THE TINY ADVICE BLOG: UML- A Must-Have for Nigerian Developers

Abeg, you sabi UML?
If you're a Nigerian developer, you might have or not heard of UML before. But trust me, you need to know about it. UML stands for Unified Modeling Language, and it's a way of visualizing and documenting software.
It's used by developers all over the world to create better, more efficient software.
So why should you care about UML? Well, for one thing, it can help you to improve your communication skills.
When you use UML, you can create diagrams that show how your software is supposed to work. This can help you to explain your ideas to other developers, and it can also help you to identify any potential problems with your design.
Another reason why you should care about UML is that it can help you to save time. When you use UML, you can create a blueprint for your software before you start coding. This can help you to avoid making changes later on, which can save you a lot of time and frustration.
So if you're a developer, I urge you to learn about UML. It's a valuable tool that can help you to become a better developer.

Here are some additional tips for developers who are new to UML:

Start with the basics. There are a lot of different UML diagrams, so it’s important to start with the basics. Learn about class diagrams, object diagrams, and sequence diagrams.
Find a good UML tool. There are a number of tools available, both free and paid. Find one that you’re comfortable with and that can help you to create the diagrams you need. Google is your friend for this.
Practice, practice, practice. The best way to learn UML is to practice. Create some diagrams for your own projects, and don’t be afraid to ask for help if you get stuck.

THE TINY ADVICE BLOG: How Phone Cameras Are Made

Naijaversal — Sat, 29 Jul 2023 08:21:04 +0000

Phone cameras are made up of three main parts: the lens, the sensor, and the software.

The lens is what focuses the light that enters the camera. It is made up of multiple elements, which are usually made of plastic.
The lens helps to collect as much light as possible and to focus it onto the sensor.

The sensor converts the light that enters the lens into an electrical signal. The sensor is made up of millions of tiny light-sensitive cells. When light hits a cell, it creates an electrical charge. The sensor then converts these electrical charges into a digital image.

The software is what controls how the camera works. It is used to adjust the settings of the camera, such as the ISO, shutter speed, and white balance. The software also helps to process the image and to make it look its best.

ISO, shutter speed, and white balance are three of the most important settings on a camera. They are known as the exposure triangle.
ISO is a measure of how sensitive a camera’s sensor is to light.
Shutter speed is the amount of time that the camera’s shutter is open.

White balance is the setting that determines how the camera interprets the colors in a scene.
These 3 criteria are the focus of camera quality when a phone camera is manufactured.

Making a phone camera takes the following steps:

The lens elements are made by molding plastic.
The sensor is made by etching a pattern of light-sensitive cells onto a silicon wafer.
The lens and sensor are assembled together.
The camera module is tested to make sure that it works properly.
The camera module is integrated into the phone.
The camera module is integrated into the phone.

Here are some additional things to know about phone cameras:
The number of megapixels (MP) in a phone camera is not the only factor that determines image quality. Other factors, such as the size of the sensor and the quality of the lens, are also important.
Phone cameras can be used to take photos or record videos in a variety of lighting conditions. However, they are not as good as dedicated cameras in low-light conditions.

The Tiny Advice Blog: Critical Thinking Deficits of ChatGPT Developers. The Solutions.

Naijaversal — Fri, 28 Jul 2023 14:34:32 +0000

Every developer in today’s world has made contact with at least one form of artificial intelligence (AI) on the internet. Among the AI tools, Chat Generative Pre-trained Transformers (ChatGPT) stands out and is currently the most popular AI tool right now.
ChatGPT is simply a chat buddy that gives answers to questions. However, this AI cannot give you detailed solutions to challenges you might encounter in your day-to-day job as a developer if you do not input the human aspect of critical thinking into your questions.

Many developers are not aware of this and slowly erode their critical thinking skills through the continuous use of this AI tool.

For example, if a developer creates a full-stack e-commerce web application using code snippets and guides from chatGPT, it is mentally more challenging to get the same developer to design a Unified Modelling Language (UML) for the same web app compared to someone who never consulted the AI chatbot during the process of development.
Developers can avoid this by;

Read and understand every line of code copied from chatGPT rather than copying, pasting, and moving on to another part of the code s long as it works.
Break down every inquiry on chatGPT to the tiniest detail to have a full grasp of what each part of the code does.
Write down every process that gave rise to each inquiry on chatGPT and the line of code generated.

Try these and you’ll be grateful you did
