The Thrill of the [Data Science] Chase

Data Scientists are a unique group. We come from a variety of backgrounds with a unique set of life experiences. At Booz Allen our data science team is now 500+ strong. We have the people you would expect – those with degrees in math, stats, and physics. We also have a forester (me), a jazz musician, and a computer graphics major. There’s no set approach or ‘one size fits all’ model. We all took a different path to get to where we are today, but we all share one common trait – we never get…

Drake, AC/DC, and...Steely Dan?! Twitter Reacts to Coachella 2015

Music fans with long memories probably recall the lamentable fiasco that was Woodstock 1999. In contrast to its '60s antecedent, Woodstock '99 was a cravenly commercial venture that replaced Jimi Hendrix and Janis Joplin with Kid Rock and Godsmack. Temperatures hovered in triple digits. Food and water were in short supply. Candles distributed for an anti-gun vigil were used to start plastic bottle bonfires. Limp Bizkit was prominently featured. 

It was the worst of…

Data Science Art

This picture below represents a piece of paper where I wrote down my ideas for new articles, in the last few days, when making my 10 am tea pause. The tea kettle leaked on the sheet, slowly creating the brown stain. Many of my previous ideas were written with a purple pen, creating the purple stains.
