I’ve found currency exchange rate data for almost every second of each day (sometimes several times per second) for the past 12 years.
Time to write a few analysis tools and then parallelize the shit out of them. Map/Reduce seems like a reasonable approach.
His work becomes much more intense industrial wise in the album Doll, Doll, Doll. But I suggest that, The Avalanches, Refused, and Aphex Twin.
Thanks much! =D
This. is. amazing.
Seriously, this is exactly the sort of non-distracting thing that puts me into a mathematical mojo. I’d enjoy this a little a lot more for casual listening too, I think.
Thanks! Feel free to share any more, I’d love it! =D\

I don’t usually listen to dubstep unless I’m programming, but I’ve put this on a few times to dance around like an idiot lately.

We had a contest in a class of mine once to see who could hide the most data in an image of a cow the teacher gave us.
who won, and how??
My group won =D. Our approach was fairly naive; we only had 30 minutes to create and implement our idea.
Essentially, we decided that you could modify each component color of a pixel by at most some value (I think 3 was what we guessed because we didn’t have much time to test?) without modifying the image greatly. We then broke down the input into a series of trinary numbers, and determined how to modify each color value of each pixel sequentially such that (value % 3) corresponded to the appropriate value in the file and such that that color value was minimally changed (for example, should we add or subtract so that modulus operation gives the correct result?).
It turns out that 3 is actually a poor estimate, I recall, and for some reason I remember somebody in my group later saying 8 was better for optimal data stored vs. noise. This technique ought to work better than simply replacing least-significant bits.
Our teacher told us about when he gave the assignment to some grad students with a bit more time. The group that won out of them did analysis of tiles of images, and would encode more data into tiles where there was a greater amount of natural noise. Apparently it worked pretty well.
Microsoft are not in my good books, and they will be getting only the blackest coal for Christmas this year and, in fact, every year until they improve.
Why are you using Visual Studio anyway? It’s a terrible IDE with a terrible toolchain. Switch to the GNU toolchain, it’ll increase your productivity tenfold.
Maybe not for C#… But if you’re using C++ then certainly.
I’m lucky though, I got a free version of Visual Studio Professional from my school =D.
