Martin Dengler:
"Since you don't know if J can run on the XO, J is not a good thing to
recommend for developing activities on the XO, right?"
Wrong. J is worth investigating. J is so cross platform and so powerful
that it is a lifetime useful tool for teaching and for thought.
J, like APL, sadly does not get the publicity that it deserves.
I would not be surprised if Roger Hui were willing to create an
implementation of J for the XO if that were necessary.
