  note         = {{Addendum to the README: running the VM  VirtualBox 
                   ( can be used to open
                   the VM. We are not sure why, but sometimes the
                   machine has trouble loading and gets stuck at a
                   black screen. If you have this problem, try
                   powering it off and on again and also pressing the
                   Enter key when it opens (and select Ubuntu). Once
                   the machine loads, you can then find DiffStream in
                   Files (~/diffstream). Open , which
                   should be identical to this file, except for
                   missing this paragraph. Please note that many
                   tests in this file will print out "WARNING:"
                   statements unrelated to DiffStream, but related to
                   certain dependencies; these can safely be ignored.
                   Finally, for the Tutorial and Step-by-Step Guide
                   below, we recommend using IntelliJ to open and
                   browse source code .java files. It should be
                   installed (search for it in the dash).}},
