Why a Rules Engine? Before we start slinging code, let's talk about why you'd want a rules engine in the first place: * Separates business logic from core application code * Allows non-technical folks...

The Actor Model, implemented through systems like Akka, can significantly boost your microservices' concurrency handling. It excels in scenarios with high message throughput, complex state management, and where traditional thread-pool designs fall short. We'...

Let's quickly recap why traditional CRUD-based REST APIs fall short when dealing with complex workflows: * Lack of state representation * Difficulty in handling long-running processes * No built-in support for rollbacks or compensating transactions * Limited ability...

Multi-tenancy is a crucial architectural decision that can make or break your application's scalability and cost-effectiveness. But here's the kicker: implementing multi-tenancy in a microservices is challenging, it's dangerous, and...

In this article, we'll explore the fascinating challenge of creating a Sim card app for the legendary Nokia 3310. Why, you ask? Because sometimes, the best way to appreciate how far we've...

Zig is a general-purpose programming language designed to be simple, yet powerful. It aims to provide the performance of C with the safety of Rust, but without the cognitive overhead that comes with Rust's...

zk-SNARK stands for "Zero-Knowledge Succinct Non-Interactive Argument of Knowledge". Yeah, that's a mouthful. Let's break it down: * Zero-Knowledge: You prove you know something without revealing what that something is. * Succinct:...

The event loop is the heart of Node.js, pumping asynchronous operations through your application like blood through veins. It's single-threaded, which means it can handle one operation at a time. But don'...

JVM, Go, and Rust each have unique approaches to handling data races: * JVM uses a happens-before relationship and volatile variables * Go embraces a simple "don't communicate by sharing memory; share memory by communicating&...

TL;DR We'll implement a resilient Saga pattern using gRPC to manage distributed transactions across microservices. We'll cover the basics, show you how to set it up, and even throw in some...

The Dependency Dilemma: Why It's a Big Deal Let's face it: managing dependencies in a monolith is child's play compared to wrangling them in a microservices architecture. Here's...

The Humble Beginning: Your Source Code Let's start with the most basic C++ "Hello, World!" program: #include int main() { std::cout << "Hello, World!" << std::endl; return...

Let's kick things off with a classic blunder: the "index all the things" approach. It's a tempting strategy, isn't it? If one index speeds things up, surely ten...

What Are Dark Patterns, Anyway? Before we don our cybersecurity capes, let's get our terminology straight: Dark patterns are user interface design choices that benefit an online service by coercing, steering, or deceiving users...
