Pavel Varenka It's the last day of the week, and even though we've been reporting on all the curiosities and interesting news that happened during the last few days, this time we have a somewhat calmer conclusion. And not to mention, after the mysterious monolith and hateful ping pong between former US President Donald Trump and TikTok, a partial return to normality is more than welcome. So let's take a look at other news in the technological world, led this time by NASA with its open-source Raspberry Pi and Tesla, which is having problems because of the Model X and Y. We must not forget the mentioned evergreen, i.e. Donald Trump, who has finally partially acknowledged defeat and, with any luck, hand over the reigns to his Democratic opponent, Joe Biden.

NASA actively uses Raspberry Pi
If you are actively interested in technology, you have certainly not missed hardware in the form of Raspberry Pi, which has become synonymous with multi-functionality. You can program and use the device as you wish and you are not limited by practically anything, only performance. If you want to connect this small computer to a camera, for example, and recognize faces or capture space, nothing prevents you, in fact, quite the opposite. This makes the Raspberry Pi a great helper in many fields where no expensive equipment is needed and just something rich that will actively collect data and eventually send it to a much more powerful, remote computer. Even the famous NASA decided to use this method, which, thanks to the open-source concept, really went all out on the use of microcomputers.

Developers at NASA have been working for a long time on a special framework, F Prime, which will be used to observe and evaluate data. Although it could be argued that space toys are really expensive and need to be properly high performance, this is not always the case. Sometimes it is simply enough for the given device to receive or send signals, which is always useful in a spaceship. The creators have thus found several uses for the Raspberry Pi, whether it is an embedded device or flight control software. The field of operation of the microcomputer could also be in the very interiors and control centers of missiles, where the focus is on the highest possible responsiveness and the lowest response. This is definitely an interesting project that is worth watching.
Donald Trump has finally (almost) conceded defeat
The comedy called the American election does not end. Now the former US President Donald Trump has lost by a landslide against his democratic opponent, Joe Biden, and even though all media and radio stations confirmed the superiority of the Democrats, the head of the United States still refused to step down. After the votes were counted, Trump even called on his supporters not to believe the media and to recognize his sovereignty. This was understandably not met with a very favorable response and the controversial political figure had to leave with his head bowed. Despite this, the statesman continued to fight in court, arguing that the elections were rigged and that the Republicans simply had the upper hand. But after a long struggle, Donald Trump finally indicated that he might leave voluntarily.

Next month, the Electoral College, i.e. the representatives of the individual states, will officially decide and finalize their votes. In that case, there will be a formal inauguration of President Joe Biden and the Republicans will have to leave office. However, this does not mean that Donald Trump will stop judging himself. On the contrary, the courts are already investigating several complaints of election fraud and it will take months to come to a conclusion. Still, this is good news, as many experts expected the former US president to refuse to vacate his seat and try to block the Electoral College's decision. We will see how the representatives decide in the end next month. What is certain, however, is that the soap opera will probably continue for some time.

Vratislav Holub Tesla is having trouble making its cars
Although the gigantic Tesla boasts of precision engineering that cannot be compared with other car companies, there are still occasional problems that only add fuel to the fire of critics and bad tongues that do not wish the company success. In particular, there is skepticism regarding the new Y models, in the case of which there was a rather unpleasant manufacturing defect that caused the necessary recall of several thousand units. However, the X models from 2016 were not spared either, which serve extremely reliably, but not always with luck, which Tesla experienced firsthand. In total, 9136 units of both models had to be withdrawn from the market, i.e. both from 2016 and this year. The problem was quite simple - the cars were not properly constructed and there were regular technical problems.

However, it must be noted that these were relatively serious matters. Especially in the case of the Y model, for example, there was poor control of the steering wheel, which was not properly fixed, which affected the ability of the driver to react to unexpected situations. And this is not the first such scandal, recently Tesla was forced to recall a total of 123 thousand units due to the same problem. However, this ailment did not affect the company's shares too much and Tesla continues to grow at a steep pace, which is mainly reflected in record earnings, investor confidence and increased demand for electric cars. We will see if the manufacturer catches these flies next time, or if we are in for another similar negative experience. This is already how many politicians and experts express themselves negatively towards the car company.

Auto companies are recalling millions of cars in one go, but Tesla is in the same position as Apple. When something is wrong, it is better to write about it.
