CS-Notes is a GitHub repository maintained by CyC2018 that collects Chinese-language study notes across ten topic areas: algorithms, operating systems, networking, object-oriented design, databases, Java, system design, tools, coding practice, and an afterword. It links each topic to standalone markdown files instead of writing everything inline, and the README says most of the content is original work rather than material copied from elsewhere.

Java Design Patterns is an open-source GitHub project by iluwatar that documents design patterns as commented, working Java code rather than diagrams or prose. The repository has 94,590 stars and is organized so readers can find a pattern by name, by tag such as Gang of Four or Performance, or by category, with a companion site and an optional paid e-book alongside it.
