Re: [Sugar-devel] Network version of Abecedarium: why and how
Hi Tom, Very good idea! Dont tested but yes it should works. The WebView already reference the home page using file://bundlepath/html/index.html. I dont see any reason it cant access local images on USB key. Of course, it require one USB key for each XO. Lionel.

Hi Gonzalo, Hmmm, interesting. Youre right its a good way to explore to reduce the package size. Plus, most of the times images are displayed in the game at maximum 70% of the real size.

Hi, Lionel Besides any other optimizations, for a really quick and remorseless fix, you can run your images through Trimage, http://trimage.org/ , which uses some lossless compression libraries and seems to work nicely with your png resources (see attachment for an admittedly too small sample of results from your files, with impossible recursion added for fun).

The patch works with the latest Pygobject 3.8.x but as well in the 3.4.x
series.
Actually, using GLib.MAXINT32 would work as well. I will ask on #python
what the correct/better one is.

Re: [Sugar-devel] GSoC Translation Server Proposal
Hey Aneesh, Thanks a for going through, I'll try to answer your questions and clarify a bit for anyone else who's interested. Comments / criticisms from others on the mailing list are very welcome! I do apologize for the length of my messages, I wanted to be as specific as possible. It would be good if you could add the expected time you'll require to complete each of these phases below. Also, leave a buffer of 3 days between phases for review + feedback + other additions. Okay, will do. I think I'll have to wait until I figure out exactly what will be required in order to make an informed analysis of the time, but I expect the server / translation backend components to occupy the first half of the allocated time, finishing up some time around the midterm assessments. The client API should be a much simpler process, and will hopefully take no longer than 2 weeks. Again, I'll refine this to be far more specific when some more decisions are finalized. ...snip... The first of these plug-ins would be using Apertium, the FOSS project already used by Sugar through the #meeting-es irc channel on freenode. Next, Bing Translate will likely be added, due to it being one of the major web translators that provides a free API key. Just FYI: Bing only provides free service for upto 2 million characters per month. ( https://datamarket.azure.com/dataset/1899a118-d202-492c-aa16-ba21c33c06cb) Yeah, and the cost for the next 2 million ($40 USD) is pretty prohibitive in my view. Still, 2 million characters per month is not terrible if it's being used by a relatively small distribution of XOs / students. I do agree though that if there is a more free service, it should take preference. How about Bablefish? They don't have an API, but there is nothing which prevents you from creating one. And it seems like 20 lines of python code to me. Assuming you're talking about babelfish.com since there appear to be a couple services named babelfish. I didn't notice anything in their terms of use that prohibited screen scraping, so this definitely may look like a service to look in to. I'm not at all familiar with the quality of the translations though. I'm also a little wary of the fact that there appears to be so little information on them as a service. It seems that for all intents and purposes, the site barely exists. There's also babelfish.de which looks somewhat promising, but prohibits using automated scripts to grab data without the owner's permission. Google Translate is another high priority service due to its quality, but will not be added initially because its API has no free tier for usage. Do their terms and condition state that we can't make more than n requests? I read some threads on SO where people mentioned that they used some PHP code to make post requests to the google translate server. I just want to know that will this be illegal or will it void some of their terms and conditions? Google deactivated their free Translate API a few years back, so there's no official way to get a free translation from the service any more. It is possible (and very easy) to screen scrape Google Translate, but it's explicitly prohibited by the terms of service. Going against that would look bad for Sugar Labs, especially considering that this would be a Google Summer of Code project. I personally am very much against the idea of going around any terms of service agreement, but if someone really wanted to, there's nothing stopping someone from developing a third-party plug-in for the server independently of this project. - How do the clients become aware of the server? Is it configured, or is there some kind of auto-detection? I'd say we setup a public domain and hardcode it in the code! I'm not sure I understand your intent here. By this, you mean having only one server globally? In my mind, that would undermine the goal of having a server in the first place. Sure, having a default server run by Sugar Labs (or whoever) would make things more convenient, but I don't think it should be the only service. Part of the idea of this project is to allow users to create their own servers customized to what they need to do. Obviously having every activity that uses the API to rediscover the translation server is far from ideal, and would result in a lot of duplication. I'm not sure here, perhaps discovery could somehow be tied into the jabber server the XO is connected to? - Is it reasonable to establish large servers with more resources to be used by XO users who may not have access to a server or the technical abilities to manage one? How would abuse be prevented? What abuse? By abuse, I mean someone taking advantage of the server to provide them with unlimited translations. This is essentially only problematic when the server operator uses non-free translation services that may be limited by number of characters or is rate-limited. You also obviously don't want malicious

