<h2 id=divingin>Diving In</h2>
<p class=f>This book, like all books, was a labor of love. Oh sure, I got paid the medium-sized bucks for it, but nobody writes technical books for the money. And since this book is available on the web as well as on paper, I spent a lot of time fiddling with webby stuff when I should have been writing.

<p>The online edition loads as efficiently as possible. Efficiency never happens by accident; I spent many hours making it so. Perhaps too many hours. Yes, almost certainly too many hours. Never underestimate the depths to which a procrastinating writer will sink.
<p>I won&#8217;t bore you with all the details. Wait, yes&nbsp;&mdash;&nbsp;I will bore you with all the details. But here&#8217;s the short version.

<li>HTML is minimized, then served <a href=http://httpd.apache.org/docs/trunk/mod/mod_deflate.html>compressed</a>.
<li>Scripts and stylesheets are minimized by <a href=http://developer.yahoo.com/yui/compressor/>YUI Compressor</a> (and also served compressed).
<li>Scripts are combined to reduce HTTP requests.
<li>Stylesheets are combined and inlined to reduce HTTP requests.
<li>Unused CSS selectors and properties are <a href=http://hg.diveintopython3.org/file/default/util/lesscss.py>removed on a page-by-page basis</a> with a little help from <a href=http://pyquery.org/>pyquery</a>.
<li>HTTP caching and other server-side options are optimized based on advice from <a href=http://developer.yahoo.com/yslow/>YSlow</a> and <a href=http://code.google.com/speed/page-speed/>Page Speed</a>.
<li>Pages use <a href=http://www.alanwood.net/unicode/unicode_samples.html>Unicode characters</a> in place of images wherever possible.
<li>Images are optimized with <a href=http://optipng.sourceforge.net/>OptiPNG</a>.
<li>The entire book was <a href=http://diveintomark.org/archives/2009/03/27/dive-into-history-2009-edition>lovingly hand-authored in HTML 5</a> to avoid markup cruft.
