The second day of JavaOne ended up being not as draining as the first one, although I had lots of interesting times this day too. I’ve divided it into two blog posts – this is about what happened at JavaOne, and the next one will be about the Clojure meetup.
The first session of the day was Nick Siegers talk about using JRuby in production at Kenai. An interesting talk about some of the things that worked, and some of the things that didn’t work. A surprising number of decisions were given as fiat since they needed to use Sun products for many things.
After that Neal Ford gave a comparison between JRuby and Groovy. I don’t have much to say about this talk except it seemed that some of the things seemed to be a bit more complicated to achieve in Groovy, than in Ruby.
As it turns out, the next talk was my final talk of the day. This was Bob Lee (crazy bob) talking about references and garbage collection on the JVM. A very good talk, and I learned about how the Google Collections MapMaker actually solves some of my Ioke problems. I ended up integrating it during the evening and it works great.
The second day had fewer talks for me – but I still had a very good time and even learned some stuff. Nice.
