		<description><![CDATA[Last week, my former employer theOTHERmedia open-sourced the last project I worked on there: Helium. It&#8217;s a web application that lets you deploy JavaScript packages from Git and load them on-demand into any website by including a single script tag. There&#8217;s been a lot of innovation in JavaScript deployment recently, and Helium fits a particular [...]]]></description>

		<description><![CDATA[Dean Edwards recently released version 3.1 of Packer, his JavaScript compression tool. You&#8217;ll be pleased to know I&#8217;ve been keeping up with development, and I&#8217;ve just released PackR 3.1. PackR is a Ruby version of Packer that can be used from the command line or within Ruby apps. sudo gem install packr This release improves [...]]]></description>

		<description><![CDATA[I put out a few new software releases over the last few days, and thought I&#8217;d gather them into one post rather than lots of little ones. Let&#8217;s start with the biggest. Update: for those wishing to contribute bug reports (as failing test cases) and patches, Bluff is hosted on Github. In what can only [...]]]></description>

		<description><![CDATA[Another quick update: PackR received an update today that means that when you use its :shrink_vars mode, it won&#8217;t minify any variables called $super. In Prototype, $super is used to implement inheritance and your class definitions will break if you change its name. I didn&#8217;t really want to make PackR inconsistent with Dean&#8217;s original, but [...]]]></description>

I&#8217;ve not got myself all set up on RubyForge yet, but in the meantime you can download the gem from my subversion [...]]]></description>

		<description><![CDATA[Quick note: at the suggestion of Aman Gupta, PackR now supports Packr.pack, Packr.minify and Packr.pack_file as class methods, so you don&#8217;t need to create an instance of PackR before doing anything. Originally, I wanted PackR&#8217;s design to mirror the JavaScript version to make maintainance easier, but these methods are a tiny addition so I&#8217;m happy [...]]]></description>

		<description><![CDATA[Update: turns out this is a lot easier than the method presented below: see Christoffer Sawicki&#8217;s implementation. Consider my method an example of what happens when you&#8217;re trying to port features from one language to another and end up looking in all the wrong places for a solution. I know what you&#8217;re thinking: we already [...]]]></description>

		<description><![CDATA[I&#8217;ve no idea who may have done this already, but I certainly coundn&#8217;t find anyone who had in five minutes of searching. I&#8217;ve written a Ruby port of Dean Edwards&#8217; Packer, and released it as a Rails plugin. It includes a rake task for batch-processing the scripts in your application. Install like so: ruby script/plugin [...]]]></description>
