Hi Douglas,

Thanks a lot for the write up. Just scanning through the recent activity 
on this list I see that you have been making an impressive impact since 
you started! It's making a big difference, keep it up.

Can you put this feature on the roadmap: 
http://wiki.laptop.org/go/XS_Roadmap

link to it or put it wherever it belongs in terms of the target release 
with this functionality.

Can you explain the user experience on the XO for this feature? That is, 
user (or someone prepping XOs before distribution to the field?) opens 
XO and turns it on. Is that all they have to do or do they need to click 
the register menu option?

How do they know when the registration is successful from the XO side?

Who is the lead customer for this feature? I can help socialize it and 
see who is interested if you don't have a first target customer yet. I 
think it will be useful but I want to figure out who we should run the 
design by for verification.

What versions of SW on the XO is required? Maybe it works with 656, 703, 
708, 711 and 8.2?

You may want to just add those details to the Readme and post that to 
the wiki for the record.

Thanks,

Greg S

XS Activation Server


This package allows the school server to activate laptops over the
network, and to import activation keys via USB.

Initially the server will not know any activation keys, so you need to
have a USB stick containing OLPC activation leases before this is much
use.

Activation Server
-

The server listens on port 191 of the 172.18.0.1 interface.  The
laptops, during boot up know to look there.  Each laptop sends its 11
character serial number.  If the server has the activation lease for
that laptop, it sends it in reply.

With XS 0.4, special steps are necessary to get this working properly
(see below).

Importing leases from a USB stick
-

The leases should be in a file called 'lease.sig' in the root
directory of the USB stick.  The format and location of this file is
exactly what you would use to activate a laptop directly via USB.

Plug the USB stick into the server and wait a few seconds.  With XS
0.4 the only clue as to the progress of the transfer is written to
/var/log/user.log.  With later systems, if the server beeps when the
USB stick is inserted, it will beep again when the transfer is
complete.

XS 0.4 caveats and special instructions
---

The activation server will not work on XS 0.4 until the network has
been reconfigured slightly.  The steps to take are:

#1. Copy ifcfg-br0:0 (in this directory) to
/etc/sysconfig/network-scripts/ifcfg-br0:0

   mv ifcfg-br0:0 /etc/sysconfig/network-scripts/

#2. Restart the bridge.

   ifdown br0; ifup br0

#3. Test it with:

   ping 172.18.16.1

If the ping works, so should the activation server.  To test the
network from a laptop, ping 172.18.0.1.

With 0.4, you will also not hear beeps when the USB transfer starts
and finishes.  The workarounds are to read /var/log/user.log, or to
wait a long time.

Re: Write Collaboration - what is known to work / what is, not? (J.M. Maurer)

Hi Marc et al,

This is a timely discussion as we are trying to figure out and document 
exactly what write collaboration will be supported for end users in 8.2.

The target use cases are:
http://wiki.laptop.org/go/Use_Cases#Write
http://wiki.laptop.org/go/Use_Cases#Uruguay_Teacher_Example
http://wiki.laptop.org/go/Use_Cases#Collaboration_Use_Cases_from_Peru

Basically, we want several students to open write and share the same 
document. They should each be able to edit it and each should be able to 
save an interim local copy at any time.

We want to know what is the scale allowed for that (e.g. 2, 4, XOs). We 
can restrict the things they can do if we know and document that in advance.

Are you saying that the initiator of the write document must not close 
it or the sharing will stop? If that's the case for this release we can 
document that and user can probably work around it.

Can any participant save (Keep) the document at any time?

Martin,

Go ahead and burden the bug database with these. We want to get this 
right, eventually. Also, update the use cases if you think I missed 
something there.

Sharing write could be our strongest collaboration activity and it has a 
lot of interest from the field. Let's make sure we can say what will 
work in this release then we can extend it to more areas in the next 
release.

Thanks,

Greg S

In brief things work for the simple case, but for example

There is no UI indication that things have changed.

