Matt Meyer's excellent introduction to Unicode.

For fun, I thought I'd implement Evan Miller's Ruby function to calculate the lower bound of Wilson score confidence interval for a Bernoulli parameter using Perl. Here's what I came up with:

#!perl

# Author: Phil Quinn
# Date: 3 April 2012
# Exploring confidence of rating systems
# based on http://evanmiller.org/how-not-to-sort-by-average-rating.html
# Lower bound of Wilson score confidence interval for a Bernoulli parameter


var foo = {
methodbar: function () {},
methoddoo: function () {},
methodray: function () {}
};
