Dextrose - Deployments' XO Operating System
Dextrose is a Sugar distribution for the XO-1 and XO-1.5. It is being developed jointly by Activity Central, Paraguay Educa and Sugar Labs, in collaboration with Plan Ceibal and members of the OLPC/Sugar community.
The focus of this build is stability and usability in a classroom environment. While there wasn't much time for new development, we've merged a few features contributed by other deployments and freelance contributors:
- Journal sorting options (aa)
- CPU/Memory display (m_anish)
- Journal Backup/restore to removable devices (tch, esteban)
- Journal Backup/restore to schoolserver (tch)
- Tabbed browsing (m_anish)
- OLPC Microformat support in activity updater (gangil) (pending)

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 Freedom #1 provided by Free Software.
