Here's a few more misc. plays around school building shape. Maybe I'm being too 
literal here and should stray more down the server/resource aspect, rather than 
a school aspect? Shout if you think one works better than others (or some 
specific feature):

[Sugar-devel] Sugar Digest 2010-06-28

[Walter Bender]

===Sugar Digest===

1. Between World Cup matches, I have had a busy, but fun-filled June.

The month began with POSSE Worcester, organized by Mel Chua. Mel,
Peter Robinson, and I spent five days with about a dozen computer
science professors from Johns Hopkins, Clark, Union, University of New
Hampshire, and Worcester State in a workshop that covered everything
you need to know to become a FOSS developer. We used Sugar as our
example and walked them through how to modify an activity: everything
from cloning a project on git.sugarlabs.org to requesting a merge to
updating the wiki. They really got into it and over the course of the
week, some significant patches were contributed to Abacus, Measure,
and Physics. It was a bit unsettling to have all of these CS
professors digging deeply into my code (Abacus), but in fact, they
taught me a lot. (I think we should recruit engineering faculty to
review patches). Mel organized a great week and I think the
participants will undoubtedly generate interest in their students in
FOSS and Sugar when classes resume in September.

At the end of the following week, I headed south. I made a quick stop
in Miami in order to pick up a visa for Paraguay. I spent four days in
Asunción and Caacupé with Bernie, Raul, Cecilia, and Paraguay Educa
team. I got a chance to catch up with some old friends and meet
face-to-face for the first time many people I had only met in IRC.
Caacupé, about one-hour east of the capital, is the site their pilot
deployment; I had a chance to visit two schools and meet many
teachers, students, mentors, and even some parents. (The parents were
attending a workshop at one of the schools where they were learning
about the Sugar Journal. They voiced one complaint: the children don't
give them enough time on their computers!) The children were quite
proficient with Sugar and it was integrated into many classroom
activities. The teachers weren't asking how to use the computer – they
had mastered that; rather they were discussing how they could best use
Sugar for learning. My one disappointment was observing a Scratch
project where the children were using sensor input to control their
animations. It was clear that they had not made the connection between
their actions in the physical world and the reactions of their
avatars. My hypothesis is that Scratch is abstracting away too much of
the detail. A quick demo of Measure made the connection much more
tangible. (I need to finish the rebase to GST-Mixer in order to get
Measure working again on the OLPC XO 1.0 hardware.) Over the weekend,
Raul and I watched futbol: Paraguay vs Slovakia. Whenever Paraguay
scored, the crowds in the street jumped up and down, shouting: "If you
are not jumping, you must be Argentine!" Between goals, we spent time
with Patica and the learning team discussing tactics for deeper
engagement into powerful ideas by teachers and students.

The following Monday, I gave a Turtle Art workshop to the teacher
facilitation team. We covered a lot of ground – they each prepared a
Turtle Art portfolio presentation of some Sugar project that they had
worked on previously. We explored the use of Turtle Art collaboration:
we created a solar system simulation where each planet was a turtle
shared from a separate laptop. (The children had been using Paint to
draw models of planetary orbits, hence it was an obvious example. We
discussed using Sugar to explore different representations and
consequently looked at the Abacus activity. I demonstrated how you
could represent the same number on different abacuses and in
discussion, we invented a new (to me) abacus, which lets you add and
subtract common fractions. (I implemented the "Caacupé" abacus in v15,
which I released today.)

A final story from Paraguay. Cecilia told me story of a young boy who
wanted to know what his sister was texting to her boy friend. He
couldn't read, so he transcribed the text to the Speak activity in
order to listen to her words.

