During the Linux Conference mini conf days held on Monday and Tuesday @chrsjnr ran a day of talks about open source code. Adam Harvey from php.net presented a talk in which he was inspired by a talk given at Pycon last year on the state of Python. It is presented in a tongue and check way and very well done. If your a PHP fan or not it is worth a watch and a good laugh.
