Hi

If you haven't picked out what to do tomorrow, you could consider the new
Dextrose build.

Kind regards

This release of Dextrose 2 is intended for beta testing. Images for the
XO-1 and XO-1.5 can be downloaded here:

 http://wiki.sugarlabs.org/go/Dextrose

I've not bothered uploading GNOME-enabled images, since Paraguay does
not use it. I could be convinced to generate them if it's needed by a
deployment for evaluation purposes only.

The major highlight in this release is a simple automated updater based
on yum which will hopefully enable us to deploy small updates
effortlessly. The final release should be ready by Feb 22, when schools
reopen in Paraguay, and if the updater works well we'll be able to fix
any remaining bugs post-release. This build also includes a refresh of
the new activity updater which supports the "OLPC microformat" protocol.
Please test both these features vigorously.

This release is missing several Sugar fixes that went into OLPC 10.1.3
over the last weeks. The queue of patches waiting to be merged in
Dextrose is quite long and new features have to take precedence so they
can get tested early on. We also have some small features that we hope
to merge in time for this release. Consult the todo list for more
information.

Is an .xo bundle of Record-87 available anywhere?

It's not yet posted at activities.sugarlabs.org.

It's here: http://people.sugarlabs.org/anish/Record-87.xo

This version contains a kludge to fix for the UI layout on Sugar 0.88
and on any non-1200x900 display.

The current maintainer of Record, Daniel Drake, requested a complete
rewrite of the UI, but nobody so far has had the time to work on it.

At this point, I think we should just admit that the proper fix isn't
going to happen anytime soon and go with the current kludge. Daniel, how
do you feel about it?

Bernie,

Thanks for this info. I can report that Record-87 acts like v86 in that it
does not allow for audio recording. In both cases, when you hit Stop
following recording, the activity seems to get lost during the save process
and never reemerges. You can close the activity, but that's all.

FWIW, I've copied the logs for both v86 and v87. One difference I noted is
that the v87 activity icon gets stuck in "Starting..", whereas I don't think
this is the case with v86. It looks like both versions saved correctly and
then got sidetracked. (I gave both runs several minutes or more time to
"recover" from saving.)

I continue to be very concerned about Record because, to my knowledge, *with
versions of SoaS higher than Strawberry*, no Record produces Ogg Vorbis
sound recordings (one or two produce Ogg Speex, which of course are both of
lower sound quality, and are not handled by Csound). For certain, starting
with Record-76, *all* should produce Ogg Vorbis.

Congrats!
Interesting. Any pointers to how it works / design and or src?

cheers,

As soon as we're finished with this release cycle, we'll get started on
Fedora 14 or 15 with Sugar 0.90 or maybe 0.92. We'll pick the same
versions that OLPC chooses, to maximize synergy.
It's a very simplistic tool: This was the initial design by Aleksey:

 http://wiki.sugarlabs.org/go/Dextrose/Updater

This is the actual code being deployed:

http://download.sugarlabs.org/dextrose/testing/dxo2/rpms/source/dextrose-updater-1-6.fc13.src.rpm

Our hope is that, with a small data set, yum will perform decently in
the field, even on the memory starved XO-1.

We'll issue updates sparingly, from a deployment-controlled repository.
Even if something goes wrong on 1% of the machines and we need to
upgrade them manually with USB sticks, we would still save 99% of the
work.

Flash filesystems get corrupted occasionally in the field, therefore the
only way to avoid data loss is having good backup/restore procedures. A
fail-safe update system alone is not sufficient.

Another thing I like about the yum-based solution is that it doesn't
require an arcane filesystem layout and home-brew tools such as
olpc-update. One less thing we have to maintain separately from Fedora.
