problem

His biggest problem has not been money, but balance

by

Passing a vacation aboard a cruise is a tourist option increasingly demanded even for travelers high purchasing power. However, Mario Salcedo, a millionaire who made a fortune in finance, decided 25 years ago to turn his day to day on a vacation. Since then, he has been linking cruise trips making these colossi of the sea In your home. However, that life of luxuries aboard some of the biggest recreation ships has taken its toll: it has lost “its earth legs” and is no longer able to walk in a straight line when it arrives in the port. Live on vacation. The Millionaire of Cuban origin told In 2019 a The New York Times that he was never interested in forming a family, so his life on the mainland was only to work and work. So one day he decided to leave his apartment behind in Miami and cruise. The experience impacted him so much that since then he has been linking one cruise with another and now his house has several covers, swimming pools, dance tracks and some fleeting neighbors with which he socializes whenever he can. After being a regular between the passage of the Royal Caribbean companythe crew already knows him as Super Mario. “I have no vacation. People come here to spend a vacation. I don’t, I’m here to live my life,” explains the millionaire. Life on board. The Millionaire Investor uses a reserved table on one of the covers of the cruise in which it can be read on a handwritten sign “Super Mario’s office”. Obviously They do not refer to the Nintendo characterif not to the place from which the millionaire sits every day for a few hours before his laptop to telework. In this way, the more than 1,154 cruises that he has completed in his life on the high seas has been paid. The Millionaire claims to dedicate between $ 70,000 and $ 100,000 a year for their trips. The millionaire counted in An interview For Condé Nast magazine, who reserved an inner cabin without a balcony, because “I do nothing in my cabin but shower, dress and sleep,” he explained. The rest of the day could be found in his “office”, socializing with other travelers or dancing in one of the ship’s dance rooms. To avoid having to constantly changing cabin, Salcedo plans it with 150 reservations in advance, linking a journey with another. The worst of living in a cruise is to get to port. Everything would indicate that the greatest cost of living in a cruise is money. However, for “Super Mario” the greatest sacrifice is to go down to the ground. After more than 25 years rocked by the swing of the waves in the best cruises, the millionaire has developed a rare disease called Landing disease. This is a rare disorder that affects the vestibular system of the ear that affects the balance giving a constant sensation of movement even when it is stable and motionless on the mainland. It is popularly known as “earth legs.” Usually, this is a disorder that remains as much for a couple of days, but when your life transcurns on the high seas, and you only pass a total of fifteen days a year on land, the disease becomes chronic. “I have lost my land legs. I swing so much that I cannot walk in a straight line. I am so used to being in ships that I feel more comfortable than on land,” I said in his interview. It does not usually go down to land. It is unquestionable that Mario Salcedo is found aboard a cruise as a fish in the water, so, the few times that he goes down to the ground to take a plane that takes him to his next cruise, when they dock in Miami to verify that Everything is still in order in your apartment or when you have to make efforts with the bank or medical visits. Luckily, except for his problem with balance when Pisa Tierra Firme, the Millionaire Sexagenarian enjoys good health. A key factor for “Super Mario” to follow your adventure on the high seas, given that shipping companies prohibit That a person who needs constant medical care rises on board.

We have a problem with pesticides in agriculture. And a bigger one with the panic they generate