That night I flew to Argentina. I spent Tuesday in Buenos Aires with
Kalil Nicholas, Claudia Urea, and Antonio Battro. Antonio was quite
taken with the Visual Match activity, which he appropriately renamed
"Dimensions". We met with the City of Buenos Aires ministry of
education, to whom I demonstrated Sugar. (One of the ministry
delegation had Sugar running in a virtual machine on his MacBook.) I
spent the afternoon watch Argentina play futbol will talking Sugar
with Gonzalo Odiard. Gonzalo and the rest of Sugar Labs Argentina have
been doing a great job of squashing bugs, enhancing activities, and,
as I was to find out later in the week, helping with the La Rioja
deployment. Gonzalo demoed Paint, which he had modified to take
advantage of the slide keys at the top of the XO keyboard: running
your finger along the slider changes the brush size. It was exactly
what I had imaged when we designed the membrane keyboard.

Tuesday night, I was in Montevideo; I stayed with Pablo Flores from
Ceibal Jam. Pablo live

My expectation was that the child user would use backup daily, or more
frequently, and a full restore only if a laptop was reimaged or all
content was lost.

I may not understand the design yet.

To lose all data sounds simple; child does backup of empty journal, child
fills journal with valuable content, child does restore.  Result empty
journal?

I think that could be solved by a merge restore.  This is just for
discussion, I'm not offering code or suggesting you defer your work just
for this.

Merge restore logic would be:

for each item in backup
if item is not in journal
attempt to restore it

Failure to proceed due to lack of disk space should be handled; by
advising the user that there is not enough available space to restore
the whole backup, and that only a portion of the backup was restored.

Being able to view the backup content in the journal would allow per
item restore.

I think regular backups are healthy and we should encourage kids to do
them.
NOTE: This is a backup to removable storage devices, not talking about the

Yes, it is a problem to loose _some_ data. But it is a bigger problem to
not being able to backup and restore, loosing _all_ data. For now this is
the state of the art :)

[Sugar-devel] [PATCH] Add cpu and memory resource indicator to frame

[anishmangal2002]

This patch adds an icon to the frame, whose palette
menu displays the memory and cpu resources. For computing
free memory, the code reads the /proc/meminfo file (thanks
quozl) and for computing cpu usage, the code reads the
/proc/stat file.

The palette menu entries are only updated (in one second
intervals) when the palette menu is visible thus
possibly saving cpu cycles.

A joke right? Something I missed from the early days? Any way, just incase not 
;-b – the occult and also Masonic all seeing eye seem a very dangerous choice, 
not to mention the warning hazard triangle icon (now I do just about remember 
the no 'triangles' episode) :-)

FWIW There are some simple school house type icons that could sugarise well, 
pretty much something like this very quick shape, perhaps making sure it's not 
too church like. There's other variations that can be flat top based, and/or 
place a round clock face in the top section and a couple of windows in the 
lower section. I could generate a few versions around this theme and see what 
works for folks?

What worries me with this is that it _destroys anything done since the
last backup_.

But the "full restore" case also has to handle low-disk-space. What do
you do when the data to restore does not fit in the disk? (For
example, because the user has downloaded & installed large
activities...)

Well, originally I added a XS backup and restore option (Journal
Management) into the Control Panel. Even when it was not intended for
upstreaming, I sent it to the mailing list, therefore a discussion started
about where these backup and restore options should go. Finally, this idea
of having the options in the resouces (volumes) palette was the most
wanted. 

The arguments favoring this idea were based on user friendliness: It seems
easier and makes more sense to find those options in the same context of
the resource that provides them.

Not yet, it does a full restore from the one that is available on the
storage device. For the Schoolserver backup, we plan to let users choose
from the list of available backups, in the future.

Yes, the entries added after the last backup will be lost.

At first sight it seemed easy to just append data, but there are many hard
to cover scenarios (Corner cases). Mostly the ones when you have to
consider the very few space available. So for the time being we don't merge
backups, still better than loosing all data :).

Re: [Sugar-devel] [PATCH] Journal Volumes Backup and Restore

[Martin Langhoff]

Hi Martin,

great to see action on this front. Thanks for working on this.

I have a few questions

 - Why is the UI in the main Journal UI? A manual backup should be a
very infrequent op. (And same with a "full" restore).

 - Is the 'restore' option a 'full restore' or does it allow to browse
existing backup snapshots?

