(I tried to post this as a quote-note, but it ended up as a reply, so here we go again)

In unrelated news: I broke my BTCPay server yesterday evening, but it works again.

You can buy the e-book or printer friendly chapter PDFs directly from me. The physical book is mainly available via Amazon.

Shipping physical books is an absolute pain and - at least in the EU - a privacy nightmare for both sender and recipient. That's why I don't do it myself.

But the layout on paper is much, much nicer. I wish e-book readers supported Latex. That said, one of the downloads you get from me is a PDF optimised for the typical Kindle size, which is _much_ nicer than the epub.

I also like the idea of having many physical backups out there, in case of a future digital book burning. Despite the price being higher, I make slightly less, but that's fine.
