How to get familiar with new technologies?

Question

Programming

Hello.
I worked as a web developer for about half a year, and also occasionally study at home in my spare time.
Today, I have been familiar with the python language for a year now, and about a year ago I started to get into web development.
At the time of my acquaintance with python, I already had some skills with C ++ at the base level, to display the integral sine on the screen, and in view of this, my learning was already much faster, and then I started writing in javascript without reading a single book about it, which to do further had to naturally.
Over the past year, I got acquainted with django, backbone.js, and other related technologies.
My question is actually brewing here.
What is the recipe for learning new languages/technologies?
Is it worth it for me to study Ruby further or Tornado or Angular to read a whole book about this, which will talk a lot about the philosophy of this tool, how it works? Or is it worth looking for some superficial methods?
If anyone thinks that the second method works well, could you please provide resources to learn some web technologies in a very fast way?
Thank you for your attention.

First, look well for a couple of those that you already know.
There is nothing faster than documentation.
RTFM

Learn the architecture of building programs Hello World! in various languages.
Next - compare the differences and learn what is new for you.

Set tasks, select tools for them, solve them.
The second point of the plan is the most difficult. No one often can really explain what this tool is for. Even the developers themselves. Come at random.
It's not the same for everybody. To me, Google is the fastest. I can google anything, if it exists at all. A small working source is more informative and convenient for me than a manual on how to write it.
And for some, video tutorials, manuals and books are better. It depends on the mindset.
