		<description><![CDATA[We&#8217;re currently running Apache2 on an old (and very stable) version of CentOS.  It&#8217;s so ancient it didn&#8217;t come with Apache 2, so we&#8217;ve got it installed from source.

		<description><![CDATA[I had a small problem today when trying to do unit testing of single-table inheritance models in Rails, all my tests initially failed and I wasn&#8217;t quite sure why.  It&#8217;s a pretty simple fix but isn&#8217;t documented too well anywhere, so here&#8217;s the skinny.
My model structure was pretty simple, I had a Content class [...]]]></description>
