Why 0.88? F12 is supposed to ship both Sugar 0.86 and Gnash 0.8.6 (or 9 or whatever they call the next version). I think now is a good moment to test Gnash-based activities on Strawberry with the Gnash rpms I posted in the blog. Then, when Sugar 0.86 ships, all distros with an updated Gnash will be able to run these activities without any fuss. Hmmm, I guess that's actually more a distro question Yeah, it's a distro question, but the upstream roadmaps seem to be aligned so that distros can pick up this work in their next releases. Regards, Tomeu , if say a future SoaS or OLPC release decided to install custom gnash rpms, out side of the official Fedora release, then we could have support for your widget in a build with Sugar 0.86 (or even existing 0.84 using your set of rpms if it was considered essential for some specific content set). *** by push I mean creating/porting some Flash Activities (other than demonstrators - BTW if the eatboom swf really can't be fixed, I'd be happy to re-code the game from scratch, would only take me a day or so at most, that would be a fallback position if you just wanted a known working Flash sample for other developers).

Re: [Sugar-devel] help about the get_preview function of activity.Activity class to take screenshots
Hi Sumit,
I just fixed the example code in the pyabiword module of abiword to
give an example
of how this works.
The important line in this example is:
i.props.pixbuf = abi.render_page_to_image(1)
The converts page number 1 to a GdkPixbuf. Once you have a GdkPixbuf,
in this case in
a Gtk.Image you can convert it to whatever format you wish.
From the PyGtk reference manual http://www.pygtk.org/docs/pygtk/
you convert this to an image with:
http://www.pygtk.org/docs/pygtk/class-gdkpixbuf.html#method-gdkpixbuf--save
So if you wanted the GdkPixbuf directly you would do:
PagePixbuf = abi.render_page_to_image(1)
PagePixbuf.save(filename,png)
Where filename is the name of the file you wish to store to.
Cheers!
Martin
PS. here is test.py which shows the feature in action (thanks for the
patch tomeu!)

[Sugar-devel] Test the POSSE Education Fedora Remix today!
=== Test the POSSE Education Fedora Remix today! === Have you ever wanted to contribute - or get others to contribute - to an open source education project, but never found the time to set up and get started? We've got a ready-to-go contributors' (not just code!) environment for you. The Fedora Education SIG (http://fedoraproject.org/wiki/Education_SIG) announces today in cooperation with POSSE (http://teachingopensource.org/index.php/POSSE_2009), a Red Hat sponsored summer program to introduce professors to the open source way of development, the release of the POSSE Education remix. The remix will be deployed immediately to the professors at POSSE and has been developed with the purpose of creating a ready-to-go development environment for contributing to educational projects inside, but also outside of the Fedora ecosystem in mind. It contains development environments, tools, documentation, and getting-started resources for contributing to a number of projects including Fedora, Mozilla, Sugar Labs and KDE Education and can be used by individuals or by teachers, students, and classrooms that want to contribute to open source projects as part of their course effort. The download is directly available, together with the SHA-1 checksum, over HTTP from here: http://alt.fedoraproject.org/pub/alt/remixes/POSSE/POSSE-Education-1.iso 391a0170e09e68142cbe2c95b62b2b0c6fa628d5 POSSE-Education-1.iso Being based on the latest Fedora release, this remix provides users with a stable environment with supplemental features, such as: * an easy starting point into educational open source projects by providing pre-selected bookmarks and related IRC channels * the Sugar Platform (http://www.sugarlabs.org), as seen on the OLPC - as of 2009/07/15, all required dependencies for building sugar-jhbuild, a way of pulling and running the latest sugar bits, are included * a number of educational applications, such as the KDE Education Packages (http://edu.kde.org) or software for numerical operations - a Moodle session (http://www.moodle.org) to showcase an open source learning management system * a whole development environment including gcc, python and more, as well as Fedora's packaging tools - the Eclipse environment with plugins for Python and RPM, but also LaTeX and documentation purposes A getting started guide is also available and contains instructions for various applications and communities: https://fedorahosted.org/education/wiki/GetStarted If you are interested in getting in touch with the developers, other users or would just like to submit feedback, please join our mailing list here: http://www.redhat.com/mailman/listinfo/fedora-education-list. If you are interested in using this for your own development or in your classroom, or have an open source education project you'd like to see included in the next version, please let us know and we'll get you started.

