How to recover a dropped stash in Git?

How to recover a dropped stash in Git?

1. Find the stash commits

git log --graph --oneline --decorate ( git fsck --no-reflog | awk '/dangling commit/ {print $3}' )

This will show you all the commits at the tips of your commit graph which are no longer referenced from any branch or tag – every lost commit, including every stash commit you’ve ever created, will be somewhere in that graph.

Samba 4.1 on FreeBSD 10.1

Samba 4.1 Active Directory Domain Controller on FreeBSD 10.1

To simplify home network management, I recently decommissioned my beefy domain controller/file server/Hyper-V host, moving mass file storage to the cloud. I thought I could live without Active Directory, but with 5 PCs and a couple of Windows tablets, I want it back, so my plan is to host a tiny VM instance in hyper-V on 4 of my desktop PCs, creating something like peer-to-peer AD (hopefully with little overhead).

The following references were incredibly helpful, but neither were perfect for getting up and running quickly, hence this gist.
