Externals for Dummies

[hh]

Probably you don't need an external because LC has everything available.
I made a simple stack in 2014 that is kind of an interface to Mathematica/Wolfram
(so you can use one copy of Mathematica locally as 'serving').
Runs on Mac/Win/Linux/RaspberryPi.

It is even fast enough on a RaspberryPi (Raspbian includes a free copy of Wolfram/Mathematica 10). Some people have a "Raspi cloud" serving ...

The stack includes 10 Examples (from plots to producing a table of function values).
