The code behind the analysis in this blog post.

All the fun stuff lives in the Jupyter notebook.

1. Build the container:

   $ docker build -t gem-vulnerability-analysis .
   

2. Run the container:

   $ docker run --rm \
       -v "$(pwd)/notebooks:/home/jupyter/notebooks" \
       -p 8888:8888 \
       gem-vulnerability-analysis
   

3. Visit the URL that appears in stdout

Running with Docker is probably easier, but that's not your thing:

1. Install Ruby, Jupyter, and iruby
2. Navigate to the notebooks directory
3. Download and extract the contents of the Rubysec advisory database to a sub-directory called ruby-advisory-db-master
4. Run jupyter notebook
5. Visit the URL that appears in stdout
