QEMU and HVF
# Summary
A few notes I took to see if I could use MacOS as Hypevirsor in a similar fashion to Linux
I wanted to see how few addons were needed instead of using Parallels, Virtual Box, VM Fsion etc.
The idea is to use QEMU, Hypervisor Framework (https://developer.apple.com/documentation/hypervisor) and some custom host networking.
# Installations
brew install qemu (For controlling Hypervisor Framework)
brew install cdrtools (For making cloud init iso's)
http://tuntaposx.sourceforge.net/download.xhtml (For customer tap based networking)

Effective Modern CMake

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

Debugging in JRuby

Step-by-step debugging and stack navigation for JRuby code.

Problem: the common tools byebug and pry-byebug are MRI-only.

Prerequisites

Force JRuby to run in fully interpreted mode:

ld – Wading through Mac OS X linker hell

Intro

Friend: I tried looking at static linking in Mac OS X and it seems nearly impossible. Take a look at this http://stackoverflow.com/a/3801032

Me: I have no idea what that -static flag does, but I'm pretty sure that's not how you link to a library. Let me RTFM a bit.

Minutes later...
