Invite Only: Traffic Control via Whitelist

Web developers trying to control comment-spam, bandwidth-theft, and content-scraping must choose between two fundamentally different approaches: selectively deny target offenders (the “blacklist” method) or selectively allow desirable agents (the “opt-in”, or “whitelist” method). Currently popular according to various online forums and discussion boards is the blacklist method. The blacklist method requires the webmaster to create and maintain a working list of undesirable agents, usually blocking their access via htaccess or php. The downside of blacklisting is that it requires considerable […] Continue reading »

Feed Tester

Note to WordPress 2.0.5 users: Everything was working fine on this site before upgrading to WP 2.0.5. After upgrading, apparently, our feeds stopped validating and the BDP RSS Aggregator plugin refused to update our own feeds. After several hours investigating the situation, we determined that the Live Comment Preview plugin was interfering with our feeds validating, while the upgraded WordPress (2.0.5) was responsible for problems with the BDP plugin.

Add RSS Feed Link Icons to WordPress Category Listings

Category Links via wp_list_categories()

This brief tutorial explains two methods for adding RSS feed link icons to category listings. Let’s say that you have a list of category links, where each link targets a specific category view. Now let’s say that, next to each category link, you would like to provide a icon that links to that particular category’s syndicated feed.

Extreme Makeover for Gravatars in WordPress

Gravatars have become a popular way of adding spice to the “comments” page of many WordPress-powered sites. So popular, in fact, that the gravatar server is often overloaded, bogged down with millions of gravatar requests every second. This immense server load effects user pages everywhere, resulting in slow loading times, unresolved server requests, and missing gravatars.

Category LiveBookmarks Icon

CLB+ Thanks to some valuable feedback, several inconsistencies were discovered in our Category LiveBookmarks plugin for WordPress.
