Ask HN: Who is a hacker anyways in today's context?

It has almost been 1 year since I starting reading HN and must say I absolutely love it. From time to time, I have read diverse articles on the topic of "hacker".

I am really itching to ask the question here so that the experts can take a shot at it. Is learning a bunch of new technologies enough to make someone a hacker? Does randomly pulling in a git code base and modifying it make one a hacker? And the biggest doubt I have: Does a CS degree automatically qualify someone as a hacker?

Not sure if anyone shares my opinion: I just don't get the same heroic feeling I use to get when I used to hear the word "hacker" a decade ago. Any thoughts on this? Who is a hacker anyways in today's context?
