Hello Portland!

Let's talk Erlang, Elixir, OTP, scalability, uptime, web apps, beer and all things computer industry.

Got something to share? Looking to learn? Drop in and join us!

Come hack for transportation! Help make apps using TriMet data even more awesome and accessible to more community members in Portland.

The TriMet Hackathon will have three areas of focus: software localization, TriMet's new APIs, and Active Transportation using OpenTripPlanner, OpenStreetMap, in conjunction with Metro's Bike There program.

Please join the TriMet Developers, Code 4 Portland, Skip Newberry, Chris Smith, Brandon Martin Anderson, Ed Groth, Chuck & Erica Lauer Vose, Marc Charbonneau... and many others.

If you've heard of Erlang, perhaps you've also seen the acronym "OTP". What the heck is "OTP" and why do the Jedi refer to it as the "magic" that gives Erlang it's reputation for scalability and fault tolerance?

Why is it called Erlang/OTP? What gives? How does this relate to Elixir? What should I know about it?

Nathan Aschbacher of Visa and Elixir Games PDX has kindly agreed to join us and share his wisdom, give us an overview and also, to levitate R2D2.

Our generous hosts this month are HouseHappy.

October we followup on this deep topic with Jeff Weiss showing self-healing application magic in Elixir and OTP. Hope to see you there!

Jeff Wiess will share his presentation from ElixirConf EU and give us a live demo:

Chat Bot: A Practical Walkthrough of the powerful Features Elixir/Erlang/OTP

Bring your laptop and be ready to help us try and crash Jeff's chat server service.

Written in Elixir, a "Ruby-like" flavor of Erlang this demo will show supervision trees, clustering and live code updating.

Erlang On NixOS - Managing And Releasing Erlang Systems In The Cloud With A Fully Declarative Package Manager

In this talk we will discuss how to manage Erlang dependencies with the Nix package manager and how to use the Nix system to deliver declaratively described images containing an Erlang Release to cloud platforms.

Talk objectives:

To educate the audiance about the value of using a functional, declarative package management system to deliver functional, declarative systems.

Target audience:

About Eric Merritt

Co-author of Erlang and OTP in Action, open source contributor, Erlang Engineer.

Jesse Cook will lead our exploration tonight.

Jesse: A beginner Alchemist who's really enjoying the functional nature of Elixir and the design of the language.

Description: Moving complexity around - What's the best way to provide a unified API in front of some of the worst APIs out there? The tools I reached for are Phoenix, Absinthe for GraphQL and a series of adapters. These adapters utilize both polymorphism and metaprogramming, but was this the right way to do it in Elixir? Let's discuss the overall architecture and the nitty gritty details.
