recently while trying to find workable tasks I tried making a tiny frame buffer library:s :s :s :s which i do sometimes nowadays
And I found something interesting-- mmap with MAP_FIXED lets me map memory to a base address of 0x0 on i686! not what I expected but useful: this means I can hardcover runtime addresses and store them in small-width variables 0.0 i bet people used to do that for demoscene intros
