Hardware Hacking and M2M Websites with Ruby

by Steve Morss

We will go over some interesting devices for hacking using Ruby (Arduinos, XBees, others). They have open source code available and good documentation. Next, we will demonstrate a website written in Sinatra which gives complete control over the devices, and which can configure them into some interesting systems. Systems include a motion detector which sends text messages or email, a system which controls LEDs and relays using text messages or email, and a system which measures temperature and water/moisture and sends warning messages and status. We'll also demonstrate some low cost, hockey puck sized Linux systems (Raspberry Pi, others) functioning as a larger M2M system.

Three Client-side Web Apps

by Brian Kaney

Brian will dive into three recently released, client-heavy JS web applications. All use Ruby on the server; two of them use Backbone.js and the third uses Ember.js in the browser. Each project has is fair challenges, from scaling to security to development process and devops. We will look at a few of these challenges and how they were overcome.
