Is it possible to uninstall ruby gems, rails etc and do a complete clean install?

The easiest solution will be to check out rvm . It lets you have multiple Ruby environments (each with their own set of gems) installed in parallel, which makes it easy to "start fresh" and built the environment from the ground up.

If you really want to uninstall before using RVM (which is indeed the recommended solution), check this blog post by Chad Wooley.

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.
