Preventing the Unpredictable White Screen of Death for WordPress Sites with Multiple Themes

For the past several months and up until just recently, Perishable Press had been suffering from unpredictable episodes of the dreaded white screen of death. Although blank white screens happen to virtually all WordPress users now and then, certain configurations seem to trigger crashes more frequently than others. Here, I am referring to WordPress version 2.3. In this case, the unpredictable crashes, inconsistent errors, and general instability began several months ago after I had completed my WordPress theme restoration project. […] Continue reading »

A Way to Preload Images without JavaScript that is SO Much Better

[ Preload Images with CSS ]

Responding to my first attempt at preloading images without JavaScript, CSS-Guru David Bowman graces his audience with a most enlightening set of comments. Apparently, the image-preloading technique explained in the article is “major overkill” and “totally ridiculous.” Of course, I will be the first to admit that I am no expert in CSS, but I do enjoy sharing my discoveries and watching as people improve upon them. My first attempt at preloading images without JavaScript may indeed be “pretty crappy,” […] Continue reading »

3 Ways to Exclude Content from WordPress Feeds

[ Exclude Feed Content ]

This may surprise you, but I post quite a bit of content that never appears in the site’s main feed. It is my impression that a vast majority of subscribers are interested in web/graphic-design and development-related topics, and are really much less interested (if at all) in the miscellaneous odds and ends that wind up in the ever-expanding Perishable Press database. In the past, the process of excluding content from the main feed typically involved changing the post-date to something […] Continue reading »

Quick Reminder About Downlevel-Revealed Conditional Comments..

As more and more people discover the flexibility, specificity, and all-around usefulness of Microsoft’s proprietary downlevel conditional comments, it behooves us to reiterate the importance of utilizing proper syntax. Specifically, for downlevel-revealed, or negative, conditional comments, the commented content will remain visible unless the associated if condition proves false. Continue reading »

How to Cache Mint JavaScript

[ Mint Icon ]

Recently, I spent some time addressing a few of the performance issues pointed out by Yahoo!’s very useful YSlow extension for Firebug. Working on performance tip #3, Add an Expires or a Cache-Control Header, I encountered some difficulty while trying to get the JavaScript used by Mint to cache as desired. Apparently, the HTAccess directives used to cache my other scripts do not effect the two PHP-generated JavaScript files used by Mint. Although I am not entirely certain, I suspect […] Continue reading »

Sharpen Your Site by Removing Unwanted Link Border Outlines

[ Thumbnail: Link Outline Example 01 ]

Lately I have noticed several sites that display those unsightly dotted outlines on high-profile link elements. Typically, these link outlines plague various header elements such as banner images, navigational links, and other key features. This behavior frequently haunts highly graphical site designs and is often associated with various image replacement methods that position the original anchor text offscreen, generally far beyond the left edge of the browser window. When visible, such presentations display a ghastly, four-sided dotted border that wraps […] Continue reading »

WordPress Tip: Quick Hack to Block Spam for the Wordspew Shoutbox Chat Plugin

Recently, I reactivated an older version (1.16) of Jalenack’s Wordspew Shoutbox plugin for the Dead Letter Art Chat Forum. The DLa collective has been working on a new issue of their ‘zine and needed an easy online chat location for impromptu business dealz (ideas, planning, etc.). Almost immediately after reactivating the Shoutbox plugin, the chat forum was flooded with an endless wave of spam. The rate and volume of spam was so high as to render the forum utterly useless. […] Continue reading »

Obsessive CSS Code Formatting: Indentation and Spacing

In the intriguing discussion following the first obsessive CSS formatting article, Jordan Gray brought up the age-old question regarding spacing: tabs or single spaces? I smugly responded that the issue has long-since been resolved, with tabbed spacing as the obvious winner. Let’s take a look at some serious CSS spacing examples.. 1) Strictly Single Spacing Here we have several code blocks showing consistent spacing via single blank space. Three key areas where single spacing is seen in this example: after […] Continue reading »

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.. Just under the wire! Even so, this month’s official Blacklist-Candidate article may be the last monthly installment of the series. Although additional BC articles may appear in the future, it is unlikely that they will continue as a regular monthly feature.

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 »

Pure CSS: Better Image Preloading without JavaScript

[ Preload Images with CSS ]

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 »

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 »
