On “Ask HN: Is there a “ground-up” explanation of PGP/GnuPG?”
Scott Chacon's videos are priceless. (He's the co-author of the git book.) They explain exactly how git works internally in the simplest terms possible. Either or both of these: Introduction to Git - talk by Scott Chacon link Introduction to Git with Scott Chacon of GitHub link to this video The latter is newer but a bit longer. Don't be fooled by the video names, these are introductions to the internals not just the interface.
