Let’s tell you How to solve the problem of some apps not showing on Android Auto. Because it can be frustrating to start your car and realize that apps are missing from the screen that were there the day before, especially if some important ones disappear, such as music ones. Therefore, we are going to tell you what things can you look at one after the other, because these problems are usually due to specific things such as the launcher configuration, permissions, or even battery restrictions or if you are left halfway after installing an app update. Therefore, we are going to review the solutions one by one. Check if the app is hidden The first thing you have to do is check if you have the app activated on Android Auto. You have to do this in Android, where you access a list of your mobile applications and decide which of them are shown or not in Android Auto when you connect it to the car. To do this, you have to enter the Android Auto settings on your mobilewhich is usually within the section Connected devices. and once inside, look for the option to customize the applications menu. You will go to the list of apps, where those that are selected will be seen in the car, and those that are not selected will be hidden. Check that Android Auto is updated Many times we don’t worry too much about updates because we assume that they happen on their own. But if Android Auto is not updated or the associated services either, there may be strange behavior or errors. Therefore, it is advisable to check Android Auto in Google Play, Google Play Services and the phone’s system update itself, if it has been pending for a while. Make sure everything is correctly updated. View an app’s battery restrictions Many manufacturers implement different systems to manage the battery and save consumption with their applications. There are options for restrict the app from being used in the background to save battery, and if one of your apps has it, it simply won’t be seen in Android Auto. To find out this you have to enter Settings and go to the section Applications to display the list of all installed ones. Now click on the one you want and you will enter its settings, where you can click on the battery section and check if it has permission to run in the background. See if the app has the permissions it needs When you use an application for the first time, Android asks you to give it permissions to access your device’s hardware, such as the microphone or location. If you have restricted these permissions to maximize privacy, the app may not work properly on Android Auto. Here, you have to enter your mobile settings, click on Applicationsand access the list of apps. Once inside, click on the one that is affected and does not appear or does not work well in Android Auto. When you do, review the following permissions: Notifications. Microphone, if it is a calling or voice messaging app. Location, if dependent on real-time services. Files and multimedia content, in some audio or navigation apps. Sometimes it could be a problem with the app There are times when the problem is not with Android Auto or any configuration, but with the application itself. Compatibility may have been temporarily lost after a poorly resolved update. To check this, you can take the following three steps: Check if the app is updated in the Google Play Store. Go to Google Play and see if it is still listed as compatible with Android Auto. Check if another app of the same type does appear, to rule out that the problem is general. With this you will be able to know if Android Auto is displaying the menu incorrectly, or if the specific application has simply changed something and no longer works as well in the car system. You can reinstall the application Turning it off and on again has been the great solution for many software problems for decades, and you can try it on your Android mobile. Another final solution is reinstall the application that is giving you problems. To do that, simply uninstall it and reinstall it.

Australia has a problem: extremely boring and monotonous roads. And it also has a solution: sign trivia

