works

This is how this silent (and advanced) system called XProtect works

by

Malware is not an exclusive threat to PCs. Macs can also become infected. For this reason, there are different third-party security solutions, such as Bitdefender, Intego, Malwarebytes or Avast, among others. What not many people know is that Apple computers have, for more than a decade, had a integrated antivirus called XProtect. XProtect It has been running silently in the background since it landed on Mac OS Unlike Windows Defender, there are no icons in the menu bar, nor do we have an application to manually perform system scans. How does XProtect work on macOS? The Apple ecosystem has a variety of protection measures, and XProtect is one of them. If we focus on macOS, the Mac operating system, Apple tries to avoid the malware from the App Store. The company reviews the applications so that no malicious software lives in its store, but let’s be honest, we don’t always use the App Store. Computers have always given us the freedom to install any compatible external software. To address the issue of external threats, Apple has a certification mechanism, where developers who do not use the App Store to distribute their applications can obtain a trusted certificate for macOS. Apple does not take this task lightly. Scans the applications and grants the certificate only when it cannot find known malware. Once this instance is passed, developers receive a certificate that they can attach to their application so that the target system can verify it, even when it does not have an Internet connection. At this point we find another of the protection measures. This is Gatekeeper, which looks for that certificate in the application that the user is trying to open or install. If the program does not have the corresponding certificate, the system warns users that they are trying to use software that cannot be verified. Since not all developers go through the certification processwe can ignore that message to use the application in question. Sometimes we will have to allow the installation of applications from the App Store and well-known developers from System settings > Privacy and security > Security > Allow applications from… XProtect is responsible for preventing the execution of malicious software. If for any reason the protection measures mentioned above have been violated, XProtect is responsible for preventing the execution of malicious software for the first time or detecting malware that has been executed on the computer. This integrated antivirus uses YARA signatures that are automatically updated periodically. XProtect comes into action at three key moments: when opening an application for the first time, when modifying an application in the file system, and when updating security signatures. If you detect known malware, blocks it immediatelynotifies the user and offers the option to send the software in question to the recycle bin. XProtect’s scope does not end there. Apple has improved the system to address problems that certain infections can cause. Once malicious software is removed, the built-in antivirus continues to scan for threats using a behavioral analysis engine. Of course, it does not have the ability to restart the computer. How do you update macOS built-in antivirus? XProtect updates automatically. However, you can buy if the system is installing the updates automatically. To do this, click the apple icon in the toolbar and then go to System settings > Software Update. Then tap the information icon under Security Answers. In the Automatic Updates category make sure the Install security responses and system files switch is turned on. So am I completely sure now? Although macOS has a solid security system, it is important to clarify that no system is 100% secure. In the world of cybersecurity it is often said that what is sought is to increase the level of difficulty for cybercriminals. And we achieve this in many ways. Integrated system tools are only part of this. The security features of the applications themselves, our security practices and, if necessary, third-party security tools also come into play. The level of difficulty varies according to the needs of each user. For example, for a long time iPhones and Macs can activate Isolation Mode. This is an extreme solution, but it is a good example of what it means to put higher barriers. This mode limits the functionality of applications, web pages, and certain system features. As a result, we obtain a more protected system, but much less useful than in its standard configuration.

what it is, how it works and is used, how to hire it and how much it costs

Let’s tell you what is the OpenAI Operatora new launch from the company responsible for ChatGPT with which they are betting on AI agents. But being a quite different product and with other purposes, it is perhaps a little more complicated to understand and more confusing. Therefore, we are going to try to explain everything to you in a simple way. We will start by explaining what AI agents are and what Operator is. Then we will tell you how it works, and we will finish by talking to you about how to access it and the price it costs. What are AI agents This is what Operator looks like in action Operator is an Artificial Intelligence agent created by OpenAI. AI agents are automations that perform actions for you on the computersuch as in the browser. The idea is to streamline processes in which you have to perform several different tasks, and allow the agent to do it for you. It’s going to be something like a virtual secretary. For example, think that you want to go on a trip to a city, and that you have two or three destinations in mind. Currently, what you do is look for hotel options in the cities, look at the weather information, and even see what events that interest you are in these cities to make the decision, and then you book and pay. The agents’ idea is that do all these processes for you. For example, you just write to the agent on your computer (or tell him with your voice) that you want to leave on certain days and that you are thinking about these two or three destinations. Then, the computer is in charge of checking the weather, seeing interesting events, offering you hotel options and collecting and giving you all the options so that you only have to choose one and confirm the payment. However, this is the ultimate goal of the operators. Currently, the options that are being launched are much simpler, although they continue with the objective of being able to do as many things for you. In a few years, this could be a reality. What is Operator? Operator is an AI agent created by OpenAI. It is currently in the development phase, although there are already some users who can start using it. This is an agent that can navigate the web to perform tasks for us. Operator will have the ability to use its own browser to browse the web, and interact with a page writing and clicking and scrolling to find information and perform tasks for us. In this way, what OpenAI wants is for you to be able to tell Operator something like “Reserve me a table for two at Beretta for 7 p.m.”, and for this agent to take care of doing it for you Opening a reservation website, search for the venue, select the date and time, and make the reservation for yourself. If a problem arises such as there is no free place where you want to go, or if some sensitive information about you is required, then it will ask you to intervene. Come on, the idea is not to do things crazy, but to If he can’t do something, he’ll ask you. so you can decide what to do. Following the reservation example, this allows you to choose another date or time, or for you to write your payment method so that the operator does not use your card on its own. But it can also ask you for confirmation of actions or helpthe first in payments and when making final decisions, and the second in other obstacles such as a CAPTCHA or having to write username and password. You will also be able to create custom tasks, configure specific instructions and preferences for automate tasks you do frequently. For example, if every month you make a specific purchase in an online supermarket or do some periodic online action, you can configure this so that Operator does it on its own from time to time. At the moment Operator has only been announced and released to a small group of people. It is in the investigation phasewhich means that they will use the data and feedback from the first users to start fine-tuning it and improving its operation. This also means that at the moment it is not very reliable, and that it can make mistakes. How Operator works Operator uses an own artificial intelligence model. Is called Computer-Using Agent (CUA)and is based on GPT-40. This model is able to “see” what is happening in the browser by taking screenshots, and then allows you to use typical controls such as the cursor or mouse to navigate and take actions on the web page you go to. This model is capable of analyzing and understanding each pixel of the screenshots taken on a website, and thus knowing identify objects on screentext and images. Once it analyzes the content of the website, it does a kind of internal “reasoning” and follows a line of “thought” to carry out the actions. Of course, it is also adapting taking into account past actions. To carry out the tasks, Operator uses an internal browserso you don’t have to install anything. This browser works remotely from OpenAI’s servers, and both your data, what you ask of it, and the captures of the websites end up stored on the company’s servers. This means that, as happens in ChatGPT and almost all AI models that do not work locally on a computer, the company owns the data. OpenAI will then use this data to detect fraudulent activity and to train and improve the model. In any case, you can deactivate this collection from the settings, or decide how long the data is stored. How much does Operator cost? Operator will be included in ChatGPT Pro subscriptionwhich is the one that has a price of 200 dollars a month. Therefore, you cannot hire … Read more

Operator works differently (and better) to other agents who see our screen. Your secret: Cu

by

We already have OpenAi’s agent. It is called Operatorand it is a system capable of seeing our screen and performing actions autonomously in the browser from our requests. It is something we had already seen with ‘Computer Use’ from Anthropic either Deepmind Marinerbut here the company led by Sam Altman has its own special ingredient. Computer-Useing Agent (Cua). Operator uses a model called Computer-Useing Agent (CUA) that is based on GPT-4O. CUA interprets screenshots and interacts with websites through the typical browser controls, such as a cursor or a mouse. How Cua works. As they explain In Openai’s documentationthis system processes those “raw pixels” of the captures that you make and use a mouse and a virtual keyboard to complete its actions. Once you have the screenshot, “reason” and follow a “thought” line in which the past actions take into account. Promising performance. There are several benchmarks since they allow to evaluate the ability of these agricultural models. According to them tests performed internally In Openai, CUA achieves a 38.1% performance in OSWORLD (Use of a computer in general) against platforms such as Anthropic, which achieves 22%. Humans, yes, achieve 72.4% on average, which makes it clear that these systems still have a lot of improvement margin. In the use of the browser, the Benchmarks Webarena and Webvoyager also allow Operator to score very high: 58.1% and 87% respectively, compared to 36.2% and 56% of their competitors. What about those catches that I collect operator. Operator continuously performs screenshots to “see” the browser interface with which he interacts. That browser does not run on our PC, but in a remote browser on OpenAI servers. User data, including these catches, are used according to OpenAI’s privacy policy. This is: they can be used to detect fraudulent activities and to improve the service. That implies that our data can be used to train and improve the model, although We can deactivate that option In operator settings. The user, yes, has the capacity for how long this data is stored in Operator. By default these data are saved until the user decides to delete them. An agent who asks for help (and confirmation) when he needs them. As we have seen in other agents such as ‘Computer Use’ of Anthropic, Operator is an agent who does not act crazy. If you meet an obstacle – like a captcha code or the request to introduce user and password on a website – you will ask that the user take control, and will also ask for the final user confirmation if for example we have to validate a reservation or purchase of a product that has sought Operator. The operator user can also take control at all times. This is how it works. Source: OpenAi Do not release the steering wheel. This reminds us of assisted driving systems such as Tesla FSD. It is true that it is able to take us from one place to another once we introduce the destination address, but it is important to continue paying attention and have our hands in the steering wheel in case they occur unforeseen. With Operator and the rest of this type agents something similar happens. There are things that cannot be done. At the moment Operator cannot complete specialized tasks such as managing complex calendar systems or interacting with very personalized or non -standard websites. You will also refuse to do some tasks with high risk of provoking damages. For example, send emails, make electronic transactions or delete calendar events. Its benefits and capabilities will increase, without a doubt, but they will gradually do so and always guaranteeing that the possibility of error is the least possible.

