comment What is the importance of mixing caused by outgassing in the ocean?
@IsopycnalOscillation: I think it's pretty clear: The ocean is mixed by a number of processes (meridional overturning, thermohaline overturning, diffusion, eddies, giant squid...). One of those sources of mixing is up-welling gasses released by the ocean floor. How important is that source relative to all of the others combined (once you take absorption into account)?

comment Is it true that earthquakes are not felt in a cave?
@JoeKington: Wouldn't your animation only be relevant for the surface waves? I would think that something like this example of underwater explosions exerting pressure on balloons would be more relevant for pressure waves travelling through the crust.

Ah! So the entropy/MI value is a per-sample average value, and the dataset I created actually needs 92000 nits to store. That makes a lot more sense, thanks!

Hrm.. yes, I guess I already understand that. It doesn't seem reasonable that you can use <1 bit to store the distribution of a coin toss though. I mean, one bit is basically true or false, right? Or is bit used in a different sense in this context?

comment how can i tell select() in dplyr that the string it is seeing is a column name in a data frame
Not sure, sorry. ?get mentions mget, but it doesn't seem to work for me..

comment How can 2 strings be concatenated in R
Heh, this is the only answer that addresses the fact that tmp is a vector, and not just a bunch of values - paste doesn't do vectors. The other option is do.call(paste, as.list(tmp)).

"skewness" kind of thing - last sentence in the question.

Need: not really. I was just thinking about being able to smoothly morph between synth sounds (and being able to produce nice sounds in between the common patterns), and wondered if this might be a way to do it. The last suggestion sounds sensible, although I'd guess the sin wave doesn't lie directly in between the triangle and square, but I guess you could just split it into two sweeps.. That might make the second parameter impossible to figure out though. Interesting.

You could also use np.polyfit(x, y, 1).

Yeah, ideally the parameter sweep would evolve smoothly from one function to the next (e.g. continuous in the parameter dimension as well as the x dimension).
