A few links from the PHP & Open Source Security Conference that took place on June 11th:

Brilliant Button Maker is an online script that creates 80x15 buttons (or badges). It is based on the Bill Zeller's script.

Two more postings along the lines of Planet Express. These two are not as generic, they deal with WordPress only, how to create an aggregator around it.

"WordPress Aggregator Blog :: Want one?" is a tutorial on how to implement an aggregator. This implementation is based on the WordPress RSS Aggregatro from LughingMeme and the Magpie RSS parser.

FeedWordPress is a plugin that aggregates Atom and RSS feeds.

I just upgraded to WordPress 1.5, it all went quite smoth, just a few minor problems. The readme file states that you should remove all old files with the exception of the ones you modified. This is kind of vague, here is what I figured:

• keep the old wp-config.php, it has a few extra lines compared to the new one, but it works fine as it is
• if you uploaded images or other files then most likely they are in the wp-content folder, keep them
• if you installed plugins I guess you have to leave them there (not sure if they can cause problems in the new version) or uninstall them before the upgrade

A blog posting that is asking for a good PHP framework pointed me to an excellent article about template engines in PHP. I tend to agree with Brian Lozier that template engines on top of PHP do not make much sense.
