Facebook Ads + Social Proof = Moar Sales!

At a first glance, winning ad clicks from competition seems so simple:

All you have to do is show the audience a proof that you’re better and POOF! As if by magic, they begin to ignore everyone else.

But the reality is so different, isn’t it?

Ad after ad you run struggle to make the case.

Grab the users’ attention.

And convince them to your worth.

But it’s all because your ads miss one crucial ingredient – social proof.

Social Proof

Luckily for you, that’s what I’m going to help you with today. I’m going to show you 10 examples of various social proof types advertisers use in Facebook ads.

php 7 – "HTTP_X_REQUESTED_WITH" => "XMLHttpRequest" – out of nowhere

I spent many time for this case, but i can’t understand how it arises.
So. I have legacy php application.
Now it is working on the following environment:

PHP 5.6.10-1+deb.sury.org~trusty+1 (cli) 
Zend Engine v2.6.0 with Zend OPcache v7.0.6-dev


For test i setup php-7

PHP 7.0.0RC3 (cli) 
Zend Engine v3.0.0-dev, with Zend OPcache v7.0.6-dev


So, case.
I load page first time:

After page loaded, executed several ajax requests.

After reload page, in the $_SERVER variable we have HTTP_X_REQUESTED_WITH

but as you can see in the request headers we havn’t this header.
Below you can see headers from nginx (access log)

Ajax request - - [29/Sep/2015:15:00:44 +0300] "GET /stat/notifications-count HTTP/1.1" 200 30341 "http://vm-hub.dev:8888/client" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/45.0.2454.101 Safari/537.36" "-" "no-store, no-cache, must-revalidate" "XMLHttpRequest"

and normal request - - [29/Sep/2015:15:14:32 +0300] "GET /client HTTP/1.1" 200 95434 "-" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/45.0.2454.101 Safari/537.36" "-" "no-store, no-cache, must-revalidate" "-"

IDG Contributor Network: As cloud finally enters mainstream, Accenture acquires itself into relevance

As part of the lead-up to its massive involvement at Salesforce‘s Dreamforce conference, $30 billion global professional services company Accenture announced that it was acquiring Cloud Sherpas, one of the larger, more successful cloud solution providers. Cloud Sherpas was only founded a few years ago. Indeed, I remember having a conversation with the founders at Google IO back in 2008, only a year after the company’s founding. Back then it was a tiny team, and its somewhat nebulous business model was to help companies with their Google Apps deployments.

How to make your own bootable OS X 10.11 El Capitan USB install drive

Enlarge / Even in the download-only era, it’s easy to make yourself offline OS X install media. (credit: Andrew Cunningham)

It was 2009 when Apple last released a new operating system on physical media. Things have proceeded remarkably smoothly since version 10.7 switched to download-only installers, but there are still good reasons to want an old, reliable USB stick. For instance, if you find yourself doing multiple installs, a USB drive may be faster than multiple downloads (especially if you use a USB 3.0 drive).
