Real-time features are becoming increasingly important in web applications, but not every Rails developer is familiar with Action Cable, the framework's built-in WebSocket library. Rails Action Cable has long supported web sockets, but comes with some additional complexity. Rails 8 introduces Solid Cable, a new database-backed adapter for Action Cable that eliminates the need for Redis. In this guide, I'll walk you through Action Cable by way of Solid Cable and show you how to build a real-time feature.

From smart home automation to self-hosted API backends, discover what the humble Raspberry Pi can really do as we head into 2026. As we close out 2025 and look ahead to 2026, the Raspberry Pi continues to punch well above its weight class. What started as an educational tool has evolved into a legitimate platform for home servers, IoT hubs, development environments, and even production-grade API backends.

The app economy today is driven by experiences that are fast, fluid, and personalized, and Flutter sits at the heart of this transformation. As businesses move beyond native silos to embrace unified digital ecosystems, Flutter enables them to build scalable, high-performance apps that deliver consistent experiences across platforms, all from a single codebase.

REST APIs are the basis of all interactions between different applications. Many companies and organizations today offer APIs to interact with their applications. REST APIs allow third-party application developers to perform operations such as transmitting or accessing data from one application to another. This is called a public API. This means that this API is intended for interaction with third-party apps.

The global supply chain landscape continues to evolve at a relentless pace. Following years of pandemic-driven supply chain disruptions, the focus has shifted from survival to building long-term resilience and leveraging new technologies for competitive advantage. Drawing from a recent industry conversation, here are the key trends that will define the supply chain outlook in 2026.

In the industrial landscape of 2026, data is no longer just a byproduct of production—it is the primary driver of operational efficiency. However, a significant gap remains: the Integration Gap. While factories are teeming with sensors, ERPs, and PLCs, the ability to deliver that data to real-time applications remains a manual, slow, and often insecure process.

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.

If your 2026 resolution is to finally get AI costs under control, we've got you covered. Every January, the same resolutions show up: eat better, exercise more, finally learn that language, finally figure out that production use case for AI agents (OK, this one isn’t so typical unless you operate in our universe). But if you're responsible for your organization's AI strategy, we'd like to suggest a different one for 2026: stop letting AI be a cost center.
