[This is the archive of live post during day 1of Daring Java at Developer Summit. ]

8:30 AM: Thej and me reached IISC, for the first time I am visiting this place, I have one word for it, AWESOME! Trees all over, this place is really cool. I wish someday I could come and join this institute.

9:00 AM: Meeting few people we know, this place is not like BarCamp, there are advertisements all around and we do not feel the same energy as we have in BarCamp. It seems most of the people are here because they did not have choice.

9:30 AM: Key Note speech, another set of advertisements. It’s about enterprise applications and Java. Learning about Enterprise Development Architecture; building application with JDK 1.6 and JEE 5, what IDEs we should use etc, same general stuff that we guys talk over coffee.

9:55 AM: got bored of the session, sitting outside next to garden. Plan to meet Alassandro from LightStreamer and want to interview him for YAP.

10:20 am: attending java performance myths session, seems to be very interesting. She is discussing Benchmarking, and she does not believe in it. There are many more parameters to look into., something like JVM and garbage collection.

Micro-benchmarking is the key, write small apps and test separately, but it might give you improper answers as integration will always yield you wrong results as JIT/JVM has a lot of role to play in it. Talking about Optimizing application, how to , why and where.

There are no universal performance truths. Premature optimization is not a great option, but we should not avoid it always, don’t wait till it’s all over. Always look for I/O operation, they are bottlenecks in most cases. Read the rest of this entry »
