Stories Covered

Concurrency, Christmas, and the Ultimate Programmer

It’s the Christmas season, and I’ve been reflecting on something that has fascinated me since I was a child. There are billions of people in the world, all living different lives, making choices, building dreams, and facing struggles simultaneously. Life does not take turns. It runs in parallel. Sometimes our paths intersect. Sometimes they do not. Yet everything keeps moving. For a long time, I could not fully wrap my head around this. Later, while studying Computer Science, I encountered the c

Level Up Your Code: Why Object-Oriented Programming (OOP) is the Backbone of Game Dev

This is a great topic for the Dev.to community! Developers there love practical, architectural insights that help them write cleaner code. If you’ve ever looked under the hood of a modern game engine like Unreal (C++) or Unity (C#), you’ll find one common denominator: Object-Oriented Programming. While functional and data-oriented approaches are gaining traction, OOP remains the primary mental model for building complex, interactive worlds. In this post, we’ll explore how the four pillars of OOP

JSON vs YAML vs TOML: Which Configuration Format Should You Use in 2026?

You're starting a new project. Time to create a config file. You open your editor and pause. Before we dive deep, here's the quick comparison: Born: 2001 Born: 2001 Born: 2013 Now let's see how they actually stack up in real-world scenarios. Let's represent the same configuration in all three formats. JSON { "database": { "host": "localhost", "port": 5432, "credentials": { "username": "admin", "password": "secret123" }, "pools": [ { "name": "primar

The 5GB "Sudo Access" for Global Internet: My Review of eSIMFree.org

404 Connection Not Found If you are a remote developer or a digital nomad, you know the panic. You just pushed a hotfix, you're hopping on a train/plane, and suddenly—latency spikes to 5000ms or the connection drops entirely. Hotel Wi-Fi is usually throttled, and airport Wi-Fi is a security nightmare (packet sniffing, anyone?). I recently audited my "Connectivity Stack" for 2025. I wanted a redundant, fail-safe internet layer that didn't cost me $10/day in roaming fees. That's when I found a pro

Introducing a new Front-End Framework

The front-end ecosystem has long been dominated by state-driven and component-based frameworks. While these approaches are powerful, they often introduce unnecessary complexity for form-centric, enterprise, and command-driven applications. WebForms Core was created to challenge this assumption. Initially introduced as a Server-Command/Client-Execution technology, WebForms Core focused on unifying UI logic across different back-end languages while keeping the front-end lightweight. With the relea

Java ATM CLI Dev Log #3: VTU Features

Building this feature, was easy to say the least. The volume of code to write was much but with the help of Gemini (via Gemini Code Assist), I was able to write everything out. One thing I did which I didn't like is how I hardcoded the airtime plans and data plans into the code. I did it because I want it to work first, and now it is working, what I will do now is to put the VTU plans into the database and retrieve them when needed. That's how it's done. While running the code, I noticed a UX fl

🐻 Introducing Zustand Copilot: The Ultimate VS Code Extension for Zustand State Management

If you've been working with Zustand for state management in React, you know how elegant and powerful it is. But what if you could make your Zustand development experience even better? Today, I'm excited to announce Zustand Copilot — a VS Code extension designed to be the definitive toolkit for Zustand v5+ development. After building dozens of React applications with Zustand, I found myself: 📝 Typing the same store boilerplate over and over 🔍 Constantly switching to docs for syntax reference 😓

Publishing Pipeline v1.2.0 – backlinks and X support

There is good news about this project and its progress: we are adding a new feature: Tweeting on X! The pipeline now supports tweeting on X in addition to WordPress and Dev.to. WordPress remains the canonical source. This means: A post is considered authoritative once it exists on WordPress Any downstream platform (Dev.to, X, LinkedIn, etc.) builds on that state Republishing only happens when the content actually changes This avoids duplicate work and keeps all platforms consistent. So far, this

Tracing the Meaning of a Word: Rendering (Bite-size Article)

Introduction In the field of web development, Rendering refers to the process of taking information such as HTML, CSS, JavaScript, or application state and data structures, processing them, and generating or updating something humans can perceive—in other words, a screen or user interface. Typical examples include component rendering in frontend frameworks like React, update handling via the virtual DOM, and server-side rendering (SSR). In modern web development, these mechanisms are intricate

Scrapy HTTP Cache: The Complete Beginner's Guide (Stop Hammering Websites)

When I first started building spiders, I'd test them by running them over and over. Each time I tweaked a selector, I'd run the spider again. Hit the website again. Download the same pages again. After my 50th run in one day, I realized something: I was being a terrible internet citizen. I was hammering some poor website with hundreds of requests just because I couldn't write a CSS selector properly. Then I discovered Scrapy's HTTP cache. Game changer. Now when I test my spiders, they fetch page
