Hi,
Bert has found some snafus in my documentation which I hope we can get
straightened out.
Actually, this version of Learn will work as well with an SD card since
they appear the same to the software.
Keep in mind, that a deployment of Learn will need a school server, at
least in the developing world. In the US many students have a computer
lab at school and their own computer at home. However, this is not the
case in Rwanda.
Learn is designed to download lessons from the school server that
students can work on at home (and upload the results when they connect
again). The USB key is to allow people to test it without having to set
up a school server.

I think there is way to set up an SD card to be used at runtime by
pointing to it in the Journal where items appear as if they were
actually on the XO. This should also work with an usb drive. I was
walked through the procedure by Scott Dowdle of Montana State
University. It didn't stick with me... he's a great teacher, but I'm a
so-so student. I'll cc this note to him. Maybe he can jump in with some
ideas for you.

P.S. Scott... I still could like to learn how to do this!

Subject: Re: [IAEP] Learn activity
So you're talking about this page:
http://wiki.sugarlabs.org/go/Activities/Learn
I indeed encountered other issues.
You should warn people that your scripts not only install firefox in
/opt, but also modify /usr/lib/python2.7/SimpleHTTPServer.py and
/usr/bin/sugar-launch.
You should not tell people that the USB drive replaces the
schoolserver because the USB is not used at all at runtime. It's simply
one way of installing your stuff.
Your setup instructions on the website do not work. Besides of the
broken formatting, the commands, if typed literally as given, do not work.
They're also outdated. There is no firefox-11.0.tar.bz2 on
mozilla.org. Only the current version is available for download
(firefox-13.0.1.tar.bz2) but with that, your Firefox.sh would not work.
Running the activity modifies the activity directory (creating
symlinks, copying contents etc.). That's verboten (under Rainbow,
literally so).
Your activity expects the content in ~/Documents/karma. Your
instructions/scripts do not put it there. And if they did, the activity
would try to copy the whole content tree on every launch.
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.
So how is this supposed to work? Don't give me scripts, but explain,
please. I jumped through all these hoops because I really wanted to see
it working.

Hi,
Thanks for pointing this out. We always seem to miss the obvious in
documentation.
The website I am referring to is the one linked from activity page
on ASLO.
This version uses a usb drive to stand in for the school server.
The first time Learn is launched it must be connected to the school
server to download the initial content. If not, the user gets a message
saying it must be connected to the school server. Apparently, this isn't
handled correctly when starting without the usb drive (or a school server).
The webpage linked from the activity screen gives information on
how to set up the usb drive. Since Learn wraps Firefox, it needs to be
installed. On recent builds with Gnome desktop, Firefox is installed,
but Learn works better with versions from 4 up and so needs to be
reinstalled. The web page provides scripts to handle all of this,
hopefully, for non-developers.
Please let me know if you encounter other issues.
Thanks,
Tony

Hello,
Today, Version 51 of the Learn activity has been posted to
Activities.Sugarlabs.org. This version is intended for use
by deployments to evaluate its usefulness in their context.
It has a separate (45mb) file of content which can be downloaded
from the website. The website also has installation instructions.
Which website?
When I run this on an XO-1.5 @ 885, it opens a Firefox window (not
full-screen) with an error message (connection error, laptop not
registered) and a blank icon in the frame. Additionally, there is the
Learn icon in the frame, but clicking it says the activity could not be
started.
