React Hook Rules You Should Never Break React Hooks are a powerful feature that let you use state and other React features in functional components. However, to work correctly, hooks have some strict rules. Breaking these rules can cause bugs, unpredictable behavior, or errors. 1. Only Call Hooks at the Top Level Do not call hooks inside loops, conditions, or nested functions. Always call hooks at the top level of your React function component or custom hook. This ensures hooks are called in the same order every time a component renders. Why? React relies on the order of hook calls to associate hook state correctly. Calling hooks conditionally can break this order. Wrong: jsx Copy Edit if (userLoggedIn) {   useEffect(() => { /* ... */ }); } Right: jsx Copy Edit useEffect(() => {   if (userLoggedIn) {     // your effect code   } }, [userLoggedIn]); 2. Only Call Hooks from React Functions Call hooks only from: React function components Custom hooks (function...

Using Variational Autoencoders (VAEs) for Generating Realistic Images and Text What is a Variational Autoencoder (VAE)? A Variational Autoencoder (VAE) is a type of generative model in machine learning that learns to represent data in a compressed latent space and generate new, similar data by sampling from that space. It consists of two parts: Encoder: Compresses input data (like an image or text) into a lower-dimensional latent representation. Decoder: Reconstructs data from the latent representation, generating outputs similar to the original input. Unlike traditional autoencoders, VAEs impose a probabilistic structure on the latent space, encouraging it to be continuous and smooth. This allows meaningful sampling and generation of new data. How VAEs Generate Realistic Images Training: The VAE learns to encode images into latent vectors with a distribution (usually Gaussian). It also learns to decode latent vectors back into images. The loss function includes a reconstruction loss (...

Understanding Flask for Full Stack Development What is Flask? Flask is a lightweight, flexible, and easy-to-use web framework written in Python. It is designed to help developers build web applications quickly and with minimal code. Flask is often described as a microframework because it doesn’t include built-in tools for things like form validation, database abstraction, or authentication — but it gives you the freedom to plug in only what you need. Why Flask is Useful in Full Stack Development Full stack development involves working on both the frontend (client-side) and backend (server-side) of a web application. Flask plays a major role on the backend by handling: Routing (URLs) Request handling (GET, POST, etc.) Templating (using Jinja2) Interacting with databases Serving APIs Flask can also work well with frontend frameworks like React, Vue, or Angular, making it a great choice for full stack projects. Core Features of Flask Routing – Define URL endpoints and what happens when th...

Building a Pagination API with MongoDB Overview Pagination is a common technique used to divide large datasets into smaller, more manageable chunks (pages). This is particularly useful for APIs that return data lists, such as blog posts, products, or user records. MongoDB supports efficient pagination using queries with limit() and skip(), or more efficiently, using range-based pagination (also known as cursor-based pagination) with a sorting key. Approaches to Pagination 1. Offset-based Pagination (Skip & Limit) This is the simplest and most common approach. Example Query: javascript Copy Edit db.users.find().skip((page - 1) * pageSize).limit(pageSize); API Example (Node.js with Express): javascript Copy Edit app.get('/users', async (req, res) => {     const page = parseInt(req.query.page) || 1;     const limit = parseInt(req.query.limit) || 10;     const skip = (page - 1) * limit;     const users = await db.collection('users')   ...

 Message Sharding and Load Balancing with Cloud Pub/Sub Overview Google Cloud Pub/Sub is a messaging service designed to support global-scale messaging between independent services. When working with large-scale systems, you may need to distribute (or "shard") messages across different consumers to ensure that the workload is processed efficiently and without bottlenecks. Load balancing helps you scale your system by spreading the load evenly among your subscribers. Message Sharding Sharding is the process of dividing messages into distinct segments based on some key (e.g., user ID, device ID, geographic region). Each shard can then be processed independently. Why Use Sharding? To process messages in parallel. To maintain order within each shard. To ensure that a specific type of message always goes to the same consumer (e.g., all messages related to a single user). How to Implement Sharding in Pub/Sub: Add a Shard Key to the Message: When publishing messages, include a custo...

🐳 Docker for Beginners: Containers Demystified If you're new to Docker and containers, don't worry—you’re in the right place! This guide will help you understand what containers are, what Docker does, and how you can use them without any prior experience. 🌍 What Is Docker? Docker is a tool that helps developers build, package, and run applications. It does this using something called containers. Imagine you’ve built an app on your laptop. It works fine. But when you move it to a different computer or server, it suddenly doesn’t work anymore. That’s a common problem due to differences in environments. Docker solves this problem by packaging your app along with everything it needs to run—code, libraries, and settings—into one container. This container will work the same no matter where you run it. 📦 What Are Containers? A container is like a small, lightweight virtual computer that runs your app. It has everything the app needs, but it shares the host system's operating sy...

🔐 How SIM Swapping Attacks Work SIM swapping (also called SIM hijacking) is a type of identity theft where an attacker tricks a mobile carrier into transferring your phone number to a SIM card they control. Once they have control of your number, they can intercept SMS messages and phone calls, allowing them to bypass two-factor authentication (2FA) and gain access to your accounts. 🧠 Step-by-Step: How the Attack Works 1. Target Identification The attacker gathers personal information about the victim. This can include: Full name Phone number Date of birth Address Last 4 digits of a Social Security Number (SSN) or ID Sources: Social media Data breaches Phishing Public records 2. Social Engineering the Mobile Carrier The attacker contacts the victim's mobile provider, posing as the victim. They request a SIM swap — often by claiming: The phone was lost or stolen A new device needs to be activated They then convince customer service to: Deactivate the victim’s current SIM Activate a...
