PHP Short Open Tag: Convenient Shortcut or Short Changing Security?

Most of us learned how to use “echo()” in one of our very first PHP tutorials. That was certainly the case for me. As a consequence, I never really had a need to visit PHP’s documentation page for echo(). On a recent visit to Perishable Press, I saw a Tumblr post from Jeff about the use of PHP’s shortcut syntax for echo() but somewhere deep in my memory, there lurked a warning about its use. I decided to investigate. Continue reading »

Miscellaneous Code Snippets for WordPress, Windows, and Firefox

One of the original purposes of Perishable Press involved serving as a “virtual dumpster” for all of my miscellaneous code snippets. Over time, I continued elaborating to greater degrees on the various code recipes that I was posting, until eventually those brief snippet posts evolved into complete, richly detailed articles (at least from my point of view). Now that I enjoy the luxury of writing for an incredible audience, I try to avoid posting anything that doesn’t include an accompanying […] Continue reading »

Recently, Joost de Valk shared an excellent technique for adding spam and delete buttons to comments on your WordPress-powered blog. The idea is to save administration time by providing links to either “spam” or “delete” individual comments without having to navigate through the WordPress Admin Area.

This article shares […] Continue reading »

85 Firefox Shortcuts for Mac and PC

As my browser of choice, Firefox provides all the functionality I need for web design, application development, everyday surfing, and much more. With a handful of choice extensions installed, Firefox is a lean, mean “get-it-done” machine. Plus, I am always looking for new ways to boost productivity and increase efficiency. Of course, an excellent way to do this involves learning and using as many mouse and keyboard shortcuts as possible. Over the past few years, I have collected oodles of […] Continue reading »

WordPress Error Fix(?): Increase PHP Memory for cache.php

This trick isn’t guaranteed to prevent all WordPress-generated PHP memory errors, but it certainly seems to help reduce their overall occurrence. For some reason, after my host upgraded their servers to Apache 1.3.41, I began logging an extremely high number of fatal PHP “memory exhausted” errors resulting from the WordPress cache.php script. Here is an example of the countless errors that are generated: Continue reading »

Optimizing Google Analytics Performance

It has occurred to me lately that I no longer use Google Analytics for Perishable Press. Instead, I find myself keeping an eye on things using Mint almost exclusively. So, the question now is: do I continue serving the GA JavaScript to keep the profile active just in case I ever need the additional stats? I mean, Mint already does a great job at recording all of information I could ever need, so I no longer see the use for […] Continue reading »

Are Adblock-Plus Visitors Seeing Your Content?

[ Screenshot: Adblock Plus Ruleset Filter Option Panel ]

As Firefox continues to grow in popularity, it is inevitable that more and more users will install plugins such as Adblock and Adblock Plus. As we know, such extensions work by filtering site contents through a list of predefined wildcard directives and other rules. Users may also customize the block-list by right-clicking on unwanted images or even subscribing to an automated filterset updater. Apparently, a significant number of Firefox users employ these extensions to help control the relentless flood of […] Continue reading »

Optimize WordPress: Pure Code Alternatives for 7 Unnecessary Plugins

In this article, my goal is to help you optimize WordPress by replacing a few common plugins with their correspondingly effective code equivalents. As we all know, WordPress can be a very resource-hungry piece of software, especially when running a million extraneous plugins. Often, many common plugins are designed to perform relatively simple tasks, such as redirect a feed, display a random image, query the database, etc. For those of us comfortable with editing PHP and htaccess code, there is […] Continue reading »

How to Fix the Wonky Windows XP Clock

I don’t know about you, but ever since the 2007 change in daylight savings time, my installation of Windows XP has had a difficult time (so to speak) maintaining consistently accurate time. Ever since the change, Windows XP has been randomly resetting its clock (as indicated via the Taskbar) to display time incorrectly. Specifically, WinXP will automatically (i.e., without user intervention) set the time to be one hour earlier than the actual time. For example, if the time is actually […] Continue reading »

Fixing Mint after Switching Servers

After switching Perishable Press to its current home at A Small Orange, I began noticing an unusual problem with referrer data displayed in Mint. Specifically, the first item recorded in the XXX Strong Mint data panel — for both “Most Recent” and “Repeat” views — displayed several thousand hits for various site resources, all reporting the following IP address: Continue reading »