by

If you drive on Australian roads you may come across unusual signs and we are not talking about the kangaroos warning (that also), but the one that warns you that you are about to cross the “90 Mile Straight“, a stretch of almost 150 kilometers in a straight line that means spending just under two hours without turning the steering wheel. Or a sign that directly throws you a random question typical of Trivial. The objective is that your brain does not disconnect because on such a monotonous route, boredom can be lethal. In fact, Australia has some of the most dangerous roads in the world and it is not because of their poor condition or their dizzying curves, quite the opposite: they are too long, too straight and too empty. So the country is exploring different solutions to avoid this potentially deadly drowsiness. Boring Australian roads. All of these roads have decent pavement, a predictable layout, a landscape with little variation and little traffic, a recipe for disaster: The Eyre Highway takes the cake: it connects Western Australia with South Australia across the plain Nullarbor Plain (which takes its name from the Latin: treeless) between Balladonia and Caiguna: 200,000 square kilometers of limestone land with hardly any vegetation or hills. A 146.6 km straight line without a single curve that you have to travel at 110 km/h (the legal limit in most of the country). After the Saudi Arabia Highway 10is the second longest straight road in the world. The Stuart Highway It crosses the center of the continent from north to south, from Darwin to Port Augusta, traveling more than 2,700 kilometers inland on a fairly simple route that also crosses the Northern Territory. There it has large stretches through northern areas with distances up to 252 kilometers Between gas stations, temperatures of up to 45 °C are reached and a landscape monotony that has little to envy of the Nullarbor. In fact, one of the roads with the highest rate of fatigue accidents in the country, according to the Australian government. The Barkly Highway It connects Queensland to the Northern Territory via the Barkly Tableland, a flat, arid plateau where the road stretches almost straight for hundreds of kilometres. The extreme heat, the total absence of shade and the sections without signage or rest areas make it a minefield for those who travel through it. The Flinders Highway Also in Queensland it runs through the interior of the state for more than 800 kilometers. It connects Townsville with the interior through a repetitive landscape, with little traffic and long distances between towns, the ideal breeding ground for boredom. At night it is even worse. The danger of road hypnosis. The highway hypnosis or white line fever is more than just being bored and drowsy: it is an altered mental state that allows you to continue driving, responding to basic stimuli and maintaining speed, but without being aware of what you are doing. Simply put: put your brain on automatic mode. science has an explanation: Flat, straight roads with little landscape variation produce a chronic deficiency of sensory stimulation, reducing alertness to dangerously low levels, causing drowsiness and inattention. This study on the phenomenon explains that cognitive fatigue reaches its peak just 20 minutes after entering that monotonous environment, much sooner than it might seem, even for those who are driving. When the brain warns, it has already been on autopilot for a while. The consequences can be tragic: unconscious speed increases or a minimal reaction capacity that already causes havoc. In Australia, fatigue while driving is four times more likely as a cause of this road hypnosis than drugs or alcohol. In Queensland, it accounts for 20 to 30% of road deaths. A15, Queensland. Via Google Maps Trivia on signs. The solution that Australian authorities have been implementing for years is so simple that it is shocking: posters with a question and answer game. As you enter one of those boringly dangerous areas, you come across a yellow sign that warns: “Fatigue Zone. Trivia Games Help You Stay Alert” (Fatigue zone. Trivia games to help you stay alert). From that moment on, you will find signs scattered along the route several kilometers away with a question and his corresponding response. Example: Question: Who was the first Premier of Queensland? Answer: Robert Herbert. And so on. The cognitive mechanism is exactly what science describes: introducing an unexpected and irrelevant stimulus for driving that forces the brain to come off autopilot. So the driver has to read, process the question, remember and, if there is a co-driver, even debate the answer. And then wait to see the solution a little later. A simple but effective way to activate the mind. Each question and answer is glued to the panel and secured with a padlock, allowing them to be renewed. And does it work? Well, probably yes, but no one has rigorously measured it. However, in theory the mechanism is supported by neuroscience. Professor Narelle Haworth, Director of the Center for Accident Research and Road Safety Queensland, endorses his presence: “Always doing the same thing, without much stimulation, causes a decrease in alertness (…) The idea of ​​trivia games on the road is to keep drivers more attentive… perhaps a passenger who knows the answer will start a conversation.” But Haworth herself acknowledges that although the objective is in line with road safety research, there is no study that has specifically analyzed the impact of the signs. In addition, it has its limitations: the signs lose effectiveness with those who travel the same route frequently and already know all the questions. And obviously they have a quite common risk in these times: Someone might think to look at their cell phone to look for the answer. And in any case, it does not replace rest. Triple animal sign.

If your hard drives disconnect on their own, an underpowered USB Hub may be to blame. With these you won’t have that problem

by

If you usually use a hub to connect hard drives, mice, keyboards and other accessories or peripherals, perhaps at some point it has happened to you that they disconnect randomly. That’s especially worrying with hard drives, because you can lose data. Today we are going to tell you why the problem is not the hard drive, but surely the hub USB you have. The price could vary. We earn commission from these links How does a hub Hub without external power. The hubSpeaking of models that do not require external power, they are accessories that generally have fairly low prices, although it depends a lot on the brand. They act like port multipliersince connecting them to a single port on the computer (generally USB-A or USB-C) allows us to connect two or more devices to the hub. They are usually quite cheap, small and there is a wide variety to choose from, with different formats (elongated, square and even round). To use them you only have to connect them to a USB port on your computer, without the need to also connect them to a power outlet. AND here is its main limitation. The energy required to use it comes directly from the computer, so the power will be limited to what the port offers. Furthermore, the maximum power is always divided by the hub (so that it can work) and the number of devices that we connect. To give you an idea, a standard USB 3.0 gives 900 mA. A mechanical hard drive can require almost all of that to boot. If you add a keyboard with lights, the system collapses. How does a hub with external power Hub with external power. The hub with external power they are less frequent, more expensive and often larger. Here we can identify the hub assets, which are usually cheaper, and Docking Stationwhich are larger and come with more ports, including some video ones. With this type of hub We are not so limited to the power that the computer’s USB port can offer. In practice, this means that in many cases the power does not have to be divided when connecting two or more devices, although there are exceptions: some USB ports of the hub Active devices require so much energy that they prioritize these ports, something that we can see in those USB-C (Power Delivery) that are aimed at charging devices such as mobile phones compatible with fast charging. It is worth mentioning that the hubs assets come with a USB-C PD (Power Delivery) port. They don’t come with a transformer, but if you connect the laptop charger to them, they become “powered.” And… what are they for? Both the hub assets like Docking Station They are ideal if you are looking to connect devices that require high power, such as mobile phones, monitors or hard drives and SSD drives. By way of differentiation: It’s a hub passive if: It just has a short cable coming out of it and nothing else. It’s a hub active if: It has an extra port that says “DC 5V” or “USB-C Power Delivery (PD).” It is a Docking Station if: It is large, heavy, has its own power brick (like that of a laptop) and has video connectors such as DisplayPort or several HDMIs. The good and the bad of both options, face to face Hub without external power hub with external power THE GOOD 🟢 They are cheaper, more compact and lighter. They offer better stability when connecting many devices and usually have a greater number and variety of ports. THE BAD 🔴 The power is limited to what the computer’s USB port offers, so you may experience power outages in certain cases. They are more expensive and tend to be larger and heavier. Ideal for: Keyboards, mice, microphones or flash drives (pendrive). Mobile phones with fast charging, hard drives and SSD drives and monitors. We do the math to see which one can compensate you more. Both options have their positive and negative points, so the choice lies in how we are going to use them. If it is still not completely clear to you, let’s see it with an example. If you want to use a hub sporadically because you are not going to connect many devices at the same time, it may be worth it to buy a hub without external power. Actual use: Let’s say you want to connect two low-power devices. The accounts: You save between 70 and 80 (or more) euros between the cost of a hub without external power and another with external power. Also, if you chose this second option, you would not be squeezing it, since you are going to connect low-power devices. So? If you want to connect a mouse and keyboard (because they are wired or because you want to recharge them) and you still have a free USB port on your computer to connect a hard drive, this type of hub It can serve you very well. However, if what you want is to connect several devices, low or high power, and you do not have any more free USB ports on the computer or they are in an area that is not easily accessible to use them, it will be more useful for you to go for a hub with external power. Actual use: Let’s say you want to connect many devices to the hubsome need more and others less power. The accounts: You pay more for this type of hubbut it allows you to connect practically any device. So? You can have a greater number of connected devices (depending on the hub), and it will give you “the same” what to connect, whether it is a keyboard or a hard drive because it will offer a stable connection. Also, as a utility, if you have the computer under the desk or in some area that is difficult to access, you will not have to bend down to … Read more

It’s a huge problem for AI.

by

The United States (like Europe, China and the giants of the Middle East) are in the midst of a real estate race: that of data centers. Nobody wants to be left behind AI race and, for that, they need gigantic enclosures in which to train it. The big problem is that these facilities They consume a lot of energyand there China seems to have the upper hand facing a United States that does not have the best face. In fact, it is estimated that half of its data centers scheduled for 2026 will be delayed not canceled. And it is something they cannot allow. It’s not a money problem. Meta, Amazon, Microsoft and Google are going to pool more than $650 billion this year to build artificial intelligence infrastructure. To put it in context, It’s more than the Apollo program cost. that took us to the Moon for the first time or to the great railway expansion of the 19th century. It is private capital that is doing the trick, but although the State does not pay the main bill, it facilitates operations and influences the pace and deployment of massive data centers through regulatory decisions, permitting and energy planning. And the latter is vital. The tyranny of 24/7. My partner Alba coined that term a few days ago to describe the current situation in which companies focused on AI find themselves. AI is intended to help us optimize our electricity consumption by the 2030s, but right now it is only achieving one thing: collapsing the traditional grid. This technology needs a lot of energy and, furthermore, constant, which is causing collapses in the network. The estimate is that the energy consumption of these data centers will increase by 175% between now and 2030. And not only consumption: Google’s emissions have increased by 48% in the last five years and Microsoft’s by another 31%. They were two of the most committed companies with ‘net zero’ by 2050. The other bottleneck. With this in mind, and knowing that the industry is devouring resources such as NAND memories To feed the AMD and NVIDIA platforms used by hyperscalers, we must talk about the other bottleneck in the sector: the energy. On the one hand, there are the plants themselves and we already know that companies have plans for private nuclear plants, gas is booming and coal is used in peaks of demand. On the other hand, there is the equipment that is installed in the data centers themselves. We are talking about transformers, switches, dissipation equipment and batteries. Panasonic is one of the largest manufacturers of batteries for racks of data centers. They are “packages” of batteries that are inserted between the equipment so that, in the event of a blackout or maximum demand, they provide specific energy support. A few days ago they commented that its annual production had already been soldbut the problem is that orders keep coming. Bad forecasts. And there is that bottleneck that we mentioned. As they point out in Bloombergthere are analyzes that already suggest that half of the data centers planned for the United States throughout 2026 will be delayed or canceled. It will be a blow to an industry that cannot stop because there is a lot of money at stake (and even more so the year Anthropic and OpenAI want to become public companies) and where they compete against a China that does not seem to take its foot off the accelerator. The solution is to electrify the grid using renewables, but the problem is that these solutions can provide constant energy, but they are not the best to provide a lot of energy during peak periods. workouts. Large batteries would be needed and, with the parallel rise of electric cars, there are none. The Wood Mackenzie analyst group points out that the United States “does not have enough capacity to stand on its own, so its companies are forced to go to the export market.” Geopolitical paradox. And therein lies the problem. The United States and China are immersed in a technological war, but also a commercial one. This makes it difficult for American companies to buy what they need from the Chinese industry, which is what leads the way in batteries and solar panels. Jensen Huang -CEO of NVIDIA- already commented a few months ago that the international conflict was fine, but that there was no need to be short-sighted and they had to take advantage of what China has to offer. The reality is that data centers are estimated to consume up to 12 GW of energy in 2026 in the United States alone, more than ten million American homes need. And, although the electrical infrastructure represents less 10% of the total cost of a data center, it is impossible for the facility to start operating without it. Now, The US has room for maneuveranother thing is that they activate the levers.

