What is Kubernetes?

✍️ What is Kubernetes?Let me attempt to explain it as simple as I can.⚡️Kubernetes is a freely-available tool that is used to manage(deploy, destroy, scale, etc) containerized applications.⚡️A containerized application is simply a regular application that won the lottery and is living the dream!How do I mean!? Ever had the thought of what you'd do if you won a billion dollars? You'd most definitely resign from your current job and probably buy a house in one isolatedenvironment 🏠 that has all you need to enjoy life, oblivious of what happens to other people, and just do your thing.

Tech tip of the day

Master asynchronous programming: Asynchronous operations are crucial for modern web applications.

Understand concepts like Promises, async/await, and callbacks to handle asynchronous tasks effectively.

Build a BMI calculator

Write a function that calculates a user BMI. BMI = weight/height^{^2} Your code should request for the user's weight and height and then return their bmi to them. Your return statement should be "[BMI]kg/m^{^2}.

P.S: To simplify, use prompt and alert (depending on how your language calls it) when necessary and make sure your code is testable on the Google Chrome console (developer tool)

How Do You Handle Code Deadlines?

Hello, Africoders! 🌍We've all faced the stress of looming deadlines and felt overwhelmed. Juggling multiple tasks, ensuring the code is bug-free, and meeting the deadline can push anyone to their limits.I was working on a web application project for a client with a tight deadline. The night before the launch, I found myself debugging a stubborn piece of code related to user authentication that just wouldn’t cooperate. Every time I tried to log in, I encountered errors, and I could feel the pressure mounting.As the clock ticked, I knew I had to act quickly. Prioritization became my best...

Coding Bootcamps vs. Traditional Degrees

Hello, Africoders! 🌍Let me take you back to when I was at a crossroads in the early stages of beginning my career. I was facing a critical decision: Should I pursue a traditional degree or enroll in a coding boot camp? This is a dilemma many aspiring developers face, and today, I want to share my journey with you.I was fresh out of high school, eager to do more than just sit in a class and read about programming languages. I wanted to practice the skill and initially thought of spending a year self-learning from online resources. But soon, I realized I needed to take an actual path. On...

More on asynchronous Javascript and Promises

JavaScript thrives on making things happen, but waiting for slow tasks can bring your app to a screeching halt. Enter async/await, a powerful duo that simplifies asynchronous programming with a touch of magic.**Async and Await: A Perfect Match*** **Async Functions:** Imagine a function fetching data. A regular function would block everything until the data arrives. An `async` function, however, returns a Promise immediately, allowing your program to keep running. Read more here https://afr.ng/8cf2385e* **Await to the Rescue:** The `await` keyword pauses execution within an `async` function **u...

Promises in Javascript

This thread will be talking about `promises` and this is a continuation of the async functions post. Click on this link "https://afr.ng/8cf2385e" if you haven't read the async/await post.So JavaScript is all about keeping things moving, but sometimes you have got to wait for something to finish. Promises are here to ensure you don't get stuck in code limbo!**What are Promises?**Promises are objects that represent the eventual completion (or failure) of an asynchronous operation. They act like a placeholder, saying "Hey, I'll get you the result when it's done."**Think of it like an order:** Ima...

Why I Keep My Code DRY

Hello, Africoders! 🌍The first time I truly understood the power of keeping my code DRY was during a late-night coding session. I found myself repeatedly copying and pasting blocks of code to handle a common task across different modules of my application. It was tedious, error-prone, and frankly, exhausting.DRY, or “Don't Repeat Yourself,” isn’t just a coding principle; it’s a mindset shift that promotes efficiency and clarity in software development. Imagine this scenario in a healthcare setting: managing patient appointments. Every time a patient schedules an appointment, the logic b...

Cipher Blocks in Cryptography

Hey Africoders!This semester, my study group and I explored the intricacies of cryptography, focusing on cipher blocks – the building blocks of many encryption algorithms. I'm excited to share some insights we gained!**Cipher Blocks: Segmenting Data for Secure Transmission**At its core, a cipher block is a deterministic algorithm that processes fixed-length groups of bits, known as plaintext blocks. Imagine you have a large text file to encrypt; a cipher block divides this file into chunks of a specific size, akin to how a computer program segments a large array into smaller sub-arrays for eff...

The first computer programmer was a woman - Ada Lovelace!

Hey, Africoders!Did you know the very first computer programmer, the one who wrote the first program, was actually a woman? Her name was **Ada Lovelace**, and while she may not have coded on a modern computer, her work in the mid-1800s laid the groundwork for the entire field of computer programming!Ada Lovelace worked with Charles Babbage on his ambitious Analytical Engine, a machine designed to perform complex mathematical calculations. Though the machine itself was never fully built, Ada, in her notes, theorized about its potential and wrote instructions (the first computer program!) for...
