I don't use Stripe or Rails but "Mastering Modern Payments" is something I'm very interested in. "Processing Payments with Background Workers" particularly rang home with me. We use PHP with Sagepay/Paypal so not sure how well it would benefit me? Would love something a bit more generic or indeed in more languages.
