    • Open design
      • The laptop's security must not depend upon a secret design.
    • No lockdown
      • There must exist a way for the security systems to be disabled for maintenance.
    • No reading required
      • Security cannot depend upon the user's ability to read a message from the computer.
    • Unobtrusive security
      • Whenever possible, the security on the machines must be behind the scenes.
  • 20. Bitfrost Goals
    • No user passwords
      • Users as young as 5 years old, cannot remember a password.
    • No unencrypted authentication
      • Authentication of laptops or users will not depend upon unencrypted data over the network.
    • Out-of-the-box security
      • The laptop should be both usable and secure out-of-the-box.
    • Limited institutional PKI
      • Keys will not be used to validate the identity of laptop users.
  • 21. Education
    • Its an education project, not a laptop project.
      • Nicholas Negroponte, Founder - OLPC
    • OLPC's Goal:
      • To provide children around the world with new opportunities to explore, experiment and express themselves.
    • Yes, but the laptop is way cool!
      • Sameer Verma, FOSS Enthusiast
  • 22. My compi
      • Mira Verma
  • 23. Building Content
    • Constructionism is a philosophy of education in which children learn by doing and making.
      • Electronic books created and stored on the school server
      • Collaborative activities
        • IM, Video, Music
      • E-toys
        • Build books with multimedia content
    • Think Lego®
  • 24. Learning outside the box
    • With sufficient self-confidence, teachers can learn from children without risk of unraveling the fabric of education—quite the contrary, improving it.
    • Children must not only own the laptop, but take it home. In so doing the whole family will benefit.
    • The child is not the object of change but the agent of change.
  • 25. Free and Open Source
    • FOSS was the only option that was flexible enough for this project
    • No vendor lock-in on formats
    • No royalties on redistribution
    • Perhaps the first example of a software project that has forced hardware manufacturers to modify their way of business.
  • 26. FOSS: What does it mean?
    • OLPC manifesto
    • Four freedoms
    • Open Source Definitions
  • 27. Richard Stallman's Four Freedoms
    • Freedom 0: The freedom to run the program, for any purpose.
    • Freedom 1: The freedom to study how the program works, and adapt it to your needs.
    • Freedom 2: The freedom to redistribute copies so you can help your neighbor.
    • Freedom 3: The freedom to improve the program, and release your improvements to the public, so that the whole community benefits.
  • 28. The Open Source Definition
    • 1. Free Redistribution
    • 2. Source Code
    • 3. Derived Works
    • 4. Integrity of The Author's Source Code
    • 5. No Discrimination Against Persons or Groups
    • 6. No Discrimination Against Fields of Endeavor
