To do the exercises in the CSSI curriculum, you’ll need certain programs installed - these might be installed already, but check to make sure!

• Python: Check with python --version from Terminal
• Git: Check with git --version from Terminal
• Text Editor: We have standardized around Atom. Once Atom is installed, check that the Shell Commands have been enabled by typing atom --version from Terminal. If you do not get any output, click Atom->Install Shell Commands in the menu bar.
• Google App Engine SDK: Check that the SDK has been installed - you should have an icon in your Applications. You’ll also need the command line tools. Check that they are installed by running dev_appserver.py it will give a big error message if they are installed, or tell you that it is not found otherwise. Click GoogleAppEngineLauncher->Make Symlinks to install them if they aren’t.
• All work should be saved in a folder at ~/cssi. Try cd ~/cssi - if you get a “No such file or directory” error, create the folder with mkdir ~/cssi, and then cd ~/cssi to navigate there.
