Chrome has at least one process for each tab. Safari is also a wreck, especially on Windows. Webkit may be faster (although... with which javascript engine? on what graphics hardware? with which bookmarks/awesomebar system?) but I don't think it's so obvious. Previous comparisons on the XO have been deeply flawed because Gecko was scaling up all fonts and images, while Webkit was not. The test I have done both on OS X and soas have shown webkit to be far superior in execution speed and still superior in memory usage for benchmarks. These weren't entirely relevant, so I will do another set of benchmarks that are more relevant to XO usage (with firefox 3.6). Here are my old results: http://dl.dropbox.com/u/317039/webkit%20vs%20gecko%20osx.txt http://dl.dropbox.com/u/317039/webkit%20vs%20gecko%20soas.txt http://dl.dropbox.com/u/317039/webkit%20vs%20gecko%20winxp.txt While gecko has superior extendability (XUL extensions), Browse isn't compatible with Firefox extensions, so anything would need to be rewritten anyway. Userscripts (Greasemonkey) serve most needs for now and if needed, an extension API akin to Mozilla's Jetpack or Chrome's extensions could be implemented. This sounds like an argument for staying with Gecko and adopting Greasemonkey and Jetpack. It's an argument for not really needing Gecko. Both could be implemented on Webkit. Second, webkit is being used by a lot of projects and has the backing of several companies. Gecko is far more widely deployed (~30% of all internet users). The arguments other people have given to me have to do with how many projects use it (maintained by many companies/communities). Furthermore, it is packaged more consistently across platforms/distributions. I'm not sure what this means, but it doesn't seem critical. Xulrunner tends to have many patches applied by distros. Webkit doesn't. Third, pywebkitgtk and hulahop have a similar API (and pywebkitgtk tries not to diverge unless necessary) and it should be possible to not depend too much on any one of them. A thin abstraction layer could be written on top to handle most differences and it should only rarely be needed to go beneath this abstraction. While this would most likely not result in a browser than can switch engines at runtime, it should make any future porting much easier. I'm certainly not going to complain about an abstraction layer of this sort. As I've said before, I think a lot of developers would enjoy an engine-agnostic browser widget. --Ben ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel While performance differences might be somewhat interesting, the fact that tests tend to be inconclusive suggests it is not a compelling reason to choose one over the other.

Is a webkit-based browser going to be easier to maintain in the near to long term? -walter -- Walter Bender Sugar Labs http://www.sugarlabs.org Yes, surely maintainability over the long term should be a major concern in making any decision. I think the fact that Mozilla might lose support for XPCOM ( if that's true) is something that matters.

Re: [Sugar-devel] Problem importing hulahop.webview() in sugar emulator
Hello Tomeu, Thank You once again for your guidance. Surely I will keep on posting the updates. I was also confused about the use of the statement- *hulahop.startup(os.path.join(env.get_profile_path(), 'gecko'))* * * What is the significance of hulahop.startup? It surely seems to be imp. since the absence of this line results into an error. Also, gecko folder seems to be containing paths to different xulrunner files. Does including the same gecko folder (as is used in sugar) into the socialcalc package which we will make for fedora, and referring to this folder through the hulahop.startup statement work on fedora as well?

Re: [Sugar-devel] Sugar-devel Digest, Vol 15, Issue 17
Hello Simon, I would support what Bert mentioned in one of his mails- *When selecting an activity icon it would show the most recent Journal entries and an icon to start a new instance. Fitt's law would suggest to either pop it up close to the activity item, or put it in a predictable place at the screen edge. The former would be almost trivial to implement - simply bring up the palette on click and have it fully expanded right away. The double-hovering is just too undiscoverable and time-consuming. Click-choose-click would be much faster.* * * * * -- Forwarded message -- From: Simon Schampijer si...@schampijer.de To: sugar-devel@lists.sugarlabs.org Date: Fri, 08 Jan 2010 08:31:29 +0100 Subject: Re: [Sugar-devel] [DESIGN] 'Resume' vs 'Start a new' Activity Hi Vijit, So, if I understand you correctly, 'start a new activity' should be the default behavior, when you left click on the activity icon - and this should be represented in the primary palette (top), too. Actually, there is a gconf option (/schemas/desktop/sugar/desktop/favorites_mode) that can be toggled to change the behavior, the layout of the palette is not changed though. Would be a good test to try it out. I think what Bert mentioned in his mail would be a good option and this is very close to what I wanted to say in my last mail. Any comment about the delay of the palette? I think removing the delay thing completely and showing the complete palette when the icon is clicked and let the user decide whether to start with a new activity or a previous version of the activity( by showing the journal entries of that activity) would be a much better option. However, from the coding point of view I am not sure about its feasibilty, I mean afaik the basic characterstic working of palette is like that only i.e. to display the whole palette only after a delay( when being hovered) and I couldn't find any function in the palette module to change this characterstic . So, it might just require a change in the palette module as well. Still I am not sure about this because I haven't dealt much with palette earlier and couldn't devote much time in searching for the correct way to do so.

