Feature requests for 11.2.0 - seeking deployment and community input
Hi, OLPC recently announced the development of a major new OLPC OS release for XO-1 and XO-1.5: http://wiki.laptop.org/go/11.2.0 We are seeking feedback and ideas from the community for feature requests for the upcoming feature development stage. Feedback from other parts of the community is welcome too. We're particularly interested in things that would make a big difference for deployments, solve big in-the-field challenges, etc. Please post any ideas here, and they'll be considered when we come to plan which features we'll aim to include. Features includes anything on the software level, really. From activities and UI to low-level system stuff. To give some examples, here's a selection of items from the last time that a feature plan was constructed: http://wiki.laptop.org/go/Feature_roadmap/Page_of_all_features_that_target_9.1.0 Thanks, Daniel ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

These files were for installing on SD cards with dd from Linux, used heavily before fs-update existed, but I suspect nobody uses them any more. If that assumption is wrong, please speak up and we can generate them by default again.

Re: 11.2.0 Test cases
greenf...@laptop.org said: I am starting work on a set of test cases to use for the Fedora 14 x86 (XO-1.0 1.5) 11.2.0 build. Neat/thanks. How about making a list of IO devices that are likely to be used with a XO and making sure they each get at least a quick test? It's probably worth collecting recipes that were used to demonstrate old bugs. The idea is that bugs tend to be in tricky sections of code and running the recipe again after the usual development churn is likely to tickle a new bug in the same area. It's a lot of work, but my experience many years ago was that it was embarrassingly effective. Is there a UI capture/replay mechanism? That might allow automating lots of testing. -- These are my opinions, not necessarily my employer's. I hate spam. ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: Feature requests for 11.2.0 - seeking deployment and community input
Please post any ideas here, and they'll be considered when we come to plan which features we'll aim to include. Well, the obvious one is to actually implement the real idle suspend that happens in between keystrokes, turning off the CPU to save massive amounts of power, while keeping the screen as it was. This was targeted for 9.1.0: http://wiki.laptop.org/go/Feature_roadmap/Page_of_all_features_that_target_9.1.0#Feature_roadmap.2FImproved_battery_life but it isn't clear how many of the numerous requirements actually got done. This particular bit is requirement 15 in the Improved battery life feature. This is one of the laptop's key innovations, designed to save massive power, allowing kids to use their laptops all day, even with the small and cheap battery that's designed in. It required significant rethinking, engineering, and testing of the hardware (DCON, etc) compared to other laptops, and OLPC actually did that. And yet to this day the software that would implement it for end users has never been delivered. John ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: [Sugar-devel] prevent screen rotation in a sugar activity?
Is there really no way to know when the Record activity is upside down on the 10.1.3 xo (and as a result xvimagesink in the wrong place)? Your question is a bit unclear so here are a few scenarios and answers. If you are looking to query what the current rotation of the screen is then you could use a python module like python-xrandr to query that property. Of course you could also get the dimensions of the gdk screen and compare width to height to gather that info as well. To know when a screen has changed you will need to attach a function to the GdkScreen's size-changed signal. Once you get that signal you could use either of the above methods to figure out the rotation and re-layout appropriately. There is nothing specific within Gdk that allows you to request a screen orientation. It has been a while but I believe that the Maemo guys added a window property that could be set to force a specific rotation. This could probably be implemented in sugar if really necessary. If you wait just a little while longer we are finishing the bits to get accelerated xvideo rotation finished. I hope one or all of these suggestions helps you fix your problem -Jon ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: foot power
Hey guys. I haven't taken that much look into foot pedal chargers and do know what their internals look like -- I just remembered coming across the link I posted so I shared The efficient way to do a foot pedal powered generator would probably be to have a small weighted wheel spin as a dynamo when you step on it? You just keep pumping on the pedal to keep the wheel spinning and it shouldn't take much effort, the wheel's momentum should keep power flowing. I have a small LED camping flashlight that does the same thing. There's a push grip on the side, and then when you squeeze it, it makes a wheel inside spin to generate power and it's pretty easy to use. Yep, raising your thigh with your toes down and stepping down with your heel is so much easier than pumping with the foot muscles. It doesn't take much effort and a number of people I know do it when they're excitedly thinking or discussing stuff when brainstorming while sitting down - push leg up with ball of foot, step down with heel. Well, how about this ridiculous idea? Hanging out in friends having fun thinking of hypothetical situations, one subject that came up was What if... we strap kinetic energy harvesting generators to kids when recess starts, then just letting them loose in the playground and put all energy to good use? - kinetic harvesters connected to small batteries to be charged, to be collected after playtime :) http://www.engadget.com/2008/06/24/oranges-dance-charge-finally-makes-dance-meaningful (I don't know what the internals of that thing look like) Anyway, basically, kids have so much energy and just it up when they run around having fun. Why not tap that as a power source? Q: how much power would something like that be able to harvest if you strap a few of them to someone playing basketball for 2 hours? Ideal placement would be angle and wrists as those will have the most motion. One of the bigger problems of that set up I think is that the forearms and feet generate so much force when rapidly changing directions that the device would break. (one I'm thinking of is something like one of my other camping flashlights - has a magnet in the middle, generates power when you shake it the magnet moves up and down the tube). -Naz -- carlos nazareno http://twitter.com/object404 http://www.object404.com -- core team member phlashers: philippine flash actionscripters http://www.phlashers.com -- poverty is violence ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

[Server-devel] Adding puppet to the school server.
Hey all, I just wanted to give everyone a heads up that Activity Central [1] is going to start working on a Dextrose Server project. For a little background, Dextrose [2] is Activity Central's primary product. Dextrose is based on upstream OLPC OS and Sugar. Most of what we do is a is a patch set on top of OLPC's repositories. These patches are submitted upstream for acceptance or rejection. The primary benefit of this is that it changes the emphasis of the development model from discussing how fixes or features _should_ be implemented to reviewing how a patch _solved_ a particular problem. Our initial effort will be to create puppet modules to enable deployments to remotely maintain and configure school servers. From a schools point of view, a School Server is a black box which provides various services including: 1. security -- 2. proxy -- 3. backup -- 4. collaboration -- Our initial goal will be create puppet modules to setup and maintain these key services. As a matter of work flow all of our work will be available as patches to upstream XS.6 andor XS.7. davidA 1. http://activitycentral.com/ 2. http://wiki.sugarlabs.org/go/Dextrose 3. http://www.puppetlabs.com/ ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
