<p>I remember reading an overview of C<small>++</small> development tools for Windows in a past issue of <i>PC Week</i>. In the lower left corner was the familiar box listing the 10 leading concerns of corporate buyers when it comes to C<small>++</small>. Boiled down, the list looked like this, in order of descending importance to buyers:</p>

I&rsquo;m not saying that performance is everything, but optimization isn&rsquo;t even down there at number 10, below online help! Ye gods and little fishes! We are talking here about people who would take a bus from LA to New York instead of a plane because it had a cleaner bathroom; who would choose a painting from a Holiday Inn over a Matisse because it had a fancier frame; who would buy a Yugo instead of&mdash;well, hell, anything&mdash;because it had a nice owner&rsquo;s manual and particularly attractive keys. We are talking about people who are focusing on means, and have forgotten about ends. We are talking about people with no programming souls.</p>

<p>What are we to make of this? At the very least, we can safely guess that very few corporate buyers ever enter optimization contests. Most of my readers do, however; in fact, far more than I thought ever would, but that gladdens me to no end. I issued my first optimization challenge in a &ldquo;Pushing the Envelope&rdquo; column in <i>PC TECHNIQUES</i> back in 1991, and was deluged by respondents who, one might also gather, do not live by <i>PC Week</i>.</p>
