Ask HN: How do you find a startup partner?

I'd like to make a startup within the next few years. Having someone else to work with in getting the company going would be incredibly helpful, especially since I don't have any cash to actually pay an employee. It's rare to find wildly optimistic people with the risk tolerance to start a company, the drive to make something new, and the technical skills needed to actually execute. How do you find people like that?
