Great tutorial, technical level and writing rhythm are just perfect (for me at least). Feels great to read something written with care that doesn't sound like yet another Claude-generated blog post.

Here I was thinking it was a book about Jujutsu. I don't use the noncombat version but for what it's worth, this seems well written. So kudos to the author.

Having a read through and so far enjoying the cadence and pacing. Just wanted to note, before I forget, that there is a typo @ https://arialdo.codeberg.page/ju-ju-tsu/preface/at-a-glance.... Impatietn —> Impatient

I've tried JJ multiple times, but always tapped out after a day. Having to work with raw SHA1 hashes is so utterly tedious and I never quite figured out how to... just use it in normal day to day work. The book looks well done and a labor of love, but the #1 issue Git users have, merge conflicts, isn't discussed until chapter 13 (reminds me of a Neovim tutorial I read recently where "editing text" isn't until chapter 6).
