Categories for the Working Programmer

Monads get most of the press, but the field of mathematics known as category theory contains a number of other useful concepts applicable to functional programming. At this meetup, James Dabbs will give a whirlwind tour of functors, monads, and more, and how they benefit you, the working Clojure programmer.

Pizza and socializing starting at 6:30pm. Talk starting at 7:00pm.

    Great talk on monads and categories a couple weeks ago. Fwiw, this paper is a nice, clean intro to monads as well: . I found that Figure 4 on p. 3 really helped me visualize what is going on.

    I came across this conversation: about the use of monads in Clojure. Maybe we can talk at the meeting about why life is about to get hard in Clojure if you "write sequence that takes a list of (f a) to f of (list a)" ? I have to confess I don't quite follow.

      I'd be glad to contrast working with monads in Clojure and Haskell, but I'm not entirely sure I follow that comment either: if you look at the haskell implementation of `sequence` (http://hackage.haskel...­), it looks like it'd port cleanly with `reduce` and `domonad` ... I'll ponder that a little more, time before the talk permitting.
