The Zend Developer Zone has posted the latest episode in their "ZendCon Sessions" podcast series (as recorded at last year's ZendCon conference) - Brian DeShong's talk titled "Rickroll To Go With PHP, WURFL, and Other Open Source Tools".

Welcome to the ZendCon 2008 edition of the ZendCon Sessions. The ZendCon Sessions are live recordings of sessions that have been given at previous Zend Conferences. Combined with the slides, they can be the next best thing to having attended the conference itself. [...] This episode of The ZendCon Sessions was recorded live at ZendCon 2008 in Santa Clara, CA and features Brian DeShong giving his talk: "Rickroll To Go With PHP, WURFL, and Other Open Source Tools"
