The Camel book is probably my most used programming reference. It has gotten to the point where I can astound and amaze my coworkers by opening it to exactly the right page on a particular topic. For the past two days I've been using the 3rd edition (three-hump camel?) and I feel like I came home to find all my furniture glued to the ceiling. Everythings in the wrong place!
Not a complaint really, just a bemused and bewildered observation.
