I was exhausted that day.  Finally took some vacation time after that  
and
caught up on my sleep ;)  Anyway what do you say to a 7 year old that
  wants to help?  You do not say no, you say yes and encourage them.
  That is how to help develop inquisitiveness and volunteerism.

Thanks Tomeu to lead me to the /home/olpc/.local directory. However, the
mimetypes.xml is not necessary to get the icon in the journal. I just
had to copy the scratch icon file in the activity directory to
"application-x-scratch-project.svg" (also in the scratch activity
dirctory). The Memorize Activity is a good example for using that feature.
Sugar has to be restarted after installing Scratch to show the icon.

John, could you please make the following changes in the next Scratch
version:
- add the line "mime_types = application/x-scratch-project" to the
activity.info file
- copy the scratch icon to "application-x-scratch-project.svg" in the
activity directory

Etoys gets configured by different packages. e.g. the rpm
etoys-3.0.2153-1.noarch is adding the file
/usr/share/mime/packges/etoys.xml and the rpm 
sugar-artwork-0.82.3-1.olpc3 is
adding the file
/usr/share/icons/sugar/scalable/mimetypes/application-x-squake-project.svg.

The Flash Platform is the easiest way to do all of that. I haven't
seen anything that can tie up interactive media as easy with scalable
complexity like Flash has.

Some early pioneers were John Maeda, Joshua Davis, Yugo Nakamura,
Robert Hodgins, and Ze Frank. Back then, what you said was true, but
today you only need look at the growing army of Flash game developers
for starters.

You can go with Processing (http://www.processing.org/) but Java is a
bit problematic on the XO.

Why put yourself through unnecessary pain with the
HTML5/Javascript/CSS/SVG/whathaveyouforaudio&video&webcam combo? Add
to that the added headache of the standards fragmented browser
landscape. (whatever we develop for the XO re:OLPC goals, I hope we
can bring to other platforms as well.)

Why reinvent the wheel? Flash gets the job done, and gets it done easy.

For those who have a problem with proprietary technology, there's
always Gnash and SWFDec, and numerous open source tools to generate
SWFs (including some that come directly from Adobe like the free Flex
SDK).

Use the best tool for the job, pending personal comfort zones and
preferences. Get the job done, and get it done efficiently.

Peace out

-Naz

There's this:

rsync rsync://updates.laptop.org/build-767/root/

Not "web", and not "444", but useful all the same.

For instance, say you wanted to know what the file /etc/ntpdate looked

Re: Nand blaster with 30 XOs

[Ian Daniher]

Hi all,
.sugar is what needs to be removed to undo the name, color, etc.
After repairing and flashing an XO with os767.img, I boot the XO,
install the latest activities, and Ctrl-Alt-F1 to another terminal,
rm -r /home/olpc/.sugar, and send it off. ssh keys are not
automagically generated on first boot, last time I checked.

Something which would be nice to have is a publically accessible
webroot with a clean os767 build, chown -R'ed 444(read-only for all)

With advanced HTML you can imagine scalable interactive SVG maps, 
science texts with interactive JavaScript +  physics simulations 
(like the WIMS stuff but running in the browser), biology texts with 
layers that show and hide different anatomical systems... All with quiz 
modules that work offline and online.  Unfortunately collaborative

Sad to see some folks leaving: jobs available

[Gary Oberbrunner]

I'm sorry to see some familiar names gone from this list.  My G1G1 XO is
sad today.

But hopefully a brighter for those recently laid off: my company,
GenArts, is also hiring.  We make high-end special effects software for
movies and TV (www.genarts.com).  We are between Central and Harvard
squares on Mass Ave in Cambridge, which may be a draw for some folks on
this list.  We are looking for a QA/Release Engineer; a programmer with
GPGPU and image-processing experience; and an experienced web
application developer with Ruby and strong C++ coding skills.  Please
respond to j...@genarts.com, and if you'd like to forward this to folks
who may already be gone from the devel list, please feel free to do so.

What keeps me going...

