Six itemsThe library
The library is open.
Everything on this shelf is free: a handbook and a masterclass for learning SimPy, three books on building with AI and a playground that runs in your browser. The steepest price on this page is an email address.
01 The shelf
Take what you need.
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.
-
eBook + runnable code
The SimPy Handbook
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.
-
40-minute recording
The free masterclass
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.
-
Browser tool
The SimPy Playground
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.
-
eBook
Vibe Modelling
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.
-
eBook + EPUB
The Ralph Loop
A practitioner’s guide to autonomous AI coding with fresh-context iteration: the theory, the practice and the troubleshooting, for Claude Code and beyond.
-
eBook
Claude Code for the Rest of Us
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.
02 The company
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.
