Problem: When linking to the raw version of a gist, the link changes with each revision.

Solution:

To return the first file from a gist: https://gist.github.com/[gist_user]/[gist_id]/raw/

To get a file from multi–file gist: https://gist.github.com/[gist_user]/[gist_id]/raw/[file_name]

	#!/bin/sh

	# 404-check.sh - Script to test for 404s
	# author: lkptrzk

	# Usage:
	# Assuming a file named 'input' with one URL per line
	# the following command will output which files were 404s:
	# cat input \| xargs 404-check.sh

	function get_avatar_from_service(service, userid, size) {
	// this return the url that redirects to the according user image/avatar/profile picture
	// implemented services: google profiles, facebook, gravatar, twitter, tumblr, default fallback
	// for google use get_avatar_from_service('google', profile-name or user-id , size-in-px )
	// for facebook use get_avatar_from_service('facebook', vanity url or user-id , size-in-px or size-as-word )
	// for gravatar use get_avatar_from_service('gravatar', md5 hash email@adress, size-in-px )
	// for twitter use get_avatar_from_service('twitter', username, size-in-px or size-as-word )
	// for tumblr use get_avatar_from_service('tumblr', blog-url, size-in-px )
	// everything else will go to the fallback
	// google and gravatar scale the avatar to any site, others will guided to the next best version
