Learn Robotics resources

I’ve ordered a robot on Robotshop.com. It’s almost 2 months they’re trying to get all the pieces of my huge order, but it seems like it’s coming soon. Meanwhile I’ve started gathering resources for education:

Javascript weirdest features

  1. typeof Array returns ‘object’
  2. typeof null returns ‘object’
  3. var n = [4, 8, 15, 16, 23, 42];
    n.sort( ); // n is [15, 16, 23, 4, 42, 8]
  4. parseInt(“08″) = 0, because js thinks that the number has base 8.
  5. 0.1 + 0.2 is not equal to 0.3
  6. typeof NaN == = ‘number’ // true
    NaN === NaN // false
    NaN !== NaN // true
  7. ‘ ‘ == ’0′ // false
    0 == ‘ ‘ // true
    false == ‘false’ // false
    false == ’0′ // true
    false == undefined // false
    false == null // false
    null == undefined // true’ \t\r\n ‘ == 0 // true

Closure in Javascript

Trying to stimulate me to begin starting to push myself to learn Javascript. This is the buggest language I’ve met, it was invented like in 10 days with some great concept and even more great caveats.

Started reading Test-driven javascript development, but ocassionally stopped: too obfuscated for a beginner. Now trying to make Javascript: Good Parts by Douglas Crockford.

The first hard thing supposed to be Closures. But here is the great article on this topic: http://blog.morrisjohns.com/javascript_closures_for_dummies.html

Hope it will go easier from now on.
