Your second comment in 1 year and 8 months and it's about a common mistake/typo LAME. posted by tellurian at 6:15 AM on March 11, 2010 [2 favorites]
Well that's a half hour gone. Excellent. posted by pupdog at 6:25 AM on March 11, 2010
Awesome, thanks.
DreamerFi, your link makes my head hurt. posted by shothotbot at 6:40 AM on March 11, 2010
No, no, no. I have to leave for work, like, seven minutes ago. posted by phunniemee at 7:13 AM on March 11, 2010
This is great! Thanks. posted by joedan at 8:06 AM on March 11, 2010
My kids are going to love this as much as I did. Fantastic. posted by davejay at 10:26 AM on March 11, 2010
Also: I'm not going to get any work done today, am I? I wish this was a thing you could hold in your hand and use, like an etch-a-sketch. For the first time, an iPad makes sense. posted by davejay at 10:30 AM on March 11, 2010
I knew my comment was wrong at the time, but now I can quantify how wrong. In the general case of n objects that you are choosing k of and you can have as many gaps as you want, the count is (I think...my officemate is convinced anyway): (2n)!/(n!k!(2n-k)!).
But in the special case where n = 2k, as it is here, it is just 2n-1. (Proof: Pascal's Triangle. QED.)
So there are 213 songs we can make with this, which is 8192. posted by DU at 11:23 AM on March 11, 2010
Thank the gods you posted this on Thursday and not Monday. Thank the productivity gods indeed. posted by leo. at 2:15 PM on March 11, 2010
For DreamerFi's link: ignore the instructions, and just play with the tone matrix. It's awesome. posted by HeroZero at 4:30 PM on March 11, 2010
DU, the sum of the first eight terms (k = 0 thru 7) of the n = 14th row of Pascals triangle is 9,908.
So there are 9,907 combos if you don't count silence. posted by abc123xyzinfinity at 5:58 PM on March 11, 2010
Last time we played with a tone matrix I spent a little time with it (read: way too much time with it) and made an audio-visual performance for my fellow MeFites. posted by Ian A.T. at 6:05 PM on March 11, 2010 [2 favorites]
Oh, it looks like I had an off-by-one error on the rows. (We somehow managed not to write down the second row...) But the general solution is still right. I hope. posted by DU at 4:10 AM on March 12, 2010
yah, awesome - gracias! posted by jammy at 5:25 AM on March 12, 2010
