@masukomi@Covok not 'github' - git. I'm using it as the decentralised service it was intended to be. It's on half a dozen sites, and if they all die, developers with a copy can put it up again, and a new QR is born.
Of course, a PDF with the book would be better, but it won't update when the basilisks hibernate, so you may as well use the tables in the book.
