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:

Beyond Angular and Backbone with Unidirectional apps

What is a unidirectional app?

Unidirectional is a term coined by React engineers to describe the data flow of an application. Unidirectional apps employ functional reactive programming techniques such as immutability, purity, and most importantly unidirectional (as opposed to bidirectional) data flow.

A unidirectional app is defined by no mutable references no two-way references between concerns.
