My 2-Year College Notes Hub — enjoy the journey of exploring X
X-Plore is one person's two-year self-study log reformatted as a GitHub repo: a huge linked table of contents pointing to CSDN blog posts where they walk through the source code of other projects (nanoGPT, nano-vllm, RAG pipelines, Qlib, Sora, etc.). It isn't a library or tool you install — it's a reading index for a Chinese-speaking developer who wants pointers into how real AI/systems codebases work, written by someone who actually read the code.
The notes are source-level, not landing-page fluff — entries name actual classes and functions (nano-vllm's LLMEngine.step, nanoGPT's CausalSelfAttention, RE2's DFA::RunStateOnByte), which only comes from reading the code. scripts/generate_repo_index.py and enrich_cn_index.py show they automated the giant index table instead of hand-editing 300+ markdown rows, which is the only reason this scaled past a dozen entries. repo/github_repos.csv is a genuinely reusable byproduct — a structured list of ~100+ repos someone judged worth reading through, independent of the notes themselves.
All the actual content lives off-repo on a personal CSDN blog account — the repo itself is just an index of links, so note quality, depth, and even availability depend entirely on a third-party Chinese blog platform staying up and that account staying active. The README is one unbroken wall of ~80 topic anchors with no indication of which notes are deep dives versus a single paragraph, so you can't tell what you're clicking into until you click. There's no license file, which matters less for notes but makes the repo/github_repos.csv dataset and the index-generation scripts legally ambiguous to reuse. Nearly everything is Chinese-language and Chinese-platform-hosted (CSDN, Xiaohongshu, Bilibili), so despite English section headers in the table of contents, this is only genuinely useful if you read Chinese.
