reviving XO-1 OS builds
Hi, I wrote some notes on how someone could build new OS images for XO-1 based on the ongoing XO-1.5 software efforts, and how this could be run as a community-driven process: http://wiki.laptop.org/go/F11_for_XO1 A fairly decent general knowledge of the Linux ecosystem is necessary, but it is not an overly difficult task. Anyone interested? Daniel ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: [Server-devel] [Sugar-devel] Collaboration Plan for the GPA tomorrow
On Mon, Jul 13, 2009 at 9:43 PM, Caroline Meekscarol...@solutiongrove.com wrote: We will be at the GPA tomorrow and we'll have time to test after class, probably around 12:30. So far all I have planned is to try getting rid of the jabber key on the master and try cloning some new sticks. We will also enable debugging following Dave's suggestion: To do that I edit ~/.Xclients to include this if [ -f ~/.sugar/debug ]; then . ~/.sugar/debug fi before eval \\\$(dbus-launch --sh-syntax --exit-with-session) Then we need to edit ~/.sugar/debug to fix a couple of typos: Missing space between exportGABBLE_LOGFILE and exportSALUTLOGFILE. It should be export GABBLE_LOGFILE... export SALUT_LOGFILE Are there any other suggestions? We got a hint from collabora that we should check the keepalive setting. Does anyone know what that is or how we could change it? There seems to be a separate bug that keeps local collaboration from working. Does anyone have any thoughts of what it might be or how to get more information? The debugging settings will also enabled logs for local collaboration, so hopefully that will give us the information we need. In fact it might also be related to the duplicated keys, but I don't know enough about the internals to say for sure.

Re: [Server-devel] [Sugar-devel] GPA School Visit report for Tuesday July 14
As Greg said we finally got collaboration working! The problem was that we had cloned the owner.key and owner.key.pub. The fix was to delete those before cloning and on existing sticks delete them and restart. This gives us solid collaboration inside the computer lab if we go local (take out the network setting). It gives us the seen frequently before, not so solid jabber collaboration. Most people can see someone some of the time but not everyone see's everyone. We will try to work with the local collaboration tomorrow. Sugar will be very hard for schools to scale until we have an easier way for teachers to create sticks for an entire class and we have a ticket in for this but I don't know if anyone is working on it. Caroline On Tue, Jul 14, 2009 at 4:35 PM, Greg Smith gregsmit...@gmail.com wrote: Hi All, I'm sending this to the devel instead of the IAEP list as it contains a number of technical/UI design comments that I think need developer follow up. Feel free to forward to other lists, blogs etc. as appropriate. Notes: I joined the team (Anurag, Caroline, and Bill) as the class of 22 x 2nd graders was leaving. This was their third class with Sugar/Turtle Art. They do it twice a week. As I got there I noticed a kid had unplugged their USB before full shut down and they were frantically trying to plug it back in while errors scrolled on the screen. Still not sure if they lost data (will check tomorrow on kid who made the same mistake last week). Is there anything we can do to ensure that all data is written/saved ASAP on clicking Shut down from the menu? The team told me that they worked with Turtle Art to load a map of the Charles River and to add tags to it showing where the GPA school is located. They said that some kids got it and some did not. Here's the warm/cold post class coments: Caroline Warm: More than half the glass got the idea of negative numbers and the gird (aka cartesian coordinates for placing turtle). A few got the idea of putting together a program. Cold: There was a large variance in kids who go it and those who didn't. Those who didn't understand got frustrated and they lost participation of about 1/3 of the class as a result. Bill Warm: A group of kids zero'd in quickly on the ideas of positive and negative. Cold: One USB was bad and that kid lost the flow and didn't catch up. Neutral: One girl finished right away and then didn't know what to do. Caroline said a few of the kids really looked like they could be programmers. Anurag Warm: All kids seem to be retaining what they learned in previous classes. Like how to put the turtle in the corner with Set (x,y). Lots of improvement from last week as a result like using show text, color, size. Lots of kids understood that 0,0 is in the center and that helped them find positions. Cold: Some kids lost focus because they didn;t understanbd the required order of operation in Turtle art (more below). Some built things then built other unattached programs which therefore didn't work together (e.g. show on the map then an un atached show text program somewhere else on the palette). Not enough time in the class. Other comments in debrief: The reality of teaching is time constrained. Next class we could just do the work for the kids who didn't get the GPA school noted on the Charles River map but they may lose a learning chance that way. Another option is to slow the class down, let kids who were done do something else and give the kids still working on the map more time. Kids seemed to think more this time rather than just clicking around a lot. Next class is Thursday. Goal is to put their pictures on the web. Comments that some kids don't understand the Journal/Keep paradigm which was introduced this time. An example: Sometimes they were in Turtle art and wanted to re-load an image from a previous instance. Many kids used the Turtla Art show tile (my turtle art is rusty so exact naming may be off). This allows clicking on it to open a Journal picker then clicking on it again (executing it?) shows an image of the last Turtle Art screen as seend in the Journal screen shot. What they really wanted was to just re-load the map in to the new blank Turtle Art screen. The suggestion was to rename the Turtle Art activity, then click Keep (I believe this step is not intended by Eben et al), then click stop, then open Turtle Art again, load the Kept instance from the journal. That's what my notes say but maybe Anurag and/or Caroline can clarify. Another tough work flow was getting the map in Turtle Art, scaling it then placing the turtle. The right work flow in terms of order execution of tiles in Turtle art is: - Move turtle to right place on screen - Set scale - Show map Many kids did this: - Show map - Set x,y of turtle - scale map Again, I'm not sure why the kids method is wrong but believe its a nuance of Turtle Art.

I have grave worries about the current 'clone a booted and hacked stick' without folks involved knowing all those first boot processes in detail – I just know enough not to want to try it in the first place :-) The current method I'm using of hand crafting a stick, going in and deleting files by hand, then cloning it is a total hack, hard to reproduce and very subject to human error. We need something like Ticket 74 where we have a real clone function that does the right things automatically. If we had that, and especially if it worked with a $15 USB hub to let you clone 4 or 6 sticks at a time, I think it would be far easier to have teachers do pilots. I really think that all of our current stick creation methods are too inefficient, inflexbile and human error prone to have many teachers with 20 to 30 kids in a class use them.
