7 Devops tools which you should know to create a productive devops culture

Let me state it in start without any introduction. Devops is a culture of practices. It is not a tool. In fact, it is a set of processes for which we use different type of tools, so we can create the culture we want to follow in our organisation or project life cycle. There are lots of open source or proprietary tools to service our devops strategies.

Devops is a combination of rituals as well as tools to do those rituals.…

Is a knowledge of Hadoop required to learn Spark?

You need to understand some basic differences between hadoop and spark.

One of the major difference is file system. Hadoop has HDFS while spark does not have any native file system associated with it.

So, you can run spark without hadoop in theory., but you need something to handle data. HDFS is one of the best choice for this task, in that case, you need to know the basic of Hadoop to get good results from Spark.…

Why do we use a token concept in PHP?

Question is not specific to PHP only, it is generic for Web development, language will not matter.

PHP has session tokens through which server will identify the session id of a specific user, (this is similar to many other languages). These tokens can be sent via cookies or via embedding in urls. In terms CSRF attacks, urls one are much better but these also expose many other security issues as token is embedded automatically (if you did not change your ini settings) to urls.…

Cloud Computing Security

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

 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.

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?…
