Its solar panel in tandem already exceeds the theoretical limit of silicon

by

The efficiency of solar panels always andStá in object of studyand the only country capable of developing new advances is China. In fact, the company Longi has achieved have even a certificate of the National Renewable Energy Laboratory (NREL) of the United States. Short. The Chinese giant of the solar modules He has achieved A new record in solar energy conversion, reaching 34.85% efficiency in a pervskita solar cell in two terminal tandem. In this way, Longi has managed to overcome The previous 34.6% record that Longi herself held two years ago. A key technical advance. To understand the feat, it is important to know the tandem design. This structure combines an upper cape of Perovskita and a lower crystalline silicon, allowing to capture different ranges of the solar spectrum. Through a technique called bilayer interface passive, two layers are introduced that improve the passage of electricity between both active layers. On the one hand, lithium fluoride (LIF) acts as a barrier against load losses. On the other, the ethylendiamium diyoduro (EDAI) fills the nanometric scale holes, ensuring a more efficient load extraction. It’s not just about materials. The Chinese company has also redesigned the structure of the crystalline silicon, making the frontal surface more rough to facilitate the adhesion of the Perovskita and maintaining a standard texture in the rear to optimize the capture of infrared light. This texturing improves the absorption of light and, therefore, the efficiency of the panel. Achievement is not less. Apart from overcoming its own record, the Chinese company has overcome The so-called Shockley-Queisser limit. In other words, it has managed to exceed the maximum efficiency limit marked by 33.7% for a single union. However, tandem cells, which combine different materials such as Perovskita and silicon, can overcome this limit by taking advantage of a broader range of the solar spectrum from the theoretical aspect. For example, research has shown that tandem cells can achieve higher efficiencies 40%and theoretically, some configurations could reach up to 60% . Institutional support. Thanks to the participation of the universities project such as Suzhou and Hong Kong (HKPU), together with the Huaneng Clean Energy Research Institute, They have allowed A Longi perfects its silicon hetero -union technology and optimizing manufacturing processes, bringing Tandem technology to a more commercializable level. The next challenge. Longi has shown that the solar efficiency roof remains a mobile objective. However, he will now have this laboratory technology to the mass market. The durability of tandem cells, production costs and industrial scalability They will be key factors To determine if this record becomes a commercial standard or another technical advance without immediate practical application.

A power in nuclear energy is emerging as the best alternative to Russia and China for the West: South Korea

by

Russia and China are indisputably two powers in nuclear energy. So are USA, France and other western alignment countries. Although these states have a bulky nuclear plant park which really places them at the forefront is Your ability to develop new technologiesand in this area the most promising reactors are The fourth generation. Russia and China already have at least A reactor of this type in operationand the US, France, India, Canada or Japan are some of the countries that plan to have them in the future. However, there is a power in nuclear energy that often goes unnoticed. We all know that South Korea has a lot of weight in semiconductor industries, consumer electron Nuclear energy as a strategic pillar Not only within its mix of electricity generation, but also as an engine of innovation and export. South Korea is the most consistent alternative to China and Russia Currently South Korea has 26 Nuclear reactors in operation with an approximate total capacity of 25.7 GWE. This infrastructure contributes to its Mix with 30% of electricity, although the commitment of this Asian country for nuclear energy does not end here. And it is that between 2026 and 2033 the construction of four more reactors will conclude that will have a power of 1,340 MWE each of them, so the total installed power in this country within less than a decade will exceed 30 GWE. Its APR-1400 reactors incorporate passive security systems that allow them to compete from you with the machines exported by Russia, China or the USA In any case, as I have anticipated a few lines above, which has placed South Korea to the avant -garde and has positioned this country as One of the largest exporters in the nuclear sector It is your ability to develop your own technologies. Their APR-1400 reactors incorporate passive security systems that allow them to compete from you with the machines exported by Russia, China or the US. In fact, South Korea has already exported this reactor to the United Arab Emirates and is negotiating with the Czech Republic and Poland to sell their technology. On the other hand, this Asian country has also opted for fourth generation nuclear fission. Your smart reactor (System-Integrad Modular Advanced Reactor), what is An SMR type design (Compact modular reactor) is in the process of certification to be used in desalination and electricity generation facilities. It also prepares fourth generation reactors refrigerated by sodium, such as the machine outlined in the Kalimer project, although it is not yet clear when the first South Korean commercial reactor endorsed by this technology will come into operation. South Korea has a very ambitious plan: wants to capture at least Ten international contracts until 2030. His first project abroad has been Barakah’s nuclear power plant in the United Arab Emirates, and It has been a success. As I mentioned a few lines above, Czech Republic and Poland are presumably will bet on South Korean reactors, but South Korea nuclear energy companies are also trying to take contracts in Egypt, Finland, the Netherlands, Sweden, Turkey and even in the United Kingdom. If only some of them get to fruition this Asian country will become a full competitor in the international market of China, Russia, France or the US.

Steve Jobs presented an emulator in 1999 to turn any Mac into a playstation. Sony did not even grace

by

January 1999. MacWorld Expo de San Francisco With Steve Jobs on stage. After a presentation loaded with video games and focused on how well those video games run in front of the PC versions, Jobs made Una of the most controversial presentations that have been seen in a scenario of a company of Apple’s reach: that of a PlayStation emulator. Steve’s goal was for each MAC to become a PlayStation I could run games like ‘Crash Bandicoot‘, something possible by the hand of a company called Connectix and of a software called Virtual Game Station. In an ecstatic Sony for the success of their console, they should not give credit to what was being affirmed in one of the most projection events worldwide. The punishment for the creators of the emulator? Be bought … by Sony. Turn each mac into a playstation In 1998, the field of video games for Mac was … Campo. In PC you could enjoy the Lucasarts great adventuresof ‘Warcraft‘, from’ Devil ‘, De’Age of Empires II‘And that same 1998 jewelry was born’Starcraft‘ either ‘Half life‘, But the situation in Mac was very different. There were some projects, yes, and companies like Bungie had interesting games such as ‘Marathon’, but the PC win was incontestable in the entertainment segment. A young programmer named Aaron Giles came up with one thing. Hey, if the MAC has a CD reader and the USA PlayStation CD, Why couldn’t a PlayStation game into a Mac? Giles worked for Connectix, a company founded in 1988 with a very curious story. They developed pioneer software for Mac, but with each new version of Mac OS, Apple ‘stole’ those functions that they had developed to include their own. What Apple did was buy Shareware versions of the same concept that Connectix developed, and so they did not have to make deals with the Connectix itself. Not only did they do hardware: they also took the mac from the sleeve Quickcamone of the First webcam in historythat They sold to Logitech in 1998. But the emulation was the strong point of this company and the focus of many of the developers of the same. Let’s go back to the history of Giles. The programmer began working on the project in 1998 and the truth is that, being able to read Sony’s games with a standard CD-ROM reader, the hardware part was solved. “Only” You had to focus on emulating the bios And the PlayStation environment, but by January 1999 I already had it ready. Thus, on stage, Jobs announced to the world the Game Station virtual emulator, or VGS. “Our goal is to have the best game platform in the world,” said Jobs, who showed below a photo of a playstation. “This is another video game console, the most popular at this time. Wouldn’t it be great if we could also play some of your games?” With that lapidary phrase, Jobs presented the Connectix product adding that it was an emulation software that would sell for $ 49 and that “turn your Mac into a Sony PlayStation.” Less than half of what cost a PlayStation. I imagine Sony’s executives spitting the sake when they learned that Jobs had said that. Hallucinatory “There are hundreds of games that can reproduce from the PlayStation,” said Jobs, who gave way to a Phil Schiller – world marketing director of Apple products – that did not reduce the enthusiasm or tone. Steve giving way to Phil before playing ‘Crash Bandicoot 3’ “This is very cool,” Phil began. The possibility of using a Mac, my MAC, to execute all the great playstation games quickly and economically only putting the game is a fantastic idea ” AND, Neither short nor lazy, he began to play ‘Crash Bandicoot 3’. “It is Sony’s most popular game at this time,” said Phil without cutting off a little (something that today is absolutely unthinkable) and … he began to play. That title had come out just a few months before and ran at 100% speed in a Mac (after a couple of pulls) simply by putting the CD and running VGS. The question was how. How they had been able to emulate perfectly in a IMAC G3 At 233 MHz an RISC processor at 33 MHX, being this of a completely different architecture. And the most impressive is not that, but Giles got it without using a Sony code line. Before continuing I will summarize How an emulator works. It is something that recreates the hardware and system of a console on another platform. In this case, a program that recreates a PlayStation in a MAC. The emulator makes “translator” In real time among the game instructions, which are designed for consoles hardware, to the instructions of the host device. It is something that consumes many resources because you must do a double job, but the really complicated thing is to emulate the BIOS. BIOS means Basic Input Output Sustm and is the essential software of the console that controls the start and interaction between the hardware and that console. For VGS to work, he had to emulate that bios. Giles contacted Sony to help them with the BIOS of PlayStation and, before the Japanese refusal (and an cessation and withdrawal letter by Sony), the programmer did something as absurd as great: thoroughly investigate the machine, study the original bios and rewrite it from scratchlike an own bios. It was absurd because it was a titanic task, but also great because Sony couldn’t do … nothing. Sony’s disbelief That same 1999, Connectix launched VGS for Mac and most games ran fantastically on Apple computers. There were characteristics, such as the vibration of the PlayStation command, which did not work, but it was something that impacted allowing, for 49 dollars, all the owners of a Mac have, in practice, a playstation. For sale of games it would not go wrong because a window of potential users opened, but as we said before, Sony should … Read more

A 5,000 hp engine. And they fulfilled

by

We are tired of seeing races between countries such as United Arab Emirates or Saudi Arabia to see who has it bigger. The skyscraper, of course. Although we could talk about cities, Like Neomor of authentic pharaonic works that are still difficult to assimilate Like The Line. Or new buoyant businesses, Like data centers. Herein diversification From the business of the oil countries, in this intention to sell to the world as leading nations in multiple sectors, the automobile market could not overlook either. And how could it be otherwise, when a Dubaiti company got into the project to create its own car did not think of a simple, practical vehicle for the masses and cheap to produce. You had to think of a hypercoche. Bugatti? Koenigsegg? Who are those? You had to create a car with power. With a lot of power. Were 5,000 CV enough? An engine without wheels More than a decade ago, a car focused all the looks of the Dubai Motor Show. His name was Devel Sixteen And his proposal was simplistic: becoming the most powerful car in the world. To do this, they said, they were clear that the recipe had to go through a gigantic engine. Put to dream, why not dream about the largest: an engine of V16 and 12.3 liters and four gigantic turbos for Generate 5,000 CV of power. The promise is that the car could reach 560 km/h of peak speed. The project, back in 2013 it seemed so demential that it seemed impossible to comply. Using 16 cylinders in a street vehicle is something that Bugatti had already used since 2005 with the launch of the Veyron. In this case Use a W16 engine. That is, it uses two V8 engines to add those 16 cylinders. And, however, the company reached consider the creation of a V18 engine. The project had to cancel because it was more realistic to “paste” two engines already known within the Volkswagen Group. However, that Bugatti V18 aspired to put more than 600 hp on the street. To open the mouth in the new decade, Koenigsegg presented the Agera, a car that stayed “alone” in a V8 biturbo engine to fold with the number of the thousand power CV. The Ferrari Laferrarifor example, stayed at 800 hp of power in 2013 and already used an electrical system derived from formula 1. That same year a completely unknown Dubaiti company arrived to say that a car was going to put a car with a 5,000 hp engine on the market was received Between the joke, the disbelief and the expectation of who trusted petrodollars. Those petrodollars invested in paying the development of Steve Morris Engines, a specialist in preparing vehicles who just confessed that the car could have come to fruition. In fact, he confirmed that he did fulfill and that, at least, a 5,000 hp engine was seen that only the rest was missing. That is, a car up. In it videoSteve Morris explains that he used the same formula as the Volkswagen Group. That is, project the union of two V8 engines of general Motors origin for which it created a specific ECU. With her, he says, he could have reached up to 6,000 hp of power, according to his calculations, but finally stayed in a more humble 5,076 hp. And he knows the exact figure because, in fact, had to buy a specific power bank since I did not have the tools to be able maximum performance to such a beast. He tells everything with a table with a craft tree of huge size, which gives an idea of ​​how far such an experiment could have grown. The problem, therefore, was not in the engine and that seemed the most crazy. The truth is that it makes sense because the great challenge should not be to develop the propeller, the problem is how to lower that power to the ground and make the car a practicable hyperdeportivo. It is something that the companions of Motorpasion In 2021 when it was learned that the project continued. Now it seems that it is canceled or, at least, in pause. Not only is it to find the way to stuff such an engine in a car, you have to look for ways to transmit that power to the wheels Without everything jumping through the air and find the chassis rigid enough to tame the envy of it. In addition, the latest releases of Bugatti and Koenigsegg that they have begun to glimpse that you can Break the 500 km/h border They have put on the table the need to find a formula for tires that can withstand such a power without compromising the safety of passengers. Yeah, An engine of more than 5,000 hp was achieved For Devel Sixteen. It only remains to get ahead of a car.

In Europe, more rent among women always equals less children. A country has managed to change it: Sweden

by

A while ago Martin Kolk, a demographer from the University of Stockholm, asked an interesting question: does the income level influence the number of children who have men and women throughout their lives? And if so, to what extent? To answer these issues he dedicated himself to combing the fertility and income databases of his country, Sweden, of the last decades. The result He published it In 2022 in Population Studieswhere it reveals a change in tendency in Swedish society that, like Kolk himself stands outcould move to other nations. Your conclusion It is as simple as it is interesting: Sweden seems to have ended The paradox that often the richest people are the least children. Issue of children and money. Having children demand money. Last year Save the Children He made accounts And he concluded that, on average, in Spain he leaves 758 euros per month, if they have as soon as all the factors involved in parenting, from food to education, health or the need for a broader housing. Despite that reality (paternity costs) there are many low -per capita income in which the fertility rate is Very superior to that of other richer nations. For example, it occurs with Niger and the United Kingdom. The other question. Another phenomenon that demographers have observed in the past, such as remember The Institute for Family Studies (IFS), is that in the rich countries women with the highest level of education and labor perspectives have fewer children. “While the theoretical arguments that (…) affirm that the richest parents should be able to have more children, industrial societies of the twentieth century have shown the reverse pattern,” Kolk points out. The United States offers A good example: The highest birth rate is achieved by the poorest families. The big question is … Is that trend still true? Diving between data. To answer that question and others as to what extent the income affects birth or, in reverse, how motherhood in income influences, Martin Kolk opted for a peculiar strategy: took into account the accumulated income by its compatriots throughout its life, analyzing in detail the 40 -year Swedish data and income for each birth cohort. Its analysis covers a wide period that extends to the 1940s, 1950s, 1960s and 1970s, valuing the “accumulated income” in Swedish crowns. The analysis, of course, has its biases. Kolk focused only on the Swedish population, leaving even the people who had emigrated. However, his work is thorough: he analyzes people between the ages of 20 and 60, valued the income that they “accumulate” when they reach 50 years and took into account factors such as available income or aid to fatherhood. Men: richer, more children. In the case of men, he appreciated a fairly clear relationship between accumulated income and fatherhood that has not left great surprises over the years. “The richest men are the ones who have the most children and that pattern has accentuated over time. At higher income, more children,” Comment The Stockholm expert, which even warns: “It is increasingly frequent that men with very low income do not have children.” In his study, Kolk points out that it is not so much that the richest men accumulate a lot of offspring as it is more frequent that they have two, three or four offspring compared to other men with a more adjusted income level. And what about women? It is there where research gets interesting. Among the Kolk women did appreciate a trend change. And of course. While between those born in the 1940s and 1950s, lower income (accumulated income available) was accompanied by more children, which did so over the subsequent years (between 1960 and 1970) showed the opposite photo: the highest income indicated greater offspring. “The trend is reversed: the pattern is more similar to that of men”, Confirm. The full photography is somewhat more complicated. Women with the highest income, for example, are not necessarily those who have the greatest number of children and the trend is not exactly the same if we talk about “accumulated income” or profits. But from the University of Stockholm they appreciate in any case a “significant change” in the fertility pattern of women. And a change that breaks with what was the general tonic for a long time. “The results contrast with those of many other high -income countries in the twentieth and twenty -first centuries, in which researchers have shown that it was more common to have many children among men and women with lower income.” Looking for the causes. Detected the change in trend, the next question is obvious: why? What has caused it? Kolk points to social changes (especially those related to the labor market) and family policies of Sweden. Unlike what could happen decades ago, when many of the women who had children were housewives dedicated to home care, now “women do not have to choose between having children and follow a career.” “What is observed is a transformation of a society where women, to some extent, had to choose between a professional career or have children to a society in which these decisions no longer have to make.” Among the women of the 1940s and 195th, those of lower income were often housewives. It is demography … and above all it is economy. The study shows another valuable reading, especially for countries that have seen how their fertility descended over the years. Research shows that in general people with very low income levels do not usually have children, something extensible to men and women. Also clarify that this pattern “It has accentuated over time”which confirms to what extent the economic factors influence motherhood. “Today, an increasing number of women and men with low income in Sweden decide not to have children,” concludes The expert as an example. “The paradox is left behind”. For IFS Kolk’s research reveals that “at least in Sweden the paradox that the richest people have less children seems to be left behind,” … Read more

The Italian Carabinieri are fed up with Alfa Romeo Tonale. Alfa Romeo is also fed up with the Carabinieri

by

For many of us, the car is a means of transport and a pleasure when traveling. For security forces, cars They are essential tools In your day to day. Sometimes, also a nightmare, as is the case with the Alfa Romeo Tonale owned by the Carabinieri -the Italian counterpart of the Civil Guard-. And a scandal so large has been mounted that Alfa Romeo threatens to denounce the Carabinieri if they continue to stain their image. Historical relationship. If you have ever been in Italy, you have surely seen that the Alfa Romeo are the cars of the security forces. It has also been seen in films. This relationship It comes from afarof the 50s, to be exact. The security forces needed fast cars and the Alfa Romeo were the chosen ones. Alfa Romeo 1900 became the vehicle of both the police and the Carabinieri. They were fast, agile and easy to drive, which made them ideal cars for that police work. Over the years, fleets have been renewed with new models, some high performance. But in 2023 it was the turn that a SUV occupied the police garages next to the imposing Giulia Quadrifoglio. The Giulia Quadrifoglio The tonale. To the Alfa Romeo Tonale Things are not going well. This SUV did not start well in the market due to Poor sales. It is a car designed to enjoy driving quietly, without being nervous and enjoying a powerful infotainment system. And these concepts are not aligned with police requirements. In June 2023, however, 400 Alfa Romeo Tonale in its hybrid version of 163 hp with 1.5 engine and automatic change were delivered to the Carabinieri. They had been modified with lights, siren, partial armor, police radio and detainee cell, but the motorization is not the most powerful that can be chosen in that family. THE JALEO. They were definitely not happy. This May, the union union that represents part of the Carabinieri has presented a formal complaint Before the prosecutor of the repubblica of Rome alleging that the Tonale is inappropriate for the police service. Your arguments? It is a car with stability problems and road behavior, especially in emergency situations such as high -speed persecutions, does not grab well and the step is not safe on unstable roads. This puts both the safety of the agents and the effectiveness of the missions, but the complaints do not stay there. UNARMA continues to argue cannot “accept that colleagues work in potentially dangerous conditions” and that “it is the duty of the administration to guarantee safe, reliable and fully appropriate vehicles to the operational demands.” And the alpha Romeo Tonale And Stellantis response. Imagine being the brand behind the creation of a car that came to relive a not very prolific segment that runs from Bruces with a security body that will squeeze the car saying that it is unstable and not sure. Well what the brand has done is … counterattack. In a releaseAlfa Romeo responded with the following official note: “Our vehicles comply with the strictest safety standards and are subject to rigorous evaluation tests. Alfa Romeo remains completely available to the authorities for any clarification and reserves the right to defend their image and reputation before the competent bodies.” In the rest of the note they limit themselves to reviewing that historical relationship between the brand and the Carabinieri. In the end, it is a morrocotudo mess that stains a 75 -year relationship that has contributed to that good image of the Alfa Romeo in their native country. But something important here is that, from the brand’s porpholio, the tonale is cheaper than the Stelvio, another SUV, and much more than the giulia (both the standard and the quadrifoglio preferred by the Carabinieri). We will see what happens, since the National Secretary of Unarma ends the statement stating that they will not stop “until everything that happened is clarified.” Images | PetrachpStellantis In Xataka | The controversy of the 380 unemployed electric cars: what do we know about the Civil Guard and the lack of loaders

The best PROMPTS to save working hours and do your homework with Chatgpt, Gemini, Copilot or other artificial intelligence

by

Let’s tell you a series of prompts for Save work hours using artificial intelligence To perform your homework. In the examples we are going to use chatgpt, but they are prompts that should also serve you with other AI, such as Gemini, Copilot, Deepseek or any other. In each of these examples we will give you both the explanation of what you are going to get as the prompt to do so. These prompts are generic, it is not copy and paste, since in many cases you will have to modify them to specify what you want me to do to you. They are like templates, go. Learn concepts in the simplest way This is one of the most classic and veteran tricks of artificial intelligence, that of Ask him to explain something as if you were 5 years old. You can also modify it to explain it to another level, as to a person of another age like 12 years in the event that you need something slightly more advanced. Sometimes you can find terms and concepts difficult to understand, and When someone tries to explain it you may stay the samein the same way that when you read explanations you cannot finish understanding it either. This is where this prompt comes into play, with which you will save a lot of time trying to understand it by reducing the explanation to the lowest level: “Explain to me the theory of relativity as if I was five years old” And if this is not enough, you can also ask for extra context: “Explain to me as if I had the theory of relativity five years and why it was so important for history.” Check texts before sending or publishing them In the event that you work by writing texts, or that you have to review a job you have written, you can also Ask the AI ​​to check your writing To find spelling failures. It can also help you with grammatical errors or typographic failures of those that can be escaped to all. The way of proceeding is first to give the instruction, and when the OK you hit the full text. “I’m going to send you a text and I want you to review it, and tell me the spelling and typographic errors that I have” In addition to this, you can ask you to do a more thorough analysis, taking into account other aspects: “I’m going to send you a text and I want you to review it, and tell me the spelling and typographic errors that I have. I also want you to tell me the words that I have repeated too much, and that you tell me how to improve it.” Change the tone of your writing Imagine that the problem is no longer so much in the text and spelling as in the way you have expressed yourself. Maybe you have been more colloquial when it should be a serious or professional text, and here there is little to do beyond rewriting everything. However, another thing you can do is present the text to ChatgPT and Ask him to rewrite him by changing the tone in which it is written. Again, it is best first to give the order and when I tell you that ok then hit the text. The prompt would be something like this: “I’m going to send you a text, and I need you to analyze it and rewrite it in a much more formal tone” As you can understand, you can modify it to specify a different tone. You can also add any detail or thing that you think you should take into account when rewriting it. Use AI as a translator Another of the important functions of artificial intelligence is that can act as a translator. In addition, in many cases IA can surely translate better than tools such as Google Translator, and you can write very long texts to translate them. “I’m going to send you a text in English, and I want you to translate it into Spanish from Spain” Another of the advantages when using AI as a translator is that you can customize the way you want translations to be made. You can take advantage to change the tone, so that it makes you corrections, or even simply ask that the translation is natural for a Spanish reader. Create exams to test your knowledge Imagine that you are getting the driving license or you are opposing, and you need test your knowledge. For this you can search for pages with tests on the Internet, but you can also ask Chatgpt to do a test on a specific topic. Here, just remember that artificial intelligence bots can make mistakes, and it is possible that not all questions or the tests of the test are true. However, despite it is or remains a very interesting tool that should be taken into account. So you can ask you to take the exam “I am an opponent and to practice for my exam I need to improve my knowledge about a law. Could you ask 30 test questions about Law 39/2015, of October 1, of the common administrative procedure of public administrations?” After asking for the exam, you can also ask to tell you what questions are correct and reason why. “Now you can explain what is the right option in each of the questions, and why?” Create study sheets Another useful thing for students is Create study sheets or flashcardswhich are small basic data cards that help you memorize concepts, formulas or dates. They can be very useful for studying for an exam and need to memorize key data. “I want you to do a study tab or flashcards to learn about relativity.” It also helps teachers Beyond the exams to test, if you are a teacher you can also use AI to Create exams for your classes. It is true that perhaps it is not … Read more

A man wanted to put order in the fish of the fish market. His invention financed one of the largest cars collections in Europe

by

In everyday life, there are inventions as simple as it is essential that, however, they often go unnoticed. One of them is the “shift” ticket dispenser that we find in fishing, butchers and supermarkets, and that has ended the discussions in Waiting tails. Behind this invention is Rodger Dudding, a British who with his business vision kneaded a great fortune that allowed him to fulfill his great dream: to gather one of the Collections of more impressive cars from the United Kingdom and Europe. As They counted in Motorpasionthanks to his ingenuity, today we not only enjoy more orderly linesbut we can also contemplate one of the largest private collections of classic cars in Europe with More than 450 cars ranging from Rolls-Royce, Aston Martin or the Ford T, to such humble models as the Fiat Topolino. Rodger Dudding and the invention that changed the queues Rodger Dudding was born in the United Kingdom and is a training engineer. At 87, he is responsible for the distribution in the United Kingdom of one of the most used inventions in businesses around the world: the queue management system based on a Shift ticket dispenser. In 1970, Dudding He founded Lonsoa company that is still active, and began to manufacture the ticket dispensers that have avoided more fights and confusion when waiting for the turn and supermarkets. The classic red dispenser quickly became a standard, facilitating life to both customers and merchants. Even today, a significant percentage of Dudding’s benefits comes from the commercialization of this system, which remains essential in businesses of all kinds. Passion for cars With the money obtained from ordering the tails of the shops, Rodger Dudding decided to invest in his great passion: classic cars. Although, the millionaire collector has preference for British models, in An interview For the channel Bellow the Radar Carshe confessed that he had not been able to resist to the Ferrari or any beautiful car that was shot. Dudding said that, at first, not his intention to start a collection as such, but was limited to going buying the cars they liked. One day, his wife got fed up with his garage full of old cars, so Dudding acquired An old tram garage To save your cars. Almost without realizing it, the garage with capacity for about 120 cars He was smallgiving rise to the current collection that already It occupies three stores. The Dudding collection, known as Studio 434includes models of all times and styles: from 1911 models, such as Ford T, through racing cars prior to World War II or exclusive Limited luxury editions. The collector millionaire confesses that, beyond the Ferrari, Rolls-Royce or Aston Martin that form his collection, there is only one car through which life would be played to rescue him from a fire: a Morris Minor that his father bought again in 1952 and that his sister inherited. He bought a more current car equivalent and incorporated his father’s car to his collection. According to estimated Dudding, the collection is valued in More than 40 million pounds sterling (which are about 47.7 million euros) and includes, in addition to cars of all kinds, motorcycles and objects related to the motor world. His fetish: Aston Martin Lagonda Despite the diverse of the Studio 434 collection, there is a model for which Dudding feels a special predilection: Aston Martin Lagonda. The millionaire has no less than 24 units of different versions, including the first and last one that were manufactured. The Dudding collection had 26 lagonda in its catalog, but, as confessed in its interview with Bellow the Radar Carsthey made a purchase offer for them that he could not reject and were to be part of other collections, so he dispensed with two of them. One of the most striking aspects of Rodger Dudding’s collection is that All vehicles are in perfect condition of operation. The collection has a motor engineer who works full -time by cyclionally reviewing each and every one of the cars and has them A day in maintenance. In addition, provided that the British climate allows it, the revised vehicles go around the storage apple so that the suspensions and mechanical elements They move. Studio 434, the company that manages the collection, is responsible for renting some of these Classic cars for eventsweddings, movies and television series, thus contributing to the conservation of the collection that has become a reference for motor lovers. Some of the cars in this collection have participated in series such as The Crown or in the saga of Harry Potter.

A programmer did not like how his coffee maker extracted coffee. So he dedicated 100 hours to hack her

by

Few things give more anger than to play with an extremely simple device that does not respond exactly as you want. An example is the appliances that should be at our service, but sometimes they go from us, they are unnecessarily complex Or they have many functions, but not as simple as “don’t automatically turn off.” That is what a software developer was found to Buy a coffee makerand made the most logical decision. Return it? No: Hold it. And be careful, because that of ‘hacking’ the coffee makers is not so weird. Functions vs User. Gabriel Ciubotaru He is a software developer, but also an expert in cybersecurity and reverse engineering, among other skills. In a recent conference at the Defcamp 2024 (a relevant cybersecurity and hacking conference at European level), Gabriel told how he had acquired a coffee maker that he liked a lot, but that had a very annoying function: at 30 minutes of being on, he automatically went out. It is a function to save energy, and that is fine, but the problem is the enormous contradiction that arises when, every time it turns on, it performs a refined cycle that expels a moderate amount of water. In addition to water, it was a loss of time and Gabriel search between the options until finding a higher time limit: three hours. As he made a coffee every four hours, it was not adequate for his rhythm of life and decided to open the machine. Hold the coffee maker. The task seemed simple: extract the motherboard, locate the microcontroller and identify the system programmed to automatically turn off the machine and perform that refined process, change the firmware with the desired time value and reassemble the machine. The reality is that it found that component relatively easy, but the complicated thing was to find, throughout the code tangle, the lines that it should modify so that the coffee maker went out when he wanted. He did it, looking at a code that controls the warning icons that shows the coffee maker screen so that the user identifies his status following the instructions of the manual, so he modified those values, the modified code rose to the microcontroller and … ready, the coffee maker now works as he wants. I have explained it in a very simple way, but in Gabriel he gives all the details in his conference. He also comments that he has saved 30 seconds a day by investing 100 hours of work to hack the coffee maker, but that it is something that has been totally worth it because now it is the device that works as the user wants. More homemade projects. It is clear that not everyone has the resources, desire, time or interest in getting what Gabriel has achieved. Those 30 seconds, to many, would not be bother us, but what is also true is that there is an interest on the part of some users to hack their coffee makers in one way or another. One of the most popular coffee makers is Delonghi dedicates. It is what I have and has a series of default values ​​that respond to the amount of coffee extraction time. For a pressurized portfilters like the one that carries the machine, they are adequate, but when you buy a portfiltros in the air, these values ​​fall short and we have a way of programming a slower extraction based on combining its three buttons. It is something indicated in the manual, but what is not indicated is how to achieve a better milk foam. The sparkler included is functional, but not perfect. A trick to have more control over the process is to remove the metal part of the sparkler and keep the rubber, with a much thinner nozzle. Thus we can better control the process, but there is a problem: due to the pressure, the nozzle jumps. The solution? Set that mouthpiece to the coffee maker through a flangeand problem solved. Removing functions to the machine. That is a very simple modification, but there is another that is perhaps more interesting because it directly affects how coffee knows. In filter coffee makers, the most common is that the base has a resistance that keeps hot coffee for a longer time. This implies that coffee ‘cooks’ by extraction, but then continues to warm up with a high temperature base that modifies its flavor. It is not ideal, but even expensive machines (and that, supposedly, its manufacturers should know that it affects the flavor) implements it. Therefore, a common modification in this type of coffee makers is to open them and remove the cables that give energy to that resistance. It does not affect anything to the operation of the coffee maker when preparing coffee, but you eliminate that base that continues to cook the coffee once extracted. It is a modification that gives more “fear” than placing a flange, but it is worth it because, as I say, it has a direct influence on coffee. And as that modification there are many others, such as placing a more quality milk foamer in the aforementioned dedicate or changing the water pump pressure, Change the diffuser of water in a moccamaster … More serious implications. Ok, these cases are curious and allow to improve the functioning of the coffee maker, but really hacking a coffee maker is a serious thing. It is something that Martin Hron, Avast Security Researcher, demonstrated to the HAHKE AN INTELLIGENT COFFEE. Focusing on the first generation smartger, Hron got access to the system and realized that it worked as a unprotected Wi-Fi access point, with unbalanced connections and that allowed firmware updates without authentication. What did you demonstrate? Two things. On the one hand, which could rotate the mill without control, waste boiling water or emit beeps. He could also show a rescue message with a URL in which to make the payment so that the coffee maker ceases to behave … Read more
