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:

How you can help reduce node_modules bloat

This recent reddit thread reveals discontent among the web development community about the sheer volume of stuff in a typical node_modules dir. 140MB in this case!

Is it a design flaw in npm?

Opinions in the thread varied from "I'm surprised npm even works" to "everything is fine". I'm not going to offer an opinion, just these two observations:
