After working on my book "A Year With Symfony" for four months, I published it yesterday at the Dutch Symfony Usergroup meetup in Amsterdam. It was really great to be able to do this real-time while everybody in the room was looking at the screen waiting for the build process to finish.
The book is hosted on Leanpub, which is a great platform for writing and publishing books. They provide the entire infrastructure. You get a good-looking landing page and they handle all things related to payment.
During the official presentation I briefly talked about most of the subjects that the book touches. These are the slides of this presentation:
