We wanted something to do on our train journey from Vancouver, Canada to Portland for Railsconf 2013.
So we built something that will save us some data charges when looking up the schedule on our mobile devices.
This has been written in PDD (Pry driven development) TDD (train driven development), so no tests here.
We have a master branch on this project that creates the cached JSON data structure of the talks and speakers, you can access the latest processed data here:
http://caliper.github.io/railsconf2013/raw/data.json
The javascript application sits on the branch pages.
Feel free to fix or change something, send a pull request and we'll merge it in.