Blanca Suárez uses Úrsula Corberó’s anti-aging treatment and works on the area of ​​the face that ages the most at home

Blanca Suarezwho we will be able to see again on the big screen this spring with the premiere of The trace of evila film directed by Manuel Ríos San Martín, has always defended natural and unfiltered beauty. In fact, he posts frequently on his social networks. photos without makeup in which we see her boasting a radiant face. © Getty Images The actress take good care of your skin and shares some of her beauty secrets with her virtual followers. He especially likes masksyes. Combine its use at home with cabin beauty treatments to show off a face that is always young and free of imperfections. © ursulolita © blanca_suarez Blanca Suárez and Úrsula Corberó connected by the treatment that is in fashion “Living exomada”Blanca Suárez wrote on social networks after having acquired the doctor Lidia Maroñas, founder and medical director of Clínica Oneskinmed (located in the heart of the Chamberí neighborhood, in Madrid) a exosome treatment. Úrsula Corberó, like Kim Kardashian, Kourtney, Sofía Vergara and Sarah Hyland, also uses this to show off radiant skin. This regenerative therapy, based on the action of stem cells, improves skin in an incredible way: unifies spots, illuminates, combats expression wrinkles and firmness. This is explained by Elizabeth Álvarez, founder of Inout, the beauty center that Corberó chooses, precisely. Elizabeth tells us that It has been investigated since the 80s of the last century. at a regenerative level, but it is now when it is incorporated into skin aging procedures. Exosomes contain genetic material, proteins and growth factors, among other substances. They are capable of stimulate collagen and elastinhydrate, repair DNA damage, protect from oxidative stress, improve skin texture, reduce spots and treat dermatitis or psoriasis. Next to nothing! In Spain, to date, Only those of plant origin and topical origin are authorizedalthough it is expected that they can be injected in the near future. At the moment, on a topical level, they leave wonderful results and you just have to see it on the faces of Úrsula and Blanca. The second, furthermore, work on an important area of ​​the face at home that It is worth taking care of to show off an always young face.. © blanca_suarez The area of ​​the face that, like Blanca Suárez, you should work on Although also resort to clay and gel masksthe Madrid have recently worn a face veil that specifically affects the so-called nasolabial fold. We call the nasolabial fold the line that extends across the cheekbones, cheeks and around the mouth; a line that becomes accentuated with the passage of time. © blanca_suarez © blanca_suarez Dr. Carlos Gómez, a specialist in aesthetic medicine, assures that “we are used to referring to the nasolabial fold in general, but this unsightly problem is the sum of the appearance of three very marked lines: the nasolacrimal, nasolabial and labiomental or mental lines. puppet and that they are a product of facial sagging process that happens over the years, as well as the bone and fat loss in the cheekbone area“. Therefore, although Using the so-called nasolabial patches like those from Blanca Suárez can help you a lot, it is essential to also work the cheekbones. In this sense, the doctor is clear: “Anatomically, The nasolabial fold is formed as a result of loss of bone and fat structure of the entire cheekbone regiontherefore, returning the lost volume to that structure and stimulating again the collagen and elastin formation allows us to reverse the nasolabial fold from the origin and the rest signs of aging tensing upwards”. © Getty Images How can we prevent it from being marked more? To work the cheekbones, we can not only resort to hyaluronic acid in aesthetic medicine, allowing ourselves to be advised by professionals, but we can also use other methods such as yoga and facial gymnastics. The facial gym firm Work Your Face offers its own method based on manual massages, called Workouts, aimed at train facial muscles in the same way that pursues fitness body, working each muscle correctly and in depth until it is strengthened. A few more minutes of reinforcement can be added to these workouts depending on each case, either due to skin needs or to work on specific areas such as the neck, shoulders or neckline, or the nasolabial fold. © Getty Images The best solution and some recommended products It must be taken into account that, as stated by Dr. Guillermo Llopis, from Clínica Ferraro, “there is no conclusive scientific evidence that supports the benefits of facial yoga to define the face.” Yes they can help us tone certain muscles But we will perceive the real difference when we work on all levels: bone, muscle and skin. “As There are many factors that influence agingwe work on different levels, both the bone, the superficial fatty compartments and the outermost part of the skin,” explains Dr. Llopis. As always, the best thing is a 360 approach and keep in mind that the foundation on which doctors and experts work is laid by oneself. That is why physical exercise to maintain good bone and muscle health, as well as diet, home treatments and a good self-care routine, are crucial. According to pharmacist Marta Munar, from G19, active ingredients such as retinol, glycolic acid or peptides are capable of inducing the synthesis of collagen and elastin and to combat the results of its degradation. Others like him hyaluronic acid They are capable of retaining water to fill wrinkles and reduce expression lines. He also tells us that the vitamin C It acts preventively due to its antioxidant action that stops the degradation of the two supporting proteins. In line with this, we show you some products that can help you.

