Wow, this is freaky. I've never read up on git's diff-stat.
There are numerous advanced mathematical methodologies that
can be applied to histograms, some of which run blazingly
fast on GPU and customer gate arrays. I wonder where I can 
read up on "diffstat" and see what mathematics they are applied
or are contemplating to use? Google reveals nothing yet
and I'm too lazy (right now) to read the code.

diffstat reads the output of diff and displays a histogram of the
insertions, deletions, and modifications per-file. It is useful for
reviewing large, complex patch files. "


this is really cool, I shoot one from the hip and it is a well
established tool? scary, but, math is math..... 

Do you know (of) this guy? is he easy to approach or territorial?
I never heard of this guy.....

Beyond elegant. Some very cool mathematics can be applied to (histogram)
verious images and image manipultation as a sort of "out of band" security
scan..... There are also some very cool bit manipulations deep in
H.264 that are similarly applicable.  In fact "motion detection" 
is a first cousin to these transfroms (z, laplace, fft) which are often
embedded in hardware for system checks). DOD......

Well, I'm off to go play basketball and the the Tampabay Devil rays
(hopefully) pound those cleveland indians.........

I'm jazzed. I usually lucky when hips shots do not richochet around and 
hit me in the rear!.............

Since I'm not driving, I going to have a BIG FAT MARGARITA, and give you
a salute at the BB game.... You've made my week!  




thx!
