What language / technology to start learning on the New Year's "vacation"?

Question

Java

I am an android developer, I would like to learn something interesting this holidays. Initially, I looked at Scala or Erlang, but now I have doubts. Something related to the backend is interesting. What would you advise?

Answer 1

You can try Scala or Go.

Answer 2

Learn clojure xD

Answer 3

In the question, you wrote an Erlang tag. Erlang, of course. :) Everything is easy, the main thing is to develop the necessary reflexes.

Answer 4

Ruby - Ruby on rails web Framework, Scala - Play web Framework, PHP - Laravel web Framework

Answer 5

If Java, then JDBC, Java EE, you can look at ORMs, including for android, the same Hibernate (although it seems to be little used in android, as far as I know). You can look at google web toolkit - it's a cool thing.

From the frameworks I saw the vacancies of Spring, Spring MVC, Struts.
What salaries for such vacancies do you think you know.

Answer 6

I'll try to drag you to the dark side - look at Go, especially since since version 1.4 it has been friends with android
