[WellRailed] Re: Improving the precompile experience

When the time comes when things are on fire and you have to deploy an
urgent patch -- having a deploy that only takes a couple of seconds
can be pretty valuable.

My position is that assets should only be precompiled if there are
changes affecting assets since the last deploy. Here's a Capistrano
deploy.rb snippet that checks this: https://gist.github.com/2202542

Personally, I'm indifferent on whether this should be done client-side
or server side. Arguably, you save CPU cycles precompiling from a
single location if you have multiple frontend servers... but other
than that it should take the same elapsed time (probably less, if you
have a decent server) whether you do it before or during a deploy.
That is, you still have to wait till your assets precompile before you
can deploy whether or not you do it server(s) or locally.
