Hacker: An enthusiastic and skillful computer programmer or user.
Cracker: A thin, crisp wafer often eaten with cheese or other savory toppings.
...
Intruder: A person who intrudes, esp. into a building with criminal intent.
I refuse to be labeled as either or. I will now only acknowledge the term "intruder" to refer to a person who modifies, or breaks into, an information technology system with or without consent of the system's owner.

Besides, that Eric S. Raymond creep is the one who started that "hacker vs. cracker," nonsense. Just look at a picture of the man! How could you ever take someone seriously, when they look like that?

Not saying I'm on expert on any subject matter, but that's my opinion, and I'm entitled to it...I hope. Also, I wouldn't exactly refer to anything taken from the Jargon Wiki/File as authoritative, because that's exactly what it is...Jargon. It has no intellectual value to anyone except for the people who use it.
