OLPC as Project of the Day at FOSS.in
Hello, The CFP for FOSS.in 2008, one of the largest Free/Open Source Software conference in Asia, is out, and this time they are following a very different format, with the emphasis on _producing code_. The CFP is at http://foss.in/news/call-for-participation.html I'm thinking of proposing OLPC as a Project of the Day (or maybe a FOSS Workout - though I don't think much can be achieved in 3 hours). Possible talks that come to my mind (and on which I can talk with, some effort) include: a) Developing Sugar activities with GTK+ b) Hacking Sugar c) Collaboration in Sugar d) Developing Sugar Activities with PyGame Is anyone interested in presenting anything else on OLPC in FOSS.in ? Possible projects/workout sessions I'm willing to help coordinate include a Media (audio/video) viewer for Browse (similar to the PDF viewer I came up a few days back), a Translate sugar activity for on the fly translation of activities. Are there any projects/features which you can think of which can reach a demo-able state after one day of (possibly distributed) hacking ? If you cna think of them, do you think it will be possible for you to come to FOSS.in and help coordinate the hacking session ?

[9.1 Proposal] i18n and l10n: 9.1 and beyond
Hello, I would like to talk on some of the enhancements that some of us have been speaking about the i18n/l10n on the XO. The areas I would like to cover include: a) Input methods: Out current input system (XKB) is not enough for Chinese/Japanese/Korean, and even existing customers like Ethiopia have needs which are met with considerable difficulty with XKB. For 9.1, I propose that we switch to SCIM[1], which should take care of most (if not all) of our current requirements. b) Multiple, non English fallback languages: Many of our users will probably be multilingual. A Aymara speaker would like to see the UI strings falling back to Spanish translations in absence of Aymara instead of the normal, default English. We have the existing infrastructure in our core i18n infrastructure, implementing this is simply a matter of making changes in Sugar (and maybe Rainbow). c) Language packs: The current system of language packs is not very reliable (it overwrites the original translations in the system, installations cannot be easily undone, no versioning, etc). I want to switch to a RPM based language pack system for 9.1, which will be easier to deploy (especially if the customization key mechanism gets support for RPM). This will require support for multiple locale directories, and I'll talk about that as well (Ubuntu uses a similar approach - I plan to reuse their patches if possible). d) User modifiable translations: There has been a number of ideas on this - initially (during my last visit to 1CC), we were thinking of a Translate Activity which would let children add/modify translations, and optionally let them share the translations over the mesh. SJ and Scott have recently suggested a wiki-like editable UI, which would, definitely be much cooler ;-). I want to brainstorm on this, and try to figure out the amount of time we need to do this, the advantages, risks, tradeoffs, involved etc. I would also like feedback from the translation community on things which we can do to make your work easier. I will definitely bring these issues up in the talk/discussion that I have/ Thanks, Sayamindu -- Sayamindu Dasgupta [http://sayamindu.randomink.org/ramblings] ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Mostly this means supporting language packs which are installed in /home, not just ones installed in /, but I'd like to think about unifying the various bundles into a consistent format. Sounds like a valid plan - I see no major issues. My only concern is that the current language pack must go as soon as possible (which means 9.1 :-).

[Proposal] .xot bundles, for translations
Hello, One of the things in my TODO for 9.1 is to have a better mechanism for language packs[1] in the XO. The primary goal of language packs is to decouple the process of translations from the process of OS release as much as possible, since as our software gets larger and more complicated, it will become more and more difficult for translators to keep up with the pace of development. Our current language pack mechanism handles the decoupling part, but two of its significant shortcomings include a) Overwriting of existing translation files (it may overwrite the original .mo file in certain cases) b) Difficulty for deployments (deployments have to manual start each XO, and run the pack installer script from a console) c) No auto update mechanism I have been thinking of having a separate place in the filesystem for _new_ translations, and using RPM to manage the installation and upgradation of the new translations. However, Scott suggested in a recent email conversation that deploying new translations through a bundle like format (used for activities and content right now) may make more sense as users themselves can use the Sugar control panel to download updated translations (as currently done with activities). I think this may be a better option than RPMs as a) It makes the new translations user modifiable (we can have a translate activity later on which would let users modify the translations) b) It would be pretty trivial to add support for a new .xot format in the customization key mechanism (just unzip them in /home/olpc) However, this would need XO specific changes in glibc, python, etoys and scratch (I think). I already have patches for glibc and python (based on patches from Ubuntu, which already uses a similar system, where they generate language packs out of their launchpad/rosetta based translations) Am I missing something out here ? If there are no problems with this proposal, I would like to start testing such a system in Joyride (with at least glibc and python patched) by the end of the month.

