Git Compression of Blobs and Packfiles.

Many users of Git are curious about the lack of delta compression at the object (blob) level when commits are first written. This efficiency is saved until the pack file is written. Loose objects are written in compressed, but non-delta format at the time of each commit.

A simple run though of a commit sequence with only the smallest change to the image (in uncompressed TIFF format to amplify the observable behavior) aids the understanding of this deferred and different approach efficiency.

The command sequence:

Create the repo:

#!/bin/bash

# play YUV444 FULL HD file 
gst-launch-1.0 -v filesrc location=size_1920x1080.yuv ! \
    videoparse width=1920 height=1080 framerate=25/1 format=GST_VIDEO_FORMAT_Y444 ! \
    videoconvert ! \
    autovideosink

# play YUV422 FULL HD file 
gst-launch-1.0 -v filesrc location=size_1920x1080.yuv ! \

First of all, it just seems like doing anything with Oracle is obnoxiously painful for no good reason. It's the nature of the beast I suppose. cx_oracle is a python module that allows you to connect to an Oracle Database and issue queries, inserts, updates..usual jazz.
