title: Computer programming
body: <p>i have a question concerning computer programming. Let's say i have only one computer with no OS running. And would like to start to "develop" an OS. basically what i have is a blank sheet an a pen to do so. an a couple of electronic devices. how do i put my instruction into that computer?
  because today we use interpreter of compiler that "turn" programming language into what they call "machine code". But my question could be how to generate machine code from nowhere.
  Thank you for your replies, a link to learn how to do that will be must welcome.</p>
