The best part comes with this comment :
"Many people confuse these two. An application can crash and that''s 
when "kill" comes handy. To say that Linux is unstable just because an 
application has crashed is grossly inaccurate.

Try running Linux without any GUI and see if you ever have to reach for 
that power button!"

Yeah, it's not Linux that crashed, it's only your app that crashed your 
computer...
