But I found Programming Ruby to be an excellent starting point -- it provides the quick-start help I need by giving numerous and well thought-out examples both in the body of the text and in the reference section (see below).
The chapters are well arranged (and even include information on distributed Ruby on page 272, often where most texts just start talking about file I/O!), with the first 276 pages devoted to an introduction to the language. The last 250-or-so pages contain an excellent library reference, alphabetically arranged.
The devil is in the details, though. And here, AW put a lot of thought into the finer points. The type is clear; the typographic conventions are standard and, if you've used any other typical programmer's text, easy to follow. So far, this is what you'd expect from any good computer title. In addition, however, they have added an easy-to-use thumbtab system for the alphabetical arrangement of the reference section, so finding a particular entry is quick and easy. Each entry in the reference section is clearly laid out with a class hierarchy (including super- and subclasses), parameters, description, "Mixes in" and a list of all class methods (most (if not all) with examples and output. All well-designed not only for the experienced Ruby programmer but also for the novice.
The index is thorough, with helpful vertical lines between the columns, and the reference section entry is identified by bold page numbers.
All in all, I would highly recommend this book for new Ruby programmers. There are still a number of things I don't understand about Ruby, but this book is an excellent place to start. It sets the bar very high for future books on this new and exciting programming language.

Not only does the book have an excellent tutorial which goes over major Ruby concepts and the majority of the language you will encounter on a daily basis, but it also has an indispensable language and standard library reference, as well as an overview of the C API and details on the inner workings of the Ruby interpreter.
This book is definitely worth picking up if you want to start dabbling in Ruby, and is almost a requirement to have on your desk during heavy hacking sessions.

As an online statistics tutor, I find myself referring to it all the time. It has all of the topics that are normally covered in a first course in statistics. It also has some very good chapters on elective topics such as nonparametrics, sample surveys, and quality control. I took many courses in these subjects in undergraduate and graduate school, and I find that this book is a good review for some of the things I've forgotten.
I have many statistics books both elementary and advanced. This is one of only two elementary books that I would purchase again (my teacher's edition is losing the binding!).
It is probably the most complete book on statistics that I have ever read at this level. I would certainly recommend this book to anybody who is taking statistics for the first time. I would also recommend this book to statistics majors who plan to go into teaching and need a good review text.

This book was puchased midway through the semester. At that time I was struggling to maintain a C average. With the help of this book I was able to close the semester with an 89% average.
