Timezones - There, Here, Then, Now, and Back Again.

by Joel Oliveira

Many of us have crossed the rubicon and tackled the tricky (and sinister) issue of handling timezones in our code. For those of you who haven't, or to varying degrees, this talk is for you. Why is this an issue? What tools are available to us? In my talk I'll share the challenges I've run into and share some code that makes it a little easier.

Raspberry Pi on Rails: A Burning Man Love Story

by Benjamin Guest

People don't typically think of Ruby when it comes to embedded Linux development boards like Raspberry Pi and BeagleBone, but it is indeed possible to run the full Rails stack on such systems and use that micro server to interact with the physical world. In this talk I'll show how Rails and Raspberry Pi are being used to create a simple interface for a Burning Man art project. I'll cover the pieces I used to get rails running on Pi, contributions to the pi_piper gem, software design decisions, hardware design and interaction, issues, and possibilities for improvement.
