## What it is
An open-source technical explainer (published at cpu.land) by Lexi Mattick and Hack Club that walks through how a computer runs programs from start to finish. It covers CPU basics, system calls, memory, ELF executables, linking, and fork/exec multiprocessing in a long-form illustrated article format.

## Use cases
- understand what happens when you run a program on Linux
- learn how system calls actually work
- understand how multiprocessing and fork work
- learn how the Linux kernel loads ELF executables
- self-study low-level systems concepts without a CS degree
- find a comprehensive explainer of CPU architecture and memory management

## When to choose
- you want a single cohesive narrative explaining program execution from startup to process
- you're a self-taught developer filling gaps in low-level systems knowledge
- you prefer long-form illustrated articles over fragmented documentation

## When to avoid
- you need hands-on exercises or runnable code tutorials
- you need OS-agnostic or Windows/macOS-specific coverage, since it focuses on Linux
- you need a formal textbook-style reference with citations

## Facets
- artifact type: learning-resource
- maturity: stable
- function: documentation
- domain: operating-systems, tutorials, developer-tools
- platform: -
- tags: cpu, operating-systems, elf, syscalls, multiprocessing, technical-explainer, mdx, linux, web
