And now I'm running out of time, but there's one more thing I want to talk about, which is my best friend git reflog.

git reflog is just a log of all the commit hashes you've ever been at, and why it changed. Using this you can recover from almost anything you do within git. Bad rebase? That's okay, branches are just pointers to commit hashes, and the old commits hashes are still there, same as they ever were. And the reflog remembers what those hashes were. Accidentally reset your branch to a bad place? Git reflog knows how to find your way home. Deleted a branch that still had a change on it you forgot to merge? The name may be gone, but the hash isn't. Reflog knows its old address, and you can just point a new name there, or inspect its log by hash, or cherry-pick it.

Git reflog loves you.

And now I have to go, but maybe I'll say more later.
