Static Asset Compilation

Good tips. I've found that http://pngquant.org generates smaller pngs than optipng, but the former is lossy (reduced color palette). I can't tell the difference though.

If you're using .net, RequestReduce [1] is an excellent tool for managing your static assets.

Can someone with knowledge of both this and rails 3.1 explain the difference. Seems very similar.

I found that renaming CSS file names using the hash of the contents does not always work because any changes to dependencies (e.g. images) won't always bubble up to the CSS. I forget all of the reasons why it didn't always work, but it I think it had to do with CDN invalidation for files that I could not-rename (e.g index.html).

The process I use computes the hash of every file and creates a dependency map then I use the hash of the contents of a file and its dependencies to rename the file.

Right. Images and fonts have to be written and hashed first, then used in the template rendering of the CSS file. The CSS references the assets with hashes in the filenames.

Could someone say if using HttpGzipStaticModule really helps? Gzipping small static resources on-the-fly should not take down your cpu by much.

Surely a nice thing to have, but does it help?

You're right, they basically reimplemented Sprockets a.k.a rails assets manager.
