After buying a new laptop, I spent a lot of time with the Internet problem on Ubuntu. And I did manage to solve the problem. There were frequent connection breaks and the internet speed was very slow. At first, I was thinking about buying a new router, but at the same time under Windows 8 everything worked with a bang.
Once upon a time in the evening in one programmer chat, some programmers felt boring. And I don’t remember why, but we started to compare programming languages performance using the Fibonacci algorithm in its recursive implementation. Many times passed since it happened. Only artifacts such as source code left on my hard drive and that’s why I decided to create this post.