I tried with one on gimp, but you can use imagemagick or similar to reprocess all the directory Look: [gonzalo@localhost abc]$ ls -l total 152 -rw-rw-r--. 1 gonzalo gonzalo 19228 abr 24 17:59 accountant2.jpg -rw-rw-r--. 1 gonzalo gonzalo 16029 abr 24 17:59 accountant3.jpg -rw-rw-r--. 1 gonzalo gonzalo 21789 abr 24 17:56 accountant.gif -rw-rw-r--. 1 gonzalo gonzalo 28391 abr 24 17:57 accountant.jpg -rw-r--r--. 1 gonzalo gonzalo 62549 dic 9 22:57 accountant.png (accountant2.jpg is with quality 70% and accountant3.jpg with 50%) I don't know about the audio, but maybe is possible improve there too.

One issue with this activity is that, due to number of contents (1500 images and sounds), its size is about 100Mo. We want to deploy the activity on our Nosy Komba deployment this year: 150 XO-1 and 50 XO-1.5. Because we’ve got other activities to deploy, we compute: - The free space on a XO-1 and XO-1.5 with Sugar 0.96 without any activity: 550 Mo for XO-1, 2645Mo for XO-1.5. - The size of all activities that we planned to install, see the spreadsheet [1]. Unfortunately 100 Mo is too big for the XO-1 with some other big activities (GCompris, Tuxmath, TurtleArt, Speak, …). So I choose to develop a new version named “Abecedarium Net” [2] without any content included, so with a size of only 6Mo. The idea is to deploy all contents on a school/web server instead of into the activity. A config file in the activity has to be set with the URL of the content, or it could be set from a dialog popup. The activity test the network regularly and display the status. Because Abecedarium is wrote in HTML5, deploying the web server just mean to copy the content of the full activity on the server. I’ve explained the full process in the activity description. I will test it myself on our School Server at Madagascar but do not hesitate in the meantime to test it and give me feedback. Best regards from France. Lionel.

[Sugar-devel] Prototype python - js IPC
Hello, I wrote a quick prototype for a possible python - js IPC. sugar-toolkit-gtk3 patch https://github.com/dnarvaez/sugar-toolkit-gtk3/commit/5ba4e19732b4eec688dd73be8408c0d8e6a91299 hello-world patch https://github.com/dnarvaez/hello-world/commit/d102639bd43a99904d431210028a1ede66237427 You need the latest sugar-build if you want to give it a try. Though having a look at the code would be useful as well, it's pretty simple. Some notes: * It is based on websockets. I should note that we need some kind of IPC in any case because in WebKit2 and in modern browsers in general, the process where javascript is running and the UI process are separate. * This is communicating with the activity. I think in an ideal world the javascript code would communicate directly with system services. Though we have a lot of code which runs inside Activity to implement telepathy-based collaboration and we would have to rewrite it in javascript or somehow expose it as a service on dbus, which is going to make things even more fragile then they are already (it would be return of sugar-presence-service, sort of). I tend to think communicating with the activity process is a good compromise for now. The only way to avoid proxying through another process and talk directly to telepathy would be to implement dbus bindings in a WebKit extension, which I think at the moment would be too much work. * I'm not too convinced about introducing a dependency on twisted (I haven't measured memory usage/startup time though). It should not be too hard to write a basic GSocket based websocket server, we can look at the gtk broadway code for inspiration. * I have not picked a secondary protocol yet, autobahn implements WAMP for example. It shouldn't be hard anyway and easy to change. * The websocket server should authenticate the clients. WAMP would make that easy. The python code would generate a token and pass it to the start() call. The token would then be used to authenticate clients. In general, I need help thinking through the security implications here, not an expert! * I'm not sure finding a free port by trial and error is fine. Maybe the shell should manage a pool of ports. * This is all private to Sugar-on-linux. It should be wrapped inside the javascript API. * I don't know much about websockets performance. If anyone does please speak up :) At least they support binary transfers which we will need for collab. -- Daniel Narvaez ___ Sugar-devel mailing list Sugar-devel@lists.sugarlabs.org http://lists.sugarlabs.org/listinfo/sugar-devel

About binary streams, there is very likely a way to do it efficiently. ArrayBuffers for example looks like they might be helpful.
