Today we will be setting up Security Onion OS in a 3 nodes cluster, we will be using Virtual Box.

3 machines have been created in VirtualBox.

1. The Machines

the 3 nodes in VBox

The 3 nodes share the same specs (we did not use the required minimum specs): 1 GB RAM, 100GB hard drive.

SO-Node1: Manager Node

SO-Node2: Forward Node

SO-Node3: Search Node

2. Download

We have followed the step by step tutorial in the security onion GitHub account for downloading and verifying the operating system, the instructions can be found…


The app that will be created in this tutorial

Hey guys, today we will be building a roman numerals converter app in Javascript, you can check out the app in action here.

The app will convert Roman numerals into Arabic numerals and on the other hand Arabic numerals into Roman numerals. For simplicity purposes, the app will convert numbers between 1 and 3999.

For this tutorial, we are going to have three files index.html, style.css, and app.js. Let us dive right into coding.

1. The HTML file

index.html

That is a very simple HTML code. There we have the main div that contains all the elements. An h1 element, and the two input…


To-Do List app developed in the tutorial

Today we will be building a very simple To-Do List app using pure javascript, you can check it out live here. A good practice exercise for people who have learned DOM manipulation, worry not if you do not know DOM manipulation. I have written this tutorial to teach the basics of DOM manipulation.

The app will be able to add a new task, tick a task, remove a task and, clear the task board. We will need to create three files: index.html, style.css, and app.js.

Let us then get into coding.

1. The HTML file

index.html

That is it for the HTML file, you…


So you have learned variables, selection structures, and loops. Now it is time to learn about DOM manipulation and to start doing some cool JavaScript projects.

In this tutorial, we will learn how to manipulate the DOM with vanilla JavaScript. With no further ado, let’s jump right into it.

1. First things first

Before we dive into coding, let’s learn what the Dom really is:

The Document Object Model (DOM) is a programming interface for HTML and XML documents. It represents the page so that programs can change the document structure, style, and content. The DOM represents the document as nodes and objects. That…
