Lately netbeans remainded me about something that makes great marketing for Ruby on Rails - ability to create application in 10 minutes. By example you can have a look on the netbeans tutorial. Everything looks great, sometimes You can even create the application in 10 minutes … Lets think what You will get in this 10 minutes: * Scaffold of application … without head or legs Thats all, the application generated in 10 minutes does not have authentication, it does not have administrative part. Of course there is a lot of plugins, that helps to add functionality to Yours application. But wait a minute, authors of this plugins cant catch up stable rails. Each few months we have new rails version, and each version is requiring application changes, this is endless. After You finish migration to newest rails, after You find new plugins there is new rails version - and the wheel spins again. Comparing to other applications rails is getting new releases at least twice offten, that would be good if it would have one stable base, but not, the base is changing each few months. And what is the plan, four months after rails 2.3 we will have rails 3.0, it will be more like rails or maybe more like merb? Hopefully it will start slowing down a bit, as it requires now very big efforts to maintain application and keep it up todate. Somebody would say “You can freeze rails, gems and plugins” - yes I can, but I can not freeze my developers, they will learn new rails version, and after one year I will have a team of experienced developers in rails 4.0 or even rails 5.0 and application with frozen reail 2.3 … and try to migrate when the core was rewritten three times during last year. Assuming having steady framewoirk with “broken tables” like Java or less broken DJango makes a lot more work on begining, but development stacks are available, the documentation is more complete, and the major version changes once for few years, this allows developer to understand and modify application code even after ten years.
