[sugar] Need guidance from a Pygtk guru
Hello,
I've learnt Python and Pygtk writing the Clock activity
(http://wiki.laptop.org/go/Clock_activity) and I'm now adding a new feature
to write the time in full letters to help children learn how to write and read
it. The clock has different display modes and the default one is to use a SVG
background. I encounter a strange behavior and I don't know where to look at
to correct it.
The display of the clock activity is composed of a gtk.VBox with a custom
ClockFace widget at the top, and a gtk.Label where I write the current time.
The user can decide to hide/show the written time with an icon in the
toolbar.
When the Label is not displayed, the XO has enough power to update the
ClockFace widget in less than 1 second, which is nice and what you would
expect from a clock with a hand for seconds.
But when the user selects to show the time and the code show() the gtk.Label,
the ClockFace widget takes more than 1 second to refresh. The whole activity
becomes unresponsive and it is even difficult to move the mouse to close it.
Gtk timer event every seconds can't follow up...
I've tracked the problem to these lines:
if radius != self._cache_radius:
f = open("clock.svg", "rb")
svg_data = f.read()
f.close()
loader = gtk.gdk.PixbufLoader("svg")
loader.set_size(int(2 * radius), int(2 * radius))
loader.write(svg_data)
loader.close()
self._cache_pixbuf = loader.get_pixbuf()
self._cache_radius = radius
pixbuf = self._cache_pixbuf # 1.1
ct = gtk.gdk.CairoContext(context)
t12=datetime.now() # PME
ct.set_source_pixbuf(pixbuf, x - radius, y - radius) # 1.2
t13=datetime.now() # PME
context.paint() # 1.3
t14=datetime.now()
print "PME %s 1.2->1.3=%ss 1.3->1.4=%ss" % (t14, t13-t12, t14-13)
context.stroke()
Without the gtk.Label displayed, a typical log trace is:
PME 2008-10-04 13:01:15.031723 +update_cb
PME 2008-10-04 13:01:15.033482 +draw
PME 2008-10-04 13:01:15.348868 1.2->1.3=0:00:00.231589s
1.3->1.4=0:00:00.083030s
PME 2008-10-04 13:01:15.354891 -draw
PME 2008-10-04 13:01:15.355902 -update_cb
The whole ClockFace update takes 0.32s.
ct.set_source_pixbuf call lasts 0.23s and context.paint one 0.08s.
Whenever the gtk.Label is shown, the pattern is totally different. Here is a
not so extreme log (I've kept only the significant lines):
PME 2008-10-04 10:48:42.025741 1.2->1.3=0:00:00.354320s
1.3->1.4=0:00:01.146650s
PME 2008-10-04 10:48:43.539496 1.2->1.3=0:00:00.307176s
1.3->1.4=0:00:01.196331s
PME 2008-10-04 10:48:45.074410 1.2->1.3=0:00:00.297737s
1.3->1.4=0:00:01.212910s
PME 2008-10-04 10:48:46.573627 1.2->1.3=0:00:00.311503s
1.3->1.4=0:00:01.176982s
PME 2008-10-04 10:48:48.091777 1.2->1.3=0:00:00.364210s
1.3->1.4=0:00:01.143602s
PME 2008-10-04 10:48:49.595859 1.2->1.3=0:00:00.342134s
1.3->1.4=0:00:01.151180s
PME 2008-10-04 10:48:51.082667 1.2->1.3=0:00:00.270270s
1.3->1.4=0:00:01.205943s
Now, ct.set_source_pixbuf call lasts 0.1s more and context.paint 1.1s. I've
even samples where the context.paint() call lasts 2.5 seconds!
As I've said, this strange behavior seems to occur only when the ClockFace
widget paints SVG. In the other display modes, the painting is drawn in the
code. I've seen it in 8.2-761 and still in candidate-767.
I've spent the last few days triying to find a reason for it, reading Gtk and
Pygtk docs, upgrading my XO to various releases and trying alternatives in
the code, without success. Has someone some ideas of what's happening and how
I could solve it?
Thanks

