Coding CodeMash

CodeMash has made their schedule available as an API. I decided to write an Android App to consume it. I have the app calling the API retrieving the JSON and then inserting into a local db. I now have to pull the data out and process it. I want to be able to select a day and then a time frame and return all the sessions for that time frame. At this point I am not sure the database is persisting.

I did spend some time today learning about Matrices. I read about them in an old game programming book and at WebGL Fundamentals
