Choose a fork to inspect
Prefer upstream unless you specifically want an older, heavily edited fork to use as a customization base or archival snapshot. This fork is not a good choice for adopters who need current coverage and ongoing maintenance.
Choose this fork only if its narrower Linux/MySQL and Chinese/English focus matches your use case; otherwise upstream is the better default because it is far more current, broader, and actively maintained.
Prefer this fork only if you need its 2019 snapshot or its customized structure. For anyone who wants the latest, maintained programming-resource catalog, upstream is the better choice.
Choose this fork only if you specifically want an old, mostly frozen copy to customize or archive. If you want current free-learning resources, upstream is the better default because it is actively maintained and materially newer.
