Keynote like multi-screen output in linux

I normally create my presentations using the beamer package in Latex compiling them into pdf, can't really imagine why would anyone use anything else. I use evince to display the pdf on a projector, but found it to be relatively basic.

I was looking for an application to display some meta-information like the remaining time and the preview of the next slide on my laptop while displaying the current slide on the projector, the way Keynote does it. I found the pdf_presenter_console application, it is fairly minimalistic but seems to do the trick for me.

PHP Fatal error: Class 'PDO' not found

When using SQLite with Php for the first time, you might get this error under /var/log/httpd/error_log (I was using a Fedora 13 machine). The trick is to install a package called "php-pdo" and then use the function.

yum install php-pdo

Hopefully it will save someone some heartache :)