[Sameer Verma]

So, a lot of people have been asking me this lately in the OLPC
context. "What keeps you going?" Of course, this question has been
asked by different people with different intentions. Some are
genuinely surprised that I have so much free time, while others
suspect a hidden treasure. So, I decided to shoot off this e-mail to
the lists for two reasons. One, I am not sure which list is
appropriate, and two, I think many of us do question the merits of
this project from time to time, and I want to share my sentiments with
you all. Feel free to delete if you don't like it.

During my visit to India a long time friend asked me this question.
"What keeps you going with a project like this?" He wanted to know
where I got all this free time from. Well, the assumption is a bit
off. A lot of the time I put into the project aligns with my
profession as well. Sustainable IT, network infrastructure, software
development, collaboration, etc. are all parts of my research stream.
so is FOSS development, adoption and use. So, finding time isn't that
much of a stretch. Its a two way street. I am able to bring these
things into my classroom and into my research. Of course, without
support from my family, this would be extremely difficult. For
instance, when I am off, gallivanting in Jamaica and working on a
pilot there, my wife has to cover for me and she does so with a lot of
effort, but we think its all for a good cause. We hope some of this
will make a difference in the lives of communities there.

Others, such as some of my students, have asked me the same question
but with a little "wink wink" glint in their eye. They think there is
something ulterior or somehow I am getting paid or I am bucking the
system (wonder where they got that idea from). Getting across the
volunteer ethic is very hard. Either you get it or you don't. Of
course, volunteer-ism is driven by many things including ego, fame,
and little green laptops. It is also driven by a desire to make a
difference in the system. Sometimes the system doesn't want that
change, but we still push for it. But that's another e-mail.

Then there are some of us who have an addictive desire to take things
apart. You know who I'm taking about! Take apart and put back together
things that most people would leave untouched. People who subscribe to
Make magazine or own a soldering iron would know. Its a strange itch,
but its an ethic that brings people together. Its hard to explain
these things to people who've never opened a radio, or a watch. On the
other hand, if you are the "Maker" type, you would instantly know. We
were surprised at the courage of attendees at the December OLPC-SF
meeting. They took their XOs apart and put them back together. Well,
most of us did. Only Robert needed some help from a 7 year old
attendee :-) (Sorry Robert. Couldn't resist!)

I think its a lot of these reasons that keep us all together in this
project and its offshoots, but one experience has captured my
enthusiasm unlike any other. This was a trip to Khairat, India's first
pilot site (http://wiki.laptop.org/go/Khairat_school). I had seen
pictures, and even videos and news clips of Khairat. But driving out
there with the folks from Reliance (the pilot partner) was a turning
point. Seeing five year olds handling their XOs with ease was just
amazing. Seeing them document their lives and showing me photos via
the journal suddenly made a lot of sense. All discussions of a lack of
a file manager were moot at that point. Rahul and Manisha sure don't
need a file manager to show me what they did! They could care less
about /etc or /usr/local/  I wish I could get the journal on my Ubuntu

They had documented a tight rope walker who visited Khairat. They had
documented Gandhi's birthday (2nd Oct) and showed me the photos. They
didn't care that Sugar was slow. After all, for them to know that
Sugar is slow, they would have to know something faster! They love
their XOs and it shows. Then there is Mr. Surve, the teacher at
Khairat. With very little training, this man gets his gang going. He's
built solar system animations in e-toys and precipitation cycle in
Paint. He has made his own lesson plans in Write and is constantly
yelling in Marathi (local language) "Go to the neighborhood. Join the
mesh". Who woulda thunk it? In the middle-of-nowhere-Khairat, a
teacher is yelling a his kids to join the mesh. A draft version of
802.11s has made it that far! Of course Rahul and Manisha don't know
that. And they don't need to, because we have a team of do-gooders who
take care of all that. And that's where my respect and unconditional
support for this group comes from. I've met very few of you in person.
But, my sentiments for this group as a whole are always equated with
the joy that is now in the lives of kids like Rahul and Manisha.

an offshoot of what OLPC has done, still fail to address key issues.

True. I was so anxious to use the method that I didn't pay much
attention to that.
But If we don't boot the XO  before the copying we'll lost the
opportunity to add some stuff.
If erikg has such a list, and we can revert some things, that would be awesome!

