  • Very good talk... maybe I'll use groovy instead of scala

    Thank you Ken for a very clear and down to earth talk and for reminding me what I liked about groovy when I first saw it a couple of years ago.
    I've been trying to push Scala into my workplace for the last year, but I failed. Too many hurdles, since Scala is a big gun language, and can replace java altogether, but it introduces a lot of new concepts for OO developers to absorb (while being asked to be super productive). We just couldn't find the time for it.
    So your talk led me to consider using groovy instead, and just allow its ease of use allow the guys both productivity and introduction to the more functional concepts out there, eventually, and for the entire shabang, I will still go with something like Scala, but for the getting some new concepts in (closures etc...) as well as some increased productivity, Groovy might be the way to go. One big thing still bothers me, and you mentioned it, the performance issue, when I check it, more then a year ago, it was very poor. Not sure it will past my tests today, but lets hope so...
    10x again.

    Great presentation, certainly made me look at Groovy with another eyes.

    Is the code used available for download?
