Books VS Webinars?

Question

IT education

When studying the material in the book, there is no more in-depth understanding of the process of working on the code.
In the book, information is also sometimes far behind in time, because typesetting, correction, printing, etc. it takes more than one month, and even a year.
And in the video, the lecturer, as a rule, forgets about many subtleties, because he does not read his practices from the sheet.
Is there a third way of self-education, which is devoid of the disadvantages associated with the above teaching methods?