The save/load functionality is ready and I'll be committing soon to elements. :-) Brian: What is the status of the library handling? I'll have to update elements after I commit to enable the new functions and commit BTW, the pickling function I added to elements was almost copy n' paste from the pybox2d testbed. I'm new to python but I think there is something that is not finished or maybe it wasn't cleaned up about the additional_vars in the pickle_load function. I'm not sure if that argument should be removed. When I'm doing my testing on your commits, I'll try and take a look and see. I also have other modification suggestions that I wanted to run by you before creating the tickets. 1. It IS possible to pin/link objects to the background (It just needs a 2 line hack). Should we enable this feature? By background, I'm assuming you mean the current solid ground. I tried to link some contraptions to the ground to act as foundations, though just pinning them to the background is a fine work around. Happy to see the feature enabled if it seems safe to you, it might enable some more possibilities if we add the option of different world environments (solid ground only, no ground, closed box), e.g. in a closed box environment kids might want to link objects hanging from the ceiling. 2. Modify the polygon tool icon. I suggest changing it for an irregular polygon. The icon gives the idea of a different behavior. Sure, seems like a good change (assign ticket to me if you want). 3. Modify the grab tool icon. Maybe put a hand shape. The current icon is not really descriptive. Sure, seems like a good change (assign ticket to me if you want). 4. Make the Play/Stop button more conspicuous, maybe change its color(s). Not so hot on this one :-) It breaks the Sugar design guidelines (colour represents user identity). Now I know Walter has quite seriously gone and broken these guidelines with some of his technicolor tool icons in TurtleArt... The shock, the horror... But not sure we should continue that slide in Sugar guideline standards ;-) Pro: Yes, black and white for Stop, and colour for Play is quite visually effective. Con: Once we start to creep into colour tool icons they'll start appearing all over the place and the collaboration colour == identity metaphor will start to break down. The high contrast silhouette of icon shapes is a strong component and differentiator of the Sugar UI design. The current 'Play' and 'Stop' icons are from the standard Sugar artwork set, perhaps we should just improve them. I was never completely keen on both their silhouette shapes being round, or perhaps it would be enough for the fill/stroke to be inverted between stop play shapes? Eben: maybe there is some design middle ground for having some tool icon colour in the HIG? Perhaps with a strict specification, say like a single colour (different brightness allowed) may be used in addition to white transparent, but only for toggle or radio buttons to indicate important active vs inactive states? But I'm not convinced. It feels like an erosion of a strong design principle.

[Sugar-devel] Correct use of leading underscores in Python?
I don't want to start a religious war here, but I could use some guidance. In writing my Activities I have often copied and pasted bits of code from other Activities. For instance, the toolbars from Read and Speak. As a result of this I have code in which leading underscores are used in both variable names and method names, with no particular rhyme or reason for it. I want my code to follow good practices, but the only thing I've found which talks about leading underscores in Python is the PEP 8 style guide, which says: In addition, the following special forms using leading or trailing underscores are recognized (these can generally be combined with any case convention): - _single_leading_underscore: weak internal use indicator. E.g. from M import * does not import objects whose name starts with an underscore. and also Use one leading underscore only for non-public methods and instance variables. None of the leading underscores in my code seem to be for these reasons. So when do you use leading underscores to name something? Or do you ever use them?

E.g. __init__, __import__ or __file__. Never invent such names; only use them as documented.

Re: [Sugar-devel] help about the get_preview function of activity.Activity class to take screenshots
Martin and Tomeu,
Martin, thanx a lot for such a detailed answer. I have got what you want to
say. But the problem with me right now is that I think the get_preview
function is available only in the latest release of sugar 0.84 because I am
on 0.82, and my xo gives an error -- Activity module does not have an
attribute get_preview . Is it so that the function has been added after
0.82 ? If yes, then is there any way on 0.82 build to take screenshots
programatically.
There is one strange thing which I am encountering right now. Though the log
gives an error that get_preview function is not present but when I ran write
63.xo on the machine ( after replacing sugar.graphics.colorbutton with
gtk.colorButton in toolbar.py ) , closed it and then again tried to restart
the activity from the journal , I was able to see the following preview
which I am attaching with this mail, that was what was there on my activity
screen before I closed it.
Though I am not very much sure, but this should have happened because of the
save function in activity.Activity class , here is the link-
http://api.sugarlabs.org/sugar.activity.activity-pysrc.html , which calls
the get_preview function of sugar, which is a bit contradictory, if we
consider the result of the logs. Am I wrong in the way I am understanding
this? Kindly give your comments.

