[Server-devel] EduBlog Revised Project Plan

I appreciate your flexibility. However, a key requirement is to include
the app in a future XS build when customer demand is proven. Nothing
goes on the XS without your OK so let's keep talking until we reach
My top concern with requiring Moodle for August delivery is that no one
has Moodle yet. Do you know of any plan to install Moodle in
Ceibal/Uruguay? Of course, no one has EduBlog either. Maybe we can do
the Internet hosted version (AKA Tony's box) with Moodle and declare
Phase 1 success that way. We need a final OS + XS build to install by
I want to hear Tarun's evaluation of Moodle integration and code re-use.
The primary motivation for the project is to simplify posting to
blogger.com. If I don't nail that in August we haven't shown
responsiveness to the customer.
They also want to interface to other blog tools and Moodle is high on
the list. Just not sure it will be closed by August.
My secondary concern is that many programmers know how to build Apache +
Script + DB Web Apps (LAMP if you will). If we can say "LAMP skills is
all you need to build dynamic XS hosted web sites for XO" that's a big
plus. Its tougher if we add "must know, install and configure Moodle" or
worst case "must modify Moodle source". Better if we recommend and doc
sharing resources with Moodle (e.g. DB and auth) but otherwise build
your own web app.
That's my thinking but I'm not a code designer/architect. I'll get out
of the way and let's see what Tarun thinks he needs to meet the defined
I still need a simple front end GUI to help me promote the core idea but
I can wait if we're making progress in other areas.
I have to focus on customer side for a while so have at it and let me
know what you think is the best way to satisfy the requirements:

Yes - that's a pretty important thing. And leads into a second thing
that is tricky - if you want Edublog to work on both infrastructures
(Ceibal's school server and the standard XS) we need some coordination.
Otherwise you'll end up with htings that work only on one.

If you go down this path you are turning your back on my
recommendations. I can't really help much, and it will be *much* harder
to get it on the XS.
You are doing some fantastic thinking on the product side of Edublog -
perhaps you could get the programmers discussing the technical aspects
on this list, with me directly? I am more than happy to mentor and help.

We need to sort out the very tricky technical details of identity
management on XS and the Ceibal school server. We can all discuss it via
email with the Ceibal team, I would not want it to be mediated (in other
words - don't try to mediate on technical matters unless you are the
programmer writing the code! :-) )

Yes yes and yes to all that.

And here you have your XS architect telling you: you don't write new web
apps for the XS. To build a "web app" you add take something that
exists, is secure, scalable, solid, maintainable, etc, and you extend it
or tweak it.
Want it *really* easy? Turn this plan into
- install moodle (trivial!)
- read through the code of the blog facility
- add a "forward blog post" feature to moodle's blog (there, you are
ready for early deployments)
- simplify UI a bit (which we have to do anyway)
the "forward blog post" feature, if well done, can get integrated
upstream. And it's a simple thing - all the needed facilities are in
place, at most we'll need an additional column in a table.
One of the most common rookie programmer errors is to write your own
thing. Easy to get started, impossible to reach the goals. Don't make
this mistake - what we want here is to reach the goal. The "easy start"
is only apparently easy.
In any case, you still want to do it your way, well. I can't stop you,
but my experience is that the end result is very unlikely to meet the
requirements for inclusion on the XS :-/
