The conference took place in Multikino Cinema, so you can imagine massively big rooms, immense display sizes… To me, it’s been one of the most impressive locations together with Phantasialand for JavaLand. But even though, with so many people around, any place feels small sometimes. There were sessions extremely packed, with people sitting on the floor.
The meals were served in different rooms, but it was a bit uncomfortable to eat it sitting without tables.
As for the city, I didn’t have time to do tourism, but the old town of Krakow and nearby streets looked great.
One does not simply organise a conference for 1,500+ people. It’s not an easy job, and the GeeCON crew did extremely well. Everything ran smoothly and on a timely manner. On the other hand, there was one official party for everybody and 3 speaker dinners! I’ve never been in a conference taking care of the speakers every night. And not only that, for the spent that spent the post-weekend in Krakow, they organised a tourism trip!

Scale your web applications with Servlet 3.1 Async I/O, by Simone Bordet. It was very useful for me to understand that, although the Servlet API is catching up with modern approaches like Netty, it still needs time to get there. So it might be an option for applications already using the Servlet API, but definitely not for high performance applications where you would a totally async framework like Vert.x or Ratpack.
