Subject: briefest method of generating a list of random numbers?

Hi all,

I wondered if there was a more compact method of generating things like
a random string, or a random list of numbers than I'm using now (using
ruby 1.9.0-1)

  array = [] ; 100.times {array << rand}
  string = "" ; 100.times {string << (rand(26) + 97).chr}

The temptation is to use

  array = [rand] * 100
  string = (rand(26) + 97).chr * 100

but that only draws one random number a 100 times.

Is there a bit of syntax that I missed?
