact will take the information from a PDF that I upload, and will generate a series of multiple choice questions to learn the content. You will do this using Claude, who will analyze the content of the PDF, detect the most important themes and then generate the questions. Once you write the prompt, Claude will generate the game in a few minutes. At the top prompt you can specify anything you want about the game, both specific mechanics and adding a scoring system such as the number of questions or even the colors of the buttons. Then, on the left side, a window will open where you will be able to start your game. For that, the normal thing is that you simply click on the indicated option and upload the PDF from which you want the questions to be generated. Then, in my case I had to choose the number of questions, and then click on the start button below. When you upload the content and start the game, Claude will begin to analyze the content of the documentunderstanding what it says and based on its information to generate questions. After analyzing the content, the game will start asking you questions. As we have asked it to be a test typeit will ask you questions with several possible answers, and you will have to click on the one you consider to be the correct one. If you got it right, it will tell you. But if you fail to choose the correct answer, it will also indicate the failure. In my case, below the correct or incorrect answers, a fragment of the text appears in which it tells you the correct answer. It is not necessary to stay with the first result. If when you try it you are not convinced, you can return to the conversation and ask Claude for changesspecifying the things you want to change or those you want to add or remove. It will then regenerate the artifact from scratch with your instructions. Save your device to use whenever you want Once you have the device to your liking, in the upper right part of the screen you must click on the down arrow button next to where it says Copy. When you do it, click on the option Publish artifact. This will upload your creation to the servers and keep it saved. By publishing your artifact, anyone will be able to find it, and you will also be given a link to share it. But most importantly, in the artifacts section there is a tab Your artifactsand when you click on it you will see all those that you have created. This will be a good way to reuse the game you created whenever you want. In Xataka Basics | Claude: 23 functions and some tricks to get the most out of this artificial intelligence

How does this number of questions about housing work and what is it for?

by

Let’s tell you What is telephone 047 and how does it work?. This is a toll-free government telephone number to make inquiries related to housing, and it comes into force from February 2026. With this number, the Government tries to offer citizens a reliable and truthful way to resolve any doubts they may have about housing, but also advice regarding possible conflicts. Let’s explain everything to you. How telephone 047 works The telephone number 047 is intended to access accurate information related to housing. Come on, if you have any questions related to legal or technical aspects of the home, you can call and ask about your rights and obligations. In this number you can make inquiries about topics such as rentals, sales or problems of coexistence with neighbors. You may also ask about urban leases, horizontal property, eviction procedures, prevention mechanisms, social housing and situations of vulnerability or legal protection of tenants. This phone also offers legal advice and support against market abuses. If you believe that your rights are being violated, you can call for help. For this legal part, the Ministry has the collaboration of the General Council of Lawyers of Spain (CGAE), which brings together 83 professional associations promoting arbitration and mediation methods. The idea is that mediation can be done to avoid going to court unnecessarily when there are conflicts. There are three levels when answering calls. The first level of attention is for basic consultations on the first call, those that are about general issues regarding rights and obligations regarding rental, property and cohabitation. It is expected that the first level can resolve between 90 and 95% of calls. There will also be a level for more specific and less general questions, such as those about specific cases or specialized areas. And there will also be a level to help with legal support or legal advice related to conflicts regarding housing. This advice and advice will be extrajudicial, meaning it will not be helped if the conflict is already judicialized. This number will be available to all Spanish users, regardless of the telecommunications company we have contracted. We will simply have to dial 047 without any type of prefix or anything else, and you will be put in contact with the helpline. Initially this service will have 25 people of different profiles and levelswho are the ones who will answer the calls. Among them there will be lawyers and personnel with specific training in housing matters.

