I started off pretty late for my Day-2 (summit’s Day-3) at the summit, courtesy- extended sleeping 😀 😀 But I somehow managed to not miss much of the first session. The first session I attended today was “Introduction to JRuby” which was delivered by Ola Bini. He spoke about Ruby and its features like Blocks, Modules, Mixins among others. He then spoke about JRuby and how it eliminates the pain of using Java and leverages on the ease of Ruby. JRuby is basically Ruby running on JVM. This was developed keeping in mind the old legacy JavaEE based applications.