by

Fear is a powerful weapon, and also a double -edged sword. Fear can lead us to caution or paralysis and dividing line is not necessarily wide. In the food sector this is especially true: Food is a pillar of our healthbut there are hardly any foods or additives that have not been at one time or another affected by some form of collective fear. A classic protagonist in this context is the pesticides. “People prefer not to know what the lettuce, tomato or strawberry by the BBC. Navarro de Castro is a sociologist and diploma in rural extension and development and in its latest novel, greenhouse planet, addresses The issue of the agricultural system That feeds us. Contemporary agriculture is difficult to understand without use of pesticidesnatural or artificial chemical compounds destined to poison arthropods and other animals that could threaten plantations. These compounds allow the integrity of our crops not to depend on periodic pests or that every year we lose a fraction of our production consumed by these animals. Pesticides raise two big problems. The first, about human health: if these compounds end up in our food chain, they can mean a risk to our health. The second risk is environmental: these compounds can end up extending beyond our orchards and greenhouses, causing damage to the environment. The possibility of consuming toxic substances in our foods scares. It is normal. But would you really be justified to eliminate entire categories of our diet for the fear of pesticides? Perhaps before reaching conclusions it is important to have a notion of the magnitude of the problem. A magnitude that can vary depending on our location: each country has its own legislation when regulating the use of pesticides, but also the ability to assert those laws It can depend on our geographical context. In Europe, the European Environmental Agency (EEA) published in 2023 A report in which analyzed the impact of pesticides in the environment and in our health. They observed, for example, “above the barrier of worrying” in 22% of the points monitored in rivers and lakes of the continent. They also referenced a study published in 2019 in which pesticide residues were found in 83% of agrarian soils in Europe. But the pesticide track is not only still in the environment, but also in our own bodies. In this case, the EEA refers to a study that monitored participants in five European countries between 2014 and 2021. In result: they found indications of the presence of at least Two types of pesticide in 84% of the sample. As the agency explains, the levels detected used to be older in children with respect to adults. The good news, in a certain sense at least, is that the sales of pesticides in the old continent were stable. Threat to health And what consequences can pesticides have on our health? It all depends on pesticide and dose so to talk about impacts. As noted The World Health Organization (WHO), pesticides are “potentially toxic for humans and can have both acute and chronic effects on health depending on the quantity and way in which a person is exposed.” The people most exposed to these agents are not necessarily consumers, but people with more risk are Those who manipulate themeither in their work as in their homes and orchards, adds the UN agency. The EEA indicates Some of the potential effects on our health. These include cancers such as non-hodgkin lymphoma, ovaries and prostate; neurological problems such as Parkinson and Alzheimer’s diseases; cardiovascular diseases; problems in the development of the little ones; reproductive problems both in men and women; and cognitive problems. Inter alia. The agency also points out that today it is impossible to estimate the degree to which these problems affect the European population. The issue of health impacts on health Still still investigated For experts from all over the world. The obvious question is, is there a solution? Washing the fruits and vegetables that we are going to consume is a simple act that Help reduce our exposure To this type of agents. But They do not solve the problem: This action does not eliminate all pesticides, does not avoid other forms of exposure and fails to reduce its presence in the environment. In Your interview with the BBCNavarro de Castro proposed a simple solution and within reach of consumers. “From the collective point of view, a thousand simple things could be done such as eating seasonal,” acquiring awareness of the origin of each product that we lead to our homes (and our stomachs).

We have a problem with heat in buildings. A Navarra investigation knows how to cool them without air conditioning

by

Every year we repeat the phrase that this has been the year less hot in the coming yearssince it is one of the consequences of climate change. One of the “traditional” ways that we have to refresh in our homes is with an air conditioning system, but poses an economic problem, because the invoices are not paid alone. However, a new Navarro study has managed to find a solution to refrigerate buildings with hardly any energy expenditure. Short. A research team, Formed by Amaia Zuazua Ros from the University of Navarra and Cristina Salazar Castro of the Luredera Technology Center, has developed a project to cool buildings without the need for air conditioning. Under the financing of the Government of Navarra and within the framework of the Navarro R&D System (SINAI)and with the coordination of Aditechthe proposal has sought to boost new passive cooling technologies through modules coated with nanomaterials, designed to eliminate heat from buildings without resorting to electrical systems. The challenge is not less. In the last 30 years, the energy consumption for the cooling of a home is It has tripled. These data, detailed in the International Energy Agency, have highlighted the impact on global electrical demand. For this reason, reducing this consumption without compromising thermal comfort is one of the great challenges of energy efficiency today. The operation. The system is much simpler than it seems. To explain it more easily, the researchers have identified a material that allows to cool the surface of the building, even when exposed to the sun. On the other hand, they have designed a structure to eliminate accumulated heat and thus improve air circulation on the facade by vertical dissipating modules. In addition, they have developed a system to easily adapt to different types of construction. The possibilities. Since the investigation they have detailed that the implementation of these modules in residential and commercial buildings would mean a reduction in energy consumption aimed at refreshing the environment. In addition, in cities with the large amount of solar panels that are being installed and The urban heat island effectthis new system will help mitigate high temperatures from these factors. However, the researchers, who are optimistic, have explained the challenges they have to overcome and how they should observe the long -term application. However, they have added that this technology represents a step forward in the fight against climate change and the design of more sustainable cities. Any other alternative? In the search for sustainable solutions for refrigeration without energy consumption, researchers from different parts of the world are betting on different approaches. An interesting example comes from Indiawhere a system based on recycled clay has been developed. Inspired by botijo ​​technology, this system uses clay cylinders to reduce the ambient temperature by up to 15ºC by evaporation of water, without the need for air conditioning.

China is raising an unprecedented dam where millions of people live. The problem is seismic activity

by

Before finishing 2024 we advanced what was known about China’s last megonstruction. Actually, we could not talk about “another” as if it were something else in a long list, because it is possibly one of the most ambitious projects that are reminded of the nation: a super prey so monumental that would leave The three throats relegated to the background, producing three times more energy than the spectacular structure of more than two kilometers long. Of course, there is some problem. The superpress. It is a reality: China advances with the construction of the Motuo Superpress in Tibetan unprecedented infrastructure project that, if completed, will become the largest hydroelectric power plant in the world taking advantage of an abrupt slope of 2,800 meters, exceeding the capacity of the three throats dam (currently the biggest in the world). Located in The Grand Canyon of Yarlung Tsangpoon the border with India, the dam has aroused environmental, geopolitical and humanitarian concerns, especially due to the lack of transparency of Beijing about its development. Experts warn that the project represents a “water pump” for millions of people in India and Bangladesh. Seismic risks. The Tibet is One of the most seismically active regions on the planetit has been known for a long time because it is located in the collision of the Indian plaque and the Euroasy Plate. In fact, a recent 7.1 magnitude earthquake in Shigatse It caused damage to five hydroelectric dams and the death of 134 people, demonstrating how vulnerable infrastructure in the region is. Although Motuo’s work can be designed to withstand earthquakes, landslides and mud alluds could serve as a fuse and unleash, representing a direct threat to nearby populations. We speak, again, millions of people. This risk is aggravated by the phenomenon of Seismicity induced by reservoirs (RTS)where the weight of accumulated water in large dams can trigger earthquakes. An example is the zipingpu damwhose construction was followed by Sichuan’s devastating earthquake in 2008 which charged 87,000 lives. In addition, sediment retention by the dam could reduce the fertility of the soil downstream, causing erosion in the rivers and coasts of India and Bangladesh. Gran_Cañón Yarlung Tsangpo Environmental impact. The dam too would alter the water and climatic patterns Crucial for agriculture in the region. The Tibet, where Brahmaputra is born, is one of the most biodiverse regions of the world and a key regulator of Asian climate. The construction of the superpress could, for example, alter the monsoon rainfallwith devastating effects for agriculture in India and Bangladesh. In addition, the ecological impact of Chinese megaemblses is already evident in other international rivers, Like the Mekong, where the dams have caused droughts recurring and the intrusion of salt water in agricultural deltas. Impact between the premises and (des) information. It is another leg that must tie the project. The Tibet is under a strong control of the Chinese Communist Party, so the magnitude of the displacement of Tibetans that will require the work is not known. In this regard, Beijing has not revealed details about costs (It is estimated that total investment will exceed 130,000 million euros), The companies involved or the number of people who will be relocated. And if we are guided by other cases in Chinese provinces, protests against hydroelectric projects have been repressedit is suggested that any opposition in the Tibet will be silenced. Geopolitics of a superpress. He Brahmaputrawhich flows to India and Bangladesh, is a vital artery for millions of people. Again, that lack of Chinese transparency has generated distrust in New Delhi and Daca, whose scientists have demanded access to hydrological data to evaluate the risks of the work. India, meanwhile, Fears China use river control as a geopolitical weaponrestricting or diverting the flow in case of conflicts. Thus, and in the face of uncertainty, some Indian officials have proposed an alternative: Build a dam in a Brahmaputra tributary to counteract possible flow reductionsalthough this solution does not seem ideal and could also harm the ecology of the region. Imminent risk. Nikei had this week That the possibility of a catastrophic collapse is not a simple speculation. China has suffered hundreds of dam failures throughout its historyincluding the worst disaster ever registered: The collapse in cascade of the Banqiao dam And another 61 dams in 1975, an event that caused 85,000 direct deaths and displaced 11 million people. Even The three throats dam was on the verge of collapse in 2020endangering 400 million people. Therefore, if a strong earthquake hit the region and cause the rupture of the superpress, Millions of people in the Brahmaputra Valley in India and Bangladesh could be affected by catastrophic floods, aggravating. In addition, geopolitical and humanitarian tensions in the region. If you want also, it is feasible to think that with this mega -Obra, China would not only reinforce its control over the water resources of Asia, but also converting Brahmaputra into a geopolitical weaponincreasing their pressure capacity over their neighbors.

