We started our RubyGems Hackfest Saturday, with a turnout of 6  
people. Five were regulars from Seattle.rb, and we even got someone  
up from Portland! We started Saturday by brainstorming things we'd  
like, writing up story cards, estimating and risking them. Then we  
paired up and got testing!

By the end of day 1, we'd finished cards 1-3 and gotten pretty good  
testing infrastructure in place for stuff we needed. I spent some  
extra time making it so that all unit tests generate their gems on  
the fly, weren't dependent on the location from which they were run,  
and didn't use or create any files in the test directory. We went  
over our estimates by 3.5 hours. Much of that was my fault, it was  
too hot for me to think.

On day 2, we were down to 4 people, but had much better testing  
capabilities. Aaron and Evan finished up the package listing command  
extension and gave .gemrc the ability to have .cvsrc-style command  
option specifications. Eric and I worked on the hardest bug we had,  
which was to get rid of the use of Date. We succeeded on both counts!  
We went over by 1 hour on a task, and under by 1 hour on the other.  
YAY! I've been wanting to conquer this issue for quite some time!

Below you can see a the fruits of our labors:
