Personal Note-taking

To Do

1. Update os to the most recent stable build. see Stable_Upgrade
2. 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.
3. Read this: bunnie's teardown report
4. Read this: Interview with OLPC's Founding CTO Mary Lou Jepsen, by Sean Daly

Done

1. Requested my Activation_and_Developer_Keys
2. Connect my XO to home network.

Ideas

• Clock activity. Description forthcoming.
• Hand-made vinyl or fabric sleeve for protecting the goods. Something like this idea
• 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)
