You’re sitting in a cafe, chilling ☕ — where the drinks are overpriced and the atmosphere is a mix of music, chatter and one guy whose laugh sounds like an engine starting. 🚗 Suddenly, a song starts playing and you know you’ve heard it before. But from where? So you pull out your phone and open Google. Tap “Search a song” 🎶 Hold it up. 🤳 Two seconds later - boom! It knows the song.…

When your code runs, it’s constantly stashing, retrieving, and discarding data, variables that define how your logic behaves. But where does all of this information actually go? Under the hood, your computer has a system, fast, organized, and surprisingly elegant, for deciding where each variable lives, how long it stays there, and how it’s accessed. In this deep dive, we’ll unlock The Memory Vault, revealing how your code uses two powerful storage zones - the…

The Superadmin: Our Industry’s Favorite Shortcut Everyone has their own guilty pleasures.People think developers are addicted to coffee.Cute theory, but coffee never gave us Unlimited Power Mode. Our real addiction, our true obsession, is the Superadmin. Sure, coffee wakes us up…But Superadmin? Superadmin awakens the demon in us. It’s the “touch anything you want, break everything you shouldn’t” account.Irresistible. Illegal. Deliciously dangerous. Every project begins with the same sacred ritual:One insert query in Liquibase or…

Hey everyone! Ever been super proud of a chunk of code you wrote, only to have it blow up in your face later? 🤦‍♂️ That's exactly what happened to me recently. I was building a task manager for a surgery module. It was a pretty complex system with all sorts of entities: surgery_master, TaskMapping, surgery_booking, task_master, and a full-blown Task entity. My code was split into a couple of services and data classes, and I…

Every morning, our mom becomes a silent multitasking magician. She’s making tea, loading the washing machine, chopping vegetables, and waking everyone up almost at the same time. You watch in awe, wondering how it’s even possible. With just two hands, she keeps the entire household moving like a well-coordinated system. Here’s the secret: she’s not actually doing everything at once, but rather switching smartly between tasks. While the tea boils, she folds clothes. When the…

In today’s distributed systems — especially microservices architectures — securing internal service-to-service communication is just as critical as securing public-facing APIs. This blog will walk you through what mTLS is, why it’s needed, and how to implement it with simple step-by-step commands and Spring Boot examples. 💡 Why Secure Inter-Service Communication? We are deploying a new user-service in production. It talks to auth-service, payment-service, and more. These services might be running: On different machinesInside containers…

After months of pushing production builds, debugging late-night issues, and endless Jira tickets, four developers decided it was time for a break. It wasn’t just burnout—they were chasing a phantom. For months, their website had been the source of mounting frustration. No matter how many optimizations they shipped, the homepage crawled. Customers left before it finished loading. Leadership pointed fingers: Was it the APIs? The bloated JavaScript bundles? Nobody knew for sure. A road trip…

The client asked for a new role type with some custom permissions.I opened the PermissionFlag enum, added a few lines, pushed the code...and went to grab a coffee. ☕The change took a minute. Literally. It wasn’t always this simple. What now takes minutes used to take days—modifying the database, adjusting backend logic, and updating the UI for even the smallest change. Each new role or action added layers of complexity. But with the bitmask pattern,…

We all know JavaScript is single-threaded. Yet, when you build a web app, it feels lightning fast. Ever wonder how? Or how does a language with only one main thread keep up with demanding apps and modern UI expectations? In this blog, we’ll break down what "fast" really means. We'll compare it to languages like C++, Rust, and Python—but more importantly, we’ll use real-world analogies (like receptionists and coffee shops) to help you visualize what’s…
