QEMU with VirtIO GPU Vulkan Support

With its latest reales qemu added the Venus patches so that virtio-gpu now support venus encapsulation for vulkan. This is one more piece to the puzzle towards full Vulkan support.

An outdated blog post on clollabora described in 2021 how to enable 3D acceleration of Vulkan applications in QEMU through the Venus experimental Vulkan driver for VirtIO-GPU with a local development environment. Following up on the outdated write up, this is how its done today.

Arch Installation Guide for Total Beginners

Guide by anna328p/alienpirate5.

This is meant as a companion for the official Arch install guide: https://wiki.archlinux.org/index.php/Installation_guide

This document is a guide for installing Arch Linux from the live system booted with the official installation image.

This document will walk you through the Arch Linux installation process based on the Arch Wiki installation guide. You will need to refer to the wiki for links; this guide just explains the steps in more detail. Keep in mind that this

Okay, I've got a need to build Firefox from source, and I'd like to do that on a remote machine, and then copy build result back to my laptop. With Nix, using bastion host. I'll note details of my successful adventure.

Setup & Sources of knowledge

Here's the list of resources I've used actively:

https://nixos.wiki/wiki/Distributed_build
https://nixos.org/nix/manual/#conf-trusted-substituters and various other configuration parameters
https://github.com/NixOS/nixpkgs/blob/release-19.09/nixos/modules/services/misc/nix-daemon.nix which contains mappings from Nix config names to NixOS config names (damn, they are different!)

Here's my setup:

	/* Protonmail cleanup scripts
	* Works with ProtonMail v4.0.14 as of 2022-01-23
	*
	* Based on Lyndsy's Protonmail mass archiver:
	* https://gist.github.com/lyndsysimon/e6a4a1becaddf09fe02c503793b545d6
	*
	* Usage:
	* - Navigate to your inbox (or another folder/label, presumably)
	* - Open your browser's developer tools' Javascript console
	* - Paste in this script

	minimod: A stripped down module system

	TODO Comparison:
	- [ ] Come up with a benchmark "logic" using plain old functions and let bindings
	- [ ] Write the benchmark for the module system
	- [ ] Write the benchmark for POP?
	- [ ] Qualitative comparison of extensibility in the context of composable
	Nixpkgs packaging logic
	TODO Fine-tuning:

	#!/usr/bin/env bash

	# shellcheck disable=SC2034
	COMMIT_MSG_FILE=$1 # file which contains the commmit message
	# shellcheck disable=SC2034
	COMMIT_SOURCE=$2 # eg commit
	# shellcheck disable=SC2034
	SHA1=$3 # eg head

	perl -i -ne 'print unless(m/^. Please enter the commit message/..m/^#$/)' "$COMMIT_MSG_FILE"

	#!/bin/bash
	set -eu

	usage() {
	cat >&2 <<'EOF'
	usage: ./difflog $out1 $out2

	Compare two Nix build logs, normalizing out boring differences.

	This can be useful to test the effect of a change to build scripts,

	{ config, pkgs, lib, ... }: {
	imports = [
	(import <nixpkgs/nixos/modules/system/etc/etc.nix>)
	];

	options.system.build.etc = lib.mkOption { type = lib.types.package; };
	options.system.activationScripts.etc =
	lib.mkOption { type = lib.types.unspecified; };

	config = {

	use std::str;

	fn main() {
	// -- FROM: vec of chars --
	let src1: Vec<char> = vec!['j','{','"','i','m','m','y','"','}'];
	// to String
	let string1: String = src1.iter().collect::<String>();
	// to str
	let str1: &str = &src1.iter().collect::<String>();
	// to vec of byte
