The following sentence is annoying, but also true: the best time to learn Git was yesterday. Fortunately, the second best time is today! Git is an essential tool for work in any code-related field, from data science to game development to machine learning. This course covers everything you need to know to start using Git and Github in the real-world today!
Next up, we change gears to focus on Github & Collaboration. We start by exploring Github (and similar tools) that host remote repositories and discussing the benefits they provide. We create our own Github repositories and sync up changes between our remote and local repositories using the git push, git pull, and git fetch commands. We then focus on commonly used collaboration workflows that students may encounter in the real world: feature branching, pull requests, forking & cloning, and more! We discuss contributing to open source projects and configuring Github repositories for collaboration. We also spend some time learning about useful Github features including Github Gists and Github Pages for free static hosting.
The last unit in the course, The Tricky Bits, is really just a collection of useful Git command and advanced topics. We start by covering one of the “scarier” Git commands: rebasing! We discuss the potential benefits and pitfalls of rebasing and compare it to merging. Then we learn how to clean up our Git history by rewording, editing, dropping, and squashing commits using the interactive rebase command. Next, we discuss Git tags (lightweight and annotated tags) semantic versioning and tagging workflows. After that, we move on to a deep dive into the inner workings of Git. We discuss the files and folders Git uses internally, the role of hashing functions in Git, and the role of Git objects (blobs, trees, etc.). Next, we talk about reference logs and the git reflog command. Specifically, we learn how we can use reflogs to rescue “lost” commits and undo rebases. Finally, we learn how to write custom and powerful Git aliases!
Throughout the course, you’ll find tons and tons of diagrams and visual references I’ve created to try and explain Git. The course also includes exercises I’ve tested on my in-person students, to give you an opportunity to practice the concepts in the course along the way. If you are reading this sentence, I congratulate you on making it this far 🙂 I hope you enjoy the course!
