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:

tmux cheat sheet

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a

WARNING : This code now lives in its own github repository: lovasoa/fast_array_intersect. It is also published on npm: fast_array_intersect

Array intersect

Fastest function to intersect a large number of big arrays in javascript, without dependencies

The compressed version is only 345 caracters long.
Faster than common libraries, even a large number of arrays, or on very big arrays. (See benchmarks)
