The new post on the Ruby section of O'Reilly authored by Derek Sivers is quite interesting, starting with the title:
Since I am talking about Ruby on Rails here, it is important to mention again Grails and Groovy that provide on the Java platform a simple and productive way to develop applications, and time to get back to the different reasons mentioned by Derek in his post:
#1 - “IS THERE ANYTHING RAILS/RUBY CAN DO THAT
I believe that we will all agree on the fact that you can do anything you want in Java; Web applications, mobile applications, operating systems, rdbms, ... the only limit is your brain! -and your skills ;) -
#2 - OUR ENTIRE COMPANY’S STUFF WAS IN
I think this is one of the key point here. Enterprise is using JavaEE a lot and it is part of the IT, moving to another technology will be expensive even if development is faster. In addition, the developers, administrators are used to develop and manage Java based applications.
And I do not want to talk about how complex it could be when you are building a Rails application on an existing database, designed from a pure Entity/Relation methodology....
#3, #4 #5 - I have nothing special to say here...
#6 - I LOVE SQL
I still see a lot of developers using SQL directly in Java programs. The nice thing about Java is the fact that based on your skills and what you like to do you can choose the way you want to access the database, simple SQL, powerful O-R Mappings, ...
#7 - PROGRAMMING LANGUAGES ARE LIKE GIRLFRIENDS: THE NEW ONE IS BETTER BECAUSE *YOU* ARE BETTER
I love this reason, but nothing special to say, I let you read the original post.
As you can see from the number of comments in Derek's blog -no times to read all of them- this entry generates lot of reactions.
