Hey all,
The webcam on the XO sure has a lot of potential for cool killer apps.

Hey all,
Josh and I now made some speed tests with both 2D physics engines -
Box2D and Chipmunk - and here are some results. One warning though: The
tests were made with Python, and for Box2D there's a library compiled
with swig, whereas Chipmunk's interface is done with ctypes. This may

I'm just about implementing the script into xo-get, and I was thinking
on how to do it. Either simply integrating it into xo-get.py (xo-get is
a 1-file script),

Hey,
I've just finished making a xo bundle out of the physics thingy :) It's
a selection of the 3 last demos (6, 7 and 8). With not too many objects,
it's quite fun to play with :) Especially the drawing and behaviour of
polygons is always again fascinating. The activity (and project) is now

Yeah
Hey all.
Recently I did some research on 2D (SDL) physic engines, and found that
one of the most popular (called Chipmunk) with python bindings (pymunk)
recently got an update. I had a look into it, and am totally amazed :)
The chipmunk engine is easy, stable, fast, fun, open-source -- and now
Hey all,
I just wanted to inform you, that we have 3 Activities with the system
name "maze" (specified in activity.info). They are:
1. Maze
2. Jigsaw Puzzle
3. GCompris-Maze

bundles, there are some issues with xo-get, as i

As of currently, xo-get recognizes new gcompris activities with new
urls. I could imagine some data-exchange as a way for better future

Aah, this discussion had to be coming ... :p
I see the point that it's problematic to 'propagate' violent material on
an educational tool for kids 6-14. On the other side, censoring content
is problematic as well.
I feel strongly, that there should be a community discussion, *before*
removing
Well, yes - that's a known problem... It was sort of related to an error
in bundlebuilder, and that i haven't had enough time for hacking.
Basically, xo-get can deinstall all Activities from which you have the
source .xo file (exactly the one from the installation). Then you can
pass the filena
;./xo-get.py install gcompris'

Hey all!
I have updated xo-get to use http://wiki.laptop.org/go/Activities as
repository. The tool includes all activities with downloadable .xo
links, and follows [[Image:...]]-links to the real source. Currently
there are 43 Activities installable.
You can install xo-get this way:

Hi!
Mcfletch and I have been talking about the heavy cpu-load of the wiki's
pygame demo: 99%; and how to reduce it.
We figured out, a combination of pygame.event.wait() and
pygame.event.get() very good. That's the demo code; it takes less than
4% cpu (0.3% - 1.7% here):
