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.

I wrote this four years ago, so instead use this command:

$ docker rmi $(docker images -q -f dangling=true)

I heard from GitHub Two-Factor Authentication](https://github.com/blog/1614-two-factor-authentication) nearly a couple of days ago when I was reading my RSS feed. I enabled it and couldn' push to any of my repositories anymore. Learn in this blog post how to fix it.

Two-Factor Authentication

"Is a process involving two stages to verify the identity of an entity trying to access services in a computer or in a network". Github solves this authentication with sending an SMS to a device which wants to push to their platform.

Share Counts

I have always struggled with getting all the various share buttons from Facebook, Twitter, Google Plus, Pinterest, etc to align correctly and to not look like a tacky explosion of buttons. Seeing a number of sites rolling their own share buttons with counts, for example The Next Web I decided to look into the various APIs on how to simply return the share count.

If you want to roll up all of these into a single jQuery plugin check out Sharrre

Many of these API calls and methods are undocumented, so anticipate that they will change in the future. Also, if you are planning on rolling these out across a site I would recommend creating a simple endpoint that periodically caches results from all of the APIs so that you are not overloading the services will requests.

Fetching lyrics in the command line

Objective: Print the lyrics for the current playing song.

How: We'll create a small bash script to do the fetching for us (using curl) and then we'll display it either in the terminal or in our $EDITOR

Get the current song

First we'll need to get the name of the current song and its artist:

Create patch file

git diff --no-prefix > [path file name]

Apply path file

patch -p0 < [path file name]

	import redis


	class RedisLock(object):
	"""Redis Lock implementation over redis.StrictRedis.lock.

	:param strict_client: A StrictRedis client.
	:type strict_client: redis.StrictRedis.

	# ```
	# # you should delete node_modules b/c you don't want that copied during 'ADD'
	# docker build -t thom-nic/node-bootstrap .
	# # run a shell in the container to inspect the environment (as root):
	# docker run --rm -itu root thom-nic/node-bootstrap /bin/bash
