Re: [Sugar-devel] [Server-devel] Fwd: Regarding adding a moodle plugin
That would be a killer addon! I could just use libxmlrpc and write an activity which sends the pdfs to the php data warehouse server side, also prompt for the user's login. But wouldn't it be really the same thing as logging in from the moodle's plugin page, and sending those files?

Re: [Sugar-devel] [Server-devel] Fwd: Regarding adding a moodle plugin
Well, thought that your workflow was to 1 - use activity X to create / get the document to print 2 - hit a print button or option in the Journal - this creates a PDF 3 - go to Browse.xo and visit the Local schoolserver which shows the Moodle UI 4 - find the print page, and upload the PDF to it with an xmlrpm point of entry, we cut #3 and #4. And we can pass the appropriate credentials to moodle, avoiding it askingfor a username and password. Having the webbased upload files to print UI will be needed as a fallback for users (teachers or others in the schools) that use a non-XO / non-Sugar laptop and need to print. m On Wed, Mar 25, 2009 at 12:18 PM, Vamsi Krishna Davuluri vamsi.davul...@gmail.com wrote: That would be a killer addon!

- new Activities may include with the m the ability to turn their own document files into a PDF, so at activity-install time, you may want to poke the activity metadata to extend the list of mimetypes handled. - cups has lots of overhead and complication, if you find a simpler way to print to PDF, it will be a big win I have a fix for Write which exports to pdf, but to implement the lib abiword api in each and every activity is really a pain - more for the activity authors. Luke was kind enough to check an installation of complete cups on the XO. It took a space of 18 mb including cache space, so an installation of cups-pdf alone (which is 1.3 mb installation space along with dependencies will be around 8 mb)will do. What cups-pdf does is it has the ability to print a pdf from any mime type associated with cups mime.types. As opposed to what the abiword api does (draw the screen to graphic objects and export to pdf) . So this is really an asset! Of course, the activities would definitely have to have their mime types associated in some .info file, I will just look it up.

Re: [Sugar-devel] [IAEP] [Announce] Sugar Labs wiki team 2009 launch meeting 30 March 2009 17:00 UTC (13:00 EDT, 10:00 PDT)
The biggest gap in our wiki is scheduling and providing feedback on meetings and events. It must be: 1a. Easy for a team coordinator to scheudal a meeting. 1b. Easy for a participant to add items to the agenda. 2. Easy for a new participant to discover when meetings are held. 3.Easy to find and review meeting logs. I was not able to come up with a solution which satisfied all four conditions. In fact some of my attempts ended up satisfying none of them:) S Page had some good ideas on how to accomplish this. The second gap is keeping todo lists up to date. Todo lists are how Sugar Labs communications what it is working on and what needs work to new contributors. But, they are current a pain to keep up to date. david On Wed, Mar 25, 2009 at 1:53 AM, Frederick Grose fgr...@gmail.com wrote: Dave Farning has asked that we hold an irc chat meeting to organize a 2009 roadmap for the Sugar Labs wiki team.

Re: [Sugar-devel] GSoC idea: Chart/graph-making activity
The clipboard and the Journal are two recommended mechanisms. I would think that in the case of the Chart activity, the Journal would generally be more appropriate: you gather/generate some data in one activity, save to Journal, and then open the data file in Chart to explore various visualizations. Chart might export a PNG file to the Journal or clipboard, where it could be imported into Write or Turtle Art (Portfolio) for a report. Distance, which generates small, discrete chucks of data, exports directly to the clipboard. Of course, there are times when you would want to do the visualization as part of the data gathering process, a la Measure. Pipes we currently don't support. -walter On Wed, Mar 25, 2009 at 10:19 AM, Wade Brainerd wad...@gmail.com wrote: This whole thing brings to mind something that I've been curious about for awhile. What's the recommended way to transfer data between activities? Say, I record some data in Measure and want to import it into Chart.

IE, should we support specialize copy as text/csv (or whatever) and paste text/csv in our activities? Same goes for transferring of pictures. If I take a picture in Record and want to paint over it in Colors!, is Copy in Record and then Paste in Colors! the way to go, or should I have Colors! open the Record Journal entry?

