1 Paris: But what happens to us if we can't get this upgrade installed?
2 [sign]: {over an ominous looking doorway leading into a...} Maze of twisty passages, all alike.
3 Spanners: We may be about to find out...

For those to whom the phrase on the sign above the door means nothing, it is a reference to the first ever computer text adventure game: Adventure. Ah yes, those were the days, when we played computer games written in FORTRAN.

Hey, we go all out on the special effects budget here.

I know a guy who still programs in FORTRAN, by the way. Actually, I probably know several. FORTRAN 77, I mean*. "Conservative" is not the word to describe astronomers' approach to programming their data analysis code. More like "mummified".

* Apparently there have been Fortran 90, 95, 2003, and 2008 since! They even changed the ALL-CAPS spelling!
