You are correct, Java and Scala are very similar. In fact you can import Java into scala (and theoretically the other way around too).
Documentation... yea- that would be great... I'm trying to get the website migrated from CMS (current system) to a Jekyll based system similar to Zeppelin or Flink... in the mean time, everyone I think is kind of standing-by on writing new docs. Including me. The only named algorithm in the road map right now is GLM- talk to Saikat and Jim I think are taking a crack at that. You are free (and encouraged) to implement algorithms you already understand well. As far as ASF in GSoC, candidly I don't know for sure. I'm not super familiar with that initiative. You could ask on d...@community.apache.org - I remember seeing some chatter over there. best, tg Trevor Grant Data Scientist https://github.com/rawkintrevo http://stackexchange.com/users/3002022/rawkintrevo http://trevorgrant.org *"Fortunate is he, who is able to know the causes of things." -Virgil* On Sat, Feb 25, 2017 at 3:36 AM, Aditya <adityasarma...@gmail.com> wrote: > Hello Trevor, > > I have gone through the two links that you sent me.
