    How To Work With Multiple Github Accounts on a single Machine

Let suppose I have two github accounts, https://github.com/rahul-office and https://github.com/rahul-personal. Now i want to setup my mac to easily talk to both the github accounts.

NOTE: This logic can be extended to more than two accounts also. :)

The setup can be done in 5 easy steps:
Steps:


Step 1 : Create SSH keys for all accounts
Step 2 : Add SSH keys to SSH Agent

Steps to install and run PostgreSQL 9.2 using Homebrew (Mac OS X)
(if you aren't using version 9.1.5, change line 6 with the correct version)

1. launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.postgresql.plist
2. mv /usr/local/var/postgres /usr/local/var/postgres91
3. brew update
4. brew upgrade postgresql
5. initdb /usr/local/var/postgres -E utf8
6. pg_upgrade -b /usr/local/Cellar/postgresql/9.1.5/bin -B /usr/local/Cellar/postgresql/9.2.0/bin -d /usr/local/var/postgres91 -D /usr/local/var/postgres
7. cp /usr/local/Cellar/postgresql/9.2.0/homebrew.mxcl.postgresql.plist ~/Library/LaunchAgents/

## Enhance.js
import { Component } from "React";

export var Enhance = ComposedComponent => class extends Component {
  constructor() {
    this.state = { data: null };
  }
  componentDidMount() {
    this.setState({ data: 'Hello' });
  }
  render() {

## person.ajs
// Alternative JavaScript Syntax

Person = :(name, address) { @name!, @address! }
Person::inspect = :{ <: "{@name} lives at {@address}" }

                Octave - find the min (or max) value of a Matrix, and the associated row and column
              
          
    Whilst working through the many (Octave) coding assignment from Andrew Ng's Stanford Machine Learning course, a common problem that I have to solve revolves around this:
Given a Matrix A with m rows, and n columns find the mininum (or maximum) value and the associated row and column number
This article summarises my solution to this problem (which, hopefully this will also come in hadny to you!). Note that Octave index start from 1 (instead of 0).
Sample Matrix

Say we have a Matrix A that look like this:

    JSX Spread Attributes

If you know all the properties that you want to place on a component a head of time, it is easy to use JSX:
  var component = <Component foo={x} bar={y} />;
