I feel like it's good to note since I missed it. This post is from Feb 13, 2023. He has up to 8 posts on this at this point which don't appear to be linked to from this post. I think linking to all of them would be a bit much, but they're all currently listed on his main page [1].

There’s a relevant book from No Starch, highly recommend. The author also has a series of blog posts on the topic.