Yes, see my reply here: http://dev.laptop.org/ticket/8160#comment:2

It's *far* from trivial, so given that I'm implementing this in my spare
time, I can't give a timeframe yet.

 - Should invitees keep a copy in their journal and be able to 
resume
it in private?
   
  
   I'm not sure to understand what you mean here.

If i understand correctly, this should already work. Every collaborator
will get an entry in his/her journal automatically.

Re: [Techteam] Weekend Report - due today

Hi Tomeu et al,

FYI this is a piece of my weekly report that I write for my manager and 
the engineers working for OLPC (aka techteam). Its sometimes picked up 
by the community news.  It just says what I did last week and what my 
goals are for next week.  I hope to send it to this list too in the 
future.

Cmap tools (http://cmap.ihmc.us/) is a client server application that 
appears to have pretty good traction in schools, mostly in South 
America. We have a request to make it work on the XO. I exchanged some 
e-mails with Alberto Canas (con enye) who is the main application owner.

There are three main challenges to making this work on the XO:
1 - It runs on Java. (I asked about Java on a list for that reason, but 
I asked about Java in the browser. In this case its just Java VM).
2 - It uses multiple windows.
3 - Its free but not open source.

The first point seems solvable if they just install Java afterwards. 
Then we don't need to worry about licenses. Its a big install but 
probably not a deal breaker. The performance may be challenging but 
again I think we can make it fit.

The second point is a tougher problem. Alberto thinks they could 
re-write the application to work with tiled windows so they all fit on 
the XO. The other idea I have heard is that we could run an activity 
which is X-Windows. Then you could launch this activity within that one. 
That may affect performance and would need testing. For the first idea 
of rebuilding the Cmap tools for sugar, we would need engineers to work 
on that which brings me to the third point.

I'm not sure what free but not open source means. I think it means that 
we can not take a snapshot of their code and fork it nor can we modify 
it and push it back to them. We need to find a way for Alberto to hire 
more engineers if we want them to improve the implementation for the XO.

The only good idea so far is the X-windows in Sugar idea.

I'm open to other suggestions on this. Questions and comments welcome too.

I know of one opportunity in Latin America which is being held up by 
this. There may be more in the future, we'll see. The pedagogical 
specialists here tell me that concept maps are pretty hot in education 
right now. They also pointed me to a commercial tool which some schools 
use: http://www.inspirationsoftware.com/

Does anyone know of an open source solution in this area?

If the customers want cmap tools, my first choice is to make that work. 
That's what I'm focusing on right now albeit lower priority than 
shipping 8.2 :-).

Thanks,

Greg S

The open source project is on http://dev.chromium.org.
There are instructions for a Linux build, but it has the following warning:

Note: There is /no/ working Chromium-based browser on Linux. Although 
many Chromium submodules build under Linux and a few unit tests pass, 
all that runs is a command-line all tests pass executable.


Anyway, since it really targets the high-end (each tab running its own

I doubt it will run nicely on the XO.

Re: Google Chrome activity?

2008-09-03 Thread Jim Gettys

I would not presume that Google Chrome's memory usage is worse than
existing browsers (though thankfully firefox 3 has recently lowered the
bar a lot); it has the advantage of throwing away entire address spaces,
avoiding some of the memory fragmentation problems that have bedeviled
other browsers.

So I'm taking a wait and see attitude.  But first, let someone else
do the basic Linux port, and then we can measure

bounce works fine in that build -- performance and audio are very
acceptable.  there's still mouse cursor flicker, i think related

Re: Freeze?

Hi Marco et al,

I think you are doing the right thing by proceeding as usual until we 
get the word that a harder freeze is in place.

FYI for all on triage. We are caught up as of yesterday at 3PM US ET.

We will do a triage everyday at 1PM US ET on IRC (freenode.net 
#olpc-meeting channel). We quickly look at each bug and either mark it a 
blocker, change its milestone to a future release, ask for more details etc.

