YAPC::EU::2005 Proceedings
Yes, I am talking about YAPC::EU::2005. This Yapc was organized in Braga, Portugal, and during this Yapc a proceedings book with some articles was distributed to all participants. It has 235 pages devoted to Perl, and I am sure some of them are still actual.
Yesterday I went digging my archives and mailboxes, searching for the original PDF and, fortunately, I found it. Therefore, you can create your own personal backup copy. Just follow the link above.
I blog about Perl. D'uh!
Great doc! You're right, some of it is still current, and even when it isn't, it makes for good reading anyway. I specially liked the optimization part by Nick Clark.
