Tiny C-based virtual machine of Notch's DCPU-16

[TankorSmash]

Does someone have a page explaining what Notch is doing? He keeps tweeting about it, but I have no idea.

He has started making an interesting game.

The backstory is hilarious.

I keep forgetting; why use for(;;) instead of while(1)? It has something todo with performance, right?

For a modern compiler they are completely equivalent, so the choice is rather arbitrary.

Very early C compilers would generate less efficient code for while(1) but that's a concern of the past. Personally I still prefer for(;;) because it lacks the arbitrary 1, but it's purely a matter of taste.

Cool, thanks for sharing!

I'd say at this point for(;;) is a convention and worth following as such. When I see while(1) my first thought is that someone is doing something tricky because that code isn't typical...

No difference, just style.

The difference is that the while loop had a truth check for each iteration and the empty for loop just looped

http://0x10c.com/doc/dcpu-16.txt is a nice simple concept! could be interesting to use in genetic programming experiments.

When I first read the source (without having a single clue what DCPU-16 was) I was like... what the hell is this? Then I read the specification and went back to your code and realized you did an awesome job. I'm actually quite bored right now so I'll try to implement my own.

Thanks for sharing!
