It happens when the emulator crashes or is interrupted with Ctrl-C. sugar-presence-service and
sugar-clipboard keep running so a new registration is not possible unless those are killed
or avahi restarted.

And the emulator can crash when started from a cold cache as pyGtk tries to open a display and coredump

[sugar] active activity?

Hello

What is the preferred way for an activity to know & be notified if it is the
"current" / "in the frame" / "top of the stack" activity?

Maybe I should add a GTK listener on my activity (which extends
activity.Activity)?   If so, which one is recommended: has-toplevel-focus,
is-active?

Does this sound like the correct way to proceed?

Thanks,
Erik

This is also convient since we could handle where the laptops backup
goes server side, just by using the pub key and some authorized_keys
magic.

[sugar] rsync directory?

For now we are operating under the assumption that it is
/home/olpc/Journal/. This, of course, is subject to change as
configuration is added.

Are you working on some tools? Here is a silly rsync wrapper to get
things started...

Thanks Alex.  My sugar activities cannot mkdir new subdirectories in
/home/olpc/Journal/

Is there a preferred way to store files in that directory?

Hi Eric, I've been using focus-out-event/focus-in-event on the Activity
(gtk.Window). I think TamTam also uses that for pausing/resuming sound.

HTH,

I had access to a Dapper box today and I probably tracked this down
finally. It's a problem with the library search path. If you remove
-L/usr/lib or move it after -L/home/guido/xo/sugar-jhbuild/build/lib
linking should work.

I think we are going to add better support for this for BTest-3. Focus
in/out should work well enough until then though.

For Trial1 it will be the home directory. /home/olpc
