Ruby is a high-level, fully object-oriented programming (OOP) language. It is very powerful and relatively easy to learn, read, and maintain.

Sams Teach Yourself Ruby in 21 Days provides the best introduction to this language and addresses one of the key constraints it faces: "The paucity of quality English-language documentation is one of the few things holding Ruby back from widespread adoption," according to Dr. Curtis Clifton of Iowa State University¿s Department of Graduate Computer Science.

Great introduction to Ruby

Reviewed in the United States on February 24, 2014

Verified Purchase

This books shows things you can do with Ruby. Not only can you do programming with it, but you can control system functions as well. This book clearly shows the relationship of classes and methods. I had a vague idea what classes were until reading this book. There are many examples you can run on your own system and learn at your own pace. A great buy!

Probably great if you have time

Reviewed in the United States on July 1, 2010

Verified Purchase

I can't say a lot of good or bad about the book because I didn't get past the lesson where you program a "conversation" with an old lady. So far, I haven't had good luck learning Ruby or VBA from books or other written materials. If you have the time to spend working through this book, you might want to consider taking classes at a local college. I probably won't buy any more books about programming in general. The format and tone of the book seems very good, so if you've got 21 days with enough time to walk through the whole book, I would say go for it.

Too Dry For Me

Reviewed in the United States on August 23, 2007

Verified Purchase

This book was too dry for me. In fact, I didn't finish it. I like to open a book and look at the code examples before I buy it but, in this case, I bought it online. It seemed to me that the examples weren't very interesting and had a great deal of math in them. When I pick up a book of this type, if a lot of the examples include math examples, I don't purchase it. I am one of those people that is horrible in math and I usually don't get the examples.

Since I did not read through the entire book, I will give it 3 stars since I just don't know what is in it (besides math). I went with Programming Ruby: The Pragmatic Programmers' Guide, Second Edition version.

Again, don't take this to heart that one book is better than another. There might have been very valuable information that I missed but, when I want examples, I want real world examples that I can wrap my head around.

Useful book marred by bad editing and egregious typos

Reviewed in the United States on April 30, 2003

This book is marred by sloppy editing -- the devil is in the details. A casual reading turned up no less than five places where the meaning of illustrative materials or figures thwarted or contradicted the author's intent (and, in some cases, machine logic!) There is one diagram that was slapped onto the pasteboard and scanned to plate in an obvious hurry -- wiping out the top 8 pts of a 10 on 12 pts line of text. Aside from these pitfalls, the book has a chatty, conversational style guaranteed to drive advanced programmers from other disciplines (C, C++, Perl) up the wall. Since only advanced programmers can recognize the many errors, and only newbies will benefit from the chatty style, I can't really give this more than three stars, even though the author is obviously more proficient than SAMS' slapdash editing would indicate.

great book about Ruby

Reviewed in the United States on June 13, 2002

Ruby is a very cool and powerful language. If you find yourself frustated with old an ugly languages like C or C++ or if you are
a Perl programmer who thinks that Perl is hard to read (and it is, most of the time) than you should learn Ruby. And this book
is a very good starting point. It assumes no Ruby experience and explains all the basic of the great programming language. I found no erros in the book and the author is really an expert.

If you want to learn the more advenced features of Ruby consider
buying "The Ruby Way" and "Ruby Developers Guide" and "Programming Ruby: A Pragmatic Programmer's Guide"

I can't believe I a 21 Days book is this good!

Reviewed in the United States on February 15, 2006

I have read other books from the 21 days series some time ago and was far from impressed. But since introduction books for Ruby are limited, I reluctantly decided to give this one a try. I am happy to say I have no regrets about reading it. I am actually surprised how much I learned from it. This book really serves well anyone who is not familar with Object Oriented programming. The author has presented the chapters in good order and provides clear explanations and example code. The only problem I have with the book is the high number of typos.

Excellent Book

Reviewed in the United States on March 31, 2007

This book makes it easy to understand difficult topics in Ruby. I loved the way the authors gradually built up from a simple example and illustrated the complicated concepts. Reminds me of my favorite Electronics teacher in college.

Beginners must read this book.