Re: [Sugar-devel] [Bugs] #625 LOW: login screen on soas-2 should be branded?
I strongly support anything we can do to tell users what it is they are using, ideally with a version number. Can we envisage a sugarlabs splash page after the fedora splash page?

Hey Sean, FWIW I have successfully booted my XO-1 from SoaS-1 using an older image, I haven't tried the latest. I used LiveUSB Creator for Windows with a PATRIOT 2GB stick. What you might be seeing is that you have a SD card with a bootable partition on your XO. I think that might take priority over booting from USB. You can boot manually from OFW.. something like ok boot u:\boot\olpc.fth should locate 'boot\olpc.fth' on the USB key and start it manually. -Wade On Wed, Mar 25, 2009 at 10:58 AM, Sean DALY sdaly...@gmail.com wrote: I'm sorry, but I'm a bit confused here, is it possible or not at this time to boot an XO-1 from a SoaS image (as we claim on the wiki: http://wiki.sugarlabs.org/go/Sugar_on_a_Stick/Installation/OLPC)? if so, how? since the instructions for Option 1 on the wiki page are not working for me.

OK thanks Wade If you can tell me just which image you have, I can try with that one. Same behavior with the SD card in or out, and on the other XO with no SD card at all.

Re: [Sugar-devel] Summer of Code Proposal: Furthering Speech Recognition in Sugar.
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 satya komaragiri wrote: I can showcase one of its potential usages by integrating speech capabilities to the 'Listen and Spell' activity where the child can spell out the word verbally. I want to let the children speak out the spelling rather than type it out. As the alphabet of any language is limited (26 in the case of English, extension to any language would just mean getting a few people to read out the alphabet of that language). I think this is a very good idea. General speech recognition is error-prone and computationally intensive, but recognizing letter-names is a much easier problem. It also fits very well with our emphasis on young children who may still be learning to spell. I must admit that I cannot say exactly what this is useful for. In my experience, there is at most a very narrow age window in which children can spell, but not type. It would certainly be a very nifty demo, and might help us to engage users. Your proposal will have a better chance of being accepted if you can give a compelling use case example. Having a generic library will make system-wide integration easier by abstracting the interactions with the speech engine via DBUS etc. All the activities can use the speech capability as they see fit (spoken commands to control the activity is the most straightforward application that strikes me). My advice is to focus on letters, not commands. Letters are universal, and can be applied in any application that involves typing. Commands would have to be different for every activity, requiring endless new training data. (You could, however, include words like Control and Shift, which would allow users to access commands by speaking the shortcuts. Commands to Sugar itself, like Frame or Neighborhood view would also be appropriate.) I suggest you work in two stages: 1. Take an existing activity (perhaps Listen and Spell) and add the ability to do voice recognition of letters. This does not require any DBUS magic. In this way, you can show that your speech recognition is actually working (preferably on an XO, which can be provided to you). 2. Convert this into a system service that listens to the microphone and synthesizes keystrokes via XInput. (The effect, then, is just as if the letter had been typed on the keyboard.) Add a device to the Sugar frame to activate and deactivate this service. (This frame device might also have to mute the speakers, to avoid interference.) Note that, apart from the switch in the Sugar frame, this system would be applicable to any Linux (or even Linux-like) desktop. Extra credit: 3. Provide an interface for users to record a new set of voices for their own alphabet and language. - --Ben -BEGIN PGP SIGNATURE- Version: GnuPG v2.0.9 (GNU/Linux) iEYEARECAAYFAknKXGEACgkQUJT6e6HFtqTnPwCeOCa5PoFoNlpRdQ/lTl2x9CDn tY8AnjMCOXjWXZsSfHZwLGpMn32gVk/n =rbua -END PGP SIGNATURE- ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel

The range of choices available in the config file is huge, and I'm not sure what it really adds to give people a very limited UI. In the long term, I believe Sugar should have its own keyboard configuration system, based on libxkb (or maybe libxklavier), and enable whatever keyboard(s) that is/are chosen by the user during startup. I believe Martin has been working on a control-panel item to make this work, and I would be glad to help with this. Please help.

