What the application does is to programatically convert PHP source code into C++ and compile it with g++.

According to senior engineer Haiping Zhao, Hiphop has now been deployed to 90% of the Facebook traffic, six months after deployment.

In a nutshell, this is what is happening. Google is getting posts and status updates from many networking sites and allowing them to be shown in the search results. How are they gonna do that? I got my answer within a few days.

Facebook had a change in their privacy settings. The time that you log into facebook, you will be notified of the privacy settings page and would suggest you that you change your settings to their recommended one – one that is seen by practically everyone.

Now, I am no privacy freak. Far from that. What I am concerned about is that by allowing your profile to be shown to all, a person will risk being used or taken advantage of by unscrupulous individuals in the net.

I’ve had my cellphone number been sent text messages by people I do not know about some nice deal which was clearly a scam. I’ve had a rise in spam messages when I placed my email in a post or comment in a blog.

Having said that, I strongly agree with Bruce Schneier, a well known computer security specialist, that:

For if we are observed in all matters, we are constantly under threat of correction, judgment, criticism, even plagiarism of our own uniqueness. We become children, fettered under watchful eyes, constantly fearful that — either now or in the uncertain future — patterns we leave behind will be brought back to implicate us, by whatever authority has now become focused upon our once-private and innocent acts. We lose our individuality, because everything we do is observable and recordable.

in his blog as a rebuttal to Eric Schmitt, CEO of Google, who said a dangerous statement to Maria Bartiromo during CNBC’s big Google special, that “If you have something that you don’t want anyone to know, maybe you shouldn’t be doing it in the first place.”

Think about it. You don’t hide things from people you don’t know because you did something bad. It is more likely that you hide things from people you are not likely to trust because they would like to do bad things to you.

What makes facebook interesting are its applications; which are mostly user created, and add life to the social networking site.

Here’s how to submit a facebook application to the net:

1. Join as a facebook developer, and on the http://www.facebook.com/developers/ url, click on the Set up new application button

2. On the Create App page, type in the name of your application

3. Take note of the API Key and Secret; you’ll need these later. Fill up the necessary items in the Basic Page.

4. Enter the canvas url (where your application will reside in apps.facebook.com), and the content url where your application is hosted.

5. Press Save, and you’re off to start a brave new world of creating a Facebook Application!

The simplest start for a facebook application looks like this:

require_once 'php/facebook.php';
require_once 'config.php';

$facebook = new Facebook($api_key, $secret);
$user_id = $facebook->require_login();

echo “Hello, $user_id!”;

facebook.php is the facebook php client which you can download in the developers site. You can learn more about the api in the http://wiki.developers.facebook.com/ site.

Have fun!
