I'm one of the HNers that sent in code for the test. The feedback provided by RiderOfGiraffes was useful and the follow up questions were food for thought.
At the time I'd just failed a coding test for a systems programmer role and felt pretty low, which is why I decided to take this on.
In the interview I failed, I fared well in most of the questions, apart from one set involving heavy binary maths — I pretty much forgot basic binary computation from when I did my undergrad course. Following this, it prompted me to buy "Hacker's Delight" by Henry S. Warren. It's a great read if you're into high-performance algorithms http://amzn.com/0201914654
