Feed your Image via Atom or RSS

This quick tutorial explains how to add images to both Atom and RSS feeds. Although both formats allow for image-inclusion, feed-reader support for image-display is currently quite limited in most browsers and applications. Hopefully, that will change in the near future.. 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

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. So, rather than cluttering up your page with two sets of category links — one for category views and another for category feeds […] Continue reading »

Category LiveBookmarks Plugin

CLB+ Enthusiastic Firefox users enjoy the luxury of Live Bookmarks, a feature of Firefox that automatically discovers and updates RSS feeds. Web pages with available feeds are indicated by the orange feed icon located in the browser’s address bar. Clicking the feed icon presents a list of all available feeds for that particular webpage. Users then select which feeds they would like Firefox to bookmark, track, and automatically update. Makes subscribing stupid easy. Very handy indeed. Continue reading »

WordPress RDF Source Makeover

I love looking at beautiful source-code output. However WordPress tends to spit code out in random chunks, often leaving spaces, line breaks, and tabs littered throughout the source output. This messes things up. Lists don’t look like lists and logically written code often appears scattered along the page carelessly. Often, this is the result of poorly written PHP, which can be manipulated to write beautifully aligned code that looks as good as it works. Continue reading »
