I started to sell the pre-release version

So I finally started to sell the pre-release of the book on Gumroad. The pre-release includes first 13 chapters that takes you from a high level overview of the whole deployment process to automating deployment of static sites. The focus of this first part of the book is on networking, system administration and automation, and security hardening in terms of SSH, SSL/TLS, and firewalls.

Selling pre-release is always a question, but honestly the last programming book I bough myself was also just an unfinished beta. And I even had this question as part of my early poll. People do want to start reading sooner! No, not everybody, but I think it's a good idea to start getting it out there, especially since it's a big book and so the pre-release is almost a book on its own.

I sent the option to buy it to the mailing list of 611 subscribers.
