Title: Build Your Own Redis with C/C++
Site: build-your-own.org

 Introduction 
 
 Why build Redis?  The knowledge required is broader and deeper
than usual application-level development. It’s a good way to level up
your skills (mainly network programming and data structures). 
 Why from scratch?  A quote from Richard Feynman: “What I
cannot create, I do not understand”. Human understandings are filled
with holes aka “things I don’t know I don’t know”. Building from scratch
is a way to ensure your understanding is complete. 
 Why C?  C is widely used in system programming and
infrastructure software. Learn how C is used in real projects, with
straightforward C code. No prior C/C++ experience is required. 
 Why a book?  The Redis project is a complex software system
built with lots of effort, which can be harder to grasp for beginners.
The book breaks down the core concepts into easy-to-digest steps.
