== My Neighborhood ==


Apparently you have several XO users in the Seattle area. Did they buy theirs through last year's G1G1 program as I did? I have heard there is now a "GiveSome/GetSome" program. Can we designate where these XOs will go? And can we order less than blocks of 100?
I have 2 G1G1 XO.
I don't know any XO users in Denver. I have two XOs, but I have a group of earth scientists who are interested to invest in a critical mass of a dozen more XOs for training K-12 kids in Colorado. Can you advise me or do you know of a contact in Denverwho will help us?

My wife, an educator shares one with me.

I'm getting the infrastructure in place for a learning community with two sites.

'''Cool!!!''' we configure presence service from xochat.org

I STILL think I'll need my own school server.

=== Wish list ===

Structure My Neighborhood into zones. Want to be able to easily see
things of interest. Not yet thought whether this needs tweaking to
harmonize it with the Human Interface Guidlines

Connection Zone
Access points and mesh networks could be compactly displayed
in a small corner of the display.

Radio Zone
Folks in the G1G1 community may want to see
strangers who appear in their physical neigborhood

Internet Community Zone
Students with a rich local network mesh communities need to
clearly see guests who are joining the from remote locations
via a presence server.

Filter Zone
Hide folks
not participating in any activity
not participating in an activity I'm sharing
not a member of a group I belong to
not a member of specific group
etc.

distinguish these zones using
Shading of the background
spatial arrangement

== Learning Communities ==

organized by:

*Geographic regions
*Age groups
*XO activity
*Language
*Curricular Topics
*etc.

== Sugar on Conventional Desktop/Laptop ==

There are several ways to do it.
I have downloaded XO-LiveCD_071206.iso. I think I know most of what I need to know to do it with vmware. But I don't have the time energy.

And Matt Price says that's the wrong way to do it!
Glad I didn't waste the time and energy.
LiveCD

=== Sugar as application from repositories ===

This is probably the easiest from the user perspective,
kept up to date by the same processes that maintain the
rest of the user's system.

==== Packages from jani's personal archive ====

I distilled the following '''Gutsy Gibbon 7.10: command line''' example
from his posts in a Dec 29 OLPC emulation NEED LINK thread on the sugar mail list.
We need similar incantations for other tools and operating systems.
Adding '''Gutsy Gibbon 7.10: Synaptic Package Manager'''

Add jani's "repository" to your list of package sources.

Using your favorite editor add two lines to the file /etc/apt/sources.list

deb http://ppa.launchpad.net/jani/ubuntu gutsy main
deb-src http://ppa.launchpad.net/jani/ubuntu gutsy main

you also need to be sure that gutsy-updates is enabled, so make sure this line
is uncommented in the file:

deb http://archive.ubuntu.com/ubuntu gutsy-updates main restricted universe

Hmm!! I have:

deb http://us.archive.ubuntu.com/ubuntu/ gutsy-updates main restricted
deb http://us.archive.ubuntu.com/ubuntu/ gutsy-updates multiverse
deb http://us.archive.ubuntu.com/ubuntu/ gutsy-updates universe

not the same syntax and it enables the multiverse, too! I don't recall the provenance of my sources.list file, lots of things have been added for multimedia,
etc.

Gutsy: Command line

update the packages list:

sudo apt-get update

then install the whole environment with

sudo apt-get install sugar-emulator sugar-activities

Gutsy: Synaptic Package Manager

click the reload button

search for "sugar" (name and description) using Synaptic Package Manager,
check sugar-emulator and sugar-activities most everything else is selected to
satisfy dependencies. You may see other sugar activities you want to check.

note: In either case the update or reload takes a long time. Lots of failures NEED to understand and cleanup my sources.list.

look through the comments of jani's blog entries

http://janimo.blogspot.com/2007/11/try-sugar-xo-laptops-interface.html
https://edge.launchpad.net/~jani/+archive

remember there were some comments about additional packages that
needed to be installed for use on ubuntu. Maybe the ones indicated as prerequisites in the sugar-jhbuild instructions below.

=== Sugar jhbuild ===

My impression is that this technique is more likely to
result in broken, bleeding edge.

if that doesn't seem to work for you, you can build sugar yourself
without too much trouble;

in a terminal first execute the following:

sudo apt-get remove sugar
sudo apt-get build-dep sugar

then follow the build instructions from the olpc website:

http://wiki.laptop.org/go/Sugar_on_Ubuntu_Linux
http://wiki.laptop.org/go/Sugar_with_sugar-jhbuild

you may need to

sudo apt-get install git

to get things started.

I did this once a long time ago after PyCon 2007,
I'm sure it's much easier now.

remote desktop access on real XO using freenx.

=== Live CDs ===

In the short term this may be the easiest.

So far I have not found the right image

* stale
* bleeding edge
* worst of all bleeding edge and stale

Looking for release and pre-release versions:
* Ship.2
* Update.1
* etc.

Run on real hardware or in Virtual Machines.

== My School Server ==

my own school server
I have downloaded OLPC_XS_LATEST.iso


=== Services ===

==== Presence ====
We want to be part of larger community.

Presence service doesn't scale well.
See OLPC News (Excerpts)

Will the scaling issues be solved, and
will there be large servers to support the entire G1G1 community?
Or, will smaller communities have to form to spread out the load?

If so individual laptops will need connect to multiple presence servers?

In the meantime we are getting presence service from [http://xochat.org xochat.org]

==== Backup ====

on local server for privacy?

==== Library/Publishing ====

hierarchy:
school, district, region, country, global.

community based:
different levels of peer and/or expert review.

what libraries will the G1G1 community have access to?

==== Cache ====

bandwidth:
*Have cable modem in MX,
*Qwest ISDN in New Mexico, US.

cache might help even with only 1 or 2 users over a congested 128K link.
probably put school server at friend's with cable modem.
no bottleneck when all laptops are connecting via dsl or better.

would be great if there were service providers for all of the above.

== OLPC News (Excerpts) ==
I want to move this to a personal pre-publication page and
just leave links here in the User Discussion page.

=== 2007-12-15 ===

==== 9. Presence ====

Morgan has also continued to educate
G1G1 recipients on the lack of a single Jabber server that can handle
100s of thousands of them: we are hoping that people will point to
local Jabber servers that are set up for communities and special
interest groups (See
http://wiki.laptop.org/go/Ejabberd_Configuration).

=== 2007-12-22 ===

==== 8. School Server ====

We have encountered scaling problem with the XMPP service on the
server. The eJabber software runs out of memory over time as the
number of active users exceeds a hundred. Collabra is looking into
alternative server implementations. We had thought eJabber has used by
large instant-messaging services, but probably not with all the bells
and whistles we use. The XMPP service is crucial to the efficient
provision of presence information to laptops in a school through a
centralized method.

==== 21. Presence/sharing ====

Morgan helped some community people with Jabber questions
on the forums. There has been confusion about why the
ship2.jabber.laptop.org server doesn't work: Robert McQueen spoke with
people on IRC who were interested in trying ejabberd and helping us
work out why it was failing so badly. (There is now a server at
xochat.org that can be used instead of the default at
ship2.jabber.laptop.org. See the Sugar control panel page in the wiki
for instructions on how to configure your Jabber server.)
