NetBeans was certainly a disruptive force during JavaOne 2015.
That was most clearly and objectively evident during NetBeans Day itself, during Community Sunday. Several people failed to find the rooms where the NetBeans Day sessions were held—most of the sessions had to be moved to larger rooms, in some cases because the waiting list was so long that it eclipsed the number allowed to attend.
Originally, NetBeans Day had been assigned two rooms (because in the afternoon there were parallel tracks), room 309 and 310. Throughout the day, 310 would be used, while 309 was scheduled for the afternoon sessions that would run in parallel to the sessions in room 310. However, a few days before the conference, NetBeans Day was moved from 310 to 304, which was far larger and was able to hold around 700 attendees.
Sitting on the stage, this is what I saw, a mass of people:
Standing room only, in some of the sessions:
Aside from sessions featuring James Gosling talking about robots at sea, there were sessions about Java EE and Maven, with Martijn Verburg and Adam Bien, as well as sessions about Java on your phone, featuring several people including Johan Vos and Toni Epple.
On the party scene, there was a packed out Johnny Foley's, i.e., the Irish pub near the Hilton in San Francisco, where the NetBeans speakers and other NetBeans enthusiasts got together on the evening before NetBeans Day:
The above is a 7 second summary of a party that went on all night. Plus, the traditional GlassFish party in the Thirsty Bear turned into the GlassFish, NetBeans, and OTN party, with several NetBeans Dream Team members helping out, including Sven, Zoran, Florian, and Martin.
Also, of course, there was the brand new NetBeans t-shirt with the brand new community-created logo "NetBeans Fits the Pieces Together":
And the above was before the conference even kicked off! See all the NetBeans sessions here, where people spoke working on projects at NASA, the US military, US navy, and many other large enterprise organizations, including Oracle customers, about where and why and how NetBeans, as a development environment and application framework, is simply awesome!
There were also several people joining the NetBeans events for the first time, especially Georgia Ingham and Sophia Matarazzo, both from the amazing IDR Solutions crew, led by Mark Stephens. They did their first session ever at JavaOne, about how NetBeans IDE is an awesome development tool for their needs.
It was an excellent week. I'd really like to thank everyone involved, it was a brilliant time. In particular, the core group of NetBeans enthusiasts, I'd like to thank a lot, most of whom (but by no means all, e.g., Toni, Mark and co, Paul & Gail, and Adam had already left the conference, as well as several others) were at the closing party at the Thirsty Bear:
Looking forward to next year, while really struggling to wrap my head around how we can do even better than we did at JavaOne 2015.
