@Jerocis: The difference (well, one of them, anyway) is that the Internet-connected computing device today is in your home, your pocket, your car, your television, your glasses, your shoes, your ears, your eyes, your...
@HeavensRevenge: Thanks for watching! (and I was just jabbing you about the ladies comment). I like the Brian-Dan combo best for TWC9. Good humor, smart perspectives and they invented the show (Greg Duncan does the heavy lifting around content, of course). I'll always fill in when needed, as a favor to my friends. I'm looking forward to Brian's return.
@NodeAtTheEdge: Life is a fine answer. Good thinking! That said, like energy, life is not immune to entropy... Still, the answers are suitable, at a high level (and the question was lofty to begin with). C
Sure, in its simplest form, recursion can be function (input) -> side effect (output) -> function input (side effect (output)) -> you're passing side effects into f and computing f with that data until some state is reached (unless you're infinitely computing...). So, in this case, a result is passed to itself (function), not itself, which is the basis of the question (by definition, a side effect of x that is x is x).
A function, f, that returns f would be a sufficient answer to this question. Or would it? More interestingly, as Erik Meijer answered ( he did the homework, too ), energy, e, could be a correct answer. How so?
Question 42. C
PS: On an unrelated note (or is it? Is knowledge a side effect of itself?), did you read the history of 0/1 based indexing? What do you think of the author's take?
