Un bon livre à avoir dans sa bibliothèque comme référence Ruby.

Je recommande fortement de l'avoir pour ceux qui souhaite apprendre Ruby sérieusement.

J'ai un peine ouvert le livre et je constate que la reliure ne tient pas. Je vais bientôt commencer à perdre des pages.

HASH(0x93d91a14) étoiles sur 5 The Definitive Ruby Resource 18 juillet 2013
Par Financial Reader - Publié sur Amazon.com
Format: Broché
This is a great, updated version of the now-classic Programming Ruby series from The Pragmatic Programmers. The book is a great reference covering the whole of ruby and many related features. This is the only current Ruby book that attempts to cover everything Ruby. The book is very well organized with topics in outline-form subsections making it easy to pinpoint one's exact learning or reference needs.

Programming Ruby 1.9 & 2.0 reads a lot like O'Reilly's "Definitive Guide" series but is also as usable as a "In a Nutshell" series reference book. I'm very impressed by the way the authors were able to write a detailed but concise (as concise as a huge language like Ruby can be anyway) programming book.

HASH(0x93fc26d8) étoiles sur 5 This edition has lost what made the original Pickaxe so great: focus, audience, narrative. 20 mars 2015
Par Michael G Schwern - Publié sur Amazon.com
Format: Broché
This edition has lost what made the original edition so great: focus, audience, narrative.

The original Programming Ruby, "the Pickaxe book" is a masterpiece. It conveyed the essence of what made Ruby such an amazing language. It read like a story, using as much detail as necessary to continue the narrative, and no more. It was, in short, very pragmatic. After reading Programming Ruby back when it came out, I felt confident I could do a lot of work in the language, and the rest I could look up. It was a book I could hand to non-programmers and experienced programmers alike.

This edition has lost the narrative and its audience. It reads more like a traditional programming language book organized by feature sets rather than building up an understanding. It makes the mistake of trying to convey too much detail before the reader is ready for it. As an example, there is an extensive diversion in chapter 4 about implementing Enumerators. The reader has just been introduced to the concept of Arrays and Hashes and is not ready for that level of detail. The author does this a lot, going off on detailed technical tangents about new features in Ruby 1.9 and 2.0. Even as an experienced programmer I find myself having difficulty following them sometimes, or understanding why its relevant, a non-programmer would have no hope.

The book will occasionally promote some very powerful, but very questionable, techniques. These techniques often come too early in the book when the reader is supposed to be learning the basics. A reader new to programming would not be able to recognize this is not something to be done in practice. For example, in the section on benchmarking and profiling, the author "optimizes" a program which reads files line by line by slurping the whole file into memory. There is no discussion of why this is a bad idea.

The book regularly assumes the reader is already familiar with programming, and Ruby/Perl like constructs. This greatly changes the nature of the book from a practical introduction to programming in Ruby, to a review of the language for non-Ruby programmers.

If you want to learn Ruby, buy the original edition or read it online. If you want information about the latest Ruby 1.9 and 2.0 features, buy this perhaps for review, or read about them online.

HASH(0x9543902c) étoiles sur 5 Books to have 27 février 2014
Par W. Mattingly - Publié sur Amazon.com
Format: Broché Achat vérifié
This book is centered around snippet code so if you are looking for a cookbook start to finish project book this is not for you. The good side of this story is I have it loaded on my work computer. When I have syntax issues I simply perform a find on the subject. this has proven to be a very productive when working. Between stackoverflow the open community web source, and this book when coding I solve problems quickly. I am a professional Ruby / Ruby on Rails developer. For all those who just know Ruby on Rails you should really learn Ruby. What happens if one of your gems does not work? or gets monkey patched? or just doesn't work? You will be forced to dig deeper and you will need to know Ruby to sort out the R-on-R MVC framework guts.

Trust me I tried just learning Rails years ago, now I know Ruby I am very seldom defeated. If you like this comment get the book GREAT resource.

HASH(0x93f2239c) étoiles sur 5 A very thorough book that helped me get started with Ruby. 17 juillet 2014
Par Colin Sulin - Publié sur Amazon.com

I needed to learn Ruby in hurry, as there was an urgent need to rewrite a module that was giving trouble in Perl because of a problematic CPAN module. This book gave me all I needed to quickly learn the language and rewrite the module in Ruby.

HASH(0x93f24108) étoiles sur 5 Not good for explaining the code 2 octobre 2013
Par Wayne - Publié sur Amazon.com
Format: Broché Achat vérifié
I've only gotten through the first 3 chapters of the book and find that the author doesn't hold my attention much. He seems more to be trying to impress me with his knowledge of the English language and of Ruby than in teaching me the basics and building on it from there. I'm not a programmer by trade, but I've programmed in C/C++, Perl, VB before. The authors style is not the way I would rather have it taught. When you teach someone something, don't use big words when a simpler one is available. There is no reason to fight to understand the language before getting to the actual knowledge being imparted below it. It's like deciphering a riddle before you can get to the meat of the sentence.

I had a much easier time reading a higher level programming book called "Eloquent Ruby" as he described why Ruby coders do things the way they do it and he said it wasn't for beginners. There were a lot of "Aha" moments when I read that. With "Programming Ruby 1.0 & 2.0", I'm like "WTF are you trying to say?" I was hoping for a beginner book to make sure I rounded out the basics of the language by getting this book. Fail!

Ruby is different and has a clearly unique style for programming. However, without hitting the basics of the reasons to use a 'puts' statement over a 'p' statement over a 'printf' statement leaves the reader confused. I have given him 3 stars because I'm hopeful that this book has the information I'm looking for. The end has a lot of the built in methods Ruby uses, which will definitely be a plus. I just hope the examples are more clear in the future chapters and that I get something useful out of it rather than having a list of all of the built in methods.

Here's the point: When you first introduce a piece of code, walk line by line through what it is doing. Gradually back off with later examples and skipping the things the reader has already seen. Continue this, highlighting the new portions in bold, so the reader focuses on the stuff they should be learning in that section. There are only about a million other books that do it this way to use as examples.
