Oh I did not pick up on that, thanks. No Starch are pretty nice nice pressings though so might be worth it. Cheers.

One of two authors here!

Here's the situation: No Starch, being as awesome as they are, are totally happy with printing an open-source book. The Rust project wanted to do a second edition of the book for various reasons, so Carol and I have been doing that, but also, working with No Starch's editors. So they've been collaborating with us on it. It also means you can get a nicely laid out eBook, the paper copy, all of that.

The proceeds are going to charity.
