I'm not sure I understand scope - does an out-of-scope variable (I'm using Ruby) exist in memory somewhere or does it stop existing (I know you can't access it). Would it be inaccurate to say that an out-of-scope variable does not exist any more? Maybe this is a philosophical question. ...

I have two rails apps on separate virtual servers, but in the same facility. Both apps can communicate via local ip addresses. This is a two part question: 1) How do I check where the request is originating and limit requests only to those from that location? 2) Do you think this would be secure enough? My gut is telling me this...

So what's the best way of retrieving sections of the string which are delimited by a tab character. At the moment I have: line.split.each do |word| ... end but that is not ...
