With 1.9.2p0, Date#parse assumes an UE format. Check out format.rb, line: 1042 if you don't believe me. Anyways, how can I make it assume a US format, so that: > Date.parse("10/4/2010") => Mon, 04 Oct 2010 Instead of April 10th. I've tried this: class Date def _parse_eu(str,e) _parse_us(str,e) end end but no luck. Any...

Hello, I'm currently developing a torrent metainfo management library for Ruby. I'm having trouble reading the pieces from the files. I just don't understand how I'm supposed to go about it.

ActiveRecord is a module that contains a number of classes such as Observer and Migration, as well as a class called Base.
