[Noisebridge-discuss] [sudo-discuss] using a rasp-pi or a beagle with a Teensy/Arduino microcontroller

I'm thinking more about the semi-default level of interrupt programming
that is inherent in the OS itself.  If I just code with python on the linux
side, I have some level of interrupt programming already baked in from the
linux kernel.  I don't need to be absolutely real-time for the interrupts
but would like to be more real-time for the Arduino micro controller side,
just mostly trying to figure out if there is a simpler way to skin this
cat, as the old saying goes.
