Python implementation of Conway's Game of Life
"""Python implementation of Conway's Game of Life
Somewhat inspired by Jack Diederich's talk `Stop Writing Classes`
http://pyvideo.org/video/880/stop-writing-classes
Ironically, as I extended the functionality of this module it seems obvious
that the next step would be to refactor board into a class with advance and
constrain as methods and print_board as __str__.

Getting started with testing in Python

Why Test

  • Tells you when your code is broken
  • Manual testing sucks
  • Prevent against regressions
    • Upgrading dependencies
    • Refactoring
  • Documentation
    • Other devs can read your tests to see how you intended your code to be used

A simple bookmarklet to add an alert feature to bitcoinwisdom.com :)
interval_id = high = low = null
ticker = $ '#price'
alert_url = 'http://www.angelfire.com/ut/jlpicard/images/picalert.wav'
start = ->
do nodes.stop.show
do nodes.start.hide
interval_id = setInterval ->
current_price = parseFloat do ticker.text
unless high > current_price > low