But hopefully a brighter for those recently laid off: my company, 
GenArts, is also hiring.  We make high-end special effects software for 
movies and TV (www.genarts.com).  We are between Central and Harvard 
squares on Mass Ave in Cambridge, which may be a draw for some folks on 
this list.  We are looking for a QA/Release Engineer; a programmer with

Coolness! Can someone wikify all these software solutions discussed in
the thread?
We should make a resource list of all these things.

I'd like to, but I'm catching up with a lot of work backlog and am not
very good with editing wikis yet.

if you've booted the XO, there's more than that that's been

Nand blaster with 30 XOs

[Ricardo Carrano]

Mitch,

Nandblaster is a blast! We updated 29 XOs in less than 30 minutes
(most in less than 20 minutes).
Just one XO froze (two times), but this unit seems problematic anyway.
I am attaching the stats for the other 28.

There is a minor caveat (that is not actually related to the
nandblaster): Once you finish updating the XO that will be replicated
it woud be useful to put it in a state such that the XO-name and color
will be asked again after boot (otherwise you finsh with a lot of xos
with the same name and color). It is probably a matter of removing a
file.

QA talk with Ed postponed to 15:30EST (42 minutes from now)

[Mel Chua]

This just in: http://wiki.laptop.org/go/XOCamp_2#QA is slated for 42 
minutes from now, at 3:30pm EST. It will be <45 minutes; the double 
whammy of "keep meetings on track" skillz of Ed and Mel will make sure 
of that. ;)

Please join us! #olpc, agenda at the link above; add questions, etc. - 
and we could *really* use a volunteer to be the IRC-to-1cc link, if 
you're interested (best: if you're not intensely interested in the 
discussion but want to be of great help in a few minutes - that way you

XOCamp 2, Day 1 update

[Samuel Klein]

Dear all,

We're in the middle of day 1 of XOCamp.  You can take part in a few ways; we are
 * streaming over the web at justin.tv  (search for xocamp and olpc),
 * on an call-in conference line (see the wiki page for details)
 * on IRC in the  #olpc channel on freenode.net.

For those without irc clients, you can use your browser: visit
http://forum.laptop.org/chat
to open #olpc-help, then type  "/join #olpc"

For the current week's agenda, and slides for many talks, please see:
http://wiki.laptop.org/go/XOCamp_2

We have a few sessions of open hacking, and are glad to include new
brief sessions or discussion topics; we can also present slides for
you if you can't do it in person / want to engage remotely.

Finally, we are archiving the conference media and transcripts; if you
have general questions about OLPC, our communities and deployments,
getting involved, or Sugar and hardware development, feel free to ask
them on the event's talk page and we will make sure your questions get
answered.

Guess I'm confused then - I thought that's exactly what Philipp had  
done.

And I just checked and it does work with Etoys projects. When  
downloading one it indeed gets an etoys icon (although at a smaller

 We are using the xdg mime database, the mimetypes.xml file contained
 in activities is added to that database. So that's the mechanism
 through which activities can associate icons to mime types.

Not sure about what we can do regarding this while not having to cook
our own mime info stuff. This is the spec implemented by the tools we
are using:

What does this merge do with conflicts?  It seems we might need a way
for the most recent activity which has used a given object to apply
its own icon for it, which isn't covered by this case.  Would the most
recently installed activity trump the rest?

Shipping a mimetypes.xml file inside the bundle as explained here:

http://wiki.laptop.org/go/Activity_bundles#Bundle_Structure

Sugar will call update-mime-database and will merge that file into the
xdg mime database.

I think that John is already trying this.

So what would the Scratch activity have to do so files put into the  
Journal (maybe by downloading) are displayed using a Scratch icon  
rather than the generic document icon?

We are using the xdg mime database, the mimetypes.xml file contained
in activities is added to that database. So that's the mechanism
through which activities can associate icons to mime types.

