## What it is
An open-source introductory systems programming textbook written in LaTeX and used for CS 341 at the University of Illinois Urbana-Champaign. It covers C and Linux/POSIX systems programming and is published as PDF, HTML, EPUB, and wiki formats.

## Use cases
- learn systems programming in C on Linux
- study POSIX APIs like processes, threads, and signals
- find a free operating systems course textbook
- prepare for a university systems programming course
- reference Linux system programming concepts like memory and file systems
- contribute to or fork an open systems programming book

## When to choose
- you want a free, rigorous introduction to C systems programming on Linux
- you are a student or instructor of an OS or systems programming course
- you prefer textbook material with citations, glossary, and multiple export formats

## When to avoid
- you need a hands-on tool or library rather than reading material
- you are a complete beginner without prior programming or assembly exposure
- you need Windows or macOS systems programming content

## Facets
- artifact type: learning-resource
- maturity: active
- function: documentation, markdown
- domain: operating-systems, education, developer-tools, tutorials
- platform: cli
- tags: textbook, systems-programming, c, posix, latex, wikibook, open-courseware, linux
