I'm just wrapping this site up for Rob right now. Apparently 13run is a game baseball fans play in which each person picks a major league team and tracks the scores they've achieved over a given time period. The first person's team to achieve all scores from 0-13 wins the pot. This site allows anyone to sign up for free, pick the start date for their 13run league, and some additional game parameters, and invite friends to partake. The cool part was writing the scripts to scrape MLB.com and trying to write super optimized sql queries to sort through all of the data. I originally thought I would need to use memcached pretty heavily, but there are only about 4,000 individual scores to sift through and 30 ML teams, so I guess that's no big deal for mysql -- maybe if there were a lot of users
This is also the first full-fledged project I've deployed to Amazon EC2. It definitely runs really fast, and hopefully if the instance blows up I have put all of the proper things in place to recreate it without any problems.