A new estimate of the Hubble constant delves into the problem

by

The “Hubble voltage”It is one of the greatest enigmas of contemporary cosmology. It refers to the fact that the increasingly precise measurements of the speed at which the universe disagrees expands. And not We have a lot of idea of why. Faster Now a new study has led Hubble tension to a new maximum. The work indicates that the observed acceleration of the universe is greater than what today’s physical models could explain. Theory and practice. There are two forms of measure the expansion of the universe. The first is based on the cosmic microwave background (CMB), a remaining radiation of the process that we know as big Bang. By measuring fluctuations in this background, it is obtained An estimate of the expansion speed of about 67 kilometers per second by Megaparsec (km/s/mpc), an expansion speed according to what the generally accepted cosmological models estimate. On the other hand, observations of the nearest universe tell another story. The cefaids are stars whose brightness is inversely related to the frequency with which they press. This allowed astronomers to create a “cosmic ladder” calibrating step to step the measurements of distances to increasingly distant objects in the cosmos. The problem is that this other measure estimates a significantly higher expansion speed: about 74 km/s/mpc. From tension to the crisis. The new study has deepened this discrepancy. The new measure based on the “cosmic ladder” has estimated an expansion rate even greater than the average of the previous measurements: about 76.5 km/s/mpc. This has led the team to point out that “The tension has become a crisis.” The step that was missing. The team responsible for the study created its own “cosmic ladder” from the DESI collaboration data (Dark Energy Spectroscopic Instrument). This instrument monitor about 100,000 distant galaxies thanks to 5,000 robots with fiber optic sensors that monitor space. The team responsible for the study had to “anchor” these data to our immediate vicinity, that is, put the first step of the “cosmic ladder” with which to measure the changes observed by DESI in its follow -up of these galaxies. To do this, he resorted to the cluster of the comma, one of the galactic clusters closest to the Milky Way. Supernovas To measure the distance to this cluster, the team turned to the light curves of 12 IA type supernovae located within your own Cluster. This type of supernovas shines in a very predictable way, so its apparent brightness gives us a good measure of its real distance. The details of the process can be consulted In an article Posted in the magazine The Astrophysical Journal Letters. The search continues. These types of intrigues generate great interest in the scientific community since it is through cracks in ancient models that are usually opened by the discovery of new theories. “It’s exciting,” explain those responsible for the study. But the truth is that, for now, we have few clues that allow us to solve this issue, either through substantial changes in contemporary models, either through changes in the paradigm.

Elon Musk says he will rescue the two astronauts stranded in the space at Trump. The problem is that

