Eckel on Java vs Rails: The departure of the hyper-enthusiasts

As always Bruce Eckel is a great read..


The Java hyper-enthusiasts have left the building, leaving a significant contingent of Java programmers behind, blinking in the bright lights without the constant drumbeat of boosterism.

But the majority of programmers, who have been relatively quiet all this time, always knew that Java is a combination of strengths and weaknesses. These folks are not left with any feelings of surprise, but instead they welcome the silence, because it’s easier to think and work….

Clearly Ruby is making important contributions to the programming world. I think we’re seeing the effects sooner in Python than elsewhere, but I suspect it will have an effect on Java as well, eventually, if only in the web-framework aspects. Java-on-rails might actually tempt me into creating a web app using Java again.However, I can’t see Ruby, or anything other than C#, impacting the direction of the Java language, because of the way things have always happened in the Java world. And I think the direction that C# 3.0 may be too forward-thinking for Java to catch up to.

Mainly, I think a pragmatic approach to a language is to assign value based on a) what you can accomplish with it, and b) how easy it is to write in the first place and maintain in the long run. So far Ruby is starting to become interesting on (a) – it was always interesting on (b) -, although we still have to do a lot of stuff in Java if we want to take advantage of a lot of features.

However, in Java there has been a lot of work already done to get you libraries and automated tools. I have been looking for some good IDEs for Ruby and I can’t seem to find anything that is better than just using vim (I’ve looked, but that’s another story) – Eclipse is my yardstick for comparison.

That means that I may want to switch to rails for web app development and maybe scripting, but not for any type of development where I have to apply deep pattern thinking and where I anticipate refactorings to come along as the system grows. It may be easier conceptually to do refactoring in Ruby, but that fact is superceded by the automatedness of doing it in Eclipse. It doesn’t matter if it impacts a lot more files to, say change a member variable name in a domain object, in Java vs. Ruby if I can do it with Alt-R in Eclipse and in Ruby I have to go and change it manually – the masses will not switch until you give them this kind of capability.

On the other hand, I really do like the fact that you can get started in ruby from scratch in a few minutes using things like “gem install rails”, vs. setting up a giant ant/java/spring/hibernate/tomcat on the java side.
