Personal Note-taking

To Do

1. read about Hacking the OLPC
2. Learn how to insert special foreign characters, such as Spanish accents and tildas
3. Update the built in Spanish dictionary that is accessible via the Browse activity. Currently the gender of each noun is unknown. This is easily fixed by preceding each noun with el or la.
4. Read this: bunnie's teardown report
5. Read this: Interview with OLPC's Founding CTO Mary Lou Jepsen, by Sean Daly

Ideas

• Clock activity. Description forthcoming.
• Hand-made vinyl or fabric sleeve for protecting the goods.
  • Something like this idea
  • Publish the patterns and instructions in an instructable
• Math app that demonstrates neat tricks with numbers (in Spanish, trucos magicos), e.g.
  • helpful tricks for factoring numbers:
    • If a number is even (un par en espanol), then it is evenly divisible by 2.
    • If the sum of the digits of a number is a multiple of 3, then it is evenly divisible by 3.
    • If the sum of the digits of a number is a multiple of 3 and the number is even, then it is evenly divisible by 6.
    • If the last digit in a number is either 5 or 10, then it is is evenly divisible by 5.
    • If the sum of the digits of a number is a multiple of 9, then it is evenly divisible by 9.
  • Techniques for mental math operations
    • To multiply a number by 5, divide it by 2 and shift the decimal one place to the right.
    • break up numbers into parts to do easier arithmetic operations, and combine the partial results
      • (examples to come)
• extend the idea of a wiki website with widgets that each perform a specialized function such as
  • vote collecting
  • advertising goods and services (the craigslist.org widget)
  • scheduling (group calendar widget)
  • flow charts for plans, instructions or troubleshooting
• External HW peripherals
