Ask HN: The most useful equations/instructions in the event of an Apocalypse

4 points by betageek ↗ HN
The other side of a business card is always a bit of a waste of space so I want to use it wisely - in the event of an apocalypse, what's the most useful bit of information that would fit* on the back of a business card?

* limit is probably ~500 chars in a compact font, i'll send you a copy of the business card if I use your suggestion ;)

Put some instructions using TeX/LaTeX code as it is probably the only language to survive an Apocalypse

      \documentclass{article}
      \begin{document}
      \def\alist{boil water, keep calm, move to countyside, 
        carry a knife, take food, take clothes, take 3 books}
      \makeatletter
      \@for \i:=\alist \do{
        \texttt{\i $\rightarrow$ }
      }
      \makeatother
      \end{document}
