• Server
• Work fine in dev mode, but the problem is that it makes too many (100+) calls to the database for one person's matter, too much load in the server.
• gem bullet - more efficient querying
• gem brakeman - security tool for RoR
• users cannot change their role, 但是user可以通过某种方式把自己的role换成admin
• operational requirements:
  • eg. must use certain versions of ruby / rails
• acceptance test -- cucumber test
