Locating an article is not a software development problem, regardless of what the article is about. Questions that are nothing more than a request to an external resource are off topic, not only on Programmers but on Stack Exchange in general, this isn't a link sharing service.
From the FAQ:
Programmers — Stack Exchange is a site for professional programmers who are interested in getting expert answers on conceptual questions about software development.
Finding an article or a blog post is not a conceptual software development question. We make a small exception for canonical books, but that's the only exception, not the rule.
