Modulo Liquid filter for Jekyll

Got nested columns in your grid-based Jekyll site?

Wondered why you didn't have a way to calculate the modulo inside your posts loop to open and close your 'rows' containing those nested columns?

Add this filter to your _plugins directory, and use it like so:

{{ x | mod:y }}

class UrlValidator < ActiveModel::EachValidator
  def validate_each(record, attribute, value)
    record.errors[attribute] << (options[:message] || "must be a valid URL") unless url_valid?(value)    
  end
  
  # a URL may be technically well-formed but may not actually be
  # valid, so this checks for both.
  def url_valid?(url)
    url = URI.parse(url) rescue false
    url.kind_of?(URI::HTTP) || url.kind_of?(URI::HTTPS)

Standard Competition Rankings

This class makes it easier to generate a leaderboard that complies with the Standard Competition Ranking system. That is, it takes joint/tied positions into account, and adjusts the positions accordingly.

Take the following list of users and points for example:

User    | Points
1         35
2         35