Re: [Sugar-devel] [DESIGN] 'Resume' vs 'Start a new' Activity
Hello Simon, Yes, I believe that's a good point. It's a bit confusing at times. I myself got confused a few times in the beginning when I switched over from sugar 0.82 to 0.84 and was in a habit of clicking the activity icon at once as in sugar 0.82. I think a better option would be to - 1) show the start option for a fresh instance of the activity when someone hovers over the activity icon. 2) start a fresh instance when someone clicks left mouse button. 3) show the whole palette( including the previous instances) when someone clicks the right mouse button or waits after hovering. Regards, VIJIT I have observed certain difficulties with the 'resume' and 'start a new' activity concept. At the moment we have the following situation: *** Current Situation: In the Home View you can resume an activity and start a new one. The option to start a new activity is in the palette of the activity icon. A list of last entries from this activity type is present in the palette as well. When you click on the icon with the left mouse button, the last activity is resumed by default. Clicking with the right mouse button on the icon does reveal the activity palette. The activity is revealed after a delay when hovering over the icon, too. Since version 0.86 when you hold the alt-key pressed and click on the activity icon you can start a new activity. This is visually guided by the uncolored activity icon. In the Journal you can resume activities. There is no option to start a new activity from within the Journal. *** Background: I teach a Sugar class of 15 students (5th and 6th grade) in a German primary school [1]. The classes are on a weekly one hour basis. They had 10-15 hours of Sugar by now. We use Sugar 0.84 on Fedora 11. I explained the concept of the Journal, repeated several times how to start a new activity and how to resume one. I explained them that revealing of the palette is quicker when using the right mouse button. *** Disclaimer: The information below is not meant to be hard data. There are differences in backgrounds (cultural etc), ages and quite importantly: a difference between a first time user, a regular user and a daily user. Some might as well question if I have chosen the right methodical way to explain things, and be sure sometimes I do question myself, however the data gathered might be a good basis for discussing this issue and maybe others will provide some data, too. *** Observations: Most of the kids click on the activity icon when they want to start a new activity. Since there is a delay to reveal the palette, the learner does not see the other information in the palette. When they resume a previous activity, and they wanted to start a new one, I have seen learners erasing the previous content and keep on working in that activity. Nearly all the kids do not use the right click to reveal the palette. They wait for it to appear. *** Survey: Last class I asked the learners in a small survey the following questions: A: How do you do a new drawing in TurtleArt? R: Some: Nothing, or did misunderstood the question. Some: I click on TurtleArt. One said: One clicks with the right mouse on TurtleArt and clicks with the left one on New. One said: Go on TurtleArt, wait, click New. A: How do you edit a previous drawing in TurtleArt? R: Many: Go to the Journal and resume there. One: Go to Journal or right click and choose the one one want to resume. One: Go on TurtleArt and choose the name one wants to resume. Some: Nothing / did not understand the question A: Is there a difference between the right mouse click and the left mouse click? R: One: it is quicker to use the right mouse button. Some: you get a new field/list. Many: Nothing / did not understand the question *** Comments: The concept of using the Journal to resume a previous activity does work very well for the kids. With adding the list of previous activities to the activity palette in the home view we added that concept to the home view. The issue is, it is a secondary option. There is only one way in Sugar to start a new activity - to work from scratch. And this is a secondary option. For me it would be worth trying to test going back to create a new one by default, as I think this is what my learners somehow expected. Small additions to the activity palette could be helpful, too. Adding the journal date field to the entries. And having headers like in [2], though I think there was a technical issue with this. Another improvement could be to cut the delay, so the secondary options are more prominent. Or, the left mouse click would reveal the palette and the learner then needs to decide what option to choose. This would clash with the rest of the UI I guess. I remember we had some design mockups quite some time ago, where a certain amount of Journal entries where displayed in the home view in a horizontal time line. Maybe this would help to make
Re: [Sugar-devel] Error running socialcalc on sugar live cd
Hello Tomeu and all, I just got the chance to try installing socialcalc on the sugar live cd and I have been able to install it properly. Here is the review of the process, might be helpful for other activities also in case anybody faces a similar problem-- 1. Actually, the error which was coming earlier was because of the permission being denied by sugar. So, in order to install any activity one is supposed to use the sudo command to have super user access. I mean, the following command would lead to above mentioned errors--- sugar-install-bundle SocialCalcActivity.xo However, using sudo will resolve the issue-- sudo sugar-install-bundle SocialCalcActivity.xo 2. However, I was unable to install the activity directly from the journal, when we click on the activity bundle in the journal, nothing actually happens. Hi, can you check you can write to /home/olpc/Activities? Yes, we can write but by using sudo command.