Re: [sugar] Narrative
Each of us seems to have interpreted Michael's note differently, so perhaps some more clarity of definitions is in order. In any case, my focus was on the assertion that there are "no excellent way to manipulate narratives" within Sugar. Excellence is the standard we should be striving for and I do agree we have a ways to go in terms of developing tools for "manipulating" "narratives" within Sugar. But it seems a funny dichotomy: manipulating narratives vs. modes for discovery. When I think about Sugar, I think about its providing a scaffolding for discovering, expressing, critiquing, and reflecting. Manipulating narrative seems to cut across all of these area (as does collaboration). We have a browser--the "discovery" platform du jour--but also an ebook reader and media player, and various tools for collecting and inspecting data (e.g, Measure and Distance). In terms of expression, we have a wide variety of tools, including word processing, rich media, programming, etc. Tools for critique and reflection seems the least developed thus far: we have chat and we have sharing and simple debugging tools, and we have the Journal, but we don't yet support (natively) much in the way of organizing data to make an analysis or argument. Is this the role Bryan expects Moodle to play? If so, I don't really see how. There are beginnings of tools such as spreadsheets, mindmaps, etc. being "Sugarized". What else should we add to this list? There is also a powerful presentation toolkit built into Etoys--is it the lack of PowerPoint that Bryan is missing?--but it is not very easy to find. Perhaps something more wiki-like or HTML-based would be better. Having it available off-line is probably as important as accessing an on-line system, such as is already available in Moodle and in general on any GNU/Linux (or even Windows) server. In terms of organizing school itself, Moodle and its like certainly have an important role to play. Sugar is not intended to be all things, but part of a learning ecosystem. There is certainly a paucity of lesson plans developed around Sugar: how does one best leverage this collection of tools for learning. And undoubtedly, a dearth of content readily packaged and categorized. But I don't see these as fundamental design flaws in Sugar as much as a place where more effort needs to be invested. Sugar is reaching a point of maturity where such investments make sense. In any case, I'd love to hear Michael's "interesting ideas". -walter ___ Sugar mailing list Sugar@lists.laptop.org http://lists.laptop.org/listinfo/sugar
[sugar] content bundle development
I made a content bundle with a single pdf following the instructions at http://wiki.laptop.org/go/Content_bundles. I then downloaded said bundle with the browser, went to the journal and resumed.

Re: [sugar] Sugar USB testing
CCing the Sugar list. It seems that one of the problems we will be encountering with generic spins is footprint. Even a standard Ubuntu without Sugar was seeming too fat to load from a LiveCD on a Pentium 4 with 256K of DRAM. Although we didn't try it, I expect Fedora would present similar challenges. I don't know how feasible it is to make a lean Fedora for these use cases: Maybe the subset of packages we grab for the OLPC image only. I defer to the magic that Dennis and Greg can yield. Meanwhile, it is probably worth looking at some of the purposefully small distros, such as TinyLinux, to see how bloated they get when we build Sugar on top of them.

You should only need an index.html file that points to your PDF.

Philippe, why not just distribute the pdf, as a pdf? What benefit is there in making a single pdf into Library bundle (unless you're just testing the process)? I must admit to not liking some of the old Library content, much of it Browse just copies into the Journal, then you have to resume the new pdf entry with Read, if you forget something is a pdf and have already viewed it, you end up with multiple copies in the Journal. Seems a bit backwards to me, I guess it makes the Library interface a zip archive utility for installing pdfs into the Journal. Apologies if you were just testing the bundle process. --Gary ___ Sugar mailing list Sugar@lists.laptop.org http://lists.laptop.org/listinfo/sugar

Re: [sugar] content bundle development
Thanks! That worked. But there are a few problems. I don't mind so much the extra clicks necessary to install the xol, but everytime I click on the bundle's name in the Browse activity, it _downloads_ the file. If the file is already on disk why the extra downloads? Next, the Reader activity does not automatically start after the download. I have to click on Open to do that. And if I click on OK, the download bar closes, and nothing happens. The natural thing to do seems to be to restart, i.e. click on the bundle's name again. All these downloads seem to remain in the journal taking up space until deleted. Last comment is that deleting the bundle in the Journal also deletes it from the XO, which is not exactly what I expected. Philippe -- The trouble with common sense is that it is so uncommon.

Re: [sugar] content bundle development
Given the annoying behaviour of the bundle that seems like a good idea. But I did like the idea of integrating the pdf with the browser library stuff. The idea was to distribute school manuals in pdf, each as a xol bundle and have the children download that. Before trying the procedure, I expected that once downloaded, the manuals would show up in the browser and clicking on a name would start the reader. No fuss.

Re: [sugar] content bundle development
There is a discussion thread about how to best handle PDF files here: http://lists.laptop.org/pipermail/library/2008-October/000847.html The problems you have identified are exactly the ones being discussed. There are three basic issues: "downloading" extra copies; the need to open through the Journal instead of directly; and the deletion question. Re extra copies, that is an artifact of not recognizing when file is already present. This problem should go away in the next iteration of the datastore. Re opening from the Journal, this is purposeful as part of a compromise we made in light of security concerns (See http://wiki.laptop.org/go/OLPC_Bitfrost#P_DOCUMENT:_file_store_service). However, we are working on taking first one and eventually two steps out of this process.

Is this the role Bryan expects Moodle to > play? I don't see a way for Sugar to natively support narratives or need to. I think that manipulating narratives is best done by html pages and specifically by Moodle. More effort needs to be invested in offline moodle to complement Sugar. The problem is that we really need a version of moodle that can easily run courses in an offline mode so that our kids can complete courses that bind together different kinds of material into a narrative. Offline moodle needs a lot of work to get working properly and really doesn't receive the attention it deserves. > If so, I don't really see how.
