Getting your environment set up

It is important that you are comfortable working from the command line in this class. If you are not comfortable working from the command line, and using git, then I would recommend you check out the following:

Because we will be installing a lot of third party packages, and because a big part of web programming involves using and installing 3rd party packages you will each need your own installation of Ubuntu Linux. This is a very common development environment as well as a common environment for deploying production ready web apps.

Unit 2 - Back End with Flask

The Flask Mega-tutorial is an excellent resource for this part of the course.
