Code Retreat @ Bento Miso

Welcome to Code Retreat Toronto! 

The event is for software developers from different paradigms to learn new techniques, languages, and practices from each other by pairing to solve a pre-determined problem. Participants must choose a new partner for each session and new programatic constraints will be introduced with each session.

The format is as follows:

6:00pm - 6:15pm: Introductions

6:15pm - 7:00pm: Session 1

7:00pm - 7:15pm: Session 1 Review

7:15pm - 8:00pm: Session 2

8:00pm - 8:15pm: Session 2 Review

8:15pm - 9:00pm: Session 3

9:00pm - 9:15pm: Session 3 Review

 

Make sure to bring a laptop and have your development environment ready for the type of coding you'd like to be doing.

    That was definitely atypical in terms of problem difficulty. Next month we'll be back to our regularly scheduled programming -- probably with a computing competition problem, or we'll trot out that old chestnut The Game of Life. Hope you all had fun. See you at the next one!

    That was a really tough problem, maybe suggest an easier question next time so we can spend more time learning a new language?

    A lot of fun. Too tired to think.

    I won't be able to attend today's meetup. Something popped up in the last minute. Sorry.

    We've done a lot of parsing problems recently, so this month we're going to change things up with a counting problem. Counting is fun!

    We'll start off by counting the number of ways a square of size N can be dissected into smaller squares. So, for example, a 2x2 square can only be decomposed into either 1 2x2 square or 4 1x1 squares, so square-count(2) == 2

    A 3x3 square is more interesting: it can be (1 3x3 square) or (9 1x1 squares) or (1 2x2 and 5 1x1s) -- but you can do that last dissection in four different ways, so square-count(3) == 6

    This sequence is http://oeis.org/A045846 (note the image links).

    If that proves too easy we'll then try counting the same thing, but ignoring dissections that are reflections or rotations of previously counted dissections. That sequence is http://oeis.org/A224239 and if anyone gets this far maybe we can extend it! More pics:
