Here's what we cover and why it matters. Networking, DNS, hosting, environments, and the infrastructure your code runs on. If you don't understand what happens after "deploy," start here. Infrastructure security, application security, AI-specific threats, and localhost safety. The stuff that keeps your users (and you) safe. Core programming concepts, patterns, and practices that apply regardless of language or framework. The fundamentals that AI tools assume you know. How data works — types, structures, relationships, validation, and transformation. Understanding data is understanding software. Choosing the right database, data modeling, queries, migrations, and storage patterns. Where your data lives and how to manage it. Best practices for building with AI APIs, prompt engineering, agent architectures, and the unique challenges of AI-powered software. Each section is written to stand alone — you don't need to read them in order. Jump to whatever is most relevant to your current project.
