A collection of computer science study notes organized as XMind mind maps, covering Linux, networking, C++, Golang, databases (MySQL/InnoDB), distributed systems, middleware, and Kubernetes. It provides both .xmind source files and exported PDFs for each topic.
Use cases
- review operating system fundamentals like CFS scheduling and POSIX condition variables
- study how MySQL InnoDB indexes, MVCC, and replication work
- prepare for backend engineering interviews on TCP, epoll, and Linux network programming
- learn Golang and C++ core concepts through structured mind maps
- understand distributed systems and middleware design basics
- download xmind files to build a personal CS knowledge base
When to choose
- you prefer visual, mind-map style notes over long articles
- you want curated deep-dives into MySQL internals, Linux, and networking fundamentals
- you are preparing for backend/systems interviews and want concise structured review material
When to avoid
- you need executable code or tools rather than study notes
- you need up-to-date content, as the latest release was in 2022
- you require a license permitting redistribution of the material
