Working with Multiple Themes Outside of the WordPress Installation Directory

As you may observe, the WordPress installation that powers Perishable Press is located in a subdirectory named press. This configuration was intentional, as I wanted to have the option to easily install and maintain multiple versions of WordPress in variously named subdirectories. As much as I enjoy this flexibility, many would argue the SEO-related benefits of installing WordPress in your site’s root directory, or at least making it appear that way by using WordPress’ easily customizable “Blog Address” options setting. For example, say you have WordPress installed in a subdirectory called “gibbonz”, but you want your blog’s home page to […] Read more »

Why Can’t I Login to My LinkedIn Account?

This is great. A couple of weeks ago I twittered that I had canceled my LinkedIn account. Without going into detail, suffice it to say that my original account signup information was no longer valid and the LinkedIn support staff was unable to even locate my account, let alone reset my password or provide login access. I know the account was there, but no matter what I tried I could not login. So, without being able to update my information, my only choice was to delete the account and start over 1. The following week, I was finally able to setup […] Read more »

Monitoring Internet Activity for Windows and Mac

Monitoring your computer’s Internet activity is a powerful tool, enabling you to: keep an eye on background processes reveal viruses and other malware expose unauthorized access monitor running programs log process activity ..and much more. The best part? It’s super-easy. Here’s how I do it on Windows XP: Open the command prompt and type “netstat -n 5 > scan.txt” After a minute or two (or any amount of time), press Ctrl+C to stop monitoring Type “scan.txt” to open the log file and check the results Read more »

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. Prior to that, I had removed all of my alternate themes and placed them on a subdomain. Meanwhile, after the […] Read more »

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

Responding to my first attempt at preloading images without JavaScript, CSS-Guru David Bowman graces his audience with a most enlightening triage 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,” but it certainly works. Fortunately, several weeks prior to Mr. Bowman’s dazzling performance, insightful reader Duarte helps the community by […] Read more »

3 Ways to Exclude Content from WordPress Feeds

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 at least a year or so in the past. The thinking was that I could always return to these posts […] Read more »

Quick Reminder About Downlevel-Revealed Conditional Comments..

NOTE: This entire article amounts to nothing more than an in-depth learning experience. After writing the article, I realized (painfully) that either format for the second iteration of the downlevel-revealed comment for XHTML is perfectly fine and displays no ill effects or unwanted characters in any browser. Thus, this article is essentially useless, but I am posting it anyway because I just hate deleting several hours of hard work.. 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 […] Read more »

How to Cache Mint JavaScript

NOTE: This post was written many months ago under the erroneous assumption that caching Mint’s JavaScript was a good idea (for Y-Slow compliance, performance, et al); however, after a brief chat with the man himself, Shaun Inman, I was quickly informed that this was a bad idea: caching Mint JavaScript files will cause Mint to stop functioning. But, for what it’s worth, and for the sake of retaining potentially useful information, I present the original article here for your amusement.. Recently, I spent some time addressing a few of the performance issues pointed out by Yahoo!’s very useful YSlow extension […] Read more »

Sharpen Your Site by Removing Unwanted Link Border Outlines

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 the linked element and then continues to stretch to the left-hand side of the browser window. Here are a few […] Read more »

Blacklist Candidate Number 2008-05-31

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. Oh sure, I see the tears streaming down your face, but think about it: this is actually good news. After implementing the 3G Blacklist, finding decent blacklist candidates is becoming increasingly difficult. […] Read more »

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: Users should be able to toggle the visibility of any division containing post-meta information The post-meta information should remain visible by default and when JavaScript is unavailable The JavaScript should be as unobtrusive as possible, requiring minimal scripting in the markup Here are a couple of screenshots demonstrating this repetitious toggling functionality as employed in the Jupiter! theme (click […] Read more »

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 to announce the next name only to discover a quiet, empty room. And then like Bob gets pissed that nobody […] Read more »

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: deny from proxydomain.com proxydomain2.com Blacklisting proxy servers by blocking individual domains seems like a futile exercise. Although there are a good number of reliable, consistent proxy domains that could be blocked directly, the vast majority of such sites are constantly changing. It would take a team of professionals […] Read more »

Drop-Dead Easy Random Images via PHP

Recently, while restoring my collection of Perishable Press themes, I needed a fast, effective way to randomize a series of images. After playing around with several likely candidates, I finally devised the following drop-dead easy technique: <img src=”http://domain.tld/path/random/image_<?php $random = rand(1,n); echo $random; ?/>.png” alt=”[ Random Image ]” height=”50″ width=”50″ /> This single line of code facilitates the random display of n number of images (image_1.png, image_2.png, image_3.png, etc.) located in the target directory (http://domain.tld/path/random/). For those of you that understand how this works, great! That’s pretty much the entire purpose of this article. However, for those that would appreciate […] Read more »

Pure CSS: Better Image Preloading without JavaScript

After reading my previous article on preloading images without JavaScript 1, 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=”http://perishablepress.com/image-01.png” width=”1″ height=”1″ alt=”Image 01″ /> <img src=”http://perishablepress.com/image-02.png” width=”1″ height=”1″ alt=”Image 02″ /> <img src=”http://perishablepress.com/image-03.png” width=”1″ height=”1″ alt=”Image 03″ /> </div> Thus, as Nanda suggests, […] Read more »

How to Edit the Firefox Custom Dictionary

Oooops! Didn’t really mean to add that particular word to the Firefox custom dictionary. Better remove it now before it causes problems later on.. 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 […] Read more »
