The DockerFile instruction VOLUME [ "/data" ] creates an anonymous volume mounted as /data that allows just 1 container to use it (unless you issue a docker run --volumes-from or bind mount it with docker run -v /var/lib/docker/volumes/9283:/data) until you docker rm that container. After docker rm, the volume remains but it's inaccessible by containers without a bind mount.

So, I asked a question on Math.StackExchange.com, and although I never received a response, I think that my sketch, shown below, is roughly accurate:

For a long time, I had been curious what an IPA to speech sounds / MP3 audio converter would sound like. Google doesn't list any free tools. So today, I wrote a free converter in Python. The code is extremely basic and not a good example of programming, but it does illustrate the point of why so few converters probably exist: the results are nearly worthless--at least, when using such simple logic (i.e., just play each IPA sound in order as transcribed).

If you'd like a black background for OneNote, you can buy OneNote Gem (which is fantastic), or you can download a free OneNote 2010/2013 formatted section whose background is already black.