All the unanswered questions left by Netflix’s purchase of Warner: a huge mess

by

After a few weeks of three-way negotiations, it is finally Netflix that has won, with $82.7 billion ahead, take over Warner Bros.. Which includes, of course, HBO Max, but also the entire production arm of the veteran company, one of the few majors classics that remain in Hollywood. However, the purchase is of such importance that a multitude of questions arise, many of them still unanswered. This is everything we know (and don’t know) about this absolute revolution in the world of streaming. What we do know. Netflix and Warner Bros. Discovery have announced an agreement that radically transforms the entertainment industry. The operation, which is expected to close between the end of 2026 and the beginning of 2027, unites the streaming giant and its more than 300 million subscribers with one of Hollywood’s most legendary film studios, founded more than a century ago. For now, Netflix must wait for CNN and Discovery to finish separating from what was their parent company. And now, the doubts. What will happen to Warner’s classic IPs and franchises? Netflix takes over a trove of intellectual property that includes the DC universe‘harry potter‘, ‘game of thrones‘, Looney Tunes, Scooby-Doo and the distribution rights to franchises such as ‘Dune‘ or the Monsterverse. It also acquires film classics such as ‘The Wizard of Oz’, ‘Casablanca’ and ‘Citizen Kane’, as well as emblematic HBO series such as ‘The Sopranos’, ‘The Wire’ and others close to the platform such as ‘Friends’. Netflix will most likely keep these franchises active and continue them. The company has stated in its statement that these IPs will allow “creating greater value for talent, offering more opportunities to work with successful intellectual property.” The big advantage for consumers is certainty: One of the fiercest criticisms of Warner Bros. Discovery under David Zaslav was the removal of content from HBO Max for tax reasons. Netflix has opposite incentives. Who knows…and if we get to see ‘Batgirl’? What has Netflix not bought and what Warner divisions and businesses are not included in the purchase? The deal completely excludes Warner Bros. Discovery’s global networks division, which will be spun off into a new company called Discovery Global. This spin-off has been planned since June 2025 and will be completed in the third quarter of 2026, before Netflix can close the acquisition, and includes assets such as CNN, TNT Sports in the United States, all Discovery channels (Discovery Channel, HGTV, Food Network, TBS, TruTV), the main free-to-air television channels in Europe, the Discovery+ streaming platform and Bleacher Report. This split makes strategic sense: Netflix has never shown interest in the traditional linear channel business, which is in structural decline. In fact, revenue from Warner Bros.’ cable television division. fell 23% in the last reported quarter. Netflix stays with what really interests it: production studios, content libraries and HBO Max. Are HBO Max prices going to rise? The most immediate answer is that most likely yes, although not immediately. Netflix has a documented history of regular increases: Since 2017, the platform has raised its rates by approx. every 18 months. The most recent one occurred in January 2025. However, the arrival of HBO Max changes the equation. When Disney acquired Fox in 2019 for 71 billion, Disney+ increased its price by 129% between 2019 and 2025. We must not be naive: with 302 million global subscribers after acquiring the 128 million of HBO Max, Netflix would exceed 420 million, a huge base where small increases will generate billions of dollars in additional income. Our bet: a single premium price between 20 and 25 dollars/euros per month by 2027, when the deal is underway. What does Netflix get apart from the catalog? Beyond content libraries, Netflix acquires monumental physical and operational infrastructure. You get the historic Warner Bros. Studios in Burbank, California, a production facility that has been operational since the 1920s and includes multiple sets and top-of-the-line technical equipment. The company has emphasized that this will allow them to “significantly expand American production capacity.” Perhaps most transformative is the global theatrical distribution apparatus. Warner Bros. has deals with networks around the world, a network that Netflix has never fully developed. Netflix will inherit “a global distribution apparatus” which includes contracts, commercial relationships and an army of professionals: human teams made up of executives and creatives with decades of experience. Will you take advantage of it? Netflix has promised maintain “Warner Bros.’ current operations, including theatrical releases for films,” but frankly, and seeing Netflix’s relationship with theaters in recent years, there is reasonable room for skepticism. How is Netflix’s presence on HBO going to be creatively noticed? Speculative territory, but we can reason from the corporate cultures of each platform. HBO built its reputation through a creative process where pre-production is vital, with constant rewrites and only the best series receiving the green light. A meticulousness that has historically paid off, for example, at the Emmys. Netflix is ​​just the opposite: it renews and cancels without stopping, trying many things and sticking with what works. Possibly we will see a hybridization where HBO maintains its distinctive seal of quality, less fast food than Netflix, but accelerating production rates. As a curious note, in the presentation in London to which We attended just a couple of days ago The current CEO of HBO, Casey Bloys, highlighted the differences in creative approaches with Netflix as one of its strengths. Maybe everything will change from now on. What legal problems may arise for the purchase? The regulatory hurdles are substantial. The combined entity would exceed 420 million global subscribers, giving it more than 30% of the streaming market, a threshold traditionally considered problematic in US antitrust law. Republican Representative Darrell Issa warned this month that Netflix already possesses “unmatched market power” and that adding HBO Max “could result in harm to consumers.” Senator Mike Lee was more forceful, declaring in X that this transaction “raises serious competition issues, perhaps more so than any transaction I have seen in a decade.” Netflix … Read more