I suppose the one advantage is we won't be worse than GNOME if we just merge it as-is, but the code's off-the-cuff and the UI has been designed by me so I don't think we'll want to do that.

When I said it is going to be a pain I should've said it would be a sign of insanity :) to create our own X and console keyboard configuration system. wish there was something upstream to crib from at least.

This is better suited to the Keep as... (some other format) action. However, I do think that basic copy/paste within a given activity, or between activities, should be strongly encouraged. Sugar adds a visual, multi-item clipboard (with forthcoming previews/descriptions) in order to make even better suited to this task. It should never be _necessary_ to save something to the Journal in order to move data into another activity, for common image/text/media formats. Same goes for transferring of pictures.

[Sugar-devel] Fwd: Google Summer of Code proposal: Speech integration in sugar(Chirag Jain)
Hi Hemant, I am forwarding your mail to the new sugar devel list. It has been shifted to sugar-de...@lists.sugarlabs.org. Thanks for clarifying things. -- Forwarded message -- From: Hemant Goyal goyal.hem...@gmail.com Date: Wed, Mar 25, 2009 at 11:17 PM Subject: Re: Google Summer of Code proposal: Speech integration in sugar(Chirag Jain) To: chirag jain chiragjain1...@gmail.com Cc: g...@lists.laptop.org, Assim Deodia assim.deo...@gmail.com, Simon Schampijer si...@schampijer.de, Tomeu Vizoso to...@tomeuvizoso.net Hi Chirag, and others who might be interested in integrating speech synthesis into Sugar You can refer to some documents in http://google-summer-of-code-2008-olpc.googlecode.com/files/Hemant_Goyal.tar.gz to understand the current status of the Speech Synthesis integration project. Owing to my final year in engineering school,and other personal issues, that kept me busy I was unable to contribute to the project after GSOC. Here is a snapshot of the project for you: 1. I did write patches for the Configuration Module of Speech Synthesis, however, when I last checked, the Sugar Architecture had undergone some changes making my patches obsolete. You will have to rewrite those patches, however, most of logic will remain fixed. 2. You will have to understand the python-dotconf API that I wrote to modify the Configuration Files that Speech-dispatcher creates. The API has been used in the patches and they will serve as a ready reference for you to understand the python-dotconf API. The python-dotconf API project page can be found here : http://code.google.com/p/python-dotconf/ 3. You might have to undertake some Fedora packaging work to package the latest release of speech-dispatcher. For this you will need to have some elemantary knowledge of RPM package creation using SPEC files. The SPEC files are available in the GSOC project files that I mentioned before. 4. Essentially most of the ground work to integrate speech synthesis into Sugar/OLPC laptop is done. The work that is left to be done is to provide 2 frontend interfaces to the Speech Device [you can refer to the patches to understand what the Speech Device is] so that Speech Settings can be controlled through a GUI. 5. While I would not categorize the project as Advanced, I feel that you will certainly require skills with pyGTK to design the interfaces, and some skill to play with the Sugar Graphical User Interface - I am sure the lead sugar devs will certainly help you out on this. erikos, tomeu, and eben in the sugar community were very helpful. (erikos was my mentor btw) Feel free to ask me for more detailed technical designs. Last year the project scope became quite big for me to manage and complete within the timeframe of GSOC. You can leverage all the work that I have done and take this project to its success in 2 months.

Re: [Sugar-devel] GSoC idea: Chart/graph-making activity
I thought Fred was getting at a much simpler idea. For example, Measure, when it is collaborating, is sending a simple data stream to each member of the collaboration. Why couldn't a chart program join in and instead of rendering the datastream as a waveform, it would render it as a piechart. Of course, we'd need to consider that the chart program wouldn't be generating data, but if an activity which wants to share its data with other activities sticks to a simple streaming protocol, I don't think it is too difficult. -walter On Wed, Mar 25, 2009 at 5:21 PM, Benjamin M.

