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.

This example shows how it is possible to use a D3 sunburst visualization (partition layout) with data that describes sequences of events.

A good use case is to summarize navigation paths through a web site, as in the sample synthetic data file (visit_sequences.csv). The visualization makes it easy to understand visits that start directly on a product page (e.g. after landing there from a search engine), compared to visits where users arrive on the site's home page and navigate from there. Where a funnel lets you understand a single pre-selected path, this allows you to see all possible paths.

Features:

works with data that is in a CSV format (you don't need to pre-generate a hierarchical JSON file, unless your data file is very large)
interactive breadcrumb trail helps to emphasize the sequence, so that it is easy for a first-time user to understand what they are seeing
percentages are shown explicitly, to help overcome the distortion of the data that occurs wh

Multiple SSH Keys settings for different github account

create different public key

create different ssh key according the article Mac Set-Up Git

$ ssh-keygen -t rsa -C "your_email@youremail.com"

	yum install -y boost boost-devel
	yum install -y make gcc gcc-c++ kernel-devel python-devel
	wget https://github.com/arvidn/libtorrent/releases/download/libtorrent-1_0_10/libtorrent-rasterbar-1.0.10.tar.gz
	tar zxvf libtorrent-rasterbar-1.0.10.tar.gz
	cd libtorrent-rasterbar-1.0.10.tar.gz
	./configure --disable-debug --with-boost-libdir=/usr/lib64 --disable-encryption --enable-python-binding
	make && make install
	export LD_LIBRARY_PATH=/usr/local/lib/
	cd bindings/python
	python setup.py build

	Regular expressions and data from
	http://lh3lh3.users.sourceforge.net/reb.shtml

	Regular expressions benchmarked:
	URI ([a-zA-Z][a-zA-Z0-9])://([^ /]+)(/[^ ])?
	Email ([^ @]+)@([^ @]+)
	Date ([0-9][0-9]?)/([0-9][0-9]?)/([0-9][0-9]([0-9][0-9])?)
	URI\|Email ([a-zA-Z][a-zA-Z0-9])://([^ /]+)(/[^ ])?\|([^ @]+)@([^ @]+)
	Word .*SCSI-

	Imagine you have the following structure:

	```elixir
	iex> users = [
	john: %{name: "John", age: 27, languages: ["Erlang", "Ruby", "Elixir"]},
	mary: %{name: "Mary", age: 29, languages: ["Elixir", "F#", "Clojure"]}
	]
	```

	We have a keyword list of users where each value is a map containing the name, age and a list of programming languages each user likes. If we wanted to access the age for john, we could write:

	# Install tmux on Centos release 6.5

	# install deps
	yum install gcc kernel-devel make ncurses-devel

	# DOWNLOAD SOURCES FOR LIBEVENT AND MAKE AND INSTALL
	curl -OL https://github.com/downloads/libevent/libevent/libevent-2.0.21-stable.tar.gz
	tar -xvzf libevent-2.0.21-stable.tar.gz
	cd libevent-2.0.21-stable
	./configure --prefix=/usr/local

	You can place js source code in app/assets/javascripts, but exclude it from Sprockets. And add another dir for webpack generated files, like this:

	[config/initializers/assets.rb]

	Rails.application.config.assets.tap do \|assets\|
	assets.paths.delete_if { \|path\|
	path =~ Regexp.new('app/assets/javascripts')
	}
	assets.paths.unshift Rails.root.join('app/assets/webpack').to_s
	end

	// Use Gists to store code you would like to remember later on
	console.log(window); // log the "window" object to the console

	1. 將 ajax 的行為都定義在 actions 裡，例如 ProductionActions.js

	export function getAllProduction () {
	return (dispatch) => {
	$.ajax('xxx/products', {
	success: (data) => {
	disptach({
	type: GET_PRODUCTS
	data" data
	});
