The problem with object-oriented languages is they've got all this 
     implicit environment that they carry around with them. You wanted a 
     banana but what you got was a gorilla holding the banana and the entire 
     jungle.

• Fundamental idea: Free as in beer

  In a nutshell, the word "free" has a couple of meanings and it's 
  not always possible to tell in context which one the user meant. 
  "Free as in beer" refers to the cost (i.e. money) of the software, 
  while "free as in speech" refers to what you are allowed to do with 
  the software.

• Notion of "intelligent design", as applied to software
  • Isolate components from each other so that they cannot interfere with each other - or even communicate unless there is a reason to do so
  • Stick to the "principle of least authority"; no component should have more privilege than it needs to get the job done
  • The failure of one component should not cause others to fail
  • The health of components should be monitored; if one stops operating properly, the system should know about it
  • One must be prepared to replace components in a running system
