Gasoline hoses have a tiny hole at the end. Without chips involved, it is the smartest piece in the entire supplier

If you’ve ever paid attention to the pump while filling up, you may have noticed that it has a small hole located near the tip of the metal nozzle. That little hole is, possibly, the most ingenious piece of the entire set. And it is responsible for the hose “knowing” when to stop adding fuel and stopping on its own with that characteristic click. What exactly is it. This small hole is located at the end of the pipe (the part that you insert into the tank) and is connected to a thin, secondary tube that runs inside the nozzle parallel to the main fuel line. The nozzle uses the fuel itself that is being pumped to create the effect that activates the automatic cut. So to speak, the little hole does not pour gasoline, but rather breathes air. How it works. The key is in a physical principle called the Venturi effect. While the fuel flows at high speed through a narrowing of the duct, a low pressure zone is generated that sucks air through that small hole in the tip. The Venturi effect occurs because The density of gasoline is greater than that of airand it is precisely this phenomenon that causes the dispenser to turn off automatically when the tank is full. The moment of cutting. When the gasoline level inside the tank rises to cover that hole, the tube stops being able to suck in air. When the airflow is cut off, the suction is triggered and creates a vacuum that pulls on a flexible membrane (a diaphragm) housed in the handle of the nozzle. That movement releases a lever mechanism that slams the main valve shut, stopping fuel instantly. The pressure change causes the diaphragm to “jump”releasing the mechanical lever that closes the valve and ending with a click. And as you may have already noticed, the cut occurs even if you continue to pull the trigger. 100% mechanical. This entire system is purely mechanical. There are no electronic sensors, no chips, no batteries. The handle simply generates a slight vacuum at the tip of the pipe, and if that point becomes clogged, a mechanism closes the valve. It is basic physics applied to this little invention that we use in our routine, and that is capable of detecting even a small amount of fuel, blocking the hole to prevent it from overflowing. Security and cuts. This system prevents gasoline from overflowing from the tank, something that would be dangerous (risk of fire) and polluting. But its usefulness goes beyond safe filling. This extraordinary sensitivity is also the cause of those premature and repeated cuts when the jet turns off even though the tank is not full. The most common cause of these annoying cuts is simply a little gasoline splashing back and covers the hole momentarily, activating the mechanism ahead of time. In cars with short filler tubes, a rapid flow can easily flood that column, so the first recommended remedy is usually to reduce the filling rate. The position of the nozzle and the temperature of the fuel also play a role. In Xataka | The United States has the best electric car chargers in the world. Europe has something more important

The Aragón justice system has shown how expensive it can be for a company to get involved with dismissal letters: 46,665 euros

