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...
