Yesterday talks were amazing. The most interesting talk was about glassfish architecture by Jerome Doches from Sun Microsystems. He talks a lot about low level architecture of glassfish v3, and what can be interested glassfish starts in 2-3 seconds, and …. Supports rail, phobos and some others application which are no java application, and it happens automatically. Another talk was about Hibernate Search and I write more about it later because it very advance topic and I want know more about it.
JMaki also made impression on me. It is very nice framework and if I must compare it to something you know, I would choose spring framework. jMaki is something as spring but for javaScript libraries. And of course jMaki topic lands on my to-know list 
Others talks was also very interesting about lucene, java db and performance (it faster than MySQL !!!) and the last one was about Java Benchmarking Tool build on JUnit. If I find some time I will look closer to this topic.
The best part was BOF sessions, and I choose a two session with Neal Gafter. He is responsible for java closures specification, we are talking about it nearly two hours, and now I 100% convinced to closures in java, next topic was about java puzzlers and Neal learn us a lot. After four hours (I didn’t recognize that) I take a walk to home, that was raining but Zurich is the beautiful city I ever seen, I make some photos and go sleep. Today social event day
And now I am waiting for Erich Gamma speak.
