  • A few weird ways of displaying git hashes

    Personally, I prefer the Emoji one over the colored bars, as I seem to be able to tell them apart without actively thinking about it, while the color one needs my attention.

  • Commiting without Git

    Matheus answers the question how little one has to do to get a simple valid repository with content.

Late addition:

  • Inside .git

    The contents of the .git folder explained in detail by the masterful Julia Evans.
