The introduction to Reactive Programming you've been missing

This tutorial as a series of videos

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

ANNOUNCEMENT

I have moved this over to the Tech Interview Cheat Sheet Repo and has been expanded and even has code challenges you can run and practice against!

Introduction

Learn REST API with Python script, slides : http://www.slideshare.net/larrycai/learn-rest-apiwithpython

REST/JSON is perfect match to fetch web data, and python requests module

How not to `rm` yourself

Copied from https://github.com/sindresorhus/guides/blob/master/how-not-to-rm-yourself.md

The rm command is inherently dangerous and should not be used directly. It can at worst let you accidentally remove everything. Here's how you can protect you from yourself.

	Thanks again for taking the time to speak with me and for sending me your information. I'm excited to tell you that we would like to move forward in the process!

	One of our coordinators will be emailing you within the next week from an @google.com domain with the date and time of your phone interview. In the meantime, I've included some preparation materials (below.)

	Please note this will be a technical interview that will last for approximately 45 minutes. Google takes an academic approach to the interviewing process. This means that we are interested in your thought process, your approach to problem solving as well as your coding abilities. You may be asked questions that relate to technical knowledge, algorithms, coding, performance, how to test solutions, and perhaps your interest in Google products. The best advice that I can give you is to treat the interview like a conversation, talk through the problems, and please feel free to ask the interviewer if you are not clear with any of the questio

	# Import files under folder name fawn
	# It is very important to include the option (full.names=TRUE). It it is not included
	# then you will get the error something like
	# "Error in file(file, "rt") : cannot open the connection In addition: Warning message:
	#In file(file, "rt") : cannot open file 'FAWN_2002.csv': No such file or directory

	mydata=ldply(list.files(path="data/fawn/",pattern="csv",full.names=TRUE),function(filename) {
	dum=read.csv(filename)
	dum$filename=filename
	return(dum)
