Good that we're on the same wavelength - I had a similar thought! The annoying thing about Android, however, is that for an app to continue to work in the background it needs to be coded in that way. I suppose that if we were to treat Sugar as an 'appliance' UI (which is how I tend to think about it), this isn't such a bad idea.

I'll check with our education team and get back to you. This is a very valuable discussion to have! Some scenarios from our Education Manager: - When an activity freezes - When an activity stalls during loading - When an activity does something strange - e.g. sound doesn't work, journal entry doesn't load properly - During collaboration (this is a big one!). e.g. one person sees interactions but the other isn't able to - just never completely loads, or connection is never properly established, or it's just behaving unpredictably I think the goal should be to make Sugar more robust so that these scenarios don't happen.

I suppose that if we were to treat Sugar as an 'appliance' UI (which is how I tend to think about it), this isn't such a bad idea. An additional problem is startup time. Python code tends to be a lot slower to load and initialize than compiled Java bytecode. Anyway, closing an activity automatically when memory is short would still be preferable to the current behavior of trashing the VM until the OOM kicks in. A quick hack would be to limit the number of activities that can run simultaneously. I agree. How about 4? Seems sufficient for most productive workloads. It would exactly be that. A hack. How do we suppose to tell the children you can't run more than 4 activities at once? Our next OS will likely have the Dextrose resource monitor [1]. I don't think we should be expecting children to be managing their system resources, though. It should 'just work'. That was an attempt to make users more aware of the physical limits of the system rather than make the system itself smarter. +1 An unexpected consequence reported from Uruguay is that some children would open plenty of activities *intentionally* because it's fun to see the laptop cry! Well, I guess it means that the concepts of memory and CPU weren't too hard to grasp after all. Better not give them any pets, though. Its interesting. Uy dropped it. Py loves it. One change that does need to happen is replace the 'Cry [ :'( ]' icon with a 'Tired' one [ :'S ] .

(fwiw same as iOS), though the horse has already bolted due to the past calls to support GNOME ported applications with few design considerations for our resource targets. Perhaps we can release/exit activities that at least support the write_file() method, and maybe add an additional new method for something like remember_state(), seeing as the original design requirements were not strict enough in requiring developers to expect to completely resume state accurately (cursor position, UI view modes, etc). --Gary Do you have any other end-user use cases that have Ctrl-Alt-Erase as a solution? cheers, m -- martin.langh...@gmail.com mar...@laptop.org -- Software Architect - OLPC - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

I don't know if she got the idea because I suggested it to my gd or if it happened some other way. My gd has agreed to take notes about how the videos are being used and what she thinks about them. Good to get a student perspective. That would be great. Likewise to get that perspective from an XO class using the videos.

This looks promising, and should be resolved by the time any related projects or tools are finished. Among the larger deployments it would be good to hear from here are Ceibal and OLPC Oceania, both having expressed an interest in making KA videos more widely available to their students. From a usability standpoint, anyone using KA videos across a school or school system who has written about the experience would make an excellent point of reference. I will see if we can get in touch with someone who the Khan staff look to as a model.

Please add yoruself to the list of interested people on that page if you want to help out, or are already using KA videos in your schools. http://wiki.laptop.org/go/Khan_Academy Among the things this project could use: * A Linux port of the offline Khan Academy Web app (someone has already made a Windows version, complete with scripts that let you choose what subsets of videos you'd like to download). * A new XS build that includes a basic set of videos, or at least an installed version of this tool. * A translation coordinator to help synch up subtitling and dubbing efforts, most of which are currently scattered. -- Samuel Klein identi.ca:sj w:user:sj +1 617 529 4266 ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