...If it is a 'full restore', is it destructive? What does it do with
documents that already exist but have been modified locally? What does
it do with space concerns (ie: if the backup won't fit on disk) ?

cheers,


m

[Sugar-devel] [PATCH] Journal Volumes Backup and Restore

[Martin Abente]

Add a basic backup and restore feature for the Sugar Journal.
It provides:

- Generic Backup and Restore dialog GUI.
- Process manager class as an abstraction layer between the dialog and
  backup/restore scripts. (Allowing to work with many backup and restore
  technologies, using the same GUI, with no need for script rewrite).
- Basic file system Volume Restore and Backup scripts implemented in Python.
- New backup and restore options for journal volumes palettes.

This patch is based on Esteban Arias (Plan Ceibal) Volume Backup and Restore
patch, with a few changes:

- Refactor original Backup dialog class into a generic dialog class.
- Create specialized VolumeBackupDialog and VolumeRestoreDialog subclasses.
- Rewrite backup and restore scripts in python for an easier sugar interaction.
- Add backup identification helpers to jarabe.journal.misc.

There is no need in special treatment in Speak activity to pick up new
eSpeak languages, you need only update espeak in your distribution...
But I don't see any mentions in eSpeak sources about Haitian Creole,
better to ask eSpeak people on http://espeak.sourceforge.net/.

There were some design proposals from a time long ago and far away

[Sugar-devel] Schoolserver icon

[Bernie Innocenti]

Hello,

we don't seem to have an appropriate icon for the schoolserver in
sugar-artwork. What would you recommend?

We're using it in the contect of backup/restore to schoolserver, but in
the future it should probably be used in the network neighborhood to
access services provided by the schoolserver.

[Sugar-devel] sugar-shell

[Kevin Mauricio Benavides Castro]

hola a todos lo de la lista he observado que en algunas ocasiones, en
algunas XO cuando los niños habre una actividad no la carga y mas bien les
aparece en la parte de la vista hogar y en la parte de donde esta el diario
sale la actividad como que si estuviera iniciada, si coloco el puntero
justamente ahi me sale sugar-shell

en otras he observado que cuando intentas instalar la ultima version de
TortugArte v.88 da el mismo problema del mensaje de sugar-shell

esto es la primera vez que observo este error alguien ya le ha pasado antes.

Hi Guillermo,

can you tell us a bit more of background on why you are trying to
unregister? If it's for demo / testing, rm ~/.sugar and restarting
will work.

Step One is to post a ticket (bugs.sugarlabs.org) to request an
"enhancement". There is a "component" for Speak. Any background
material -- links to the specific modules you've identified would be
helpful.

I'm confused. Removing ~/.sugar will remove any record of the
registration on the Laptop. Is that not happening for you?

[Sugar-devel] Cleaning up XO like never was used

[Guillermo Narvaez]

Hi list!

once registered, the xo hide the 'register' option on the user menu,
now I need to leave it ready for use. Removing the ~/.sugar directory
is useful but i need that XO 'forget' it registration.

How can I do that?

You could not have picked better words to say to a teacher (though "here's a
million dollars" would also be nice), so thank you. :)

Yes, that's right (2.6), it's not a Windows/Linux thing.
If you're interested in teaching your brother Python 3.x, lowercase() got
replaced with ascii_lowercase(), and "print something" now has to be
"print(something)". Python 2.6 supports both "print x" and "print(x)",
however I chose the former approach in my tutorial because it's a bit
simpler and I can postpone explaining functions a bit. I plan to show that
"print(x)" also works, but after the lesson on functions.

Glad to hear it. Stick around - I'll be posting the rest of my lessons when
I get enough thumbs-up on this one.

Re: [Sugar-devel] Python tutorial for Pippy

[samir menon]

I have been looking for something like this for quite a while. I am going to
try to teach my little brother, (about 10) , to learn programming, and this
seems like the perfect way to do it. I have been learning python myself and
was very intriuged (sp?) by your code. However, when I went to run it, I
encountered a few problems: (BTW, I am on a windows machine, should I try
running it on my XO?)
-The function lowercase() ... is that in an older version of python?
-I am on python 3.1, was this written in 2.6 or something?