Elon Musk is trying to win the AI ​​race by creating the Wikipedia of AI. We have many questions

by

Grokipediathe new online encyclopedia created by xAI, is now available. The project that Elon Musk has been talking about for some time is just what we expected: a version of Wikipedia in which the content has been generated by Grok, the AI ​​model developed by Musk’s company. And that is precisely the problem. What is Grokipedia. Basically, a copy of Wikipedia in which, as we say, the writing of the texts is done by Grok. The design is simple, with a home page that is a search engine. The articles follow the design of Wikipedia and its structure of different headings and photos. At the moment there do not seem to be any photos in those articles, and Grokipedia does not currently allow users to edit those pages either. If AI makes mistakes, how can we trust AI? The essential question that determines the validity of the idea of ​​Grokipedia is precisely that. Considering that AI makes things up and makes mistakes, what can you expect from an online encyclopedia created by an AI model? Grokipedia on the left, Wikipedia on the right. The PS5 article is an absolute copy of the Wikipedia original. Content “adapted” or directly copied from Wikipedia. Some Grokipedia pages display the message that the content has been adapted from Wikipedia taking advantage of the Creative Commons Attribution-ShareAlike 4.0 license. This happens, for example, with the article dedicated to MacBook Air. In other articles such as that of the PlayStation 5 That message falls short because the article is basically the same as Wikipedia’s. An encyclopedia with biases. In Grokipedia there are signs that the theoretical neutrality and objectivity that should be fundamental pillars of such a project are faltering. As indicated in Wiredthere are worrying examples such as the one that talks about the slavery of African Americans in the US in which they talk about “ideological justifications.” In an entry about “gay porn“false information is shown indicating that the proliferation of these contents fueled the AIDS epidemic in the 1980s. In the entry on the genre, Grokipedia indicates that “gender refers to the binary classification of humans as males or females based on biological sex.” Wikipedia start entry stating that “Gender is the range of social, psychological, cultural and behavioral aspects of being a man (or boy) or woman (or girl), or a third gender.” In the image and likeness of Elon Musk. and the article about Elon Musk It contains 11,000 words and 300 citations/references compared to the 8,000 and 523 of its Wikipedia version. In both encyclopedias there are curiosities about that article, and for example in Wikipedia there is a section dedicated to Musk’s controversial greeting which is not on Grokipedia. And on the opposite side, Grokipedia does have mention of the “fart guy” controversy which is not available on Wikipedia. This is just the beginning. This version “0.1” of Grokipedia contains 885,000 articles, while Wikipedia has more than 8 million entries. In 2017 Elon Musk posted a tweet in which he praised the work of Wikipedia, but over time that perception changed, probably due to the comments included in the entry about him on Wikipedia. This year tweeted the message “Stop financially supporting Wikipedia until balance is restored!” The danger. Although Elon Musk assures that Grokipedia is open source and anyone can use it for free, it remains to be seen the ability that its users will have to edit articles created by AI. The risk is that this project poses a new attempt to control the conversation, and as he says entrepreneur Gary Marcus, “whoever writes the encyclopedia controls the narrative.” Jimmy Wales warns. The creator of Wikipedia, Jimmy Wales, indicated in an interview in The Washington Post a few days ago that he was curious to know what Grokipedia would end up being, but that he did not have too many expectations about the result. For him, AI language models “are simply not good enough to write encyclopedia articles. There will be a lot of errors.” Lauren Dickinson, spokesperson for the Wikimedia Foundation, explained in The Verge how “Wikipedia knowledge is and always will be human.” Problems for the free and human-created encyclopedia. Even so, Wikipedia is threatened by AI. Not only because this legendary online encyclopedia has been the great manual for training AI, but because it is suffering a traffic crisis. The xAI project is the latest attack on that source of knowledge and information, which, from being under control and editing completely carried out by human beings, now cedes those editing and writing tasks to xAI’s AI model, Grok.
