		<description><![CDATA[I was bored, so I made this.

Basic introduction to the Mandelbrot set and what this image represents follows.

As you may know from that Jonathan Coulton song, the Mandelbrot set is the set of points c in the complex plane for which the repeated application of z ← z² + c doesn&#8217;t diverge to infinity, where [...]]]></description>

		<description><![CDATA[(This post assumes you read the previous one.)
Today we&#8217;ll be looking at the hill climbing algorithm, which is just a plain old depth-first search with heuristics added.
&#8220;Heuristics&#8221; is a fancy word (from the Greek εὑρίσκω, &#8220;I discover&#8221;) for a very simple concept. In the context of search trees, it simply means that at a every [...]]]></description>

Quite apart from the fact that they incomprehensibly keep pretending their dialect is a language in its own right, they keep applying the wrong words to things, and then passing them on to other languages.
Three examples.
