Getting involved

[James Cameron]

G'day Barry,

Thanks for your question.

One Laptop per Child continues to produce the XO laptop for deployment
in school systems.  They use the Sugar learning environment on Fedora
Linux.  The latest model can also run the Android operating system.

To get involved at an application programming level on Sugar, join
with the Sugar Labs organisation.  See http://sugarlabs.org/ and their
mailing lists.  Plenty of opportunity there.

There are some volunteer opportunities at the moment if you are a
system programmer with Fedora Linux experience, and this is the right
mailing list for that.

I can only speak for the technical side, sorry.  I'm a contractor to
One Laptop per Child.
