    For the Application frameworks module, we were assigned a project of developing a 'Conference Management Tool'. It is to be named as 'International Conference on Application Frameworks' (ICAF). When developing this tool, there should be a login and user levels should be maintained as admin, editor, reviewer and user.   In this tool there should be options for researchers to upload their research papers and workshop presenters to upload their presentations. I was assigned with the development of the component of uploading and managing research papers. The templates for the research papers would be available separately in the application. For this project we were asked to build the front end using react and when using react we were asked to build from scratch and not to use npx create-react-app. This requirement led me to research on the difference of creating and maintaining a react application in these two different ways. Both ways may have their own advantages and

  React is a very popular front end java-script library which is created and maintained by Facebook. It can be used to build responsive single page applications. There are several ways to initiate a react project. Either you can build from scratch or use a tool-chain recommended by the react team. Building from scratch To build a react project from scratch you have to initiate a node project by issuing the command 'npm init'. Then you can issue the command 'npm install react-router-dom' to install the dependencies related to react. Then you have to add 2 files, index.html and index.js. Instead of index.js index.jsx also can be used. These files can be added to the root directory itself. When building an application from scratch there is no restrictions as to the directory structure. But it is always a good practice to maintain proper directory structure. When building from scratch you can also use tools like webpack or parcel for bundling. Building using create-react-ap

      Introduction Ubuntu is a Linux distribution published by the canonical team. The term ‘Ubuntu’ is an ancient African word meaning ‘humanity to others'. Ubuntu is a freely available desktop operating system that is easy to use. There are other versions of Ubuntu that are targeted for Servers, IoT and Cloud as well. In this article we are going to focus on installing Ubuntu desktop on a personal machine. Why Ubuntu? There can be several reasons for a person to use Ubuntu as their Operating System on the machine they use. The first obvious point is that is free to use. Therefore, some people may like to use this for their computational tasks. Some people can have use cases that will require a Linux system (or a UNIX like OS) such as programming in C or android platform development (which can be harder or impossible to perform on a Windows environment). For those people, a Linux distribution will be a good option (Since other UNIX like Systems can be cost prohibit

At present, many people are connected to the internet and actively using web browsers. So it will be interesting to have a look at JavaScript engines which make these browsers the kind of software they are. What is a JavaScript engine? A java script engine is a program that is mostly run in browsers which executes JavaScript codes. Most of the time, these engines use C++. These are also known as ECMA script engines since ECMA script is the standard specification for java script. First java script engines were interpreters. First java script engine was created in 1995, by Brendan Eich for the Netscape Navigator Browser. This evolved into spidermonkey engine which is used in Firefox browser. Today, most of the java script engines are developed and distributed by web browser vendors like Mozilla and google. Java script engines are run in browsers via the Document Object Model together with the rendering engines. Today java script engines are not only used for browsers, but for other fr

As a person who is enthusiastic about programming and developing, I constantly look for new technologies and trends that emerge. Flutter came under my radar a couple of years ago when I was researching about mobile application development.  At that moment, my mobile development skills were limited, but nevertheless, I decided to give it a try. It interested me as it promised to help the developer make an application that would run on android, iOS, an even the web with one code base. I completed one or two tutorials offered by the flutter developer site itself but as time went on due to other areas of my studies I had to focus on, flutter slowly slipped away from me. Fast forward to today, and I have received a fair amount of beginner experience on native android development and I decided to try out flutter again. Although it offers many options, I mainly focused on mobile development. What is flutter?   Flutter is a UI toolkit offered by google intended to be used to develop applic
