Portland Functional Programming Study Group - Haskell Lesson 7 and A* in Elm

Collective Agency Downtown
511 SW 10th Ave, Suite 1108
Portland, OR 97205, US (map)

Access Notes

We're on the 11th floor, come on up. Non-members park bikes outside the building. Paid car parking is connected to the building, and a SmartPark is two blocks away near Target. Located on SW 10th and Washington, between Target and Powell's, on the big block of food carts. We're on the Streetcar line, a block from the Red and Blue MAX lines, and a 5-minute walk from the Green, Yellow, Orange lines.



This month, we'll be meeting in a new location! Collective Agency has moved to 511 SW 10th Ave. We'll be meeting in the main area.

First, we'll cover Lesson 7 on Folds and Monoids from Brent Yorgey's CIS 194 Haskell lectures.

Then, Jamon Holmgren will explain his implementation of the A pathfinding algorithm in Elm. A is used in games to calculate the least-cost path for a computer character to move from one spot to another. Elm is a language similar to Haskell (but simpler) that compiles down to JavaScript, used for apps that run in web browsers.
