Development vector in network programming?

Question

MySQL

Hey!
Such a question, I chose for myself the direction of network programming, so to speak, I'm not sure that the term is suitable.
Data transfer.
List of questions:
1. List of literature that you need to study (without the basics of a particular language, please advise something in-depth and in the direction, python, c\c++)
2. What areas of knowledge should be monitored?
3. What test project to start doing to understand the basics of writing protocols?
4. Which of the "new" PLs are suitable for solving the task? (Go, NodeJS, Rust)

Answer 1

In /etc/mysql/my.cnf (or nearby) you need to comment out the line: Then restart MySql.

Answer 2

Um, how did you "choose" network programming, if you, judging by the questions, know absolutely nothing about it?