I think all the blocks?:8.2.0 bugs have been cleared. Some were 
upgraded to blocks:8.2.0, some were resolved and some were downgraded.

So we are now focused on the single query: http://dev.laptop.org/report/28

If we can clear those we will be ready to release (assuming no more deal 
breakers come in...)

FYI on meetings we also have a two weekly meetings on this release at 
the same IRC location. Tuesdays and Wed.s 2 - 4 PM US ET.

Those meetings cover bug triage, release process, state of the code and 
anything else needed to get the release out the door.

Thanks for all the test reports and work.

Thanks,

Greg S

Interesting question.   I've heard lots of requests for this, but
all trials use pre-activated laptops.   Uruguay activates laptops as
part of the software installation process, as does Peru.

 What versions of SW on the XO is required? Maybe it works with 656,  
 703,
 708, 711 and 8.2?

 You may want to just add those details to the Readme and post that to

 XS Activation Server
 

 This package allows the school server to activate laptops over the
 network, and to import activation keys via USB.

 Initially the server will not know any activation keys, so you need to
 have a USB stick containing OLPC activation leases before this is much
 use.

 Activation Server
 -

 The server listens on port 191 of the 172.18.0.1 interface.  The
 laptops, during boot up know to look there.  Each laptop sends its 11
 character serial number.  If the server has the activation lease for
 that laptop, it sends it in reply.

 With XS 0.4, special steps are necessary to get this working properly
 (see below).

 Importing leases from a USB stick
 -

 The leases should be in a file called 'lease.sig' in the root
 directory of the USB stick.  The format and location of this file is
 exactly what you would use to activate a laptop directly via USB.

 Plug the USB stick into the server and wait a few seconds.  With XS
 0.4 the only clue as to the progress of the transfer is written to
 /var/log/user.log.  With later systems, if the server beeps when the
 USB stick is inserted, it will beep again when the transfer is
 complete.

 XS 0.4 caveats and special instructions
 ---

 The activation server will not work on XS 0.4 until the network has
 been reconfigured slightly.  The steps to take are:

 #1. Copy ifcfg-br0:0 (in this directory) to
 /etc/sysconfig/network-scripts/ifcfg-br0:0

mv ifcfg-br0:0 /etc/sysconfig/network-scripts/

 #2. Restart the bridge.

ifdown br0; ifup br0

 #3. Test it with:

ping 172.18.16.1

 If the ping works, so should the activation server.  To test the
 network from a laptop, ping 172.18.0.1.

 With 0.4, you will also not hear beeps when the USB transfer starts
 and finishes.  The workarounds are to read /var/log/user.log, or to
 wait a long time.

On 3 Sep 2008, at 13:36, Greg Smith wrote:

 Cmap tools (http://cmap.ihmc.us/) is a client server application that
 appears to have pretty good traction in schools, mostly in South
 America. We have a request to make it work on the XO. I exchanged some
 e-mails with Alberto Canas (con enye) who is the main application  
 owner.

...

 The first point seems solvable if they just install Java afterwards.
 Then we don't need to worry about licenses. Its a big install but
 probably not a deal breaker. The performance may be challenging but
 again I think we can make it fit.

 The second point is a tougher problem. Alberto thinks they could
 re-write the application to work with tiled windows so they all fit on
 the XO. The other idea I have heard is that we could run an activity
 which is X-Windows. Then you could launch this activity within that  
 one.
 That may affect performance and would need testing. For the first idea
 of rebuilding the Cmap tools for sugar, we would need engineers to  
 work
 on that which brings me to the third point.

 I'm not sure what free but not open source means. I think it means  
 that
 we can not take a snapshot of their code and fork it nor can we modify
 it and push it back to them. We need to find a way for Alberto to hire
 more engineers if we want them to improve the implementation for the  
 XO.

 The only good idea so far is the X-windows in Sugar idea.

 I'm open to other suggestions on this. Questions and comments  
 welcome too.

 I know of one opportunity in Latin America which is being held up by
 this. There may be more in the future, we'll see. The pedagogical
 specialists here tell me that concept maps are pretty hot in education
 right now. They also pointed me to a commercial tool which some  
 schools
 use: http://www.inspirationsoftware.com/

 Does anyone know of an open source solution in this area?

I'm a bit of a mindmapper/diagrammer type. If you're looking for free  
and Open Source you want to look at freemind. It's very competitive vs  
the commercial mapping tools and also supports a number of external  
file formats, it's another Java app so would need that extra install.

http://freemind.sourceforge.net/wiki/index.php/Main_Page

The other tool worth a poke is the more general purpose graphviz, also  
free and Open Source, it's command line but there are some GUI's out  
there also. Could be a very nice Activity to wrap a simple GTK GUI  
around the tool chain:

http://www.graphviz.org/

Also want to point you to the Model activity if you've not tried it.  
It's rough and incomplete at my last testing, but seems to be a  
potentially interesting diagramming tool. The wiki talks of easily  
sketch and simulate system dynamics models which seemed a pretty  
scary opening paragraph – I'd be happy with just a good diagramming  
tool :-) Dev work seems to have gone quiet :-(

http://wiki.laptop.org/go/Model

 If the customers want cmap tools, my first choice is to make that  
 work.
 That's what I'm focusing on right now albeit lower priority than
 shipping 8.2 :-).

however, it also seems that this google EULA covers their

the case that one could build an equivalent browser using google's

Touchpad improvements and activities using pointer (mouse) motion....

2008-09-03 Thread Jim Gettys

Richard Smith has fixed some bad performance problems in the embedded
controller, that talks to the touch pad, now in the latest firmware in
joyride and the 8.2 stream.

The consequences are that the touch pad is reporting many real mouse
motion events, as you move your finger on the touch pad.  These were
previously getting dropped on the floor in 8.1 and before, and causing
many of our touch pad behavior problems.

This improved behavior, strangely, can pose performance problems for
incorrectly written activities that ask for mouse motion events; paint
programs are a classic example. If you can't keep up with the rate at
which pointer (mouse) motion events are delivered,  and you get more
events, your application can fall further and further behind, causing
bad laggy behavior.  Having improved our touchpad, we're now exposing
some of these issues due to the increased number of events.

In days of yore on slower machines this was a common problem, so the
window system has provisions for it.  Many current developers on fast
machines do not see this often on current fast desktops/laptops, so it
many have forgotten about the solutions.

X has what is called mouse motion compression; in the GTK toolkit, it is
invoked by:

The gtk.gdk.POINTER_MOTION_HINT_MASK is a special mask which is used to
reduce the number of gtk.gdk.MOTION_NOTIFY events received. Normally a
gtk.gdk.MOTION_NOTIFY event is received each time the mouse moves.
However, if the application spends a lot of time processing the event
(updating the display, for example), it can easily lag behind the
position of the mouse. When using the gtk.gdk.POINTER_MOTION_HINT_MASK
the server will only send a single gtk.gdk.MOTION_NOTIFY event (which is
marked as a hint) until the application asks for more, by calling the
gtk.gdk.Window.get_pointer() method.

You can find the full description in
http://www.pygtk.org/docs/pygtk/class-gdkevent.html

Techniques for handling the issue:
1) by far the best approach, when possible, is to make your pointer
(mouse) handler very light, then do recomputation and drawing in an idle
handler
2) The get_pointer technique using the above POINTER_MOTION_HINT_MASK,
to poll at the rate your application can keep up. But best is to drop
the result from get_pointer() on the floor and forget that it's
overloaded in the X protocol and just pretend that you called
GiveMeAnotherEvent
3)  Another technique, rather than doing get_pointer, is to peek in the
event queue to see if the next event is also a pointer motion event, and
use the later event if it is still a pointer motion event, using
gdk_event_peek.

