Show HN: I just finished my landing page for my Data Analysis with Rust book

> Show HN is for something you've made that other people can play with. HN users can try it out, give you feedback, and ask questions in the thread.

> Blog posts, sign-up pages, curated lists, and other reading material can't be tried out, so can't be Show HNs.

This doesn't look like something we can try. It's not clear how this rule applies to books, but in an old thread, dang said that a sample chapter may be enough.
