Computing Internet Books

Writing is art like programming or painting, not every one can be a writer, I cant be a writer, but i know that about myself.
Being technically competent and knowlagable about something does not
nesserarily means you can now go and write a book about it.
The author is a failure when it comes to writing specially technical
books.

a good book writer is for example "Jon Skeet" other writers should take
a look at his style.

I've been a fan of Juval ever since I took an al-day seminar with him at DevConnections a few years ago. He's a great teach and a great writer. However, he is not for beginners.

I have previously read Juval Lowy's Programming .NET Components and it was one of few excellent books which gave deeper explanation about .NET. This book is as great as that one and only one of the few books giving a good explanation about WCF and its internals.

Absolutely the best book I've read on Windows Communication Foundation. A must have book. Juwal explain every single WCF detail in a very well simple form but this don't break the value of this excellent book. A book written for beginners, intermediate and professional WCF developers.

Well done, Juwal.

This book was actually my first exposure to WCF. Many people describe it as a more advanced WCF book than the other more basic ones out there. Although I tend to agree that it is more advanced than other books, I disagree with the implicit suggestion that you shouldn't start with this book if your a beginner. I generally gain better command over a subject by going deep enough to understand what's going on, and what capabilities I have at my disposal.

"Programming WCF Services" does just that. It starts with the simple basics which is important for the novice. But as soon as you understand the basics, you yearn for much more deeper content, which follows in the chapters to come. Although I wish the book would have had a chapter devoted completely to Channels, the overall depth of the book is enough for most use cases that WCF developers will encounter.

Something i really like about Juval Lowy's writing specifically is that he walks you through the thought process of the underlying problem. He shows you the different options that are possible, and then gives his final opinion, thus leaving you satisfied as to why a particular methodology is better than another.

If Juval would consider a 2nd edition, I would recommend a chapter on custom Channel development, and RESTful web services.

All in all, a great book for beginning and intermediate WCF service developers.

Before Larry Lessig began teaching a course on "cyberlaw" in the 1990s, few people knew this awkward term for "regulation of the Internet." But Lessig, now a professor at Stanford Law School, has always kept close to the bleeding edge of technology. He started programming in high school and later helped the U.S. Supreme Court go digital. Even this book's development shows the author's geek //bona fides:// He revised it using a "wiki," a software platform that allows multiple users to edit the text simultaneously via the Web. While the book's details have changed a bit since the first edition, Lessig's main point is the same. Because of its design, the Internet is perhaps the most "regulable" entity imaginable and, unless its users are careful, it will morph into something that diminishes, rather than enhances, liberty. Moreover, trying to keep the Internet "unregulated" is folly. While this book is sometimes bloated and repetitive, we find that it is still required reading for anyone who cares about the social impact of the most important technology since electrification.

This is an important subject ans deserves a lot more attention.

However, it was clearly written by a lawyer for lawyers. I am a software engineer and read many books in my field - but alas was unable to finish this one - important as it is. Its just way to wordy - if it was reduced in size by at least half - and highlighted the salient points clearly and simply - its would be a much better book IMHO.

If your a lawyer you'll like this book - but anyone else - look elsewhere.

Sorry lawerence.

Professor Lessig describes how managing copyright for the digital age will have an impact upon every individual in the future. As we develop and share digitial content how we protect or even abuse copyright will determine if the Internet and other digital technologies will improve information for the global citizen. We stand at the door of one of the greatest era in history, however, how we use and protect digitial information will determine how history will judge our efforts for generations to come. Lessig's book gives us the foundation to build upon and will be up to each individual to determine the final outcome.

You can download this book at no charge in pdf format from Lessig's site.

If you take Web 2.0 at all seriously then, whatever your political or philosophical persuasion, Larry Lessig's Code: Version 2.0 is a compulsory read. My own political and philosophical persuasion is considerably different from Lessig's and consequently I don't entirely agree with either his conclusions or the weight he attaches to some of his concerns, but I still take my hat off to his methodological and philosophical achievement: Code: Version 2.0 presents a novel and undoubtedly striking re-evaluation of some fundamental social, legal and ethical conceptions and makes an entirely persuasive case that our traditional, deeply-held, and politically entrenched ways of looking at the world simply aren't fit for purpose any more.

