What do people build with it?

USE CASE 1

Use the algorithm and Leetcode-solution notes as a structured study guide before a software engineering interview.

USE CASE 2

Review the system design chapter on distributed systems, caching, and message queues to prepare for senior engineering interviews.

USE CASE 3

Brush up on Java concurrency and JVM internals using the dedicated Java section ahead of a backend interview.

USE CASE 4

Study networking and HTTP fundamentals using the networking notes before a backend or infrastructure interview.

In plain English

CS-Notes is a Chinese-language collection of computer science study notes aimed at people preparing for technical interviews. The repository's description frames it as essential foundational knowledge covering algorithms and Leetcode-style problems, computer operating systems, computer networks, and system design. The topics tags echo this scope: algorithm, computer-science, cpp, interview, java, leetcode, python, and system-design. It works by organizing notes as a set of categorized markdown documents you can read directly on GitHub or through a companion online reading site. The table of contents groups material into sections including algorithms (with dedicated guides for "Sword Pointing to Offer" problems and Leetcode solutions), operating systems (general OS plus Linux), networking (computer networks plus HTTP and Socket notes), databases (SQL syntax and practice, MySQL, Redis), Java (basics, containers, concurrency, virtual machine, I/O), system design (distributed systems, clusters, caching, message queues), object-oriented thinking and design patterns, tools (Git, Docker, build tools, regular expressions), and coding practice. You'd use this if you're preparing for software engineering interviews, particularly in a Chinese-speaking context, and want a curated study reference covering topics commonly tested. The content is original notes by the author, with some quoted material cited in references. The license is Creative Commons Attribution-NonCommercial-ShareAlike 4.0. The repo isn't a software project, it's a study guide written primarily as Markdown notes.

Copy-paste prompts

Prompt 1

Summarize the key system design concepts from the CS-Notes distributed systems section that come up most often in senior SWE interviews.

Prompt 2

Using the CS-Notes Redis section as context, explain the difference between RDB and AOF persistence modes in plain English.

Prompt 3

I'm preparing for a Java backend interview. Based on the CS-Notes Java concurrency section, list the 10 most important concepts I need to know.

Prompt 4

Walk me through the CS-Notes explanation of the TCP three-way handshake and suggest follow-up questions an interviewer is likely to ask.
