Hi Attila, Thanks for sharing that thread (disclaimer, yeah I'm the CEO at jClarity now) - I thought I knew a little about this space but definitely got given a masterclass by Gil et al.
Happy to do the Java Advent post again this year - was great fun last time! Do you want me to write the wrapper post for the last day again? *waves at the Posse* - hey guys, missed you at JavaOne, but Belgian beer awaits us shortly at Devoxx :-) Cheers, Martijn On 5 October 2013 15:42, Attila-Mihaly Balazs <dify....@gmail.com> wrote: > Hi all, > > I'm reposting the message here since (a) I didn't get any answer when > posting it to the javaposse gmail address (b) comments are not enabled on > the forums and (c) it might be of more general interest. > > Here it goes: > > Just wanted to chime in regarding references.
