  • close your files, flush your files, fsync() your files, sync() if you have to, just don’t be stupid.
  • don’t use globals for mutable state. especially when you’re in a multi-threaded environment. or you’re interested in correct answers.
  • there’s a good chance the ORM is writing shitty sql.
  • coffee != sleep
  • more tests!
