About this blog
This blog is mostly about my pursuits in Data Science. Previous blog entries also dealt with storage, compute, virtualization and professional services. Currently the focus is on Data Science, including Big Data, Hadoop, Business Intelligence, Data Warehouse, Data Integration and Visualization. From time to time I will blog about other things of interest. The opinions expressed in this blog are entirely my own and should not be taken as the opinion of my employer.
