I wrote a couple of articles a while ago about minifying css/javascript on the fly. They utilise a mod_perl handler which intercepts outgoing css/js and compresses them on the way out.
Two months ago I hooked up jsmin from a build script for release configurations. It's been helpful to have all of the reader-friendly stuff stripped out automatically without having to store minified copies in source control.

And they've missed the Google Closure Optimizer for JavaScript: http://code.google.com/closure/
I'm not sure why YUI Compressor is last on that list, and why it's not mentioned that it also minifies CSS.
Last could be a position of honor. And he mentions that it produces higher compression ratios.

If anyone uses Kohana I maintain a packaged which wraps the PHP cssmin and jsmin libraries (plus some Kohana juice for serving files/caching)

There is also a port (or rewrite) for Kohana V3 that someone else maintains http://github.com/zazu/minify
For the Django dudes in here:

That's obviously a best practice. Minified code is essentially object code.
For .NET websites, Combres does minifying, compression, and combining of scripts: http://combres.codeplex.com/
For Dojo as mentioned on the post comment
