You're entirely right, I was mistaken about the author. It sounds similar to a Stephen Wolfram post though; these guys really, really love Mathematica (understandably), and every post goes to great lengths to explain how they've done something incredibly novel which was only possible because Mathematica is fast and versatile, etc. The end result was really impressive, and I know they got there using Mathematica (in some cases), but I was more interested in the techniques and the approach they took than the particular language they used. All of the puffery and going out of the way to talk about how terse the code was seems excessive.

Definitely written by Mr. Gray.

That being said, Stephen Wolfram is surely at least a little pompous...
