Git Under the Hood: Demystifying the Beast
Most developers use Git every day, yet it often feels like a mysterious black box. Why does it behave that way when rebasing? What really is a branch? Why does Git seem to remember things you thought were gone?
In this talk, we’ll go beyond git add, commit, and push, and dive into the core concepts behind Git. You'll learn:
How Git stores your code under the hood (blobs, trees, and commits)
What branches really are (just pointers!)
Why rebasing isn't scary — once you understand it
How to develop a mental model that makes Git make sense
With visual explanations, real demos, and some cool lesser-known tips, this talk will help you use Git more confidently — and even recover when things go wrong.
Take a peek under the hood of Git and uncover how it really works. This talk explores Git’s internal structure, branches as pointers, and the truth behind rebase — with clear visuals, live demos, and practical tips to boost your confidence and control when using Git.
