Nice paper from 2013, but I was confused at first how it related to the blog. This paragraph just after the abstract explained, but I missed it the first time through:
The original article in PDF[1] was published at the NCSU COE
People site. It was translated and published at our blog
by the authors' permission. At the end of the article[2], we
added a short section about the PVS-Studio analyzer, where
we describe which of the recommendations suggested in the
article are or aren't implemented in our tool and why.
