What is the Difference Between XHTML 1.0 Strict and XHTML 1.1?

As some of you (e.g., Louis) may have noticed during the recent site redesign, I decided to switch the default doctype from XHTML 1.0 Strict to XHTML 1.1. Just in case you were wondering, XHTML 1.1 is different than XHTML 1.0 in three important ways 1: On every element, the lang attribute has been removed in favor of the xml:lang attribute On the a and map elements, the name attribute has been removed in favor of the id attribute The “ruby” collection of elements has been added Beyond these three differences, XHTML 1.1 is identical to XHTML 1.0. Personally, I chose […] Read more »

Serve Yourself: Why Feedburner Needs a Feed Fix

If you are using Feedburner to deliver your feeds, chances are high that most — if not all — of your loyal readers have subscribed to the Feedburner-specific version of your feed’s URL. This is not a good idea for a couple of important reasons: Complete content-delivery failure if/when the Feedburner service goes down Cohesive branding strategy impossible because visitors see Feedburner’s name in feed URL instead of your own At this point, millions of feed subscribers have Feedburner-branded feed URLs listed in their feed readers. If/when the venerable Feedburner service should ever fail, the results would be disastrous. Feedburner […] Read more »

Important Note for Your Custom Error Pages

Just a note to web designers and code-savvy bloggers: make sure your custom error pages are big enough for the ever-amazing < cough> Internet Explorer browser. If your custom error pages are too small, IE will take the liberty of serving its own proprietary web page, replete with corporate linkage and poor grammar. How big, baby? Well, that’s a good question. In order for users of Internet Explorer to enjoy your carefully crafted custom error pages, they need to exceed 512 bytes in size. Using proper doctype markup, your custom pages should include more than around 10 lines (roughly) of […] Read more »

First 30 Days without Bad Behavior

Approximately 30 days ago, I completely uninstalled the Bad Behavior plugin from Perishable Press. As you may recall, many Bad Behavior users were unexpectedly locked out of their own sites and forced to either uninstall or upgrade in order to fix the problem. Of course, in my perpetual battle to optimize and streamline everything, I decided to drop Bad Behavior from the otherwise obligatory WordPress anti-spam trinity. 30 days later.. I am happy to report that Perishable Press has not seen a noticeable increase in comment spam since the removal of the Bad Behavior plugin. Of course, during the past […] Read more »

Comprehensive URL Canonicalization via htaccess for WordPress-Powered Sites

Permalink URL canonicalization is automated via PHP in WordPress 2.3+, however, for those of us running sites on pre-2.3 versions or preferring to deal with rewrites directly via Apache, comprehensive WordPress URL canonicalization via htaccess may seem impossible. While there are several common methods that are partially effective, there has not yet been available a complete, user-friendly solution designed specifically for WordPress. Until now.. In this article, I share my “secret” htaccess URL canonicalization formula. I originally developed this method in July of 2007, and have been using it successfully on a variety of WordPress-powered sites since that time. Thus, […] Read more »

A Moment of Clarity

Finally, after seven years of working online.. a moment of clarity. It all seems so clear now: your blog is an extension of yourself, a digital representation of your very being. Online, your site is you, revealing your interests, personality, intelligence, wisdom, and anything else that may be deduced from various levels of inquiry. Whether you realize it or not, your website is more than a well-presented database, it is your virtual self, your virtual existence in the infinite realms of cyberspace. Read more »
