I am constantly amazed (and humbled) by the generosity of time experts in this field of very, very busy people continue to demonstrate over and over again. I don’t know if other professions are the same way, but it really makes this one a pleasure to work in. Here is a free e-book by Karl Seguin of CodeBetter.com. I haven’t read it yet, but I very much look forward to it. From the TOC it looks like it will be a very useful resource.
