Add a product to a Shopify store the default way and the whole page reloads. The shopper is looking at your product, they click Add to cart, and the browser throws the page away and rebuilds it. On a slow connection, that’s two or three seconds of blank screen. Sometimes they even land on /cart, […]

In this tutorial, I’ll show you how to build a private local RAG-powered Q&A AI agent for your personal documents using LangChain v1, Ollama, Qwen, and Python. The agent reads your documents and answers questions about them with cited sources, all running on your own machine to preserve privacy. Table of Contents Background What Are […]
AI coding assistants have evolved from simple autocomplete tools into capable development agents that can write code, debug applications, refactor projects, and even execute complex workflows. Among the newest generation of tools, OpenAI’s Codex and Anthropic’s Claude Code have emerged as two of the strongest options for developers. Both platforms promise to improve productivity, reduce […]
Cloudflare Tunnel is a secure tunneling solution that allows developers to expose local applications and private services to the internet without opening inbound ports or changing firewall rules. Instead of accepting direct incoming traffic, Cloudflare Tunnel creates an outbound connection to Cloudflare’s network and routes requests through its global edge infrastructure. This approach improves security […]
Scaling large AI models requires more than just raw computing power. It demands sophisticated techniques to distribute workloads efficiently across hardware. We just posted a new course on the freeCodeCamp.org YouTube channel, where instructor Kian Kyars provides a hands-on guide to mastering Distributed Data Parallelism (DDP). The course shows you how to overcome memory limitations […]
Computers are incredibly fast, but they have a surprising, fundamental flaw when it comes to counting money. In our latest freeCodeCamp.org video, “Why Computers Can’t Count Money,” Ania Kubow dives into the history of a class of software bugs that once challenged major financial institutions, leading to accounts that gained or lost funds due to […]
Building your own AI agent has never been more accessible. We just released a comprehensive new course on the freeCodeCamp.org YouTube channel that guides you through building a powerful, persistent AI agent from scratch, inspired by the popular open-source project OpenClaw. In this project-based course, instructor Shawn Esquivel takes you through the entire development lifecycle, […]
When you build a feature that streams data, like an AI chat response or a live notification feed, the network is rarely as cooperative as fetch makes it look. Connections drop, proxies buffer responses, and mobile networks switch from WiFi to cellular mid-stream. If your streaming code doesn’t plan for this, the user sees a […]
A few years ago, the first day I finally got access to an AI image generator, I was so excited that I immediately sat down and wrote an article about it (using Node.js and OpenAI’s DALL-E). The magic of turning thoughts directly into digital pixels felt like holding a real-life magic wand. But back then, […]
Your Garmin shows poor recovery, WHOOP paints your day red, your resting heart rate is high, your HRV is low, and the app recommends that you rest. But here’s the thing: you don’t actually feel bad. For women who are in their reproductive years, chances are your wearable technology has misread your luteal phase symptoms […]
