title: bundler vs RVM vs gems vs RubyGems vs gemsets vs system ruby
body: <p>I am new to Ruby and trying to wrap my head around following concepts: bundler vs RVM vs gems vs RubyGems vs gemsets vs system rub and I'm confused.</p>
  
  <p>Can someone please describe a 'best practice' of how I should manage all this on a fresh install of the latest version of Ubuntu? What should I install, and how should I use it all? </p>
  
  <p>I'm guessing that doing a <code>sudo apt-get install ruby</code> is not be recommended, but I am not sure. I tried it on my system in addition to 'all the other Ruby stuff'. It's just adding to my confusion. I am not talking about Rails but just regular Ruby gems (e.g. Vagrant, Chef, scripts).</p>
