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.

Tabs and Windows

Function	Shortcut
New Tab	`⌘` + `T`
Close Tab or Window	`⌘` + `W` (same as many mac apps)
Go to Tab	`⌘` + `Number Key` (ie: `⌘2` is 2nd tab)
Go to Split Pane by Direction	`⌘` + `Option` + `Arrow Key`
Cycle iTerm Windows	`⌘` + `backtick` (true of all mac apps and works with desktops/mission control)

Using Git to Manage a Live Web Site

Overview

As a freelancer, I build a lot of web sites. That's a lot of code changes to track. Thankfully, a Git-enabled workflow with proper branching makes short work of project tracking. I can easily see development features in branches as well as a snapshot of the sites' production code. A nice addition to that workflow is that ability to use Git to push updates to any of the various sites I work on while committing changes.

	/* Polyfill indexOf. */
	var indexOf;

	if (typeof Array.prototype.indexOf === 'function') {
	indexOf = function (haystack, needle) {
	return haystack.indexOf(needle);
	};
	} else {
	indexOf = function (haystack, needle) {
	var i = 0, length = haystack.length, idx = -1, found = false;

-# delete local tag '12345'
-git tag -d 12345
-# delete remote tag '12345' (eg, GitHub version too)
-git push origin :refs/tags/12345
-# alternative approach
-git push --delete origin tagName
-git tag -d tagName

	function encodeUTF8(s) {
	var i = 0, bytes = new Uint8Array(s.length * 4);
	for (var ci = 0; ci != s.length; ci++) {
	var c = s.charCodeAt(ci);
	if (c < 128) {
	bytes[i++] = c;
	continue;


	var net = require('net');

	// creates the server
	var server = net.createServer();

	//emitted when server closes ...not emitted until all connections closes.
	server.on('close',function(){
	console.log('Server closed !');
	});
