What is this?
CodeGuide is a personal knowledge hub by Chinese Java engineer Fu Zheng Wei (小傅哥) that indexes years of his work: an interview handbook, hand-rolled clones of Spring and MyBatis, a JVM written in Java, Netty tutorials, bytecode-programming guides, and a published design-patterns book, all centered on core Java development.
