Plugin: state_select, generate drop down selection box for states

I have wrote my first plugin(state_select). This plugin allows to create drop down list for states, same as country_select method in rails. I know this is not a big deal…

Curently it can generate state list for India, US, Canada, Australia and Spain(default is US).

Usage:

• state_select(object, method, country='US', options = {}, html_options = {})

Return select and option tags for the given object and method, using state_options_for_select to generate the list of option tags.

• state_options_for_select(selected = nil, country = 'US')

Returns a string of option tags for states in a country. Supply a state name as selected to have it marked as the selected option tag.

NOTE: Only the option tags are returned, you have to wrap this call in a regular HTML select tag.

The svn repository can be found at http://opensvn.csie.org/state_select/trunk/

Install plugin by

script/plugin install http://opensvn.csie.org/state_select/trunk/

12 Balls Problem

You have 12 balls (of any kind), one ball either lighter or heavier than the other 11. A scale is provided to you but only three weighs are allowed. How can you possibly figure out which is the odd ball?
