Huzzah! It’s official, Perl 5.12 is out! If you haven’t already, check out the changelog! As one might expect, this little piece of news made its way on several blogs, both internal and external to the Perl community.
I have successfully compiled and installed DBD::Oracle on Windows 2008 Server 64bit operating system today.

Here’s a sneak peek at a video matrix — this is all the videos that include Pythian Group employees at the MySQL conference. I hope to have all the rest of the videos processed and uploaded within 24 hours, with a matrix similar to the one below (but of course with many more sessions).