Intellectually, this is therefore an extraordinary, eye-opening, paradigm shifting, challenging, exhilarating read. (I note some previous comments that this is a book for lawyers: I'm a lawyer, so perhaps that explains my enthusiasm, but this is no ordinary legal text, and should be of interest to anyone with a political, philosophical or scientific bone in their body.)

Lawrence Lessig charts, with a fair bit of technical specificity, the technical and epistemological grounds for thinking that the internet revolution (and specifically the "Web 2.0" revolution) is as significant as any societal shift in human history. Generally, this is not news for people in the IT industry - who deal with its implications day to day - but for our legal brethren, who tend of be of a conservative (f not technophobic) stripe, this ought to be as revelatory (and revolutionary) as Wat Tyler's march on London. Now we have a hyperlinked, editable digital commons, the assumptions with which we have constructed our society need to be rethunk.

For example, copyright: a law framed in the pre-digital era where there was no ready means to replicate "content" which didn't itself involve considerable labour and expense, it made sense to protect intellectual property in this way. But faced with the new commercial imperatives of the digital age, Lessig argues compellingly that the existing legal framework simply cannot apply, that any attempt to fit it to the new social reality which, QED, must have been beyond the contemplation of the framers of the law is a creative (and therefore potentially illegitimate) legal/political act. Down this path, Lessig's arguments have more interest for consitutional lawyers and may lead the lay reader a little cold.

Lessig provides us with an alternative framework for discussing legal issues like copyright, intellectual property protection and privacy, and is convincing that our old tools for conversing on these issues - which predate the digital revolution in its entirely, let alone the internet revolution or Web 2.0 - just won't give us useful answers to our conundrums. Lessig also re-opens the book on what even counts as law - what we mean by "regulability" - in an environment online where the power exists, by computer code, to create "laws" of a more natural kind - that are laws not because they *should* or *may* not be broken, but because they *cannot* be broken.

Lessig's startling conclusion is therefore to reject entirely the utopian wish, frequently expressed by citizens of the net, that traditional legal controls are dead and that Web 2.0 vouchsafes to us an eternal state of libertarian bliss - but to assert that, quite to the contrary, Web 2.0 is, to use his own ghastly expression, "architected" to allow maximum conceivable regulation, and that activities online are capable of a total regulation that, offline, would never have been feasible. Lessig warns therefore that we stand (or at any rate approach) important political crossroads where the public decisions we make as a community about how we allow internet architecture to develop will have a huge bearing on the development of cyberspace - and therefore our rights and personhood in cyberspace - for the hereafter.

Among the fascinating ideas here, which have application way beyond the legal and digital realms, is the "end-to-end principle", by which the internet is (ugh) architected, which says that for a distributed system to be maximally effective there should be the minimum complexity in the basic network necessary to provide common structure to all users so that they can use the information as flexibly as they want: the complexity should therefore be at the edges of the system and in the hands of the user. Thus the core wiring of the internet is a rudimentary router of tiny packets of data which are then assembled by the end user (in a browser or other application). But the same principle applies to physical transport networks (a road system has less intrinsic complexity than a rail system, for example: the complexity on a road network is pushed to the edge and manifests itself in the vehicles we drive: on a rail network by contrast the train is part of the network), and indeed political and social networks (a liberal political regime has less intrinsic complexity than an interventionist one - the complexity is pushed to the edges of the network and users build that amongst themselves). I thought this was a profound insight, and perhaps has implications beyond the scope of Lessig's thesis, and if properly considered have the effect of mitigating some of the alarm he feels.

Just as he rightly brings the utopians to book for believing their hype about this golden new age of freedom - of course governments and vested interests will figure out the net and how to effectively regulate it, like they have every other social revolution since Wat Tyler's time - I think his own vision is needlessly dystopian. It assumes that code will be able, at some point, to regularly, systematically, reliably and effortlessly know every single fact about every one of us - and hence we are ultimately regulable.

But this isn't realistic. Just as it would be impossible to accurately predict the trajectory of a crisp packet blown across St Mark's Square, no matter how sophisticated your equipment and scientific knowledge, the web is too weird, people's applications for it too dynamic and unpredictable and the "true meaning" of our communications too innately susceptible of multiple interpretations for any code to ever fully get the better of us (not even really close). For example, in my organisation I have spent months, with considerable IT infrastructural support, trying to figure how to reliably capture simple, non-controversial attributes of regular documents which routinely and predictably pass between an easily identified and small community of users across a tightly defined and fully monitored part of our internal computer system - and this has proved so far to be quite impossible. The idea that one might reliably capture deliberately masked communications even from this minute sample seems absurd, and the idea that one could do this across the whole world wide web preposterous.