OpenAI presented ChatGPT in 2022. In 2023 it arrived GPT-4 together with the innovator ‘Her’ style voice mode. In 2024 the reasoning model debuted o1. And 2025? The AI ​​company just announced Operatora product that promises to become one of the great protagonists of the year. Sam Altman and his team have presented live How does this tool work that puts people at the center of the scene? AI agents. Currently, as we’ll see, it can perform some actions in the browser, although the ambition is that, over time, it can handle more sophisticated tasks. This is what Operator looks like in action We are witnessing an initial launch. Operator is still in the research phase, but OpenAI has made a publicly available preliminary version which can be accessed from operator.chatgpt.com. The limitation? That not everyone will be able to have access to it. At the moment, it is only available for ChatGPT Pro users, the level of 200 dollars per month. The company has also noted that access to its latest product is limited to the United States. He has said that “it will take a while” to reach Europe, and that it will be available to more users “in the coming months.” The staggered launch likely responds to regulatory issues, as we have seen in the past with products that landed in the US market first.

an electrical grid that works 24/7 with solar energy

by

We tend to assume that solar energy is intermittent, but there is nothing that petrodollars can’t solve. And Abu Dhabi is precisely the first city in the world to announce a large-scale solar plant designed to operate 24 hours a day, 7 days a week. The news. The pulse of the United Arab Emirates does not tremble investing what is harvested with its fossil fuels in renewable projects that will one day replace them. Its capital, Abu Dhabi, has just signed for 6 billion dollars the installation of a photovoltaic plant on a public service scale with a particularity. According to Masdar, the developer, it will be the first solar plant designed to supply clean energy 24/7 thanks to the combination of the Emirati sun, millions of solar panels and a huge storage system. The details. The huge project, participated by the state company EWEC (Emirates Water and Electricity Company), will combine a 5.2 GW photovoltaic plant with a 19 GWh battery storage system. Once connected, the plant will not only power millions of homes, but will be responsible for up to 1 GW of the grid’s base load, the minimum power required by the electrical grid that is traditionally covered by more stable thermal sources, such as coal. and gas. Alliance with China. As is happening in neighboring Saudi Arabia, the Emirates is strengthening ties with Chinese companies for this renewable drive. JA Solar and Jinko Solar They will supply 2.6 GW of solar panels each based on TopCon technology, which has higher efficiency and lower degradation rate. For its part, CATL will supply the batteries directly integrated into its HAVE storage systemwhich promises zero degradation in five years and a capacity of 6.25 MWh per container. POWERCHINA and the Indian multinational Larsen & Toubro will be in charge of the design and construction of the plant, which will generate 10,000 jobs. Green Emirates. The Abu Dhabi project, whose roadmap marks the start of operations in 2027, is framed in a long-term plan of the United Arab Emirates: the Energy Strategy 2050. The country hosted the COP28 summit, in which United Nations countries emphasized the urgency of installing more sustainable energy solutions. Sultan al Jaber, who chaired the summit, is also Minister of Industry and Advanced Technology of the United Arab Emirates and president of Masdar, promoter of the solar plant. “For the first time, we will transform renewable energy into 1GW of reliable baseload power, at unprecedented scale,” highlighted al Jaber in a statement.

