You know, I read books on ColdFusion all the time (I fly a lot) to stay up to par with things, but mostly to get different perspectives on how people see and use ColdFusion in their own lives. We all have our own perspective and uses; and I like to see how others use it and/or teach it.. (the teach it part intrigues me, because I teach it too.. so i do my best to learn from others and see what works and what doesn't so I can do it better myself).
Recently, I got my hands on a copy of John Farrar's [ColdFusion 8 Developer Tutorial] and I have to say.. I think it's clearly written...it covers a broad range of subjects, but I think what I like the most is that it goes above and beyond most books. He clearly focuses on the readers and does everything possible to get you to get it... (if that makes sense).
I am not one to recommend books, I think tutorials and "demonstrations" work better when it comes to learning things, but I think that this book can teach people quite a bit and really get them to understand and master the coding logic that is needed to become a good developer.
If you have yet to read this book, I suggest you pick up a copy.. It's not only worth the cash.. but will also be a good reference later on.. Lots of Ajax in there too.. which I haven't seen in many other books (other than WACK... but that is another story!).
Overall, I would give this book a 4.5 (out of 5 stars) because it delivers a good range of topics, clear communication, and most importantly it helps with next steps!
Great Job John!
Keep them coming!
