I started to follow Hand Made Hero again, here is the source code from Day 5. I also formatted it with clang.
win32_handmade.cpp

This whole video is in Q&A form, which is quite enjoyable to watch.
I strongly agree with Linus in the following thoughts:

Generic programming is an important idea in programming. In languages like Java and C++, it can be done easily. In this post, I show how to do it in plain old C.
We use the classic stack implementation. First, we implement an int version.
This is stack.h:
typedef struct { int *elems; int logLength; int allocLengh; } stack; void StackNew(stack *s); void StackDispose(stack *s); void StackPush(stack *s, int value); int StackPop(stack *s); This is stack.
The operator flatmap in RxJava is a tough topic if you are not familiar with functional style.
After reading all the articles and tutorials and even worked with RxJava for almost a year, I’m still not quite confident about it. I sure know how to and when to use it, but the understanding seems always shallow.

The key is to understand the word flat.