Ok - I'll take a look. As Martin points out, [writing our own X and console keyboard config system] is going to be a pain, since there is virtually no way (AFAIK) to manipulate/query xkb stuff using Python - but this feature needs to be added. When I said it is going to be a pain I should've said it would be a sign of insanity :) to create our own X and console keyboard configuration system. wish there was something upstream to crib from at least. Perhaps KDE has something? I was quite surprised to find absolutely nothing but rhpl's hardcoded list[1]. I'm trying to implement a very basic python module for handling XKB stuff. It is based on libxklavier[1], and can currently show the layouts available, as well as the variants for each layout. I will put this into Git as soon as I have figured out how to set the XKB configuration as well. libxklavier is Gobject based, but the standard PyGobject wrapping stuff (h2def, etc) did not work for me, so I decided to do a simplified module instead, which should take care of all our requirements for the time being.

Re: [Sugar-devel] XO-1 keyboard issues, partial setxkbmap workaround
I'm trying to implement a very basic python module for handling XKB stuff. It is based on libxklavier[1], and can currently show the layouts available, as well as the variants for each layout. I will put this into Git as soon as I have figured out how to set the XKB configuration as well. libxklavier is Gobject based, but the standard PyGobject wrapping stuff (h2def, etc) did not work for me, so I decided to do a simplified module instead, which should take care of all our requirements for the time being. Fedora has a package called system-config-keyboard which is written in python. Not sure if that can be of help to you.

Re: [Sugar-devel] GSoC idea: Chart/graph-making activity
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Walter Bender wrote: I thought Fred was getting at a much simpler idea. For example, Measure, when it is collaborating, is sending a simple data stream to each member of the collaboration. Why couldn't a chart program join in and instead of rendering the datastream as a waveform, it would render it as a piechart. Of course, we'd need to consider that the chart program wouldn't be generating data, but if an activity which wants to share its data with other activities sticks to a simple streaming protocol, I don't think it is too difficult. That's a nice idea, really. What I'm saying is: it's not difficult to build it once, but it's difficult to ensure reliability when there are 100 versions of Measure and 100 versions of Chart, and they've each gone through countless revisions of the datastream format. Sugar is designed to encourage forking, which makes this sort of compatibility very hard. In the early days of Sugar this sort of problem happened frequently with central components of the system, causing flag days where multiple components of the system had to be upgraded simultaneously in order to maintain functionality. Clearly we can't achieve flag day upgrades of Activities, given our distributed development model. I have long pushed, and am continuing to push, a model in which any two people collaborating are using the _exact same Activity_. That is, upon joining someone's shared activity, if I don't have that precise bundle already, my system will silently download it, launch it, and join. (Bitfrost exists precisely to make this procedure safe.) That way, an Activity author only has to ensure that her code is compatible with itself. - --Ben -BEGIN PGP SIGNATURE- Version: GnuPG v2.0.9 (GNU/Linux) iEYEARECAAYFAknKtnMACgkQUJT6e6HFtqT5RgCfUhjENDiOaR9IxqhEUGXpuQYh y4AAn2nbuz4+o8C8SGm2DycmyVwEpAig =XeHc -END PGP SIGNATURE- ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel

One thing that we should think about, to help motivate teacher participation, is how we can deliver the project applications on other platforms -- primarily Windows. I understand the controversy with regard to porting Sugar to Windows, but I think we'll get a LOT more interest and support from teachers if what they're working on is something they can use in their own classrooms which, at least for the teachers where I live, means on computers running Windows. Is there a reasonably easy way to ensure that math4 applications can run on both the real target environment and on Windows? Is there some subset of the Sugar APIs we can use to make this easy? Is being limited to that subset going to unacceptably constrain the math4 apps? Perhaps we can explore other options, like Sugar on a Linux VM that's relatively easy to distribute and install? I'm not sure what the options are, but I am sure that enabling the participating teachers to use the math4 apps with their own students will really help the project.
