The Harvard Business Review (@HarvardBiz) online magazine^* is chock full of great articles, many of which intersect with the notion of creating compelling narratives and/or visualizations with data (two of the premises we talk about frequently in our book). Here are some excellent data-oriented articles there that I felt ...

Well over a year ago, I stumbled across “Mapping Bike Accidents in R” and was immediately taken in by the possibilities of creating videos from data. Since then I’ve done several videos, mostly just for fun. We also touched on the topic rather briefly in our book, and I ...

There was an interesting question recently on StackOverlow on how to apply a function over a rolling window on a column in a data frame grouped by subset. It was a pretty vanilla SO question as those things go, but there were no less than four useful and diferent answers ...

Jay should really know better than to leave all his desktop windows up when sharing a screen over Skype with me.

In Part 1 we looked at acquiring raw data, and wrangling it into a time series dataset. Now we will examine AlienVault types in the reputation database. Listing 3-22 of Data-Driven Security shows R code that groups type categories into a larger group of “multiples” when there is a semicolon ...

Jay & I will be doing a podcast on RSA + METRICON 9 soon, but over the weekend I managed to make a "Storify-ed" recap of it from tweets that went throughout the day. While I already posted a direct link to Storify on Twitter, here's a re-post of it on DDS.
