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.

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

1. Follow standard conventions.
2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
3. Boy scout rule. Leave the campground cleaner than you found it.
4. Always find root cause. Always look for the root cause of a problem.

1. Get node binary (node.exe) from http://nodejs.org/download/
2. Create the folder where node will reside and move node.exe to it
3. Download the last zip version of npm from http://nodejs.org/dist/npm
4. Unpack the zip inside the node folder
5. Download the last tgz version of npm from http://nodejs.org/dist/npm
6. Open the tgz file and unpack only the file bin/npm (without extension) directly on the node folder.
7. Add the the node folder and the packages/bin folder to PATH
8. On a command prompt execute npm install -g npm to update npm to the latest version

Now you can use npm and node from windows cmd or from bash shell like Git Bash of msysgit.