by

A incendiary message. “The president of the United States has asked Spacex to bring the two astronauts stranded at the International Space Station as soon as possible,” Elon Musk wrote In his profile of X. “It is terrible that the Biden administration has left them there for so long.” After 20 minutes, more than one million people have seen the message, which Musk apostilled answering “true” to the following answer: “The hatred they had was greater than their desire to rescue those astronauts.” A little context. In June 2024, two astronauts arrived at the International Space Station aboard the Starliner spacecraft, Boeing’s alternative to the Crew Dragon of Spacex. The ship had to spend a week in orbit before returning to Earth, but A failure in the propulsion system During the first leg he made three months undergoing And finally I would go empty. Elon Musk’s X messages about astronauts Elon Musk lies. No one will be surprised at this point that Musk publishes propaganda in his X profile, but the message misrepresent the reality in a particularly fantasy way. While it is true that astronauts Butch Wilmore and Suni Williams are still in space since June, they are not stranded. SPACEX CREW-9 MISSION took off in September 2024long before Trump assumed the presidency, with two empty seats to bring them back. So why do they continue in the ISS? It was the plan provided by NASA. Wilmore and Williams were reallocated to the CREW-9 mission and became part of the permanent crew of the International Space Station. Williams is, in fact, the commander of expedition 72, and He has just taken a space walk As part of your tasks. That NASA did not ask Spacex to look for them immediately has nothing to do with the hatred of Musk, but that there was no crew dragon to immediately available. The most logical solution was to get two astronauts out of the next round trip (the CREW-9 mission) to leave two free seats. And now what? The return of the CREW-9 mission is scheduled for the end of March 2025. So far, the expected thing was that Wilmore and Williams return along with their mission partners, the American Nick Hague and the Russian Aleksandr Gorbunov, in March or maybe in April. But Musk’s message suggests that perhaps his return goes ahead. As for the Starliner, NASA canceled the flight that had hired Boeing By 2025. The two astronaut rotations of this year will be in charge of Spacex while Boeing continues to analyze what could fail in its first manned flight and how it plans to solve it.

Deepseek is the fashion model. The problem is that nobody knows very well what you are doing with our data

by

If you are a user of Chatgptit is likely that in the last week you have tried Deepseek. He Chinese ia chatbot It is so promising that It has become a serious threat to many of the American technological giants. Not only is it an open source proposal that can work very well at home (in a certain hardware), but also has a free online version that, at least for the moment, allows unlimited consultations. There is also one Payment API whose rates are very competitive. When we use chatbots like Deepseek we usually share a lot of information. These tools have become allies when planning vacations, summarizing documents, making budgets, analyzing images, among other things. Their language models swallow every word that we introduce to give us the answers we are looking for or an approach that we can refine to Prompts. What do they do with our data? Now, after the initial crush of discovering a new application of ia, let’s ask ourselves What happens to our data. Do they disappear after being processed by the model? Do we give them perpetuity to a company that we don’t even know? Are they stored as a treasure for training future iterations of the model? Certainly there are many questions, many, but they are not completely new. We already asked ourselves many of these questions when Chatgpt achieved popularity. Perhaps we did not ask ourselves the questions, but several European regulators were asked, which forced the company led by Sam Altman to make some changes to continue operating in certain countries of the block. Deepseek is the new star, and sooner or later these questions should appear on the scene. In the midst of so many questions there are some certainties: Deepseek collects a huge amount of data. This is probably not a surprise for some, but for others who have just started using chatbot. To have more clarity about the PRIVACY PRACTICES OF THE CHINISH COMPANY we can consult its page of Privacy Policy. Let’s start at the beginning, Hangzhou Deepseek Artificial Intelligence Co., Ltd. and Beijing Deepseek Artificial Intelligence Co., Ltd. collect information on the profile of users, such as username, date of birth (if applicable), address of email and/or telephone number and password. Our chats also collect, that is, texts, audios, charged files, comments, history. Everything goes to these companies. Suppose you have a question about Depseek and use the contact paths to talk to them. Well, the aforementioned organizations will also collect all the information you send. From identity or age tests, comments or consultations about the service. Everything mentioned so far is within a category called “Information you provide.” Within the range of information collected by companies behind Depseek we find another category called “automatically collected information.” Here they are made with our device model, operating system (and the language of the), IP address, cookies and diagnostic data and performance. They will also capture the keys of keys, and everything will be associated with a device ID and a user ID. It is not possible to quote our data, but there are no doubt that they are valuable. One way to measure its value is to size everything they drive. First, Depseek uses the data collected to train your AI models. Companies also talk about “interactions supervision”, and at this point we are not sure if there are humans analyzing conversations. In the documents of the companies we find other interesting information, such as that “review the entries and exits of the user and other information to protect the security and well -being” of the community. They also collect data to comply with legal obligations, to “carry out public interest tasks” and to notify changes in services. Later we will see where the data of the millions of Deepseek users are stored. The data collected by Depseek does not stay in Deepseek Deepseek says in its privacy policy that you can share the information collected from all categories indicated above. We go in parts. First, we can mention corporate group entitiesthat is, actors that are under the umbrella of organizations that control Deepseek. But there is more. They can also be sent to “advertising or analytical partners.” Possibly remember that paragraphs above we point out that the information collected is labeled with a device ID and a user ID. Well, these identifiers are usually very useful to track user activity and cross it with that of other platforms. At this point Depseek mentions that you can use activity from other sites and services, but in some jurisdictions. It is not clear how this will be applied in the European Union. Deepseek also explains that they can share the information collected with “the agencies responsible for enforcing the law, Public authoritiesthe head of copyright or other third parties if we believe in good faith that is necessary. ” In other words, they can give this data to the government. While this occurs in almost any jurisdiction, we must pay special attention to China, which has been involved in several controversies in this regard. There are numerous investigations that point against the Chinese Communist Party (PCCH) and Laws of the People’s Republic of China for forcing the technology companies of their country to provide data to relevant information. A document of United States National Security Department points out that the Government urges companies to install rear doors To help in operations to maintain national security. One of Tiktok’s conflict points It was precisely the one we just mentioned. The data of the Americans were apparently exposed to foreign actors. To address this concern, Bytedance, the social network matrix, An agreement with Oracle arrived To store the data of the United States users in their territory, also submitting them to legislation the North American country. The data collected by Depseek is stored on servers in China. Besides, We have spoken a lot about how strict the regulation towards technological ones in the European Union.

