I couldn't find a more detailed introduction/manual for sugarbot; is there any ? - Does sugarbot supports working over more activities at the same time? - Can it automate the shell itself ? - Can it exec any arbitrary command (from a sb script), ie without needing to write them on the terminal activity? - If not yet, are these features planned ?

Re: [sugar] Google Summer of Code: sugarbot Screencast
Hi Riccardo, thanks for the interest. - Not yet. This is more of a limitation of the SimpleXMLRPCServer implementation than that of sugarbot.- Not yet. I am looking at using either DBUS or encapsulating the Sugar scripts to run inside a process I control. - No, but it would be quite trivial to implement. In fact, since the scripting functionality is moving to native Python code, you could do it in whatever manner you prefer.

[sugar] cursor jumpiness
G1G1; Q2D16; Joyride, manually updated to 2146. Just now experienced an episode of "jumpiness" with my cursor. What was unusual was that I was using an external USB mouse (and an external USB keyboard) -- my hands were nowhere near the XO touchpad. [By "jumpiness" I mean that for a small movement of the mouse, the cursor would "jump" to someplace further from the starting point than intended. Not sure about this, but some jumps might have been at an angle to the mouse movement.] I'm now thinking that some of the unexpected cursor behavior that many have noticed - might come not from variances in SENSING the user's input, but rather from variances in INTERPRETING (in software) the sense data that had been received. Or it might even be due to "interference" having corrupted the 'sense data' from how it had actually been reported by the input device. [I have no reason to think that my (optical) mouse suddenly started emitting "position" information differently. Normally, my XO cursor moves smoothly when I move my mouse.] mikus ___ Sugar mailing list Sugar@lists.laptop.org http://lists.laptop.org/listinfo/sugar

Ping -- where can I find more information on activity numbering? I chose 0.1-1.0-x.x style numbering because it reflects 1.0 being when I believe the activity is ready for deployment. I hope this intended meaning is preserved in any suggested version numbering standards. Things that might be nice to also include on any activity numbering scheme: - 1.0 is special - when to hold the release party - testedness / ready-for-classroom? - major / minor changes Brian > > - Eben > > > On Thu, Jul 10, 2008 at 6:41 PM, Michael Stone <[EMAIL PROTECTED]> wrote: >> Please remember that activity version numbers must be integers.

Re: [sugar] [OLPC-Games] Physics -- Newtonian mechanics.. for kids!
Hi Yoshiki, These are great! I've added them to http://wiki.laptop.org/go/Physics_(activity) . Feel free to add more yourself via the upload mechanism: http://wiki.laptop.org/go/Special:Upload ! A priority is XML-format scene saving, so we can share great scenes like yours and those that will be made in the future. Physics is not "ready for deployment" until scenes can be saved and shared.

The elasticity isn't >> > right for it, it seems. Yoshiki, Edward -- Physics is currently contstrained by capabilities of the open source Box2D physics library. Any added engine capabilities should be added upstream to their project. See http://www.box2d.org , and there is a thriving development community (and the project founder/main coder responds to forum questions) http://www.box2d.org/forum/ Box2D Manual - http://www.box2d.org/manual.html - covers (most of) the capabilities of Box2D Erin Catto's Box2D GDC 2005, 2006, 2007, 2008 slides: http://www.gphysics.com/downloads For visualizing concrete possibilities (i.e., easy-to-access projects using Box2D or ports of Box2D): http://box2dflash.sourceforge.net/ - Actionscript 3 Box2D I tried this on the XO with the latest joyride in gnash... it wouldn't load. Will somebody please try with Flash? http://jbox2d.org/ - Java box2d... made by my brother :) No chance of working on the XO any time soon. http://box2d-js.sourceforge.net/index2.html - Javascript Box2D - actually has the 5-ball pendulum you describe, in addition to a cool motorjoint-based ball-paddling/juggling device I tested JS on the XO with the latest joyride -- it ran reasonably with two objects, unreasonably slow with three. I will be adding contextual menus (time-based... see Paint for an example) to the tool selections so you can change friction, elasticity (Box2D: restitution), mass (Box2D: density), color, etc of each element before (and maybe eventually after) adding. These are all supported in Box2D. >> >> What does it do? Can you get it to tell you what values of momentum >> and energy are passed through from balls 1-->2-->3? > See again the Box2D manual, MANY things are possible. I think, interestingly, once we add diagnostic information (visual--using colors and force-lines, auditory--using force-variable volume sound effects, and graph-able data graphing or storage) to Physics, many more opportunities for self directed learning arise. I appreciate very much any ideas (or code) that solves the difficult challenge of displaying and letting kids play with this data they are generating just by their use of Box2D. I am glad others understand the implications this amazing open source engine will have on learning Physics. :) http://wiki.laptop.org/go/Physics_meetings/July_10%2C_2008 We had a (disorganized, last-minute) meeting yesterday to discuss next steps for the OLPC Physics community. We are looking into making movement drawing faster on the XO (as it seems, surprisingly, to be our limiting Physics performance factor), a common format between our collective physics playgrounds, and involving developers of other (many closed source) physics engines to consider helping us and, in some cases, Box2D. http://wiki.laptop.org/go/User:Bjordan/Ideas/Teacher_involvement#Physics Cheers, Brian Ahh, the importance of having a working demo... :) > Heh, of course you can try by yourself.

Yes, that would be fantastic. I will ask the other OLPC-physicists about their availability around that time, as well!
