I mentioned this book previously, but due to a delay in publishing I got the timing wrong. Now this book is on the shelves and you can buy it from your local shop, or online from No Starch, Amazon or eBay. I bought the PDF version from No Starch but then was unable to download it after dozens of attempts. As luck would have it, I found it on the shelves of a department store (not even the book stores had it) and bought a physical copy too. Naturally, I tried the PDF download one more time and it worked :)
