Universal www-Canonicalization via htaccess

During my previous rendezvous involving comprehensive canonicalization for WordPress, I offer my personally customized technique for ensuring consistently precise and accurate URL delivery. That particular method targets WordPress exclusively (although the logic could be manipulated for general use), and requires a bit of editing to adapt the code to each particular configuration. In this follow-up tutorial, I present a basic www-canonicalization technique that accomplishes the following: Continue reading »

Toggle Element Visibility via JavaScript

Recently, while restoring the popular Jupiter! WordPress theme, which several readers use to “skin” the Perishable Press website, I found myself searching for a simple, effective JavaScript technique for toggling element visibility. Specifically, I needed to accomplish the following design goals: Continue reading »

Blacklist Candidate Number 2008-04-27

Welcome to the Perishable Press “Blacklist Candidate” series. In this post, we continue our new tradition of exposing, humiliating and banishing spammers, crackers and other worthless scumbags.. Since the implementation of my 2G Blacklist, I have enjoyed a significant decrease in the overall number and variety of site attacks. In fact, I had to time-travel back to March 1st just to find a candidate worthy of this month’s blacklist spotlight. I felt like Rod Roddy looking over the Price-is-Right audience […] Continue reading »

Obsessive CSS Code Formatting: Opening and Closing Brackets

Following my recent post on CSS code formatting, I was delightfully surprised to have received such insightful, enthusiastic feedback. Apparently, I am not the only person passionate about the subtle nuances involved with the formatting of CSS code.

How to Block Proxy Servers via htaccess

Not too long ago, a reader going by the name of bjarbj78 asked about how to block proxy servers from accessing her website. Apparently, bjarbj78 had taken the time to compile a proxy blacklist of over 9,000 domains, only to discover afterwards that the formulated htaccess blacklisting strategy didn’t work as expected. Here is the ineffective htaccess directive that was used: Deny from proxydomain.com proxydomain2.com Blacklisting proxy servers by blocking individual domains seems like a futile exercise. Although there are […] Continue reading »

The Pros and Cons of Blogging

Among my friends, family, coworkers, and other social acquaintances, there are not many “bloggers.” In fact, there aren’t any. Two or three of my old friends have websites that are updated once or twice per year, but none are actively blogging and sharing their ideas with the online community. Many of my “non-blogging” peeps simply don’t “get it.” To them, the whole idea of consistently updating a website with new material seems like a big waste of time. In fact, […] Continue reading »

Pure CSS: Better Image Preloading without JavaScript

After reading my previous article on preloading images without JavaScript1, Nanda pointed out that adding extra markup to preload images is not the best approach, especially where Web Standards are concerned. Mobile devices, for example, may experience problems when dealing with the following preloading technique: /* ADD THIS TO CSS */ div#preloaded-images { position: absolute; overflow: hidden; left: -9999px; top: -9999px; height: 1px; width: 1px; } <!– ADD THIS TO XHTML –> <div id=”preloaded-images”> <img src=”https://perishablepress.com/image-01.png” width=”1″ height=”1″ alt=”Image 01″ […] Continue reading »

How to Edit the Firefox Custom Dictionary

As one who takes full advantage of the custom dictionary in Firefox, I occasionally find myself adding nonexistent or misspelled words to the dictionary by accident. Not wanting to deal with a false negative down the road, I always take the time to stop what I’m doing, locate the custom dictionary, and remove the erroneous term. Finally getting sick of trying to remember the esoteric location in which Firefox stores the personal dictionary, I decided to make a few notes […] Continue reading »

Three Unsolved WordPress Mysteries

After several years of using WordPress, I have at least three unanswered questions: What’s up with the WordPress PHP Memory Error? Why do certain phrases trigger 403 “Forbidden” errors when saving or publishing posts? What happened to the Plugin Pages in the WordPress Codex? Let’s have a look at each one of these baffling mysteries.. Continue reading »

Obsessive CSS Code Formatting: Patterns and Trends

Call me strange, but I format each of my CSS rules according to the following structure/pattern: div#example element { margin: 5px 15px 5px 0; border: 1px solid #444; line-height: 1.5em; text-align: center; background: #222; font-size: 10px; display: block; padding: 5px; color: #888; float: left; } div#another div.example element { border: 1px solid #444; margin: 7px 0 17px 0; letter-spacing: 1px; font-weight: bold; background: #222; font-size: 1.1em; cursor: pointer; display: block; padding: 3px; width: 308px; color: #888; clear: left; float: left; […] Continue reading »

WordPress Themes: Alphabet Series

Since the launch of Perishable Press way back in 2005, I’ve been working on a series of “alphabet themes”, where each new WordPress theme design is named with a different letter of the alphabet. This began in 2005 with the first alphabet theme, “A” for Apathy. Several months later, the next theme design was “B” for Bananaz. Then “C” for Casket, and so on and so forth. An entire set of 26 WordPress themes, one for each letter of the […] Continue reading »