The Tax Agency does not want you to use ChatGPT for Income. The problem is that their alternatives are worse

by

The general director of the Tax Agency, Soledad Fernández, has opened the Income 2025 campaign with a clear message: do not use ChatGPT to make your declaration. “With how much the Tax Agency team has dedicated themselves to providing the best help and assistance tools, I wouldn’t risk doing it with ChatGPT,” he said. The warning has a certain meaning. The language models They can hallucinate, they do not have access to your real tax data, and asking them to manage your return involves passing them personal and financial information that ends up stored on private servers. The risk of error (and sanction) is real. That said, there are more nuances. Why is it important. The Treasury notice comes at a time when millions of Spaniards are looking for any shortcut to avoid one of the most tedious procedures of the year. If the official answer is “trust our tools”, the logical question is: are those tools really up to the task? Between the lines. What the Treasury does not say is that the underlying problem is not ChatGPT: it is that the Spanish tax system is opaque enough that using an AI seems like a reasonable solution. If millions of citizens are tempted to delegate their declaration to a chatbot, it is because something has failed before. The complexity of personal income tax (with its regional deductions, its cases of ascendants and descendants, its special regimes) is not an accident of design. It’s the design. The current situation. Treasury has presented improvements in Web Rental for this campaign: more access to data capture windows, greater interaction between sections and better information on subsidies. It has also improved its app. And it maintains the traditional channels: The plan “We call you“starts on May 6 (appointment from April 29). In-person attention in offices, from June 1. They are real advances, but gradual. Renta Web continues to be a platform that requires prior knowledge to navigate with ease. The Treasury virtual assistant resolves generic doubts, but not specific cases. Yes, but. The alternative that remains for those who do not master taxation is to pay a manager. A service that has a cost that not everyone can afford, and that turns a right (understanding and managing your own declaration) into something that must be outsourced. It’s the equivalent of IKEA selling its furniture without instructions and then complaining that people look up videos on YouTube to assemble it. The big question. The Tax Agency also assures that it does not use AI in the processing of files or in extensive control, and that its risk analysis systems “cannot be considered AI in the strict sense.” Although it leaves the door open for its future use. The question they do not answer is another: if AI is good enough for the Treasury to study it internally, why can’t it be part of a solution that helps the taxpayer from within the system, with their own data and with legal guarantees?

