Cheat Sheet SBT

To install sbt in OS X run brew install sbt (requires the almighty Homebrew installed first).

Basic commands are the following:

Command	Action
Deletes all generated files (in the `target` directory)	`clean`
Compiles the main sources (in `src/main/scala and src/main/java` directories)	`compile`

brew install python3

pip install cookiecutter # command-line utility to create projects from cookiecutters / project templates
pip install numpy # vectors and matrices in Python
pip install scipy # other scientific computing tools
pip install pandas # dataframes in Python!
pip install jupyter # notebook

What this?

So one of the painful points of using docker on OS X is that you need to run a virtualbox VM, which often suffers from performance issues. With xhyve, a OS X virtualization system, and docker-machine-xhyve you can now have docker use the native OS X hypervisor to run containers.

No more dealing with virtualbox shenanigans!

In this script, I've also set up a way to autoconfigure terminal sessions to load docker's environment vars (dependent on docker-machine) so you do not have to run eval $(docker-machine env whatever) every time you open a new terminal window.
