Praveena Thavarajah — Sun, 21 Aug 2022 04:33:39 +0000

My new blog about “Sadness VS Depression”. I hope it will be useful to differentiate those two words.

People who have never dealt with depression think it’s just being sad or being in a bad mood. That’s not what depression is for me; it’s falling into a state of greyness and numbness. — Dan Reynolds

We hear about sadness and depression regularly but mostly during and after the pandemic. Most of us think these two words are some but sadness and depression have two different meanings.

What are SOLID Principles? Explained with OOP Concepts.

Praveena Thavarajah — Sat, 06 Nov 2021 09:12:32 +0000

Software developers implement codes to meet the users’ requirements and satisfy the clients. Some principles have to follow by software developers to enhance their code writing skills.

The SOLID principles have considerable responsibility to guide the software developers, to make the software design by improving the code quality.

An American software engineer named Robert C.Martin created this principle.

Solid principles have five(5) principles. The name is created by considering the first five letters from each principle.

The five principles are,
S — Single Responsibility Principle
O — Open Closed Principle.
L — Liskov Substitution Principle.
I — Interface Segregation Principle.
D — Dependency Inversion Principle.

Let us have a look at each of the principles. Read more at https://praveena-thavarajah.blogspot.com/2021/11/what-are-solid-principles-oop-concepts.html.

How to include .scss file into HTML?

Praveena Thavarajah — Thu, 23 Sep 2021 06:18:38 +0000

I was finding a solution from yesterday to link a file to an HTML file.
Finally, I found the solution to the problem.

I share the solution with you all and hope it will be informative to one of you.

If there is a separate .scss file as style.scss How to link .scss file in .html file?

Problem:

Initially, I tried to link in the .html file as mentioned below,

The above method did not work. Later I understood that It is impossible to link a .scss or saas file inside the HTML file.

Solution:

I use VS Code as IDEA for coding purposes.
VS Code has an extension named Live SAAS Compiler.

Install the extension and then link the .scss link as mentioned below,

(make sure to change the style.scss into style.css inside the link tag but not in the original file).

Then click on the Watch Sass button in the footer of the VS Code IDEA.

At last, you can view the design using the browser.

Thank you so much for reading the post. I hope you got to learn a new tip.

What Are Microservices?

Praveena Thavarajah — Sat, 07 Aug 2021 09:59:53 +0000

The software architecture organizes the software structures (components, interactions of the components with each other, environment, principles used to design the software product).

A software architect is a person who handles design architecture for a particular application. The software architect’s functions are, 👇

Identify the system’s structure.
Identify the use-cases relevant to different scenarios.
Organize the user requirements (functional and non-functional)

There are many software architectures. When developing an application, the most suitable architecture has to select. Fault selection of architecture leads to the failure of an application. So the time and allocated budget will become useless.

Micro-services

Micro-services is an architecture, which has Service Oriented Architecture (SOA). SOA has an application scope. It is suitable for a large-scale application. The micro-service architecture uses to develop an application and structure it as a group of services.

This architecture has five core components are, 👇

Micro-service
Container
Service mesh
Service discovery
API gateway.

When to use Micro-services? 💁

7 Programming Tips For Developers | Beginners

Praveena Thavarajah — Sun, 11 Jul 2021 11:17:38 +0000

What should you consider when coding for a project?

Code everyday.
```
            "Practice makes perfect."
```

Practicing coding day by day will eliminates the fear on coding. It helps to improve our coding skills, and build the confidence step by step. Do not get demotivated at the initial stages.

During the initial stages of coding it takes more time to implement a function, takes many days to solve an error. It is totally fine. Every developer faced the same issue at the beginning, therefore you are not the first person to face this problem, and get stressed. Everything will be ok when you start coding continuously.

When you once start coding, you identify the mistakes, and solve the problem by searching through internet. You try to resolve the errors by yourself. When the problem is not solved, you can get help from other developers or from colleagues.

There are many resources to get help through internet. The most popular one is Stack Overflow

Tip:1 How to use Stack Overflow?

Java is a pure object oriented programming (OOP) language. It deals with object creation using classes. The classes has attributes and properties inside it.

Need of OOP Concepts:
OOP concepts are needed to solve a large problem by breaking it into smaller problems. Through solving the small problems, it is possible to build a productive complex program.
There are some terms which we need to know before moving to OOP concepts.

Class:
It is a collection of objects. Class act as a blueprint of a house where objects can be created using it by considering it as a template.

In Java name of the class(first letter) starts with capital letter.

class Animal{

private String name;
private int …more at https://thavarajahpraveena.medium.com/oop-concepts-in-java-f0eb16ce498b

In this blog we are going to have a detailed discussion about quality attributes.

Introduction

Non-functional requirements has three categories as given below.

Quality attribute
Business or strategic decisions
Constraints

Quality Attributes

In the software development life cycle quality attributes play a major role in the design, implementation, and development phases.
Business requirements are fulfilled with the quality attributes.
They are testable to fulfil the user requirements and satisfy them. more... https://thavarajahpraveena.medium.com/quality-attributes-ae986c1d326c

Software Requirements

Praveena Thavarajah — Sun, 06 Jun 2021 11:48:39 +0000

Requirements are gathered before developing a system, to deliver the final working product to the client. A developed system should have the capability to fulfil the requirements requested. The requirements may differ from one system to another depending on its stakeholders.

Stakeholders

Stakeholders having a relationship with the product, which is going to be developed by the developers. They can directly or indirectly involve in the project. Stakeholder of a system can be project manager, system administrator, end user, developer, maintainer, and security manager.

It is very important to gather information from each stakeholder who have an involvement with the project. The reason behind this is each stakeholder may come up with different requirements. It is the responsible of the person who is capable to analyse the requirements and prioritize them according to the needs and wants.

Software business analyst of an organization in the IT industry is responsible to analyze the requirements and document them properly. Software architect is the person who is responsible to identify the architectural significance requirements. They check whether the final product developed meets the requirements which is supposed to be.
Requirements are two types as functional requirements and non-functional requirements. They are different from each other. Let us look a brief introduction about the functional requirements and non-functional requirement of a system.

Functional requirements

These are the requirements which are based on specified functionalities.
