[Sugar-devel] feedback from a teacher in Uruguay

[Andrés Nacelle]

Hello you all,

In first place thanks for asking, 'm glad to try to help here.

Well, lets see. I think in first place we need to make sure witch is the
version of the SO and firmware on the XO from the teacher and children,
which is really easy for the teacher to tell us. There's a chance that she
(or some student) have an activity called something like "Info XO", in that
case they just have to run it and the info will be displayed. In case she
doesn't have it she needs to pres the "tick" button on the game pad during
the booting for the firmware and after the booting change to a terminal an
there look for the SO version.
Once we have that info we can start to see if we can do something about the
mesh issue.
Independent of this, we never been able to share activities on the mesh for
more than a few XO, trying with 20 no XO shared a thing, not even one.

On the other topics I have nothing to say different from what has been said
in the mailing list.

Thank

Andres Nacelle
