CentOS 7 Kickstart File - HOWTO Build ISO

There is so much documentation online from RedHat and CentOS about this topic - it's sad that I am writing this. But the real state of documentation on this topic (CentOS 7 + KS + ISO = Bootable DVD) is almost non-existent.

I found this: http://smorgasbork.com/component/content/article/35-linux/151-building-a-custom-centos-7-kickstart-disc-part-1

Which I greatly appreciate and +1, but the documentation is half-baked and there are numerous errors.

Finally... FINALLY! After four days of banging my head, I got this to work. Hopefully someone else will be able to do this in a few hours, instead of blowing their weekend like me. :(

Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](https://www.amazon.de/Large-Scale-Soft

Futures 0.3 and Async/Await

This document will try to give a short tutorial of how to use the new style futures (0.3), how to use Async/Await, and how to use the compatibility layer to interoperate with old futures (0.1) and tokio.

Terminology

When dealing with futures in this new world there are a lot of different parts and it can be difficult to keep things straight at times. As such here is a quick run down of the different parts and what they are.

	#include <stdio.h>
	#include <stdlib.h>
	#include <assert.h>

	typedef unsigned int u32;
	typedef unsigned long long u64;

	void __wrap_memcpy(void dest, const void *src, size_t n)
	{
	return __memcpy_glibc_2_2_5(dest, src, n);
	}
