title: Where are the best explanations of variables, pointers, references and memory addresses on the net?
body: <p>Although I think that I've got that now (the light bulb is pretty bright now but still flickering a little bit), I'd like to read more stuff about pointers, variables, references, memory addresses, etc. Just the whole thing, i.e. what I have to understand when hearing thre term "reference" (think it's just a pointer, not sure).</p>
  
  <p>So let us know your sources! Great articles, books, PDF's, videos, whatever. Anything is appreciated.</p>
  
  <p>Thanks!</p>
