The library is open.

Everything on this shelf is free: a handbook, a masterclass and a browser playground for learning SimPy; three books and a sample on building with AI. The steepest price on this page is an email address.

Take what you need.

The new sample first, then the rest in roughly the order most readers take them. Each item lives on its own page; the books are also on Amazon if you prefer reading on a Kindle.

  1. Agentic Engineering for the Rest of Us

    Free sample: Chapters 1 to 3, PDF and EPUB

    Don’t marry the model: the four coding agents that matter and the habits that carry between them, so a provider’s bad week costs you an afternoon, not your workflow. The first three chapters are free now.

  2. The SimPy Handbook

    eBook + runnable code

    The documentation tells you what SimPy’s functions do; the Handbook shows you what to build with them. Queues, resources, priorities and the handful of patterns behind almost every working model, with code you can run as you read.

  3. The free masterclass

    40-minute recording

    A factory simulation built from a blank file in forty minutes: scoping, coding and analysis, with the planning framework that holds a real study together. The closest thing to sitting beside a practitioner while he works.

  4. The SimPy Playground

    Browser tool

    SimPy in your browser: no installation, no environment to wrangle, nothing to configure. Worked industry examples you can edit, run and break in perfect safety.

  5. Vibe Modelling

    eBook

    What happens when you describe a digital twin instead of typing it? A six-step framework for building simulation models with AI assistance, with engineering rigour kept firmly in charge.

  6. The Ralph Loop

    eBook + EPUB

    A practitioner’s guide to autonomous AI coding with fresh-context iteration: the theory, the practice and the troubleshooting, for Claude Code and beyond.

  7. Claude Code for the Rest of Us

    eBook

    Twenty-three chapters for the product managers, analysts and designers who want to build real software with AI and have never written a line of code. None is required.

Simulation is better in company.

A model that misbehaves at five o’clock on a Friday misbehaves quietly; nobody else in the office knows why you are glaring at a traceback. The cure is almost always another practitioner. Two rooms are kept warm:

  • r/SimPy

    The subreddit: quick technical questions, working code and the occasional shared triumph.

  • Simulation in Python on LinkedIn

    The professional room: industry discussion, opportunities and people worth knowing.

When the free shelf has done its work.

The books and the masterclass will carry you a long way; the courses carry you the rest of the distance, with structure, real projects and an instructor on hand.