Artemis II has a toilet that evacuates the astronauts’ urine into space. The problem is that it has frozen

by

The Orion capsule toilet It is being one of the most commented topics of Artemis II. It is no wonder, since it greatly facilitates the life of the astronauts who are on their way to the Moon. However, if it continues to generate conversation after the launch, it is no longer because of the novelty, but rather because of the incidents it is causing. The last of them has been so important that it has even forced some special maneuvers to be carried out with Orion. Background. Until now, no spacecraft had anything resembling a bathroom for astronauts. Yes, there are options in long-stay facilities, such as the International Space Station. However, there was no way to evacuate during space travel. The astronauts of the Apollo missions, for example, had to use something similar to a condom for urine and a kind of diaper with a hole for toilet paper in case they wanted to do major water. Luckily, the Artemis II astronauts They have a more advanced system. There is no room for so much urine. The Orion toilet uses a type of hose attached to a funnel that, through suction, draws urine into a tank. Thus, the problems of microgravity are solved. On the other hand, this tank has direct contact with the exterior of the ship, in such a way that the urine, once it is full, is released directly into space. urine slushie. Since the journey of the Artemis II astronauts began There have been some problems with the capsule bathbut almost all of them have been solved. Unfortunately, there is another one that is being more difficult to solve. And the low temperatures outside are freezing the urine, so it cannot leave the tank. Maneuver changes. Faced with this problem, it was decided to maneuver the capsule in such a way that the tank and pipes were exposed to the Sun for as long as possible. Thus, the urine should thaw and be released without problems. It wasn’t enough. Unfortunately, although this measure seemed to be useful at first, sun exposure is not enough to have liquid urine at all times. It spends a lot of time frozen, so for now, astronauts are having to put their urine in bags and store them, exactly the same as with feces. With the latter it was already established that they would be stored and taken back to Earth, but with urine the simplest thing would have been to let it flow through space. But for now it’s not an option, so these bags will have to take up some extra space on the ship. Ultimately it is good news. According to statements by the deputy director of the Orion program for NASA, Debbie Korth, collected by Ars Technicathe performance of the capsule in general is being remarkably good. The good development of all the ship’s systems has pleasantly surprised the engineers. Therefore, the fact that the biggest headache for the ship’s crew is that their urine freezes is still good news. It would be much worse if some vital system failed. In that case, no one would notice the capsule bathroom. That everyone is paying attention to him is also a triumph.

Chile has the lithium necessary to save the world from fossil fuels. The problem is that you are extracting it blindly

by

The world desperately needs to move away from fossil fuels. To achieve this, electric vehicles and large renewable energy plants require a vital component for their batteries: lithium. This global emergency has set its eyes on one of the most inhospitable and fragile places on the planet, the Atacama Desert in Chile, which is home to about 25% of the world’s reserves of this mineral. But this “salvation” has a dark side. As deep research reveals published by MongabayChile is accelerating the blind exploitation of its salt flats. Under the institutional promise that this mineral will be the “new salary of Chile”—as It was defined by former president Gabriel Boric by promising wealth with strict environmental respect—the reality in the territory is diametrically opposite. The productive desire is crushing the socio-environmental knowledge that is required to avoid destroying the same nature that, ironically, the world is trying to save. The pact that seals the future. To capitalize on this demand, the Chilean State launched the National Lithium Strategy (ENL)seeking to consolidate the country as the undisputed leader of this market. In this context, an unprecedented mining agreement was forged. According to The Confusionthe state mining company Codelco and the private giant SQM sealed a historic pact to extract lithium in the Salar de Atacama until 2060 under a new joint venture: NovaAndino Lithium. With the aim of avoiding the local resistance that usually paralyzes these megaprojects, the agreement included an unprecedented governance model. This scheme promises the Atacama indigenous communities (the Lickanantay people) million dollars annually in profitsseats at dialogue tables and power of environmental oversight. A model that the industry celebrates as the standard for future “green mining”, but which in the territory has lit a fuse with unsuspected consequences. The disproportion of 33 to 1. Promises of environmental balance crumble when looking at the fiscal wallet. The figures are devastating: for every peso that the Chilean State invests to protect the fragile ecosystems of the salt flats, it allocates 33 to promoting productivity and mining technology. Through the Production Promotion Corporation (CORFO), the State has injected more than 166 million dollars in technological development for the industry. In dramatic contrast, the scientific investment to understand the impact of lithium on water, microorganisms and threatened species – such as Andean flamingos – is barely close to 5 million dollars. Yovisibility territorial. Added to this institutional blindness is territorial invisibility. As the media explains South Slope when documenting the scientific project LiOness Ringthe public eye has become obsessed with evaporation pools, ignoring the off-sites: the areas outside the salt flats. Transportation routes, port terminals and transit communities silently absorb equal or worse impacts under “the excuse of green development,” researchers warn. For the National History Prize winner, Lautaro Núñez, cited by the same media, the key is being lost in the debate: “The salt flats are Chile’s heritage.” Thirst in the desert. As millions flow into technology, the ecosystem depletes. Extracting lithium requires pumping and evaporating enormous amounts of ancient water. As detailed The Confusioncurrent operations consume up to 12,500 liters of industrial water for every ton of lithium, causing the salt flat to sink up to two centimeters per year. Faced with this threat, the injection of money has caused the greatest historical fracture of the Lickanantay people. The communities went from blocking routes in January 2024 to fighting each other for the millionaire loot, which could reach up to 150 million dollars annually for the region, according to data from the Chilean government. Social fracture. Rudecindo Espíndola, local farmer cited by The Confusionassures that participating in this agreement is a form of “participation justice” because, after 12,000 years of inhabiting the territory, they will finally have physical access to the plants to supervise the mining companies. However, others see the destruction of their social fabric. Sergio Cubillos, president of the Peine community, recognize the same publication that “the fact that today communities receive money is what has led to this division.” Sonia Ramos, a respected 83-year-old healer, is even more blunt. in his interview with Climate Home News: “We are land and water (…) but today there is fragmentation. Everything has become unbalanced.” For her, the mining megapact does not bring progress, but “death, the total destruction of the Salar.” So what’s going to happen? Seeking to justify its expansion until 2060, NovaAndino has promised to stop using fresh water and reinject at least 30% of the brine into the subsoil through new extraction technologies. However, this promise is being viewed with great skepticism. As microbiologist Cristina Dorador warnsthese reinjection technologies are not proven on a large scale and could alter the chemical composition of the desert. Continuing pumping until 2060, he says, could be the “coup de grace” for this vital ecosystem. The State as a facilitator, not as a protector. Politically, the course seems unchanged. The recently inaugurated far-right president, José Antonio Kast, has already promised to respect the contracts signed by the previous administration. The machinery will continue to operate. In statements to MongabayHernán Cáceres, director of the National Institute of Lithium and Salt Flats (INLiSa), justified the low state budget in environmental areas by arguing that this money is actually an “enabling expense.” That is, the State finances ecological studies and dialogue tables not necessarily to stop the impact, but to “pave the way” for mining companies, reducing the risks of social conflict and guaranteeing that companies can operate without resistance from indigenous peoples. Blindfold. While technological investments advance at record speed, legal protection, such as the recent creation of the Network of Protected Salt Flats, moves at a slow pace, trapped in bureaucracy and lack of funds. The history of lithium in Chile encapsulates the great contradiction of our time. In the quest to clean the air in the metropolises of the northern hemisphere, one of the oldest and most biodiverse corners of the global south is being squeezed and fractured. As the research concludes, the country today faces a monumental challenge: … Read more

