What is this?
This is a free, illustrated Chinese guide to core computer science fundamentals - computer networking, operating systems, computer organization, and databases - built from over 1,000 diagrams and 500,000+ words, aimed at making notoriously dry CS topics (and common interview questions) actually understandable.

It targets developers and students preparing for technical interviews or trying to finally understand CS fundamentals, since the author explicitly frames it as an antidote to rote-memorized interview answers ('八股文').What does the mention of 八股文 (bagu) mean here?It refers to the formulaic, memorized technical interview answers common in Chinese tech hiring; the author wants readers to actually understand the concepts instead of reciting canned answers.

Yes, the README links to downloadable PDF versions of the Networking (图解网络) and Operating Systems (图解系统) guides.Does it cover MySQL and Redis internals too?Yes, dedicated sections cover MySQL indexing, transactions, locks, and logging, plus Redis data structures, persistence, replication, and cache consistency issues like cache avalanche and breakdown.
