Commentaries and logging

[betelgeusealaska]

Hi, @TesterReality!

I'm really curious about your project. I'm solving same issues in my project related to voice messaging. But I've encountered a lot of issues while watching your code.

In this issue I've decided to focus on logging and commentaries. First of all, commentaries in the code on foreign language. I think it should be Russian. I've tried to translate it but still I can't understand them. Can you explain code in ThreadPoolServer class, have a lot of issues with it.

Also I can't figure out what's going on in logging. As I understood, you use sout everywhere in the code. This is also a trouble.
