This code iterates through every .html file contained in a given folder and, for each template found, it looks for every image (<img>) contained (with Nokogiri gem) in the document. Then it dynamically calculates the image size (with fastimage gem) adding the “height” and “width” attributes. Finally it saves the template. Colorize gem is only us…
# Tested on Ruby v.1.9.3 - Author: Fabrizio Calderan, 3.14.2013
#
# Install these gems with
# $> sudo gem install fastimage nokogiri colorize
#
# Then copy this source into a file named “rakefile” and run with
# $> rake
#
require "fastimage"
require "nokogiri"

An implementation of the problem B - Tidy numbers: Google Code Jam 2017
# Complete statement of the problem
# https://code.google.com/codejam/contest/3264486/dashboard#s=p1
# Tatiana likes to keep things tidy. Her toys are sorted from smallest
# to largest, her pencils are sorted from shortest to longest and her computers
# from oldest to newest. One day, when practicing her counting skills, she
# noticed that some integers, when written in base 10 with no leading zeroes,
# have their digits sorted in non-decreasing order. Some examples of this are 8,
# 123, 555, and 224488. She decided to call these numbers tidy. Numbers that do
# not have this property, like 20, 321, 495 and 999990, are not tidy.
