Neat overview of some of the core concepts in Git that often go unnoticed. Although I'll say that the fact that commits are technically not diffs doesn't seem to matter much in day to day use. Git does a decent job of abstracting that detail away to the point that you could just as well believe commits are diffs. Also, I want to say that technically I believe Git does use deltas to compress an object's history in the blob store. But the different blobs that comprise an object's history can be thought of somewhat as being separate. Git could just as easily not perform this internal, space-saving optimization and things would all work the same. The SHA hashes would be the same and based on the same input.
