FamDav posted:graph theory is p cool and a lot of it is fairly intuitive. i think rotor or someone posted this book and its heck of cheaper: http://www.amazon.com/gp/product/0486247759/ been meaning to pick it up myself but havent gotten around to it. was it someone here who linked a linear algebra book that taught it "the right way" by teahching determinants last? trying to remember the name or where i heard about it. linear algebra was interesting but i took it in a summer semester and the pace was brutal and i didnt retain as much of it as id like.

Hhey scrubs here's a challenge problem. Harry and Sally are going to play a game where they split up a Hershey Bar. The Hershey Bar has 5x5 sections, with little indentations as the grid lines. Every turn, they break some part of the bar along a grid line. They have to go horizontal or vertical the entire way across, so they can't turn corners or whatever. Whoever breaks off a piece in such a way that there are no more breaks to make is the winner. But. If Harry is the starting player, then Sally has a guaranteed winning strategy. What is it?

when you break it in two what becomes the broken-off part and what remains? (it's a metaphor)

When a part is broken off it still counts as part of the bar. So if you break it into a 3x5 and a 2x5, you still have the gridlines of both pieces to worry about still. That's important sorry

oh fine then to break a chocolate bar of dimensions NxN into N^2 individual pieces you require (N+1)(N-1) breaks. since 5 is odd it will require an even number of breaks. oh actual if N is the total number of chocolate squares it takes N-1 breaks. so yeah, winning strategy is to play FamDav fucked around with this message at 04:14 on Feb 12, 2013 |

good attempt everyone. The answer is that since there's 25 pieces and each break makes a new piece, both players can just break it however and then Sally wins.

what if the chocolate bar has almonds and sally is allergic does swelling up and dying count as a win, i dont know much about game theory

the more interesting question is: you have a MxN chocolate bar, and players take turns eating one square and every square below and to the right of it. whoever finishes it has to throw away the wrapper and loses. analyzing the game itself isn't that hard but analyzing multiple copies of it at once (where you have multiple bars, and the loser is the person who eats the very last piece of chocolate) is interesting

i was already doing a bit of ember (last year, before they changed basically everything, so got to relearn it) and part of the reason i want to do rails is because a lot of the ember build tools are intended to integrate w rails or rack or rake or whatever you can use it separately of course but i figure it's so used in general that i should have at least a working knowledge. not going to be what i focus on for the next three months but will try to do at least one good project

abraham linksys posted:rails is loving weird yall A good supplement to that is Rails for Zombies. Be warned though, rfz is p useless as a standalone learning tool (welcome to school.0!), so definitely read that book a ways first. Oh and it has an obnoxious zombie theme. But afaik there is no book like that for Django.
