  1. One Laptop per Child One Laptop per Child Software Roadmap May 20, 2008

  2. Software Technologies • Many new technologies in one laptop: • Power Management • Mesh Networking/Collaboration • Sugar User Interface • Datastore and Journal • Security • Infrastructure Support • School Server • Power devices

  3. Creating the Roadmap • Gather feedback • Prioritize features and bug fixes • Evaluate the work effort • Determine the resources and time frame • Come up with Roadmap

  4. Gather Feedback • Feedback from: • Deployments (teachers, administrators, technical) • Uruguay, Peru, Mongolia, others • Market Development (sales/marketing) • G1G1 program • Support • Community: Educators and Developer

  5. Prioritizing the Work • Fix Touchpad • Improve Keyboard tearing problem • Getting Started Guides, Videos, Manual • Easier XO upgrades • Better battery life • More reliable activity collaboration • XO backups to school server

  6. Prioritizing (cont) • Sugar UI performance, Browse features • Preload Flash • Sugar emulator for training • Journal/Datastore fixes and enhancements • User or teacher defined ‘groups’

  7. SW Release Roadmap Nov 2007 Mar 2008 Aug 2008 Jan 2009 • Major release every 4-5 months • Minor or bug fix releases in between • Developer builds available continuously b653 b656 8.1.1 8.2.1 Ship1, b650 8.1.0 (Update.1, 703) 8.2.0 9.1.0

  8. SW Release Roadmap Nov 2007 Mar 2008 Aug 2008 Jan 2009 • 8.1.0 - power button suspend; first level activity isolation (security); bug fixes; wifi solution for >20 laptops • 8.2.0 - improved collaboration/mesh, some improvement in battery life, UI response, XO backups • 9.1.0 - better scalability with collaboration; dynamic suspend/resume (battery life); robust, reliable datastore b653 b656 8.1.1 8.2.1 Ship1, b650 8.1.0 (Update.1, 703) 8.2.0 9.1.0

  9. Power Management • Available today: • Hardware ready for suspend/resume • Update.1 has support for sleep on lid close or button • About 4 hours of battery life during normal use • 14-16 hours of battery life in sleep mode • Future: • OHM management for suspend/resume • eBook mode to >10 hours • Aggressive CPU suspend

  10. Mesh and Collaboration • Available today: • 802.11b/g - via infrastructure access point • Small groups of simple mesh, wifi school server • Collaboration in small groups • Future: • Track 802.11s evolution, address scaling, develop robust middleware/APIs • Corner cases - many students start up at once • More robust server process for sharing outside of local mesh • Better sharing at activity level

  11. User Interface • Available today: • Views: Home, Group, Neighborhood, Activity • Frame: People, Places, Objects, Actions • Emphasize collaboration and simplicity • Invite or share activities with others • Future: • Better performance • Flesh out the concept of Groups or Friends • Support for other desktops (KDE, Gnome) • Port to other platforms (HW and OS)

  12. Datastore / Journal • Available today: • How docs are created; by whom • Easy use; auto save • Chronological list of activities/objects • Future: • Scaling and Robustness • Bulk file transfers, transfers outside of the Journal • Versioning, XO to XS backup

  13. Security • Available today: • Signed software (both OFW and OS) • Activities isolated from filesystem • Linux desktop • Future: • Anti-theft of the delivery chain - activation lease • Activity isolation from network, Address root access issues • Passive and Active kill • Activity signing, Identity authentication

  14. XS School Server HW / AP • XS Hardware Specifications: • 1GHz+ x86 processor, 1+ GB main memory • Four to six USB interfaces and an external disk drive • One 300-500GB+ 3.5in SATA drive • Power and space for a second disk drive • Two 100baseT network interfaces • Cost: approximately $600 - $1000 USD (or more) • Access Point Specifications: • 802.11b/g • Zoom 4400 has been tested at OLPC • Cost: approximately $40

  15. XS School Server SW • Available today: • Fedora-based OS; standard services (DHCP, DNS, Apache, uplink) • Web cache, local content and upgrades for XOs • Presence server for collaboration • Future: • XO backup/restore to XS • Remote management of XS • Filtering, Scalability
