gpiancastelli / google-fade.js

Created December 26, 2009 21:13

	/*
	Functions used for the fade-in effect on Google's home page.

	To reuse it, link this JavaScript file from your HTML source in a <script>
	element; then, set the onmousemove attribute of the chosen element (e.g. <p>,
	or <html> as Google did) to call the google.fade function.

	<html onmousemove="google.fade()">

	(Actually, Google setting is "google&&google.fade&&google.fade()". YMMV.)

gpiancastelli / goodreads-oauth-example.py

Created August 19, 2010 13:50

A Python example of how to use OAuth on GoodReads

	import oauth2 as oauth
	import urlparse

	url = 'http://www.goodreads.com'
	request_token_url = '%s/oauth/request_token/' % url
	authorize_url = '%s/oauth/authorize/' % url
	access_token_url = '%s/oauth/access_token/' % url

	consumer = oauth.Consumer(key='Your-GoodReads-Key',
	secret='Your-GoodReads-Secret')

gpiancastelli / tbd.py

Created November 9, 2010 15:34

A Python web scraper for wish lists on The Book Depository

	# A web scraper for wish lists on The Book Depository.
	#
	# TBD offers a mail notification service for books in a wish list when some
	# price drops. Unfortunately, you are notified only if prices drop of 10% or
	# more; also, the message you receive does not contain the new dropped price,
	# nor the old, higher price. Finally, when I got one of those notifications,
	# that very day I visited the book page on TBD only to discover that the price
	# got higher again. Not very effective as a service, you know.
	#
	# So I decided to write a script myself.

gpiancastelli / birthday.py

Created January 31, 2011 14:30

Calculate the probability of the birthday problem for 23 people on a user-supplied number of randomly generated samples.

	#!/usr/bin/env python2.6

	# In probability theory, the birthday problem, or birthday paradox pertains to
	# the probability that in a set of randomly chosen people some pair of them
	# will have the same birthday. By the pigeonhole principle, the probability
	# reaches 100% when the number of people reaches 367 (including February 29
	# births). But perhaps counter-intuitively, 99% probability is reached with
	# just 57 people, and 50% probability with 23 people. These conclusions are
	# based on the assumption that each day of the year (except February 29) is
	# equally probable for a birthday.

gpiancastelli / rot13.py

Created February 1, 2011 22:30

A basic ROT13 implementation in Python

	from string import lowercase, uppercase, maketrans

	if len(sys.argv) != 2:
	print 'Usage: %s text' % basename(sys.argv[0])
	sys.exit(1)