In a python shell inside strace -e open:

>>> gio.content_type_get_icon('image/png')
open("/home/tomeu/.local/share//mime/mime.cache", O_RDONLY|O_LARGEFILE) = 3
open("/home/tomeu/sugar-jhbuild/install/share/mime/mime.cache",
O_RDONLY|O_LARGEFILE) = 3
open("/usr/share/mime/mime.cache", O_RDONLY|O_LARGEFILE) = 3
open("/usr/local/share//mime/aliases", O_RDONLY|O_LARGEFILE) = -1
ENOENT (No such file or directory)
open("/usr/local/share//mime/subclasses", O_RDONLY|O_LARGEFILE) = -1
ENOENT (No such file or directory)
open("/usr/local/share//mime/icons", O_RDONLY|O_LARGEFILE) = -1 ENOENT
(No such file or directory)
open("/usr/local/share//mime/generic-icons", O_RDONLY|O_LARGEFILE) =
-1 ENOENT (No such file or directory)
open("/usr/share//mime/mime.cache", O_RDONLY|O_LARGEFILE) = 3
open("/usr/share/gdm//mime/aliases", O_RDONLY|O_LARGEFILE) = -1 ENOENT
(No such file or directory)
open("/usr/share/gdm//mime/subclasses", O_RDONLY|O_LARGEFILE) = -1
ENOENT (No such file or directory)

Maybe I misunderstood then. How is the icon for a mime type such as  
application/x-scratch-project found then?

Re: [Sugar-devel] Journal integration for Scratch

[Eben Eliason]

This is something I've briefly discussed with Marco in the past.  It
seems a natural extension of the idea of "objects" as first class
citizens of Sugar to allow those objects to have custom icons and
identities.  Right now, we have no such support.

The most natural way (at least for me, as a Mac user) to visualize
this idea is in the form of type/creator associations, by which an
object would be assigned the icon for type t as defined by its creator
c. This scheme is nice because it makes the effort on the part of
activities rather simple (most importantly, static): define your set
of icons and the mime-types the represent within your activity bundle,
and the system will always apply the correct icons.

However, it seems this can't work for Sugar.  I suppose we could
simply allow an activity to assign an icon to a given object at will,
as you mention.  It might be the best way to achieve a similar effect,
albeit with more effort on the part of activities.

Currently, only by changing the mime-type.

Is there a way to assign icons for files other than by saving it in an  
activity?

(Chris - your question is very good, timely and relevant, so CC'ing

There are 2 parts that may be localised...

  - The commandline tools - low priority, only exposed to the sysadmin
team that manages the deployment. They have to be unix/linux geeks
anyway...

  - The XS "UI": Moodle. This is what's worthwhile translating. We'll
use Moodle with a couple of customisations. The customisations are
still evolving but Moodle's strings are well established. The problem
is that it doesn't use Pootle, it uses its own translation strings
stuff. I've been discussing this... see

 It just has to be listed in the activity bundle's info file:

Ok, what you just did will tell Sugar that Scratch is able to open
files with the mime type 'application/x-scratch-project'. But this
will not affect the icon of those files.

Don't know myself :/

Well, activities are installed by a normal user so that file won't be
modified. Instead, the cache will live in ~/.local/share/mime

> Can I execute the mime db update on the command line?

Yes: update-mime-database ~/.local/share/mime

If you want to get the details and fully understand how this is done,
you can check this code:

http://git.sugarlabs.org/projects/sugar-toolkit/repos/mainline/blobs/master/src/sugar/bundle/activitybundle.py#line318

That gets executed when a bundle is unpacked and registered in the
shell. As you can see, if a file activity/mimetypes.xml is found in
the exploded dir, a symlink will be made to this file form the mime
dir and the updater script will be run.

HTH,

Thanks for the input, but I wasn't successful.

I tried the following:
1. Extracted the files of "Scratch-12.xo"
2. Added the line "mime_types = application/x-scratch-project" to the 
activity.info file
2. Created a new archive file "Scratch-12_mime.xo" with the change
3. Erased activity Scratch on the XO
4. Copied the file "Scratch-12_mime.xo" to the Journal
5. Started/Installed "Scratch-12_mime.xo"
6. Copied Scratch project to the Journal with "copy-to-journal test.sb 
-m 'application/x-scratch-project' -t test.sb"

test.sb still has the standard icon and not the Scratch cat icon in the 
Journal.

Which activity is using the mime db update feature? I would expect a new 
timestamp for the file /usr/share/mime/mime.cache after installing the 
activity.
Can I execute the mime db update on the command line?

Philipp