The big problem with nuclear energy has always been its waste. Russia can now recycle them up to five times

by

A nuclear reactor operating for 60 years using a closed system of three circulating fuel loads, subjected to cleaning processes and specific recharges in each cycle. What until recently seemed like an unattainable technical utopia for the energy industry is the reality that Russia’s latest technological breakthrough points to. The historic Achilles heel of nuclear fission—radioactive waste—is about to take a radical turn to become an almost inexhaustible resource. The magnitude of the test. The press release of Atom Media explains that Unit 1 of the Balakovo nuclear power plant (operated by Rosatom’s energy division) has just made history. They have successfully removed the last three lead test assemblies from an innovative fuel dubbed REMIX. These groups have completed three operating cycles of 18 months each. We are talking about 54 months performing at maximum capacity in a Russian commercial reactor type VVER-1000, thus exhausting its standard useful life. This puts the finishing touch to a demanding pilot program which started at the end of 2021 when the first six experimental rods were introduced into the reactor core. The resounding success. The most impressive thing about this milestone is not just that the fuel works, but where it works. Unlike other experiments designed for new generation fast reactors, REMIX fuel can be used in light water thermal reactors already operating massively around the planet. And without the need to modify its design or add costly security measures. The rehearsal went flawlessly. Yuri Ryzhkov, deputy chief engineer of the Balakovo power plant, detailed: “After each cycle, the fuel rods and structural elements were inspected using the television camera of the refueling machine. No deviations were detected during operation; neutron, physical and service characteristics remained within the design limits.” The science behind REMIX. But what exactly is this material? REMIX comes from Regenerated Mixture (Regenerated Mixture). Instead of using the usual natural enriched uranium, Russian scientists have created a matrix pellet that mixes regenerated uranium and plutonium (both recovered from already spent and reprocessed nuclear fuel), seasoned with some fresh enriched uranium. The technical key to the process is in the proportion: it maintains a very low level of plutonium, up to 1.5%. Thanks to this exact formulation, its neutron spectrum is practically identical to that of standard fuel. For practical purposes, the reactor core behaves the same and does not even “notice” the difference. The cleaning process. It is the circular economy taken to the atomic extreme. The magazine World Nuclear Newyes explains that this recycling cycle can be repeated up to five times. With each pass, the industry reprocesses the material to separate the useful uranium and plutonium from the fission products, which constitute the true radioactive waste. This useless waste is extracted and vitrified (encapsulated in glass) to be permanently and safely buried in geological deposits, while the useful fuel mixture is reintroduced into the reactor. The vision of the balanced cycle. Now it’s time for the laboratory and certification phase, where the irradiated material, now resting in cooling pools, will travel to the Atomic Reactor Research Institute in Dimitrovgrad for exhaustive analysis. Alexander Ugryumov, Vice President of R&D at TVEL (Rosatom’s fuel subsidiary), He announced that after these studies They will be able to bring the product to the market. The next evolutionary step will be to test mixtures with depleted uranium and up to 5% plutonium. All this is part of what Rosatom has called the “Balanced Nuclear Fuel Cycle” (NFC). The goal is to drastically reduce the volume and danger of radioactive waste, solving the historic problem of long-term storage for future generations and guaranteeing a truly sustainable production system. An impact on a global scale. Although the technical success is undeniable and the operational milestone in a commercial reactor is demonstrated, the mass adoption of this technology on a global level will largely depend on the commercialization costs and the economic viability of large-scale reprocessing; factors that the industry must demonstrate after the current qualification phase. However, if Rosatom manages to market REMIX at competitive prices, the global energy situation could take an unprecedented turn. We are not talking about a niche experiment. The data provided by Atom Media illustrate this magnitude: TVEL currently supplies fuel to more than 70 power reactors in 15 countries. Today, one in six reactors in the world operates with its technology. Moving from a linear “use and bury” industry to a closed loop where nuclear resources have multiple lives would not only dramatically expand the planet’s energy reserves, but could forever redefine the ecological viability of nuclear energy.

