To the right! Autocompletable names

by Edward Z. Yang

In my younger days, the stylistic convention of MM/DD/YYYY confused me; why on earth would people opt for such an illogical system that placed months, days and years in non-hierarchical order? Surely something on order of YYYY-MM-DD would make far more sense: this format is sortable and, all-in-all, quite logical.

Eventually, though, I grudgingly accepted that MM/DD/YYYY, trades machine-friendliness for human-friendliness; after all, the year entry rarely changes, and for humans the month and date are the most important pieces of information. Context is usually more than enough to implicity specify what the year is.

But as a auto-complete user, I've come to appreciate that this sort of ordering can come in handy even when computers are involved. Consider the hierarchically named and non-hierarchally named list of files:

# hierarchally named

# non-hierarchally named

In the hierarchal case, to auto-complete, I need to type t<tab>a<tab>; a total of four keystrokes. In the non-hierarchal case, however, I only need to type a<tab>. If I'm frequently accessing these files, the extra keystrokes add up.

So here's my plea: the next time you're coming up with a naming convention for files you're sticking in a directory, consider both moving the "category" component to the end, and thinking of autocomplete friendly names. Your fingers will thank you for it.
