I've spent the last two days implementing VGA and basic graphics support in my OS, and it's great to watch this and see something I know I can implement in a short period of time with what I've already built. Good for morale if nothing else.
<i>Unix compilers are slow, so to entertain myself while I am waiting, I can play Asteroids!</i><p>Good lord. The whole video had an underlying tone of <i>fun</i>.<p>I have read this repeatedly and heard it in person from several older engineers: "unix is a toy", "unix is for playing video games and writing term papers", "unix is for usenet", etc.<p>During that time, if I was a buttoned down government or corporate programmer with IBM and Honeywell training, jockeying Cobol, assembly and Fortran, I too would eschew this newfangled game-playing computer.<p>[Edit: I was gonna say Dan Ingalls invented bitblit operation that made 2d graphics possible, then I saw he had a hand in the production of the video as well ;-) ]
<i>When I want to compile a program, I don't have to exit the program, I just go to another layer and type make</i><p>Although my current setup for editing and compiling is still eerily identical to that.
