Is it possible to completely remove rspec from a project, and then reinstall it again?

I have been developing Rails applications on windows platform for a couple of month now and I'm still looking for right tools how to do it more effectively.

I read that prototype does but didn't know if that means scriptaculous does. I looked at the javascript folder and it had prototype, dragdrop, controls, effects, and application. Is that all scriptaculous? Do I just add a link to it in my layout to use it? Also, The scriptaculous website said all sorts of "big names" use it, but I've...
I'm developing an app (basically an intranet) which has a few small sets of users, each a company using the app internally. Up to now, each set of users has its own deployment with a separate domain name and database, but all living on the same server.

This came up because I realized that, for apps using only HTML response format (no respond_to block), I could send some other type of request (say XML) and get a valid response. Is this considered insecure? Feels to me like ...

My problem is that if the script is a ruby file, the require statements fail inside the script because bundler seems to have done something funky with the load path. Running rails runner Datasource.run_jobs fails: class Datasou...
