		<description><![CDATA[Luigi Zingales wrote an excellent article for City Journal, called &#8220;Who Killed Horatio Alger?&#8221; He lays out very clearly how a meritocratic society works, and the diversions that can take us off that track. He says this is what&#8217;s happened with the bubbles and bailouts, and that they risk ending our belief in a meritocracy. He identifies [...]<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=tekkie.wordpress.com&amp;blog=224851&amp;post=2163&amp;subd=tekkie&amp;ref=&amp;feed=1" width="1" height="1" />]]></description>

It&#8217;s a caching technique.

		<description><![CDATA[I was going through exercises in Section 3.3 of SICP recently (Modeling with Mutable Data), and discovered that my version of PLTScheme (4.1.4) does not include set-car! and set-cdr! operators. It turns out the team that maintains this development environment (now called &#8220;Racket&#8221;) changed this in Version 4. Originally Scheme had mutable pairs by default.
