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 Without going into detail, suffice it to say that my original account signup information was no longer valid and the LinkedIn support staff was unable to even locate my account, let alone reset my password or provide login access.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 »

CSS Hackz Series: Clearing Floats with the Clearfix Hack

I use the CSS clearfix hack on nearly all of my sites. The clearfix hack — also known as the “Easy Clearing Hack” — is used to clear floated divisions (divs) without using structural markup. It is very effective in resolving layout issues and browser inconsistencies without the need to mix structure with presentation. There are countless variations of the clearfix hack around the Web, and for some sad reason, I keep a file updated with all of them. Recent pruning of my clearfix collection yields two excellent float-clearing techniques: First clearfix method: addresses several reported rendering and display bugs […] Read more »

Perishable Press HTAccess Spring Cleaning, Part 2

Before Summer arrives, I need to post the conclusion to my seasonal article, Perishable Press HTAccess Spring Cleaning, Part 1. As explained in the first post, I recently spent some time to consolidate and optimize the Perishable Press site-root and blog-root HTAccess files. Since the makeover, I have enjoyed better performance, fewer errors, and cleaner code. In this article, I share some of the changes made to the blog-root HTAccess file and provide a brief explanation as to their intended purpose. Granted, most of the blog-root directives affected by the renovation involve redirecting broken/missing URLs, but there are some other […] 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 »

Does Google Hate Web Standards?

Consider the Google home page — arguably the most popular, highly visited web page in the entire world. Such a simple page, right? You would think that such a simple design would fully embrace Web Standards. I mean, think about it for a moment.. How would you or I throw down a few lists, a search field, and a logo image? Something like this, maybe: 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 »

Set the Browser Access Point Profile for the AT&T 8525

This unfeatured post provides information for (re)establishing wireless Internet access from AT&T/Cingular Data Service (via WAP or MEdia Net) for the HTC/AT&T 8525 mobile device. Or something. This information is useful if you are unable to connect to the Internet and receiving error messages similar to the following: Error: Your Internet connection is not configured properly. Please verify your settings in Data Connections. Note: Use of the following settings enables the AT&T 8525 to access MEdia Net (WAP) pages using the MEdia Net connection profile. Additional features such as Wi-Fi and device based e-mail along with other 3rd party applications […] 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 »

WordPress Hack: Multiple Email Recipients for Contact Coldform

In the current version of my custom contact-form WordPress plugin, Contact Coldform, there is no built-in method of sending emails to multiple addresses. The thought of adding such functionality had not occurred to me until recently, when a Coldform user asked about enabling it. After a bit of investigation, it turns out that integrating multiple-recipient functionality into Contact Coldform is as easy as it is practical. I will definitely be adding this feature to the next release of the Coldform, however, here is the modification procedure for those who just can’t wait. Read more »
