what is the best sources for learning programming?

Quite simply: doing programming.

Nothing is better than practice, and that's especially true of complicated stuff like programming.

Personally, as far as what language, I'd suggest Python (check their official tutorial in the documentation to get started), Go (same as for python, they have an interactive tour you can go through online as part of the docs), or possibly C (this one I can't suggest a good starting point for unfortunately) if you can wrap your head around the concept of passing around references to where things are instead of passing around the things themselves.

Since you mentioned no books or videos. Try freecodecamp.com. Sooner or later, you will find videos and books/documentations important for learning materials

Eloquent JavaScript is a great resource if you choose to learn JavaScript. It is a book, but is available free online. Is you preference for "no books" due to the cost, or just preferred learning style?

I'm not clear why you would not wish to include books and videos. Doesn't leave a lot.
