Hey folks, I've posted an article related to the swift ring format, and how to read it from Ruby. It's a work in progress and, since I'm not a Swift expert by any means, it'll be full of inaccuracies probably. I hope it can be of use to someone else in the meantime. http://rubiojr.rbel.co/hack/2013/02/06/understanding-the-swift-ring-ruby-edition Fixes and corrections greatly appreciated. Cheers.
