Question

IT education

Hi friends.
Surprisingly, but the fact is that having a diploma of a programmer, I know practically nothing.
While studying, we studied html, css, delphi, on which three programs were written, after that I worked at the school enikey worker + 44fz, there she finally degraded, because there was no soil or funds for professional growth.
At the moment, on maternity leave, I plan to enter the enterprise after.
Salt of the question: what can I study while I'm sitting at home?
I am close to: applied programming, testing, information security, but there is so much information everywhere, I don’t know what to take.
I look forward to your advice.

Answer 3

You first ask yourself the question: what do you want to get in the end? I didn't see the purpose in your question. What is the purpose ? Go to the enterprise? What enterprise? Show everyone what's cool? Earn a lot of money? Travel to conferences?
And then we can talk about ways to achieve this goal.
By the way, the absence of a goal is the main obstacle in the implementation of the plan.
