Tim Bray compares intrinsic qualities of Java, Rails, PHP
InfoQ asked Tim about some of the more surprising conclusions of his intrinsics comparison:
InfoQ: Why is Rails more maintainable than Java?
Mostly because there's less code. The fact that Ruby *forces* MVC on you helps too, also the fact that the templating and ORM and testing and application code are all so tightly integrated helps. Bear in mind that we still don't know how well Rails is going to work outside of the CRUD-centered greenfield app space where it shines.InfoQ: Why is PHP more scalable than Java?
It isn't, but in the Web-app space, it's a little easier to scale (shared-nothing by default); Java requires you to think.InfoQ: So which intrinsic is more important to you?
For me, maintainability; but I'm sure there are lots of other people who would make different choices for very good reasons.Tim also explained the maintainability point further on his blog:
Out there in the wild woolly “Web 2.0” world, maybe getting it built quick is all that matters, because after you’ve knocked ’em dead and been acquired, you can use the money from the Yahoo! buy-out to rebuild everything right the second time. In the enterprise though, I kind of suspect that smart developers and smart managers know that for real apps, the big development cost starts to happen after they’re delivered.You can also see Tim Bray on InfoQ's video interview with him on Rails, Rest, Java, and XML.
