I never really understood Ruby on Rails. I had it on my list of things to do for a very long time - learn c++, ruby on rails, take bin out, but based on some Ruby on Rails developers it is a more worthy time investment than the two other options. The best thing I can see about it in conjunction with Amazon’s Web Services is the saleability. It’s like having a whole load of power there - when you need it and not when you don’t!
It claims on the website I was looking that “ruby does a lot more with a lot less code” and that its quick to dispense and integrates easily across the board. Bold Claims but I can see that if you build a Ruby on Rails Portfolio it should work out for you, its one of those illusive less common code bases that will brighten up any cv and almost assure you a role at a Ruby on Rails Company due to the lack of professionals covering it. Unfortunately for me I will probably never get round to mastering it - because as of yet I have never found something I can’t deal with in php etc. But should I ever find the need I would probably hire rather than learn, ROR definately worth a look though if your a new developer with a bit of spare time - then when you get pro - give me a call!!
