There's no Web development material in the book, and no Ruby/Java examples; it's all focused on the Ruby language itself. You can certainly develop standalone Web apps with Ruby, either with some of the basic tools like the CGI library or by rolling your own. There's also the Rack library, which implements a very simple spec for Web apps that make it almost trivial to write one.
Ruby training coming up in September! David A. Black and Erik Kastner team up for fast-paced, four-day Ruby intro, in New Jersey, September 14-17. See http://rubyurl.com/vmzN or contact David.
Being a J2EE programmer (still have to learn many other technologies in it), I am hesitating to dive completely in Ruby.
I dont think Ruby is going to replace Java/.Net, but I sense its going to take away some market share. I am planning to learn Ruby first using it with Java, so that when Java market is down I can go for Ruby. Your suggestions will be really helpful.
"When I ask the question "do you think you're significantly more productive in Ruby rather than Java/C#", each time I've got a strong 'yes'"
"But overall these experiences, from trusted colleagues mean I'm increasingly positive about using Ruby for serious work where speed, responsiveness, and productivity are important."
And keep in mind, that Fowler wrote this in 2006. He did a followup this year reflecting on Thoughtworks use of Ruby (and RoR). Thoughtworks is a Java, .net, and Ruby shop - and they aggregated 3-4 years worth of data on how Ruby and Rails fit into their organization.
Working within web-development means using many languages and frameworks. One of the best things I did was open the book on Ruby (and Rails), which exposed me to many new (and very useful) paradigms. Even if Ruby isn't your preference, you simply cannot afford to not explore new languages ongoing.
As spoken at a No Fluff Just Stuff (NFJS) conference in Denver: "If you aren't learning an alternative language that runs on the JVM (Ruby, Groovy, Scala, Clojure, etc), your already behind."
Articles like one by Martin Fowler and quotes such as "If you aren't learning an alternative language that runs on the JVM (Ruby, Groovy, Scala, Clojure, etc), your already behind." motivate me to learn Ruby as my secondary language in programming to begin with.
Can you please suggest me good beginners book on Ruby, which fills the need of ppl coming from java background, if there is none yet, which book would you suggest me.
Being marketable is a good reason to learn a language, personally, I feel that every Java programmer (especially java programmers) should learn some functional programming paradigm based languages, like Haskell / ML / Scheme / Scala.
Then off course they should also check out the range of dynamic languages like Ruby, Erlang (to name a few). Lot of people ask, oh well what does that buy me? In reality it doesn't get you much; but the truth is that once you start broadening your horizons in languages, you tend to know that there are "different" approaches and ways of solving software puzzles and some of them dare I say are more efficient than others; (It also helps you in the long run, because of your depth, you can make informed software decisions if you are in that position and guide others as well.)
So yes, learning Ruby is good, but my personal suggestion would be to learn a language to appreciate the beauty of a language itself and not JUST because of the marketable skills it provides...
Some thoughts, BTW Ruby is a beautiful language! you definitely should check it out!