The first “autonomous” car in history dates back to 1958 and had a peculiar problem: it smelled like fish

Nowadays, and with few exceptions such as Cybertruckautomobile design is moved by very clear trends. However, in the 1950s and in the midst of the space age, the sky was the limit. Some examples are the amazing General Motors Firebird Ihe Zündapp Janus that you don’t know if it comes or goes or the refrigerator with wheels called BMW Isetta. At that time was born the Golden Sahara IIa car truly ahead of its time. It was so far ahead that it brought driving assistance and full connectivity (of what there was). It is, in short, the grandfather of today’s smart car. A crazy repair idea. If I say George Barris you may not know who I’m talking about, but if I reveal that he is the creator of the Batmobile things change. Well, back in 1953 the car designer had a car accident with his Lincoln Capri: crashed into a hay truck and as a result, the top of the vehicle was destroyed. Probably many of us would have taken the car to the workshop or scrapyard based on the mechanic’s bill, but Barris invested a whopping $5,000 and what was left of his battered Capri (which had a 200 horsepower V8 engine) was built into the Golden Sahara. Be careful, to give you an idea of ​​the inverted grassland: in the 50s the luxurious Cadillac Eldorado It cost $7,750.. Clean slate in the form of an ultra-futuristic car. Equipment from another era. At a time when FM radio was an extra, Barris himself tells its most differential design elements: hand-molded steel panels, vertical design headlights installed in fenders and bullet-type bumpers, fins integrated into the fenders, lounge-type seat with bar furniture on the sides, a removable bubble dome for the roof. Kontinent Media …and paint of with sardines The streamlined design was finished with a two-tone 24-karat gold finish (hence its name) instead of the classic chrome and a paint that shone like a diamond. Barris was looking for a finish never seen before, so he came up with a natural way to achieve a pearlescent touch before that type of paint became popular: with fish scales. As explained the designer in an interview with Jonnie King for his “Hall of Fame Legends” series: “So Shirley and I went to the fishmonger, and I remember that the fish looked very pearly. I had the fishmongers turn all the sardines so that their bellies could be seen until I found the one with the gold. We took it, removed the scales, put it in a jar, took it to the store and mixed it with a natural cellulose clearcoat and toner lacquers. Then I gave it a base of matte white and I sprayed it on top, and it turned out a spectacular pearly gold. The only problem was that it was very difficult to smell because it smelled like fish.” An even more extravagant Golden Sahara II. In 1954 the first Golden Sahara was born and from ’56 to ’58 Barris teamed up with Jim Street and Bob Metz to give it a twist until they found the Golden Sahara II. For this second generation, Goodyear added Translucent and luminous tires to replace the conventional white band tires of the time. It is just the tip of the iceberg of a car that is surprising both on the outside and (especially) on the inside. But Metz also gave it a good facelift and modified the windshield, hood and roof of the vehicle, he put quad headlights and rear fins. And it went from having a radio and steering wheel to truly futuristic technology: with panels on the upper part of the dashboard where it housed a television, tape recorder and even a refrigerator for its bar. It is said that the total cost of the Sahara exceeded $75,000 of the time. Under the hood: ahead of its time. Jim Rote’s electronics It was what made the difference compared to the cars of that era and brought it closer to ours. The steering wheel gave way to a fighter-style central joystick and implemented voice control for tasks such as opening the doors or starting the engine. Likewise, it integrated proximity sensors in two antennas on the front bumper, so that it could brake autonomously. What happened to him. In his days of wine and roses he went to fairs like the Petersen Motorama (his debut), he appeared in ‘cinderfella‘ (1960) with Jerry Lewis, Ed Winn and Judith Anderson and also in the competition ‘I’ve got a secret‘, in 1962. But in the 60s it disappeared from the front page and was relegated to ostracism for half a century, until it returned in style and restored in the Geneva Motor Show of 2019 from the hand of Goodyear.