A couple of additional notes from a private subthread... ...there are a few ways to use rpm/yum for unprivileged users (alternative DB, fakeroot, relocatable pkgs...), and I think we can use them for this. In fact, we could even build a simplistic rpm installer in python that handles a subset of what rpm does (hopefully this is not needed, it'd detract from the idea quite a bit) One valid criticism to using rpm - from a Sugar perspective - is that Sugar won't want to become tied to Fedora/RH. There's a case for thinking through if we can actually use rpm the way we want on Debian and/or apt on Fedora. Both rpm and apt are available in old/buggy versions in the other family of distros. Using rpm or apt Sugar would getting a bit further away from Windows (does cygwin carry either?) - a bit less so on OSX (where the fink toolchain will probably work alright, specially with translation pkgs, which are by definition noarch). Hmm, thinking about this a bit further, how about generating a tar.bz2 with the PO files, with a setup.py file, which can generate a .xot bundle (with MO files), as well as install in a specified location (same in function as the setup.py which comes with activities)? In that way, if someone decides to create a RPM for Fedora (assuming that Fedora goes the language pack way sometime in the future), or a Deb for Ubuntu (Ubuntu already uses a language pack system), they can do it easily (they would have write a spec file though).

Does that sound like a viable option ? I can still see some problems... You're working towards having these installable from a customization stick, right? On the customization stick, we would then want some way of differentiating language pack RPMs from other RPM packages - at least I don't think we want to give the ability to install RPMs in that fashion where we haven't before. I'm not sure how we can differentiate RPMs - can we use a different signing key, to sign the RPMs, for instance ? Also, do these RPMs write outside of /home? If so, you break the fast, incremental olpc-update method. Hmm - I do agree that this breaks upgrade. But one advantage of using RPMs is that you could push the following process to deployments: 1. install F11 on an x86 computer 2. run some simple commands to install livecd-creator and download our spec file 3. modify the spec file, adding in your language pack RPM 4. run a command to make a build and then they have their own *clean* build with their own language pack as a result. One disadvantage is that deployments (with secured laptops) that are not able to sign their own builds would be excluded..but this has always been the case. And I think the OLPC position at the moment is big deployments should sign their own builds; small deployments should have security disabled Might be worth a larger discussion with Chris and Ed. From what it seems (except for the advantages you have described) - it may make sense to use the older system of zip files (or have, even translation bundles) and install it under /home/olpc (that can be easily done, since the patch allows to specify the directory, instead of hardcoding it, as in Ubuntu). This will a) Make translations persist across updates b) Require minimal changes to the existing customization key mechanism c) Require minimal changes to the existing language pack building mechanism d) Let users modify/enhance the translations themselves, via a Sugar activity Of course, we would miss the bells and whistle that come with RPMs, but I think this is better than overwriting and moving around existing MO files (which is what we do now).

Re: FIltering out languages via kickstart
Hi, 2009/7/11 Alexander Boström a...@root.snowtree.se: I'm completely ignorant regarding how translations work even in plain Fedora and even more so for the OLPC systems, but pray tell, why can't these translations be shipped as regular Fedora updates? There are quite a few reasons. For example, our official, stable build (version 8.2.1) is based on Fedora 9 (which has been officially end-of-lifed recently), and runs Sugar 0.82, which has not seen any package upgrade in at least the 6 months (I'm not blaming the Sugar devs here, they are resource-starved, and need to prioritize accordingly). I don't see the official build changing before the last quarter of this year, and I know for sure, that at least one large scale pilot (1000 machines) is going to be deployed for the first time a certain region (translations for at least one of the languages to be enabled in that pilot did not exist a few months back). Doing new package releases is not feasible in this scenario. Even when we have an up to date system (eg F11 based), translation is usually typically done in many cases via a set of translation sprints at the very last moment. Submitting those translations upstream, then chasing down each and every package maintainer (upstream as well as distro) to do new releases within a very short timeframe is not something that is realistically possible. Hence the need for decoupling our translation process from the release and packaging process.

Thoughts? One of the main requirements of the features outlined in Scott's presentation (especially click2trans) is the ability to have translations which are editable by the non-root user. I think storing translations in $HOME addresses that. The ability to edit will definitely necessitate a Undo function, and the first step towards that would be store a copy of the original translation pack somewhere locally (version control is another possibility, but I would probably try to avoid more than what I can chew at the moment :-). Another very important aspect is to try to ensure the validity of individual messages as they get translated (eg: making sure that %s foo is translated as %s bar, and not simply as bar or %z bar). This validation can be done by libgettextpo, and I have been slowly working on python bindings for this (http://code.google.com/p/pygettextpo/). Regarding distribution of translations, apart from click2trans, we can also have an activity like Develop which would enable users to translate activities, as well as share translations and translation memories. In this regard, Google's recently announced translator toolkit might provide some inspirations :-) (http://googleblog.blogspot.com/2009/06/translating-worlds-information-with.html) Thanks, Sayamindu -- Sayamindu Dasgupta [http://sayamindu.randomink.org/ramblings] ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Does anyone know if there is a property of widgets that would control this

