Re: Is it possible to disable sharing for an Activity?
I think that the addition of a new property in the activity.info file would be logical here. Make it an integer indicating the maximum number of supported participants. Unshared activities would report '1', activities like video chat (with technical limitations) or chess (with obvious player limits) might specify 2, and others could specify another cap based on resource requirements and/or a constant to indicate an unbounded number. If robust activity sharing is ever going to make it past the Sugar GUI barrier, adding sharing properties to a Sugar-specific config file will just create an issue that needs cleaning up later. Wouldn't it be better to add a function or argument to the sharing API, that an application can use to limit the number of participants sharing the application? The world and the kids would be better off with e.g. a GNU Chess/ XBoard that's able to share on any platform, rather than a Chess Activity that only shares under Sugar.

Is it possible to disable sharing for an Activity?
First, I want to praise whoever put together the Sugar packages for Fedora 10. After struggling with Xubuntu and with sugar-jhbuild on openSUSE I finally have a sugar test environment where everything seems to work! It was well worth wiping out my openSUSE install and starting over with a new distribution. I'll probably do the same to my Xubuntu box eventually. Second, now that I have this I want to perfect collaboration on my two Activities, Read Etexts and View Slides. Unfortunately, I am convinced that collaboration in View Slides that involves sending large Zip archives over the network is not and never will be practical. What I'm thinking about now is making the person sharing a slide show see only the image being viewed on the XO that has the full presentation. The master XO would page through the slides and those sharing would follow along. I'm not sure that's practical, either. While I'm figuring this out, what I'd really like to do is release a version of View Slides that has no collaboration at all. This would mean hiding the control on the Activity toolbar that supports collaboration. When I figure out something intelligent to do with collaboration I'll restore it. Is this possible, and how would I go about doing it? Thanks, James Simmons ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: Is it possible to disable sharing for an Activity?
I think this project often makes the perfect into the enemy of the good.

Re: Is it possible to disable sharing for an Activity?
I think that the addition of a new property in the activity.info file would be logical here. Make it an integer indicating the maximum number of supported participants. Unshared activities would report '1', activities like video chat (with technical limitations) or chess (with obvious player limits) might specify 2, and others could specify another cap based on resource requirements and/or a constant to indicate an unbounded number. That number could be used both to show/hide the sharing controls (in the activity or elsewhere) for that activity, and also help keep the participants list at a manageable size for the given activity. Limitations are natural, and activity specific; it's not reasonable to expect all collaborative activities to scale in the same way. Scott (CC'd) has already come up with some really nice proposals for adding VNC as an alternate colaboration mechanism for all activities. In my mind, this would work perfectly with the above scheme, whereby any activity that already has max_participants in it could be viewed in that manner. Scott, could you point to any materials you've already written up on the matter? Would you have time and/or desire to assist others who are interested in taking on such a feature? I'd love to see this happen, myself, and have given some preliminary thought to the UI already. - Eben 2009/2/2 Carol Farlow Lerche c...@msbit.com: I'm guessing someone has already suggested this on some list or other, but in my experience kids like to watch over each other's shoulder, and a default collaboration of everyone watches, one person types vnc would in my opinion be the 80 of a collaboration 80-20 rule.

Re: [Sugar-devel] Is it possible to disable sharing for an Activity?
Gary, I've used it for many years on machines much less powerful than the XO, often for an sshable net meeting with multiple participants, and I think you might need to do a few simple things to speed it up for yourself. (Remove fancy graphic backdrop, try for a smaller palette). These things are pretty congruent with the normal state of the desktop on the XO.

I don't see why any Activity should be excluded from such VNC sharing, regardless of max_participants. Of course not. I didn't mean to imply such a limitation; only that the VNC solution would be the /only/ option after some participants limit was reached. That is, you could either Join or Watch any shared activity, but the Join option would disappear once full...Watch would remain. It's possible we'd have an upper bound on the number of people who could watch as well, but I don't think that's an activity-specific parameter. Oh! That's beautiful. Let's do that. I don't mean to rain on the parade here, but am I the only one who finds VNC slow even on high spec equipment over a dedicated broadband connection? I do use it occasionally for remote support, so it does have its uses – but a handful of XOs in the same wireless spectrum? Ouch. From a technical stand point VNC is going to be almost always more memory hungry, more cpu hungry, and more bandwidth hungry than most activity collaborations, seems to be an overly hopeful collaboration method to fallback on. Happy to be proven wrong, and I guess it could be a Sugar feature not really intended for XOs.

Scott, could you point to any materials you've already written up on the matter? Would you have time and/or desire to assist others who are interested in taking on such a feature? I'd love to see this happen, myself, and have given some preliminary thought to the UI already. Chris Ball has actually started to implement this: http://cananian.livejournal.com/54002.html http://blog.printf.net/articles/2009/01/26/multi-pointer-remote-desktop Written up in http://cscott.net/Publications/OLPC/sugarcamp-collab.pdf (video at http://www.youtube.com/watch?v=_7Ei2fp4Iww ). --scott -- ( http://cscott.net/ ) ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Let's let the flowers bloom: I don't doubt that there are many ways to make *better* collaboration, on an activity-by-activity basis. But VNC is something that can be created as a common baseline. Let's start by doing that, and improve it on a case-by-case basis, instead of having *no collaboration* as our baseline. FWIW, I second Carol's comments: VNC works quite nicely on fast local networks, such as direction connections between XOs, and I've used it on clients as simple as a Palm Pilot and a Mac SE/30. Reducing graphic busy-ness and palette size helps a lot! Also: don't run xvncviewer remotely: VNC is network efficient, but the way its X client uses the network between it and the X server is definitely *not*! --scott -- ( http://cscott.net/ ) ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
