Sample Page

This is an example page. It’s different from a blog post because it will stay in one place and will show up in your site navigation (in most themes). Most people start with an About page that introduces them to potential site visitors. It might say something like this:
Hi there! I’m a bike messenger by day, aspiring actor by night, and this is my blog. I live in Los Angeles, have a great dog named Jack, and I like piña coladas.

InstaLV – Live Stream To Instagram From Computer

Instagram allows you to livestream from the phone only. And that too from the camera which means you can’t add extra effects, overlays or cool stuff like that.
If you could livestream from the computer, you can customize the livestream video as you like. Similar to livestreams on YouTube or Twitch.
I was bored and was thinking of cool projects to do. I just got into Instagram and was checking it out.

Loading Bar until page loads completely using Javascript

This tutorial was requested by Sumit. In this tutorial I’m going to tell how to put up a loading screen until the page has loaded completely.
DEMO Here is the screenshot of loading screen :

The loading bar will fade out when loading is completed.
This code will work for all sites including Blogger Blogs, WordPress Blogs except Dynamic Views Template of **Blogger **(because it uses ajax loading). You can change the image if you want.

Cross Origin Communication – window.postMessage

The Window.postMessage helps to make scripts talk over different domain connections. When you call a function on an external iframe from the parent window, Javascript won’t allow it.
That’s because of the Cross Domain Policy that makes this not possible. But it’s possible since Javascript introduced postMessage function.
Suppose you want to call a function on an cross domain iframe with id monu. Let the function be subins(). Here’s how to do it using postMessage technic.

Better Google Chrome History Page

As you know, Google Chrome‘s Browser History is not efficient. It’s history is not like any other browsers. I think they made the History page in a hurry. If we want to search for a page we visited before, we won’t get it by searching on History page. That’s the main problem.
This problem was solved when a lot of users created an alternate History Page extension on Chrome Webstore.
In this post I’m gonna tell the most used History Alternate Extension.

Create MySQL Injection free Secure Login System in PHP

There were a lot of people who created tutorials to create a PHP Login System. But they were all vulnerable to MySQL Injection. In this post I’m going to demonstrate a login system free of this vulnerability. It is very secure. There are mysqli and PDO in PHP to escape these injections. We are going to use **PDO ( PHP Data Object **).
Download Demo UPDATE – logSys There is a new, free, better Advanced Login System which you can check out here.

Setting Iframe height to its content height using Javascript

While loading an iframe on page the most difficult thing is to set it’s height to the height of the content of the iframe. I looked around the web and got the code. This is pure Javascript, doesn’t contain jQuery or any other libraries. Set these functions :
function getDocHeight(doc) {
    doc = doc || document;
    var body = doc.body, html = doc.documentElement;
    var height = Math.

Generating Random String in PHP

In PHP you can generate random number by using rand function, but there is no specific function to generate a random text or string. In this post I’m going to show the function that will generate a random string of length mentioned.
Here is the function:
function rand_string($length) { $str=””; $chars = “subinsblogabcdefghijklmanopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789”; $size = strlen($chars); for($i = 0;$i < $length;$i++) { $str .= $chars[rand(0,$size-1)]; } return $str; } Usage To generate a random string use rand_string() function with the parameter of length of the to be generated string.
