What is the best Linux software to monitor web traffic on router?

What is the best Linux software to monitor web traffic on router?

,, May 10, 2016  No Comments

 am assuming that you want to log and monitor the traffic which is passing through a hardware router.

Your question seems incomplete to me because at router level, it is difficult to decide if data which is being transferred is for web or something else.

You can treat all TCP/IP data transfer as web data or to be more precise, you can treat data passing through port 80 as web data. ( As port 80 is default http protocol), but technically speaking http server can listen on any available port.…

How to handle checkout when we are selling unique products?

Checkout process for unique product has to be handled in different way than products which are available in quantities. Products with one quantity are unique product. Paintings, concert tickets, hotel rooms, flight tickets ( when you choose a specific seat) are unique products. Old household items are also unique items.

We have two types of process for processing any purchase. In first type, we can do cart based checkout where a user usually add more than one product to their cart.…

Your projects are not your real baby, you may need to dispose them

Your projects are not your real baby, you may need to dispose them

“This project is my baby, I don’t want to see it perform badly, I will give everything to protect it”, Does this sentence sound familiar to you? You may have heard it from your colleague or may have said it yourself.

In my view, ‘Like my baby’ is a metaphor which is over used and abused by many persons. What you will do when you found a really bad architecture based application whose programmers are just treating it like a baby?…

What are some limitations of PHP?

What are some limitations of PHP?

, August 12, 2013  No Comments

Recently I answered a question on quora. I am reproducing it here again.

In my view question is not complete and does not provide context which has to be evaluated to answer.

So I am writing this answer based on two assumptions.

First of all I am assuming that questioner is evaluating few programming languages and wants to make a decision which language to use or learn?

One of the major feature of PHP is also its biggest limitation. It is loose type and does automatic data type conversion in most of the situations.…

Drupal vs Zend : which one should be used for application development?

,,,, March 4, 2013  No Comments

“You have done that specific site in Zend, don’t you think our application is also suitable for Zend instead of Drupal”, I just got this email from a prospective client.

This question has been asked to me many times. I am a big fan of Drupal as well Zend, so this question always put me in my difficult zone. As I know both, I really can not take a stand against any one of them. Technically speaking, both are capable of handing any kind of project, although both have their pros and cons.…

Why randomization is a difficult algorithm to implement?

,, March 4, 2013  No Comments

If you are doing programming, You must have used random numbers. They are useful in many situations when you want to give some randomization to your program output like lottery draw, random banners generation, random user display etc.

In PHP rand function is being used to generate random numbers, but is it really random number generator? Take a look at the following code.

< ?php for($i=0;$1i<50;$i++) { print rand(); } ?>

What this function will do? If you are thinking that it will produce 50 random numbers, you just need to run this code.…

Web programming is not only about how you develop your applications, its also about how you deploy your application or website.Although control panels are being provided by almost every shared hosting company using which we can easily deploy our applications but as soon as application grows in terms of size or scalability we need to put that on virtual dedicated or dedicated or in a cloud server like amazon EC2 .

Linux system administration is specialized field in itself but if as a programmer you also know how to handle some common tasks you can get good turn around as well as can optimize your application for performance.…

Bigdata is the word which is being used very often but yet to be defined properly. How much data can be classified as big data? Does big data only means big in size or big in complexity or both? If hard disks can be clubbed together to store very very large amount of data then why whole world has become so obsessed with big data? Is it something different from traditional DBMS?

There are many questions which may come to the mind of a person who is starting his journey with big data.…

Algorithms are defined sets of instructions to solve a problem or achieve something. Almost every process in computer world can be classified as an algorithm, still it is most difficult part of computer science for many learners.

Algorithms are necessary to make your programs intelligent and efficient. They can make your program rock and it can stand out in front of competition. You need to be good at analysis, understanding and draw abstraction to get good hold on this subject.

In this post I am trying to compile a list of algorithms which every program should know.…
