Why your internet will never work without DNS or DNS Records?

In order to navigate to a website you need to covert http://www.mysite.com to it’s IP address. It’s also highly useful for emails.

DNS acts as phone-book of internet helping you to navigates to all the websites you love.

Different Types of DNS Records A Record

🔵 A record maps 🗺 domain to IP address (IPv4). 😎

AAAA Record

JS While Loop – Programming Foundations #08

JS while loop is your ticket to executing code neatly and repeatedly for as many times as you need. So what is while loop in JavaScript? Simply said, a while loop/statement is a loop that will execute any code blocks inside it for as long as a specified condition is met. Let’s discuss a few JavaScript while loop example below.

Types of Statements in JavaScript – Programming Foundations #06

Let’s talk about the types of statements in JavaScript. So what is a JavaScript statement? By now you know that a computer program is a series of instructions that are written to be executed by the computer. Each of these instructions is called a JavaScript statement. (more…)

JavaScript Basics – Programming Foundations #05

Let’s get started with some JavaScript basics. By now you know that JavaScript is a language that deals with web pages. Not only is it simple to learn, it’s also among the more powerful and popular languages out there today. (more…)

Syntax Programming – Programming Foundations #04

What is Syntax Programming? Every programming language comes with its own set of rules that outline the grammar and spelling within which it operates. This is called the syntax of a programming language. The syntax specifies the exact combination of symbols and characters that you can use to write code in a chosen language that will be understood by the computer.  (more…)

Compiler vs Interpreter – Programming Foundations #03

Here’s what you need to know about the compiler vs. interpreter choices you’ll need to make. By now, you already know that source code needs to be converted into machine code before it can be run by the computer. This is because at its most basic level, a computer can only understand strings of numbers that specify different operational codes. Writing code at this most basic level can get…

Microsoft Office 2019 Now Rolling Out for Mac and Windows

Microsoft Office 2019 is now here and is first being launched for commercial volume license consumers using Windows and Mac. But worry not, if you’re a general or commercial customer, you can still expect to get your hands on this brand new succession to Office 2016 over the next few weeks.  (more…)

Source Code – Programming Foundations #02

Source code is simply the list of instructions you write for the computer to execute.  It’s important to remember that source code is always written in plain text (never rich text). You can start writing code just by using a simple text editor like Notepad or TextEdit that’s already on your machine.

Source code : All you need to know

Source code is simply plain text that you use to give very…

What programming foundations will be covered here – Learn the basic concepts and elements of programming on any platform using any language. Explore the different uses of different languages and learn how to decide on the right language for a given task. . Work with common processes such as loops, variables, conditions and memory. Familiarize yourself with the flow of a program and its structure.…

Python 3 Testing & TDD – Part 02 – Python 3 TDD Some More

Python 3 Testing & TDD – Part 01

Python 3 testing is very easy. I have written unit tests in Python, Java and C++, utilizing Google Test, Google Mock, JUnit, TestNG, Mockito and Powermock (Powermock+mockito). Python is the easiest to test of them all. Python 3 being batteries included, comes with both a unit testing framework and a mocking framework. Let’s do some Test-Driven Development (TDD) with Python 3.
