I've implemented and tested the above change, and attached it to the

I've no patch yet.  I've looked into what would be required.  There are
two possibilities:

1.  change to shell service D-Bus API GetBundlePath to have it do a
second search if a search by bundle id fails, so that it can be used to
obtain a bundle path by case blind substring of bundle id, also failing
if it encountered more than one match,

2.  directly call the bundleregistry from sugar-launch using
get_registry, which would look easy but would load all the activity
metadata into the sugar-launch process and then discard the result of
that effort.

NP. Great if you can give it a check.

All that code has been reworked in 0.84 and later, and the workaround
is no longer needed in the F11 builds anyway, so it's a short-lived
patch. Uy team has confirmed it solves the issue on their setup, and
so I am happy.

What it did uncover (for me anyway) is that 0.84 and possibly later
Sugars have several issues talking with NM in the "Sugar is a
configuration server for NM" interaction. Looks like Sugar still
cannot convince NM to take the new passphrase, and that
enabling/disabling encryption breaks things.

See http://dev.laptop.org/ticket/9977 and http://bugs.sugarlabs.org/ticket/1674

Here's an unlikely option...

When I couldn't get cinelerra to work, back in the day, I ended up  
resorting to:

http://lvempeg.sourceforge.net/

Which is pretty much unmaintained for the past 5 years, so far as I  
can tell, so probably no use here.
On the other hand, it worked OK on the low spec hardware I had  
available at the time (which might be relevant) and the code seemed  
reasonably understandable...

In Fedora 11, this is the ouput of yum search hulahop:

Sayamindu,

I actually did turn off the firewall.  It didn't seem to help.  I used
another box running Fedora 10 for the examples in the book and that
worked fine.

I don't think there have been changes in Chat in this direction.

If you are using a stock F11 install, you may need to change your
firewall settings for collaboration to work via Salut. I remember
having to switch off the firewall via system-config-firewall at some
point.

[Sugar-devel] New version of Making Sugar Activities for review

2010-02-15 Thread James Simmons
The link is here:

http://objavi.flossmanuals.net/books/ActivitiesGuideSugar-en-2010.02.15-18.18.25.pdf

I finished the chapter on Making Shared Activities.  I had originally
planned to write a simple Activity to demonstrate DBus Tubes but
instead I decided to show how to get the Scribble and Batalla Naval
Activities working in sugar-emulator and described how they worked in
some detail.  I'd like more knowledgeable developers to check out that
chapter and let me know if I hit or missed the Barco.

I still can't get Salut collaboration working in Fedora 11.  If I knew
how to fix the problem I'd add the information to the chapter.

I'm going to do a couple of short chapters next.  One will be on
debugging Sugar Activities and the other will be suggestions for
further reading.  Once those are done I'll probably ask for the book
to be put on the front page of Floss Manuals, probably using the title
"Making Sugar Activities" rather than "Make Your Own Sugar
Activities!" (which I still prefer) because the site does not
currently deal well with titles of more than three words.

Other chapters will follow after that, including New Toolbars and
PyGame at least.  There are a *lot* more topics you could put in a
book like this and I'm still hoping some of you will want to write the
chapters I'm not qualified to do, like:

Sugarizing existing programs
Writing Activities In Languages Other Than Python
Hulahop
etc., etc.

Cinelerra is a quirky beast, designed for high end hw, with lots of UI

May be it can be turned into the opposite of what it's been for the

One thing you didn't mention, that I have been working on (but won't
finish for 0.88) is adding graphical skins to blocks so that we can
optionally eliminate the words. I have most of the underlying
mechanics in place--just haven't worked out the UI issues yet.

Working on adding a While block. It is a little trick as I have to
keep the bool around to reevaluation.

Color under the turtle I hope to add when I switch over to Cairo (the
current canvas style is write-only).
