I've written up a detailed analysis of the published parts of the news.arc ranking algorithm: http://www.arcfn.com/2009/06/how-does-newsyc-ranking-work.ht...

I noticed that a few pieces of the algorithm were not released, and the algorithm has surely changed since arc3.1, but the published code explains at least the overall behavior of Hacker News ranking.
