学 C 语言学到指针还行，一碰到进程、线程、锁这些操作系统的东西，课本讲得干巴巴，网上资料又东一块西一块。

伊利诺伊大学的系统编程课 CS 341，把自己用的课本开源了，就叫 Coursebook。

内容从 C 语言入门讲起，一路讲到进程、内存分配、线程、同步与死锁、进程间通信、调度、网络、文件系统、信号和安全，代码全部用 C 写。

前身是一份公开的 wiki 教材，现在补上了引用、脚注和术语表，书后还附了复习题。

GitHub：https://t.co/VoXkeBKAy1

网页版可以直接在线读，也有 PDF 和 EPUB，下载下来放进阅读器里看。

先学过一门编程语言、对汇编有点了解再看会比较顺。正在学操作系统、或者想补补底层功底的朋友，拿它当教材挺合适。

[Shalini Goyal @goyalshaliniuk]

Networking is everywhere.

Every API call, page load, database request, and real-time message depends on a few core networking concepts working together.

Here are 8 concepts every developer should understand:

→ 𝗗𝗡𝗦 𝗥𝗲𝘀𝗼𝗹𝘂𝘁𝗶𝗼𝗻
Converts domain names into IP addresses so clients can find the correct server.

→ 𝗛𝗧𝗧𝗣 / 𝗛𝗧𝗧𝗣𝗦
Handles web communication through methods, headers, status codes, and secure TLS transport.

→ 𝗧𝗖𝗣 𝘃𝘀 𝗨𝗗𝗣
TCP focuses on reliable, ordered delivery. UDP prioritizes speed, low latency, and minimal overhead.

→ 𝗥𝗘𝗦𝗧, 𝗚𝗿𝗮𝗽𝗵𝗤𝗟 & 𝗴𝗥𝗣𝗖
Each API style offers different trade-offs around simplicity, flexibility, typing, and performance.

→ 𝗪𝗲𝗯𝗦𝗼𝗰𝗸𝗲𝘁𝘀
Create persistent two-way connections for chat, live dashboards, collaboration, and real-time applications.

→ 𝗧𝗟𝗦 & 𝗘𝗻𝗰𝗿𝘆𝗽𝘁𝗶𝗼𝗻
Protect data in transit through authentication, encryption, session keys, and integrity checks.

→ 𝗥𝗲𝘃𝗲𝗿𝘀𝗲 𝗣𝗿𝗼𝘅𝗶𝗲𝘀
Handle routing, caching, TLS termination, rate limiting, and load balancing before traffic reaches backend services.

→ ��𝗼𝗻𝗻𝗲𝗰𝘁𝗶𝗼𝗻 𝗠𝗮𝗻𝗮𝗴𝗲𝗺𝗲𝗻𝘁
Uses pooling, keep-alive, timeouts, and backpressure to reduce latency and improve throughput.

You do not need to become a network engineer to write better software.

But understanding how requests actually move across a network makes APIs, backend systems, distributed applications, and cloud architecture much easier to design and debug.

Which networking concept took you the longest to understand?

P.S. Preparing for a software engineering role? Check out my book, System Design and Behavioral Intelligence.
It will help you:

•⁠ ⁠Build strong System Design foundations and approach design problems with confidence
•⁠ ⁠Develop practical frameworks to navigate complex behavioral and leadership challenges
