Introduction In today's digital landscape, security is paramount. The choice of a password hashing algorithm is a critical decision when it comes to safeguarding user data. As one of the most widely used programming languages for web applications, PHP offers several password hashing algorithms to protect passwords effectively. In this article, we will explore and explain in detail some of PHP's most commonly used password hashing algorithms, helping you make an informed decision on the best one for your application. 1. MD5 (Message Digest 5) Strength: Weak MD5 was once a popular choice for hashing passwords due to its simplicity and speed. However, it is now considered obsolete and insecure for password storage. MD5 generates a fixed 32-character hexadecimal hash for any input. One of the main issues with MD5 is its vulnerability to collision attacks, where two different inputs produce the same hash. Notice : Do not use MD5 for password hashing, especially in securi...

Introduction This methodology breaks down software systems into smaller, reusable components, fostering modularity, scalability, and maintainability. In this article, we'll explore the concept of component-based software development and why it is considered a best practice in modern software engineering. What is Component-Based Software Development? Component-based software development (CBSD) is a software engineering paradigm that emphasizes the construction of software systems from reusable components. These components are self-contained, independent units of functionality, often designed to perform specific tasks. CBSD encourages developers to break down complex systems into smaller, manageable parts, promoting a modular and efficient approach to software development. How to achieve this method In many cases, components in Component-Based Software Development (CBSD) are encapsulated in independent files or defined as classes within the codebase, facilitating a h...

Introduction In programming, functions are a vital part of code organization and reusability. A function is a block of code that performs a specific task, making it a basic concept in various programming languages like Python, C++, PHP, and JavaScript. This article explores the essence of functions, provides code examples in these languages, distinguishes between custom and built-in functions, and explains how to implement default values for function arguments. Concept of Functions A function serves as a self-contained unit of code designed to execute a particular job. It streamlines complex tasks, promotes code modularity, and facilitates code maintenance. To understand functions better, let's break down their core components. Anatomy of a Function A function typically consists of the following elements: Function Declaration/Definition : This is where you define the function's name, list its parameters (inputs), and possibly specify its return type. Function Body : W...

  This article would discuss the topic of whether developers who use website builders can call themselves coders. And we will also look at the technicalities involved. To read and understand more about who a coder is or what a website builder is all about, kindly visit this article  (Title : Why you need to be a pure coder )  to learn more.  People who use website builders typically rely on pre-designed templates, visual editors, and predefined features to create websites without delving into the underlying code. While they may engage in some basic customization and content management, their involvement in coding is limited. As such, individuals who primarily use website builders to create websites typically do not qualify as "coders" in the traditional sense. Coding generally refers to the practice of writing and manipulating code using programming languages to create software or websites from scratch or modify existing systems. However, it's worth notin...

A well-planned and executed loop can save you days of repeated tasks, a wrongfully executed loop can cause you loss of biological and machine resources. (Mark Anthony Graham) Introduction Loops in computer programming are like a set of instructions that can be repeated over and over again. They're like a helpful tool that programmers use to make their work easier. With loops, programmers can avoid doing the same task over and over manually. Loops are important because they allow us to do things again and again until a specific condition is met. This is really useful when we need to work with a lot of data or when we have to solve a complex problem that requires multiple calculations. The great thing about loops is that they save time and help us write shorter and more organized code. They do this by automating repetitive tasks. Instead of writing the same code again and again, we can write it once and tell the loop to do it multiple times. This makes our code more e...

  "Reuse engineering is best for the very basic parts of systems, if it not for a basic part then you may likely have some issues" Mark Anthony Graham Introduction Reuse engineering, or software reuse, is the process of using existing software components, frameworks, and libraries to create new software systems. It's like building something new using parts you already have. This practice helps developers work more efficiently, make software easier to maintain, and improve its overall quality. By reusing proven components, developers can save time and effort, reduce costs, and create software that is reliable and consistent. It also encourages collaboration and knowledge sharing among developers, leading to better outcomes. The goal of reuse engineering is to maximize the reuse of software artifacts rather than starting from scratch for every new project. It promotes the idea of building software systems by integrating and modifying existing components rather t...

  Introduction Hello dev, welcome to our next tutorial on JavaScript. We will be learning how to use the switch keyword in this awesome programming language. Kindly note that; it is very important you learn the previous parts if you want to fully understand how to code in JavaScript. If you are just looking forward to revising the switch statement, then it is okay to follow this tutorial. The switch keyword is similar to if...else if...  statement as we had previously looked at. But it is more convenient than if..else if.. statement because it can be used with characters and numbers amongst other types.  Just like a condition function, the block of code associated with the case keyword will be executed if the case's value satisfies the result of the main condition or expression . If none of the cases satisfy the main expression then the block of code associated with the default keyword is executed. There is also the break keyword at the end of every cas...

"If..else if..else statements help to program a hard-wired Ai (Artificial Intelligence) with a barbaric learning ability" ( Mark Anthony Graham ) In this section of the JavaScript tutorials, we will be looking at if..else statements in JavaScript. I recommend you learn our previous tutorial on JavaScript Operators (link) .  Remember each concept in JavaScript builds upon the other. With that being settled, let's look at the general understanding of an if..else statement .  What could first come to your mind is a condition.  That's correct✅. When you use the if..else statement as a coder, it means you are defining a case and that if the condition of the case is satisfied then the block of code set to that condition would be executed by the machine. Illustration of a condition From, the diagram, the condition must return a value of either true or false. If it returns true,  it means that the little girl must take the left turn and in case the condition ret...

  " The mind of the coder is written in the mind of the computer, developers have a connection with what they create " (Mark Anthony Graham) Introduction Hello Devs, am super excited to share with you what psychology says about coding, you would be glad to know more, kindly stick with me on this one, as we journey through psychology and codes😀. It feels great to learn psychology and coding, the feeling may be subjective as I had the chance to read both worlds. Psychology offers a good understanding of people, their minds (mental processes) and their behavior. Coding offers a good understanding of communicating with a machine through computer programming languages. The blend between psychology and coding is wonderful. If I'm being bizarre as a psychologist. "Feels like coding gives you the opportunity to create an Ai (artificial intelligence) that would run on a mental process specifically designed by you." This is not new development though, as Go...
