Welcome to "The Zone". Here's what the new JavaOne and Oracle Develop registration Website says:
The world's most important developer conferences are creating the world's coolest neighborhood for the developer community.
Having been intimately involved in the planning process, I can vouch for that statement.
Remember, if either co-located conference - JavaOne or Oracle Develop - are the confines of your interest, you can experience either one in standalone mode, if you like (although there are some areas of common interest, of course). Or, considering that a single Full Conference Pass gives you access to both of them, you can partake in any measure that you like. It's up to you.
Either way, you will get access not only to session content and keynotes, but also to the massive OTN Night party on Monday night, to open unconference sessions, and to the legendary Appreciate Night concert (acts TBD) on Wednesday.
Furthermore, as is customary, the Oracle Technology Network team will offer a full slate of community-focused activities and goodies while the conferences are running - more details on those as we have them.
A GOOD time is ensured for all; I look forward to seeing you there!
