Well, python is known to be slow.
There is plenty of CPU on the OpenMoko for something like Lua.. or
lisp, or scheme
might look into Chicken Scheme: <http://www.call-with-current-
It runs on the Nokia 770: <http://chicken.wiki.br/chicken%20on%
20handhelds>, and the Zaurus, both of which have less CPU
than the Neo1973.
Chicken Scheme compiles to 'C'. Its fast, way faster than Python.
One of the more recent additions to Chicken is the 'Easy Foreign
Function Interface'. This enables you to embed C or C++ code inside
your Scheme code and it gets converted to Scheme automatically. The
example given in the manual <http://chicken.wiki.br/easyffi> or
Chicken Scheme to write a Qt application. The Qt classes get
automatic wrappers generated using the object system (TinyClos). So
the actual Scheme code looks like:
(define a (apply make <QApplication> (receive (argc+argv))))
(define hello (make <QPushButton> "hello world!" #f))
(resize hello 100 30)
(setMainWidget a hello)
There is a GTK SWIG for Chicken: <http://wiki.freaks-unidos.net/
Someone should also look into putting Einstein <http://
www.kallisys.com/newton/einstein/> the NewtonOS port on the Neo1973.
It already runs on the
Nokia 770 and the Zaurus.
