In August 2007 a hacker found a way to expose the PHP source code on facebook.com. He retrieved two files and then emailed them to me, and I wrote about the issue:

It became a big deal:

The two files are index.php (the homepage) and search.php (the search page)

Make it real

Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discuss around concrete examples, not hand-waving abstractions. Don't say you did something, provide a URL that proves it.

Ship it

Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.

Do it with style

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

Full blog post can be found here: http://pnommensen.com/2014/09/07/high-performance-ghost-configuration-with-nginx/

Ghost is an open source platform for blogging founded by John O'Nolan and Hannah Wolfe. It's a node.js application and therefore works great in conjunction with nginx. This guide will will help you create a high performance nginx virtual host configuration for Ghost.

"Don't use #nodejs for static content" - @trevnorris. If #nginx isn't sitting in front of your node server, you're probably doing it wrong.

The node.js application runs on a port on your server

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics

elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent

Guide on how to create and set up your Django project with webpack, npm and ReactJS :)

Hopefully this will answer "How do I setup or start a Django project?" I was trying to set up my own website, and there was a lot to read, learn and digest! Therefore, I put this together which is a collection of all the guides/blog posts/articles that I found the most useful. At the end of this, you will have your barebones Django app configured and ready to start building :)

NOTE: This guide was built using Django 1.9.5, NodeJS 4+ with NPM 3+

A curated list of AWS resources to prepare for the AWS Certifications

A curated list of awesome AWS resources you need to prepare for the all 5 AWS Certifications. This gist will include: open source repos, blogs & blogposts, ebooks, PDF, whitepapers, video courses, free lecture, slides, sample test and many other resources.

	#!/bin/bash

	NAME="hello_app" # Name of the application
	DJANGODIR=/webapps/hello_django/hello # Django project directory
	SOCKFILE=/webapps/hello_django/run/gunicorn.sock # we will communicte using this unix socket
	USER=hello # the user to run as
	GROUP=webapps # the group to run as
	NUM_WORKERS=3 # how many worker processes should Gunicorn spawn
	DJANGO_SETTINGS_MODULE=hello.settings # which settings file should Django use
	DJANGO_WSGI_MODULE=hello.wsgi # WSGI module name

	Apache:
	- Activated 'KeepAlive' connections
	- Lowered keep alive timeout from 15 seconds to 2 seconds
	- Increased the number of minimum workers from 8 to 16
	- Activated server status page (/server-status)

	APC (Alternative PHP Cache):
	- Set cache size to 256MB (ideal for SugarCRM workload)

	Memcache:

	/* bling.js */
	window.$ = document.querySelector.bind(document);
	window.$$ = document.querySelectorAll.bind(document);
	Node.prototype.on = window.on = function(name, fn) { this.addEventListener(name, fn); };
	NodeList.prototype.__proto__ = Array.prototype;
	NodeList.prototype.on = function(name, fn) { this.forEach((elem) => elem.on(name, fn)); };