(examples of what we put here: important OLPC-specific packages which can't be included in Fedora, OLPC's fork of the unmaintained Sugar-0.84, the OLPC kernel) There are 3 repos: 1. f11 - RPMs to be available to both F11-for-XO1 and F11-for-1.5 builds 2. f11-xo1.5 - RPMs for the XO-1.5 build (not for XO-1) 3. f11-xo1 - RPMs for the XO-1 build (not for XO-1.5) Another possible use-case is to quickly test a new package before pushing it in Fedora's bodhi system which includes it in the official F-11 update stream (I use this method for large/tricky changes in olpc-utils) Thanks, Sayamindu -- Sayamindu Dasgupta [http://sayamindu.randomink.org/ramblings] ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Sugar with a virtual (onscreen) keyboard
[Apologies for the cross-posting] Hello, Thanks to the pointers provided by Peter Robinson, I got the Meego FVKBD (Free Virtual Keyboard)¹ running along with Sugar. A problem with the current FVKBD is that it supports only one base layout. Even variants of that layout (eg: CapsLock enabled, Symbols, etc) are treated as temporary, which means that you press the Caps key, enter a capital letter, and immediately after that, it gets reset back to the base layout (lower case qwerty). I wanted something which would be similar to the existing physical keyboards that we ship with the XO machines - with a dedicated key to switch between different scripts in the same keyboard. I had to extend the code of FVKBD to implement that, and with the modified FVKBD, I have spun a live-cd ISO (based on the current SOAS). You can download it from http://dev.laptop.org/~sayamindu/sugar-vkbd-test/sugar-vkbd-test.iso Apart from the modified FVKBD, I have added a default keyboard definition file which is for English + Bengali, and I've also included a sugar device-icon on the frame to control the appearance of the keyboard. I realize that more needs to be done to support non Latin scripts, and here are some of the issues I faced while converting the existing XKB Bengali layout: * Many scripts do not have a concept of upper case/lower case - so we need some other script specific way to divide the characters * In the current XKB configurations, non-symbol characters from other scripts are often placed in the position of what normally is symbols for QWERTY keyboards * Numerals pose an interesting problem, since in some places, native numerals/digits are quickly being obsoleted, and latin numerals (1,2,3..) are becoming the de-facto standard. In these cases, it may make sense to provide only _one_ layout/state for numerals, and allow users to input native numerals by hovering (touch + hold) on the virtual key for the latin digit. Among the general issues, I'm not sure how to deal with the keyboard taking up half of the screen real estate - it may be worthwhile to see if we can have a split screen sort of configuration while the keyboard is active. Thoughts, feedback, etc would be appreciated :-).

It didn't bother me too much, and this was in an 800x600 session, though ideally we would want the text insertion point to be visible above the keyboard (FWIW various iPad apps have different success in dealing with this, all of Apple's are fine, but it seems 3rd parties do need to do some work on the app side to keep this behaviour working at all times). Transparency is something which comes to mind. Another possibility might be to make the keyboard move up to the top half of the screen after a certain point - but that may be too annoying. Thoughts, feedback, etc would be appreciated :-). Yes, lot's of interesting items to cover :-) I'll try to start to put together a list. Some quick item that struck me right away: - the Meego keyboard design is clearly for casual typing/text entry, no way of typing commands or many symbols needed for basic programming work – diving into terminal to use vi, or worse emacs, is pretty much a dead end (unless ctrl and alt keys are hidden somewhere I couldn't find). Is it flexible enough to allow different activities to trigger different keyboards (or an extra row of custom keys)? Something like Pippy, or Terminal would need that kind of extra flexibility. Yes - it can be possible to load an extended layout (with for example, an extra panel on the top for extra characters). It may be a bit tricky, but sugar can probably provide an API to do this - and it would be easier if we can wrap libfvkbd in python or extend the library to use introspection. - z layering issues with frame, should it be over, under, part of? Currently it can be a mix depending on the sequence things are triggered. I suppose the frame should always come on top. I'm not sure how the window manager would deal with this - the window type of the keyboard panel is currently set to dock, which can be changed to a window, and that may work. - Ideally something (Gnome I assume?) should trigger the keyboard overlay when you focus on a text field, perhaps with some hints about what the 'return' key behaviour

I'm still trying to write a proof of concept implementation of this - it seems that there's no documentation anywhere for writing GTK+ modules :-( Yeah, I gave up and just used LD_PRELOAD when I had this problem.

