Blacklist Candidate Number 2008-01-02

Welcome to the Perishable Press “Blacklist Candidate” series! In this first post, we begin a new tradition of exposing, humiliating and banishing spammers, crackers and other worthless scumbags.. Every Wednesday, I take a little time to investigate my 404 error logs. In addition to spam, crack attacks, and other deliberate mischief, the 404 logs for Perishable Press contain errors due to missing resources, mistyped URLs, and the occasional bizarre or even suspicious behavior of the search-engine robots.

Perishable Press Site Statistics for 2007

One of the year-end maintenance rituals that I have decided to adopt involves sharing a few annual site statistics for Perishable Press. Over the course of the previous year, Perishable Press has gone through many changes, including switching servers multiple times, eliminating nofollow attributes from comments, and even a complete site overhaul and restructuring. Despite the chaos surrounding such events, traffic levels have continued to increase, bounce rates have steadily decreased, and the number of feed subscribers continues to grow.

Do You Have a Year-End Maintenance Ritual?

Over the past several years working online, my year-end maintenance routine has evolved from simple website backups to a robust strategy involving many important and useful tasks. Some of the items on the list have indeed been performed multiple times throughout the year, but are included here to emphasize their importance. Additionally, many of these tasks are great for helping bloggers gain a clearer picture of their overall online empire, while attaining a sense of annual “closure” concerning the work […] Continue reading »

Are Adblock-Plus Visitors Seeing Your Content?

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 Enable PHP Error Logging via htaccess

In this brief tutorial, I will show Apache users how to suppress PHP errors from visitors and enable PHP error logging via htaccess. Tracking your site’s PHP errors is an excellent way to manage and troubleshoot unexpected issues related to plugins and themes. Even better, monitoring PHP errors behind the scenes via private log is far better than trying to catch them as they appear at random visits. Thanks to the magical powers of htaccess, there is an easy way […] Continue reading »

Yahoo! Slurp in My Blackhole (Yet Again)

Yup, ‘ol Slurp is at it again, flagrantly disobeying specific robots.txt rules forbidding access to my bad-bot trap, lovingly dubbed the “blackhole.” As many readers know, this is not the first time Yahoo has been caught behaving badly. This time, Yahoo was caught trespassing five different times via three different IPs over the course of four different days. Here is the data recorded in my site’s blackhole log (I know, that sounds terrible): Continue reading »

Focus on the Details: Optimizing Images for Humans and Machines

In this article, I discuss how to get the most out of your site’s images by optimizing them for both people and search engines.. For many sites, images play an important role in the communication process. If used correctly, images have the power to make your articles come alive with clarity and vibrancy. Some visitors may merely notice the image and continue reading, while others will want to know more about your images and dig deeper. While checking out your […] Continue reading »

More Server Mayhem

Just when I thought I had finally solved my web-hosting woes by transferring to a virtual private server, I am slapped in the face by the cold realities of server memory limitations. Apparently, WordPress-powered sites are extremely resource-intensive, requiring insane amounts of random access memory (RAM), something which does not concern those of us working from shared hosting accounts. On a shared server, system resources are shared among the various accounts that reside on a particular server. When one of […] Continue reading »

Quick JavaScript Tip: Auto-Highlight Form Inputs and Textareas

I realize that probably everybody already knows this elementary and absolutely dead-simple JavaScript tip, but I was surfing around the other day and encountered a page that made great use of some auto-highlighted textarea content. The idea is simple, include a snippet of JavaScript to enable users to automatically highlight/select upon focus any chunk of text located within a form input or textarea element. Continue reading »

What’s Up Dude

Hello! If you are seeing this page via the default WordPress theme (i.e., blue header, based on Kubrick), welcome to the new server! I recently upgraded my hosting to a virtual private server, and finally reassigned the domain name servers to resolve to the new address. So, if you are here and everything seems to be working, then everything went according to plan and I will be able to complete the transfer on Saturday (Lord willing). If, on the other […] Continue reading »

Site News: Bad Behavior Spasm, Switching to New VPS Server..

Hello! As many of you already know, the popular WordPress anti-spam plugin, Bad Behavior, caused some problems yesterday, and as a result many bloggers and users were locked out of their favorite sites, including this one. As for now, the problem seems to be fixed, however, the experience of being locked out of my own site has left a rather unpleasant taste in my mouth. Needless to say, I will be reconsidering the continued use of Bad Behavior as a […] Continue reading »