Re: [Sugar-devel] Error running socialcalc on sugar live cd
Hello Walter and all, The directory /home/olpc/Activities should be writable by user olpc. Yes, they should be in the live cd also as they are writable in the normal xo and the sugar emulator as well. That would explain your trouble with installing activities. The question remains, why was the ownership/write permissions of /home/olpc/Activities improperly set? Well, I didn't changed any settings ( I think sugar doesn't permits an user or even an administrator to change such settings on the sugar system). So, I think these permissions are set by default in the live cd by the rainbow system. I think some more related person would be able to explain better. -walter Cheers, VIJIT ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel

Hi Tomeu, # /var/lib/python-support/python2.5/xpcom/xpt.py:72: RuntimeWarning: tp_compare didn't return -1 or -2 for exception I think this is due to some python C modules being compiled with a python version and others with a different version. I think this is a runtime warning and not an error, so the exception which is coming in the log is not because of this warning. Still I tried removing python2.4 and running only with python2.5 to ensure only one python version is throughout, if that is what you wanted to say. Still, the same problem occurs. I think the error is because it is unable to include xpt.py module, however this is very strange because on line no 16 at http://pastebin.be/20740 , xpt is imported properly, which means the libraries are connected properly, but when we again try to include it in line 24, it gives error. The only difference b/w line 16 and line 24 is that at the latter one it tries to include it from a folder not in the same location as the module while in the former one it was imported from the same folder.

Re: [Sugar-devel] Help required in localization of FoodForce2
Hi Tomeu, Thank You for your kind and quick reply. I am thinking of a small activity which can be easily localized and whose code can be easily understood. I will be writing a very small pyGTK activity from scratch or otherwise I will be localizing a simple activity like 'HelloWorld' which is a simple tutorial activity made by sugarlabs. I will soon mail the details about the same.

I have been recently trying to localize this project to Hindi, and have run into issues towards doing the same. I have followed the steps mentioned at the wiki pages, and I am not sure, where I could have gone wrong. Please find the details of the steps followed by me below- 1. Selected the strings from the project files, which I wanted to translate. Selected 5 of them. These were contained in 2 python modules. So, I included gettext in these 2 modules, and then wrapped the 5 strings in gettext. Please find the details as follows- from gettext import gettext as _ # at the top of both the modules _(‘string to be translated’)# with the 5 strings 2. Created a sub-directory namely po in the main FoodForceII directory. Then, I created POTFILES.in file in the po directory, and added- encoding: UTF-8 Foodforce2.py gui_buttons.py FoodForce2.py and gui_buttons.py are the modules, which contain the strings to be translated. 3. Tried creating the .POT file for FoodForceII. Ran the olpc-setup.py file (the setup file for FoodForce2) with genpot command. Received the following error message- Xgettext error: Can’t include the svgsprite.py file: no such file exist svgsprite.py is a module required for running pygames in the sugar environment. Encountered similar error with every file in the olpcgames folder placed in the activity bundle. I experimented with moving the olpcgames folder outside the FoodForceII bundle, and then ran olpc-setup.py file with genpot. The FoodForce2.pot file was created in the po folder. 4. Now, I copied back the olpcgames folder into the FoodForce2 main directory .Now, we were supposed to generate a .po file. As, I was firstly translating the game into hindi language ( a regional language of INDIA); I gave the following command from inside the po folder in terminal- msginit -l hi hi becoz we were generating po file for the hindi language. It was successfully done and the hi.po file was created. So, now our po folder contains the following three files- FoodForce2.pot hi.po POTFILES.in 5. Now, the next step was to add the hindi text in the msgstr part in the hi.po file . As I am proficient in the hindi language I did the translation on my own using a hindi editor. The translated strings were placed between the quotes in the hi.po file for the 5 strings- msgstr “ “ 6. So, the next and final step was to make the .mo file. Firstly I created the following directories- locale/hi/LC_MESSAGES where the locale sub-directory was located directly in the FoodForce2 directory and hi was contained in locale sub-directory and LC_MESSAGES in hi sub-directory. Now, I ran the following command from inside the po folder in the terminal- msgfmt hi.po --output='../locale/hi/LC_MESSAGES/ org.laptop.FoodForce2.mo' And so the org.laptop.FoodForce2.mo file was generated in locale/hi/LC_MESSAGES 7. As all the necessary steps were done, I made a new xo bundle for FoodForce2 and then changed the language of my sugar environment to Hindi and then installed the bundle on it and ran the game. But, instead of the strings which I tried to translate appearing in HIndi, they appeared in english only. As these steps didn't result into a successful localization, I tried some other ways also but none gave the right result. The other changes which I made were- 1. As the i18n page I mentioned earlier in the mail was not very clear about this , so I included all the python modules present in FoodForce2 directory in the POTFILES.in and then generated the .pot file as done in step 2. I am still trying to work out why the translation is not taking place successfully. I would highly appreciate if anyone can send me some ideas about why it didn't it worked properly. I'm sorry but I don't have any concrete recommendations. What I would do in your place is to get a very simple activity written from scratch and make localization work there. After you got that, you could move to add localization to FoodForce with a more knowledge of what is required. It will be also easier to answer your questions about such a simple activity than about a big one like FoodForce. Hope it helps, Tomeu Regards, VIJIT SINGH
