The Forge.

You don't learn a terminal by reading about one. You learn it by typing into one — wrong, mostly, at first. Every lesson here starts with a blank prompt and a task. Peeking is allowed. Peeking first isn't the point.

The Forge — learn by doing
Modules

Start with the terminal. Everything else assumes it.

Start Here
Read these two before anything else — why any of this matters, and the mistakes that actually hurt.
Software Environments 6 min What We're Building 6 min
Live
Terminal Basics
Four commands. Type them cold before we show you the answer.
The Terminal 5 min Advanced Bash 8 min Python Primer 8 min HTTP & curl 7 min Python API Calls 8 min JavaScript Basics 8 min Server-Side APIs 10 min

Data
One question — "how many of this thing can one person have?" — asked as theory, then answered for real.
SQL — Theory & Practicum 10 min PostgreSQL — Theory & Practicum 10 min
Live
Theory
No exercises here. Just the physics and the definitions everything else in this track assumes you have.
Encryption, Actually 9 min AI Theory & Definitions 8 min
Live
Tokens, Roles & the System Prompt
Two words this track has used unexplained since lesson 01 ("token") and lesson 03 ("role" would've meant nothing) finally get real lessons — in the order you actually need them.
Tokens, Actually 7 min Tokens Lab — Scope & Abilities 9 min Messages, Roles & the System Prompt 8 min
Live
Image & Diffusion Models
A different model family, same discipline: what a diffusion model is actually doing, the different ways one accepts a prompt, and a real production pipeline stage — an LLM improving another model's prompt before it ever generates anything.
Diffusion Models, Actually 8 min Diffusion Lab — Prompts & Expansion 9 min
Live
RAG & Vector Search
Sized to match what other programs actually give this topic — one real session's worth, not a specialty track.
RAG & Vector Search, Actually 7 min RAG Lab — Embed, Store, Retrieve, Ground 9 min
Live
Authentication, OAuth & Cloud
Login, and the other thing every job posting assumes you've touched. Cloud stays short on purpose — a translation dictionary, not a second hands-on track.
Authentication & OAuth 7 min OAuth Lab — Redirect, Code & Exchange 9 min Cloud Concepts 5 min
Live
Security
You just built and deployed real things in the Capstones. Here's how that exposure actually gets attacked, and why the fix that holds was never a smarter reply.
Prompt Injection & Secret Exfiltration 12 min
Live
Toward FireSDK
The bridge from fundamentals to a real product — JP's own SDK. Clone it, install it, call it.
Git & Version Control 8 min Python Environments & Packages 8 min FireSDK Practicum 10 min
Live
Capstones — Real Apps
Everything before this had you typing. Here you write one paragraph, hand it to an agent, and review what comes back.
Capstone: The Recipe Site 7 min Capstone: The Scheduling App 8 min
Live
Critical Thinking — Extra Credit
Optional, standalone sessions — not part of the core sequence above, no prerequisites either direction. Same discipline this whole track teaches, aimed at your own head instead of a model's.
Building a Comparison That Holds 8 min Astrology & Confirmation Bias 7 min
Coming Soon
Talking to a Model
Prompting isn't a magic word. It's an interface — and most people are holding it wrong.
Coming Soon
Agents & Tools
What actually happens between your prompt and an agent doing something in the real world.

Want the deep end? The Forge is free practice. Unleashing AI is the paid seminar — a live agent, a real project, taught by the person who builds all of this for a living.
