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

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

Comments/suggestions very welcome.
Matt
