While I was working on a new system for my WordPress newsletter, a system that uses its own custom feed (skipping FeedBurner which caused errors last week), I had to figure out how to exclude a category from my blogs regular feed as well as my homepage and some other pages. There’s a couple of »

While in a previous post I talked about WordPress database optimization, with this post I intend to show you how to improve your sites performance a bit more by hosting your javascripts with Google. This only works if you’re using jQuery, prototype or another library that is supported by Google’s AJAX Librararies API. While those »

Custom RSS feeds in WordPress

9 June 2009 by Joost de Valk » - 22 Comments

I use FeedBurner to track all my feed subscribers, but sometimes I want to provide a different feed to other people (without my feed signature for instance, or using excerpts instead of full feeds).

I’ve been working with a plugin that was mentioned on the wp-hackers list last week, called debug queries, to optimize the performance on some of my sites, including this one. The plugin was pretty easy to use, and I’ve improved a bit on it. I’ve sent the patch to Frank, who authored the original plugin, »

So when I moved to the (DV) server at MediaTemple, it turns out that my WP-Cron stopped working. I didn’t notice for a while, until I found out that the new version of Tweetbacks didn’t work for me anymore, and this was using wp-cron. The fix turned out to be very simple, after some debugging »

I recently moved from a MediaTemple Grid Server to a MediaTemple DV extreme, and in that move, I lost the ability to do automatic plugin updates, and it instead required me to enter my FTP info. As I use a gigantic amount of plugins, that becomes annoying very soon. So I decided to find out »

24 January 2009 by Joost de Valk » - 14 Comments

If you’re coding in PHP a lot, PHPXref is one of the coolest tools available. It allows you to browse large portions of source code, and find where functions, variables and constants are defined and referenced. As the PHPXref of WordPress I used to use isn’t available anymore, I decided a couple of weeks ago »