OpenAI’s rival company is taking steps to address the problem

by

The latest innovation in the field of artificial intelligence (AI) It comes from China and is called DeepSeek. This chatbot, which competes directly with OpenAI’s ChatGPT, has gained notable popularity in recent hours. Many users highlight its capabilities, and some even wonder if it is worth investing in similar tools. However, it is not all good news. DeepSeek, the company behind the tool of the same name, says it has suffered a cyberattack. According to the interface itself, these are “large-scale malicious attacks” that have impacted its services. The nature of the incident is still unclear, although there are indications that point to a distributed denial of service (DDoS) attack. The measure the company has taken to address the problem has been to temporarily limit registration of new users. This means that people who want to use the AI ​​chatbot for the first time will likely not be able to register, at least on the first try. DeepSeek itself recommends trying again if you are not successful. Users who were already registered on the platform should have no problems accessing it. However, in our tests we observed that the chatbot took longer than usual to respond. It should be noted that, in the last few hours, the service has remained inaccessible for some users, as indicated by the DeepSeek status page. In development.

We knew that US Big Tech had a problem with the costs of their AI. DeepSeek has just shown to what extent

by

DeepSeek is the new darling of AI. This family of models, developed by a Chinese R&D laboratory of the same name, has achieved what seemed impossible: compete with the OpenAI or Meta models and do so, according to them, at a much lower cost. Is that true? A development 18 times cheaper than GPT-4. The Chinese startup released DeepSeek V3 671B at the end of December 2024. Its gigantic model was trained in just two months with a budget of 5.58 million dollars according to SCMP and analysts cited in Financial Times. Its performance is comparable to OpenAI’s GPT-4, but the latter cost about $100 million to develop according to Sam Altman. That’s almost 18 times more if we take into account both the data revealed by SCMP and Altman’s estimates. Comparative cost of the main chat and reasoning models today. DeepSeek’s price is incredibly lower than its competitors. Data: DeepSeek, OpenAI, Anthropic, Meta. Amazingly cheap. The cost of DeepSeek’s API is incredibly low when compared to its competitors. If we take the data from DeepSeek, Goal, OpenAI, Google and Anthropic It seems to be clear that the cost of using DeepSeek through its API is much lower than that proposed by its rivals. We have included the cost of GPT-4o mini which seems to be the only one comparable, but its performance is much lower than DeepSeek V3. DeepSeek V3 is superior to most of its competitors, although it is true that Meta has released for example Llama 3.3 in recent days and that comparison varies frequently. And it is (theoretically) superior to all. As they point out on RedditDeepSeek V3 prices are promotional: starting February 8 they will be $0.27 per million input tokens (almost double) and $1.10 per million output tokens (almost four times more) . This makes the comparison somewhat better for the competitors, especially for Llama, the only one that can compete in cost although the Chinese model is superior to that of Meta (and almost also to the rest in many metrics) according to the benchmarks carried out in DeepSeek. DeepSeek also “thinks” cheaper. The cost comparison is not only in favor of DeepSeek in the area of ​​traditional chatbots, but also in the area of ​​reasoning models. According to its internal benchmarks, the spectacular DeepSeek R1 It is significantly superior to OpenAI’s o1, but using the o1 API costs 27 times more than that of DeepSeek R1. Hallucinatory. Price drop in sight. As expert Ethan Mollick points out, the market will adjust to these DeepSeek-driven price drops fairly quickly. According to their estimates, the cost of a GPT-4 level AI was reduced 1000 times in 18 months, and a 95% drop in the price