My Neighborhood

I have 2 G1G1 XO.

My 3 year old grandson shares one with his mother, my daughter. My grandson is Spanish/English bilingual. My daughter teaches English in Mexico. My daughter, and my grandson took theirs to Zacatecas, Zacatecas, Mexico.

They need access to communities and libraries in both languages.

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 can 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 hides 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

would be great if there were service providers for most of the below

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 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 a couple 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.

OLPC News (Excerpts)

I want to move this to a personal pre-publication page and just leave links here in the User Discussion page.

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).

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.)
