• Embedded Application on the Erlang VM
    In this presentation Chris Coté of the National Association of Realtors will dive into Nodeponics - an automation system for aquaponic systems. It runs on small embedded computers such as a RaspberryPi (https://www.raspberrypi.org/). At it's core Nodeponics is a UDP server and client that communicates with a Particle.io Photon (https://www.particle.io/products/hardware/photon-wifi-dev-kit) based control system,SensorNode (https://github.com/entone/SensorNode) Nodeponics monitors and controls several water quality measurements, such as temperature, Dissolved Oxygen and PH. Along with logging data to local DETS tables, it also saves timelapse images to Amazon S3 for later viewing. It provides a simple web frontend for monitoring which provides Websocket and MJPEG interfaces for data display and control. Nodeponics is built using Elixir (http://elixir-lang.org/) and Nerves (http://nerves-project.org/) - however it makes extensive use of core Erlang platform features including OTP.

  • Erlang Patterns Part Deux
    In our summer edition of Chicago Erlang we'll revisit the important topics of patterns in Erlang. This is a followup to our November 2015 meetup, which was on a blustery cold Chicago night and we got distracted by type systems and bijon frises. We'll spend time moving erlangpatterns.org forward by capturing new patterns that we like (and anti-patterns that we dislike) as well as refining existing content. This is a great topic for advanced Erlangers and those who are learning - it bypasses technical arcane knowledge and emphasizes human emotion as the indicator of great wisdom!

  • Build Your Own Web Framework in Erlang
    Erlang is literally _the_ best language for front end web development! And while it's technical merits loom large over prevailing web languages Ruby, Python, and PHP, Erlang is not commonly viewed as a web programming language. In this installment of Chicago Erlang we'll build a custom web framework in Erlang from scratch! You'll learn the basics of HTTP and how incrementally build a full fledged web application in Erlang without the help of a giant framework like Rails or Django.

  • Erlang Patterns - November 2015
    We will spend the evening diving into Erlang Patterns: http://www.erlangpatterns.org We'll briefly walk through the concept of patterns, according to Christopher Alexander who invented them, and how they can apply to Erlang programming. We'll then break up into working groups to create and refine content from the site. If you're new to Erlang this is unique opportunity to learn about the language using patterns, which are non-technical on one hand, and very technical on the other. If you've got some Erlang experience, this is a great chance to contribute to a growing body of patterns that can be used by all far and wide. In any case, you'll have a blast and learn a ton! Be there!

  • Erlang Elixir Family Reunion
    Did you know we have blood relatives living in Chicago? It's true! Elixir is a language that compiles to code for the Erlang VM, shares many of Erlang's libraries, adds lots of new features and has the best build tools on the block! And while Erlang is superior in every way, it doesn't stop us from welcoming this clan into our family with open arms! On Sept 17 we're holding a family reunion, with a talk to bring both groups together under a common banner. Irina Guberman - a long time Chicago Erlang member - will share her experience using Elixir and it's popular web framework Phoenix. Irina will explain the motivation for her betrayal, I mean experimentation, with this other language and help us understand what we could possibly learn if only we maintain an open mind! We'll have all the fixin's of a family reunion, including lasagna in a pan, cup cakes in a box, punch (spiked and unspiked), and break out fights between estranged first cousins! Don't miss this night of festivities, fun, and family as we set aside our differences, listen with open hearts, and try to all get along for a few hours!
