I have to argue against Chris's answer that they are alternatives. I use Shoulda and Rspec together in my Rails application, and they complement each other well.
Rspec and shoulda are alternatives to each other. I started with shoulda, as well, and moving to rspec is as simple as s/context/describe/, s/should/it/, and you're off to the races. Rspec has a bunch of tricks, various integrations, and more complex matchers, so I'm using it more these days myself.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
