What is the difference between this & this(), super & super()
Jul 30th
Well the topic is a basic in OOP, when I first learned my first OO language (C++ back in 2004), I have learned the basic. Few days ago some one asked the question, suddenly I become confused, so I made a quick research, and decided to post 
this and super both are object. this() and super() both are constructors.
this is the object of current class.
this() is the constructor of current class.
super is the object of parent class.
super() is the constructor of parent class.
Example (in java) please check out this nice example provided in this link
I hope this will save someone’s day
How to generate getter/setter in PHP easily
Jul 14th
For one of my current project I need to write getter/setter functions for 20+ variables. You know, how annoying it is! Well, I can use magic quotes, but I don’t like it. More over getter setter will help you later to use the class when your IDE (in my case Netbeans) supports auto complete suggestion. Though all Java development environments allow to generate getter and setter code automatically.
Then I started coding a php script for generating getter/setter for supplied variables, but I was lucky as suddenly I thought “why don’t I look for something like this online”
And here is the link I got, its quite good. http://www.icurtain.co.uk/getset.php, It saved my time.
How to enable Apache HTTP Authentication using PHP
Nov 11th
The easiest way to password-protect a site is to use HTTP Authentication, where if a browser’s request for a protected page is not accompanied by the correct username and password, the Web server replies with an HTTP 401 error – which means “Unauthorized Access” – and an invitation for the browser to re-submit the request with a proper username and password. From the user’s point of view, most of this dialogue is hidden. Following that first failed request, the browser prompts the user (in a dialog box) for a username and password, and then re-submits the request, this time with the authentication information attached. Assuming the username/password combo is on the list of allowed users, the Web server then sends the page requested. The Web browser will likewise continue to send that username/password with all subsequent requests.

Do you need to write your first thesis paper or do you want your publication published in a famous journal?

Definitely a annoying, time consuming task, So I have decided to share it
I am going to describe it step by step, please follow these steps as described, its important. I am assuming you have Windows XP or later versions and you have administrative privilege.
How to overcome download time limit
May 25th
Some file storage sites give you a download link which use to expire after a definite time , like 1 hour or 24 hour. MiHD.net is one like them. They allow you to download files hosted on their server without any limitations, but the download link will be functional for 6 hours or other certain time. Not only these file hosting servers, often many sites from where you can download movie or songs, impose this kind of time limitation to balancing load.
But surely you can overcome this limitation.

Have you checked this? write www.google.com and google.com in your browser’s address bar, then hit Enter. Both will work. same as true for Yahoo!, WordPress.com and other leading sites. Again there are some sites which won’t work without ‘www‘, like www.buet.ac.bd will work but buet.ac.bd won’t work.
So what’s the reason behind this?
How to verify an ISO image in linux before burning
May 17th
There is no nice or 100% effective fast way to verify an ISO image of any OS [normally *INX based OS] without installing. But there are several ways one can test the ISO image. If the test(s) are successful, there is a high (to me which is almost 100% ) probability, that the ISO is perfect to be burned in a CD or DVD which one is desirable.
