Ask HN: If you could master one technology this year, what would it be?

WebGL. I can see it being used for a lot of interesting graphics applications in the browser.

SciPy: <a href="http://www.scipy.org/" rel="nofollow">http://www.scipy.org/</a> If you know that and the background math it requires, then you are fit to work in almost any data analysis setting you can imagine.

Native mobile app development - Java [Android] and Django / or any other framework.

I would choose native mobile app development (with a focus in iOS).
