What Is "the Cloud"? Cloud Computing for Beginners
The cloud is other people's computers, rented by the minute. What cloud computing actually is, the difference between IaaS, PaaS, and SaaS, what AWS, Google Cloud, and Azure sell, how cloud billing works, and how much of it a first app really needs.
What Is Serverless? (There Are Still Servers)
Serverless means you write functions and the platform runs them on demand — no servers to manage, pay per use. What serverless really is, how it differs from an always-on server, cold starts, timeouts, and the database connection problem, and when it's the wrong fit.
What Is React? A Beginner's Guide to the Library Behind Most AI-Built Apps
Lovable, Bolt, v0, and Claude Code all tend to produce React. What React is, what components, props, and state mean, how to read a .jsx file, what hooks like useState and useEffect do, and the React mistakes AI tools make most often.
What Is Rate Limiting? Protecting Your App From Too Many Requests
Rate limiting caps how many requests someone can make in a period. Why every public app needs it — for login forms, sign-ups, AI features, and APIs — how it works, what a 429 response means, where to add limits, and what to do when you hit someone else's.
What Is Node.js? JavaScript Outside the Browser, Explained
Node.js lets JavaScript run on servers and on your computer, and it's behind npm, most AI-built backends, and tools like Claude Code's ecosystem. What Node.js is, what it's used for, LTS versions, how to install it properly, and the errors beginners hit first.
What Is Next.js? A Beginner's Guide
Next.js is the React framework that v0 and many AI tools produce by default. What it adds on top of React, how file-based routing works, server vs client components, API routes, what 'rendering' means, and what you need to know to deploy it.
What Is MCP? The Model Context Protocol for Beginners
MCP is a standard way to plug tools and data into AI apps — a USB-C port for AI. What the Model Context Protocol is, what servers and clients are, what tools, resources, and prompts do, real examples, and the safety questions to ask before connecting one.
What Is Markdown? The Formatting Language You're Already Using
Markdown is plain text with a few symbols for formatting — # for headings, ** for bold, - for lists. It's used in READMEs, GitHub, docs, notes apps, CLAUDE.md files, and AI chat. The full basic syntax on one page, plus tables, code blocks, and the gotchas.
What Is Localhost? (And Why Your Friend Can't Open Your Link)
You send someone http://localhost:3000 and it doesn't work for them. That's because localhost means 'this computer' — yours, and only yours. What localhost and ports are, how to share an app you're working on, and why localhost sneaks into apps that are supposed to be live.
What Is JSON? A Five-Minute Guide
JSON is the text format apps use to send data to each other — every API response, many config files, and a lot of what your AI tool writes. How to read it, the six kinds of values it can hold, the mistakes that make it invalid, and where you'll meet it.
What Is HTTPS? The Padlock, Explained for Beginners
HTTPS is why the browser shows a padlock instead of 'Not secure'. What it protects, what it doesn't, what a certificate is, why your app needs it before launch, and how to fix the common 'mixed content' and certificate errors.
What Is Docker? A Beginner's Explanation
Docker packages an app with everything it needs to run, so it works the same on any computer. What containers and images are, how they differ from virtual machines, why hosts and AI tools use them everywhere, and whether you need to learn Docker at all.
What Is CRUD? The Four Operations Behind Almost Every App
Create, Read, Update, Delete: most app features are some combination of these four. What CRUD means, how it maps to SQL and HTTP methods, what a CRUD API looks like, and the details — validation, permissions, pagination — that separate a demo from a real app.
What Is Claude Code? A Beginner's Guide
Claude Code is Anthropic's AI coding agent: instead of just suggesting code in a chat, it reads your project, edits files, runs commands, and checks its own work. What it is, where you can use it, what it costs, and how to get started without getting into trouble.
What Is CI/CD? Continuous Integration and Deployment for Beginners
CI/CD means every change is automatically checked, and working changes are automatically shipped. What continuous integration, delivery, and deployment are, what a pipeline does, why it matters when AI writes your code, and the smallest useful setup for a solo builder.
What Is an ORM? Prisma, Drizzle, and Friends Explained
An ORM lets you work with your database using your programming language instead of raw SQL. What ORMs are, what Prisma, Drizzle, and others look like, the schema-and-migration workflow, the N+1 trap, and when writing SQL directly is the better choice.
What Is an LLM? Large Language Models Explained Without the Hype
Claude, GPT, and Gemini are large language models. What an LLM actually is, how it's trained, why it's good at code, why it confidently makes things up, what 'model', 'prompt', and 'temperature' mean, and what that means for building apps with AI.
What Is an API? Explained Without the Jargon
APIs are how apps talk to each other — how your app takes a payment, sends an email, or asks an AI model a question. What an API actually is, what requests and responses look like, what an API key does, and the few terms you'll keep running into.
What Is an AI Coding Agent? (And How It's Different From a Chatbot)
AI coding tools come in three flavours: chatbots that answer, assistants that autocomplete, and agents that take actions — editing files, running commands, and checking their own work. What makes something an agent, why it matters, and what agents need to work well and safely.
What Is a Webhook? Explained for Beginners
A webhook is how another service tells your app that something happened — a payment went through, a form was submitted, a file finished processing. How webhooks differ from normal API calls, what you need to receive one, and the three safety rules every webhook handler must follow.
What Is a Tech Stack? How to Choose One When AI Writes the Code
Your tech stack is the set of tools your app is built from: language, framework, database, and hosting. Even if AI writes the code, the choice matters — for how well the AI performs, what it costs, and who can help you later. A beginner's guide with a safe default.
What Is a Server? A Plain-English Explanation
'Server' can mean a computer, a program, or a rented slice of a data centre. What a server actually is, what it does when someone visits your app, the difference between physical, virtual, and serverless, and why your laptop isn't a good one.
What Is a Pull Request? A Beginner's Guide
A pull request is how a change gets proposed, checked, and merged into a project — and it's the single best safety net when an AI agent is writing your code. What PRs are, how they work on GitHub, what to look at before you click Merge, and why you want one for every change.
What Is a JWT? JSON Web Tokens Explained Simply
Supabase, Firebase, Auth0, and Clerk all hand your app JWTs. What a JSON Web Token is, its three parts, why anyone can read it but nobody can forge it, how apps use it for login, and the mistakes AI-generated code makes with tokens.
