More data apps spawned by Sandy
As the clean-up continues on the eastern seaboard, I wanted to follow up on Monday's post on tracking Hurricane Sandy with Open Data with a couple of other R-based data applications spawned by the storm. Josef Fruehwald created an R script to tap into local weather sensors to keep track of air pressure, wind speed and rainfall near his...
Quick notes from Strata NYC 2012
The O'Reilly Strata conferences are always great fun to attend, and this latest installment in New York City is no exception. This one is super-busy though; the conference has been sold out for weeks -- and not just marketing-sold-out, it's fire-department-sold out. It's non-stop conversations and presentations, and it's tough to move through the hallways in between. Nonetheless, I...

Designing real-world 3-D objects with R
The Maker Movement has led to the production of open-source 3-D printers and other manufacturing machines that allow hobbyists to design, create and produce real-world objects affordably. Now R user Ian Walker, in a post at the Psychological Statistics blog, shows how to use the R language to transform 3-D surfaces into real-world physical objects with a 3-D printer....
Using R in production: industry experts share their experiences

A video map of the hottest songs in the US
Today's guest post comes from Revolution Analytics data scientist Luba Gloukhov — ed.

The social crowdfunding site Kickstarter announced today that it has enabled, via community contributions, $50M in funding in 2012 for new indie games. The second largest category of funding was for independent films. The blog post announcing the news includes analysis (using R, natch) of the breakdown in categories and funding sources.

R does CSI: Using R to nail break-in suspects
You've probably heard (or seen in TV shows) how the unique pattern of rifling in a gunbarrel generates forensic evidence: microscopic scoring on the bullets left at the scene of the crime can be linked to the shooter by matching the marks to the firearm. What you might not know is that the same technique can be applied to...
