Preparing a hashed password with Jupyter Notebook

http://jupyter-notebook.readthedocs.io/en/latest/public_server.html#preparing-a-hashed-password

You can prepare a hashed password manually, using the function notebook.auth.security.passwd():

In [1]: from notebook.auth import passwd
In [2]: passwd()
Enter password:
Verify password:
Out[2]: 'sha1:67c9e60bb8b6:9ffede0825894254b2e042ea597d771089e11aed' 

You can then add the hashed password to your jupyter_notebook_config.py. The default location for this file jupyter_notebook_config.py is in your Jupyter folder in your home directory, ~/.jupyter, e.g.:

c.NotebookApp.password = u'sha1:67c9e60bb8b6:9ffede0825894254b2e042ea597d771089e11aed'

Resolving conflicts on a git branch

You'll need to update your branch with new commits from master, resolve those conflicts and push the updated/resolved branch to GitHub.

Resolve conflicts

I found these instructions much better than the instructions from Bitbucket involving a detached head! Thanks jaw6!

git checkout master
git pull
git checkout <branch>
git merge master
[ ... resolve any conflicts ... ]
git add [files that were conflicted]
git commit
git push

Merge master

git checkout somebranch # gets you on branch somebranch
git fetch origin        # gets you up to date with origin
git merge origin/master

If it all goes wrong somehow, reset with the following (but ensure you're previously checked in as you can lose work with this command!!)

git reset –hard
git reset --hard <SOME-COMMIT>

Bonus: reverting local changes

Revert changes made to your working copy:
git checkout .

Revert changes made to the index (i.e., that you have added), do this. Warning this will reset all of your unpushed commits to master!:
git reset

Revert a change that you have committed:
git revert <commit 1> <commit 2>

Remove untracked files (e.g., new files, generated files):
git clean -f

Remove untracked files directories (e.g., new or automatically generated directories):
git clean -fd
