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?

Instructions to Update the BIOS/UEFI for an HP Laptop on Linux

To update the BIOS/UEFI firmware requires HP-specific files in the EFI System Partition, also referred to as ESP.

On a Linux system, the ESP is typically mounted on /boot/efi or /efi. Whithin you should also find a EFI directory, e.g. /boot/efi/EFI or /efi/EFI. This article assumes that the ESP is mounted on /efi and that the /efi/EFI directory exists. You can replace that with the mount point your system uses.

The HP-specific files are located in /efi/EFI/HP or /efi/EFI/Hewlet-Packard. These files typically come preinstalled in HP Windows PCs. If you have these files you could skip Install HP-specific files.

Intro and history of ML on the web

Autodraw by Google is a tool that allows you to doodle what you want to paint and turns it into a proper icon by detecting the outline and making an ML based assumption what it could be.
Quickdraw by Google is a game they created a few years before Autodraw to train the model.
ReCaptcha is a CAPTCHA engine that feeds the data back into Google's ML systems. For example, currently being asked to detect street signs or cars is a good indicator that this data will go into the self-driving cars project.

Be Careful with Table Driven Tests and `t.Parallel()`

We Gophers, love table-driven-tests, it makes our unittesting structured, and makes it easy to add different test cases with ease.

Let’s create our table driven test, for convenience, I chose to use t.Log as the test function. Notice that we don't have any assertion in this test, it is not needed to for the demonstration.

func TestTLog(t *testing.T) {
	t.Parallel()

	import type { Prettify } from 'ts-essentials';

	export type Result<T = unknown, E = unknown> = Success<T> \| Failure<E>;

	export interface Success<T> {
	kind: 'success';
	value: T;
	}

	export interface Failure<E> {

	// Types for the result object with discriminated union
	type Success<T> = {
	data: T;
	error: null;
	};

	type Failure<E> = {
	data: null;
	error: E;
	};
