Rails slideshows

There are some great Rails slideshows on SlideShare, here are some of my favourites:

Scaling Twitter:

“It’s Easy, Really.

1. Realize Your Site is Slow
   
2. Optimize the Database
   
3. Cache the Hell out of Everything
   
4. Scale Messaging
   
5. Deal With Abuse”

Introduction to Active Record:

“I have never seen an Active Record implementation as complete or as useful as rails.”
Martin Fowler

Ruby on Rails Resources (RESTful development):

“Constraints are liberating (a straight jacket for your mind)”
