Atomic Scala is now “in production,” which means we’re building the index and finalizing the cover and making editing passes and creating other support elements so we can actually go to press in a month or so. We’ll stay with print-on-demand for the time being because we’re still learning things and want the freedom to make improvements. This book is also an attempt to adjust to the way that people actually learn and to make that learning experience better — this makes it more of a continuous experiment. For example, a few weeks ago my coauthor and I gave a one-day tutorial at a conference, and we came away realizing that experienced programmers needed a couple of summary chapters that they could jump to; this way the book can serve both beginning programmers and experienced programmers. So we came back and wrote those, and now the book is better. We expect this experience will be repeated as we gain more information about how people learn from the book.
