Confessions of a PackRat
Location: Pavilion 1 Audience level:
When the Facebook game PackRat was released in early 2008, it quickly
took off, and now serves over 12 million page views a day. This
session will highlite some of the lessons learned while building and
scaling the game — including hard numbers, and code. Specifically:
- Using the cloud: the pros and cons of running a popular app on EC2,
S3, SQS, and SimpleDB.
- MySQL pitfalls: how scaling the database tier nearly killed us, and
how we survived.
- Caching strategies: memcached vs. memoization, and the best of both worlds.
- Interacting with Facebook: third-party libraries vs. rolling your own.
- Dealing with cheaters: detecting and thwarting duplicate accounts,
bots, and GreaseMonkey hacks.
- Why we re-wrote the application from scratch, against conventional wisdom.
