The World of Data, as We Know It

Every year, human beings and our machines generate more data than we ever have before.  We’ve all heard the famous estimation from Eric Schmidt when he was CEO at Google in 2010: “There was 5 Exabytes of information created between the dawn of civilization through 2003,” he proclaimed, “but that much information is now created every 2 days, and the pace is increasing.”

Chess Analytics in R

For quite some time I have been interested in determining whether material or mobility is more influential in determining the outcome of a game in chess, and I recently did a statistical analysis on a large database of expert-level games to try and answer that question.

The results are rather surprising, and I have written a brief technical summary of the methodology as well as the results. The R code used to perform the…

The mock border closing for the Civilian Data Army was just the beginning in 2019. The goal to catalog every American in America had been laughed at so much by media it has become cliche. The rebellion has all the makings of a massive movement. The media could not control it. Everyone wants answers. Real complete answers. The people are ready. Fueled by anger and fed up with the secrecy and disrespect of personal data they demand change.



The early years of data science in the 21st…

Most certifications are not worth the paper they are printed on

Certifications exist to keep HR happy and provide another stream of revenue for the companies giving the certification. They test you on a lot of material you will never use. Also, by the time you get the certification, they are out of date. Of course, you can also say the same thing about most technical education, particularly now. It is better to prove you actually can do the job (somehow) rather than pass the certification. I am an example. About 15 years ago, I was out of work, so I…

Why the NoSQL Movement Should Have Been Called the JSON Movement

By Andy Palmer, Co-founder and CEO of Tamr

We all know by now that most “big data” challenges can be characterized into one of the “3 V’s”:

Volume:  You have too much data

Over the past 5 years, my partner Mike Stonebraker and I have been on a mission to raise awareness of the…
