This article title should have "(2004)" added; this is seriously old information. For modern use, something about ARM CPUs would be much more useful since that's what microcontrollers all use now. No one's doing ASM programming on x86 CPUs these days (and certainly not Pentium4 CPUs).

I don't think that's entirely true...it's still pretty common to write high-performance / performance sensitive computation kernels in assembly or intrinsics.
