## What it is
A collection of detailed study notes on classic systems programming books (APUE, UNIX Network Programming, TCP/IP Illustrated, The Go Programming Language), published as the website notes.shichao.io. The repository contains both the Markdown source and the site build tooling for the notes.

## Use cases
- study notes for Advanced Programming in the UNIX Environment
- learn UNIX network programming from summarized notes
- understand TCP/IP Illustrated concepts chapter by chapter
- review The Go Programming Language book notes
- find explanations of sockets, signals, and threads topics
- self-host a personal technical notes site

## When to choose
- you want condensed, chapter-by-chapter notes on APUE, UNP, TCPv1, or GOPL instead of reading the full books
- you need a quick reference for UNIX systems and network programming concepts
- you want an example of publishing book-style notes as a static website

## When to avoid
- you need official, complete, or up-to-date documentation rather than personal study notes
- you expect a maintained software tool or library rather than prose content
- you need content on topics beyond the covered books (e.g., modern cloud or web development)

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: documentation, static-site-generator, markdown
- domain: tutorials, operating-systems, networking, programming-languages, developer-tools
- platform: python
- tags: study-notes, apue, unix-network-programming, tcp-ip-illustrated, gopl, book-notes, sphinx, web-server, linux
