CU@UC07

I’ll be speaking at the upcoming 2007 MySQL Conference & Expo (Why they dropped the word User, who knows), this time with Guy Harrison (Author of many books including [MySQL Stored Procedures][1]). We will be talking on **MySQL for Oracle DBAs and Developers**.

Anyway, good friend Paul McCullagh, creator of PBXT will be also speaking on PrimeBase XT: Design and Implementation of a Transactional Storage Engine . He coined to me in an email “CU at the UC”. I’ve done a further level of refactoring, and added marketing. You can buy the shirt online here . (More colors including black and products coming, if you want it now, please ask).
