What coursebook does

This repository hosts a high-quality, open-source coursebook used for CS 341: System Programming at the University of Illinois Urbana-Champaign. It serves as a comprehensive textbook covering core systems concepts, assuming prior knowledge of basic programming and assembly. All code examples and instruction are written in C, utilizing the POSIX standard since it is the de-facto language of the Linux kernel. The project is maintained as a collaborative wikibook, allowing for continuous updates and improvements from educators and students alike. It provides a deep dive into operating system fundamentals and low-level software design.

Computer science students, specifically those at UIUC, and independent learners looking to understand low-level systems programming. It requires prior familiarity with a programming language and basic assembly instructions.

  • Comprehensive curriculum: Covers core introductory systems programming concepts taught at a university level.
  • C and POSIX focus: Centers all instruction and code examples around C and the POSIX API.
  • Open-source wikibook: Allows for community contributions, corrections, and continuous educational improvement.
  • LaTeX formatting: Utilizes LaTeX for professional, high-quality typesetting of the textbook material.
  • Practical examples: Includes actionable code snippets that demonstrate low-level Linux interactions.

Where teams use it

University instruction

Serves as the primary reading material for students enrolled in UIUC's CS 341 course.

Self-teaching systems programming

Provides a structured, high-quality resource for independent learners wanting to master C and POSIX.

Reference for C developers

Acts as a detailed guide on low-level system calls, memory management, and Linux kernel concepts.

Curriculum development

Offers a template and resource for other educators building their own systems programming courses.

Welcome to the systems programming coursebook! This repository houses a high-quality, open-source introductory systems programming textbook used by the CS 341: System Programming course at the University of Illinois Urbana-Champaign The book assumes that you have taken a programming language course and are familiar with assembly instructions. All of the code and instruction will be in C, as it is the de-facto language of the Linux Kernel.

The Coursebook is an aim to standardize and build upon Angrave's original wikibook experiment.

The most recent version of the coursebook as a single pdf is here: main.pdf.

Overview

Goals

  • Improve the quality and rigour of the original wikibook while maintaining openness.
  • Improve the factualness by including citations, footnotes, extended reading, and a glossary.
  • Have exports in the form of pdf, markdown, and html.
  • Automagically build so writers can focus on writing.
