I wrote Programming Bitcoin for O'Reilly and it was published 3 years ago. Some observations: * You won't make that much money directly, but I have probably made a good amount indirectly. The credibility from having published an O'Reilly book is not to be underestimated. * I got the animal I wanted (honey badger) by asking for it. I did justify the ask by showing my editor the Bitcoin honeybadger memes. * The book writing process was a grind. Because my book was so focused on programming exercises, I wrote my own suite of testing tools to make sure everything was consistent. It felt more like a software engineering project than a bunch of blog posts. * I have since introduced more people to my intake editor and they've published their own O'Reilly books. * I don't get much of a discount on my own book. I just buy them through Amazon. * They give you a framed picture of your cover when your book publishes.
