Hi,

A video of my talk at H2O World in San Francisco recently :

    https://www.youtube.com/watch?v=MvH1eTdsekA

   0:00   Examples from two insurance companies using data.table
12:00   What is data.table, benchmarks dplyr and pandas
16:55   Overlap joins
20:00   Rolling joins
22:30   data.table radix sorting is better than hashing (dplyr and pandas)
23:00   H2O (just parallel file reading and grouping as quick test)
30:00   Quick rerun of talk at Bay Area R User Group (sorting benchmark, 
automatic indexes flows through to dplyr, numeric rounding)
33:10   My status
36:45   Questions
49:26   End

Comments/suggestions very welcome.

Matt
