Scott MacVicar shares a helpful hint for the PHP speakers out there - how to apply syntax highlighting to the code in your slides.

I use Apple's Keynote for doing my presentations and naturally these include some bits of code that need highlighting so that it’s easier to read. [...] In the end I used GESHI which is a highlight library written in PHP that supports the syntax highlighting of around 50 different programming and scripting languages.

He's provided his sample implementation to help you get up and running. You'll need to download and install GESHI to get it working though. Here's an example of the output.

Sandro Groganz has two new WordPress tips for users out there looking to do some syntax highlighting in their posts and that want to move some older permalinks into a WordPress environment.

The first post spotlights a package that makes highlighting in WordPress simple - the iG:Syntax Hiliter v3.5 plugin. He includes some sample code to show how the CSS is formatted which, in itself, is a demo of what the plugin looks like.

The second article follows the steps he went through to make the move to WordPress URLs from the previous format. He leaned toward mod_rewrite, but decided to go a different way and whip up a custom 404 handler to get people where they want to go. He includes the code (all 15 lines of it) to show how he did it.
