Migration from SVN to Git

Migration is not always easy. However, git-svn is a quite useful tool to do the job.

To do the job right, this post from stackoverflow is tremendously helpful in my entire process.

I wrote the m.py to automate the entire process.

###Pre-requisites:

Any version of Windows newer than XP or Server 2003.
A good text editor. I recommend Sublime Text 2.
If you use Sublime Text, you can get very helpful syntax highlighting while editing Apache Conf files by installing Package Control. Once fully installed and SublimeText is restarted, CTRL+SHIFT+P -> Install Package -> ApachConf (enter).
This assumes you have a public domain pointing to your WAN IP. Figure that out from whatismyip.com. If you purchase a domain and use a CNAME or A-record, it can take some time for the DNS changes to propagate. I've seen anywhere from 15 mins to several hours.
Within your router, you must forward port 80 to your LAN IP which hosts Apache.

This is a list of implementation and usage of popular data structure with JavaScript.

Currently include:

	const Observable = Rx.Observable;

	const toggleButton = document.querySelector('#toggle');

	const toggleClick$ = Observable.fromEvent(toggleButton, 'click');
	const interval$ = Observable.interval(1000);

	const toggle$ = toggleClick$
	.startWith(false)
	.scan((acc, curr)=> !acc); //toggles true/false

	import path from 'path';
	import webpack from 'webpack';

	module.exports = {
	devtool: 'cheap-module-eval-source-map',
	entry: [
	'webpack-hot-middleware/client',
	'./index'
	],
	output: {

	var _ = require('underscore');

	module.exports = function(Customer) {
	Customer.getRolesById = function (id, cb) {
	Customer.getApp(function (err, app) {
	if (err) throw err;
	var RoleMapping = app.models.RoleMapping;
	var Role = app.models.Role;
	RoleMapping.find({ where : { principalId: id }}, function (err, roleMappings) {
	var roleIds = _.uniq(roleMappings

	* Question - Given an image represented by an N x N matrix, where
	* each pixel in the image is 4 bytes, write a method to rotate the
	* image by 90 degress. Can you do this in place?
	*
	* rotateCopy() method is a brute force method to transpose one item
	* at a time and return a new array. It is very slow. The time
	* complexity is O(N^2), and it take as N^2 * [0-2^32) bits of memory.
	*
	* rotate() method performs a cyclic swap on the edges on each layer.
