Build a computer
Start with device physics, compose logic and arithmetic, then step through real machine architectures.
A learning-first monorepo
Build the stack.Inspect every layer.
Coding Adventures is a working laboratory for computing from first principles. The repository follows ideas from transistors and logic gates through languages, runtimes, UI systems, and complete products—without hiding the seams.

Measured on main · 2026-08-28The scale is deliberate: each package stays small enough to inspect, while parity lanes expose the same ideas across languages and runtimes.
Three ways in
Pick a thread.
Follow it end to end.
Each route crosses specifications, teaching material, reusable packages, tests, and a runnable surface. The destination matters; the layers are the lesson.
Design a language
Follow text from grammar and tokens through parsing, analysis, bytecode, runtimes, and developer tools.
Ship a product
See shared engines, storage, UI compilation, authoring, and deployment converge into usable applications.
Live from the repository
Open the machinery.
These are working builds, not screenshots. Change inputs, inspect intermediate state, and watch the repository's packages collaborate in real time.
