Last Monday I gave an Ignite talk at Strata NYC about using command-line tools for data science. Giving a talk where the slides auto-advance after 15 seconds is a challenging, but ultimately very rewarding experience! Even though the preview image below suggests otherwise, there's no beatboxing in this video.
On a related note, I'm writing a book titled "Data Science at the Command-line", which will be published by O'Reilly somewhere in 2014. If you're interested in receiving updates regarding the book then you should follow me on Twitter.