Other than that (by looking at your code) I see that this is an awesome
program! [?]

Re: [Sugar-devel] Keep error Write 60

[Martin Langhoff]

Hi David,

I agree on your concern about the bug. Very important.

One thing to note however is that the 'keep' button is very different
from a 'save' button in conventional software.

- Sugar activities save automatically (frequently, and then when you close it).

- The 'keep' button is to "save as a different document" --
potentially with a different name. (see the recent discussion about
it)

In short, what I am saying is that the bug you are hitting might be
slightly different from what you expect,

Re: [Sugar-devel] [GSoC] [Patch] Sugar Smolt Control Panel Integration

[Sascha Silbe]

Excerpts from Sebastian Dziallas's message of Sun Jun 27 21:07:11 +0200 2010:

> I've been working on an integration of Smolt
> (https://fedorahosted.org/smolt/) into Sugar as part of my GSoC. The
Nice!

> The repository lives here
> (http://git.sugarlabs.org/projects/sugar/repos/sugar-smolt) and
A quick look doesn't show any major mistakes (take that as praise ;) ).
There are a few minor style issues; pylint + pep8 might catch some of
the easy ones (like EOL spaces and naming conventions for constants).

Some questions I had:
- Why do you recommend to delete the profile (including UUID) after
  submission? Isn't one of the purposes of smolt support to be able
  to help individual users with hardware trouble (which would require
  knowing the UUID of the user)?
- Is the privacy policy really large enough that we need to destroy the
  widget even while the section view is active? (If section views are
  kept in memory even after they got closed, that should be fixed rather
  than worked around).

Suggestions:
- Only show the section if smolt is actually installed (not all distros
  have it). Might need support on the Sugar side as this check is
  currently hardcoded for the keyboard and power sections. The latter
  one even checks for /ofw, but that's stuff for the OHM support thread,
  not this one.
- Don't store the handler ids of the GTK callbacks if you don't use them.
  We don't need to keep a reference in our code to protect them from
  garbage collection.
- Maybe deactivate the Delete button if no profile is present? (Submitting
  a second time can be useful so that button should always be active).
- Assuming smoltSendProfile is synchronous (i.e. doesn't finish until
  sending the profile has either been finished successfully or failed),
  you should run it in the background. The Sugar shell is currently a
  single process, so running synchronously will block everything.
- Check for smolt errors (rc, stderr) and relay them to the user.


> I marked the ticket as r?, so a review would be appreciated, too.
Sending the patch to the mailing list makes it easier to review, so you'll
get more feedback that way.
My config is rather complicated because of the email address scheme I use,
but maybe it shows you how to automate everything so sending the patch to
the ML is as simple as typing a single git command. For patches that might
need to be revised before they can be committed I use TopGit.
"git rebase -i" is nice as well, but only works if you don't publish your
repository.

This is my ~/.gitconfig :

[user]
email = sascha-...@silbe.org
name = Sascha Silbe
[url "gitori...@git.sugarlabs.org:"]
pushInsteadOf = git://git.sugarlabs.org/
[alias]
send-to-ml-multi = "!git send-email -s --annotate --summary 
--cover-letter --add-header=\"Reply-To: Sascha Silbe 
\""
send-to-ml-single = "!git send-email -s -p --stat 
--add-header=\"Reply-To: Sascha Silbe \""
tg-send-to-ml-single = "!tg mail -s \"-p --stat 
--add-header=\\\"Reply-To: Sascha Silbe \\\"\""
[sendemail]
from = Sascha Silbe 
chainreplyto = false
signedoffcc = false
suppressfrom = true
confirm = always
[color]
diff = auto

And this is (part of) my .git/config for sugar:

Errors when saving should never happen, can you file a bug with logs attached?