Houston, we have a problem with Outlook. Microsoft spends millions on AI, but Artemis II does not escape the failures of its email

by

On April 2, we experienced a historic event for humanity: the mission Artemis II It successfully took off towards the moon after more than 50 years without orbiting near the Earth’s satellite. Although the takeoff was a success, the path to get here was not without problems: it already had to delay the first date launch and also the second. Even on the official day there were problems. In the previous hours it was necessary check an anomaly in a temperature sensor of a battery abort system and also appeared another incident in the flight termination system (the safety mechanism that makes it possible to destroy the rocket if it deviates from its trajectory and becomes a threat). When the Orion spacecraft was flying almost 150,000 kilometers from Earth according to FortuneCommander Reid Wiseman encountered a mundane problem faced by any mortal with a computer and Microsoft email: an Outlook crash. The incident. The launch of Artemis II could be followed live and in that live, approximately 13 hours and 15 minutes after the broadcast began there is a fragment where the problem appears: “I see that I have two Microsoft Outlook accounts, and neither one works. If you could connect remotely and check Optimus and those two Outlook accounts, that would be great.” At first, Wiseman had issues related to the Optimus software, but then he pointed out a more trivial concern: There were two instances of Outlook running on his personal computing device. As a curiosity, the live stream to follow the takeoff still available on YouTube. Why it is important. The Artemis II mission is historic and the stream has left for posterity its first hours of flight and this anecdote that constitutes what is probably the first Microsoft technical support ticket generated from space. Beyond the joke, the episode shows that today’s space exploration and its cutting-edge technology coexist with commercial productivity software and its common failures. When an agency standardizes its entire infrastructure on a single technological ecosystem, the problems of that ecosystem also become problems of the mission. Tap to go to the post There is a support ticket from the Moon. As with any standard corporate ticket, the user first reported the incident, the technical team took over remotely, and finally closed the case. Houston accepted the request for remote access to the commander’s device, identified in records as PCD 1, and about an hour later, Outlook was back up and running. After 14 hours and 20 minutes of broadcast, someone from mission control communication said: “We managed to open Outlook. It will appear as “offline”, as expected”, as pick up Tom’s Hardware. Why they use Outlook in space. That there is Microsoft software on board is not something casual or improvised: Microsoft is a strategic partner of NASA that provides everything from productivity software to cloud data infrastructure and artificial intelligence (NASA Earth Copilot), hardware and mixed reality and Minburn Technology Group is your partner for software support and maintenance. In fact and according to NASAthe personal devices of the astronauts on the Orion spacecraft are Microsoft Surface Pro and the software they run is Commercial Off-The-Shelf, That is, standard commercial software for everyday tasks like talking to your family or managing your photos and videos. Another thing is the spacecraft and main flight systems: these are powered by specialized radiation-resistant hardware and specialized software with rigorous maintenance. The bathroom was also broken. The Outlook failure was not the only technical problem in the first hours of the flight, as can be seen in the broadcast. About two hours after launch, a malfunction light came on in the ship’s waste management system: the urine extractor fan had jammed. This component is responsible for sucking urine into a collector, avoiding the uncomfortable and unhygienic effects of microgravity. NASA confirmed shortly after the toilet problem had been solved.
