Git From the Bits Up

a good presentation and the best explanation of `git rebase`i've seen so far

Any video which focuses on the beginner aspect of git?

Thanks.

Weird question, but does anyone have any idea what font he is using in the console?

I think it's monospace Monaco. ( which is the default monospace font for mac )

anyone know why what he first tried with hash-object didnt work?

The .git directory was missing the HEAD file (which also must contain a ref; at least "ref: refs/"). I don't think this requirement was just introduced in 1.8.2 though.

Thanks a lot! Keep up the good work :)

If git requires people to 'look inside the box' sometimes to get it to work, it means it sucks. It is typical that an uber geek create git. Great coders are crap designers (but they THINK they are good designers...). Have you ever seen a website created by a coder!? Eek!

Am I the only one that thinks he sounds like Louis CK?

55 minutes worth spending (or 27 at 2x speed) :) Awesome presentation! 

Heh, "the detached HEAD state, not as bad for git as it is for you" :)

Final command needed to make .git directory from scratch work on newer versions of git:

echo "ref: refs/heads/master" > .git/HEAD

great lecture ... btw .... what git terminal is Tim using to use the tree command, as git bash v1.9.4.msysgit0 doesn't seem to be accepting this command???

great talk!

Great talk. Learned a lot about git internals from this talk. I wish your initial attempt of creating .git sub folders to trick 'git status' worked. Did you figure out what additional items you had to add to make 'git status' happy?

Pardon my ignorance, but was it python he was using to write the while loop?

you can do better at vim at 51min.

Very entertaing talk.

Fantastic talk, learnt alot, now I can feel more confident in rebasing. Thanks for sharing :D

Great talk. Shame about the way he swallows water so noisily.

This is actually really helpful. Thanks for the video.

Awesome talk. but what exactly are the deltas?

That is the issue with Git - questionable system design. I mean - If one needs to teach details of "under the hood" mechanics of a tool for people to get it, then it is not an intuitively useful tool. But yes - Git is the most beautiful of ALL UGLY version control thingies we have.

This was not helpful for me.

Also, the simplest way to revert a merge would be to use:

git reset --merge ORIG_HEAD

Oh man, does this ever help me. Seriously, this is the way to learn Git. Following tutorials and entering commands means you have to stick to a very specific workflow because if anything goes wrong with the black box you're just out of luck. You engage panic mode, git is broken and you might as well delete all your work, clone the repo again and start over because you don't have the vocabulary to even explain what's wrong. It might take a bit more time and effort to learn Git from a lower level, but I think this is absolutely necessary for working with Git in any way.

Masterful. This was a tour de force.

This is THE best video on git, thank you so much Tim great tutor.

Poorly thought out presentation. Not useful for developers who want to learn git. If he really is a trainer, he's a bad one.

Minimal required .git content has 2 empty directories {objects, refs} and a file {HEAD}, with HEAD having "ref: refs/heads/master" string as its content.
After creating above, git status won't throw an error.

🙏 🙏 🙏 thanks!!

And I read git tits up

Excellent talk, learned so much about git internals. Literally the best video on git internals.
