	#!python
	def savitzky_golay(y, window_size, order, deriv=0, rate=1):
	r"""Smooth (and optionally differentiate) data with a Savitzky-Golay filter.
	The Savitzky-Golay filter removes high frequency noise from data.
	It has the advantage of preserving the original shape and
	features of the signal better than other types of filtering
	approaches, such as moving averages techniques.
	Parameters

	y : array_like, shape (N,)

krvajal / deferred.js

Created February 7, 2017 00:13 — forked from fernandezpablo85/deferred.js

	/*
	problema de la entrevista que mencioné en el último podcast:
	https://soundcloud.com/sin-humo/entrevistas-de-trabajo-y-111mil

	la idea es crear la función 'deferred', que permita un comportamiento
	similar a lo que serían promises de javascript.

	el deferred puede 'resolverse' con un valor cualquiera, o con otro 'deferred'.

	en el segundo caso, el próximo `then` debería "esperar" también a este.
