I am glad you were able to get it to work. I am still trying to figure
out a more robust way to do this. Perhaps, I could set up an online site
somewhere (e.g. karma.sugarlabs.org) so that the content can be obtained
from that site (in lieu of a school server).
Those lines in the code are left-overs from a debugging effort. I'll
remove them in learn-52. They actually are 'harmless'.
In saying that the usb drives will not be mounted in /media do you mean
they will be mounted somewhere else or that automount will be disabled?
The problem with Firefox is the same as all previous attempts to provide
a Firefox activity. The parent class, activity.py creates a top-level
window. However, ported programs as Firefox create their own
top-level window. This shows up on the frame as a grey smudge. The
solution is probably a move to webkit; however, the webkit installed on
the Sugar build I am using (852) is not current and does not support svg
The activity is unfinished and has been constantly evolving based on
experience at the deployments. The 'authoring' elements, for example,
are relatively new and untested.
The role button (staff, p4, p5, and p6) allows simulation of the way the
activity works in a deployment. There the students and staff are
identified. Staff can access any lessons on the system and can add or
modify lessons. The students have access only to the lessons for their
level and, instead of the edit button, have a check mark which allows
them to commit the results of an activity and move on to the next.
The only obvious effect of changing the role is that the Laboratory
button is not visible in p4, p5, and p6. You will also see that the
second level menu (showing courses for p4, p5, and p6) is omitted and
the activity moves directly to the milestone ladder.
In the examples in Explore, the first milestone has examples of basic
activities which can be created directly in the activity. The second
milestone are examples of lessons using Sugar activities. The third
(Memorize), fourth (Turtle Art), and sixth (British Council) should
work. Actually, the British Council example does not launch a Sugar
activity. The first will work if ShowNTell is installed. The second,
Quiz example and fifth, Wordsearch example will not work at the moment.
Both of these activities need an update so that they can work with a
bundle loaded from the Journal.
The reason for the green (actually cyan) and blue tops is to show
whether the activity has been downloaded from the usb key (school server).
The unit of transfer from the usb (schoolserver) is a milestone. In the
milestone ladder, the light blue (cyan) color shows a milestone which is
not available on the XO. Clicking on the milestone downloads it. The cap
is then blue. This requires the usb key to be mounted (or a connection
to the schoolserver). However, milestones in blue can be used without
the usb key (or connection to the schoolserver). This is in some ways
the core feature of the activity. It allows the students to take home
their lessons while using the school server to provide the storage
capacity not available on the XO.
The Laboratory is intended for use by teachers (staff). It is not
visible in the student role (p4, p5, or p6).
The easiest way to return to Learn after launching another Sugar
activity (the Khan academy video is played by the Jukebox activity
because at the moment I am unable to get audio with the <vidoe> tag)
is to quit the launched activity (Jukebox). Naturally, you could switch
back to Learn on the frame).
Thanks again for your time and patience. If you have any suggestions for
improving the documentation, install process or the activity, they will
be greatly appreciated. You have already given me plenty to do.

>>> Even after I fixed all that manually, it still does not work. The activity itself fails to start and show anything useful. It appears to only launch the web server and Firefox. In a separate window. Not fullscreen. Firefox shows only a directory listing, not the lessons. Quitting Firefox leaves the web server running.

>> The Explore subject is intended to provide extra-curricular courses which students can study to earn badges. At present it contains examples of various types of lessons including a Khan Academy video and associated exercises as well as a story (with audio) from the British Council. Learn is capable of launching Sugar activities.

> With "ms02" do you mean "Explore/examples/2"? But clicking the green box does nothing. Same for the 3rd box labeled "Khan". The first box has a dark blue top for some reason, the others are light.
> Oh. Trying again the tops now are blue too, and I can get to those lessons. Not quite sure how to get back from the Khan practice though (except for closing the tab). Is this just a local copy of some webpage from Khan academy?
