The entries and the numbers associated with them were shown in the last post, so choosing a winner is as simple as using 'rand'. For the first prize $100 drawing:

irb(main):001:0> rand(24) + 1
=> 19

1st prize of $100 goes to Duncan Beevers with Using Simile Timeline with Ruby on Rails Views. A well deserved win too, as it's a particularly cool demonstration of how to use a JavaScript / AJAX library to show timelines on your Web pages.

And for the second drawing:

irb(main):002:0> rand(6) + 1
=> 3

2nd prize of $15 goes to Tim Shadel.

Thanks for all of the entries folks, and I hope those of you who didn't win will still enjoy checking out the 24 great articles and resources created for the contest.
