This one is my least favorite one of his, actually. The big problem is that it just didn't actually really work. Tom7 seems to start these projects only a couple weeks before sigbovik deadline (an incredible feat I marvel at regularly) so it is no surprise that some of them end up falling apart (harder drives with the cue carts failed too) but I really wish this one had worked.
The C Compiler that only emits the printable bytes is my favorite one by a mile. The executables can only jump forward and only by an offset between two modestly large numbers. This makes laying out the code in the executable a really interesting problem and relies on weird old behavior where the instruction pointer can wrap on overflow. Wild!
Is pure gold. I don't wanna spoil it, it just keeps getting better and better as the video progresses. I laughed so hard.
If by some freak chance I ever become wealthy, I want to sponsor this sort of research.