Just as the spammers and virus programmers keep ahead of the filters, our freedom is adaptable and valuable enough to keep ahead of the Man.

Well, that's the hope, anyway. But in the mean time this book is certainly food for thought. It could not be more highly recommended by this reviewer.

I received this product about 3 days after ordering it. I was kept up to date with a tracking number and the product shipped to me in perfect condition.

I bought this book because of the title but I have to be honest the examples are not very clear. I look for a book that has clearly explained examples that lead you to a final product. This book doesn't even tell you which examples to open for each chapter. Most books say open the file (and gives the file name) then it walks you through each step explaining what is being done as you go. This book doesn't do that as evidenced in the chapter about layers where is doesn't clearly explain which files to open or what to do with them to get to the final outcome.

I am learning photoshop for the first time and this book has help me tremendously in my class. It is worth the purchase.

This book was a big dissapointment...there is a ton of important stuff missing...Info on 'actions' ...its not even listed in the index...better off to stick with the CS2 edition.

Conceptually I really like the idea behind these books. You want to find a technique and boom there it is laid out on one or two pages step by step. The problem is it seems I never use them very much. I don't know if the indexing is better in other books or the way it's presented is a little more engaging but I've noticed that after a few years they are always my choice of last resort. Like I said they have a wealth of info packed into them but you should look at how you work and how they're laid out before you buy.

I bought this book back in April to help me learn Windows Server 2008. At first I was somewhat overwhelmed as this is a monster book at nearly 1500 pages. I hung in there and read through Chapters 1, 2 and 3. Those chapters introduce new features, provide advice for planning and give specific instructions for installing Windows Server 2008. They are so well organized and so well presented that I felt better about making the move to Windows Server 2008.

In the acknowledgements, William states he has been working with Windows Server 2008 for six years (since 2002). After reading almost every chapter and page in the book over the past 4 months, it is clear that he knows Windows inside and out --- and probably better than anyone else in IT.

With what I learned from this book, I was able to help plan the migration of our network and directory services to Windows Server 2008. My manager selected me to perform the migration in our test lab. This was such a success I was selected to lead the deployment team, and our deployment is proceeding without a hitch!

The book is so packed with useful information I feel I got my money's worth and then some. I've bought several of Stanek's books in the past and they've never let me down. His writing style is top notch --- clear, concise and no nonsense.

I like this book, but what's with the draft-mode printing? The text is so light compared to my other "Inside Out" books, I wonder if this is Microsoft's way of trying to save some money by printing in what looks like draft mode? I study late at night by a lamp, and I have to strain sometimes to continue reading hours at a time with this light print.

My other issue is the ebook, the font doesn't really resemble the book. It seems like the book is printed in Times New Roman (I could be wrong), but the ebook is printed in...something else that's not too easy on the eyes.

However, the content is excellent, and other than the printing of the book and ebook, I'm glad I made this purchase.

This manual is awesome for all your WinSvr08 needs and it's all delivered in William Stanek's extremely friendly, to-the-point prose. No stand-up routines and asides to wade through to get what you need, but with clarity and intelligence throughout that keeps you reading. Yes, even though it's a computer manual.

Throughout, you'll be rewarded with tons of practical tips and how-tos that make such a difference. For example, I've been using Windows since before WinNT, and I got a bunch of excellent tips in the very first chapters!

WinSvr08's a whole new os, and while the obviously new features are covered, there are major improvements and tweaks to almost everything, and this is a Really Great Guide for pointing out the new way of doing things (even for those things you think you know already.)

If you're going to get one book on WinSvr08, get this one. It's accessible so you can get what you need quickly if you're looking for specific help, while having substantial depth to make a more comprehensive reading of it rewarding. Certainly do recommend it.

Stanek's Windows Server 2008 Inside Out is the definitive resource for network administrators who are deploying and using Windows Server 2008. I've never found a single server book that tells you everything you will ever need to know about any edition of Windows Server, but this one comes close and it digs in much deeper into the most relevant topics than any other Windows Server 2008 book I've used.

