Beets. Battlestar Galactica.

Thanks! Just a derivation of the famous phrase: http://en.wikipedia.org/wiki/Time_flies_like_an_arrow;_fruit_flies_like_a_banana

... fruit flies like a bottle of booze.

I just read the wikipedia article for Costas arrays, very interesting concept (I know little of discrete maths). I still don't like the way the guy at the talk presented the concept, but thanks for clearing it up :-D.

It would help if there were some definitions for "random" and "pattern-free" in this context. I find it annoying that he several times says that random music is not pattern-free.

It is true that their definitions are not equivalent, but it seems that he is implying that you cannot generate "pattern-free" music using randomly played notes, and that -depending of the definition of "pattern-free" of course- seems very, very unlikely.

Still, I can appreciate the effort to maximize information entropy, and the divulgation of discrete math.

This.

Could you elaborate on the differences beyond the different settings (SF vs Heavy Metal Fantasy)? (Honest question, I haven't played Brutal Legend)

That is false. It has a single player campaign. Maybe you're thinking of some other game?

Unless your grandma is John Lennon or something.

Heh, I wonder if "I can has cheezburguer" sounds to a native english speaker as funny as "yo puedo tiene hamburguesa" sounds to a native spanish speaker.

Alas, poor Nupraptor! I knew him well... well, not really.

And sometimes it's just homotopic to a 3-ball.

The Apollo Program used to reveal cities back in the day :P

Well, my reply was actually tongue-in-cheek because of the generality of my definition (used in algebra). I assumed the OP was talking about the integers, not the natural numbers. The integers are an integral domain, so the definition of primality becomes the one for integral domains.

So no, it's not redundant, given the conditions I assumed (I feel I have to say it explicitly this time :-P)
