FCC: SpaceX satellites in orbit - a source of debris dangerous to Earth’s inhabitants  
 
According to the analysis of the figures given by the FCC regarding the lifetime of SpaceX satellites (Starlink system) in Earth orbit, the probability of hitting someone on Earth with a satellite fragment will reach 45% every six years. It sounds a little difficult, literally it means that the fragments of satellites will fall to Earth every day, sometimes reach the surface of the planet, and sometimes kill someone from the people.

We correct typos in search queries

We correct typos in search queriesProbably, any service that generally has a search, sooner or later comes to the need to learn how to correct errors in user requests. Errare humanum est; users are constantly sealed and mistaken, and the quality of the search inevitably suffers from this - and with it the user experience. 3r3r6956.

Fault Injection: your system is unreliable if you have not tried to break it

Hi, Habr! My name is Pavel Lipsky. I am an engineer, I work in the company Sberbank-Technology. My specialization is testing the fault tolerance and performance of backends of large distributed systems. Simply put, I break other people's programs. In this post I will talk about fault injection - a testing method that allows you to find problems in the system by creating artificial failures. To begin with, I came to this method, then we will talk about the method itself and how we use it.

Production of the case for the robot with a limited budget. Vacuum forming

Production of the case for the robot with a limited budget. Vacuum formingHow to show investors a beautiful robot? Develop a beautiful body. How to do it while there is no investment? I tried to briefly describe my path. We develop Golf Ball Robot at the driving range . 3r3208. Without a beautiful body is very difficult to explain how the robot will look. [/b] In this article I will tell you how for 24000 rub. get a case of 1000mm x 800mm x 250mm, as well as what kind of rake we collected along the way. Perhaps this will help you avoid our mistakes.
