Array Programming with NumPy
Don't underestimate the impact this has on getting funding or even just tenure/etc recognition for working on numpy.  I'm in industry these days, but coming from the academic side, it's _really_ hard to get recognized for building the underlying infrastructure that tons of people use.  I've built and maintained libraries that are used in a ton of publications, but was always told my work was "utterly and completely useless".  It was also always unpublishable, as methods are never publishable in my field. Numpy has (obviously) vastly more respect and impact than my work, but the general problem remains.Articles like this are a _huge_ deal for that reason.  It's an immense delayed recognition for over a decade of work from a lot of folks.