I have my MCSE, CCNE, CompTIA Security+ certifications, and I have enjoyed reading Stanek's books for years. He writes everything in friendly easy to understand language, so that you don't get lost in computer jargon. He also has a very organized and very clear style and his details are never off topic. He truly understands Windows and his sense of what's important and what's not makes it possible to read the whole book and get the most information out of it.

I feel that Windows Server 2008 Inside Out is the greatest book for me. I have tried many others and can find more answers in this than any other.

My copy of this book has so many highlights, dog ears, and sticky notes it looks like a porcupine. I'm definitely glad I have it. You will be too.

On a different note, the book is so big it's difficult to lug around. I bought a second copy so I have one at home without having to lug my work copy home.

Stanek once again is able to take technical topics and make them understandable. I have been running WinServer08 since beta one, and this book is an excellent reference for those of us already familiar with the Windows operating systems and newcomers alike.

It's written like all Stanek's others to deliver what I needed. It's so good I read the first few chapters straight through.

I have enjoyed reading Stanek's books for years. My understanding always has increased while reading his books. He understands practical IT in the real world and writes from experience and with a goal to increase our understanding.

I would highly recommend this book to anyone upgrading from previous versions and any current administrators.

The book is good but the source code of Chapter 13 is missing.
It's very frustrating to learn a new technology and see problems with the source code.
Wish the authors can take time to check the source-code is uptodate before releasing a book, or at least put it for download after complaints.
If the authors can update the source code, it will be great.
Otherwise a good book.

I was given this book by one of the Author (John Holiday) during a training on Enterprise Content Management. I have collected quite a few books on SharePoint most proclaiming to be a developers guide but they have chapters after chapters devoted to configuring WWS 3.0 or MOSS. However, this book gives you a very good start and provides step by step guide on creating various solution.
I would recommend this for all beginners and intermediate developers!!!

Working on a few projects I needed to find some good Sharepoint 2007 reference books. This book is excellent with the examples it provides and the way they authors explain it to you. Very easy to understand, clear and concise.

I do however wish they had more real world examples like for example when working with events in sharepoint they would show you how to retrieve the id's from the list lookups when assigning to another list programmatically, or how to change the permission of a selected item for a selected specific group or person, or access active directory.

Other than that, it is a good book that will help you get along your way.

Some of the chapters are totally beneficial while others offer very little and explain things poorly.

I guess if it fits a need it;s worth it, but there was nothing in here you could not Google when needed. i guess it's supposed to take a programmer and show them how to program with SharePoint. if you have time to go page by page and are new to SharePoint you will get more out of it.
I would stick with the Ted Pattison book persoanlly...

I always find WROX books are the best value for money. This book is no exception. The details this book provides is atypical and that is what I find very useful. Devil is in the details and we need that for programming.

If you are interested in Solutions Development on SharePoint Platform, this book is a very good companion.

Overall, I liked this book. When I read this, I was looking at doing some Erlang work; I didn't end up using Erlang, but the book was still enjoyable, and gave me a good overview of the language.

Some things were a bit odd: the organization was not clear, and the order of chapters was confusing. The authors choice of material was seemed unusual to me: he covered a streaming MP3 server, and mentions ID3 tags; he does not, however, describe what they are or describe in detail how his code processes them. Still, the important details of Erlang itself are covered, and perhaps that's the most important part.

Take it easy,

Dave

I made an attempt at working through this book 6 months ago and didn't feel quite comfortable so I dropped it and instead pursued Programming in Haskell. Yesterday I decided to get back into Erlang and found it a complete breeze, powering through the entire book in a few hours.

A lot of things seem to become really easy after working with Haskell, not to say that programming in Haskell is hard, just it twists and bends your mind into a different shape.

Now that I'm abreast of the material covered in this book, I am leaping into a large project with great confidence.

5/5, excellent book!

This book was recommended by a colleague and I was hesitant at first, but it really is an excellent read.

After flipping through the first few chapters, taking in the examples and absorbing what it was spelling out, it really altered the way that I fundamentally look at software modeling. Joe Armstrong's style of teaching by example and breaking things down into the smallest possible space makes this book worthwhile.

Erlang really appears to be an interesting language, and the author's enthusiasm for the subject shows - which is good. It helped me to keep going, when at times the code was a little hard to follow.

