Which tools for combining and minifying CSS and Javascript?

Tbh apache's deflate compression + minifying js/css (while leaving them standalone) is enough for small webpages in my taste. Especially when some of them are implemented as external (cdn) libraries.
I sometimes have to make changes in scripts while being away from my workstation, and working on fully minified file(s) would be a real nail in the ass.
