DESCRIPTION
In this video we'll learn how Git utilizes pointers to make creating, deleting & updating branches easy and fast. We'll discuss Git's branching architecture, and uncover just what exactly the saying "branches are just pointers to commits" actually means.

thank you for a true lightbulb moment! It just makes sense now
Perfect explanation. Amazing channel
Much appreciated!
wow, your explaination was exceptional.
When you meet at the merge base of two branches, how does git know which of the branches continues and which one stops?
Essentially Git has this concept of first parent, second parent etc. Git keeps track of which commit is the primary parent and works backwards from there. Here is a good explanation of that in detail: stackoverflow.com/a/50437829
I'm an old-timer but recently new to git (~1 year).
Here are some ideas for content.. things I wish I knew and understood better, day one.
- how a PR is like a "live link" between two branches -- the way you can continue to push fixes to your branch, to address CR comments etc, while the PR is open
- what happens to a branch after it's been merged -- why does GH offer to delete it? that seems scary! (I get it, now -- it's just something unexpected and different than other source control systems)
- (more advanced topic) how to deal with merging to multiple upstream branches.. release-branches, hotfix-branches etc.
Thanks for these suggestions. Definitely want to do a video on PRs - I like your suggestion of including information about how PRs are updated during the review process, that's a great suggestion.
The unsung hero is Torvalds?
The man, the myth, the legend
He’s pretty well-sung tbf
Interesting video, but I think linked-list is a more accurate model of how commits are tied together.
I agree at a high-level, I just didn't want to get into the semantics of singly vs doubly linked lists, and assume the folks watching had pre-existing knowledge of that data structure.
the world could always use more git knowledge
I'm just interested in your mind. Why are you doing these videos?
In general? Or this video in particular?
@@themoderncoder In general
@OpenDeepLearning I started a dev blog in 2016 when I was working as a software engineer at a big FAANG company mostly as a creative outlet. Then I started to make little videos here and there (I knew a bit about video editing because I took a class in HS). Then it just grew from there.
I think the reason I’m doing this is because it feels good to help people. To make connections. I feel there are a ton of critical software development skills that are under-taught. Git is one of those skills, hopefully I can start covering more as the channel grows.
@@themoderncoder Thank you very much! You are an inspiration for me!
