| "There are versions of Windows with no GUI." Do they run in VGA textmode? I have used a program called "window" and today I use tmux but neither of those come from Microsoft. How do I obtain one of these versions of Microsoft Windows that runs in VGA textmode? "The attack surface for any large OS..." Well yes, because they are all large. But what if the OS is small? Let me guess, now you are going to tell me that all OS, e.g., kernel plus userland, are the same size? |
And probably most developers could write an OS/userland by themselves given enough time but it would probably be a long time before it's practically useful or secure.
