Re: [Server-devel] Is a Community Edition of XS happening? or should it?

Hello everyone,

Building upon some of George's statements, we are are currently in
what might be called a product development stage. This involves an
analysis of the needs of our stakeholders (schools, teachers, local
communities, etc.) and an evaluation of what we can do to solve these
needs. We have also consulted with some key OLPC/Sugar community
members in order to ascertain what is feasible in the technical realm.

We feel that taking such an approach is important before we can
develop a project plan and get stuck into writing code (we're writing
some now, but it's not a core focus). I don't think we're far off from
that. Also important is considering how this fits within the overall
engineering and educational strategy of OLPC Australia (that's not to
say that we're ignoring other deployments).

Some things that we know already about the XS and aim to address in our project:

  1. it is too monolithic
  2. it can be slimmed down and made more modular
  3. it can be installed as a set of packages (a repo) on top of Fedora
  4. it can be installed on an XO
  5. building on #3 and #4, it can be installed as packages on an XO's OS
  6. we can make it easy for a novice to install server components to
an existing instance of Fedora or OLPC OS
  7. we can automate much of the complication and make it easy to configure
  8. building on #6 and #7, it should be totally installable and
manageable by a non-technical person (e.g. a teacher)
  9. by installing on an XO, we can leverage some of the features (and
features we'd like to add) of Sugar too

If you'd like to participate, we're happy to have you. Our tracker and
code repo are open.

More to come...

I'm also pleased to see how much XS 0.7 has borrowed from our XS-AU
builds. It's great validation of our work thus far and encouragement
for us to take things further.

It's clear that XS development has not been able to receive enough
resources to maintain ongoing development at the pace that is needed.
I think that improvements can be made at a faster rate, and the user
adoption rate increased, if the XS is a set of packages on top of
Fedora (and, by extension, the OLPC OS).

Part of the problem here is that such decisions happen in a bubble,
over a Skype call or private e-mail. We had some conversations with
Cherry Withers about XS 0.6 back then, but then the e-mails never came
through the list. Even though the needs for all these deployments are
different (and may not be serviceable via one image) the conversations
need to happen on this list as much as possible.

 Adam Holt has been soliciting ideas from the support gang for finding a XS
 solution that just works.
 Jamaca is making Moodle central to its deployment strategy, but it needs
 some predictability in terms of school server depoyment.

For Jamaica, we are definitely leaning towards Moodle because of the
experience we have in house for Moodle. However, for a deployment that
does not have that expertise, Moodle may not be desireable. It should
be yet another check box on a list of things to install or remove.
Most deployments that say they use Moodle actually only use the XS
admin side of things that are now built into the XS version of Moodle.
Most deployments have no clue how Moodle works, let alone take
advantage of its capabilities.

 Tony Anderson and Abhishek Singh,in the Nepal deployment, have their own XS
 image tailored to their own needs.

Again, own needs are ok, because those are central for a deployment,
but without a loop in this forum, that's all unknown to the rest of
us.



 But I also think that the support that Boston has given to the XS has been
 essential. Daniel Drake's XS-0.7 brought together many of the improvements

We can definitely contribute in: 1) load testing any new builds and 2)
provide feedback from the field by actually using the XS and
collecting data.

 From my point of view, the challenge is to keep it simple, and to start
 working towards a structure where all of us can take a small piece, work on
 it, and contribute it back to the common effort.

I see it as a spectrum, where there is the XS design with all
components prepackaged and ready to go, but the downside is that you
have to use it as is with all the pieces. That's one end of the
spectrum. On the other end, if you want to use a server per classroom,
like what AU wants to do, or you have a deployment where curricular
model does not make sense (my India project -
http://bhagmalpur.wordpress.com/ - lives outside of the
classroom/teacher structure) one needs to be able to pick services
from a menu - Moodle, Pathagar, ejabberd, dhcpd, dns, etc and prune
the XS stack accordingly. Keep in mind that the current XS design is
based on what OLPC needs (and needed) in the field with its
deployments. The design may or may not address specific needs of other
deployments.

As for running the XS on a 1.5 or 1.75 the hardware makes sense, if
the size of the bubble is small enough. After all, the XO has a
screen, a keyboard, built-in battery, and power charge controller!
Piggyback a USB drive for storage, and you have a compact platform for
running services. Heck, most deployments have a couple of XOs all beat
up and cracked - perfect server candidates :-)

How small/large a bubble? We can help run the numbers and let you know
once we have a box up and running.

Whether the XS should be a
