The UKOUG is one of my favorite conferences of the year: local, good size, GREAT presentations. If you want to attend this conference FOR FREE all you have to do is submit a paper and get accepted! The call for papers is open and there are only a couple of weeks left to get your ideas in. Any war stories, experiences, or if you feel you've a bit of technical expertise you'd like to share then get your ideas in.
Database, PL/SQL, ADF, Apex, Forms, security, cloud, mobile, UX are all hot topics for the Development stream, but its up to you if you think you have an interesting story to tell others.
I've submitted three already!
