From Movember to UKOUG, Pythian is stomping the grounds with massive thuds. This Log Buffer #297 collects various great blog posts from across the database world once again. Enjoy the Log Buffer Editions.
Time for my user group rant again. Every time I am poised on the edge of taking another pilgrimage to an Oracle technical event I descend into this user group smoke screen ( a good thing) and spout rhetoric about how amazingly valuable they are.

If you’re like me and are a DBA in the UK with a penchant for MySQL or Oracle, you’ll know we have a smörgåsbord of conferences here next week. We’ve been waiting, and like buses two have come at once. We have the UK Oracle User Group Conference 2012, in Birmingham on 3rd – 5th December 2012, and the Percona Live London MySQL Conference running on 3rd – 4th December. Pythian will be speaking at both events.
