A Partial Remedy to the Reproducibility Problem
Several years ago, John Ionnidis jolted the scientific establishment with an article titled, "Why Most Published Research Findings Are False." He had concerns about inattention to statistical power, multiple inference issues and so on. Most people had already been aware of all this, of course, but that conversation opened the floodgates, and many more issues…

The Data Science Venn Diagram
On Monday I—humbly—joined a group of NYC's most sophisticated thinkers on
all things data for a half-day unconference to help O'Reily organize their
upcoming Strata conference. The break out sessions were fantastic, and the
number of people in each allowed for outstanding, expert driven,
discussions. One of the best sessions I attended focused on issues related
to teaching data science, which inevitably led to a discussion on the
skills needed to be a fully competent data scientist.

As I have said before, I think the term "data science" is a bit of a
misnomer, but I was very hopeful after this discussion; mostly because of
the utter lack of agreement on what a curriculum on this subject would look
like. The difficulty in defining these skills is that the split between
substance and methodology is ambiguous, and as such it is unclear how to
distinguish among hackers, statisticians, subject matter experts, their
overlaps and where data science fits.

What is clear, however, is that one needs to lea

Data Science at the Command Line
We data scientists love to create exciting data visualizations and insightful statistical models. However, before we get to that point, usually much effort goes into obtaining, scrubbing, and exploring the required data. The command line, although invented decades ago, is an amazing environment for performing such data science tasks. By combining small, yet powerful, command-line tools you can quickly explore your data and hack together prototypes. New tools such as parallel, jq, and csvkit allow you to use the command line for today's data challenges. Even if you're already comfortable processing data with, say, R or Python, being able to also leverage the power of the command line can make you a more productive and efficient data scientist.

“Ninety-three percent of the speech is completely different,” declared Gov. Chris Christie of New Jersey. Paul Manafort, Mr. Trump’s campaign chairman, pegged the number of suspicious words at 50. “And that includes ‘ands’ and ‘thes’ and things like that,” he said on Tuesday.
