For your data analysis pleasure, I give you a giant list of super cool publicly available data. If you’re looking at the data sets and wondering “now what?” – you can find this list AND tutorials on how to use H2O for analysis at the H2O docs page (here: http://docs.0xdata.com) .
You can also get a detailed hands on experience analyzing any of this data, random numbers you might have laying around, stuff you made up, or whatever you want by coming to any of our upcoming meetups and hanging out with the 0xdata math team (http://www.meetup.com/H2Omeetup/).