Hi Sumit,
I just fixed the example code in the pyabiword module of abiword to
give an example
of how this works.
The important line in this example is:
i.props.pixbuf = abi.render_page_to_image(1)
The converts page number 1 to a GdkPixbuf. Once you have a GdkPixbuf,
in this case in
a Gtk.Image you can convert it to whatever format you wish.
From the PyGtk reference manual http://www.pygtk.org/docs/pygtk/
you convert this to an image with:
http://www.pygtk.org/docs/pygtk/class-gdkpixbuf.html#method-gdkpixbuf--save
So if you wanted the GdkPixbuf directly you would do:
PagePixbuf = abi.render_page_to_image(1)
PagePixbuf.save(filename,png)
Where filename is the name of the file you wish to store to.
Cheers!
Martin
PS. here is test.py which shows the feature in action (thanks for the
patch tomeu!)

Hi everyone,
Can anyone please guide me about the proper use of the get_preview
function
of the activity.Activity class of sugar. I had a look at its api, it
seems
to be returning a dictionary sort of thing which is called as the png
image.
What I want to do is to save this image somewhere in the datastore and
show
this image later to the user in my activity. So, what I want to ask is to
how to load this information in the form of an image later on
programatically. Can we load it using the gtk.image widget and what is
the
right procedure to save this information.
Regards,
sumit

[Sugar-devel] need a better name for starting page of karma than MenuStage
what should we call menustage? it is a horrible name. it is just not descriptive: http://www.pustakalaya.org/external-content/static/epaath/MenuStage.html I don't want to call it the frame because that word already has a meaning w/in sugar. i also don't want to call it anything w/ a religious connotation since karma is named after Rabi _karma_charya and not for the religious concept. Words that come to mind are mandala -- which literally means circle in Nepali but sometimes has a religious connotation (ugh) dhoka -- this means gate in Nepali. I like dhoka but everyone outside of Nepal will mispell it I like mandala the best so far . . . -- Bryan W.

[Sugar-devel] amRe: [Cs-dev] Sugar on a Stick - and OLPCsound/Csound
Hello, Peter et al. - Your latest Csound5.10 patch finally made it out to updates-testing today, and I was able to install it on SoaS (Sugar 84) and test it out. Unfortunately it aborts with much the same (if not exactly) as before. Log: /usr/lib/python2.6/site-packages/sugar/util.py:25: DeprecationWarning: the sha module is deprecated; use the hashlib module instead import sha Traceback (most recent call last): File /usr/bin/sugar-activity, line 21, in module main.main() File /usr/lib/python2.6/site-packages/sugar/activity/main.py, line 105, in main module = __import__(module_name) File /home/liveuser/Activities/OurMusic.activity/ourmusic.py, line 42, in module import csndsugui File /home/liveuser/Activities/OurMusic.activity/csndsugui.py, line 36, in module import csnd File /usr/lib/python2.6/site-packages/csnd.py, line 7, in module import _csnd ImportError: /usr/lib/libcsnd.so.5.1: undefined symbol: csoundGetInputBuffer Observations: /usr/lib/ contains libcsound.so.5.1 and 5.2, but only libcsnd.so.5.1. (I've no idea if this is significant or not.) I note that Sugar 82 - designed for 5.08 - (at least on my OLPC) contains none of these files. TamTamMini plays fine on both 82 and 84; of course it only plays samples. TamTamSynthLab seems to work fine with 82 (no errors), but not in 84 - where the log shows a multitude of .so files incompatible with Csound5.10 (stated as 2.0 and 1.6??). And, following that, an even larger list of illegal opcodes and errors. If I were to guess something, it would be this: is perhaps libcsnd.so.5.2 required for Csound5.10? Needless to say, I'd sure like this to work. Thanks, as always, for any and all insights.

[Sugar-devel] Planning for Weds - Tux Paint, Conozco Uruguay, Memorize with Speak
Hi, I'm doing lesson planning for Weds, the 3rd graders. They are the ones who would test out these three activites. I want to check in on the current status I think it is: 1. Tux Paint - Waiting for it to save to the Journal before we let the kids use it 2. Conozco Uruguay - Waiting for a version that fits different sized screens 3. Memorize with Speak - crashes when you try to use Speak. thanks, Caroline -- Caroline Meeks Solution Grove carol...@solutiongrove.com 617-500-3488 - Office 505-213-3268 - Fax ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel
[Sugar-devel] activity.info hosts
Hi all, I was wondering whether there were any plans to make use of the hosts variable in the activity.info files to determine whether an activity runs on the specific Sugar installation. With 0.86 being on the horizont, 0.84 being used on SoaS, 0.82 being widely used among the G1G1 community and some deployments and many deployment still using pre-0.82 software I think the issue of activity compatibility deserves some serious attention. Otherwise this has the potential to create _a lot of_ confusion and frustration further down the road. Not sure what the original plans wrt the technical implemention of this feature were but I would assume the harder part of solving this problem is spreading the word among activity developers to update their .xo bundles accordingly.
