QEMU Mac OS 9 Instructions

Here is a short guide on how to build QEMU to run Mac OS 9 with working audio. These instructions work for MacOS High Sierra as the host OS, although with some tweaking they may run under Linux/Windows. You should be comfortable compiling software from source before attempting.

Clone QEMU fork

Adapted from instructions from Cat_7

You may need to install XCode and/or the XCode command line tools. If you do not have them, then this process may prompt you to install them (MacOS will do that).

2020/5/31追記: 自分用のメモに書いていたつもりだったのですが、たくさんのスターを頂けてとても嬉しいです。
と同時に、書きかけで中途半端な状態のドキュメントをご覧いただくことになっており、大変心苦しく思っています。

このドキュメントを完成させるために、今後以下のような更新を予定しています。

TODO部分を埋める
書籍を基にした理論・原則パートと、実装例パートを分割
- 現在は4層のレイヤそれぞれごとに原則の確認→実装時の課題リスト→実装例という構成ですが、同じリポジトリへの言及箇所がバラバラになってしまう問題がありました。更新後は、実装時の課題リストを全て洗い出した後にまとめて実装を確認する構成とする予定です。

Semantic Commit Messages

See how a minor change to your commit message style can make you a better programmer.

Format: <type>(<scope>): <subject>

<scope> is optional

Example

Regular Event Loop

This shows the execution order given JavaScript's Call Stack, Event Loop, and any asynchronous APIs provided in the JS execution environment (in this example; Web APIs in a Browser environment)

Given the code

Adding and removing static host mappings on EdgeRouter

Tested on a Ubiquiti EdgeRouter 4 with dnsmasq enabled for DHCP (and DNS) serving.

These operations can also be carried out in the EdgeRouter web gui with the "DNS host names" Wizard (click the "Wizards" tab and then select "DNS host names" to access).

To see all currently statically mapped hosts:

$ cat /etc/hosts

Get the first Monday of a month (and more)

This is a small cheat sheet for PHP's strtotime function, which can be used to convert textual sentences such as "next Friday" and "last Monday" into UNIX timestamps and formatted dates.

In the examples below, I've used the format "j, d-M-Y", which will give you something like: Monday, 17-Aug-2015. You can change this to your format of choice

	GIT_TAG="$( git describe --abbrev=0 )"
	GIT_HASH="$( git rev-parse HEAD )"
	BUILD_DATE="$( date +%F )" # Note: An ldflag cannot contain whitespace

	REPO="github.com/user/repo"
	OUTPUT_NAME="build-artifact"
	PACKAGE="main.go"

	read -r -d '' LDFLAGS << EOM
	-X ${REPO}/cmd.gitVersionTag=${GIT_TAG}

	#!/bin/bash

	rm -rf /home/yen3/ubuntu.qcow2
	qemu-img create -f qcow2 /home/yen3/ubuntu.qcow2 10G

	virsh undefine ubuntu1604arm64 --nvram

	install_from_localtion() {
	virt-install -n ubuntu1604arm64 --memory 1024 --arch aarch64 --vcpus 1 \
	--disk /home/yen3/ubuntu.qcow2,device=disk,bus=virtio \