My thanks to Owen Taylor for refreshing my cache and telling me the GTK
idioms.

Note that X also has a facility to record the full stream of mouse
motion coordinates as well, if you want the precise timestamped path the
pointer followed between events.  The XGetMotionEvents call can be used
to get that path, at whatever hardware resolution the hardware was able
to provide.  Note that the X server/driver may have compressed some
sequential motion events together to begin with.

http://freemind.sourceforge.net/wiki/index.php/Main_Page

 The other tool worth a poke is the more general purpose graphviz, also
 free and Open Source, it's command line but there are some GUI's out
 there also. Could be a very nice Activity to wrap a simple GTK GUI
 around the tool chain:

http://www.graphviz.org/

 Also want to point you to the Model activity if you've not tried it.
 It's rough and incomplete at my last testing, but seems to be a
 potentially interesting diagramming tool. The wiki talks of easily

 scary opening paragraph – I'd be happy with just a good diagramming
 tool :-) Dev work seems to have gone quiet :-(

Re: [Server-devel] xs-activation: why no IPv6 yet?


IPv6 was supported in earlier builds.

It was taken out last December, as there was no clear way to
support IPv6 when multiple school servers are providing
network access through the school mesh.[1]

As we don't support multiple school servers with a school mesh
(and probably will never), this can be restored.

wad

[1] The reason is that the mesh firmware supports a level 2
anycast MAC address.   Only one of the responding DHCP
servers is listened to for an address assignment.   IPv6 RADVD
includes unsolicited route advertisements, which would be
picked up by all laptops in a school, causing them to be very
confused about which gateway they should be using (in IPv4
the firmware selects the DHCP response from the closest gateway.)

On Sep 2, 2008, at 1:21 AM, Douglas Bagnall wrote:

 To preempt this FAQ, the F7 school server is quite inconsistent in its
 IPv6 support, and some work would have been necessary to get it to a
 state where I could test it.  With the immanent jump to F9, and a new
 networking setup, this didn't seem very worthwhile.  I'll revisit it
 again when IPv6 is working on the school server in general.

 The activation server hides behind xinetd, so it doesn't deal directly
 with networking.  Getting it to work with IPv6 shouldn't be more
 difficult than it is for anything else in that situation.

[Server-devel] Activation Key for G1G1 Xo's

How do you activate XO computers purchased through the G1G1 program?  I have
purchased 45 XO's through eBay that are now being used in an orphanage in
the Philippines.  Students have access to the Internet through an AP but we
have not been successful in configuring the XS to recognize the XO's.  

 

I also have 4 XO's purchased through the G1G1 program.  I have setup an XS
server with an AP successfully but can't get the XO's recognized by the XS.

This means that they should never require an activation key.

What software build is on the laptops ?
What XS build are you using ?

When you say you can't get the XOs recognized by the XS, exactly
what do you mean ?
1 - Do they receive a DHCP address ?
2 - Does access to the Internet through the server work ?
3 - Does registration work ?
4 - Does ejabberd see the laptops as registered ?
(Go to https://172.18.0.1:5280/admin )
5 - Does ejabberd see the laptops as online ?

If 4 or 5 is the problem, did you set up the shared roster for  
ejabberd ?

Re: Cmap tools (was [Techteam] Weekend Report - due today)

Hi All,

Thanks for all the pointers to concept maps. Its impressive how many 
options exist. I can see how they fit well with Piaget and other 
learning theories.

However, my immediate challenge is figure out what it will take to 
support cmap tools on the XO.

Has anyone tried making the activity which is X-windows and inside which 
other activities can run?

Any other ideas on how to make an app which uses multiple windows (and I 
believe allows drag and drop of data from one to the other) work on the XO?

There seems to be some major differences in the GtkDrawingArea

Btw, ignore the GtkDrawingArea - Pixbufs readings - I realized that
the pixbuf to be displayed was not in the XO.

