How to create a presentation in Canva with artificial intelligence

by

Let’s explain How to create a presentation with Canva using artificial intelligence. Canva is one of the best known online services when creating presentations and all kinds of designs, and in recent months they have been adding functions and automatisms. Let’s explain two ways to make the presentation In Canva with Ia. In the first place we will tell you how to make each vignette from scratch, something more laborious but that you can customize to your liking. And then, we will tell you how to do it with templates. In both cases you will have artificial intelligence options. VIÑETA TO VIÑETA FROM ZERO When you enter Canva.comon the main screen you have a text box where you are asked what you want to design. In this picture Choose the option of Canva Ia to activate the artificial intelligence of the service. Then, choose the option to create an image, and choose the style and proportion with the way you want to make the vignettes of your presentation. Now, you just have to Describe the vignette you want to create With artificial intelligence, describing what you want it to appear, style, and even colors. It is important that you try that each vignette always has the same proportion of size, and also the same style so that everything is more cohesive. Every time you write the Prompt Four different bullets will be generated. You can try and repeat the process until one is created to your liking, changing the description and elements. When you finally have one you want to use, click on the button Edit That will appear in it. Once you enter the vignette editing options, you will be able to Use several artificial intelligence tools. Each of the elements that you can add has an IA option, even to add text, where you will be able to generate it from certain concepts. When editing the image itself, you can choose an area or a specific element of it and edit it with Ia. You have magic draft options to eliminate elements, or magical edition to change one thing that appears for another. Although yes, Many options are paymentand you will need to subscribe to use them. You can also add imageswhich can be complete with their bottom or simple with transparent background. I recommend that you explore all the options to leave each of the vignettes of your presentation to your liking, and when you finish one doing the next to complete what you want. From a template When you enter the Canva website, in the text box you can also click on Templates. Then, in this text box write the term “presentation.” You can accompany it for some other words that define the theme, colors, tone or type of design you want. When you click on each of the results, you can see the vignettes that make up each template. When you see one that you like click on Customize templateand will take you to the editor. Once you enter the editor of Canva, You can use all artificial intelligence toolsincluding those mentioned in the previous point, to modify each template file and leave it to your liking. You will not have so much control, but if you find a design that you like it will be faster. In Xataka Basics | 22 useful and not so well -known free artificial intelligence tools

When the bosses already value at the same time they do not work in your free time

More and more companies recognize the importance of their employees Disconnect from work to improve your well -being and Avoid exhaustion. After all, it suits them since that way Improve productivity. However, a New study It has confirmed the existence of a significant contradiction: although managers value their employees to take breaks and maintain a good balance between working and personal life, they usually penalize those who make use of those limits. The detachment paradox. The study carried out by researchers from the University of Science and Technology of Hong Kong and the Spanish IE Business Schoolanalyzed how managers perceive employees disconnect of work in your free time. “We only analyzed what happens when the worker should not work, such as the afternoons, on weekends and vacations,” said Elisa Solinas, co -author of the study. OK To what is published in Hardvard Business Reviewthe experiment had 7,800 participants, in which managers evaluated fictional employees who in a version took measures to disconnect from work and in another not. The results showed that, in their reports, managers recognized that those who disconnected from work during the weekend, returned with more energy and better performance. However, in the evaluations, they constantly described them as less compromised, even if they were more productive than those that did not disconnect. Even if you are the best, do not rest. The data suggest that the feeling of reproach of managers towards employees persisted even when the employee was a direct subordinate of the manager, when the employee who was disconnected was objectively better in his work and even when he disconnected for a justified reason as take care of a relative. As they stressed in HBR, managers tend to identify Availability with effort and commitment. “Our studies show that the commitment is valued almost more than productivity. In short, we seek to perceive that a worker is really committed, and that is what, in fact, we reward more than productivity,” declaredBuechel a Fortune If you take care of yourself, you don’t ascend. The experiment revealed that, in addition, 62% of managers considered that those employees who put limits between working time and staff were less likely to be promoted, despite recognizing that their productivity could be greater. A bias that too It was given on teleworking. As Eva Buechel explained, co -author of the study: “The same people who said that workers were going to be more productive also said they were going to be less promotable.” This bias reflects that, although the disconnection and rest improve health and employee performance can negatively affect the perception of commitment and professional opportunities since employees who respond outside your working hours or that their vacations skip are seen as people who strive more. The cost of not disconnecting. The pressure to always be available generates negative consequences. According to data from A studyMade by the Glassdoor Employment Portal, exhaustion reports increased by 32% year -on -year during the first quarter of 2025. Employees who claimed to feel exhausted have shot themselves above 50% if it was counted since 2019. “Even if a satisfied or high -performance employee can support a greater workload without impact on its productivity or in its satisfaction during a short period, that does not necessarily mean that it can do it indefinitely,” wrote Daniel Zhao, author of the Glassdoor report. Benefits of taking a break. A meta -analysisLed by Ryan Grant, a PhD student in Psychology at the University of Georgia, he found that the revitalizing effects during free time are actually 85% greater than what was suggested in different studies, and their benefits can be extended up to 43 days after the holidays. Grant points out that the disconnection capacity “was the only recovery activity that had a strong positive association with well -being, both during the holidays. This suggests that the more you disconnect yourself psychologically from work during your break, the better your vacation will be your vacation and the greater your benefits for well -being later.” The scientific evidence It corroborates Grant’s conclusions on the benefits in the mental health of employees who separate work time and leisure time. Disconnected by law. Countries like Spain and Australia have created a legal framework to guarantee the Right to digital disconnection Out of working hours. The regulations not only exempt employees from responding to any message or call of their work during their rest time, but penalize companies that carry out these practices. What the legislation cannot regulate is the perception that managers have of those workers who comply with the work schedule that appears in their contract.

I have to prepare the suitcase for this vacation. I do not leave the house without swimsuits, but neither without a VPN on the mobile

by

After a wait that sometimes has become too long, the time has come that many expected: summer holidays. These are dates that many take advantage of some escape, one that almost always leads us to accommodations such as hotels that have Wi -Fi networks for your guests. These can come great, but are they entirely safe? These and others public Wi -Fi networks They are perfect in those moments in which we do not have coverage or in which we do not want to spend our data, but they are still networks that we know very little. Luckily, there is a very simple way to protect ourselves when we connect to them: Use a VPN. This surfshark is one of the cheapest we can findsince just goes out for 1.99 euros a month. Surfshark Starter Subscription – Monthly * Some price may have changed from the last review More internet security no matter how little every month It is no secret that we can find several on the Internet Free VPNwhich do not work badly and can get us out of trouble in case we have none. The problem is that the service offered by these is limited and the connection speed is, in most cases, too slow. Does not suffer this happens to get a payment VPN, but we don’t have to spend a fortune if we bet on one like Surfshark. It is one of those things that it does not occupy just site and that is always worth installed, both on the mobile and in a laptop or on a tablet. In fact, with surfshark we can install the VPN In how many devices we want without any limit. With this, what we will have is greater privacy and greater protection of our information on the Internet, something ideal in unknown networks. In the case of Surfshark, in addition, its VPN is included in its Starter Plan. This, which is the most economical of those you have, includes another very useful tool called ALTERNATIVE ID. This serves to generate a series of fictional data that we can use to register in some pages that we do not consider safely or where we simply do not want to enter our real data. The Starter Plan is priced at 1.99 euros per month, so if we make numbers, two years of the service will be released for a total of 53.73 euros, since in addition We will receive 3 months extra service (that is, we will have 27 months). Here we are facing a very important discount, since its discount price amounts to 417.15 euros. Some of the links of this article are affiliated and can report a benefit to Xataka.

Dreame just presented your new series of aspiring robots and the first member of the same. With the Aqua Series, the company wants to give a twist to the scarf and its new Aqua10 Ultra Roller It is the best proof of this. Because yes, this robot aspires and passes the mop, nothing new, but it does so in a way that we had not seen to date and that promises interesting changes: with a rotating mop that is cleaned in real time. Dreame’s thesis is simple. When An aspiring robot passes the mopadirt stays in it and walks throughout the house for a simple reason: the mop is the same. If the robot passes through the bathroom or kitchen, where there may be dirt or fat, the cleaning will be harmed in the rest of the rooms and we can face cross contamination. This there are ways to avoid it in some high -end models (programming a return to the base and cleaning of the mopa after finishing x rooms or a specific room), but makes cleaning time increase a lot. Dreame’s proposal goes one step further and is, as little, curious. Scheme of the roller -shaped mopa of Dreame Aqua10 Ultra Roller Complete | Image: Xataka A MOP that revolves … Instead of a simple mop or a circular mop as we have seen in other models, the Dreame Aqua10 Ultra Roller Complete Mapa is rolled up. While the robot passes the mopa, this tour of 100 revolutions per minute and is cleaned in real time with new water thanks to a system of 12 spray nozzles. Simultaneously, a flush eliminates dirty water, which is stored in a separate tank inside the robot itself. … what is combed …. Another problem that conventional mounts have is that they are caked with use, especially if there is a lot of dirt on the ground. To avoid this, Dreame has implemented a system called Fluffroll that, basically, is a kind of roller/comb that rotates at 1,000 rpm in the direction of the mopa. This comb, they affirm from DREame, maintains the spongy mop and with the loose fibers, something that, on paper, should get cleaning uniform throughout the process. Bottom of the aspiring robot. Here we can see the size of the roller (which can be moved to the side to reach the edges) and the anti -edge combs | Image: DREame … that hides … Dreame has not forgotten carpet users. It is common for high -end robots to be able to raise the mopa and prevent contacing the carpets, but Dreame has taken another step. The mop does not rise, but has an automatic closure, a kind of barrier, which is automatically activated and prevents the mop from touching carpets or dripping. … And that is cleaned with heat. When the cleaning is over, the robot will return to the base, it will be emptied and the cleaning of the mop will begin. As? With hot water at 100ºC. According to me, this system should be able to dissolve fats, discourage dry dirt and eliminate odors, bacteria, etc. When it passes through a carpet, the robot itself covers the mop to prevent dripping | Image: DREame What else? Although the novelties of the mop are, without a doubt, the most striking, the Dreame Aqua10 Ultra Roller Complete is stored other tricks under the sleeve. For example, it has retractable robotic legs that allow you to overcome small steps of up to six centimeters. It also has two HD cameras with NVIDIA ISAAC SIM and Reinforcement learningan upper retractable LDS sensor, 30,000 pa for suction power and, of course, the roller moves to the side to clean the edges and corners well. On the basis. The base not only works as a cargo station, but also cleanses the robot and keeps it ready. In that sense, it has a clean and dirty water deposit and solid tank. Like other company models, it is possible to connect it to a water outlet and exit at home so that maintenance is more automatic. The base can be used or can connect to a water outlet with an accessory | Image: DREame Price and availability. As explained by Dreame, the device will be put on sale from the fourth quarter of 2025. Details on the price will be confirmed later. We will update this article as soon as we have more information.

Malaga will not be able to fulfill his dream of hosting the National Cybersecurity Center. A controversy that has sat as a jug of cold water to the Junta de Andalucía, which applied the coastal city as its best alternative to host this center. The problem? There was no center to host, as the government has clarified. The candidates. Just Malaga and León They had formalized their candidacies to house the coveted institution, with the respective support of its autonomic governments. Malaga sounded with special force, in his efforts to continue adding victories in his attempt to turn the city into One of the country’s main technological hubs. Neither one, nor another. Neither cities will host the headquarters of the future National Cybersecurity Center. The reason is very simple: No city in Spain will host this center… because this will not have any physical space. The Government of Spain has clarified through the Ministry for Digital Transformation and the Public Function that this technological body will not be “an agency or any newly created institution that requires physical location.” One more administrative department. The Junta de Andalucía ensures that there was a “technical memory” prepared by the central administration, with the forecast of dozens of jobs, details on the rental costs and characteristics of the building. Something that The government itself advanced in Aprilwithout formalizing it documentary, but in statements by Óscar López, Ministry of Digital Transformation. Malaga’s candidacy managed to agree on the entire Andalusian Parliament: PP, PSOE, Vox, by Andalusia and Adelante Andalucía approved a No law proposition To contemplate the city as a candidate. A Spanish. In short, the confusion between the communities of Andalusia, Castilla y León and the Government of Spain attend to: Lack of clear communication by the government In the early phases of project development. Lack of clear communication from the communities by presenting a candidacy for an organism that had not confirmed creation of independent physical headquarters. Lowering expectations. Óscar López himself assured that the creation of the new agency only responded to the fulfillment of the new European Cybersecurity Law. One that requires that all the coordination of centers linked to this field be mediated by national institutions. The new National Cybersecurity Center, attached to the General Secretariat of Presidency of the Government, continues to show doubts about its strategic functioning. The draft defines it as a “coordination organ”, but its powers are still without being clear. How is the patio. Currently, Spain has its cybersecurity structure well defined. INCIBE-CERT National Cryptological Center Joint cyberspace command The new center will be nothing more than an administration attached to the DSN (Department of National Security), without its own entity or its own legal personality. The controversy arrives at one of the most critical moments in Spanish cybersecurity, With domain. It is in full crisis and Uploaded to the Podium of Cybeards.

How can we avoid its consequences

Surely we have heard dozens of times of acid rain without knowing exactly what it is. It is also possible that we have a cartoon image of this very real phenomenon, a rain that corrodes and destroys everything it touches. There is something true in this but, of course, reality is a bit more complex. First of all we must answer an obvious question: What is acid rain. We refer to acid rain to a rain that drags acid components. These components can of different types, for example nitric acid or sulfuric acid, so there is no “standard” composition of acid rain. Acid rain does not have to be strictly, rain. Other similar events, such as fog or hail, can also make the acidic compounds of the atmosphere intermingle with water and give rise to “acid rainfall.” In a way we can see acid rain as a variety of phenomena with a common denominator in these Acid components. The result is more acidic than normal rainfall: if the rain usually has a pH of 5.6, acid rain tends to have values pH between 4.2 and 4.4. How acid rain occurs Acid rain usually begins with atmospheric emissions of compounds such as sulfur dioxide (SO2) or some nitrogen oxide (NOX). These compounds can be issued by the industry or means of transport (although they can also arise naturally) and dragged from industrial and urban areas to distant areas. In the atmosphere, these compounds can end up mixing with oxygen, water, and other components, unleashing chemical reactions that give rise to the formation of sulfuric acid and nitric acid. These acids are later captured by water itself, forming acid rain. They can also end up precipitating themselves on land, vegetation or terrestrial waters, in what we call the phenomenon of dry deposition. How it affects the environment According to Explains the United States Environmental Protection Agency (EPA), the effects of acid rain can be seen more clearly in aquatic environments. Although the increase in water acidity can be harmful to many species (especially young), the main risk is indirect. When acid rain falls on the ground, it can interact with clay particles in these and Extract aluminum They could contain. Due to runoff, part of this aluminum ends in rivers and lakes, affecting aquatic life. This aluminum can also be absorbed by plants, which implies that acid rain can also affect plants, not corroding them as we can imagine but intoxicating them from the ground. It can also make the ground lose nutrients that plants need. Different species may have different levels of tolerance regarding these impacts, however we must take into account that ecosystems are complex systems where the loss of a piece can affect many others. EPA puts a Example with frogs: While these can endure a pH of up to 4, some of the insects they feed cannot survive in waters with a pH below 5.5. How it affects people Acid rain also generates impacts on people. Again, we can rule out the idea of direct damage as skin damage derived from contact with this rain. “Walking in acid rain, or even swimming in a lake affected by acid rain, is not more dangerous for humans than walking in normal rain or swimming in non-acid lakes,” Explain EPA itself. That does not mean that acid rain does not affect us, only that it does so indirectly. Acid rain can also expose us to heavy metals. Studies on the impact of aluminum are not conclusive But we know that acidification can increase bioconversion of mercury to methylmercury and its accumulation in fish. In addition, since this rain can affect plants, it can also influence agriculture, for example altering the pH of agrarian soils, making them more acidic. This rain can also affect the constructions and public furniture. Here corrosion does play an important role since acidic particles interact with metal, stone and paint causing damage to the coating of buildings, statues and other elements. The presence of acid rain is also an indicator of the existence of torqueSO2 and NOX ticleswhich in themselves can be harmful to humans when they are inhaled. That is, the same particles that cause acid rain put our health at risk to a greater extent than acid rain itself. Consequences for the planet of acid rain We indicated before the compounds that cause acid rain can travel displaced by atmospheric winds and currents. This implies that sometimes the emissions of certain industrial areas end up causing problems in vegetated areas to hundreds or thousands of kilometers away. That is, acid rain can have global impacts in addition to premises. Can acid rain be avoided? The big question then is what we can do to avoid this. The answer is In emission control of the particles that cause this problem, that is, of sulfur dioxide and nitrogen oxides. The main sources of these pollutants are the burning of fossil fuels in different sectors (transport, electricity generation or industry) is largely responsible for This type of emissions. Various limitations introduced Throughout the last decades (The last the imposed in the maritime sector to sulfur emissions) have kept at bay the potential environmental disaster derived from acid rain.

The dubbing actors are planting in front of AI. In Mexico, the protest goes beyond image rights

by

The protest was this Sunday, but the discomfort had been cooking for weeks. Actors, broadcasters and creatives of the dubbing world mobilized in Mexico City to ask that their voice, their work tool cannot be cloned by artificial intelligence without consent. The trigger was a video published by the INE that, according to the organizers, the voice of the deceased would have used José Lavat generated by means of. Lavat was one of the most recognized dubbing voices in Latin Spanish, known for his role as a narrator in the Dragon Ball series. The impact was immediate. And the answer, too. A protest in the CDMX center. The mobilization took place in the monument to the revolution, in the center of Mexico City. It was not a massive march, but it was significant: not only because of the number –According to the National Association of Actors (ANDA)more than a thousand people attended – but for the diversity of voices who joined the claim. Among the calls and assistants were Ameloc, the Anda herself, the United Voices Organization, Ark Dubbing Mexico, the Esteban Siller Artistic Specialization Center (Ceartes), and also the International Association of Workers of the Show (AITE). As they collect in this Instagram postthe claim was shared by broadcasters, actors, technicians, directors and professionals of all industry levels. “It’s not just about actors,” said Alejandro Cuétara, representative of Anda, cited by Ecos Media MX. “We are supporting a group of directors whose work is also at risk, and the guild in general, which includes the other 60 departments that participate in a filming. From which Barre, to the director: we are all at risk.” From the street claim to Congress. The protest was not just symbolic. The participants took advantage of the call to demand concrete changes in Mexican legislation. The objective: that the human voice – as biometric data and work tool – is protected by law against unauthorized uses with artificial intelligence. As explained by Cuétara, in the last legislature there were up to 58 attempts to regulate the use of AI. “And none came to a discussion,” he lamented. Now, they support a new initiative promoted by local deputy Paulo García, which has already been raised to the federal level. What they ask, in the words of the Anda representative, is clear: “That there are the attempts of law that there are.” Cuétara also made a direct call to President Claudia Sheinbaum, asking her to take the issue as a legislative priority. “We are asking the president, Dr. Claudia Sheinbaum, to take the matter as her own and that puts a priority initiative to be discussed,” she said in the demonstration. The proposal is not limited to the use of voices in advertising or cinema: seeks broader recognition. “By controlling biometric, not only of talents, actors, actresses … the biometric of all Mexican. That your voice is part of your own image and that no one can or replicate it or use it to feed generative intelligences,” he said. It is a concern that is not only technique: it is also human. Therefore, from the Mexican guild they propose the creation of a new seal, which works as a declaration of principles. To the already known “made in Mexico”, they want to add a new one: “made by humans.” The government takes note (at least for now). This Monday, In its usual public interventionPresident Claudia Sheinbaum referred to the case directly. “They are right,” he said, in relation to the claims of the actors and announcers who participated in the protest. “They are people who dedicate themselves mainly to dubbing and, according to what they raise, even people who already died. This is not correct,.” Sheinbaum confirmed that she has already talked with the legal counselor and the Ministry of Culture to open a dialogue channel with the groups. “We are going to meet them to see which schemes of protection to their work and their voice have to be used to avoid the use of what is their main work tool, which is their voice, through artificial intelligence,” he said during the morning conference. The president admitted that the issue raises legal challenges – as the debate on whether the voice can be considered a biometric data – but also recognized the value of the trade. “The dubbing that is done in Mexico is very good. There are many people who dedicate themselves to it and you have to protect their work, their voice and everything that is associated with this important profession.” The dilemma is not just Mexican. What is played in Mexico is part of a broader debate. Throughout the world, artificial intelligence has begun to enter the creative processes, From script writing to films dubbing. Prime video, for examplehas already launched a pilot program to apply dubbing assisted by AI in titles that did not have a localized version. The plan, they assure, combines AI with human review to make its catalog more accessible. But not everyone see it with good eyes. In Hollywood, critical voices accumulate. Robert Downey Jr., for example, made clear that it will not allow That a digital twin of yours is believed or that its image is used with without consent. “Even if I am dead, my law firm will remain very active,” he warned.

The electricity network was not prepared for 2025

by

Although Bocachancla’s fame has been gained by the fame, Elon Musk can also be hit in his predictions. In mid -2024 predicted that this year we would see failures in the electricity grid because it was not prepared for current demand levels. And so it is being in large part of the world. Musk’s prediction. First, the shortage was from chips. Now, the bottleneck is in the voltage transformers. To the electrification that was already underway, the computing dedicated to the AI has been added, which is multiplied by ten every six months. “I have never seen a technology advance so quickly,” said the businessman in the Bosch Connected World 2024. What sounded to hyperbole has become a tangible problem just 18 months later. The difficulties in connecting new data centers, Light cuts during heat waves and The climbing of the night price of electricity They are already symptoms of an old and inflexible network that falls short for the times. The demand is runaway. In Italy, requests for connection to the network of new data centers They reached 42 gigawatts in March 2025a spectacular leap from the 30 GW registered at the end of last year. This 40% growth in just a quarter shows a voracious energy demand that mainly driven by AI. The energy appetite of generative AI is not a secret in Silicon Valley. Renewable energy has fallen short due to the slow expansion of batteries, and companies such as Microsoft, Amazon and Meta are investing in nuclear reactors To feed your data centers. A summer of blackouts. The summer of 2025 is serving as a hard reminder of the fragility of our electrical networks. On July 1, a heat wave caused a blackout in Florence. The cause: an overload in the network for the demand for air conditioning and overheating underground cables. It was not an isolated case. Countries like Kuwait and Bangladesh They decreed programmed cuts of electricity by heat waves. The networks operate with increasingly narrow margins, as we saw in Spain with the Bru what of April 28. There is no need for a catastrophic event to trigger a collapse: stations that control the tension They are at the limit. The background problem. Electrification, air conditioning and AI explosion is not the root cause of the problem. Neither does the lack of generation or storage. The background problem is the abandonment of infrastructure that connects everything. For every dollar that is invested in generating electricity, 40 cents are barely allocated to the networks, according to the International Energy Agency We are building an energy system of the 21st century on an infrastructure of the twentieth century. The IEA warning is as clear as that of Musk: “Without action, the electrical networks will be the bottleneck of the energy transition.” Elon Musk’s prediction was not a futuristic fantasy; It was a diagnosis of a disease that the electrical system already suffered.

Sending electricity without cables seemed to the future. Darpa has done it again, and the test has gone better than expected

by

What are 800 watts? More or less what a microwave consumes running at medium power. And 8.6 kilometers? It is an approximate distance between the stations of Atocha and Chamartínin Madrid. It is actually somewhat lower, but it serves to get an idea. That is the scale of Darpa’s last experiment: a system that managed to transmit real energy with a laser, in a straight line, without cables and with a receiver that turns the light into usable electricity. It may seem little, but it is not. The important thing was not the amount, but the test. And it worked. What exactly Darpa has done. The United States Advanced Defense Research Projects (Darpa) has successfully completed The first phase of a program called Power, designed to explore new ways of transmitting long distance energy. In their most recent test, carried out in New Mexico, they managed to send a laser beam that delivered about 800 watts for 30 seconds to a receiver located 8.6 kilometers. The figure is important because it exceeds the previous records: until now, the best documented result was 230 watts at 1.7 kilometers. Although the agency has not revealed how much power it was originally issued, it is known that the system was able to maintain energy flow for periods even longer than those officially reported. According to those responsible for the project, it was not about demonstrating efficiency, but viability. The essential thing was to check if it was possible to build a functional system in a short time. And they did it in just three months, from the initial design to the final execution. The receiver was developed by Technc Technologies and uses commercial solar cells already available in the market. The objective was not to optimize performance to the maximum, but to prove that this technology can be launched with accessible components and without complex manufacturing processes. How this technology works. The idea behind the experiment is simple to understand, although technically complex: send energy through the air with a beam of light, and that when it arrives it can be used as electricity. The DARPA system is based on an infrared laser that points directly to a receiver composed of a conical mirror and solar cells. The mirror captures the ray and redirects it towards the panels, which convert light into electrical energy. Part of the equipment used during the test The interesting thing is that no exotic components or photovoltaic cells were used to measure, as in many laboratories. Commercial cells were used, ready to use, which reinforces the idea that this technology can be viable out of paper. As we say, the performance, for now, was not the priority. Receiver efficiency is around 20 %. The Power Receiver Array Demo system achieved a new record by transmitting laser energy with more power and greater scope than ever During the test, diffractive optics were also used, an unusual resource in this type of transmissions, and an integrated cooling system was implemented directly in the optical parts, manufactured with additive printing techniques. None of these innovations was scheduled at the beginning. They were solutions that arose on the march, as they faced the challenges of the experiment. Why do it with laser and not with radio waves. Transmitting long distance energy is not a new idea. For decades it has been investigated how to do it with radio or microwave waves, but these technologies have physical limitations that include their effectiveness. As IEEE points outto work, they need large antennas and systems of Beamforminga technique that allows the signal to be concentrated in one direction. The longer the distance, the greater the issuer must be, and the more difficult it is to focus the beam with precision. Compared to radio waves, the laser can focus much better: a narrow beam can be created almost without dispersion, at least in ideal conditions, According to Eric YeatmanVice President of the College of Science and Engineering of the University of Glasgow. Of course, not everything is advantages. The lasers also disperse with fog, clouds or dust. In adverse atmospheric conditions, microwaves remain more reliable. But for certain applications, especially if we talk about aerial networks or transmissions in clear environments, the laser is difficult to match. For the Power project leader in Darpa, Paul Jaffe, if it does not work with optics, it will not work in any way. What does this advance mean (and what is not). Darpa’s experiment did not solve all the challenges of wireless energy transmission. Efficiency remains low, the system is not yet prepared to operate in adverse conditions, and the transmitted power, although notable, is far from what a commercial infrastructure would need. But that was not important. The important thing was to demonstrate that technology can work outside the laboratory, with accessible components and in realistic terms.

