Today, we're diving into one of Rust's most powerful and sometimes intimidating features: declarative macros. If you've spent any time with Rust, you've used macros. Every time you write println!("Hello, {}!", name) or vec![1, 2, 3], you're using one. In simple terms, a macro is code that writes other code at compile time.

Understanding how multitasking and multithreading work in Java is essential for any developer aiming to build high-performance, scalable applications. Whether you are developing standalone software, interactive games, or enterprise-level web applications, leveraging. In this blog, we'll break down the concept of multitasking in Java into simple terms.

In this tutorial, we’ll show you how to customize the Spring Boot banner that appears when starting your application. If you're looking to add a personalized message, brand identity, or dynamic app details such as the version number, you've come to the right place.

As backend developers, we're deeply familiar with how APIs work. We know which requests are accepted, what responses are returned, what headers are required, and which HTTP methods are used. But the people using our APIs, such as frontend developers, QA testers, or third-party clients, don’t always have access to that same level of understanding. Unless we clearly document our API, they’re left guessing or constantly asking for clarification.

Learn how to use HTTP status codes effectively in your FastAPI projects for clear, consistent API responses. Whether you're building a backend with FastAPI or consuming an external service, understanding and using the right HTTP status codes helps ensure clear communication, better debugging, and a professional API interface.

You've probably written trait constants before, but have you ever needed to validate them? Maybe ensure a string isn't too long, or a number falls within a specific range? Here's the thing: you can actually enforce these constraints at compile time, not runtime.

Why does Rust do this? It prevents conflicts. Imagine if two different crates both tried to implement the same trait for the same type; this would be a problem as the compiler wouldn't know which implementation to use. In less than 5 minutes, you'll learn how to create extension traits, adding methods to foreign types. By the end of this article, you'll have learned something really interesting.

Choosing the right programming language for backend development in 2025 can be overwhelming, especially for beginners. But how do you know which one is better for your backend development needs? Let's compare the two in depth to help you decide.

In this guide, I’ll walk you through setting up OAuth 2.0 authentication in a Spring Boot application. We’ll integrate both Google and GitHub for authentication, giving users a choice of login services. I’ll also show you how to protect your API endpoints using JWT (JSON Web Tokens), ensuring that only authenticated users can access your resources.

So you have decided to join the ranks of the not so elusive Node.js backend developers. This could be the best decision you’ve made or the worst, depending on who you are. You've got to put in the work to learn to become a backend developer, and I am just in the position to let you know how with a few tips, tricks, and suggestions.

Rust enums are incredibly powerful for modeling data, but newcomers quickly discover a frustrating limitation: you cannot iterate through enum variants natively. We will show you exactly how to use strum to iterate through enum variants, convert enums to strings, parse strings back to enums, and leverage other powerful features that make working with enums much more pleasant.

The as keyword in Rust serves three critical purposes that every developer should master. Understanding these use cases will significantly improve your code clarity and prevent common compilation errors.

Choosing a programming language can be a tough decision, especially for beginners or those transitioning into tech. There are several factors to weigh, including job opportunities, ease of learning, and long-term career growth.

In Rust, aside from variables and struct fields, you can also bind memory to patterns. Some of these patterns are used by the compiler to signal certain conditions. This is the point of this article: how does the Rust compiler know you'll use a variable?

Understanding Sized unlocks deeper comprehension of why Rust behaves the way it does with generics, function parameters, and memory management. Most importantly, it explains the mysterious ?Sized syntax you've probably encountered in advanced Rust code.

If you're looking to land your next backend developer role, one of the most important tools in your job search is a strong resume. In this guide, we’ll walk you through everything you need to know to write a backend developer resume that stands out.

This year, Java continues to be a cornerstone for building scalable, secure, and reliable solutions. In this blog post, we’ll walk you through the step-by-step journey of becoming a proficient Java backend developer.

If you're a beginner looking to start a career in backend development or an experienced developer exploring the latest trends, this guide will take you through everything you need to know—from core concepts to advanced backend architectures.

In this article, we'll walk through how Cow<T> works, how to use it in your structs and functions, the benefits and trade-offs of using it, and a few common pitfalls to avoid—so you can write clean, efficient Rust code without over-engineering your ownership logic.

What’s better for development: JavaScript or TypeScript? We dive into these languages and discuss their differences as well as which one we believe you should use in your next project.

The need to build full-stack applications that are fast, scalable and easy to maintain is now more important than ever. In this article, we’ll build a simple full-stack Bookstore application to show key CRUD operations using the FARM stack.