There are mistakes that can be corrected with a simple apology. And then there are errors that, once committedhave legal consequences that no apology can undo. A freight transport company in Huesca discovered this in the worst possible way when it fired one of its employees, regretted it days later, trying to back down, and then fired him again. All of this while the worker was at home on medical leave. What seemed like an internal bureaucratic mess ended up in court and with compensation of more than 46,000 euros. The dismissal letters the devil carries them. Two layoffs, one leave and fifteen days of chaos. As documented in the sentence In the case that reached the Superior Court of Justice of Aragon, the worker had been in the company since 2011, with an indefinite contract, and had accumulated more than a year of medical leave due to a cervical injury when, on December 14, 2023, he received a burofax from his company informing him of the disciplinary dismissal. As indicated in the dismissal letter, the employee had carried out incompatible activities with his low status. The worker did not take long to react and began the process to challenge the dismissal in court. But then something unexpected happened. On December 20, just six days later, a second burofax arrived in which the company declared that the first dismissal was annulled and that an internal disciplinary file was opened in its place. Not satisfied with this, on December 29 they received a third burofax containing another dismissal letter, this time accompanied by the payroll and the corresponding settlement. Within two weeks, the employee had received two dismissal communications and one cancellation while was still convalescing at home. Why the company wanted to back down. As stated in the ruling, the company argued that the first dismissal had been a procedural error and considered that the initial letter had formal defects related to the applicable collective agreement, since the worker had questioned by email whether the merchandise transportation agreement or the chemical industry agreement should apply. The company’s intention was to annul that first dismissal, open the correct disciplinary file and issue a new letter in order. From his point of view, the only real dismissal was that of December 29, which had never been challenged by the worker. The company also tried to demonstrate to the court that the underlying reason for the dismissal was legitimate: a private detective report recorded the worker carrying out physical activity during his medical leave, which he interpreted as a simulation of the disability or, at least, as a behavior incompatible with recovery. A dismissal letter is not a draft. The problem for the company is that the dismissal letter is not a simple administrative communication with the employee, but is a document with key legal value with which an entire dismissal process begins with very well-defined deadlines and procedures to give maximum guarantees to both companies and employees. He article 55.1 of the Workers’ Statute establishes that disciplinary dismissal must be notified in writing, with the facts that motivate it and the effective date. Once that letter is delivered, a legal mechanism is put in place that neither party can stop unilaterally. The law itself contemplates the possibility for the company to retract the dismissal and provides a way out when a company wants to correct a poorly formulated dismissal, but as stated in article 55.2 of the Workers’ Statute, it is subject to very precise conditions and deadlines. Furthermore, it is only admitted if, during that rectification period, the company keeps the worker registered with Social Security and pays them all salaries. In this case, the ruling states that it was not proven that the company had complied with that requirement, which blocked this means of rectification. Without the worker’s acceptance, there is no turning back. On the other hand, and beyond the administrative procedures, there is an additional requirement that the company did not comply with in its process of rectification of the first dismissal: for the employment relationship to be restored, the worker who has been dismissed must expressly accept it. It is not enough for the company to declare on its own that the dismissal is without effect. The Supreme Court already established that a communicated dismissal determines that the worker is not obliged to accept any subsequent retraction from the company, and that claiming before the courts in that situation does not constitute any type of abuse. In this case, the employee did not explicitly accept the annulment of the first dismissal or return to his position. The email he sent to the company questioning the applicable collective agreement was not considered by the court as a tacit acceptance of the withdrawal, but rather as confirmation of his dismissal status. The employment relationship, in the eyes of the law, had been terminated on December 14 and no subsequent communication from the company could change that unilaterally. The outcome: more than 46,000 euros in compensation. The TSJ of Aragón also ruled out the argument about physical activity during sick leave. It was proven that the outputs recorded by detective They were walks or runs of about 40 minutes of moderate duration that, according to the medical assessment, were not contraindicated for the worker’s recovery from the cervical injury. With all these arguments on the table, the court declared the dismissal inadmissible, the first, because the second no longer had any legal value, and established compensation of 46,665.34 euros, calculated based on age of the worker. The company appealed that decision to the Superior Court of Justice of Aragon, which confirmed it in its entirety and also ordered it to pay 800 euros in costs. Dismissal letters, especially if they are not well formulated, are carried by the devil.

The Singapore government has revealed which companies are involved in the delivery of GPU from Nvidia A Deepseek

Depseek continues to be the artificial intelligence (AI) of the moment five weeks after its irruption. And is that the debate about the hardware used by this Chinese company to train your AI model Keep on the table. High-flyer, your parent company, is A quantitative coverage fund specialized in trading algorithmic. This simply means that this company uses advanced mathematical models and computational algorithms to address investment decisions with the greatest possible success guarantees. Deepseek was born as a high-flyer secondary project to take advantage of its computer resources and “put one foot” in the AI ​​industry. Its creators say that in the training of their model they have used only 2,048 chips H800 of Nvidia. However, Some analysts defend that, in reality, its infrastructure brings together 50,000 GPU H100 bought through intermediaries. This is the problem. High-flyer could legally buy the H800 chips to the entry into force of US sanctions of November 16, 2023, but the H100 GPUs should not be in their possession. Singapore is the entrance door to China of the chips for the most advanced Nvidia The US government has suspected for many months that Chinese companies and research centers dedicated to AI acquire the most advanced NVIDIA GPUs through Singapore and Malaysian intermediary companies. This possibility is no longer just a hypothesis. And it is that the Singapore government has confirmed that it has identified those responsible for diverting to China, and presumably towards the Deepseek parent company, servers that contain the high -performance GPUs produced by NVIDIA. The US now has the opportunity to tighten its fence a little more about China This information was revealed last week by the television channel Channel News Asia, and today the Minister of Internal Affairs and Justice of Singapore, K. Shanmugam, He has confirmed it. Interestingly, it has not specified what the GPUs that incorporate these machines, but it has made public a very important fact: The name of the companies They have manufactured the servers. And they are two very important Nvidia customers: Dell Technologies and Super Micro Computer. If it is finally confirmed that Depseek, or any other Chinese company that is dedicated to AI, is getting the Nvidia avant -garde GPUs acquiring servers of these companies in Singapore or Malaysia, USA will have the opportunity to tighten your fence a little more. However, this would not demonstrate the guilt of Dell and Super Micro, although its indirect involvement in the traffic of the Nvidia chips. This circumstance would put on the table the need to control with more precision where their servers will stop, something that, on the other hand, It is not easy. Whatever the Singapore government claims to be willing to collaborate with his American counterpart to end the illegal vanguard GPU traffic.