Sometimes, the most effective is the simplest. That thought Marco Figueroa, cybersecurity researcher, when last week decided to test The limits of Chatgpt. The proposal was as innocent as disconcerting: a riddle game, without technical attacks or explicit intentions. Instead of seeking vulnerabilities in the code, he focused on language. And it worked: he managed to make the system return something that, according to himself, should never have appeared on the screen. The result were generic key installation of Windows 10 For business environments. The key was to disguise him. What Figueroa wanted to check was not if he could force the system to deliver forbidden information, but if it was enough to present the right context. He reformulated interaction as a harmless challenge: a kind of riddle in which AI should think of a real text chain, while the user tried to discover it through closed questions. Throughout the conversation, the model did not detect any threat. He responded normally, as if he were playing. But the most critical part came at the end. When introducing the phrase “I Give Up” – I rindo – Figueroa activated the final answer: the model revealed a product key, as it had been stipulated in the rules of the game. It was not a casual carelessness, but a combination of carefully designed instructions to overcome the filters without raising suspicions. The filters were there, but they were not enough. Systems such as Chatgpt are trained to block any attempt to obtain sensitive data: from passwords to malicious links or activation keys. These filters are known as Guardrailsand combine black lists of terms, contextual recognition and intervention mechanisms against potentially harmful content. In theory, asking for a Windows key should automatically activate those filters. But in this case, the model did not identify the situation as dangerous. There were no suspicious words, or direct structures that alerted their protection systems. Everything was raised as a game, and in that context, the AI acted as if it were fulfilling a harmless slogan. What seemed harmless was camouflaged. One of the elements that made the failure possible was a simple obfuscation technique. Instead of writing directly expressions such as “Windows 10 Serial Number”, Figueroa introduced small HTML labels between words. The model, interpreting the structure as something irrelevant, ignored the real content. Why it worked (and why just worrying). One of the reasons why the model offered that response was the type of key revealed. It was not a unique key or linked to a specific user. Apparently it was a generic installation key (GVLK)such as those used in business environments for massive displays. These keys, publicly documented by Microsoft, only work if they are connected to a KMS (Key Management Service) server that validates network activation. The problem was not only the content, but the reasoning. The model understood the conversation as a logical challenge and not as an attempt to evasion. Did not activate its alert systems because the attack did not seem an attack It’s not just a key problem. The test was not limited to an anecdotal issue. According to Figueroa himself, the same logic could be applied to try to access another type of sensitive information: from links that lead to malicious sites to restricted content or personal identifiers. Everything would depend on the way the interaction is formulated and whether the model is capable – or not – to interpret the context as a suspect. In this case, the keys appeared without their origin being completely clear. The report does not specify whether this information is part of the model training data, if it was generated from already learned patterns, or if external sources were accessed. Whatever the road, the result was the same: a barrier that should be impassable ended up giving up.
