Re: relax in the cloud ? -- November 23, 2015 - 13:20

Hi Troels,

I have seen that solution before, but I don't believe that Jupyter is
the ideal solution.  It will create an interface for relax that is
very much like mathematica/maxima/etc.  So it is more like a graphical
prompt UI as a web interface.  I think I'd prefer to have much greater
control and create a pure web interface
(https://wiki.python.org/moin/WebFrameworks/).  For example Django was
one that is quite often used (https://www.djangoproject.com/).  That
way the entirety of the screen is dedicated to relax, and we can have
fine control over the execution of the backend.  It would be far
easier to support the automatically created user function system as
well.

Regards,

Edward
