Switching back to JFFS2 for 11.3.0 XO-1

[Daniel Drake]

Hi,

Unfortunately I haven't made enough progress on the XO-1 ubifs issues
so I'm planning to drop us back to JFFS2 for the first release
candidate of 11.3.0.
ubifs still remains as a very easy build customisation.

The main outstanding problems are that we have some systems which fail
to boot, and that our own partitioning overhead plus the unavoidable
ubifs overhead is really a bit much (over 75mb I think).

Progress is being made on both issues, but won't be ready in time for
the freeze for the release.

XO 1.75 ofw_olpc.c question

[Andrei E. Warkentin]

Hi,

Since OFW is resident, I thought it would be nice to try to enter into
it with something like -

__olpc_ofw(enter, 0, NULL, 0, NULL);

I'm doing this from SVC mode.

Yet this just hangs. Am I doing something that's not supposed to work
by design? Is there any
hardware state that I need to reset into a known state (PIC state
maybe..?) The overall effect
is simlar to invoking arch_reset blindly without setting up identity
map, but I didn't yet try doing this
prior to the __olpc_ofw call so I'm just conjecturing...

Thanks,
A

this works on our x86 laptops (via sysrq), so it's not broken by
design.

i think no one has looked into making it work on 1.75 yet, partially
because much of what one can do from olpc_ofw() (i.e., peek and poke
registers/memory/etc) is available from cforth, which runs permanently
on the service processor, the second core in the SoC.  but it would be
nice to have it work.

Re: [Sugar-devel] Help needed for childrens with physicals limitations / ayuda para niños con discapacidades

[Andres Aguirre]

thanks Walter and Peter for the list of activities to test!
Yesterday we release the first version of mouseCam
http://activities.sugarlabs.org/es-ES/sugar/addon/4487 all the
feedback is welcome!
The marks needed to use the activity are inside the .xo, in the marks folder.
cheers

 it will be great! thank you :)
 if someone knows sugar applications that could be used with mouse and
 are simple it will be great to do some tests, now I'm using sokoban
 that has simple interaction and is very interesting.

 Maze, Memorize, SliderPuzzle, Implode, ...

 Andres:

 I have a contact at Ryerson University here in Toronto who runs the rather 
 large research program which specifically works in the area of human device 
 interaction for technology  for severely disabled children, but he does not 
 currently work with the XO because of the small form-factor.  Would you 
 still like me to forward this to him as he might have some insight for you. 
  He's a big open-source advocate.

 Subject: [Sugar-devel] Help needed for childrens with physi
        cals limitations / ayuda para niños con discapaci
        dades

 Hi all, I want to show you the first working prototype of mouseCAM
 activity, wich is design to help childrens with physical limitations.
 This activity communicates directly with the X server of the
 GNU/Linux, being able to be use in the XO computer with any activity
 or with the sugar system as well as any GNU/Linux with the graphic X
 server system. We are working at Faculty of Engineering, UdelaR,
 Uruguay in a course called NEXO with the aim of developing solutions
 for childrens in a special school here in Uruguay and I am working
 with Lorena, Guillermo and María Emilia to bring solutions to the
 childrens that nowdays can't use the XO computer. I need help, maybe
 people in this list knows about activities with very simple mouse or
 keyboard interaction, that can be used in this context. Also we are
 working in a turtleart plugin, in this case the children show a image
 that corresponds with a block and then the corresponding block
 connects with the last block in the programming area, this will be use
 to develop very simple programs, like draw geometric figures or to
 control the butia robot, but is a great improve for them.

 Hola a todos, quiero mostrar el primer prototipo funcional de la
 actividad mouseCAM, esta actividad está diseñada para ayudar a los
 niños con limitaciones físicas. La actividad se comunica directamente
 con el servidor X del GNU / Linux, pudiendo ser utilizada en el
 contexto de la XO con cualquier actividad o con el sistema de azúcar,
 así como cualquier GNU / Linux con el sistema de ventanas X server.
 Estamos trabajando en la Facultad de Ingeniería de la UdelaR, Uruguay,
 en un curso llamado NEXO con el objetivo de desarrollar soluciones
 para los niños en una escuela especial de aquí y junto con Lorena,
 Guillermo y María Emilia estoy trabajando para aportar soluciones a
 los niños que hoy en dia no pueden usar la computadora XO. Necesito
 ayuda, tal vez la gente en esta lista sabe acerca de actividades que
 requieran interacción muy simple con el ratón o teclado, y que pueda
 ser utilizado en este contexto. También estamos trabajando en un
 plugin turtleart, en este caso los niños muestran una imagen que se
 corresponde con un bloque y el bloque correspondiente se conecta con
 el último bloque en el área de programación, esta se utiliza para
 desarrollar programas muy simples, como sacar geométricas figuras o
 para controlar el robot butia, pero es una gran mejora para ellos.

Memorize - use scenario

[Tabitha Roder]

We have been seeing lots of changes to Memorize and some things are a bit
confusing. I was thinking that it might help to write some scenarios for how
you might use Memorize. So here goes...

In class on Monday the teacher says each student is to make a Memorize game
to help learn the elements of the periodic table.

Two students meet at another students house. They decide to play the game
they made about the periodic table. They each have different games so they
collaborate and play all three games.

On Tuesday in class the teacher says they should each make a Memorize game
that just looks at a set of elements based on whether they are metals or
nonmetals. In doing this task they can edit the existing game or they can
create a new game.
They are then asked to share their games so they can practice different
sets.

On Wednesday the teacher says they should each make a Memorize game that
just looks at solids or gases. They are told they should make sure they save
the game from Tuesday so they will have a bigger set of games to play later.


On Thursday and Friday they are given time to share and play the games they
have been creating with their classmates.
