The Twelve-Factor App Methodology for building a successful SaaS Applications

Software as a Service (SaaS) is a software licensing and delivery model. Here, the service provider hosts applications and makes them available to customers over the Internet. Salesforce.com is a well-known example of software as a service.

What is Level of Assurance?

An entity can be a person, a server a or a client etc. We need secure and standard ways to do entity authentication.

To fulfil that requirement International Standard defines a framework for managing entity authentication assurance in a given context. Which is named as  Entity Authentication Assurance  Framework (EAAF). It specifies four Levels of Assurance(LoA). 

Fundamental of React

React is a declarative, efficient, and flexible JavaScript library for building user interfaces. It lets you compose complex UIs from small and isolated pieces of code called “components”.  Followings are some fundamentals that you need to know when you work on React.

An Introduction to React using Flux Architecture

Flux is developed by Facebook as an application architecture for UI  implementation. React is a JavaScript library which is used to build user interfaces.  So Facebook use Flux architecture when they implementing user interfaces with React.

Applications which are implemented in React using flux architecture have four major parts. These are independent nodes with distinct inputs and outputs.

•    Actions
•    Dispatcher
•    Stores        
•  Controller Views

Unidirectional Data Flow through major parts

What is Natural Language Processing and how does it works ?

In 1950 Alan Mathison Turing (often called as the father of modern computing) published his famous paper titled “Computing Machinery and Intelligence”. That was a seminal paper on the topic of artificial intelligence. In here Alan introduced a game called "The Imitation Game” and he proposed a variation of this game that involves the computer.

Then Alan Turing expressed an opinion that if a machine could have a conversation with a human and trick the human into thinking the machine was a person itself, then it was artificially intelligent. That was named as Turing test and became the first step to the birth of artificial intelligence.

What is Quantum Computing?

Today's computers which are named as classical computers, work by manipulating sequence of bits. A bit is the smallest unit of data in a classical computer which has single binary value, either 0 or 1. A quantum computer is worked by manipulating sequence of qubits. But a qubit is not limited to two values. A single qubit can represent 1 or 0 or any quantum superposition of 0 and 1.

What is Microservices Architecture?

Since everything changes in the digital world, software applications developing techniques are also changing day by day. Microservices Architecture is a software development method which is a variant of the service-oriented architecture (SOA) architectural style.

What is Docker?

“ It works on your computer. So why is it not working on my computer? ”

 This is a familiar problem with all computer users. Is there a way to solve this problem? Yes. Have you heard about Docker? Docker is the world’s leading software container platform which supports to eliminate this problem. Let’s get to know about Docker.

What is failure detection and failure masking in distributed system ?

A distributed system

Is a model in which components located on networked computers communicate and coordinate their actions by passing messages. The components interact with each other in order to achieve a common goal. 

Let's create 8 bit LED binary counter

Here, I am going to discuss how to create 8 bit LED binary counter using Arduino micro controller board . This binary counter  displays  decimal numbers from 0 to 255 in 8 bit binary format using 8 LEDs, where as 1 is represented by lighting only left most  (2)  LED.Number  representation will be increased from 0 to 255 automatically .

Following figure shows several lighting patterns according to the decimal value from 0 to 7.
