Pip is a package manager of python. You can download Python libraries from some Python repositories like PyPI. You can also download libraries from a git repository. This is gonna be the issue to be explained in this article.

I don't like to memorize things all the time. So, I guess, I couldn't be working without internet :). Whenever I need to install some python libraries from a git repositories, I see a lot of way to do it. It is really confusing. This should be the reason why I can't memorize it. I can see how a very simple requirement is handled with to many confusing way. There shouldn't be to many way. Some of them is not working neither. At last, I decided to blog it.

As you may know, you can use two protocols which are http and ssh to do something on git repositories. Using protocol ssh instead of http may provide some ease of use. Because of nature of ssh, you can do something with your primary/public keys. So, you don't have to input your credentials all the time. But I'll be

Need to sync a fork with the main repo?

Preserving Your Work on JupyterHub

This week we're using a great service called JupyterHub, which allows everyone at GeoHackWeek to learn using the same computing environment. However, though you can edit the files and experiment with the the tutorial_contents repository that your personal jupyterhub contains, you won't be able to git push immediately. This is because the default version of the repo points to the geohackweek version on GitHub, and not your personal version.

Simply put: you might want to save your work. Here's how.

1. Open A Terminal on JupyterHub.

Navigate to https://jupyterhub.geohackweek.org/. Find the New dropdown menu, and click Terminal.
