Ubuntu 21.04 VM with GPU acceleration under Hyper-V...?

Modern versions of Windows support GPU paravirtualization in Hyper-V with normal consumer graphics cards. This is used e.g. for graphics acceleration in Windows Sandbox, as well as WSLg. In some cases, it may be useful to create a normal VM with GPU acceleration using this feature, but this is not officially supported. People already figured out how to do it with Windows guests though, so why not do the same with Linux? It should be easy given that WSLg is open source and reasonably well documented, right?

Well... not quite. I managed to get it to run... but not well.

How to do it?

Verify driver support

You have to do 2 things in order to allow your container to access your host's postgresql database

Make your postgresql listen to an external ip address
Let this client ip (your docker container) access your postgresql database with a given user

Obs: By "Host" here I mean "the server where docker is running on".

Make your postgresql listen to an external ip address

Find your postgresql.conf (in case you don't know where it is)

$ sudo find / -type f -name postgresql.conf

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
