Mostly about effectivity vs. efficiency in terms of game programming.
The mother of all demos
I'm currently watching an impressive demonstration of computer technology from 1968! It's really cool to see someone just demonstrating stuff the way it was back in the later 60's. And more interestingly, he's demonstrating stuff that's practical, something that would sorta catch my attention I'd have to work a lot of thinking and planning stuff everyday without knowing of computers.
Well yeah, it's really interesting to watch. Though not as weird as the famous Erlang advertisement/commercial video.
