If you’ve been on the fence about trying the Ash Framework, this post is for you. We’re going to explore why Ash is a game changer for Elixir developers by building something complex, real, but surprisingly elegant. We’ll create AshTherapy, an AI-powered therapeutic chat service that handles conversations, messages, and user interactions — all powered by Ash. Before we go further, let’s first answer the question: what exactly is Ash?

You might have heard about Prism, the new Ruby parser. Perhaps you've heard it's faster, more reliable, and more powerful than what we had before. Or maybe you never took a compilers class and aren't sure about what this actually means. I'm here to tell you all about it, and how it's changing our lives as Ruby developers. Today, I want to take you from square one to writing your first transpiler.

In recent years, Markdown has become the lingua franca of plain-text files on the web. If you're a developer, you have read — and maybe even written — hundreds of Markdown documents over the course of your career. GitHub repositories use README files written in Markdown. Stack Overflow and Reddit use it to format posts. Technical documentation, blog posts, and entire books are written in Markdown. And it's not just for humans either!

When developing web applications with Django, your interaction with the database impacts overall application performance. Django's Object-Relational Mapper (ORM) is a powerful ally that offers an intuitive way to work with your data through abstractions called QuerySets. These are your primary tools for fetching, filtering, creating, and managing data. In this article, we'll explore fundamental — yet highly effective — techniques to optimize your Django QuerySets.

Prisma is a modern open-source database toolkit designed to simplify data workflows for developers. It provides a powerful and intuitive way to interact with databases, and it is type-safe. Prisma works well in a monorepo because it can be used in both the frontend and backend of a full-stack application. This enables developers to share types and logic across the entire codebase, resulting in a more efficient development process.

In part one of this series, we started developing a simple Flappy Bird clone game using the DragonRuby game development toolkit. We didn't come very far, though — we stopped after integrating player input to keep our plane afloat. In this second and concluding part, we'll implement the remaining simple game mechanics. We'll also take a brief look at interfacing with an HTTP server and publishing our game on itch.io.

Cowboy is a small, fast, and modern HTTP server for Erlang/OTP. It particularly shines when handling multiple concurrent connections with minimal overhead. This makes it a perfect choice for building lightweight, real-time streaming services. In this article, we’ll build a tiny real-time text pub/sub server using Cowboy. Our service supports HTTP-based publishing, allowing clients to subscribe using either WebSockets or Server-Sent Events (SSE).

Boosting the scalability of your backend applications often means rethinking how you manage asynchronous data. That’s where reactive programming comes into play: a paradigm that treats data streams as first-class citizens, allowing your code to respond to data changes as they occur. While Node.js wasn’t built with reactive programming in mind, libraries like RxJS and Bacon.js support that approach.

In parts one and two of this series, we familiarized ourselves with the ins and outs of Showcase. Now, we'll dive into samples, Showcase's main feature. Samples show how a component can be used in a real application.

The DragonRuby Game Toolkit is a powerful, cross-platform 2D game engine that allows you to create fun game titles while staying in your favorite developer-friendly language. What's not to love? In this post, we are going to cover the basics of game development with DragonRuby. We will use a "Flappy Bird" clone to explain the fundamental concepts. But before we get started, let's address two initial concerns you might have about DragonRuby right off the bat.
