Diane's silk dress costs $89

What could a woman's wardrobe have to do with computer systems?

This is a clever mnemonic devised by Geoff Kuenning of Harvey Mudd College to help him remember which registers are used for passing arguments in a Linux x86-64 system:

%rdi:   Diane's
%rsi:   Silk
%rdx:   dress
%rcx:   costs
%r8:    $8
%r9:    9

Thanks to Geoff for providing this helpful aid!
