Green <ul><li>Looks green, works green </li></ul><ul><ul><li>Fully recyclable </li></ul></ul><ul><ul><ul><li>5 year life span </li></ul></ul></ul><ul><ul><li>Idle power consumption </li></ul></ul><ul><ul><ul><li>Desktop – 80 watts </li></ul></ul></ul><ul><ul><ul><li>Laptop – 20 watts </li></ul></ul></ul><ul><ul><ul><li>OLPC – 1 watt </li></ul></ul></ul>

  11.

  19. Bitfrost Approach <ul><li>Open design </li></ul><ul><ul><li>The laptop's security must not depend upon a secret design. </li></ul></ul><ul><li>No lockdown </li></ul><ul><ul><li>There must exist a way for the security systems to be disabled for maintenance. </li></ul></ul><ul><li>No reading required </li></ul><ul><ul><li>Security cannot depend upon the user's ability to read a message from the computer. </li></ul></ul><ul><li>Unobtrusive security </li></ul><ul><ul><li>Whenever possible, the security on the machines must be behind the scenes. </li></ul></ul>
  20. Bitfrost Goals <ul><li>No user passwords </li></ul><ul><ul><li>Users as young as 5 years old, cannot remember a password. </li></ul></ul><ul><li>No unencrypted authentication </li></ul><ul><ul><li>Authentication of laptops or users will not depend upon unencrypted data over the network. </li></ul></ul><ul><li>Out-of-the-box security </li></ul><ul><ul><li>The laptop should be both usable and secure out-of-the-box. </li></ul></ul><ul><li>Limited institutional PKI </li></ul><ul><ul><li>Keys will not be used to validate the identity of laptop users. </li></ul></ul>
  21. Education <ul><li>Its an education project, not a laptop project. </li></ul><ul><ul><li>Nicholas Negroponte, Founder - OLPC </li></ul></ul><ul><li>OLPC's Goal: </li></ul><ul><ul><li>To provide children around the world with new opportunities to explore, experiment and express themselves. </li></ul></ul><ul><li>Yes, but the laptop is way cool! </li></ul><ul><ul><li>Sameer Verma, FOSS Enthusiast </li></ul></ul>
  22. My compi <ul><ul><li>Mira Verma </li></ul></ul>
  23. Building Content <ul><li>Constructionism is a philosophy of education in which children learn by doing and making. </li></ul><ul><ul><li>Electronic books created and stored on the school server </li></ul></ul><ul><ul><li>Collaborative activities </li></ul></ul><ul><ul><ul><li>IM, Video, Music </li></ul></ul></ul><ul><ul><li>E-toys </li></ul></ul><ul><ul><ul><li>Build books with multimedia content </li></ul></ul></ul><ul><li>Think Lego® </li></ul>
  24. Learning outside the box <ul><li>With sufficient self-confidence, teachers can learn from children without risk of unraveling the fabric of education—quite the contrary, improving it. </li></ul><ul><li>Children must not only own the laptop, but take it home. In so doing the whole family will benefit. </li></ul><ul><li>The child is not the object of change but the agent of change. </li></ul>
  25. Free and Open Source <ul><li>FOSS was the only option that was flexible enough for this project </li></ul><ul><li>No vendor lock-in on formats </li></ul><ul><li>No royalties on redistribution </li></ul><ul><li>Perhaps the first example of a software project that has forced hardware manufacturers to modify their way of business. </li></ul>
  26. FOSS: What does it mean? <ul><li>OLPC manifesto </li></ul><ul><li>Four freedoms </li></ul><ul><li>Open Source Definitions </li></ul>
  27. Richard Stallman's Four Freedoms <ul><li>Freedom 0: The freedom to run the program, for any purpose. </li></ul><ul><li>Freedom 1: The freedom to study how the program works, and adapt it to your needs. </li></ul><ul><li>Freedom 2: The freedom to redistribute copies so you can help your neighbor. </li></ul><ul><li>Freedom 3: The freedom to improve the program, and release your improvements to the public, so that the whole community benefits. </li></ul>
  28. The Open Source Definition <ul><li>1. Free Redistribution </li></ul><ul><li>2. Source Code </li></ul><ul><li>3. Derived Works </li></ul><ul><li>4. Integrity of The Author's Source Code </li></ul><ul><li>5. No Discrimination Against Persons or Groups </li></ul><ul><li>6. No Discrimination Against Fields of Endeavor </li></ul><ul><li>7. Distribution of License </li></ul><ul><li>8. License Must Not Be Specific to a Product </li></ul><ul><li>9. License Must Not Restrict Other Software </li></ul><ul><li>10. License Must Be Technology-Neutral </li></ul>
