Git is the distributed version control system that's taking the world by storm. The Linux kernel, Ruby on Rails, and now even Erlang/OTP have all chosen it as their VCS of choice. This talk will focus on mastering the handful of commands that comprise 90% of the functionality you will use on a day-to-day basis. I'll kick things off with the best method to install Git on your favorite platform. Next up is creating local repositories, staging/adding files (all about the index), making commits, and viewing history. From there you'll learn to share your repositories with others via GitHub, fetch and merge changes that others make, and resolve conflicts. I'll also introduce a few common workflows that you can use to streamline collaborative development. Each step of the way I'll demonstrate the commands and explain what's happening under the hood to help you establish a proper mental model that will enable you to master the more complex parts of Git with ease.

Dropbox stores only 1 copy of every unique file and serves everybody the same unique file - provided that it is the exact file - but charges everybody for the full file size. E.g. if 1 person uploads a 5MB file, but 99 other people upload it too, they don't have 100 copies of that 5MB file for 500MB of storage. The only use 5MB of storage, but charge everybody's quota of 500MB.
