R has become a massively popular language for data mining and predictive model building with over two million users worldwide. The wide adoption of R has to do with the fact that it is available as open source, runs on most technology platforms and is commonly taught in academic institutions in courses with significant components of data science, machine learning and statistics. A recent study found that R is now cited in academic papers more often then SAS and SPSS, a change from previous…Continue

The figure titled "Data Pipeline" is from an article by Jeffrey T. Leek & Roger D. Peng titled, "Statistics: P values are just the tip of the iceberg. These are both well known scientists in the field of statistics and data science, and for them, there is no need to debate the importance of data integrity; it is a fundamental concept. Current terminology uses the term "tidy data", a phrase coined by Hadley Wickham from an article by the same name. Whatever you…Continue

Buzz words are one of my least favorite things, but as buzz words go, I can appreciate the term “Data Lake.” It is one of the few buzz words that communicates a meaning very close to its intended definition. As you might imagine, with the advent of large scale data processing, there would be a need to name the location where lots of data resides, ergo, data lake. I personally prefer to call it a series of redundant commodity servers with Direct-Attached Storage, or hyperscale computing with…Continue

An entry in any one of these indexes is a reason for calling it what ever you want capitalism, freedom, justice, etc… Now if you are listed in all three indexes the privilege is unique. It is the privilege of being sold to the highest corporate bidder.…Continue

Most of us would probably like to work in a profession recognised for its legality, decency and honesty. At least I hope so. In my line of work, what we have right now is palpable evidence that the IT industry lacks a reliable moral compass.

Primed to make a huge entrance in 2015, Data-as-a-Service (DaaS) empowers companies with real-time data to overcome tough challenges with data. DaaS is allowing companies to generate real-time insights and revenue from Big Data. Companies commonly report feeling overwhelmed solely by the mere size of big data, not to mention the processes necessary to use the data. This no longer has to be a reality. With DaaS using big data is no longer a couple month long process.
