This is part 1 of a series of articles where I explore music data sets using various similarity metrics and heuristics.

From Max Weinreich, a phantasmal puzzle:
Twenty ghostbusters are on their annual camping retreat. Two of them, Abe and Betty, have discovered that another pair, Candace and Dan, are in fact ghosts posing as ghostbusters. Abe and Betty hatch a plan: When all 20 campers are sitting in a circle around the campfire, Abe will fire his proton pack at Candace, and Betty will simultaneously fire her proton pack at Dan, annihilating the ghosts. However, if two proton streams cross, it means the end of all life on Earth.
Five Thirty Eight Riddler Express Problem - Sep 1, 2017¶
You’re hanging out with some friends, shooting the breeze and talking sports. One of them brags to the group that he once made 17 free throws in a row after years of not having touched a basketball. You think the claim sounds unlikely, but plausible. Another friend scoffs, thinking it completely impossible. Let’s give your bragging friend the benefit of the doubt and say he’s a 70-percent free-throw shooter.
You take half of a vitamin every morning. The vitamins are sold in a bottle of 100 (whole) tablets, so at first you have to cut the tablets in half. Every day you randomly pull one thing from the bottle — if it’s a whole tablet, you cut it in half and put the leftover half back in the bottle. If it’s a half-tablet, you take the vitamin. You just bought a fresh bottle. How many days, on average, will it be before you pull a half-tablet out of the bottle?
Nothing excites me more than a good mathematical puzzle. Even if I don't end up solving one, I always come out richer in the process by improving the way I think. Combinatorial problems in particular are my favourite.
So you can imagine my excitement when I came across this really interesting probability / game theory riddle recently, courtesy Peter Norvig's Ipython notebooks
I want to compare my last.fm scrobbles with that of my friend's and arrive at a metric that quantifies the similarity between us in terms of musical preferences. I'm looking at just one variable here, the number of times a particular artist is played and will approach this problem …
I have a confession of sorts to make. As a little kid, when I wasn't chasing dragonflies or playing carroms or scribbling my name everywhere, I used to be engrossed in this rather weird game.
I would start by doing something trivial using one of my hands, say …
SymPy is a package for symbolic calculations in python, similar to Mathematica. It works with expressions containing symbols.
అవిస్మరణీయ పాత్రగళ్ indeed!
Watched Thithi today. Loved it. Raw and gritty portrayal of the human condition. You should do yourself and the team that made it possible a favour by spending your hard earned moolah on this.
The story and climax in particular reminded me …
Nope. This has absolutely nothing to do with Abstract Algebra. What we have here is a short film where one alien explains to another about musicians, producers, mixers and their social standings, capitalism, free market etc against a backdrop of performances, album covers, band photos and the song Free Will …