The book does a good job of introducing the language. In particular later chapters give emphasis to the topics of concurrency through multiple processes, multi-cores and distributed programs. All very timely subjects for a world that is connected to the Internet, and where even laptops have multi-core processors

I gave the book a 4 star rating because I feel the author somewhat forgot who his audience is.

On page 5 he starts out with a description that fit me almost perfectly, and probably many other readers: "Once upon a time a programmer came across a book describing a funny programming language. It had an unfamiliar syntax [...] it wasn't even object-oriented. The programs were, well, different....Not only were the programs different, but the whole approach to programming was different."

After reading the book I don't feel like the "Erlang Master" that the road map described (pg 9). While the syntax is now familiar, I still look at the Erlang code and it feels foreign. I still have to "decipher" the code instead of read it.

I would have liked the book to more fully address the items from the "Once upon a time" paragraphs. Being that "the whole approach to programming" is different than the OO that many readers are used to, I would have liked to have seen a chapter (or three) on how to best get into that mode of thinking.

I do think the book is a good jumping off point. It gives you more than enough to get started.

However, if you are unfamiliar with languages where functions accept functions which also accept functions as parameters and return another function as a result, you may end up feeling (as I did) that you only have half the puzzle.

I've been working through this book and am very glad for it. I'm not sure how else I'd efficiently have gotten up to speed on Erlang.

The book does need lots of minor work, though - it still feels like a beta piece of software. There are examples / explanations that make use of not-yet (or never) explained functions/modules. The appendix describing some of Erlang's modules only claims that the set of documented modules is incomplete, but doesn't mention that the set of functions within some modules is also incomplete. Etc.

Another issue is the license of the code examples. The author shows some example code for how to do certain things, such as a distributed map function (pmap). After reading the book, it's hard (at least for a newbie) to imagine a different solution than the author's. But if you go to the website containing the example code from the book, you find a pretty restrictive license on the example code. So this leaves the reader in a difficult position: the book only shows you one way to do something like pmap, and the author has a license on that code that makes it unusable to many readers. This is more than a little frustrating.

Finally, the index is very incomplete.

If you're new to Erlang you still want this book. But it would really be a good thing for the author to gather criticism (if he hasn't already) and go a second round.

This is useful in that it explains alot of online jargon, but as a required reading assignment, it didn't peak my interest.

I have bought and sold stuff online for years and this book still had useful information in it. It gives useful, specific sources for many different categories of eCommerce.
I have paid much more for courses and books from so called marketing experts that didn't have near as much information.
So often you will read or hear that you need to do this or that, but they never tell you the specific places that you can go to get it done.
The many different categories of selling advice would at first make you think that it just glosses over them but once you start to read you see that they are one of the strengths of this book... you just keep finding good advice to tweak and improve your online business.
From web site design and boosting traffic to credit card acceptance to keeping your customers happy or even legal advice for people just starting out, it's hard to name just one part that would be considered the best part of this book. Site security to even the basics of chosing a business name are covered.
It doesn't matter if you are only thinking about starting an online business or if you have various web sites and are an experienced eBay user, there will be something in here that will make you glad you bought it.

This book was a real surprise. I fully expected to use it as a resource for new Ebay/Web commerce users that we help teach but found it excelled not only in the basics but in pretty much the whole plan of where you would want to be online in the long run. I am particulary fond of books that discuss legal and accounting set up and this one covers a lot of good info like type of organization, record keeping, copyrights and trademarks, a tax overview etc. A great foundation for the new online business. There is a lot of information regarding web site design, internet security and boosting your sales. Usually many books would leave off in this area but not this one. It has information on taking your retail business online , selling from a storefront and covers some important ideas like affiliate marketing and finding a niche. Whether deciding to operate on Ebay or with your own website this book is jam packed with information. Even as an experienced online user I found myself making notes from many of the sections in the book including those with suggestions on what to do to expand sales, deal with changes and other customer issues. Just as a note this is one huge book. Over 800 pages including the index and for the price a bargain. For Ebayers I would recommend this book and a general Ebay book as a package to buy. If working directly on your own e-commerce site I would recommend this book with with a web 2.0 or social marketing book.

A wonderful reference to have at your desk. It truly is like having lots of books in 1 - 800+ pages!

it's an okay book and it's really big. don't plan on taking it anywhere regularly.

This book is extremely valuable as reference after you have read it through carefully. Everything is in "Plain English", so whether you are a novice or advanced in the field, this will answer your questions. This is "a must" for anyone wanting to learn about Windows Server 2003.

Fantastic. Still reading it, but this is a worthy reference guide and a long but interesting read. The only book I'll own on the subject. No need for anything else, as far as I can tell.

If you're looking for a Windows 2003 book, this is the one. It's comprehensive and well written in a way that caters to newbies and experts alike. As a plus it's printed on high contrast paper in a very readable font.

Need to do something with Windows 2003 server?? GET THIS BOOK....

This is a good reference book. However, if you know nothing about creating web sites it may be of little use. Also, if you wish to start a blog or a blogging business, this book is NOT for you! It only talks about [...], which is so easy to use it hardly deserves a chapter.

Now a days, creating a web site is more about design than development; resources exist on the internet where millions of web developers will share their ideas and creativity for free - but how does one access it and where are these resources located?? The Missing Manual Series, Creating Web Sites addresses these questions and more. This book is an excellent starter book for those who are just getting their feet wet in the world of web design, development and programming, but that's not to say that an expert wouldn't find this book a handy resource. Creating Web Sites also answers a lot of questions that I had about different aspects of web development. The section on e-commerce and the other web resources referenced within the book, points you to the right places in which to grab code, and get ideas to build great web sites. The Missing Manual series is one that I recommend to everyone (this is the 2nd book from the series I own) - all the books are very thorough, but easy to follow; if you're a novice this book should be required, if you're a pro this should be a handy resource to add to your library.

Some of the introductions are a little dated (i.e. jokes that reference beanie babies, etc.), but the other content of the book is still pretty current. This is a really helpful book for the beginning web designer. It is definitely a good reference to have, espically for design students. This book covers things that appear in the software Dreamweaver. It discusses codes for things such as CSS, HTML, etc.

A great book for any novice trying to build a web site. The book is divided into clear sections each giving excellent advise and information. I recommend this to anyone starting a web site. If you are fortunate enough to have Dreamweaver software for web creating I also strongly recommend "Dreamweaver 8 - The Missing Manual.

I have been searching for a good, fairly insightful, starter book on what to do to set up a website, that wasn't too advanced or way to boring.

This is it! The author knows his stuff, brings it into the learning forum in such a way that you are excited to read the next section and re-read for additional insights previously completed sections.

I am going to use this book, and will probably buy more by the same author/publisher.

Not only is there a great framework to this textbook will introduce you to, but this is written in the perfect balance of interesting style and serious technical content along with compelling example that I've ever seen in any book. I give this book my very highest recommendation and I give the rails framework five stars as well for being an excellent easy to use and very functional framework.

This book seems to cover everything that I'm interested in and is able to adapt to different levels of knowledge that I'm able to arrive at in programming in Ruby language. The book does not insult the reader and while it challenges the reader doesn't over challenge or overwhelm any point. I can only recommend it for my particular demographic of rails newbies, but I think this book will work very well for anyone else who might be more familiar with Ruby and the rails framework.

This book is a great intro to Rails, very readable and easy to understand. It also seems fairly comprehensive. The only downside to this book is that it's not Rails 2.0, so a number of the examples are outdated or don't work with the latest versions of Rails (there were significant changes). I was taking a class in Ruby on Rails, and since we were using Rails 2.0, we had to get "The Rails Way" which covers Rails 2.0 but sucks in comparison to this book. "The Rails Way" is a good book for learning Rails if you already know Rails.

I love the framework, the Agile philosophy and I love how the book is structured: straightforward, practical, easy to follow, programmer-oriented.
I truly recommend it for anyone willing to begin in the Rails universe.

It does not reflect the current state of Rails at this time. A new version is supposed to come out in October 2008 that covers 2.0. If you get this version you will need to switch to an older version of Rails, otherwise you'll only get about 68 pages in before the examples stop working.

This is THE book for Rails. Top notch...only WAIT to buy it. As others have said, there is a new edition coming out soon that covers Rails 2.0. Of course...if you can't wait, go to the publisher's web page. They are selling copies of this edition for 50% off, while supplies last. But, some of the code in this book will not work anymore in Rails 2.0. Still, a great book and well worth it even for a quick introduction to the Rails world while you wait for the new edition. Once it's updated, though, for sure, GO FOR IT!
