FAQ on the xz-utils backdoor (CVE-2024-3094)

This is a living document. Everything in this document is made in good faith of being accurate, but like I just said; we don't yet know everything about what's going on.

Update: I've disabled comments as of 2025-01-26 to avoid everyone having notifications for something a year on if someone wants to suggest a correction. Folks are free to email to suggest corrections still, of course.

How to set up QEMU working properly on M1 Mac

Last-Update: June 8, 2021.

This document describes how to run Windows 10 for ARM and Linux operating systems properly on Apple Silicon (M1) Mac by using open source software only. The combination of [QEMU] and [Alexander Graf's Hypervisor.framework support patch][Alexander Graf's patch] allows us to run Windows 10 and Linux for 64-bit ARM processors on M1 Mac efficiently. Several webpages such as [How to run Windows 10 on ARM or Ubuntu for ARM64 in QEMU on Apple Silicon Mac] and [QEMU on M1 Mac] describe how to set up a QEMU environment with Alex's patch. While they are helpful for the first trial, additional effort is needed to realize a proper QEMU environment that can be used for our daily business.

これは結城浩さんの運用されていた YukiWiki に当時 Coffee 様 (青い鴉（ぶるくろ）さん）がかかれていた文章です。 ただ 2018 年 3 月 7 日に YukiWiki が運用停止したため消えてしまいました。その記事のバックアップです。

今は 404 ですが、もともとの記事の URL は http://www.hyuki.com/yukiwiki/wiki.cgi?%A5%C7%A5%B9%A5%DE%A1%BC%A5%C1%A4%AC%B5%AF%A4%AD%A4%EB%CD%FD%CD%B3 になります。

昔、自分がとても感銘を受けた文章なので、このまま読めなくなるのはとてももったいないと思い、バックアップとして公開しています。
