Wow, this is freaky. I've never read up on git's diff-stat. |
13 |
There are numerous advanced mathematical methodologies that |
14 |
can be applied to histograms, some of which run blazingly |
15 |
fast on GPU and customer gate arrays. I wonder where I can |
16 |
read up on "diffstat" and see what mathematics they are applied |
17 |
or are contemplating to use? Google reveals nothing yet |
18 |
and I'm too lazy (right now) to read the code. |

diffstat reads the output of diff and displays a histogram of the |
22 |
insertions, deletions, and modifications per-file. It is useful for |
23 |
reviewing large, complex patch files. " |

Beyond elegant. Some very cool mathematics can be applied to (histogram) |
41 |
verious images and image manipultation as a sort of "out of band" security |
42 |
scan..... There are also some very cool bit manipulations deep in |
43 |
H.264 that are similarly applicable. In fact "motion detection" |
44 |
is a first cousin to these transfroms (z, laplace, fft) which are often |
45 |
embedded in hardware for system checks). DOD...... |

Well, I'm off to go play basketball and the the Tampabay Devil rays |

Since I'm not driving, I going to have a BIG FAT MARGARITA, and give you |
