Mission:

[[File:Dextrose-2-intl-logo.png|600px]] [[File:Dextrose-mascotte-120x96.png]]
Create and nurture a community of contributors with knowledge and experience developing for the XO. While raising raise the visibility and importance of the XO within the Sugar community.... without violating upstream/downstream abstraction barriers.  Instead the focus will be create an upstream community which evolves into a valuable contributor for OLPC.

== Project [[XO Operating System/Goals|Goals]] ==
 
  
Long term objective is to create a frequently released (every 6 months) community developed and supported distribution for the XO.  This would leave OLPC free to focus on the infrequent, stable releases necessary for mass deployment.

== The deployments' XO Operating System ==
  
The initial objective will be to:

Dextrose is a Sugar distribution for XO laptops jointly developed by Activity Central, [http://paraguayeduca.org/ Paraguay Educa], [http://www.ceibal.edu.uy/ Plan Ceibal] in collaboration with OLPC and the Sugar community.
1. Create daily builds
 
1a. Document the process of creating daily builds to lower the barrior of entry for new contributors.
 
2. Create XooS releases
 
2a. document the release cycle to lower the barrior of entry for new contributors.
 
  
== Dextrose - Deployments' XO Operating System ==
+
Our focus is stability and usability in the classroom, but we've also merged
 +
new features contributed by deployments and independent contributors.

== New features in Dextrose2 ==
  
Dextrose is a Sugar distribution for the XO-1 and XO-1.5. It is being developed jointly by [http://activitycentral.org Activity Central], [http://paraguayeduca.org/ Paraguay Educa] and [http://sugarlabs.org Sugar Labs], in collaboration with [http://www.ceibal.edu.uy/ Plan Ceibal] and members of the OLPC/Sugar community.

== Using this build with other deployments ==
 
 
 
A few customizations make this image somewhat deployment-specific:
 
 
 
* Limited language support: to save space, we've included only English and Spanish translations.
 
 
 
* Image signed with the Paraguay deployment keys. Laptops from other regions need to be unlocked in order to accept this image.
 
 
 
* The software update control panel icon checks for new activities on our wiki rather than on laptop.org.
 
 
 
* The Browse home page contains the Paraguay Educa logo and a few links to our website.
 
 
 
We may find the time to release slightly modified images to meet the
 
needs of other OLPC deployments interested in upgrading to Sugar 0.88.
 
 
 
More importantly, we're happy to help other deployments produce their
 
own OS images independently of us, thus exploiting the [http://www.gnu.org/philosophy/free-sw.html Freedom #1] provided by Free Software.

The deployments' XO Operating System

Dextrose is a Sugar distribution for XO laptops jointly developed by Activity Central, Paraguay Educa, Plan Ceibal in collaboration with OLPC and the Sugar community.

Our focus is stability and usability in the classroom, but we've also merged new features contributed by deployments and independent contributors.

Using Dextrose in your deployment