Hey,

I just installed 2385 and wanted to run the cool Map activity (
http://wiki.laptop.org/go/Map_%28activity%29) in order to demo it at FUDCon

Unfortunately the activity seems to hang at startup and gets killed after
about 30 seconds or so with the Map icon remaining below the XO on the
home-view.

Any ideas?

Trac ticket workflow updates.

2008-09-03 Thread Michael Stone

Friends,

As we wind down toward the end of the 8.2.0 release cycle (and begin to
tighten our change control), we must make a few tweaks to the Trac
ticket workflow. I have written up the new workflow in great detail at

  http://wiki.laptop.org/go/Trac_ticket_workflow

The highlight is three new 'action needed' states: 

   'approval for release', 
   'add to release', and 
   'test in release'

whose meanings are, I hope, apparent.

Please reply with any resulting questions, comments, suggestions, or
gripes. (Oh, and please help fill in the linked-to pages!)

i reverted a machine to joyride 2212, which, as indicated in #7787, was

bounce works fine in that build -- performance and audio are very
acceptable.  there's still mouse cursor flicker, i think related
to the continuous frame-rate display in the corner.  but in newer
joyrides the whole screen is choppy.
   
   Did you typo browse for bounce in the subject?

 Who's we?  According to my recollection, the Geode LX docs indicate that
 the GPU supports one accelerated 48x48  sprite with 8-bit alpha for the
 cursor.  Did we all misread the doc? Is the doc wrong? Is the feature
 missing in the driver? What about the Windows driver?

Oops - I sliped into GX mode there for a while.  Yes, the GPU does

XO

2008-09-03 Thread Henry Vélez Molina

Hola a todos.
Les comento que hemos venido trabajando con las laptops desde hace 3 meses
y hemos encontrados algunas anomalías técnicas.

Quisiera saber si esto se les ha presentado y si conocen las posibles causas
o soluciones.

1. Mousepad rebelde. Se mueve bien, pero al soltarlo cambia su posición. Por
obvias razones no permite el control de la XO.
2. Deja de detectar la batería. Esto se soluciona cambiando la batería. Pero
no conocemos la causa de este error.
3. No reconoce el cargador. Al iniciar la máquina se muestra un mensaje en
donde se dice que le cargador no está presente.
4. Se desconfigura la fecha y bloquea la XO porque la lease no es válida.
Esto se soluciona activando nuevamente la XO y modificando la fecha. Pero
aun no conocemos la causa concreta de este error.
5. La XO no bootea. Se inicia la imagen del boot-anim, y no avanza más. Si
se formatea, el error desaparece. Causa aun no conocida.

Gracias por su cooperación.
Estamos en contacto para trabajarle a esto.

Saludos.

Using bridges and interrupt load

In the XS networking infrastructure we sometimes setup a bridge with
an IP address and netblock (as you would with an interface) and then
if-and-when the HW interface comes up, we assign the interface to the
bridge.

This is a technique used quite a bit on projects like OpenWRT where
the main purpose of the device is routing. We use it because we want
to associate dhcpd to devices that come and go (the USB-plugged active
antennae) and if we let dhcpd bind to the IP address in the bridge,
then we can associate the physical device to it when it becomes
available with no dhcpd restarts.

There is another IP address that we'd like to do the same with - the
master 'school server' IP address, which has to be the same and
available in several (and often dynamically changing) scenarios.

But it is starting to worry me that when we use this technique, the
physical interface is brought up in promiscuous mode, and it is left
to the kernel networking stack to decide what frames are meant for us,
and what frames are not.

On interfaces where there is considerable traffic -- a 1Gb LAN for
example with a cheap non-switching hub -- there could be quite a bit
of traffic not meant for us. This naturally means more interrupts.

What I don't know is whether the amount of noise created this way is
significant for a modern 1GHz i386 cpu that is actually trying to do
other stuff. The OpenWRT boxes are there for routing, if there's a bit
of CPU churn to get the job done, then it's ok.

But the XS is there to provide end-user services -- if interrupt load
can eat its capacity to do useful work, I want to be careful with
these bridges...

Does anyone know more about the irq load caused by this technique?

cheers,

*Fantastic*. After seeing your logo, I started thinking of where
would we put a logo - a quick rundown of the spots I think we'll have
one...

 - sticker on the case of my test XSs :-)

 - grub background at boot time during install and normal boots

 - installer splash screen (if I fail in my quest to remove the
graphical anaconda 8-) )

 - logo on web-based tools - we'll be using initially moodle and
mediawiki as the 'face' of the XS, so a small, easily identifiable
logo will be good. Will need the little url bar icon. Edges/shadows
with gaussian blur discouraged as it'll be hard to blend on CSS-based
themes... :-)

any others?

ok, initrd works, but lets debug it from the usbkey for now, for the

note: anaconda may fail to find the ks file on the usbkey the first

nobody is using a serial console yet, right?

In an unrelated goose chase, I removed sqlalchemy from idmgr today.

 Hi,
 
 My apologies - I need to do some research on how to setup the 
 repo.or.cz. As an immediate expedient, I have attached the relevant 
 files to this email. When I get a little time, I will set this up 
 properly. The readme tries to describe the files and how they are used.
 

hey Tony, this is a good start. I have a somewhat different workflow in
mind. Here is a narrative that describes what I am thinking

User Story 1: Intermittent School attendance and School Server Outage

Monday
1. Kid goes to class
2. Teacher directs kids Moodle site
3. Kid navigates to Moodle Module for Class 2 math for the current month
4. Kid clicks 'download' link next Moodle module
5. This action downloads a the moodle module as a .xo bundle and
locally installs it to the XO
5.1 Inside the module are readings, pictures, animations, etc. all
available offline
6. School ends on Monday

Tuesday
Kid can't go to school. Mom and little brother are sick, has to take
care of them. Kid opens up XO and offline Moodle activity he downloaded
the day before. He does lessons that show him basic concepts, introduce
him to basic animations using activities like Etoys, and reads
explanations that answer some of the things he doesn't understand.

Wednesday
Kid still can't go to school. Has to help out in the fields. Later that
day the kid spends some time w/ the Moodle module

Thursday
Kid goes back to school. Kid isn't behind the other because he followed
the lesson plan at home. This has social importance that shouldn't be
understated. 

Over night there was an electrical surge that fried the school server.
The teacher can still instruct using the XO because she has it installed
locally as an activity and so do the kids.


The key here is that we need to package each offline moodle course as
an .XO Activity Bundle. http://wiki.laptop.org/go/Activity_bundles

Getting started, we only need the most basic features of Moodle.
Basically page navigation and the ability to display flash animations
and embedded pdfs for the supplementary readings. 

In time we can look at adding more dynamic stuff like access to the
gradebook but that can wait. In Nepal's context, our kids have no
libraries and maybe 4 small coursebooks.

Hope this helps and sorry I haven't been able to provide you w/ more
feedback earlier.

Pls post our correspondence regarding Offline Moodle to the
Server-Developers mailing list.

  Can you put this feature on the roadmap:
  http://wiki.laptop.org/go/XS_Roadmap
 
 It's already there - we're using Trac's status overview searches,
 have a look :-)
 
 
 What happens is that - paraphrasing your email...
 
  someone prepping XOs before distribution to the field opens
  XO and turns it on. That is all they have to do.
 
  Who is the lead customer for this feature?
 
 Peru, Ethiopia. They've been asking for it, we discussed this in the
 last 2 phone meetings :-)
 

It would be be immediately practical in a warehouse setting, where
managing a key with a bunch of activation leases is a pain.

Now to get wireless installation/upgrade ready for use in the
warehouses... all we need is a signed 'nandcast' boot image.
