pdxfunc is a study/user group exploring the world of functional programming, based in Portland, Oregon. The group welcomes programmers interested in all functional languages, including Haskell, Lisp, OCaml, and others. The group has been meeting regularly since November 2007 for presentations, demos and discussions applicable to all skill levels, from newbies and experts. Every month 15-35 people come together to share their knowledge, projects and enthusiasm for functional programming – join us!
There are many ways to participate in pdxfunc:
- Join our Meetup group, where you can RSVP for events
- Attend our meetings, they are usually on the second Monday of the month. If you have presentations, discussion topics or activities you would like to see, please post them to the mailing list or mention them at the beginning of meetings.
- Subscribe to our online mailing list to receive meeting announcements and notes, get suggestions of interesting events, and participate in technical discussions. You may post jobs and gigs for FP-related work within ~100 miles of Portland.
- Follow us on Twitter for meeting announcements and notes.
- Join us on Freenode IRC: #pdxfunc
- Join us on ePDX to tell the world that you're part of this user group and find others.

This month's meeting, 4/10/17
- Part 1: Haskell Lesson 3 by Echo, based on Brent Yorgey's CIS 194
- Part 2: Lyle will present an introduction to category theory
Notes from past meetings
Every pdxfunc meeting is full of awesome, but we often forget to take notes, so this is just a fraction of what we talk about in person. The most recent content is at the top:
- March 2017: Echo taught Haskell Lesson 2
- In February 2017, we started a new format where the first half is a lecture from Brent Yorgey's CIS 194, and the second half is an advanced talk. For February, Lyle gave the Haskell lesson and Leif spoke about data parallelism in Spark (Scala) and Haskell.
