Ruby on Rails 3.0 is available

I'm not much of a programmer but I can appreciate the value of a good programming language when I see it. While I know Python and dabble with PHP, I've always appreciated Ruby and Ruby on Rails. There is something about the Ruby development scene that perks my interest in this programming language.

Ruby on Rails 3.0 was just released this week. The development of Rails 3.0 has been two years in the making. David August writes:

Why do cool kids build Websites with PHP or Ruby, not Java?

Coach Wei, Java developer, asks the following question on his blog.

Here is a question that I have been pondering on and off for quite a while: Why do "cool kids" choose Ruby or PHP to build websites instead of Java?

At work we're actually moving many of our in-house desktop applications from Python to Java. I wouldn't be too surprised to see us migrate more PHP Web applications over to Java too for some of the reasons Wei gives in his blog post. But I have a theory as to why PHP and Ruby could be considered "cool" and it has less to do with Java's features and more to do with the culture of open source.