What is Perplexity, how it works and what the Pro version of this artificial intelligence search engine is like

by

Let’s explain to you what is Perplexitythe popular conversational artificial intelligence search engine. It is a tool that seeks to revolutionize the way you find content on the Internet, although currently chatbots such as ChatGPT, Copilot either Gemini They are also capable of using AI for these searches, although they do not specialize in it. We are going to start the article by briefly explaining what exactly Perplexity is and its internal workings, as well as the difference compared to conventional search engines. Then, we will tell you in a simple way what the external functioning of the search engine is like, and the functions they have. We will finish by talking to you about its paid version. What is Perplexity Perplexity is a conversational search engine that works through artificial intelligence. seeks to offer an easier to use alternative to Googleand in which you will not have to go in and out of links to find the answers you are looking for. The main difference with conversational search engines is the way you interact with it. While with Google or Bing you have to type keywords to find the content, with Perplexity you have to ask a question with natural languageand the AI ​​will understand what you are trying to find, and offer you the answer. It is able to do this because inside the search engine we have an artificial intelligence system that, like ChatGPT or others, has been trained to analyze your text and understand natural language with whom you are asking something. With this, when you ask it a question it extracts the meaning of the words and how they work together, and allows more precise searches. On Google, when you want to write more specific things and ask very long questions, the results may be very bad because it tries to find content with all the words. Perplexity understands the concept of what you want to findand with that performs more precise searches. Furthermore, this search engine is respectful of its sources. Unlike ChatGPT, Copilot or Gemini, the web pages from which the information was obtained do not seem hidden. Instead, it shows them at the top, and you can click to go directly to specific pages or click on the box where they all are to display them as a list. In this way, Perplexity also allows you verify information more easily. Artificial intelligence systems sometimes make mistakes or hallucinations in their response, and having sources of information nearby will make it easier to verify that what they say is true. How Perplexity works Perplexity’s home page is similar to other artificial intelligence search engines and chats. Upon entering perplexity.aiyou will have a search field where you can write what you want to find. Below you will also have some suggestions for questions in case you don’t know how to start using it. Below the search field you have several options. With the Focus option you can choose where to search of what you want to find. For example, in addition to searching the web, you can search in academic documents, or social networks, you can search videosand even receive better answers to writing or mathematical problems. You will also have options to upload a PDF file and perform internal searches, or to activate Pro mode, which is the paid version of Perplexity. For these two functions you will first have to create an account, although not necessary for simple searcheswhich you can do without a user account. When you ask a question, Perplexity will compose an answer based on the information it has found on the Internet. But on top of this answer you have a Sources section with the pages Where did you get the information from? On the right, you can also display images or videos, to see those that are related to the search you have performed. In the section of Sources you have four paintings. The first three are links that take you directly to the pages from which the most information has been obtained, and the fourth allows you open a list with all sources that you have used and the articles from which the information with which you have generated the response came. This way, you can enter the one you want just as you do with Google. For some questions you will be answered with graphics or images, especially for quick ones that you can ask, such as what the weather is like today or tomorrow in a certain city. Perplexity vs Perplexity Pro Perplexity has a paid version called Perplexity Pro. In exchange for a monthly payment of 20 euros, you will have advanced functions, such as choose the AI ​​model you want to usebeing able to choose, in addition to their own, other much more famous ones. This is the table with the differences: Perplexity perplexity pro queries Fast and unlimited Fast and unlimited Pro consultations 3 a day 300+ a day AI models Standard Perplexity Standard Perplexity GPT-4o Claude-3 Sonar Large (Llama 3.3) and more… Profile You can create one to customize responses, but it’s optional. You need to create one before subscribing to the pro. Upload and analyze files Only with account Limited Unlimited View responses No Yes, using Playground AI, DALL-E, SDXL and more API Credits No 5$/month As you can see, the main difference is that you can make daily Pro queries with which to obtain better results, and you can compose the answers with other artificial intelligence models like GPT-4o and others. Thus, you do not depend on the advances of the Perplexity model, and you can use other more advanced ones. There are also advantages when it comes to uploading files and analyzing them, which is an unlimited function, and composing images to visualize the responses, something that in the Pro version you can do… and using different image-generating AI models.