of the reasoning models, which right now are clearly higher than the AI models behind ChatGPT, for example. a chinese tsunami. The launch of the DeepSeek models is a great little revolution for all types of developers of AI-based solutions: they now have access to much cheaper models that are comparatively equal to or superior to those of the competition. This puts their rivals in a lot of trouble, and we will see how they react. Good news for users. The truth is that for us, the users, as well as for the developers, this is great news, especially because these prices make access to these functions incredibly cheaper. The market has been following this trend clearly, but DeepSeek has made the jump in cost reduction suddenly drastic. Image | Xataka with Freepik Pikasso In Xataka | OpenAI prepares a PhD-level AI.

Malaysia came up with the idea of ​​painting its roads fluorescent to illuminate them at night. The problem was the price

by

In February 2024 we saw that the continuous line of a good part of the A-355, one of the roads with more accidents of Spanish territory, dawned with a thick continuous red line. It was a pilot measure by the DGT to highlight the prohibition of overtaking on that road. A few weeks earlier, a similar program was developed in Malaysia: repainting the road markings of certain roads with a photoluminescent paint. Not even a year has passed and it seems that they will not continue painting. The reason? It is too expensive, which has raised the question of… and they hadn’t thought of that before? The pilot. In mid-November 2023, the Government of Malaysia advertisement the launch of a pilot program that aimed to highlight the lines of certain roads. Using photoluminescent paint with the ability to glow at night. The authorities commented that these initiatives were suitable for dark areas that lacked public lighting. The lines shine for 10 hours and, in case of heavy rain, they also give off a certain shine that helps make them more visible, allowing drivers to stay in their lane. The images leave no room for doubt: it looks much better than the traditional white line, also better than reflective indicators. The project attracted attention. Initially, only 245 meters of road were painted at one intersection, representing about 490 meters of road markings, but other states began to carry out their own tests. Almost 20 times more expensive. The problems came practically from the beginning. The Malaysian Ministry of Works already warned that they were going to be very attentive to the results of the pilot program and the ability to paint on other roads, since the price of the new paint could be a problem. And so much so that it has ended up being an inconvenience. From the Ministry of Works reported that conventional paint costs about 40 ringgit per square meter, about 8.65 euros. Photoluminescent paint costs 749 ringgit per square meter, more than 160 euros. It costs 19 times more per square meter. Putting on the brake. Despite the enthusiasm with which the population received the measure, Malaysia’s deputy labor minister, Ahmad Maslan, commented a few weeks ago that it was not likely that they would continue painting. “The cost is too high, so we probably won’t continue with glow-in-the-dark lanes,” stated. It is curious when, months before, 31 roads had been identified that could have received this type of paint. Maslan stated that the tests did not meet the expectations of the ministry’s experts, without giving further explanations. Questions and suspicions. This is part of the eternal debate about priorities, budget and security, since we must remember that the areas that were going to receive this type of paintings are wooded and lack lighting, making it dangerous to travel through them due to interactions between humans. as by the action of animals crossing each other. And, evidently, the news has raised suspicions of corruption in local mediawith users who wondered if they didn’t know all this before starting the pilot project, what are those expectations that the painting has failed to meet… and that someone will have filled their pockets with the initial contract.