I think for such cases, having a dbus service from sugar to show/hide the keyboard may be a good idea (at least some activities may be able to take advantage of it) You could add a gesture to force the keyboard up even for badly behaved applications.

Re: [Server-devel] Translating Moodle - a sustainable approach...?
Hi Martin, Apologies for the delayed response. On Mon, Sep 22, 2008 at 7:17 AM, Martin Langhoff [EMAIL PROTECTED] wrote: Hi Sayamindu, I am preparing a Moodle package for the XS and looking a bit into localisation strategies. Looks like Moodle and the XS software in general is going to be rather different from the laptop sw translation. For this release of the XS I am going to not worry too much about translations and focus -- it is a 'milestone' release, and I can coordinate with local teams how to install the localisation packages separately. For the next release (xs-0.6) I'd like to have a sustainable approach. In this email I will focus on Moodle, as a custom version of it will be the main UI of the XS. Mediawiki - another large app I am planning on packaging for the XS - has mostly the same issues around l10n/i18n. The Pootle approach - while good for Sugar apps, has several issues for the XS software: - gettext has technical and performance problems running in webservers -- part of the problem may have to do with how the PHP-gettext extension is written - however, this problem has been with us for a long time, and it is unlikely to be fixed in the short term. Moodle and Mediawiki both use custom systems for their strings. No successful PHP webapp I am aware of uses gettext :-/ - These custom systems have slightly different ways of handling string interpolation and plurals - Moodle has a large number of strings - ~10K (MW is smaller, I think) - Moodle has an active community in many languages, and an active translation team. Of course, not all translations have good coverage... - We will be customising Moodle extensively, so we'll want to override some strings, as well as add our own strings. It's also interesting to note that Moodle ships with its own strings editor to make it easy to maintain translations (and contribute them) :-) -- I guess it's what you have to do when you can't use pootle! So my thinking at the moment is as follows... - Get translators involved upstream, and contributing to the core translation. As part of this, make it easy for them to use a vanilla (unpatched) moodle, and give them some guidance as to what parts of moodle we actually use so that they can choose to focus if their time is (understandably) short. - Give translators access to a custom moodle that - shows the modified pages (with a some notes as to where to focus their attention) - grabs translation updates from upstream often (or can be told to fetch them 'now') - lets them edit the overrides All of this is naturally quite a bit of work to implement and to maintain over time. Moodle has a lot of surface (lots of UIs, pages, buttons, functionality) -- so this is a large task. However, I think it is valuable as it will be the face of the school server that users experience. (Of course, the XS has many other services for the XOs but most of them are transparent to the user.) One of the issues I see here is the relative difficulty in pushing translator upstream. I won't be a problem for active languages like Spanish, Turkish, etc, but for languages like Pashto, etc, which have very few people translating, are even lesser number of people with proper (if any) internet access, it is going to be a problem. However, as you say, it might be actually _worth_ the effort :-). On the other hand, Pootle actually handles a large number of project which are non-gettext based - in fact, we are the only large userbase of Pootle who use gettext and PO files. The other two large projects using Pootle are Mozilla and OpenOffice.org, which have their own i18n framework. I was wondering in that case, would it be possible for Moodle to publish/export translations files, which would essentially be a set of any kind of key-value pairs - even plain old CSV would do. If we can do that, I'm sure that we can come up with a workflow which would let people use Pootle to translate the custom version of Moodle for the XS. Do you think that makes sense ?

However, as you say, it might be actually _worth_ the effort :-). Well, we will need fairly good coverage of moodle in the translation. If we end up translating 70% of moodle strings to Pashto, it would make sense to share them upstream and try to get a Moodle Pashto thing going (with translators from the wider moodle community) so that the translation team is self-sustaining on the Moodle side. Agreed. In fact, I always try to be as upstream friendly as possible, so we can follow the Scratch translation methodology, where a tarball containing all the translations are generated and is integrated into upstream each week. Another concern is that there needs to be some manual checking before the files go into upstream. This is because some of the translators have problems comprehending how to translate strings like %s file and so on, mostly as a result of language barriers, and hence those must be checked before they cause issues upstream :) On the other hand, Pootle actually handles a large number of project which are non-gettext based - in fact, we are the only large userbase of Pootle who use gettext and PO files. Ah, ok. I didn't know that. We have to figure out a workflow that makes sense, I'll be happy to add glue wherever needed. I'll go through the translation files again by the end of this week to get a sense of what would work best for us. Do you think that makes sense ? Yes, we can export stuff from moodle, but I want to figure out a workflow. What translation team have we got that would be good to discuss workflows and involve a bit as early adopters?
