That one needs an openmoko build system, and to create one you need many
hours and gigabytes of free disk space. maybe not the preferred way for
a new comer?

I wrote up what I learned, and with ~15 minutes (flashing included) I had a
python hello world on my moko:

but of course writing in C has certain advantages, so the link Thomas
posted is valid and the investment in a local openmoko build system might
be worth your time.

I agree. but while I don't know what my application will look like at the
end, creating some prototype and example code is much faster done in
python. Later I can rewrite some or all parts in C.

still it would be good to have some examples of nice working application
designs for mobile phones. for example in the android video I saw they
require each gui app to save the state with some system daemon when it is
not on top and the system daemon can kill it whenever it wants.
I wonder if a similar design would be nice for moko? what is the current
strategy? hope not to run out of memory, and if we do the linux oom handler
does it job (we hope it kills the right app)?

still that is very welcome. I now found out how easy it is to get started
with python and gtk, so I hope I can create some app too :)
