Bad news. The server hosting The Ruby Toolbox went bust on the evening of June 7th. While I do have backups, the original source code is in a very outdated state so I currently don't feel it makes sense to try and get it running again.

For the time being, here is a very stripped down version of the Ruby Toolbox's contents.

Update June 13th: I'd like to invite you to join the discussion on the future of the Toolbox on github. You can also get in touch directly on Twitter.

AssetHat

Load CSS and JS faster. Minifies, bundles, and optimizes CSS/JS assets ahead of time (e.g., on deploy), not at runtime. Loads popular third-party JS (like jQuery, YUI, and Dojo) from localhost in development, and auto-switches to Google's CDN in production. Lets you switch on LABjs mode to load more scripts in parallel. Can rewrite stylesheets to use CDN hosts (not just your web server) and cache-busting hashes for updated images.
