Hey Everyone,

So I was planning to write some getting started guides for some trending technologies and frameworks for web applications development.

But, I was totally confused with one thing and that was the Operating System. Because, I don’t want to write getting started guides for all different OS that we commonly use. And this one confusion led me to Docker. As many of you might not know about Docker or might haven’t used it before. Therefore, I decided to help you get started with Docker with a minimum level introduction and installation guide.

So Let’s begin!!

What is Docker

In a nutshell…

Why Google’s ML Kit?

Although, I have worked with Zxing barcode library in past for…

What is Firebase

Firebase is basically a mobile and web application development platform that help developers and companies to quickly integrate some very exciting as well as interesting features in their applications.

Although it was initially introduced and developed by Firebase Inc as a company itself in 2011 as a separate platform. And at that time it was just used for real time data synchronization and hosting in cloud by different mobile applications, including Android and iOS. …

Sass (Syntactically Awesome Style-sheets) is basically a scripting language that is compiled or interpreted as CSS (Cascading Style-sheets). As per official Sass website it is a CSS extension language or CSS with super powers.
