As deep as I have to. Usually, I know in advance what I want to build with the new technology and what quality level my customer needs. I'm always super impatient to try new knowledge out in practice. So I'll learn for a day, then try it out in the evening. And then I only go back to learning as long as the results are still too bad to solve my problem.
