The same thing works in Ruby.  You don't need the dollar signs unless you
want to specify global scope, though, and you don't need semicolons
unless you want to put the lines of code on the same text line.  The term
for what you're doing here is "ternary operator".

By the way, in your code, you should really use longer variable names
that describe their purpose.  It not only helps you understand your own
code later, but also helps others understand what you're doing when you
ask for help.
