miketierney / Windows Hosts File

Created March 23, 2009 22:11 — forked from wanderingmatt/Windows Hosts File

	# Copyright (c) 1993-1999 Microsoft Corp.
	#
	# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
	#
	# This file contains the mappings of IP addresses to host names. Each
	# entry should be kept on an individual line. The IP address should
	# be placed in the first column followed by the corresponding host name.
	# The IP address and the host name should be separated by at least one
	# space.

miketierney / image_resizer.rb

Created April 30, 2009 20:45

	def image_resizer max, height, width
	# capture any nil or 0/less-than-0 objects and set them to the max value, since they need a value.
	# Assume max size is desired unless we're told otherwise.
	height = height.nil? \|\| height <= 0 ? max : height
	width = width.nil? \|\| width <= 0 ? max : width

	# Find out if any of the dimensions are bigger than the max size
	if height > max \|\| width > max
	# isolate the largest dimension -> it doesn't really matter which one we look at, as long as it's the largest
	largest_dimension = height > max ? height : width
